[0002] In the process of shoemaking, the thickness and elasticity of the leather uppers vary greatly. The thickness and elasticity of different parts of the same leather are different, and the differences between different leathers are even greater, which brings great uncertainty to the accuracy of leather scraping. Under this condition, using manual upper overlap operations will lead to larger upper size errors, resulting in unqualified uppers and cost waste for the factory. In addition, in the manufacturing process of upper overlap, it is often necessary to apply glue on the sole for adhesion, etc., and the traditional gluing method is mostly manual gluing, which is difficult to control the thickness of the glue, not only affecting production efficiency but also affecting the quality of the shoes.

[0042] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0043] The invention discloses an automatic upper overlap production device, which is used for overlapping and bonding two upper surfaces. The invention is described below through specific embodiments.

[0044] Please refer to Figure 1-3 The automatic upper lap production equipment includes a frame 1, a lap mechanism 2, and a leather scraping mechanism 3. And a glue brushing mechanism 4; the overlapping mechanism 2, the scraping mechanism 3 and the glue brushing mechanism 4 are installed on the frame 1, the overlapping mechanism 2 includes an up and down moving cylinder 21 and a first suction fixing plate 22 for placing the first upper surface, the first suction fixing plate 22 is fixed on the piston rod of the up and down moving cylinder 21, and the frame 1 is provided with a second suction fixing plate for placing the second upper surface. In this embodiment, the area of ​​the first upper surface is smaller than the area of ​​the second upper surface; the scraping mechanism 3 is used to scrape the skin of the overlapping part of the first upper surface, and the purpose of the scraping treatment is to make the overlapping part of the first upper surface form a burr state, so that it can be more firmly bonded to the second upper surface after brushing glue, and the glue brushing mechanism 4 is used to brush glue on the overlapping part of the first upper surface and the overlapping part of the second upper surface; the up and down moving cylinder 21 drives the first upper surface on the first suction fixing plate 22 to move to the scraping and glue brushing processing station for scraping and brushing, and then drives the first upper surface to move to the overlapping station for overlapping and bonding with the second upper surface.

[0045] Specifically, in order to save space and make rational use of space, the second suction fixing plate is arranged on the plane at the top of the frame 1, and a working window is opened at a position near the second suction fixing plate on the top of the frame 1. The function of the working window is to facilitate the first suction fixing plate 22 to lift the first upper surface to be flush with the second upper surface, so as to facilitate the overlapping and bonding of the two. However, it should be noted that the overlapping part of the first upper surface and the overlapping part of the second upper surface are two mutually fitting inclined surfaces. The purpose of this design is to ensure that the first upper surface and the second upper surface are smooth after overlapping and bonding, so as to avoid unevenness in the overlapping part, which affects the beauty and flatness of the upper surface.

[0046] For further information, please refer to Figure 1-3 The overlapping mechanism 2 further includes a rotating motor 23 and an upper pressing plate 24; the rotating motor 23 is fixed on the first suction fixing plate 22, and one side of the upper pressing plate 24 is connected to the output shaft of the rotating motor 23. The designed upper pressing plate 24 is conducive to the first upper surface being closely attached to the first suction fixing plate 22 to prevent it from moving.

[0047] For further information, please refer to Figure 1-3The device also includes an overlap auxiliary mechanism 7; the overlap auxiliary mechanism 7 includes a bracket 71, a downward pressure cylinder 72 and a third suction fixing plate 73; the bracket 71 is fixed on the frame 1, the downward pressure cylinder 72 is connected to the bracket 71, the third suction fixing plate 73 is fixed on the piston of the downward pressure cylinder 72, and the lower surface of the third suction fixing plate 73 faces the second suction fixing plate. The function of the third suction fixing plate 73 is to absorb and fix the overlapping part of the second upper surface to prevent the overlapping part of the second upper surface from falling into the working window after the first suction fixing plate 22 leaves the working window. In addition, the function of the downward pressure cylinder 72 is to play a pressing role when the first upper surface and the second upper surface are overlapped and bonded.

[0048] For further information, please refer to Figure 1-3 The scraping mechanism 3 includes a first front and rear sliding module 31 and an electric grinder 32; the electric grinder 32 is slidably connected to the first front and rear sliding module 31. The first front and rear sliding module is mainly composed of a slide rail and a slider, and its function is to drive the electric grinder 32 to move forward and backward to grind the overlapping part of the first upper surface, so that burrs appear on the surface of the grinded part. In order to avoid the grinding waste chips remaining on the first upper surface, the equipment is also provided with a dust suction mechanism 5. In this embodiment, the dust suction mechanism 5 is installed on the glue brushing mechanism 4; the dust suction mechanism 5 includes a vacuum cleaner and a dust suction pipe (not shown in the figure); one end of the dust suction pipe is connected to the dust suction port of the vacuum cleaner, and the other end is close to the first suction fixing plate 22. During the grinding process, the vacuum cleaner is turned on synchronously, and the waste chips are sucked away along the dust suction pipe under the suction force of the vacuum cleaner.

[0049] For further information, please refer to Figure 1-3 The glue brushing mechanism 4 includes a second front-to-back sliding module 41, a flip assembly 42 and a glue brushing assembly 43; the flip assembly 42 includes a flip seat 423, a flip shaft 421 and a flip cylinder 422; the flip seat 423 is slidably connected to the second front-to-back sliding module 41, the flip cylinder 422 is fixed to the flip seat 423, one end of the flip shaft 421 is transmission-connected to the flip cylinder 422, and the other end of the flip shaft 421 is connected to the glue brushing assembly 43. The second front-to-back sliding module is mainly composed of a slide rail and a slider, and its function is to drive the glue brushing assembly 43 to move forward and backward. The function of the flip assembly 42 is to change the direction of the glue brushing assembly 43. The glue brushing head 434 of the glue brushing assembly 43 is facing upwards to apply glue to the overlapping part of the second upper surface, and the glue brushing head 434 of the glue brushing assembly 43 is facing downwards to apply glue to the overlapping part of the first upper surface.

[0050] For details, please refer to Figure 4-7The glue brushing assembly 43 includes a connecting plate 436, a flexible connecting piece 4361, a glue gun fixing head 4331, a glue gun 433, a glue brushing head 434, an elastic connecting tube 435 and a fixing plate 431; the upper end of the glue gun fixing head 4311 is connected to the lower end of the glue brushing head 434 through the elastic connecting tube 435, the fixing plate 431 is connected to the flip shaft 421, and the elastic connecting tube 435 plays the role of glue passing and flexible connection. Specifically, since the elastic connecting tube 435 is a hose, it is only necessary to design the glue gun fixing head 4311 and the glue brushing head 434 and one end of the elastic connecting tube 435 to have a diameter suitable for the elastic connecting tube 435, so that the elastic connecting tube 435 can be sleeved with the glue gun fixing head 4311 and the glue brushing head 434. The lower end of the glue gun fixed head 4311 is connected to the glue gun 433 by a threaded connection, and the glue gun 433 is connected to the fixed plate 431 by a screw; the upper end of the connecting plate 436 is connected to the side of the glue brush head 434 by a flexible connecting piece 4361, and the lower end of the connecting plate 436 is fixedly connected to the side of the glue gun fixed head 4311 by a locking screw 4362.

[0051] For details, please refer to Figure 4-7 The flexible connecting piece 4361 includes an elastic top screw 43611, a top screw adjustment nut 43612 and a first spring 43613; a connecting hole is provided on the side of the rubber brush head 434, and a through hole is provided at a position corresponding to the connecting hole of the connecting plate 436. The inner end of the elastic top screw 43611 passes through the through hole and is connected to the connecting hole. The first spring 43613 is sleeved on the elastic top screw 43611 and is located between the connecting plate 436 and the rubber brush head 434. The top screw adjustment nut 43612 is sleeved on the elastic top screw 43611 to lock the connecting plate 436. The connecting plate 436 can support the rubber brush head 434. In addition, since the connecting plate 436 is connected to the side of the rubber brush head 434 through the flexible connecting piece 4361, the rubber brush head 434 can move left and right relative to the connecting plate 436 (but the degree of movement is limited, after all, it is locked to a certain extent by the top screw nut 43612). Of course, the range of movement of the rubber brush head 434 can be controlled by adjusting the tightness of the top screw nut 43612. In order to facilitate the connection of the connecting plate 436, the side where the rubber brush head 434 is connected to the connecting plate 436 is a plane, and a limiting protrusion is horizontally extended outward on the plane, and the limiting protrusion is located above the top of the connecting plate 436, and a movable space is reserved between the limiting protrusion and the top of the connecting plate 436. The role of the limiting protrusion is to control the movement of the glue brush head 434 within a certain range. The reserved interactive space is to give the glue brush head 434 a certain range of movement. If the movement space is not reserved, the glue brush head 434 will not be able to move left and right due to the existence of the limiting protrusion.

[0052] In some embodiments, such as this embodiment, please refer to Figure 4-7, a sliding assembly is provided between the glue gun 433 and the fixed plate 431 for driving the glue gun 433 to move relative to the fixed plate 431; the sliding assembly includes a glue gun fixed block 432, a slider 437 and a guide rail provided on the fixed plate 431; the glue gun 433 is fixed to the glue gun fixed block 432, the glue gun fixed block 432 is connected to the slider 437, and the slider 437 is slidably connected to the guide rail. In this embodiment, the guide rail and the fixed plate 431 are an integrated molding structure. Due to the design of the sliding assembly, it is convenient to realize the flexible movement of the glue gun 433. In this embodiment, the power for the movement of the slider 437 is provided by a motor, and of course in other embodiments, the power can also be provided by other power parts such as a cylinder. Furthermore, in order to achieve the function of flexible adjustment of the glue gun 433 in the up and down direction, the flexible glue brushing mechanism 4 also includes a flexible limiter; the flexible limiter includes a baffle 4311, an adjusting bolt 4312 and a second spring 4313; the baffle 4311 is fixedly connected to the end of the fixing plate 431, a threaded hole is provided on the baffle 4311, the inner end of the adjusting bolt 4312 passes through the threaded hole and stays on the inner side of the baffle 4311, the second spring 4313 is sleeved on the inner end of the adjusting bolt 4312, and one end of the second spring 4313 abuts against the inner side of the baffle 4311, and the other end abuts against the end face of the glue gun fixing block 432. By manipulating the adjusting bolt 4312, the flexibility of the glue gun 433 moving up and down can be adjusted.

[0053] For further information, please refer to Figure 8-14 The device also includes a glue-raising mechanism 6; the glue-raising mechanism 6 includes a box body 61, a first water-absorbing member and a second water-absorbing member; in this embodiment, the first water-absorbing member is a cotton thread 65, and the second water-absorbing member is a sponge 64. Of course, in other embodiments, the first water-absorbing member and the second water-absorbing member can also be other materials with water-absorbing function; the box body 61 is provided with an anti-glue curing liquid storage bin 613 and an anti-glue curing bin 614; the sponge 64 is placed in the anti-glue curing bin 614, and a channel for the cotton thread 65 to pass through is provided between the anti-glue curing liquid storage bin 613 and the anti-glue curing bin 614, one end of the cotton thread 65 is placed in the anti-glue curing liquid storage bin 613, and the other end is coiled above the sponge 64, the box The body 61 is provided with a receiving groove for accommodating the glue brush head 434 of the glue gun 433 at the bottom of the anti-glue curing chamber 614, and the bottom of the receiving groove is communicated with the anti-glue curing chamber 614. When the glue brush head 434 of the glue gun 433 is placed in the receiving groove, the anti-glue curing liquid in the anti-glue curing liquid storage chamber 613 is attracted to the sponge 64 to saturate it by the siphon principle of the cotton thread 65. The top surface of the glue brush head 434 of the glue gun 433 is controlled within a certain distance range from the sponge 64. Therefore, the saturated sponge 64 evaporates the anti-glue curing liquid to the glue brush head 434 of the glue gun 433 to moisten it, thereby preventing the glue brush head 434 of the glue gun 433 from being fixed when not in use.

[0054] Further, the box body 61 includes a main body 611 and an extension 612; the extension 612 is fixed to the side of the upper end of the main body 611; the main body 611 is provided with a main body 611 groove 6111 with an opening direction facing upward, the top of the main body 611 is fixedly connected with a fixed cover plate 62 for sealing the main body 611 groove 6111 so that it forms an anti-glue curing liquid storage bin 613, the extension 612 is provided with an extension 612 groove 6121 with an opening direction facing downward, and the bottom of the extension 612 is fixedly connected with a sealing plate 63 for sealing the extension 612 groove 6121 so that it forms an anti-glue curing bin 614. The side of the main body 611 is provided with an injection hole 6112 for injecting anti-glue curing liquid into the anti-glue curing liquid storage bin 613, and the injection hole 6112 is sealed with a plugging wire 67. In this embodiment, the injection hole 6112 is close to the top of the main body 611.

[0055] In this embodiment, the receiving groove is provided on the sealing plate 63, and a sealing ring 66 for the glue brush head 434 of the sealing glue gun 433 is built into the receiving groove. The provided sealing ring 66 can seal the glue brush head 434 of the glue gun 433 placed in the receiving groove to prevent the anti-glue curing liquid in the anti-glue curing chamber 614 from volatilizing. In addition, a locking port 661 is provided at the top of the sealing ring 66, and the diameter of the locking port 661 is smaller than the diameter of the top end surface of the glue brush head 434 of the sealing glue gun 433. Such a design can prevent the top end surface of the glue brush head 434 of the glue gun 433 from directly contacting the sponge 64, and prevent the sponge 64 from being adhered to glue. Specifically, when the glue brush head 434 of the glue gun 433 is placed in the receiving groove, the spacing distance between the top end surface of the glue brush head 434 of the glue gun 433 and the bottom of the second water absorbing member is 0.5-20 mm. It should be noted that the spacing distance should not be too large. If it is too large, the anti-glue curing liquid will evaporate to the glue brush head 434 of the glue gun 433, which will not have an ideal effect.

[0056] It should be noted that the first suction fixing plate 22, the second suction fixing plate and the third suction fixing plate 73 realize suction fixation of the upper surface through the suction fans respectively arranged thereon. Suction holes are provided on the three suction fixing plates. The suction fans are installed below the suction ports. The upper surface can be sucked by turning on the suction fans to prevent the upper surface from shaking on the suction fixing plates.

[0057] In addition, it should be noted that the coordinated work and control of various mechanisms are centrally controlled through the controller 8. Since the coordinated work and control of various mechanisms through the controller 8 is a commonly used technical means in automation equipment, it will not be elaborated here how the controller 8 achieves centralized control.
