Description

Technical Field

[0001] The invention relates to the technical field of aerated concrete pallet alignment devices, and in particular to an automatic alignment device for an aerated concrete pallet. Background Art

[0002] Aerated concrete blocks are lightweight porous silicate products made from siliceous materials (sand, fly ash and silicon-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with gas-generating agents (aluminum powder), and made through processes such as batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing. Because they contain a large number of uniform and tiny pores after aeration, they are called aerated concrete blocks. With the rapid development of society, people pay more and more attention to environmental protection. Aerated concrete block products, as a new type of environmentally friendly building material, have been favored by more and more people. The use and movement of pallets are indispensable in the packaging process of aerated concrete blocks. When packaging, the aerated concrete blocks are stacked on the pallet rack, and then the conveyor chain on the conveyor drives the pallet rack at the top of the conveyor chain to move to the designated position at the end of the conveyor, and then the aerated concrete blocks on the pallet rack are packaged.

[0003] In the prior art, when performing packaging operations, after the pallet rack moves to the designated position at the end of the conveyor, in order to facilitate subsequent packaging operations, the operator is required to move the pallet rack to align the pallet rack. This manual alignment method not only consumes the labor of the operator, but also reduces the alignment efficiency of the pallet rack, affecting the packaging progress of the aerated concrete block products on the pallet rack. For this reason, we propose an automatic alignment device for aerated concrete pallets. Summary of the invention

[0025] Example 1

[0026] See also Figure 1-Figure 7The present invention provides a technical solution: an automatic alignment device for aerated concrete pallets, comprising a conveying frame 100, two groups of rotating gears 103 rotatably arranged on the conveying frame 100, and a conveying chain 102 sleeved and meshed with the rotating gears 103. A sensor is installed at the right end of the conveying frame 100, and the sensor is connected to a hydraulic rod 207. The conveying chain 102 can drive a pallet frame 101 for conveying. A pallet frame 101 is arranged on the top of the conveying chain 102. The pallet frame 101 is formed by crossing and welding a plurality of groups of square tubes to form a pallet frame 101. Aerated concrete blocks are stacked on the pallet frame 101. The conveying frame 100 is provided with two groups of position limiting alignment mechanisms for aligning the pallet frame 101.

[0027] The limit alignment mechanism includes two groups of arc plates 201, a track 206 and a cross plate 200. A clamping plate 202 is fixedly arranged on the top of the arc plate 201. The pallet rack 101 on the conveying chain 102 can be limited and aligned through multiple clamping plates 202. Two groups of T-shaped slide plates 213 are slidably arranged inside the track 206. Two groups of mounting plates 210 are fixedly arranged on the T-shaped slide plates 213. When the T-shaped slide plates 213 slide in the track 206, the mounting plates 210 are driven to move, thereby driving the arc plates 201 and The clamping plate 202 moves accordingly, and the bottom of the arc plate 201 extends between the two sets of mounting plates 210. A rotating shaft 214 is rotatably provided on the mounting plate 210, and the arc plate 201 and the T-shaped slide plate 213 can be rotated by the rotating shaft 214. The end of the rotating shaft 214 passes through the interior of the arc plate 201. A vertical column 203 is fixedly provided at the bottom of the arc plate 201, and the arc plate 201 can be connected and fixed to the stud 204 below by the vertical column 203. The stud 204 is fixedly provided at the bottom of the vertical column 203.

[0028] A moving groove 212 is provided inside the horizontal plate 200, and the bottom of the stud 204 passes through the moving groove 212. Two sets of locking thread rings 209 are connected to the outside of the stud 204 through threads, and the locking thread rings 209 can fix the stud 204 and the horizontal plate 200 together;

[0029] The track 206 is fixed on the surface of the conveying frame 100, and the track 206 is fixed on the conveying frame 100 by a first bolt, and the connecting plate 208 is fixed on the conveying frame 100 by a second bolt, and the clamping plate 202 contacts the surface of the pallet frame 101, and multiple groups of clamping plates 202 contact the front and back of the pallet frame 101, so as to clamp and limit the pallet frame 101, so that the pallet frame 101 is aligned to a specified position;

[0030] Two groups of connecting plates 208 are fixedly arranged at the bottom of the conveying frame 100, and two groups of vertical plates 211 are fixedly arranged on the surface of the connecting plates 208. A hydraulic rod 207 is rotatably arranged on the vertical plates 211 through a rotating column. The curved plate 201 and the clamping plate 202 can be driven to rotate by the hydraulic rod 207, and the working end of the hydraulic rod 207 extends to the surface of the horizontal plate 200.

[0031] The present invention adopts the designed limiting and aligning mechanism. When the pallet rack 101 located on the conveying chain 102 is conveyed to the right end of the conveyor, the hydraulic rod 207 drives the arc plate 201 and the clamping plate 202 to rotate, so that the clamping plate 202 contacts and limits and aligns the pallet rack 101, so that the pallet rack 101 is located at a specified position in the conveyor, thereby realizing automatic alignment of the pallet rack 101, and the pallet rack 101 can be continuously clamped during the packaging process to avoid displacement of the pallet rack 101, thereby facilitating the packaging operation of the aerated concrete blocks on the pallet rack 101.

[0032] When in use, the pallet rack 101 is located at the left end of the conveyor, and the aerated concrete blocks are stacked on the pallet rack 101. Then, the device for driving the conveyor chain 102 to rotate is started, and the conveyor chain 102 is driven to rotate and convey the pallet rack 101 to move. Then, when the pallet rack 101 moves to the right to a suitable position, it stops moving. At this time, the sensor detects the pallet rack 101, and the sensor converts the detected information into an electrical signal and transmits it to the control device. The hydraulic rod 207 is started by the control device, and then the working end of the hydraulic rod 207 extends outward, driving the cross plate 200, the stud 204, the vertical column 203, the arc plate 201 and the clamping plate 202 to rotate. Then the clamping plate 202 contacts and clamps the pallet rack 101. At this time, the pallet rack 101 can be limited and aligned, and in the subsequent packaging operation, the pallet rack 101 can also be clamped and limited by the clamping plate 202 to prevent the pallet rack 101 from being displaced. When the packaging is completed, the pallet rack 101 can be removed according to the above-mentioned reverse principle.

[0033] Example 2

[0034] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7A moving part for moving the stud 204 is arranged between the bottoms of the two groups of studs 204, and the moving part includes a bidirectional screw rod 300, on which there are two sections of threads with different rotation directions, namely, a right-handed thread and a left-handed thread, and two groups of nut seats 303 are respectively located on the right-handed thread and the left-handed thread, and the bidirectional screw rod 300 is fixed inside the bearing 302, and two groups of nut seats 303 are arranged outside the bidirectional screw rod 300, through which the rotary motion of the bidirectional screw rod 300 can be converted into linear motion, thereby driving the T-shaped slide plate 213 to slide to the left or right in the track 206, and the top of the nut seat 303 is fixed to the bottom of the stud 204;

[0035] Two sets of retaining rings 304 are also fixedly mounted on the outside of the bidirectional screw rod 300, and the retaining rings 304 can be used to limit the nut seat 303 on the bidirectional screw rod 300, so that the nut seat 303 is detached from the bidirectional screw rod 300. An L-shaped plate 301 is fixedly arranged on the cross plate 200, and the side view of the L-shaped plate 301 is an L-shaped structure, which can not affect the movement of the stud 204 in the movable groove 212 in the cross plate 200. A bearing 302 is embedded in the inside of the L-shaped plate 301, and the bearing 302 can both support the bidirectional screw rod 300 and facilitate the rotation of the bidirectional screw rod 300. The end of the bidirectional screw rod 300 passes through the inside of the bearing 302.

[0036] The present invention has a designed moving part. When a pallet rack 101 of other lengths is placed on the conveying chain 102, the two sets of nut seats 303 on the two-way screw rod 300 are moved in opposite directions or away from each other by rotating the two-way screw rod 300, thereby driving the arc plate 201 and the clamping plate 202 to move, so that the clamping plate 202 can be clamped and aligned according to the pallet racks 101 of different lengths, which is convenient for operation.

[0037] During use, when pallet racks 101 of different lengths are placed on the conveyor chain 102, the spacing between the two sets of clamping plates 202 is adjusted. When adjusting, first loosen the two sets of locking threaded rings 209 on the studs 204 by turning them outward, and then turn the bidirectional screw rod 300. At this time, the two sets of nut seats 303 located outside the bidirectional screw rod 300 move in the direction toward or away from each other, thereby driving the two sets of arc plates 201 and the clamping plates 202 to move. At this time, the T-shaped slide plate 213 will slide in the track 206 and the stud 204 will move in the moving groove 212. When the movement is adjusted, tighten the two sets of locking threaded rings 209 on the studs 204 to adjust the spacing between the two sets of clamping plates 202, which is convenient for adjustment.

[0038] In this embodiment, a plurality of groups of support columns are fixedly provided at the bottom of the conveying frame 100, and the support columns are fixedly connected to the conveying frame 100 by welding. A rotating rod is fixedly provided inside the rotating gear 103. The driving device drives the rotating rod to rotate, thereby driving the rotating gear 103 to rotate, thereby driving the conveying chain 102 to rotate, and both ends of the rotating rod pass through the interior of the conveying frame 100. During use, the rotating rod and the conveying frame 100 are rotationally connected.
