After the stock is transferred, subsequent operations can include stamping, laser cutting, and other processes.

[0042] like Figure 1-7 , which is a schematic diagram of an embodiment of the material preparation and transfer device provided by the present invention.

[0043] Please refer to Figure 1-7 This embodiment includes a first moving assembly 110 , a second moving assembly 120 , a third moving assembly 130 and a carrying assembly 140 . The second moving assembly 120 and the third moving assembly 130 are disposed on the carrying assembly 140 .

[0044] The first moving assembly 110 is connected to the supporting assembly 140 and drives the supporting assembly 140 to move, specifically, to move the supporting assembly 140 toward or away from the second guide rail. The second moving assembly 120 includes a conveyor belt 121, which is mounted on the supporting assembly 140. The conveyor belt 121 is used to carry and transport the prepared materials. Specifically, the conveyor belt 121 drives the pallet carrying the prepared materials to move onto the carrying trolley on the second guide rail. The third moving assembly 130 includes a push block 131, which is mounted on the supporting assembly 140. The push block 131 is used to push the pallet carrying the prepared materials, specifically, to push the entire pallet 300 onto the carrying trolley, thereby separating the pallet from the conveyor belt 121.

[0045] In one embodiment, the support assembly 140 includes a first support plate 141, a second support plate 142, and a plurality of sliders 143. The second support plate 142 is disposed above and connected to the first support plate 141. Sliders 143 are connected below the first support plate 141 and mate with the first guide rail 111 in the first moving assembly 110. The conveyor belt 121 and the push block 131 are disposed on the second support plate 142. Side guards 144 are provided on both sides of the second support plate 142.

[0046] The first and second carrier plates 141, 142 may be rectangular in shape, and there are four sliders 143 distributed at four corners, with two sliders 143 provided on each side to match and connect with the single-side track of the first guide rail 111. The side guards 144 are used to limit the positions of the tray 300 and the prepared materials.

[0047] In one embodiment, a rotating assembly 150 is positioned between a first carrier plate 141 and a second carrier plate 142 and is fixedly connected to the first carrier plate 141. The rotating assembly 150 drives the second carrier plate 142 to rotate, thereby driving the conveyor belt 121 and the push block 131 located on the second carrier plate 142 to rotate. The rotating assembly 150 can adjust the direction of material delivery from the conveyor belt 121 based on the incoming material direction, providing greater flexibility in material delivery. After receiving the material, the rotating assembly 150 adjusts the direction of material transfer.

[0048] Furthermore, the rotating assembly 150 includes a ring gear 151, a driving gear 152, a bearing 153 and a first motor 154. The ring gear 151, the driving gear 152 and the bearing 153 are located between the first supporting plate 141 and the second supporting plate 142. The first motor 154 is provided on the second supporting plate 142. The ring gear 151 is sleeved on the outside of the bearing 153, and the upper end face of the ring gear 151 is fixedly connected to the lower side of the second supporting plate 142, so that the second supporting plate 142 rotates together with the ring gear 151. The bearing 153 is provided on the first supporting plate 141, and the driving gear 152 is engaged with the ring gear 151. The output end of the first motor 154 passes through the second supporting plate 142 and is connected to the driving gear 152, driving the driving gear 152 to rotate.

[0049] The first motor 154 drives the driving gear 152 to rotate. The driving gear 152 meshes with the ring gear 151, thereby driving the ring gear 151 to rotate around the bearing 153. Since the gear 151 is fixedly connected to the second supporting plate 142, the second supporting plate 142 and various components disposed on the second supporting plate 142 are driven to rotate accordingly.

[0050] In one embodiment, the first moving assembly 110 includes a first guide rail 111, a base 112, and a sliding cylinder 113. The first guide rail 111 and the sliding cylinder 113 are mounted on the base 112. A first support plate 141 is mounted on the first guide rail 111, and a slider 143 of the first support plate 141 is mated and connected to the first guide rail 111. The telescopic end of the sliding cylinder 113 is connected to the first support plate 141, driving the first support plate 141 to move along the first guide rail 111.

[0051] The base 112 is fixedly connected to a horizontal surface. The orientation of the first guide rail 111 and the orientation of the second guide rail 200 are perpendicular to each other. The telescopic end of the sliding cylinder 113 is connected to the far side of the first support plate 141. When the sliding cylinder 113 is extended to its maximum stroke, the first support plate 141 is located at the leading end of the first guide rail 111, away from the second guide rail 200. When the sliding cylinder 113 is retracted to its minimum stroke, the first support plate 141 is located at the trailing end of the first guide rail 111, closer to the second guide rail 200. The conveyor belt 121 on the second support plate 142 is connected to the support trolley, and the roller rows of the conveyor belt 121 and the support trolley are aligned.

[0052] In one embodiment, the second moving assembly 120 further includes a second motor 122 and a sprocket belt 123. The conveyor belt 121 includes a chain 1211 and sprockets 1212, with the chain 1211 wrapped around two sprockets 1212. The second motor 122 is mounted on the second carrier plate 142. The output end of the second motor 122 is connected to the sprocket belt 123, driving the sprocket belt 123 to rotate. The sprocket belt 123 is linked to the sprockets 1212, driving the sprockets 1212 to rotate.

[0053] The moving direction of the chain 1211 is parallel to the direction of the first moving assembly 110 , that is, the moving direction of the chain 1211 is parallel to the setting direction of the first guide rail 111 and perpendicular to the setting direction of the second guide rail 200 .

[0054] There are multiple conveyor belts 121, and the sprockets in the multiple conveyor belts 121 are connected by a linkage shaft 124. In this embodiment, there are four conveyor belts 121, which are arranged in parallel. The conveyor belts 121 contact the bottom of the tray 300, driving the tray 300 and the prepared materials carried by the tray 300 to move to the carrying trolley.

[0055] In one embodiment, the third moving component 130 includes a pulling cylinder 132, which is arranged on the second supporting plate 142. The telescopic end of the pulling cylinder 132 is connected to the pushing block 131. The pulling cylinder 132 pulls the pushing block 131 to move. The moving direction of the pushing block 131 is parallel to the moving direction of the first moving component 110. When the pushing block 131 pushes the preparation material, it extends from the upper surface of the chain 1211.

[0056] The conveyor belt 121 is used to move the stock to the trolley on the second guide rail 200. However, the power of the conveyor belt 121 is limited. As more of the stock moves to the trolley, the contact area between the conveyor belt 121 and the stock decreases, and the conveying power applied to the stock decreases, making it difficult to fully transfer the stock to the trolley. Therefore, if the conveyor belt power is insufficient, the pulling cylinder 132 of the third moving assembly 130 is required to pull the pushing block 131 to push the stock, completely transferring the stock located in the area of ​​the conveyor belt 121 to the trolley.

[0057] Specifically, the push block 131 comprises a push block 1311, a spring 1312, and a fixed seat 1313. The push block 1311 and the fixed seat 1313 are hingedly connected. One end of the spring 1312 is connected to the push block 1311, and the other end is connected to the fixed seat 1313. The fixed seat 1313 is connected to the telescopic end of the pulling cylinder 132. The push block 1311 is provided with an inclined surface a, a limiting surface b, and a push surface c. When the push block 1311 pushes the prepared material, the push surface c contacts the tray 300 carrying the prepared material, while the limiting surface b contacts the surface of the fixed seat 1313.

[0058] like Figure 7As shown, when pressure is applied to the upper side or inclined surface a of push block 1311, push block 1311 rotates about the hinge point, driving push surface c to rotate below the upper surface of chain 1211. Push block 1311 stretches spring 1312, and restricting surface b forms an angle with the surface of fixed seat 1313. When the pressure on the upper side or inclined surface a of push block 1311 disappears, spring 1312 retracts, pulling push block 1311 back to its original position, driving push surface c to extend beyond the upper surface of chain 1211, and restricting surface b to mate with the surface of fixed seat 1313. Inclined surface a faces the direction of incoming material.

[0059] The limiting surface b is set at an angle with the surface of the fixing seat 1313, and the angle setting limits the rotation range of the push block 1311. The limiting surface b limits the rotation direction of the push block 1311.

[0060] Furthermore, the pulling cylinder 132 pushes the push block 131 from the middle to the end of the chain 1211. After the conveyor belt 121 transports the prepared material to the middle of the chain 1211 and exceeds the push block 1311, the push block 1311 replenishes power and pushes the prepared material to continue moving along the chain 1211 and completely transfer it to the carrying trolley.

[0061] The rebound design of this push block 1311 is located under the chain 1211 when the conveyor belt 121 transports the prepared material, and does not interfere with the movement of the conveyor belt 121. When the conveyor belt 121 transports the prepared material a distance exceeding the push block 1311, the push block 1311 rebounds and pops out from under the chain 1211 under the action of elastic force, pushing the edge of the prepared material and continuing to drive the prepared material to move completely to the carrying trolley.

[0062] The transfer process of the material preparation transfer device of this embodiment is as follows:

[0063] The load-carrying assembly 140 is at the head end of the first guide rail 111, its initial position. The rotating assembly 150 drives the conveyor belt 121 to rotate in the direction of incoming materials. A forklift then transfers the loaded pallet of materials onto the conveyor belt 121. The rotating assembly 150 then drives the conveyor belt 121 to rotate perpendicular to the second guide rail 200. The sliding cylinder 113 pulls the load-carrying assembly 140 from the head end of the first guide rail 111 to the tail end. The conveyor belt 121 is now connected to the roller row of the load-carrying trolley. The conveyor belt 121 drives the pallet and the materials into the load-carrying trolley. After moving past the push block 1311, the push block 1311 pops out from under the chain 1211. The pulling cylinder 132 pulls the push block 1311, pushing the pallet and materials along the conveyor belt to complete their transfer to the load-carrying trolley. After the transfer, the pulling cylinder 132 drives the push block 1311 back to its original center position, and the sliding cylinder 113 drives the load-carrying assembly 140 back to the head end of the first guide rail 111. Repeat the above process to achieve continuous transfer of prepared materials.

[0064] like Figure 8As shown, the present invention also provides an embodiment of a prepared material transfer system, which is used to transfer prepared materials and recycle pallets loaded with prepared materials.

[0065] The system comprises the aforementioned stock transfer device 100, as well as a second guide rail 200, a tray 300, a carrying trolley 400, and a tray recovery device 500. The tray 300 is used to hold stock; the stock transfer device 100 is located on the side of the second guide rail 200 and is used to transfer the tray 300 to the carrying trolley 400. The tray recovery device 500 is located at the end of the second guide rail 200 and is used to recover trays 300 without stock. The head end of the second guide rail 200 is connected to the loading assembly. The carrying trolley 400 is located on the second guide rail 200 and moves along the second guide rail 200. The carrying trolley 400 is used to carry the tray 300.

[0066] The material transfer device 100 receives the pallet 300 and the material carried by the pallet 300, and transfers the pallet 300 and the material to the carrying trolley 400 on the second track 200. The carrying trolley 400 loads the pallet 300 and the material to the loading assembly for unloading. After unloading, the carrying trolley 400 carries the pallet 300 and moves to the pallet recovery device 500. The pallet recovery device 500 recovers the pallet, and the carrying trolley 400 moves to the material transfer device 100 to receive the material. The above process is repeated to realize the automated transfer of material and the automated recovery of pallets, maintain stable loading of the automated assembly line, maintain stable production efficiency, and the material transfer process also provides a buffer interval before loading.
