Description

Technical Field

[0001] The utility model relates to the technical field of production equipment in the packaging industry, in particular to a double-channel diverter. Background Art

[0002] In the existing packaging production lines of the beer, beverage and other food packaging industries, it is usually necessary to divide a single channel into multiple channels for transportation to improve transportation efficiency and facilitate subsequent distribution. At the same time, at the front end of the product conveyor line, according to the needs of the palletizing pattern, because the specifications of the palletizing pallets are unified, the arrangement of different packaging boxes on the palletizing pallets is different, it is often necessary to turn the packaging boxes input vertically into horizontal arrangement, or turn the packaging boxes input horizontally into vertical arrangement, to meet the needs of subsequent production processes.

[0003] The existing technology mainly uses three methods to achieve steering:

[0004] 1. The fixed sidewall method is adopted. The fixed sidewall is set above the conveyor belt. When the box moves forward on the conveyor belt, it will turn to the side without obstruction when encountering the fixed sidewall. The fixed sidewall method cannot achieve compatibility with boxes arranged vertically and horizontally; and because the moving speed of the packaging box is very fast, direct collision with the movable sidewall is easy to cause the box to rebound and produce irregular steering effects. Patent CN219340802U discloses a packaging box steering device, including a platform and a baffle. The baffle is set above the platform, including a sidewall for steering the box and a ball guardrail for guiding the box to align. The sidewall is provided with a third cylinder for forming a pneumatic buffer. The third cylinder is arranged in the opposite direction along the conveyor line, which can prevent the box from rebounding when it is quickly turned; it is compatible with boxes arranged vertically and horizontally; the structure is simple and occupies less space, and the packaging boxes are neatly arranged after the steering is completed quickly.

[0005] 2. Patent CN210064153U discloses a 90° reversing belt conveyor, including a belt conveying assembly, a reversing assembly and a base. The belt conveying assembly includes a left conveying assembly and a right conveying assembly that are spaced and synchronously driven, and are used to convey materials. The reversing assembly is used to drive the belt conveying assembly to complete a 90° reversal, and the base is located below the reversing assembly to support the reversing assembly. With the help of the reversing assembly, the reversing turning of the belt conveying assembly is realized, which is highly efficient and has low equipment cost.

[0006] 3. Patents CN207903448U and CN203332919U disclose that the box is turned by two parallel differential conveyor lines. Half of the box falls on the slow conveyor belt and the other half falls on the fast conveyor belt. While the conveyor belt drives the box forward, the box can be turned because of the speed difference on both sides of the bottom of the box. The compatibility of the differential conveyor belt method with the boxes arranged vertically and horizontally can be achieved by continuously changing the conveyor belt speed.

[0007] At present, the existing technology mainly has the following technical problems:

[0008] 1. The steering function of the existing packaging box is mainly achieved by using a cylinder on the side of the horizontal conveyor line to impact and hit the packaging box to make the packaging box turn in a specified direction. However, this process causes certain damage and / or loss to the packaging box, which easily leads to defective products. In addition, the cylinder is subjected to radial force impact for a long time, has a relatively short service life, and requires frequent maintenance. In addition, such equipment needs to be installed with protective isolation devices, which occupies limited production space.

[0009] 2. The existing method of using a reversing component to achieve steering requires adding a reversing component to the belt conveyor, and some even require adding a lifting mechanism to drive the lifting mechanism to lift the reversing component, which affects the speed and rhythm of the box steering.

[0010] 3. The existing differential conveyor line mainly uses the friction generated by the speed difference between the conveyor belt and the bottom of the packaging box to change the upward movement trajectory of the packaging box, which is suitable for square and heavy products. However, because the conveyor belt and the bottom of the packaging box are in overall contact, the friction generated is more concentrated in the middle of the packaging box, which affects the speed of the packaging box turning and the production rhythm. Summary of the invention

[0011] The purpose of the utility model is to solve the deficiencies of the prior art and to provide a dual-lane diverter which can not only realize the function of diverting packaging boxes without collision or damage, but also realize the function of dual-lane on-demand diverting with minimal configuration.

[0012] In order to achieve the above object, the utility model provides the following technical solutions:

[0013] A double-track diverter comprises a frame, a conveying chain net, a left belt conveyor and a right belt conveyor.

[0014] The frame is provided with:

[0015] A conveyor chain network is located at the top of the entire plane of the frame and is connected by a plurality of ball module belts arranged along the length direction of the conveyor chain network. It is laid on the entire plane of the frame to form a first layer of support surface and can transport the packaging boxes placed on the first layer of support surface forward.

[0016] The left belt conveyor is distributed on the left side of the frame, is located below the first layer of support surface formed by the conveying chain net, and is tightly fitted with the balls of the conveying chain net to form a second layer of support surface.

[0017] The right belt conveyor is distributed on the right side of the frame, is located below the first layer of support surface formed by the conveying chain net, and is tightly fitted with the balls of the conveying chain net to form a second layer of support surface.

[0018] Furthermore, the conveyor chain network includes several groups of side-by-side and parallel universal ball bearings, which are evenly dispersed and embedded in the flexible plastic mesh belt chain to form the ball bearing module belt, and then multiple ball bearing module belts are connected together along the length direction of the conveyor chain network and laid on the entire plane of the frame to form the conveyor chain network.

[0019] Furthermore, the conveyor chain net balls can be arranged as needed according to the shape characteristics of the packaging box body. The balls are placed on both sides of the bottom of the packaging box, and the middle part of the packaging box body is suspended above the conveyor chain net, concentrating the friction force on both sides of the bottom of the packaging box, providing greater torque for the steering of the packaging box.

[0020] Furthermore, the left belt conveyor is a roller-driven belt conveyor line, comprising a belt, two roller brackets, two rollers arranged on the roller brackets, and a left belt drive motor arranged on the frame and capable of driving the rollers to rotate synchronously. The left belt drive motor is mounted on the left bracket of the frame, the drive shaft of the motor is connected to the rollers through a drive belt, the rotation of the drive shaft of the motor drives the rollers to rotate, the two ends of the belt are wound around the rollers, and the belt is driven to move by the rotation of the rollers.

[0021] Furthermore, the right belt conveyor is a roller-driven belt conveyor line, including a belt, two roller brackets, two rollers arranged on the roller brackets, and a right belt drive motor arranged on the frame and capable of driving the rollers to rotate synchronously. The right belt drive motor is installed on the right bracket of the frame, the drive shaft of the motor is connected to the rollers through a drive belt, the rotation of the drive shaft of the motor drives the rollers to rotate, the two ends of the belt are wound on the rollers, and the belt is driven to move by the rotation of the rollers.

[0022] The steering principle of the dual-channel steering gear is as follows:

[0023] 1. When the box does not need to turn, the left / right belt drive motor stops or does not start, and the box is transported forward on the conveyor chain alone and directly passes through the first layer of support surface.

[0024] 2. When the box needs to turn, the left / right belt drive motor starts, driving the universal ball on the first support surface above the left / right belt conveyor area to roll, thereby creating a speed difference between the universal ball in the left / right belt conveyor area and the universal ball in the non-left / right belt conveyor area on the first support surface, thereby driving the box to turn.

[0025] The beneficial effect of the utility model is: providing a double-track diverter, using a conveyor chain net and a left / right belt conveyor to replace the fixed sidewall / steering assembly / differential conveyor line of the prior art, and realizing the diversion of packaging boxes. Compared with the prior art, it has the following advantages:

[0026] 1. The impact cylinder on the side of the fast conveyor belt in the prior art is eliminated, solving a series of shortcomings and problems of the cylinder;

[0027] 2. The reversing components are eliminated, which does not affect the speed and rhythm of the box turning;

[0028] 3. The conveyor chain net ball bearings can be arranged as needed according to the shape characteristics of the packaging box. The ball bearings are placed on both sides of the bottom of the packaging box, and the middle of the packaging box is suspended above the conveyor chain net, which concentrates the friction force on both sides of the bottom of the packaging box, providing greater torque for the steering of the packaging box, thereby improving the steering speed of the box and the production rhythm.
