Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging production technology, and in particular to a detachable cigarette pack rejection device. Background Technology

[0002] During cigarette packaging production, equipment needs to be debugged for various reasons. During the debugging process, a certain number of cigarette packs produced need to be removed from the equipment for appearance quality verification. Statistical analysis of the appearance quality of the sampled cigarette packs is used to verify the current operating status of the equipment. Traditionally, operators manually remove the cigarette packs from the conveyor channel. Since the number of cigarette packs to be verified is large, operators need to continuously operate in the conveyor channel. Manually removing cigarette packs while the equipment is operating normally can easily create additional workload for the entire verification process, increasing the workload of the operators. In addition, some cigarette pack appearance quality issues are caused by improper handling during removal. Summary of the Invention

[0003] To address the above shortcomings, this utility model provides a detachable cigarette pack rejection device, which helps to automatically reject cigarette packs, reduce the workload of operators, improve the efficiency of equipment debugging, and does not affect normal production operations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A detachable cigarette pack rejection device includes a cigarette pack conveying channel, which has two layers, the height of which is equal to the width of the cigarette pack. A belt runs around the surface of the cigarette pack conveying channel to push the cigarette pack forward.

[0006] A cigarette pushing device is mounted on the cigarette pack conveying channel via a rotatable fixing device. The cigarette pushing device can be set perpendicularly or parallel to the conveying direction of the cigarette pack conveying channel. In the vertical setting state, the cigarette pushing device is inserted into the cigarette pack conveying channel. In the parallel setting state, the cigarette pushing device is disengaged from the cigarette pack conveying channel to ensure that the cigarette pack is conveyed normally within the cigarette pack conveying channel.

[0007] The smoke-pushing device includes a C-shaped bracket, with an active toothed roller and a driven toothed roller respectively installed at both ends of the C-shaped bracket; the active toothed roller is driven by a motor, which is fixed to the C-shaped bracket; a toothed belt is installed between the active toothed roller and the driven toothed roller; and a plurality of smoke-pushing blocks are installed on the toothed belt.

[0008] Optionally, the motor is a DC servo motor.

[0009] Optionally, the distance between two adjacent cigarette pushers is not less than the width of the cigarette pack conveying channel. Optionally, a fixing plate is also included, with its inner end fixed to the top surface of the cigarette pack conveying channel; one end of the C-shaped bracket is located at the outer end of the fixing plate via the rotatable fixing device. Optionally, the rotatable fixing device includes an elastic bolt, the upper part of which is movably positioned at the outer end of the fixing plate; a locking block is provided at the top of the elastic bolt; a first locking groove and a second locking groove are provided at the outer end of the fixing plate corresponding to the locking block; the first and second locking grooves are perpendicular to each other; the lower part of the elastic bolt is connected to the C-shaped bracket; under the elastic force of the elastic bolt itself, the upper part of the elastic bolt is continuously subjected to a downward pulling force, causing the locking block to be stably engaged in the first or second locking groove under tension.

[0010] Optionally, an automatic control device may also be included, which includes a proximity switch and a controller. The proximity switch is located behind the cigarette pusher and is used to monitor the position of the cigarette pack and control the operation of the motor through the controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The cigarette packs are automatically removed from the cigarette pack conveyor channel by pushers on a toothed belt. A proximity switch detects the approach of the cigarette packs, and a controller operates a DC servo motor to automatically remove them. The controller can adjust the motor speed and running time to ensure smooth removal. The running time control prevents the next pusher from entering the conveyor channel area, thus ensuring the normal removal of the next cigarette pack. The pusher's position is adjustable. When not in use, it can be rotated 90 degrees using elastic bolts to move it away from the conveyor channel without affecting normal cigarette pack transport. When needed, the pusher is rotated to enter normal operation. In both states, the position can be fixed using the elastic bolts and slots on the fixing plate. This invention achieves automatic cigarette pack removal, reducing operator workload, improving efficiency during equipment setup, and not affecting normal production operations.

[0023] A detachable cigarette pack rejection device includes a cigarette pack conveying channel 100, the cigarette pack conveying channel 100 includes upper and lower partitions 101, the height of the upper and lower partitions 101 is the width of the cigarette pack 103, and a belt 102 runs around the surface of the cigarette pack conveying channel to push the cigarette pack 103 forward.

[0024] The system includes a cigarette pushing device 200, which is mounted on the cigarette pack conveying channel 100 via a rotatable fixing device. In this embodiment, the following solution is adopted:

[0025] The system includes a fixing plate 209, the inner end of which is fixed to the top surface of the cigarette pack conveying channel 100 by fixing screws 205; it also includes a C-shaped bracket, which serves as a support frame, with a driving toothed roller 202 and a driven toothed roller 203 respectively at its two ends; a toothed belt 204 is provided between the driving toothed roller and the driven toothed roller; a plurality of cigarette pushers 201 are provided on the toothed belt 204, the cigarette pushers 201 being perpendicular to the toothed belt 204 and used to push the cigarette pack 103 out of the cigarette pack conveying channel 100 (pushing it out in a direction perpendicular to the conveying direction of the cigarette pack 103); the distance between two adjacent cigarette pushers is not less than the width of the cigarette pack conveying channel, thus preventing the adjacent cigarette pushers from stopping in the area of ​​the cigarette pack conveying channel 100 after the previous cigarette pack is pushed out, thereby preventing the normal pushing out of the next cigarette pack (the interval between cigarette packs conveyed in production is relatively long). The active toothed roller 202 is driven by a motor. In this embodiment, the motor is preferably a DC servo motor 302. The motor is fixed to the C-shaped bracket. In order to realize the rotatable adjustment of the C-shaped bracket (i.e., 90-degree adjustment), one end of the C-shaped bracket is provided on the outer end of the fixing plate 209 by a rotatable fixing device.

[0026] In order to enable the cigarette pushing device to be arranged perpendicularly or parallel to the conveying direction of the cigarette pack conveying channel, the following structure is adopted in this embodiment:

[0027] The rotatable fixing device includes an elastic bolt 206, the upper part of which is movably disposed on the outer end of the fixing plate 209 (i.e., the body of the elastic bolt 206 is rotatably connected to the fixing plate 209, and is locked and fixed by the elastic upper part of the elastic bolt 206); a locking block 207 is provided on the top of the elastic bolt 206; a first locking groove 208 and a second locking groove are provided on the outer end of the fixing plate 209 corresponding to the locking block 207; the first locking groove 208 and the second locking groove are arranged perpendicular to each other. The lower part of the elastic bolt 206 is connected to the C-shaped bracket. Under the elastic force of the bolt itself, the upper part of the bolt is constantly pulled downwards, causing the locking block 207 to be stably locked into the first locking groove 208 or the second locking groove. That is, when locked into the first locking groove 208, the cigarette pushing device is parallel to the conveying direction of the cigarette pack conveying channel. In the parallel setting state, the cigarette pushing device is disengaged from the cigarette pack conveying channel, ensuring that the cigarette pack is conveyed normally within the cigarette pack conveying channel. When locked into the second locking groove, that is, in the vertical setting state, the cigarette pushing device is inserted into the cigarette pack conveying channel. The advantage of this structure is that the elastic bolt 206 can be rotated after being manually pulled up. When the cigarette pushing device 200 is in working condition, the toothed belt 204 is perpendicular to the cigarette pack conveying channel 101, and the locking block 207 is fixed by the second locking slot. When not in use, the elastic bolt 206 is pulled up, and the cigarette pushing device rotates 90 degrees together, so that the toothed belt 204 is parallel to the cigarette pack conveying channel 101. At this time, the locking block 207 is inserted into the first locking slot 208 and fixed.

[0028] In use, the DC servo motor 302, controller 301, and proximity switch 303 are electrically connected. When the proximity switch 303 detects the cigarette pack 103, the controller 301 controls the DC servo motor 302 to run, and the active toothed roller 202 drives the toothed belt 204 to push the cigarette pack 103 out of the cigarette pack conveying channel 101 through the cigarette pusher block 201.
