Description

Technical Field

[0001] The invention relates to the technical field of shoe production, and in particular to a shoe production line and a production process. Background Art

[0002] There are two main traditional shoemaking methods: one is injection molding and the other is cold gluing. In cold gluing, the upper is glued to the sole after heating, and then cooled to shape. Compared with injection molding shoes, cold gluing shoes are more comfortable to wear. With the continuous development of the economy, the production equipment and technology of cold gluing shoes are also constantly improving, but there are still some defects.

[0003] For example, Chinese patent CN111264978A discloses a new type of shoemaking assembly line, which belongs to the field of shoemaking production technology, including a steam softening device, a first heat setting machine, a drying device, an upper pressing device, a glue repairing device, a bottom pressing device, a wrinkle removal device, a first freezing setting machine and a shoe last removal device arranged in a U shape, and its shoemaking process includes: upper setting, upper freezing setting, bottom sticking and drying, upper pressing, glue repairing, bottom pressing, wrinkle removal, shoe freezing setting, shoe last removal, and packaging assembly line packaging process. The shoemaking assembly line disclosed in the prior art still requires a lot of manpower, and the overall assembly line is long. Another example is the production line disclosed in Chinese patent CN110693136A, which mainly functions to realize the spraying, brushing and baking of the upper on one device, so that the synchronization efficiency of the upper and the sole is high, and the space utilization rate of the whole line can be improved. However, the setting of the production line cannot guarantee that the work can be operated more continuously and efficiently.

[0056] The first baking mechanism 13 is arranged in the first baking area. Figure 1 and Figure 5 As shown, the first baking mechanism 13 can be specifically arranged on the long side or short side of the rotary spraying line device 1. Specifically, both ends of the first baking mechanism 13 have openings, and the upper end thereof has an opening 131. The first heating tube 132 is fixedly installed inside the first baking mechanism 13.

[0057] The second baking mechanism 14 is arranged in the second baking area, and the second baking mechanism 14 also has an open structure at both ends. Specifically, the second baking mechanism 14 includes an upper baking chamber 141 and a lower baking chamber 142 which are distributed up and down. Second heating tubes 143 are respectively installed in the upper baking chamber 141 and the lower baking chamber 142, and a partition plate 144 is provided between the upper baking chamber 141 and the lower baking chamber 142. A channel groove 145 is formed between the partition plate 144 and the inner wall of one side of the second baking mechanism 14 close to the rotary transport mechanism 12.

[0058] The second heating tube 143 located in the upper baking chamber 141 and the second heating tube 143 located in the lower baking chamber 142 are controlled by different controllers respectively, which can ensure that different drying temperatures can be set between the upper and lower baking chambers. The upper baking chamber 141 is used to bake the soles, and the lower baking chamber 142 is used to bake the uppers.

[0059] A sole pressing device 2 and a freezing and vulcanizing device 3 are arranged at the starting point or the end point of the rotary spraying line device 1, and a steaming device 4 for steaming the shoe upper is arranged at the feeding side of the freezing and vulcanizing device.

[0060] It should be specifically explained that the rotary transfer mechanism 12 includes a rectangular working plate 121 horizontally fixed on the frame 11 and with an arc chamfer. A linear guide 1211 is fixedly connected to the straight side wall of the rectangular working plate 121, and an arc guide 1212 is fixedly connected to the arc chamfered side wall. A plurality of linear guides 1211 and a plurality of arc guides 1212 are interconnected to form an annular guide. A tray structure 122 that can simultaneously carry the sole and the shoe last is slidably connected to the annular guide. The rectangular working plate 121 is provided with a driving structure for driving the tray structure 122 to slide along the annular guide. The driving structure includes a multi-section driving section 123 distributed in an annular manner on the edge of the rectangular working plate 121, and each section of the driving section 123 is respectively controlled by an independent servo motor 124, thereby achieving speed regulation of different working areas.

[0061] The rectangular working plate 121 is provided with a blocking structure 125 at the spraying area or the glue brushing area, and the tray structure 122 is intercepted by the blocking structure 125 .

[0062] At least one driving section 123 is arranged on each straight line side of the rectangular working plate 121, and each driving section 123 includes a synchronous belt 1231, and a main pulley 1232 and a slave pulley 1233 respectively connected to both ends of the synchronous belt 1231. The driving shaft of the servo motor 124 drives the main pulley 1232 to rotate, thereby driving the synchronous belt 1231 to move to realize the transportation of the pallet structure 122. The synchronous belt 1231 adopts a high temperature wear-resistant synchronous belt to drive the pallet structure 122 to perform a cyclic operation.

[0063] The driving section 123 located at the arc chamfer position of the rectangular working plate 121 includes a disc 1234, the bottom surface of the disc 1234 and the bottom surface of the synchronous belt 1231 are on the same horizontal plane, and the disc 1234 is driven to rotate by an independent servo motor 124 to realize the turning movement of the tray structure 122.

[0064] The structural setting of the rotary transfer mechanism 12 can drive the shoe last to circulate, ensuring that the automatic spraying mechanism 15 is seamlessly connected during the spraying process, while also avoiding the repeated back and forth transportation of the shoe last, thereby improving the smoothness of the entire assembly line and high work efficiency.

[0066] The inner end of the connection body 1221 is provided with a positioning block 1225, and the positioning block 1225 is connected with an elastic abutting structure 1226 abutting against the driving section 123, and the elastic abutting structure 1226 includes a rubber block 1227 in contact with the driving section 123, and a supporting block 1228 is embedded in the rubber block 1227, and the rubber block 1227 is connected to the positioning block 1225 through a plurality of spring columns 1229. When the servo motor 124 controls the driving section 124 to move, the connection body 1221 is driven to move, thereby realizing the sliding of the connection body 1221 on the annular guide rail.

[0067] It should be specifically explained that the blocking structure 125 includes a connecting rod assembly and a cylinder 1251 that drives the connecting rod assembly to move. The connecting rod assembly specifically includes a rotatable horizontal axis 1252, a first connecting rod 1253 with one end fixed on the horizontal axis 1252, and a second connecting rod 1254. In the initial state, the first connecting rod 1253 extends vertically downward and has a block 1255 at its lower end. The other end of the second connecting rod 1254 is fixedly connected to the cylinder 1251.

[0068] The tray structure 122 is provided with a limiting groove 1230 that cooperates with the clamping block 1255. Specifically, the limiting groove 1231 is arranged at the inner side end of the positioning block 1225. The cylinder 1251 is extended and retracted to change the angle of the second connecting rod 1254, thereby driving the horizontal shaft 1252 to rotate and change the angle of the first connecting rod 1253, so that the clamping block 1255 is clamped into the limiting groove 1230 or disengaged from the limiting groove 1230.

[0069] It should be specifically explained that the shoemaking production line proposed in the present application also includes a rotary rack device 5, and at least two rotary rack devices 5 are arranged, one of which is arranged in the working area of ​​the steaming device 4 for placing the upper material, and the other rotary rack device 5 is arranged next to the glue brushing area for placing the sole material.

During use, uppers or soles of the same size can be placed on different placement areas 55 respectively, avoiding the problem of confusing the styles of uppers and soles in production, ensuring the matching of uppers and uppers and soles, and thus making the assembly line run more efficiently and orderly, and improving production output. When placing, you can place them in a fixed order, or you can set an identification label on each placement area to facilitate quick identification of the materials placed in each placement area and improve efficiency.

[0071] The isolation net 54 is a metal isolation net, a glass isolation net or a plastic isolation net, which can be selected according to actual needs. In addition, the isolation net 54 can be a mesh or a plate.

[0072] The divider 58 is a one-eighth divider. The specific selection of the divider 58 can be determined according to the number of divisions of the placement area 55 in a layer of the material support platform 53. The setting of the divider 58 can ensure that the material speed is moderate and the parking position is accurate.

[0073] When in use, uppers or soles of different sizes of the same / different styles of shoes are placed in different placement areas 55 of the material support table 53 as required. During the operation of the device, the asynchronous motor 60 provides sufficient power to drive the input shaft of the divider 58 to rotate and complete the indexing work. Then the output shaft of the divider 58 drives the rotating shaft 52 to rotate through the sprocket 57, and finally the upper or sole material to be used is rotated in front of the staff.
