Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic production, and particularly relates to a brick stacking method. BACKGROUND

[0002] The existing brick stacking device mainly has two ways. One is to stack bricks from top to bottom. This kind of device needs a set of ceramic tile suction and conveying mechanism to suck the ceramic tile from the conveying line and transport it to the stacking station for stacking. This kind of brick stacking device has a complex structure, and when the bricks are stacked, the transmission distance of the bricks is far, the transmission speed is low, and therefore the brick stacking efficiency is low. The other is to stack bricks from bottom to top. As disclosed in the patent CN201921304684.9, the ceramic tile enters the input end of the conveying device and is conveyed by the first conveying belt. After being centered by the first guide wheel of the centering mechanism, the ceramic tile is guided and conveyed to the baffle position of the positioning mechanism by the second guide wheels on both sides of the second conveying belt. After the induction switch senses the ceramic tile, the reduction drive device of the jacking mechanism drives the cam and link assembly at both ends to drive the guide column and the lifting plate. When the lifting plate rises, the ceramic tile on the second conveying belt is lifted. The second cylinder of the brick clamping mechanism drives the rotary arm of the clamping arm to rotate. The rotary arm drives the clamping arm to clamp the edge of the ceramic tile. The lifting plate is lowered. After the induction switch senses the ceramic tile, the lifting plate is lifted again to lift the ceramic tile on the second conveying belt. The induction switch controls the second cylinder of the brick clamping mechanism to drive the rotary arm of the clamping arm to rotate in the opposite direction. The rotary arm drives the clamping arm to release the clamped ceramic tile, so that the clamped ceramic tile is stacked with the ceramic tile lifted on the lifting plate. The second cylinder of the clamping arm drives the rotary arm to rotate in the forward direction, and the rotary arm drives the clamping arm to clamp the edges of the two stacked ceramic tiles. Although the patent claims to avoid violent collision with the ceramic tile, the brick stacking action is gentle, and it is especially suitable for large size ceramic tiles, but the brick stacking process needs to be completed by the jacking mechanism and the brick clamping mechanism in cooperation. That is, before the lower ceramic tile is lifted to the upper ceramic tile, the brick clamping mechanism must be opened, otherwise the lower ceramic tile will be lifted on the brick clamping mechanism and cannot be clamped by the brick clamping mechanism. When the jacking mechanism starts to fall, the brick clamping mechanism must clamp the ceramic tile, otherwise the ceramic tile will fall out of the action range of the brick clamping mechanism. This requires a very complex linkage control mechanism. Since the jacking mechanism uses a motor to drive a cam link, and the brick clamping mechanism uses a pneumatic device, if they are controlled separately, a sensing device needs to be set to sense the lifting position of the jacking mechanism. As determined by the patent technology, firstly, it is not easy to effectively set the sensing device, and secondly, even if the sensing device can be set, the sensing device is easy to be disturbed. If other linkage mechanisms are used, such as the patent CN201910739477.4 disclosed linkage mechanism, the mechanism is complex, and the ceramic tile production environment is often full of ceramic dust, and the complex mechanism is easy to be affected by the use environment; and the motor drives the cam connecting rod to drive, the equipment cost is high; in addition, the lifting ceramic tile upwards to superimpose with the previous ceramic tile in the above-mentioned patent technology process, since the lifting force upwards is an impact force with a certain speed, the ceramic tile still collides with the ceramic tile falling downwards, even if the lifting mechanism and the clamping mechanism cooperate to shorten the distance of the ceramic tile falling downwards to slow down the impact force of the ceramic tile falling, but since the lifting force of the lifting mechanism upwards is a hard force, the size of the hard force is related to the lifting speed, the hard force is low when the lifting speed is low, but the superimposed tile speed is slow, the lifting speed is high, the superimposed tile speed is fast, but the hard force is large, which is easy to cause damage to the ceramic tile. SUMMARY

[0003] The purpose of the present application is to provide a simple structure, low equipment cost, fast superimposed tile speed, and no damage to the ceramic tile.

[0004] The superimposed tile method of the present application is realized by comprising a rack, a conveying device arranged on the rack, a position sensor, a lifting mechanism and a tile supporting mechanism, the tile supporting mechanism comprising a cylinder arranged symmetrically on both sides of the conveying device, a clamping plate driven by the cylinder to move horizontally and linearly back and forth, the bottom of the clamping plate being provided with a supporting plate floating outward, the lifting mechanism comprising a lifting cylinder arranged in the lower part of the tile supporting mechanism, a lifting horizontal bracket driven by the lifting cylinder to move up and down linearly back and forth, the position sensor being located at the front end of the lifting mechanism, when superimposing tiles, the lifting mechanism is in the starting position, the ceramic tile reaches the position sensor under the conveying device, after the position sensor senses that the ceramic tile is in place, the conveying device is stopped by the control device, at the same time, the clamping plate on both sides of the tile supporting mechanism is driven by the cylinder to move to the outside away from the conveying device, at this time, if there is a ceramic tile on the tile supporting mechanism, the ceramic tile will fall on the ceramic tile on the conveying device, if the number of superimposed ceramic tiles has not reached the set number, the lifting horizontal bracket of the lifting mechanism is lifted to the tile supporting mechanism by the lifting cylinder of the lifting mechanism through the control device, so that the ceramic tile is in the action range of the tile supporting mechanism, the clamping plate on both sides of the tile supporting mechanism is driven by the cylinder to move to the inside in the direction of the conveying device through the control device, and the ceramic tile is clamped; if the number of superimposed ceramic tiles reaches the set number, the ceramic tile pile is sent away by the conveying device through the control device.

[0005] The technical solution of the patent application does not need positioning mechanism, and the bottom of the clamping plate of the tile supporting mechanism can be close to the tiles conveyed on the conveying device without the interference of the positioning mechanism, so as to effectively reduce the impact of the tiles falling from the tile supporting mechanism on the tiles conveyed on the conveying device, thereby avoiding the damage to the tiles when stacking, and the tiles will not be interfered by the positioning mechanism when falling, and the tiles are lifted to the tile supporting mechanism by the lifting mechanism after stacking, so that even if the lifting mechanism is quickly lifted, it will not cause impact damage to the tiles, thereby ensuring the speed and efficiency of tile stacking. Although the positioning of the positioning mechanism during tile stacking may cause slight misalignment of the tiles in the front and rear directions, the tiles need to be positioned during packaging, so it will not affect the smooth completion of the tile stacking and subsequent packaging process. The power of the lifting mechanism and the power of the tile supporting mechanism are both provided by the air cylinder, and the power transmission distance is short, so the tile stacking speed is fast, and the control device can be used to control the lifting mechanism and the tile supporting mechanism to work in sequence, which is simple and reliable. No complex linkage mechanism is needed to realize the linkage of the two, so the equipment cost is low.

[0006] Preferably, the position sensor comprises a swing lever arranged on the frame and a proximity switch, the switch sensing surface of the proximity switch is horizontally oriented and located below the conveying surface of the conveying device, and a spring is arranged between the swing lever and the frame. Under the action of the spring, one end of the swing lever is always located above the conveying surface of the conveying device, and the other end of the swing lever is located below the sensing surface of the proximity switch. When the tiles move to one end of the swing lever on the conveying device, the gravity of the tiles will press one end of the swing lever below the conveying surface of the conveying device, causing the other end of the swing lever to be raised to the switch sensing surface of the proximity switch, and the proximity switch will send a control signal to the control device, so that the control device controls the conveying device, the lifting mechanism and the tile supporting mechanism to work in sequence.

[0007] The tile stacking process of the patent application determines that if a proximity switch is used to directly sense whether the tiles are in place, there are only two ways: either a proximity switch is arranged on the side of the tiles or a proximity switch is arranged below the tiles. When the proximity switch is arranged on the side of the tiles, the tiles are relatively thin, and the tiles are placed on the conveying belt of the conveying device, so the proximity switch will be disturbed by the conveying belt and be mistakenly touched, or it cannot sense the arrival of the tiles. When the proximity switch is arranged below the tiles, the tiles supported by the tile supporting mechanism are very close to the tiles conveyed on the conveying belt, so they are easily disturbed by the tiles supported by the tile supporting mechanism and are mistakenly touched. The position sensor of the patent application uses the swing lever to convert, so the switch sensing surface of the proximity switch does not need to face the tiles, thereby avoiding the disturbance of the conveying belt or the tiles supported by the tile supporting mechanism, and ensuring the reliability of sensing the position of the tiles.

[0008] Preferably, a roller is rotatably arranged on one end of the swing lever. By using the roller, damage to the tiles is avoided when one end of the swing lever moves relative to the tiles.

[0009] Preferably, the tile stacking unit, which comprises a conveying device, a position sensor, a lifting mechanism and a tile supporting mechanism arranged on the frame, has two or more sets arranged in front and back, and the tiles are grouped into tile groups in a number matching the number of the tile stacking units, and the tile groups are sequentially fed into the tile stacking units for stacking. After the tiles in the tile groups in the set number are stacked in the tile stacking units, the tile groups are sequentially and simultaneously conveyed to the next process.

[0010] Since the time required for the next tile stack processing process is sometimes longer than the time for stacking a single tile stack, and the tile feeding in the previous process is continuous and cannot be stopped, multiple simultaneous processing processes need to be provided to match the stacking process to ensure smooth operation of the production line. Multiple tile stacking devices are used to almost simultaneously stack tiles, which prolongs the tile stacking time. After the tile groups completed almost simultaneously enter the next tile stack processing process, the next process can be processed almost simultaneously. Moreover, due to the prolonged tile stacking time, there is enough time for the next process to complete its processing work.

[0011] Compared with the prior art, the present application has the advantages of simple structure, low equipment cost, fast tile stacking speed, and no damage to the tiles. BRIEF DESCRIPTION OF DRAWINGS

[0017] The present application will be further described in detail in conjunction with the drawings and examples:

[0018] As Figure 1 , 2As shown in Figure 4, the brick stacking method of the present invention is implemented as follows: It includes a frame 1, a conveying device 2 mounted on the frame 1, a position sensor 3, a lifting mechanism 4, and a brick-supporting mechanism 5. The conveying device 2 is a belt-driven conveyor 2 powered by an electric device. The brick-supporting mechanism 5 includes two pairs of cylinders 501 symmetrically arranged on the left and right sides of the conveying device 2, and clamping plates 502 driven by the cylinders 501 to move horizontally back and forth. Each pair of cylinders 501 is positioned front and rear on the frame 1. A support plate 503 extending outwards is provided at the bottom of the clamping plate 502 to support the tile A and prevent the tile A from slipping off the clamping plate 502. The lifting mechanism 4 includes a lifting cylinder 401 located in the lower part of the brick-supporting mechanism 5, and a lifting horizontal support 402 driven by the lifting cylinder 401 to move vertically back and forth. The position sensor 3 is located at the front end of the lifting mechanism. When stacking bricks, the lifting mechanism 4 is in the initial position. After the tile A is aligned by the left and right alignment device 6, it is then... The tile A enters the conveying device 2 and is conveyed by the conveying device 2 to the position sensor 3. After the position sensor 3 senses that the tile A has arrived, it controls the conveying device 2 to stop conveying. At the same time, it controls the cylinders 501 on both sides of the tile-supporting mechanism 5 to move the clamping plate 502 away from the conveying device 2. At this time, if there is tile A on the tile-supporting mechanism 5, tile A will fall onto the tile A on the conveying device 2. If the number of stacked tiles A has not yet reached the set number, the control device controls the lifting cylinder 401 of the lifting mechanism 4 to lift the horizontal support 402 to the tile-supporting mechanism 5, so that tile A is within the range of action of the tile-supporting mechanism 5. The control device controls the cylinders 501 on both sides of the tile-supporting mechanism 5 to move the clamping plate 502 inward towards the conveying device 2 to clamp the tile A. If the number of stacked tiles A reaches the set number, the control device controls the start of the conveying device 2 to send the tile stack away.

[0019] like Figure 3 As shown, preferably, the position sensor 3 includes a swing arm 301 rotatably mounted on the frame 1 and a proximity switch 302. The switching sensing surface of the proximity switch 302 is oriented horizontally in the same direction as the conveying direction of the conveying device 2 and is located below the transmission surface of the conveying device 2. A spring (which may be a torsion spring sleeved on the shaft of the swing arm 301, not shown in the figure) is provided between the swing arm 301 and the frame 1. Under the action of the spring and the stop located below the other end of the swing arm 301, one end of the swing arm 301 is usually located above the transmission surface of the conveying device 2, and the other end of the swing arm 301 is located below the switching sensing surface of the proximity switch 302.

[0020] Preferably, a roller 303 is rotatably mounted on one end of the rocker arm 301.

[0021] like Figure 1As shown, the tile stacking units B, including the conveying device 2, the position sensor 3, the jacking mechanism 4 and the tile supporting mechanism 5 arranged on the rack 1, are more than two sets, and are arranged in front and back. The tiles A are grouped into tile groups in a number matching the number of the tile stacking units B, and are sequentially fed into each set of the tile stacking units B for stacking. After the tiles A in the tile groups in the set number are stacked in each set of the tile stacking units B, they are sequentially and simultaneously conveyed to the next process.

[0022] As Figure 5As shown, the tile stacking units B, including the conveying device 2, the position sensor 3, the jacking mechanism 4 and the tile supporting mechanism 5 arranged on the rack 1, have two sets. When starting to stack three tiles, the jacking mechanism 4 is in the initial position, the two tiles A of the first group are sequentially aligned by the left-right alignment device 6, and then enter the two sets of tile stacking units B, and are conveyed by the conveying device 2 to the position sensor 3 of the two sets of tile stacking units B. After the position sensor 3 senses that the tiles A are in place, the conveying device 2 is stopped by the control device, at the same time, the control device controls the air cylinders 501 on both sides of the tile supporting mechanism 5 to drive the clamping plates 502 to move away from the outside of the conveying device 2, then the control device controls the jacking air cylinder 401 of the jacking mechanism 4 to drive the jacking horizontal bracket 402 to rise to the tile supporting mechanism 5, so that the tiles A are in the action range of the tile supporting mechanism 5, at the same time, the control device controls the conveying device 2 to restart, and controls the air cylinders 501 on both sides of the tile supporting mechanism 5 to drive the clamping plates 502 to move to the inside in the direction of the conveying device 2, the tile supporting mechanisms 5 of the two sets of tile stacking units B clamp the two tiles A of the first group respectively, and the jacking mechanism 4 is reset. In this process, the two tiles A of the second group continuously enter the two sets of tile stacking units B, and pass through or enter the action range of the jacking mechanism 4 after the jacking mechanism 4 is reset. After the position sensor 3 senses that the tiles A of the second group are in place, the conveying device 2 is stopped by the control device, at the same time, the control device controls the air cylinders 501 on both sides of the tile supporting mechanism 5 to drive the clamping plates 502 to move away from the outside of the conveying device 2, so that the clamped tiles A fall onto the second group of tiles A on the conveying device 2, then the control device controls the jacking air cylinder 401 of the jacking mechanism 4 to drive the jacking horizontal bracket 402 to rise to the tile supporting mechanism 5, so that the tiles A are in the action range of the tile supporting mechanism 5, the control device controls the conveying device 2 to restart, and controls the air cylinders 501 on both sides of the tile supporting mechanism 5 to drive the clamping plates 502 to move to the inside in the direction of the conveying device 2, the tile supporting mechanisms 5 of the two sets of tile stacking units B clamp the two tiles A of the first group and the second group stacked together respectively, and the jacking mechanism 4 is reset. In this process, the two tiles A of the third group continuously enter the two sets of tile stacking units B, and pass through or enter the action range of the jacking mechanism 4 after the jacking mechanism 4 is reset. After the position sensor 3 senses that the tiles A of the third group are in place, the conveying device 2 is stopped by the control device, at the same time, the control device controls the air cylinders 501 on both sides of the tile supporting mechanism 5 to drive the clamping plates 502 to move away from the outside of the conveying device 2, so that the clamped two tiles A stacked together fall onto the third group of tiles A on the conveying device 2, the control device controls the conveying device 2 to restart, and the three tiles stacked together are conveyed out.
