Description

Technical Field

[0001] The present invention relates to the technical field of brick production, and particularly to a brick discharging and packing production line and a brick discharging and packing method. Background Art

[0002] When existing brick factories produce sintered bricks, the brick billets are stacked into stacks and fired in a brick kiln. The structure of the brick stack is as Figure 1 shown. In each layer of the brick stack 1, the bricks are adjacent to each other in the length direction, and in the thickness direction of the bricks, there is a certain distance 11 between them. The directions of the bricks in adjacent layers are perpendicular to each other, so that gaps are formed between the bricks in the brick stack, facilitating good heat absorption for each brick in the brick stack and ensuring the sintering quality of the bricks.

[0003] After the bricks are sintered, when discharging the bricks from the kiln, unpacking and packing them, it is necessary to re-organize and stack them. The traditional method is all completed by manual operation, which not only has a harsh working environment and high temperature, but also has a large labor intensity, low efficiency, and high labor cost. In recent years, some mechanized brick stack discharging equipment has also emerged. For example, the patent with the publication number CN103552832A discloses a brick discharging and stacking unit and a brick discharging and stacking method for sintered bricks, and the patent with the publication number CN110654879A discloses a full-automatic finished brick discharging, disassembling, transporting, forming a team, and packing complete set of equipment and method, etc. Although they can achieve mechanized brick stack discharging, the effect is not ideal. During the sintering process of sintered bricks, the phenomena of brick adhesion and brick stack deformation occur, which has always been a bottleneck problem difficult to break through in mechanized brick stack discharging and is a difficult problem that brick factories are eager to solve and urgently need to solve.

[0004] Based on years of experience in the processing, production, sales, and use of sintered bricks and their mechanical equipment, the applicant has innovated the brick discharging and packing production line and the brick discharging and packing method of this application. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a brick discharging and packing production line and a brick discharging and packing method with high brick discharging efficiency and good effect.

[0006] To solve the above technical problem, the present invention is realized through the following technical solutions:

[0007] A brick discharging and packing production line includes a brick stack conveying rack, a brick stack separating mechanism, a first brick receiving conveying rack, a second brick receiving conveying rack, a first brick feeding rack, a second brick feeding rack, and a brick stacking manipulator. The brick stack separating mechanism includes a column and multiple layers of brick stack separating chucks arranged on the column. Each layer of brick stack separating chuck is rotatably connected to the column. The brick stack separating chuck includes a clamping sleeve part. The clamping sleeve part of each layer of brick stack separating chuck is provided with a first clamping mechanism corresponding to the two ends of the brick and a second clamping mechanism corresponding to the two side surfaces of the brick. The clamping sleeve parts of each layer of brick stack separating chuck correspond up and down to form a brick stack separating sleeve.

[0008] When the bricks are packed, the brick stack conveyor rack conveys the brick stack to the stack splitting mechanism. The stack splitting mechanism first makes the clamping sleeves of each layer of stack splitting chucks correspond up and down to form a stack splitting sleeve, and then places the brick stack in the stack splitting sleeve. It can be that the brick stack remains stationary and the stack splitting sleeve moves downward from above the brick stack to cover the outside of the brick stack, or the stack splitting sleeve remains stationary and the brick stack rises from below the stack splitting sleeve through the lifting of the brick stack conveyor rack and enters the stack splitting sleeve, so that the clamping sleeve of each layer of stack splitting chuck corresponds to each layer of bricks of the brick stack. Then, the first clamping mechanism of each layer of stack splitting chuck first closes and clamps to clamp and straighten the two ends of the bricks in the brick layer, realizing stacking and supporting the stack. Then, the first clamping mechanism of the topmost layer of stack splitting chuck loosens, and the second clamping mechanism closes and clamps to gather the bricks in this brick layer, eliminate the gaps between the bricks, and clamp them. Then, the first clamping mechanism of this layer closes and clamps again, so as to clamp and rotate the topmost brick layer to one side. Then, in turn, the first clamping mechanism of the second layer of stack splitting chuck loosens, the second clamping mechanism closes and clamps, and the first clamping mechanism clamps again to clamp and rotate the second brick layer to the other side. From top to bottom, each layer of stack splitting chuck clamps the bricks in the corresponding brick layer and rotates them to the left and right sides respectively. Finally, the bricks on each stack splitting chuck on both sides of the stack splitting chuck are picked up by the first brick receiving conveyor rack and the second brick receiving conveyor rack respectively, and are correspondingly conveyed to the first brick conveying rack and the second brick conveying rack. The first brick conveying rack and the second brick conveying rack convey the bricks to the brick stacking manipulator for re-stacking and packing.

[0009] The stack splitting chuck includes a frame body, and a rotary fixing seat is arranged on the frame body. The frame body is rotatably connected to the column through the rotary fixing seat. The rotation of the stack splitting chuck is realized through the rotary fixing seat, so as to realize the transfer of the brick layer clamped by it to the conveying mechanism.

[0010] Specifically, the rotary fixing seat includes a rotary sleeve seat and a gear seat that is sleeved on the column and cannot rotate. A driving gear driven by a stepping motor is arranged on the frame body, and the driving gear meshes with the gear seat.

[0011] The gear seat is a sector gear seat, which can reduce the space occupation. A circular gear or toothed ring can also be used. The driving gear walks on the gear seat to drive the rotational movement of the stack splitting chuck, and the rotation angle is made more accurate through the stepping motor.

[0012] The rotary fixing seat also includes a lifting cylinder arranged below it. Through the lifting cylinder, the stack splitting chuck after clamping the brick layer can be lifted by a certain height, so that a certain gap is generated between the brick layers, avoiding the contact between the brick layers, reducing the frictional resistance, and at the same time, avoiding accidents such as brick dropping caused by the contact between the brick layers.

[0013] An adjusting counterweight is provided at one end of the frame body opposite to the jacket part. By adjusting the counterweight, the stacking gripper plate after gripping the brick layer can be kept balanced, which is not only convenient for driving rotation, but also avoids inclined friction between its rotating socket and the column, thus improving the service life.

[0014] A column sleeve that can slide up and down is sleeved on the column. The stacking gripper plate is arranged on the column sleeve through a rotating fixing seat, and the column sleeve is connected with a lifting and adjusting mechanism.

[0015] The lifting and adjusting mechanism is a lifting and adjusting counterweight, a lifting and adjusting hydraulic cylinder or a cylinder.

[0016] The lifting of the column sleeve is realized through the lifting and adjusting mechanism, and then the overall lifting of each stacking gripper plate is driven, so as to conveniently sleeved the stacking gripper plate outside the brick stack from the top of the brick stack. It is more convenient than the jacking of the brick stack, minimizes the movement of the brick stack, and better ensures the stability of the brick stack.

[0017] There are two columns, and the stacking gripper plates of each layer are arranged in a left-right cross pattern in sequence, so that the stacking gripper plates with the same brick gripping direction are located on the same column, and the two layers of bricks with perpendicular brick directions are distributed and gripped on two different columns, and then placed on different conveying mechanisms, reducing the load on a single column.

[0018] Both the first brick receiving and conveying rack and the second brick receiving and conveying rack are lifting brick receiving and conveying racks.

[0019] Brick pushing mechanisms are arranged at the brick discharging ends of the first brick receiving and conveying rack and the second brick receiving and conveying rack.

[0020] The brick pushing mechanism includes a lifting roller row and a brick pushing rack arranged at the brick discharging end of the first brick receiving and conveying rack or the second brick receiving and conveying rack. On the brick pushing rack, a first brick pushing plate and a second brick pushing plate are arranged in the brick incoming direction, and a third brick pushing plate is arranged between the first brick pushing plate and the second brick pushing plate. When the lifting roller row rises, it is at the same height as the first brick conveying rack or the second brick conveying rack, and when it falls, it is lower than the height of the conveyor belt or conveyor chain on the first brick receiving and conveying rack or the second brick receiving and conveying rack.

[0021] The brick discharging and packing method of the brick discharging and packing production line of the present application includes the following steps:

[0022] 1) The brick stack conveying rack conveys the brick stack to the stacking mechanism. The jacket parts of the stacking gripper plates of each layer of the stacking mechanism are vertically corresponding to form a stacking jacket, and are sleeved outside the brick stack, so that the jacket part of each layer of stacking gripper plate corresponds to each layer of brick layer of the brick stack;

[0023] 2) The first clamping mechanisms of each layer of stacking gripper plate first close and clamp to clamp and align the two ends of the bricks of the corresponding brick layer and hold them stably;

[0024] 3) From top to bottom, the first clamping mechanism of the topmost layer of brick piling chucks is loosened first, and the second clamping mechanism of the topmost layer of brick piling chucks closes and clamps, gathering the bricks in the topmost brick layer, eliminating the gaps between the bricks and clamping them; the topmost layer of brick piling chucks rotates by a certain angle. At the same time, the first clamping mechanism of the second layer of brick piling chucks is loosened, the second clamping mechanism closes and clamps, and rotates by a certain angle, successively separating each brick layer and rotating by a certain angle, so as to separate the brick layers with different orientations on the brick stack to both sides of the brick piling mechanism;

[0025] 4) The brick layers clamped on the brick piling chucks on both sides of the brick piling mechanism are respectively transferred to the first brick receiving conveyor and the second brick receiving conveyor, and are respectively transferred to the first brick feeding rack and the second brick feeding rack, and are conveyed by the first brick feeding rack and the second brick feeding rack to the brick stacking manipulator, where they are re-stacked by the brick stacking manipulator and enter the packaging process.

[0026] Preferably, in step 3), after the second clamping mechanism clamps the corresponding brick layer, the first clamping mechanism of this layer closes and clamps again; improving the clamping effect on the brick layer.

[0027] More preferably, in step 3), after each layer of brick piling chucks clamps the corresponding brick layer, it is lifted by a certain height to keep a certain gap between each brick layer.

[0028] In step 4), when the first brick receiving conveyor and the second brick receiving conveyor discharge bricks, after the first brick pushing plate contacts the bricks, the lifting roller row rises by a certain height, the second brick pushing plate advances a certain distance in the direction of the first brick pushing plate, the first brick pushing plate retreats while the second brick pushing plate pushes, and then both the first brick pushing plate and the second brick pushing plate retreat by a certain distance, and the third brick pushing plate pushes the bricks lifted by the lifting roller row onto the corresponding first brick feeding rack and second brick feeding rack.

[0029] The brick discharging and packing production line of the present application is reasonably designed. Through the brick piling mechanism, the whole stack is formed, the stack is stabilized, the gaps between the bricks are eliminated, clamped and separated, the brick layers with different orientations are separated, and are conveyed and gathered at the brick stacking manipulator by different conveying mechanisms for re-stacking and packing. Its brick piling and unloading efficiency is high, and the brick piling of one stack can be completed in 3 - 5 seconds. It is not only fast and has good effects, but also effectively solves the problem of brick adhesion that has always troubled the industry development through whole bricks, stack supporting and jacking separation gaps. Moreover, the brick pushing mechanism enables the bricks to be transferred smoothly, and has good use effects, with remarkable progress and worthy of wide promotion and application.

[0042] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0043] Embodiment 1

[0044] Refer to Figures 2 - 4, a brick discharging and packing production line, comprising a brick stack conveying rack 9, a stack splitting mechanism 2, a first brick receiving conveying rack 3, a second brick receiving conveying rack 4, a first brick delivering rack 5, a second brick delivering rack 6, a brick stacking manipulator 7 and a packaging section 8. The brick stack conveying rack 9 conveys the brick stack 1 to the position below the stack splitting mechanism 2. The stack splitting mechanism 2 includes columns 2-2 and multiple layers of stack splitting chucks 2-3 arranged on the columns 2-2. Each layer of stack splitting chucks 2-3 is rotatably connected to the columns 2-2. The stack splitting chuck 2-3 includes a jacket part 2-31. The jacket part 2-31 of each layer of stack splitting chucks 2-3 is provided with a first clamping mechanism 2-311 corresponding to the length direction of both ends of the brick and a second clamping mechanism 2-312 corresponding to the thickness direction of both side surfaces of the brick. The jacket parts 2-31 of each layer of stack splitting chucks 2-3 are vertically corresponding to form a stack splitting jacket.

[0045] See Figure 5 and 6 , the stack splitting chuck 2-3 includes a frame body. One end of the frame body is provided with an adjusting counterweight. One end of the frame body has a jacket part 2-31, and the other end opposite to the jacket part 2-31 is provided with an adjusting counterweight 2-32. The adjusting counterweight 2-32 is driven by an adjusting air cylinder to displace along the length direction of the frame body, so that the stack splitting chuck 2-3 maintains horizontal balance. A rotary fixing seat 2-33 is arranged in the middle of the frame body. The frame body is rotatably connected to the columns 2-2 through the rotary fixing seat 2-33. The rotary fixing seat 2-33 includes a rotary sleeve seat and a gear seat 2-331 that is sleeved on the column and cannot rotate. A driving gear 2-34 driven by a stepping motor 2-35 is arranged on the frame body. The driving gear 2-34 meshes with the gear seat 2-331. The gear seat 2-331 is a sector gear seat, which can reduce space occupation. A circular gear or gear ring can also be used. By the driving gear 2-34 walking on the gear seat 2-334, the rotary motion of the stack splitting chuck 2-3 is driven, and the rotation angle is made more accurate through the stepping motor 2-35. In this embodiment, the stack splitting chuck 2-3 rotates 90 degrees as an example for illustration.

[0046] Specifically, in this embodiment, a brick stack conveyor 9 is arranged in front of the stack splitting mechanism 2, and a first brick receiving conveyor 3 and a second brick receiving conveyor 4 are respectively arranged on both sides. The brick stack conveyor 9 can be a lifting conveyor. The brick stack 1 is conveyed by the brick stack conveyor 9 to the position to be stack split, which is located below the stack splitting jacket. Then, the brick stack conveyor 9 rises horizontally so that the brick stack 1 enters the stack splitting jacket from below the stack splitting jacket. In this embodiment, the brick stack conveyor 9 is a horizontal conveyor, the column 2-2 is a polygonal column, and a polygonal column sleeve 2-21 that can slide up and down is sleeved on the column 2-2. Each stack splitting chuck 2-3 is evenly distributed up and down on the polygonal column sleeve 2-21. A lifting adjustment counterweight 2-5 is arranged behind the stack splitting mechanism 2. The lifting adjustment counterweight 2-5 is connected to the top of the column sleeve 21 through a traction chain 2-51 that bypasses the sprocket at the top of the column 2-2. The traction chain 2-51 is driven by a stepping motor to adjust the lifting of the column sleeve 2-21 and the stack splitting chuck 2-3. During operation, first, the column sleeve 2-21 and the stack splitting chuck 2-3 are raised. Then, the brick stack conveyor 9 conveys the brick stack 1 to below the stack splitting chuck 2-3. The stack splitting chuck 2-3 descends and sleeves outside the brick stack 1, so that each brick layer of the brick stack 1 corresponds to each stack splitting chuck 2-3. Then, all the first clamping mechanisms 2-311 of each layer of the stack splitting jacket are closed and clamped to clamp and sort the two ends of the bricks in the brick layer, realizing stacking and supporting the stack. Then, the first clamping mechanism 2-311 of the topmost stack splitting chuck 2-3 is loosened, and the second clamping mechanism 2-312 is closed and clamped to gather the bricks in this brick layer, eliminate the gaps between the bricks and clamp them. Then, the first clamping mechanism 2-311 of this layer is closed and clamped again. The stepping motor 2-35 of this layer drives the corresponding driving gear 2-34 to rotate, so that the stack splitting chuck 2-3 of this layer rotates, clamps the topmost brick layer and rotates it to one side. Then, the first clamping mechanism 2-311 of the second-layer stack splitting chuck 2-3 is loosened, the second clamping mechanism 2-412 is closed and clamped, and the first clamping mechanism 2-311 is clamped again to clamp the second-layer brick layer and rotate it to the other side. From top to bottom, each layer of stack splitting chuck 2-3 clamps the bricks in the corresponding brick layer and rotates them to the left and right sides respectively, reaching the state as shown in Figure 3 to realize stack splitting. Both the first brick receiving conveyor 3 and the second brick receiving conveyor 4 are lifting brick receiving conveyors. The first brick receiving conveyor 3 and the second brick receiving conveyor 4 on both sides of the stack splitting mechanism 2 rise, successively receive the brick layers on the corresponding stack splitting chucks 2-3 and convey them forward, so that the brick layers are laid on the first brick receiving conveyor 3 and the second brick receiving conveyor 4. After the first brick receiving conveyor 3 and the second brick receiving conveyor 4 receive the bricks, each stack splitting chuck 2-3 rises and turns to the front side of the stack splitting mechanism 2 to perform stack splitting on the next stack of bricks. The first brick receiving conveyor 3 and the second brick receiving conveyor 4 both descend to the initial state after receiving the bricks, and respectively convey the bricks to the first brick conveyor 5 and the second brick conveyor 6. The first brick conveyor 5 and the second brick conveyor 6 then convey the bricks to the brick stacking manipulator 7, and re-stack them on the packaging section 8 for packaging.

[0047] As a further preferred solution, the rotary fixing base 2-33 further includes a jacking cylinder 2-332 disposed below it. The jacking cylinder 2-332 is connected to the column 2-2. After the stacking chuck 2-3 grabs a brick layer, it is jacked up by the jacking cylinder 2-332 to a certain height, creating a certain gap between the brick layers, facilitating the rotation of the stacking chuck 2-3 and avoiding accidents such as brick detachment caused by contact between the brick layers.

[0048] Embodiment 2

[0049] See Figures 7 - 11 , the difference between this embodiment and Embodiment 1 is that: in this embodiment, the stacking mechanism 2 uses two columns 2-2, and the stacking chucks 2-3 of each layer are arranged in a left-right cross pattern in sequence and are disposed on the column sleeves 2-21 through the rotary fixing bases 2-33. Each column sleeve 2-21 is connected with a lifting and adjusting mechanism. In this embodiment, the lifting and adjusting mechanism is two lifting and adjusting counterweights 2-5 provided for the corresponding two columns 2-2 on both sides of the stacking mechanism 2. The overall lifting and adjustment of the stacking chucks 2-3 on the two columns is realized through the lifting and adjusting counterweights 2-5 on both sides. The lifting and adjusting mechanism in this application can also be provided with a lifting and adjusting hydraulic cylinder or air cylinder above or below the column sleeve 2-21, and the lifting and adjustment of the column sleeve 2-21 is realized by pulling or jacking.

[0050] In this embodiment, the stacking chucks 2-3 are arranged in a left-right cross pattern in sequence on the column sleeves 2-21 of the two columns 2-2, so that the stacking chucks 2-3 with the same brick-grabbing direction are located on the same column 2-2. See Figure 9 , the first clamping mechanism 2-311 and the second clamping mechanism 2-312 of the stacking chucks 2-3 between the two side columns 2-2 are misaligned by 90 degrees. Two layers of bricks with perpendicular brick directions are distributed and grabbed onto two different columns 2-2, and then placed on the corresponding first brick-receiving conveyor 3 and second brick-receiving conveyor 4, reducing the load on a single column 2-2 and the lifting and adjusting counterweight 2-5.

[0051] At the brick output ends of the first brick receiving and conveying rack 3 and the second brick receiving and conveying rack 4, there are provided brick pushing mechanisms 10. The brick pushing mechanism 10 includes a lifting roller row 10-1 and a brick pushing frame 10-2 provided at the brick output end of the first brick receiving and conveying rack 3 or the second brick receiving and conveying rack 4. On the brick pushing frame 10-2, a first brick pushing plate 10-3 and a second brick pushing plate 10-4 are provided in the brick incoming direction, and a third brick pushing plate 10-5 is provided between the first brick pushing plate 10-3 and the second brick pushing plate 10-4. When the lifting roller row 10-1 rises, it is at the same height as the first brick conveying rack 5 or the second brick conveying rack 6. When it falls, it is lower than the height of the conveyor belt or conveyor chain on the first brick receiving and conveying rack 3 or the second brick receiving and conveying rack 4. The first brick pushing plate 10-3 and the second brick pushing plate 10-4 are both driven to translate by cylinders. The third brick pushing plate 10-5 can also be driven to translate by a cylinder, or as shown in the illustration of this embodiment, a walking beam connected by a rack and a slide rail is provided at the top of the brick pushing frame 10-2, and the third brick pushing plate 10-5 is provided at the bottom of the walking beam. The two ends are meshed with the rack through walking gears and are slidably connected to the brick pushing frame through the slide rail for position limiting and anti-disengagement. The walking gears are driven by a motor to walk on the rack, not shown in the figure, so as to realize pushing out the bricks through the third brick pushing plate 10-5. Refer to Figure 10 In [the figure], the third brick pushing plate 10-5 on the second brick receiving and conveying rack 4 is in the state after pushing out the bricks. After pushing out, it returns to the state of the brick pushing mechanism 10 on the first brick receiving and conveying rack 3.

At the same time, the first clamping mechanisms 2-311 of the second layer of stack separating clamping disc 2-3 loosen, the second clamping mechanisms 2-312 close and clamp, and rotate a certain angle. In turn, each brick layer is separated and rotated a certain angle, so as to realize separating the brick layers with different directions on the brick stack 1 to both sides of the stack separating mechanism 2;

[0059] Further as a preferred solution, in step 3), after each layer of splitting grippers 2-3 clamps the corresponding brick layer, before rotation, it is lifted to a certain height to keep a certain gap from the adjacent brick layer.

A brick discharging and packing method for the brick discharging and packing production line according to any one of claims 1-6, characterized in that: It includes the following steps: 1) The brick stack conveying rack conveys the brick stack to the stack splitting mechanism. The clamping sleeve parts of each layer of stack splitting chuck of the stack splitting mechanism are vertically corresponding to form a stack splitting clamping sleeve and are sleeved outside the brick stack, so that the clamping sleeve part of each layer of stack splitting chuck corresponds to each brick layer of the brick stack; 2) The first clamping mechanism of each layer of stack splitting chuck first closes and clamps to clamp and stack the bricks at the two ends of the corresponding brick layer and hold them steadily; 3) From top to bottom, the first clamping mechanism of the topmost layer of stack splitting chuck first loosens, and the second clamping mechanism of the topmost layer of stack splitting chuck closes and clamps to gather the bricks in the topmost brick layer, eliminate the gaps between the bricks and clamp them; the topmost layer of stack splitting chuck rotates a certain angle. At the same time, the first clamping mechanism of the second layer of stack splitting chuck loosens, the second clamping mechanism closes and clamps, and rotates a certain angle. In turn, each brick layer is separated and rotated a certain angle, so as to separate the brick layers with different directions on the brick stack to both sides of the stack splitting mechanism; 4) The brick layers clamped on the splitting chucks on both sides of the splitting mechanism are respectively transferred to the first brick receiving conveyor and the second brick receiving conveyor, and are respectively moved to the first brick conveying rack and the second brick conveying rack, and are conveyed to the brick stacking manipulator by the first brick conveying rack and the second brick conveying rack, and are re-stacked by the brick stacking manipulator and enter the packaging process.

8. The brick output and packing method according to claim 7, characterized in that: In step 3), after the second clamping mechanism clamps the corresponding brick layer, the first clamping mechanism of this layer closes and clamps again; after the splitting chucks of each layer clamp the corresponding brick layer, it is lifted to a certain height to keep a certain gap between each brick layer.

9. The brick discharging and packing method according to claim 8, characterized in that: In step 4), when the first brick receiving conveyor and the second brick receiving conveyor discharge bricks, after the first brick pushing plate contacts the bricks, the lifting roller row rises to a certain height, the second brick pushing plate advances a certain distance in the direction of the first brick pushing plate, the first brick pushing plate retreats while the second brick pushing plate is pushing, and then both the first brick pushing plate and the second brick pushing plate retreat a certain distance, and the third brick pushing plate pushes the bricks lifted by the lifting roller row onto the corresponding first brick conveying rack and the second brick conveying rack.
