Description

Technical Field

[0001] The invention relates to the technical field of brick production equipment, and in particular to a shale brick stacking mechanism. Background Art

[0002] When existing brick factories produce shale bricks, they stack the bricks into piles and burn them in brick kilns. The brick pile structure is as follows: Figure 1 As shown, in each layer of the brick stack, the bricks are adjacent to each other in the length direction and are spaced a certain distance apart in the thickness direction. The directions of the bricks in two adjacent layers are perpendicular to each other, so that gaps are formed between the bricks of the brick stack, which makes it easier for each brick in the brick stack to be well heated and ensures the sintering quality of the bricks.

[0003] After the bricks are sintered, they are unloaded from the kiln and packed. They need to be reorganized and stacked. The traditional method is done manually, which not only has a harsh working environment and high temperature, but also has high labor intensity, low efficiency and high labor costs. In recent years, some mechanized stacking and brick unloading equipment have also appeared. Although they can realize mechanized stacking and brick unloading, the effect is not ideal. During the sintering process of sintered bricks, the bricks will stick together. The existing mechanical stacking and brick unloading method breaks the bonding state between the single-layer bricks and the lower bricks through the cooperation of the upper and lower clamps. Usually, the lower bricks are clamped and the upper bricks are pushed horizontally. This method will cause the upper bricks to be separated from the lower bricks. Due to adhesion, the friction resistance increases, causing defects or bonding problems after the upper bricks are separated from the lower bricks, resulting in unsightly surface quality of the shale bricks after stacking, affecting their use.

DETAILED DESCRIPTION

[0042] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figure 1 As shown, combined Figure 2-4 The embodiment of the present invention discloses a shale brick stacking mechanism, which is used to stack and unload bricks after leaving the kiln, so as to facilitate subsequent equipment to stack and pack the bricks, so that the brick stacks are neatly arranged.

[0044] Specifically, the shale brick stacking mechanism disclosed in this embodiment includes a frame 1 and a brick separating mechanism 3 .

[0045] Among them, the frame 1 is used as the main body for installing the brick separation mechanism 3. It is a frame composed of four columns. The frame 1 can be connected to the crane for transferring brick stacks, and the frame 1 can also be connected to the subsequent palletizing and packaging equipment. A bearing platform 2 for placing brick stacks is arranged inside the frame 1. The number of bearing platforms 2 can be one or more, which is determined by the number of brick separation mechanisms 3. In the actual operation process, a group of vertically stacked brick stacks are transferred to the bearing platform 2 by the crane.

[0046] The brick separation mechanism 3 is arranged on the frame 1 above the carrying platform 2 and is used for separating the upper bricks from the lower bricks of the brick stack on the carrying platform 2 .

[0047] Specifically, the brick separating mechanism 3 includes a fixed frame 30 , a brick supporting assembly and a closing assembly 32 .

[0048] The fixed frame 30 is horizontally arranged on the frame 1, and the area of ​​the inner circle of the fixed frame 30 is larger than the area of ​​the brick pile, so that the fixed frame 30 can be mounted on the brick pile. The fixed frame 30 can move along the vertical direction of the frame 1 relative to the bearing platform 2 or the bearing platform 2 can move relative to the fixed frame 30. Specifically, as an embodiment, the bearing platform 2 is stationary, and the fixed frame 30 moves up and down along the frame 1, thereby adjusting the height of the fixed frame 30 mounted on the brick pile. As another embodiment, the fixed frame 30 is stationary, and the bearing platform 2 moves up and down along the frame 1, thereby adjusting the height of the brick pile on the bearing platform 2 extending into the fixed frame 30.

[0049] The brick supporting assembly 31 is arranged on the fixed frame 30, and is used to stabilize and fix the lower bricks on the brick stack, ensuring that the lower bricks remain stationary, so as to facilitate the closing assembly 32 to close the upper bricks, thereby separating the upper bricks from the lower bricks. The brick supporting assembly 31 includes a first clamping device 310 and a second clamping device 311 arranged on the fixed frame 30. The first clamping device 310 and the second clamping device 311 cooperate with each other to clamp the lower bricks on the top of the brick stack. Specifically, when the end face of the brick in the lower brick layer faces the first clamping device 310, and the side face of the brick faces the second clamping device 311, the first clamping device 310 is actuated to clamp the two end faces of the brick at the same time, so as to eliminate the gap between the end faces of the brick, thereby clamping the bricks to each other in the length direction. The second clamping device 311 may not move or may move slightly, only supporting the outermost brick side of the lower brick layer without translation and squeezing, so as to prevent the upper brick layer from falling down due to lack of support from the lower brick layer after the bricks are closed.

[0050] It is worth noting that the first clamping device 310 and the second clamping device 311 perform corresponding actions according to the stacking type of the lower layer of bricks.

[0051] The closing assembly 32 is arranged on the fixed frame 30 and is located directly above the brick supporting assembly 31, and is used for closing the upper bricks in a whole stack. The closing assembly 32 includes a first horizontal pushing device 321 and a second horizontal pushing device 322. The first horizontal pushing device 321 is located directly above the first clamping device 310, and the second horizontal pushing device 322 is located directly above the second clamping device 311. The first horizontal pushing device 321 and the second horizontal pushing device 322 cooperate with each other to close the upper bricks on the top of the brick stack; the first horizontal pushing device 321 includes a first push plate 3211 arranged on the inner side of a group of opposite sides of the fixed frame 30 and a first horizontal pushing cylinder 3212 on the outer side for driving the first push plate 3211 to move in translation; the second horizontal pushing device 322 includes a second push plate 3221 arranged on the inner side of another group of opposite sides of the fixed frame 30 and a second horizontal pushing cylinder 3222 on the outer side for driving the second push plate 3221 to move in translation; the opposite sides of the two groups of first push plates 3211 and second push plates 3221 are inclined.

[0052] According to the arrangement, after the lower bricks are stabilized and fixed by the brick supporting assembly 31, the first horizontal push cylinder 3212 drives the first push plate 3211 to move horizontally, and the second horizontal push cylinder 3222 drives the second push plate 3221 to move horizontally. Since the first push plate 3211 and the second push plate 3221 have an inclined surface opposite to each other, the upper part of the first push plate 3211 and the second push plate 3221 first contact the upper part of the bricks. When pushing the bricks, the upper bricks and the lower bricks can be easily separated by lever principle, avoiding the upper bricks and the lower bricks from being separated by horizontal friction shear, causing defects or bonding problems between bricks, and improving the surface quality of the shale bricks after stacking. During the continuous translation of the first push plate 3211 and the second push plate 3221, the upper bricks can be closed inward for shaping.

[0053] It is worth noting that when the first clamping device 310 cooperates with the brick end face of the lower layer to clamp and stabilize, the first push plate 3211 cooperates to push the brick side face of the upper layer, and the second push plate 3221 cooperates to push the brick end face of the upper layer. When the second clamping device 311 cooperates with the brick end face of the lower layer to clamp and stabilize, the first push plate 3211 cooperates to push the brick end face of the upper layer, and the second push plate 3221 cooperates to push the brick side face of the upper layer. The above implementation is determined according to the placement of the brick stack on the carrying platform 2 after leaving the kiln.

[0054] Since the brick separating mechanism 3 separates the two layers of bricks on the brick stack from top to bottom, it is necessary to adjust the relative height between the fixed frame 30 and the carrying platform 2.

[0055] As an embodiment, the bearing platform 2 is fixedly arranged at the bottom of the frame 1, a first slide rail 11 is vertically fixedly arranged on the frame 1, and the fixed frame 30 is slidably arranged on the first slide rail 11 and can move up and down along the first slide rail 11. In this configuration, the bearing platform 2 is fixed at the bottom of the frame 1, and the height between the fixed frame 30 and the bearing platform 2 in the vertical direction is adjusted by moving the fixed frame 30 up and down, so that the brick separation mechanism 3 can perform brick separation operation from top to bottom in two layers.

[0056] As another embodiment, the fixed frame 30 is horizontally fixed on the top of the frame 1, a first slide rail 11 is vertically fixed on the frame 1, and the bearing platform 2 is slidably disposed on the first slide rail 11 and can move up and down along the first slide rail 11. In this configuration, the fixed frame 30 is fixed on the top of the frame 1, and the height between the fixed frame 30 and the bearing platform 2 in the vertical direction is adjusted by moving the bearing platform 2 up and down, so that the brick separation mechanism 3 performs brick separation operation from top to bottom in two layers.

[0057] In the above two embodiments, the fixed frame 30 and the carrying platform 2 can be driven by a sprocket chain or a gear 427 rack, both of which are commonly used driving methods in the prior art.

[0058] In order to enable the brick supporting assembly 31 to stabilize and fix the lower bricks, the solution adopted in this embodiment is: the first clamping device includes a first clamping plate 3101 and a first clamping cylinder 3102, and the second clamping device 311311 includes a second clamping plate 3111 and a second clamping cylinder 3112. The first clamping plate 3101 is arranged on the inner side of a group of opposite sides of the fixed frame 30 and is located directly below the first push plate 3211; the first clamping cylinder 3102 is arranged on the outer side of the fixed frame 30 and is used to drive the first clamping plate 3101 to translate; the second clamping plate 3111 is arranged on the inner side of another group of opposite sides of the fixed frame 30 and is located directly below the second push plate 3221; the second clamping cylinder 3112 is arranged on the outer side of the fixed frame 30 and is used to drive the second clamping plate 3111 to translate.

[0059] Thus, when the brick separating mechanism 3 is implementing the operation of separating and stacking the brick stacks on the supporting platform 2, the fixed frame 30 moves downward along the frame 1 so that the fixed frame 30 is sleeved on the top of the brick stack, and the two groups of first clamping plates 3101 and the two groups of second clamping plates 3111 enclose the lower bricks. When the end faces of the bricks of the lower bricks face the first clamping plates 3101, the side faces of the bricks of the lower bricks face the second clamping plates 3111. At this time, the first clamping cylinder 3102 drives the first clamping plates 3101 to translate, and the two groups of first clamping plates 3101 translate relative to each other, and at the same time clamp the two end faces of the bricks to eliminate the gap between the end faces of the bricks, thereby realizing the bricks being clamped to each other in the length direction. At this time, the second clamping plate 3111 is slightly translated under the drive of the second clamping cylinder 3112, and only supports the outermost brick side of the lower brick, without performing translation and extrusion, to prevent the upper brick from falling due to lack of support from the lower brick after the bricks are closed. According to the different initial brick stack placement forms, the end face of the lower brick will also face the second clamping plate 3111, and the corresponding side face of the lower brick will face the first clamping plate 3101.

[0060] On the basis of the above embodiment, after the lower bricks are stabilized and clamped by the first clamping plate 3101 and the second clamping plate 3111, the lower bricks remain stationary on the horizontal plane. At this time, the first push plate 3211 corresponds to the side of the bricks of the upper bricks, and the second push plate corresponds to the end of the bricks of the upper bricks. The first push cylinder 3212 drives the first push plate 3211 to move horizontally, and the second push cylinder 3222 drives the second push plate 3221 to move horizontally. Since the first push plate 3211 and the second push plate 3221 are relatively One side is set in an inclined shape, and the upper part of the first push plate 3211 and the second push plate 3221 first contacts the upper part of the brick, that is, the first push plate 3211 contacts the upper part of the side of the brick, and the second push plate 3221 contacts the upper part of the end surface of the brick. When pushing the brick, the upper brick and the lower brick can be easily separated by lever principle, avoiding the upper brick and the lower brick to be separated by horizontal friction shear, causing defects or bonding problems between bricks, and improving the surface quality of shale bricks after stacking. During the relative translation of the two groups of first push plates 3211 and the relative translation of the two groups of second push plates 3221, the upper bricks can be closed inward for shaping.

[0061] In order to make the first push plate 3211 and the second push plate 3221 separate the upper bricks and the lower bricks well during the translation process, and prevent the bricks from falling, the scheme adopted in this embodiment is: the distance from the top surface of the first push plate 3211 to the inner side surface of the fixed frame 30 is greater than the distance from the bottom surface of the first push plate 3211 to the inner side surface of the fixed frame 30; the distance from the top surface of the second push plate 3221 to the inner side surface of the fixed frame 30 is greater than the distance from the bottom surface of the second push plate 3221 to the inner side surface of the fixed frame 30; at the same time, the inclination angles of the first push plate 3211 and the second push plate 3221 are both 1° to 20°. With the above technical solution, the first push plate 3211 and the second push plate 3221 are inclined downward, and the angle is set in this way. When the upper bricks and the lower bricks are easily separated, the bricks can be prevented from falling, and the upper bricks can be smoothly stacked. Specifically, if the angle is too small, the contact area between the first push plate 3211 and the second push plate 3221 and the bricks is large, close to flat push, at this time the upper bricks and the lower bricks are in surface contact, separated by mutual friction and shearing, which will at least cause adhesion or surface defects of the separated bricks. If the angle is too large, the first push plate 3211 and the second push plate 3221 are likely to push the bricks when pushing the upper bricks, making them unable to close.

[0062] Since the brick supporting assembly 31 and the closing assembly 32 are arranged inside the fixed frame 30, they both adopt an enclosure method to achieve stabilization or closing of the brick layer. Each stacking mechanism can only perform stacking operations on one brick stack, which will result in low efficiency. If multiple stacking mechanisms are set in the plane direction, each stacking mechanism needs to be equipped with a fixed frame 30, which will cause the shale brick stacking and packaging equipment to be bulky and have a large space occupancy rate.

[0063] For this purpose, refer to the attached Figure 4 As shown, the solution adopted in this embodiment is that two groups of supporting brick components 31 and two groups of closing components 32 are arranged in the fixed square frame 30, wherein the two groups of supporting brick components 31 and the two groups of closing components 32 are respectively arranged horizontally side by side on the fixed square frame 30, and the closing components 32 are located directly above the supporting brick components 31. With this arrangement, the stacking operation of two groups of brick stacks can be carried out at the same time.

[0064] Specifically, in order to ensure that the two groups of supporting brick assemblies 31 and the two groups of closing assemblies 32 form an enclosed structure in the fixed frame 30, the solution adopted in this embodiment is: the first clamping plate 3101 is arranged side by side in the middle of the fixed frame 30 along the length direction of the fixed frame 30, and the other two first clamping plates 3101 are respectively arranged on the inner side walls of the fixed frame 30 in the length direction; the two first push plates 3211 are arranged side by side in the middle of the fixed frame 30 along the length direction of the fixed frame 30, and the other two first push plates 3211 are respectively arranged on the inner side walls of the fixed frame 30 in the length direction, and the first push plate 3211 is located directly above the first clamping plate 3101, and the first clamping cylinder and the first push cylinder 3212 are both arranged on the outer side walls at both ends of the length direction of the fixed frame 30, respectively connecting the first clamping plate 3101 and the first push plate.

[0065] Thus, the fixed frame 30 is set to a rectangular structure, and the two groups of stacking mechanisms are integrated together through the fixed frame 30 to form a brick separation mechanism 3. By arranging two groups of first clamping plates 3101 side by side in the middle of the fixed frame 30, and arranging two groups of first push plates side by side directly above the two groups of first clamping plates 3101, the first clamping plates 3101 and the first push plates are installed on both inner sides of the length direction of the fixed frame 30, and two groups of second clamping plates 3111 and two groups of second push plates are arranged on both inner sides of the width direction of the fixed frame 30. It can meet the requirements that two groups of brick supporting components 31 and two groups of closing components 32 can synchronously implement the stacking operation on two groups of brick piles in the same fixed frame 30. At the same time, the first clamping cylinder and the first push cylinder 3212 are set on the outer walls at both ends of the length direction of the fixed frame 30, which are respectively connected to the first clamping plate 3101 and the first push plate. The driving mechanism can be dispersed on both sides of the length direction of the fixed frame 30. In this way, the structure of the entire brick separating mechanism 3 is optimized, so that one stacking mechanism can implement the stacking operation of two groups of brick piles at the same time. At the same time, the structure is compact and does not occupy a large space.

[0066] Based on the above embodiment, both ends of the first clamping plate 3101 in the middle of the fixed frame 30 are connected to the piston rod of the first clamping cylinder 3102, and both ends of the first push plate are connected to the piston rod of the first push cylinder 3212. However, since the first clamping cylinder 3102 and the first push cylinder 3212 are located on the side wall in the length direction of the fixed frame 30, the piston rod is relatively long. During the driving translation process, the first clamping plate 3101 and the first push plate in the middle of the fixed frame 30 are prone to shaking and are unstable.

[0067] To this end, the technical solution adopted in this embodiment is: two second slide rails 301 parallel to each other are arranged on both inner side walls in the length direction of the fixed frame 30, and the first clamping plate 3101 and the first push plate in the middle of the fixed frame 30 are respectively slidably connected to the second slide rails 301. In this way, the first clamping plate 3101 and the first push plate can be guided by the second slide rails during the translation process, which plays a role in translation stability.

[0068] It is worth noting that in the above embodiment, the first clamping plate 3101, the second clamping plate 3111, the first push plate 3211 and the second push plate 3221 are all provided with guide rods (not shown in the figure) near the inner side of the fixed frame 30, so that the first clamping plate 3101, the second clamping plate 3111, the first push plate 3211 and the second push plate 3221 can be horizontally guided by the corresponding guide rods during translation, so that their movement is smooth.

[0069] After the upper bricks are closed and shaped, they need to be transferred and stacked. For this purpose, the technical solution adopted in this embodiment is: by setting a grasping mechanism 4, the specific grasping mechanism 4 can be connected to a stacking robot, and can also be connected to other stacking equipment to realize the stacking and packaging operations after grasping the upper bricks.

[0070] See attached Figure 5 As shown, the grabbing mechanism 4 of this embodiment includes a fixing plate 41 , a connecting rod assembly 42 , a grabbing cylinder 43 and a plurality of clips 44 .

[0071] There are two groups of multiple clips 44 symmetrically arranged on both sides of the fixing plate 41 , and the upper ends of the clips 44 are hingedly connected to the fixing plate 41 , so as to grasp the upper brick layer after closing.

[0072] One end of the grabbing cylinder 43 is fixedly connected to the inner side of the clip 44 on one side of the fixing plate 41, and the other end of the grabbing cylinder 43 is hinged to the inner side of the clip 44 on the other side of the fixing plate 41; the grabbing cylinder 43 can be used to open or close the symmetrical clips 44 on both sides of the fixing plate 41.

[0073] The connecting rod assembly 42 includes a first hinge rod 421, a second hinge rod 422, a third hinge rod 423 and a hinge seat 424. The hinge seat 424 is fixedly installed on the bottom surface of the fixed plate 41. The middle part of the third hinge rod 423 is materially connected to the hinge seat 424. The two ends of the third hinge rod 423 are respectively hinged to one end of the first hinge rod 421 and the second hinge rod 422. The other end of the first hinge rod 421 is hinged to the inner side of the clip 44 on one side of the fixed plate 41, and the other end of the second hinge rod 422 is hinged to the inner side of the clip 44 on the other side of the fixed plate 41. By means of this arrangement, one end of the second hinge rod 422 is hingedly connected to the inner wall of the one side clamp 44, and the other end of the second hinge rod 422 is hingedly connected to one end of the third hinge rod 423, the flipping angle of the one side clamp 44 can be constrained. At the same time, due to the travel restriction of the second hinge rod 422, when the piston rod of the grabbing cylinder 43 pushes the other side clamp 44 to open, the fixed end of the grabbing cylinder 43 can be provided with reaction by the clamp 44 on the side of the second hinge rod 422. At the same time, the first hinge rod 421 can limit the flipping angle of the one side clamp 44 by hingedly connecting the clamp 44 and the third hinge rod 423, thereby limiting the moving travel of the grabbing cylinder 43.

[0074] After the upper bricks are closed and grabbed, the lower bricks as the top layer are closed, and their closed shape is inconsistent with the upper bricks. They need to be rotated 90 degrees to facilitate the unification of the shape after subsequent stacking. For this reason, the solution adopted in this embodiment is: the grabbing mechanism 4 also includes a mounting plate 425, a rotating motor 426, a driving gear 427 and a toothed disc 428. The mounting plate 425 is arranged above the fixed plate 41, and is used to connect with the grabbing manipulator or transfer equipment. The toothed disc 428 is horizontally fixed on the fixed plate 41, and the rotating motor 426 is fixedly mounted on the mounting plate 425. The output shaft of the rotating motor 426 is meshed and connected with the toothed disc 428 through the driving gear 427. According to this arrangement, the gear 427 is driven to rotate by the rotating motor 426, and the toothed disc 428 is driven to rotate during the rotation of the gear 427. The toothed disc 428 and the fixed plate 41 are fixed as a whole, thereby driving the entire grabbing mechanism 4 to rotate a predetermined angle.

[0075] The working principle of the present invention is:

[0076] The brick pile to be stacked is transferred to the bearing platform 2 by the crane, and the fixed frame 30 moves downward along the frame 1 so that the fixed frame 30 is sleeved on the top of the brick pile. Two groups of first clamping plates 3101 and two groups of second clamping plates 3111 enclose the lower bricks. When the end face of the brick of the lower brick is facing the first clamping plate 3101, the side face of the brick of the lower brick is facing the second clamping plate 3111. At this time, the first clamping cylinder 3102 drives the first clamping plate 3101 to translate, and the two groups of first clamping plates 3101 translate relative to each other, and clamp the two end faces of the brick at the same time to eliminate the gap between the end faces of the brick, thereby achieving the bricks clamping each other in the length direction. At this time, the second clamping plate 3111 is slightly translated under the drive of the second clamping cylinder 3112, and only the outermost brick side of the lower brick is supported, without translation and extrusion. When the lower bricks are stabilized and clamped by the first clamping plate 3101 and the second clamping plate 3111, the lower bricks remain stationary on the horizontal plane. At this time, the first push plate corresponds to the side of the bricks of the upper bricks, and the second push plate corresponds to the end of the bricks of the upper bricks. The first push cylinder 3212 drives the first push plate 3211 to move horizontally, and the second push cylinder 3222 drives the second push plate 3221 to move horizontally. Since the opposite sides of the first push plate 3211 and the second push plate 3221 are arranged in an inclined shape, the upper parts of the first push plate 3211 and the second push plate 3221 first contact with the upper part of the bricks, that is, the first push plate 3211 contacts with the upper part of the side of the bricks, and the second push plate 3221 contacts with the upper part of the end of the bricks. When pushing the bricks, the lever principle can be used to easily separate the upper bricks and the lower bricks, thereby avoiding the upper bricks and the lower bricks from being separated by horizontal friction shear, causing defects or bonding problems between the bricks, and improving the surface quality of the shale bricks after stacking. During the relative translation of the two sets of first push plates 3211 and the two sets of second push plates 3221, the upper bricks can be closed inwards for shaping. After the upper bricks are closed, the grabbing mechanism 4 grabs the bricks and moves them to the stacking device for stacking and packaging. The stacking mechanism moves downward along the frame 1 to perform stacking of the next layer of bricks.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
