Description

Technical Field

[0001] This invention relates to the field of shoemaking, and in particular to a method and apparatus for tray diversion in a serial workstation. Background Technology

[0002] There are two types of automated glue spraying solutions for shoe production lines: online glue spraying and offline glue spraying. Offline glue spraying generally uses a two-station system, such as... Figure 1 As shown, shoes numbered 1-20 enter the glue spraying station in two stations, left and right, with a middle station set between them. This allows the left and right feet to enter the station separately, i.e., the left foot enters the left station and the right foot enters the right station. This ensures that the glue spraying posture of the left and right stations always maintains the same foot shape, which can improve glue spraying efficiency. However, if the incoming materials are coming in very quickly, a single workstation is insufficient to meet production requirements.

[0003] In response to this situation, existing technologies have proposed solutions such as... Figure 2 The proposed improvement involves setting up another workstation opposite the existing one. While this improves efficiency, it nearly doubles the width of the production line, making it unsuitable for situations where space is limited. Summary of the Invention

[0004] The main objective of this invention is to propose a serial workstation tray diversion method and apparatus that can improve workpiece processing efficiency and is applicable to situations where space width is limited.

[0005] This invention is achieved through the following technical solution: A serial workstation tray diversion method involves setting up a left workstation Sa1 and a right workstation Sa2 at intervals on the same side of a conveyor line transporting goods from left to right. The conveyor line has a first left position and a first right position corresponding to the left and right working positions of Sa1, a second left position and a second right position corresponding to the left and right working positions of Sa2, and a first reserve position and a second reserve position corresponding to Sa1 and Sa2, respectively. An intermediate position M1 is located between the first left and first right positions, and an intermediate position M2 is located between the second left and second right positions. The diversion method includes the following steps: Step S1: Number the unprocessed pallets on the conveyor line consecutively from right to left, starting from the first number. The pallet numbered j is represented as P. j Pallets with odd numbers can only enter the right workstation, and pallets with even numbers can only enter the left workstation. After steps S2, P1 and P2 are sequentially transported to the first right position and the first left position, they are transferred to the right working position and the left working position of Sa1 respectively. P3 and P4 are transferred to the right working position and the left working position of Sa2. P5 is transported to M1. Step S3, after the workpiece of P1 is processed, the workpiece of P2 starts to be processed, P1 is marked and pushed out to the first right position and released, P5 is transported to the first right position and transferred to the right working position of Sa1, after the workpiece of P2 is processed, P2 is marked and pushed out to the first left position and released, P6 is transported to the left working position of Sa1, P7 is transported to M2, and P8 is transported to the second preparation position; Step S4, after the workpiece on P3 is processed, the workpiece of P4 starts to be processed, P3 is marked and pushed out to the second right position and released, P7 is transported to the right working position of Sa2, after the workpiece of P4 is processed, P4 is marked and pushed out to the second left position and released, P8 is transported to the left working position of Sa2, and the next cycle is entered; Wherein, the tray processed by the rear working station needs to wait for the tray processed by the front working station to be released before being released.

[0006] Further, the conveying line is provided with card readers corresponding to the first preparation position, the first intermediate position, the second preparation position and the second intermediate position, the tray is provided with a chip for storing workpiece information, after the workpiece is processed, a mark indicating completion is set in the chip, when the card reader detects that the tray is marked, the tray is released, otherwise, the tray is blocked.

[0007] Further, the first left position and the first right position have two first intermediate positions therebetween, and the second left position and the second right position have two second intermediate positions therebetween.

[0008] Further, when Sa1 fails, the remaining unprocessed trays are temporarily not released, Sa1 is reset to push out the trays inside Sa1, and the trays are detected by the card reader corresponding to the first intermediate position, when it is detected that the tray has been marked, the tray is released, if not marked, the tray is transported to the second preparation position, and according to the number, the tray is sent to the second left position or the second right position of Sa2 for processing.

[0009] Further, if Sa1 is reset and returns to normal, the remaining unprocessed trays are renumbered from the right to the left from the beginning, and the workpiece processing is performed according to steps S1 to S4.

[0010] Further, if Sa1 is reset and still fails, Sa1 is shielded, and only Sa2 is relied on for processing, and after Sa1 returns to normal, the workpiece processing is performed again according to steps S1 to S4.

[0011] Further, when Sa2 fails, the tray is no longer distributed to Sa2, Sa2 is reset to push out the trays inside Sa2, and the trays are detected by the card reader corresponding to the second intermediate position, when it is detected that the tray has been marked, the tray is released, if not marked, the tray is blocked, and after being processed by manual, the tray is released.

[0012] Further, if Sa2 is reset to normal, continue to distribute the tray to Sa2, otherwise, shield Sa2 and only rely on Sa1 to process.

[0013] The application is also realized by the following technical solutions: A serial workstation tray distribution method, N workstations are sequentially and spacedly arranged on the same side of a conveying line conveying from left to right, for the i-th workstation Sa i , the conveying line has an i-th left position L i and an i-th right position R i corresponding to the left and right working positions of Sa i , at least one intermediate position M i is arranged between L i and R i , the distribution method comprises the following steps: Step S1, the unprocessed trays on the conveying line are continuously numbered from right to left from the beginning, the tray numbered j is represented as P j , the tray numbered odd number can only enter the right working position, and the tray numbered even number can only enter the left working position; Step S2, P1 and P2 are sequentially conveyed to the right and left working positions of the workstation Sa1, P3 and P4 are sequentially conveyed to the right and left working positions of the workstation Sa2, and so on until P 2N-1 and P 2N are sequentially conveyed to the right and left working positions of the workstation Sa N , P 2N+1 is conveyed to M1; Step S3, after the workpiece of P1 is processed, the workpiece of P2 starts to be processed, P1 is marked and pushed out of R1 and released, P 2N+1 is conveyed to the right working position of the workstation Sa1, after the workpiece of P2 is processed, P2 is marked and pushed out of L1 and released, P 2N+2 is conveyed to the left working position of the workstation Sa1, P 2N+3 is conveyed to M2, P 2N+4 is conveyed to a standby position between R1 and L2; Step S4, the trays in the workstations Sa2 to Sa N are processed in sequence according to step S3, and when all the trays are processed, the next cycle is entered; Wherein, N≥3, i=1,2,…,N, and j is an integer.

[0014] The application is also realized by the following technical solutions: A diversion device for implementing the serial workstation tray diversion method described above is characterized by comprising: a conveyor line transporting data from left to right; N workstations arranged at intervals on the same side of the conveyor line from left to right; N left positions, N right positions, multiple middle positions arranged on the conveyor line; multiple blocking mechanisms and card readers; and a control mechanism, wherein the i-th left position L... i and the i-th right position R i Corresponding to the i-th workstation Sa i The left and right workstations, L i and R i At least one intermediate bit M is set between them. i The control mechanism controls the operation of the conveyor line and each workstation to process the workpieces on the pallet. The pallet is equipped with a chip that stores workpiece information. When the workpiece is processed, the control mechanism sets a mark in the chip to indicate completion. After the card reader detects that the pallet has been marked, the control mechanism controls the blocking mechanism to release the pallet. Otherwise, the blocking mechanism blocks the pallet.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, a left workstation and a right workstation are spaced apart on the same side of the conveyor line. Pallets numbered odd can only enter the right workstation, and pallets numbered even can only enter the left workstation. In the first cycle, P1 and P2 are sequentially conveyed to the first right position and the first left position, and then transferred to the right and left workstations of Sa1, respectively. P3 and P4 are transferred to the right and left workstations of Sa2, and P5 is conveyed to M1. After the workpiece of P1 is processed, the workpiece of P2 begins to be processed. P1 is marked and pushed out to the first right position and released. P5 is conveyed to the first right position and transferred to the right workstation of Sa1. After workpiece P2 is processed, P2 is marked and pushed to the first left position and released. P6 is transported to the left working position of Sa1, P7 is transported to M2, and P8 is transported to the preparatory position located between the first right position and the second left position. After workpiece P3 is processed, workpiece P4 begins to be processed. P3 is marked and pushed to the second right position and released. P7 is transported to the right working position of Sa2. After workpiece P4 is processed, P4 is marked and pushed to the second left position and released. P8 is transported to the left working position of Sa2. After workpieces P5, P6, P7, and P8 are all processed, the next cycle begins. This effectively improves workpiece processing efficiency without increasing the footprint, making it suitable for situations where space width is limited. Furthermore, this invention enables first-in, first-out (FIFO), ensuring that the processed workpieces are arranged in the same order as before processing, thus preventing the processed workpieces from being misaligned with their accessories and affecting subsequent processes.

[0016] 2. When the workstation is faulty, the faulty workstation can be shielded, and only single workstation is used for production. When the workstations are normal, the number of workstations for production can be selected according to the demand, and the flexibility is higher.

[0017] 3. Multiple workstations can be expanded according to the demand, and the flexibility is further improved. BRIEF DESCRIPTION OF DRAWINGS

The chip of the tray on which the workpiece is processed is provided with a flag bit in advance. The PLC modifies the flag bit to mark the tray. The specific process is prior art. The process of reading the number and flag bit by the card reader is also prior art. A plurality of blocking mechanisms are provided on the conveying line 1 to block or release the unprocessed tray according to the detection result of the corresponding card reader. An end detection position 13 is provided at the end of the conveying line. The card reader of the end detection position 13 detects all the trays released to the end detection position 13 again. If it is detected that the tray is not marked, it is blocked and waits for manual processing. The tray structure, chip structure, card reader 4 structure and blocking mechanism are all prior art.

[0028] After the workpiece on P3 is processed, the workpiece on P4 is processed, P3 is marked and pushed out to the second right position R2 and released, P7 is conveyed to the right working position 32 of Sa2, the workpiece on P4 is processed, P4 is marked and pushed out to the second left position L2 and released, P8 is conveyed to the left working position 31 of Sa2, and the workpiece on P5, P6, P7 and P8 is processed in the next cycle. After processing, P9 and P 10 P1 and P2 are located at the right working position 22 and the left working position 21 of the left station Sa1 respectively. 11 P3 and P4 are located at the right working position 32 and the left working position 31 of the right station Sa2 respectively. 12 P3 and P4 are located at the right working position 32 and the left working position 31 of the right station Sa2 respectively. The tray processed by the rear station needs to be released after the tray processed by the front station is released.

[0029] In this embodiment, the station is a glue spraying station, and the workpiece is a shoe upper. The glue spraying robot in the glue spraying station sprays glue on the shoe upper. The glue spraying robot is located between the left working position and the right working position. The glue spraying robot sprays glue on the shoe upper on the right working position first and then sprays glue on the shoe upper on the left working position.

[0030] If there are 20 unprocessed trays, they are sequentially arranged from left to right as P 20 P 10 …P2P1, after steps S1 to S4, the left station Sa1 processes P1, P2, P5, P6, P9, P 10 , P 13 , P 14 , P 17 , P 18 , the right station Sa2 processes P3, P4, P7, P8, P 11 , P 12 , P 15 , P 16 , P 19 , P 20 , the order of the processed trays is still P20 P 10 …P2P1, so as to ensure that the vamp does not appear misalignment in subsequent matching with the sole.

[0031] When the workstation fails, the processing is as follows: When the left workstation Sa1 fails, the remaining untreated trays are temporarily not released, Sa1 is reset to push the internal trays out, and the trays are detected by the card reader 4 corresponding to the first intermediate position M1. When it is detected that it has been marked, it is released, and if it is not marked, it is transported to the second preparation position 12. The second preparation position 12 reads the number, and the control mechanism sends it to the second left position L2 or the second right position R2 of Sa2 for processing according to the number. The control mechanism is prior art, and the process of sending the tray to the left or right position of the corresponding workstation according to the tray number is also prior art.

[0032] If the left workstation Sa1 is reset and returns to normal, the remaining untreated trays are renumbered from the right to the left from the beginning, and the workpiece processing is performed according to steps S1 to S4. If the left workstation Sa1 is reset and still fails, the left workstation is shielded, and only the right workstation Sa2 is used for processing. After the left workstation Sa1 returns to normal, the workpiece processing is performed again according to steps S1 to S4.

[0033] When the right workstation Sa2 fails, the trays are temporarily not distributed to Sa2, Sa2 is reset to push the internal trays out, and the trays are detected by the card reader corresponding to the second intermediate position M2. When it is detected that it has been marked, it is released, and if it is not marked, it is blocked and released after being processed manually.

[0034] If the right workstation Sa2 is reset and returns to normal, the trays continue to be distributed to the right workstation Sa2, otherwise, the right workstation Sa2 is shielded and only the left workstation Sa1 is used for processing.

[0035] When only the left workstation Sa1 or only the right workstation Sa2 works, the working process is the same as that disclosed in the invention patent "A vamp glue spraying shunting method" with publication number CN120604897B.

[0036] Example two: The difference between this embodiment and example one is only: The first embodiment is provided with two first intermediate positions between the first left position and the first right position, and two second intermediate positions between the second left position and the second right position. When the tray on the right intermediate position has been released from the standby position, and the workpiece on the tray in the right working position has been processed, the workpiece in the left working position is processed in the process of pushing out the tray. When the workpiece in the left working position has been processed, if the tray on the right intermediate position has not been transported to the right working position, the tray in the left working position is pushed out to the left intermediate position, and the tray on the standby position is released to the left working position. In this way, the left working position does not have to wait for the tray in the intermediate position to be transported to the right working position before starting to push out, so that the pace of tray release is improved, and the work efficiency is further improved.

[0037] Embodiment Three The difference between the present embodiment and the first embodiment is that: As shown in Figure 5 , the present embodiment has three working stations. The distribution method of the present embodiment is similar to that of the first embodiment, and the N working stations are described as follows: Step S1, the trays on the conveying line that have not been processed are numbered from right to left in sequence, and the tray numbered j is represented as P j . The tray numbered with an odd number can only enter the right working position, and the tray numbered with an even number can only enter the left working position. Step S2, P1 and P2 are transported to the right working position and the left working position of the working station Sa1 in sequence, P3 and P4 are transported to the right working position and the left working position of the working station Sa2 in sequence, and the process is repeated until P 2N-1 and P 2N are transported to the right working position and the left working position of the working station Sa N , P 2N+1 is transported to M1. Step S3, after the workpiece of P1 is processed, the workpiece of P2 starts to be processed, P1 is marked and pushed out to R1 and released, P 2N+1 is transported to the right working position of the working station Sa1, after the workpiece of P2 is processed, P2 is marked and pushed out to L1 and released, P 2N+2 is transported to the left working position of the working station Sa1, P 2N+3 is transported to M2, P 2N+4 is transported to the standby position between R1 and L2. Step S4, the trays in the working stations Sa2 to Sa N are processed in sequence according to step S3, and when all the trays are processed, the next cycle is entered. The processing of the trays in the working station Sa2 is as follows: After the workpiece of P3 is processed, the workpiece of P4 starts to be processed, P3 is marked and pushed out to R2 and released, P2N+3 After the workpiece processing of P4 is completed, P4 is marked and pushed out to L2 and released, and P 2N+4 The workpiece P4 is conveyed to the left working position of the working station Sa2. 2N+5 The workpiece P4 is conveyed to M3, P 2N+6 The workpiece P4 is conveyed to the standby position between R2 and L3. Wherein, N≥3, i=1, 2, …, N, and j is an integer.
