Description

Technical Field

[0001] The invention relates to the technical field of brick conveying and sorting, and in particular to an automatic conveying and stacking device for lightweight hollow bricks. Background Art

[0002] Lightweight hollow bricks are bricks with a light weight and a cavity structure inside. The main raw materials include natural minerals, industrial waste residues, etc., and are processed through a specific process. They are widely used in the construction industry because of their light weight, thermal insulation, sound absorption, environmental protection and energy saving, excellent seismic performance and convenient construction.

[0003] During the production of lightweight hollow bricks, the specified amount of raw materials must first be selected according to the production formula and mixed. The hollow bricks are then pressed and removed. The hollow bricks are then cured and finally stacked for storage or transportation (see Figure 7 ).

[0004] In the current stacking and conveying process, each hollow brick is stacked on the bottom wooden frame manually, and the hollow bricks are in close contact with each other. Then, the wooden frame and the hollow bricks on the wooden frame are transported to the designated location by external forklifts and other equipment. The current transportation and stacking process has the following problems: 1. Although lightweight hollow bricks are light in weight, they are generally large in size. During manual transportation and stacking, usually only one brick can be transported at a time, and the brick stacks need to be stacked up and down. The work efficiency of stacking by manpower is low, and the stacking is difficult. It is difficult to strictly control the specific position of each hollow brick during manual stacking, and it is easy for a certain hollow brick to deviate from the position and affect the stability of the entire brick stack.

[0005] 2. When stacking bricks manually, hollow bricks are usually stacked from top to bottom, which makes it difficult to control the gaps between bricks.

[0019] In summary, the present invention includes at least one of the following beneficial effects: First, in the present invention, hollow bricks are first placed in the conveying equipment manually, and the conveying equipment transports multiple hollow bricks to the placement slot, and then the position of the column of hollow bricks is limited by the clamping mechanism and the column of bricks is internally supported, and then each layer of hollow bricks is staggered and stacked by the stacking unit, and a single stacking process is realized by a reciprocating movement of the stacking plate. During the whole stacking process, the clamping mechanism always maintains the clamping and limiting position of the hollow bricks, ensuring the accurate stacking position of the hollow bricks, avoiding the problem that the position deviation of a certain hollow brick affects the stability of the overall brick stack, and secondly, through the above method, it is convenient to stack the hollow bricks from top to bottom, reducing manual participation and improving the stacking efficiency of hollow bricks.

[0020] 2. In the present invention, during the process of the stacking board moving downward for stacking, the offset column moves from the vertical section of the corresponding offset groove to the inclined section, and the stacking board drives the hollow bricks thereon to move to the left during the downward movement. Therefore, during the placement process, the hollow bricks in this column are pressed against the reference plate on the left by the displacement to the left. Secondly, when the above process is repeated to place hollow bricks in different columns of the same layer, the hollow bricks in this column are pressed against the adjacent left column of hollow bricks through the above process, thereby ensuring the compact placement of the hollow bricks in this layer, improving the stability of the subsequent brick stacks, and avoiding the influence of the stability of the brick stacks and the occurrence of safety problems due to the large gaps between the brick stacks.

[0021] 3. The two L-shaped plates in the same clamping assembly of the present invention are respectively pressed against the two diagonal points of the inner cavity of the hollow brick, and finally the driving plate is pressed against the corresponding two rectangular plates. The driving plate, the two rectangular plates and the L-shaped plate jointly form a triangular stable clamping, which improves the stability of the internal support clamping inside the hollow brick, and avoids the problem of hollow bricks falling during movement. At the same time, the internal support clamping method facilitates the subsequent stacking of hollow bricks, and avoids the external clamping that causes gaps between adjacent hollow bricks when the hollow bricks are subsequently stacked, thereby affecting the stability of the entire brick stack.

[0022] Fourth, in the present invention, during the stacking process after the offset, the guide pillars are inserted into the guide grooves on the corresponding reference plates to limit and guide the front and rear directions of the stacking plates, thereby improving the stability of the stacking plates when they are moved down to place hollow bricks.

[0023] 5. In the present invention, during the forward movement of the stacking plate, the engagement between the rack 2 and the gear 2 at different positions causes the base plate and the placement plate to rotate synchronously by ninety degrees, and then the hollow bricks of this layer are stacked. The above operation is repeated to achieve cross-vertical stacking of the hollow bricks, thereby improving the overall stability of the brick stack. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, an automatic conveying and stacking device for lightweight hollow bricks comprises: a U-shaped seat 1, the opening of the U-shaped seat 1 faces upward, a placing seat 2 is fixedly arranged on the upper end surface of the horizontal section of the U-shaped seat 1 through a fixing frame, a placing groove 3 for initially placing hollow bricks is opened on the upper end surface of the placing seat 2, lifting blocks 4 are arranged on the opposite surfaces of the two vertical sections of the U-shaped seat 1 to slide up and down, the lifting blocks 4 are driven by an external hydraulic cylinder 1 (not shown in the figure) to move up and down, moving blocks 40 are arranged on the opposite surfaces of the two lifting blocks 4 to slide left and right, two support rods 41 distributed left and right and with axes extending from front to back are fixedly arranged between the two moving blocks 40, stacking plates 42 are arranged on the two support rods 41 to slide forward and backward together, and the stacking plates 42 are driven by an external hydraulic cylinder 2 (not shown in the figure) to move forward and backward.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, a clamping mechanism 5 is provided on the stacking plate 42, and the clamping mechanism 5 includes a vertical rod 50. A plurality of clamping assemblies equidistantly arranged from front to back are fixedly provided on the lower end surface of the stacking plate 42, and the clamping assemblies include two left-right symmetrical vertical rods 50. The vertical rods 50 are rotatably provided on the lower end surface of the stacking plate 42 and the axis extends from top to bottom. An L-shaped plate 500 for clamping the inner cavity of the hollow brick is provided on the lower side of the vertical rod 50. The clamping mechanism 5 also includes a clamping unit 51 provided on the stacking plate 42 and used for clamping multiple hollow bricks at the same time.

[0036] like Figure 1 and Figure 4 As shown, a stacking unit 6 located in front of a stacking plate 42 and used for stacking hollow bricks is provided on the horizontal section of the U-shaped seat 1, and the stacking unit 6 includes a base plate 60. The upper end surface of the U-shaped seat 1 is provided with a base plate 60 for sliding left and right. A rotating plate 600 is provided on the upper end surface of the base plate 60 for rotating through a rotating axis. The upper end surface of the rotating plate 600 is provided with a placement plate 601 for sliding up and down through two centrally symmetrical support columns with axes extending from bottom to top.

[0037] It should be noted that the hollow bricks are transported from left to right by an existing external conveying device such as a chain plate conveyor belt, and multiple hollow bricks are transported from left to right to the placement groove 3 on the placement seat 2. The placement groove 3 plays a role of preliminary limit guidance for multiple hollow bricks, which is convenient for subsequent clamping and stacking operations. When working, the wooden frame for stacking hollow bricks is first placed on the placement plate 601. When multiple hollow bricks are transported to the placement groove 3 on the placement seat 2 in a front-to-back manner, the external hydraulic cylinder works to make the lifting block 4 drive the stacking plate 42 to move downward synchronously. During the downward movement of the stacking plate 42, the clamping mechanism 5 Two L-shaped plates 500 in the same clamping assembly are inserted into the cavity of the hollow brick and are stretched and clamped internally. At the same time, the clamping unit 51 clamps and fixes the corresponding multiple hollow bricks in the left and right directions and the front and back directions. Finally, the above-mentioned multiple hollow bricks are closely aligned in a row. After that, the external hydraulic cylinder 1 and the external hydraulic cylinder 2 work synchronously to make the stacking plate 42 drive the clamped multiple hollow bricks to move to the top of the placement plate 601. The stacking unit 6 guides the multiple hollow bricks to be stacked on the wooden frame on the placement plate 601. At the same time, the stacking unit 6 makes each layer of hollow bricks staggered. After the stacking is completed, the wooden frame and the hollow bricks thereon are removed.

[0038] like Figure 2 and Figure 3As shown, the clamping unit 51 includes a driving rod 510, and the lower end surface of the stacking plate 42 is rotatably provided with a driving rod 510 whose axis extends from front to back through two front-to-back symmetrical fixing plates, and the driving rod 510 is connected to an external motor (not shown in the figure), and two front-to-back symmetrical thread grooves 511 with opposite thread directions are provided on the driving rod 510, and a T-shaped plate 512 corresponding to the thread groove 511 is slidably provided front and back on the lower end surface of the stacking plate 42, and the T-shaped plate 512 is threadedly matched with the corresponding thread groove 511, and the horizontal section of the T-shaped plate 512 is slidably provided with a clamping plate 513 through two sliding rods extending from front to back through two axes, and the two clamping plates 513 are located between the two T-shaped plates 512, and a spring 514 sleeved on the sliding rod is fixedly provided between the clamping plate 513 and the T-shaped plate 512.

[0039] like Figure 2 and Figure 3 As shown, the clamping unit 51 also includes a clamping plate 515, and the upper end surface of the placement seat 2 is fixedly provided with the clamping plate 515. A plurality of movable rods 516 that are equidistantly arranged from front to back and whose axes extend from top to bottom are penetrated through the stacking plate 42 for sliding up and down. A clamping plate 517 located on the left side of the clamping plate 515 is fixedly provided on the lower end surfaces of the plurality of movable rods 516. The clamping plate 517 is composed of a vertical section and an inclined section that is inclined to the left from top to bottom, respectively.

[0040] like Figure 2 and Figure 3 As shown, the clamping unit 51 also includes a second spring 518, and a second spring 518 mounted on the movable rod 516 is fixedly arranged between the second clamping plate 517 and the stacking plate 42. An L-shaped strip 519 is fixedly arranged on the left end face of the moving block 40 through a connecting column, and the upper end face of the L-shaped strip 519 is located above the movable rod 516, and the front end face of the horizontal section of the L-shaped strip 519 is chamfered.

[0041] During operation, after a plurality of hollow bricks are transported from left to right in a row to the placement slot 3 on the placement seat 2, the external hydraulic cylinder 1 works to move the stacking plate 42 downward. During the downward movement of the stacking plate 42, the second clamping plate 517 thereon is driven to move downward synchronously, and the L-shaped bar 519 moves downward synchronously. At this time, the movable rod 516 is pressed by the L-shaped bar 519, that is, the second clamping plate 517 and the movable rod 516 are limited and fixed at this time, and the second clamping plate 517 moves downward synchronously with the stacking plate 42. The inclined section of the second clamping plate 517 first contacts the left side of the corresponding plurality of hollow bricks. And squeeze the hollow brick to move right, finally the vertical section of the second clamping plate 517 is tightly against the left end face of the hollow brick, and the right end face of the hollow brick is tightly against the first clamping plate 515, and the preliminary limitation of the left and right directions of the column of hollow bricks is completed through the cooperation between the first clamping plate 515 and the second clamping plate 517, which is convenient for the subsequent clamping process. It should be noted that in the subsequent process of clamping the hollow bricks forward, the movable rod 516 moves forward synchronously and is staggered with the L-shaped bar 519, so that the movable rod 516 can move up and down in the subsequent placement process to avoid the stacking process.

[0042] The stacking plate 42 continues to move downward, so that the two clamping plates 513 are respectively located on the front and rear sides of the column of hollow bricks, and the L-shaped plate 500 moves to the cavity of the corresponding hollow brick. The external motor drives the driving rod 510 to rotate synchronously. The threaded cooperation between the two T-shaped plates 512 on the driving rod 510 and the corresponding threaded groove 1 511 makes the two T-shaped plates 512 drive the clamping plates 513 thereon to move synchronously, and the two T-shaped plates 512 approach each other. After the T-shaped plate 512 drives the clamping plates 513 thereon to stick to the front and rear sides of the column of hollow bricks, the clamping plates 513 stop moving, and the spring 1 514 is compressed. As the driving rod 510 continues to rotate, the T-shaped plate 512 continues to move, and at the same time, the spring 1 514 is continuously compressed to increase the force of the clamping plates 513 clamping the column of hollow bricks, thereby achieving the front and rear clamping of the column of hollow bricks, so that the column of hollow bricks is compactly arranged, which is convenient for subsequent picking and placing processes.

[0043] like Figure 2 and Figure 3 As shown, the clamping mechanism 5 also includes a rectangular plate 52, and the lower end surface of the vertical rod 50 is fixedly provided with a rectangular plate 52, and two clamping rods 520 symmetrical about the axis of the vertical rod 50 are slidably provided on the rectangular plate 52, and one end of the clamping rod 520 away from the rectangular plate 52 is hinged to the corresponding L-shaped plate 500, and a driving group 53 is provided on the stacking plate 42.

[0044] like Figure 2 and Figure 3As shown, the driving group 1 53 includes a driving plate 531, and the driving rod 510 is provided with a thread groove 2 530 corresponding to the clamping assembly one by one. A driving plate 531 corresponding to the thread groove 2 530 and in a T shape is slidably arranged in front and back of the lower end surface of the stacking plate 42, and the driving plate 531 is threadedly matched with the corresponding thread groove 2 530. Two left-right symmetrical driving strips 532 are fixedly arranged on the upper end surface of the horizontal section of the driving plate 531. The left driving strip 532 is a horizontal section and an inclined section inclined to the left from back to front from back to front. A gear 1 533 is rotatably sleeved on the vertical rod 50, and a rack 1 534 meshing with the gear 1 533 is fixedly sleeved on the clamping rod 520. A matching rod 535 whose axis extends from bottom to top and matches with the corresponding driving strip 532 is fixedly arranged on the two racks 1 534 on the front side of the same group of clamping assemblies.

[0045] It should be noted that initially, the two corresponding rectangular plates 52 in the same clamping assembly are symmetrical with each other, and the two are arranged in a V-shape with the opening facing backward. During the continuous rotation of the above-mentioned driving rod 510, the threaded cooperation between the second thread groove 530 and the driving plate 531 causes the multiple driving plates 531 to move forward synchronously, and the driving plate 531 drives the driving bar 532 thereon to move synchronously. The inclined section of the driving bar 532 pushes the matching rod 535 to make the corresponding rack 1 534 move synchronously, and the meshing between the rack 1 534 and the gear 1 533 causes the other rack 1 534 to move synchronously. Therefore, the two racks 1 534 both drive the abutting rod 520 thereon to move synchronously, and the two L-shaped plates 500 corresponding to the same driving rod 510 move away from each other. In this process, the rectangular plate 52 drives the corresponding two L-shaped plates 500 to rotate adaptively, and the two L-shaped plates 500 in the same clamping assembly are respectively pressed against the two diagonal points of the inner cavity of the hollow brick, and finally the driving plate 531 is pressed against the corresponding two rectangular plates 52, and the inner expansion clamping of the two cavities in the same hollow brick is completed in the above manner. In addition, the driving plate 531, the two rectangular plates 52 and the L-shaped plate 500 jointly form a triangular stable clamping, which improves the stability of the inner expansion clamping of the hollow brick and avoids the problem of hollow bricks falling during movement. At the same time, the internal expansion clamping method is adopted to facilitate the subsequent stacking of hollow bricks, and avoid the gap between adjacent hollow bricks after the subsequent stacking of hollow bricks due to external clamping, which affects the overall stability of the brick stack.

[0046] like Figure 1 , Figure 5 and Figure 6As shown, the stacking unit 6 also includes a reference plate 61, and two reference plates 61 that are perpendicular to each other and slide through the placement plate 601 are fixedly arranged on the rotating plate 600. The opposite surfaces of the two vertical sections of the U-shaped seat 1 are provided with offset grooves 610, and the offset grooves 610 are divided into a vertical section and an inclined section inclined to the left from top to bottom from top to bottom. The lower end surface of the moving block 40 is fixedly provided with an offset column 611 located in the offset groove 610 through a vertical bar.

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, the stacking unit 6 also includes a guide column 62, and two guide columns 62 arranged symmetrically front and back are fixedly provided on the lower end surface of the stacking plate 42. Two left-right symmetrical guide grooves 620 are provided on the upper end surface of the reference plate 61, and the lateral distance between the guide column 62 and the guide groove 620 on the left reference plate 61 is the same as the lateral offset distance of the offset groove 610.

[0048] like Figure 1 and Figure 5 As shown, the stacking unit 6 also includes a rotating group 63, and the rotating group 63 includes a gear 2 630. The lower end surface of the placement plate 601 is fixedly provided with a gear 2 630 through a central axis whose axis is colinear with the axis of the rotating shaft. The rear end surface of the base plate 60 is slidably provided with a push rod 631 whose axis extends from front to rear through an L-shaped frame, and the front end surface of the push rod 631 is fixedly provided with a plurality of racks 2 632 arranged in sequence from top to bottom through a T-shaped frame.

[0049] like Figure 1 , Figure 5 and Figure 7 As shown, the rotating group 63 also includes a connecting frame 633, and the right end surface of the stacking plate 42 is fixedly provided with the connecting frame 633, and a pushing plate 634 for pushing the pushing rod 631 is fixedly provided on the connecting frame 633, and a spring 635 mounted on the pushing rod 631 is fixedly provided between the T-shaped frame and the L-shaped frame.

[0050] During operation, after the stacking plate 42 has clamped a row of hollow bricks, the external hydraulic cylinder 1 and the external hydraulic cylinder 2 cooperate to make the stacking plate 42 rise first and then move forward to just above the placement plate 601, and then the stacking plate 42 drives the hollow bricks thereon to move downward. During the downward movement of the stacking plate 42, the moving block 40 and the offset column 611 move synchronously, and the offset column 611 moves from the vertical section corresponding to the offset groove 610 to the inclined section. When the offset column 611 moves in the inclined section of the offset groove 610, the stacking plate 42 drives the hollow bricks thereon to move downward. At the same time, it moves to the left, so the hollow bricks in this row are pressed against the reference plate 61 on the left side. When the above process is repeated to place hollow bricks in different rows of the same layer, the displacement of the stacking plate 42 to the left during the downward movement makes the hollow bricks in this row close to the hollow bricks in the adjacent row, ensuring that the hollow bricks in this layer are placed compactly, improving the stability of the subsequent brick stacks, avoiding the stability of the brick stacks due to excessive gaps between the brick stacks, and even causing safety problems. When the hollow bricks are placed on the wooden frame on the placement plate 601, the external motor works to reverse the drive rod 510.

[0051] In the stacking process of moving downward and leftward to place the hollow bricks on the wooden frame on the placement plate 601, the guide column 62 is inserted into the guide groove 620 on the corresponding reference plate 61 to limit the front and rear directions of the stacking plate 42 and improve the stability of the stacking process.

[0052] In the above process of placing hollow bricks on the same layer, it should be noted that after completing the placement of a row of hollow bricks, the external hydraulic cylinder three drives the base plate 60 and the placement plate 601 to move left synchronously by a specified distance, and then places another row of hollow bricks on the same layer. After repeating the above operation to complete the stacking operation of one layer of hollow bricks, the external hydraulic cylinder four works to make the placement plate 601 move down a specified distance, and repeat the stacking operation of the next layer of hollow bricks. After the stacking is finally completed, the staff uses an external forklift to take out the wooden frame and the hollow bricks stacked thereon.

[0053] At the initial position, the rack 632 and the gear 630 are staggered up and down. After completing the stacking operation of one layer, the placement plate 601 moves down a specified distance. At this time, the gear 630 is aligned with the uppermost rack 632 up and down. Then, as the stacking plate 42 moves forward, the stacking plate 42 pushes the push rod 631 forward through the L-shaped frame and the push plate 634, and the push rod 631 drives the rack 632 on it to move forward synchronously. The engagement between the rack 632 and the gear 630 makes the rotating plate 600 and the placement plate 601 rotate 90 degrees synchronously, and then the hollow bricks of this layer are stacked again. Repeat the above operation so that the two adjacent layers of hollow bricks are staggered (see Figure 7 ), to improve the overall stability of the brick stack, after rotating 90 degrees, the reference plate 61 on the front side is initially rotated to the left side, serving as a reference for the stacking of this layer.
