[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The terms "and" and "and" as used herein include any and all combinations of one or more of the associated listed items.

[0022] Please refer to the attached Figure 1 , an embodiment of the present invention proposes a control system based on a digital set control shoe production line, including a host computer (not shown in the figure), a first equipment area, a second equipment area, a third equipment area and a programmable controller (not shown in the figure) for controlling each shoe-making equipment in the first equipment area, the second equipment area and the third equipment area. The shoe-making equipment in the first equipment area is arranged horizontally, and the shoe-making equipment in the second equipment area and the third equipment area are arranged vertically, and the second equipment area and the third equipment area are respectively located on both sides of the first equipment area. The first equipment area, the second equipment area and the third equipment area form a U-shaped layout. The host computer is communicated with the programmable controller to set the equipment operating parameters of each shoe-making equipment in the first equipment area, the second equipment area and the third equipment area and to obtain the working data of each shoe-making equipment.

[0023] Specifically, in this embodiment, the programmable controller is preferably a PLC programmable controller. One shoemaking device can correspond to one PLC programmable controller, or multiple shoemaking devices can share one PLC programmable controller. The host computer communicates with the programmable controller through a network (such as Ethernet, Modbus, etc.), and all PLC programmable controllers are centrally controlled by the host computer.

[0024] It can be understood that the utility model realizes centralized management and automated control of each shoe-making equipment by setting operating parameters and acquiring working data of each shoe-making equipment in the first equipment area, the second equipment area, and the third equipment area through the host computer and the programmable controller, and the power on and off of each shoe-making equipment can also be uniformly controlled by the host computer.

[0025] The utility model helps to reduce the overall length of the workshop and optimize the layout by forming a U-shaped layout space among the first equipment area, the second equipment area and the third equipment area. At the corner between the first equipment area and the second equipment area and the third equipment area, one worker can operate two pieces of equipment at the same time, thereby reducing labor costs.

[0026] In this embodiment, the shoemaking equipment in the first equipment area includes, from left to right, a first activation machine 7 , an infrared rotary drying box 8 , and a second activation machine 9 .

[0027] The shoemaking equipment in the second equipment area includes, from bottom to top, a toe and heel shaping machine 1, a lasting machine 2, a shoe lasting and lacing machine 3, a lasting machine 4, a marking machine 5, and a roughening machine 6.

[0028] The shoemaking equipment in the third equipment area includes, from top to bottom, a hydraulic molding machine 10, a wrinkle removal and molding machine 11, a freezing molding machine 12, a shoe last pressing machine 13, and a needle inspection machine 14.

[0029] Specifically, the second equipment area, the first equipment area, and the third equipment area together form a complete shoe production line.

[0030] The toe and heel shaping machine 1 is used to heat and soften the shoe upper, and then put it on the shoe mold to cool and shape it, so that the shoe upper is shaped, which is convenient for subsequent workstations to perform lasting.

[0031] The lasting machine 2 is used to last the shaped shoe upper and sew the shoe upper into a fixed shape.

[0032] The softening, last-entering and shoelace-tying integrated machine 3 is used to soften the shoe material and fix it on the shoe last, and tie the shoelaces at the same time. Specifically, in the first step, the worker places the shoe upper (which already has the shape of a shoe, but does not have the sole part) on the hot air outlet of the machine, and softens the shoe upper again by blowing hot air. In the second step, the worker puts the shoe last into the softened upper and inserts it into the automatic last-fitting mechanism of the machine. The machine performs a rapid last-fitting action to tightly fit the shoe last and the upper together. In the third step, the put-on shoes are placed on the shoelace-tying clamp, and the worker manually ties the shoelaces.

[0033] The lasting machine 4 is used to process the heel part of the shoe. Specifically, the shoe with the shoe last and the shoe laces are inserted into the machine bracket of the lasting machine 4, and the machine presses and sweeps the heel of the shoe to make the heel of the shoe fit more closely and flatly with the shoe last (to facilitate the fit of the back with the sole).

[0034] The marking machine 5 is used to mark the shoe material for subsequent processing. Specifically, a worker stacks the upper and sole, places them on the marking machine 5, and secures them. The worker then manually marks the intersection of the upper and sole with a pen (to facilitate subsequent glue application and prevent glue from crossing the line).

[0035] The roughening machine 6 is used to roughen the shoe upper with the markings, so as to facilitate the subsequent brushing of glue and allow the glue to better penetrate into the shoe material.

[0036] The first activating machine 7 is used to dry the shoe uppers and soles after being sprayed with the medicine solution.

[0037] The infrared rotary drying box 8 is used to dry the glue applied on the upper and sole for the first time.

[0038] The second activation machine 9 is used to dry the uppers and soles after the second glue application to activate the viscosity of the glue. Specifically, after the workers apply glue for the second time on the dried uppers and soles, they place them in the second activation machine 9 for activation to activate the viscosity of the glue.

[0039] The hydraulic molding machine 10 is used to hydraulically mold the sole and upper. Specifically, workers assemble and fit the activated upper and sole and then put them into the hydraulic molding machine 10 for pressing, so that the upper and sole fit better under high pressure and are fixed under pressure at the same time.

[0040] The wrinkle removing and shaping machine 11 is used to remove wrinkles on the upper of the pressed and formed shoes to ensure a smooth appearance.

[0041] The freezing setting machine 12 is used to set the shoes after wrinkle removal through low temperature treatment.

[0042] The shoe last removing machine 13 is used to remove the formed shoes from the shoe last.

[0043] The needle detector 14 is used to detect finished shoes and screen out shoes with broken needles.

[0044] In this embodiment, a sole rack 15 is provided at the corner between the first equipment area and the second equipment area, and the sole rack 15 is used for placing the soles to be processed.

[0045] In this embodiment, an upper rack 16 is provided on one side of the shoe toe and heel forming machine 1 , and the upper rack 16 is used for placing the upper to be processed.

[0046] In one preferred embodiment of the present embodiment, the last pulling machine 13 and the softening and last-tying shoelace integrated machine 3 are further provided with a last returning device 17.

[0047] It can be understood that the last returning device 17 can deliver the last pulled out of the last pulling machine 13 to the softening and last-tying shoelace integrated machine 3 for use, reducing the time and labor intensity of manual carrying, accelerating the production rhythm, and improving the overall production efficiency. Specifically, the last returning device 17 can adopt a belt conveyor or a row of inclined pulleys, the pulleys being inclined from the last pulling machine 13 to the softening and last-tying shoelace integrated machine 3, and the last being placed on the pulley near the last pulling machine 13 after being pulled out, and automatically sliding to the side of the softening and last-tying shoelace integrated machine 3.

[0048] In the present embodiment, the control system further comprises a display screen module (not shown in the figure) in communication with the upper computer for displaying the device operation of each shoemaking device and the working data of each shoemaking device.

[0049] It can be understood that the display screen module can display the running state and working data of each shoemaking device in real time, and the operator can check the working condition of the device at any time, discover and solve potential problems in time, and ensure the smooth operation of the production line.

[0050] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application. The above embodiments only express the specific implementation of the present application, which is described in detail, but it should not be understood as a limitation of the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application.
