Description

Technical Field

[0001] This invention relates to the field of cigarette production equipment technology, and in particular to a rejection and collection box and its usage method. Background Technology

[0002] In the production process of finished cigarettes, it is often necessary to remove defective cigarettes or packs that fail inspection. In the existing technology, the removed cigarettes are usually collected by free-falling into a simple container.

[0003] To improve production efficiency, defective cigarettes are removed very quickly, resulting in a high speed at which they fall freely within the collection box. Consequently, the impact force they experience when they come into contact with the simple box is also very strong, making it easy for the cigarettes inside to deform or be directly damaged. This hinders their reuse and increases unnecessary costs, which urgently needs to be improved. Summary of the Invention

[0004] One object of the present invention is to provide a rejection and storage box, which, through the arrangement of a first buffer component and a second buffer component, can fully buffer the cigarettes that fall into it due to rejection, effectively preventing the cigarettes from being deformed or damaged, reducing costs, and avoiding waste.

[0005] To achieve the above objectives, the present invention provides a rejection storage box, comprising:

[0006] The container has an opening at the top;

[0007] A first buffer assembly is located at the opening. The first buffer assembly includes a buffer strip and two mounting members. The buffer strip extends along a first direction and is disposed between the two mounting members for receiving the product. The two mounting members are spaced apart on the housing along the first direction. The mounting members are used to adjust the tension of the buffer strip. There is a gap between the buffer strip and the housing.

[0008] A second buffer assembly is disposed inside the housing, and the second buffer assembly is located below the first buffer assembly.

[0009] As an alternative to the aforementioned removal storage box, at least two of the second buffer components are provided in the box along the height direction.

[0010] As an alternative solution to the aforementioned removal of the storage box, the mounting components include:

[0011] Mounting brackets are provided on the housing;

[0012] A rotating shaft is rotatably mounted on the mounting bracket, and the buffer belt is wound around the rotating shaft;

[0013] A driving component, mounted on the mounting bracket, is used to drive the rotating shaft to rotate in order to adjust the tension of the buffer belt.

[0014] As an alternative to the aforementioned removal storage box, the second buffer component includes:

[0015] A tray is provided on the side of the box body;

[0016] A cushioning pad is horizontally supported on the tray.

[0017] As an alternative to the aforementioned rejection storage box, the rejection storage box also includes a box door, which is located on the side of the box body; the box door is a visible box door.

[0018] As an alternative solution for the aforementioned removal storage box, the buffer strip and the box body have the gap in a second direction, where the first direction is perpendicular to the second direction.

[0019] As an alternative solution for the aforementioned elimination storage box, the two sides of the box body along the second direction are respectively the first side and the second side, and the height of the second side is higher than the height of the first side; the first direction is perpendicular to the second direction.

[0020] As an alternative to eliminating storage boxes mentioned above, the following also includes:

[0021] The first sensing component is used to obtain the height signal of the second buffer component.

[0022] As an alternative to eliminating storage boxes mentioned above, the following also includes:

[0023] The second sensing component is used to obtain the weight signal of the box.

[0024] Another objective of this invention is to provide a method for using the aforementioned rejection and storage box. This method enables the use of the rejection and storage box to provide sufficient cushioning for the cigarettes during the rejection and falling process, effectively preventing deformation or damage to the cigarettes.

[0025] To achieve the above objectives, the present invention also provides a method for using the aforementioned rejection storage box, comprising the following steps:

[0026] 1) Before starting the storage process, first check the height of the second buffer component;

[0027] 2) Adjust the tension of the buffer strip according to the height of the second buffer component, and make the lowest point of the buffer strip and the second buffer component have a gap in the height direction;

[0028] 3) Start the storage process. The product enters the box through the opening, is cushioned by the buffer strip, and then falls onto the second buffer assembly through the gap.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] The rejection and storage box of the present invention, through the setting of a first buffer component and a second buffer component, allows cigarettes to fall onto the buffer strip of the first buffer component during the process of entering the box, where they are first buffered by the buffer strip. Then, the cigarettes fall onto the second buffer component through the gap between the buffer strip and the box, where they are buffered a second time. This achieves double buffering of the rejected cigarettes, preventing the cigarettes from being deformed or damaged, allowing the cigarettes to be recycled and reused, and reducing costs.

[0031] The method of using the rejection and storage box of the present invention involves first detecting the height of the second buffer component before storage, and then adjusting the tension of the buffer belt according to the height of the second buffer component. This ensures that there is a gap between the lowest point of the buffer belt and the second buffer component. After the cigarettes enter the box through the opening, they are buffered by the buffer belt and fall onto the second buffer component through the gap. This height gap between the buffer belt and the second buffer component ensures that the rejection and storage box can fully achieve double buffer storage, improve the buffering effect, prevent the cigarettes from deforming or being damaged, and allow the cigarettes to be recycled and reused, reducing costs and avoiding unnecessary waste.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] like Figures 1 to 5 As shown, this embodiment provides a rejection and storage box, which includes a box body 10, a first buffer assembly 20, and a second buffer assembly 30. The top of the box body 10 has an opening 11. The first buffer assembly 20 is located at the opening 11. The first buffer assembly 20 includes a buffer strip 21 and two mounting members 22. The buffer strip 21 extends along a first direction (i.e., the X direction in the drawing) between the two mounting members 22 to receive the product. The two mounting members 22 are spaced apart on the box body 10 along the first direction. The mounting members 22 are used to adjust the tension of the buffer strip 21. A gap 40 exists between the buffer strip 21 and the box body 10. The second buffer assembly 30 is located inside the box body 10, below the first buffer assembly 20. In this embodiment, the product is a finished cigarette, which can be a cigarette pack or a cigarette carton.

[0050] In practice, finished cigarettes rejected on the production line enter the box 10 through the opening 11 and fall onto the buffer belt 21 of the first buffer component 20, where they are received by the buffer belt 21 to complete the first buffering. Since the rejection speed is too fast, the cigarettes cannot stop after being buffered by the buffer belt 21. They can fall into the box 10 through the gap 40 between the buffer belt 21 and the box 10, where they are received by the second buffer component 30 to complete the second buffering, and finally fall steadily onto the second buffer component 30.

[0051] The rejection collection box of the present invention, through the setting of the first buffer component 20 and the second buffer component 30, allows cigarettes to fall onto the buffer strip 21 of the first buffer component 20 during the process of entering the box body 10, where they undergo the first buffering. Then, the cigarettes fall onto the second buffer component 30 through the gap 40 between the buffer strip 21 and the box body 10, where they undergo the second buffering. This achieves double buffering of the rejected cigarettes, preventing deformation or damage to the cigarettes, allowing them to be recycled and reused, and reducing costs.

[0052] Furthermore, since the tension of the buffer band 21 in the first buffer assembly 20 is adjustable, when the tension of the buffer band 21 is high, that is, when the buffer band 21 is taut between the two mounting members 22, the deformation space of the buffer band 21 is limited. Especially when the entry speed of the cigarette itself is also high, the buffer band 21 can quickly slow down the cigarette, but the impact speed of the cigarette on the buffer band 21 will be high. The cigarette may bounce several times on the buffer band 21 (or it may not bounce) before falling into the second buffer assembly 30 below through the gap. When the tension of the buffer band 21 is low, that is, when the extension length of the buffer band 21 between the two mounting members 22 is long, it will not be taut. At this time, the buffer band 21 is relatively soft and will form a V-shape under its own gravity. That is, the buffer band 21 has a lowest point, as shown in the reference. Figure 4 The V-shaped buffer strip 21 has a certain deformation space after contacting the cigarette, improving the buffering effect and reducing the bouncing of the cigarette (especially cigarettes falling at high speed). Ultimately, it allows the cigarette to smoothly pass through the gap 40 and reach the second buffer component 30 for further buffering. In either case, the buffering setup of the two components reduces damage compared to the cigarette falling directly into the box 10. In practice, the tension of the buffer strip 21 is adjusted appropriately using the mounting component 22 based on the removal speed of the cigarette, the specific placement height of the removal and storage box, and the weight of the cigarette, ultimately achieving smooth buffering and storage of the cigarette. Optionally, the buffer strip 21 is made of canvas; canvas is durable and inexpensive.

[0053] refer to Figure 2 Furthermore, the aforementioned gap 40 exists between the buffer strip 21 and the housing 10 in the second direction (i.e., the Y direction in the attached figure), and the first and second directions are perpendicular to each other. In this embodiment, the first direction is the length direction of the housing 10, that is, the buffer strip 21 extends along the length direction of the housing 10, and the two mounting members 22 are provided on both sides of the housing 10 along the length direction; furthermore, the second direction is the width direction of the housing 10, that is, the aforementioned gap 40 exists between the buffer strip 21 and the housing 10 in the width direction. Of course, in other embodiments, the first direction can be the width direction of the housing 10, and the second direction can be the length direction of the housing 10.

[0054] In specific implementation, refer to Figure 1 , Figure 2 and Figure 4 The product enters the box 10 through the opening 11 in the second direction and comes into contact with the buffer strip 21 for cushioning. Specifically, the two sides of the box 10 in the second direction are a first side 12 and a second side 13. The first side 12 and the buffer strip 21, and the second side 13 and the buffer strip 21, both have the aforementioned gap 40 in the second direction to facilitate the cigarettes falling in. Further, if the product enters the box 10 first through the first side 12, the height of the buffer strip 21 should be lower than the height of the first side 12 to ensure the product can smoothly reach the buffer strip 21 for cushioning and storage. Optionally, the height of the second side 13 is higher than the height of the first side 12, i.e., the higher second side 13 acts as a barrier to prevent products entering the box 10 at excessive speed from directly exiting the box 10, or products bouncing during the cushioning process from being ejected from the second side 13 and unable to be stored. (Reference) Figure 1 and Figure 2 More specifically, baffles 16 are also provided on both sides of the second side 13 along the first direction to further enhance the containment effect and prevent the product from falling out of the box 10. In specific implementation, the first side 12, the second side 13 and the baffles 16 of the box 10 can be integrally formed.

[0055] Furthermore, at least two second buffer components 30 are provided along the height direction within the housing 10. In this embodiment, reference is made to... Figure 2 and Figure 4Two second buffer components 30 are provided along the height direction. In some other embodiments, only one second buffer component 30 may be provided, or three, four, etc. Since a traditional storage box is a hollow box, the cigarettes that fall in will pile up at the bottom of the box 10, and the entire box 10 needs to be moved when it is retrieved. However, in this embodiment, a second buffer component 30 of a suitable height can be selected to cooperate with the first buffer component 20. When the cigarettes it carries reach their limit, only that layer of second buffer component 30 and the cigarettes it carries need to be removed. The remaining layers of second buffer components 30 can continue to be used for storage without moving the entire box 10, which improves the applicability of the entire rejection storage box and also improves storage efficiency. In practical implementation, the second buffer components 30 can be arranged one by one from low to high for buffering and storage operations. That is, the bottommost second buffer component 30 is used for buffering and storage first. After it reaches its load-bearing limit, the next layer of second buffer components 30 is then put into operation. This process is carried out progressively upwards, with layered buffering and storage to increase the overall capacity of the rejection storage box. Furthermore, the number and height of the second buffer components 30 can be adaptively adjusted to make the capacity of the entire rejection storage box adjustable, further improving the applicability of the rejection storage box.

[0056] Specifically, please refer to Figure 2 and Figure 4 The second buffer assembly 30 includes a tray 31 and a buffer pad 32; the tray 31 is located on the side of the box body 10, and the buffer pad 32 is horizontally supported on the tray 31. Optionally, the buffer pad 32 is a sponge pad, which has excellent cushioning effect and is inexpensive and durable. Further, the tray 31 supports the buffer pad 32 at both ends along the second direction. In some other embodiments, the tray 31 may also support the buffer pad 32 at both ends along the first direction. Furthermore, the tray 31 is detachably connected to the box body 10, so that the tray 31 is adjustable in the height direction of the box body 10, further improving the applicability of the rejection storage box.

[0057] In practical use, when using a certain layer of second buffer component 30, it should be ensured that there is no other second buffer component 30 above it, or that the buffer pad 32 of the second buffer component 30 is not present, to avoid interference. When the buffer pad 32 of this layer has borne the cigarettes and reached its limit load-bearing value, the buffer pad 32 and the cigarettes it carried can be removed from the side of the box 10 together, while other layers of second buffer components 30 are arranged for continued storage, so that the removal and storage process remains efficient and continuous.

[0058] refer to Figure 3 and Figure 5The rejection storage box also includes a door 14, which is located on the side of the box body 10. Since the first buffer assembly 20 is located at the top of the box body 10, the side-mounted door 14 is designed to facilitate easy retrieval of rejected products by staff without interfering with the first buffer assembly 20 or the use of the second buffer assembly 30 on other layers. Specifically, the door 14 is a visual door. The use of a visual door 14 means that a transparent observation opening is provided on the side of the box body 10, allowing staff to manually observe the storage progress and prevent excessive accumulation of cigarettes or other emergencies. Optionally, the visual door can be a glass door.

[0059] Furthermore, the storage box also includes a locking component 15, which is used to lock the box door 14 onto the box body 10 to prevent the box door 14 from being pressed open by the accumulated products.

[0060] Specifically, the mounting component 22 includes a mounting bracket, a rotating shaft, and a driving component. The mounting bracket is mounted on the housing 10; the rotating shaft is rotatably mounted on the mounting bracket, and the buffer belt 21 is wound around the rotating shaft; the driving component is mounted on the mounting bracket and is used to drive the rotating shaft to rotate, thereby adjusting the tension of the buffer belt 21. In a specific implementation, the driving component is a motor, and the output shaft of the motor drives and connects to the rotating shaft. By driving the rotating shaft to rotate, the winding length of the buffer belt 21 on the rotating shaft is adjusted, thereby adjusting its tension. In one embodiment, one of the two mounting components 22 may include a driving component, while the other mounting component 22 may not have a driving component. The rotating shaft on the mounting component 22 without a driving component passively rotates to complete the winding. Of course, both mounting components 22 may also be equipped with driving components, and the two driving components may cooperate with each other to achieve different tensions of the buffer belt 21.

[0061] Alternatively, the mounting component 22 may also include an encoder, which is used to detect the rotational speed and rotational angle of the rotating shaft, i.e., to record the tension parameters of the buffer belt 21, providing relevant data for the intelligent control of the final rejection and storage operation.

[0062] This embodiment also provides a method for using the above-mentioned rejection storage box, including the following steps:

[0063] 1) Before starting the storage process, first check the height of the second buffer component 30;

[0064] 2) Adjust the tension of the buffer belt 21 according to the height of the second buffer assembly 30, and make the lowest point of the buffer belt 21 and the second buffer assembly 30 have a gap in the height direction.

[0065] 3) Start the storage process. The product enters the box 10 through the opening 11, is buffered by the buffer belt 21, and then falls onto the second buffer component 30 through the gap 40.

[0066] In practical implementation, if the second buffer component 30 is set too low, creating a large gap between it and the buffer strip 21 of the first buffer component 20, then the height space of the entire box 10 is not fully utilized. If the second buffer component 30 is set too high, contacting the buffer strip 21, then not only will the buffer strip 21 not be effectively tensioned, thus failing to properly cushion and support the products, but there will also not be enough space between the second buffer component 30 and the buffer strip 21 to accommodate the products. It is possible that space will be exhausted after only a few products are stored. Neither of these situations is conducive to the effective use of the rejection storage box. Therefore, in this embodiment, the second buffer component 30 and the buffer strip 21 are required to have a certain gap in the height direction. This gap ensures that the rejection storage box can fully achieve double buffering and storage, improving the buffering effect while also increasing the storage capacity.

[0067] In practical implementation, if the buffer strip 21 is not horizontally taut, it will form a V-shape under its own weight, and the lowest point of the buffer strip 21 will be the lowest point of the V-shaped structure. If the buffer strip 21 is horizontally taut, it will form a straight line with a uniform height, and the lowest point of the entire buffer strip 21 will also be uniform, referring to the height of the buffer strip 21. As mentioned above in the removal and storage box description, the number and height of the second buffer component 30 are uncertain. Therefore, the second buffer component 30 mentioned in the usage method refers to the second buffer component 30 that is currently in the storage working state.

[0068] Furthermore, the rejection storage box also includes a first sensing component for obtaining the height signal of the second buffer component 30. That is, the first sensing component detects the height of the second buffer component 30. After obtaining the height signal, the first sensing component transmits it to the control system of the rejection storage box. The control system adjusts the tension of the buffer band 21 so that the lowest point of the buffer band 21 is spaced apart from the second buffer component 30 in the height direction. Optionally, the first sensing component includes a position sensor.

[0069] In one embodiment, the method of using the above-mentioned elimination storage box further includes the following steps:

[0070] The storage stops when the buffer strip 21 comes into contact with the second buffer assembly 30 or the product carried on the second buffer assembly 30.

[0071] This step includes, but is not limited to, the following situations: First, products continuously accumulate on the second buffer component 30 until they reach the buffer strip 21. At this point, the buffer strip 21 is deformed by the products below and can no longer effectively buffer, making it unsuitable for further storage. Therefore, it is determined that the storage is saturated and storage needs to be stopped. Second, products on the second buffer component 30 do not contact the buffer strip 21, but products accumulate on the buffer strip 21, causing it to deform and fall until it contacts the second buffer component 30 or the products on it. At this point, it is also determined that the storage is saturated and storage needs to be stopped.

[0072] In another embodiment, the storage stops when the product carried on the second buffer strip 21 reaches a preset height.

[0073] This decision to stop product collection is based on the degree of product accumulation on the second buffer strip 21. If the product accumulation height on the second buffer assembly 30 exceeds a preset value, the control system receives a corresponding signal and issues an early warning, promptly reminding staff to handle the situation manually. Optionally, the product height on the second buffer assembly 30 can also be obtained through the first sensing component.

[0074] In another embodiment, the storage stops when the weight of the box 10 exceeds a preset weight.

[0075] In this case, the storage level is not monitored by the height indicator, but by the weight indicator. This is because regardless of whether the product falls on the first buffer component 20 or the second buffer component 30, as long as it falls into the box 10, it will increase the weight of the box 10. Therefore, a limit value that the box 10 can withstand is set, namely the preset weight. Once the total weight of the box 10 exceeds this preset weight, the system will issue a warning and stop storing.

[0076] To achieve the above operations, the storage box also includes a second sensing component, which is used to obtain the weight signal of the box body 10. Optionally, the second sensing component is a weight sensor. Specifically, the second sensing component is located at the bottom of the box body 10.

[0077] The storage box also includes a third sensing component, which includes at least one through-beam photoelectric sensor. Specifically, when only one second buffer component 30 is provided, the third sensing component includes one through-beam photoelectric sensor; when multiple second buffer components 30 are provided in the height direction, each layer of the second buffer component 30 is provided with a corresponding through-beam photoelectric sensor. In specific implementation, when a buffer pad 32 is placed on a certain layer of second buffer component 30, the through-beam photoelectric sensor corresponding to that layer of second buffer component 30 sends a signal to the control system, informing the control system that the buffer pad 32 of that layer of second buffer component 30 is in place, providing a basis for subsequent judgment by the control system.

[0078] In practice, the operation control of the rejection and storage box provided in this embodiment can be incorporated into the remote terminal control system of the entire cigarette production line, thereby realizing the automation of rejection and storage operation, real-time monitoring of multiple rejection and storage boxes in multiple production lines, improving fault early warning function, parameter (such as preset weight) adjustment function, and maintenance demand prediction based on historical data. The ultimate goal is to facilitate management and scheduling and improve the overall production efficiency of the workshop.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
