Description

Technical Field

[0001] The utility model relates to the technical field of cigarette inspection tools, in particular to a cigarette product classification and placement device for cigarette inspection. Background Art

[0002] Cigarette inspection is the process of testing the physical, chemical and sensory indicators of cigarettes to ensure that the quality of cigarette products meets national standards and industry requirements, so that consumers can obtain safe and qualified tobacco products, prevent counterfeit and inferior cigarettes from entering the market, maintain normal market order and brand reputation, and confirm the authenticity and quantity of cigarettes through inspection to prevent tax evasion and tax avoidance and protect national fiscal revenue. Therefore, cigarette inspection is a comprehensive process. After the inspection is completed, the samples need to be packaged in packaging bags to prevent the samples from being contaminated by the external environment during storage and transportation to avoid affecting the true state of the samples. It can also prevent the samples from being replaced or tampered with after the inspection. At the same time, it is convenient to trace the source of the samples, the inspection history and related data, which will help the subsequent re-inspection.

[0003] Cigarette inspection is usually completed by specially trained inspectors, and cigarette samples are sent to inspectors through special inspection channels. Due to the large number of cigarette brands and products on the market and frequent market supervision activities, the number of cigarette samples that inspectors need to inspect on a daily basis is often large, and also includes multiple types of cigarette samples of the same type. At the same time, before cigarette identification, it is necessary to arrange the identification order of samples according to certain principles and procedures, and then inspect the samples one by one in the determined order. When there are many cigarette samples and the categories are complicated, the inspection order of each cigarette sample is very easy to be confused, and inspectors are often confused. It is impossible to conduct inspection in the first time, and the order of cigarette samples is easy to be forgotten, which aggravates the possibility of confusion in order. At present, there are tools for uniformly collecting cigarettes on the market, as shown in the Chinese patent with announcement number CN206748375U and patent name "Cigarette Sampling and Inspection Tool Box". The tool box includes an outer box body, a removable inner liner with an open opening arranged in the outer box body, and at least one partition arranged in the cavity of the inner liner and detachably connected to the inner wall of the inner liner by Velcro. The partition divides the cavity of the inner liner into at least two sections, and each partition has at least two working positions in the inner liner.

[0004] The above-mentioned classification and collection tool changes the size of each area inside the inner liner by adjusting the position of the partition, so as to adapt to various quantities and sizes of cigarette samples. However, the toolbox cannot assign corresponding marks according to the specified order of each cigarette sample. Therefore, after the inspection is completed, the cigarette samples can only be arranged by relying on the inspector's memory, resulting in the problem that the cigarette samples are still easy to be confused. Moreover, when the cigarette inspection is completed and needs to be packaged, each cigarette sample needs to be taken out from the inner liner of the outer box one by one, and then placed in a specific packaging bag in order. In this process, the order is easily disordered, and the operation is extremely inconvenient, which affects the efficiency of cigarette inspection. In addition, the unpacked cigarette samples will be exposed to the external environment for too long, affecting the true quality of the cigarette samples. Therefore, the above toolbox cannot meet the needs of cigarette inspection and subsequent packaging. Utility Model Content

[0005] In view of the above situation, in order to overcome the problem that the above-mentioned existing cigarette sampling and inspection tool box cannot assign corresponding marks according to the specified order of each cigarette sample, which leads to easy confusion when the cigarette samples are put back after the inspection and during subsequent packaging, and the packaging operation is inconvenient, affecting the inspection efficiency of the cigarette, and at the same time causing the unpacked cigarette samples to be exposed to the external environment for too long, affecting the true quality of the cigarette samples, the purpose of the utility model is to provide a cigarette product classification and placement device for inspection that can always ensure that the stored and retrieved cigarettes are placed in order during inspection, so that they are not easily confused, and are easy to package, thereby improving the inspection efficiency, and at the same time can avoid the true quality of the unpacked cigarette samples being affected.

[0032] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0034] like Figures 1 to 5 As shown, the utility model relates to a tobacco product classification and placement device for cigarette inspection, which comprises a placement box 1, an isolation rack 2, a cigarette unloading platform 3, a marking plate 4 and a packaging bag 5, wherein the isolation rack 2, the cigarette unloading platform 3 and the marking plate 4 are all arranged in the placement box 1;

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the isolation rack 2 and the cigarette unloading platform 3 are arranged in parallel front and back, wherein the isolation rack 2 and the display box 1 are detachably connected. More specifically, the isolation rack 2 is placed in the display box 1, so that it can be quickly taken out or put back from the display box 1. A cigarette product placement cavity 1a is formed between the isolation rack 2 and the display box 1. The cigarette product placement cavity 1a is used to place cigarette samples. There are several cigarette product placement cavities 1a, thereby increasing the number of cigarette samples that can be placed. Each cigarette product placement cavity 1a is an independent space. After the cigarette samples are placed, each cigarette sample can be fixedly arranged in a certain order to avoid confusion between the placed cigarette samples. After the cigarette samples are inspected, the isolation rack 2 is controlled to move from bottom to top to be removed from the display box 1. The cigarette product placement cavities 1a are connected. At this time, the cigarette samples can still be kept at the position corresponding to the original cigarette product placement cavity 1a to maintain orderly discharge;

[0036] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a cigarette unloading port 1b is formed at the front side of the display box 1, and the cigarette unloading port 1b is open. After the cigarette inspection is completed, the cigarette sample moves to the outside of the display box 1 through the cigarette unloading port 1b. The cigarette unloading platform 3 is slidably connected to the display box 1. By removing the isolation frame 2 and pushing the cigarette unloading platform 3 to the front side of the display box 1, the cigarette unloading platform 3 drives each cigarette sample to move to the outside in an orderly manner.

[0037] like Figure 4 and Figure 5As shown, the marking plate 4 is located at the bottom of the isolation frame 2 and embedded in the bottom of the display box 1. The marking plate 4 has a tobacco product information column 401 corresponding to each tobacco product placement cavity 1a. Each tobacco product information column 401 is independent. The tobacco product information column 401 records the name, serial number and other information of the cigarette sample in the corresponding tobacco product placement cavity 1a. Based on the tobacco product information column 401 being located at the bottom of the corresponding tobacco product placement cavity 1a, the tobacco product information column 401 can be observed from an external perspective. The information in the tobacco product information column 401 provides intuitive feedback to the inspector, thereby quickly determining the placement position corresponding to each cigarette sample, ensuring that the cigarette samples are placed in the tobacco product placement cavity 1a with the corresponding serial number, so as to be arranged in order. Before or after the inspection, the above operation can be performed to effectively avoid confusion between cigarette samples, reduce the error rate in the inspection work, and improve the efficiency of cigarette inspection and subsequent packaging;

[0038] like Figure 1 As shown, the packaging bag 5 is sleeved on the outside of the display box 1, and the isolation rack 2, cigarette unloading platform 3 and marking plate 4 in the corresponding display box 1 are also located in the packaging bag 5, that is to say, the display box 1 can be taken out of the packaging bag 5 to the outside, or put back into the packaging bag 5. Specifically, when inspecting cigarettes, the display box 1 is taken out, and the cigarette product placement cavity 1a formed between the isolation rack 2 is used to hold the cigarette samples to be inspected. After the inspection is completed, the isolation rack 2 is removed, and the display box 1 is inserted into the packaging bag 5 with the cigarette unloading port 1b facing the opening of the packaging bag 5. Then, the cigarette unloading platform 3 is pushed to move, so that each cigarette sample can be simultaneously pushed into the packaging bag 5 in an arrangement consistent with the inspection order and sealed for storage, which simplifies the cumbersome operation of putting the cigarette samples into the packaging bag 5 one by one for storage, avoids the cigarette samples from being exposed to the external environment for too long, affecting the real quality, and correspondingly promotes the further improvement of the cigarette inspection efficiency, so as to be better suitable for daily cigarette inspection work with a large number of cigarette samples.

[0039] like Figures 3 to 7 As shown, the isolation rack 2 includes a plurality of transverse partitions 201 and longitudinal partitions 202 that are staggered horizontally and vertically, so that each transverse partition 201 and longitudinal partition 202 encloses a plurality of rectangular slots, namely, tobacco product placement slots 2a. When the isolation rack 2 is placed in the display box 1, the tobacco product placement slots 2a and the bottom of the display box 1 below form a tobacco product placement cavity 1a.

[0040] like Figure 7As shown, the lower edge of the transverse partition 201 is provided with a plurality of lower card slots 201a, and the upper edge of the longitudinal partition 202 is provided with a plurality of upper card slots 202a, each lower card slot 201a is arranged along the length direction of the transverse partition 201, and each upper card slot 202a is arranged along the length direction of the longitudinal partition 202. The transverse partition 201 is engaged with the upper card slot 202a on the longitudinal partition 202 through the lower card slot 201a, thereby being fixed to the transverse partition 201 to form a detachable connection. That is to say, the transverse partition 201 is located above the longitudinal partition 202, and the transverse partition 201 utilizes its lower card slot 201 a is snapped into the upper slots 202a of the same sequence with each longitudinal partition 202 to form a rectangular tobacco product placement slot 2a. The width of the tobacco product placement slot 2a can be changed by adjusting the interval between adjacent transverse partitions 201. Similarly, the longitudinal partitions 202 can also be adjusted to change the length of the tobacco product placement slot 2a, or a certain number of transverse partitions 201 and longitudinal partitions 202 can be removed to adjust the length and width of the tobacco product placement slot 2a, to ensure that when the isolation rack 2 is placed in the display box 1 to form a tobacco product placement cavity 1a with its bottom, the tobacco product placement cavity 1a can better meet the placement needs of cigarette samples of different packaging sizes.

[0041] like Figures 3 to 8 As shown, the isolation frame 2 also includes a positioning card 203, which is provided with a cross slot 203a. The cross-matching position of the transverse partition 201 and the longitudinal partition 202 is in the shape of a cross. The positioning card 203 is connected to the cross-matching position of the longitudinal partition 202 and the transverse partition 201 through the cross slot 203a, so that the transverse partition 201 and the longitudinal partition 202 maintain a staggered arrangement in the horizontal and vertical directions, and accordingly maintain the rectangular shape of the tobacco placement groove 2a, reducing the possibility of deformation under the action of external force.

[0042] like Figures 8 to 11 As shown, slide grooves 1c are opened on the left and right inner walls of the display box 1, and pulleys 6 are provided on the left and right sides of the smoke unloading platform 3. The pulleys 6 are rollingly connected to the slide grooves 1c on the corresponding sides. The slide grooves 1c provide guidance for the movement of the smoke unloading platform 3 to ensure that its moving path is relative to the smoke unloading port 1b. At the same time, when the smoke unloading platform 3 moves, the pulleys 6 roll in the corresponding slide grooves 1c, thereby reducing the resistance of the smoke unloading platform 3 when it moves, so that it can be moved easily.

[0043] like Fig.10 and Fig.11As shown, the left and right inner walls of the display box 1 are provided with limiting grooves 1d, the limiting grooves 1d are connected with the cigarette unloading port 1b, the marking plate 4 is embedded in the bottom of the display box 1 through the limiting grooves 1d, and the side edges of the marking plate 4 are limited by the upper and lower walls of the limiting grooves 1d to prevent its upward and downward movement, so as to be firmly maintained in the display box 1, the marking plate 4 can slide along the limiting grooves 1d toward the cigarette unloading port 1b to be removed from the display box 1, and when the cigarette samples are loaded into the packaging bag 5, the marking plate 4 is simultaneously put into the packaging bag 5, which can serve as a skeleton to support the packaging bag 5 to prevent it from collapsing, thereby ensuring the neat arrangement of the cigarette samples, and also enabling the re-inspection personnel to intuitively understand the placement order of each cigarette sample during the subsequent re-inspection, thereby providing convenience for the re-inspection work.

[0044] like Figure 1 and Figure 2 As shown, since the cigarette samples are in an unsealed state after inspection, an exhaust valve 7 is provided on the packaging bag 5. The exhaust valve 7 is used to connect to an air pump to extract the air in the packaging bag 5, so that the unsealed cigarette samples can be preserved in a vacuum, preventing impurities in the air from affecting the true quality of the cigarette samples.

[0045] Furthermore, the height of the packaging bag 5 is slightly greater than the height of the display box 1 , thereby providing sufficient storage space for the display box 1 and reducing the difficulty of taking out or putting back the display box 1 from the packaging bag 5 .

[0046] like Fig.10 As shown, the display box 1 includes a bottom plate 101, a left side plate 102, a right side plate 103 and a rear baffle 104. The left side plate 102 is arranged on the left and right sides of the bottom plate 101. The front parts of the left side plate 102 and the right side plate 103 form a smoke unloading port 1b. The rear baffle 104 is arranged on the rear side of the bottom plate 101 and closes the rear parts of the left side plate 102 and the right side plate 103. The bottom plate 101, the left side plate 102, the right side plate 103 and the rear baffle 104 are fixed by threaded fasteners 8. The self-locking property of the threaded connection can realize the stable connection of the bottom plate 101, the left side plate 102, the right side plate 103 and the rear baffle 104, and is easy to assemble the display box 1.

[0047] Combination Figures 1 to 11The specific application scenario of the tobacco product classification and placement device for tobacco inspection of the utility model is as follows. Before the tobacco inspection work is carried out, the inspector puts the corresponding cigarette sample to be inspected into the tobacco product placement cavity 1a formed between the display box 1 and the isolation rack 2 according to the tobacco product name and sequence information in the tobacco product information column 401 on the marking plate 4. The tobacco product placement cavity 1a receives the cigarette samples, so that a large number of cigarette samples can be arranged in order. When the tobacco inspection is completed, the above operation is performed, that is, the unpacked cigarette samples are put back into the corresponding cigarette product placement cavity 1a, which can effectively avoid confusion between cigarette samples, thereby reducing the error rate in the tobacco inspection work and improving the efficiency of tobacco inspection and subsequent packaging. The cigarette packing can also be improved accordingly. After the inspection of the cigarettes is completed, when packaging is required, the isolation rack 2 is first removed from the display box 1. This removal action is an upward movement away from the display box 1, so as to avoid disrupting the arrangement order of the cigarette samples. The display box 1 is then placed in the packaging bag 5. Thereafter, the cigarette unloading platform 3 is pushed toward the cigarette unloading port 1b to slide along the slide groove 1c. The cigarette samples are pushed from the cigarette unloading port 1b to the inside of the packaging bag 5 in the order of arrangement through the cigarette unloading platform 3. Finally, the display box 1 is taken out, the packaging bag 5 is sealed, and the exhaust valve 7 on the packaging bag 5 is connected to the air pump to exhaust the air in the packaging bag 5, so that the unpacked cigarette samples can be sealed and preserved, thereby ensuring the authenticity of the quality of the cigarette samples.

[0048] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
