Description

Technical Field

[0001] This utility model relates to a device suitable for sorting square-shaped cigarettes, belonging to the technical field of cigarette sorting equipment. Background Technology

[0002] With the continuous development of the tobacco industry, many different sizes of non-standard cigarette cartons have emerged in the market to meet diverse consumer needs. Tobacco logistics and distribution centers need to sort cartons of cigarettes of different grades and quantities according to customer orders. Currently, the industry mainly uses vertical sorting machines to sort non-standard cigarette cartons. These machines primarily consist of a conveyor system, a vertical cigarette bin, and a striking mechanism. The conveyor system feeds the cigarette cartons into the vertical cigarette bin, and the striking mechanism at the bottom of the bin pushes the cartons out according to the order requirements. This pushing method uses the striking blocks of the striking mechanism to strike the side of the cigarette cartons, thus ejecting them; hence, it is also called an ejector-type sorting device. This sorting setup can sort most types of cigarettes, but it is not very effective for sorting a special square cigarette pack (120mm×80mm×50mm). The main reason is that when the current sorting mechanism ejects the cigarette pack, it strikes the short side of the pack, causing it to deviate during delivery, resulting in poor cigarette posture. Some packs even deviate at a large angle, causing them to be transported side by side with other cigarette packs, making it impossible to identify and code them later. Utility Model Content

[0003] The purpose of this invention is to provide a device suitable for sorting square-shaped cigarette packs. When the device ejects the cigarette packs, it strikes the long side of the pack, making it less prone to deflection during delivery and ensuring good cigarette posture.

[0004] The technical solution of this utility model is as follows: A device suitable for sorting square-shaped special-shaped cigarettes includes a frame, a conveying device on the frame, a first side cigarette pushing device at the end of the conveying device along its width direction, a vertical cigarette bin on the outside of the conveying device, the outlet end of the first side cigarette pushing device being connected to the inlet end of the vertical cigarette bin via a second cigarette pushing device, and a striking mechanism at the bottom of the vertical cigarette bin, the conveying direction of the striking mechanism being perpendicular to the length direction of the vertical cigarette bin.

[0005] In the aforementioned device for sorting square-shaped special cigarettes, the conveying device is formed by connecting multiple sequentially connected conveyor belts, wherein the tail end of the last conveyor belt is provided with a vertical baffle, and the last conveyor belt is also provided with a first side cigarette pushing device. Each conveyor belt section is provided with a set of detection switches at its end, and multiple sets of position detection switches are provided in front of the detection switches of the last conveyor belt.

[0006] In the aforementioned device for sorting square-shaped special-shaped cigarettes, side baffles are provided on both sides of the conveyor belt, and the connecting parts at the top of the side baffles are fixedly connected to the slide groove of the transverse mounting rod.

[0007] In the aforementioned device for sorting square-shaped special-shaped cigarettes, the head end of the conveying device is rotatably connected to a tipping bucket, and the bottom of the tipping bucket is connected to a cylinder.

[0008] In the aforementioned device for sorting square-shaped special-shaped smoke, the first side-pushing smoke device includes a first linear module arranged along the width direction of the conveying device, and a first smoke-pushing plate is connected to the slider of the first linear module.

[0009] In the aforementioned device for sorting square-shaped special-shaped cigarettes, the second cigarette pushing device includes an outer mounting frame and an inner mounting frame that are fixedly connected to the outer wall and inner wall of the vertical cigarette bin, respectively. A second cigarette pushing channel is formed between the outer mounting frame and the inner mounting frame. A second cigarette pushing plate is provided in the second cigarette pushing channel. A second linear module is provided along the length of the outer mounting frame. The slider of the second linear module is connected to the second cigarette pushing plate.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] An embodiment of this utility model: A device suitable for sorting square-shaped special-shaped smoke includes a frame, a conveying device 1 is provided on the frame, a first side smoke pushing device 2 is provided at the end of the conveying device 1 along its width direction, that is, the first side smoke pushing device 2 pushes smoke along the width direction of the conveying device 1, a vertical smoke chamber 3 is provided on the outside of the conveying device 1, the outlet end of the first side smoke pushing device 2 is connected to the inlet end of the vertical smoke chamber 3 through a second smoke pushing device 4, and a striking mechanism 5 is provided at the bottom of the vertical smoke chamber 3, the conveying direction of the striking mechanism 5 is perpendicular to the length direction of the vertical smoke chamber 3.

[0024] During operation, the entire box of square-shaped special-shaped cigarettes is placed on the conveyor 1 in the form of stacks (consisting of several rows and layers of cigarette packs). The length of the cigarette packs is aligned with the length of the conveyor 1. After the stacks are conveyed from the head to the tail of the conveyor 1, the first side-pushing device 2 activates, pushing the stacks from their long sides. One row of cigarette packs is pushed towards the outlet each time. The pushed-out cigarette packs enter the working area of ​​the second side-pushing device 4, which pushes them from their short sides, allowing the entire row of cigarette packs to enter the vertical cigarette bin 3, thus automatically replenishing the vertical cigarette bin 3. When sorting of the square-shaped special-shaped cigarettes is required, the striking mechanism 5 activates to send out the bottommost cigarette packs. Because the conveying direction of the striking mechanism 5 is perpendicular to the length of the vertical cigarette bin 3, the striking blocks on the striking mechanism 5 contact the long side of the cigarette packs, not the short side, during operation. This prevents the cigarette packs from tilting during delivery and ensures a better cigarette posture. This ensures that cigarette cartons are not sent out side-by-side with other cartons after sorting, making it easier to identify and code them later.

[0025] The conveying device 1 is formed by connecting multiple conveyor belts 101 in sequence. The tail of the last conveyor belt 101 is provided with a vertical baffle 102. The last conveyor belt 101 is also provided with a first side smoke pushing device 2. Each section of the conveyor belt 101 is provided with a set of detection switches 103 at the end. In front of the detection switches 103 of the last conveyor belt 101, there are multiple sets of position detection switches 104.

[0026] During the stacking and conveying of cigarettes, workers open the boxes of square-shaped special cigarettes and place the entire box on the conveyor belt 101. The stack of cigarettes is conveyed forward along the conveyor belt 101. The detection switch 103 on each section of the conveyor belt 101 is used to detect whether the stack of cigarettes has been conveyed to the correct position and whether there is any loose stacking. The reason for setting multiple conveyor belts 101 is that the first-side smoke-pushing device 2 at the end does not push out the entire stack of smoke at once during the smoke-pushing process, but pushes it out in multiple stages. The last conveyor belt 101 remains stopped until the first-side smoke-pushing device 2 pushes out the entire stack of smoke. Since the stacks of smoke are placed on the conveyor belt 101 manually, there will inevitably be a distance between adjacent stacks of smoke. If the entire conveyor device 1 is only a single conveyor belt 101, the entire conveyor belt 101 will have to stop when the first-side smoke-pushing device 2 is working. Only after the first-side smoke-pushing device 2 finishes pushing the smoke will the conveyor belt 101 transport the stacks of smoke to the position of the first-side smoke-pushing device 2. Transporting the stacks of smoke forward takes a certain amount of time, which will inevitably affect production efficiency. Therefore, the conveyor device 1 is set to be formed by connecting multiple sequentially connected conveyor belts 101. When the last conveyor belt 101 stops, the preceding conveyor belts 101 can continue to operate, continuously transporting the stacks of smoke forward, thereby shortening the distance between the stacks of smoke. A vertical baffle 102 is installed to prevent the stacked cigarettes from falling off the last conveyor belt 101 during forward transport. Multiple sets of position detection switches 104 are also installed in front of the detection switch 103 on the last conveyor belt 101. These position detection switches 104 detect whether the stacked cigarettes have been properly conveyed onto the last conveyor belt 101; once properly conveyed, the last conveyor belt 101 stops rotating. Since the square-shaped special-shaped cigarettes come in various sizes, multiple sets of position detection switches 104 are provided, with different position detection switches 104 corresponding to different sizes of square-shaped special-shaped cigarettes.

[0027] Side baffles 105 are provided on both sides of the conveyor belt 101. The connecting piece 106 at the top of the side baffle 105 is fixedly connected to the slide groove of the transverse mounting rod 107. The bolt passes through the slide groove on the transverse mounting rod 107 and extends into the threaded hole of the connecting piece 106, thereby locking and fixing the side baffle 105. The side baffles 105 on both sides and the conveyor belt 101 at the bottom form a conveying channel for stacked smoke. In order to accommodate square special-shaped smoke of different sizes, the width of the conveying channel should also be adjustable. During the adjustment process, the bolts can be loosened and the side baffles 105 can be moved.

[0028] Since the entire device has a certain height, a tipping bucket 6 is rotatably connected to the head end of the conveyor device 1. The tipping bucket 6 consists of a belt conveyor and three side plates. A cylinder 7 is connected to the bottom of the tipping bucket 6. When placing the stack of tobacco, the worker puts the unpacked stack of tobacco into the tipping bucket 6, and then pushes the tipping bucket 6 to rotate and lift it by the cylinder 7, so that the surface of the tipping bucket 6 is flush with the frontmost conveyor belt 101. Then the belt conveyor of the tipping bucket 6 works to send the stack of tobacco onto the frontmost conveyor belt 101. This structure makes it convenient for workers to place the stack of tobacco.

[0029] The first side smoke pushing device 2 includes a first linear module 201 arranged along the width direction of the conveying device 1. A first smoke pushing plate 202 is connected to the slider of the first linear module 201. The first smoke pushing plate 202 is driven to move linearly by the first linear module 201, thereby realizing the smoke pushing action.

[0030] The second smoke pushing device 4 includes an outer mounting frame 401 and an inner mounting frame 406, which are respectively fixedly connected to the outer wall 301 and the inner wall 302 of the vertical smoke chamber 3. The outer mounting frame 401 is fixedly connected to the outer wall 301, and the inner mounting frame 406 is fixedly connected to the inner wall 302. A second smoke pushing channel 402 is formed between the outer mounting frame 401 and the inner mounting frame 406. A second smoke pushing plate 403 is provided in the second smoke pushing channel 402. A second linear module 404 is provided along the length of the outer mounting frame 401. The slider of group 404 is connected to the second smoke pusher plate 403. The bottom of the second smoke pusher channel 402 is provided with a smoke pusher support plate 405. The surface of the smoke pusher support plate 405 is flush with the surface of the conveyor belt 101. During the smoke pusher process of the first side smoke pusher device 2, the cigarette packs are pushed into the second smoke pusher channel 402 and supported by the smoke pusher support plate 405. After the smoke pusher device 2 finishes pushing the cigarettes, the second linear module 404 drives the second smoke pusher plate 403 to move, pushing the entire column of cigarette packs from the second smoke pusher channel 402 into the vertical smoke chamber 3, realizing automatic smoke replenishment of the vertical smoke chamber 3.

[0031] Two vertical smoke chambers 3 are provided, respectively located at the left and right ends of the second smoke pushing device 4. The first side smoke pushing device 3 is located in the middle of the second smoke pushing device 4. The advantage of this arrangement is that during the automatic smoke replenishment of one of the vertical smoke chambers 3 by the second smoke pushing plate 403, the first side smoke pushing device 2 can push the next column of cigarettes into the second smoke pushing channel 402. When the second smoke pushing plate 403 moves in the reverse direction, it can push the newly replenished cigarettes into the other vertical smoke chamber 3, thereby improving the smoke replenishment efficiency.

[0032] The vertical smoke chamber 3 includes an outer chamber wall 301 and an inner chamber wall 302. A front and rear chamber wall 303 is also provided between the outer chamber wall 301 and the inner chamber wall 302. The outer chamber wall 301, the inner chamber wall 302, and the front and rear chamber walls 303 are all fixed on the outer mounting rod 304. The outer mounting rod 304 is fixed on the frame 1. The outer chamber wall 301 is directly connected to the outer mounting rod 304 by bolts. The inner chamber wall 302 is fixed with a fastener. The bolts extend from the groove of the outer mounting rod 304 and pass into the connecting hole of the fastener. When it is necessary to adjust the distance between the outer chamber wall 301 and the inner chamber wall 302 of the vertical smoke chamber 3 to accommodate different widths of cigarettes, the connecting bolts of the fastener are loosened to allow the inner chamber wall 302 to slide along the outer mounting rod 304. During the movement of the inner compartment wall 302, the inner mounting bracket 406, which is fixedly connected to it, will also move, thereby adjusting the width of the second smoke pushing channel 402. Adjusting rods 305 are connected to the back of the front and rear compartment walls 303. The adjusting rods 305 pass through adjusting blocks 306, which are slidably engaged with the outer mounting rod 304 via bolts. When adjusting the distance between the outer compartment wall 301 and the inner compartment wall 302, the positions of the front and rear compartment walls 303 also need to be adjusted accordingly. This can be done by adjusting the mounting position of the adjusting block 306 on the outer mounting rod 304. When the length of the cigarettes pushed into the vertical smoke compartment 3 changes, the length of the adjusting rod 305 extending from the adjusting block 306 can be adjusted to change the distance between the front and rear compartment walls, accommodating cigarettes of different lengths. The adjusting rod 305 can be locked in place by the locking screws on the adjusting block 306.

[0033] The head end of the striking mechanism 5 is connected to an inclined slide plate 8, which facilitates the transfer of sorted cigarette packs to other conveyor lines via the inclined slide plate 8. Side baffles 9 are provided on both sides of the surface of the inclined slide plate 8. The bottom of the side baffles 9 is provided with outwardly extending wing plates 10. The wing plates 10 are provided with long strip insertion holes 11. After the bolt passes through the long strip insertion holes 11, it is fixedly connected to the inclined slide plate 8. Loosening the bolts can move the side baffles 9 to accommodate cigarette packs of different sizes.

[0034] The striking mechanism 5 includes a transmission chain assembly 501. A cigarette support plate 502, extending above the top of the transmission chain assembly 501, is located on the outer side of the assembly. A side baffle 503 is also located above the support plate 502. An adjusting shaft 504 is connected to the back of the side baffle 503. The adjusting shaft 504 passes through an adjusting slider 505, which slidably engages with the groove of the outer mounting rod 304. A striking block 506 is mounted on the transmission chain assembly 501. The cigarettes at the bottom of the vertical cigarette compartment 3 fall onto the support plate 502, where they are supported. Because the support plate 502 extends above the transmission chain assembly 501, the transmission chain assembly 501 does not contact the surface of the cigarettes during rotation, preventing damage to the coating. The rotation of the transmission chain assembly 501 causes the striking block 506 to move, striking the long side of the cigarette and thus ejecting it. An adjusting shaft 504 is connected to the back of the side baffle 503. The adjusting shaft 504 passes through the adjusting slider 505. The adjusting slider 505 is slidably engaged with the groove of the outer mounting rod 304. By adjusting the length of the adjusting shaft 504 extending out of the adjusting slider 505, it can accommodate cigarettes of different lengths.
