Description

Technical Field

[0001] The present invention relates to the technical field of transmission systems, and specifically to a transmission system with a long service life and that does not damage the bottom surface of the board. Background Art

[0002] Transmission systems are used to transport various materials and are widely applied in workshops. For example, the ALC firewall boards, ALC floor boards, ALC exterior wall boards, etc. produced by the applicant are all transported from the manufacturing workshop to the external warehouse through multiple chain conveyors.

[0003] Previously, the applicant applied for a transition device for a board transportation line, with the patent application number CN202021199541.9, which is applied to such chain conveyors. This transition device solves the risk of bumping during the transmission of ALC boards. When the chain conveyor transports ALC boards, a supporting plate fixedly connected to the chain is fixed on the conveying chain. A groove is provided inside the supporting plate, and a rubber block is embedded in the groove. Bolt holes are provided in the vertical direction between the rubber block and the supporting plate, and the rubber block is fixed on the supporting plate through bolts.

[0004] However, since the bundled ALC boards are relatively heavy, when they are pressed on the supporting plate and transported outwards, the supporting plate moves forward under the pulling force of the transmission device, and a large backward static friction force will be generated between the placed ALC boards and the supporting plate, and a large shear force will be generated on the vertically fixed bolts. After a long time, the bolts will be cut off and the rubber blocks will be rubbed out of the supporting plate.

[0005] On the currently used transportation line, the rubber blocks are seriously lost and damaged, and only the supporting plate is in direct contact with the ALC board. For the remaining supporting plates with rubber blocks, in order to prevent the rubber blocks from detaching from the supporting plate, the employees use multiple iron bars to tie the rubber blocks and the supporting plate together, as shown in Figure 1 shown. This causes the height of the upper surface of the conveyor line to be uneven. In some cases, the supporting plate is in direct contact with the ALC board, and in some cases, the rubber block is in contact with the ALC board. The iron bars are wound around the outside of the rubber block, and the direct contact between the iron bars and the supporting plate and the ALC board will cause varying degrees of damage to the bottom surface of the ALC board.

[0006] In addition, the distance from the workshop to the external warehouse is very long, and the lines of multiple conveyors are very long. It is very labor-consuming to rely on manual inspections to monitor which rubber block has fallen off the conveyor. Therefore, the applicant has improved the overall transmission system. Summary of the Invention

[0007] To solve the technical problems existing in the above background art, the present invention provides a transmission system with a long service life and that does not damage the bottom surface of the board.

[0008] The technical solution of the present invention is as follows:

[0009] A transmission system with a long service life and no damage to the bottom surface of the board, including several conveyor belts assembled on the outside of the conveyor frame, used for transporting materials above it. There is a transition device between two adjacent conveyor belts. The transition device includes a transition roller. In this application, the supporting plate fixedly installed on the conveyor belt is replaced with a supporting roller connected by rotation, and a flipping device is arranged on the side close to the rear conveyor belt below the transition device to assist the supporting roller in flipping, and a detection module is relied on to detect the deformation condition of the outer surface of the supporting roller in real time.

[0010] Specifically, several supporting rollers are installed on the outer side of the conveyor belt, and the axis of the supporting roller is set perpendicular to the conveying direction of the conveyor belt.

[0011] The supporting roller includes a supporting shaft inside, a supporting bracket in the middle, and a filling block outside. The supporting shaft includes a middle shaft and more than three groups of abutting blocks arranged in an array on the outer ring. The supporting bracket includes several supporting bars with the same number as the abutting blocks. The several supporting bars are arranged in an array on the outside of the supporting shaft, and the positions at both ends of adjacent supporting bars are fixed by connecting plates. The distance between adjacent supporting bars is greater than the width of the abutting block. The abutting block can only rotate between two adjacent supporting bars. The filling block is filled between adjacent supporting bars and can abut against the abutting block to press the abutting block down against the side wall of the supporting bar. The filling block protrudes above the supporting bracket.

[0012] Both ends of the middle shaft extending out of the supporting bracket are respectively connected with bearing seats, and the bearing seats are installed on the conveyor belt.

[0013] In this way, the lower bottom surface of the ALC board contacts the outer surface of the filling block, and the lower bottom surface of the ALC board will not be damaged. The filling block does not need to be fixed on the rigid supporting bracket with iron bars or bolts. Since the filling blocks are evenly distributed between adjacent supporting bars and form an outer ring around the supporting shaft, soft connecting pieces can be arranged on both end faces of the filling block to connect adjacent filling blocks, so that it is sleeved around the outside of the supporting shaft in a ring shape, not restricted by rigid connection, and can deform better to contact the ALC board.

[0014] In addition, when the conveyor belt drives the bearing seat to move, the bearing seat pulls the supporting shaft to move. The abutting blocks on the outside of the supporting shaft abut against the supporting bars of the supporting bracket, and the supporting shaft and the supporting bracket form an integral structure to jointly bear the pressure from the ALC board, ensuring the supporting effect. At the same time, the supporting shaft is rotationally connected to the bearing seat. After the plurality of filling blocks are transported in a circle, different filling blocks will turn upwards to support the ALC board, or the flipping device is used to assist the supporting roller in flipping, and different filling blocks can also be changed to face upwards, thereby improving the service life of the filling blocks.

[0015] To better realize the rotation of the supporting roller, the number of abutting blocks and supporting bars is designed to be four.

[0016] Furthermore, the support bars are designed as rectangular solid bars, with the long sides and short sides of adjacent rectangular bars arranged perpendicularly, and the outer boundary formed by the four rectangular bars and the connecting plate being a square. Thus, after the filling block is inserted between adjacent rectangular bars, the thicknesses of the filling block near the long side and near the short side are different. By designing its thinner end to face the conveying direction of the conveyor belt, the direction of the static friction force can be made to face the thicker end of the filling block, which can further improve the service life of the filling block.

[0017] Regarding the design of the supporting shaft, the inside of the abutting block is connected to the supporting shaft, and the two ends of the outwardly protruding part on the outside are respectively a straight section and a curved section, and the farthest point from the center of the central axis of each abutting block is the point at one end of the straight section close to the curved section. And the straight section is designed to be perpendicularly abutted against the long side of the rectangular bar. In this way, when the abutting block rotates to the limit position, the end of the straight section close to the curved section abuts against the long side of the rectangular bar, and no other parts of the abutting block will interfere with the rectangular bar during the rotation process. Of course, a connecting section perpendicular to the straight section can also be added between the straight section and the curved section to increase the abutting area between the abutting block and the rectangular bar. However, correspondingly, this will reduce the thickness of the filling block on the side of the straight section, affecting the degree of the filling block's resistance to static friction. The length selection of the connecting section can be determined according to the specific size of the supporting roller.

[0018] Preferably, the straight sections of adjacent two abutting blocks are perpendicular to each other, and the foot of the perpendicular falls on the straight section. Through this design, it can be further ensured that the straight section of the abutting block has sufficient length, which can not only leave enough supporting surface to support the filling block, but also increase the area of the filling block on the side facing the direction of the static friction force, facilitating the filling block to better bear the friction force with the ALC.

[0019] Regarding the design of the filling block, the filling block includes an upper filling part and a lower inserting part. Among them, the width of the upper filling part is greater than the single-sided width of the square supporting bracket, the lower end is attached to the upper surface of the supporting bracket, and the width of the lower inserting part is matched with the distance between adjacent rectangular bars, and the lower end is attached to the outer surface of the supporting shaft.

[0020] Furthermore, the thickness of the contact part of the filling block with the straight section of the abutting block is greater than the thickness of the contact part with the curved section of the abutting block.

[0021] The flipping device in this transmission system is located between adjacent conveyor belts, arranged close to the rear conveyor belt, with a height lower than the center position of the conveyor belt, and within the rotation trajectory of the supporting roller, and can push the filling block to rotate around the supporting shaft. Thus, every time the supporting roller rotates one circle, different filling blocks will be flipped to face upwards.

[0022] The detection module in this transmission system is located inside the conveyor rack and is set below the upper surface of the conveyor belt. The detection module includes a ranging sensor for detecting the height of the upper or lower surface of the filling block. The detection module is connected to the control unit through wires and feeds back the detected height of the upper or lower surface of the filling block to the control unit. The control unit compares the detected data with the predefined values in the system. If the detected value deviates from the predefined value, it may indicate that the filling block is damaged, and it can be replaced in a timely manner.

[0023] Through the above design, the lower bottom surface of the ALC board in the transmission system of the present invention contacts the outer surface of the filling block, and the lower bottom surface of the ALC board will not be damaged. The filling blocks do not need to be fixed on the rigid support brackets using iron bars or bolts. Since the filling blocks are evenly distributed between adjacent support bars and form an outer ring around the support shaft, soft connecting pieces can be provided on both end faces of the filling blocks to connect adjacent filling blocks, enabling them to be annularly sleeved outside the support shaft, without being restricted by rigid connections, and can deform better to contact the ALC board.

[0024] In addition, when the conveyor belt drives the bearing seat to move, the bearing seat pulls the support shaft to move. The abutting block on the outer side of the support shaft abuts against the support bar of the support bracket, and the support shaft and the support bracket form an integral structure to jointly bear the pressure from the ALC board, ensuring the support effect. At the same time, the support shaft is rotatably connected to the bearing seat. After multiple filling blocks are transported in a circle, different filling blocks will be rotated upwards to support the ALC board. Or, the auxiliary support roller can be flipped through a flipping device, and different filling blocks can also be rotated upwards, thereby increasing the service life of the filling blocks.

[0042] Refer to Figures 2 - 6 , this embodiment provides a transmission system with a long service life and no damage to the bottom surface of the plate, including a plurality of conveyor belts 1. The conveyor belts 1 are chain conveyor belts, assembled on the outside of the conveying frame 3, and are used for transporting materials above it. A transition device 4 is provided between two adjacent conveyor belts 1, and the transition device 4 includes a transition roller 42.

[0043] Further, the conveying rack 3 includes side brackets 31 on both sides. A number of connecting frames 32 are connected between the two side brackets 31. The two ends of the connecting frame 32 extend out of the side brackets 31 and then extend downward, and rollers are provided at the bottom. Rotating shafts 33 are respectively arranged at both ends of the side brackets 31. Gears are connected to both ends of the rotating shafts 33. The chain conveyor belt 1 is sleeved outside the side brackets and is respectively sleeved on the gears of the rotating shafts 33 at both ends. One end of the rotating shaft 33 is connected to a motor 34. The rotating shaft 33 is driven to rotate by the motor 34, and then the chain conveyor belt is driven to act. The transmission directions of adjacent conveyor belts are the same.

[0044] Further, the transition device 4 includes a connecting frame 32 fixed to the outside of the side bracket 31. A transition roller 42 is provided in the middle position. The transition roller 42 is located in the middle position between two adjacent conveyor belts 1, and its height is the same as the height of the support rollers 2 installed on the conveyor belt.

[0045] In this application, the original fixed support plate on the conveyor belt 1 is replaced with a rotatably connected support roller 2, and a flipping device 5 is provided on the side close to the rear conveyor belt 1 below the transition device 4 to assist the support roller 2 to flip. See the attached Figure 12 . And the detection module 7 is relied on to detect the deformation condition of the outer surface of the support roller 2 in real time.

[0046] Specifically, a number of support rollers 2 are installed on the outer side of the conveyor belt 1. The axis of the support roller 2 is set perpendicular to the conveying direction of the conveyor belt 1.

[0047] The support roller 2 includes a supporting shaft 21 inside, a supporting bracket 22 in the middle, and a filling block 23 outside. The supporting shaft 21 includes a middle shaft 211 and four groups of abutting blocks 212 arranged in an array on the outer ring. See Figure 9 and Figure 10 as shown. The supporting bracket 22 includes four solid rectangular bars 221. The four rectangular bars 221 are arranged in an array outside the supporting shaft 21, and the two ends of adjacent rectangular bars 221 are fixed by connecting plates 222. The distance between adjacent rectangular bars 221 is greater than the width of the abutting block 212. The abutting block 212 can only rotate between two adjacent rectangular bars 221. The filling block 23 is filled between adjacent rectangular bars 221 and can abut against the abutting block 212 to press the abutting block 212 down to abut against the side wall of the rectangular bar 221. The filling block 23 protrudes above the supporting bracket 22.

[0048] Further, the length of the middle shaft 211 is greater than the length of the abutting block 212. The parts of the middle shaft 211 extending out of the supporting bracket 22 at both ends are respectively connected with bearing seats 24. Sleeve 25 is sleeved on both ends of the middle shaft 211. The bearing seats 24 are installed on the conveyor belt 1.

[0049] Preferably, both ends of the middle shaft 211 extend out of the bearing seats 24 and are respectively sleeved with anti-collision blocks 26.

[0050] In this way, the lower bottom surface of the ALC board 6 contacts the outer surface of the filling block 23, without damaging the lower bottom surface of the ALC board 6. The filling block 23 does not need to be fixed to the rigid support bracket 22 using iron bars or bolts. Since the filling blocks 23 are evenly distributed between adjacent support bars and form an outer ring around the support shaft 21, flexible connectors can be provided on both end faces of the filling block 23 to connect adjacent filling blocks 23, so that they are annularly sleeved outside the support shaft 21, without being restricted by rigid connections, and can be deformed better to contact the ALC board 6.

[0051] In addition, when the conveyor belt 1 drives the bearing block 24 to move, the bearing block 24 pulls the support shaft 21 to move, and the abutting block 212 on the outer side of the support shaft 21 abuts against the support bar of the support bracket 22. The support shaft 21 and the support bracket 22 form an integral structure to jointly bear the pressure from the ALC board 6 material, ensuring the support effect. At the same time, the support shaft 21 is rotatably connected to the bearing block 24, and a turning device 5 is provided at the end of the conveyor belt 1 to assist the support roller 2 to turn. After the plurality of filling blocks 23 are transported in a circle, different filling blocks 23 will be turned upwards to support the ALC board 6, thereby improving the service life of the filling blocks 23.

[0052] See Figure 7 and Figure 8 In this embodiment, the number of the abutting blocks 212 and the rectangular bars 221 is four. The support bar is designed as a rectangular solid bar, and the long sides and short sides of adjacent rectangular bars 221 are arranged vertically. The outer boundary formed by the four rectangular bars 221 and the connecting plate is a square. Thus, after the filling block 23 is inserted between adjacent rectangular bars 221, the thickness of the filling block 23 on the side close to the long side and the side close to the short side is different. By designing the thinner end to face the conveying direction of the conveyor belt 1, the direction of the static friction force can be made to face the thicker end of the filling block 23, which can further improve the service life of the filling block 23.

[0053] Furthermore, in this embodiment, it is set that the upper rectangular bar 221 on the side of the support bracket 22 facing the moving direction of the conveyor belt 1 is horizontally arranged, and correspondingly, the rectangular bar 221 at its rear end is vertically arranged. See Figure 7 As shown, the vertically arranged rectangular bar 221 in the upper left corner is defined as the first rectangular bar 2211, arranged clockwise, the horizontally arranged one in the upper right corner is the second rectangular bar 2212, the vertically arranged one in the lower right corner is the third rectangular bar 2213, and the horizontally arranged one in the lower left corner is the fourth rectangular bar 2214. Since the front end of the filling block 23 on the upward side abuts against the short side of the horizontally arranged second rectangular bar 2212, and the rear end abuts against the long side of the vertically arranged first rectangular bar 2211, the thickness of the rear end of the filling block 23 must be greater than the thickness of the front end. Also, since the direction of the static friction force is opposite to the moving direction of the conveyor belt 1 and faces the thicker direction of the rear end of the filling block 23, therefore, the filling block 23 can better withstand the static friction force, improving the service life of the filling block 23.

[0054] Based on the design of the above-mentioned supporting bracket 22, refer to Figure 7 and Figure 10 . Regarding the design of the supporting shaft 21, the inside of the abutting block 212 is connected to the supporting shaft 21, and the two ends of the outwardly protruding part of the outside are respectively a straight line segment 2121 and a curved line segment 2122, and the farthest point of each abutting block 212 from the center of the central axis is the point of the straight line segment 2121 close to one end of the curved line segment 2122.

[0055] Furthermore, the farthest distance of each abutting block 212 from the center of the central axis 211 is greater than the nearest distance between the center of the central axis 211 and the rectangular strip 221. In this way, the abutting block 212 can be restricted to rotate only between two adjacent rectangular strips 221.

[0056] Furthermore, when the abutting block 212 rotates to the limit position between two adjacent rectangular strips 221, it is designed that the straight line segment 2121 abuts perpendicularly against the lower part of the long side of the rectangular strip 221. In this way, when the abutting block 212 rotates to the limit position, one end of the straight line segment 2121 close to the curved line segment 2122 abuts against the long side of the rectangular strip 221, and other parts of the abutting block 212 will not interfere with the rectangular strip 221 during the rotation process.

[0057] Preferably, a connecting segment perpendicular to the straight line segment 2121 (not shown in the figure) is further provided between the straight line segment 2121 and the curved line segment 2122 to increase the abutting area between the abutting block 212 and the rectangular strip 221. However, correspondingly, this will reduce the thickness of the filling block 23 on one side of the straight line segment 2121 and affect the degree of the filling block 23 resisting static friction. Therefore, the abutting height between the straight line segment 2121 on the left side of the intermediate shaft 211 and the first rectangular strip 2211 is designed not to be higher than the lower end height of the horizontally arranged second rectangular strip 2212, and the rest of the straight line segments are the same by analogy. In this way, both the thickness of the filling block on the side facing the static friction direction is ensured, and the sufficient abutting area between the abutting block 212 of the supporting shaft 21 and the supporting bracket 22 can be ensured, and the pressure of the ALC board can be better jointly borne.

[0058] As a further preference, the straight line segments 2121 of two adjacent abutting blocks 212 are perpendicular to each other, and the foot of the perpendicular falls on the straight line segment 2121. Through this design, the sufficient length of the straight line segment 2121 of the abutting block 212 can be further ensured, which can not only leave enough supporting surface to support the filling block 23, but also increase the area of the filling block 23 on the side facing the static friction direction, facilitating the filling block 23 to better bear the friction with the ALC.

[0059] Refer to Figure 11, Regarding the design of the filling block 23, the filling block 23 includes an upper filling portion 231 and a lower insertion portion 232. Among them, the width of the upper end of the upper filling portion 231 is greater than the single-sided width of the square supporting bracket 22, and the lower end is attached to the upper surface of the supporting bracket 22. Side inclined surfaces 2311 are provided on both sides of the upper filling portion 231, and the inclination angle of the side inclined surfaces 2311 is 45 degrees, which is convenient for the side inclined surfaces 2311 of adjacent filling blocks 23 to be pressed together.

[0060] Furthermore, the width of the lower insertion portion 232 is matched with the spacing between adjacent rectangular strips 221, and the lower end is attached to the outer surface of the supporting shaft 21.

[0061] Furthermore, short straight edges 2312 and long straight edges 2313 are respectively provided on the left and right sides of the lower insertion portion 232 on the lower surface of the upper filling portion 231, and the dimensions of the short straight edges 2312 and the long straight edges 2313 are respectively matched with the short side and the long side dimensions of the rectangular strip 221. Preferably, the top of the upper filling portion 231 is designed as an arc, and the center of the circle faces the lower insertion portion 232. When the upper filling portion 231 is pressed down by the ALC board, the center of gravity of the filling block 23 moves downward. On the one hand, the downward pressure will make the filling block 23 contact the supporting shaft 21 more closely. On the other hand, both ends of the filling block 23 will transfer the gravity to adjacent filling blocks 23 through the side inclined surfaces 2311, so that the entire support roller 2 can jointly bear the gravity.

[0062] Furthermore, the lower insertion portion 232 is divided into a long side contact portion 2321 and a short side contact portion 2322. Among them, the width of the long side contact portion 2321 is the same as the width of the straight line segment 2121, and the height is slightly less than the long side height of the rectangular strip 221, and is matched with the dimension of the distance from the straight line segment 2121 to the top of the first rectangular strip 2211. The width of the short side contact portion 2322 is matched with the dimension of the curved line segment 2122, the height of one side is matched with the short side height of the second rectangular strip 2212, and the height of the other side is the same as the height of the long side contact portion 2321. Thus, the thickness of the contact portion between the filling block 23 and the straight line segment 2121 of the abutting block 212 is greater than the thickness of the contact portion between the filling block 23 and the curved line segment 2122 of the abutting block 212.

[0063] Furthermore, connection holes 2314 are respectively provided at the left and right ends of the upper filling portion 231, and adjacent two filling blocks 23 can be connected through a flexible connecting piece, so that 4 filling blocks 23 form an integral structure.

[0064] Next, refer to Figure 7To introduce the special purpose of the above design, the moving direction of the conveyor belt 1 is towards the right. After the supporting shaft 21 is inserted into the supporting bracket 22 and rotated counterclockwise, its straight section 2121 can be vertically clamped on the long side of the rectangular strip 221 in the support frame 2. At this time, the conveyor belt 1 will pull the supporting shaft 21 connected to the bearing seat 24 and apply a pulling force F1 to the right on the supporting shaft 21. After the ALC board presses on the upper filling block 23, the upper filling block 23 receives a static friction force F2 to the left. At the same time, the gravity F3 of the ALC board presses on the filling block 23. Under the simultaneous influence of the downward pressure F3 and the leftward static friction force F2, the filling block 23 forms a resultant force obliquely downward to the left. Thus, after the pressure F3 is transmitted to the supporting shaft 21, the resultant force obliquely downward to the left presses downward on the supporting shaft 21, only causing it to have a tendency to rotate counterclockwise, and this tendency will only make the tight fit between the supporting shaft 21 and the support frame 2 more solid. Therefore, when the support roller 2 drags the ALC board forward, there is no relative movement between the supporting shaft 21 and the support frame 2, forming an integral structure.

[0065] To better flip the support roller 2 and make different filling blocks 23 face upward to support the ALC board, a flipping device 5 is specially provided in this transmission system. It is located between adjacent conveyor belts 1 and is arranged close to the rear conveyor belt 1. See Figure 12 as shown.

[0066] See Figure 13 and Figure 14 , the flipping device 5 includes two vertically arranged telescopic columns 51. The telescopic column 51 is composed of two sleeves slidingly connected, and a spring 54 is provided inside it. The tops of the two telescopic columns 51 are connected with a horizontally arranged flipping rod 52, and the bottom is fixed to the ground through a base 53.

[0067] In the natural state, the height of the flipping rod 52 is lower than the center position of the conveyor belt 1, within the rotation trajectory of the support roller 2, and the distance from the edge of the conveyor belt 1 is greater than half of the total height of the support roller 2 and less than the total height of the support roller 2. Thus, when the support roller 2 finishes transporting the ALC board and flips downward, the outer end of the rotationally connected filling block 23 will touch and press down the flipping rod 52, causing the top of the telescopic column 51 to move vertically downward. At the same time, the supporting shaft 21 rotates around the bearing seat. When the lower edge of the filling block 23 receives an upward rebounding force from the spring in the flipping device 5, it will rotate counterclockwise until the adjacent filling block 23 is flipped upward and then moves away from the flipping device 5. Thus, for each rotation of the support roller 2, different filling blocks 23 can be flipped upward, enabling each filling block 23 to be evenly stressed and improving the service life of the support roller 2.

[0068] The detection module of this embodiment is located on the side of the connecting frame 32 inside the conveyor frame 3, and is arranged below the upper surface of the conveyor belt 1. The detection module includes an infrared ranging sensor 71 and an ultrasonic ranging sensor 72, which are used to detect the height of the upper surface or the lower surface of the filling block 23. For example, along the conveying direction of the conveyor belt 1, the infrared ranging sensor 71 is located at the rear end of the ultrasonic ranging sensor 72. First, the infrared ranging sensor 71 detects the passing of the support roller 2, and then the ultrasonic ranging sensor 72 is turned on after a preset time interval to detect the height of the passing support roller 2 above.

[0069] Preferably, the number of ultrasonic ranging sensors 72 is 2, which are respectively located near the side brackets 31 at both ends of the connecting frame 32 to improve the accuracy of information collection.

[0070] Furthermore, the detection module is connected to the control unit through wires, and feeds back the detected height of the upper surface or the lower surface of the filling block 23 to the control unit. The control unit compares the detection data with the predefined values in the system. If the detected value deviates from the predefined value, it may indicate that the filling block 23 is damaged, and it can be replaced in time.
