Description

Technical Field

[0001] The utility model relates to the technical field of sole processing equipment, in particular to a feeding device for shoe lasts. Background Art

[0002] Shoe lasts are essential forming tools in the shoe processing process. Shoe lasts not only determine the shape and style of the shoes, but also determine whether the shoes fit the feet. Therefore, during the production process, each pair of shoes requires a shoe last of corresponding shape for processing due to their different styles and sizes. However, since shoe factories produce many styles of shoes, and each style requires processing of a large number of different sizes, in order to save production costs, only a certain amount of shoe lasts of the same style and size will be used. Therefore, the shoe lasts need to be recycled. After the shoe processing is completed, the following work needs to be done: first, the shoes are pulled out of the shoe lasts, and then, the shoe lasts are classified into collection baskets according to the size and style of the shoes. This will greatly increase the workload of the staff and increase labor costs. The staff also needs to transport the classified collection baskets to the processing area, which is also time-consuming and labor-intensive. In addition, when the staff manually sorts the shoe lasts into different collection baskets, sorting errors are prone to occur. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a feeding device for shoe lasts which has a high degree of automation, can reduce labor costs, and ensures that shoe lasts can be accurately sorted into corresponding collection baskets.

[0004] The technical solution of the utility model is as follows: a feeding device for shoe lasts, comprising a shoe last, an equipment base, a shoe last feeding device connected to the equipment base, a shoe last discharging device connected to the equipment base, a shoe last pulling device connected to the equipment base and a controller, wherein the shoe last feeding device comprises a transmission frame connected to the equipment base, a first transmission belt connected to the transmission frame and a first driving motor for driving the first transmission belt to move, the shoe last discharging device comprises a second transmission belt connected to the equipment base and a second driving motor for driving the second transmission belt to move, the second transmission belt is located directly below the first transmission belt, a placement opening is provided on the equipment base, the placement opening is located at the end of the first transmission belt, the placement opening is located directly above the second transmission belt, a positioning hole is provided on the shoe last, the shoe last pulling device comprises a shoe pulling rod connected to the equipment base, the shoe pulling rod is adapted to the cross-sectional shape and size of the positioning hole, the shoe pulling rod is close to the placement opening, and the controller is electrically connected to the first driving motor and the second driving motor respectively.

[0005] By adopting the above technical scheme, first, the staff places the processed shoes together with the shoe lasts on the first conveyor belt, and then controls the first drive motor through the controller to drive the first conveyor belt to move, so that the shoe last and the shoes move together in the direction of the placement port. When moving to the placement port position, the staff removes the shoes and the shoe last together, and then aligns the positioning hole on the shoe last with the shoe pulling rod and inserts it, thereby fixing the position of the shoe pulling rod so that it cannot move horizontally. The staff then manually pulls the shoes to separate the shoes from the shoe last, and then the staff places the processed shoe lasts through the placement port onto the second conveyor belt, and controls the second drive motor through the controller to drive the second conveyor belt to move, so that the second conveyor belt drives the shoe last to complete the unloading work, wherein the other end of the second conveyor belt can be set in the processing area, which can further reduce the manpower required for the staff to carry the shoe lasts.

[0006] Further configuration of the utility model: a QR code label is provided on the top of the shoe last, and the QR code label records the style information and size information of the shoe last; the device base is also provided with an information scanner fixedly connected to the device base, and the information scanner can identify the information on the QR code label; the device base is also provided with a sliding base slidably connected to the device base, a plurality of collecting baskets connected to the sliding base, and a hydraulic cylinder for driving the sliding base to move in a horizontal direction; the movement direction of the sliding base is perpendicular to the movement direction of the second conveyor belt, the position of the collecting basket corresponds to the position of the second conveyor belt, the information scanner is located directly above the second conveyor belt, and the information scanner and the hydraulic cylinder are respectively electrically connected to the controller.

[0007] By adopting the above technical solution, since a QR code label is provided on the top of the shoe last, and the style information and size information of the shoe last are recorded on the QR code label, when the shoe last moves to the position of the information scanner through the second conveyor belt, the information scanner scans the information on the QR code label and transmits the information to the controller. The controller controls the hydraulic cylinder to drive the sliding base to move horizontally according to the style information and size information of the shoe last recorded on the QR code label, so that the collection basket with the same category as the shoe last moves to the corresponding position of the second conveyor belt, and the shoe last automatically falls from the second conveyor belt into the corresponding collection basket. In this way, the sorting of shoe lasts can be automatically completed, further reducing labor costs. At the same time, compared with the manual sorting of shoe lasts, this sorting method can further reduce the sorting error rate.

[0008] The utility model is further configured as follows: a photoelectric sensor fixedly connected to the device base is provided on the device base, the position of the light signal emitted by the photoelectric sensor corresponds to the position on the second conveyor belt directly below the information scanner, and the controller is electrically connected to the photoelectric sensor. With the above technical solution, when the shoe last moves to the position corresponding to the light signal emitted by the photoelectric sensor, the controller controls the second conveyor belt to stop working. Since the position of the light signal emitted by the photoelectric sensor corresponds to the position on the second conveyor belt directly below the information scanner, it can be ensured that the shoe last is in a stationary state at this time, and the information scanner can clearly scan the information recorded on the QR code label on the shoe last, thereby avoiding the inability to accurately sort the shoe last into the collection basket due to the failure of the information scanner to scan clearly.

[0009] The utility model is further configured as follows: a weighing sensor is provided at the bottom of the collection basket, an alarm is also provided on the equipment base, each collection basket is provided with an independent weighing sensor, and the controller is electrically connected to the weighing sensor and the alarm respectively.

[0010] With the above technical solution, since each collecting basket is equipped with an independent weighing sensor, the staff can set a threshold value in the weighing sensor according to the average weight of each shoe last and the weight in the collecting basket when each collecting basket is full of shoe lasts. When the shoe lasts placed in the collecting basket reach the threshold value, the weighing sensor sends an electrical signal to the controller, and the controller controls the second drive motor to stop working. At the same time, the controller controls the alarm to sound an alarm, and the staff will take away the collecting basket full of shoe lasts to avoid the mixing of shoe lasts of different styles and sizes due to the shoe lasts overflowing from the collecting basket due to the collection basket being full. In addition, this can further reduce labor costs. The staff does not need to pay attention to the situation in the collecting basket all the time, and only needs to process the collecting basket when the alarm sounds.

[0016] First, the staff places the processed shoes together with the shoe last 1 on the first conveyor belt 8, and then controls the first drive motor 9 through the controller 6 to drive the first conveyor belt 8 to move, so that the shoe last 1 and the shoes move together in the direction of the placement opening 12. When moving to the position of the placement opening 12, the staff removes the shoes connected to the shoe last 1, and then aligns the positioning hole 13 on the shoe last 1 with the shoe pulling rod 14 and inserts it, thereby fixing the position of the shoe pulling rod 14 so that it cannot move horizontally. Then the staff manually pulls the shoes to separate the shoes from the shoe last 1, and then the staff puts the processed shoe last 1 through the placement opening 12 onto the second conveyor belt 10, and controls the second drive motor 11 through the controller 6 to drive the second conveyor belt 10 to move, so that the second conveyor belt 10 drives the shoe last 1 to complete the discharging work, wherein the other end of the second conveyor belt 10 can be set in the processing area, which can further reduce the manpower required for the staff to carry the shoe last 1.

[0017] A QR code label 15 is provided on the top of the shoe last 1, and the QR code label 15 records the style information and size information of the shoe last 1. The equipment base 2 is also provided with an information scanner 16 fixedly connected to the equipment base 2, and the information scanner 16 can identify the information on the QR code label 15. The equipment base 2 is also provided with a sliding base 17 slidably connected to the equipment base 2, a plurality of collecting baskets 18 connected to the sliding base 17 and a hydraulic cylinder 19 for driving the sliding base 17 to move horizontally. The movement direction of the sliding base 17 is perpendicular to the movement direction of the second conveyor belt 10, and the position of the collecting basket 18 corresponds to the position of the second conveyor belt 10. The information scanner 16 is located directly above the second conveyor belt 10, and the information scanner 16 and the hydraulic cylinder 19 are respectively electrically connected to the controller 6. Since a QR code label 15 is provided on the top of the shoe last 1, and the style information and size information of the shoe last 1 are recorded on the QR code label 15, when the shoe last 1 moves to the position of the information scanner 16 through the second conveyor belt 10, the information scanner 16 scans the information on the QR code label 15 and transmits the information to the controller 6. The controller 6 controls the hydraulic cylinder 19 to drive the sliding base 17 to move horizontally according to the style information and size information of the shoe last 1 recorded on the QR code label 15, so that the collection basket 18 of the same category as the shoe last 1 moves to the corresponding position of the second conveyor belt 10, and the shoe last 1 automatically falls from the second conveyor belt 10 into the corresponding collection basket 18. In this way, the sorting work of the shoe last 1 can be automatically completed, further reducing the labor cost. At the same time, compared with the manual sorting method of the shoe last 1, this sorting method can further reduce the sorting error rate.

[0018] The device base 2 is provided with a photoelectric sensor 20 fixedly connected to the device base 2. The position of the light signal emitted by the photoelectric sensor 20 corresponds to the position on the second conveyor belt 10 directly below the information scanner 16. The controller 6 is electrically connected to the photoelectric sensor 20. When the shoe last 1 moves to the position corresponding to the light signal emitted by the photoelectric sensor 20, the controller 6 controls the second conveyor belt 10 to stop working. Since the position of the light signal emitted by the photoelectric sensor 20 corresponds to the position on the second conveyor belt 10 directly below the information scanner 16, it can be ensured that the shoe last 1 is in a stationary state at this time, and the information scanner 16 can clearly scan the information recorded on the two-dimensional code label 15 on the shoe last 1, thereby avoiding the shoe last 1 from being accurately sorted into the collection basket 18 due to the failure of the information scanner 16 to scan clearly. A weighing sensor 21 is provided at the bottom of the collection basket 18, and an alarm 22 is also provided on the device base 2. Each collection basket 18 is provided with an independent weighing sensor 21, and the controller 6 is electrically connected to the weighing sensor 21 and the alarm 22 respectively.

[0019] Since each collecting basket 18 is provided with an independent weighing sensor 21, the staff can set a threshold value in the weighing sensor 21 according to the average weight of each shoe last 1 and the weight in the collecting basket 18 when each collecting basket 18 is full of shoe lasts 1. When the shoe lasts 1 placed in the collecting basket 18 reaches the threshold value, the weighing sensor 21 sends an electrical signal to the controller 6, and the controller 6 controls the second drive motor 11 to stop working. At the same time, the controller 6 controls the alarm 22 to sound an alarm, and the staff will take away the collecting basket 18 full of shoe lasts 1 to avoid the shoe lasts 1 overflowing from the collecting basket 18 due to the collection basket 18 being full, thereby causing shoe lasts 1 of different styles and sizes to be mixed. In addition, this can further reduce labor costs. The staff does not need to pay attention to the situation in the collecting basket 18 all the time, and only needs to process the collecting basket 18 when the alarm 22 sounds.
