Description

Technical Field

[0001] This application is applied to the field of automated conveying, and specifically relates to an inclined conveying device. Background Technology

[0002] In various fields of automated conveying, after the conveyor line transports the load to the predetermined position, it is necessary to tilt the load at a certain angle to facilitate processing by operators or robotic arms. Existing technologies often use lifting mechanisms to lift and tilt the load, which requires additional complex mechanisms and increases costs. In addition, the load may fall off during the resetting process after tilting. Summary of the Invention

[0003] In view of the above reasons, this application discloses an inclined conveying device, including a conveyor line, a base, a drive mechanism and a limiting mechanism. A first side of the conveyor line in the conveying direction is hinged to the base. The drive mechanism is placed on the base and drives a second side of the conveyor line in the conveying direction to rotate around the first side. The first side and the second side are opposite sides. The limiting mechanism is disposed on the base and acts on the first side of the conveyor line. The limiting mechanism limits the inclination angle of the conveying plane of the conveyor line.

[0004] Preferably, a bushing is provided on the lower part of the first side of the conveyor line, and a bearing seat is provided at the opposite position of the base. The drive shaft is fixedly mounted on the bushing and sleeved on the bearing seat. A limiting plate is provided on one side of the bushing, and a limiting pin is provided on the base at the corresponding position of the limiting plate. When the conveyor line is in a horizontal position, the limiting plate and the limiting pin are spaced apart. When the conveyor line is tilted to a preset angle by the drive mechanism, the limiting plate and the limiting pin abut against each other, restricting the conveyor line from continuing to rotate.

[0005] Preferably, the limiting pin is connected to the base via a mounting block, the limiting pin passes through the mounting block, and the position of its head relative to the mounting block is adjustable.

[0006] Preferably, the driving mechanism includes a locking cylinder, the fixed end of which is hinged to the base, and the free end of which is hinged to the lower end of the second side of the conveyor line.

[0007] Preferably, it further includes a buffer mechanism, which includes a buffer with its head end facing upward through the mounting block and abutting against the limiting plate.

[0008] Preferably, it further includes a detection mechanism, which includes a first proximity switch, a second proximity switch, and a sensing element. The sensing element is disposed at one end of the rotating shaft and rotates synchronously with the rotating shaft. The first proximity switch and the second proximity switch are disposed on the base via a mounting plate. The first proximity switch and the second proximity switch are arranged vertically to detect the position of the sensing element and generate a detection signal. The detection signal is sent to the PLC.

[0009] Preferably, it also includes a maintenance mechanism, which includes a positioning plate, a pin seat, and a pin. The positioning plate is fixedly sleeved on the drive shaft and rotates synchronously with the drive shaft. The positioning plate has several circumferentially spaced positioning holes. The pin seat is disposed on the base. The pin can pass through the reserved hole of the pin seat and be placed in the positioning hole to limit the rotation of the drive shaft.

[0010] Preferably, it also includes a vertical stopper, which is disposed on the conveyor line and acts on the load conveyed by the conveyor line.

[0011] Preferably, the conveyor line is a roller conveyor.

[0012] The advantages of this application are that it uses a drive mechanism to tilt the conveyor line and the load at the same time, and uses a limit mechanism to limit the tilt angle to prevent over-tilting. It also adds a buffer mechanism to achieve flexible start and stop, and improves the safety of the device through a maintenance mechanism.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 3 As shown, the load 2 is placed on the conveyor line 1, which can run along the conveying direction. The base 3 is placed below the conveyor line 1. The base 3 is a profile combination bracket used to fix it to the ground or to other fixed surfaces. The first side of the conveyor line 1 in the conveying direction is hinged to the base 3. The drive mechanism is set on the base and acts on the second side of the conveyor line 1 in the conveying direction, causing the second side of the conveyor line 1 in the conveying direction to rotate around the first side of the conveyor line 1 in the conveying direction. The first side and the second side are opposite sides. The limiting mechanism is set on the base 3 and acts on the first side of the conveyor line 1 to limit the tilt angle of the conveying plane of the conveyor line 1.

[0025] like Figure 1 As shown, the conveyor line 1 is initially in a horizontal state, and the load 2 moves to a predetermined position under the drive of the conveyor line 1, as follows. Figure 2As shown, the drive mechanism drives the second side of the conveyor line 1 to rotate upward around the first side. The rotation angle is limited by the limiting mechanism, and the conveyor line 1 is limited to a preset rotation angle. The specific rotation angle is determined according to the actual working conditions. The limiting mechanism is adjusted according to the actual working conditions. In this application, 10 degrees is selected. At this time, the load 2 is in an inclined state and is limited by the edge profile of the conveyor line 1 so that it will not slip off the conveyor line 1. The operator or robot can perform processing operations on the load 2. After the processing operation is completed, the drive mechanism drives the second side of the conveyor line 1 to rotate downward around the first side. The conveyor line 1 returns to the horizontal position, and the load 2 continues to run.

[0026] like Figures 1 to 5 As shown, a downward-facing bushing 4 is provided on the lower part of the first side of the conveyor line 1. A bearing seat 5 is provided on the upper part of the first side of the base 3 at the opposite position. A drive shaft 6 is provided inside the bushing 4. The length direction of the drive shaft 6 is the conveying direction of the conveyor line 1. The drive shaft 6 is keyed to the bushing 4. The two ends of the drive shaft 6 are respectively inserted into the bearing seats 5 on the corresponding sides. Through the bushing 4, the drive shaft 6 and the bearing seats 5, the first side of the conveyor line 1 is hinged to the base 3, and the conveyor line 1 can rotate around the base 3. A limiting plate 7 is provided on one side of the bushing 4. The limiting plate 7 is a flat metal plate. A limiting pin 8 is provided at the base 3 below the limiting plate 7. When the conveyor line 1 is in a horizontal position, the limiting pin 8 is placed below the limiting plate 7 and does not contact the limiting plate 7. The limiting plate 7 is in a horizontal state. When the conveyor line 1 is in an inclined state, the conveyor line 1 drives the bushing 4 to rotate synchronously with the limiting plate 7. After rotating to a preset angle, the limiting plate 7 abuts against the limiting pin 8, and the limiting plate 7 cannot rotate further, that is, the conveyor line 1 is restricted from continuing to rotate.

[0027] like Figures 1 to 5 As shown, the limiting pin 8 is set on the upper end of the first side of the base 3 through the mounting block 9. The limiting pin 8 passes through the mounting block 9. The limiting pin 8 may be provided with external threads. The mounting block 9 has a corresponding screw hole. The position of the head end of the limiting pin 8 relative to the mounting block 9 can be adjusted by rotation or other means. That is, the distance of the limiting pin 8 relative to the limiting plate 7 can be adjusted. By changing the position of the head end of the limiting pin 8, the limiting angle of rotation of the conveyor line 1 can be adjusted.

[0028] like Figure 1 As shown, the driving mechanism is a locking cylinder 10. The fixed end of the locking cylinder 10 is hinged to the base 3, and the free end of the locking cylinder 10 is hinged to the lower end of the second side of the conveyor line 1. The locking cylinder 10 is set at an angle, which can effectively save the height space it occupies.

[0029] like Figures 1 to 5As shown, the head end of the buffer 11 is vertically inserted through the mounting block 9, and the head end of the buffer 11 is in contact with the limiting plate 7. During the process of the limiting plate 7 rotating from horizontal to inclined, the limiting plate 7 presses the head end of the buffer 11 downward. The buffer 11 buffers the rotation process of the limiting plate 7, realizes flexible rotation, and plays a buffering role.

[0030] like Figures 1 to 5 As shown, the detection mechanism includes a first proximity switch 12, a second proximity switch 13, and a sensing plate 14. The sensing plate 14 has a length, and one end of the sensing plate 14 is set at one end of the transmission shaft 6 and can rotate synchronously with the transmission shaft 6. The first proximity switch 12 and the second proximity switch 13 are set on the base 3 through the mounting plate 15. The first proximity switch 12 is located above the second proximity switch 13. The other end of the sensing plate 14 will pass through the first proximity switch 12 and the second proximity switch 13 respectively during rotation. When the conveyor line 1 is in a horizontal position, the sensing plate 14 is located at the position of the second proximity switch 13 and generates a corresponding control signal. When the conveyor line 1 is in an inclined position, the sensing plate 14 is located at the position of the first proximity switch 12 and generates a corresponding detection signal. The detection signal can be converted into light information or sound information to prompt the operator on the status. At the same time, the detection signal will be sent to the PLC (programmable controller) to synchronously feedback the current status of the conveyor line 1.

[0031] like Figures 1 to 2 As shown, the vertical stopper 16 is installed on the conveyor line 1 via the connecting plate 17. The vertical stopper 16 extends and retracts to block the load 2 on the conveyor line 1. When the load 2 is conveyed to the preset position on the conveyor line 1, the vertical stopper 16 extends to block the load 2. Then, the locking cylinder 10 pushes the conveyor line 1 to tilt. After the load 2 is processed, the locking cylinder 10 drives the conveyor line 1 to reset, the vertical stopper 16 retracts, and the load 2 can continue to run to the subsequent stroke. By setting the vertical stopper 16, the load 2 can be blocked at the preset position while the conveyor line 1 is running continuously, without the need to frequently control the start and stop of the conveyor line 1.

[0032] like Figure 3 and Figure 6As shown, the maintenance mechanism includes a positioning plate 18, a pin seat 19, and a pin 20. The positioning plate 18 is located at one end of the drive shaft 6 and rotates synchronously with the drive shaft 6. The positioning plate 18 has several circumferentially spaced positioning holes 1801, which are round holes. The pin seat 19 is located on the base near the positioning plate. The pin seat 19 has a through reserved hole, through which the pin 20 can pass and be placed in the positioning hole 1801 of the positioning plate 18, thereby restricting the rotation of the drive shaft 6 and playing a mechanical blocking role. During maintenance, it can prevent the device from suddenly starting and causing injury to the operator. There can be two positioning holes 1801, corresponding to the horizontal position and the inclined position of the conveyor line 1, respectively, so that maintenance can be carried out safely in both states.

[0033] In this application, the conveyor line 1 can be a conventional conveying mechanism, such as a belt conveyor, chain conveyor, sheet belt conveyor, etc. In this embodiment, the conveyor line adopts a roller conveyor.
