Description

  The present invention relates to a splicing unit including a splicing device that performs a splicing operation on a carrier tape that supplies an electronic component to an electronic component mounting machine, and an electronic component supply system that replenishes the electronic component using the splicing unit.

  Electronic component mounting lines that use multiple electronic component mounting machines to produce substrates use many different types of electronic components, so there may be a storage location (such as a storage) for storing replenished electronic components. . In this storage place, a reel around which a carrier tape containing electronic components is wound, a tape feeder loaded with a reel, and the like are stored.

  Patent Document 1 describes an electronic component supply system that notifies information on electronic components to be prepared toward a storage location side terminal installed in a storage location when a component shortage is expected in an electronic component mounting machine. Yes. In this electronic component supply system, the mounting machine side terminal connected to the electronic component mounting machine calculates the number of parts used from the data sent from the electronic component mounting machine during the mounting operation as needed, and the parts are expected to run out. The preparation data of the electronic component to be generated is generated. The mounting machine side terminal transmits the generated preparation data to the storage location side terminal.

  The storage location side terminal displays the part name and quantity of the electronic parts to be prepared on the display unit based on the preparation data received from the mounting machine side terminal. The operator can grasp the type and number of reels to be prepared by confirming the display on the storage location side terminal. The operator transports the prepared reel or the like to a reel receiving place (such as a reel storage place installed on the production line) or to an electronic component mounting machine where parts are expected to run out. In the electronic component replenishment operation, the operator performs, for example, a splicing operation between the end of the carrier tape that is likely to run out of components and the start end of the carrier tape wound around the replenishment reel that has been brought.

  By the way, in the production site, from the viewpoint of work efficiency and the like, there are cases where each worker performs a plurality of work such as work for preparing a reel to be replenished and splicing work. In this case, for example, an operator who is in charge of transporting the supply reel forgets to carry out other urgent work, for example, even though the reel is prepared according to the instruction of the storage location terminal. There is a fear.

  When such a human error occurs, the worker in charge of splicing, for example, is in a state where the replenishment reel does not arrive by the timing at which it is desired to use it. Alternatively, the worker in charge of splicing may go to pick up the reel that has been replenished to the reel receiving location in anticipation of the progress of the work, but notice that the reel that was expected at the reel receiving location has not been replenished. Become.

  Further, for example, consider a case where a worker at a storage location prepares a supply reel in accordance with an instruction from a storage location terminal at a production site where a reel receiving location is provided at the storage location. In this case, the worker in charge of splicing considers changing the supply reel to be used in accordance with the progress of the work, and takes the desired supply reel to the reel receiving place (storage place). However, since the workers at the storage location prepare in order according to the instructions of the storage location terminal, it becomes difficult for the worker in charge of splicing to receive the desired supply reel immediately. As a result, there is a risk that the production efficiency may be reduced due to the delay in the replenishment of electronic components and the production line being stopped due to the lack of components.

  The present invention has been made in view of the above problems, and a splicing unit that can appropriately prepare a supply reel and improve production efficiency, and an electronic component that replenishes an electronic component using the splicing unit The purpose is to provide a supply system.

  The splicing unit according to claim 1 is a splicing device that performs a splicing operation of a carrier tape of a reel loaded in the tape feeder and a carrier tape of a supply reel on a tape feeder mounted on an electronic component mounting machine. A reception unit that receives information specifying the supply reel that is a target of a preparation request at a storage location for storing a plurality of supply reels, and communicates with a storage location side device installed at the storage location And a processing unit that transmits information specifying the supply reel received by the reception unit to the storage location side device via the communication unit, and requests preparation of the supply reel. And comprising.

  An electronic component supply system according to a fifth aspect includes a splicing unit according to any one of the first to fourth embodiments, the electronic component mounting machine, the splicing unit, and the storage location side performing communication via the communication unit. An apparatus.

  According to the configurations of the inventions according to claims 1 and 5, the operator on the splicing unit side, for example, when the desired supply reel is not supplied to the reel receiving place or when the supply reel to be used is changed. The information specifying the supply reel that the worker in the storage location wants to prepare is input by operating the reception unit. The processing unit transmits information specifying the supply reel received by the receiving unit to the storage location side device via the communication unit. The worker on the storage location side, for example, notices that he has forgotten to carry the supply reel from the storage location to the reel receiving location on the production line by checking the display on the storage location side device. The worker on the storage site side can take appropriate measures such as transporting the supply reel to the reel receiving location again. Alternatively, the worker at the storage location can know the supply reel that the worker on the splicing unit side wants to use immediately. The worker at the storage location can preferentially prepare the supply reel requested for preparation. The worker on the splicing unit side, for example, issues a preparation request by the processing unit, and then moves to a reel receiving place on the production line or a reel receiving place on the storage place in time. The worker on the splicing unit side obtains the reel supplied to the reel receiving place, carries it to the electronic component mounting machine, and supplies the component by the splicing device. Accordingly, by appropriately preparing the supply reel, it is possible to supply the parts before the production line stops and the production line is stopped, and the production efficiency can be improved.

The reel holder 46 is a storage box for storing the reel 32 that is out of parts removed from the tape feeder 30 during the splicing operation. The dust box 47 is for discarding a piece (waste tape) or the like of the carrier tape 31 generated in splicing work.

  In addition, a columnar column 48 is provided on the base table 44. The column part 48 is fixed in a state where it is erected along a direction perpendicular to the plane of the base table 44. A main body portion 42 is attached to the upper portion of the column portion 48. The main body 42 includes a splicing device 50, a reel bucket 51, a barcode reader 52, a communication unit 54 (see FIG. 7), and a display device 55. In addition, the main body 42 includes a main body processing unit 42 </ b> C including a CPU and various memories as a processing unit that controls each of the above devices. In the following description, as shown in FIGS. 4 and 7, the reel 32 stored in the reel bucket 51 and the reel 32 stored in the storage 8 are distinguished from the reel 32 loaded in the tape feeder 30. Therefore, the supply reel 56 will be described.

  The splicing device 50 is a device that automatically joins the end of the carrier tape 31 wound around the reel 32 loaded in the tape feeder 30 to the start end of the carrier tape 31 wound around the supply reel 56. The splicing device 50 has a substantially rectangular parallelepiped shape that is long in one direction. The reel bucket 51 is provided on one side (the back side in FIG. 4) of the side surface facing in the longitudinal direction of the splicing device 50 and at a position close to the side surface. The reel bucket 51 can accommodate a plurality of supply reels 56. The worker obtains a new supply reel 56 and stores it in the reel bucket 51 in, for example, the storage 8 or the reel storage place 9 (see FIG. 1) of the production lines 2A and 2B.

  Further, the splicing device 50 includes a feed groove 50A (only the feed groove on the near side is shown in FIG. 4) on each of the side surfaces opposed in the longitudinal direction. The feed groove 50A is a groove for inserting the two carrier tapes 31 to be spliced up to the center of the splicing device 50. At the center of the splicing device 50, there is provided a joining device (not shown) for attaching the splicing tape to the two carrier tapes 31 fed along the feed groove 50A and joining the two. When the two carrier tapes 31 are fed into the respective feed grooves 50A by the operator, the splicing device 50 cuts unnecessary portions of the two carrier tapes 31 with a cutting device (not shown) and abuts each other's cut surfaces. Both carrier tapes 31 are joined by a joining device. When the splicing operation is completed, the splicing device 50 opens the upper cover 50B so that the carrier tape 31 that has been spliced can be taken out.

  The barcode reader 52 is, for example, a cordless handy type that performs wireless communication with the main body processing unit 42 </ b> C of the main body 42. The work table 42D of the main body 42 is provided with an engaging portion 42E for hooking the barcode reader 52. The operator removes the barcode reader 52 from the engaging portion 42E and holds it in his / her hand to read the barcode 38 of the reel 32 removed from the tape feeder 30 or the barcode 38 of the supply reel 56 taken out from the reel bucket 51. I do. As a result, the main body processing unit 42C executes so-called splicing verification, which checks whether or not the carrier tape 31 (replenishment reel 56) containing correct electronic components has been prepared in the splicing operation.

  For example, when the barcode 38 of the old reel 32 that is out of parts is read by the barcode reader 52, the main body processing unit 42C starts splicing verification, and the information on the barcode 38 of the reel 32 is transmitted to the communication unit 54 (see FIG. 7). ) To the host computer 3. The communication unit 54 can communicate with the host computer 3 through a wireless LAN through an access point provided in the communication network 7, for example.

  Next, when the barcode 38 of the supply reel 56 is read by the barcode reader 52, the main body processing unit 42C transmits information on the barcode 38 of the supply reel 56 to the host computer 3. In the management data D2 stored in the storage device 3A of the host computer 3, information on the barcode 38 and data on the component code are stored. Based on the information on the barcode 38 received from the main body processing unit 42C (splicing unit 5), the host computer 3 determines whether or not the component code of the electronic component for which the splicing operation is to be performed is matched.

  When the host computer 3 determines that the collation of the electronic components is good, the host computer 3 notifies the main body processing unit 42C that it is good. The main body processing unit 42C automatically starts the splicing work by the splicing device 50 when it is received that it is good. Further, the host computer 3 notifies the main body processing unit 42C of a collation error when the component codes of the electronic components do not match. When the main body processing unit 42C receives a confirmation error from the host computer 3, the main body processing unit 42C displays the fact on the display device 55 and stops the splicing operation. In this way, the splicing unit 5 (main body processing unit 42C) can prevent spurious splicing of the wrong carrier tape 31 such as a different type of electronic component by the process linked to the host computer 3. ing.

  The display device 55 includes a touch panel 55A having a display function and an input function. FIG. 5 shows an example of a display screen when the touch panel 55A is viewed from the front. An information display section 55B for displaying information such as the above-described collation error and the number of the barcode 38 read by the barcode reader 52 is provided at the center of the touch panel 55A. In addition, a radio wave intensity display unit 55C that displays the intensity of the received radio wave received from the access point by the communication unit 54 is provided at the upper right of the touch panel 55A. A cancel button 55D is provided below the information display portion 55B. The cancel button 55D notifies the main body processing unit 42C of a stop instruction, for example, when it is desired to stop the process during the above-described splicing verification.

  In addition, on the left side of the information display portion 55B, a notice display portion 55E that indicates a notice of the tape feeder 30 that is expected to run out of parts is provided. The touch panel 55A of the present embodiment is provided with five notice display sections 55E. The notice display section 55E displays information of the tape feeder 30 to be replenished, that is, the expected component cut-off received from the host computer 3 is displayed. For example, in the top notice display section 55E, the module number “2” for identifying the electronic component mounting machine 13, the slot numbers “4” of the slots S1 to Sn of the tape feeder 30 to be replenished, and the component has run out. An expected time “00:03:30” until the occurrence is displayed. In this case, the advance notice display section 55E displays that the part out of the tape feeder 30 attached to the slot number “4” of the module number “2” occurs after 3 minutes and 30 seconds. The module numbers are set in the order of 1, 2, 3,... From the upstream side to the downstream side of the production line 2A for the plurality of electronic component mounting machines 13, for example. The above-described method of indicating the position of the tape feeder 30 to be replenished by the notice display unit 55E is an example. For example, the overall configuration of the production line 2A is schematically illustrated, and the tape feeder to be replenished is illustrated on the schematic diagram. 30 positions may be displayed.

  The main body processing unit 42C of the main body unit 42 acquires, for example, information on the tape feeder 30 that is expected to be out of parts from the host computer 3 for 10 cases. The main body processing unit 42C periodically executes the process to be acquired. The main body processing unit 42C displays, on the notice display unit 55E, five items of the acquired ten pieces of information that have a short estimated time until a component shortage occurs. In addition, the main body processing unit 42C causes the notice display unit 55E to display the five items to be displayed from the top to the bottom of the screen in order from the shorter expected time. Therefore, as shown in FIG. 5, the expected time displayed on the notice display unit 55E increases in order from the top to the bottom of the screen. Note that the main body processing unit 42C, for example, opens the upper cover 50B after the above-described splicing operation is completed, confirms the spliced tape by the operator, and then closes the upper cover 50B, and displays a notice display unit that has completed the splicing operation. It is preferable to erase 55E from the display on the touch panel 55A.

  Further, when the main body processing unit 42C receives the information of the tape feeder 30 expected to be out of parts from the host computer 3, the main body processing unit 42C detects the part code of the electronic part to be supplied to the tape feeder 30 that is expected to be out of parts and the part out A combination with the module number (slot number) in which the expected tape feeder 30 is mounted is displayed on the information display section 55B. Thus, the worker can determine which part code of the electronic component (replenishment reel 56) should be spliced to the tape feeder 30 (module number or slot number) of which notice display portion 55E. Further, for example, when the worker moves to the reel storage place 9, whether or not there is a supply reel 56 that needs to be taken out from the reel storage place 9 by checking the component code displayed on the information display portion 55 </ b> B. Can be judged.

(4. Preparation request processing)
Next, a preparation request process for requesting preparation of the supply reel 56 from the splicing unit 5 to the storage location side device 4 will be described. FIG. 6 shows a flowchart of the preparation request process executed by the main body processing unit 42 </ b> C of the splicing unit 5. FIG. 7 shows a control flow in the preparation request process. A worker A who uses the splicing unit 5 is assigned to the production line 2A shown in FIG. In addition, the worker B who prepares the supply reel 56 is assigned to the storage 8 as a charge. The production line 2 </ b> A is provided with a reel storage place 9 for placing a supply reel 56 taken out from the storage 8 by the worker B. The storage 8 is provided with a reel receiving stand 8A as a reel receiving place for delivering the supply reel 56 when the worker A directly takes the supply reel 56 to the storage 8.

  The main body processing unit 42C of the splicing unit 5 according to the present embodiment, when the operator A touches the preview display unit 55E of the touch panel 55A, requests for preparation of the supply reel 56 corresponding to the preview display unit 55E that has been touched. To the storage location side device 4. Specifically, when the preparation request process is started, the main body processing unit 42C determines whether or not a touch operation has been performed on the notice display unit 55E in a step 11 (hereinafter simply referred to as “S”) 11 illustrated in FIG. To do.

  Note that the main body processing unit 42C executes, for example, the preparation request process illustrated in FIG. 6 in parallel for each notice display unit 55E. Therefore, the main body processing unit 42C monitors whether or not each notice display unit 55E has been touched by a separate process. For example, when a touch operation is performed on a plurality of the notice display units 55E, the main body processing unit 42C executes the preparation request process shown in FIG. . Further, the main body processing unit 42C starts the preparation request process shown in FIG. 6, for example, when the power switch 42B (see FIG. 4) is turned on and activated. In this case, the main body processing unit 42C always accepts a touch operation on the notice display unit 55E in a state where the operation on the notice display unit 55E is possible. Alternatively, the main body processing unit 42C may start the preparation request process after, for example, operating the touch panel 55A to change to a specific mode. In this case, the main body processing unit 42C may prohibit or disable the touch operation on the notice display unit 55E until the mode is changed to a specific mode.

  In S11, when the main body processing unit 42C determines that there is no touch operation on the notice display unit 55E (S11: NO), the main body processing unit 42C executes the determination process of S11 every predetermined time until there is a touch operation on the notice display unit 55E. Accordingly, the main body processing unit 42C repeatedly executes the determination process of S11 until a touch operation is performed on any of the five notice display units 55E (see FIG. 5) being displayed on the touch panel 55A.

  On the other hand, when a touch operation is performed on any one of the five notice display parts 55E among the five notice display parts 55E, the touch panel 55A receives the input information D3 that specifies the notice display part 55E that has been touched as a main body processing part 42C. (See FIG. 7). For example, the worker A of the production line 2A moves to the reel storage place 9 and searches for the supply reel 56 having the same part code while checking the display content of the information display section 55B of the touch panel 55A. When the desired supply reel 56 has not been prepared in the reel storage place 9, the worker A makes a preparation request by touching the notice display portion 55E. Alternatively, when the worker A wants to change the supply reel 56 to be used in accordance with the progress of various operations, the operator A makes a preparation request by touching the notice display portion 55E, up to the reel receiving stand 8A of the storage 8. Go to pick up the desired supply reel 56. In FIG. 7, two reel receiving places, a reel receiving stand 8 </ b> A and a reel storage place 9, are installed, but the workers A and B indicate the reel receiving place for receiving the supply reel 56 requested for preparation. It is preferable that the reel receiving base 8A or the reel storage place 9 is determined in advance. Alternatively, the main body processing unit 42C may be configured to transmit information to the storage location side device 4 including information specifying the reel receiving location.

  As shown in FIG. 8, for example, the operator performs a touch operation on the third notice display unit 55E from the top on the touch panel 55A. Based on the input information D3 input from the touch panel 55A, the main body processing unit 42C detects that the touch operation has been performed and the notice display unit 55E that has been touched (S11: YES). The main body processing unit 42C sends the preparation request data D4 for requesting the supply reel 56 that can be spliced to the tape feeder 30 mounted at the position of the module number and slot number of the notice display unit 55E that has been touched, to the communication unit 54. To the host computer 3 (S12). For example, the main body processing unit 42C transmits the module number and slot number of the selected notice display unit 55E to the host computer 3 as the preparation request data D4. When a plurality of splicing units 5 are provided in the production line 2A, the splicing unit 5 transmits the identification request information for identifying the preparation request data D4 from the other splicing units 5 by itself. It is preferable to add to D4.

  For example, when the host computer 3 receives the preparation request data D4, the host computer 3 refers to the management data D2 and searches for a part code that matches the requested supply reel 56. The management data D2 includes the module number of the electronic component mounting machine 13, the slot number of the electronic component mounting machine 13, the feeder ID 39 of the tape feeder 30 mounted in the slot, the barcode 38 of the reel 32 loaded in the feeder ID 39, the reel Data in which the component codes of the electronic components of the carrier tape 31 wound around 32 are associated with each other is stored. Therefore, the host computer 3 can search the management data D2 for the slot number and the like of the preparation request data D4 and determine a component code that is suitable as the supply reel 56. For example, the host computer 3 transmits preparation request data D4 to which the determined compatible part code is added in addition to the module number and the like to the storage location side device 4.

  The part code may be determined by the splicing unit 5 or the storage location side device 4. For example, the main body processing unit 42C of the splicing unit 5 may acquire the management data D2 from the host computer 3 and determine the part code. In this case, the host computer 3 may transfer the preparation request data D4 received from the splicing unit 5 to the storage location side device 4 as it is because search processing for the management data D2 is unnecessary. Further, the host computer 3 may use, for example, the barcode 38 of the supply reel 56 instead of using the component code as information for specifying the supply reel 56 to be prepared.

  Next, after sending the preparation request data D4 to the host computer 3 (storage location side device 4), the main body processing unit 42C changes the display of the notice display unit 55E that has requested the preparation (S13). For example, like the part indicated by hatching in FIG. 9, the main body processing unit 42C changes the color of the notice display unit 55E requested for preparation (touched) to a conspicuous color such as yellow. Thereby, the worker A can confirm that the preparation request has been made to the storage location side device 4 by seeing the change in the display of the notice display section 55E. The main body processing unit 42C may change the display before the preparation request data D4 is transmitted, for example, when the notice display unit 55E is selected.

  Next, the main body processing unit 42C determines whether or not a response (payout information D5) to the preparation request has been received from the storage location side device 4 (S14). The main body processing unit 42C repeatedly executes the determination process of S14 every predetermined time until a response is received from the storage location side device 4 (S14: NO).

  The storage location side device 4 displays the information of the preparation request data D4 received from the host computer 3. FIG. 10 shows an example of the display screen of the display unit 4 </ b> B of the storage location side device 4. As shown in FIG. 10, on the display unit 4B, for example, the fact that the preparation request has been received, the identification information of the splicing unit 5, the module number, the slot number, the part code, the received time, and the like are displayed. Thereby, the worker B of the storage 8 can check the part code of the supply reel 56 requested for preparation and the splicing unit 5 requested for the preparation by looking at the display of the storage location side device 4. . Further, the worker B can know the number of the production line 2A that requires the supply reel 56 by confirming the displayed module number and slot number. Further, for example, although the worker B prepares the supply reel 56 in accordance with the display on the storage location side device 4, the worker B carries it out to the reel receiving stand 8 </ b> A or the reel storage place 9 due to interruption of other urgent work. If you forget, you can realize that you forgot. In addition, the worker B can prepare the supply reel 56 that has received the preparation request with priority over other operations.

  The worker B searches for and prepares the supply reel 56 that has received the preparation request from the storage 8. The worker B uses the storage location side device 4 to carry out the processing for taking out the found supply reel 56 from the storage 8. For example, the worker B selects the prepared preparation request data D4 from the plurality of preparation request data D4 displayed on the storage location side device 4. The worker B reads the barcode 38 of the supply reel 56 to be taken out by the barcode reader 4A with the preparation request data D4 selected. As a result, the storage location side device 4 can determine whether or not the part code of the preparation request data D4 selected on the display screen matches the part code of the supply reel 56 from which the barcode 38 has been read. For example, the storage location side device 4 acquires management data D <b> 2 from the host computer 3 to determine whether the part codes match.

  When the part code does not match, the storage location side device 4 displays a warning or the like and notifies the operator B that the codes do not match. Further, when the part codes match, the storage location side device 4 displays a message indicating that they match, and transmits payout information D5 indicating that the supply reel 56 is taken out to the host computer 3 (see FIG. 7). When the host computer 3 receives the payout information D <b> 5 from the storage location side device 4, the host computer 3 updates the information of the management data D <b> 2 regarding the supply reel 56 taken out from the storage 8. Further, the host computer 3 returns the payout information D5 to the splicing unit 5 that has transmitted the preparation request data D4 in S12 described above.

  On the other hand, when the worker B of the storage 8 confirms that the part codes of the supply reel 56 taken out by the storage location side device 4 match, the prepared supply reel 56 is transferred to a predetermined reel receiving location (reel). To the receiving stand 8A and the reel storage 9). As a result, the supply reel 56 requested for preparation from the splicing unit 5 is arranged at the reel receiving place.

  When the main body processing unit 42C of the splicing unit 5 receives the payout information D5 from the host computer 3 via the communication unit 54 (S14: YES), the notice display unit 55E whose display has been changed in S13 described above, that is, preparation A process of returning the display of the requesting notice display section 55E (see FIG. 9) to the original display screen shown in FIG. 8 is executed (S15). Thereby, the operator A of the splicing unit 5 can confirm that the replenishment reel 56 requested for preparation is to be taken out from the storage 8 and placed in a predetermined reel storage area. The operator A can receive the supply reel 56 requested for preparation more reliably by moving to the reel storage place 9 of the production line 2A in accordance with the timing after the display is changed. The main body processing unit 42C restores the display of the notice display unit 55E, and then ends the preparation request process illustrated in FIG.

(5. Effects of the configuration of the embodiment)
In the electronic component supply system 1 of the above-described embodiment, with respect to the tape feeder 30 mounted on the electronic component mounting machine 13, the carrier tape 31 of the reel 32 loaded in the tape feeder 30 and the carrier tape 31 of the supply reel 56. Preparation request data D4 (information) for identifying the replenishment reel 56 that is the target of the preparation request in the splicing device 50 that executes the splicing operation and the storage 8 (storage location) that stores the plurality of supply reels 56 Touch panel 55A (accepting unit) that receives the information from the worker A, the communication unit 54 that communicates with the storage location side device 4 installed in the storage 8, and the preparation request data that specifies the supply reel 56 received by the touch panel 55A D4 is transmitted to the storage location side device 4 via the communication unit 54, and a book requesting the preparation of the supply reel 56 It includes a processing unit 42C (unit), a.

  According to this, the worker A on the splicing unit 5 side, for example, when the desired supply reel 56 is not supplied to the reel storage 9 or when the supply reel 56 to be used is desired to be changed, etc. The operator B inputs preparation request data D4 for specifying a supply reel 56 to be prepared by operating the touch panel 55A. The main body processing unit 42C transmits information (preparation request data D4) specifying the supply reel 56 received by the touch panel 55A to the storage location side device 4 via the communication unit 54. For example, the worker B of the storage 8 recognizes that he has forgotten to carry the supply reel 56 from the storage 8 to the reel storage place 9 of the production line 2A by checking the display of the storage location side device 4. Become. The worker B can take appropriate measures such as transporting the supply reel 56 to the reel storage place 9 again. Alternatively, the worker B of the storage 8 can know the supply reel 56 that the worker A on the splicing unit 5 side wants to use immediately. The worker B can preferentially prepare the supply reel 56 requested for preparation. For example, the worker A of the splicing unit 5 makes a preparation request by using the splicing unit 5 (main body processing unit 42C), and then moves to the reel storage 9 or the reel receiving stand 8A at an appropriate timing. The worker A obtains the supply reel 56 supplied to the reel storage 9 and the like, carries it to the electronic component mounting machine 13, and supplies the components by the splicing device 50. Thus, by appropriately preparing the supply reel 56, the parts can be supplied before the production line 2A is stopped due to running out of parts, and the production efficiency can be improved.

  Further, the splicing unit 5 further includes a display device 55 (display unit) that displays a slot number for mounting the tape feeder 30 on the electronic component mounting machine 13 and that needs to be replenished by splicing work. The touch panel 55A (accepting unit) specifies information (preparation request data D4) for identifying the supply reel 56 with the selected slot number in response to selection of one of the slot numbers displayed on the display device 55. ).

  According to this, the worker A on the splicing unit 5 side compares the slot number displayed on the display device 55 with the slot number written on the electronic component mounting machine 13 and the tape to be spliced. The position of the feeder 30 can be confirmed. At this time, when there is no electronic component supply reel 56 to be used for the splicing work, the worker A selects the slot number of the display device 55 to prepare for specifying the supply reel 56 to be prepared. The request data D4 (for example, the component code of the electronic component supplied from the tape feeder 30 attached to the slot number or the slot number) can be notified to the storage location side device 4. Accordingly, the worker A of the splicing unit 5 can easily make a preparation request by selecting a slot number without inputting the preparation request data D4 (part code or the like) specifying the supply reel 56 to be prepared. Can do.

  Furthermore, the main body processing unit 42C (processing unit) displays the display device 55 (in response to receiving information (preparation request data D4) for specifying the supply reel 56 by the touch panel 55A (receiving unit) when the slot number is selected. The display of the selected slot number (notice display section 55E) on the display section) is changed.

  According to this, the worker A on the splicing unit 5 side sees that the display of the slot number has been changed, and has made a preparation request to the storage location side device 4, and has made a preparation request. Slot number (part code of the supply reel 56) can be confirmed.

  Furthermore, the main body processing unit 42C (processing unit) indicates that the preparation has been completed for the supply reel 56 that has requested preparation from the storage location side device 4 via the communication unit 54. It is displayed on the display device 55.

  According to this, after receiving the preparation request, for example, when the preparation of the requested electronic component supply reel 56 is completed, the worker B on the storage 8 side operates the storage location side device 4. Then, necessary work is carried out when taking out from the storage 8 to the reel storage 9 or the like. In response to this, the storage location side device 4 transmits a preparation completion notification (payout information D5) to the splicing unit 5. When receiving the payout information D5 from the storage location side device 4, the main body processing unit 42C of the splicing unit 5 changes the display of the notice display unit 55E. The worker A on the splicing unit 5 side notices the change in the display on the notice display unit 55E, and can confirm the timing when the worker B on the storage 8 side prepares and carries the reel storage 9 or the like. As a result, the worker A on the splicing unit 5 side, for example, moves to the reel storage 9 after displaying the completion on the notice display section 55E, so that the supply requested for preparation when he arrives at the reel storage 9 The reel 56 for use can be obtained more reliably.
