Example 2
In the above example 1, the first wrapping films 4 were wound around the front, rear, and upper and lower surfaces of the cigarette bundle 2, however, only the left and right side surfaces of the cigarette bundle 2 around which the first wrapping films are wound are exposed, and there is a possibility that the tobacco sticks may come off from the left and right side surfaces, and the exposure of the left and right side surfaces also affects the appearance of the package of the whole cigarette bundle, and therefore, in the present invention, a technique of wrapping both the front, rear, upper, rear, right and left side surfaces of the cigarette bundle 2 with wrapping films is studied, and hereinafter, the following example 2 will be specifically described.
In example 2, after the film wrapping of the front, rear, upper and lower surfaces of the pack 2 in example 1 was performed, then, the film wrapping of the pack 2 including the peripheral surfaces of the left and right sides was performed, that is, the first wrapping film and the second wrapping film were wound in a cross shape on the pack 2.
The package shaping apparatus used in example 2 has substantially the same configuration as that of example 1, but differs in the direction of movement, and hereinafter, only the difference will be described with emphasis, and the same or similar contents may be referred to the description of example 1, and a detailed description thereof will be omitted.
The package shaping apparatus of embodiment 2 further comprises: a second conveying mechanism for conveying the stack from the first wrapping position to a second temporary placement position; the second material pushing mechanism is arranged on one side of the tobacco stack in the left-right direction of the second temporary placement position and used for pushing the tobacco stack to the second packaging position from the other side in the left-right direction; the second film feeding mechanism is used for erecting a second packaging film along the vertical direction of the cigarette stack, so that the second packaging film is opposite to the second material pushing mechanism through the cigarette stack and is positioned between a second temporary placing position and a second packaging position; and a second packaging mechanism for packaging a second packaging film on the left and right surfaces, the upper and lower surfaces in the left-right direction of the tobacco pile at a second packaging position, the second packaging film having a base film and a glue coating area on one side of the base film, the second film feeding mechanism making the glue coating area opposite to the second material pushing mechanism across the tobacco pile.

The second conveying mechanism 1203, with a structure similar to that of the first conveying mechanism 3, conveys the tobacco stacks 2, on which the wrapping of the first wrapping film has been completed, to a second temporary placement position, specifically, a position between the second pusher 1205 and the second wrapping mechanism 1223 in the figure. The second pusher mechanism, the second film feeding mechanism, and the second sealing mechanism are not shown in the figures, but the same structures as those in embodiment 1 are employed, and the description thereof is omitted. The pushing direction of the second pushing mechanism 1205 is perpendicular to the pushing direction of the first pushing mechanism 5. When the stack 2 is conveyed from the first wrapping position to the second temporary placement position by the second conveying mechanism 1203, the second pusher mechanism 1205 pushes the left side surface (the upper side surface in fig. 12) of the stack 2 by the pusher plate, so that the right side surface of the stack 2 moves rightward (downward in fig. 12) and abuts against the inner side surface of the second wrapping film and continues to push to the second wrapping position (the position where the second wrapping mechanism 1223 is located in the figure). The second packing mechanism 1223 is for packing the second packing film on the right and left surfaces in the left-right direction and the upper and lower surfaces in the up-down direction of the cigarette stack at the second packing position. In this embodiment 2, as the second pusher 1205 pushes the cigarette stack, the right surface of the cigarette stack abuts against the inner surface of the second wrapping film and pushes the second wrapping film to move to the right, and the second film feeding mechanism discharges the second wrapping film so that the right surface, the upper surface, and the lower surface of the cigarette stack are surrounded by the second wrapping film in the second wrapping position.
In addition, the second wrapping mechanism is provided with a second sealing and cutting mechanism for pressing and adhering the second wrapping film to the left surface of the cigarette stack 2. The specific structure of the second sealing and cutting mechanism can be referred to the first sealing and cutting mechanism 7, and the main difference is that the installation direction is perpendicular to the first sealing and cutting mechanism 7, and the description is omitted here.
In example 2, the following modifications may be made: the positions of the second pusher 1205 and the second wrapping mechanism 1223 in figure 12 may also be interchanged, i.e., the second pusher 1205 is located on the right side of the stack and the second wrapping mechanism 1223 is located on the left side of the stack, the second pusher pushing against the right surface of the stack to push the stack 2 to the left.

That is, unlike the arrangement of the second pusher 1205 and the second sealing mechanism 1223 in fig. 12, the second pusher 1205, the second packaging film, and the second sealing mechanism 1223 are arranged in series with the first pusher 5, the first packaging film, and the first sealing mechanism in the conveying direction of the first conveying mechanism 3. In order to avoid interference between the conveyed cigarette stack and the second pushing mechanism 1205, the second pushing mechanism 1205 can be retreated in a lifting and left-right moving mode. During the conveying by the second conveying mechanism 1203, the tobacco pile 2 is rotated by 90 degrees about the axis in the up-down direction by the vertical rotating mechanism so that the right or left surface faces forward in the conveying direction, that is, faces the inner surface of the second wrapping film.
In example 2, the following modifications may be made: as shown in fig. 13, the second transport mechanism is arranged in two stages at right angles, the first stage is provided along the pushing direction of the first pusher 5, and the second stage is arranged perpendicular to the first stage and is provided with a rotary table 1331 at a right angle position. The stack is rotated 90 degrees about the vertical axis on the rotary table 1331 so that the front and rear surfaces are forward and rearward of the conveying direction in the second stage. The second pushing mechanism 1305 and the second wrapping mechanism 1323 are respectively located on both sides of the second section and are arranged in parallel with the first pushing mechanism 5 and the first wrapping mechanism, and at the second temporary placement position, the left and right surfaces of the cigarette stack respectively face the second pushing mechanism 1305 and the second wrapping mechanism 1323, i.e., the left surface or the right surface of the cigarette stack faces the inner surface of the second wrapping film.
The beneficial effects of adopting the embodiment 2 are as follows: realize that packing plastic equipment is automatic to carry out pad pasting and plastic work with the cross to box-like thing, improve automatic, reduce user intensity of labour, improve work efficiency, simultaneously, the outward appearance of cigarette buttress extranal packing is good, and each face of cigarette buttress all is covered by the packing film, and the welt is difficult to deviate from in the cigarette buttress.

The package shaping apparatus used in example 3 has substantially the same configuration as that of the package shaping apparatus used in example 1, but differs in the movement direction, and hereinafter, only different contents will be described with emphasis on the description, and for the same or similar contents, the description of example 1 may be referred to, and a detailed description thereof will be omitted.
The package shaping apparatus of embodiment 3 further comprising: a second conveying mechanism for conveying the stack from the first wrapping position to a second temporary placement position; the second material pushing mechanism is arranged on one side of the cigarette stack at the second temporary placement position and used for pushing the cigarette stack to the second packaging position; a second film feeding mechanism which spans a second packaging film between the second temporary placement position and the second packaging position so that the second packaging film is opposite to the second pushing mechanism through the cigarette stack; and a second packaging mechanism for packaging a second packaging film on the left and right surfaces in the left-right direction and the front and rear surfaces in the front-rear direction of the pack at a second packaging position, the second packaging film having a base film and a glue application region on one side of the base film, the second film feeding mechanism making the glue application region opposite to the second pushing mechanism across the pack.
In order to install a second packaging film on the left surface, the right surface, the front surface and the rear surface of the cigarette stack in the left-right direction, the front surface and the rear surface in the front-back direction, a second conveying mechanism conveys the cigarette stack from a first packaging position to a second temporary placing position along the pushing direction of a first material pushing mechanism, the first packaging film at the first temporary placing position, a second material pushing mechanism and the second packaging film at the second temporary placing position are sequentially arranged in a straight line in the pushing direction of the first material pushing mechanism, the second material pushing mechanism is arranged on the rear side of the cigarette stack at the second temporary placing position in the front-back direction, the pushing direction of the second material pushing mechanism is the same as the pushing direction of the first material pushing mechanism, and the second material pushing mechanism is used for pushing the cigarette stack to the second packaging position to the front side in the front-back direction; the second film conveying mechanism is used for erecting a second packaging film along the left and right directions of the cigarette stack, the erecting direction of the second packaging film is the same as that of the first packaging film, the second conveying mechanism is provided with a vertical rotating mechanism between the first packaging position and the second temporary placement position, and the vertical rotating mechanism is used for enabling the cigarette stack to rotate 90 degrees around the axis in the front-back direction. That is, unlike the arrangement of the second pusher 1205 and the second sealing mechanism 1223 in fig. 12, the second pusher 1205, the second packaging film, and the second sealing mechanism 1223 are arranged in series with the first pusher 5, the first packaging film, and the first sealing mechanism in the conveying direction of the first conveying mechanism 3. In order to avoid interference between the conveyed cigarette stack and the second pushing mechanism 1205, the second pushing mechanism 1205 can be retreated in a lifting and left-right moving mode. During the conveying process by the second conveying mechanism 1203, the tobacco pile 2 is rotated by 90 degrees about the axis in the front-rear direction by the vertical rotating mechanism so that the front-rear surface is still positioned in the front-rear direction but the right surface or the left surface faces upward, i.e., the left and right surfaces are interchanged with the upper and lower surfaces.
In example 3, the following modifications may be made: in order to mount the second packaging film on the left and right surfaces in the left-right direction and the front and rear surfaces in the front-rear direction of the cigarette stack, the pushing directions of the first pushing mechanism and the second pushing mechanism are perpendicular as shown in fig. 12, and the second conveying mechanism is provided with a vertical rotating mechanism between the first packaging position and the second temporary placement position, the vertical rotating mechanism being configured to rotate the cigarette stack by 90 degrees around the axis in the left-right direction so that the right side surface of the cigarette stack faces the inner surface of the second packaging film but the front surface or the rear surface faces upward, that is, the front surface and the rear surface are interchanged with the upper surface and the lower surface.
The beneficial effects of adopting the embodiment 3 are as follows: in addition to the effects of embodiment 2 described above, there is provided an alternative arrangement of the respective mechanisms in the apparatus, which can be freely selected according to the site, the structure of the apparatus itself, the size of the cigarette pile, and the like.
Example 4
In embodiment 4, a material blocking device is further arranged between the first packaging position and the second temporary placement position, the material blocking device is provided with a liftable baffle, and a predetermined gap is formed between the lower surface of the liftable baffle and the upper surface of the second conveying mechanism; when the cigarette stack can pass through the predetermined gap, the second conveying mechanism passes the cigarette stack through between the second pushing mechanism and the second packaging film, and directly conveys the cigarette stack to a position on the downstream side of the second temporary placement position in the second conveying mechanism. The baffle 1224 of the material stopping device is shown in fig. 1, and it should be noted that the liftable baffle 1224 is arranged above the second conveying mechanism 1203, when the second conveying mechanism 1203 conveys the cigarette stacks to the second temporary placement position, the liftable baffle 1224 blocks the cigarette stacks, then the second pushing mechanism 1205 pushes the cigarette stacks to the second packaging position, and the second packaging mechanism 1223 is used for performing the second film wrapping and packaging.
The predetermined gap below the liftable baffles allows the tobacco stacks with smaller heights to pass through, and at the moment, the tobacco stacks with smaller heights are conveyed to the downstream side of the second conveying mechanism 1203 in a state of only winding the first packaging film without passing through the second film wrapping package.
The beneficial effects of adopting the embodiment 4 are as follows: to the less cigarette buttress of volume, can freely select to wrap up in the membrane packing once, can accelerate production rhythm, raise the efficiency.
Example 5
In the case of packing the first wrapping film and the second wrapping film in a cross shape as in examples 2 and 3, since each side surface of the tobacco bundle is covered with the wrapping film and the surface of the tobacco bundle is hardly exposed, the cuff fitting performed when packing the first wrapping film in example 1 is not essential and can be omitted. In example 5, the width of the first wrapping film may be set to approximately coincide with the width of the front and back surfaces of the stack so that the left and right edges of the wrapping film do not substantially extend beyond the left and right edges of the front and back surfaces of the stack, i.e., the first wrapping film does not create cuffs. Also, the width of the second wrapping film may be set to approximately coincide with the width of the left and right surfaces of the stack so that the front and rear edges of the wrapping film do not substantially exceed the front and rear edges of the left and right surfaces of the stack, i.e., the second wrapping film does not create cuffs. Accordingly, the reforming mechanism may be omitted from the package reforming apparatus.
The beneficial effects of adopting the embodiment 5 are as follows: because the processing procedure of the cuff is omitted, the production rhythm can be accelerated, the efficiency is improved, and meanwhile, the equipment structure is simplified.
Example 6
In the case of packing the first wrapping film and the second wrapping film in a cross shape as in examples 2 and 3, the outer portion of the first wrapping film is further covered with the second wrapping film, and the second wrapping film is attached to the stack on the left and right sides of the stack to fix the rods to each other by adhesive force, and therefore, the first wrapping film does not necessarily have a glue-coated area. In example 6, the first packaging film was provided with only the base film, the second packaging film was provided with the base film and the glue-coated area on one side of the base film, and the second film feeding mechanism faced the glue-coated area toward the pack. The first packaging film adopts a film without glue on two sides, fastening force is applied to the tobacco stack by utilizing the elasticity of the film and the pressure applied during sealing and cutting, but the second packaging film adopts a glue film with a glue coating area on a single side.
The beneficial effects of adopting the embodiment 6 are as follows: because first wrapping film adopts the membrane that the two sides do not have the glue, can save the cost, simultaneously, can utilize the second wrapping film to ensure the fixity ability to each cigarette strip in the tobacco bale.
Example 7
In the case where the first wrapping film and the second wrapping film were wrapped in a cross shape and no cuff treatment was performed as in example 2, there were portions where the edge of the first wrapping film and the edge of the second wrapping film were adjacent to each other and did not overlap each other at 4 ridge lines of the cigarette bundle, that is, 4 mutually parallel ridge lines of the cigarette bundle were exposed from the wrapping films. In example 7, the width of the first wrapping film was the same as the width of the front and back surfaces of the stack, the width of the second wrapping film was the same as the width of the left and right sides of the stack, and 4 ridges of the stack were exposed between the left and right edges of the first wrapping film and the front and back edges of the second wrapping film, and the stacking direction of the tobacco rods in the stack was set so that the 4 ridges of the stack consisted of the longest ridges of the tobacco rods.
In example 3, in the case where the first wrapping film and the second wrapping film were wrapped in a cross shape and no cuff treatment was performed, in example 7, the width of the first wrapping film was the same as the width of the front surface and the rear surface of the tobacco pile, the width of the second wrapping film was the same as the height of the left side surface and the right side surface of the tobacco pile, 4 ridge lines of the tobacco pile were exposed between the left and right edges of the first wrapping film and the upper and lower edges of the second wrapping film, and the stacking direction of the tobacco rods in the tobacco pile was set so that the 4 ridge lines of the tobacco pile consisted of the longest ridge line of the tobacco rods in the tobacco pile.
The beneficial effects of adopting the above embodiment 7 are: since the longest side of the tobacco rod in the pack becomes the ridge line exposed from the packaging film, the tobacco rod is less likely to protrude from the packaging film than in the case where the shortest side of the tobacco rod becomes the ridge line exposed from the packaging film, and therefore, the appearance of the pack of tobacco is easily ensured.
Example 8
In the case of packing the first and second wrapping films in a cross shape as in examples 2 and 3, the wrapping and shaping apparatus further includes a return mechanism for returning the tobacco pile from the second wrapping position to a position downstream of the second temporary placement position in the second conveying mechanism.
