Description

Technical Field

[0001] The utility model relates to a cigarette pushing and packing system, in particular to a two-way cigarette pushing and packing system, belonging to a packing device in a cigarette stacking system. Background Art

[0002] At present, the specifications and sales of special-shaped cigarettes are increasing, which puts higher requirements on the existing commercial cigarette sorting equipment and logistics management. There are more than 300 tobacco logistics distribution centers under the jurisdiction of 33 provincial companies across the country. The equipment varies greatly, and the overall technical level of special-shaped cigarette sorting automation is still relatively low. The stacking mode can be roughly divided into three forms: 1. Manual stacking mode; 2. Semi-automatic stacking mode; 3. Automatic stacking mode.

[0003] The multi-station special-shaped cigarette stacking and packaging system is an indispensable and important part of the special-shaped cigarette sorting line in cigarette logistics. It can provide a strong technical guarantee for improving the production efficiency of cigarette logistics and improve the working efficiency and adaptability of the special-shaped cigarette sorting line.

[0004] Take the Xuchang Tobacco Logistics and Distribution Center in Henan Province as an example: Xuchang Tobacco Logistics and Distribution Center has a new special-shaped cigarette sorting line. The stacking of special-shaped cigarettes adopts the automatic stacking mode of "two sets of cigarette stacking devices + 1 parallel manipulator". The cigarette stacking device pushes the cigarettes from the end of the cigarette (1 to 5 cigarettes each time), which is suitable for the same-layer stacking of cigarettes of different lengths. Special-shaped cigarettes are grabbed and stacked by parallel manipulators. The grabbing speed of the manipulator is 1.6 seconds / time, which can realize single grabbing and double grabbing functions. With the increase of special-shaped cigarette specifications, the number of special-shaped cigarette specifications in the cigarette logistics and distribution center of Xuchang Tobacco Company has exceeded 100, and the daily sorting volume of special-shaped cigarettes has surged to about 30,000. The daily sorting volume of special-shaped cigarettes in the peak season of Yuanchun has reached about 100,000. At this time, the speed of the manipulator has reached the upper limit. The high-loaded manipulator has high requirements for cigarette posture, high maintenance difficulty, long working hours, increased number of employees, and poor adaptability. It is urgent to improve the sorting efficiency. Utility Model Content

[0005] The utility model aims to provide a two-way cigarette pushing and packaging system to solve the problem of low efficiency in the prior art when cigarette brands are stacked.

[0006] In order to solve the above problems, the two-way cigarette pushing and packaging system involved in the utility model adopts the following technical solutions: a two-way cigarette pushing and packaging system, including a frame, a working platform on the frame, shift stations are arranged on the left and right sides of the working platform, the front side of the working platform is connected to the smoke feeding and conveying device, and a limit frame is arranged on the frame at the rear side of the working platform during operation, and the limit frame can slide in the front and rear directions of the working platform, and a smoke pressing member for pressing the smoke downward from the top is slidably arranged on the front side of the working platform on the frame, and a cigarette removing plate is arranged on the working platform to slide between the left and right sides of the working platform.

[0007] The limiting frame is provided with a capacitive sensor.

[0008] Baffles are arranged on the left and right sides of the smoke feeding and conveying device.

[0009] The cigarette removing plate is a strip-shaped body, and the cigarette removing plate 2 is driven to slide by a rodless cylinder.

[0010] The limit frame is located above the cigarette removing plate, and the rodless cylinder driving slide is located at the rear side of the working platform.

[0011] The limiting frame is slidably assembled with the frame through the upper two sides.

[0012] The limit frame is fixed to the limit frame through the front parts of two slide rods, the front parts of the two slide rods are fixed to the limit frame, the two slide rods are slidably assembled with the frame, and the two slide rods are driven by an electric cylinder.

[0026] In order to make the technical purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0027] The specific embodiment of the two-way cigarette pushing and packaging system involved in the utility model is as follows: Figure 1-Figure 6In the embodiment, the frame 1 has a working platform 2, which is a square platform with four sides, namely the front side, the back side, the left side and the right side. These directions can be selected arbitrarily before definition and determined after definition. Shifting stations 3 are arranged on the left and right sides of the working platform 2. The so-called shifting station includes a cigarette pushing platform 4. There is a lifting platform in front of the cigarette pushing platform. After the cigarettes reach the cigarette pushing platform, they are pushed into the lifting platform by the cigarette pushing platform to prepare for subsequent stacking. The shifting station is a prior art. The front side of the working platform 2 is connected to the cigarette feeding and conveying device, which is a conveyor belt device 5. A limit frame 6 is also slidably arranged on the frame 1. The limit frame 6 can slide in the front and rear directions of the working platform 2. The limit frame 6 is slidably assembled with the frame 1 through two slide bars 7. The two slide bars 7 are respectively fixed to the upper two sides of the limit frame 6. The slide bars 7 are slidably assembled with the frame 1. The rear ends of the two slide bars 7 are fixed to the push plate 8. The push plate 8 is connected to the electric cylinder 9 and driven by the electric cylinder 9. When working, the limit frame 6 is at the rear side of the working platform 2. A smoke pressing part 10 is slidably arranged on the frame 1. The smoke pressing part 10 is driven up and down by the pneumatic cylinder 11 and is at the front side of the working platform 2. A cigarette plucking plate 12 is slidably arranged on the working platform 2, and the cigarette plucking plate 12 slides between the left and right sides of the working platform 2. The cigarette plucking plate 12 is a strip-shaped body, and is driven to slide by a rodless cylinder 13, and the rodless cylinder 13 is located on the side of the rear side of the working platform 2. In order to avoid motion interference, the limit frame 6 is located above the cigarette plucking plate 12. Both the electric cylinder and the rodless cylinder are commercially available.

[0028] The limiting frame in this embodiment is provided with a capacitive sensor, but it may not be provided in other embodiments.

[0029] In this embodiment, baffles (not shown in the figure) are arranged on the left and right sides of the smoke feeding and conveying device, which may not be arranged in other embodiments.

[0030] In this embodiment, the cigarette prying plate is a strip-shaped body, and the cigarette prying plate is driven to slide by a rodless cylinder. In other embodiments, the cigarette prying plate may also be in other shapes, and may also be driven by other linear drive structures.

[0031] In this embodiment, the limit frame is located above the cigarette removing plate, and the rodless cylinder driving the slide is located at the rear side of the working platform. In other embodiments, the rodless cylinder can also be arranged at other positions, for example, below the working platform.

[0032] The limit frame in this embodiment is fixed to the limit frame through the front parts of the two slide bars, and the two slide bars are slidably assembled with the frame. In other embodiments, other structures can also be slidably assembled with the frame, and the driving power can also be other linear driving structures.

[0033] The smoke pressing part in this embodiment is slidably assembled on the frame, and is driven by a pneumatic cylinder to move up and down. In other embodiments, the smoke pressing part can also be assembled with the frame by other assembly forms, as long as it can be pressed from top to bottom, such as moving horizontally first and then moving up and down.

[0034] The smoke feeding and conveying device of the utility model is a conveyor belt device, and may also be other forms of conveying devices.

[0035] During operation, in order to ensure the accuracy of the data of each order and avoid order confusion, the electric cylinder controls the position of the limit frame according to the width of the cigarettes in the order to ensure the accuracy of the quantity and specifications each time; a capacitive sensor is installed in the middle position of the limit frame to sense the arrival of the cigarettes; after the limit frame senses the signal that the cigarettes are in place, the cylinder of the pressing mechanism extends to press the cigarettes that do not need to be removed, providing a relatively closed space for the cigarettes in place; a channel is formed between the pressing mechanism and the limit bracket, and the rodless cylinder drives the cigarette removing plate to move left and right, so that 4 cigarettes can be moved together at a time and enter the cigarette pushing platform; the cigarette pushing platform then pushes the stack of cigarettes into the lifting platform to prepare for subsequent stacking.

[0036] The mechanical performance and mechanical hard limit of the device are improved, which can reduce the complexity of the electrical program and the probability of data errors and signal errors. The design of the device here reduces the use of detection elements by more than 5 compared with the manipulator device. The electric cylinder only needs to determine the origin, the rodless cylinder reciprocates at the limit position, and the limit bracket is installed with a capacitive sensing element. The downward pressure cylinder is not installed in place for detection, and the logical detection of the length of the cigarette is cancelled, which greatly optimizes the difficulty of program writing. The entire device is simple and easy to repair, reducing the pressure of subsequent maintenance.

[0037] Based on the original equipment, the "left and right double-pick" structure is used. The cigarette picking speed is 4 seconds / time, and 1 to 5 cigarettes are picked each time. The equipment operation efficiency is improved, the safety protection of cigarette stacks is strengthened, the cigarette volume per pack is increased, and the production efficiency of the overall sorting line is improved.

[0038] The original parallel manipulator is removed, and a new "left and right separation" horizontal shifting mechanism is designed. According to the width size model of a single cigarette, the positioning size of a single cigarette is designed. When in use, a servo motor can be used to control the moving distance of the electric cylinder, and the capacitance sensor on the limit frame can be used to judge the cigarette carton's position. A pressing mechanism is designed, and the cigarette pressing piece compacts the first cigarette of the order to form a closed space for the cigarettes to be shifted. The rodless cylinder design is used as the power to drive the cigarette shifting rod, separate the cigarettes left and right, and shift them into the shifting station. The cigarette pushing cylinder pushes the stacked cigarettes into the lifting platform station, and the lifting platform performs subsequent actions such as stacking or individual stacking.

[0039] The cigarette pulling section is equipped with a servo smoke blocking component, i.e. a limit frame structure, which can locate the total number of single-layer stacked cigarettes according to the number of single-layer cigarette strips to prevent false alarms or mis-pulling of cigarettes due to slanted cigarettes.

[0040] A cigarette pressing component, namely, a cigarette pressing piece, is added to the front end of the cigarette pulling section. When working, multi-stage conveying is adopted, that is, the products are segmented on the conveying device, and not all of them are squeezed together. There is a gap between one part and another part, which effectively reduces the squeezing force of the cigarette strips in the cigarette pulling section, ensures the cigarette posture and increases the stability of pushing and stacking cigarettes.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
