Description

Technical Field

[0001] This invention relates to the field of tobacco packaging equipment and process technology, and in particular to a packaging equipment and process flow for vertical cigarette packs. Background Technology

[0002] With the continued expansion of demand for new tobacco products, the need for vertically arranged cigarette packs in various irregular packaging formats has also emerged. Current technology primarily involves first stacking horizontally packed cigarette packs into groups, then using packaging wheels to stand the groups upright before outputting them. The disadvantage of this technology is that it has specific requirements regarding the front and back orientation of the cigarette packs. If customers wish to change the orientation, an additional flipping mechanism must be added, increasing the cost of the tobacco packaging machine. Furthermore, due to the unique nature of the flipping mechanism, the additional mechanism can only be used on specific packaging lines, resulting in low compatibility. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a packaging equipment and packaging process for vertical cigarette packs, in order to solve the problems of low compatibility and high cost caused by the need to add an extra flipping mechanism for changing the direction of cigarette packs in the prior art.

[0004] To achieve the above and other related objectives, the present invention provides a packaging device for vertical cigarette packs, comprising an upstream conveyor belt, a midstream conveyor belt, a midstream spiral roller, a plate chain, a downstream conveyor belt, a downstream stacking belt, and a pusher. The upstream conveyor belt transports unphased cigarette packs from the previous process. The midstream conveyor belt receives the unphased cigarette packs from the upstream conveyor belt and transforms them into continuous phased cigarette packs for output. The midstream spiral roller receives the phased cigarette packs output from the midstream conveyor belt and transforms them into discrete phased cigarette packs. The plate chain receives the discrete phased cigarette packs output from the midstream spiral roller and transforms the horizontal cigarette packs into vertical cigarette packs via the plate chain. The downstream conveyor belt receives the vertical cigarette packs output from the plate chain and maintains the vertical movement of the cigarette packs. The downstream stacking belt stacks the vertical cigarette packs into groups and creates a distance between adjacent groups. The pusher pushes the stacked cigarette packs from the downstream stacking belt into subsequent processes.

[0005] Preferably, the midstream conveyor belt is detachably equipped with a flipping guide rail, and the cigarette packs on the midstream conveyor belt are flipped face-up or face-down under the action of the flipping guide rail.

[0006] Preferably, there are two midstream spiral rollers, and the ends of the midstream spiral rollers are connected to a spiral roller drive source; the two midstream spiral rollers rotate in opposite directions at a constant speed, and the cigarette packs output from the midstream conveyor belt are separated from the cigarette packs in front and behind by the two midstream spiral rollers, becoming discrete cigarette packs with phase.

[0007] Preferably, there are two plate chains, and several plate chain baffles are provided on the outer ring wall of the plate chains. The two plate chains are arranged in parallel, and the plate chain baffles between two adjacent outer ring walls cooperate to transport the cigarette packs output by the midstream spiral roller.

[0008] Preferably, the downstream conveyor belt is used to receive the vertical tobacco packs output by the plate chain, and there are two downstream conveyor belts, which are respectively arranged on the upper side and the lower side of the vertical tobacco packs; the transmission speed of the downstream conveyor belt is the same as the transmission speed of the plate chain.

[0009] Preferably, there are at least two downstream stacking belts, which are respectively arranged on the upper and lower sides of the vertical cigarette packs; stacking belt blocks are arranged at equal intervals on the downstream stacking belts, and the stacking belt blocks block the vertical cigarette packs transported by the downstream conveyor belt to stack them into groups and to separate the cigarette packs between two adjacent groups.

[0010] Preferably, there are two pushers, which work together alternately to push the stacked cigarette packs from the downstream stacking belt into the subsequent process.

[0011] To achieve the above or other objectives, the present invention also discloses a packaging process for vertical cigarette packs, employing the aforementioned packaging equipment for vertical cigarette packs, wherein a detachable tilting guide rail is detachably installed on the upstream conveyor belt; the upstream conveyor belt is the first section, the section of the midstream conveyor belt with the tilting guide rail is the second section, the section of the midstream conveyor belt without the tilting guide rail is the third section, the midstream spiral roller is the fourth section, the plate chain is the fifth section, the downstream conveyor belt and the downstream stacking belt are the sixth section, and the pusher is the seventh section; the steps are as follows:

[0012] S1: The upstream conveyor belt in the first section will transport the phaseless cigarette packs transported in the previous process;

[0013] S2: The flipping guide rail in the second section flips the phaseless cigarette packs output from the first section to either the front or the back.

[0014] S3: The midstream conveyor belt in the third section receives the phaseless smoke packs output from the first section and transforms the phaseless smoke packs into continuous phased smoke packs;

[0015] S4: The midstream spiral roller in the fourth section receives the continuous phase smoke pack output from the third section and turns the continuous phase smoke pack into a discrete phase smoke pack;

[0016] S5: The plate link in the fifth section receives the discrete phase smoke packs output from the fourth section and turns the horizontal smoke packs into vertical smoke packs;

[0017] S6: The downstream conveyor belt in the sixth section receives the vertical smoke packs output by the plate chain and maintains the movement of the vertical smoke packs;

[0018] S7: The downstream stacking belt in the sixth section stacks the vertical cigarette packs transported by the downstream conveyor belt into groups and increases the distance between the cigarette packs of two adjacent groups.

[0019] S8: The pushers in the seventh section push the vertically stacked cigarette packs in the downstream stacking belt into the subsequent process.

[0020] Preferably, if the produced cigarette packs do not require front-side or back-side flipping, the flipping guide rail can be removed from the midstream conveyor belt, and step S3 can be directly performed after step S1 is completed.

[0021] As described above, the packaging equipment and packaging process for vertical cigarette packs of the present invention have the following beneficial effects:

[0022] The present invention relates to packaging equipment and packaging process for vertical cigarette packs, which uses a midstream spiral roller instead of the packaging wheel in the prior art to complete the horizontal turning of the cigarette pack; uses a plate chain instead of the packaging wheel in the prior art to complete the vertical standing of the cigarette pack; and uses a downstream stacking belt with stacking blocks to complete the stacking of vertical cigarette packs. Moreover, according to customer needs, only a few parts need to be replaced to obtain different cigarette packs with the front or back facing up, improving product compatibility and reducing product cost.

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0032] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0033] This invention relates to a packaging device for vertical cigarette packs. For ease of description, the length direction of the midstream conveyor belt 3 is defined as the left-right direction, the height direction as the up-down direction, and the width direction as the front-back direction. Figure 1 Establish a spatial rectangular coordinate system, where the positive direction of the X-axis is the right direction, the positive direction of the Y-axis is the forward direction, and the positive direction of the Z-axis is the upward direction.

[0034] like Figure 1 As shown, the present invention provides a packaging device for vertical cigarette packs, including an upstream conveyor belt 1, a midstream conveyor belt 3, a midstream spiral roller 4, a plate chain 5, a downstream conveyor belt 6, a downstream stacking belt 7, and a pusher. The upstream conveyor belt 1 transports the unphased cigarette packs transported in the previous process. The midstream conveyor belt 3 receives the unphased cigarette packs transported by the upstream conveyor belt 1 and transforms them into continuous phased cigarette packs for output. The midstream spiral roller 4 receives the phased cigarette packs output by the midstream conveyor belt 3 and transforms them into discrete phased cigarette packs. The plate chain 5 receives the discrete phased cigarette packs output by the midstream spiral roller 4 and transforms the horizontal cigarette packs into vertical cigarette packs through the plate chain 5. The downstream conveyor belt 6 receives the vertical cigarette packs output by the plate chain 5 and maintains the movement state of the vertical cigarette packs. The downstream stacking belt 7 stacks the vertical cigarette packs into groups and separates the cigarette packs between adjacent groups. The pusher pushes the cigarette packs stacked in groups by the downstream stacking belt 7 into subsequent processes.

[0035] The present invention relates to a packaging equipment for vertical cigarette packs, which completes the horizontal turning of the cigarette packs through the midstream spiral roller 4, changes the cigarette packs from a horizontal state to a vertical state through the plate chain 5, and completes the stacking of vertical cigarette packs through the downstream stacking belt 7 equipped with stacking belt stops 701. Then, the stacked vertical cigarette packs are pushed to the subsequent processes by the pusher, which improves product compatibility and reduces product cost.

[0036] Furthermore, in this embodiment, the presence of phase in the cigarette pack indicates that the position of the cigarette pack and the phase of the main motor can correspond to each other, while the absence of phase in the cigarette pack indicates that the position of the cigarette pack and the phase of the main motor cannot correspond to each other.

[0037] For example, "no phase on the smoke packs on upstream conveyor belt 1" means that the phase of the smoke packs corresponds to the phase of the motor on upstream conveyor belt 1. When there is congestion downstream, upstream conveyor belt 1 is still operating, but the smoke packs may stop on upstream conveyor belt 1.

[0038] The term "continuous cigarette pack phase" on the midstream conveyor belt 3 means that the phase of the cigarette pack corresponds to the phase of the motor on the midstream conveyor belt 3. That is, when downstream congestion occurs, the midstream conveyor belt 3 will stop, and the cigarette pack will also stop. In this embodiment, the continuous cigarette pack phase on the midstream conveyor belt 3 can be achieved by setting two midstream conveyor belts 3, one above and one below the cigarette pack, respectively, so that the two midstream conveyor belts 3 clamp the cigarette pack.

[0039] The discrete phase of the tobacco pack on the midstream spiral roller 4 means that the phase of the tobacco pack corresponds to the phase of the motor of the midstream spiral roller 4. That is, when congestion occurs downstream, the midstream spiral roller 4 will stop, and the tobacco pack will also stop.

[0040] Correspondingly, the cigarette packs on plate chain 5, downstream conveyor belt 6, and downstream stacking belt 7 all have the same phase meaning as described above, and will not be repeated here.

[0041] Preferred, such as Figure 1 As shown, a flipping guide rail 2 is detachably installed on the midstream conveyor belt 3. The cigarette packs on the midstream conveyor belt 3 are flipped face-up or face-down under the action of the flipping guide rail 2. In this embodiment, the flipping guide rail 2 extends horizontally along its length, its height increases from right to left, and its width increases from back to front. Thus, when a cigarette pack moves onto the flipping guide rail 2, the cigarette pack gradually stands upright and turns face-down, thereby achieving the flipping of the cigarette pack face-up or face-down. In other embodiments, the structure of the flipping guide rail 2 can also be of other forms, as long as it can achieve the flipping of the cigarette pack face-up or face-down.

[0042] Preferred, such as Figure 1As shown, there are two midstream spiral rollers 4, and the ends of the midstream spiral rollers 4 are connected to a spiral roller drive source. The two midstream spiral rollers 4 rotate in opposite directions at a constant speed. The cigarette packs output from the midstream conveyor belt 3 are separated from the preceding and following cigarette packs by the two midstream spiral rollers 4, becoming discrete and phased cigarette packs. In this embodiment, the transmission direction of the midstream spiral rollers 4 on the cigarette packs is from right to left. The surface parameters of the midstream spiral rollers 4 depend on the different specifications of the cigarette packs or whether it is necessary to change the orientation of the cigarette packs. As the two midstream spiral rollers 4 rotate in opposite directions at a constant speed, the horizontal cigarette packs are pushed by the curved surfaces of the two midstream spiral rollers 4, which separates the distance between adjacent cigarette packs, making them discrete and phased cigarette packs. The orientation of the cigarette packs in the horizontal direction can be changed according to customer needs.

[0043] Preferred, such as Figure 1 , Figure 2 As shown, there are two plate chains 5. Several plate chain baffles 503 are provided on the outer ring wall of each plate chain 5. The two plate chains 5 are arranged in parallel, and the plate chain baffles 503 between adjacent outer ring walls cooperate to transport the cigarette packs output from the upstream spiral roller 4. In this embodiment, the two plate chains 5 are arranged in parallel along the front-to-back direction. For ease of description, as shown... Figure 2 As shown, the two plate chains 5 are now defined as the first plate chain 501 and the second plate chain 502, with the first plate chain 501 positioned in front of the second plate chain 502. The cross-sectional view of the first plate chain 501 and the second plate chain 502 is an arc shape, and the included angle between the input end and the output end of the first plate chain 501 and the second plate chain 502 is 90 degrees. This enables the horizontal tobacco pack to enter from the input end and then be transformed into a vertical tobacco pack through the transport of the plate chains 5. Figure 2 Only part of the chain baffle 503 is drawn on the chain 5.

[0044] Furthermore, a plurality of chain baffles 503 are spaced apart on the outer ring wall of the chain 5. Therefore, the chain baffles 503 between the rear half of the outer wall of the first chain 501 and the front half of the outer wall of the second chain 502 cooperate to transport the horizontal cigarette packs output from the midstream spiral roller 4. In this embodiment, arc-shaped baffles are also provided on the upper and lower sides of the chain 5. These two arc-shaped baffles block the cigarette packs as they are transported along the chain 5, preventing them from falling off the chain baffles 503. Furthermore, a drive source is provided at the output end of the chain 5, and a tensioning wheel is provided at the input end of the chain 5, thus achieving a closed-loop circulation of the chain 5. In this embodiment, the chain 5 has one more degree of freedom than a regular chain. Therefore, the horizontal cigarette packs output from the midstream spiral roller 4 are transformed into vertical cigarette packs under the clamping and pushing action of the chain 5, and there is a fixed spacing between the vertical cigarette packs. Simultaneously, these vertical cigarette packs have a phase.

[0045] Preferred, such as Figure 1As shown, the downstream conveyor belt 6 is used to receive the vertical cigarette packs output from the plate chain 5. There are two downstream conveyor belts 6, one above and one below the vertical cigarette pack. The transmission speed of the downstream conveyor belt 6 is the same as that of the plate chain 5. In this embodiment, the two downstream conveyor belts 6 transport the cigarette packs. The input ends of the two downstream conveyor belts 6 are connected to the output ends of the plate chain 5. When the vertical cigarette packs flow out from the output ends of the plate chain 5, they are held by the two downstream conveyor belts 6 and transported along with them. The downstream conveyor belts 6 cooperate with the plate chain 5 to ensure that the speed and phase of the vertical cigarette packs remain unchanged after they are connected.

[0046] Preferred, such as Figure 1 , Figures 3-6 As shown, there are at least two downstream stacking belts 7, respectively positioned above and below the vertical cigarette packs. Stacking belt blocks 701 are evenly spaced on the downstream stacking belts 7. These blocks obstruct and stack the vertical cigarette packs transported by the downstream conveyor belt 6, creating a distance between adjacent groups of cigarette packs. Further, in this embodiment, there are four downstream stacking belts 7, with two on the upper and two on the lower sides of the vertical cigarette packs. The downstream conveyor belt 6 on the upper side is positioned between the two downstream stacking belts 7 on the upper side, and the downstream conveyor belt 6 on the lower side is positioned between the two downstream stacking belts 7 on the lower side. The stacking belt blocks 701 are evenly spaced on the downstream stacking belts 7. These blocks decelerate the vertical cigarette packs transported by the downstream conveyor belt 6 and stack a certain number of vertical cigarette packs into groups. The stacked groups of vertical cigarette packs are separated from the adjacent groups of cigarette packs, facilitating the pusher to push the groups of cigarette packs into subsequent processes. Furthermore, in this embodiment, there are four downstream stacking belts 7, which are arranged in pairs on both sides of the two downstream conveyor belts 6. The purpose is to prevent the vertical cigarette pack from shifting in the left or right direction when the stacking belt baffle 701 blocks the vertical cigarette pack.

[0047] Preferred, such as Figure 4 , Figure 6 As shown, there are two pushers. The two pushers work alternately to push the stacked cigarette packs (groups 7) downstream to the next process, where the cigarette packs are packaged into cartons. In this embodiment, the two pushers are pusher A and pusher B, and the running trajectories of pushers A and B are both rectangular. Figures 3-6 As shown, the already stacked tobacco group A is pushed into the subsequent process by pusher A along a rectangular track. Tobacco group B is clamped and conveyed to the left by the downstream conveyor belt 6. Tobacco group B is blocked by the stacking belt block 701 on the downstream stacking belt 7 and gradually stacked into a group. After tobacco group B is formed, pusher B is inserted into the gap between tobacco group B and tobacco group C, repeating the action of pusher A.

[0048] To achieve the above or other objectives, the present invention also discloses a packaging process for vertical cigarette packs, employing the aforementioned packaging equipment for vertical cigarette packs. A tilting guide rail 2 is detachably installed on the upstream conveyor belt 3; the upstream conveyor belt 1 is the first section; the area of ​​the midstream conveyor belt 3 with the tilting guide rail 2 is the second section; the area of ​​the midstream conveyor belt 3 without the tilting guide rail 2 is the third section; the midstream spiral roller 4 is the fourth section; the plate chain 5 is the fifth section; the downstream conveyor belt 6 and the downstream stacking belt 7 are the sixth section; and the pusher is the seventh section. The steps are as follows:

[0049] S1: The upstream conveyor belt 1 in the first section will transport the phaseless cigarette packs transported in the previous process;

[0050] S2: The flipping guide rail 2 in the second section flips the phaseless cigarette packs output from the first section to either the front or the back.

[0051] S3: The midstream conveyor belt 3 in the third section receives the phaseless smoke packs output from the first section and turns the phaseless smoke packs into continuous smoke packs with phase.

[0052] S4: The midstream spiral roller 4 in the fourth section receives the continuous phase smoke pack output from the third section and turns the continuous phase smoke pack into a discrete phase smoke pack.

[0053] S5: The plate chain 5 in the fifth section receives the discrete phase smoke packs output from the fourth section and turns the horizontal smoke packs into vertical smoke packs;

[0054] S6: The downstream conveyor belt 6 in the sixth section receives the vertical smoke packs output by the plate chain 5 and maintains the movement of the vertical smoke packs;

[0055] S7: The downstream stacking belt 7 in the sixth section stacks the vertical cigarette packs transported by the downstream conveyor belt 6 into groups and increases the distance between the cigarette packs of two adjacent groups.

[0056] S8: The pusher in the seventh section pushes the vertically stacked cigarette packs in the downstream stacking belt 7 into the subsequent process.

[0057] Preferably, if the produced cigarette packs do not require front-side or back-side flipping, the flipping guide rail 2 can be removed from the midstream conveyor belt 3, and step S3 can be performed directly after step S1 is completed.

[0058] This invention relates to packaging equipment and a packaging process for vertical cigarette packs. The function of this invention is to transform the continuous horizontal cigarette packs input from the upstream machine into a fixed number of vertically stacked cigarette packs with a clear gap between the groups, and then output them to the downstream machine. A midstream spiral roller 4 replaces the packaging wheels in the prior art to achieve horizontal turning of the cigarette packs; a plate chain 5 replaces the packaging wheels in the prior art to achieve vertical standing of the cigarette packs; and a downstream stacking belt 7 with stacking blocks 701 completes the stacking of the vertical cigarette packs. Furthermore, according to customer needs, only a few parts need to be replaced to obtain different cigarette packs with their front or back facing up, improving product compatibility and solving the problems of low compatibility and high cost caused by the need for an additional flipping mechanism for cigarette pack reversal in the prior art.

[0059] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
