DETAILED DESCRIPTION

[0020] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] The following describes the plate edge banding reversing device according to an embodiment of the present application with reference to the accompanying drawings.

[0022] like Figure 1-Figure 7 As shown, the plate edge banding reversing device of the embodiment of the present application may include a base 10 and a transfer mechanism 20, a limiting module 30 and a positioning arm 40 sequentially arranged on the base 10.

[0023] The transfer mechanism 20 may include a transfer frame 21, a receiving tray 22, an attracting member 23, and a conveying unit (not shown in the figure), wherein the transfer frame 21 is movably disposed on the base 10 via a moving member 11. The receiving tray 22 is movably disposed above the transfer frame 21 via a rotating member 12.

[0024] It should be noted that the moving component 11 described in this embodiment has the function of controlling the linear movement of the transfer rack 21 on the base 10. The moving component 11 can be a cylinder, a slide module, etc. The moving component 11 can drive the transfer rack 21 to transfer the plate 80 on the receiving tray 22 to the positioning arm 40. In conjunction with the positioning module 41, the plate 80 can be accurately loaded. The rotating component 12 described in the embodiment of the present application has the function of controlling the rotation of the receiving tray 22 relative to the transfer rack 21. The rotating component 12 can use a rotating motor, and the rotating component 12 can drive the receiving tray 22 and the plate 80 on the receiving tray 22 to perform a reversing operation. The moving component 11 and the rotating part are both existing technologies and will not be described in detail here.

[0025] The suction member 23 and the conveying unit are both arranged on the top surface of the receiving tray 22, wherein the suction member 23 may include a mounting seat 232, a lifting frame 233 and a plurality of suction cylinders 231, wherein the top opening edge of each suction cylinder 231 is provided with a sealing ring 2311, and the bottom opening is connected to a branch conduit 51, and the plurality of branch conduits 51 are connected to the same main conduit 52, and the mounting seat 232 is provided with a guide mesh 2321 for accommodating the branch conduits 51 and the main conduit 52, and the input end of the main conduit 52 is provided through the mounting seat 232. The mounting seat 232 is detachable and is arranged on the top surface of the receiving tray 22, and the plurality of suction cylinders 231 are arranged in sequence along the direction of the mounting seat 232. The lifting frame 233 is arranged on the mounting seat 232 through the lifting member 14, and the lifting frame 233 is provided with a plurality of through-holes 2331, and the plurality of suction cylinders 231 are respectively provided through the corresponding through-holes 2331. The lifting member 14 described in this embodiment has the function of controlling the vertical movement of the lifting frame 233. The lifting member 14 can be a cylinder or the like.

[0026] It should be noted that the output end of the main duct 52 described in this embodiment is connected to multiple branch ducts 51, and the input end can be connected to an external suction fan. The external suction fan can generate suction to the multiple branch ducts 51 through the main duct 52, and then the branch ducts 51 adsorb the plate 80 through the corresponding suction tubes 231, thereby achieving a firm fixation of the plate 80, and then the plate 80 can be accurately transferred and reversed.

[0027] Under the action of the lifting member 14 , the plurality of suction cylinders 231 described in this embodiment can realize the lifting function. When the suction cylinders 231 move upward, the sealing ring 2311 can fit tightly with the bottom surface of the plate 80 on the receiving tray 22 .

[0028] In addition, when the suction cylinder 231 moves downward, the sealing ring 2311 is separated from the plate 80 , and the sealing ring 2311 is lower than the conveying wheel 241 . At this time, the plate 80 can be smoothly transferred through the multiple conveying wheels 241 .

[0029] The attraction member 23 in the embodiment of the present application is arranged in the middle of the receiving tray 22, and the mounting seat 232 and the lifting frame 233 are both in a matching serpentine shape. Such a design helps to improve the adsorption and positioning effect of the plate 80.

[0030] The conveying unit consists of multiple parallel conveying wheels 241. Each of the conveying wheels 241 is connected to a synchronous drive member 60. The top surface of the receiving tray 22 is formed with multiple grooves 221 and a receiving chamber (not shown) within the receiving tray. The conveying wheels 241 are positioned within corresponding grooves 221. The synchronous drive member 60 in this embodiment controls the synchronous and co-directional rotation of the multiple conveying wheels 241, thereby assisting in the movement and positioning of the sheet material 80 on the receiving tray 22. Specifically, the synchronous drive member 60 includes a motor 61, multiple gear sets 62, and multiple parallel rollers 63. Each gear set 62 includes a meshing master gear 621 and a slave gear 622. The central axis of each conveying wheel 241 extends through the receiving chamber and is connected to the corresponding slave gear 622. The master gear 621 is mounted on the corresponding roller 63. Each roller 63 is movably positioned within the receiving chamber, with one roller 63 connected to the motor 61. The multiple rollers 63 are connected via a linkage 70. It should be noted that the linkage member 70 described in this embodiment has the function of controlling the synchronous and unidirectional rotation of multiple rollers 63. The linkage member 70 can refer to the driving method of the conveyor belt in the prior art. Specifically, the linkage member 70 may include multiple sprockets 71 and chains 72, wherein the sprockets 71 and the rollers 63 correspond one to one, and the multiple sprockets 71 are respectively arranged on the outside of the corresponding rollers 63, and a chain 72 is arranged on the outside of two adjacent sprockets 71.

[0031] It should be noted that the outer side of the conveying wheel 241 described in this embodiment is provided with a friction layer made of rubber, silicone or other materials. This design can enhance the friction force when the conveying wheel 241 is in contact with the plate 80 , thereby facilitating the smooth conveyance of the plate 80 .

[0032] In the embodiment of the present application, the main gear 621, the slave gear 622, and the conveyor wheel 241 correspond one to one. The motor 61 drives the connected roller 63 to rotate. The sprocket 71 on the outer side of the roller 63 drives the meshed chain 72, which in turn drives the other roller 63 on the inner side of the chain 72 to rotate synchronously and in the same direction. The coordinated action of the multiple sprockets 71 and chains 72 enables the multiple rollers 63 to rotate synchronously and in the same direction. Simultaneously, driven by the multiple gear sets 62, the multiple conveyor wheels 241 also rotate synchronously and in the same direction, ensuring smooth conveyance of the sheet 80.

[0033] At least two groups of limiting modules 30 are provided, and each limiting module 30 may include multiple limiting members 31. The limiting members 31 are arranged in at least two parallel rows, and the two rows of limiting members 31 are symmetrically arranged. Each limiting member 31 has a telescopic end, and the height of the telescopic end is higher than the height of the conveying wheel 241. The limiting members 31 described in this embodiment can be vertically arranged gas rods. The output end of the gas rod is the telescopic end. The height of the output end can be flexibly controlled by the gas rod, thereby effectively limiting the position of the plate 80 as it enters the receiving tray 22.

[0034] In the examples of this application, reference is made to Figure 7 The two sets of limiting modules 30 respectively block and limit the plates entering the receiving tray 22 in the horizontal and vertical directions. Each limiting module 30 is equipped with at least two rows of limiting members 31. By selecting two corresponding limiting members 31 located on the same straight line, these limiting members 31 can contact the edges of the plates entering the receiving tray 22, effectively ensuring that the plates are placed correctly and providing a strong guarantee for the precise positioning of the plates.

[0035] One end of the positioning arm 40 extends toward the input end of the edge banding machine 901. A positioning module 41 is provided on one side of the positioning arm 40. The positioning module 41 may include a side wheel 4112 group 411 and two main wheel groups 412 arranged in a V shape, wherein the two main wheel groups 412 are parallel and are respectively connected to the relative drive component 13. The side wheel 4112 group 411 may include a side plate 4111 and a plurality of side wheels 4112 arranged side by side on the side plate 4111. The side plate 4111 is fixed to the positioning arm 40. The main wheel group 412 may include a main plate 4121 and a plurality of main wheels 4122 arranged side by side on the main plate 4121. The relative drive component 13 is provided on the other side of the positioning arm 40, and the output end of the relative drive component 13 is respectively connected to the two main plates 4121. It should be noted that the relative driving component 13 described in this embodiment can be a bidirectional cylinder, and the two output ends of the bidirectional cylinder are respectively connected to the two main boards 4121. By starting the bidirectional cylinder, the two main boards 4121 can be moved relative (closer to each other or away from each other), thereby achieving the clamping and positioning of the plate 80.

[0036] The main wheel assembly 412 is provided with a plurality of avoidance openings 4123 for avoiding the corresponding conveying wheels 241. It is understandable that the conveying wheels 241 that need to be avoided are located at the edge of the receiving tray 22.

[0037] It should be noted that the two ends of the external rotary conveyor production line are respectively located near the exit of the edge banding machine 901 and the other end of the base 10 away from the positioning arm 40. This layout enables the device to smoothly receive the plates 80 output from the rotary conveyor production line and deliver them to the entrance of the edge banding machine 901. At the same time, the device can also perform a direction change operation on the plates 80 during the process of transferring the plates 80.

[0038] Specifically, when it is necessary to load the plate 80 that has completed single-side edge banding, the relevant personnel first adjust the corresponding two limit members 31 (the two limit members 31 are located on the same straight line) according to the different sizes of the plate 80, so that the telescopic end of the adjusted limit member 31 moves up and is higher than the conveying wheel 241.

[0039] Next, the sheet 80 is transported to the receiving tray 22 via an external rotary conveyor belt production line. During this process, personnel control the synchronous rotation of multiple conveyor wheels 241 using the synchronous drive 60 to assist in the transfer of the sheet 80. When one end of the sheet 80 contacts the two stoppers 31, the conveyor wheels 241 stop rotating, completing the transfer of the sheet 80.

[0040] After the sheet 80 is positioned on the receiving tray 22, personnel use the lifting member 14 to control the lifting frame 233 and multiple suction cylinders 231 to move upward, until the suction cylinders 231 are in close contact with the sealing ring 2311 and the bottom surface of the sheet 80 on the receiving tray 22. Next, the external suction fan is activated. The external suction fan generates suction through the main duct 52 on the multiple branch ducts 51. The branch ducts 51 absorb the sheet 80 through the corresponding suction cylinders 231, thereby securing the sheet 80. Subsequently, the receiving tray 22 is driven to rotate 90 degrees by the rotating member 12, completing the reversal of the sheet 80.

[0041] Then, the transfer operation of the plate 80 is carried out. First, the telescopic end of the regulated limiter 31 is moved downward and reset so that the limiter 31 is lower than the transfer rack 21. Then, the transfer rack 21 is driven to move toward the positioning arm 40 by the moving part 11.

[0042] When one side of the plate 80 enters between the upper and lower main wheels 4122 and contacts the side wheel 4112, the relevant personnel immediately control the two main boards 4121 to approach each other through the relative driving component 13, so that the upper and lower main wheels 4122 clamp and position the plate 80.

[0043] Finally, the relevant personnel control the rotation of multiple conveying wheels 241 to accurately transport the plate 80 toward the edge banding machine 901, thereby achieving accurate loading of the plate 80.

[0044] In summary, the plate edge banding reversing device of the embodiment of the present application can realize precise reversing and loading operations of the plate, and can flexibly adapt to the processing scenarios of plates of different sizes, thereby significantly improving the overall efficiency of the plate edge banding operation.
