Description

Technical Field

[0001] The utility model relates to a cigarette box turning device. Background Art

[0002] During the daily outbound operation of the finished product warehouse of the cigarette factory, the finished cigarette boxes are processed by the warehouse management system to generate orders, the shuttle car and conveyor are used to carry out the actual pallet outbound delivery of the cigarette boxes, the robots are depalletized, and the sorting line is used to pick them up. Then, they reach the telescopic belt, pass through the code scanning device and are loaded onto the truck to complete the outbound operation. Among them, there are two different sizes of cigarette boxes: regular cigarette boxes and slim cigarette boxes when the cigarette factory ships out of the warehouse. Regular cigarette boxes do not need to be turned after being depalletized, but the slim cigarette boxes are unstable during high-speed transportation because their short sides are parallel to the conveying direction after being depalletized, so they need to be turned. Therefore, it is necessary to provide a cigarette box steering device to rotate the direction of the slim cigarette boxes so that the slim cigarette boxes can be transported smoothly on the conveyor. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cigarette box steering device, the structural features of which are:

[0006] The cigarette box is transported from the back to the front by the conveyor, and the short side is parallel to the conveying direction. A turning position is set on the conveying path of the conveyor. The cigarette box turning device is arranged on the periphery of the conveyor, located at the turning position, and includes a rear detection photoelectric sensor, a front detection photoelectric sensor, a turning cylinder, a solenoid valve, a turning block, and a PLC. The rear detection photoelectric sensor, the front detection photoelectric sensor, and the turning cylinder are distributed in sequence from the back to the front on the same side of the conveyor. The rear detection photoelectric sensor and the front detection photoelectric sensor are used to detect the arrival signal of the passing cigarette box and feed it back to the PLC. The extension of the turning cylinder The retraction direction is perpendicular to the conveying direction and is set horizontally. The steering block is installed at the end of the cylinder rod. When retracted, the steering block is outside the conveying surface of the conveyor. When extended, the steering block is driven to translate in the left and right directions to overhang above the conveying surface, and the cigarette box passed by the steering block is pushed. When fully extended, the distance between the steering block and the outer edge of the conveying surface on the side where it is located is 1 / 3 of the width of the conveying surface. The solenoid valve matched with the steering cylinder is electrically connected to and controlled by the PLC. When the front detection photoelectric sensor has a signal and the rear detection photoelectric sensor has no signal, the PLC controls the extension of the steering cylinder through the solenoid valve.

[0007] The structural features of the utility model also lie in:

[0008] The conveyor is a roller conveyor.

[0009] The distance between the rear detection photoelectric sensor and the front detection photoelectric sensor along the conveying direction is set corresponding to the length of the short side of the cigarette box.

[0010] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0011] The utility model cooperates with a rear detection photoelectric sensor, a front detection photoelectric sensor and a steering cylinder equipped with a steering block, and sets the spacing between the rear detection photoelectric sensor and the front detection photoelectric sensor along the conveying direction in accordance with the length of the short side of the cigarette box. The rear detection photoelectric sensor and the front detection photoelectric sensor detect the arrival signal of the passing cigarette box. Based on this, the steering cylinder is used to drive the steering block to extend, and the steering block contacts the cigarette box, so that the cigarette box is turned to a certain extent, avoiding the cigarette box from participating in high-speed conveying with its short side completely parallel to the conveying direction, improving the conveying stability, and providing guarantee for the smooth progress of downstream operations.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The cigarette box is transported from back to front by conveyor 1, with the short side parallel to the conveying direction. A turning position is set on the conveying path of conveyor 1. Please refer to Figure 1 to Figure 2The cigarette box steering device of this embodiment is arranged on the periphery of the conveyor 1, at the steering position, and includes a rear detection photoelectric sensor 2, a front detection photoelectric sensor 3, a steering cylinder 4, a solenoid valve 5, a steering block 6, and a PLC 7. The rear detection photoelectric sensor 2, the front detection photoelectric sensor 3, and the steering cylinder 4 are arranged in sequence from the back to the front on the same side of the conveyor 1. The rear detection photoelectric sensor 2 and the front detection photoelectric sensor 3 are used to detect the arrival signal of the passing cigarette box and feed it back to the PLC 7. The extension direction of the steering cylinder 4 is perpendicular to the conveying direction and is arranged horizontally. The steering block 6 is installed at the end of the cylinder rod. When retracted, the steering block 6 is located outside the conveying surface of the conveyor 1. When extended, the steering block 6 is driven to translate in the left and right directions to overhang above the conveying surface, and the passing cigarette box is pushed by the steering block 6. When fully extended, the distance between the steering block 6 and the outer edge of the conveying surface on the side where it is located is 1 / 3 of the width of the conveying surface. The solenoid valve 5 matched with the steering cylinder 4 is electrically connected and controlled by the PLC 7. The PLC 7 When there is a signal from the front detection photoelectric sensor 3 and no signal from the rear detection photoelectric sensor 2, the steering cylinder 4 is extended through the solenoid valve 5.

[0017] In this embodiment:

[0018] The conveyor 1 is a roller conveyor.

[0019] The distance between the rear detection photoelectric sensor 2 and the front detection photoelectric sensor 3 along the conveying direction is set corresponding to the length of the short side of the cigarette box.

[0020] When cigarette factories are leaving the warehouse, there are two different sizes of cigarette boxes: regular cigarette boxes and slim cigarette boxes. After the slim cigarette boxes are unstackered, the short sides are parallel to the conveying direction, which will cause instability during high-speed conveying. The direction needs to be reversed to achieve stable high-speed conveying and provide guarantee for the smooth progress of downstream operations. The purpose of the cigarette box steering device of this embodiment is to make the slim cigarette box turn, and the working process is as follows:

[0021] The cigarette box is transported from back to front by the conveyor, passing through the rear detection photoelectric sensor and the front detection photoelectric sensor in turn. When the rear detection photoelectric sensor is triggered and the front detection photoelectric sensor is also triggered, the steering cylinder does not move. When only the front detection photoelectric sensor is triggered and the rear detection photoelectric sensor is not triggered, the PLC controls the steering cylinder to extend through the solenoid valve, driving the steering block to extend horizontally in the left and right directions, and contacting the adjacent part of the nearest cigarette box located upstream of the steering block with the steering block as the boundary. During this process, the cigarette box turns.

[0022] On the basis of this embodiment, the degree to which the slim cigarette aroma is diverted can be adjusted accordingly according to actual production needs by setting the extension time of the diverting block and the distance from the outer edge of the conveying surface on the side where the diverting block is fully extended.

[0023] As a further application of this embodiment, those skilled in the art may set the cigarette box steering device on a cigarette box sorting conveyor line to steer the conveyed slim cigarette boxes, thereby replacing the traditional operation mode that relies on manual steering, improving the degree of production automation, and providing guarantees for the subsequent transportation and sorting of cigarette boxes on the sorting line.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
