Description

Technical Field

[0001] This utility model belongs to the technical field of automatic packaging of PPR pipe fittings, specifically relating to a pipe fitting conveying, unloading detection and rejection device. Background Technology

[0002] In the automated packaging production process for anti-counterfeiting and anti-counterfeiting of some PPR pipe fittings, the PPR pipe fittings are conveyed by a centrifugal feeding conveyor, and then accelerated by an accelerator belt conveyor to increase the spacing between the pipe fittings before subsequent laser engraving of anti-counterfeiting QR codes and corresponding packaging processes. To ensure the consistency and aesthetics of the laser engraving, the pipe fittings need to be conveyed upright with a consistent orientation and front-to-back position into the laser engraving area. However, during the centrifugal feeding conveyor process, pipe fittings are inevitably pushed over and conveyed in a manner that can cause jamming. Furthermore, the QR codes on overturned pipe fittings are often blurred and unreadable after laser engraving, requiring them to be scrapped. Therefore, a device is needed to ensure the consistent orientation and front-to-back position of the pipe fittings during conveying and to promptly remove overturned pipe fittings from the laser engraving area.

[0007] Furthermore, a second guide limiting rod for guiding and limiting the pipe fitting is provided above one side of the inspection belt conveyor. The first guide limiting rod and the second guide limiting rod are at the same height and their adjacent ends are coaxial.

[0008] Furthermore, the steering adjustment rod, the first guide limit rod, and the second guide limit rod are respectively mounted on the pipe conveying mechanism through at least two sets of adjustable mounting brackets.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

The pipe fitting conveying mechanism 1 is fixed on the general mounting plate 101. The pipe fitting conveying mechanism 1 includes an accelerating belt conveyor 11, a detection belt conveyor 12, and an alloy connecting strip 13 for connecting the accelerating belt conveyor 11 and the detection belt conveyor 12 to achieve a smooth transition. The accelerating belt conveyor 11 and the detection belt conveyor 12 are respectively assembled from a general frame, a conveying motor, a conveying belt, and rollers. The alloy connecting strip 13 is welded from perforated stainless steel sheets and wear-resistant alloy strips. The alloy connecting strip 13 can ensure that the pipe fittings being conveyed normally vertically can smoothly transition from the accelerating belt conveyor 11 to the detection belt conveyor 12 without tipping over, thus improving the stability of the device operation.The rejection slide 5 is installed at an angle downwards on one side of the inspection belt conveyor 12 and is fixed to the inspection belt conveyor 12 by four hexagon socket screws. The rejection slide 5 is made of thickened stainless steel plate cut, welded and drilled. The lower end of the rejection slide 5 faces the rejection product receiving frame 10. The rejection air nozzle 4 is fixed on the overall mounting plate 101 and extends to the top of the inspection belt conveyor 12. The rejection air nozzle 4 is located on the opposite side of the rejection slide 5. When the rejection air nozzle 4 is working, compressed gas will be introduced into it to blow out the pipe. The signal transmitting mechanism 2 includes a transmitter mounting frame 21 fixed above the rejection slide 5, a material receiving sensor transmitter 22 located below the transmitter mounting frame 21, and a transmitter mounted on the transmitter mounting frame 21. The material discharge sensor transmitter 23 and the signal receiving mechanism 3 are installed on the other side of the detection belt conveyor 12 and are symmetrically arranged with the signal transmitting mechanism 2. The signal receiving mechanism 3 includes a receiver mounting bracket 31 fixed on the detection belt conveyor 12, an incoming material sensor receiver 32 located at the lower part of the receiver mounting bracket 31 for receiving the signal from the incoming material sensor transmitter 22 to determine whether there is a pipe being transported, and a material discharge sensor receiver 33 located at the upper part of the receiver mounting bracket 31 for receiving the signal from the material discharge sensor transmitter 23 to determine whether the transported pipe is a material discharge pipe. A steering adjustment rod 6 is provided above one side of the acceleration belt conveyor 11 to drive the pipe to rotate and ensure that the pipe is oriented in a uniform direction, and a first guide limiter for guiding and limiting the pipe. Positioning rod 7, the first guide limiting rod 7 is located above the steering adjustment rod 6, and a second guide limiting rod 8 for guiding and limiting the pipe fitting is provided above one side of the detection belt conveyor 12. The first guide limiting rod 7 and the second guide limiting rod 8 are at the same height and their adjacent ends are coaxial. The steering adjustment rod 6, the first guide limiting rod 7 and the second guide limiting rod 8 are respectively mounted on the pipe fitting conveying mechanism 1 through at least two sets of adjustable mounting brackets 9. Each set of adjustable mounting brackets 9 includes a clamp 91, a vertical adjusting rod 92, a horizontal adjusting rod 93 and a cross clamp 94. The clamp 91 is fixed to the side of the pipe fitting conveying mechanism 1, the cross clamp 94 is located above the clamp 91, and one end of the vertical adjusting rod 92 is connected to the clamp 91. One end of the horizontal adjusting rod 92 is adjustablely connected to the cross clamp 94, and the other end is fixedly connected to the steering adjusting rod 6, the first guide limiting rod 7 or the second guide limiting rod 8. By adjusting the connection position between the vertical adjusting rod 92 and the cross clamp 94, the height of the steering adjusting rod 6, the first guide limiting rod 7 or the second guide limiting rod 8 can be adjusted. By adjusting the connection position between the horizontal adjusting rod 93 and the cross clamp 94, the position or tilt angle of the steering adjusting rod 6, the first guide limiting rod 7 or the second guide limiting rod 8 on the pipe conveying mechanism 1 can be adjusted. The two ends of the steering adjusting rod 6 and the first guide limiting rod 7 are bent structures.

[0016] The working method of a pipe fitting conveying and unloading detection and rejection device includes the following steps: Install this device on the right side of the centrifugal material distribution conveyor, so that the left side of the accelerating belt conveyor 11 is connected to the outlet of the centrifugal material distribution conveyor. Start the entire anti-counterfeiting and anti-counterfeiting automatic packaging line and this device. The centrifugal material distribution conveyor will continuously centrifuge and distribute the pipe products, which will enter the accelerating belt conveyor 11 in an upright position. Some pipe products will be squeezed down. The accelerating belt conveyor 11 will accelerate the conveying of the pipes that are close together to separate them. During the process of conveying the upright pipes to the right, their bottoms will rub against the steering adjustment rod 6, so their heads can rotate counterclockwise until their heads touch the first guide limit rod 7. Then, these pipes with the same orientation after the steering adjustment will continue to be conveyed to the right along the first guide limit rod 7. After the smooth transition through the alloy connecting strip 13, these upright pipes with the same orientation will enter the detection belt conveyor 12 and be driven to the right by the detection belt conveyor 12. During this period, the second guide limit rod 8 will provide guidance and limit to keep them in their original orientation.

[0017] When these upright, uniformly conveyed pipes enter the detection area, because the pipes are upright, they obstruct the sensing devices. The signal from the incoming material sensor transmitter 22 cannot be received by the incoming material sensor receiver 32, and the signal from the outgoing material sensor transmitter 23 cannot be received by the outgoing material sensor receiver 33. The system determines that the pipe is a normally upright conveyed pipe, and the rejection nozzle 4 does not activate. The pipe continues to be conveyed to the right into the laser engraving machine's engraving range for anti-counterfeiting QR code engraving, and finally flows into subsequent packaging. If the signal from the incoming material sensor transmitter 22 cannot be received by the incoming material sensor receiver 32, but the signal from the outgoing material sensor transmitter 23 is received by the outgoing material sensor receiver 33, the system determines that the pipe is an outgoing pipe. Compressed air is introduced into the bottom of the rejection nozzle 4 and sprayed from the nozzle head to blow the outgoing pipe forward into the rejection chute 5, and it falls into the rejection product receiving frame 10 along the rejection chute 5. The device continues to perform pipe product conveying, orientation adjustment, guide limit, detection judgment, and rejection execution actions, repeating this process.
