Description

Technical Field

[0001] This utility model relates to a conveying device, and more particularly to a rotary conveyor table. Background Technology

[0002] The nest box conveyor line is a straight line, and there are many problems with the flow and docking at the corners. For example, the original equipment's docking structure with ABO has an unreasonable single cylinder design, with different weights at both ends, causing one end of the mechanism to tilt during docking and resulting in inaccurate docking. There is no connection between the cylinder and the lifting mechanism and no buffer device. The cylinders at both ends of the lifting mechanism work independently and are not synchronized. During the lifting process, the mechanism is often uneven, causing the nest boxes to move intermittently and not stably. During the descent, the mechanism falls freely under gravity, which is very noisy. Without buffer devices and protective devices, the nest boxes often fall when they reach the corners.

[0003] Employing an independent rotating mechanism helps solve the aforementioned problems. CN 218595364 U discloses a rotating transfer device that uses a geared motor to drive a rotary table to rotate horizontally via a worm gear mechanism, allowing the rotary table to rotate at any angle. The object to be transferred is conveyed through a conveying work area formed by multiple rollers arranged side-by-side above the rotary table, enabling better connection of the production line. However, this design features a rubber-coated roller on the outer side of one end of the corresponding conveying work area on the rotary table. This rubber-coated roller is shorter than the main roller and is a non-powered roller. If the object to be transferred is lightweight and has low inertia, there is a risk of it getting stuck between the rubber-coated roller and the main roller, hindering smooth transfer. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a rotating conveyor to achieve smooth transfer of nest boxes at corners.

[0005] Technical solution: The present invention provides a rotary conveyor table, comprising a moving mechanism and a rotating mechanism arranged vertically. The moving mechanism includes a driving roller, a driven roller driven by the driving roller, and several short rollers located at the inlet end of the moving mechanism, the length of which is less than that of the driven roller. The length of the short rollers decreases as the distance between the short rollers and the driven rollers increases. The short rollers are driven to rotate by the driving roller and / or the driven roller.

[0006] Preferably, the short roller is connected to the driving roller and / or the driven roller via a first belt, and the section between the driven roller and the adjacent short roller and the section between the short roller and the next short roller are narrowed.

[0007] Preferably, the driving roller and / or driven roller and short roller are each provided with an annular first limiting groove, and the first belt is located in the first limiting groove.

[0008] Preferably, the driving roller is connected to the driven roller via a second belt, the second belt being located outside the first belt, and the driving roller and the driven roller are respectively provided with annular second limiting grooves.

[0009] Preferably, the inlet end of the moving mechanism is provided with a feeding detection sensor, and the end end is provided with a positioning detection sensor and a limiting member to prevent the nest box from moving along the moving mechanism.

[0010] Preferably, the moving mechanism is provided with a cover.

[0011] Preferably, the driving roller, driven roller, and short roller are located above the base plate of the moving mechanism, the driving roller is connected to the power mechanism, and the power mechanism is located below the base plate.

[0012] Preferably, the rotating mechanism includes a driving gear and a driven gear, the driving gear, the driven gear and the mounting plate are rotatably connected and mesh with each other, and a pad is provided on the driven gear, the pad is connected to the base plate of the moving mechanism.

[0013] Preferably, the mounting plate is provided with a plurality of detection mechanisms, and the pad is provided with a detection block that cooperates with the detection mechanisms.

[0014] Preferably, the height of the pad is greater than that of the power mechanism.

[0015] Beneficial effects: Compared with the prior art, this utility model has the following advantages: 1. Smooth transfer of nest boxes at corners: The short roller at the entrance end is connected to the active roller or driven roller. The short roller has power, so even if the nest box is underpowered, it can be smoothly transferred to the top of the moving mechanism, ensuring smooth transfer; 2. It has buffering and protection functions. The moving mechanism has limiting parts to prevent the nest box from falling when rotating, effectively protecting it and reducing the defect rate; 3. Detection accuracy: The addition of a cover avoids environmental interference and ensures detection accuracy; 4. By adopting an independent rotating conveyor, the product flow is achieved by the rotation of the rotating table plane, which solves the problems of inaccurate docking and unstable operation of the original equipment, reduces docking errors, and improves the reliability and production efficiency of the equipment.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the rotating conveyor mainly consists of two parts: a moving mechanism 2 and a rotating mechanism 1. The moving mechanism 2 is located above the rotating mechanism 1. The moving mechanism 2 transports the nest box 3 to the top of the rotating conveyor. The rotating mechanism 1 drives the nest box 3 to rotate, realizing the transfer of the nest box at the corner.

[0022] like Figure 2 The moving mechanism 2 includes a parallel driving roller 21 and a driven roller 22, which are rotatably connected to the base plate 20. The driving roller 21 is connected to the power mechanism 23. The two ends of the driving roller 21 and the two ends of the driven roller 22 are connected by a belt or chain. The driven roller 22 is driven to rotate by the driving roller 21 to achieve synchronous movement. The driven roller 22 faces the entrance end of the moving mechanism 2. The entrance end of the moving mechanism 2 is also provided with short rollers 24. There can be one or more short rollers 24. The length of the short roller 24 itself decreases as the distance between the short roller 24 and the driven roller 22 increases. That is, the short roller 24 closest to the driven roller 22 is shorter than the driven roller 22, and the next short roller 24' adjacent to the short roller 24 is shorter than the short roller 24, so as to achieve a smooth transition between the entrance of the moving mechanism 2 and the linear conveying mechanism (not shown). The two ends of the short roller 24 are rotatably connected to the base plate 20 through a bracket.

[0023] Short roller 24 is connected to either drive roller 21 or driven roller 22 for synchronized operation. This prevents the nest box from failing to move fully above the rotating conveyor during transfer due to insufficient inertia, thus ensuring the nest box doesn't fall off when the rotating conveyor rotates and affecting the continuity of transfer. When there is only one short roller 24, it is connected to drive roller 21 via belt 25. The section of driven roller 22 corresponding to the length of short roller 24 is narrowed to allow belt 25 to pass over driven roller 22 and drive short roller 24 to rotate. When there are two short rollers 24, short roller 24' is connected to driven roller 22 via belt 25. The section of short roller 24 corresponding to the length of short roller 24' is narrowed to allow belt 25 to pass over short roller 24 and drive short roller 24' to rotate.

[0024] Annular limiting grooves 212 and 241 (or 241') may be correspondingly provided on the driving roller 21 or driven roller 22 and short roller 24 (or short roller 24') to limit the relative position of the belt 25. If the driving roller 21 and driven roller 22 are connected by a belt, annular limiting grooves 211 and 221 may also be correspondingly provided at both ends of the driving roller 21 and driven roller 22.

[0025] The inlet end of the moving mechanism 2 is equipped with a feed detection sensor 26, and the end end of the moving mechanism 2 is equipped with a position detection sensor 27 and a limiting member 28. The limiting member 28 prevents the nest box from continuing to move along the moving mechanism 2, and the position detection sensor 27 sends a signal to the rotating mechanism 1, which drives the nest box to rotate.

[0026] The moving mechanism 2 is equipped with a cover 29 to ensure that the signals of the feed detection sensor 26 and the position detection sensor 27 are free from interference, and to further prevent the nest box from falling during rotation. The power mechanism 23 is located below the base plate 20.

[0027] like Figure 3 , Figure 4 The rotating mechanism 1 includes a driving gear 11 and a driven gear 12. The driving gear 11, driven gear 12, and mounting plate 10 are rotatably connected and mesh with each other. The driving gear 11 is connected to the drive mechanism 13. A pad 15 is provided on the driven gear 12, and the pad 15 rotates synchronously with the driven gear 12. The pad 15 is connected to the base plate 20 of the moving mechanism. The mounting plate 10 is provided with multiple detection mechanisms 16, and the pad 15 is provided with detection blocks 14 that cooperate with the detection mechanisms 16. The height of the pad 15 is greater than that of the power mechanism 23 to avoid interference during rotation. The drive mechanism 13 is a geared motor.
