Description

Technical Field

[0001] This invention relates to the field of cigarette packaging machine technology, and in particular to a pushing device for a cigarette packaging machine. Background Technology

[0002] The YB65 packaging machine is used to connect the two layers of cigarette packs conveyed by the YB55. Each layer has 5 cigarette packs, for a total of 10 cigarette packs. The YB55 pushes the neatly stacked 10 cigarette packs to the fixed station of the YB65 packaging machine, and then pushes the neatly stacked 10 cigarette packs into the carton folding station for folding and packaging via a pusher plate structure.

[0003] For example, Chinese Patent (Application No.: 202111618456.0) discloses a pushing mechanism for a cigarette packaging machine, which includes a push plate assembly, a transmission assembly, and a drive assembly. The transmission assembly includes a horizontal rotating shaft and a push rod. The push rod includes a first rod body and a second rod body. The horizontal rotating shaft includes a first shaft body and a second shaft body. A deceleration assembly is provided between the first rod body and the second rod body. The deceleration assembly includes a first elastic element. The two ends of the first elastic element are fixedly connected to the first rod body and the second rod body, respectively. A stop block is provided at one end of the second rod body near the first rod body. One-way gears are provided at both ends of the stop block. A limit block is slidably provided near the one-way gears on the stop block. A limit plate is provided on the limit block. The side of the limit plate near the push plate assembly abuts against the teeth of the one-way gear.

[0004] However, when this structure pushes the cigarette packs, there are two movements: one is the continuous pushing of the cigarette packs along the horizontal direction, and the other is the pushing of multiple cigarette packs as a group along the vertical direction for packaging. Since the speed of the cigarette packs remains constant, the length of the rotating end of the pushing mechanism needs to be shortened to prevent it from hitting the newly entered cigarette packs in the horizontal direction when the cigarette packs are pushed back. This would result in insufficient contact area between the end of the rotating end and the cigarette pack at the end, so that the end of the rotating end can only push the cigarette pack to half the width of the end cigarette pack, which would make the cigarette pack at the end prone to tipping over. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a pushing device for a cigarette packaging machine, which solves the problem mentioned in the background art that the end of the rotating end and the end cigarette pack in the prior art have insufficient contact surface, so that the end of the rotating end can only push to half the width of the end cigarette pack, which makes the end cigarette pack easy to tip over.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] In a first aspect, a packing device for a cigarette packaging machine is provided, the packing device comprising:

[0008] The base is slidably mounted on the base plate of the cigarette packaging machine;

[0009] A fixed push rod is fixed on one side of the base that pushes the cigarette pack.

[0010] A rotating push rod is arranged side by side with the fixed push rod. The rotating push rod includes a sliding member, a transition member, a telescopic member, and a connecting shaft. The sliding member, the transition member, and the telescopic member are arranged sequentially away from the fixed push rod. The transition member is hinged to the base and a first elastic reset member is installed between the transition member and the base. The connecting shaft passes through the transition member and is axially movable. The two ends of the connecting shaft are fixed to the sliding member and the telescopic member, respectively. A portion of the sliding member is slidably mounted on the base. When the transition member deflects relative to the base, driving the sliding member to slide away from the fixed push rod, the sliding member gradually moves away from the transition member. The telescopic member gradually moves closer to the transition member under the drive of the connecting shaft.

[0011] A rotary transmission assembly is used to drive the rotary push rod to deflect during the reset of the base. The rotary transmission assembly includes a connector, a flipping component, and a blocking component. The connector is fixed to the transition component. The flipping component is hinged to the connector and a second elastic reset component is installed between the connector and the connector. The blocking component is fixed on the movement trajectory of the flipping component.

[0012] Furthermore, according to claim 1, the pusher device for a cigarette packaging machine is characterized in that the base has an arc-shaped groove, the sliding member is provided with a sliding rod, and the sliding rod is slidably installed in the groove.

[0013] Furthermore, the slide rod passes through the slide groove and extends out of the slide groove at both ends. The sliding member has a U-shaped structure, with the top two sides of the U-shape of the sliding member connected to the two ends of the slide rod, and the bottom end of the U-shape of the sliding member fixed to the connecting shaft.

[0014] Furthermore, the side of the slider is Z-shaped, with the outer side contacting the cigarette pack and the inner end connected to the slide rod.

[0015] Furthermore, the transition member includes a pusher plate that contacts the cigarette pack and a hinge plate that is vertically fixed to the pusher plate. A first pin is provided at one end of the hinge plate away from the pusher plate, and the hinge plate is hinged to the base through the first pin. A first limiting plate is fixed on the side of the hinge portion of the base and the hinge plate away from the slide groove. The first limiting plate is used to limit the rotation range of the hinge plate.

[0016] Furthermore, the first elastic reset element is a first torsion spring, which is sleeved on the first pin, with one end of the first torsion spring abutting against the hinge plate and the other end of the first torsion spring abutting against the base.

[0017] Furthermore, the lowest point of the connector, the flipping member, and the blocking member are all higher than the highest point of the cigarette pack; a mounting plate is fixed on the connector, and the mounting plate is fixed to the hinge plate near the first pin; a mounting bracket is fixed on the blocking member, and the blocking member is fixed to the base plate of the cigarette packaging machine by the mounting bracket.

[0018] Furthermore, a second pin is provided at the end of the connector away from the mounting plate, and the connector and the flipping member are hinged together by the second pin; a second limiting plate is fixed on the hinge portion of the connector and the flipping member facing the smoke pusher plate, and the second limiting plate is used to limit the rotation range of the flipping plate.

[0019] Furthermore, the second elastic reset member is a second torsion spring, which is sleeved on the second pin, with one end of the second torsion spring abutting against the connecting member and the other end of the second torsion spring abutting against the flipping member.

[0020] The beneficial effects of this invention are:

[0021] This invention, by setting up a base, a fixed push rod, a rotating push rod, and a rotating transmission assembly, not only extends the length of the rotating push rod, allowing the rotating push rod and the fixed push rod to fully contact the cigarette pack; but also shortens the length of the rotating push rod when it rotates and retracts, reducing the risk of the rotating push rod overturning the cigarette packs that are subsequently entering the "to be pushed cigarette position" when it retracts, thus ensuring the smooth progress of the cigarette pushing process.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Currently, the width of a single pack of cigarettes is 66mm, the width of the fixed push rod 20 is 104mm, and the existing width of the rotating push rod 30 is 156mm; while in the old structure, the width of the rotating push rod 30 was 143mm. It can be seen that, compared to the original structure, the existing structure increases the width of the rotating push rod 30 in pushing the cigarettes, and the contact width between the rotating push rod 30 and the cigarette pack at the end is increased (by 13mm), effectively preventing the cigarette pack at the end from tipping over during the pushing process and ensuring smooth progress.

[0029] When pushing the cigarette pack, the direction of movement of the cigarette pack being pushed into the "smoke pack to be pushed position" (the position where the cigarette pack is pushed by the cigarette pack) is set to horizontal. In this direction, the speed of pushing the cigarette pack by the machine remains constant. The direction of movement of the cigarette pack being pushed by the cigarette pack by the cigarette pack is set to vertical. The two directions are perpendicular to each other. As the cigarette packs are gradually pushed laterally into the "push-to-push position," the longitudinally moving push mechanism moves towards the cigarette packs, pushing the first group of cigarette packs backward so that the packaging mechanism can package them. At this time, the push device needs to retract to avoid the newly entered cigarette packs in the "push-to-push position." Since the rotating push rod 30 is closer to the newly moved cigarette packs in the "push-to-push position," the rotating push rod 30 will rotate under the action of the rotating transmission component 40 to avoid the newly entered cigarette packs. By setting a telescopic member 33 that can be pulled back by the connecting shaft 34, the length of the rotating push rod 30 in the push direction when it rotates back is reduced compared to the original structure. That is, it is equivalent to appropriately increasing the length of the rotating push rod 30 in the push direction to ensure sufficient contact width between the rotating push rod 30 and the end cigarette pack, ensuring the stability of the end cigarette pack during the push process of the push mechanism, reducing the probability of the end cigarette pack tipping over, reducing the number of downtimes, and improving the efficiency of the push-to-push packaging. In addition, after the rotating push rod 30 leaves the position to be pushed and returns to the initial position, it rotates again under the action of the first elastic reset member 35 to keep parallel with the fixed push rod 20. Then the rotating push rod 30 and the fixed push rod 20 will move towards the tobacco pack to perform the next pushing action.

[0030] like Figures 1 to 4 As shown in the figure, this application provides a pushing device for a cigarette packaging machine, which is applied to a cigarette packaging machine. The pushing device includes a base 10, a fixed push rod 20, a rotating push rod 30, and a rotating transmission assembly 40. The base 10 is slidably mounted on the base plate of the cigarette packaging machine. The sliding direction of the base 10 is the longitudinal direction mentioned above. The base 10 can be driven by a cylinder, an electric push rod, or other driving components to achieve the sliding function.

[0031] The fixed push rod 20 is a rectangular thin block. The fixed push rod 20 is fixed on the side of the base 10 that pushes the cigarette pack. The side of the fixed push rod 20 away from the base 10 can contact part of the cigarette pack in the "to be pushed cigarette position".

[0032] The rotating push rod 30 and the fixed push rod 20 are arranged side by side, and the rotating push rod 30 and the fixed push rod 20 cooperate to push all the cigarette packs in the "to-push cigarette position". The rotating pusher includes a sliding member 31, a transition member 32, a telescopic member 33 and a connecting shaft 34. Among them, the sliding member 31, the transition member 32 and the telescopic member 33 are arranged sequentially in the direction away from the fixed push rod 20. The sliding member 31, the transition member 32 and the telescopic member 33 are the three pushing parts of the rotating push rod 30, which cooperate with the fixed push rod 20 and directly contact the cigarette packs. Furthermore, the parts of the three pushing parts of the sliding member 31, the transition member 32 and the telescopic member 33 that directly contact the cigarette packs are all rectangular thin blocks.

[0033] The transition member 32 is hinged to the base 10, and can deflect within a certain range relative to the base 10. Through the hinge between the transition member 32 and the base 10, the entire rotating push rod 30 can deflect relative to the base 10 to avoid subsequent cigarette packs entering the "to-push cigarette position". Furthermore, a first elastic reset member 35 is installed between the transition member 32 and the base 10, which resets the rotating push rod 30 after its deflection is complete.

[0034] The connecting shaft 34 passes through the transition member 32 along its length and can move along its own axial direction. Both ends of the connecting shaft 34 are fixed to the sliding member 31 and the telescopic member 33, respectively. Part of the sliding member 31 is slidably mounted on the base 10. When the transition member 32 deflects relative to the base 10, it drives the sliding member 31 to slide away from the fixed push rod 20. During this process, the sliding member 31 gradually moves away from the transition member 32, while the telescopic member 33 gradually approaches the transition member 32 under the influence of the connecting shaft 34. Compared to the original design, this not only extends the length of the rotating push rod 30, allowing it and the fixed push rod 20 to fully contact the cigarette pack, but also shortens its length when retracting, further reducing the risk of the rotating push rod 30 overturning newly entered cigarette packs when retracting, thus ensuring the smooth progress of the cigarette pushing process.

[0035] The rotary transmission assembly 40 is used to drive the rotary push rod 30 to deflect during the resetting process of the base 10, so that the rotary push rod 30 avoids the cigarette packs that are subsequently entering the "to be pushed cigarette position" when it retracts. The rotary transmission assembly 40 includes a connecting member 41, a flipping member 42, and a blocking member 43. The connecting member 41 is fixed to the transition member 32, and the flipping member 42 is hinged to the connecting member 41, and the flipping member 42 can rotate relative to the connecting member 41 within a certain range. A second elastic reset member 44 is installed between the flipping member 42 and the connecting member 41. The blocking member 43 is a long strip structure and is fixed on the movement trajectory of the flipping member 42. When the base 10 moves toward the "to be pushed cigarette position", the flipping member 42 is blocked by the blocking member 43 and can rotate relative to the connecting member 41. During this process, the rotary push rod 30 does not deflect at all until the flipping member 42 is freed from the blocking member 43, and then the flipping member 42 is reset under the action of the second elastic reset member 44. After all the cigarette packs in the "to be pushed" position are pushed into the packaging mechanism, the base 10 begins to reset. During the reset process, the flipping component 42 is again blocked by the blocking component 43. This time, the flipping component 42 no longer rotates relative to the connecting component 41, but cooperates with the connecting component 41 to cause the rotating push rod 30 to gradually deflect, thereby avoiding the subsequent entry of cigarette packs into the "to be pushed" position. After the flipping component 42 separates from the blocking component 43, the rotating push rod 30 can reset under the action of the first elastic reset component 35, preparing for the next cigarette pack push.

[0036] In one embodiment, the base 10 has an arc-shaped groove 11 that extends through the upper and lower sides of the base 10. A sliding rod 36 is provided at the end of the sliding member 31 away from the connecting shaft 34, and the sliding rod 36 is slidably installed in the groove 11. Through the cooperation of the sliding rod 36 and the groove 11, the sliding member 31 is slidably installed on the base 10. This allows the sliding member 31 to gradually move away from the transition member 32 when the rotating push rod 30 deflects to avoid the cigarette pack, causing the telescopic member 33 to gradually approach the transition member 32.

[0037] In one embodiment, the slide rod 36 passes through the slide groove 11 and extends out of the slide groove 11 at both ends. The sliding member 31 has a U-shaped structure, with the top two sides of the U-shape of the sliding member 31 connected to the two ends of the slide rod 36, and the bottom end of the U-shape of the sliding member 31 fixed to the connecting shaft 34. The sliding member 31 is slidably mounted on the base 10 via the slide rod 36, and the U-shaped structure of the sliding member 31 facilitates connection.

[0038] In one embodiment, the side of the slider 31 is Z-shaped, with the outer side contacting the cigarette pack and serving as the cigarette-pushing part, flush with the fixed push rod 20, and the inner end connected to the slide rod 36. This design makes the shape of the slider 31 more suitable for its cigarette-pushing and sliding functions, ensuring that the two functions do not interfere with each other.

[0039] In one embodiment, the transition member 32 includes a pusher plate 321 and a hinge plate 322. The pusher plate 321 directly contacts the cigarette pack and serves as the pusher part, flush with the fixed push rod 20. The hinge plate 322 is vertically fixed to the pusher plate 321. A first pin 37 is provided at the end of the hinge plate 322 away from the pusher plate 321. The hinge plate 322 is hinged to the base 10 via the first pin 37, thereby allowing the entire rotating push rod 30 to deflect relative to the base 10. To limit the rotation range of the hinge plate 322, a first limiting plate 12 is fixed on the base 10. The first limiting plate 12 is located on the hinge portion of the hinge plate 322 on the side opposite to the slide groove 11, and one end of the first limiting plate 12 extends to the position of the hinge plate 322. With this configuration, when the three smoke-pushing parts of the rotating push rod 30 are aligned with the fixed push rod 20, the rotating push rod 30 can no longer rotate counterclockwise, thus limiting the initial position of the rotating push rod 30.

[0040] In one embodiment, the first elastic reset member 35 can be a first torsion spring, which is sleeved on the first pin 37, with one end of the first torsion spring abutting against the hinge plate 322 and the other end abutting against the base 10. This arrangement allows the rotating push rod 30 to remain in its initial position when no force other than the elastic force of the first torsion spring is applied, or to automatically reset to its initial position under the elastic force of the first torsion spring when all other external forces are absent.

[0041] In one embodiment, the lowest points of the connector 41, the flipper 42, and the blocking member 43 are all higher than the highest point of the cigarette pack, so that the rotary transmission assembly 40 does not affect the normal flow of the cigarette pack when it acts on the rotary push rod 30. To ensure that the lowest points of the connector 41, the flipper 42, and the blocking member 43 are all higher than the highest point of the cigarette pack, a mounting plate 45 is fixed to the lower end of the connector 41. The mounting plate 45 is fixed to the hinge plate 322 near the first pin 37, thereby increasing the horizontal height of the connector 41 and the flipper 42. A mounting bracket 46 is fixed to the blocking member 43, and the blocking member 43 is fixed to the base plate of the cigarette packaging machine via the mounting bracket 46, thereby increasing the horizontal height of the blocking member 43.

[0042] In one embodiment, a second pin 47 is provided at the end of the connector 41 away from the mounting plate 45. The connector 41 and the flipper 42 are hinged together by the second pin 47, thereby allowing the flipper 42 to rotate relative to the connector 41. To limit the rotation range of the flipper 42, a second limiting plate 48 is fixed to the connector 41. The second limiting plate 48 is fixed at the hinge portion of the connector 41 on the side facing the smoke pusher plate 321, and one end of the second limiting plate 48 extends to the position of the flipper 42. With this arrangement, when the flipper 42 is flipped to be flush with the connector 41, the flipper 42 can no longer rotate clockwise, thereby limiting the rotation range of the flipper 42.

[0043] In one embodiment, the second elastic reset member 44 is a second torsion spring, which is sleeved on the second pin 47. One end of the second torsion spring abuts against the connecting member 41, and the other end abuts against the flipping member 42. This arrangement ensures that the flipping member 42 remains flush with the connecting member 41 when no force other than the second torsion spring is applied, or that after the removal of other external forces, the flipping member 42 automatically resets to a position flush with the connecting member 41 under the force of the second torsion spring.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
