Description

Technical Field

[0001] This utility model relates to the field of plate stacking technology, and in particular to a plate stack top and bottom protection system. Background Technology

[0002] Post-processing of engineered wood panels includes processes such as panel screening, cooling, and stacking. The stacking process involves initially stacking the continuously input panels into a designated height, such as a 1.5m stack, and then transferring this stack to a warehouse for further stacking into larger stacks, such as 6m high, for storage. Engineered wood panels come in varying thicknesses, with thinner panels exhibiting relatively lower strength and weaker resistance to compression and bending. During the transfer process after stacking, neither roller conveyors nor forklift-like lifting mechanisms provide comprehensive support to the bottom of the stack. To prevent deformation of thin panel stacks during transport and subsequent storage, thicker pads need to be placed at both the top and bottom of the stack to provide adequate support. Currently, the post-processing of engineered wood panels has been streamlined, and the processing speed of the panels is very fast. As a result, the stacking process uses a dual-station alternating stacker, such as the stacker disclosed in the utility model patent with announcement number "CN219216787U", to carry out stacking operations. However, there is currently no machinery that can be used to lay the top and bottom pads for this stacker. To solve this problem, the inventor proposed this invention. Utility Model Content

The distribution frame is equipped with a distribution mechanism for distributing the pads at the pad receiving station to the bottom plate distribution station or the top plate distribution station. The bottom plate distribution station is equipped with a bottom plate input machine for inputting pads into the stacking platform. A pallet stack output machine is provided on the side of the stacking platform, and the pallet stack output machine passes through the top plate distribution station.

[0005] As a preferred technical solution, the dispensing mechanism includes a dispensing movable frame that is horizontally movably mounted on the dispensing frame, and a dispensing position control device is provided between the dispensing movable frame and the dispensing frame; a vertically movably mounted pick-and-place frame is mounted on the dispensing movable frame, and a pick-and-place height control device is provided between the pick-and-place frame and the dispensing movable frame; a pick-and-place device is mounted on the pick-and-place frame.

[0006] As a preferred technical solution, the distribution position control device includes two position control sprockets rotatably mounted on the distribution frame, and a position control chain is jointly mounted on the two position control sprockets. At least one link on the position control chain is connected to the distribution movable frame, and one of the position control sprockets is connected to a position control motor.

[0007] As a preferred technical solution, the pick-up and place height control device includes at least three height control pull straps connected to the pick-up and place frame. A height control roller is rotatably installed on the distribution movable frame corresponding to each of the height control pull straps. The upper end of the height control pull strap is wound on the corresponding height control roller, and the height control roller is connected to a height control motor.

[0008] As a preferred technical solution, the pickup / placer includes a pickup / placement suction cup.

[0009] As a preferred technical solution, the base plate input machine includes an input frame, on which a base plate conveying frame for reciprocating movement between the base plate distribution station and the side of the stacking platform is installed, and a traveling device is installed on the base plate conveying frame; a roller input device for inputting pads to the stacking platform is installed on the base plate conveying frame.

[0010] As a preferred technical solution, the pallet output machine includes an output frame, on which a roller conveyor is installed for conveying pallets from the side of the stacking platform to the top plate distribution station. A vertically movable steering conveyor is installed on the output frame at the side of the stacking platform. A plurality of chain conveyors are installed on the steering conveyor at the roller intervals of the roller conveyor, and the conveying direction of the chain conveyors is consistent with the pallet output direction. A floating control device is provided between the steering conveyor and the output frame, and the floating control device is used to control the conveying surface of the chain conveyor to be lower or higher than the conveying surface of the roller conveyor.

This utility model is installed near the stacker crane. The pad receiving station receives stacks of pads. The distribution mechanism distributes one pad to the bottom plate distribution station and places it on the bottom plate input machine. The bottom plate input machine transports the pad to the side of the stacking platform. After a stack of plates is output from the stacking platform, the bottom plate input machine inputs a pad onto the stacking platform. Subsequent plates input onto the stacking platform are automatically stacked onto this pad, which naturally forms a support plate at the bottom of the stack. After stacking is complete, the stacking platform outputs the stack to the plate output machine on the other side. The plate output machine transports the stack with the bottom pad to the top plate distribution station. The distribution mechanism distributes one of the pads from the pad receiving station to the top plate distribution station and places it on top of the stack. At this point, both the top and bottom of the stack are equipped with upper and lower pads. These two pads, especially the bottom pad, provide comprehensive support for the stack, reducing deformation during subsequent transfer and storage, and preventing scratches and bumps on the bottom plate.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figure 1 and Figure 2 As shown, the pallet stack top and bottom protection system is used in conjunction with the stacker crane 1. The stacker crane 1 is equipped with a stacking platform 11 for supporting the pallet stack. Conventionally, the stacking platform 11 is a stacking platform 11 that can output the pallet stack to the side. More specifically, the platform surface of the stacking platform 11 is formed by the conveying surface of a set of roller conveying mechanisms. The above is known technology and will not be described in detail here.

[0022] This system includes a distribution frame 2, which is provided with a bottom plate distribution station 22, a top plate distribution station 23 and a pad receiving station 21. The distribution frame 2 is provided with a distribution mechanism 3 for distributing the pads 9 at the pad receiving station 21 to the bottom plate distribution station 22 or the top plate distribution station 23.

[0023] like Figures 3 to 5 As shown, the dispensing mechanism 3 in this embodiment includes a dispensing movable frame 31 that is horizontally movably installed on the dispensing frame 2, and a dispensing position control device 32 is provided between the dispensing movable frame 31 and the dispensing frame 2; a vertically movably arranged pick-and-place frame 33 is installed on the dispensing movable frame 31, and a pick-and-place height control device 34 is provided between the pick-and-place frame 33 and the dispensing movable frame 31; a pick-and-place device 35 is installed on the pick-and-place frame 33.

[0024] The distributing movable frame 31 is initially located at the pad receiving station 21. In use, the pick-and-place height control device 34 drives the pick-and-place frame 33 to descend to a designated height, and the pick-and-place device 35 picks up the top pad 9 of the pad stack. The pick-and-place height control device 34 then drives the pick-and-place frame 33 to rise to a certain height, and the distributing position control device 32 drives the distributing movable frame 31 to the bottom plate distributing station 22. The pick-and-place height control device 34 then drives the pick-and-place frame 33 to descend to a designated height, and the pick-and-place device 35 releases the pad 9, which is then placed. Then, the distributing position control device 32 and the pick-and-place height control device 34 drive the pick-and-place device 35 back to its original position. The principle of the distributing mechanism 3 to the top plate distributing station 23 is the same and will not be described further here.

[0025] The distribution position control device 32 includes two position control sprockets 321 rotatably mounted on the distribution frame 2. A position control chain 322 is mounted on both sprockets 321, and at least one link of the position control chain 322 is connected to the distribution movable frame 31. One of the position control sprockets 321 is connected to a position control motor 323. After the position control motor 323 controls the rotation of the position control sprocket 321, the position control chain 322 can pull the distribution movable frame 31 to move laterally. The distribution movable frame 31 is movably mounted on the distribution frame 2 via a mechanism such as a wheel-rail mechanism or a guide rail sliding sleeve mechanism. The position control motor 323 drives the distribution movable frame 31 in both forward and reverse directions.

[0026] The pick-and-place height control device 34 includes at least three height control straps 341 connected to the pick-and-place frame 33. A height control roller 342 is rotatably mounted on the distribution frame 31 corresponding to each height control strap 341. The upper end of each height control strap 341 is wound around the corresponding height control roller 342, and each height control roller 342 is connected to a height control motor 343. When the height control motor 343 rotates forward, it drives the height control roller 342 to wind up the height control strap 341, thereby raising the pick-and-place frame 33. Conversely, when the height control motor 343 rotates in reverse, it drives the height control roller 342 to release the height control strap 341. At this time, the overall gravity of the pick-and-place frame 33 and its structure also helps to lower the pick-and-place frame 33.

[0027] In actual setup, to improve the synchronization of the lifting and lowering drive of the pick-and-place frame 33, a height control transmission rod 344 is preferably rotatably mounted on the distribution movable frame 31. Two height control rollers 342 are mounted on the height control transmission rod 344, and two height control straps 341 are wound around the height control rollers 342. The two height control straps 341 extend in two opposite directions and are connected to the pick-and-place frame 33 downwards through guide rollers 345. This forms a four-point connection, and the rotation of one height control transmission rod 344 driven by the height control motor 343 can synchronously realize the raising and lowering of the four height control straps 341.

[0028] The pickup / placer 35 includes a pickup / placement suction cup that picks up the pad 9 by negative pressure adsorption; of course, mechanical grippers or the like can also be used. The pickup / placer 35 is a well-known technology that is known to those skilled in the art, and will not be described in detail here and is not shown in the figures.

[0029] Preferably, the pallet receiving station 21 is equipped with a pallet input machine 7 for inputting pallet stacks, thereby improving the automation level of pallet stack input. In this embodiment, the pallet input machine 7 is shown to be a roller conveyor structure.

[0030] like Figure 1 and Figure 2 As shown, the base plate distribution station 22 is equipped with a base plate input machine 4 for inputting pads 9 into the stacking platform 11. The distribution mechanism 3 places the pads 9 onto the base plate input machine 4. In this embodiment, the base plate input machine 4 includes an input frame, on which a base plate conveying frame 41 for reciprocating movement between the base plate distribution station 22 and the side of the stacking platform 11 is installed. A traveling device 43 is installed on the base plate conveying frame 41; a roller input device 44 for inputting pads 9 into the stacking platform 11 is installed on the base plate conveying frame 41.

[0031] The bottom plate conveyor 41 is initially positioned at the bottom plate distribution station 22. After the distribution mechanism 3 distributes a pad 9, the traveling device 43 drives the bottom plate conveyor 41 to the side of the stacking platform 11. After the stacked plates on the stacking platform 11 are output from the other side, the roller input device 44 inputs the pad 9 onto the stacking platform 11, completing the input of the bottom pad 9. During this input process, the roller input device 44 and the roller conveyor mechanism of the stacking platform 11 can temporarily form a complete conveyor line, smoothly inputting the pad 9 onto the stacking platform 11. After input is completed, the traveling device 43 drives the bottom plate conveyor 41 back to the bottom plate distribution station 22, waiting to place the next pad 9.

[0032] This embodiment illustrates that the stacker 1 is a dual-station alternating stacker 1, with two stacking platforms 11 used alternately for stacking. More specifically, after stacking is completed on one stacking platform 11, the other stacking platform 11 is switched for stacking. Thus, the base plate input machine 4 can reach the sides of both stacking platforms 11 to alternately input the base plate 9.

[0033] The input frame may be equipped with a base plate conveying track 2, the base plate conveying frame 41 is guided to move back and forth by the base plate conveying track 42, and the walking device 43 includes walking wheels corresponding to the base plate conveying track 42, at least one of the walking wheels is connected to a walking drive motor.

[0034] like Figure 1 and Figure 2 As shown, a pallet output machine 5 is provided on the side of the stacking platform 11. The pallet output machine 5 passes through the top plate distribution station 23 to realize the conveying of pallets to the top plate distribution station 23. In this embodiment, the pallet output machine 5 includes an output frame 51. A roller conveyor 52 for conveying from the side of the stacking platform 11 to the top plate distribution station 23 is installed on the output frame 51. A vertically movable steering conveyor frame is installed on the output frame 51 on the side of the stacking platform 11. A plurality of chain conveyor devices 53 located at the roller intervals of the roller conveyor device 52 are installed on the steering conveyor frame. The conveying direction of the chain conveyor device 53 is consistent with the pallet output direction. A floating control device is provided between the steering conveyor frame and the output frame 51. The floating control device is used to control the conveying surface of the chain conveyor device 53 to be lower or higher than the conveying surface of the roller conveyor device 52.

[0035] Before the stacking platform 11 outputs the pallet stack, the buoyancy control device drives the steering conveyor frame to rise, and the chain conveyor 53 is used to receive the pallet stack output by the stacking platform 11. When there is a distance between the stacking platform 11 and the chain conveyor 53, a transition conveyor 6 can be added between them for conveying. Based on this, the pallet receiving station 21 on the distribution frame 2 should preferably be located in the extension direction of the pallet from the stacker 1. The bottom plate distribution station 22 and the top plate distribution station 23 are located on both sides of the pallet receiving station 21, and the top plate distribution station 23 corresponds to the output side of the stacking platform 11, while the bottom plate distribution station 22 corresponds to the input side of the pallet 9 of the stacking platform 11. This simplifies the conveying path arrangement of the bottom plate input machine 4 and the pallet output machine 5. Of course, if two stacking platforms 11 are provided on the stacker 1, the roller conveyor 52 extends to the two stacking platforms 11, and the chain conveyor 53 is respectively arranged at the two stacking platforms 11.

[0036] The final output stacks are all located on the chain conveyor 53. The floating control device drives the steering conveyor frame to descend, and the conveying surface of the chain conveyor 53 is lower than the conveying surface of the roller conveyor 52. The stacks naturally fall onto the roller conveyor 52 and are then conveyed to the top plate distribution station 23.

[0037] The structures of the roller conveyor 52 and the chain conveyor 53 are known technologies in the art, and the floating and sinking control device can be implemented by a hydraulic cylinder with an upwardly extending piston rod.

[0038] Upon reaching the top plate distribution station 23, the distribution mechanism 3 places the picked-up pad 9 on top of the pallet stack. At this point, both the top and bottom of the pallet stack are covered with thick pads 9, providing support. From the initial stacking to subsequent transfer to warehouse storage, the bottom pad 9 provides stronger overall support. When stacking pallets of greater height in the warehouse, the top pad 9 also provides comprehensive support. Therefore, this embodiment, when used in conjunction with the existing stacker crane 1, helps reduce deformation of the pallet stack during subsequent transfer and storage, and also helps avoid scratches and bumps on the bottom pallet.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
