Description

Technical Field

[0001] The present application relates to the field of conveying equipment, and in particular to a conveying line switching device and conveying equipment. Background Art

[0002] In the tile production process, it is crucial to accurately sort tiles of different qualities and shapes and transport them to conveyor lines at different heights. The traditional upper and lower layer tile separation device relies on a cylinder to drive a linear lifting frame to transfer tiles from the lower layer to the upper layer. In specific operation, when the moving number of tiles (usually 2-3 pieces) are transported to the lifting frame, the conveying motor pauses and the cylinder starts immediately to lift the lifting frame carrying the tiles upward until it is aligned with the upper inclined conveyor line frame. After that, the motor restarts and transports the tiles along the inclined line frame to the target position.

[0003] However, the cylinders must simultaneously bear the combined weight of the lifting frame and the tiles. This heavy load leads to accelerated wear, frequent failures, and increased maintenance costs. Furthermore, the time-consuming lifting and conveying processes result in inefficient tile separation, making it difficult to meet the high-speed operation requirements of modern tile production lines. Furthermore, slow tile separation speeds can easily cause tile blockages, impacting the smooth operation of the production line. Utility Model Content

[0045] In the process of producing tiles, in order to distinguish tiles of different qualities or to stack tiles, it is necessary to divert the tiles, that is, to transport the tiles on one conveyor line to another conveyor line, especially for two conveyor lines of different heights. The tiles are usually driven up and down by a cylinder, but long-term direct driving of the cylinder to lift and lower will cause accelerated wear of the cylinder, prone to failure, and increase maintenance costs. For this reason, the application uses the driving member 110 as the power source, and then transmits the power to the rotating shaft 130 through the connecting rod structure 120, so that the rotating shaft 130 rotates. The rotation of the rotating shaft 130 drives the mounting rod 140 and the roller structure 150 to rotate, so that the height of the roller structure 150 changes, and then the roller structure 150 guides the tiles from the lower conveyor line to the higher conveyor line, completing the switching between two different conveyor lines.

[0046] It should be noted that the product being transported in this application is ceramic tiles. The ceramic tiles can be replaced with other plate-like products according to actual needs. The specific plate-like products are not limited here.

[0047] The present application discloses a conveyor line switching device 100 , which includes a driving member 110 , a connecting rod structure 120 , a rotating shaft 130 , a mounting rod 140 , and a roller structure 150 .

[0048] The driving member 110 has a rotating end, the power input end of the connecting rod structure 120 is connected to the rotating end of the driving member 110, the rotating shaft 130 is connected to the power output end of the connecting rod structure 120, the connecting rod structure 120 is used to drive the rotating shaft 130 to rotate, the mounting rod 140 is fixedly installed on the rotating shaft 130, and the roller structure 150 is installed at the end of the mounting rod 140 away from the rotating shaft 130.

[0049] See Figures 1 to 3As shown, the power from the driving member 110 is transmitted to the rotating shaft 130 through the connecting rod structure 120, thereby driving the rotating shaft 130 to rotate a certain angle. Since the rotating shaft 130 rotates a certain angle, it will also drive the mounting rod 140 and the roller structure 150 to rotate. For this reason, the height of the roller structure 150 gradually increases to press against the bottom surface of the tile. The tile is guided by the roller structure 150 and the conveying force of the conveying line and is conveyed to another conveying line, realizing the switching between two different conveying. This process can be referred to Figure 7 shown.

[0050] In this embodiment, the two conveyor lines are at different heights, and the tiles at the lower position need to be transported to the higher conveyor line through the guidance of the roller structure 150 to complete the switching of tiles on different conveyor lines.

[0051] Furthermore, the driving member 110 is a motor, specifically a servo motor. In order for the motor to output a larger torque, a reducer can be installed on the output shaft of the motor, which can reduce the speed of the motor to a certain extent and increase the output torque to meet the need of driving the rotating shaft 130 to rotate. The reducer can be a worm gear reducer, a planetary reducer, etc., which can be selected according to actual needs and is not limited here.

[0052] The connecting rod structure 120 includes a first transmission rod 121, a connecting rod 122 and a second transmission rod 123. The first transmission rod 121 is connected to the rotating end of the driving member 110, the connecting rod 122 is installed on the first transmission rod 121, and the second transmission rod 123 is installed at the end of the connecting rod 122 away from the first transmission rod 121. The end of the second transmission rod 123 away from the connecting rod 122 is installed and connected to the rotating shaft 130.

[0053] See Figures 1 to 3 As shown, in order to drive the rotating shaft 130 to rotate a certain angle each time, one end of the connecting rod 122 is rotatably installed on the first transmission rod 121, and then the other end of the connecting rod 122 is rotatably installed on the second transmission rod 123. For this reason, when the driving member 110 drives the first transmission rod 121 to rotate, it will drive the connecting rod 122 to reciprocate, and the reciprocating motion of the connecting rod 122 drives the second transmission rod 123 to rotate a certain angle, thereby driving the rotating shaft 130 to rotate a certain angle, thereby driving the installation rod 140 and the roller structure 150 to rotate a certain angle with the rotating shaft 130 as the rotation center, and realizing the roller structure 150 to rise or fall reciprocatingly, thereby realizing the guiding support for the tiles.

[0054] A first rotating connector 124 is provided between the connecting rod 122 and the first transmission rod 121 , and the first transmission rod 121 and the connecting rod 122 are connected via the first rotating connector 124 .

[0055] A second rotating connector 125 is provided between the connecting rod 122 and the second transmission rod 123 , and the connecting rod 122 and the second transmission rod 123 are connected via the second rotating connector 125 .

[0056] Continue reading Figures 1 to 3 As shown, in order to enable the connecting rod 122 and the first transmission rod 121 to rotate relative to each other, the first transmission rod 121 and the connecting rod 122 are connected by a first rotating connector 124. Similarly, in order to enable the connecting rod 122 and the second transmission rod 123 to rotate relative to each other, the connecting rod 122 and the second transmission rod 123 are connected by a second rotating connector 125. In this embodiment, the first rotating connector 124 and the second rotating connector 125 are both joint bearings, that is, one end is fixedly connected by the joint bearing, and the other end can realize rotational movement with other axial objects.

[0057] An adjustment slot 126 is defined on the first transmission rod 121 , and an adjustment fixing structure 127 is provided between the first transmission rod 121 and the first rotating connector 124 . The adjustment fixing structure 127 is used to adjust the first rotating connector 124 to be installed at any position in the adjustment slot 126 .

[0058] See Figure 4 As shown, in order to be able to adjust the distance of the reciprocating movement of the connecting rod 122, and thus indirectly achieve the adjustment of the rotation angle of the rotating shaft 130, the position of the first rotating connecting member 124 in the adjusting groove 126 can be adjusted by adjusting the fixed structure 127. According to the accompanying drawings, it can be understood that when the rotation center of the first rotating connecting member 124 is closer to the output shaft of the driving member 110, the smaller the amplitude of the reciprocating movement of the connecting rod 122, the smaller the corresponding rotation angle of the rotating shaft 130, and the lower the height that the roller structure 150 can reach; conversely, the higher the height that the roller structure 150 can reach.

[0059] The adjusting and fixing structure 127 includes a connecting shaft 1271 passing through the adjusting slot 126 . The connecting shaft 1271 is rotatably connected to the first rotating connector 124 . Fasteners 1272 are installed at both ends of the connecting shaft 1271 .

[0060] Continue reading Figure 4As shown, the connecting shaft 1271 serves as the rotation axis of the first rotating connection member 124. When the connecting rod 122 moves back and forth, the first rotating connection member 124 can rotate around the connecting shaft 1271. The connecting shaft 1271 passes through the first rotating connection member 124 and the adjustment slot 126 at the same time. After the connecting shaft 1271 is adjusted to a suitable position in the adjustment slot 126, the connecting shaft 1271 can be fixed to the first transmission rod 121 by the fasteners 1272 at both ends of the connecting shaft 1271, thereby maintaining the distance between the rotation center of the first rotating connection member 124 and the output shaft of the driving member 110, thereby determining the angle of rotation of the rotating shaft 130. In practice, other fixed structures can also be used to fix the rotation point of the first rotating connection member 124 at different positions of the adjustment slot 126.

[0061] In this embodiment, the fastener 1272 can be a nut. Accordingly, the outer surfaces of both ends of the connecting shaft 1271 need to be provided with corresponding threads to achieve connection with the nut.

[0062] There are N mounting rods 140 , and N≧1. When N≧2, adjacent mounting rods 140 are spaced apart.

[0063] The roller structure 150 includes a mounting shaft 151 rotatably mounted on the mounting rod 140 , and M rolling wheels 152 are rotatably mounted on the mounting shaft 151 , satisfying: M ≥ 1.

[0064] See Figure 1 and Figure 3 As shown, the mounting rod 140 is fixedly mounted on the outer surface of the rotating shaft 130. In this embodiment, there are two mounting rods 140, that is, the above parameter N is 2. The spacing between the two mounting rods 140 can be adjusted according to the size and width of the tiles, etc. The specific spacing is not limited here.

[0065] Continue reading Figure 1 and Figure 3 As shown, when the mounting rod 140 rotates upward to lift the tiles, in order to prevent the tiles from directly contacting the end of the mounting rod 140 and causing scratches, a roller structure 150 is installed at the end of the mounting rod 140, and the roller structure 150 rolls with the tiles. Specifically, a rolling wheel 152 is provided on the mounting shaft 151 installed at the end of the mounting rod 140, and the rolling wheel 152 is rotatably installed on the mounting shaft 151, so that when the rolling wheel 152 contacts the tiles, the rolling wheel 152 can roll, reducing the friction resistance between the rolling wheel 152 and the tiles, so that the tiles can be transported more conveniently.

[0066] In this embodiment, a rolling wheel 152 is rotatably mounted at both ends of the mounting shaft 151, that is, M in the above is 2, and the distance between the two rolling wheels 152 can be adjusted according to actual needs, which is not specifically limited here.

[0067] The present application also provides a conveying device, comprising any of the above-mentioned conveying line switching devices 100, a first conveying line 200, and a second conveying line 300.

[0068] The first conveyor line 200 includes a first mounting frame 210, on which a plurality of first conveyor belts 220 are installed at intervals, and the conveyor line switching device 100 is installed on the first mounting frame 210. The second conveyor line 300 is located in the first preset direction of the first conveyor line 200, and the second conveyor line 300 includes a second mounting frame 310, on which a plurality of second conveyor belts 320 are installed at intervals.

[0069] See Figure 5 and Figure 6 As shown, in this embodiment, two first conveyor belts 220 spaced apart from each other are installed on the first mounting frame 210, and two second conveyor belts 320 spaced apart from each other are also installed on the corresponding second mounting frame 310. It should be noted that the first conveyor belt 220 and the second conveyor belt 320 are both driven by a motor (not shown) to realize transmission; the conveyor line switching device 100 is installed on the first mounting frame 210, and the rotation of the rotating shaft 130 can drive the mounting rod 140 and the roller structure 150 to pass through the gap between the two first conveyor belts 220, so that the roller structure 150 is located above the conveying plane of the first conveyor belt 220, thereby realizing support and guidance of the tiles on the first conveyor belt 220.

[0070] See Figure 5 、 Figure 6 as well as Figure 7 As shown, in the initial state, the tiles are conveyed on the first conveyor belt 220. When the tiles need to be conveyed from the first conveyor belt 220 to the second conveyor belt 320 and the tiles are conveyed to the position of the roller structure 150, the driving member 110 is started, and the power from the driving member 110 is converted into the rotational force of the rotating shaft 130 through the connecting rod structure 120, so that the mounting rod 140 and the roller structure 150 can be driven to rotate. The roller structure 150 rotates upward and contacts the bottom surface of the tiles. As the roller structure 150 continues to rotate, it drives the tiles to lift upward. The friction between the first conveyor belt 220 and the tiles drives the tiles to continue to move forward until the bottom of the tiles contact the surface of the second conveyor belt 320. As the second conveyor belt 320 rotates, the friction between the second conveyor belt 320 and the tiles drives the tiles to be conveyed to the second conveyor belt 320, completing the action of conveying the tiles from the first conveyor belt 220 to the second conveyor belt 320.

[0071] An included angle α is formed between the first conveyor belt 220 and the second conveyor belt 320 and satisfies the following: 20°≤α≤60°.

[0072] Continue reading Figure 5 and Figure 6 As shown, in order to enable the tiles on the first conveyor belt 220 to be smoothly transported to the second conveyor belt 320, the first conveyor belt 220 can be tilted at a certain angle, so that the contact area between the second conveyor belt 320 and the tiles is larger, and the tiles can be more easily transported to the second conveyor belt 320. For example, the angle α between the first conveyor belt 220 and the second conveyor belt 320 can be: 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. In this embodiment, the angle between the first conveyor belt 220 and the second conveyor belt 320 is 45°. In practice, it can be selected according to needs, and the specific angle is not limited here.

[0073] Furthermore, the first conveyor belt 220 is in a horizontal state and the second conveyor belt 320 is in an inclined state. It can be understood that the angle between the second conveyor belt 320 and the horizontal plane is the same as the angle between the second conveyor belt 320 and the first conveyor belt 220.
