Description

Technical Field

[0001] This utility model relates to the field of cigarette pack appearance inspection technology, and in particular to an energy-saving cigarette pack separation device. Background Technology

[0002] During the cigarette packaging process of the GDH1000 packaging machine, in order to inspect the quality of the cigarette packs packaged by the GDH1000 packaging machine, a conveyor channel for inspecting the appearance of the cigarette packs is usually installed between the GDH1000 packaging machine and the cigarette box station. When the cigarette packs packaged by the GDH1000 packaging machine are sent to the inspection instrument on the conveyor channel to detect defects in the appearance of the cigarette packs, the inspection instrument will perform an appearance inspection on the passing cigarette packs. If a defective cigarette pack is detected, it will remind the worker to remove it in time or remove it from the cigarette pack removal station located downstream of the inspection instrument. If no defective cigarette pack is detected, the conveyor channel will continue to transport the cigarette packs to the cigarette box station for boxing.

[0003] The above-mentioned method involves adding a conveyor channel for inspecting the appearance of cigarette packs between the GDH1000 packaging machine and the cigarette box station. While this can remove defective cigarette packs from the conveyor channel to some extent, the following drawbacks exist in actual use: Because the conveyor channel for inspecting cigarette packs has a corner, when the GDH1000 packaging machine is operating at a high speed, the speed of the small cigarette packs slows down at the corner, causing them to stick together. Consequently, when these tightly packed cigarette packs are conveyed to the defect detection instrument in the conveyor channel, the instrument cannot detect the areas where the packs are stuck together, leading to false rejections. This not only increases the scrap rate of cigarette pack forming but also increases the consumption of auxiliary materials and raises the cost of cigarette production.

[0004] Therefore, it is necessary to improve and design the structure used to detect defects in cigarette packs, in order to solve the problem that the imaging detection device has a high false rejection rate at the corner of the conveyor channel because the cigarette packs are tightly attached to each other, resulting in a high scrap rate of cigarette pack forming, high consumption of auxiliary materials, and increased cigarette production costs. Utility Model Content

[0005] The purpose of this invention is to propose an energy-saving cigarette pack separation device to solve the problem that small cigarette packs are stuck together at the corner of the conveying channel, resulting in a high false rejection rate of the imaging detection device, leading to a high scrap rate of cigarette pack forming, high consumption of auxiliary materials, and increased cigarette production costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An energy-saving tobacco pack separation device includes:

[0008] The tobacco pack conveying channel has corners.

[0009] A cigarette pack cornering pneumatic conveyor includes a first pneumatic conveyor and a second pneumatic conveyor. The first pneumatic conveyor and the second pneumatic conveyor are respectively set on the inner side wall at the corner. The first pneumatic conveyor is located upstream of the second pneumatic conveyor. The first pneumatic conveyor and the second pneumatic conveyor are used together.

[0010] The cigarette pack appearance inspection component is located downstream of the second air conveyor. The cigarette pack appearance inspection component is set at the first notch on the side wall of the cigarette pack conveying channel, and the inspection end of the cigarette pack appearance inspection component passes through the first notch and faces into the cigarette pack conveying channel.

[0011] The defective cigarette pack rejection component is located downstream of the cigarette pack appearance inspection component. It is positioned at the second notch on the side wall of the cigarette pack conveying channel. The cigarette pack appearance inspection component is connected to the defective cigarette pack rejection component via a controller.

[0012] Preferably, the first air delivery component includes a first air pipe, a first regulating air valve, and a first air outlet; the first air outlet is opened on one of the inner side walls of the corner, the blowing end of the first air outlet faces the inside of the tobacco pack conveying channel, the air inlet end of the first air outlet is connected to the air outlet end of the first regulating air valve on the outer wall of the corner of the tobacco pack conveying channel, and the first regulating air valve is connected to the air delivery end of the first air compressor on the ground through the first air pipe.

[0013] Preferably, the first vent is inclined.

[0014] Preferably, the second air delivery component includes a second air pipe, a second regulating air valve, and a second air outlet; the second air outlet is located downstream of the first air outlet, and the second air outlet is opened on another inner side wall at the corner, with the blowing end of the second air outlet facing into the tobacco pack conveying channel, the air inlet end of the second air outlet being connected to the air outlet end of the second regulating air valve on the outer wall of the corner of the tobacco pack conveying channel, and the second regulating air valve being connected to the air delivery end of the second air compressor on the ground through the second air pipe.

[0015] Preferably, the second vent is inclined.

[0016] Preferably, the cigarette pack appearance inspection component is an appearance imaging inspection instrument. The appearance imaging inspection instrument has an inspection head that passes through a first notch on the side wall of the cigarette pack conveying channel and faces into the cigarette pack conveying channel. The bottom of the appearance imaging inspection instrument is connected to the top of the support plate, and the side wall of the support plate is connected to the side wall of the cigarette pack conveying channel at the first notch.

[0017] Preferably, the defective cigarette pack rejection component includes a gas collecting plate, a third air hole, and a third air pipe; the gas collecting plate is located downstream of the appearance imaging detector, and is set at the second notch on the side wall of the cigarette pack conveying channel. The gas collecting plate has a third air hole facing the surface wall inside the cigarette pack conveying channel. The third air hole communicates with the air cavity in the gas collecting plate. The air cavity in the gas collecting plate is also connected to the air outlet of the third air pipe connected to the surface wall away from the cigarette pack conveying channel. The air inlet of the third air pipe is connected to a third air compressor on the ground.

[0018] Preferably, an energy-saving cigarette pack separation device further includes a defective cigarette pack storage frame, which is disposed on another cigarette pack conveying channel sidewall corresponding to the sidewall of the cigarette pack conveying channel with a gas collecting plate. The defective cigarette pack storage frame is flush with a third notch on the sidewall of the other cigarette pack conveying channel, and the third notch is connected to the inside of the cigarette pack conveying channel.

[0019] During operation, when cigarette packs packaged by the GDH1000 packaging machine are conveyed to a corner of the conveyor channel and become stuck together, a first air-feeding component located near the exit end of the corner blows air onto the side wall of one cigarette pack, and a second air-feeding component located near the exit end of the corner blows air onto the side wall of the other cigarette pack. In this coordinated air-feeding action, the tightly stuck cigarette packs at the corner are separated, and the separation... The separated cigarette packs quickly pass through the corner of the conveyor channel. Then, the separated cigarette packs that have passed through the corner of the conveyor channel continue to be conveyed to the cigarette pack appearance inspection unit. The cigarette pack appearance inspection unit then inspects the appearance of the passing cigarette packs. If the cigarette pack appearance inspection unit detects a defective cigarette pack, the defective cigarette pack rejection unit located downstream of the cigarette pack appearance inspection unit removes the cigarette pack from the conveyor channel. If the cigarette pack appearance inspection unit does not detect a defective cigarette pack, it is conveyed to the cigarette packing station for subsequent boxing.

[0020] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0021] This invention involves placing a first air conveyor and a second air conveyor near the corner exit end of the cigarette pack conveying channel. The first air conveyor is upstream of the second air conveyor, and the two work together. A cigarette pack appearance inspection component is downstream of the second air conveyor, positioned at a first notch on the side wall of the cigarette pack conveying channel, with its inspection end passing through the first notch and facing into the channel. A defective cigarette pack rejection component is downstream of the appearance inspection component, positioned at a second notch on the side wall of the channel. The appearance inspection component communicates with the defective cigarette pack rejection component via a controller. When cigarette packs packaged by the GDH1000 packaging machine are conveyed to the corner of the channel and become stuck together, the first air conveyor near the corner exit end of the channel blows air onto the side wall of one of the cigarette packs, and the air conveyor in the cigarette pack conveying channel... Near the corner exit of the conveyor belt, a second air conveyor blows air onto the side wall of another cigarette pack. With the combined blowing of the first and second air conveyors, the cigarette packs that are tightly pressed together at the corner are separated from each other. Simultaneously, the separated cigarette packs and their contents quickly pass through the corner of the conveyor belt. The separated cigarette packs, having passed through the corner, continue to be conveyed to the cigarette pack appearance inspection unit. The appearance inspection unit then inspects the appearance of the passing cigarette packs. If a defective cigarette pack is detected, it is removed from the conveyor belt by a defective cigarette pack rejection unit located downstream of the appearance inspection unit. If no defective cigarette pack is detected, it is conveyed to the cigarette packaging station for subsequent boxing. This addresses the problem of high false rejection rates by the imaging detection device due to the tight contact between cigarette packs at the corner of the conveyor belt, leading to high scrap rates in cigarette pack forming, high consumption of auxiliary materials, and increased cigarette production costs.

Detailed Implementation

[0025] like Figure 1-2 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example

[0027] An additional conveyor channel for inspecting the appearance of cigarette packs has been added between the existing GDH1000 cigarette packing machine and the cigarette box station. While this can remove defective cigarette packs from the conveyor channel to some extent, the following drawbacks still exist in actual use:

[0028] Because there are corners in the upper part of the cigarette pack conveyor channel, when the GDH1000 packaging machine packs too fast, the speed of the small cigarette packs slows down at the corners of the conveyor channel. This causes the top and bottom of the cigarette packs to stick together. As a result, when these small cigarette packs are conveyed to the cigarette pack defect detection instrument in the conveyor channel, the instrument cannot detect the area where the top and bottom of the cigarette packs are stuck together, leading to false rejection by the instrument. This not only increases the scrap rate of cigarette pack forming, but also increases the consumption of auxiliary materials and the cost of cigarette production.

[0029] Therefore, this application proposes an energy-saving cigarette pack separation device to solve the problems of high false rejection rate of GDH1000 small pack imaging detection device, which leads to high scrap rate of cigarette pack forming, high consumption of auxiliary materials and increased cigarette production cost.

[0030] For details, please refer to Figure 1 An energy-saving cigarette pack separation device includes a cigarette pack conveying channel 1, a cigarette pack turning pneumatic conveyor 3, a cigarette pack appearance inspection component 6, and a defective cigarette pack rejection component 8. The cigarette pack conveying channel 1 has a corner 2. The cigarette pack turning pneumatic conveyor 3 includes a first pneumatic conveyor 4 and a second pneumatic conveyor 5, which are respectively disposed on the inner sidewall of the corner 2. The first pneumatic conveyor 4 is located upstream of the second pneumatic conveyor 5, and the two pneumatic conveyors 4 and 5 work together. The cigarette pack appearance inspection component 6 is located downstream of the second pneumatic conveyor 5 and is disposed at a first notch 7 on the sidewall of the cigarette pack conveying channel 1. The detection end of the cigarette pack appearance inspection component 6 passes through the first notch 7 and faces into the cigarette pack conveying channel 1. The defective cigarette pack rejection component 8 is located downstream of the cigarette pack appearance inspection component 6 and is disposed at a second notch 9 on the sidewall of the cigarette pack conveying channel 1. The cigarette pack appearance inspection component 6 is communicatively connected to the defective cigarette pack rejection component 8 through a controller.

[0031] In practical application, when cigarette packs packaged by the GDH1000 packaging machine are conveyed to a corner on the conveyor channel and become stuck together, a first air-feeding component 4, located near the exit end of the corner 2 on the cigarette pack conveyor channel 1, blows air onto the side wall of one cigarette pack, and a second air-feeding component 5, also located near the exit end of the corner 2 on the cigarette pack conveyor channel 1, blows air onto the side wall of the other cigarette pack. Thus, with the combined blowing of the first air-feeding component 4 and the second air-feeding component 5, the tightly stuck cigarette packs at the corner are separated, and the separated cigarette packs quickly pass through the corner 2 on the conveyor channel 1, then remain separated and continue to pass through the conveyor channel. The cigarette packs at the corner 2 on channel 1 continue to be conveyed by channel 1 to the cigarette pack appearance inspection unit 6. The cigarette pack appearance inspection unit 6 then inspects the appearance of the passing cigarette packs. If the cigarette pack appearance inspection unit 6 detects a defective cigarette pack, the defective cigarette pack rejection unit 8 located downstream of the cigarette pack appearance inspection unit 6 rejects it from the conveying channel 1. If the cigarette pack appearance inspection unit 6 does not detect a defective cigarette pack, it is conveyed by channel 1 to the cigarette packaging box station for subsequent boxing. This solves the problem that small cigarette packs are tightly stuck together at the corner of the conveying channel, resulting in a high false rejection rate of the imaging detection device, leading to a high scrap rate in cigarette pack forming, high consumption of auxiliary materials, and increased cigarette production costs.

[0032] Please see Figure 2 The first air delivery component 4, which is used to work with the second air delivery component 5 to blow tightly packed cigarette packs to separate them, includes a first air pipe 22, a first regulating air valve 10, and a first air outlet 11.

[0033] It should be noted that the first vent 11 is inclined, that is, the first vent 11 is inclined in the direction downstream of the corner 2.

[0034] It should be noted that the first regulating valve 10 has a regulating function to adjust the degree of accelerated separation of the tobacco pack, thereby meeting the requirements of tobacco pack separation at different operating speeds.

The second regulating air valve 13 is connected to the air delivery end of the second air compressor on the ground through the second air pipe 12.

[0036] It should be noted that the second vent 14 is inclined, that is, the second vent 11 is inclined toward the cigarette pack appearance inspection piece downstream of the conveying channel.

[0037] It should be noted that the second regulating valve 13 has a regulating function to adjust the degree of accelerated separation of the tobacco pack, thereby meeting the requirements of tobacco pack separation at different operating speeds.

[0039] It should be noted that the imaging detector is existing equipment in the cigarette factory, and its structure has not been improved or redesigned, so its structure will not be described in detail.

[0040] Please see Figure 2 The defective cigarette pack rejection component 8, used for rejecting defective cigarette packs detected by the imaging inspection instrument, includes a gas collecting plate 17, a third air hole 18, and a third air pipe 19.
