Description

Technical Field

[0001] This utility model relates to the technical field of automatic packaging of PPR pipe fittings, specifically to a universal material sensing device for centrifugal conveying of pipe fittings. Background Technology

[0002] In the automated packaging process of some PPR pipe fittings, the PPR pipe fittings are first lifted and conveyed from the storage silo by an inclined belt conveyor, then fall into a centrifugal sorting conveyor. The centrifugal sorting conveyor then centrifugally sorts and conveys the fittings into a fixed position before they enter the belt conveyor for online conveying, marking, and packaging. Because too little material in the centrifugal sorting conveyor will affect packaging efficiency, while too much material can cause problems such as blockage, jamming, or even overloading of the centrifugal sorting conveyor.

[0003] Therefore, a sensing device is needed to detect the pipe materials within the centrifugal conveyor and trigger corresponding signals to control the feeding action of the upstream inclined belt conveyor. This ensures that the material within the centrifugal conveyor remains within a reasonable range that guarantees both efficiency and stability. Furthermore, the pipe materials are conveyed in an outward spiral motion during centrifugal conveyor operation. If the sensing device has requirements regarding the material movement direction, it will increase the difficulty of installation and commissioning and is prone to sensing malfunctions. Therefore, the device also needs to be compatible with the installation requirements of various conveying directions of the pipe materials to improve the reliability of material sensing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a universal material sensing device for centrifugal conveying of pipe fittings, which has the function of sensing the centrifugally conveyed pipe fittings and can achieve 360-degree universal sensing, reducing the difficulty of installation and debugging and improving the reliability of sensing.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A universal material sensing device for centrifugal conveying of pipe fittings includes a universal sensing overall mounting frame, on which a material sensing mechanism for centrifugal conveying of pipe fittings is mounted. The universal sensing overall mounting frame is provided with a left-right position adjustment support rod assembly for adjusting its left-right position, and the left-right position adjustment support rod assembly is provided with a right-right position adjustment support rod assembly for adjusting the up-down position of the universal sensing overall mounting frame.

[0006] Furthermore, the material sensing mechanism includes a material sensing fixing limit ring and a material sensing swing rod. The material sensing fixing limit ring is connected and fixed to the universal sensing overall mounting frame by a front-side fixing bolt and a rear-side fixing bolt with holes. The material sensing swing rod passes through the bottom of the material sensing fixing limit ring and has a material sensing contact metal ball welded to it. The material sensing contact metal ball is a hollow metal ball. The material sensing swing rod is made by cutting, drilling and grinding a metal rod. Near the upper end, there is a cylindrical protrusion with four small round holes on the top of the cylindrical protrusion.

[0007] Furthermore, the inner wall surface of the material sensing fixing and limiting ring is respectively provided with a left-side connecting reset spring, a right-side connecting reset spring, a front-side connecting reset spring, and a rear-side connecting reset spring along its circumferential direction. One end of the left-side connecting reset spring is hooked onto the round hole of the left-side fixing bolt, and the other end is hooked onto the small round hole on the left side of the cylindrical protrusion of the material sensing swing rod; one end of the right-side connecting reset spring is hooked onto the round hole of the right-side fixing bolt, and the other end is hooked onto the small round hole on the right side of the cylindrical protrusion of the material sensing swing rod; one end of the front-side connecting reset spring is hooked onto the round hole of the front-side fixing bolt, and the other end is hooked onto the small round hole on the front side of the cylindrical protrusion of the material sensing swing rod; one end of the rear-side connecting reset spring is hooked onto the round hole of the rear-side fixing bolt, and the other end is hooked onto the small round hole on the rear side of the cylindrical protrusion of the material sensing swing rod.

[0008] Furthermore, the left-side hole-fixing bolt and the right-side hole-fixing bolt are fixed to the material sensing and fixing limit ring by threaded connection.

[0009] Furthermore, the upper end of the material sensing swing rod is provided with an inductive proximity switch, which is connected to the universal sensing overall mounting bracket by a thread and then locked in place by two nuts.

[0010] Furthermore, the left and right position adjustment support rod assembly includes a left and right position adjustment support rod, a T-shaped clamp, and a cross clamp. The T-shaped clamp is connected and fixed to the universal sensor mounting bracket by an internal hex screw. The left end of the left and right position adjustment support rod is inserted into the T-shaped clamp and clamped and fixed by tightening the locking bolt on the T-shaped clamp, and the right end is inserted into the cross clamp and clamped and fixed by tightening the locking bolt on the cross clamp.

[0011] Furthermore, the left and right position adjustment support rod is made by cutting and grinding steel rods.

[0012] Furthermore, the up-down position adjustment support rod assembly includes an up-down position adjustment support rod and a fixed clamp. The upper end of the up-down position adjustment support rod is inserted into the cross clamp and clamped and fixed by tightening the locking bolt on the cross clamp. The lower end is inserted into the fixed clamp and clamped and fixed by tightening the two locking bolts on the fixed clamp.

[0013] Furthermore, the vertical position adjustment support rod is made by cutting and grinding steel rod; the fixed clamp is provided with 4 mounting holes for installation; the universal induction overall mounting frame is made by cutting, welding and drilling stainless steel plate; and the material sensing fixed limit ring is made by cutting and drilling stainless steel tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1) The device of this utility model is composed of a set universal induction overall mounting frame, an inductive proximity switch, a material sensing swing rod, etc. The inductive proximity switch is installed on the universal induction overall mounting frame to sense the material sensing swing rod, forming a highly practical universal material sensing device for centrifugal conveying of pipe fittings. It effectively avoids the problems that the packaging efficiency will be affected if there is too little material in the centrifugal material conveyor during operation, while the problem that the centrifugal material conveyor will be blocked, jammed, or even overloaded due to too much material. 2) The adjustable bracket composed of the cross clamp, T-clamp, vertical position adjustment support rod and horizontal position adjustment support rod in this utility model allows the universal induction overall mounting frame and the mechanism above to be adjusted in height and position, thus making it compatible with centrifugal material conveyors of different sizes and heights as well as material sensing requirements of different specifications, with good compatibility. 3) The left-side, right-side, front-side, and rear-side reset springs of this utility model are used to connect the material sensing swing rod. On the other hand, the springs' extension force allows the material sensing swing rod to swing in any direction and automatically return to its original position, thus improving the stability and reliability of material sensing. 4) The material sensing contact metal ball of this utility model adopts a hollow metal ball design, which reduces the overall weight of the device and avoids the situation where the material cannot push the metal ball when sensing the tube, thus failing to generate a trigger signal. In addition, each surface of the metal ball is consistent, further meeting the requirements of universal sensing. 5) This utility model device has a novel design and reasonable concept. It mainly has the function of sensing the pipe materials conveyed by centrifugation and can realize 360-degree universal sensing to reduce the difficulty of installation and debugging and improve the reliability of sensing. At the same time, it has a simple structure, saves costs, has minimal dependence on the environment, and is easy to operate. Attached Figure Description

[0017] 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.

[0018] Please refer to Figure 1-4 As shown, a universal material sensing device for centrifugal conveying of pipe fittings includes a universal sensing overall mounting frame 5, on which a material sensing mechanism for centrifugal conveying of pipe fittings is mounted. The universal sensing overall mounting frame 5 is provided with a left-right position adjustment support rod assembly for adjusting its left-right position, and the left-right position adjustment support rod assembly is provided with a right-right position adjustment support rod assembly for adjusting the up-down position of the universal sensing overall mounting frame 5.

[0019] In this embodiment, the universal sensor mounting bracket 5 is made by cutting, welding, and drilling holes in a stainless steel plate. The material sensing and fixing limit ring 3 is made by cutting and drilling holes in a stainless steel tube.

[0020] The material sensing mechanism includes a material sensing fixing and limiting ring 3 and a material sensing swing rod 2. The material sensing fixing and limiting ring 3 is connected and fixed to the universal sensing overall mounting frame 5 by a front-side fixing bolt 11 and a rear-side fixing bolt 16. The material sensing swing rod 2 passes through the bottom of the material sensing fixing and limiting ring 3 and has a material sensing contact metal ball 1 welded to it. The material sensing contact metal ball 1 is a hollow metal ball to reduce the overall weight of the device and prevent the material from being unable to push the metal ball when sensing the material in the tube. The material sensing swing rod 2 is made by cutting, drilling, and grinding a metal rod. Near its upper end, there is a cylindrical protrusion with four small round holes on its upper side.

[0021] The inner wall of the material sensing fixing limit ring 3 is provided with a left-side connecting reset spring 13, a right-side connecting reset spring 18, a front-side connecting reset spring 12, and a rear-side connecting reset spring 15 along its circumferential direction. One end of the left-side connecting reset spring 13 is hooked onto the round hole of the left-side fixing bolt 14, and the other end is hooked onto the small round hole on the left side of the cylindrical protrusion of the material sensing swing rod 2. One end of the right-side connecting reset spring 18 is hooked onto the round hole of the right-side fixing bolt 17, and the other end is hooked onto the small round hole on the right side of the cylindrical protrusion of the material sensing swing rod 2. One end of the front-side connecting reset spring 12 is hooked onto the round hole of the front-side fixing bolt 11, and the other end is hooked onto the small round hole on the front side of the cylindrical protrusion of the material sensing swing rod 2. One end of the rear-side connecting reset spring 15 is hooked onto the round hole of the rear-side fixing bolt 16, and the other end is hooked onto the small round hole on the rear side of the cylindrical protrusion of the material sensing swing rod 2.

[0022] The left side is connected to the reset spring 13, the right side is connected to the reset spring 18, the front side is connected to the reset spring 12, and the rear side is connected to the reset spring 15. On the one hand, the reset spring 13 is connected to the reset spring 2, and on the other hand, the springs allow the material sensing swing rod 2 to swing in any direction and automatically return to its original position.

[0023] The left-side fixed bolt 14 and the right-side fixed bolt 17 are fixed to the material sensing and fixing limit ring 3 by threaded connection.

[0024] An inductive proximity switch 4 is provided at the upper end of the material sensing swing arm 2. The inductive proximity switch 4 is connected to the universal sensing mounting bracket 5 by threads and then secured with two nuts. There is no trigger signal when the upper end of the material sensing swing arm 2 is below the inductive proximity switch 4, and a trigger signal is generated when the upper end of the material sensing swing arm 2 moves away from below the inductive proximity switch 4.

[0025] The left and right position adjustment support rod assembly includes a left and right position adjustment support rod 7, a T-shaped clamp 6, and a cross clamp 8. The T-shaped clamp 6 is connected and fixed to the universal sensor mounting bracket 5 by an internal hex screw. The left end of the left and right position adjustment support rod 7 is inserted into the T-shaped clamp 6 and clamped and fixed by tightening the locking bolt on the T-shaped clamp 6. The right end of the rod is inserted into the cross clamp 8 and clamped and fixed by tightening the locking bolt on the cross clamp 8.

[0026] In this embodiment, the left and right position adjustment support rod 7 is made by cutting and grinding a steel rod.

[0027] The vertical position adjustment support rod assembly includes a vertical position adjustment support rod 9 and a fixed clamp 10. The upper end of the vertical position adjustment support rod 9 is inserted into the cross clamp 8 and clamped and fixed by tightening the locking bolt on the cross clamp 8. The lower end is inserted into the fixed clamp 10 and clamped and fixed by tightening the two locking bolts on the fixed clamp 10.

[0028] The vertical position adjustment support rod 9 is made of steel rod by cutting and grinding; the fixed clamp 10 is provided with 4 mounting holes for installation; the universal sensor overall mounting frame 5 is made of stainless steel plate by cutting, welding and drilling; the material sensing fixed limit ring 3 is made of stainless steel pipe by cutting and drilling.

[0029] After loosening the locking bolts on the T-clamp 6 and the cross clamp 8, the vertical height and horizontal position of the universal induction overall mounting bracket 5 and the upper mechanism can be adjusted to ensure good compatibility of the device.

[0030] The specific implementation process of this utility model device in the production process is as follows: The device is installed next to the centrifugal feeding conveyor of the automatic packaging line through the four mounting holes on the fixed clamp 10. At the same time, the vertical height and horizontal position of the universal induction overall mounting frame 5 are adjusted by the cross clamp 8, T-clamp 6, vertical position adjustment support rod 9, and horizontal position adjustment support rod 7 to match the size of the centrifugal feeding conveyor and the sensing requirements of the current material specifications. Then, the automatic packaging line and this device are started. The pipe material is lifted and conveyed from the front-end inclined belt conveyor and falls into the centrifugal distributing conveyor for centrifugal distributing. At this time, since there is still a relatively small amount of pipe material in the centrifugal distributing conveyor, the pipe material has not yet come into contact with the material sensing contact metal ball 1. Therefore, the material sensing swing rod 2 is still in a natural hanging state, and its upper end is still below the inductive proximity switch 4. At this time, no trigger signal is generated, and the inclined belt conveyor continues to feed material into the centrifugal distributing conveyor.

[0031] After a period of time, when the material in the tubular components inside the centrifugal conveyor has reached a certain height, i.e., when the internal material is sufficient, the spiraling material in the tubular components touches the material-sensing contact metal ball 1, causing it to shift in the direction of material movement. The material-sensing swing rod 2 then swings in the same direction. At this time, the upper end of the material-sensing swing rod 2 moves away from below the inductive proximity switch 4, causing the inductive proximity switch 4 to generate a trigger signal to the inclined belt conveyor, thus stopping the inclined belt conveyor from running and stopping the feeding of material into the centrifugal conveyor.

[0032] After a period of time, a large amount of material in the centrifugal conveyor has been transported out for subsequent marking and packaging processes. When the height of the material in the pipes inside the centrifugal conveyor decreases, indicating that the internal material is becoming insufficient, the material in the pipes detaches from the material-sensing contact metal ball 1. Under the combined restoring force of the metal ball's gravity and the left-side, right-side, front-side, and rear-side reset springs 13, 18, 12, and 15, the material-sensing swing rod 2 returns to its natural drooping state. The upper end of the material-sensing swing rod 2 returns to below the inductive proximity switch 4. At this point, the trigger signal disappears, and the inclined belt conveyor resumes operation, continuing to feed material into the centrifugal conveyor until the material in the pipes inside the centrifugal conveyor reaches a sufficient height to fill the space. This process is repeated. The device operation is complete.
