Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically to a conveyor for feeding shaft-type parts to multiple machine tools. Background Technology

[0002] Utilizing automated production lines can not only greatly enhance a company's competitiveness but also bring significant benefits. As the level of automation in manufacturing companies continues to improve, the market for automated production lines is growing larger and larger.

[0003] The utility model discloses a shaft parts feeder with the publication number CN210392839U. The feeder uses a crank and guide rod in the conveying mechanism to achieve continuous feeding. The guide rod rotates with the motor and moves in the first and second limit grooves in the limited trajectory to lift the shaft parts and move forward and then down. Individual parts will roll into the positioning mechanism and be accurately positioned, which is convenient for gripping and feeding. The structure is simple, the operation is stable, and the degree of automation is high.

[0004] In addition to the advantages mentioned above, this utility model patent still has some shortcomings. Firstly, the shaft feeder can only feed one machine tool at a time. In today's era of widespread automated production, the feeder is difficult to meet the production needs of the factory, and the feeding efficiency is slow, resulting in slow parts production progress. Utility Model Content

[0018] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] Please see Figure 1-2 This utility model provides a technical solution:

[0020] The system includes a conveyor belt 1. On one side of the conveyor belt 1, a first lifting device 2, a second lifting device 3, and a third lifting device 4 are sequentially arranged. The spacing between the first lifting device 2, the second lifting device 3, and the third lifting device 4 is the same. A number of supporting feet 5 are fixedly connected to the bottom of the conveyor belt 1. A speed-regulating motor 6 is installed on one side of the middle of the conveyor belt 1. A PLC controller 10 is installed on the other side of the middle of the conveyor belt 1. A number of three processing machine tools 8 are arranged on one side of the conveyor belt 1. A mechanical gripper 9 is provided on the top of the processing machine tool 8. There are three mechanical grippers 9, and their positions correspond to the first lifting device 2, the second lifting device 3, and the third lifting device 4. A conveying groove 11 is opened on the top of the conveyor belt 1. A number of shaft parts 7 are placed in the inner cavity of the conveying groove 11.

[0021] In this embodiment, the first lifting device 2 includes a mounting frame 21. A claw cylinder 22 is provided on the top of one side of the inner wall of the mounting frame 21. A claw 23 is connected to the bottom of the claw cylinder 22. A blocking cylinder 24 is movably connected to the bottom of the other side of the inner wall of the mounting frame 21. A blocking block 25 is connected to the bottom side of the blocking cylinder 24.

[0022] In this embodiment, please refer to Figure 2-3 An infrared detector 27 is provided on one side of the blocking block 25, an infrared detector 28 is provided on one side of the gripper 23, and an infrared detector 29 is provided on the bottom side of the mounting bracket 21. This is to facilitate the detection of the shaft part 7 by the infrared detector 27 after it is blocked by the blocking block 25, so that the PLC controller 10 receives a signal and drives the gripper cylinder 22 to make the gripper 23 grab the shaft part 7. The gripping is successfully detected by the infrared detector 29, so the PLC controller 10 controls the gripper cylinder 22 to drive the gripper 23 to move the shaft part 7 upward. The infrared detector 29 detects whether there is a shaft part 7 at the bottom of the blocking block 25. If there is a shaft part 7, the blocking cylinder 24 will not drive the blocking block 25 to move downward, thus preventing the blocking block 25 from pressing down on the shaft part 7. The infrared detectors 27, 28, and 29 used in this device are of model FT-H20.

[0023] In this embodiment, please refer to Figure 2-3The bottom cavity of the mounting frame 21 has a movable groove 26. The bottom of the blocking cylinder 24 is movably connected to the inner wall of the movable groove 26. The blocking block 25 is located in the inner cavity of the conveying groove 11, which facilitates the adjustment of the position of the blocking cylinder 24 so that it can move along the movable groove 26, thereby allowing the blocking block 25 to move along the inner cavity of the conveying groove 11 and adjust its blocking position. By adjusting the position of the blocking block 25, shaft parts 7 of different lengths can be successfully gripped by the claw 23. At the same time, since the blocking block 25 is located in the inner cavity of the conveying groove 11, it can block the shaft parts 7. By moving the blocking block 25 upward, it no longer blocks the shaft parts 7, allowing the shaft parts 7 to continue to be conveyed backward.

[0024] In this embodiment, please refer to Figure 3 The PLC controller 10 is electrically connected to infrared detector 27, infrared detector 28, and infrared detector 29. The PLC controller 10 is also electrically connected to the gripper cylinder 22 and the blocking cylinder 24 via a solenoid valve. This facilitates the detection of the location of the shaft part 7 by infrared detectors 27, 28, and 29, and allows the PLC controller 10 to control the gripper cylinder 22 and the gripper 23 to grasp or release the shaft part 7.

[0025] The working principle of this utility model is as follows: A shaft-type part 7 is placed into the feeding end of the conveyor belt 1. When the shaft-type part 7 is transported to the mounting frame 21 via the conveyor trough 11, a blocking cylinder 24 drives a blocking block 25 to move downwards. When the shaft-type part 7 reaches the blocking block 25, it is blocked. After the shaft-type part 7 is blocked, the first infrared detector 27 detects the blocked object and sends an electrical signal to the PLC controller 10. The PLC controller 10 activates the gripper cylinder 22 via a solenoid valve, which drives the gripper 23 to move downwards and grab the shaft-type part 7. After the second infrared detector 28 detects that the gripper 23 has successfully grabbed the shaft-type part 7, it continues to send an electrical signal to the PLC controller 10. The PLC controller 10 then activates the gripper cylinder 22 to drive the gripper 23 to move upwards, thereby causing the gripper 23 to move upwards. The PLC controller 10 also controls the blocking cylinder 24 to drive the blocking block 25 upwards. At this time, subsequent shaft-type parts 7 are transported along with the conveyor trough 11. When the shaft part 7 is conveyed to the first lifting device 2, it is not blocked and continues to be conveyed forward. When it is conveyed to the third lifting device 4, it is grabbed again. According to the above principle, the shaft part 7 is continuously conveyed through the inner cavity of the conveying groove 11. First, the second lifting device 3 grabs the shaft part 7. After the grab is successful, the subsequent shaft part 7 can continue to be conveyed through the second lifting device 3. When it moves to the first lifting device 2, it is grabbed by the first lifting device 2. After the first lifting device 2 finishes grabbing, the subsequent shaft part 7 is grabbed by the third lifting device 4. When the shaft part 7 is grabbed by the lifting device, the mechanical gripper 9 takes the shaft part 7 grabbed by the bottom of the claw 23 and conveys it to the processing machine tool 8 for processing. When the second infrared detector 28 detects that the shaft part 7 has been taken away, it generates an electrical signal to send to the PLC controller 10. The PLC controller 10 controls the blocking cylinder 24 to drive the blocking block 25 to move downward, to continue to intercept the shaft part 7 that is subsequently conveyed, and to grab the shaft part 7 again.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
