Description

Technical Field

[0001] This invention relates to the field of stacker cranes, and more specifically to a gypsum board stacking platform with a conveying function. Background Technology

[0002] Stacking platforms are typically scissor lifts installed inside the foundation pit. They use hydraulic power to lift their top plate, which is flush with the ground when it is lowered to its lowest height.

[0003] Therefore, forklift pallets are usually placed on the stacking platform. The boards are transported to the vicinity of the stacking platform by a belt conveyor and stacked on the forklift pallets. The height of the belt conveyor remains unchanged. For each board stacked, the elevator lowers by one layer of board thickness. After stacking is completed, the stacking platform is lowered to the same height as the ground. Workers use forklifts or pallet jacks to remove the forklift pallets and the boards above them.

[0004] Both forklifts and pallet jacks require manual operation, which means that moving the plates off the stacking platform requires a lot of manpower, resulting in high human resource costs. Summary of the Invention

[0005] The purpose of this invention is to provide a gypsum board stacking platform with a transmission function to solve the technical problem that existing stacking platforms require manual unloading and have high production costs.

[0009] Furthermore, the sheet material is conveyed along a first direction to the top of the actuator of the first conveyor. The first conveyor has multiple components and is distributed at equal intervals along a second direction, which is horizontal and perpendicular to the first direction. A lifting plate is provided between adjacent first conveyors. The lifting plate is driven by a first driver to move vertically up and down. The lifting plate can move above or below the actuator of the first conveyor.

[0010] Furthermore, the sheet material is conveyed along a first direction to the top of the actuator of the first conveyor; a first alignment device and a first stop are sequentially arranged on both sides of the first conveyor along the first direction, the first alignment device being used to push one side of the sheet material along the first direction so that the other side abuts against the first stop; a second alignment device and a second stop are sequentially arranged on both sides of the first conveyor along a second direction, the second direction being horizontal and perpendicular to the first direction, the second alignment device being used to push one side of the sheet material along the second direction so that the other side abuts against the second stop.

[0011] Furthermore, the first aligning device includes: a second driver disposed along a first direction on the feeding side of the first conveyor, the second driver having an actuator capable of moving linearly along the first direction and rotating around the first direction; and a first aligning plate fixedly mounted on the actuator of the second driver, the first aligning plate having a length perpendicular to the first direction.

[0012] Further, the first stop includes: a third driver, disposed along a first direction on the discharge side of the first conveyor, the third driver having an actuator capable of moving linearly along the first direction, the output force of the third driver being greater than the output force of the second driver; and a first baffle, fixedly installed on the actuator of the third driver, the first baffle having a vertical length.

[0013] Furthermore, the third drive is connected to the frame via a fourth drive, the fourth drive having an actuator capable of moving vertically, the fourth drive being used to drive the third drive to move vertically.

[0016] Furthermore, the fifth driver is connected to the frame via a sixth driver, the sixth driver having an actuator capable of moving linearly along a second direction, the sixth driver being used to drive the fifth driver to move stepwise along the second direction.

[0017] Compared with the prior art, this application has the following advantages:

[0018] A sheet metal stacking platform with a transmission function is provided, which includes a lift and a first conveyor.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This specific implementation provides Example 1, please refer to it. Figures 1 to 8 .

[0032] A sheet metal stacking platform with a conveying function includes:

[0033] Elevator 2 has an actuator capable of vertical lifting;

[0034] The first conveyor 3 has an actuator for stacking plates and for horizontally conveying plates, and the first conveyor 3 is fixedly connected to the actuator of the elevator 2.

[0035] The elevator 2 is a scissor lift. The actuator of the elevator 2 is its own top plate. In order to make the elevator 2 work more stably, the top plate of the elevator 2 is connected to four columns through four rollers (not shown in the figure).

[0036] The first conveyor 3 is a chain plate conveyor, and the actuator of the first conveyor 3 refers to its own chain plate.

[0037] The elevator 2 is located beside the gypsum board conveyor line 1. The gypsum board conveyor line 1 transports gypsum boards horizontally to the execution part of the first conveyor 3, and stacks the gypsum boards above the execution part of the first conveyor 3. For each layer of gypsum boards stacked, the elevator 2 drives the first conveyor 3 to descend one layer, so that the height difference between the gypsum board conveyor line 1 and the execution part of the first conveyor 3 remains constant.

[0038] Once the gypsum board stacking is complete, the elevator 2 drives the first conveyor 3 to descend to its lowest height. At this time, the railcar 11, equipped with the second conveyor 12, moves to the side of the elevator 2. The first conveyor 3 and the second conveyor 12 are aligned. The second conveyor 12 is a chain plate conveyor that moves in the same direction as the first conveyor 3. The first conveyor 3 and the second conveyor 12 work at the same speed and in the same direction so that the gypsum board can be smoothly transferred from the first conveyor 3 to the second conveyor 12. Then the railcar 11 moves and carries the gypsum board on the second conveyor 12 to the next work station.

[0039] Furthermore:

[0040] Because the first conveyor 3 needs to be able to transport gypsum boards smoothly, the friction between the chain plate of the first conveyor 3 and the gypsum board is relatively large. This causes the first gypsum board (the bottom layer of the stacked gypsum boards) to stop moving after one end of the gypsum board comes into contact with the chain plate when it is transported to the chain plate of the first conveyor 3 via the gypsum board conveyor line 1, while the other end of the gypsum board slips on the transmission surface of the gypsum board conveyor line 1.

[0041] To solve the above technical problems, the following three technical methods can be used:

[0042] Firstly, before the first gypsum board is conveyed from the gypsum board conveyor line 1 to the first conveyor 3, a gypsum board can be manually moved and stacked on the first conveyor 3. In this way, one end of the gypsum board subsequently conveyed by the gypsum board conveyor line 1 contacts the top surface of the next layer of gypsum board, rather than directly contacting the chain plate. The friction between the gypsum boards is small, and there will be no problem of hindering the movement of the gypsum board conveyor line 1.

[0043] Secondly, based on Embodiment 1, this specific implementation also provides Embodiment 2, please refer to... Figure 1 .

[0044] The sheet material is conveyed along the first direction to the top of the actuator of the first conveyor 3, and the conveying direction of the first conveyor 3 is the same as the first direction.

[0045] The gypsum board is transported via gypsum board conveyor line 1. The first direction is the transport direction of gypsum board conveyor line 1. Before the first gypsum board is transported from gypsum board conveyor line 1 to the first conveyor 3, the first conveyor 3 starts to operate and maintains the same transport direction and speed as gypsum board conveyor line 1. One end of the first gypsum board falls from gypsum board conveyor line 1 and abuts against the chain plate of the first conveyor 3. The gypsum board and the chain plate of the first conveyor 3 remain relatively stationary due to friction. Since the first conveyor 3 and gypsum board conveyor line 1 maintain the same speed and direction of transport, both ends of the gypsum board move at the same speed under the action of the first conveyor 3 and gypsum board conveyor line 1 until the gypsum board is completely moved from gypsum board conveyor line 1 to the first conveyor 3. Then the first conveyor 3 stops, and the elevator 2 drives the first conveyor 3 to descend one level. Gypsum board conveyor line 1 continues to transport gypsum board above the first conveyor 3.

[0046] Thirdly, based on Example 1, this specific embodiment also provides Example 3, please refer to... Figure 7 and Figure 8 .

[0047] The sheet material is conveyed along the first direction to the top of the execution part of the first conveyor 3. There are multiple first conveyors 3 and they are distributed at equal intervals along the second direction. The second direction is horizontal and perpendicular to the first direction. A lifting plate 31 is provided between adjacent first conveyors 3. The lifting plate 31 is driven by the first driver 32 to move vertically up and down. The lifting plate 31 can move above or below the execution part of the first conveyor 3.

[0048] The gypsum board is transported via the gypsum board conveyor line 1. The first direction is the transport direction of the gypsum board conveyor line 1. The lifting plate 31 is made of nylon board, and the first driver 32 is a cylinder. Before the gypsum board conveyor line 1 transports the first gypsum board to the first conveyor 3, the first driver 32 drives the lifting plate 31 to rise. One end of the first gypsum board contacts the lifting plate 31 and slides along the lifting plate 31 until the gypsum board falls completely onto the lifting plate 31. Then the first driver 32 drives the lifting plate 31 to descend, and the gypsum board is transferred from the lifting plate 31 to the execution part of the first conveyor 3. The elevator 2 drives the first conveyor 3 to descend one layer, and the gypsum board conveyor line 1 continues to transport gypsum board above the first conveyor 3.

[0049] Furthermore:

[0050] Since the gypsum board continues to move due to inertia after separating from the gypsum board conveyor line 1, the endpoint of the gypsum board is uncertain. This results in uneven edges of the gypsum board stacked on the first conveyor 3, affecting subsequent conveying and packaging.

[0051] To solve the above-mentioned technical problems, based on any one of Embodiments 1, 2, and 3, this specific embodiment also provides Embodiment 4, which please refer to. Figure 3-7 .

[0052] The sheet material is conveyed along the first direction to the top of the actuator of the first conveyor 3;

[0053] A first alignment device 4 and a first stop 5 are arranged sequentially along the first direction on both sides of the first conveyor 3. The first alignment device 4 is used to push one side of the plate along the first direction so that the other side abuts against the first stop 5.

[0054] A second alignment device 6 and a second stop 7 are respectively located on both sides of the first conveyor 3 along the second direction. The second direction is horizontal and perpendicular to the first direction. The second alignment device 6 is used to push one side of the plate along the second direction so that the other side abuts against the second stop 7.

[0055] After each plasterboard is conveyed to the top of the first conveyor 3, the first alignment device 4 and the second alignment device 6 work to align the two right-angled edges of the plasterboard with the first stop 5 and the second stop 7 respectively, thereby making the edges of each plasterboard flat.

[0056] Furthermore:

[0057] Let the height of the highest piece of gypsum board stacked on the first conveyor 3 be H1, and the height of the output end of the gypsum board conveyor line 1 be H2, then H2 > H1.

[0058] During the process of the sheet material being transported along the first direction to the execution part of the first conveyor 3, the execution part of the first alignment device 4 should be located at a position higher than H2 or lower than H1 to avoid the sheet material hitting the execution part of the first alignment device 4 and stopping its movement.

[0059] After the plates are stacked onto the first conveyor 3, the actuator of the first alignment device 4 needs to move to a position below H2 and above H1 so that the actuator of the first alignment device 4 can push the side wall of the plates to align the plates with the first stop 5.

[0060] To achieve the above objectives, based on Example 4, this specific embodiment also provides Example 5, please refer to... Figure 6 .

[0061] The first alignment device 4 includes:

[0062] The second driver 41 is disposed on the feeding side of the first conveyor 3 along the first direction. The second driver 41 has an actuator that can move linearly along the first direction and rotate around the first direction.

[0063] The first striking plate 42 is fixedly installed on the actuator of the second driver 41, and the first striking plate 42 has a length perpendicular to the first direction.

[0064] The second driver 41 can be a rotary pressing cylinder, which can push the first clapper 42 to move linearly along the first direction, and can make the first clapper 42 rotate 90 degrees while moving linearly, so that the first clapper 42 can rotate from a horizontal posture to a vertical posture and push the plasterboard to align with the first stop 5.

[0065] The second driver 41 can also be a combination of a linear cylinder and a swing cylinder, which can also drive the first platen 42 to rotate to a horizontal position to avoid the plasterboard being transported from the plasterboard conveyor line 1 to the first conveyor 3, or drive the first platen 42 to rotate to a vertical position to push the plasterboard to align with the first stop 5.

[0066] For example, a linear cylinder, a swing cylinder, and a first striking plate 42 are connected in sequence, or a swing cylinder, a linear cylinder, and a first striking plate 42 are connected in sequence, wherein the output direction of the linear cylinder is parallel to the swing axis of the swing cylinder and both are oriented towards the first direction.

[0067] The first clapper 42 is made of nylon; or the first clapper 42 is made of metal, with a nylon plate installed on the side that contacts the plasterboard.

[0068] Furthermore:

[0069] Normally, the first stop 5 is a fixed stop, that is, a metal baffle that is fixed in place. Its surface is covered with leather or rubber to reduce the damage to its own side wall caused by the plasterboard hitting the first stop 5.

[0070] However, leather or rubber has a high frictional force. When the elevator 2 drives the first conveyor 3 to descend one floor, the side wall of the gypsum board will rub against the first stop 5. Over time, this can easily damage the skin of the metal baffle.

[0071] To address the aforementioned issues, based on Example 5, this specific embodiment also provides Example 6, which you can refer to. Figure 6 .

[0072] The first stop 5 includes:

[0073] The third driver 51 is disposed on the discharge side of the first conveyor 3 along the first direction. The third driver 51 has an actuator that can move linearly along the first direction. The output force of the third driver 51 is greater than the output force of the second driver 41.

[0074] The first baffle 52 is fixedly installed on the actuator of the third driver 51, and the first baffle 52 has a vertical length.

[0075] The third actuator 51 is a cylinder, and the first baffle 52 is a metal baffle. The side of the baffle facing the plasterboard can be fitted with a nylon board or a skin. The output force of the third actuator 51 is greater than the output force of the second actuator 41, so that when the plasterboard pushed by the second actuator 41 hits the first baffle 52, the first baffle 52 is equivalent to a stationary dead stop.

[0076] Before the elevator 2 drives the first conveyor 3 to descend one floor, the third driver 51 drives the first baffle 52 away from the plasterboard. Then the first conveyor 3 descends, and then the third driver 51 drives the first baffle 52 to reset. This avoids friction between the side wall of the plasterboard and the first baffle 52.

[0077] Furthermore:

[0078] After the gypsum boards are stacked, they need to be moved above the elevator 2 by the first conveyor 3. At this time, the first baffle 52 will hinder the discharge of the top few gypsum boards.

[0079] The above problem can be solved by further reducing the height by 300, or by other technical means. For example, this specific embodiment also provides two embodiments, please refer to them. Figure 6 .

[0080] Example 7, based on Example 6:

[0081] The third drive 51 is connected to the frame via the fourth drive 53, which has an actuator capable of moving in a vertical direction and is used to drive the third drive 51 to move vertically.

[0082] Example 8, based on Example 4:

[0083] The first stop 5 includes:

[0084] The fourth drive 53 is provided on the discharge side of the first conveyor 3 and has an actuator capable of moving linearly in the vertical direction;

[0085] The first baffle 52 is fixedly installed on the actuator of the fourth driver 53, and the first baffle 52 has a vertical length.

[0086] The fourth drive 53 is a roller chain slide or a ball screw slide. The fourth drive 53 is used to drive the third drive 51 or the first baffle 52 to rise so that the first baffle 52 can avoid the trajectory of the first conveyor 3 driving the gypsum board to be discharged.

[0087] Optionally, based on Example 4, this specific embodiment also provides Example 9.

[0088] The second alignment device 6 includes:

[0089] The fifth drive 61 is disposed on the side of the first conveyor 3 along the second direction, and the fifth drive 61 has an actuator capable of moving linearly along the second direction;

[0090] The second beater 62 is fixedly installed on the actuator of the fifth driver 61, and the second beater 62 has a vertical length.

[0091] The fifth actuator 61 uses a cylinder, and the second beater 62 has the same structure and material as the first beater 42.

[0092] Furthermore:

[0093] Because the production lengths of different batches of gypsum board vary, the distance between the second alignment device 6 and the second stop 7 also needs to be adjusted. Based on the above reasons, this specific embodiment also provides Embodiment 10, which can be found in Example 4. Figure 7 or Figure 8 .

[0094] The fifth drive 61 is connected to the frame via the sixth drive 63, which has an actuator capable of moving linearly along the second direction. The sixth drive 63 is used to drive the fifth drive 61 to move stepwise along the second direction.

[0095] The sixth actuator 63 uses a servo electric actuator to adjust the distance between the second beater 62 and the second stop 7 so that it is equal to the length of the plasterboard.

[0096] Optionally, based on Example 4, this specific embodiment also provides Example 11.

[0097] The second stop 7 includes a seventh driver 71 and a second baffle 72. The seventh driver 71 has the same structure as the third driver 51, and the second baffle 72 has the same structure as the first baffle 52.

[0098] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of the embodiments of the present invention.
