Abstract
Description
Technical Field
[0001] This application relates to the technical field of cigarette pack production, and particularly to a cigarette pack packaging machine. Background Art
[0002] The function of the fourth wheel is to turn the sulfuric acid paper cigarette pack by 180° and then output the sulfuric acid paper cigarette pack into the small box on the small box filling machine. At the cigarette pack output station, the small box is lifted to the overpass socket by the lifting device, so that the guiding piece installed at the overpass socket enters the small box in advance. Then, the pushing cigarette board directly above the output station pushes the sulfuric acid paper cigarette pack at this station downward, so that the sulfuric acid paper cigarette pack can be limited and guided by the guiding piece when falling from the overpass socket, and thus can fall into the small box smoothly and reliably.
[0003] In the actual production process, since the guiding piece at the overpass socket is a vulnerable part, it needs to be replaced frequently. When replacing the guiding piece, it is necessary to disassemble components such as the pushing cigarette board, the upper arc guiding plate and the die box, which is rather cumbersome. Moreover, after replacing the guiding piece, the overpass position needs to be adjusted again, so the maintenance process takes a long time and affects the efficiency.
[0004] It should be noted here that the statements in this background art section only provide background art related to this application and do not necessarily constitute prior art. Utility Model Content
[0005] This application provides a cigarette pack packaging machine to improve the convenience of replacing the guiding piece at the overpass socket.
[0006] This application provides a cigarette pack packaging machine, including a transfer wheel and an overpass device. The transfer wheel is rotatably arranged and is used to carry and transfer cigarette packs during rotation. On the rotation path of the cigarette pack, the cigarette pack packaging machine has an input station and an output station. At the input station, the cigarette pack is placed on the transfer wheel. At the output station, the cigarette pack is separated from the transfer wheel and collected. The overpass device is arranged below the transfer wheel in the height direction. The overpass device includes a first plate section, a second plate section and a connecting plate. The connecting plate is used to connect the first plate section and the second plate section. An opening is arranged on the second plate section. The opening penetrates in the thickness direction of the second plate section. On the rotation path, the first plate section is located upstream of the output station to receive the dropped cigarette pack during the transfer of the cigarette pack. The opening is aligned with the output station so that the cigarette pack passes through the opening when separated from the transfer wheel.
[0007] In some embodiments, both ends of the connecting plate are detachably connected to the first plate section and the second plate section respectively.
[0008] In some embodiments, the cross-sectional shape of the connecting plate is a right trapezoid. The straight waist of the right trapezoid is connected to the first plate section, and the oblique waist of the right trapezoid is connected to the second plate section.
[0009] In some embodiments, the extension line of one end of the first plate segment for connecting with the connecting plate passes through the axis of rotation of the transfer wheel.
[0010] In some embodiments, the transfer wheel includes a wheel body and a plurality of receiving frames uniformly arranged around the edge of the wheel body. The receiving frames are used to receive cigarette packs. Adjacent two receiving frames are spaced at a set angle in the circumferential direction. The transfer wheel is configured to rotate a set angle at a time, and before the transfer wheel starts to rotate, one of the plurality of receiving frames is exactly aligned with the opening. The connecting plate is arranged between the opening and the receiving frame adjacent to the front side of the opening in the rotation path.
[0011] In some embodiments, the extension line of one end of the first plate segment for connecting with the connecting plate passes through the axis of rotation of the transfer wheel. The first plate segment is an arc-shaped plate. The arc-shaped plate has an inner arc side close to the axis of rotation of the transfer wheel and an outer arc side far from the axis of rotation of the transfer wheel. In the rotation plane of the transfer wheel, the receiving frame adjacent to the front side of the opening in the rotation path intersects with the inner arc side at a first intersection point and a second intersection point respectively. The second intersection point is closer to the opening than the first intersection point, and the extension line also passes through the second intersection point.
[0012] In some embodiments, the bridging device further includes a positioning pin and a positioning hole. One of the positioning pin and the positioning hole is arranged on the connecting plate. The other of the positioning pin and the positioning hole is arranged on the first plate segment and the second plate segment. The positioning pin is used to form a concave-convex fit with the positioning hole.
[0013] In some embodiments, the bridging device further includes a fastener. The fastener is configured to connect the first plate segment and the connecting plate, and / or connect the second plate segment and the connecting plate.
[0014] In some embodiments, the transfer wheel includes a No. 4 wheel.
[0015] In some embodiments, the cigarette pack packaging machine further includes an upper guide plate. The upper guide plate is located above the transfer wheel in the height direction. The upper guide plate is arranged in the rotation path. The upper guide plate is used to contact the upper surface of the cigarette pack during the process of transferring the cigarette pack to limit the cigarette pack in the height direction.
[0016] Based on the technical solution provided by this application, a cigarette packet packaging machine includes a transfer wheel and a bridge device. The transfer wheel is rotatably arranged and is used to carry and transfer cigarette packets during rotation. On the rotation path of the cigarette packets, the cigarette packet packaging machine has an input station and an output station. At the input station, the cigarette packets are placed on the transfer wheel. At the output station, the cigarette packets are separated from the transfer wheel and collected. The bridge device is arranged below the transfer wheel in the height direction. The bridge device includes a first plate section, a second plate section, and a connecting plate. The connecting plate is used to connect the first plate section and the second plate section. An opening is provided on the second plate section. The opening penetrates in the thickness direction of the second plate section. On the rotation path, the first plate section is located upstream of the output station to receive the dropped cigarette packets during the transfer of the cigarette packets. The opening is aligned with the output station so that the cigarette packets pass through the opening when separated from the transfer wheel. When replacing the guiding piece, only the second plate section needs to be disassembled, so that the second plate section is separated from the connecting plate, and after the replacement is completed, the second plate section is reconnected to the connecting plate. There is no need to adjust the first plate section. Therefore, fewer components need to be disassembled during the entire replacement process, and the steps are also simpler and more convenient, taking less time and improving production efficiency.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part rather than all of the embodiments of the present application. The description of at least one exemplary embodiment is actually illustrative only and in no way limits the present application and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.
[0026] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the description. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0027] For the sake of description, spatial relative terms, such as "above...", "on top of...", "on the upper surface of...", "overhead", etc., may be used here to describe the spatial position relationship of one device or feature to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above..." can include both the orientation of "above..." and "below...". The device may also be positioned in other different ways and corresponding interpretations may be made for the spatial relative descriptions used here.
[0028] Figure 1The schematic diagram of the No. 4 wheel 1 of the existing cigarette packing machine is shown. The No. 4 wheel 1 has several mold boxes for accommodating cigarette packs, wherein A1 is the input station, where the cigarette packs are placed in the mold box at this station, and then as the No. 4 wheel 1 rotates counterclockwise, the cigarette packs arrive at the rejection station A3, where the cigarette pack packaging machine will detect whether the quality of the cigarette packs is qualified, and if not, the cigarette packs in the mold box will be rejected. If the quality of the cigarette packs is qualified, the cigarette packs continue to rotate counterclockwise to the output station A2, at which the cigarette push plate 5 moves from top to bottom to apply force to the cigarette packs in the mold box, so that the cigarette packs are separated from the mold box, wherein a bridge 2' is provided on the lower side of the No. 4 wheel 1, and the bridge 2' is used to receive the cigarette packs that fall off the mold box during the process of transporting the cigarette packs, and a hollow sleeve is provided at the position of the bridge corresponding to the output station A2, so that the cigarette packs fall through the sleeve to be collected when they are separated from the mold box at the output station A2.
[0029] In order to make the cigarette pack fall more stably at the output station A2 and ensure that the cigarette pack can enter the collection device smoothly, refer to Figure 2 The cigarette packing machine is usually also equipped with a guide plate 3 and a lifting device 4. The guide plate 3 is arranged around the inner wall surface of the sleeve and extends downward a certain distance relative to the sleeve. The lifting device 4 is used to lift the cigarette pack collecting device so that the cigarette pack collecting device enters the area enclosed by the guide plate 3. Therefore, during the falling process of the cigarette pack, the guide plate can be used to limit and guide the cigarette pack to ensure that the cigarette pack enters the cigarette pack collecting device smoothly.
[0030] The inventors of the present application have discovered that the guide plate is a wearing part and therefore needs to be replaced frequently. When replacing the guide plate, it is necessary to disassemble components such as the bridge, mold box, and cigarette pusher plate. The disassembly process is cumbersome, and after replacing the guide plate, it is necessary to adjust the position of the bridge. Therefore, the whole process is time-consuming, affecting production efficiency.
[0031] For this purpose, refer to Figure 1 and 5, some embodiments of the present application provide a cigarette pack packaging machine, including a transfer wheel 1 and a bridging device 2. The transfer wheel 1 is rotatably arranged, and the transfer wheel 1 is used to carry and transfer cigarette packs during rotation. On the rotation path of the cigarette pack, the cigarette pack packaging machine has an input station A1 and an output station A2. At the input station A1, the cigarette pack is placed on the transfer wheel 1. At the output station A2, the cigarette pack is separated from the transfer wheel 1 and collected. The bridging device 2 is arranged on the lower side of the transfer wheel 1 in the height direction. The bridging device 2 includes a first plate section 21, a second plate section 22, and a connecting plate 23. The connecting plate 23 is used to connect the first plate section 21 and the second plate section 22. An opening 24 is provided on the second plate section 22. The opening 24 penetrates in the thickness direction of the second plate section 22. On the rotation path, the first plate section 21 is located upstream of the output station A2 to receive the dropped cigarette pack during the transfer of the cigarette pack. The opening 24 is aligned with the output station A2 so that the cigarette pack passes through the opening when separated from the transfer wheel 1.
[0032] When replacing the guide piece, only the second plate section 22 needs to be disassembled to separate the second plate section 22 from the connecting plate 23, and then reconnect the second plate section 22 to the connecting plate 23 after replacement. There is no need to adjust the first plate section 22. Therefore, fewer components need to be disassembled during the entire replacement process, and the steps are also simpler and more convenient, taking less time and improving production efficiency.
[0033] In some embodiments, both ends of the connecting plate 23 are detachably connected to the first plate section 21 and the second plate section 22 respectively. Specifically, the first plate section 21 and the second plate section 22 are respectively connected to both ends of the connecting plate 23 in the direction of the rotation path, so that the interval between the first plate section 21 and the second plate section 22 can be increased, facilitating disassembly and improving the convenience of disassembly.
[0034] Reference Figure 6 , in some embodiments, the cross-sectional shape of the connecting plate 23 is a right trapezoid. The straight waist of the right trapezoid is connected to the first plate section 21. The oblique waist of the right trapezoid is connected to the second plate section 22. The upper base and the lower base of the right trapezoid are smoothly and transitionally connected to the first plate section 21 and the second plate section 22 respectively, reducing the occurrence of sharp edges at the connection and improving safety.
[0035] Reference Figure 1 , in some embodiments, the transfer wheel 1 includes a wheel body 11 and a plurality of receiving frames 12 (i.e., mold boxes) evenly arranged around the edge of the wheel body 11. The receiving frames 12 are used to receive cigarette packs. Adjacent two receiving frames 12 are spaced at a set angle in the circumferential direction. The transfer wheel 1 is configured to rotate a set angle each time, and before the transfer wheel starts to rotate, one of the plurality of receiving frames 12 is exactly aligned with the opening 24. The connecting plate 23 is arranged between the opening 24 and the receiving frame adjacent to the opening 24 on the front side in the rotation path.
[0036] The rotation of the transfer wheel 1 is discontinuous. For example, the transfer wheel 1 includes 8 evenly distributed receiving frames 12, and any two adjacent receiving frames 12 are circumferentially spaced by 45°. The rotating wheel is configured to rotate 45° at a time. That is to say, for a certain receiving frame 12, it completes a full circle of movement after the rotating wheel 1 rotates 8 times. Therefore, before each receiving frame 12 reaches the output station A2, it stays at a position circumferentially spaced 45° from the output station A2. By arranging the connecting plate 23 between this position and the opening 24, it can be ensured that when disassembling the second plate segment 22, only the receiving frame 12 located at the opening 24 needs to be disassembled, and the adjacent receiving frames 12 do not need to be disassembled, increasing the convenience of disassembly.
[0037] Considering that there are many components in the cigarette packet packaging machine, in order to reduce the space occupied by adding the connecting plate and avoid interference between the connecting plate and other components of the packaging machine, the existing bridge is cut, and a connection part is added at the cutting position. The selection of the cutting position is described below.
[0038] Reference Figure 3 and Figure 4 In some embodiments, the extension line of one end of the first plate segment 21 for connecting with the connecting plate 23 passes through the axis of rotation of the transfer wheel 1. The first plate segment 21 is an arc-shaped plate. The arc-shaped plate has an inner arc edge close to the axis of rotation of the transfer wheel 1 and an outer arc edge far from the axis of rotation of the transfer wheel 1. In the rotation plane of the transfer wheel 1, the receiving frame 12 adjacent to the front side of the opening 24 on the rotation path intersects with the inner arc edge at the first intersection point P1 and the second intersection point P2 respectively. The second intersection point P2 is closer to the opening 24 than the first intersection point P1, and the extension line also passes through the second intersection point P2.
[0039] The extension line is the cutting line. Such a setting can keep the cutting line away from the opening 24, increase the contact area between the second plate segment 22 and the connecting plate 23, and improve the connection stability between the second plate segment 22 and the connecting plate 23.
[0040] Reference Figure 5 In some embodiments, the bridge device 2 further includes a positioning pin 25 and a positioning hole. One of the positioning pin 25 and the positioning hole is arranged on the connecting plate 23. The other of the positioning pin 25 and the positioning hole is arranged on the first plate segment 21 and the second plate segment 22. The positioning pin 25 is used to form a concave-convex fit with the positioning hole. This facilitates positioning when connecting the first plate segment 21, the second plate segment 22, and the connecting plate 23, and improves the assembly efficiency.
[0041] In some embodiments, the bridge device 2 further includes a fastener 26. The fastener 26 is configured to connect the first plate segment 21 and the connecting plate 23, and to connect the second plate segment 22 and the connecting plate 23.
[0042] Specifically, the fastener 26 includes a threaded connector, and threaded holes are provided at corresponding positions of the first plate segment 21 and the connecting plate 23, and at corresponding positions of the second plate segment 22 and the connecting plate 23. The threaded connector passes through the threaded holes to connect and fasten the first plate segment 21 and the connecting plate 23, and the second plate segment 22 and the connecting plate 23, thereby improving the connection stability.
[0043] refer to Figure 1 In some embodiments, the reject station A3 of the cigarette packing machine is adjacent to the input station A1. From the reject station A3 to the output station A2, the transfer wheel needs to transfer three times, that is, the reject station A3 and the output station A2 are circumferentially spaced 135° apart. In other words, there are two stations between the reject station A3 and the output station A2 for the accommodating frame 12 to pause (for ease of description, these two stations are named the first transfer station and the second transfer station). The first plate section 21 is arranged between the first transfer station and the second transfer station to receive the cigarette packs that fall during the transfer process.
[0044] In some embodiments, the cigarette packing machine further includes an upper guide plate 6. The upper guide plate 6 is located on the upper side of the transfer wheel 1 in the height direction, and the upper guide plate 6 is arranged on the rotation path. The upper guide plate 6 is used to contact the upper surface of the cigarette pack during the transfer of the cigarette pack to limit the cigarette pack in the height direction. The upper guide plate 6 is arranged between the first transfer station and the second transfer station, so that the upper guide plate 6 can limit the cigarette pack, and there is no need to remove the upper guide plate 6 when replacing the guide plate 3, because the upper guide plate 6 does not extend to the opening 24, which increases convenience.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
