Description

Technical Field

[0001] The present invention relates to the field of shoe production, and in particular to an intelligent automatic production line for shoes. Background Art

[0002] Shoes are a tool for people to protect their feet and have a long history of development. In the production process of shoes, it is usually necessary to complete the processing and production of the upper first. The upper generally consists of two parts: the upper and the outsole. In the production process, the upper needs to be roughened and glued before being bonded and fixed to the outsole.

[0003] In the related art, the process of roughening and gluing the shoe upper is usually that the staff puts the shoe upper on the shoe last, and then places the shoe last in the roughening station and the gluing station in turn, and manually adjusts the position of the shoe last so that the grinding head of the roughening station and the brush of the gluing station can achieve the roughening and gluing of the shoe upper. After the shoe upper is polished and glued, the staff will glue the outsole to the bottom of the shoe upper.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the operations of roughening and gluing the shoe uppers are cumbersome and the work efficiency is low. Summary of the invention

[0005] In order to facilitate the roughening and gluing of the shoe upper and improve work efficiency, the present application provides an intelligent automated production line for shoes.

[0007] The gluing device includes a gluing frame, a gluing movement component, a gluing mounting seat, a gluing roller and a gluing drive component. The gluing movement component is installed on the gluing frame and is used to drive the gluing mounting seat to move in the vertical and horizontal directions. The gluing roller is rotatably installed on the gluing mounting seat and is used to roll and brush the upper of the shoe last. The gluing drive component is used to drive the gluing roller to rotate; the drying device is used to dry the shoe last conveyed by the conveying device; the gluing device and the gluing device are both provided with two groups, which are respectively set as the first gluing device, the second gluing device, the first gluing device and the second gluing device.

[0008] By adopting the above technical scheme, when roughening and gluing the shoe upper, the shoe upper is firstly put on the shoe last, and then the shoe last is conveyed by the conveying device. When the shoe last passes through the roughening device, the roughing grinding head roughens the shoe upper of the shoe last. After the roughening is completed, the shoe last continues to be conveyed. When the shoe last passes through the gluing device and the gluing device, the glue spraying component first sprays glue on the shoe upper of the shoe last, and then the gluing component cleans the shoe upper of the shoe last, and then the rolling brushing treatment of the shoe upper is realized by rotating the gluing roller, and then the shoe last continues to be conveyed. The drying device dries the upper put on the shoe last. The dried upper is then bonded to the outsole after being sprayed with glue, cleaned with a brush and rolled with a brush. In this process, the roughening and gluing of the upper does not require the staff to manually adjust the position of the shoe last. The intelligent and automatic production of shoes can be achieved by driving the corresponding components to move by a robotic arm. The operation is simple and conducive to improving work efficiency. In addition, the operation of drying the upper again after gluing and drying once is conducive to fully ensuring the stability of the subsequent bonding and fixing of the upper and the outsole.

The glue spraying mounting portion 41 is fixedly mounted on the first glue mounting portion 372 by bolts that penetrate the glue spraying strip hole 43 and the first glue mounting portion 372. The glue spraying baffle 42 is provided with a baffle strip hole 44 that is set through. The glue spraying baffle 42 is fixedly mounted on the glue spraying mounting portion 41 by bolts that penetrate the baffle strip hole 44 and the glue spraying mounting portion 41. The glue spraying baffle 42 is located on one side of the spraying direction of the spray gun 40. The setting of the glue spraying strip hole 43 and the baffle strip hole 44 facilitates the adjustment of the position of the glue spraying baffle 42, so as to facilitate the spraying of different sizes according to different processing techniques of different shoe uppers.

[0059] Reference Figure 8 and Fig. 9 The gluing assembly also includes a gluing motor 45 and a brush wheel 46. The brush wheel 46 is rotatably mounted on the second gluing mounting seat 37. The gluing motor 45 is fixedly mounted on the second gluing mounting seat 37 and drives the brush wheel 46 to rotate through the engagement of the bevel gears. After the spray gun 40 sprays the upper of the shoe last, the gluing motor 45 drives the brush wheel 46 to rotate to facilitate the cleaning of the upper of the shoe last.

[0060] Reference Fig.10The gluing device includes a gluing frame 47, a gluing motion component, a gluing mounting seat 48, a gluing roller 49 and a gluing driving component. The gluing motion component includes a first gluing linear module 50, a second gluing linear module 51 and a third gluing linear module 52. The first gluing linear module 50 is vertically installed on the gluing frame 47, the second gluing linear module 51 is horizontally installed on the slider of the first gluing linear module 50 and is perpendicular to the conveying direction of the top conveyor belt 2, the third gluing linear module 52 is vertically installed on the slider of the second gluing linear module 51, and the gluing mounting seat 48 is fixedly installed on the slider of the third gluing linear module 52, so that the gluing motion component drives the gluing mounting seat 48 to move in the vertical and horizontal directions. The two sets of vertically arranged linear modules are conducive to fully ensuring the accuracy of the mounting seat when moving in the vertical direction.

[0061] Reference Fig.11 and Fig.12 The glue driving assembly includes a glue motor 53, a glue driving roller 54 and a glue limiting roller 55. The glue roller 49 and the glue driving roller 54 are both rotatably mounted on the glue mounting seat 48 and are distributed from bottom to top in the vertical direction. A feeding groove 56 is provided on the outer peripheral surface of the glue driving roller 54. The feeding groove 56 is spiral and is evenly distributed around the axis of the glue driving roller 54. The glue motor 53 is mounted on the glue mounting seat 48 and drives the glue driving roller 54 to rotate through a commutator. The glue driving roller 54 drives the glue roller 49 to rotate in the opposite direction through the meshing of the gear set, i.e., two gears.

[0062] Reference Fig.12 Two gluing limiting rollers 55 are horizontally arranged and are rotatably mounted on the gluing mounting seat 48. The gluing limiting rollers 55 are each provided with a limiting plane 57 extending to both ends of their length direction. The heights of the two gluing limiting rollers 55 are both higher than the height of the gluing driving roller 54. The gluing mounting seat 48 is provided with a feeding cavity 58, which is located at the top of the gluing driving roller 54 and the bottom opening of the feeding cavity 58 is located between the two gluing limiting rollers 55. When the limiting rollers rotate, the limiting plane 57 conflicts with or does not conflict with the gluing driving roller 54, so that when the rubber material passes through the feeding cavity 58 and is placed on the gluing driving roller 54, the gluing driving roller 54 rotates to feed the rubber material to the gluing roller 49 through the feeding groove 56, so that the gluing roller 49 evenly rolls the rubber material onto the shoe surface, and the gap between the limiting plane 57 and the gluing driving roller 54 can be adjusted to synchronously adjust the amount of glue required by the gluing roller 49, which has strong applicability.

[0063] Reference Fig.11 and Fig.12In order to facilitate the rotation of the limiting roller, one end of the limiting roller is inserted outside the gluing mounting seat 48 and is fixedly connected to a driving plate 59. The gluing mounting seat 48 is fixedly installed with a gluing limiting member 60. The gluing limiting member 60 is provided with two gluing limiting grooves 61. The two driving plates 59 are respectively slidably matched in the two gluing limiting grooves 61 to further limit the rotation of the driving plate 59 and ensure the stability of the driving plate 59 when driving the limiting roller to rotate. The gluing frame is also equipped with two sets of clamping and conveying mechanisms and imaging mechanisms. The installation method of the two sets of clamping and conveying mechanisms and imaging mechanisms of the gluing frame is the same as that of the two sets of clamping and conveying mechanisms and imaging mechanisms of the roughening frame 17, so it will not be repeated here.

[0064] Replay Figure 1 , the gluing device and the gluing device are both provided with two groups and are respectively provided as the first gluing device, the second gluing device, the first gluing device and the second gluing device. The roughening device, the first gluing device, the first gluing device, the drying device, the second gluing device and the second gluing device are sequentially distributed along the conveying direction of the top conveyor belt 2. In the embodiment of the present application, the drying device is selected as a drying box 62. The top conveyor belt 2 and the bottom conveyor belt 3 are both passed through the drying box 62, so that the upper of the last is subjected to a second gluing treatment after being subjected to a gluing treatment and drying, thereby ensuring the stability of the upper during subsequent pre-bonding with the outsole.

[0065] Continue to refer to Figure 1 The high-speed production line also includes a double-layer drying device. The second gluing device, the second gluing device and the double-layer drying device are sequentially distributed along the conveying direction of the top conveyor belt 2. The double-layer drying device includes a double-layer drying box 63 and an outsole conveyor belt 64. The top conveyor belt 2, the bottom conveyor belt 3 and the outsole conveyor belt 64 are all arranged in the double-layer drying box 63. The outsole conveyor belt 64 is installed on the conveying frame 1 and is located on the top of the top conveyor belt 2. The conveying direction of the outsole conveyor belt 64 is opposite to that of the top conveyor belt 2. The outsole conveyor belt 64 is used to convey the outsole. When the outsole is bonded to the upper, it is first dried in the drying box 62, which is beneficial to ensure the stability of the outsole when it is pre-bonded with the upper after the two gluings. After the outsole is pre-bonded with the upper after the two gluings, it can quickly enter the double-layer drying box 63 for drying, which is convenient for the subsequent stable bonding process between the outsole and the upper.

[0066] The implementation principle of an intelligent automated production line for shoes in an embodiment of the present application is as follows: during the production process of the upper, the upper is firstly put on the shoe last, and then the shoe last is conveyed by the top conveyor belt 2 of the conveying device. When the shoe last passes through the roughening device, the shoe last is driven by the rodless cylinder 23 to move the clamping cylinder 24 horizontally to the position for polishing. When the shoe last enters the position for polishing, the imaging component 26 drives its own horizontal and vertical movement through the first imaging linear module 27 and the second imaging linear module 28 to take pictures or scan the size of the upper of the shoe last, so as to facilitate high-precision processing of uppers of different sizes through different preset programs.

[0067] After roughing is completed, the shoe last continues to be sent to the top conveyor belt 2 for transportation through the horizontal movement of the clamping cylinder 24 driven by the rodless cylinder 23. When the shoe last passes through the gluing device, it is conveyed and imaged by another set of clamping cylinders and imaging components 26 and then sent to the position where the workpiece is glued. The workpiece, i.e., the upper of the shoe last, is sprayed by the spray gun 40 and cleaned by the brush wheel 46 and then continues to be sent to the top conveyor belt 2 for transportation. When the shoe last is transported to the position of the glue roller 49, the second glue linear module 51 and the third glue linear module 52 drive the glue roller to move horizontally and vertically to achieve precise rolling brushing of the upper on the shoe last.

[0068] When the shoe last continues to be conveyed after rolling, the drying device dries the upper mounted on the shoe last. The dried upper is then bonded to the outsole after being sprayed, cleaned and rolled. During the bonding process of the outsole, it is first dried in the double-layer drying box 63, and then pre-bonded to the upper and then dried in the double-layer drying box 63, so that the staff can subsequently achieve stable bonding and fixing between the outsole and the upper. During the processing of the upper, the roughening and gluing of the upper do not require the staff to manually adjust the position of the shoe last. The corresponding components can be driven to move by the mechanical arm, which is easy to operate and conducive to improving work efficiency.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
