[0002] In the shoemaking industry, composite midsoles are commonly used, generally including flannel fabric, midsole components, and sponge layers. In the prior art, the production of composite midsoles is generally done manually, by gluing the upper and lower surfaces of the midsole, and then attaching the flannel fabric and sponge layer separately. The method of manually composite midsoles has many disadvantages: 1. The operator needs to be in close contact with volatile glue for a long time, which has adverse effects on the operator's health; 2. During the manual composite midsole process, the flannel fabric and sponge layer of fixed shape and size need to be aligned with the midsole components and bonded separately, which is difficult to operate and has a high defective rate; 3.

[0024] The following are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] The present invention improves upon the prior art processing methods for three-layer midsoles. Existing three-layer midsoles rely heavily on manual assembly for processing. The specific method for manual assembly is: first, manually apply glue to the surface of the cut midsole pieces; then, align and attach a sponge layer of corresponding size to the surface of the midsole piece; then, apply glue to the bottom surface of the midsole piece; then, attach a velvet fabric to the bottom surface of the midsole; and finally, sequentially press the preliminarily attached midsole material for glue activation and pressing. Of course, some companies, in order to improve the processing quality of midsole materials, combine the sponge layer and velvet fabric in separate steps, activating and pressing the glue layer between the two independently, which is very time-consuming. Furthermore, during the step of attaching the sponge layer and velvet fabric, the shoe material layers need to be manually aligned, which can easily lead to defective products due to inaccurate alignment.

[0026] In order to solve the shortcomings of the existing manual assembly of midsoles, the present invention provides a three-in-one automatic assembly line for midsoles, including a body 1 and a first conveyor belt 21, a second conveyor belt 22 and a third conveyor belt 23 respectively arranged in parallel inside the body 1; a loading port 20 and an operating platform 201 are provided on the front side of the body 1, and the input ends of the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23 respectively extend out of the loading port 20 and extend to the table top of the operating platform 201; the conveying directions of the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23 are the same; a first transverse movement mechanism 3 and a first gluing device 4 are provided between the first conveyor belt 21 and the second conveyor belt 22; the second conveyor belt 22 is provided with a glue activation device 5, a first stacking device 6, a pressing device 7, a first turning device 8, a gluing guide device 9, a second gluing device 10 and a second turning device 11 in sequence along the transmission direction; a second stacking device 14 is provided at the end of the third conveyor belt 23. By placing the sponge layer, midsole parts and flannel fabric that make up the composite midsole on the input ends of the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23 in sequence, and using the processing devices at various stations on the conveyor belts to perform gluing, glue activation, stacking, pressing and other processes on these three layers of shoe materials, manual midsole composite processing is eliminated, production efficiency is improved, and the quality rate of products is increased.

[0027] The midsole assembly process of this automatic assembly line is as follows: the sponge layer, the midsole component and the flannel fabric are placed on the conveying starting points of the first conveyor belt 21, the second conveyor belt 22 and the third conveyor belt 23 respectively in sequence, and the sponge layer is laterally transferred to the second conveyor belt 22 under the gripping action of the first transverse movement mechanism 3. During this transfer process, the upper surface of the sponge layer passes through the first gluing device 4 and is glued; after the sponge layer is transversely moved by the first transverse movement mechanism 3, the sponge layer and the midsole component are placed side by side on the second conveyor belt 22, and pass through the glue activation device 5, the first stacking device 6, the pressing device 7, the first flipping device 8, the glue guide device 9, the second gluing device 10 and the second flipping device 11 in sequence to complete the glue activation treatment of the sponge layer, the first bonding treatment, the pressing treatment, the first flipping treatment, the glue brushing treatment on the bottom surface of the midsole component and the second flipping treatment; finally, under the gripping action of the second transverse movement mechanism, the semi-cost assembly of the sponge layer and the midsole component is transferred to the third conveyor belt 23, and the flannel fabric is bonded with the cooperation of the visual positioning device.

[0028] The second conveyor belt 22 is provided with a transfer position, a drying position, a stacking position, a pressing position, a flipping position and a gluing guide position in sequence along the transmission direction. The first transverse movement mechanism 3, the glue activation device 5, the first stacking device 6, the pressing device 7, the first flipping device 8 and the gluing guide device 9 are respectively arranged at the transfer position, the drying position, the stacking position, the pressing position, the flipping position and the gluing guide position. The transfer position, the drying position, the stacking position, the pressing position, the flipping position and the gluing guide position are respectively provided with an infrared sensing unit for detecting the shoe material. Each infrared sensing unit is electrically connected to the corresponding first transverse movement mechanism 3, the glue activation device 5, the first stacking device 6, the pressing device 7, the first flipping device 8 and the gluing guide device 9; when the shoe material is transferred to the transfer position, the drying position, the stacking position, the pressing position, the flipping position and the gluing guide position in sequence, the shoe material triggers and cooperates with the corresponding infrared sensing unit.

[0029] like Figure 3 As shown, specifically, the first transverse movement mechanism 3 includes a first transverse movement gantry 31, the first transverse movement gantry 31 spans the first conveyor belt 21 and the second conveyor belt 22, the first transverse movement gantry 31 is equipped with a horizontally arranged first transverse movement electric cylinder, the first transverse movement electric cylinder has a movable seat, the movable seat is equipped with a vertically arranged vertical drive cylinder, the vertical drive cylinder has an output shaft, and a suction cup unit 1000 is installed at the end of the output shaft, which is used to grip the shoe material under negative pressure. The first gluing device 4 is located on the front side of the first transverse movement gantry 31, and the first gluing device 4 has a gluing part. When the suction cup unit 1000 grips the shoe material and transfers it from the first conveyor belt 21 to the second conveyor belt 22, the first transverse movement mechanism 3 and the first gluing device 4 cooperate to brush glue, and the gluing part is located on the moving trajectory of the shoe material to realize gluing during the transfer of the shoe material.

[0030] A sponge layer positioning structure 35 is provided at the end of the first conveyor belt 21. This structure comprises two guide side panels symmetrically positioned on either side of the first conveyor belt 21, each with an inwardly inclined guiding bevel formed on its front side. The sponge layer, under the transmission action of the first conveyor belt 21 and the guidance of the beveled guiding edges, is positioned between the straight edges of the two guide side panels, completing its positioning. The sponge layer positioning structure 35 also includes an infrared sensing unit electrically connected to the first conveyor belt 21. Once the sponge layer is positioned, it triggers the infrared sensing unit, which sends an electrical signal to the equipment's control center, which stops the first conveyor belt 21, completing the process of preparing for the sponge layer's transverse movement.

[0031] A transfer station is located below the first transverse gantry 31. A baffle plate 36 is installed at this transfer station. The bottom surface of baffle plate 36 is spaced apart from the conveying surface of the second conveyor belt 22. The front side of the second conveyor belt 22 is angled to prevent misplacement of the midsole. Furthermore, when the sponge layer is transferred to the second conveyor belt 22, baffle plate 36 acts as a buffer. The forefoot portion of the sponge layer first contacts the second conveyor belt 22, while the heel portion of the sponge layer descends to the edge of baffle plate 36, placing the sponge layer in an inclined position and preventing glue backflow.

[0032] Specifically, the glue activation device 5 includes an activation frame shell, which is arranged across the second conveyor belt 22, and a heating component is provided inside the activation frame shell; the first stacking device 6 and the second stacking device 14 have the same structure, and each includes a multi-axis robot and another suction cup unit 1000, the multi-axis robot has an output shaft, and the suction cup unit 1000 is installed at the end of the output shaft of the multi-axis robot.

[0033] The first stacking device 6 and the second stacking device 14 are each equipped with a visual positioning device for stacking positioning. The multi-axis manipulator and the visual positioning device are used to complete the stacking of the shoe materials, with high stacking accuracy and low product defect rate.

[0034] like Figure 4 and Figure 5 As shown, the pressing device 7 comprises three pressing assemblies arranged in parallel along the conveying direction of the second conveyor belt 22. Each pressing assembly comprises a vertically mounted pressing cylinder 72 and a pressing module 73. The pressing module 73 comprises a module housing and four elastic pressing blocks 74. The module housing is fixedly mounted to the bottom end of the output shaft of the pressing cylinder 72, and each elastic pressing block 74 is elastically mounted in a stepped manner to the bottom of the module housing. This stepped arrangement of elastic pressing blocks 74 enables point-by-point downward pressure on the semi-finished midsole composed of the sponge layer and midsole component, preventing bubbles from forming in the glue layer between the two and improving the molding quality of the glue layer.

[0035] The first flipping device 8 includes a flipping gantry spanning the second conveyor belt 22, a flipping avoidance electric cylinder 81 arranged on the top of the gantry, an avoidance moving seat 82 arranged on the electric cylinder, a flipping vertical drive cylinder 83 arranged on the avoidance moving seat 82, and a first flipping rotary drive cylinder 84 arranged on the output shaft of the flipping vertical drive cylinder 83. The first flipping rotary drive cylinder 84 has a rotatably arranged output turntable, and a suction cup panel 85 is fixedly installed on the output turntable. The upper and lower surfaces of the suction cup panel 85 are respectively equipped with a negative pressure suction cup 86; the first flipping device 8 also includes a straight arm assembly, the straight arm assembly includes a straight arm bracket 87 fixed to one side of the second conveyor belt 22 and a straight arm drive cylinder 88 arranged on the top of the straight arm bracket 87. The straight arm drive cylinder 88 is vertically arranged, and the end of the output shaft of the straight arm drive cylinder 88 is equipped with another suction cup unit 1000. The flipping principle of the first flipping device 8 is: the semi-finished midsole after pressing is negatively gripped by the negative pressure suction cup 86; then, the first flip rotation drive cylinder 84 rotates the negative pressure suction cup 86 and the semi-finished midsole 180 degrees to make the bottom surface of the midsole face upward; finally, the bottom surface of the midsole is negatively gripped by the suction cup unit 1000 of the straight arm assembly, and the negative pressure suction cup 86 is moved laterally under the drive of the flip avoidance electric cylinder 81, and the straight arm drive cylinder 88 drives the suction cup unit 1000 and the semi-finished midsole downward, and the semi-finished midsole is placed back on the second conveyor belt 22 with the bottom surface facing upward, completing the first flip to cooperate with the next gluing step.

[0036] like Figure 4 and Figure 6 As shown, the glue-passing guide device 9 includes a downward-pressing crawler pushing device, which includes a glue-passing guide main frame arranged on one side of the second conveyor belt 22, a crawler side frame movably installed on the glue-passing guide main frame, a plurality of crawler rollers rotatably installed on the crawler side frames, and a crawler unit wound around each track roller, one of the crawler rollers is transmission-connected to a crawler pushing drive motor, and the crawler side frame is transmission-connected to a crawler lifting drive cylinder; the crawler unit is located at the end portion of the second conveyor belt 22, and a guide gap 90 is formed between the crawler surface of the crawler unit and the conveying surface of the second conveyor belt 22, and the pushing speed of the crawler unit is the same as the transmission speed of the second conveyor belt 22.

[0037] A reversing conveyor belt 221 is provided at the end of the second conveyor belt 22. The second gluing device 10 is located between the reversing conveyor belt 221 and the second conveyor belt 22. The second gluing device 10 is provided with another gluing section that is horizontally aligned with the guide gap 90. Since the semi-finished midsole completely passes through the gluing section of the second gluing device 10 along the conveying direction of the second conveyor belt 22, a forward propulsion force is required. The downward pressure crawler pushing device provides a forward propulsion force for the semi-finished midsole, preventing the semi-finished midsole from slipping on the conveying surface of the second conveyor belt 22 due to the damping effect of the gluing section.

[0038] like Figure 6 and Figure 7 As shown, the second flipping device 11 includes a Y-axis drive cylinder 111, a second flip rotation drive cylinder 112, a flip bracket 113, a finger cylinder 114 and two flexible clamping units 115. The Y-axis drive cylinder 111 is vertically arranged and located on the outside of the flip conveyor belt 221. The Y-axis drive cylinder 111 has a Y-axis slide that is movable up and down; the second flip rotation drive cylinder 112 is fixedly installed on the Y-axis slide, and the second flip rotation drive cylinder 112 has another rotatable output turntable; one side of the flip bracket 113 is fixedly connected to this output turntable; the finger cylinder 114 is fixedly installed on the other side of the flip bracket 113, and the finger cylinder 114 has two finger units that are close to or far away from each other; the two flexible clamping units 115 are respectively fixed to the finger units of the finger cylinder 114. The flipping principle of the second flipping device 11 is similar to that of the first flipping device 8. However, when the semi-finished midsole is transported to this flipping position, the upper surface of the semi-finished midsole is fully covered with glue after being processed by the second gluing device 10. The negative pressure gripper cannot adsorb and grip the upper surface of the semi-finished midsole. Therefore, a finger-type clamping structure is adopted in this step, and the semi-finished midsole with glue on its upper surface is clamped by two flexible clamping units 115.

[0039] Specifically, an intermediate carrier plate 13 is provided between the flip conveyor belt 221 and the first conveyor belt 21, and a convex nail structure 131 is provided on the disk surface of the intermediate carrier plate 13. The convex nail structure 131 includes a plurality of array-distributed convex nail units, which protrude from the disk surface of the intermediate carrier plate 13, and the protruding heights of each convex nail unit in the convex nail structure 131 are the same; a second transverse movement mechanism 12 is provided between the intermediate carrier plate 13 and the flip conveyor belt 221, and the second transverse movement mechanism 12 includes a second transverse movement cylinder 121 spanning the intermediate carrier plate 13 and the flip conveyor belt 221. The second transverse movement cylinder 121 has another movable seat, and a right-angle iron frame 122 is fixedly installed on the right-angle iron frame 122. A second vertical drive cylinder 123 is fixedly installed on the second vertical drive cylinder 123. The second vertical drive cylinder 123 has an output shaft, and another suction cup unit 1000 is installed at the end of the output shaft for gripping the shoe material with negative pressure. The intermediate carrier 13 is provided because the semi-finished midsole, once fully coated on one side with glue, needs to be repositioned using a visual device to coordinate with the stacking process between the semi-finished midsole and the velvet fabric on the third conveyor belt 23. To avoid damaging the newly applied glue layer on the semi-finished midsole, a stud structure 131 is provided on the surface of the intermediate carrier 13 to minimize the support provided by the newly applied glue layer. Furthermore, after being lifted by the suction cup unit 1000 of the second stacking device 14, any empty spots in the glue layer created by the stud structure 131 are automatically filled due to the surface tension of the glue, preventing bubbles from forming in the finished glue layer.

[0040] The automated assembly line provided in this embodiment does not provide for secondary pressing of the semi-finished midsoles. Instead, the semi-finished midsoles, after secondary gluing, are transferred and stacked onto the velvet fabric on the third conveyor belt 23, coordinated by a multi-axis manipulator and a visual positioning device. The fabric is then transported off the third conveyor belt 23 and sent to the next processing equipment. This automated assembly line can be integrated with various shoe material processing equipment to meet actual production needs, enabling automated production.

[0041] like Figure 8 As shown, this embodiment also provides a gluing device with an idle state. The above-mentioned first gluing device 4 and second gluing device 10 are respectively gluing devices with the same structure. The gluing device includes a gluing base, a conversion motor 101 and a glue box 102. The conversion motor 101 is fixed on the top of the gluing base, and the gluing base is movably installed on the fuselage 1; the output shaft of the conversion motor is provided with a turntable, and an assembly cross bar 103 is provided in the middle position of the turntable. The glue box is fixed to the upper part of the user's assembly cross bar 103, and the top of the glue box 102 is provided with a glue injection port, and the glue injection port is provided with a sealing cover 1021, and the bottom of the glue box is provided with a glue outlet; a glue brush roller 104 is provided at the front side end of the assembly cross bar 103, and the roller surface of the glue brush roller 104 is gap-matched with the glue outlet; a gluing cross bar 105 is installed at the bottom of the turntable, and a gluing gap is formed between the gluing cross bar 105 and the roller surface of the glue brush roller 104, that is, the above-mentioned gluing part. The gluing device is movably mounted on the machine body 1 via a gluing base and has an idle position and a gluing position for easy maintenance. In addition, when the gluing device is in the idle position, the conversion motor drives the turntable to rotate 180 degrees, causing the glue brush roller 104 and the glue outlet to face upward, preventing glue from flowing out when the device is idle.

[0042] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
