Description

Technical Field

[0001] The present invention relates to the technical field of tile transmission, and particularly to a translational elevator for tile transmission and its transmission method. Background Art

[0002] In the production process of the ceramic industry, lifting equipment is an important link connecting various processes, especially in the process of transporting tiles from the press workshop to multi-layer drying kilns. With the large-scale of ceramic tile specifications and the expansion of production scale, the requirements for lifting equipment are increasing day by day, especially the need to balance lifting efficiency and tile quality assurance.

[0003] Currently, there are mainly two types of elevators in the ceramic industry: one is the overall lifting elevator, which is characterized by a complex structure, a slow lifting speed, and a high positioning accuracy requirement; the other is the swing arm type lifting mechanism, which is widely used in scenarios such as glaze line climbing or plane height adjustment. For example, when producing 800*800 mm specification tiles, a swing arm type elevator is used to transport the tiles to a three-layer drying kiln.

[0004] These two types of lifting equipment play an important role in the existing ceramic production line, but each has obvious limitations. Due to the internal multi-layer platform structure of the overall lifting elevator, it is extremely difficult to clean when there are defective tiles, affecting production continuity; while the swing arm type lifting mechanism, although relatively simple in structure, its working principle determines that the swing arm needs to swing back and forth continuously. The action frequency of the swing is difficult to increase and the vibration generated when it stops swinging is significant. Especially when producing green body tiles, when the lifting speed is increased to improve production capacity, the vibration of the swing arm will cause internal cracks in the upper green body tiles, and in severe cases, they will even break in half after coming out of the drying kiln. In many production scenarios, this defect of the swing arm type elevator has become a bottleneck restricting the improvement of production capacity and cannot meet the modern requirements of high-efficiency and high-quality production of large-size tiles. Summary of the Invention

[0005] Aiming at the above defects, the purpose of the present invention is to propose a translational elevator for tile transmission and its transmission method, which solves the problems of the existing integral elevator with a complex structure, high use and maintenance costs, low transmission efficiency of the existing swing arm type elevator, and the inability to improve transmission efficiency and tile quality simultaneously.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A translational elevator for tile transmission, comprising a frame, a guide plate, an annular transmission component, and a plurality of moving components;

[0008] The vertical surface of the frame is provided with an annular track, and the annular transmission component is installed in the annular track, and the annular transmission component is used to drive a plurality of moving components to move cyclically along the annular track;

[0009] The guide plate is installed on the frame, and the guide plate is provided with a guide track; the guide track is located behind the annular track;

[0010] The moving assembly includes a fixed frame, a bracket, a first support portion, and at least three second support portions. One end of the first support portion is installed on the fixed frame and is connected to the bracket. The bracket is used to carry tiles or green bricks. The other end of the first support portion is installed through the annular transmission assembly. At least three second support portions are arranged at intervals along the circumference of the first support portion. One end of the second support portion is connected to the fixed frame, and the other end of the second support portion is inserted into the guide track. The first support portion moves under the drive of the annular transmission assembly, and the second support portion follows the movement of the first support portion and moves along the guide track.

[0011] Preferably, at least two first bearings are sleeved on one end of the first support portion. At least two first bearings are arranged at intervals along the length direction of the first support portion. A first chute matching the first bearings is arranged in the annular track. The first bearings are slidably arranged in the first chute. The middle part of the first support portion is inserted through the annular transmission assembly, and the other end of the first support portion is connected to the bracket.

[0012] Preferably, three second support portions are provided. The distances between the three second support portions and the first support portion are equal, and the three second support portions are evenly distributed around the first support portion at equal intervals;

[0013] The cross-section of the guide track is a C-shaped groove. The second support portion is sleeved with a second bearing and a third bearing. The outer diameter of the second bearing matches the opening width of the C-shaped groove. The second bearing is slidably arranged at the opening of the C-shaped groove. The outer diameter of the third bearing matches the inner width of the C-shaped groove. The third bearing is slidably arranged in the C-shaped groove.

[0014] Preferably, the annular transmission assembly includes a first servo motor, a chain, and at least four gears. The chain is arranged along the transmission direction of the annular track to form a closed-loop structure. The gears are arranged on the inner side of the ring of the chain. The gears are used to drive and support the chain to be tightened. The output part of the first servo motor is drivingly connected to at least one of the gears; the chain is arranged with two layers of chains in parallel, and the gears are double-layer gears corresponding to the chain.

[0015] Preferably, the chain includes a plurality of chain links and hollow pin shafts. The chain links are movably connected through the hollow pin shafts. The first support portion is inserted through the hollow pin shafts.

[0016] Preferably, it further includes two transmission platforms. The transmission platform includes a first inductor, a first driver, a first connecting frame, and a plurality of first rollers. The plurality of first rollers are horizontally arranged on one side of the first connecting frame. In the same transmission platform, the plurality of first rollers are arranged at intervals in the same plane. The bracket includes a connecting rod and a plurality of supporting rods. One end of the supporting rod is connected to one side in the width direction of the connecting rod. In the same bracket, the plurality of supporting rods are parallel to each other and arranged at intervals. The other side in the width direction of the connecting rod is connected to the first supporting portion. The first driver is used to drive the first rollers to rotate, and the first inductor is used to sense the position of the ceramic tile;

[0017] The interval between the plurality of first rollers of the transmission platform is used to clear the bracket, so that the bracket can pass through the transmission platform.

[0018] Preferably, the moving assembly includes a second inductor, a second driver, a second connecting frame, and a plurality of second rollers. The plurality of second rollers are horizontally arranged on the second connecting frame. In the same bracket, the plurality of second rollers are arranged in the same plane. The second driver is used to drive the second rollers to rotate, and the second inductor is used to sense the position of the ceramic tile on the bracket;

[0019] It further includes a third inductor. The third inductor is electrically connected to the annular transmission assembly. The third inductor is used to sense the position of the bracket.

[0020] Preferably, the length direction of the connecting rod or the second connecting frame is parallel to the incoming and outgoing directions of the ceramic tile. The length of the connecting rod or the second connecting frame is 800 millimeters, and the length of the supporting rod or the second roller is 1300 millimeters.

[0021] Preferably, the frame includes a first lifting frame and a second lifting frame. The two transmission platforms are respectively arranged on the first lifting frame and the second lifting frame in a liftable manner.

[0022] A method for lifting and transporting ceramic tiles uses the above-mentioned translational elevator. The moving speed of the moving assembly is controlled by the annular transmission assembly, running at 15 - 25 meters per minute for 1 - 5 seconds, then decelerating for 1 - 3 seconds to 0 - 10 meters per minute, maintaining at 0 - 10 meters per minute for 1 - 3 seconds, and then accelerating for 1 - 3 seconds to restore the running speed of 15 - 25 meters per second, and so on in a cycle. And the bracket is set to pass through the incoming and outgoing positions of the ceramic tile during the 1 - 3 - second interval of maintaining a running speed of 0 - 15 meters per minute.

[0023] The technical solution provided by the present invention may include the following beneficial effects:

[0024] 1. The first support part is limited perpendicular to the transmission direction by the annular track, and the second support part is limited perpendicular to the transmission direction by the guiding track, ensuring that the whole moving component translates along the transmission direction. Through the movement of the moving component along the annular track, the translation and lifting of the tiles carried thereon are realized. By increasing the number of simultaneously operating moving components, multiple moving components move cyclically along the transmission direction, enabling the large-scale continuous transmission of tiles, improving the transmission efficiency, without the need to pause the transfer of tiles or green bricks, and without equipment jitter caused by high-speed operation. This solves the problem that in the conventional reciprocating lifting equipment, increasing the reciprocating moving speed to improve the transmission efficiency will inevitably lead to an increase in equipment jitter, affecting the quality of tiles, and the transmission efficiency is difficult to further improve due to the limitation of inertial force.

[0025] 2. By fixing the guiding plate to the frame and setting the guiding plate vertically, when the tile is damaged, small pieces of broken tiles will fall to the ground at the bottom of the frame, facilitating cleaning, thus solving the problem of difficult cleaning of broken tiles inside the conventional elevator.

[0026] 3. The first support part is limited perpendicular to the transmission direction through the cooperation of the first bearing and the first sliding groove, realizing the limit of the moving component perpendicular to the transmission direction. By arranging the annular transmission component in the middle of the first support part, the first bearings and the brackets are respectively arranged at both ends, and the intervals between the first bearings are used, forming a multi-point support structure in the first support part, making the movement on one side of the bracket smoother and less likely to vibrate, solving the problem that the moving component shakes violently due to the chain shaking or encountering small foreign objects in the guiding plate during the movement of the moving component, affecting the quality of the supported tiles. The first support part is the main support structure of the moving component. By setting the connection between the first support part and the annular transmission component in the middle of the first support part and using multiple first bearings, the local stress of the first support part can be effectively reduced, increasing the overall service life of the moving component. By adding stabilizing sliders, the support points of the first support part are further increased, further enhancing the smoothness of the moving component.

[0027] 4. The overall support of the moving component is formed by the equilateral triangle structure formed by three second support parts, preventing the bracket from tilting. The triangular structure is not easily deformed and has good overall stability. Through the double-layer structure of the second bearing and the third bearing, the smoothness of the second support part sliding along the guiding track is increased, and the support stability is further enhanced in cooperation with the C-shaped groove of the guiding track, while preventing the second support part from accidentally falling off the second slide rail, solving the problems that the moving component cannot ensure balance and the track moving mode is prone to accidental derailment.

[0028] 5. By setting up a double-layer chain and precisely controlling it with the first servo motor, after the gears tighten the chain, when the chain drives the overall movement of the moving component, there will be no reciprocating swing along the transmission direction. It can stably drive the overall movement of the moving component along the transmission direction, and the transmission process is stable, solving the problem that conventional lifting mechanisms are prone to overall jitter during acceleration, deceleration, or high-speed operation, which affects the quality of the supported tiles.

[0029] 6. By arranging the first support part in the hollow pin shaft, the first support part will not affect the rotation between the chain links, and at the same time, it can ensure a large contact area to achieve stable transmission connection, avoiding the phenomenon that the restricted chain link jumps when moving to the turning point due to the restricted rotation between the chain links, resulting in the jitter of the moving component and affecting the quality of the supported tiles.

[0030] 7. By using a motor with a smaller power, the control accuracy of the transmission is higher, the stability is better, and at the same time, the use cost is lower and the operating noise is smaller.

[0031] 8. Both the bracket and the transmission platform adopt a single-sided support structure, enabling the moving component to achieve continuous transmission and increasing the transmission efficiency. The number of brackets running simultaneously on the guide plate is limited by the minimum distance between the brackets. By setting the connecting rod or the second connecting frame to the shorter side, interference between the brackets at the turning point can be avoided. By setting the shorter side parallel to the incoming and outgoing directions of the tiles, the incoming and outgoing distances of the tiles can be shortened, and the tile transfer time can be shortened at the same incoming and outgoing speeds. By reducing the distance between the brackets with the above structure, the number of brackets used simultaneously in the guide plate is increased, and the transmission efficiency is increased.

[0032] 9. By controlling the moving speed of the moving component and the acceleration during acceleration and deceleration, the bracket decelerates gently when lifting and lowering the tiles to handle them with care, ensuring that the force on the tiles during the overall transmission and lifting process does not exceed the process limit, and accelerating to the maximum operating speed during operation to improve the transportation efficiency.

[0046] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0047] A translational elevator for tile transfer includes a frame 1, a guide plate 2, an annular transfer assembly 3, and a plurality of moving assemblies 4;

[0048] An annular track 21 is provided on the vertical surface of the frame 1, and the annular transfer assembly 3 is installed in the annular track 21. The annular transfer assembly 3 is used to drive a plurality of moving assemblies 4 to move cyclically along the annular track 21;

[0049] The guide plate 2 is installed on the frame 1, and the guide plate 2 is provided with a guide track 22; the guide track 22 is located behind the annular track 21;

[0050] The moving assembly 4 includes a fixing frame 41, a bracket 42, a first support portion 43, and at least three second support portions 44. One end of the first support portion 43 is installed on the fixing frame 41 and is connected to the bracket 42. The bracket 42 is used to carry tiles or green bricks. The other end of the first support portion 43 is installed through the annular transfer assembly 3. At least three second support portions 44 are arranged at intervals along the circumference of the first support portion 43. One end of the second support portion 44 is connected to the fixing frame 41, and the other end of the second support portion 44 passes through the guide track 22. The first support portion 43 moves under the drive of the annular transfer assembly 3, and the second support portion 44 follows the movement of the first support portion 43 and moves along the guide track 22.

[0051] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the first support part 43 is limited perpendicular to the transmission direction by the annular track 21, and the second support part 44 is limited perpendicular to the transmission direction by the guiding track 22, ensuring that the whole moving component 4 translates along the transmission direction. Through the movement of the moving component 4 along the annular track 21, the translation and lifting of the tiles carried thereon are realized. By increasing the number of simultaneously operating moving components 4, multiple moving components 4 move cyclically along the transmission direction, enabling the large-scale continuous transmission of tiles, improving the transmission efficiency, without the need to pause the transfer of tiles or green bricks, and without causing equipment jitter due to high-speed operation. This solves the problem of the conventional reciprocating moving lifting equipment that when increasing the reciprocating moving speed to improve the transmission efficiency, it will inevitably lead to an increase in equipment jitter, affecting the quality of tiles, and it is difficult to further improve the transmission efficiency due to the limitation of inertial force.

[0052] By fixing the guide plate 2 to the frame 1 and setting the guide plate 2 vertically, when the tile is damaged, small pieces of broken tiles will fall to the ground at the bottom of the frame 1, which is convenient for cleaning, solving the problem of difficult cleaning of broken tiles inside the conventional elevator.

[0053] Preferably, at least two first bearings 431 are sleeved on one end of the first support part 43, at least two of the first bearings 431 are arranged at intervals along the length direction of the first support part 43, a first chute 211 matching the first bearings 431 is arranged in the annular track 21, the first bearings 431 are slidably arranged in the first chute 211, the middle part of the first support part 43 passes through the annular transmission component 3, and the other end of the first support part 43 is connected to the bracket 42.

[0054] As Figure 5 As shown in the figure, the first support part 43 is limited by the cooperation of the first bearings 431 and the first chute 211, realizing the limit of the moving component 4 perpendicular to the transmission direction. By arranging the annular transmission component 3 in the middle of the first support part 43, the first bearings 431 and the bracket 42 are respectively arranged at both ends, and the interval arrangement between the first bearings 431 is adopted to form a multi-point support structure on the first support part 43, making the movement on one side of the bracket 42 more stable and not prone to jitter, solving the problem that the moving component 4 shakes due to the shaking of the chain 32 or encounters small foreign objects in the guide plate 2 during the movement of the moving component 4, causing large jitter of the bracket 42 and affecting the quality of the supported tiles. The first support part 43 is the main support structure of the moving component 4. By setting the connection part of the first support part 43 and the annular transmission component 3 in the middle of the first support part 43 and using multiple first bearings 431, the local stress of the first support part 43 can be effectively reduced, and the overall service life of the moving component 4 can be increased.

[0055] Preferably, a stabilizing slider 432 is provided at one end of the first support portion 43 connected to the bracket 42. The annular track 21 is provided with a second chute 212 that matches the stabilizing slider 432, and the stabilizing slider 432 is movably disposed in the second chute 212. By adding the stabilizing slider 432, the support points of the first support portion 43 are further increased, and the stability of the moving assembly 4 is further increased.

[0056] Preferably, there are three second support portions 44. The distances between the three second support portions 44 and the first support portion 43 are equal, and the three second support portions 44 are evenly distributed around the first support portion 43;

[0057] The cross-section of the guiding track 22 is a C-shaped groove 221. The second support portion 44 is sleeved with a second bearing 441 and a third bearing 442. The outer diameter of the second bearing 441 matches the opening width of the C-shaped groove 221, and the second bearing 441 is slidably disposed at the opening of the C-shaped groove 221. The outer diameter of the third bearing 442 matches the inner width of the C-shaped groove 221, and the third bearing 442 is slidably disposed in the C-shaped groove 221.

[0058] As Figure 6 and Figure 7 As shown, the equilateral triangle structure formed by the three second support portions 44 provides an overall support for the moving assembly 4 to prevent the bracket 42 from tilting. The triangular structure is not prone to deformation and has good overall stability. Through the double-layer structure of the second bearing 441 and the third bearing 442, the smoothness of the second support portion 44 sliding along the guiding track 22 is increased, and the support stability is further increased in cooperation with the C-shaped groove 221 of the guiding track 22. At the same time, it prevents the second support portion 44 from accidentally falling off the second slide rail, solving the problems that the moving assembly 4 cannot ensure balance and the track moving mode is prone to accidental derailment.

[0059] Preferably, the annular transmission assembly 3 includes a first servo motor 31, a chain 32, and at least four gears 33. The chain 32 is arranged along the transmission direction of the annular track 21 to form a closed-loop structure. The gears 33 are disposed on the inner side of the loop of the chain 32. The gears 33 are used to drive and support the chain 32 to be tightened. The output part of the first servo motor 31 is drivingly connected to at least one of the gears 33; the chain 32 is arranged in parallel with a double-layer chain 32, and the gears 33 are double-layer gears 33 corresponding to the chain 32.

[0060] As Figure 2 and Figure 4As shown in the figure, by setting the double-layer chain 32 and precisely controlling it with the first servo motor 31, after the gear 33 tightens the chain 32, when the chain 32 drives the entire moving assembly 4 to move, there will be no reciprocating swing along the transmission direction. It can stably drive the entire moving assembly 4 to move along the transmission direction, and the transmission process is stable, solving the problem that conventional lifting mechanisms are prone to overall jitter during acceleration, deceleration, or high-speed operation, which affects the quality of the supported tiles.

[0061] In one embodiment, both the annular track 21 and the chain 32 are rectangular. Four gears 33 are arranged on the inner sides of the four corners of the rectangular chain 32. The four gears 33 support and tighten the chain 32 from the inner side of the chain 32. The motor is connected to one of the gears 33 to drive the chain 32. The chain 32 is connected to the middle of the first support portion 43 to drive the entire moving assembly 4 to move along the transmission direction.

[0062] Preferably, the chain 32 includes a plurality of chain links 321 and hollow pin shafts 322. The chain links 321 are movably connected through the hollow pin shafts 322. The first support portion 43 is inserted through the hollow pin shafts 322.

[0063] By arranging the first support portion 43 in the hollow pin shaft 322, the first support portion 43 does not affect the rotation between the chain links 321, and at the same time, it can ensure a large contact area to achieve stable transmission connection, avoiding the problem that due to the rotation between the chain links 321 being restricted, the restricted chain links 321 jump when moving to a turning point, resulting in jitter of the moving assembly 4 and affecting the quality of the supported tiles.

[0064] Preferably, it further includes two transmission platforms 5. The transmission platform 5 includes a first sensor, a first driver, a first connecting frame, and a plurality of first rollers. The plurality of first rollers are horizontally arranged on one side of the first connecting frame. In the same transmission platform 5, the plurality of first rollers are arranged at intervals in the same plane. The bracket 42 includes a connecting rod and a plurality of support rods. One end of the support rod is connected to one side in the width direction of the connecting rod, and in the same bracket 42, the plurality of support rods are parallel and arranged at intervals. The other side in the width direction of the connecting rod is connected to the first support portion 43. The first driver is used to drive the first rollers to rotate, and the first sensor is used to sense the position of the tile;

[0065] The interval between the plurality of first rollers of the transmission platform 5 is used to clear the bracket 42, so that the bracket 42 can pass through the transmission platform 5.

[0066] Both the bracket 42 and the transmission platform 5 adopt a single-side support structure, enabling the moving assembly 4 to achieve continuous transmission and increasing the transmission efficiency.

[0067] In one embodiment, when the tile is transported to the low-position transmission platform 5 through the upstream conveyor belt 6, the first roller continues to roll forward to adjust the position of the tile until the first sensor senses that the tile is in place, and then the first roller stops rotating, so that the tile is within the supporting range of the bracket 42, facilitating the smooth lifting of the tile by the bracket 42; when the tile is placed on the high-position transmission platform 5 by the bracket 42, the first sensor senses that the tile is in place, and the first roller starts to rotate to transport the tile to the downstream conveyor belt 7. When the first sensor senses that the tile has left the transmission platform 5, the first roller stops and waits for the next tile to be in place.

[0068] In a specific embodiment, before the transformation, a rocker-type upgrader was used, and the motors adopted were three 1.5kW motors and two 5.5kW motors, with a total power of 15.5kW; after the transformation, a translation-type upgrader was used. Among them, the power of the first servo motor 31 of the annular transmission assembly 3 is 2.2kW, and the first drivers of the two transmission platforms 5 adopt motors with a power of 0.37kW, with a total power of 2.94kW. The power configuration requirements are greatly reduced. By adopting motors with smaller power, the transmission control accuracy is higher, the stability is better, and at the same time, the use cost is lower and the operation noise is smaller.

[0069] Preferably, the moving assembly 4 includes a second sensor, a second driver, a second connecting frame, and a plurality of second rollers. The plurality of second rollers are horizontally arranged on the second connecting frame, and the plurality of second rollers in the same bracket 42 are arranged in the same plane. The second driver is used to drive the second rollers to rotate, and the second sensor is used to sense the position of the tile on the bracket 42;

[0070] It further includes a third sensor, and the third sensor is electrically connected to the annular transmission assembly 3. The third sensor is used to sense the position of the bracket 42.

[0071] In another embodiment, when the bracket 42 moves to be flush with the upstream conveyor belt 6, the third sensor is triggered, and the annular transmission assembly 3 stops the movement of the moving assembly 4. The rollers on the bracket 42 roll in the tile. After the second sensor senses that the tile is in place, the annular transmission assembly 3 starts again to drive the moving assembly 4 to move; when the bracket 42 supporting the tile on it moves to be flush with the downstream outgoing conveyor belt, the third sensor is triggered, and the annular transmission assembly 3 stops the movement of the moving assembly 4. The rollers on the bracket 42 roll out the tile. After the second sensor senses that the tile has been rolled out, the annular transmission assembly 3 starts again to drive the moving assembly 4 to move again.

[0072] The incoming and outgoing movement of the tile is realized through the rollers on the bracket 42, and there is no need to additionally set up a transmission platform 5. The equipment installation is more flexible, and at the same time, the incoming and outgoing of the tile is smoother, which can further improve the quality of the tile.

[0073] In a specific embodiment, the second driver uses a 0.37 kW motor.

[0074] Preferably, the length direction of the connecting rod or the second connecting frame is arranged parallel to the incoming and outgoing directions of the tiles. The length of the connecting rod or the second connecting frame is 800 mm, and the length of the supporting rod or the second roller is 1300 mm.

[0075] The number of brackets 42 running simultaneously on the guide plate 2 is limited by the minimum distance between the brackets 42. By setting the connecting rod or the second connecting frame as the shorter side, it is possible to avoid interference between the brackets 42 at the turning points. By setting the shorter side parallel to the incoming and outgoing directions of the tiles, the incoming and outgoing distances of the tiles are shortened, and the tile transfer time can be shortened at the same incoming and outgoing speeds. By the above structure, the distance between the brackets 42 is reduced, the number of brackets 42 used simultaneously in the guide plate 2 is increased, and the transmission efficiency is increased.

[0076] In a specific embodiment, the length of the tiles to be transported and lifted is 910 - 1310 mm, and the width is 810 - 610 mm. The length and width of the bracket 42 are set such that a single tile can be placed on it without generating hidden cracks. The optimal distance between adjacent brackets 42 is designed to be 1.1 meters. Compared with the output of a conventional rocker-type elevator, which is approximately 6000 square meters per day, the output of the translational elevator can reach 10000 square meters per day, and the transmission efficiency is increased by 66%.

[0077] Preferably, the frame 1 includes a first lifting frame 11 and a second lifting frame 12, and the two transmission platforms 5 are respectively arranged on the first lifting frame 11 and the second lifting frame 12 in a liftable manner.

[0078] As Figure 8 shown, in one embodiment, the first lifting frame 11 is arranged close to the upstream conveyor belt 6, and the second lifting frame 12 is arranged close to the downstream conveyor belt 7. By adjusting the height of the transmission platform 5 through the first lifting frame 11 and the second lifting frame 12, it is possible to adapt to the upstream conveyor belt 6 and the downstream conveyor belt 7 with different heights, facilitating adaptation to different production and transportation scenarios.

[0079] Preferably, the bracket 42 adopts a rubber sleeve structure.

[0080] Specifically, a buffer rubber layer is sleeved on the supporting rod, the first roller or the second roller. Through the rubber sleeve structure, the impact force when the bracket 42 holds up the tiles is reduced, preventing the tiles from cracking due to excessive impact force.

[0081] A method for lifting and transporting tiles, using the above-mentioned translation elevator, controls the moving speed of the moving component 4 through the annular transmission component 3, runs at 15-25 meters per minute for 1-5 seconds, then decelerates for 1-3 seconds to 0-10 meters per minute, maintains the operation at 0-10 meters per minute for 1-3 seconds, and then accelerates for 1-3 seconds to restore the running speed of 15-25 meters per second, and so on in a cycle. And the bracket 42 is set to pass through the incoming and outgoing positions of the tiles during the 1-3 second interval of maintaining the operation at 0-15 meters per minute.

[0082] In a specific embodiment, it is controlled by the first servo motor 31 in the annular transmission component 3 in cooperation with the PLC program, and is linked with the upstream conveyor belt 6 and the downstream conveyor belt 7 to drive the moving component 4 to achieve acceleration and deceleration movement.

[0083] By controlling the moving speed of the moving component 4 and the acceleration during acceleration and deceleration, the bracket 42 decelerates when lifting and lowering the tiles to handle them gently, ensuring that the force on the tiles does not exceed the process limit during the overall transportation and lifting process, and accelerating to the maximum running speed during the operation process to improve the transportation efficiency.

[0084] In an embodiment, the translation elevator is provided with two transmission platforms 5 at high and low positions. The single press is 6 times per minute and presses one tile at a time, which means that it takes within 10 seconds for the bracket 42 to lift one tile until the next tile is lifted, so as to meet the transmission and lifting requirements of the single press. After the bracket 42 lifts a tile from the low-position transmission platform 5, the moving component 4 accelerates to 20 meters per minute in 2 seconds, and then the next tile is introduced into the low-position transmission platform 5 from the upstream conveyor belt 6 again in 2 seconds. During this period, the moving component 4 moves at a constant speed for 6 seconds, and then the speed of the moving component 4 is reduced to 0 after 2 seconds of deceleration. At this time, the bracket 42 of the next moving component 4 passes by and lifts the next tile on the low-position transmission platform 5, and so on in a cycle; in addition, by adjusting the spacing of the brackets 42 to match the distance between the two transmission platforms 5 along the transmission direction, when the bracket 42 of one moving component 4 lifts a tile from the low-position transmission platform 5, the bracket 42 of the other moving component 4 just puts down another tile on the high-position transmission platform 5, and the transmission platform 5 transfers the tile to the downstream conveyor belt 7 in 2 seconds to achieve the stable putting down and transfer of the tile.

[0085] In another embodiment, the translational elevator is provided with two transmission platforms 5 at high and low positions. The single press machine operates 6 times per minute and presses one tile at a time. After the bracket 42 holds up one tile, the moving component 4 accelerates to 25 m / min in 2 seconds, and then the next tile is fed into the lifting range from the upstream conveyor belt 6 again in 2 seconds. During this period, the moving component 4 moves at a constant speed for 6 seconds, and then after 2 seconds of deceleration, the speed of the moving component 4 is reduced to 10 m / min. At this time, the bracket 42 of the next moving component 4 holds up the tile in the lifting range, and so on in a cycle. During the entire transmission process, the moving component 4 only decelerates without pausing. Although the force on the tile increases during the transmission process, the overall transmission efficiency can be greatly improved.

[0086] In another embodiment, a motor and a roller are provided on the bracket 42 of the translational elevator. The single press machine operates 6 times per minute and presses one tile at a time. After the bracket 42 holds up one tile, the moving component 4 accelerates to 15 m / min in 3 seconds. During this period, the moving component 4 moves at a constant speed for 2 seconds, and then after 3 seconds of deceleration, the speed of the moving component 4 is reduced to 0. Then, the upstream conveyor belt 6 and the roller of the bracket 42 cooperate, and the next tile is fed into the bracket 42 again in 2 seconds. At this time, the bracket 42 of the next moving component 4 holds up the tile again, and so on in a cycle to achieve the stable feeding, lifting and hoisting of the tile; similarly, the bracket 42 cooperates with the downstream conveyor belt 7 to achieve the stable dropping and discharging of the tile. Although it is necessary to pause and wait for the tile to be fed in and discharged, the cooperation accuracy between the bracket 42 and the upstream conveyor belt 6 and the downstream conveyor belt 7 is higher, the feeding and discharging of the tile are smoother, the force on the tile during the entire transmission process is smaller, the product quality is higher, and at the same time, the transmission efficiency can be improved by increasing the number of brackets 42 running simultaneously, and a transmission efficiency similar to that of the solution using the transmission platform 5 can be obtained and used.
