Description

Technical Field

[0001] This utility model relates to the field of cigarette sorting technology, and in particular to a continuous irregular cigarette pack posture correction device. Background Technology

[0002] After being sorted on the sorting line, the cigarette cartons need to be conveyed to a coding machine for coding on the packaging. Because the dimensions and shapes of irregularly shaped cigarette cartons vary, and their positions on the conveyor belt from the sorting channel are not always uniform, barcode misalignment and omissions often occur. This causes unnecessary trouble for the next process, reducing work efficiency and quality.

[0003] To address the aforementioned issues, utility model patent CN202279273U discloses a sorting and positioning system for irregularly shaped cigarette packs. The system includes a cigarette pack conveyor belt and a coding machine installed at its output end. Two cylinders are positioned opposite each other on either side of the conveyor belt, with push plates vertically fixed to the piston rods of each cylinder above the conveyor belt. Position sensors for cigarette pack detection are installed on each cylinder. After the sorted cigarette packs are placed on the conveyor belt, regardless of whether they are irregularly shaped or conventionally packaged, as long as they are not located at the longitudinal centerline of the conveyor belt, the position sensors on the cylinders will detect them and send control signals to drive the cylinders to move the push plates to the centerline of the conveyor belt. This ensures accurate coding by the coding machine and prevents misaligned or missed coding.

[0004] However, when the above technical solution is actually used on site, the cigarette packs cannot always be perpendicular to the center line of the conveyor belt. When the cigarette packs are pushed directly by the pusher plate using two cylinders, the packaging box of the cigarette packs is easily crushed or deformed. To avoid the above situation, it is usually necessary to have a dedicated person manually rearrange the cigarette packs, which not only consumes manpower but also increases production costs. Summary of the Invention

[0005] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a continuous irregular cigarette posture correction device.

[0006] A continuous irregular-shaped cigarette posture correction and straightening device includes a conveyor belt, a posture correction mechanism, a centering and straightening mechanism, and a positioning mechanism;

[0007] The posture correction mechanism is located above the conveyor belt and can move vertically up and down in a direction perpendicular to the upper surface of the conveyor belt, so as to block the irregularly shaped cigarette strips that are inclined to the center line of the conveyor belt in the length direction and form them to be perpendicular to the center line of the conveyor belt.

[0008] There are two centering and straightening mechanisms, which are symmetrically arranged on both sides of the conveyor belt along a direction perpendicular to the center line of the conveyor belt. The two centering and straightening mechanisms move simultaneously toward the center line of the conveyor belt, which can center and correct the irregular cigarette strips on the conveyor belt. Each centering and straightening mechanism is equipped with a displacement sensor for detecting the position of the irregular cigarette strips.

[0009] The positioning mechanism is located above the conveyor belt and behind the centering and straightening mechanism. After the irregularly shaped cigarettes reach the centering and straightening mechanism, the positioning mechanism flips towards the upper surface of the conveyor belt to block and position the irregularly shaped cigarettes on the conveyor belt, so as to facilitate the centering and straightening mechanism to center and correct them.

[0010] Preferably, the centering and correction mechanism includes a telescopic cylinder and an elastic pushing component; the telescopic cylinder is perpendicular to the center line of the conveyor belt and symmetrically arranged on both sides of the conveyor belt, with the extended end of the telescopic cylinder facing the center line of the conveyor belt, and the elastic pushing component is arranged at the extended end of the telescopic cylinder, and the elastic pushing component does not contact the conveyor belt.

[0011] Preferably, the elastic pushing assembly includes an elastic buffer section and a pushing plate; one end of the elastic buffer section is connected to the extended end of the telescopic cylinder, and the other end of the elastic buffer section is fixed to the pushing plate.

[0012] Preferably, the elastic buffer includes a sleeve and a guide rod; one end of the sleeve is connected to the extended end of the telescopic cylinder, and the inside of the sleeve is provided with a spring that can extend and retract along the sleeve axis; one end of the guide rod can be inserted into the sleeve and fixed to the spring, and the other end of the guide rod is fixed to the push plate; the end of the guide rod is provided with a pressure plate for connecting the spring, and the pressure plate can slide along the inside of the sleeve.

[0013] Preferably, the outer wall of the sleeve is provided with a guide groove arranged along the axis of the sleeve, and the edge of the pressure plate is provided with a protrusion that can pass through the guide groove and slide along the guide groove.

[0014] Preferably, the attitude correction mechanism includes a gantry frame, a telescopic component, and a blocking part; the gantry frame spans across the conveyor belt, the telescopic component is longitudinally arranged on the gantry frame, the extended end of the telescopic component faces the conveyor belt, and the blocking part is arranged at the extended end of the telescopic component.

[0015] Preferably, the blocking part includes a baffle and a flexible anti-scratch component; the baffle is connected to the extended end of the telescopic component, and the flexible anti-scratch component is detachably connected to the bottom of the baffle.

[0016] Preferably, the bottom of the baffle is provided with a T-slot, the upper end of the flexible anti-scratch component is provided with an I-shaped connector that can be inserted into the T-slot, and the lower part of the baffle is provided with a pressure sensor.

[0017] Preferably, the positioning mechanism includes a support frame spanning above the conveyor belt, a positioning plate, and a telescopic push rod; the positioning plate is rotatably mounted on the support frame, one end of the telescopic push rod is hinged to the gantry frame, and the other end of the telescopic push rod is hinged to the upper end of the positioning plate. When the telescopic push rod extends forward, it can cause the positioning plate to flip upward along the support frame, and when the telescopic push rod retracts backward, it can cause the positioning plate to flip downward along the support frame, and make the positioning plate perpendicular to the upper surface of the conveyor belt.

[0018] Preferably, the support frame is provided with a positioning block that allows the positioning plate to remain vertical after being flipped downwards.

[0019] Compared with existing technologies, the continuous irregular cigarette pack posture correction and alignment device provided by this utility model, through the up and down movement of the posture correction mechanism, can not only make the irregular cigarette packs tilted on the conveyor belt perpendicular to the center line of the conveyor belt after being blocked, but also, after the irregular cigarette packs reach the centering and alignment mechanism, the positioning mechanism flips towards the upper surface of the conveyor belt to block and position the irregular cigarette packs on the conveyor belt. The two centering and alignment mechanisms move simultaneously towards the center line of the conveyor belt, which can center and correct the irregular cigarette packs on the conveyor belt, so that the irregular cigarette packs are in the middle position of the conveyor belt. After the centering work is completed, the positioning mechanism flips upward, and the two centering and alignment mechanisms retract to the initial state, releasing the corrected and aligned irregular cigarette packs. In the whole process, the posture of the irregular cigarette packs can be continuously corrected and aligned, without the need for personnel to manually correct the posture of the irregular cigarette packs. It can also effectively avoid crushing and damaging the packaging boxes of irregular cigarette packs, which not only saves manpower but also improves production efficiency.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please refer to Figures 1 to 4This utility model provides a continuous irregular cigarette pack posture correction and adjustment device, including a conveyor belt 01, a posture correction mechanism 03, a centering and straightening mechanism 02, and a positioning mechanism 04. The posture correction mechanism 03 is disposed above the conveyor belt 01 and can move vertically up and down in a direction perpendicular to the upper surface of the conveyor belt 01, so as to block irregular cigarette packs that are inclined to the centerline of the conveyor belt 01 in the length direction and form them perpendicular to the centerline of the conveyor belt 01. There are two centering and straightening mechanisms 02, which are symmetrically arranged on both sides of the conveyor belt 01 in a direction perpendicular to the centerline of the conveyor belt 01. The two centering and straightening mechanisms 02 move simultaneously toward the centerline of the conveyor belt 01, which can center and correct the irregular cigarette packs on the conveyor belt 01. Each centering and straightening mechanism 02 is equipped with a displacement sensor for detecting the position of the irregular cigarette packs. The positioning mechanism 04 is located above the conveyor belt 01 and behind the centering and straightening mechanism 02. After the irregularly shaped cigarettes reach the centering and straightening mechanism 02, the positioning mechanism 04 flips towards the upper surface of the conveyor belt 01 to block and position the irregularly shaped cigarettes on the conveyor belt 01, so that the centering and straightening mechanism 02 can center and correct them.

[0031] In use, the up-and-down movement of the posture correction mechanism 03 can both prevent the irregularly shaped cigarette packs tilted on the conveyor belt 01 from being blocked and made perpendicular to the centerline of the conveyor belt 01, and after the irregularly shaped cigarette packs reach the centering and straightening mechanism 02, the positioning mechanism 04 flips towards the upper surface of the conveyor belt 01 to block and position the irregularly shaped cigarette packs on the conveyor belt 01. The two centering and straightening mechanisms 02 move simultaneously towards the centerline of the conveyor belt 01 to center and correct the irregularly shaped cigarette packs on the conveyor belt 01, so that the irregularly shaped cigarette packs are in the middle position of the conveyor belt 01. After the centering work is completed, the positioning mechanism 04 flips upward and the two centering and straightening mechanisms 02 retract to the initial state, releasing the corrected and centered irregularly shaped cigarette packs. Throughout the process, no personnel are required to manually correct the posture of the irregularly shaped cigarette packs, and the packaging boxes of the irregularly shaped cigarette packs can be squeezed and damaged, which not only saves manpower but also improves production efficiency.

[0032] In one embodiment, the centering and straightening mechanism 02 includes a telescopic cylinder 21 and an elastic pushing component 22. The telescopic cylinder 21 is perpendicular to the centerline of the conveyor belt 01 and symmetrically arranged on both sides of the conveyor belt 01. The extended end of the telescopic cylinder 21 faces the centerline of the conveyor belt 01. The elastic pushing component 22 is arranged at the extended end of the telescopic cylinder 21 and does not contact the conveyor belt 01.

[0033] Specifically, the elastic pushing assembly 22 includes an elastic buffer part 221 and a pushing plate 222; one end of the elastic buffer part 221 is connected to the extended end of the telescopic cylinder 21, and the other end of the elastic buffer part 221 is fixed to the pushing plate 222. The elastic buffer part 221 can form a certain buffering force after the pushing plate 222 contacts the irregularly shaped cigarette pack, reducing the squeezing of the irregularly shaped cigarette pack box and preventing the irregularly shaped cigarette pack box from being squeezed and damaged.

[0034] Specifically, the elastic buffer part 221 includes a sleeve 2211 and a guide rod 2212; one end of the sleeve 2211 is connected to the extended end of the telescopic cylinder 21, and the inside of the sleeve 2211 is provided with a spring 2213 that can extend and retract along the axis of the sleeve 2211; one end of the guide rod 2212 can be inserted into the sleeve 2211 and fixed to the spring 2213, and the other end of the guide rod 2212 is fixed to the push plate 222.

[0035] The guide rod 2212 has a pressure plate 2214 at its end for connecting a spring 2213. The pressure plate 2214 can slide along the inside of the sleeve 2211. A guide groove 2215 is provided on the outer wall of the sleeve 2211, arranged along the axis of the sleeve 2211. The edge of the pressure plate 2214 has a protrusion 2216 that can pass through and slide along the guide groove 2215. The protrusion 2216 not only provides guidance but also restricts the rotation of the guide rod 2212 in the circumferential direction.

[0036] In one embodiment, the attitude correction mechanism 03 includes a gantry frame 31, a telescopic component 32, and a blocking part 33; the gantry frame 31 spans across the conveyor belt 01, the telescopic component 32 is longitudinally disposed on the gantry frame 31, the extended end of the telescopic component 32 faces the conveyor belt 01, and the blocking part 33 is disposed at the extended end of the telescopic component 32.

[0037] Specifically, the blocking part 33 includes a baffle 331 and a flexible anti-scratch component 332; the baffle 331 is connected to the extended end of the telescopic component 32, and the flexible anti-scratch component 332 is detachably connected to the bottom of the baffle 331. For example, bolt connection, slot connection, pin connection, threaded connection and other connection methods can be used.

[0038] Specifically, a T-slot 333 is provided at the bottom of the baffle 331, and an I-beam connector 334 is provided at the upper end of the flexible anti-scratch component 332, which can be inserted into the T-slot 333, so that the flexible anti-scratch component 332 can be connected to the baffle 331, and it is also convenient to replace when needed. Among them, the flexible anti-scratch component 332 is a brush.

[0039] Of course, a pressure sensor can also be installed at the lower part of the baffle 331. After the irregularly shaped cigarette comes into contact with the baffle 331, the pressure sensor can detect the contact between the irregularly shaped cigarette and the baffle 331, thus ensuring that the irregularly shaped cigarette is perpendicular to the center line of the conveyor belt 01 after being blocked by the baffle 331.

[0040] In one embodiment, the positioning mechanism 04 includes a support frame 41 spanning above the conveyor belt 01, and positioning plates 42 and 43. Positioning plate 42 is rotatably mounted on the support frame 41. One end of 43 is hinged to a portal frame, and the other end of 43 is hinged to the upper end of positioning plate 42. When 43 extends forward, it can cause positioning plate 42 to flip upward along the support frame 41. When 43 retracts backward, it can cause positioning plate 42 to flip downward along the support frame 41, making positioning plate 42 perpendicular to the upper surface of the conveyor belt 01. When positioning plate 42 flips downward and is perpendicular to the upper surface of the conveyor belt 01, it can block and position the irregularly shaped cigarette packs. At this time, telescopic cylinder 21 will drive elastic pushing component 22 to move towards the centerline of the conveyor belt 01, using elastic pushing component 22 to center and correct the irregularly shaped cigarette packs. After centering and correction, positioning plate 42 flips upward, and telescopic cylinder 21 retracts to its initial position. Elastic pushing component 22 disengages from the irregularly shaped cigarette packs, and the irregularly shaped cigarette packs can continue to be conveyed forward by the conveyor belt 01.

[0041] The support frame 41 is provided with a positioning block that allows the positioning plate 42 to remain vertical after being flipped downwards.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
