Detailed ways

The embodiments of the present application are described below through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments may be combined with each other under the condition of no conflict.

It should be noted that the drawings provided in the following embodiments are only used to illustrate the basic concept of the present application in a schematic way, so the drawings only show the components related to the present application rather than the number, shape and number of components in actual implementation. For dimension drawing, the type, quantity and proportion of each component can be changed at will in actual implementation, and the component layout may also be more complicated.

As shown in FIG. 1 , a schematic flowchart of a label clipping control method in an embodiment of the present application is shown. Applied to a label cutting control system including a sensor, a label cutting device, and a conveying motor, as shown in the figure, the method includes:

Step S1: Presetting an initial label feeding length instruction according to the length of a single label.

In this embodiment, the label is usually cut according to the set cutting length or the label feeding length (ie the label length), but if there is an error between the set cutting length and the actual label length, such as 0.1mm When the number of labels is large, such as 100 labels, the accumulated error reaches 10mm, which has a serious impact on the cutting effect. In this application, the initial length of the bid is preset according to the length of a single label, because the bid has not yet started to be sent, and there is no data of the actual length of the bid. During the bid submission process, correction or Adjustment. Therefore, according to the label length, it is initially set as the initial feed length command. Its purpose or use is different from existing methods.

In this embodiment, the acquisition of the length of the single label can be obtained by real measurement, or can be obtained by the product parameters of the label tape.

As shown in FIG. 2 , a schematic diagram of a label tape in an embodiment of the present application is shown. Labels are usually printed in batches. For labels with better quality, the printing quality is better, that is, the length of each printed label is uniform, and the marking line between the labels is obvious or there is no missing printing. However, for the label tape with poor printing quality, the printed label length may be irregular or defective, that is, the length of each actual label and whether the marking line is accurate or clear cannot be guaranteed.

Step S2: Send a corresponding number of pulses to the conveying motor according to the initial label feeding length command, so that it transmits the label tape containing multiple labels along the label feeding direction.

As shown in FIG. 3A , a scene schematic diagram showing the starting position of label feeding in an embodiment of the present application is shown. As shown in the figure, the scene includes a feeding table 1, a label cutting device 2, a marking line 3, a label tape 4 containing multiple labels, a sensor 5, and the label feeding direction is shown by the arrow in the figure. At this time, the state is that the starting end of the label tape 4 is aligned with the starting line corresponding to the label cutting device 2 .

In addition, L1 is the distance between the start line corresponding to the label cutting device 2 and the end line corresponding to the sensor 5 , and L2 is the length of a single label. L3 is the length of the solid color area before the marking line, and L4 is the length of the solid color area after the marking line.

In an embodiment of the present application, both sides of the marking line between two adjacent labels on the label tape respectively have solid color regions of a certain width. As shown in FIG. 3A , the solid color areas on both sides of the front marking line of the label corresponding to the sensor 5 are Amin-Amax, and the lengths of the corresponding front marking lines to Amin and Amax are L3 and L4 respectively; The solid color areas on both sides of the rear marking line of the label corresponding to the sensor 5 are Bmin-Bmax, and the lengths of the corresponding rear marking lines to Bmin and Bmax are L3 and L4 respectively.

As shown in FIG. 3B , a schematic diagram of a scenario where the label feeds the length of label L according to an embodiment of the present application is shown. As shown, the label is conveyed L length in the label feed direction.

In this embodiment, when the label feed starts, according to the initial label feed length command, a corresponding number of pulses are sent to the conveying motor to theoretically drive the label tape to transmit the corresponding initial label feed length command along the label feed direction. the length of the bid. At the beginning, the feed length here is based on the length of a single label, and after one cut, it is based on the feed length corresponding to the actual feed length command calculated subsequently.

Specifically, the transmission motor is a transmission motor, that is, it receives one pulse and advances once. After receiving the pulse, the conveying motor drives the roller, and the roller presses the label tape to realize the label delivery.

Step S3: When the sensor detects the marking line between two adjacent labels on the label tape, count the number of sent pulses to obtain the actual label feeding length and calculate the actual label feeding length command, so that the conveying motor will be When the label tape has transmitted the distance corresponding to the actual label feeding length command in the label feeding direction, it interrupts sending pulses to it.

In an embodiment of the present application, corresponding to FIG. 3B , the calculation method of the actual bidding length instruction is: L1-L2*N+L;

Wherein, the length L1 between the label cutting device and the sensor; the length L2 of the single label; the actual label feeding length L; Remove the remainder to get an integer.

Since the length of the label on the label tape is not fixed, the above method is used for calculation, so that labels of different sizes or styles can be applied without adjusting the distance of the sensor or the cutting position of the label, which greatly improves the applicability.

The number of sent pulses is counted to obtain the actual length of the bid delivery. For example, the relationship between the number of pulses received by the conveying motor and the distance it drives the label tape forward may be: for every 60 pulses sent, the conveying motor drives the label tape forward by 1mm.

The method for the sensor to detect the marking line between two adjacent labels on the label tape includes: when the sensor senses the solid color area, generating a falling edge; when the sensor senses the marking line, then Generate a rising edge.

It should be noted that usually most of the labels are patterns or texts. In the method described in this application, the main body of the label is not subjected to induction detection, and only a falling edge signal is generated when a solid color area is sensed, which is equivalent to telling the sensor to prepare When the marked line is sensed, let the sensor enter the ready-to-sensing, and when the marked line is sensed, a rising edge signal is generated to confirm that the marked line is detected, and then it will enter the solid color area, and the test sensor will generate a falling edge signal, which is equivalent to Tell the sensor that it is ready to rest. When it leaves the solid color area (that is, it senses the main pattern or text of the label), the sensor does not process. In this way, while saving resources, the accuracy of detecting the marking line is ensured.

Further, as shown in FIG. 3A , the reverse direction of the label feeding direction is preset as the X-axis direction, and the point where the end line corresponding to the sensor is mapped on the label tape when the conveying motor starts or is interrupted is: 0 coordinate; the coordinates of the solid color area on the front marking line and the rear marking line of the label corresponding to the 0 coordinate are respectively:

The coordinates of the solid color area before the front marking line: Amin=L2*N-L1-L3;

The coordinates of the solid color area behind the front marking line: Amax=L2*N-L1+L4;

The coordinates of the solid color area before the rear marking line: Bmin=L2*(N+1)-L1-L3;

The coordinates of the solid color area behind the marking line: Bmax=L2*(N+1)-L1+L4;

Wherein, L3 is the width distance in front of the marking line; L4 is the width distance behind the marking line; N=L1/L2, and N is taken as an integer according to the method of removing tails.

Step S4: when the transmission motor is interrupted, the label cutting device is ordered to cut the label tape, and at the same time, the number of sent pulses is cleared, and the actual label feeding length command is repeated as the initial label feeding length command. Steps S2-S3.

In this embodiment, this step has the function of connecting back and forth. On the one hand, it moves the corresponding distance to make the label cutting device cut, and on the other hand, clears the counted number of pulses, which is the sending of the next label. Process steps S2-S3 prepare.

first embodiment

For example, the present application is in an ideal case embodiment.

Assuming that the actual label length is 20mm, preset the following parameters: L1=45mm, L2=20mm, L3=3mm, L4=3mm; the relationship between the number of pulses received by the transmission motor and the distance it drives the label belt forward can be: every 60 A pulse, the transmission motor drives the label tape forward 1mm.

N=L1/L2 is calculated, and N is fetched to obtain an integer according to the tailing method, that is, N=2. Amin=L2*N-L1-L3 coordinate is -8, Amax=L2*N-L1+L4 coordinate is -2, Bmin=L2*(N+1)-L1-L3 coordinate is 12, Bmax=L2*( N+1)-L1+L4 coordinates are 18.

The initial position is shown in Figure 4A. Initially, the label transmission length command L5 is set to be consistent with the set length of a single label, that is, L5=L2=20mm, and the actual label transmission length L is 0mm:

The first process: In this process, a total of 720 pulses are sent to the conveying motor, and the label tape is sent forward by 12mm. The end line of sensor 5 is about to enter the interval between Bmin and Bmax. During this transmission process, the signal of sensor 5 is always considered invalid.

At the end of this process, the actual label delivery length L is 12mm, which is the same value as Bmin. The label transmission length command L5 is still 20mm, and the label position is shown in Figure 4B.

Second process: In this process, the end line of sensor 5 is in the interval between Bmin and Bmax, and the signal of sensor 5 is considered valid. Detect the signal of sensor 5 while sending pulses to the conveying motor. When the rising edge of the signal of sensor 5 is detected, that is, when the sensor detects the marking line of the label, ideally, a total of 180 pulses are sent to the conveying motor. Sent 3mm forward.

When the sensor detects the marking line of the label, the actual label transmission length L is 15mm. Since the rising edge of the sensor 5 signal is detected, the instruction to update the label transmission length is L5=L1-L2*N+L=45-20*2 +15=20mm.

When the sensor detects the marking line of the label, the label position is shown in Figure 4C.

Third process: In this process, the signal of the sensor 5 is considered invalid. When the actual label transmission length L value is the same as the updated actual label transmission length command L5=20mm, the process ends.

At the end of this process, no more pulses will be sent to the conveying motor, the conveying of the label will be stopped, and the cutting operation of the label will be realized. At this time, the position of the label is shown in Figure 4D.

After this process is over, this round of process will be repeated to realize the delivery and trimming of the next label.

It should be noted that, the method described in this application can realize accurate label trimming in addition to normal circumstances, and can also realize accurate label trimming for various special situations. A detailed description will be given below.

For some special cases, in an embodiment of the present application, the method for calculating the actual bid-delivery length instruction further includes:

Determine whether the 0 coordinate is within the range of Amin-Amax;

If it is within the range of Amin-Amax, when the sensor detects the marking line between two adjacent labels on the label tape, let the actual label feeding length command=L1-L2*(N-1)+L ;

If it is not within the range of Amin-Amax, then determine whether the 0 coordinate is within the range of Bmin-Bmax;

If it is within the range of Bmin-Bmax, when the sensor detects a marking line between two adjacent labels on the label tape, let the actual label feed length command=L1-L2*N+L.

In this embodiment, there are few cases in the range of Amin-Amax. For details, please refer to the fourth embodiment below.

In an embodiment of the present application, the method further includes: in a complete bid feeding process, if the marking line is not detected, continuing to send and cut the bid according to the instruction for setting the initial bid feeding length, and A fault will be prompted at the end of this clipping action. For example, a voice or text prompt is provided for the operator to review and decide whether to continue the label cutting operation.

Second Embodiment

Due to the printing length error of the label, measuring the length of the label will also cause measurement error and other factors, and there will be a slight deviation between the actual length of the label and the set length value. Such small deviations are magnified when hundreds of logos are transmitted.

For example, the actual label length is 20.1mm, and the following parameters are set in the system: L1=45mm, L2=20mm, L3=3mm, L4=3mm; the relationship between the number of pulses received by the transmission motor and the distance it drives the label belt forward can be as follows: : Every time 60 pulses are sent, the transmission motor drives the label belt to send 1mm forward.

N=L1/L2 is calculated, and N is fetched to obtain an integer according to the tailing method, that is, N=2. Amin=L2*N-L1-L3 coordinate is -8, Amax=L2*N-L1+L4 coordinate is -2, Bmin=L2*(N+1)-L1-L3 coordinate is 12, Bmax=L2*( N+1)-L1+L4 coordinates are 18.

The initial position is shown in Fig. 5A. Initially, the label transmission length command L5 is set to be consistent with the set length of a single label, that is, L5=L2=20mm, and the actual label transmission length L is 0mm.

The first process: In this process, a total of 720 pulses are sent to the conveying motor, and the label tape is sent forward by 12mm.

The system thinks that the end line of sensor 5 is about to enter the range of Bmin and Bmax, the actual label length and the set length are slightly different, and there will be slight differences in this area, but a margin needs to be guaranteed when setting L3 and L4, so here will not be affected.

During this transmission, the signal from sensor 5 is always considered invalid.

At the end of this process, the actual label delivery length L is 12mm, which is the same value as Bmin. The label transmission length command L5 is still 20mm, and the label position is shown in Figure 5B.

Second process: In this process, the end line of sensor 5 is in the interval between Bmin and Bmax, and the signal of sensor 5 is considered valid. Detect the signal of sensor 5 while sending pulses to the conveying motor. When the rising edge of the signal of sensor 5 is detected, that is, when the sensor detects the marking line of the label, ideally, a total of 180 pulses are sent to the conveying motor. Sent 3mm forward.

Since the actual label length is inconsistent with the set length, when the sensor detects the marking line of the label, the actual label transmission length L value is 15.2mm. Since the rising edge of the sensor 5 signal is detected, the instruction to update the label transmission length is L5=L1- L2*N+L=45-20*2+15.2=20.2mm.

When the sensor detects the marking line of the label, the label position is shown in Figure 5C.

Third process: In this process, the signal of the sensor 5 is considered invalid. When the actual label transmission length L value is the same as the updated label transmission length command L5=20.2mm, the process ends.

At the end of this process, no more pulses will be sent to the conveying motor, the conveying of the label will be stopped, and the cutting operation of the label will be realized. At this time, the position of the label is shown in Figure 5D.

After this process is over, this round of process will be repeated to realize the delivery and cutting of the next label.

It should be noted that although in this example the actual conveyed length is 20.2mm, it is 0.1mm longer than 20.1mm. However, in the transmission of the next label, since the initial position of the first label is less than 0.1mm, repeating the dynamic adjustment of the actual label feeding length command in this application, the length of the next label cut will be 20.1mm.

Third Embodiment

When there is a printing problem with the label, i.e. the marking line is not printed.

For example, the actual label length is 20mm, and the following parameters are set in the system: L1=45mm, L2=20mm, L3=3mm, L4=3mm; the relationship between the number of pulses received by the transmission motor and the distance it drives the label belt forward can be: For every 60 pulses sent, the conveying motor drives the label belt forward by 1mm.

N=L1/L2 is calculated, and N is fetched to obtain an integer according to the tailing method, that is, N=2. Amin=L2*N-L1-L3 coordinate is -8, Amax=L2*N-L1+L4 coordinate is -2, Bmin=L2*(N+1)-L1-L3 coordinate is 12, Bmax=L2*( N+1)-L1+L4 coordinates are 18.

The initial position is shown in FIG. 6A , and the label transmission length command L5 is initially set to be consistent with the set length of a single label, that is, L5=L2=20mm, and the actual label transmission length L is 0mm. The dotted line at the back marked line of the third label in the figure indicates unprinted.

The first process: In this process, a total of 720 pulses are sent to the conveying motor, and the label tape is sent forward by 12mm. The end line of sensor 5 is about to enter the interval between Bmin and Bmax. During this transmission process, the signal of sensor 5 is always considered invalid.

At the end of this process, the actual label delivery length L is 12mm, which is the same value as Bmin. The label transmission length command L5 is still 20mm, and the label position is shown in Figure 6B.

Second process: In this process, the end line of sensor 5 is in the interval between Bmin and Bmax, and the signal of sensor 5 is considered valid. The signal of the sensor 5 is detected while sending a pulse to the conveying motor, and when the rising edge of the signal of the sensor 5 is detected, that is, when the sensor detects the marking line of the label. In this case, since the marking line is not printed, the rising edge of the signal of the sensor 5 is not detected in both the Bmin and Bmax intervals.

This process ends when the end line of the sensor 5 is out of the Bmin and Bmax intervals. During the process, a total of 360 pulses were sent to the conveying motor, and the label tape was sent forward by 6mm.

Since the marking line is not detected, the label transmission length command is not updated, and L5 is still 20mm.

At the end of this process, the label position is shown in Figure 6C.

Third process: In this process, the signal of the sensor 5 is considered invalid. When the actual label transmission length L value is the same as the label transmission length command L5=20mm, the process ends.

At the end of this process, no more pulses will be sent to the conveying motor, and the conveying of the label will be stopped. At this time, the label position is shown in Figure 6D.

After the transmission is completed, a fault will be reported, and the customer will check and decide whether to continue the label cutting operation.

The above process shows that this algorithm can transmit the label according to the preset length even when the marking line is not printed, and when the next normal printed label is reached, it can continue to dynamically adjust to eliminate the accumulated error.

Fourth Embodiment

The Amin and Amax intervals are not used in the cases discussed above, and the Amin and Amax intervals will be used in this case, which is a rare occurrence. For example, when L1 is slightly larger than the value of L2*N, due to the deviation of the initial position of the label, the front marking line of the label is also behind the trailing line of the sensor 5 .

For example, the actual label length is 22mm, and the following parameters are set in the system: L1=45mm, L2=22mm, L3=3mm, L4=3mm; the relationship between the number of pulses received by the transmission motor and the distance it drives the label belt forward can be as follows : Every time 60 pulses are sent, the transmission motor drives the label belt to send 1mm forward.

N=L1/L2 is calculated, and N is fetched to obtain an integer according to the tailing method, that is, N=2. Amin=L2*N-L1-L3 coordinate is -4, Amax=L2*N-L1+L4 coordinate is 2, Bmin=L2*(N+1)-L1-L3 coordinate is 18, Bmax=L2*(N +1)-L1+L4 coordinates are 24.

The initial position of the label is shown in the actual situation in Fig. 7A, and the label is swung back by 1.5mm than the ideal situation. Initially, the label transmission length command L5 is set to be consistent with the set length of a single label, that is, L5=L2=22mm, and the actual label transmission length L is 0mm.

The first process: In this process, the end line of the sensor 5 is in the interval between Amin and Amax, and the signal of the sensor 5 is considered valid. Detect the signal of sensor 5 while sending pulses to the conveying motor. When the rising edge of the signal of sensor 5 is detected, that is, when the sensor detects the marking line of the label, in the actual situation, a total of 30 pulses are sent to the conveying motor. The belt was sent forward by 0.5mm.

When the sensor detects the marking line of the label, the actual label transmission length L is 0.5mm. Since the rising edge of the sensor 5 signal is detected, the command to update the label transmission length is L5=L1-L2*(N-1)+L= 45-22*(2-1)+0.5=23.5mm.

When the sensor detects the marking line of the label, the label position is shown in Figure 7B.

Second process: In this process, the signal of the sensor 5 is considered invalid. When the actual label transmission length L value is the same as the updated label transmission length command L5=23.5mm, the process ends.

At the end of this process, no more pulses will be sent to the conveying motor, the conveying of the label will be stopped, and the cutting operation of the label will be realized. At this time, the actual position of the label is shown in the actual situation in Figure 7C.

After these processes, the initial position of the next label is already correct.

If the Amin and Amax intervals are not introduced to judge the marking line, there will be special case 1. Since the label transmission length command is initially set to 22mm, the marking line cannot be detected within Bmin and Bmax. Everything will fail.

To sum up, the method described in this application can automatically identify and correct the cumulative error of label transmission, and perform real-time correction and compensation of positional deviation, which can ensure the accuracy of the cutting position, improve the cutting speed and product sewing quality, and reduce the labor cost of workers. The workload is improved, and the work efficiency is improved; the adaptability is strong, not only can sew labels of different sizes and styles, but also can be applied to capture other positioning, such as collar labels, etc.

When the distance corresponding to the length command of the label is sent, the sending of pulses is interrupted; when the transmission motor is interrupted, the label cutting device is ordered to cut the label tape, and at the same time, the number of sent pulses is cleared, and the actual label is sent. The length command is used as the initial feed length command to repeat the foregoing steps.
