Detection device for pipe fitting production

Abstract

The utility model discloses a detection device for pipe fitting production, which comprises a rack, a conveying line for conveying a mold core is arranged on the rack, and a detection device for detecting whether the mold core is sleeved with a pipe fitting is arranged on a detection station of the rack. By arranging the detection device, when the conveying line drives the mold core to move to the detection station, the detection device can detect whether the mold core is sleeved with the pipe fitting or not, so that the situation that the production line is shut down due to the fact that the empty mold core without the pipe fitting is moved to demolding equipment by a mechanical arm is avoided, normal operation of the production line can be effectively guaranteed, and the probability of shutdown maintenance is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting injection molding production, in particular to a detection device used for pipe fitting production. Background Art

[0002] Prior art, such as the Chinese utility model patent publication number CN220313992U, discloses a multi-directional manipulator. This prior art uses the manipulator to remove a mold core after injection molding from a transfer center and place the mold core, fitted with a pipe fitting, into a core demolding device for demolding, thereby separating the mold core from the pipe fitting.

[0003] Based on the above, in actual production, due to various factors, unmolded cores may appear in the transfer center. Because the pipe fittings produced are electrofusion pipe fittings, wire needs to be wrapped around the core surface before injection. When the unmolded core with wire is grasped by the robot and removed from the core by the mold removal equipment, the wire will scatter, causing the equipment to stop for encapsulation and maintenance, requiring the entire production line to be shut down for maintenance, affecting production efficiency and requiring further improvement. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a detection device for pipe production.

[0005] A detection device for pipe production designed for this purpose includes a frame, a conveying line for conveying mold cores is provided on the frame, and a detection device for detecting whether a pipe is mounted on the mold core is provided at a detection station of the frame.

[0006] Preferably, the detection device comprises two spaced-apart opposing beam sensors;

[0007] Of the two through-beam sensors, one is used to transmit signals and the other is used to receive signals. When a pipe is provided on the core sleeve at the detection station, the pipe blocks the signal transmission of the two through-beam sensors.

[0008] Preferably, a detection element for detecting the mold core is provided on the detection station of the frame.

[0009] Preferably, the detection element is a proximity switch.

[0010] Preferably, the two through-beam sensors are spaced apart from each other.

[0011] Preferably, the through-beam sensor is a fiber optic sensor.

[0012] Preferably, the rack is provided with a pick-up and placement port, and the pick-up and placement port is spaced apart from the detection device in front and behind.

[0013] Compared to the prior art, the present invention features a detection device at the inspection station on the frame for detecting whether a pipe fitting is fitted onto the mold core. This device, when the conveyor line drives the mold core to the inspection station, can detect whether the mold core is fitted with a pipe fitting. This prevents an empty mold core without a pipe fitting from being moved to the demoulding equipment by the robot, which could cause the production line to shut down. This effectively ensures the normal operation of the production line and reduces the likelihood of downtime for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See also Figures 1-4 A detection device for pipe fitting production includes a frame 10, a conveying line 20 for conveying a mold core 40 is provided on the frame 10, and a detection device 60 for detecting whether a pipe fitting 50 is mounted on the mold core 40 is provided on the detection station of the frame 10.

[0020] The utility model is provided with a detection device. When the conveyor line drives the mold core to move to the detection station, the detection device can detect whether the mold core is covered with a pipe fitting, so as to avoid the empty mold core without a pipe fitting being moved to the demoulding equipment by the robot arm and causing the production line to stop. It can effectively ensure the normal operation of the production line and reduce the chance of shutdown for maintenance.

[0021] See also Figure 2 , the detection device 60 includes two spaced-apart through-beam sensors 610;

[0022] Of the two through-beam sensors 610 , one through-beam sensor 610 is used to transmit signals, and the other through-beam sensor 610 is used to receive signals; when the mold core 40 located at the detection station is provided with a pipe fitting 50 , the pipe fitting 50 blocks the signal transmission of the two through-beam sensors 610 .

[0023] See also Figure 2 and Figure 4 Because the thickness of a single mold core 40 is different from that of a mold core fitted with a tube 50, when a mold core 40 carrying a tube 50 moves to the inspection station, the tube 50 blocks the signal transmission from the two through-beam sensors 610. When signal transmission is interrupted, the system determines that the mold core 40 contains a tube 50. If the mold core 40 is already at the inspection station, the two through-beam sensors 610 can still transmit signals, and the mold core 40 is determined to be free of the tube 50. This detection method effectively prevents mold cores 40 without tubes 50 from entering the demolding equipment.

[0024] See also Figure 2 The inspection station of the frame 10 is provided with a detection element 70 for detecting the mold core 40. The detection element 70 is used to detect whether the mold core 40 is located in the inspection station while being driven by the conveyor line 20. The detection element 70 is used to assist the through-beam sensor 610 in performing detection. The detection element 70 is used to determine whether the mold core 40 is located in the inspection station, and the through-beam sensor 610 is used to determine whether the mold core 40 is located in the inspection station.

[0025] In the present invention, the detection element 70 is a proximity switch.

[0026] In the present invention, two through-beam sensors 610 are arranged vertically and spaced apart.

[0027] In the present invention, the through-beam sensor 610 is a fiber optic sensor.

[0028] See also Figure 1 The rack 10 is provided with a pick-up and placement port 100 , and the pick-up and placement port 100 is spaced apart from the detection device 60 in front and back.

[0029] In the present invention, the conveyor line 20 adopts an existing chain-type conveyor line, and a fixing seat 30 for fixing the mold core 40 is provided on the conveyor line 20 .
