Description

Technical Field

[0001] This utility model relates to the technical field of PPR pipe fitting production and packaging, specifically to a chain plate conveyor orientation adjustment device for female bend pipe fittings. Background Technology

[0002] In the existing automated packaging process, female bend pipe fittings are picked up by a robot and placed on a conveyor belt, where they are positioned and limited by positioning pins. The conveyor belt then moves the female bend pipe fittings for rear-end laser marking of QR codes. However, because the orientation of the female bend pipe fittings cannot be guaranteed to be uniform when placed by the robot, marking deformation and inconsistent marking positions easily occur during the rear-end laser marking process, affecting product quality. Therefore, a device is needed to adjust and unify the orientation of the female bend pipe fittings before they are conveyed and marked. Utility Model Content

[0026] 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 to the scope described herein.

[0027] Please refer to Figure 1 A device for adjusting the orientation of a concave bend pipe fitting conveyor chain includes a concave bend conveyor 2, a set of carriers 9 on the concave bend conveyor 2, the carriers 9 being evenly distributed on the concave bend conveyor 2 and fixedly connected to the conveyor chain of the concave bend conveyor 2, and an orientation adjustment mechanism 1 on one side of the concave bend conveyor 2, which can automatically adjust the orientation of the concave bend pipe fitting 3 conveyed on the concave bend conveyor 2.

[0028] Please refer to Figure 2-6 The orientation adjustment mechanism 1 includes two symmetrically arranged orientation adjustment mechanism overall fixing frames 4, which are fixed to the chain conveyor 2. One of the orientation adjustment mechanism overall fixing frames 4 is equipped with an adjustment component. The orientation adjustment mechanism overall fixing frame 4 includes a clamp 41, a fixing rod 43 on the clamp 41, and a clamp 42 on the fixing rod 43. The clamp 42 is detachably connected to the fixing rod 43 and the clamp 41. A guide limit rod 6 is engaged between the two clamps 42 and fixed with bolts. By loosening the clamping screws on the clamp 41 and the clamp 42, the vertical height and horizontal position of the orientation adjustment mechanism overall fixing frame 4 can be adjusted.

[0029] The adjustment assembly includes a movable slide rail fixing bracket 22, which is made of thickened steel plate by cutting, drilling, and grinding. The movable slide rail fixing bracket 22 is fitted onto the fixing rod of the overall fixing bracket 4 of the orientation adjustment mechanism and clamped and fixed by locking it with an internal hex screw. A movable slide rail 23 is fixedly mounted on the movable slide rail fixing bracket 22. An adjusting bolt abutment plate 21 is fixedly mounted on the upper side of the movable slide rail 23. The adjusting bolt abutment plate 21 is made of thickened steel plate by cutting and drilling. A movable slider 16 is slidably mounted on the movable slide rail 23. With the help of the movable slider 16 and the movable slide rail 23, the orientation adjustment movable frame 5 can move freely back and forth. The movable slider 16 is fixedly connected to the orientation adjustment movable frame 5. An adjusting bolt mounting plate 20 is fixedly mounted on the lower surface of the orientation adjustment movable frame 5. The adjusting bolt mounting plate 20 is made of thickened steel plate by cutting and drilling. The origin adjusting bolt 19 is connected to the adjusting bolt mounting plate 20 by threads and is locked twice by a nut.

[0030] Adjusting the position of the origin adjusting bolt 19 can control the distance between the adjusting bolt mounting plate 20 and the adjusting bolt abutment plate 21, thereby controlling the position of the orientation adjusting movable frame 5 when it is not squeezed by the pipe fitting. The appropriate position can improve the reliability and stability of the orientation adjustment of the female bend pipe fitting 3. If the orientation adjusting movable frame 5 is too far back, it may not produce the orientation adjustment effect. If the orientation adjusting movable frame 5 is too far forward, it may cause material jamming.

[0031] The left and right sides of the orientation adjustment frame 5 are symmetrically provided with a left return spring 18 and a right return spring 14. The rear end of the left return spring 18 is fitted onto the left return spring rear end fixing bolt 17, and its front end is fitted onto the left return spring front end fixing bolt 24 and connected by tension. The rear end of the right return spring 14 is fitted onto the right return spring rear end fixing bolt 15, and its front end is fitted onto the right return spring front end fixing bolt 13 and connected by tension.

[0032] The left return spring rear end fixing bolt 17 and the right return spring rear end fixing bolt 15 are symmetrically arranged on the left and right sides of the orientation adjustment movable frame 5, and the left return spring front end fixing bolt 24 and the right return spring front end fixing bolt 13 are symmetrically arranged on the movable slide rail fixing frame 22.

[0033] The left return spring 18 and the right return spring 14 can provide a forward restoring force to the orientation adjustment movable frame 5, so that the orientation adjustment movable frame 5 has a certain degree of flexibility when adjusting the orientation of the internal bend pipe 3, reducing the possibility of jamming and improving the stability of orientation adjustment.

[0034] An orientation adjustment friction rubber sheet 12 is provided in the gap of the orientation adjustment movable frame 5 and is fixed by pressing with an internal hex screw. The orientation adjustment friction rubber sheet 12 is cut from a wear-resistant rubber sheet.

[0035] Please refer to Figure 6 The carrier 9 consists of a carrier 28 and a female bend pipe positioning pin 27. The female bend pipe positioning pin 27 is inserted into the carrier 28 and tightened by a set screw.

[0036] In this embodiment, the guide limit rod 6 is made by cutting and bending a stainless steel rod and then covering it with a polytetrafluoroethylene tube; the orientation adjustment movable frame 5 is made by cutting, drilling, and grinding a thickened stainless steel plate; and the adjusting bolt mounting plate 20 is made by cutting and drilling a thickened steel plate.

[0037] The specific implementation process of this utility model device in the production process is as follows:

[0038] First, adjust the front and back positions of the origin adjusting bolt 19 so that the orientation adjusting movable frame 5, together with the orientation adjusting friction rubber sheet 12 above, can press against the female insert connector 26 of the female bend pipe fitting and also have a certain pressing force; then adjust the up and down and front and back positions of the overall fixing frame 4 of the orientation adjusting mechanism so that the all-plastic connector 25 of the female bend pipe fitting is just attached to the guide limit rod 6 in a right-facing posture.

[0039] Next, the device is activated, and the chain conveyor 2 drives the carrier 9 to move to the right. The front-end robot grabs the female bend pipe fitting 3 and places it on the female bend pipe fitting positioning pin 27 of the carrier 9. Then, the chain conveyor 2 drives the carrier 9, along with the female bend pipe fitting 3, to move to the right. Then, the all-plastic connector 25 of the female bend pipe fitting is guided and limited by the guide limit rod 6, while the female insert connector 26 of the female bend pipe fitting is squeezed by the orientation adjustment movable frame 5 and the orientation adjustment friction rubber sheet 12. As the female bend pipe fitting 3 moves to the right and is squeezed and rubbed by the orientation adjustment friction rubber sheet 12, the female bend pipe fitting 3 moves to the right while rotating counterclockwise on the female bend pipe fitting positioning pin 27 until the all-plastic connector 25 of the female bend pipe fitting is attached to the guide limit rod 6 with a rightward orientation, and finally enters the laser marking stage at the rear end in this orientation.

[0040] As each female bend pipe fitting is conveyed to the right, female bend pipe fittings with incorrectly oriented plastic connectors 25 are continuously rubbed counterclockwise by the orientation-adjusting friction rubber pads 12 until they finally enter the rear laser marking stage with their plastic connectors 25 facing right. This process is repeated. The device operation is complete.
