[0021] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] The material transfer system provided by this invention is used for transferring materials and recovering pallets loaded with materials. The materials can be stacked metal sheets, such as aluminum sheets or steel sheets, and can be moved to the material transfer device via forklifts or robotic arms. After the materials are transferred, subsequent operations can include stamping, laser cutting, etc.

[0023] like Figure 1-16 The diagram shown is a schematic representation of an embodiment of the material preparation and transfer system provided by the present invention.

[0024] Please refer to Figure 1-16 This embodiment includes a material transfer device 100, a first guide rail 200, a pallet 300, a pallet recycling device 400, and a carrying trolley 420. The pallet 300 is used to hold materials. The material transfer device 100 is located on the side of the first guide rail 200 and is used to transfer the pallet 300 to the carrying trolley 420. The pallet recycling device 400 is located at the end of the first guide rail 200 and is used to recycle pallets 300 without materials. The first end of the first guide rail 200 is connected to a feeding assembly. The carrying trolley 420 is located on the first guide rail 200 and moves along the first guide rail 200. The carrying trolley 420 is used to carry the pallet 300 or the pallet 300 and its materials.

[0025] In one embodiment, the carrying trolley 420 moves along the first guide rail 200 to the corresponding position of the material transfer device 100, which then moves the pallet 300 carrying the material to the carrying trolley 420. The carrying trolley 420, loaded with the pallet 300 and the material, moves along the first guide rail 200 to the loading assembly (not shown) for unloading. After unloading, the carrying trolley 420, loaded with the empty pallet 300, moves to the pallet recycling device 400, which separates the pallet 300 from the carrying trolley 420 and recycles it. This completes the material transfer and pallet recycling.

[0026] In one embodiment, such as Figure 3-9 As shown, the material preparation and transfer device 100 includes a first moving component 110, a second moving component 120, a third moving component 130, and a carrying component 140. The second moving component 120 and the third moving component 130 are located on the carrying component 140. The first moving component 110 is connected to the carrying component 140 and drives the carrying component 140 to move, specifically moving it closer to or away from the second guide rail. The second moving component 120 includes a conveyor belt 121, located on the carrying component 140. The conveyor belt 121 carries and transports the prepared material, specifically moving the pallet carrying the prepared material onto the carrying trolley on the second guide rail. The third moving component 130 includes a pusher block 131, located on the carrying component 140. The pusher block 131 pushes the pallet 300 carrying the prepared material, specifically pushing the entire pallet 300 onto the carrying trolley 420, thus separating the pallet 300 from the conveyor belt 121.

[0027] The first moving component 110 moves the carrying component 140 closer to the first guide rail 200, positioning the pallet 300 at the edge of the first guide rail 200, thus connecting the conveyor belt 121 with the carrying space of the carrying trolley 420. The conveyor belt 121 transports a portion of the pallet 300 into the carrying space of the carrying trolley 420. The pushing block 131 pushes the pallet 300 completely into the carrying space of the carrying trolley 420, separating the pallet 300 from the material transfer device 100.

[0028] 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. The sliders 143 are connected below the first support plate 141, and the sliders 143 are matched and connected to the first guide rail 111 in the first moving assembly 110. A conveyor belt 121 and a pusher block 131 are disposed on the second support plate 142. Side baffles 144 are provided on both sides of the second support plate 142.

[0029] The first support plate 141 and the second support plate 142 can be rectangular. The number of sliders 143 is four, distributed at the four corners, with two sliders 143 on each side that are matched and connected to the single-sided track of the first guide rail 111. The side baffles 144 are used for limiting the pallet 300 and the two sides of the material preparation area.

[0030] The material preparation and transfer device 100 also includes a rotating assembly 150, which is located between the first support plate 141 and the second support plate 142, and is fixedly connected to the first support plate 141. The rotating assembly 150 drives the second support plate 142 to rotate, which in turn drives the conveyor belt 121 and the push block 131 located on the second support plate 142 to rotate together. The rotating assembly 150 can adjust the receiving direction of the conveyor belt 121 according to the incoming material direction, making the receiving direction more flexible. After receiving the material, the material preparation and transfer direction is adjusted by the rotating assembly 150.

[0031] The rotating assembly 150 includes a gear ring 151, a drive gear 152, a bearing 153, and a first motor 154. The gear ring 151, drive gear 152, and bearing 153 are located between a first support plate 141 and a second support plate 142. The first motor 154 is mounted on the second support plate 142. The gear ring 151 is sleeved on the outside of the bearing 153, and its upper end face is fixedly connected to the lower side of the second support plate 142, causing the second support plate 142 to rotate together with the gear ring 151. The bearing 153 is mounted on the first support plate 141, the drive gear 152 meshes with the gear ring 151, and the output end of the first motor 154 passes through the second support plate 142 and connects to the drive gear 152, driving the drive gear 152 to rotate.

[0032] The first motor 154 drives the drive gear 152 to rotate. The drive gear 152 meshes with the gear ring 151, thereby driving the gear ring 151 to rotate around the bearing 153. Since the gear 151 is fixedly connected to the second support plate 142, it drives the second support plate 142 and the various components provided on the second support plate 142 to rotate accordingly.

[0033] The first moving assembly 110 includes a second guide rail 111, a base 112, and a sliding cylinder 113. The second guide rail 111 and the sliding cylinder 113 are disposed on the base 112, and a first support plate 141 is disposed on the second guide rail 111. The slider 143 of the first support plate 141 is matched and connected to the second 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 direction of the second guide rail 111.

[0034] The base 112 is fixedly connected to the horizontal plane. The setting direction of the second guide rail 111 is perpendicular to the setting direction of the first guide rail 200. The extension end of the sliding cylinder 113 is connected to the far side of the first bearing plate 141. When the sliding cylinder 113 extends to its maximum stroke, the first bearing plate 141 is located at the beginning of the second guide rail 111, away from the first guide rail 200. When the sliding cylinder 113 retracts to its shortest stroke, the first bearing plate 141 is located at the end of the second guide rail 111, close to the first guide rail 200. The conveyor belt 121 on the second bearing plate 142 is connected to the carrying trolley, and the conveyor belt 121 and the roller row 422 of the carrying trolley 420 are in the same straight line.

[0035] The second moving component 120 also includes a second motor 122 and a sprocket drive belt 123. The conveyor belt 121 includes a chain 1211 and sprockets 1212, with the chain 1211 wound around the two sprockets 1212. The second motor 122 is mounted on the second support plate 142, and its output end is connected to the sprocket drive belt 123, driving the sprocket drive belt 123 to rotate. The sprocket drive belt 123 is linked to the sprockets 1212, driving the sprockets 1212 to rotate.

[0036] The direction of movement of chain 1211 is parallel to the direction of the first moving component 110, that is, the direction of movement of chain 1211 is parallel to the setting direction of the second guide rail 111 and perpendicular to the setting direction of the first guide rail 200.

[0037] 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 pallet 300, driving the pallet 300 and the materials carried by the pallet 300 to move into the carrying trolley 420.

[0038] The third moving device 130 includes a material pulling cylinder 132, which is located on the second support plate 142. The telescopic end of the material pulling cylinder 132 is connected to the push block 131. The material pulling cylinder 132 pulls the push block 131 to move. The moving direction of the push block 131 is parallel to the moving direction of the first moving component 110. When the push block 131 pushes the material preparation, it extends from the upper surface of the chain 1211.

[0039] The conveyor belt 121 is used to move the prepared material onto the carrying trolley 420 of the first guide rail 200. However, the power of the conveyor belt 121 is limited. As more of the prepared material moves onto the carrying trolley, the contact area between the conveyor belt 121 and the prepared material becomes smaller, and the conveying power received by the prepared material also decreases, making it difficult to completely transfer the prepared material to the carrying trolley. Therefore, when the conveyor belt power is insufficient, the material pulling cylinder 132 of the third moving device 130 needs to pull the push block 131 to push the prepared material, so as to completely transfer the prepared material located in the area of ​​the conveyor belt 121 to the carrying trolley 420.

[0040] The push block 131 includes a push block 1311, a spring 1312, and a fixed base 1313. The push block 1311 is hinged to the fixed base 1313. One end of the spring 1312 is connected to the push block 1311, and the other end is connected to the fixed base 1313. The fixed base 1313 is connected to the telescopic end of the material pulling cylinder 132. The push block 1311 has an inclined surface a, a limiting surface b, and a pushing surface c. When the push block 1311 pushes the material, the pushing surface c contacts the tray 300 that carries the material, and the limiting surface b is in contact with the surface of the fixed base 1313. The inclined surface a faces the material feeding direction.

[0041] When the upper side or inclined surface a of push block 1311 is subjected to pressure, push block 1311 rotates around the hinge point, causing push surface c to rotate below the upper surface of chain 1211. Push block 1311 stretches spring 1312, and the limiting surface b is set at an angle to the surface of fixed seat 1313. When the pressure on the upper side or inclined surface a of push block 1311 is removed, spring 1312 retracts, pulling push block 1311 back to its original position, causing push surface c to extend out of the upper surface of chain 1211, and limiting surface b is in contact with the surface of fixed seat 1313. The angle between limiting surface b and the surface of fixed seat 1313 limits the rotation range of push block 1311. Limiting surface b limits the rotation direction of push block 1311.

[0042] The moving range of the material-pulling cylinder 132 pushing the pusher block 131 is from the middle to the end of the chain 1211. After the conveyor belt 121 conveys the prepared material to the middle of the chain 1211 and past the pusher block 1311, the pusher block 1311 provides additional power, pushing the pallet 300 and its prepared material to continue moving along the chain 1211 and completely transfer them to the carrying trolley.

[0043] The springback design of this pusher block 1311 is located below the chain 1211 when the conveyor belt 121 is conveying the material preparation, and does not interfere with the movement of the conveyor belt 121. When the conveyor belt 121 conveys the material preparation distance beyond the pusher block 1311, the pusher block 1311 springs back under the action of elasticity and pops out from below the chain 1211, pushing the edge of the material preparation and continuing to drive the material preparation to move completely to the carrying trolley.

[0044] The working process of the material transfer device 100 is as follows: The initial position is that the carrying component 140 is at the beginning of the second guide rail 111. The rotating component 150 drives the conveyor belt 121 to rotate to adapt to the incoming material direction. The pallet loaded with the material is transferred onto the conveyor belt 121 by a forklift. Then, the rotating component 150 drives the conveyor belt 121 to rotate perpendicular to the first guide rail 200. The sliding cylinder 113 pulls the carrying component 140 from the beginning to the end of the second guide rail 111. The conveyor belt 121 is connected to the roller row of the carrying trolley. The operation of the conveyor belt 121 drives the pallet and the material to move into the 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 to push the pallet and the material to be completely transferred to the carrying trolley along the conveyor belt. After the transfer, the material pulling cylinder 132 drives the push block 1311 back to its original central position, and the sliding cylinder 113 drives the bearing assembly 140 back to the beginning of the second guide rail 111. The above process is repeated to achieve continuous transfer of the prepared material between the bearing trolleys.

[0045] In one embodiment, the carrying trolley 420 includes a carrying frame 421, a roller row 422, and a roller assembly 423. The carrying frame 421 is hollow inside. The roller row 422 is located on the upper side of the carrying frame 421. When the carrying trolley 420 carries the pallet 300, the pallet 300 rolls in contact with the roller row 422. When the carrying trolley 420 moves to the material transfer device 100 to receive the material, the roller row 422 and the chain 1211 in the material transfer device 100 are in the same straight line (i.e., the setting direction of the roller row 422 is parallel to the moving direction of the conveyor belt 121 in the material transfer device 100 that transports the pallet 300). The roller assembly 423 is located on the lower side of the carrying frame 421 and rolls in contact with the first guide rail 200. The roller assembly 423 drives the carrying frame 421 to move along the first guide rail 200.

[0046] The roller row 422 includes multiple rollers arranged in sequence to reduce the friction when the pallet 300 moves on the carrying trolley 420. There are multiple roller rows 422, and they are arranged in parallel.

[0047] The roller assembly 423 includes a drive motor 4231, a motor drive belt 4232, two drive wheels 4233, and multiple driven wheels 4234. The drive motor 4231 is mounted on the support frame 421 and is powered by the motor drive belt 4232, which is powered by the drive wheels 4233. The two drive wheels 4233 are linked by a linkage shaft. The two drive wheels 4233 and the multiple driven wheels 4234 are distributed on both sides of the lower side of the support frame 421, contacting the first guide rail 200. The roller assembly 423 drives the carrying trolley 420 to move along the first guide rail 200. In addition, the carrying trolley 420 includes baffles 424, which are located on both sides of the support frame 421 and parallel to the direction of the roller row 422. The baffles 424 are used to limit the movement of the pallet 300 on both sides.

[0048] In one embodiment, such as Figure 10-16 As shown, the pallet recycling device 400 includes a frame 410 and a lifting assembly 430. The frame 410 is divided into upper and lower areas: the lower area is the recycling area 411, and the upper area is the storage area 412. The recycling area 411 and the storage area 412 are connected. The storage area 412 is used to store multiple stacked pallets 300, and the stacked pallets 300 are removed through the outlet of the storage area 412. A first guide rail 200 covers the interior of the recycling area 411, which is used to accommodate a carrying trolley 420. The carrying trolley 420 carries the pallets 300 and moves them through the inlet of the recycling area 411 into the interior of the recycling area 411. In this embodiment, the direction of the inlet of the recycling area 411 is perpendicular to the direction of the outlet of the storage area 412.

[0049] The lifting assembly 430 is located on the frame 410, below the recycling area 411, and is used to lift and separate the pallet 300 from the carrying trolley 420, and move the pallet 300 from below the storage area 412 to the inside of the storage area 412, so as to realize the recycling and collection of the pallet 300.

[0050] Vertical limiting rods 413 are provided on both sides of the outlet direction of the storage area 412. The limiting rods 413 are fixedly connected to the frame 410 and are used to limit the sides of the tray 300. A receiving shaft 414 is provided at the bottom of the limiting rods 413, supporting the bottom of the tray 300. The receiving shafts 414 are distributed at the four corners of the bottom of the storage area 412. There are four limiting rods 413, two on each side, used to limit the sides of the tray 300. The receiving shafts 414 support the bottom of the tray 300, confining the tray 300 within the storage area 412.

[0051] During the process of the lifting component 430 moving the pallet 300 from the recycling area 411 to the storage area 412, the top of the pallet 300 contacts the receiving shaft 414, causing the receiving shaft 414 to flip upwards, and the pallet 300 enters the storage area 412. When the pallet 300 is lifted by the lifting component 430 to a height higher than the receiving shaft 414, the lifting component 430 returns to its original position, and the bottom of the pallet 300 contacts the receiving shaft 414, causing the receiving shaft 414 to flip downwards to a horizontal position. The receiving shaft 414 supports the bottom of the pallet 300, so that the pallet 300 is located within the storage area 412.

[0052] Specifically, the receiving shaft 414 includes a connecting seat 4141, a connecting shaft 4142, and a rotating surface 4143. One end of the connecting shaft 4142 is hinged to the connecting seat 4141, and the other end is connected to the rotating surface 4143. The rotating surface 4143 covers the circumference of the connecting shaft 4142 and rotates about the connecting shaft 4142 as its axis. The rotating surface 4143 contacts the tray 300. The connecting seat 4141 is fixedly connected to the frame 110. The hinge point between the connecting shaft 4142 and the connecting seat 4141 has an arc surface 4144 and a flat surface 4145, and the connecting shaft 4142 rotates within the range of the arc surface 4144. The receiving shaft 414 can rotate upward and return to a horizontal position. Figure 15 As shown, when the pallet 300 moves from bottom to top, it contacts the horizontal receiving shaft 414, causing the receiving shaft 414 to rotate upward. The pallet 300 then enters the storage area 412. Afterward, the receiving shaft 414 rotates downward under the gravity of the pallet 300 to return to its original horizontal position, thus supporting the pallet 300.

[0053] During the process of the lifting assembly 430 moving the pallet 300 from the recycling area 411 to the storage area 412, the top of the pallet 300 contacts the rotating surface 4143, causing the connecting shaft 4142 to rotate upwards, and the flat surface 4145 to separate from the surface of the connecting seat 4141. When the pallet 300 is lifted by the lifting assembly 430 to a height higher than the receiving shaft 414, the downward pressure of the pallet causes the lifting assembly 430 to return to its original position, and the bottom of the pallet 300 contacts the rotating surface 4143, causing the connecting shaft 4142 to rotate downwards. The receiving shaft 414 supports the bottom of the pallet 300, the flat surface 4145 is in contact with the surface of the connecting seat 4141, and the connecting shaft 4142 is in a horizontal position.

[0054] In addition, when the receiving shaft 414 is in a horizontal state, it is perpendicular to the outlet direction of the storage area 412. When the stacked pallets 300 move along the outlet direction, they come into contact with the rotating surface 4143 of the receiving shaft 414 in a rolling contact manner, which can reduce the friction of the pallet 300 movement.

[0055] The lifting assembly 430 includes a first push plate 431 and a lifting cylinder 432. The telescopic end of the lifting cylinder 432 is connected to the first push plate 431. The lifting cylinder 432 drives the first push plate 431 to move from below the recycling area 411 towards the storage area 412. During the movement, it passes through the hollow area of ​​the support frame 421, lifting the pallet 300 carried by the support trolley 420, separating the pallet 300 from the support trolley 420, and lifting the pallet 300 into the storage area 412. In this embodiment, there are two lifting cylinders 432 and two first push plates 431.

[0056] The pallet recycling device 400 also includes an adjusting cylinder 440. One adjusting cylinder 440 is installed in the recycling area 411 and one in the storage area 412. The telescopic end of the adjusting cylinder 440 is connected to a second push plate 441. The adjusting cylinder 440 drives the second push plate 441 to push the pallet 300, adjusting the position of the pallet 300 in the recycling area 411 and the storage area 412, or providing compensating power for the horizontal movement of the pallet 300.

[0057] In one embodiment, the pallet 300 includes a bottom frame 310 and a plurality of support crossbars 320. The bottom frame 310 has a hollow structure, which facilitates the unloading assembly to lift the material from below the pallet 300 for loading. The support crossbars 320 are located on the upper side of the bottom frame 310 and are fixedly connected to the bottom frame 310. The plurality of support crossbars 320 are spaced apart, and a notch 311 is provided on the lower side of the bottom frame 310.

[0059] Specifically, a forklift can be used to transfer the pallet and its contents to the material transfer device, with the first position located at the beginning of the second guide rail.

[0060] S200, the material preparation and transfer device moves to the second position, the carrying trolley moves to the third position, and the material preparation and transfer device moves the material and pallet to the carrying trolley.

[0061] The second position refers to the end of the second guide rail, and the third position is located on the first guide rail. At this time, the carrying space of the trolley is connected to the carrying space of the material transfer device.

[0062] The S300, carrying trolley, transports the materials and pallets to the fourth position to complete the material preparation and unloading.

[0063] The fourth position is the beginning of the first guide rail, where a feeding component, a distributing component, or other operating components are installed.
