Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to an automatic positioning and conveying device for tobacco boxes. Background Technology

[0002] Currently, during the conveying process of cigarette boxes, the boxes need to be rotated at a certain angle to facilitate inspection by staff. If manual conveying is used, it will not only reduce production efficiency and increase the labor intensity of workers, but also require workers to constantly move the boxes back and forth due to the short distance, increasing the processing waiting time for subsequent processes. Furthermore, it is not conducive to the establishment of automated production lines, resulting in reduced production efficiency.

[0003] In the actual operation of reversing the smoke boxes, it was found that although the reversing rod could achieve the reversing effect, after the smoke box made contact with the reversing rod, it would move a short distance away from the worker. This required the worker to pull the smoke box back a short distance by hand before they could hold it and check the quantity and adhesive quality. This not only increased the workload and labor intensity of the workers, but also, due to the limited width of the multiple supports, there was a risk that the smoke box might move off the conveyor shaft and conveyor rollers, which could cause the smoke box to fall and reduce the overall production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic positioning and conveying device for cigarette boxes, so as to solve the technical problems mentioned in the background art, such as the large space occupation of existing cigarette box conveying mechanisms, the inconvenience for employees to grab cigarette boxes for inspection, and the easy movement of cigarette boxes out of the conveying mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cigarette box positioning and conveying device, comprising a first conveying mechanism and a second conveying mechanism. The first conveying mechanism includes a first support, on which a plurality of conveying shafts are disposed. The second conveying mechanism includes a second support, on which a plurality of conveying rollers are disposed. A fixed box located below the conveying rollers is disposed on the second support. A movable reversing rod is disposed inside the fixed box. The top of the reversing rod extends upward to a certain height above the conveying rollers and is located between any two conveying rollers near the first support.

[0006] Preferably, a sliding groove is provided inside the fixed box, a moving block is slidably provided in the sliding groove, the moving block is rotatably connected to the reversing rod, the extension direction of the sliding groove is consistent with the axial direction of the conveying roller, and a flexible pad is fixedly provided on the outer surface of the reversing rod.

[0007] Preferably, an elastic element is provided in the sliding groove between the moving block and the side wall of the sliding groove.

[0008] Preferably, the second bracket is rotatably provided with a lead screw, and the second bracket is provided with a plurality of guide rods on the same horizontal plane as the lead screw. Two sliding rods are provided on the plurality of guide rods, and the fixed box is fixedly connected to one of the sliding rods.

[0009] Preferably, the front and rear sides of the lead screw have opposite directions of rotation, and the two sliding rods are respectively threaded to the front and rear sides of the lead screw.

[0010] Preferably, one end of the lead screw extends out of the second bracket and is provided with a rotating handle.

[0011] The beneficial effects of this utility model are:

[0012] 1. The cigarette box is conveyed by a set conveyor roller and conveyor shaft, and contacts the cigarette box at a specific ratio through a reversing rod. Utilizing the inertia of the cigarette box and the transmission of the conveyor shaft and conveyor roller, the cigarette box can deflect within a certain angle range, thus facilitating worker inspection of the cigarette box, reducing the workload and labor intensity of workers, and effectively improving the production efficiency of subsequent processes. By rotating the reversing rod on the moving block and sliding the moving block in the sliding groove, when the cigarette box contacts the reversing rod, the cigarette box changes angle but will not move away from the second conveying mechanism due to the reaction force of the reversing rod. Therefore, when the cigarette box moves to the first conveying mechanism, the worker can directly lift the cigarette box for inspection, further reducing the workload and labor intensity of workers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Currently, during the conveying process of cigarette boxes, the boxes need to be rotated at a certain angle to facilitate inspection by staff. If manual conveying is used, it will not only reduce production efficiency and increase the labor intensity of workers, but also require workers to constantly move the boxes back and forth due to the short distance, increasing the processing waiting time for subsequent processes. Furthermore, it is not conducive to the establishment of automated production lines, resulting in reduced production efficiency.

[0021] To resolve the above technical issues, please refer to Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic cigarette box positioning and conveying device, comprising a first conveying mechanism 1 and a second conveying mechanism 2. The first conveying mechanism 1 includes a first support 101, on which a plurality of conveying shafts 102 are mounted. The second conveying mechanism 2 includes a second support 201, on which a plurality of conveying rollers 202 are mounted. A fixed box 203 located below the conveying rollers 202 is mounted on the second support 201. A movable reversing rod 204 is provided inside the fixed box 203. The top of the reversing rod 204 extends upward to a certain height above the conveying rollers 202 and is located near the first support 102. Between any two conveying rollers 202 of the frame 101, a flexible pad 212 is fixedly provided on the outer surface of the reversing rod 204. A lead screw 208 is rotatably provided on the second bracket 201. Multiple guide rods 209 are provided on the second bracket 201 on the same horizontal plane as the lead screw 208. Two sliding rods 210 are provided on the multiple guide rods 209. The fixed box 203 is fixedly connected to one of the sliding rods 210. The front and rear sides of the lead screw 208 have opposite rotation directions. The two sliding rods 210 are respectively threaded to the front and rear sides of the lead screw 208. One end of the lead screw 208 extends out of the second bracket 201 and is provided with a handle 211.

[0022] In use, the cigarette box is conveyed from other processes to the conveyor roller 202 of the second conveying mechanism 2. Then the conveyor roller 202 rotates and drives the cigarette box to move closer to the first conveying mechanism 1. When the cigarette box moves to the position of the reversing rod 204, since the contact position between the flexible pad 212 and the reversing rod 204 and the cigarette box is within a limited range far from the center line of the cigarette box, this position is calculated in advance. This technology is existing technology and will not be described in detail here. The cigarette box deflects to a certain extent under the action of inertia, and the reversing rod 204 rotates to a certain extent. The rotation of the reversing rod 204 can also be driven by existing drive mechanisms (such as motors), making the rotation of the reversing rod 204 easy to control.

[0023] Subsequently, the cigarette box continues to deflect under inertia and comes into contact with the reversing rod 204 during this process. Under the rotation of the conveying roller 202, the cigarette box continues to move closer to the first conveying mechanism 1. The contact position between the cigarette box and the reversing rod 204 is divided into two sides. The wider side continues to move closer to the first conveying mechanism 1 and deflects, while the narrower side deflects in the opposite direction, resulting in a deflection of nearly 90 degrees and entering the conveying shaft 102 of the first conveying mechanism 1.

[0024] Subsequently, the cigarette box is conveyed to the next process for sorting under the action of the conveyor shaft 102. The rotation of the conveyor shaft 102 and the conveyor roller 202 is generally driven by the inertia of the previous process that transported the cigarette box to the second conveyor mechanism 2 and the first conveyor mechanism 1. Alternatively, the conveyor shaft 102 and the conveyor roller 202 can be driven by a motor. This technology is existing technology and will not be described in detail here.

[0025] The lead screw 208 is threadedly connected to the sliding rod 210. When the size of the cigarette box is different, the rotating handle 211 is turned so that the lead screw 208 drives the sliding rod 210 to slide on the guide rod 209, thereby causing the reversing rod 204 to move along the axial direction of the conveying roller 202. Thus, when the size of the cigarette box is different, the reversing rod 204 can always be in contact with a specific position of the cigarette box. This specific position is a range value. The specific position is obtained by existing technology and can also be obtained through multiple actual verifications, which will not be described in detail here. The inertia of the cigarette box and the transmission of the conveying roller 202 are used to make the cigarette box deflect at an angle.

[0026] The smoke box is conveyed by the conveying rollers 202 and the conveying shaft 102. The reversing rod 204 contacts the smoke box at a specific ratio. By utilizing the inertia of the smoke box and the transmission of the conveying shaft 102 and the conveying rollers 202, the smoke box can be deflected within a certain angle range, which makes it easier for workers to inspect the smoke box, reduces the workload and labor intensity of workers, and effectively improves the production efficiency of subsequent processes.

[0027] Example 2

[0028] In the actual operation of reversing the cigarette box, it was found that although the reversing rod 204 can achieve the reversing effect, after the cigarette box contacts the reversing rod 204 and reverses, it will move a small distance away from the worker. This requires the worker to pull it back by hand before they can hold the cigarette box to check the quantity and adhesive quality. This not only increases the workload and labor intensity of the workers, but also, due to the limited width of the multiple supports, the cigarette box may move out of the conveyor shaft 102 and conveyor roller 202, which may cause the cigarette box to fall and reduce the overall production efficiency.

[0029] Please see Figures 1 to 4 As shown, the technical solution adopted includes a fixed box 203, a sliding groove 205 is provided in the fixed box 203, a moving block 206 is slidably provided in the sliding groove 205, the moving block 206 is rotatably connected to the reversing rod 204, the extension direction of the sliding groove 205 is consistent with the axial direction of the conveying roller 202, and an elastic element 207 is provided in the sliding groove 205 between the moving block 206 and the side wall of the sliding groove 205.

[0030] Based on the above embodiments, during use, when the cigarette box contacts the reversing rod 204, the reversing rod 204 first rotates at a certain angle on the moving block 206, and the cigarette box moves as a whole towards the first conveying mechanism 1. At the same time, under the action of inertia and the conveying roller 202, the side of the cigarette box that is not in contact with the reversing rod 204 deflects, and then drives the reversing rod 204 to generate friction under the action of the cigarette box's movement force, causing the flexible pad 212 and the reversing rod 204 to rotate in opposite directions. At the same time, due to the deflection of the cigarette box at a certain angle, part of the inertial force pushes the reversing rod 204 and the moving block 206 to move along the sliding groove 205 towards the edge of the second support 201, thereby compressing the elastic element 207, so that the distance the cigarette box moves to the other edge due to inertia is smaller, thus preventing the cigarette box from moving out of the second support 201 when the inertia is large.

[0031] Meanwhile, as the distance the cigarette box moves away from the reversing rod 204 on the second support 201 becomes smaller, the distance between the cigarette box and the employee when it is transferred to the first support 101 and the conveyor shaft 102 becomes smaller. This means that the employee does not need to pull the cigarette box back, or only needs to pull it slightly and lift it to inspect the cigarette box, thus reducing the workload and labor intensity of the employee.

[0032] By rotating the reversing rod 204 on the moving block 206 and sliding the moving block 206 in the sliding groove 205, when the cigarette box contacts the reversing rod 204, the cigarette box will not move away from the second conveying mechanism 2 due to the reaction force of the reversing rod 204 while changing angle. As a result, when the cigarette box moves to the first conveying mechanism 1, the employee can directly lift the cigarette box for inspection, reducing the workload and labor intensity of the employee.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
