An automatic stacking system for gypsum boards

Abstract

The present invention discloses an automatic stacking system for gypsum boards, which includes a stacking platform and a handling robot. The handling robot is used to move scattered boards to the stacking platform. Among them, the stacking platform includes a first elevator and a first conveyor. The first elevator has an execution part that can vertically lift, and the first conveyor has an execution part for stacking boards and capable of horizontally conveying boards. The first conveyor is fixedly connected to the execution part of the first elevator. By stacking the boards through the execution part of the first conveyor, after the board stacking is completed, the stacked boards can be directly moved to a transfer trolley or other conveyor lines through the first conveyor, without manual handling. At the same time, the handling robot transports the first board to the execution part of the first conveyor to prevent the board from getting stuck due to friction with the execution part of the first conveyor or the bottom surface of the board from being scratched when the board moves from the upstream station to the first conveyor.

Description

Technical Field

[0001] The present invention relates to the field of stackers, and particularly to an automatic stacking system for gypsum boards. Background Art

[0002] After being produced, gypsum boards are scattered on a conveyor line. The conveyor line transports the gypsum boards to a location where they are stacked in several layers and then packaged and loaded onto a vehicle.

[0003] Currently, people usually use a lift as a stacking platform for gypsum boards. A forklift pallet is usually placed on the lift. The boards are transported to the vicinity of the lift by a belt conveyor and stacked on the forklift pallet. The height of the belt conveyor remains unchanged. For each board stacked, the lift descends by the thickness of one board. After stacking is completed, the lift descends to a height flush with the ground, and workers use a forklift or a pallet jack to remove the forklift pallet and the boards above it.

[0004] Since both the forklift and the pallet jack require manual operation, a large amount of manpower is needed to remove the boards on the stacking platform, resulting in too high a cost of human resources. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic stacking system for gypsum boards to solve the technical problem that the existing stacking platform requires manual unloading and has a high production cost.

[0006] To solve the above technical problem, the present invention specifically provides the following technical solutions:

[0008] Further, there are a plurality of the first conveyors and they are equally spaced along a first direction, and the gap between two adjacent first conveyors is greater than the width of a forklift rod.

[0009] Further, the boards are transported from the upstream station along the first direction above the first conveyor.

[0010] Further, a first aligning device and a first stopper are sequentially arranged along a first direction on both sides of the first conveyor. The first direction is horizontal and perpendicular to one side of the plate. The first aligning device is configured to push one side of the plate to move along the first direction so that the other side thereof abuts against the first stopper. A second aligning device and a second stopper are sequentially arranged along a second direction on both sides of the first conveyor. The second direction is horizontal and perpendicular to the first direction. The second aligning device is configured to push one side of the plate to move along the second direction so that the other side thereof abuts against the second stopper.

[0011] Further, a second conveyor is arranged at the discharge side of the first conveyor. When the execution part of the first elevator is at the lowest height, the first conveyor is flush with the second conveyor, and the conveying directions of the first conveyor and the second conveyor are the same.

[0012] Further, the second conveyor is installed on a first rail vehicle, and the second conveyor moves through the first rail vehicle.

[0013] Further, the first elevator is installed on a first rail vehicle, and the first elevator and the first conveyor move through the first rail vehicle.

[0014] Further, there are two stacking platforms which alternately perform stacking and discharging operations, and the handling robot is arranged between the two stacking platforms.

[0015] Further, a second elevator is arranged beside the first elevator. The second elevator is used for placing the stacked plates, and the handling robot is used for moving the plates stacked on the second elevator to the first conveyor.

[0016] Further, the handling robot includes: a track which is horizontally arranged at a position higher than the stacking platform and passes directly above the stacking platform; a second rail vehicle which is connected to the track and travels through the track; a telescopic arm which has an execution part capable of vertically lifting and lowering, and the telescopic arm is fixedly connected to the execution part of the second rail vehicle; and an adsorption assembly which has an execution part capable of adsorbing the plates, and the adsorption assembly is fixedly connected to the execution part of the telescopic arm.

[0017] The present application has the following beneficial effects compared with the prior art:

[0018] An automatic stacking system for gypsum boards is provided, in which the boards are stacked by the executive part of a first conveyor, so that after the stacking of the boards is completed, the stacked boards can be directly moved to a material transfer trolley or other conveyor line by the first conveyor without manual handling; at the same time, a handling robot transports the first board to the executive part of the first conveyor to prevent the board from being stuck due to friction with the executive part of the first conveyor when moving the board from an upstream workstation to the first conveyor, or the bottom surface of the board from being scratched.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 8 , this specific implementation manner provides Embodiment 1.

[0033] An automatic stacking system for gypsum boards includes:

[0034] A stacking table 2 for obtaining scattered boards from an upstream station and stacking the boards layer by layer and then transmitting them to a downstream station;

[0035] A handling robot 3 for moving the scattered boards to the stacking table 2;

[0036] Among them, the stacking table 2 includes:

[0037] A first elevator 21 having an executing part that can vertically lift;

[0038] A first conveyor 22 having an executing part for stacking boards and capable of horizontally conveying the boards, and the first conveyor 22 is fixedly connected to the executing part of the first elevator 21.

[0039] The upstream transmission line transports the gypsum boards above the first conveyor 22. For each layer of gypsum board stacked, the first elevator 21 drives the first conveyor 22 to descend one layer. After the gypsum boards are stacked, the first conveyor 22 drives the stacked gypsum boards to move to the downstream transmission line, and the stacked gypsum boards move to the packing station through the downstream transmission line.

[0040] The above-mentioned upstream and downstream transmission lines can be belt conveyors, chain plate conveyors, etc.

[0041] The first elevator 21 adopts a scissor lift. The executing part of the first elevator 21 refers to its own top plate. In order to make the first elevator 21 work more smoothly, the top plate of the first elevator 21 is connected to the four columns through four rollers (not shown in the figure).

[0042] The first conveyor 22 is a chain plate conveyor, and the execution part of the first conveyor 22 refers to its own chain plates.

[0043] Since the first conveyor 22 needs to be able to smoothly transport the gypsum boards, the friction between the chain plates of the first conveyor 22 and the gypsum boards is relatively large. As a result, when the first gypsum board (the lowermost layer of the stacked gypsum boards) is transported from the upstream transmission line to the chain plates of the first conveyor 22, one end of the gypsum board stops moving after contacting the chain plates, while the other end of the gypsum board slips on the transmission surface of the belt conveyor 1.

[0044] To avoid the above technical problems, before the belt conveyor 1 transports the first gypsum board to the first conveyor 22, the handling robot 3 transports the gypsum board to the first conveyor 22. After there is at least one gypsum board on the first conveyor 22, the belt conveyor 1 starts to transport the gypsum board to the first conveyor 22. The friction between the gypsum boards is relatively small, and the problem of jamming will not occur.

[0045] In this embodiment:

[0046] The upstream transmission line is the belt conveyor 1. The first elevator 21 is arranged beside the belt conveyor 1. The belt conveyor 1 transports the gypsum boards along the horizontal direction to the execution part of the first conveyor 22 and stacks the gypsum boards above the execution part of the first conveyor 22. The height difference between the belt conveyor 1 and the execution part of the first conveyor 22 is constant.

[0047] Furthermore:

[0048] To avoid the situation where the entire production line is forced to stop when the first conveyor 22 fails and cannot transport the gypsum boards outwards, on the basis of Embodiment 1, this specific embodiment also provides Embodiment 2. [[ID=2l]]

[0049] The first conveyor 22 has a plurality of them and is distributed at equal intervals along the first direction. The gap between two adjacent first conveyors 22 is greater than the width of the forklift rod.

[0050] When the first conveyor 22 fails and cannot work, the staff can insert the forklift rod into the gap between the first conveyors 22 and use the forklift to move the gypsum boards above the first conveyor 22 to avoid the production line from stopping.

[0051] Furthermore:

[0052] To provide a larger working area for the forklift and facilitate the staff to use the forklift to move the gypsum boards from the first conveyor 22, on the basis of Embodiment 2, this specific embodiment also provides Embodiment 3.

[0053] The sheet material is transferred from the upstream workstation along the first direction to above the first conveyor 22 .

[0054] When the staff uses a forklift to transport the gypsum boards, the forklift and the belt conveyor 1 are respectively located on both sides of the stacking platform 2, so the forklift has a wide working area, which is convenient for the staff to operate.

[0055] Further:

[0056] Since the gypsum board continues to move under the action of inertia after being separated from the belt conveyor 1, the end point of the gypsum board is uncertain, which causes the edges of the gypsum boards stacked on the first conveyor 22 to be uneven, affecting subsequent transportation and packaging.

[0057] In order to solve the above technical problems, based on any one of Examples 1-3, this specific implementation manner further provides Example 4.

[0058] A first aligning device 23 and a first stopper 24 are sequentially arranged on both sides of the first conveyor 22 along a first direction. The first direction is horizontal and perpendicular to one side of the plate. The first aligning device 23 is used to push one side of the plate to move along the first direction so that the other side abuts against the first stopper 24.

[0059] A second aligning device 25 and a second stop 26 are sequentially arranged on both sides of the first conveyor 22 along the second direction. The second direction is horizontal and perpendicular to the first direction. The second aligning device 25 is used to push one side of the plate to move along the second direction so that the other side abuts against the second stop 26.

[0060] After each gypsum board is transferred to the top of the first conveyor 22, the first aligning device 23 and the second aligning device 25 work to align the two right-angled sides of the gypsum board with the first stop 24 and the second stop 26 respectively, so that the edge of each gypsum board is flat.

[0061] In the above technical means, the first stop 24 and the second stop 26 are both dead stops, that is, stop plates made of metal or plastic and fixed in position, and the first aligning device 23 and the second aligning device 25 are both movable push rods with power sources. The first aligning device 23 and the second aligning device 25 perform corresponding actions through their own power sources, including linear propulsion, stepping or rotational actions, to align the gypsum board.

[0062] Further:

[0063] The first conveyor 22 as a chain-type conveyor can move the gypsum boards stacked above it, but it also needs equipment that can take over the transferred stacked gypsum boards to prevent the gypsum boards from falling over or tilting during the transfer process.

[0064] To achieve the above object, based on any one of Embodiments 1-4, this specific embodiment further provides three feasible implementation manners.

[0065] Firstly, Embodiment 5.

[0066] A second conveyor 4 is provided on the discharge side of the first conveyor 22. When the actuator of the first elevator 21 is at the lowest height, the first conveyor 22 is flush with the second conveyor 4, and the conveying directions of the first conveyor 22 and the second conveyor 4 are the same.

[0067] The second conveyor 4 adopts a chain plate conveyor in the same direction as the first conveyor 22. The first conveyor 22 and the second conveyor 4 work at the same speed and in the same direction, so that the gypsum board can be smoothly transferred from the first conveyor 22 to the second conveyor 4, and then the second conveyor 4 directly transfers the stacked gypsum board to the downstream station.

[0068] Secondly, Embodiment 6.

[0069] A second conveyor 4 is provided on the discharge side of the first conveyor 22. The second conveyor 4 is installed on the first rail car 5 and moves through the first rail car 5. When the actuator of the first elevator 21 is at the lowest height, the first conveyor 22 is flush with the second conveyor 4, and the conveying directions of the first conveyor 22 and the second conveyor 4 are the same.

[0070] The first conveyor 22 and the second conveyor 4 work together to transfer the stacked gypsum board onto the first rail car 5, and the gypsum board is transferred to the downstream station through the first rail car 5 and the second conveyor 4. The relevant equipment at the downstream station cooperates with the second conveyor 4 to remove the gypsum board.

[0071] Thirdly, Embodiment 7.

[0072] The first elevator 21 is installed on the first rail car 5, and the first elevator 21 and the first conveyor 22 move through the first rail car 5.

[0073] The drawing of Embodiment 7 is not shown. In Embodiment 7, the stacking table 2 is integrated with the first rail car 5. After the first rail car 5 moves the stacking table 2 to the downstream station, the relevant equipment at the downstream station cooperates with the first conveyor 22 to remove the gypsum board, and then the first rail car 5 drives the stacking table 2 back to the original position.

[0074] Furthermore:

[0075] When the first conveyor 22 discharges materials, the subsequent gypsum boards cannot be conveyed to it, that is, the belt conveyor 1 needs to stop, which causes the entire production line to stop production. To avoid this situation, based on any one of the above embodiments, this specific embodiment further provides Embodiment 8.

[0076] The stacking table 2 has two and alternately performs stacking and discharging operations. The handling robot 3 is arranged between the two stacking tables 2.

[0077] When one stacking table 2 finishes stacking and discharging, the other stacking table 2 is used for stacking gypsum boards so that the production of gypsum boards can proceed without interruption.

[0078] Furthermore:

[0079] The number of gypsum boards transferred by the handling robot 3 to the stacking table 2 means that the same number of gypsum boards need to be pre-stacked in the working area of the handling robot 3. If the gypsum boards are stacked less, it will cause the staff to continuously replenish the gypsum boards, which is time-consuming and laborious. If the gypsum boards are stacked more, it will cause the execution part of the handling robot 3 to be able to move vertically a larger distance, significantly increasing the production cost of the handling robot 3.

[0080] To solve the above technical problems, on the basis of any one of the above embodiments, this specific embodiment further provides Embodiment 9.

[0081] A second elevator 6 is arranged beside the first elevator 21. The second elevator 6 is used for placing the stacked plates, and the handling robot 3 is used for moving the stacked plates on the second elevator 6 to the first conveyor 22.

[0082] After the handling robot 3 takes away one gypsum board from the second elevator 6 and places it on the first conveyor 22 each time, the second elevator 6 rises by the thickness of one gypsum board so that the execution part of the handling robot 3 only needs to descend the same height each time to obtain the gypsum board.

[0083] Optionally, on the basis of any one of the above embodiments, this specific embodiment further provides Embodiment 10.

[0084] The handling robot 3 includes:

[0085] A track 31, horizontally arranged at a position higher than the stacking table 2 and passing directly above the stacking table 2;

[0086] A second rail car 32, connected to the track 31 and traveling through the track 31;

[0087] A telescopic arm 33, having an execution part that can be vertically lifted and lowered. The telescopic arm 33 is fixedly connected to the second rail car 32;

[0088] An adsorption assembly 34, having an execution part that can adsorb the plates. The adsorption assembly 34 is fixedly connected to the execution part of the telescopic arm 33.

[0089] In the combination of Embodiments 8, 9, and 10, the track 31 connects two first conveyors 22 and passes directly above the second elevator 6. The telescopic arm 33 is a servo electric push rod. The adsorption assembly 34 includes a plurality of vacuum suction cups and a vacuum pump that enables the vacuum suction cups to have adsorption force.

[0090] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present invention.
