Description

Technical Field

[0001] The utility model relates to the technical field of cigarette pack production, in particular to a cigarette pack conveying and turning device. Background Art

[0002] The cigarette pack flipping part in the existing packaging machine is mainly controlled by a stepper motor. In the process of cigarette packs being wrapped into strips by strip box wrapping paper, the cigarette packs are accelerated by the pressure roller on the conveyor belt and enter the stepping flipping mechanism driven by the stepper motor in the manner of the rear pack pushing the front pack, so that the cigarette packs are upright. After the flipping is completed, they are then pushed into the packaging area by two cylinders for strip box packaging.

[0003] Since the flap of the stepping flip mechanism is often squeezed by cigarette packs, the stopping position of the flap will deviate from the original position, so that the newly pushed cigarette packs cannot enter the flap of the flip mechanism, causing cigarette pack blockage. Sometimes the cigarette packs will hit the flip mechanism flap, causing the cigarette packs to get stuck and fail to flip.

[0004] There is also a cigarette pack flipping and pushing device as described in application number 201921931900.2, which uses a curved slide rail so that the cigarette pack can be pushed by a reciprocating motion device when it reaches the end of the slide rail, and then the cigarette pack is erected, which facilitates the packaging of the cigarette pack. The whole process is smooth, avoiding the phenomenon of cigarette pack blockage that is prone to occur in traditional cigarette pack flipping devices. However, the curved slide rail in the device needs to be set longer to ensure low-friction transportation of the cigarette pack on the curved slide rail, which will undoubtedly increase the footprint of the device, and when the cigarette pack rises to the top of the curved slide rail, it still needs to rely on the mutual squeezing between the cigarette packs, which can easily cause squeezing and friction damage to the cigarette pack. Summary of the Invention

[0005] In order to solve the problem that the existing cigarette pack conveying and turning device is prone to cigarette pack blockage or cigarette pack friction damage, the utility model provides a new cigarette pack conveying and turning device.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A cigarette pack conveying and flipping device comprises a conveying plate and a flipping assembly. The top surface of the conveying plate is provided with a conveying groove adapted to the cigarette pack, and the flipping assembly is located on the output direction side of the conveying plate; the flipping assembly comprises two fixed support brackets symmetrically distributed front and back, a stepper motor whose rotating shaft is axially arranged front and back, a baffle, and a magnet block. A rotating rod is rotatably fixed between the top ends of the two fixed support brackets, the stepper motor is fixed to a side of the top end of one of the fixed support brackets away from the other fixed support bracket, the rotating shaft of the stepper motor is coaxially fixedly connected to the rotating rod, the outer sleeve of the rotating rod has a rotating cylinder with a tetrahedral outer circumference, and flipping blocks are fixed on all four sides of the rotating cylinder. One side surface of each flipping block is provided with a flipping groove adapted to the conveying groove on the conveying plate, and one end of each flipping block close to the rotating cylinder is provided with a A discharge port that provides a descending channel for the flipped cigarette packs, and a retreat chamber is provided in the other end of each flipping block away from the rotating cylinder. When the flipping block is in a horizontal state, a vertically arranged adsorption plate that can be adsorbed by the magnet block is installed in the retreat chamber of the flipping block for sliding left and right. A sliding plate hole is provided at one end of the flipping block close to the rotating cylinder, and a baffle is sliding left and right on the side of the discharge port close to the flipping groove, and the end of the baffle away from the rotating cylinder is fixedly connected to one side of the adsorption plate through the sliding plate hole. A spring is fixed between the other side of the adsorption plate and the side wall of the corresponding retreat chamber away from the adsorption plate. The magnet block is located on the right side of the flipping block rotated to the right, and the two ends of the magnet block are fixedly connected to the two fixed support brackets through two connecting brackets respectively. A rotation gap is provided between the magnet block and the other side of the flipping block away from the rotating cylinder.

[0008] When in use, the cigarette packs are squeezed and transported to the flip groove of the flip block in sequence along the conveying groove on the conveying plate until the cigarette packs enter the discharge port of the flip block rotated to the upper part and contact its baffle. Then the stepper motor is started (the single stroke of the stepper motor is set to a quarter of a turn). The stepper motor automatically turns off after working one stroke. During the operation of the stepper motor, the stepper motor drives the rotating rod to rotate 90 degrees, and the rotating rod drives the rotating cylinder to rotate 90 degrees. The flip block located on the left rotates 90 degrees, thereby causing the cigarette pack to flip 90 degrees. At the same time, the flip block originally located on the upper part also rotates 90 degrees. At this time, due to the action of the magnet block, the adsorption plate is adsorbed by the magnet block, and the adsorption plate squeezes the spring. At the same time, the adsorption plate drives the baffle to separate from the discharge port. The flipped cigarette pack passes through the discharge port and descends into the subsequent packaging. Then the stepper motor enters the next stroke, causing the flip block originally located on the right to separate from the position of the magnet block, and the corresponding spring recovers, thereby pushing the adsorption plate to reset, and the baffle blocks the discharge port, facilitating normal conveying of the cigarette packs.

[0009] Furthermore, there are multiple springs in each retreat cavity, and the multiple springs are evenly distributed in the corresponding retreat cavity front and back.

[0010] The device further includes a guide assembly comprising four U-shaped guide frames adapted to fit the cigarette packs. These frames are fixed to the other side of the four flip blocks, corresponding to the flip grooves on the flip blocks. The openings of the four U-shaped guide frames face the flip blocks, and the two side arms of each U-shaped guide frame are arranged in a front-to-back direction. The guide cylinder structure improves the stability of the vertical descent of the flipped cigarette packs.

[0011] Furthermore, the guide assembly also includes an adjustment plate, which is located inside the U-shaped guide frame and arranged parallel to the middle arm of the U-shaped guide frame. An adjustment screw is vertically fixed to the middle portion of a side surface of the adjustment plate near the middle arm of the U-shaped guide frame. The adjustment screw passes through the corresponding middle arm of the U-shaped guide frame and is screwed onto an adjustment nut. Guide rods are vertically fixed to the front and rear ends of the side surface of the adjustment plate near the middle arm of the U-shaped guide frame. Both guide rods pass through the corresponding middle arm of the U-shaped guide frame. The position of the adjustment plate is adjusted by adjusting the nut, the adjustment screw, and the two guide rods to accommodate the stable vertical descent of cigarette packs of varying thicknesses.

[0012] Furthermore, a guide plate is provided at one end of the adjustment plate close to the rotating cylinder, which is inclined and extends in a direction away from the corresponding flipping block, so as to further facilitate the smooth vertical descent of the flipped cigarette pack.

[0013] The beneficial effects produced by the present invention are as follows: the cigarette pack conveying and turning device described in the present invention realizes the vertical turning of the cigarette pack, ensures the vertical unloading of the cigarette pack, achieves the purpose of turning the cigarette pack, and effectively avoids the blockage and wear of the cigarette pack, providing reliable guarantee for the smooth production of cigarette packs.

Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 、 2As shown in FIG4 , a cigarette packet conveying and flipping device comprises a conveying plate 1 and a flipping assembly. The top surface of the conveying plate 1 is provided with a conveying trough 2 adapted to the cigarette packet 23, and the flipping assembly is located on the output direction side of the conveying plate 1; the flipping assembly comprises two fixed support brackets 3 symmetrically distributed front and back, a stepping motor 4 whose rotating shaft is axially arranged front and back, a baffle 12, and a magnet block 14. A rotating rod is rotatably fixed between the top ends of the two fixed support brackets 3, the stepping motor 4 is fixed to a side of the top end of one of the fixed support brackets 3 away from the other fixed support bracket 3, the rotating shaft of the stepping motor 4 is coaxially fixedly connected to the rotating rod, the outer sleeve of the rotating rod has a rotating cylinder 5 whose outer peripheral surface is a tetrahedron, and flipping blocks 6 are fixed on all four sides of the rotating cylinder 5. Each flipping block 6 is provided with a flipping groove 7 adapted to the conveying trough 2 on the conveying plate 1 on one side surface, and each flipping block 6 is provided with a flipping groove 7 adapted to the conveying trough 2 on the conveying plate 1 on one end thereof close to the rotating cylinder 5. A discharge port 8 of a descending channel is provided, and a retreat chamber 9 is provided in the other end of each flip block 6 away from the rotating cylinder 5. When the flip block 6 is in a horizontal state, a vertically arranged adsorption plate 10 that can be adsorbed by the magnet block 14 is installed in the retreat chamber 9 of the flip block 6 for sliding left and right. A sliding plate hole 11 is provided at one end of the flip block 6 close to the rotating cylinder 5. The baffle 12 slides left and right on the side of the discharge port 8 close to the flip groove 7 and the end of the baffle 12 away from the rotating cylinder 5 passes through the sliding plate hole 11 and is fixedly connected to one side of the adsorption plate 10. A spring 13 is fixed between the other side of the adsorption plate 10 and the side wall of the corresponding retreat chamber 9 away from the adsorption plate 10. The magnet block 14 is located on the right side of the flip block 6 rotated to the right, and the two ends of the magnet block 14 are fixedly connected to the two fixed support brackets 3 through two connecting brackets 15 respectively. A rotation gap 16 is provided between the magnet block 14 and the other side of the flip block 6 away from the rotating cylinder 5.

[0027] During use, the cigarette pack 23 is squeezed and conveyed in sequence along the conveying groove 2 on the conveying plate 1 to the turning groove 7 of the turning block 6, until the cigarette pack 23 enters the discharge port 8 of the turning block 6 rotated to the upper part and contacts its baffle 12, and then the stepper motor 4 is started (the single stroke of the stepper motor 4 is set to be a quarter of a circle), and the stepper motor 4 automatically turns off after working for one stroke. During the working process of the stepper motor 4, the stepper motor 4 drives the rotating rod to rotate 90 degrees, and the rotating rod drives the rotating cylinder 5 to rotate 90 degrees, and the turning block 6 located on the left rotates 90 degrees, thereby causing the cigarette pack 23 to turn 90 degrees. At the same time, the flip block 6 originally located at the top also rotates 90 degrees. At this time, due to the action of the magnet block 14, the adsorption plate 10 is adsorbed by the magnet block 14, and the adsorption plate 10 squeezes the spring 13. At the same time, the adsorption plate 10 drives the baffle 12 to separate from the discharge port 8. The flipped cigarette pack 23 passes through the discharge port 8 and then descends to enter the subsequent packaging. Then the stepper motor 4 enters the next stroke, so that the flip block 6 originally located on the right is separated from the position of the magnet block 14, and the corresponding spring 13 is restored, thereby pushing the adsorption plate 10 to reset, and the baffle 12 blocks the discharge port 8, which is convenient for the normal transportation of the cigarette pack 23.

[0028] In a specific implementation, there are multiple springs 13 in each retreat cavity 9 , and the multiple springs 13 are evenly distributed in the corresponding retreat cavity 9 front and back.

[0029] When implementing it specifically, Figure 1 、 3 As shown, the device also includes a guide assembly comprising four U-shaped guide frames 17, each adapted to fit the cigarette pack 23. The four U-shaped guide frames 17 are fixed to the other side of the four flip blocks 6, corresponding to the flip grooves 7 thereon. The openings of the four U-shaped guide frames 17 face the four flip blocks 6, and the two side arms of each U-shaped guide frame 17 are arranged front to back. The guide cylinder structure improves the stability of the vertical descent of the flipped cigarette pack 23.

[0030] When implementing it specifically, Figure 5 As shown, the guide assembly also includes an adjustment plate 18, which is located inside the U-shaped guide frame 17 and arranged parallel to the middle arm of the U-shaped guide frame 17. An adjustment screw 19 is vertically fixed to the middle portion of the side of the adjustment plate 18 near the middle arm of the U-shaped guide frame 17. The adjustment screw 19 passes through the corresponding middle arm of the U-shaped guide frame 17 and is screwed onto an adjustment nut 20. Guide rods 21 are vertically fixed to the front and rear ends of the side of the adjustment plate 18 near the middle arm of the U-shaped guide frame 17. Both guide rods 21 pass through the corresponding middle arm of the U-shaped guide frame 17. The position of the adjustment plate 18 is adjusted by adjusting the nut 20, the adjustment screw 19, and the two guide rods 21 to accommodate the stable vertical descent of cigarette packs 23 of varying thicknesses.

[0031] In specific implementation, a guide plate 22 is extended obliquely from one end of the adjustment plate 18 close to the rotating cylinder 5 in a direction away from the corresponding flipping block 6, so as to further facilitate the smooth vertical descent of the flipped cigarette pack 23.
