Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette production, and particularly relates to a packaging machine. Background Art
[0002] In cigarette production, cigarette sticks need to be packaged into carton cigarettes, and then a certain number of carton cigarettes need to be packaged into strip cigarettes. Generally, the process of packaging carton cigarettes into strip cigarettes is completed by a packaging machine. The packaging machine is provided with a feeding structure, a conveying channel, a pusher plate and a strip cigarette packaging mechanism. Among them, the feeding mechanism is provided with a feeding station, and the feeding mechanism is used to transport carton cigarettes to the feeding station. The inlet of the conveying channel is close to the feeding station, and the outlet of the conveying channel is close to the strip cigarette packaging mechanism. A temporary storage station is arranged in the middle of the conveying channel. On the conveying channel, the part between the temporary storage station and the outlet of the conveying channel is a temporary storage section. The pusher plate is installed on a power conveying arm, and the power conveying arm is driven by a cam-link mechanism inside the machine to drive the pusher plate to reciprocate between the feeding station and the temporary storage station, so as to push the carton cigarettes to move in the conveying channel. Generally, the feeding mechanism transports two packs of carton cigarettes (recorded as a group) each time, and the pusher plate pushes two packs of carton cigarettes to move from the feeding station to the temporary storage station each time. After the first group of carton cigarettes moves to the temporary storage station, the pusher plate pushes the second group of carton cigarettes to move to the temporary storage station, and the second group of carton cigarettes will contact the first group of carton cigarettes and push the first group of carton cigarettes to move towards the outlet direction of the conveying channel to the temporary storage section, and so on, until the temporary storage section is full of carton cigarettes, and the strip cigarette packaging mechanism will grab the corresponding number of carton cigarettes for strip cigarette packaging.
[0003] Generally, according to the process requirements, the carton cigarettes need to be in a standing state in the conveying channel. In order to prevent the carton cigarettes from tipping under the thrust of the pusher plate, the size of the conveying channel should be adapted to the size of the carton cigarettes, that is, the surface of the carton cigarettes needs to contact the side wall of the conveying channel. Currently, at least 32 packs of carton cigarettes can be stored between the temporary storage station and the outlet of the conveying channel. That is to say, before the strip cigarette packaging mechanism grabs the corresponding number of carton cigarettes for packaging, the pusher plate needs to push at most 32 packs of carton cigarettes to slide in the temporary storage section. Since the more the number of carton cigarettes, the larger the contact area with the conveying channel and the greater the friction. Therefore, when the pusher plate pushes 32 packs of carton cigarettes at the same time, due to excessive friction, the carton cigarettes are severely deformed, and finally the product quality is reduced. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that the existing packaging machine is easy to cause deformation of carton cigarettes and reduce the product quality. The utility model provides a packaging machine that can prevent the deformation of carton cigarettes, thereby improving the product quality.
[0005] To solve the above technical problems, an embodiment of the utility model discloses a packaging machine for transporting carton cigarettes to a downstream mechanism for packaging into strip cigarettes, including:
[0006] A feeding mechanism for conveying boxed cigarettes to a feeding station;
[0007] A conveying channel, which is provided with an inlet and an outlet. The inlet is close to the feeding station, and the conveying channel is used for conveying boxed cigarettes in a first direction;
[0008] A push plate assembly, including a connecting plate, a first push plate and a second push plate. The first push plate and the second push plate are arranged on the connecting plate at intervals in the first direction; when the push plate assembly moves in the first direction, the first push plate is used to push the boxed cigarettes at the feeding station to a first position, and the second push plate is used to push the boxed cigarettes at the first position to a second position;
[0009] A first driving mechanism for driving the push plate assembly to reciprocate in the first direction;
[0010] A second driving mechanism for driving the push plate assembly to rotate around a rotation axis, so that at least part of the first push plate and the second push plate is located in the conveying channel, or both the first push plate and the second push plate are located outside the conveying channel.
[0011] In the above technical solution, the part between the second position on the conveying channel and the outlet of the conveying channel is a temporary storage section. According to the way that the feeding mechanism only conveys a group of boxed cigarettes (two boxes) at a time, the working process of the packaging machine can be divided into the following steps:
[0012] Step S1a: After the first group of boxed cigarettes are delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly to rotate, so that the first push plate and the second push plate extend into the conveying channel. At this time, the first push plate is located at the feeding station, and the second push plate is located at the first position. Subsequently, the first driving mechanism drives the push plate assembly to move in the first direction. The first push plate pushes the boxed cigarettes at the feeding station to the first position, and at the same time, the second push plate moves to the second position. Then the second driving mechanism drives the push plate assembly to rotate, so that the first push plate and the second push plate are located outside the conveying channel to prevent interference with the boxed cigarettes. Subsequently, the driving mechanism drives the push plate assembly to move in a second direction (opposite to the first direction). The first push plate returns to the feeding station, and the second push plate returns to the first position. At this time, the conveyance of the first group of boxed cigarettes is completed.
[0013] Step S2a: After the second group of boxed cigarettes are delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly to rotate, so that the lower ends of the first push plate and the second push plate rotate into the conveying channel again. Subsequently, the first driving mechanism drives the push plate assembly to move in the first direction. During this process, the first push plate pushes the second group of boxed cigarettes at the feeding station to the first position, and at the same time, the second push plate pushes the first group of boxed cigarettes located at the first position to the second position. Then the second driving mechanism drives the push plate assembly to rotate, so that the first push plate and the second push plate are located outside the conveying channel. Subsequently, the first driving mechanism drives the first push plate to return to the feeding station, and the second push plate returns to the first position. The conveyance of the second group of boxed cigarettes is completed.
[0014] Step S3a: After the third group of cigarette cartons is delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly to rotate, so that the lower ends of the first push plate and the second push plate rotate into the conveying channel again. Then, the first driving mechanism drives the push plate assembly to move in the first direction. During this process, the first push plate pushes the third group of cigarette cartons at the feeding station to the first position, and at the same time, the second push plate pushes the second group of cigarette cartons at the first position to the second position. At this time, the second group of cigarette cartons will contact the first group of cigarette cartons and push the first group of cigarette cartons to move a distance equal to the thickness of one group of cigarette cartons in the direction of the outlet, so that the first group of cigarette cartons enters the temporary storage section. After that, the second driving mechanism drives the push plate assembly to rotate, so that the first push plate and the second push plate are located outside the conveying channel. Then, the first driving mechanism drives the first push plate back to the feeding station, the second push plate back to the first position, and the conveying of the third group of cigarette cartons is completed.
[0015] Step S4a: The subsequent cigarette cartons are conveyed according to the above-mentioned step S3a until the temporary storage section is full of cigarette cartons. The cigarette strip packaging mechanism will grab the corresponding number of cigarette cartons on the temporary storage section for cigarette strip packaging.
[0016] With the above technical solution, in the present application, by setting the first push plate and the second push plate to push the cigarette cartons in the conveying channel in batches, compared with the prior art, the number of cigarette cartons on the temporary storage section can be reduced, so that without changing the structure of the conveying channel, the friction between the cigarette cartons and the conveying channel can be reduced, thereby preventing the cigarette cartons from deforming and improving the product quality.
[0017] Optionally, the push plate assembly further includes:
[0018] A third push plate, which is arranged downstream of the second push plate along the first direction. When the push plate assembly moves in the first direction, the third push plate is used to push the cigarette cartons at the second position to the third position.
[0019] In this technical solution, the part between the third position on the conveying channel and the outlet of the conveying channel is the temporary storage section. Similarly, in the way that the feeding mechanism only conveys one group of cigarette cartons (two cartons) at a time, the conveying processes of the first group of cigarette cartons and the second group of cigarette cartons refer to the aforementioned step S1a and step S2a, and the steps after step S2a refer to the following content:
[0020] Step S3b: When the first push plate pushes the third group of cigarette cartons at the feeding station to the first position and the second push plate pushes the second group of cigarette cartons at the first position to the second position, the third push plate pushes the first group of cigarette cartons at the second position to the third position.
[0021] Step S4b: When the first pusher plate pushes the fourth group of cigarette cartons at the feeding station to the first position, and the second pusher plate pushes the third group of cigarette cartons at the first position to the second position, and the third pusher plate pushes the second group of cigarette cartons at the second position to the third position, at this time, the second group of cigarette cartons will contact the first group of cigarette cartons and push the first group of cigarette cartons to move a distance equal to the thickness of one group of cigarette cartons in the direction of the outlet, so that the first group of cigarette cartons enters the temporary storage section.
[0022] Step S5b: The subsequent cigarette cartons are conveyed according to the above Step S4b until the temporary storage section is filled with cigarette cartons, and the cigarette strip packaging mechanism will grab the corresponding number of cigarette cartons on the temporary storage section for cigarette strip packaging.
[0023] With the above technical solution, in this application, by setting the third pusher plate, the length of the temporary storage section can be further reduced, thereby reducing the number of cigarette cartons that can be accommodated on the temporary storage section, and further reducing the friction between the cigarette cartons and the conveying channel, achieving the effect of preventing the cigarette cartons from deforming and improving the product quality.
[0024] Optionally, the distance between the first pusher plate and the second pusher plate is equal to the distance between the second pusher plate and the third pusher plate.
[0025] Optionally, the side of the first pusher plate for pushing the cigarette cartons is the first working surface, the side of the second pusher plate for pushing the cigarette cartons is the second working surface, the side of the third pusher plate for pushing the cigarette cartons is the third working surface, and the distance between the first working surface and the second working surface is equal to the distance between the feeding station and the first position, and the distance between the second working surface and the third working surface is equal to the distance between the second position and the third position.
[0026] Optionally, the first pusher plate, the second pusher plate and the third pusher plate are all rectangular, and an arc surface is provided at one corner of the first pusher plate, the second pusher plate and the third pusher plate. When the pusher plate assembly rotates between the third position and the fourth position, the arc surface can prevent the first pusher plate, the second pusher plate and the third pusher plate from interfering with the edge of the conveying channel.
[0027] Optionally, the distance between the first pusher plate and the second pusher plate and the distance between the second pusher plate and the third pusher plate are adjustable.
[0028] Optionally, a first long hole and a second long hole are sequentially provided on the connecting plate along the first direction, both the first long hole and the second long hole extend along the first direction, a first threaded hole is provided at the end of the second pusher plate, a second threaded hole is provided at the end of the third pusher plate, and the pusher plate assembly further includes a plurality of bolts. Part of the bolts penetrate through the first long hole and are threadedly connected with the first threaded hole to fix the second pusher plate, and the other part of the bolts penetrate through the second long hole and are threadedly connected with the second threaded hole to fix the third pusher plate.
[0029] Optionally, the material of the pusher plate assembly is stainless steel. Description of the Drawings

[0046] To make the purpose, technical solutions and advantages of the present utility model clearer, the implementation modes of the present utility model will be further described in detail below with reference to the drawings.
[0047] Such as Figure 1 and Figure 2As shown, an embodiment of the present utility model discloses a packaging machine for transporting boxed cigarettes to a downstream mechanism for packaging into cartons of cigarettes. The packaging machine includes a feeding mechanism (not shown in the figure), a conveying channel 2, a push plate assembly 5, a first driving mechanism, and a second driving mechanism. Among them, the feeding mechanism is used to transport boxed cigarettes to a feeding station (such as the area A shown by the dotted line in Figure 2 ), the push plate assembly 5 is used to push the boxed cigarettes on the feeding station into the conveying channel 2. The conveying channel 2 is provided with an inlet 3 and an outlet 4. The inlet 3 is close to the feeding station, and the outlet 4 is close to the downstream mechanism. The conveying channel 2 is used to transport boxed cigarettes along a first direction (such as the X direction shown in Figure 1 and Figure 2 ), facilitating the downstream mechanism to grab a certain number of boxed cigarettes from the conveying channel 2 for packaging into cartons of cigarettes. The push plate assembly 5 includes a connecting plate 6, a first push plate 7, and a second push plate 8. The first push plate 7 and the second push plate 8 are arranged on the connecting plate 6 at intervals along the first direction. When the push plate assembly 5 moves along the first direction, the first push plate 7 is used to push the boxed cigarettes on the feeding station to a first position on the conveying channel 2 (such as the area B shown by the dotted line in Figure 2 ), and the second push plate 8 is used to push the boxed cigarettes at the first position to a second position on the conveying channel 2 (such as the area C shown by the dotted line in Figure 2 ), so as to realize the batch and continuous transportation of boxed cigarettes. The first driving mechanism is used to drive the push plate assembly 5 to reciprocate along the first direction, and the second driving mechanism is used to drive the push plate assembly 5 to rotate around the rotation axis, so that at least part of the first push plate 7 and the second push plate 8 is located inside the conveying channel 2, or both the first push plate 7 and the second push plate 8 are located outside the conveying channel 2. Among them, the rotation axis is the axis of the connecting rod 1.
[0048] The present application does not limit the forms of the first driving mechanism and the second driving mechanism. In some embodiments, as shown in Figure 1 , the first driving mechanism and the second driving mechanism can be an integral cam-link mechanism. The connecting rod 1 in the cam-link mechanism is directly or indirectly connected to the connecting plate 6. The cam-link mechanism drives the push plate assembly 5 to reciprocate along the first direction and drives the push plate assembly 5 to rotate around the rotation axis.
[0049] In the above technical solution, the part between the second position on the conveying channel 2 and the outlet 4 of the conveying channel 2 is a temporary storage section (such as the line segment F shown in Figure 2 ). According to the way that the feeding mechanism only transports a group of boxed cigarettes (usually two boxes) at a time, the working process of the packaging machine can be divided into the following steps:
[0050] Step S1a: Refer to Figure 2, after the first group of cigarette cartons (denoted as cigarette carton e) are delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly 5 to rotate, so that the lower ends of the first push plate 7 and the second push plate 8 extend into the conveying channel 2. At this time, the first push plate 7 is located at the feeding station, and the second push plate 8 is located at the first position. Subsequently, the first driving mechanism drives the push plate assembly 5 to move in the first direction. Refer to Figure 3 , the first push plate 7 pushes the cigarette carton at the feeding station to the first position, and at the same time, the second push plate 8 moves to the second position. Then the second driving mechanism drives the push plate assembly 5 to rotate, so that the first push plate 7 and the second push plate 8 are located outside the conveying channel 2 to prevent interference with the cigarette cartons. Subsequently, the driving mechanism drives the push plate assembly 5 to move in the second direction (opposite to the first direction), the first push plate 7 returns to the feeding station, and the second push plate 8 returns to the first position. At this time, the conveying of the first group of cigarette cartons is completed.
[0051] Step S2a: After the second group of cigarette cartons are delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly 5 to rotate, so that the lower ends of the first push plate 7 and the second push plate 8 rotate into the conveying channel 2 again. Subsequently, the first driving mechanism drives the push plate assembly 5 to move in the first direction. During this process, refer to Figure 4 , the first push plate 7 pushes the second group of cigarette cartons (denoted as cigarette carton f) at the feeding station to the first position, and at the same time, the second push plate 8 pushes the first group of cigarette cartons at the first position to the second position. Then the second driving mechanism drives the push plate assembly 5 to rotate, so that the first push plate 7 and the second push plate 8 are located outside the conveying channel 2. Subsequently, the first driving mechanism drives the first push plate 7 back to the feeding station, and the second push plate 8 returns to the first position. The conveying of the second group of cigarette cartons is completed.
[0052] Step S3a: After the third group of cigarette cartons (denoted as cigarette carton g) are delivered to the feeding station by the feeding mechanism, the second driving mechanism drives the push plate assembly 5 to rotate, so that the lower ends of the first push plate 7 and the second push plate 8 rotate into the conveying channel 2 again. Subsequently, the first driving mechanism drives the push plate assembly 5 to move in the first direction. During this process, refer to Figure 5 , the first push plate 7 pushes the third group of cigarette cartons at the feeding station to the first position, and at the same time, the second push plate 8 pushes the second group of cigarette cartons at the first position to the second position. At this time, the second group of cigarette cartons will contact the first group of cigarette cartons and push the first group of cigarette cartons to move a distance equal to the thickness of one group of cigarette cartons in the direction of the outlet 4, so that the first group of cigarette cartons enter the temporary storage section. Then the second driving mechanism drives the push plate assembly 5 to rotate, so that the first push plate 7 and the second push plate 8 are located outside the conveying channel 2. Subsequently, the first driving mechanism drives the first push plate 7 back to the feeding station, and the second push plate 8 returns to the first position. The conveying of the third group of cigarette cartons is completed.
[0053] Step S4a: The subsequent cigarette cartons are conveyed according to the above-mentioned step S3a. Refer to Figure 6, until the temporary storage section is filled with boxed cigarettes, the carton packaging mechanism will grab the corresponding number (usually 10 packs) of boxed cigarettes on the temporary storage section for carton packaging.
[0054] Adopting the above technical solution, in this application, the first push plate 7 and the second push plate 8 are arranged to push the boxed cigarettes in the conveying channel 2 in batches. Compared with the prior art where 32 packs of boxed cigarettes are stored in the temporary storage section, the number of boxed cigarettes on the temporary storage section in this application can be reduced (for example, Figure 6 the temporary storage section in [reference] can store up to seven groups of boxed cigarettes, that is, 14 packs of boxed cigarettes), so that without changing the structure of the conveying channel 2, the friction between the boxed cigarettes and the conveying channel 2 can be reduced, thereby preventing the boxed cigarettes from deforming and improving the product quality.
[0055] Optionally, as Figure 1 shown, the push plate assembly 5 further includes: a third push plate 9, which is arranged downstream of the second push plate 8 along the first direction. When the push plate assembly 5 moves along the first direction, the third push plate 9 is used to push the boxed cigarettes in the second position to the third position (as shown in the area D indicated by the dotted line in Figure 7 ).
[0056] When the push plate assembly 5 includes the third push plate 9, the part between the third position on the conveying channel 2 and the outlet 4 of the conveying channel 2 is the temporary storage section. It also follows the method that the feeding mechanism only conveys one group of boxed cigarettes (two boxes) at a time. For the conveying processes of the first group of boxed cigarettes and the second group of boxed cigarettes, refer to the aforementioned step S1a and step S2a. The steps after step S2a are as follows:
[0057] Step S3b: Refer to Figure 7 , when the first push plate 7 pushes the third group of boxed cigarettes at the feeding station to the first position and the second push plate 8 pushes the second group of boxed cigarettes at the first position to the second position, the third push plate 9 pushes the first group of boxed cigarettes at the second position to the third position.
[0058] Step S4b: Refer to Figure 8 , when the first push plate 7 pushes the fourth group of boxed cigarettes at the feeding station to the first position and the second push plate 8 pushes the third group of boxed cigarettes at the first position to the second position, and the third push plate 9 pushes the second group of boxed cigarettes at the second position to the third position, at this time, the second group of boxed cigarettes will contact the first group of boxed cigarettes and push the first group of boxed cigarettes to move a distance equal to the thickness of one group of boxed cigarettes in the direction of the outlet 4, so that the first group of boxed cigarettes enters the temporary storage section.
[0059] Step S5b: The subsequent boxed cigarettes are conveyed according to the above step S4b. Refer to Figure 9 , until the temporary storage section is filled with boxed cigarettes. Exemplarily, as Figure 9 shown, the temporary storage section can store up to 12 packs of boxed cigarettes at most. After that, the carton packaging mechanism will grab the corresponding number of boxed cigarettes on the temporary storage section for carton packaging.
[0060] With the above technical solution, the present application can further reduce the length of the temporary storage section by setting the third push plate 9, thereby reducing the number of cigarette cartons that can be accommodated on the temporary storage section, further reducing the friction between the cigarette cartons and the conveying channel 2, achieving the effect of preventing the cigarette cartons from deforming and improving the product quality. At the same time, at most six groups of cigarette cartons, that is, 12 packs of cigarette cartons, can be stored on the temporary storage section, which is more than 10 packs. After the carton packing mechanism grabs 10 packs of cigarette cartons, there are still two packs of cigarette cartons stored on the temporary storage section, which can provide a certain supporting force for the cigarette cartons subsequently input into the temporary storage section, preventing the subsequent cigarette cartons from toppling under the action of inertia.
[0061] Optionally, as Figure 7 shown, the side of the first push plate 7 for pushing the cigarette cartons is the first working surface 10, the side of the second push plate 8 for pushing the cigarette cartons is the second working surface 11, the side of the third push plate 9 for pushing the cigarette cartons is the third working surface 12, and the distance between the first working surface 10 and the second working surface 11 (as Figure 7 shown by the dimension L1 in Figure 7 ) is equal to the distance between the front end of the feeding station and the front end of the first position (as Figure 7 shown by the dimension L2 in Figure 7 ), that is, L1 = L2. Preferably, the distance between the first push plate 7 and the second push plate 8 is equal to the distance between the second push plate 8 and the third push plate 9, that is, the distance between the first working surface 10 and the second working surface 11 (as Figure 7 shown by the dimension L1 in Figure 7 ) is equal to the distance between the second working surface 11 and the third working surface 12 (as Figure 7 shown by the dimension L3 in Figure 7 ), that is, L1 = L3. From this, it can be deduced that L1 = L2 = L3. Further, the distance between the second working surface 11 and the third working surface 12 (as Figure 7 shown by the dimension L3 in Figure 7 ) is equal to the distance between the second position and the third position (as Figure 7 shown by the dimension L4 in ), that is, L3 = L4. From this, it can be deduced that L1 = L2 = L3 = L4. With such a setting, the first push plate 7 can just push the cigarette cartons on the feeding station to the first position, the second push plate 8 can just push the cigarette cartons in the first position to the second position, and the third push plate 9 can just push the cigarette cartons in the second position to the third position, thus ensuring the continuity of conveying.
[0062] Optionally, as Figure 10 shown, the first push plate 7, the second push plate 8 and the third push plate 9 are all rectangular, and an arc surface 13, which can also be called an avoidance surface, is provided at one corner of the lower ends of the first push plate 7, the second push plate 8 and the third push plate 9. The arc surface 13 is arranged close to the side wall of the conveying channel 2. When the push plate assembly 5 rotates along Figure 10 the R1 direction in
[0063] , the arc surface 13 can prevent the first push plate 7, the second push plate 8 and the third push plate 9 from interfering with the edge of the conveying channel 2.
[0063] Optionally, the distance between the first push plate 7 and the second push plate 8 and the distance between the second push plate 8 and the third push plate 9 are adjustable, so as to adapt to the thickness of cigarette boxes of different specifications and expand the application range of the device.
[0064] Specifically, as Figure 10 shown, the connecting plate 6 includes a first plate body 18 and a second plate body 19 which are connected. One end of the first plate body 18 is connected to the connecting rod 1 of the crank and connecting rod mechanism, and the first push plate 7 is connected to the other end of the first plate body 18. The second plate body 19 extends in the first direction. The first push plate 7, the second push plate 8 and the third push plate 9 extend in parallel and are all perpendicular to the first direction. Along the first direction, a first strip-shaped hole 14 and a second strip-shaped hole 15 are sequentially arranged on the second plate body 19. The number of the first strip-shaped hole 14 and the second strip-shaped hole 15 is two each and both extend in the first direction. A first threaded hole (not shown in the figure) is provided at the upper end of the second push plate 8, and a second threaded hole (not shown in the figure) is provided at the upper end of the third push plate 9. The push plate assembly 5 further includes a plurality of bolts.
