Description

Technical Field

[0001] The invention belongs to the field of tobacco packaging machinery, and in particular relates to a filling device and a filling method for a double-opening strip box for cigarettes. Background Art

[0002] Cigarette cartons, which are often given as gifts, have three major technical features: the use of white paper, pre-gluing and forming, and structural diversity. Among them, the cigarette split-leaf cartons are a more representative type of this type of cartons. They are beautiful and well-liked by consumers, and have a broad market prospect. The cigarette split-leaf cartons use relatively set L-shaped left and right lids to achieve opening and closing.

[0003] However, due to the special structure and style of the double-leaf cigarette cartons, it is impossible to use existing forming equipment to achieve large-scale and high-efficiency industrial filling operations of cigarette packs.

[0004] Currently, the opening, filling, closing and packaging of cigarette cartons can only be completed manually. This method is very inefficient, costly, and has large quality fluctuations and is difficult to control.

[0005] If we want to solve the problems of low efficiency, difficult quality control, and complex production organization caused by manual filling of cigarette packs, we can only develop automatic cigarette packing equipment for double-leaf cigarette cartons as soon as possible for the application of double-leaf cigarette cartons.

[0006] In addition, the existing cigarette split-type carton boxes are pre-installed with drying bags to ensure the dryness of the boxes. In the automated operation, if you want to take out the drying bags, because of their small size, you should first use a detection and positioning mechanism to locate the position of the drying bags in the box, and then use expensive equipment such as a manipulator to take out the drying bags. This operation process is complicated, the equipment cost is high, and it is not conducive to actual production. Summary of the invention

[0007] The purpose of the present invention is to provide an easy-to-control, highly automated double-leaf cigarette box packaging equipment and a process method to address the defects of the prior art, namely the problems existing in manual production, so as to solve the current problems of low manual packaging efficiency of double-leaf cigarette boxes, uncontrollable product quality, and difficult personnel management.

The upper mold box of the synchronous belt can be opened to move out the strip box.

[0017] The upper synchronous belt part and the lower synchronous belt part mentioned above are only relative expressions. During the operation of the synchronous belt, the upper part is the upper synchronous belt part, and the lower part is the lower synchronous belt part.

[0018] The operating range of the first mold box release mechanism corresponds to the upstream of the lower synchronous belt part of the synchronous belt to ensure that the strip box is first accommodated in the mold box and then transported to the lower synchronous belt part of the synchronous belt, so that the strip box is inverted and the box cover is opened to fall out of the drying bag.

[0026] The small shaft I23 passes through the rocker arm I, the left fixed bracket, the rocker arm I, the rocker arm II, the middle fixed bracket, and the rocker arm II in sequence from front to back;

[0027] The left support 1 is connected to the rocker 1 and the left side plate of the mold box;

[0028] The left support II is connected to the rocker II and the left side plate of the mold box;

[0029] The linkage relationship is: when the rocker arm I rotates around the axis of the small shaft I, it drives the small shaft I to rotate, and then drives the rocker I, the left support I, the rocker II, the right support I, and the rocker arm II to rotate, and drives the left side plate of the mold box to rotate around the axis of the small shaft I away from the bottom plate of the mold box, so as to achieve the effect of moving the left side plate of the mold box away from the double-leaf cigarette box;

[0030] Wherein, the small shaft II passes through the rocker arm III, the middle fixed bracket, the rocker III, and the rocker IV in sequence from back to front;

[0031] The two ends of the intermediate fixed bracket are respectively connected to the small shaft I and the small shaft II;

[0032] The right support II connects the rocker III and the right side plate of the mold box;

[0033] The right support I connects the rocker IV and the right side plate of the mold box;

[0034] The bearing is connected to the pin of the rocker arm I, so that the bearing can drive the rocker arm I to rotate, thereby driving the small shaft I to rotate;

[0035] One end of the connecting rod is connected to the rocker arm II, and the other end is connected to the rocker arm III;

[0036] The linkage relationship is: when the bearing is subjected to external force, it drives the rocker arm I to rotate around the axis of the small shaft I, and then drives the small shaft I to rotate around its own axis, and at the same time drives the rocker arm II to rotate away from the bottom plate of the mold box, the rocker arm I pulls the connecting rod to produce displacement, the connecting rod drives the rocker arm III to rotate around the axis of the small shaft II, the rocker arm III drives the small shaft II to rotate around its own axis, and then drives the rocker arm III, the right support II, the rocker arm IV, and the right support I to rotate around the axis of the small shaft II, and drives the right side plate of the mold box to rotate away from the bottom plate of the mold box;

[0037] The linkage relationship generated when the bearing is subjected to external force forms a certain opening angle between the left plate of the mold box and the right plate of the mold box, and the tension spring is stretched to present a state of bearing tension.

[0038] The stopper is mounted on the middle fixed bracket and can abut against the side wall of the rocker arm II. The rotation angle of the rocker arm II is limited by the stopper, so as to limit the maximum opening angle between the left plate of the mold box and the right plate of the mold box.

[0039] One end of the tension spring is installed on the middle fixed bracket through a tension spring rod, and the other end is installed on the rocker arm III through a tension spring shaft.

[0040] When the bearing is no longer subjected to external force, the tension spring will recover from the stretched state to the unstressed state.

[0042] Preferably, the left side plate and the right side plate of the mold box are long strip side plates. The purpose is that the length dimension of the double-leaf cigarette box will not be restricted in the direction parallel to the left side plate and the right side plate of the mold box.

[0043] Preferably, a spring is installed between the right support II and the right side plate of the mold box, and a spring is also installed between the right support I and the right side plate of the mold box. One purpose is to accommodate a double-leaf cigarette box with a width of 80 to 95 mm between the left side plate and the right side plate of the mold box without any adjustment; the second purpose is that the spring can produce a buffering effect to avoid squeezing or damaging the double-leaf cigarette box while maintaining a certain pressure.

[0044] Preferably, the left support I, the left support II, the right support II, and the right support I are L-shaped plates.

[0045] Preferably, the mold box further comprises: a mold box mounting bracket mounted below the mold box bottom plate.

[0046] Preferably, the bearing is connected to a pin, and one end of the pin is connected to the rocker arm I.

[0047] Preferably, the filling device further comprises: a carton filling mechanism for pressing the cigarette packs into the empty carton.

[0048] The carton filling mechanism can use any existing suitable clamping and filling equipment, such as a robot, as long as it can put the cigarette packs into the carton.

During the whole process, the folio cigarette carton is filled on an endless synchronous belt;

[0052] The filling method comprises the following steps:

[0053] The first mold box release mechanism opens the mold box on the synchronous belt station AA, places the strip box into the mold box, and the first mold box release mechanism stops working, and the mold box automatically tightens and clamps the strip box;

[0054] The mold box is driven by the synchronous belt to convey the strip box to the downstream station B, so that the strip box is inverted under the action of gravity, and the left and right box covers are automatically opened, and the strip box becomes open. At this time, the dry bags in the strip box automatically fall from the box to the collection box below;

[0055] The synchronous belt conveys the opened strip box to the downstream workstation C, and the strip box is rotated 180 degrees and placed upright on the synchronous belt, and the strip box remains in the opened state;

[0056] The mold box is clamped to maintain the upright state of the carton, and the synchronous belt conveys the carton to the downstream station D, and the filling mechanism presses the cigarette pack into the empty opened carton;

[0057] The synchronous belt conveys the opened strip box to the downstream workstation E, and the strip box cover closing mechanism is used to automatically close the left side cover of the strip box;

[0058] The synchronous belt conveys the opened strip box to a downstream workstation F, and the strip box cover closing mechanism is used to automatically close the right side cover of the strip box;

[0060] Preferably, the right box cover and the left box cover are both L-shaped.

[0061] Preferably, when on the synchronous belt, an imaging detection system is provided to detect the strip box to determine the state of the strip box.

[0062] The above technical solutions can be freely combined under the premise of no contradiction.

[0063] The present invention has the following beneficial effects:

[0064] 1. The filling equipment for cigarette split-type strip boxes of the present invention has a compact structure, a simple process method, is easy to control, and has a high degree of automation. The mold box used to clamp the strip box only needs to rotate the bearing to control the clamping and loosening operations of the mold box, and can also adapt to cigarette split-type strip boxes of various lengths and widths. In particular, the present invention cleverly designs a vertically arranged synchronous belt, so that the strip box can be inverted during transmission, and when the box cover is opened, the drying bag inside it automatically falls off, avoiding the complex operation of using a separate mechanism such as a positioning mechanism to locate the position of the drying bag, and then using a manipulator to take out the drying bag.

[0107] A filling method for a cigarette split-type carton, which uses the above-mentioned filling device, the cigarette split-type carton 60 to be used is in a closed state, and a drying bag 10 is stored therein to ensure the dryness of the box. During the whole process, the cigarette split-type carton 60 is filled on the endless synchronous belt 4;

[0108] The filling method comprises the following steps:

[0109] In the first step, when the mold box 8 on the synchronous belt 4 is transported to the workstation A, the bearing 19 on the mold box 8 rotates under the action of the cylinder, and the mold box 8 is opened by the action of the connecting rod 32, so that the empty strip box 60 can enter, and the tension spring 35 is in a stretched state. Then the cylinder stops working, the tension spring 35 is reset, and the left and right side plates of the mold box 8 are closed under the action of the tension spring 35 to clamp the strip box 60;

[0110] In the second step, when the mold box 8 is transported to the workstation B, the strip box 60 is inverted under the action of gravity, and after the left and right box covers are automatically opened, the empty strip box 60 becomes open, and at this time, the drying bag 10 in the strip box 60 automatically falls out of the box;

[0111] In the third step, when the mold box 8 is transported to the workstation C, the synchronous belt 4 transports the opened strip box 60 to the next workstation, and the strip box 60 is rotated 180 degrees and placed upright on the synchronous belt 4. After the detection system detects that the strip box 60 is in place, the associated process of filling is started;

[0112] Step 4: The mold box 8 continues to be transported. When it reaches the workstation D, a filling mechanism (not shown) presses the cigarette packs 50 of two rows, five packs per row, into the empty carton box 60;

[0113] Step 5: When the strip box 60 reaches the workstation E, the left cover of the strip box 60 is closed by the blocking operation of the baffle of the strip box cover closing mechanism 7;

[0114] Step 6: When the strip box 60 is transported to the work station F, the right cover of the strip box 60 is closed by the blocking operation of the baffle of the strip box cover closing mechanism 7, and the closing action of the strip box 60 is completed to become a closed state;

[0115] Step 7. When the strip box 60 is transported to the workstation G, the bearing 19 on the mold box 8 rotates under the action of the cylinder. The left and right side plates of the mold box 8 open through the action of the connecting rod 32, and the tension spring 35 becomes stretched, so that the strip box 60 is moved out to the next mechanism for the remaining processes.
