Description

Technical Field

[0001] This utility model relates to the field of industrial robot handling, specifically a refractory brick kiln stacking system. Background Technology

[0002] Before refractory bricks are fired in the kiln, they need to be neatly stacked on trays. In order to maximize the utilization of kiln space and ensure ventilation and stability, when stacking the brick blanks, it is necessary to ensure that the stack is stable to prevent collapse due to vibration or high temperature during firing. At the same time, attention should be paid to ventilation, and a certain gap should be left between the bricks so that the refractory bricks are heated evenly during firing to avoid product quality problems caused by local overheating or underfiring.

[0003] Because gaps need to be maintained during stacking, current stacking operations are either based on manual placement or the use of robotic arms to place each brick individually. Robotic arms offer advantages in maintaining gaps and stability, but because they perform a grab-move-place action on each brick, their efficiency is actually less than ideal. Therefore, improving stacking efficiency while ensuring uniform gaps is a weak link in the pre-kiln operations. Utility Model Content

[0004] The purpose of this invention is to provide a refractory brick kiln stacking system that can grab multiple bricks at once and stack them in batches at equal intervals, thereby greatly improving the brick preparation efficiency of the kiln.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A stacking system for refractory brick kilns includes a gripper module. The gripper module includes a base frame, and a first gripper mechanism and a second gripper mechanism are installed side by side and parallel to each other below the base frame. The first gripper mechanism includes a first gripper plate that is equidistant from each other, and the second gripper mechanism includes a second gripper plate that is equidistant from each other. The first gripper mechanism and the second gripper mechanism have opposite linear travels, and the first gripper plate and the second gripper plate can be brought together or separated based on their opposite linear travels.

[0007] The base frame is a long strip frame structure. The first gripper mechanism includes a frame frame located below the base frame. The frame frame has crossbeams equidistantly arranged along its length. The first gripper plate is fixed to the bottom side of the crossbeams. The second gripper mechanism includes strip frames located on both sides of the first gripper mechanism. The strip frames have reinforcing ribs equidistantly arranged on them. The second gripper plate is fixed to the bottom side of the strip frames.

[0008] The frame is provided with upper and lower guide rails on both sides, which are arranged side by side. The top of the frame is provided with two upright plates, which are symmetrically arranged relative to the crossbeam. The top of the outer end face of the upright plate is provided with an upper sliding sleeve, through which the upper guide rail passes and the two are slidably connected. The top side of the strip frame is provided with two second sliding sleeves symmetrically arranged on the left and right sides, through which the lower guide rail passes and the two are horizontally slidingly engaged.

[0009] An inner protruding seat is fixed to the frame, and a first vertically extending support arm is fixed to the inner protruding seat. An outer protruding seat is provided on the strip frame, and a second vertically extending support arm is fixed to the outer protruding seat. A mounting seat is fixed to one side of the base frame, and a double-headed cylinder is fixed below the mounting seat. The two ends of the double-headed cylinder are respectively provided with a first cylinder rod and a second cylinder rod that are in reverse telescopic cooperation. The end of the first cylinder rod is fixed to the top of the first support arm, and the end of the second cylinder rod is fixed to the top of the second support arm.

[0010] When the first and second cylinder rods retract into the double-ended cylinder body, the first and second gripping plates are arranged on the same plane.

[0011] When the action of extending the first and second cylinder rods out of the double-ended cylinder body is initiated, the first and second gripping plates move away from each other.

[0012] It also includes a moving module, which includes a ground rail on which a gantry with a linear travel distance is mounted. A transverse trolley with a lateral linear travel distance is mounted on the top of the gantry. A lifting frame is mounted below the transverse trolley. The bottom of the lifting frame is used for fixed installation with the top of the base frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This system achieves batch, evenly spaced gripping capability through improvements to the gripper mechanism. By bringing the first and second grippers together or separating, they can cooperate with adjacent first or second grippers to clamp bricks. This enables batch, evenly spaced gripping and placement, resulting in uniform and consistent spacing between bricks after placement, eliminating size errors. This ensures spacing accuracy and significantly improves palletizing efficiency through batch operations. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Example:

[0024] In production, stacking speed is crucial. Firstly, from the kiln's perspective, excessively slow stacking leads to prolonged charging time, indirectly impacting the kiln's thermal efficiency by increasing heat loss, heat storage loss, flue gas heat loss, and incomplete fuel combustion. Secondly, slow stacking results in prolonged exposure of the bricks, potentially causing them to absorb excessive moisture and become contaminated with dust or other impurities, thus affecting firing quality. Furthermore, the bottom layer of bricks may shrink prematurely due to the long wait, while the upper layers shrink more slowly, leading to uneven shrinkage and potentially cracking. Therefore, stacking speed not only affects production efficiency but also has a critical impact on production costs and quality.

[0025] However, the advanced palletizing equipment now mainly relies on multi-axis robotic arms, which can only grab one brick per cycle. While the accuracy of palletizing is achieved, the efficiency may be lower than that of manual labor.

[0026] Therefore, the main improvement of this palletizing system is to the mechanical gripper, enabling it to grab multiple pieces at once and stack them at equal intervals.

[0027] The main structure includes: a moving module and a gripper module.

[0028] Since the improvements are mainly based on the gripper module, this part will be described first.

[0029] The gripper module includes:

[0030] Base frame 1, first gripper mechanism, second gripper mechanism.

[0031] The top of the base frame 1 is used to connect and cooperate with the moving module, which controls the position of the gripper module and realizes the movement function. The top of the base frame 1 is provided with a base for fixing the moving module.

[0032] The base frame 1 adopts a long strip-shaped metal frame structure. Corner frames 2 are respectively provided at both ends of the long side of the base frame 1, and the corner frames 2 are distributed at the four corner points of the base frame 1. An upper guide rail 3 and a lower guide rail 4 are fixed to each other between the corner frames 2 on the same side. The upper guide rail 3 and the lower guide rail 4 are both optical axis circular rods, which provide stable support and guidance.

[0033] The first gripper mechanism includes a frame located below the base frame 1. The frame is a rectangular metal frame arranged in the same direction as the base frame 1. Crossbeams 5 are equidistantly spaced along the length of the frame. A first gripping plate 6 is located below each crossbeam 5, and the first gripping plate 6 is erected. The surface of the first gripping plate 6 can be covered with a rubber layer. The structure of the crossbeams 5 makes the fixation of the first gripping plate 6 more stable and reliable, and also facilitates obtaining a thin gripping plate structure. Alternatively, the top side of the gripping plate can be directly fixed to the frame.

[0034] The top of the frame has two upright plates 7, which are fixed to both sides of the long side of the frame and are symmetrically arranged relative to the crossbeam 5. The upright plates 7 are centered relative to the frame. The top of the outer end face of the upright plate 7 is provided with an upper sliding sleeve 8, and the upper guide rail 3 passes through the upper sliding sleeve 8 and the two are slidably connected. This guides the sliding stroke of the first gripper mechanism relative to the base frame 1 in the length direction.

[0035] The frame is also fixed with an inner protrusion 9, and a first support arm 10 extending vertically upward is fixed on the inner protrusion 9.

[0036] The second gripper mechanism includes strip frames 11 located on both sides of the first gripper mechanism. In this example, the strip frames 11 are symmetrically arranged relative to the frame frame, but this is not limited to this example. They can also be arranged only on one side of the frame frame.

[0037] The strip frame 11 is provided with reinforcing ribs 12 at equal intervals. The reinforcing ribs 12 can improve the support strength of the strip frame 11. A second gripping plate 13 is fixed below the reinforcing ribs 12. The second gripping plate 13 and the first gripping plate 6 are arranged in the same direction and have corresponding thicknesses. The bottom side of the second gripping plate 13 corresponds to the bottom side of the first gripping plate 6.

[0038] The top side of the strip frame 11 is symmetrically provided with two second sliding sleeves 14. The second sliding sleeves 14 are penetrated by the lower guide rail 4 and the two slide horizontally. The strip frame 11 is also provided with a protruding outer convex seat 17, and a second support arm extending vertically upward is fixed on the outer convex seat 17.

[0039] A mounting base 15 is fixed to one side of the base frame 1. The mounting base 15 is made of angle iron, which is simple and sturdy. A double-headed cylinder body 16 is fixed below the mounting base 15. The double-headed cylinder body 16 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The two ends of the double-headed cylinder body 16 are respectively provided with a first cylinder rod and a second cylinder rod that are in reverse telescopic cooperation. The end of the first cylinder rod is fixed to the top of the first support arm 10, and the end of the second cylinder rod is fixed to the top of the second support arm.

[0040] When the first and second cylinder rods retract into the double-headed cylinder body 16, the first gripper plate 6 and the second gripper plate 13 are coplanar and thus side by side, making it easy to extend into the space between the two bricks.

[0041] When the first and second cylinder rods extend out of the double-headed cylinder body 16, the first and second gripper mechanisms move horizontally in opposite directions, causing the first gripper plate 6 and the second gripper plate 13 to move away from each other. The first gripper plate 6 and the adjacent second gripper plate 13 clamp the brick located between them, thus completing the gripping action. At the same time, the distance of the extension of the first and second cylinder rods is adapted to the spacing between the bricks, so that the spacing between the bricks can be maintained after gripping, and the bricks can be evenly spaced after being put down, which meets the stacking requirements of the kiln.

[0042] The mobile module can adopt a multi-axis robotic arm structure or a gantry structure.

[0043] If a multi-axis robotic arm structure is adopted, since this palletizing only requires lifting and translation, a three-axis robotic arm can meet the requirements. The end of the robotic arm is used to install on the base at the top of the base frame 1 to complete the movement.

[0044] If a gantry structure is adopted, it includes a gantry with a ground rail at its bottom, allowing the gantry to move in a straight line along the ground rail. A linearly translating overhead rail is installed on the gantry, and a linearly translating trolley is installed on the overhead rail. The translating direction is perpendicular and horizontal to the ground rail direction. A lifting frame capable of being raised and lowered is installed on the translating trolley, and the bottom of the lifting frame is used for mounting to the base, realizing the transfer action based on three-axis movement (gantry movement - trolley translating - lifting).

[0045] The equipment designed for the above-mentioned transfer actions is based on common structures in existing technologies. The details are not limited to the above description and can be referenced and replaced by various existing gantry cranes and robotic arm equipment.

[0046] This system achieves batch, equally spaced gripping capability through improvements to the gripper section. The equally spaced first gripper plate 6 and second gripper plate 13, driven by the reverse stroke of the first and second cylinder rods, can bring the first gripper plate 6 and second gripper plate 13 in the same row together or separate. When separated, they can cooperate with adjacent first gripper plate 6 or second gripper plate 13 to achieve a clamping effect on the bricks, thus enabling batch and equally spaced gripping and placement. After placement, the bricks naturally have equal and uniform spacing, without size errors. This ensures spacing accuracy and significantly improves palletizing efficiency through batch operations.

[0047] Regarding the quantity of bricks to be stacked, they can be pre-placed manually or prepared using a sorting and conveying system. Since the bricks being demolded in batches are arranged in a matrix with spacing between them, it's best to utilize this characteristic of the process by directly grasping and moving the demolded bricks to achieve the most efficient and process-saving operation. Of course, it's important to understand the specific application methods and not be limited by the methods described in this example.
