Description

Technical Field

[0001] This utility model relates to a dual-station replenishment cart, belonging to the technical field of replenishment carts. Background Technology

[0002] After the cigarette cartons are pushed from the cigarette boxes at different workstations to the cigarette receiving and walking equipment, they need to be sorted to separate the cartons into individual cartons. However, the cigarette receiving and walking equipment is a transitional device, usually used to push in single cartons of cigarettes. The cigarette receiving and walking equipment is equipped with a belt that runs to the right. After being blocked on the right, a single-row push mechanism is used to push the stacked single-row cigarette cartons out of the cigarette receiving and walking equipment. Then, the single-row is sorted into individual cartons. This structure is inefficient. If a double-row system is used, the push process may be blocked due to misalignment of the two rows of cigarettes, which can easily damage the cigarette cartons. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dual-station replenishment trolley that can realize the simultaneous operation of two cigarette packs, which is highly efficient and less likely to damage the cigarette packs.

[0004] The technical solution adopted by this utility model is as follows: a dual-station replenishment trolley, including a frame, a cigarette receiving belt conveyor, a cigarette feeding mechanism, and a cigarette pushing mechanism. The cigarette receiving belt conveyor is installed longitudinally on the frame and near the bottom. A smoke baffle is provided on the rear side of the frame and located at the rear end of the cigarette receiving belt conveyor. The cigarette feeding mechanism is installed on the left side of the cigarette receiving belt conveyor and can push the cigarette packs to the cigarette pushing mechanism on the right side. The cigarette pushing mechanism is installed on the right side of the cigarette receiving belt conveyor and can push a column of cigarette packs out from the smoke outlet provided on the smoke baffle. The longitudinal space of the cigarette receiving belt conveyor can accommodate two cigarette packs.

[0005] Furthermore, the aforementioned cigarette feeding mechanism includes a cigarette feeding plate, a slide block, guide rods, a lead screw pair, and a cigarette feeding motor. The length of the cigarette feeding plate is greater than 1.5 times the length of a single cigarette but less than the length of two cigarettes. The top of the cigarette feeding plate is fixedly connected to the bottom of the slide block via an L-shaped plate, and the distance between the cigarette feeding plate and the upper surface of the cigarette receiving conveyor belt is less than the thickness of a single cigarette. The slide block is slidably connected to two guide rods, and the two ends of the two guide rods are connected to the top of the frame frame via fixed seats. The lead screw pair is fixedly connected to the middle of the slide block, and the two ends of the lead screw pair are rotatably connected to the fixed seats, with one end extending out of the fixed seats and connected to the cigarette feeding motor via a synchronous belt mechanism.

[0006] Furthermore, the aforementioned cigarette pushing mechanism includes a cigarette pushing plate, a support plate, a double-chain drive mechanism, and a cigarette bar limiting plate. The links of the double-chain drive mechanism are vertically connected to multiple cigarette bar limiting plates. A cigarette pushing plate is arranged on one side of each of the multiple cigarette bar limiting plates. The cigarette pushing plate is fixedly connected to two links of the double-chain drive mechanism through two support plates. The gap between the bottom of the cigarette pushing plate and the cigarette bar limiting plate and the belt of the cigarette receiving conveyor is less than the thickness of a cigarette bar, and the upper end is higher than the height of the cigarette bar being pushed in. The double-chain drive mechanism is mounted on the frame frame through a chain frame. The two chains are distributed vertically and move horizontally in a circumferential direction. The length of the double-chain drive mechanism is sufficient to push a single row of cigarette bars out of the cigarette outlet.

[0007] Furthermore, the upper and lower ends of each of the above-mentioned cigarette bar limiting plates are respectively connected to the outer side of the vertical plate of the inverted L-shaped chain link plate set on the lower side of the chain through pads. The inner side of the vertical plate of the L-shaped chain link plate is rotatably connected to two rollers, which can be placed on the track. Each chain has two tracks, and the two tracks are fixedly connected to both sides of the chain frame through two inverted L-shaped mounting brackets and keep them on the same horizontal plane.

[0008] Furthermore, the aforementioned dual-chain drive mechanism is equipped with two sets of cigarette pusher plates and cigarette limit plates.

[0009] Furthermore, a smoke-pressing plate is connected to the upper side of the aforementioned chain frame via a mounting frame. The smoke-pressing plate is a horizontal L-section strip structure, with the end facing the smoke-feeding mechanism bent upwards into an inclined section.

[0010] Furthermore, the aforementioned mounting frame is a frame structure with a rectangular cross-section formed by bending a long strip of board four times and then movably overlapping its two free ends, with the two free ends of the mounting frame located on the lower side.

[0011] Furthermore, a power-driven walking assembly is provided at the bottom of the aforementioned frame frame. The power-driven walking assembly includes walking wheels, a walking drive motor, and limit wheels. The walking wheels are arranged in two rows, with two wheels in each row. They are rotatably connected to bearing seats on the base frame via walking rotating shafts. The base frame is fixedly connected to the bottom of the frame frame. One of the walking rotating shafts is connected to the output end of the gearbox. The gearbox is fixedly connected to the base frame. The walking drive motor is installed at the input end of the gearbox and can drive the gearbox to operate. The two walking wheels on the side that pushes out the cigarette pack are provided with two sets of limit wheels symmetrical to the walking wheels, with two limit wheels in each set.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model automatically aligns two cartons of cigarettes longitudinally after they are received by the longitudinal cigarette receiving conveyor belt and blocked by the smoke baffle on the rear side. Then, the cigarette feeding mechanism on the left side pushes the two cartons of cigarettes towards the limiting smoke baffle on the right side, realizing the alignment of the two cartons of cigarettes in two directions. Finally, the cigarette pushing mechanism at the limiting smoke baffle pushes the cartons of cigarettes out from the rear side, realizing the smooth push out of a single row of cigarettes from the two cartons of cigarettes, avoiding damage to the cigarettes, improving the safety of cigarette transfer and sorting, and enabling simultaneous pushing and sorting of two cartons of cigarettes, greatly improving efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figure 1-10As shown, a dual-station replenishment trolley includes a frame 1, a cigarette receiving conveyor belt 2, a cigarette feeding mechanism 3, and a cigarette pushing mechanism 4. The cigarette receiving conveyor belt 2 is longitudinally mounted on the frame 1 and installed near the bottom. A smoke baffle 5 is provided on the rear side of the frame 1 and located at the rear end of the cigarette receiving conveyor belt 2. The cigarette feeding mechanism 3 is installed on the left side of the cigarette receiving conveyor belt 2 and can push the cigarettes 6 to the cigarette pushing mechanism 4 on the right side. The cigarette pushing mechanism 4 is installed on the right side of the cigarette receiving conveyor belt 2 and can push a row of cigarettes 6 out of the smoke outlet 7 provided on the smoke baffle 5. The cigarette receiving conveyor 2 is longitudinally empty. The compartment can accommodate two cartons of cigarettes. After the two cartons are received by the longitudinal cigarette receiving conveyor belt, they are automatically aligned longitudinally by the smoke baffle at the rear. Then, the cigarette feeding mechanism on the left pushes the two cartons of cigarettes towards the limiting smoke baffle on the right, achieving alignment of the two cartons of cigarettes in two directions. Finally, the cigarette pushing mechanism at the limiting smoke baffle pushes the cartons of cigarettes out from the rear, achieving smooth exit of a single row of cigarettes from the two cartons, avoiding damage to the cartons, improving the safety of cigarette transfer and sorting, and enabling simultaneous pushing and sorting of two cartons of cigarettes, greatly improving efficiency.

[0025] The frame 1 includes a top frame 101, a bottom frame 102, and columns 103 fixedly connected between the four corners of the top frame 101 and the bottom frame 102. A partition wall 104 is set near the left side of the frame 1 to facilitate the placement of electrical equipment outside the partition wall. Two auxiliary reinforcing columns 105 are set at the feed inlet of the smoke conveyor belt 2.

[0026] To ensure stable cigarette feeding, the cigarette feeding mechanism 3 includes a cigarette feeding plate 301, a slide 302, a guide rod 303, a lead screw pair 304, and a cigarette feeding motor 305. The length of the cigarette feeding plate 301 is greater than 1.5 times the length of a single cigarette but less than the length of two cigarettes. It extends to the auxiliary reinforcing column 105 near the feed inlet via a connecting extension guide plate 310. The top of the cigarette feeding plate 301 is fixed to the bottom of the slide 302 by two L-shaped plates 306 clamping it back-to-back. The distance between the cigarette feeding plate 301 and the upper surface of the cigarette receiving conveyor belt 2 is less than the thickness of a single cigarette. The slide 302 is connected to the slide 302 by two L-shaped plates 306 clamping it back-to-back. A linear bearing 309 is slidably connected to two guide rods 303. The two ends of the two guide rods 303 are connected to the top of the frame 1 through a fixed seat 307. The middle of the slide 302 is fixedly connected to the nut of the lead screw pair 304. The two ends of the lead screw pair 304 are rotatably connected to the fixed seat 307, and one end extends out of the fixed seat and is connected to the smoke delivery motor 305 through the synchronous belt mechanism 308. The lead screw and lead screw pair drive the smoke delivery plate to move directionally along the two pairs of linear guides, improving the driving stability and avoiding the problem of unstable pushing due to weak rigidity caused by the cantilever of the smoke delivery plate. The top arrangement will not interfere with other equipment and is compact.

[0027] To stably push out a single row of double-row cigarette packs, the cigarette pushing mechanism 4 includes a cigarette pushing plate 401, a support plate 402, a double-chain drive mechanism 403, and cigarette pack limiting plates 404. Multiple cigarette pack limiting plates 404 are vertically connected to the chain links of the double-chain drive mechanism 403. A cigarette pushing plate 401 is arranged on one side of each of the multiple cigarette pack limiting plates 404. The cigarette pushing plate 401 is fixedly connected to two chain links of the double-chain drive mechanism 403 via two support plates 402. The gap between the bottom of the cigarette pushing plate 401 and the cigarette pack limiting plate 404 and the belt of the cigarette receiving conveyor 2 is small. The thickness of a cigarette bar is such that the upper end is higher than the height of the cigarette bar being pushed in. The double-chain drive mechanism 403 is mounted on the frame frame 1 via the chain frame 405. The two chains are distributed vertically and move horizontally in a circumferential direction. The length of the double-chain drive mechanism 403 is sufficient to push a single row of cigarette bars 6 out of the cigarette outlet 7. The double-chain mechanism is connected to the cigarette pusher plate, which can achieve stable pushing of the cigarette pusher plate. Moreover, the double-chain drive mechanism 403 is equipped with two sets of cigarette pusher plates 401 and cigarette bar limit plates 404, which are convenient for repeated use and avoid the interruption of the cigarette delivery mechanism caused by discontinuity, thus avoiding low efficiency.

[0028] To prevent the cigarette bar limiting plates from interfering with the chain, each cigarette bar limiting plate 404 is connected at its upper and lower ends to the outer side of the vertical plate of the inverted L-shaped chain link plate 407 set on the lower side of the chain via pads 406. Two rollers 408 are rotatably connected to the inner side of the vertical plate of the L-shaped chain link plate 407. The two rollers 408 can rest on the track 409. Two tracks 409 are set for each chain. The two tracks 409 are fixedly connected to both sides of the chain frame 405 via two inverted L-shaped mounting brackets 410 and keep them on the same horizontal plane. By setting pads to connect to the L-shaped chain link plates, interference with chain rotation can be avoided. Moreover, the roller support can support the installed chain plate and push the cigarette pusher plate smoothly forward during the pushing process, improving the stability of pushing cigarettes and preventing damage caused by long-term additional stress at the chain connection to the cigarette pusher plate.

[0029] In order to push out the cigarette packs smoothly, a cigarette pressing plate 412 is connected to the upper side of the chain frame 405 via a mounting frame 411. The cigarette pressing plate 412 is a horizontal L-section strip structure, with the end facing the cigarette feeding mechanism 3 bent upward into an inclined part, which can place all the fed cigarette packs under the cigarette pressing plate. During the cigarette pushing process, it is more stable and reliable, and the cigarette packs will not be lifted up due to excessive speed.

[0030] For ease of installation, the mounting frame 411 is a rectangular frame structure formed by bending a long strip of board four times and then movably overlapping its two free ends. The two free ends of the mounting frame 411 are located on the lower side. This frame structure is lightweight, making it easy to install the smoke-pressing plate. Moreover, the movable overlap of the free ends also provides a certain degree of elasticity, which can provide a certain degree of pushing and protection when the smoke-feeding mechanism is inserted.

[0031] To facilitate rapid docking of the cigarette-pushing mechanism at different locations, a power-driven walking assembly 8 is installed at the bottom of the frame 1. This assembly enables rapid positional movement. The power-driven walking assembly 8 includes walking wheels 801, a walking drive motor 802, and limit wheels 803. The walking wheels 801 are arranged in two rows, with two wheels in each row. They are rotatably connected to bearing seats 806 on the base frame 805 via a walking rotation shaft 804. The base frame 805 is fixedly connected to the bottom of the frame 1. One of the walking rotation shafts 804 is connected to the output end of a transmission 807, which is fixedly connected to the base frame 805. The walking drive motor 802 is installed at the input end of the transmission 807 and can drive the transmission 807 to move, ensuring stable movement. To achieve directional movement, two sets of limit wheels 803 are symmetrically arranged on the two walking wheels 801 on the side where the cigarette pack is pushed out. Each set of limit wheels 803 consists of two wheels.

[0032] In operation, the cigarette receiving conveyor belt transports the first pack of cigarettes forward to the smoke baffle. The second pack of cigarettes is then received and placed against the front of the first pack. The cigarette feeding mechanism then pushes both packs of cigarettes to the right and against the limiting smoke baffle. By controlling the cigarette pushing mechanism, the stacked cigarettes can be pushed out of the smoke outlet on the rear side. After being pushed out, the cigarette feeding mechanism continues to move to the right for the width of one pack of cigarettes. At this point, the second set of cigarette pushing mechanisms is in place, and the next round of pushing continues until all two packs of cigarettes have been pushed out. Then, the cigarette feeding mechanism is controlled to return to the starting position for the next round of receiving.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
