Description

Technical Field

[0001] This utility model relates to the field of cigarette production and conveying technology, and in particular to a box-turning and turning device. Background Technology

[0002] In automated cigarette logistics systems, the automated sorting devices require cigarette cartons to be in the same position. However, during actual production and transportation, the cartons may be upright or lying flat, leading to inconsistencies during later stacking and making the stacks prone to collapse. Therefore, the posture of the cigarette cartons needs to be adjusted before stacking; otherwise, it will seriously affect the automated sorting process.

[0003] A search revealed a conveying device for automatically adjusting the posture of cigarette boxes, with publication number CN203246846U. The device includes a unit support, a motor, long rollers, short rollers, a tilting shaft, and a tilting frame. Long rollers are installed at both ends of the unit support and are driven by a drive motor. Although this solution can tilt the cigarette boxes, the boxes may tilt to one side of the conveyor belt during the conveying process and not be in the middle position. As a result, when the cigarette boxes enter the tilting frame, they are in an offset state, making them prone to falling off during the tilting process. This instability will affect the subsequent robot's grasping and palletizing. Utility Model Content

[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model discloses a cigarette box turning device. Cigarette boxes are transported to a central conveyor via a front conveyor belt. Under the action of inclined rollers on both sides, the dispersed cigarette boxes are concentrated in the middle, thus unifying their relative positions. Guided by guide rods on both sides, they smoothly enter the turning conveyor. Under the action of short rollers, the cigarette boxes are secured to the turning frame. A first sensor transmits a signal to a controller, which in turn controls the drive motor to rotate the shaft, causing the cigarette boxes to turn from an upright to a flat position. When the flat-lying cigarette boxes pass through the turning device, they encounter guide rollers and are turned under their guidance, ensuring the uniform shape of the cigarette boxes. This facilitates subsequent handling and stacking, effectively improving stacking quality and preventing collapse during stacking. It is characterized by strong practicality and wide applicability.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0019] See Figure 1-2 As shown, this utility model discloses a box-turning and turning device, including a conveying support 1. The conveying support 1 is equipped with a turning conveying device 2, a parallel conveying device 3, a centering conveying device 4, and a turning device 5. The centering conveying device 4 is located at the front end of the turning conveying device 2, and the turning device 5 is located on the parallel conveying device 3. The centering conveying device 4 includes two symmetrically arranged inclined roller groups 41 and guide rods 42. The guide rods 42 are located near one end of the turning conveying device 2. The turning conveying device 2 includes a rotating shaft 24, a drive motor 23, three rows of short roller groups 21, and two turning frames 22. A clearance groove 6 is formed between the three rows of short roller groups 21. The rotating shaft 24 is rotatably mounted on the conveying support 1. The turning frames 22 have an L-shaped structure and are arranged within the clearance grooves 6. The right angle of the turning frames 22 is connected to the rotating shaft 24. One end of the rotating shaft 24 is connected to the drive motor 23. Machine 23 is mounted on conveyor support 1 via mounting base. The cigarette boxes are transported to the central conveyor device 4 via the front conveyor belt. Under the action of the inclined roller group 41 on both sides, the cigarette boxes in the scattered positions are concentrated to the middle position, thereby unifying the relative position of the cigarette boxes. Then, under the action of the guide rods 42 on both sides, they can smoothly enter the turning conveyor device 2 in the center. Under the action of the short roller group 21, the cigarette boxes are stuck on the turning frame 22. The first sensor 7 transmits the signal to the controller, and the controller controls the drive motor to work. By rotating the rotating shaft 24, the cigarette boxes are turned, thereby changing the cigarette boxes from an upright position to a flat position. When the flat cigarette boxes pass through the turning device 5, they hit the guide roller 51 and turn under the guidance of the guide roller 51, thereby ensuring the uniform shape of the cigarette boxes, which is convenient for subsequent grabbing and stacking of the cigarette boxes, effectively improving the stacking quality and preventing collapse during the stacking process.

[0020] Specifically, the steering device 5 includes a support frame 52 and a guide roller 51. The support frame 52 is mounted on the conveying bracket 1, and the guide roller 51 is rotatably mounted on the extended end of the support frame 52. When the cigarette boxes are conveyed by the straight roller, the horizontally arranged cigarette boxes encounter the guide roller 51 and are turned under the obstruction and guidance of the guide roller 51, so that the cigarette boxes are in a vertical position, maintaining the uniform shape of the cigarette boxes, which is convenient for subsequent robot grasping.

[0021] Preferably, the support frame 52 has an "I" shaped structure to increase its supporting function. The support frame 52 is provided with a sliding groove 12. The support frame 52 is installed on the conveying bracket 1 by a screw. One end of the screw is connected to the conveying bracket 1, and the other end passes through the sliding groove 12. Nuts are provided on the screws on both the upper and lower sides of the support frame 52. By loosening the nuts, the extension distance of the support frame 52 can be adjusted to meet the needs of different models of cigarette boxes.

[0022] Furthermore, the adjacent rollers of the short roller groups 21 on both sides are driven by belts 11. The short roller groups 21 are driven by the parallel conveyor device 3 using belts 11. The transmission is stable and the short roller groups 21 on both sides drive the cigarette box to be conveyed.

[0023] Furthermore, the parallel conveying device 3 includes multiple straight rollers 31 arranged in parallel with each other and a conveying motor 32. The conveying motor 32 is mounted on the conveying support 1. One of the straight rollers 31 is connected to the output end of the conveying motor 32. The multiple straight rollers 31 are driven by belts 11. The conveying motor 32 drives the straight rollers 31 to move, thereby realizing the conveying of the tobacco box.

[0024] Furthermore, a first sensor 7 and a second sensor 8 are provided on the conveying bracket 1 on one side of the flipping conveyor 2. The first sensor 7 is used to sense that the cigarette box has arrived at the flipping frame 22 and transmits the signal to the controller. The controller controls the drive motor to work and rotates the rotating shaft 24 to flip the cigarette box, thereby changing the cigarette box from an upright position to a flat position. The second sensor 8 is used to detect that the cigarette box has left the flipping frame 22 and transmits the signal to the controller. The controller controls the drive motor to work and rotates the flipping frame 22 to reset it.

[0025] Furthermore, mounting grooves 9 are provided on both right-angled sides of the flipping frame 22. Multiple rollers 10 are arranged linearly on the mounting grooves 9. When the rollers 10 are slidably connected to the tobacco box, friction is reduced, making it easier for the tobacco box to leave the flipping frame 22.

[0026] In this embodiment, a cigarette box turning device is used such that the cigarette boxes are transported to the central conveyor 4 via a front conveyor belt. Under the action of the inclined roller groups 41 on both sides, the cigarette boxes in the scattered positions are concentrated to the middle position, thereby unifying the relative positions of the cigarette boxes. Then, under the action of the guide rods 42 on both sides, the cigarette boxes can smoothly enter the turning conveyor 2 in the center. Under the action of the short roller group 21, the cigarette boxes are stuck on the turning frame 22. The first sensor 7 transmits a signal to the controller, which controls the drive motor to work. By rotating the rotating shaft 24, the cigarette boxes are turned, thereby changing the cigarette boxes from an upright position to a flat position. When the flat cigarette boxes pass through the turning device 5, they hit the guide rollers 51 and turn under the guidance of the guide rollers 51, thereby ensuring the uniform shape of the cigarette boxes. This facilitates the subsequent handling and stacking of the cigarette boxes, effectively improving the stacking quality and preventing collapse during the stacking process. This utility model discloses a box-flipping and turning device that can stably flip and turn cigarette boxes, so that the cigarette boxes are in a uniform shape, ensuring the quality of subsequent stacking. It is convenient to use and highly practical.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
