Description

Technical Field

[0001] The invention belongs to the technical field of building material processing equipment, and in particular relates to aerated brick stacking equipment and aerated brick stacking method. Background Art

[0002] Aerated bricks, also known as aerated concrete blocks, are lightweight, offer excellent thermal insulation, strong seismic resistance, easy workability, high-temperature resistance, excellent sound insulation, and strong adaptability. They are widely used in construction as wall materials, infill walls, floor slabs, and roof panels.

[0003] Aerated bricks are all rectangular. When stacked, each layer of aerated bricks is arranged in two layers along the length, 6 to 8 along the width, and 6 to 8 layers along the height. For the sake of convenience, in this patent application, the X-axis of the three-dimensional coordinates of the brick stack represents the horizontal direction (left-right direction), the Y-axis represents the vertical direction (front-back direction), and the Z-axis represents the height direction (up-down direction).

[0004] In the existing technology, each brick stack is equipped with a pallet for packaging, which is convenient for the forklift to insert the two forks into the pallet for loading and unloading operations. Pallets for short-distance transportation can be returned to the factory for reuse, but the return transportation cost for long-distance transportation is very high, which increases the transportation cost of aerated bricks.

[0005] To reduce the packaging and transportation costs of aerated bricks, some aerated brick manufacturers are starting to avoid using pallets. Instead, they are stacking aerated bricks with two fork holes in the second-to-last layer of the stack. However, existing aerated brick stacking equipment lacks these holes and often requires manual operation, resulting in low efficiency and unsuitable for automated mass production. Summary of the Invention

[0006] The purpose of the present invention is to overcome the problems existing in the above-mentioned prior art and provide an aerated brick stacking device. When stacking aerated bricks, it can leave fork holes on the brick stack, so as to realize fully mechanized stacking.

[0007] Another object of the present invention is to use the device to provide a method for stacking aerated bricks, which has simple operating steps and high work efficiency.

The bottom of the brick clamp is connected to a rotary drive device, and the bottom of the rotary drive device is connected to a brick clamp; the brick clamp includes a four-sided frame consisting of a front slide, a rear slide, a left beam and a right beam, and brick clamping arms installed in the front slide and the rear slide are respectively provided on the left and right sides of the four-sided frame. The two brick clamping arms are each driven by a clamping arm oil cylinder to translate along the front slide and the rear slide, and an elastic brick stack plywood is provided on the middle and upper part of the inner side of the brick clamping arm, and a rubber pad is provided on the inner lower end of the brick clamping arm; the middle and lower part of the inner side of the brick clamping arm is hinged to the fork hole brick plywood through four connecting rods, and the fork hole brick plywood is connected to the plywood cylinder that drives it to rise and fall, and rubber blocks for clamping the fork hole bricks are provided on the front and rear ends of the inner side of the fork hole brick plywood.

[0009] Preferably, the brick clamping arm includes an L-shaped front arm plate and an L-shaped rear arm plate, the L-shaped front arm plate is composed of a front horizontal plate and a front vertical plate, the L-shaped rear arm plate is composed of a rear horizontal plate and a rear vertical plate, a horizontal plate beam is connected between the front horizontal plate and the rear horizontal plate, a plurality of vertical plate beams are connected between the front vertical plate and the rear vertical plate, an upper connecting rod shaft and a lower connecting rod shaft are connected in the middle and lower parts between the front vertical plate and the rear vertical plate, the upper connecting rod shaft is hinged at the other end of the two connecting rods at the upper part of the fork hole brick clamping plate, and the lower connecting rod shaft is hinged at the other end of the two connecting rods at the lower part of the fork hole brick clamping plate.

[0010] Preferably, a plurality of rollers embedded in the front slide grooves are installed on the inner side of the front transverse plate, and a plurality of rollers embedded in the rear slide grooves are installed on the inner side of the rear transverse plate.

[0011] Preferably, a brick blocking rod is connected to the front or rear side of the lower portion of the two brick clamping arms, one end of the brick blocking rod is fixedly connected, and the other end of the brick blocking rod is slidably connected through a sleeve.

[0012] The second object of the present invention is achieved in this way:

[0013] A method for stacking aerated bricks using the above-mentioned equipment comprises the following steps:

[0014] In the first step, the aerated bricks transported from the workshop are placed on the first brick loading platform in a row with two bricks in the length direction, with the length direction of the aerated bricks being horizontal;

[0015] In the second step, the stacking fixture clamps two layers of aerated bricks on the first brick loading platform and moves them to the conveyor chain, with the length direction of the aerated bricks being horizontal;

[0016] In the third step, the stacking fixture clamps the four aerated bricks at the two fork holes on the top of the two layers of aerated bricks on the conveyor chain and transfers them to the second brick loading platform. The length direction of the four aerated bricks is horizontal.

[0017] The fourth step is that the stacking fixture clamps 6 to 8 layers of aerated bricks on the first brick loading platform and transfers them to the top of the two layers of aerated bricks on the conveyor chain. During the transfer process, the stacking fixture rotates 90 degrees so that the length direction of the 6 to 8 layers of aerated bricks is vertical;

[0018] Step 5: The stacking fixture releases the brick clamping arm and rises. The brick clamping arm holds the top two layers of aerated bricks and then rises to a certain height. The conveyor chain starts to move the stacked bricks to the next brick stack. The stacking fixture descends and places the two layers of aerated bricks it holds on the conveyor chain. During the descent, the stacking fixture rotates 90 degrees so that the length direction of the two layers of aerated bricks it holds is horizontal.

[0019] The sixth step is to repeat the third to fifth steps. After every three or four steps, aerated bricks with 2 pieces in the horizontal length direction and 6 or 8 pieces in the vertical width direction are accumulated on the second brick loading platform. The second brick loading platform moves forward, and the stacking fixture is moved to the second brick loading platform and lowered. When the brick blocking rod drops to the middle of the aerated bricks on the second brick loading platform, the second brick loading platform moves backward. In the process of the second brick loading platform moving backward, the aerated bricks that are loosely arranged vertically are brought together under the blocking effect of the brick blocking rod on the stacking fixture. The aerated bricks that are brought together are then picked up by the stacking fixture. They are stacked layer by layer. When the number of aerated brick stacks reaches 6 to 8 layers, in the fourth step, the brick stack is not clamped from the first brick loading platform, but 6 to 8 layers of aerated bricks are clamped from the second brick loading platform and transferred to the top of the two layers of aerated bricks on the conveyor chain.

[0020] The advantages of the present invention are:

[0021] (1) The aerated brick stacking equipment of the present invention includes a control panel, an elevated track, a first brick loading platform, a second brick loading platform, a conveyor chain and a stacking fixture. The equipment is complete and well-positioned, and the stacking operation of aerated bricks can be completed.

[0022] (2) The stacking fixture of the present invention includes a translation frame driven by a motor, vertical slides are respectively provided on the front and rear sides of the translation frame, a lifting frame driven by a front lifting cylinder and a rear lifting cylinder is provided between the two vertical slides, a rotary drive device is connected below the lifting frame, and a four-sided frame consisting of a front slide, a rear slide, a left beam and a right beam is connected below the rotary drive device; it can complete the translation, lifting and rotation operations of the stacking fixture, and has a reasonable structure and stable operation;

[0023] (3) The brick clamping arms are respectively arranged on the left and right sides of the four-sided frame of the present invention and are installed on the front slide and the rear slide. The two brick clamping arms are each driven by a clamping arm oil cylinder to move horizontally along the front slide and the rear slide. The clamping arm oil cylinder drives the two brick clamping arms to clamp and release. The brick clamping arms have a reasonable structure, stable operation and strong clamping force.

[0024] (4) The middle and lower parts of the inner side of the brick clamping arm of the present invention are hinged to the fork hole brick clamping plate through four connecting rods. The fork hole brick clamping plate is connected to the clamping plate oil cylinder that drives it to rise and fall. The front and rear ends of the inner side of the fork hole brick clamping plate are provided with rubber blocks for clamping the fork hole bricks. When it is necessary to clamp the fork hole bricks, the clamping plate oil cylinder drops the fork hole brick clamping plate. When the two brick clamping arms perform the clamping action, the two protruding rubber blocks of the fork hole brick clamping plate just clamp the four bricks at the fork hole position. This design cleverly combines the functions of clamping brick stacks and fork hole bricks, simplifies the stacking operation steps, and improves work efficiency.

[0025] (5) The present invention connects the brick blocking rod to the lower front side of the two brick clamping arms, and combines it with the movement operation of the second brick loading platform to bring the vertically loosely arranged aerated bricks together, thus solving the problem of secondary arrangement of the fork hole bricks.

[0026] (6) The method for stacking aerated bricks of the present invention has the advantages of simple method, clear structure, easy operation, short equipment travel and high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
