[0002] There are various cigarette pack packaging machines on the market. Single-layer carton types include side-opening single-layer cartons and double-opening single-layer cartons. Publication number CN115571437A describes a cigarette packaging filling line for the production of side-opening single-layer cartons, and authorization announcement number CN212710401U describes an automated filling production line for forming packaging boxes for the production of double-opening single-layer cartons. Currently, each production line is only designed for packaging one type of carton, and the specifications and dimensions of the carton cannot change. In this era of rapid product updates, this leads to increased costs for cigarette factories to upgrade their products. Summary of the Invention

[0003] To address the problems in the existing technology, the present invention provides a cigarette pack boxing line based on a multi-station linear motor, which is applicable to packaging lines for side-opening single-layer carton and double-opening single-layer carton, thereby reducing the production costs required for product replacement or upgrade.

[0004] A cigarette packing line based on a multi-station linear motor includes a linear motor 7. The linear motor 7 includes a linear guide rail 71 and several seats 72 movably mounted on the linear guide rail 71. Along the linear guide rail 71, from front to back, there are sequentially distributed a carton supply station 1b, a lid opening station 2b, a cigarette pack loading station 4b, a lid closing station 6b, and a discharge station 8b. Each station is equipped with a carton lifting support 9, which includes two synchronously lifting support platforms 91 located on the left and right sides of the linear guide rail. The seats 72 and support platforms 91 are equipped with features for positioning the cartons. The positioning device 90; a bracket 100 is provided above the linear motor 7, and the split-type opening mechanism 1 and the side-opening opening mechanism 2 are independently lifted and lowered on the bracket 100. The split-type opening mechanism 1 is used to open the lid of the split-type single-layer carton, and the side-opening opening mechanism 2 is used to open the lid of the side-opening single-layer carton. The split-type opening mechanism 1 and the side-opening opening mechanism 2 are located on the front and rear sides of the opening station 2b, respectively; a first closing mechanism 4a for closing the lid of the split-type single-layer carton is provided on the left and right sides of the closing station 6b, and a second closing mechanism 5 for closing the lid of the side-opening single-layer carton is provided at the closing station 6b.

[0005] The beneficial effects of this invention are as follows: By using a multi-station linear motor, the position of each packaging station can be flexibly adjusted to accommodate the opening and closing of split-type single-layer cartons and side-opening single-layer cartons; by adding a carton lifting seat at each station and setting positioning devices on the seat and support platform, the cartons can stop and be transferred between adjacent stations; by setting independently lifting split-type and side-opening opening mechanisms, as well as a first closing mechanism and a second closing mechanism on the packaging line, and in conjunction with multi-station linear motors, carton lifting seats, and other components, this packaging line can package different batches of split-type and side-opening single-layer cartons, thereby reducing the production costs for manufacturers.

[0019] A cigarette packing line based on a multi-station linear motor, characterized in that: Figure 1 and Figure 2As shown, the device includes a linear motor 7, which comprises a linear guide rail 71 and several seats 72 movably mounted on the linear guide rail 71. Along the linear guide rail 71, from front to back, there are sequentially distributed a carton supply station 1b, a lid opening station 2b, a cigarette pack loading station 4b, a lid closing station 6b, and a discharge station 8b. The stations are connected by transferring cartons via the seats 72, allowing for flexible adjustment of the processing time at different stations. It is required that the number of seats 72 be one less than the number of stations. Each station is equipped with a carton lifting support 9, which includes two synchronously lifting support platforms 91 located on the left and right sides of the linear guide rail, respectively. Positioning devices 90 for positioning the strip boxes are provided on both 72 and support platform 91; a bracket 100 is provided above the linear motor 7, and the split-type opening mechanism 1 and the side-opening opening mechanism 2 are independently lifted and lowered on the bracket 100. The split-type opening mechanism 1 is used to open the lid of the split-type single-layer strip box, and the side-opening opening mechanism 2 is used to open the lid of the side-opening single-layer strip box. The split-type opening mechanism 1 and the side-opening opening mechanism 2 are located on the front and rear sides of the opening station 2b, respectively; a first closing mechanism 4a for closing the lid of the split-type single-layer strip box is provided on the left and right sides of the closing station 6b, and a second closing mechanism 5 for closing the lid of the side-opening single-layer strip box is provided at the closing station 6b.

[0020] Combination Figure 3 As shown, the carton lifting support 9 also includes a transverse connecting plate 93 and a first electric telescopic cylinder 92. The transverse connecting plate 93 is horizontally positioned below the linear motor 7, and its two ends are fixedly connected to the bottom of two support platforms 91 respectively. The telescopic rod of the first electric telescopic cylinder 92 is vertically positioned and fixedly connected to the middle of the transverse connecting plate 93, thereby driving the transverse connecting plate 93 to move up and down. A support 94 is provided below the transverse connecting plate 93. The cylinder body of the first electric telescopic cylinder 92 is fixedly connected to the support 94, and the telescopic rod of the first electric telescopic cylinder 92 passes through the support 94 and is clearance-fitted with it. Vertical guide rods 96 are fixedly provided at both ends of the transverse connecting plate 93, and the guide rods 96 pass through the support 94 and are slidably fitted with it. A limit block 95 is provided on the support platform 91 located at the carton supply station 1b. The limit block 95 is located on the rear side of the top surface of the support platform 91 and is used to limit the position of the carton on the support platform 91.

[0021] like Figure 3As shown, the positioning device 90 is a suction cup structure. The suction cup structure includes a rubber pad 901 vulcanized to the top surface of the support platform 91 and the top surface of the seat 72. Negative pressure grooves 902 are distributed on the rubber pad 901. Gas channels communicating with the corresponding negative pressure grooves 902 are provided within the support platform 91 and the seat 72. The surface of the rubber pad 901 is smooth, and its surface roughness can be set to less than 1.6. After the gas channels draw in air, a negative pressure is generated within the negative pressure grooves 902, thereby adsorbing the strip box on the support platform 91 or the seat 72. Simultaneously, the surface roughness of the rubber pad 901 must be maintained to ensure the adsorption effect.

[0022] Combination Figure 4 As shown, the split-type opening mechanism 1 includes a vertically arranged first linear module 11. The body of the first linear module 11 is fixedly connected to the bracket 100. A vertical first fixing plate 12 is fixedly mounted on the slide of the first linear module 11. The surface of the first fixing plate 12 is perpendicular to the transmission direction of the linear motor 7. First servo motors 16 are fixedly connected to the left and right sides of the first fixing plate 12. The drive shaft of the first servo motor 16 is parallel to the transmission direction of the linear motor 7. A first swing arm 13 is fixedly mounted on the drive shaft of the first servo motor 16.

The device is vertically mounted, with a third suction cup 81 for adsorbing the coated paper fixedly installed at the top of the telescopic rod of the second electric telescopic cylinder 83. When the coated paper needs to be flipped out of the box, the telescopic rod of the second electric telescopic cylinder 83 extends downward and the third suction cup 81 is attracted to the set position of the coated paper. Then the telescopic rod rises and the sixth linear module 82 drives the coated paper to flip, thereby flipping the coated paper out of the box. The first suction cup 15, the second suction cup 25 and the third suction cup 81 are all flared rubber suction cups.

[0027] Combination Figure 8As shown, a film-coated paper resetting station 5b is provided between the cigarette pack insertion station 4b and the lid closing station 6b. A film-coated paper resetting mechanism 6 is fixedly installed on the bracket 100 above the film-coated paper resetting station 5b. The film-coated paper resetting mechanism 6 includes a seventh linear module 62 and a fourth servo motor 61. The seventh linear module 62 spans above the linear motor 7 and is set perpendicular to it.

[0028] like Figure 1 As shown, the first closing mechanism 4a is a guide rod for guiding the closing of the lid of the split single-layer box. This guide rod is disclosed in CN212710401U - An automated filling production line for molded packaging boxes, as... Figure 9 As shown, the second lid closing mechanism 5 includes two push rods 51 that are synchronously raised and lowered. These two push rods 51 are arranged side by side and located in front of the lid closing station 6b. These two push rods 51 are located on the left and right sides of the linear motor 7, respectively, and are used to quickly lift the lid located in front of the side-opening box and close the box after it flips over. Both push rods 51 are fixedly connected to the slide of the eighth linear module 54 and are driven by the eighth linear module 54.

[0029] A roller 53 is rotatably mounted on the top end of the top rod 51. A support plate 52 is fixed on the top of the fixed rod on the side away from the closing position 6b.

[0030] like Figure 1As shown, a labeling station 7b is provided between the capping station 6b and the discharge station 8b. A labeling machine 3a for labeling carton is provided on the bracket 100 and above the labeling station 7b. A carton supply chamber 1a is provided at the carton supply station 1b. A carton rejection device 5a is provided at the discharge station 8b.

[0031] The working process of this invention is as follows: The carton supply compartment 1a supplies the carton to the support platform 91 at the carton supply station 1b. After the support platform 91 descends, it transfers the carton to its corresponding seat 72. The seat 72 moves the carton to the opening station 2b, where the support platform 91 lifts the carton. The seat 72 then returns to its original position, and the rear seat 72 is used to transfer the carton to the cigarette pack insertion station 4b. When the carton is a split-opening single-layer carton, the split-opening mechanism 1 descends to a working position where the carton can be opened, while the side-opening mechanism 2 rises to a clearance position that does not affect the operation of the split-opening mechanism 1. When the carton is a side-opening single-layer carton, the side-opening mechanism descends to a working position where the carton can be opened. The opening mechanism 1 rises to a position that does not affect the side-opening mechanism 2. After the carton is opened, it is transferred to the cigarette pack loading station 4b. The cigarette pack pushing mechanism 4 pushes the cigarette packs on the cigarette pack conveyor belt in the cigarette pack supply line 2a onto the guide plate frame 35 of the cigarette pack loading mechanism 3. The pressing push plate 34 pushes the cigarette packs on the guide plate frame 35 into the opened carton and completes the cigarette pack loading. Then, the seat 72 in another rear position transfers the carton containing the cigarette pack to the support platform 91 at the closing station 6b. After the carton is closed, the seat 72 in the last position transfers the closed carton to the support platform 91 at the discharge station 8b. The carton rejection device 5a discharges the carton at the discharge station 8b and can pick out the products that need to be rejected.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
