Description

Technical Field

[0001] This patent relates to the field of material conveying technology, specifically a rotary conveyor for warehousing equipment. Background Technology

[0002] During the production process, it is sometimes necessary to turn the materials around or change the direction of material transport. Therefore, a rotary conveyor is needed to carry the materials and change their direction of transport to send them into the next production line.

[0003] At present, the rotary conveyor consists of two main parts: a rotary base and a chain conveyor. The drive motor of the rotary base drives the rotary support device through a reducer, so that the main body of the chain conveyor rotates to a specified angle; at the same time, the drive motor of the chain conveyor drives the chain through sprockets to realize the conveying of materials.

[0004] However, when existing rotary conveyors are used to transport materials, if the materials are stacked, the materials are prone to shaking or even collapsing when the conveyor starts or stops. Therefore, a storage equipment rotary conveyor with a limiting structure is needed. Utility Model Content

[0005] The purpose of this patent is to provide a rotary conveyor for warehousing equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this patent provides the following technical solution: a rotary conveyor for storage equipment, comprising a base, a rotary mechanism and a chain conveyor, wherein the base is fixedly installed on the external ground, the rotary mechanism is installed at the center of the upper wall of the base, and the chain conveyor is installed above the rotary mechanism, and both the rotary mechanism and the chain conveyor are electrically connected to an external PLC controller;

[0007] The upper wall of the chain conveyor is equipped with a limiting mechanism, which includes a fixed rod, a crossbeam, collars, and a pressure plate. The fixed rod is installed on the frame on both sides of the chain conveyor. Collars are installed at both ends of the crossbeam, and the two collars are respectively sleeved on the outside of the two fixed rods. A pressure plate is installed on the lower wall of the crossbeam, which can press the material.

[0008] Preferably, the side wall of the collar is provided with a threaded hole, and a bolt is screwed into the threaded hole. The bolt passes through the threaded hole, penetrates the side wall of the collar, and fits against the side wall of the fixing rod.

[0009] Preferably, the rotary mechanism includes a rotary support base, a motor, a gearbox, a worm gear, and a worm. The rotary support base is installed at the center above the base, and a worm gear is installed on the outer side of the rotary support base. The motor is installed on the upper wall of the base and is electrically connected to an external PLC controller. A gearbox is installed at the output end of the motor, and a worm gear is installed at the output end of the gearbox. The worm gear is meshed with the worm gear.

[0010] Preferably, the pressure plate is made of transparent acrylic material, and a relief groove is provided on the upper wall of the pressure plate. A fixed shaft is installed in the relief groove, and a roller is rotatably installed on the outside of the fixed shaft. The roller can fit against the upper wall of the external material.

[0011] Preferably, support feet are installed at all four corners of the base. Each support foot includes a screw, a support plate, and a locking nut. Holes are provided at all four corners of the base. The screw is inserted into the hole. A support plate is installed on the lower wall of the screw.

[0012] Preferably, a counterweight is installed at the end of the collar away from the pressure plate.

[0013] Compared with existing technologies, the beneficial effects of this patent are:

[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-3 This patent provides a technical solution: a rotary conveyor for warehousing equipment, including a base 1, a rotating mechanism 2, and a chain conveyor 3. The base 1 is fixedly installed on the external ground and serves as the basic support structure for the entire equipment. It is supported on the ground by support legs 10. The rotating mechanism 2 is installed at the center of the upper wall of the base 1. The rotating mechanism 2 is the core component for realizing the rotation of the chain conveyor 3. It can drive the chain conveyor 3 above to rotate 360 ​​degrees or within a certain angle range in the horizontal direction to adapt to different material conveying needs in warehousing operations. The chain conveyor 3 is installed above the rotating mechanism 2. Both the rotating mechanism 2 and the chain conveyor 3 are electrically connected to an external PLC controller. The chain conveyor 3 is responsible for carrying and conveying materials. Through the continuous transmission of the chain, the materials are conveyed from one position to another. An external PLC controller (programmable logic controller) precisely controls the rotary mechanism 2 and the chain conveyor 3 through a preset program. It can flexibly adjust parameters such as the operating speed, rotation angle, and start-stop time of the equipment according to the actual operation process, so as to realize automated operation and improve the efficiency and accuracy of warehousing and logistics.

[0021] A limiting mechanism 4 is installed on the upper wall of the chain conveyor 3. The limiting mechanism 4 is designed to prevent material from shifting or slipping during the operation of the chain conveyor 3, ensuring the safety and stability of material conveying. The limiting mechanism 4 includes a fixed rod 41, a crossbeam 42, collars 43, and a pressure plate 44. The fixed rod 41 is installed on the frame on both sides of the chain conveyor 3. Collars 43 are installed at both ends of the crossbeam 42, and the two collars 43 are respectively fitted onto the outside of the two fixed rods 41. A pressure plate 44 is installed on the lower wall of the crossbeam 42. The pressure plate 44 can press down on the material. The pressure plate 44 is in direct contact with the material and uses its own weight to confine the material within the conveying range of the chain conveyor 3, preventing the material from leaving the conveyor due to shaking, acceleration, deceleration, or other factors during conveying. This structural design is simple and practical, effectively improving the reliability of material conveying.

[0022] The cross frame 42 is fitted onto the fixed rod 41 by collars 43 at both ends, and can slide up and down along the fixed rod 41 to adjust the distance between the pressure plate 44 and the upper surface of the chain conveyor 3 to accommodate materials of different heights.

[0023] Specifically, the side wall of the collar 43 has a threaded hole 5, into which a bolt 6 is screwed. The bolt 6 passes through the threaded hole 5 and engages with the side wall of the fixing rod 41. The use of the threaded hole 5 and the bolt 6 is to fix the collar 43 on the fixing rod 41. When it is necessary to adjust the height of the pressure plate 44 to accommodate different materials, the bolt 6 can be loosened, allowing the collar 43 to slide freely on the fixing rod 41. After adjusting the pressure plate 44 to the appropriate height, the bolt 6 is tightened. At this time, the end of the bolt 6 presses tightly against the side wall of the fixing rod 41, and the friction prevents the collar 43 from continuing to slide, thereby stably fixing the pressure plate 44 in the required position. This adjustment method is convenient to operate, can quickly and accurately adjust the height of the limiting mechanism 4 to meet the needs of different working conditions, and has a good tightening effect, ensuring that the pressure plate 44 will not move arbitrarily during equipment operation.

[0024] Specifically, the rotary mechanism 2 includes a rotating support base 21, a motor 22, a gearbox 23, a worm gear 24, and a worm 25. The rotating support base 21 is installed at the center above the base 1, providing stable support and a rotational foundation for the entire rotary mechanism 2. It is installed at the center of the base 1 and can bear the weight of the chain conveyor 3 and the materials, ensuring the stability of the chain conveyor 3 during rotation. The rotating support base 21 can be divided into two parts: the lower part is directly connected to the base 1 and cannot rotate, while the upper part is connected to the chain conveyor 3 and can rotate. The worm gear 24 is installed on the upper rotatable part. The worm gear 24 is installed on the outer side of the rotating support base 21. The motor 22 is installed on the upper wall of the base 1 and is electrically connected to an external PLC controller. The motor 22 is connected to a gearbox 23 at its output end, and a worm gear 25 is installed at the output end of the gearbox 23. The worm gear 25 is meshed with a worm wheel 24. The motor 22 serves as the power source for the rotary mechanism 2. Under the control of an external PLC controller, the motor 22 starts, stops, and adjusts its speed. Since the output speed of the motor 22 is usually high, it is not suitable to directly drive the chain conveyor 3 to rotate. Therefore, the output speed of the motor 22 needs to be reduced by the gearbox 23, while the output torque is increased to meet the power requirements for the rotary mechanism 2 to drive the chain conveyor 3 to rotate. The worm wheel 24 and the worm gear 25 form a gear transmission pair. Through the meshing of the gears, the power output by the gearbox 23 is transmitted to the rotating support base 21, so that the rotating support base 21 can drive the chain conveyor 3 to rotate.

[0025] Specifically, the pressure plate 44 is made of transparent acrylic. The choice of transparent acrylic for the pressure plate 44 is due to two reasons: firstly, acrylic's good transparency allows operators to clearly observe the state of the material beneath it, facilitating timely detection of problems during material conveying; secondly, acrylic possesses sufficient strength and wear resistance to meet the pressure plate 44's function of pressing and limiting the material, while its relatively light weight facilitates installation and adjustment. The upper wall of the pressure plate 44 has a clearance groove 8, within which a fixed shaft 9 is installed. A roller 7 is rotatably mounted on the outer side of the fixed shaft 9. The roller 7 can be attached to the upper wall of the external material. When the material is conveyed on the chain conveyor 3, the roller 7 can rotate with the movement of the material. This can reduce the friction between the pressure plate 44 and the material, avoid damage to the material surface due to excessive friction, and also help the material to be conveyed smoothly, ensuring that the material can pass through the chain conveyor 3 smoothly while being limited. In order to ensure that both sides of the pressure plate 44 are in the same horizontal plane, a scale line can be set on its fixed rod 41. The position of the collar 43 can be precisely adjusted by observing the scale line, thereby ensuring that the pressure plate 44 is flat.

[0026] Specifically, support feet 10 are installed at each of the four corners of the base 1. Each support foot 10 includes a screw 101, a support plate 102, and a locking nut 103. Holes are provided at each of the four corners of the base 1, and the screw 101 is inserted into the holes. The support plate 102 is installed on the lower wall of the screw 101, and the locking nut 103 is rotatably installed on the outer side of the screw 101. The locking nut 103 can fit against the side wall of the base 1. (See attached figure) Figure 1 Each screw 101 has two locking nuts 103 rotatably mounted on its outer side. The two locking nuts 103 are respectively located on the upper and lower sides of the base 1, and the screw 101 is fixed by clamping to ensure that the screw 101 will not rotate.

[0027] Specifically, a counterweight 7 is installed at the end of the collar 43 away from the pressure plate 44, and a counterweight 11 is installed at the end of the collar 43 away from the pressure plate 44. This is mainly to balance the torque generated by the pressure plate 44 on the collar 43, so that the crossbar 42 can maintain better stability on the fixed rod 41.

[0028] Working principle: The material moves to one side of the device via an external conveyor belt. Then, the PLC controls the motor 22 to start, which drives the chain conveyor 3 to rotate through the cooperation of the worm gear 24 and worm 25, making the chain conveyor 3 parallel to the external conveyor belt. The external conveyor belt and the chain conveyor 3 then run at the same speed, moving the material above the chain conveyor 3. At the same time, the pressure plate 44 directly contacts the material to limit its movement. Once the material has completely entered the chain conveyor 3, the motor 22 can be started again to drive the chain conveyor 3 to rotate, making it parallel to another external conveyor belt. Then, the chain conveyor 3 can be started to move the material onto the other conveyor belt, completing the rotational conveying of the material.
