Description

  The present invention relates to a processing apparatus that processes a workpiece, and more particularly, to a processing apparatus that transmits and receives information related to a processing operation, an information communication system thereof, and a control program for the processing apparatus.

  There are various types of so-called processing devices that perform processing on a workpiece. For example, a sewing device that performs sewing on a workpiece, a machine tool that works a workpiece, a machine that performs surface treatment such as polishing and cleaning, etc. Etc.

  As an example, there are a wide variety of sewing objects (for example, cloth and leather) that are workpieces of the sewing apparatus within the scope of application of the sewing apparatus, and a sewing material ( For example, there are various types of thread and the like within the same application target range depending on the mode of sewing by the user and the specifications of the sewing apparatus. In addition, regarding various processing setting values (sewing setting values) of processing conditions (sewing conditions) to be set in the sewing apparatus at that time, the optimum conditions differ depending on the type of sewing product and the sewing mode.

  Conventionally, sewing is performed while appropriately selecting processing setting values (sewing setting values) such as the type of sewing, thread tension, and cloth feed amount according to the type of fabric (fabric) of various types of sewing products. As an example of a sewing apparatus, there exists a thing of patent document 1, for example. In this prior art, the sewing method and the type of fabric are displayed on the liquid crystal display device. When the operator selects from the displayed sewing method and fabric type with the selection operation switch, a list of various setting values of the sewing device suitable for the combination of the selected sewing method and fabric is displayed on the liquid crystal display device. It has become.

JP-A-6-142355 (paragraph numbers 0024 to 0044, FIGS. 6 to 18)

  In the above prior art, when the sewing method and the type of fabric are designated, a set value of various sewing conditions suitable for the designated combination is displayed in a list, and by setting the values accordingly, workability is relatively good. Sewing can be performed, and a sewing product with a certain level of good quality can be completed.

  However, the above prior art exemplifies typical patterns of some limited set values that are likely to obtain a relatively good quality sewing product depending on the combination of sewing method and fabric type. It ’s just that. Therefore, it is difficult to say that the relationship between the detailed setting values related to the sewing conditions and the properties of the resultant sewing product is clearly related, and the work piece processed by a certain processing operator (sewing manufacturer) ( It has been difficult for others to easily and accurately understand the properties of the sewing product) and the processing conditions corresponding thereto.

  For this reason, for example, when a processing failure occurs under a user far away from the manufacturer of the processing apparatus, a service person goes to the remote user from the manufacturer side or sends the entire processing apparatus to the manufacturer. Without it, it was difficult for the manufacturer to investigate the cause of processing defects. In addition, even if there is a machining operator who has excellent machining know-how in machining using a machining apparatus, it is difficult to convey the know-how to other machining workers and gain knowledge.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a processing apparatus that can be easily and accurately understood by another person as a set of the properties of the workpiece processed by the processing operator and the processing conditions corresponding thereto, and its information communication system and control of the processing apparatus. To provide a program.

  In order to achieve the above object, according to a first aspect of the present invention, in a processing apparatus for processing a workpiece, information on the processed processing conditions is obtained at a predetermined predetermined stage after the start of processing on the workpiece. Further, the present invention is characterized in that it has processing information writing means capable of transmitting and writing to a wireless tag attached to the workpiece without contact via wireless communication.

  In the first invention of this application, when the processing worker starts processing the workpiece using the processing device and enters a predetermined stage such as after the end of processing or just before the end of processing, the processing information is written by the processing information writing means. Information about the condition is written on a wireless tag attached to the workpiece. As a result, when the workpiece attached to the wireless tag is subsequently obtained by another person, not only the property of the workpiece can be observed on the ground, but also the processing conditions previously written by the processing information reading means, for example. By reading the information from the wireless tag, it is possible to know in detail what processing conditions the workpiece having the property has been processed. That is, another person can easily and accurately understand the properties of the workpiece processed by the processing operator and the processing conditions corresponding to the properties. As a result, for example, even when a processing failure occurs under a user far away from the manufacturer of the processing device, the processing condition information when the processing failure occurs is stored in the wireless tag attached to the processing failure product. Because it is written, even if a service person does not bother to the remote user from the manufacturer side or send the entire processing device to the manufacturer, send the defective product and wireless tag to the manufacturer The manufacturer can easily find out the cause of the processing failure. Furthermore, if the manufacturer performs the correct processing with the correct processing conditions on the defective product, the correct processing condition information is written to the accompanying wireless tag (processing condition guidance), so the user sent back from the manufacturer Can acquire the correct processing conditions from the wireless tag and perform correct processing again. Even if the processing method is unknown on the user side, if the unprocessed workpiece and the wireless tag are sent to the manufacturer side, the processing is performed on the manufacturer side and the processing method is written to the wireless tag and sent back. Processing conditions can be taught. Also, for example, if there is a processing worker who has excellent processing know-how in processing using a processing device, and if at least one excellent processing sample is manufactured using that know-how, the processing sample is manufactured Is written on the wireless tag attached to the processed sample as processing condition information, so other processing workers can obtain the processing know-how just by obtaining the processed sample and wireless tag. Can be easily understood.

  According to a second invention, in the first invention described above, the processing information writing means is controlled to write information on the processing conditions to the wireless tag when the predetermined stage is reached after the processing of the workpiece is started. It further has a writing control means for performing.

  At a predetermined stage after the start of machining, information on the machining conditions at that time is automatically written in a wireless tag attached to the workpiece by the machining information writing means, and the properties of the workpiece and the corresponding machining conditions are set. As others can understand easily and accurately.

  3rd invention WHEREIN: In the said 1st invention, when it becomes the said predetermined | prescribed stage after the process start of the said workpiece, whether the information regarding the said process conditions may be written in the said radio | wireless tag. Confirmation processing means for performing a confirmation operation input of the processing information, the processing information writing means, the information of the processing conditions when the confirmation operation input of the operator through the confirmation operation means is performed It is characterized by writing.

  At a predetermined stage after the start of processing, based on the operator's confirmation operation input, information on the processing conditions at that time is written to the wireless tag attached to the workpiece by the processing information writing means, and the properties of the workpiece and Others can easily and accurately understand the corresponding processing conditions as a set.

  A fourth invention is characterized in that, in the second or third invention, the processing information writing means overwrites and updates the information on the processing conditions stored in the wireless tag every time it is written.

  Thereby, the last written information can be automatically recorded on the wireless tag as the latest information or the best information regarding the processing conditions.

  According to a fifth invention, in the second or third invention, the processing information writing unit accumulates each information in the wireless tag so that the information can be read each time information on the processing conditions is written. .

  As a result, regardless of the order of writing and the timing, all of the written processing information can be recorded on the wireless tag without being received.

  In a sixth aspect based on the first aspect, the processing information writing means is a label that can be attached to at least one of the workpiece, the packaging of the workpiece, and an attachment of the workpiece. Information on the processing conditions is written to the wireless tag provided.

  Based on the processing information of the RFID tag of the label affixed to the workpiece, its packaging, ancillary documents, etc., the other person sets the properties of the workpiece processed by the processing operator and the corresponding processing conditions as a set. Can be easily and accurately understood.

  In a seventh aspect based on the first aspect, information relating to a processing condition at the time of processing stored in a wireless tag attached to a workpiece processed by another processing apparatus is read in a non-contact manner via wireless communication. The apparatus further includes processing information reading means and storage means for storing information relating to the read processing conditions.

  For example, if there is a processing operator who has excellent processing know-how in processing using a processing device, if one excellent processing sample is manufactured using that know-how, the processing sample will be excellent. Know-how is written in the wireless tag attached to the processed sample as processing condition information. Then, the other processing operator who has obtained the processing sample and the wireless tag reads the processing condition information related to the processing sample stored in the wireless tag by the processing information reading means in his processing apparatus and reads it into the storage means. By memorizing, the machining know-how can be easily obtained, and good machining can be easily reproduced under the same excellent machining conditions in own machining. In addition, at this time, the other processing workers can confirm whether the conditions are the necessary conditions in their processing equipment by visually checking the workmanship of the processing sample, and ensure the necessary processing know-how. I can understand. Also, for example, when a processing failure occurs under a user far away from the manufacturer of the processing device, the processing condition information when the processing failure occurs is written on the wireless tag attached to the processing failure product If the defective processing product and the wireless tag are sent to the manufacturer, the processing condition in which the processing failure has occurred in the processing information reading means in the processing apparatus on the manufacturer side can be read and stored in the storing means. This makes it possible for the manufacturer to easily investigate the cause of the processing failure even if the service person does not bother to reach the remote user from the manufacturer or send the entire processing device to the manufacturer. it can.

  An eighth invention according to the seventh invention further includes a change operation means for performing a change operation input based on a machining condition in the other machining apparatus read by the machining information reading means or stored in the storage means. And the said memory | storage means memorize | stores the process conditions changed by the said change operation means.

  For example, even if a processing operator who has obtained a processing sample and a wireless tag in another processing apparatus reads the processing condition information related to the processing sample directly in his processing apparatus and performs processing, the processing apparatus and the processing sample Due to individual differences with other processing equipment in which this product is manufactured, the same processability may not be obtained. Therefore, in the eighth invention of the present application, the change operation means can input a change operation based on the processing conditions in another processing apparatus, and the storage means stores the changed processing conditions. As a result, it is possible to compensate for a decrease in workability that may be caused by the individual differences by newly correcting, updating, and adding necessary machining conditions in the processing apparatus, and to surely obtain excellent workability. In the eighth invention of the present application, for example, when the processing condition information when a processing failure occurs under a far away user is written and sent to the wireless tag attached to the processing failure product, the manufacturer side In this machining apparatus, the machining conditions at the time of occurrence of a defective product can be changed and corrected by the change operation means to manufacture a correct workpiece, and the changed and corrected machining conditions can be stored in the storage means.

  A ninth invention further comprises a change operation means for performing a change operation input based on a machining condition in the other machining apparatus read by the machining information reading means or stored in the storage means in the seventh invention. The processing information writing means transmits the processing conditions changed by the change operation means to a wireless tag attached to the workpiece and writes the processing conditions.

  For example, even if a processing operator who has obtained a processing sample and a wireless tag in another processing apparatus reads the processing condition information related to the processing sample directly in his processing apparatus and performs processing, the processing apparatus and the processing sample Due to individual differences such as dimensional errors, mounting accuracy errors, friction and wear conditions with other processing devices where this product is manufactured, the same workability may not be obtained. Therefore, in the ninth invention of the present application, the change operation means enables a change operation input based on the processing conditions in another processing apparatus, and writes the changed processing conditions in a wireless tag attached to the workpiece. As a result, it is possible to compensate for a decrease in workability that may be caused by the individual differences by newly correcting, updating, and adding necessary machining conditions in the processing apparatus, and to surely obtain excellent workability. In addition, by attaching a wireless tag that has been modified and modified once in this way to the processed sample, it is corrected once another person reads in the processing condition information related to the processed sample. As a result, it is possible to obtain an excellent workability with certainty.

  Further, in the ninth invention of the present application, for example, when processing condition information when a processing failure occurs under a far away user is written and sent to a wireless tag attached to the processing failure product, In the processing apparatus, the correct operation product can be manufactured by changing and correcting the processing condition when the processing defect occurs by the change operation means. Further, by storing the modified and modified processing conditions in the wireless tag of the correctly processed product, the user can reliably acquire the correct processing conditions from the wireless tag by sending the processed product and the wireless tag back to the user side. The correct processing can be performed.

  According to a tenth aspect of the present invention, in the first aspect of the invention, the apparatus main body, a mounting part that is directly or indirectly attached to the apparatus main body, and a wireless tag attached to a workpiece processed by another processing apparatus are stored. In addition, information on the mounting part used at the time of processing is read into the information on the mounting part used at the time of processing read by the part information reading means at the time of processing read by the non-contact processing part information reading means via wireless communication. Based on the above, it is further characterized by further comprising notifying means for notifying the attachment part necessary for processing.

  For example, processing part information reading means reads, for example, attachment part information necessary when a processing sample is manufactured by another processing apparatus from a wireless tag, and a notification means notifies accordingly, for example, processing It is possible to ensure that the necessary mounting parts are provided to achieve the same good workability as the properly processed product sent from the sample or the manufacturer.

  An eleventh invention is characterized in that, in the tenth invention, the notification means is configured to be able to execute the notification even during operation of the machining apparatus.

  Accordingly, it is possible to notify parts necessary for processing without stopping the processing apparatus, so that productivity can be improved.

  In a twelfth aspect according to the first aspect, the apparatus further includes an apparatus main body, an attachment part that is directly or indirectly attached to the apparatus body, and a detection unit that identifies the attachment part. Is characterized in that information relating to the identification result of the attachment part by the detection means is transmitted and written to the wireless tag.

  In the twelfth invention of this application, when the processing condition information is written in the wireless tag by the processing information writing means, attachment information of the attachment component identified by the detection means is also written in the wireless tag. As a result, other processing operators who have read the information from the wireless tag afterwards can ensure the necessary parts to achieve the same good workability as the previously manufactured processing sample and the manufacturer's normal processing product. It becomes possible to specify.

  A thirteenth aspect of the invention corresponds to the first aspect of the invention from the apparatus main body, an attachment part that is directly or indirectly attached to the apparatus body, and a wireless tag that is provided so as to be handled in association with the attachment part. The component information reading means for reading the type identification information or the individual identification information of the attachment component, and the attachment in which the type identification information or the individual identification information read by the component information reading means is assumed in advance as an attachment target of the apparatus main body. A first restriction signal generating means for generating a signal for applying a predetermined restriction set in advance for the unexpected part to the operation of the apparatus main body when the part does not correspond to a part; To do.

  The first limit signal generating means generates and outputs a signal for applying a predetermined limit set in advance for a part that is not preliminarily assumed as an attachment target (for example, a non-genuine part), thereby outputting a non-genuine part Even if is used, the apparatus does not become inoperable, and it is possible to ensure the minimum necessary apparatus performance while preventing the occurrence of a failure due to a decrease in durability.

  In a fourteenth aspect based on the thirteenth aspect, when the first restriction signal generating unit cannot read the type identification information or the individual identification information of the attachment component by the component information reading unit, the operation of the apparatus main body is performed. On the other hand, a signal for adding a predetermined limit set in advance for the unexpected part is generated.

  For example, when a part without a corresponding wireless tag is used, such as a so-called pirated copy or counterfeit product, the device will not become inoperable, and it will not cause a failure due to a decrease in durability. As a result, the minimum required device performance can be ensured.

  15th invention respond | corresponds from the radio | wireless tag provided so that it might handle in connection with this apparatus main body, the attachment part directly or indirectly attached to this apparatus main body, and this attachment part in the said 1st invention. Usage information reading means for reading usage information related to the usage history of the attachment parts, and when the usage information read by the usage information reading means has reached a preset time condition, On the other hand, it has the 2nd restriction | limiting signal production | generation means which produces | generates the signal for adding the preset predetermined | prescribed restriction | limiting.

  The second limit signal generation means makes it difficult to achieve such durability by generating and outputting a signal for applying a predetermined limit set in advance for, for example, a mounting component whose service life has reached (or is approaching). Even if a certain part is used, the apparatus does not become inoperable, and it is possible to ensure the minimum necessary apparatus performance while preventing the occurrence of a failure due to a decrease in durability.

  In a sixteenth aspect based on any one of the thirteenth to fifteenth aspects, the first or second restriction signal generating means starts the operation of the apparatus body as a signal for applying the predetermined restriction. A signal for prohibiting is generated.

  Operate by preventing the device body from operating when a genuine or pirated mounting component that is not supposed to be mounted in advance, for example, or when a mounting component that has reached the end of its useful life is used (or approached) It is possible to reliably prevent the occurrence of defects and failures.

  In a seventeenth aspect based on any one of the thirteenth to sixteenth aspects, the first or second restriction signal generating means informs that the predetermined restriction is applied before the predetermined restriction is applied. A signal for informing a subject is generated.

  Thereby, thereafter, the operation can be restricted and the operator can be surely recognized in advance that it is difficult to achieve the original performance.

  In an eighteenth aspect according to any one of the thirteenth to seventeenth aspects, is the first or second restriction signal generation means may apply the predetermined restriction before applying the predetermined restriction? A signal for generating a display for prompting confirmation of whether or not is generated.

  Thereby, thereafter, the operation can be restricted and the operator can be surely recognized in advance that it is difficult to achieve the original performance.

  In a nineteenth aspect based on any one of the thirteenth to eighteenth aspects, the first or second restriction signal generating means applies the predetermined restriction when the predetermined restriction is applied. A signal for informing the notification target person of the fact is generated.

  Thus, even when notification or confirmation display is not performed before the operation is restricted, the operator can be surely recognized that the operation is currently restricted and the original performance is hardly achieved.

  A twentieth aspect of the present invention is the sewing apparatus according to any one of the first to nineteenth aspects of the present invention, which is a sewing apparatus that performs sewing on a workpiece.

  In the sewing apparatus, others can easily and accurately understand the properties of the sewing product sewn by the sewing manufacturer and the corresponding sewing conditions.

  In a twenty-first aspect, in any one of the thirteenth to sixteenth aspects, the sewing speed of the apparatus main body is decreased as the signal for applying the predetermined restriction as the first or second restriction signal generating means. Or a sewing device comprising means for generating a signal for reducing the upper limit of the sewing speed.

  As a result, it is possible to ensure the minimum sewing performance while preventing the occurrence of defective sewing or failure due to a decrease in durability.

  According to a twenty-second invention, in the twenty-first invention, from a wireless tag provided so as to be handled in association with a workpiece or a sewing material as the workpiece, the corresponding kind of the sewing product or the sewing material Sewing information reading means for reading identification information or individual identification information, and when the type identification information or the individual identification information read by the sewing information reading means does not correspond to what is assumed in advance as a target to be used during sewing, And third restriction signal generating means for generating a signal for reducing the sewing speed of the apparatus main body or reducing the upper limit of the sewing speed.

  Preliminarily assumed as a sewing object or a use object at the time of sewing by generating and outputting a signal for lowering the sewing speed of the apparatus body or lowering the upper limit of the sewing speed by the third restriction signal generating means The device will not be unable to sew even if it is not used (for example, inferior goods or deteriorated goods), and the minimum sewing performance will be ensured while preventing the occurrence of malfunctions due to a decrease in durability. be able to.

  In a twenty-third aspect of the present invention, in any one of the thirteenth to fifteenth aspects, information relating to the use of the attachment part in the device main body is not transmitted to the wireless tag corresponding to the attachment part. It further has usage information writing means for transmitting and writing via wireless communication by contact.

  By writing information such as the usage history of the attached component to the corresponding wireless tag, it is possible to appropriately manage the attached component according to the usage status.

  In a twenty-fourth aspect based on the twenty-third aspect, the usage information writing means transmits information on the number of times or the usage time the mounting part has been used in the apparatus body as information related to the usage. It is characterized by writing.

As a result, when the workpiece attached to the wireless tag is subsequently obtained by another person, not only the property of the workpiece can be observed on the ground, but also the processing conditions previously written by the processing information reading means, for example. By reading the information from the wireless tag, it is possible to know in detail what processing conditions the workpiece having the property has been processed. That is, another person can easily and accurately understand the properties of the workpiece processed by the processing operator and the processing conditions corresponding to the properties.

  As a result, for example, even when a processing failure occurs under a user far away from the manufacturer of the processing device, the processing condition information when the processing failure occurs is stored in the wireless tag attached to the processing failure product. Because it is written, even if a service person does not bother to the remote user from the manufacturer side or send the entire processing device to the manufacturer, send the defective product and wireless tag to the manufacturer The manufacturer can easily find out the cause of the processing failure.

  Further, based on appropriate operations on the operation panel 15 side (details will be described later), various set values relating to the sewing conditions when the sewing object C is sewn by the tag reader / writer 50 are set to the sewing apparatus main body M1 side (or From the article C to be sewn (or the approached state) attached to the sewing apparatus main body M1 to the IC circuit unit 100 of the wireless tag T1 having the above configuration, the data is stored and held.

  FIG. 9 is a flowchart showing a control procedure executed by the control device 17 of the sewing apparatus M based on the read information.

  In FIG. 9, first, in step S10, the RFID tag information (various set value information relating to the sewing conditions during the sewing operation) of the RFID tag T1 attached to the sewing product C read out by the reader / writer 50 as described above is captured. Identify with In this case, the sewing product C may already be of another sewing device (the same model as the sewing device M, may be the same manufacturer as the sewing device M, or may be another manufacturer). If the sewing has already been carried out, various setting values at that time are taken in (in this sense, it is a sewing product, but it is also a sewing product that has already been sewn). If no sewing has been performed on the workpiece C yet, nothing is captured, for example, 0 data is captured.

  Thereafter, in step S20, the identified various setting values are stored and stored in the RAM 17C, and in step S30, display control signals representing the stored various setting values are output to the operation panel 15.

  FIG. 10 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. In FIG. 10, “stitch length F”, “stitch pitch P”, “number of stitches N”, “pressing pressure p”, “thread tension s”, “sewing speed v1”, “cloth feed speed v2”, and “sewing area setting” are set. Each setting value is shown, and a “confirm” button for confirming this setting is also displayed.

  When the operator who sees the display performs an operation of confirming and inputting the setting (clicking the “confirm” button), the determination in the next step S40 is satisfied, and the process proceeds to step S50.

  In step S50, the RFID tag information of the RFID tag T2 read by the reader / writer 50 as described above (for example, the type identification information indicating the type of each component, or the individual identification information attached to each individual of the same type). Capture and identify.

  Thereafter, in step S60, referring to the predetermined combination suitability reference table stored in advance in the ROM 17B, the combination of the components 6, 7, and 32 identified from the RFID tag information recognized in step S50 is appropriate. It is determined whether or not.

  11 and 12 show an example of the combination suitability reference table.

  FIG. 11 shows an example of the suitability of the combination of the cloth presser 32 and the cutter 6 according to the size (L, M, S), and FIG. 12 shows the size (L, M, S) of the hammer 7 and the cutter 6. S) An example of suitability of another combination is shown.

  In FIG. 11, only a relatively small S size cutter 6 (see FIG. 14A) is suitable for the relatively small S size cloth presser 32 (see FIG. 13A). Therefore, the cutter 6 having a large L size (see FIG. 14C) and an intermediate M size (see FIG. 14B) is not suitable. Further, the S size and M size cutters 6 are suitable for the M size cloth presser 32 (see FIG. 13B), and the L size cutter 6 is not suitable. On the other hand, any of the S size, M size, and L size cutters 6 is suitable for the L size cloth presser 32 (see FIG. 13C). To summarize the above, in the three-stage size notation of S, M, and L, the case where the size of the cloth presser 32 is the same or larger than that of the cutter 6 is suitable and the size of the cloth presser 32 is small. Does not fit. This is because if the cloth presser 32 is relatively small in size, the cutter 6 interferes with the cloth presser 32 when forming the eyelet hole DH.

  The same applies to FIG. 12. In the three-stage size notation of S, M, and L, the case where the size of the hammer 7 is the same or larger than that of the cutter 6 is suitable, and the size of the hammer 7 is small. Is incompatible.

  Returning to FIG. 9, the determination in step S60 is performed as described above. If the combination is appropriate, the determination is satisfied, and the routine goes to step S70.

  In step S70, a display control signal for causing the display unit 15A of the operation panel 15 to display appropriateness is generated and output via the output interface 17E. FIG. 15 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. As shown in FIG. 15, in this case, it is displayed that there is no problem in the combination of the parts 6, 7, and 32 and whether or not it is possible to proceed to the creation of sewing data as it is, in order to confirm this The “Create data as is” and “Modify setting values” buttons are also displayed.

  If the operator who has seen this display performs an operation to correct the set value (clicks the “correct the set value” button), the determination in the next step S80 is not satisfied, and the process proceeds to step S90. In step S90, the above-mentioned sewing conditions “stitch length F”, “stitch pitch P”, “number of stitches N”, “pressing pressure p”, “thread tension s”, “s” set by the keys 15j, 15k, 15m on the operation panel 15 are set. The set values of “sewing speed v1”, “cloth feed speed v2” and “sewing area setting” are taken in and identified. Thereafter, in step S100, a display control signal for displaying the corrected / changed set value is generated and output via the output interface 17E.

  FIG. 16 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. In FIG. 16, in this example, among the set values (see 10) read in step S10 described above, the stitch length F is corrected / changed by the operation panel 15, and the value is ΔΔ [mm]. In addition, a “Yes” button that agrees with this change and a “No” button that disagrees are also displayed. When the operator who has seen this display has performed an operation for understanding the change (clicks the “Yes” button), the determination in the next step S110 is satisfied, and the set value after the change is stored in the RAM 17C in step S120. After storing and storing, the process proceeds to step S130.

  If the operator who has seen the above-described display of FIG. 15 performs an operation not to correct the setting (clicks the “create data as it is” button), the determination in step S80 is satisfied, and the step is continued. The process moves to S130.

  In step S130, the program storage area of the ROM 17B described above is set in accordance with various set values related to the above-described sewing conditions, the RFID tag information (type identification information) by the tag reader / writer 50, and the conformity determination result by them. Select and read out the optimum one from a plurality of stored eyelet stitching control programs (specifically, the CPU 17A generates a selection signal for selecting the control program as a sewing control signal and outputs it to the ROM 17B, A control program corresponding to this is read from the ROM 17B). Correspondingly, the most suitable one for the current sewing is appropriately selected from a plurality of stitch data (stitch condition data) stored in the stitch data storage area of the ROM 17B described above (in detail, The CPU 17A generates a selection signal for selecting the stitch data as a sewing control signal and outputs the selection signal to the ROM 17B, and the stitch data corresponding to the selection signal is read out from the ROM 17B. The sewing data (stitch data) in the present eyelet stitching is created. In this stitch data, for example, in order to determine the needle drop position of the outer needle with respect to the inner needle for each of a predetermined number of needles (17 needles in this example), the X-direction drive motor 28, the Y-direction drive motor 30, and θ The number of driving pulses of each direction driving motor 22 is set.

  FIG. 17 is a flowchart showing a detailed procedure for creating sewing data in step S130. As shown in FIG. 17, first in step S131, stitch data for the first stitch of the eyelet stitch is created, and this stitch data is newly stored in, for example, the data memory of the RAM 17C. Stitch data is created and stored in the same manner, and thereafter, the third stitch and the fourth stitch are advanced in the same manner, and finally the stitch data of the N + 1 stitch that becomes the predetermined number of stitches N + 1 (N = 17 in this example) is created. (Step S133) and this procedure is terminated.

  FIG. 18 is an explanatory diagram showing the contents of one example of stitch data for eyelet stitching created as described above, and FIG. 19 is a detailed configuration of the eyelet stitching formed on the work cloth. FIG.

  18 and 19, in this example, the first stitch 1N to the fifth stitch 5N among the 17 stitches are stitch data for the overlock stitching of the right foot FR, and the sixth stitch 6N to the thirteenth stitch 13N are the eyelet portions. This is stitch data for the DE stitching, and the 14th stitch 14N to 17th stitch 17N are stitch data for the stitching of the left foot FL.

  In FIG. 19, for example, the inner needle of the first stitch 1N is indicated by <1>, and the outer needle of the first stitch is indicated by (1). Further, as the movement direction of the feed base 8, the leftward movement of the feed base 8 in the X direction is defined as the “+” side, and the forward movement in the Y direction is defined as the “+” side. .

  Returning to FIG. 9, when the sewing data creation in step S130 as described above is completed, the process proceeds to step S140, where a display control signal having the same content as that shown in FIG. 18 is generated and output via the output interface 17E. Then, the display corresponding to the display unit 15A of the operation panel 15 is performed.

  Thereafter, the process proceeds to step S150, where an operation signal from the start / stop pedal 16 is identified, and it is determined whether the pedal 16 is depressed (turned on). When the determination is satisfied, the process proceeds to step S160, where the stitch data stored in the data memory of the RAM 17C is read for each stitch, and each stitch data is read from the program storage area of the ROM 17B which has been read out. While applying to the sewing control program, corresponding drive control signals as sewing control signals are generated and output to the motors 20, 22, 28, 30, 35, the servo solenoid 33, and the electromagnetic switching valve 25, and each is driven. Then, an operation corresponding to the sewing apparatus M is performed, and a sewing process is executed. That is, as shown in FIG. 19, the eyelet stitching made up of the right foot portion FR, the eyelet portion DE, and the left foot portion FL is carried out by moving the first stitch 1N to the 17th stitch 17N. The eye DN is sewn. When the sewing process in step S160 is completed, the process proceeds to step S170.

  In step S170, a display control signal for confirming whether or not the various set values at the time of the sewing work are stored (written) in the wireless tag T1 attached to the sewing product C is generated and output via the output interface 17E. Output.

  FIG. 20 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. In FIG. 20, the set values for the sewing work just completed, “stitch length F” “stitch pitch P” “number of stitches N” “pressing pressure p” “thread tension s” “sewing speed v1” “ The values of “cloth feed speed v2” and “sewing area setting” are shown again, and a “Yes” button that agrees to store this value in the wireless tag T1 and a “No” button that disagrees are also displayed.

  When the operator who has seen this display has performed an operation of accepting the storage (writing) process (clicked on the “Yes” button), the determination in the next step S180 is satisfied, and the process proceeds to step S190. In step S190, the above set values (various set value information relating to the sewing conditions during the sewing operation) are transmitted and written by the reader / writer 50 to the wireless tag T1 attached to the sewing product C, and this flow is finished. .

  If the operator who sees the display shown in FIG. 20 performs an operation that does not approve the storage (writing) process (clicks the “No” button), the writing process is not performed and this flow is immediately terminated. To do.

  On the other hand, if it is determined in the previous step S60 that the combination is not appropriate, the process proceeds to step S200. In step S200, it is determined from the RFID tag information recognized in step S50 whether the attached parts 6, 7, and 32 are genuine products of the manufacturer of the sewing apparatus M. When it is recognized that all the RFID tag information of the parts 6, 7, and 32 are genuine products, the process proceeds to step S210.

  In step S210, a display control signal for clearly indicating that component replacement should be performed to avoid the nonconformity is generated and output to the operation panel 15 via the output interface 17E. FIG. 21 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. FIG. 21 shows that the power should be turned off once and the cutter 6 should be changed from the L size to the S size. Furthermore, a “Yes” button for agreeing to the setting change and a “No” button for disagreeing are also shown. it's shown.

  If the operator who sees this display has performed an operation to accept the setting change (clicks the “Yes” button), the determination in the next step S220 is satisfied, and the process proceeds to step S230 to turn on the power of the entire sewing apparatus M. Is turned OFF, and this flow ends. The operator can replace parts by turning off the power. If the operator performs an operation not to accept the setting change (clicks the “No” button), the determination in step S220 is not satisfied, and the process proceeds to step S240.

  In step S240, referring to a predetermined combination suitability reference table stored in the ROM 17B in advance, the non-conformity is not assumed in advance as an attachment target without replacing any of the parts 6, 7, and 32. It is determined whether it can be avoided only by executing the sewing operation restriction on the sewing device M side set in advance (detailed explanation is omitted, but information on the existence of such avoidability is also included) Incorporated in the adequacy lookup table).

  If it cannot be avoided only by the operation restriction, the process returns to step S210 and the same procedure is repeated to notify the operator that the parts should be replaced. If it can be avoided only by the operation restriction, the determination in step S240 is satisfied, and the process proceeds to step S250.

  In step S250, a display control signal for clearly indicating a measure for performing the above avoidance is generated and output to the operation panel 15 via the output interface 17E. FIG. 22 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. In FIG. 22, among the current settings, the sewing speed v1 is forcibly limited to XX [mm / s] → △△ [mm / s], and this operation restriction is further shown. A “Yes” button to accept and a “No” button to disagree are also displayed.

  When the operator who sees this display performs an operation not to understand the operation restriction (clicks the “No” button), the determination in step S260 is not satisfied, and the same display is performed by returning to step S250 to perform the operation. If an operation is performed assuming that the restriction is accepted (the “Yes” button is clicked), the determination in step S260 is satisfied, and the process proceeds to step S130. As described above, the operation restriction is applied from the program storage area of the ROM 17B. Select and read the sewing program (operation restriction program) under operation restriction corresponding to. Correspondingly, a corresponding one of a plurality of stitch data stored in the stitch data storage area is selected as appropriate, and eyelet stitch sewing data under the current operation restriction is created. That is, in the above-described example, sewing data with corrections such that the sewing speed becomes v1ΔΔ [mm / s] is created, and thereafter, the same steps S140 to S190 as described above are executed.

  On the other hand, when it is recognized in step S200 that one of the RFID tag information of the parts 6, 7, and 32 is not genuine, or when the RFID tag information itself cannot be read by the tag reader / writer 50 ( If there is no recognition information), the determination at step S200 is not satisfied, and the routine goes to step S270.

  In step S270, the operator visually refers to a component that has been mounted (not recognized) without changing the setting value while referring to a predetermined combination suitability reference table stored in advance in the ROM 17B. It is determined whether or not it can be avoided under the condition of confirming with (detailed explanation is omitted, but information on the presence or absence of such avoidability is also incorporated in the suitability reference table).

  If it is possible to avoid by the confirmation on the operator side, the determination in step S270 is satisfied, the process proceeds to step S280, and the display control signal for clearly indicating the confirmation contents to be performed on the operator side (necessary for sewing, etc.) Corresponding to a signal for displaying a guidance of a necessary preparation operation), and outputs it to the operation panel 15 via the output interface 17E. FIG. 23 is a diagram illustrating an example of a screen display displayed on the display unit 15A at this time. In FIG. 23, in this example, when the RFID tag information of the cutter 6 is not recognized, a screen requesting to confirm whether or not it interferes with the cloth presser 32 when forming the eyelet hole DH of the cutter 6 is displayed. ing. In addition, a “Yes” button for accepting the confirmation request and a “No” button for disagreeing are also displayed.

  If the operator who sees this display performs an operation not to accept the confirmation request (clicks the “No” button), the determination in step S290 is not satisfied, and the same display is performed by returning to step S280 to confirm. If an operation is performed that the request is accepted (the “Yes” button is clicked), the determination in step S290 is satisfied, the process proceeds to step S130, and the above-described interference is not caused by the confirmation. To create sewing data. Thereafter, the same steps S130 to S190 as described above are executed.

  If it cannot be avoided by the confirmation from the operator side, the determination at step S270 is not satisfied, and the routine goes to step S300.

  In step S300, while referring to a predetermined combination suitability reference table stored in the ROM 17B in advance, the nonconformity regarding the non-genuine product is not replaced on the sewing apparatus M side without replacing the part (cutter 6 in the above example). It is determined whether it can be avoided only by executing a preset sewing operation restriction for non-genuine parts (detailed explanation is omitted, but information on the existence of such avoidance is also included) Incorporated in the adequacy lookup table).

  If it cannot be avoided due to the operation restriction, the process returns to step S210 and the same procedure is repeated to notify the operator that the parts should be replaced. If it can be avoided by the above operation restriction, the determination in step S300 is satisfied, and the process proceeds to step S250. Similarly to the above, a display control signal for clearly indicating a measure for performing the avoidance is generated and sent to the operation panel 15. The same procedure is followed.

  In the above, the workpiece C constitutes the workpiece described in each claim, and the sewing device M constitutes a processing device that processes the workpiece. Further, the wireless tag T1 constitutes a wireless tag attached to the workpiece, and the wireless tag T2 constitutes a wireless tag provided so as to be handled in association with an attachment part that is directly or indirectly attached to the apparatus main body. To do.

  In addition, the transmission unit 53 of the high-frequency circuit 51 of the tag reader / writer 50 constitutes processing information writing means that can transmit and write to a wireless tag attached to the workpiece without contact via wireless communication. Further, the processing information that the receiving unit 54 of the high-frequency circuit 51 reads the information on the processing conditions at the time of processing stored in the wireless tag attached to the workpiece processed by another processing apparatus in a non-contact manner via wireless communication. In addition to configuring the reading means, it also configures a part information reading means for reading the type identification information or individual identification information of the corresponding mounting part from a wireless tag provided so as to be handled in association with the mounting part. Sewing information reading means for reading the type identification information or individual identification information of the corresponding sewing object or sewing material from a wireless tag provided so as to be handled in association with the sewing object or sewing material as an object is also configured. Further, the entire tag reader / writer 50 also constitutes detection means for identifying a mounting part that is directly or indirectly attached to the apparatus main body.

  In addition, the control device 17 (particularly, the procedure of steps S160 and S170 in the flow of FIG. 9) performs processing so as to write information on processing conditions to the wireless tag when a predetermined stage is reached after processing of the workpiece is started. Writing control means for controlling the information writing means is configured. Further, the control device 17 (particularly, the procedure of step S130 through step S250 and step S260 in the flow of FIG. 9) assumes in advance the type identification information or individual identification information read by the component information reading means as an attachment target of the apparatus main body. If it does not correspond to the attached component, a first limit signal generating means for generating a signal for applying a predetermined limit set in advance for the unexpected component to the operation of the apparatus main body is configured. Further, the RAM 17C of the control device 17 constitutes storage means for storing information relating to the machining conditions read by the machining information reading means.

  Further, the numerical value down key 15m of the operation panel 15 constitutes a confirmation operation means for performing confirmation input for confirming whether or not information related to the processing conditions can be written to the wireless tag, and includes a select key 15j and a numerical value up key. 15k and the numerical value down key 15m constitute change operation means for performing change operation input based on the machining conditions in another machining apparatus read by the machining information reading means or stored in the storage means.

  The operational effects of the present embodiment described above will be described below.

  In the present embodiment, the sewing manufacturer starts sewing work on the sewing product C using the sewing apparatus M, and when the sewing is finished, the steps shown in FIG. 9 are performed in response to a manual operation input from the operation panel 15. In S190, each set value information (“stitch length F”, “stitch pitch P”, “number of stitches N”, “pressing pressure p”, “thread tension s”, “sewing speed v1”) is set by the tag reader / writer 50. “Values of“ cloth feed speed v2 ”and“ sewing area setting ”) are written in the wireless tag T1 attached to the workpiece C. As a result, when another person subsequently obtains the sewing product C to which the wireless tag T1 is attached, not only can the nature of the sewing product C be observed on the ground, but also, for example, provided in the sewing apparatus M that the user works on. By reading the sewing condition information previously written by the tag reader / writer 50 from the wireless tag T1, it is possible to know in detail what kind of sewing condition the article C to be sewn in has been sewn. . That is, another person can easily and accurately understand the property of the sewing product C sewn by the sewing manufacturer and the sewing conditions corresponding thereto.

  As a result, for example, as shown in FIG. 24, when a sewing failure fd occurs even when a sewing failure occurs under the user's sewing device Mu far from the manufacturer (owning the sewing device Mm). Since the sewing condition information is written in the wireless tag T1 associated with the sewing product Cu having the sewing defect fd (hereinafter, referred to as a defective sewing product as appropriate), the manufacturer has to bother the remote user. Even if a man does not crawl or send the entire sewing device Mu to the manufacturer, only the defective sewing product Cu and the wireless tag T1 (or the wireless tag T1 alone) are sent to the manufacturer (sewing on the manufacturer side). By reading the sewing condition information from the wireless tag T1 with the apparatus Mm, the cause of the occurrence of the sewing failure fd can be easily investigated by the manufacturer. Further, if correct sewing fcr is performed on the defective sewing product Cu by the manufacturer's sewing device Mm under correct sewing conditions, the correct sewing condition information is written and taught in the accompanying wireless tag T1 (correct sewing conditions). Therefore, the user who has been sent back from the manufacturer can read the teaching of the correct sewing condition from the wireless tag T1 with his sewing device Mu, and can perform correct sewing again. Even when the user does not know the sewing method at all, if the unsewn workpiece Cu (with wireless tag T1) is sent to the manufacturer, the manufacturer performs sewing and the sewing method is assigned to the wireless tag T1. It is also possible to teach sewing conditions (guidance for new sewing conditions) by writing back and sending back.

  At this time, in the present embodiment, since the data from the user side is read in step S10 of the flow of FIG. 9, the correct sewing conditions can be created by correcting the read data in steps S80 to S120. The above teaching work can be performed more easily (however, others can easily and easily set the properties of the sewing product C sewn by the sewing manufacturer, which is the original effect of the present invention, and the sewing conditions corresponding thereto) Such a read data correction function is not necessarily required as long as the effect of accurate understanding is obtained.

  Also, for example, in a sewing factory having a large number of sewing devices M as shown in FIG. 25, if there is a single sewing manufacturer (using the sewing device M-0) with excellent sewing know-how, use that know-how. If a sewing product C-0 having an excellent sewing fex is manufactured by the sewing apparatus M-0 (hereinafter referred to as a sewing sample as appropriate), a sewing sample C-0 having the sewing fex is manufactured. The excellent know-how is written in the RFID tag T1 attached to the sewing sample C-0 as sewing condition information in the sewing apparatus M-0. As a result, other sewing manufacturers (using sewing devices M-1, M-2, and M-3 in this example) have the sewing sample C-0 with the wireless tag T1 (or the wireless tag T1 alone). Just read the sewing conditions based on the excellent know-how from the wireless tag T1 with your own sewing devices M-1, M-2, M-3, and you can easily learn the excellent sewing know-how The sewing fex can be reproduced by its own sewing devices M-1, M-2, and M-3.

  It should be noted that at this time, dimensional errors, mounting accuracy errors, friction, wear conditions, etc., between the sewing devices M-1, M-2, M-3 and the sewing device M-0 from which the sewing sample C-0 is manufactured are described. Depending on individual differences, there is a possibility that the same sewing completion degree may not be obtained subtly as it is, but in the present embodiment, as described above, processing conditions newly required for the data read in steps S80 to S120 as described above. By correcting, updating, adding, etc., it is possible to compensate for a decrease in the degree of completion of sewing that may occur due to the individual differences, so that excellent sewing can be performed reliably.

  Further, at this time, the sewing machine M-0 side and the sewing machines M-1, M-2, M-3 side are separated from each other, or the usual use situation / mode is different or similar. However, in the case of a different model, the sewing sample M-0 cannot be directly acquired from the sewing machine M-0 on all of the sewing machines M-1, M-2, and M-3. Also good. That is, the sewing apparatus M-1 first directly acquires the sewing sample C-0 from the sewing apparatus M-0, slightly corrects the sewing conditions of the wireless tag T1, performs sewing, and stores the correction data in the wireless tag T1. If the correction data is further corrected by the sewing apparatus M-2, the sewing is performed and the correction data is stored in the wireless tag T1, and so on. The sewing devices M-2 and M-3 have an effect that the sewing device M-2 and M-3 have already been corrected once, so that an excellent degree of sewing completeness can be obtained with certainty (however, the present invention is effective). As long as the effect that the other person can easily and accurately understand the nature of the sewing product C sewn by the sewing manufacturer and the corresponding sewing conditions as a set, is obtained as described above. The read data correction function is not necessarily required. Do not).

  Further, in the present embodiment, the parts 6, 7, and 32 are not preliminarily assumed as attachment targets (non-genuine products or products of the same manufacturer but are not supposed to be attached) (information on the wireless tag T2). (Including the case where it cannot be recognized), the control program and the sewing data under the operation restriction that adds the predetermined operation restriction for such parts in step S240 and step S300 to step S250 are selected, and the final sewing data is selected. And sewing processing is performed in step S130. Thus, for example, even if parts 6, 7, and 32 that are not intended for attachment, such as genuine products, are used, sewing is not disabled, and sewing failure is prevented while not causing a failure due to a decrease in durability. The minimum sewing performance can be ensured. As a result, it is possible to improve the sewing work efficiency as compared with at least the case where sewing is impossible.

  In particular, when performing the above-described operation restriction, before adding the operation restriction, a display prompting confirmation input as to whether or not the operation restriction may be added is performed in step S250. Thereby, thereafter, the operation can be restricted and the operator can be surely recognized in advance that it is difficult to achieve the original performance. As a result, it is possible to avoid as much as possible the unreasonable use that causes a failure due to poor sewing or a decrease in durability, and it is possible to prevent a reduction in sewing work efficiency. In addition, as long as the effect that the other person can easily and accurately understand the nature of the sewing product C sewn by the sewing manufacturer and the corresponding sewing conditions as a set, which is the original effect of the present invention, is obtained. The operation restriction function as described above is not necessarily required.

  In the above embodiment, various set values relating to the sewing conditions, that is, “stitch length F”, “stitch pitch P”, “number of stitches N”, “pressing pressure p”, “thread tension s”, “sewing speed v1”, “ Each value of “cloth feed speed v2” and “sewing area setting” is written in the wireless tag T1 attached to the sewing product C. At this time, the mode of writing the wireless tag T1 to the IC circuit unit 100 is the writing mode. Overwrite and update each time (initialize each time and write a new one, or accumulate each time so that only the last data can be read, etc.), or read all information every time the RFID tag T1 is read You may make it accumulate and store one after another. In the former case, the last written information can be automatically recorded on the wireless tag T1 as the latest information or the best information on the sewing conditions. In the latter case, the written information can be written regardless of the writing order or timing. All the sewing condition information can be recorded in the wireless tag T1.

  In the above-described embodiment, various set value information related to the sewing conditions is detected and written in the wireless tag T1 after the sewing work is finished. However, the present invention is not limited to this. Also good. In short, it is only necessary to be at a stage that can be clearly associated with the sewing process that caused the property of the sewing product C to be formed. The predetermined stage is sufficient.

  Further, in the above description, the RFID tag T1 is provided on the label attached to the sewing product C. However, the present invention is not limited to this, and the packaging (packaging) of the sewing product C or the attached document of the sewing product C is not limited thereto. It may be provided on a label affixed to or the like. Similarly, the wireless tag T2 is not limited to the label attached to the parts 6, 7, 32, but is attached to the packaging (packaging) of the parts 6, 7, 32 or the attachments of the parts 6, 7, 32, etc. It may be provided on the label. Further, it may be directly attached without using a label, and is not limited to attachment, and may be fixed to the sewing product C with stitches (threads) or stapled. In any case, it suffices if it is provided to be sewn product C and parts 6, 7 and 32 (so as to be handled accompanyingly).

  In the above description, the wireless tag T1 stores only various set value information related to the sewing conditions. However, the present invention is not limited to this. That is, the wireless tag T1 stores in advance the sewing device mounting part information (for example, type identification information and individual identification information on the parts 6, 7, and 32 of the sewing apparatus M) used when the sewing condition information is stored. It may be stored and read together with the above-mentioned sewing condition information by the tag reader / writer 50 (in this case, the receiving unit 53 of the high-frequency generation circuit 51 of the tag reader / writer 50 is processed by another processing device). A processing part information reading unit is configured to read, in a non-contact manner, information related to a mounting part used at the time of processing stored in a wireless tag attached to the workpiece via wireless communication). And based on the information regarding such attachment parts 6, 7, and 32, the control apparatus 17 performs the notification regarding the attachment parts 6, 7, and 32 by the predetermined alerting | reporting means provided in the sewing apparatus M separately. It may be.

  Specifically, the line-up of the attachment parts 6, 7, and 32 at the time of writing the sewing condition information may be simply displayed on the display unit 15A of the operation panel 15, or the currently attached part read from the wireless tag T2. Items that are not sufficient in comparison with the type identification information and individual identification information of 6, 7, 32, or types, sizes, and inconsistencies may be displayed. In such a case, a warning or the like may be given. Good. These notifications / warnings may be displayed corresponding to the operation panel display unit 15A, or a buzzer or the like may be driven. By performing such notification, for example, it is necessary to realize a satisfactory sewing perfection level equivalent to the sewing sample C-0 described above and the workpiece Cu with the correct sewing fcr sent from the manufacturer. There is an effect that the attachment parts 6, 7, and 32 can be surely aligned. Further, it is preferable that the notification is configured to be executable even during the operation of the sewing apparatus M. In this case, since it is possible to notify the attachment parts 6, 7, and 32 that are necessary at the time of sewing without stopping the sewing device M, there is an effect that productivity can be improved.

  Further, in the above case, the type identification information and individual identification information relating to the attachment parts 6, 7, 32 in the sewing apparatus M used this time are written in the wireless tag T1 together with the sewing condition information in step S190 of the flow of FIG. You may do it. As a result, another sewing manufacturer who has read the information from the wireless tag T1 thereafter is necessary to realize a satisfactory sewing perfection level equivalent to the sewing product C sewn by the sewing apparatus M this time. The attachment parts 6, 7, 32 can be reliably identified.

  Further, in the mounting parts 6, 7, and 32 in which the type identification information and the individual identification information are stored in the wireless tag T2, information (usage history, etc.) related to the use of each of the parts 6, 7, and 32 is managed. Is also possible. That is, the individual identification information of the corresponding parts 6, 7, and 32 stored in the wireless tag T2 is read by the reader / writer 50 when attached to the sewing device M side (or when approaching), and the parts 6, 7 are correspondingly read. , 32 information related to its use (related to being used) (= usage history information such as the number of times / time of use of the part in the sewing apparatus M, and the time when it was used) Each motor 20, 22, 28, 30, 35, information on the operating state of the servo solenoid 33, air cylinder 24, etc.) is written and stored in the wireless tag T2 by the reader / writer 50 (in this case, transmission of the high frequency circuit 51) The unit 53 writes information related to the fact that the attachment part is used in the apparatus main body, and writes and transmits information related to the attachment part to the wireless tag corresponding to the attachment part via wireless communication without contact. Constitute a). Or you may memorize | store in appropriate memory | storage means, such as RAM17C of the control apparatus 17, without writing in the radio | wireless tag T2 side. For example, in the case of usage history information, the mode of data at this time may be such that unit usage data is accumulated and accumulated, or usage time data may be updated each time.

  In this case, in step S50 of the flow of FIG. 9, the use history information is read in addition to the type identification information and individual identification information regarding the components 6, 7, and 32, and accumulation and updating are performed as described above. At that time, the control device 17 reaches the time condition in which the information related to the use is set in advance according to the information related to the use read from the wireless tag T2 via the tag reader / writer 50 (for example, the parts 6, 7, In the case where the service life is 32 or the like is near), a predetermined operation restriction may be applied to the sewing apparatus main body M1 in the same manner as the above-described steps S250 and S260 in FIG. Further, at that time, according to the use history information read from the wireless tag T2 by the tag reader / writer 50, the control device 17 displays a predetermined warning when, for example, the service life of the parts 6, 7, 32 is near. The display control signal may be generated and output to the operation panel 15.

  In the modification using the information related to the above-mentioned use, the control device 17 (particularly, the procedure from step S250 in FIG. 9 to step S130 to step S130) places a predetermined limit on the operation of the apparatus main body. Second limit signal generating means for generating a signal to be added is configured. Also, the usage information reading means for reading the usage information related to the usage history of the corresponding mounting component from the wireless tag provided so that the receiving unit 54 of the high frequency circuit 51 of the tag reader / writer 50 is handled in association with the mounting component. Configure.

  In this modification, by storing information related to the use of each of the parts 6, 7, and 32, the quality life (particularly durability) of each of the parts 6, 7, and 32 of the same type according to the use situation Can be managed individually and appropriately to prevent a decrease in durability. Further, when the quality life of the parts 6, 7, and 32 is close according to use, the operator can appropriately recognize this by performing a predetermined warning display on the operation panel. As a result, since the parts 6, 7, and 32 can be quickly replaced before the durability is lowered, it is possible to prevent the sewing work efficiency from being lowered.

  Further, for example, in the case of the attachment parts 6, 7, and 32 that have reached (or approached) the service life, such a part having difficulty in durability is used by adding the predetermined operation restriction set in advance. However, the sewing apparatus M does not become inoperable, and the minimum necessary apparatus performance can be ensured without causing a failure due to a decrease in durability. In particular, when performing the above-described operation restriction, before adding the operation restriction, in step S250, a display prompting for confirmation of whether or not the operation restriction may be added is performed. It is possible to make the operator surely recognize in advance that it will be difficult to achieve the above performance. As a result, unreasonable use using the parts 6, 7, and 32 in an unfavorable state that causes a failure due to poor sewing or a decrease in durability is avoided as much as possible, thereby preventing a reduction in sewing work efficiency. be able to.

  In the above-described embodiment, the combination of the parts 6, 7, and 32 is not appropriate and the above-described operation restriction is performed, and in the modified example for managing the above-described usage information, the usage history of the parts 6, 7, and 32 is used. For example, the control device 17 may control the device main body M1 (specifically, for example, each of the motors 20, 22, 28, 30, 35, the servo solenoid 33, and the air cylinder 24). A signal for prohibiting the start of operation of the actuator) is generated and output to each, or a signal for decreasing the sewing speed or lowering the upper limit of the sewing speed is generated and output to the sewing machine motor 20. Conceivable. In the former case, for example, genuine parts or pirated attachment parts 6, 7, 32 that are not supposed to be attached in advance, or, for example, attachment parts 6, 7, 32 that have reached (or approached) their service life have been used. In addition, by preventing the apparatus main body M1 from operating, it is possible to reliably prevent the occurrence of malfunctions and failures.

  In the above description, when the operation restriction is performed on the sewing apparatus M side, in step S250, the operator is prompted to confirm whether or not the operation restriction can be performed. However, the present invention is not limited thereto. . In other words, the operation restriction is executed without performing confirmation input, and a display / alarm means (including a light, a lamp, etc.) provided separately is simply displayed that the predetermined operation restriction is added before the execution. Alternatively, the display may be performed before the execution, or may be displayed after the execution while the operation is restricted. Further, the display is not limited to display on the display unit 15A, and other warnings such as a buzzer or other sound warning means may be performed instead.

  Furthermore, in the above embodiment, the IC circuit unit 100 of the wireless tag T1 stores only the sewing condition information that was previously sewn by another sewing device M. However, the present invention is not limited to this. The type identification information and individual identification information of the sewing product C or sewing thread t used for sewing may be stored and read by the tag reader / writer 50 (in this case, the high-frequency circuit 51 of the tag reader / writer 50 may be read). Sewing information in which the receiving unit 54 reads the type identification information or individual identification information of the corresponding sewing material or sewing material from a wireless tag provided so as to be handled in association with the sewing material or sewing material as a workpiece. Configure the reading means). In the same manner as described above, the control device 17 determines whether or not the read identification information or individual information corresponds to what is assumed in advance as a target to be used at the time of sewing. Operation restriction may be performed. For example, the control device 17 generates a signal that prohibits the start of operation of the device main body M1 (specifically, for example, the motors 20, 22, 28, 30, 35, each actuator of the servo solenoid 33 and the air cylinder 24). It is conceivable to output each of them, or to generate a signal for lowering the sewing speed or lowering the upper limit of the sewing speed and output it to the sewing machine motor 20. In this case, if the type identification information or the individual identification information read by the sewing information reading means does not correspond to what is preliminarily assumed as a target to be used at the time of sewing, the control device 17 reduces the sewing speed of the apparatus main body. Alternatively, third limit signal generating means for generating a signal for reducing the upper limit of the sewing speed is configured.

  In this modified example, a sewing object or a use object at the time of sewing is generated by generating and outputting a signal or the like for reducing the sewing speed of the sewing apparatus body M1 or reducing the upper limit of the sewing speed as described above. Even if a sewing product C or a sewing thread t that is not assumed in advance (for example, inferior goods or deteriorated goods) is used, the sewing device M will not be sewn and failure due to a decrease in durability, etc. There is an effect that the minimum sewing performance can be ensured while preventing the occurrence of the above.

  Furthermore, in the above description, the wireless tags T2 are provided on the attachment parts 6, 7, and 32, and the respective attachment parts 6, 7, and 32 are identified (detected) by reading the wireless tag information. However, the present invention is not limited to this. . That is, other detection means, for example, a method in which normal barcode information is attached to each of the attachment parts 6, 7, and 32 and read by a barcode reader may be used. Alternatively, as long as the effect that the other person can easily and accurately understand the nature of the sewing product C sewn by the sewing manufacturer and the corresponding sewing conditions, which is the original effect of the present invention, is obtained. The detecting means for the mounting parts 6, 7, 32 is not always necessary.

  In the above description, the RAM 17C of the control device 17 is used as the storage means for storing the information related to the read machining conditions. However, the present invention is not limited to this, and EEPEOM, which is a nonvolatile storage means, may be used. However, as long as the effect that the other person easily and accurately understands the nature of the sewing product C sewn by the sewing manufacturer and the corresponding sewing conditions as a set, which is the original effect of the present invention, is obtained. The storage means for storing information relating to such sewing conditions is not necessarily required.

  Furthermore, in the above description, the case where the present invention is applied to the sewing apparatus M including the tag reader / writer 50 has been described as an example, but the present invention is not limited thereto. That is, a plurality of sewing devices M ′ not provided with a tag reader / writer (not shown, the same configuration as the sewing device M except for the tag reader / writer 50), and machining information writing separately from these sewing devices M ′ are written. (For example, one) tag reader / writer 50 '(= the same configuration as the tag reader / writer 50) and the control device 17 of each sewing device M' to exchange information and perform overall control of these sewing devices M ' A central control device 200 (not shown) as a host computer of a so-called sewing system that performs a display and a display device 210 (not shown) that performs various displays in response to input signals. For example, a sewing device provided in a sewing factory The present invention may be applied to an information communication system. In this case, the data reading / writing function of the tag reader / writer 50 in the above embodiment is executed by the tag reader / writer 50 ′ separate from the sewing apparatus M ′, and various display functions of the display unit 15A of the operation panel 15 are performed. The display device 210 is executed separately from the sewing device M ′.

  Also by this modification, the effect similar to the said embodiment is acquired. That is, when a sewing manufacturer starts sewing work on the workpiece C using a corresponding sewing device M ′ and completes sewing, the sewing device M is installed separately from the sewing device M ′ according to a manual operation input from the operation panel 15. The tag reader / writer 50 'writes each set value information relating to the sewing conditions at that time to the wireless tag T1 attached to the workpiece C sewn by the sewing apparatus M'. As a result, when another person subsequently obtains the sewing product C to which the wireless tag T1 is attached, not only the property of the sewing product C can be observed in the field, but also the RFID tag T1 can be obtained by the tag reader / writer 50 '. By reading the read sewing conditions into the sewing device M ′ corresponding to the above-mentioned other person, the other person knows in detail what kind of sewing condition the workpiece C having the property is sewn on. be able to. That is, another person can easily and accurately understand the property of the sewing product C sewn by the sewing manufacturer and the sewing conditions corresponding thereto. Other than the above, the functions of the tag reader / writer 50 are replaced with the tag reader / writer 50 ', and the functions of the operation panel display unit 15A are replaced with the display device 210 (various displays, alarms, etc. are notified). The same effect as the form can be obtained.

  In the above description, the present invention is applied to a so-called eyelet hole sewing machine (for example, Japanese Patent No. 2762696 by the applicant of the present application), but the application target of the present invention is not limited to this.
