Abstract

PURPOSE:To perform decorative packaging while coping with various types of bottles with different heights by a method wherein a long container with different diameters for the top and bottom such as a sake bottle, etc., is packaged by a packaging material for which a lamella material such as paper, rayon paper, unwoven fabric, etc., is joined with a heat-shrinkable film. CONSTITUTION:A packaging material 2 is wound around a container 1 which is stood with its smaller diameter part 1' up, and after heat-welding the wound end part extending its total length, the bottom is wrapped heat-shrinking the packaging material 2 which is hanging from the bottom of the container 1 by a necessary length, by hot air. Then, after the packaging material 2 is joined to the peripheral wall of the container 1 by drawing and eliminating air in the cylindrical shaped packaging material 2 at the upper part of the container 1, the packaging material 2 on the top of the container 1 is twisted from the upper end, and the upper part from the twisted part is folded down. The folded packaging material 2 is temporarily fixed, and after tying by a tying material at a location which is lower than the temporarily fixed location, the temporary fixing is released. The packaging mechanism is integrally movable in the vertical direction.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention can be used to manufacture vertically long containers such as liquor bottles, beer bottles, soft drink bottles, etc. whose upper and lower portions have different diameters, using thin materials such as paper, nonwoven fabric, etc., and heat-shrinkable films. The present invention relates to a method for cosmetic packaging using laminated packaging materials (hereinafter simply referred to as packaging materials).

0002

[Prior Art] Bottles of sake, for example, are normally displayed and sold unwrapped, but some are decoratively wrapped in Japanese paper or Japanese paper-like packaging materials. This is done manually, and in a small number of cases cosmetic packaging is done mechanically, but this is done with the bottle lying on its side, which is extremely inefficient. For this reason, the present inventors have invented a method of packaging cosmetics in an upright position in order to efficiently package cosmetics. (See Japanese Patent Application No. 1-147792)

0003

[Problem to be Solved by the Invention] According to the present invention, for example, there is no difference in cosmetic packaging between a 1-sho bottle and a 5-go bottle, but there is a difference in the height of a 1-sho bottle and a 5-go bottle. Because of the difference in packaging, when attempting to package upright bottles, the mechanism of the machinery used for this purpose is specified and designed on the premise that the size of the bottle to be packaged is constant. Because of that,
It has to be exclusive to a single variety. If we want to create a product that can be used as cosmetic packaging for many types of bottles with different heights, we will need to adapt the various mechanisms necessary for cosmetic packaging to fit many different types of bottles. There is no alternative but to provide additional adjustment functions to adjust each part of the mechanism, but this complicates the mechanism, increases the cost of the machine, and makes it difficult to handle.

[0004] This invention provides a cosmetic packaging method that can be easily switched and adjusted as needed so that containers of different heights can be cosmetically packaged when the upright containers invented earlier are cosmetically packaged. The purpose is to

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the cosmetic packaging method of the present invention covers containers such as liquor bottles, which are vertically long and have different diameters at the top and bottom, using paper, rayon paper, non-woven fabric, etc. When packaging with a packaging material made by laminating a thin sheet material and a heat-shrinkable film, the packaging material is wrapped with the container standing upright with the small diameter portion facing up, and the wrapped ends are heat-sealed over the entire length. After that, the packaging material that hangs down from the bottom of the container to the required length is heat-shrinked using heated air to wrap around the bottom.
Next, the air in the cylindrical packaging material at the top of the container is removed by suction to bring the packaging material into close contact with the container peripheral wall, and then the upper packaging material is twisted from the upper end of the container, and then the upper part is collapsed from the twisted part, and the collapsed packaging material is In this method, cosmetic packaging is performed by fixing a container in a fixed position, tightening it with a tightening material downward from the fixed point, and then releasing the fixed fixing. The packaging material is hung from the container and cut to a certain length.
A mechanism that wraps the container from both ends while pressing it against the container, heat-seals the ends of the wrapped packaging material over the entire length, and a mechanism that heat-seals the ends of the wrapped packaging material over the entire length and hangs down the required length from the bottom of the container. A hot air injection port passage mechanism for a container, which causes a container wrapped in a certain packaging material to pass over a heated air injection port to heat-shrink the hanging packaging material and wrap the bottom of the container; and a cylindrical upper part of the container. A mechanism that suctions and eliminates the air in the packaging material that has been placed in the container and brings the packaging material into close contact with the peripheral wall of the container, a mechanism that twists the upper packaging material from the top end of the container and collapses the upper part from the twisted part, and a mechanism that fixes this collapse. It is possible to adjust the mechanism to move up and down at the same time, and the mechanism to release the fixation after tightening with a tightening material downward from the fixation point, and by adjusting the vertical movement, it is possible to adjust the vertical movement of the mechanism. This is a cosmetic packaging method for a vertically irregularly shaped container that can be used for cosmetic packaging for a wide variety of bottles.

[0006] The packaging material used in this invention is a material made by laminating a thin material such as paper, rayon paper, non-woven fabric, etc. with a uniaxially or biaxially stretched heat-shrinkable film. The shrinkable film may be any ordinary heat-shrinkable film, and for example, uniaxially or biaxially stretched films of polyamide, polyester, polypropylene, vinyl chloride, styrene, etc. are used. In addition, examples of thin materials to be laminated to this include Japanese paper,
Western paper, rayon paper, synthetic paper, wet-processed or dry-processed nonwoven fabric, etc. are used. The method for laminating this thin sheet material and the heat-shrinkable film is arbitrary, but if heat is used for lamination, it is a matter of course that it should be done at a temperature within a range that does not cause the heat-shrinkable film to shrink. .

The thin sheet material used in this invention is usually about 10 to 50 g/m2, preferably within 100 μm, and the heat-shrinkable film to be attached thereto has a thickness of about 10 to 50 μm and is heated at 100 to 250°C. So 15
% or less is preferably used. Also, when the packaged container is displayed as a product in a store,
It is best to use a transparent heat-shrinkable film so that the label affixed to the container can be easily seen through the packaging material; if such a need is not recognized, an opaque film should be used. There is no problem.

In this invention, in order to be able to adjust the vertical movement all at once, a necessary mechanism is built into the box-like body, which is only a frame, and this box-like body is moved by appropriate means. It may be possible to move it up and down. By clearly indicating the relationship between the set position of the box and the size of the container, when packaging a container of the required size, the box can be moved up and down to the position specified by the size. Just make it match.

[Operation] This invention wraps a vertically long container, such as a liquor bottle, with different diameters at the top and bottom, using a packaging material made by laminating a thin material such as paper, rayon paper, nonwoven fabric, etc., and a heat-shrinkable film. To do this, wrap the packaging material around the container while it stands upright with the small diameter part facing upwards, heat-seal the wrapped ends over the entire length, and then blow the packaging material that hangs down the required length from the bottom of the container into heated air. After that, the air in the cylindrical packaging material at the top of the container is removed by suction to bring the packaging material into close contact with the peripheral wall of the container, and then the upper packaging material is twisted from the top of the container, and then the packaging material is wrapped from the twisted part. In this method, the upper part of the packaging material is laid down, the collapsed packaging material is clamped, the clamping material is tightened downward from the clamping point, and then the clamping is released to perform cosmetic packaging. A position sensor for positioning and a position sensor for the positioned container.
A mechanism that hangs down the packaging material, cuts it to a certain length, presses it against the container, wraps the container from both ends, and heat-seals the ends of the wrapped packaging material along its entire length. The container is wrapped in packaging material that is suspended from the bottom of the container by a required length, and is passed over a heated air injection port to thermally shrink the hanging packaging material to wrap around the bottom of the container. hot air injection nozzle passage mechanism;
a mechanism for suctioning and eliminating air in the cylindrical packaging material at the top of the container to bring the packaging material into close contact with the peripheral wall of the container; and a mechanism for twisting the packaging material above the container from the top end and causing the upper part to fall down from the twisted portion; A mechanism for releasing the fixation after tightening with a tightening material downward from the fixation point can be moved up and down at the same time, so that these mechanisms can be moved up and down without making special adjustments. By adjusting each mechanism to the set position all at once, it became possible to cosmetically package a container of an appropriate size for that position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of implementing the present invention will be described with reference to the accompanying drawings.

First, the process of cosmetic packaging a container of a certain size is represented by a process diagram shown in FIG. 1 divided into A to G. That is, step A is the uprighting and positioning of the container. Next, step B is wrapping and heat-sealing the packaging material. Next, step C is heat shrinkage of the packaging material at the bottom of the container, followed by step D.
Air suction at the top of the container is eliminated during the process. Next, in step E, the packaging material above the top of the container is twisted and collapsed. Next, step F is twisting and fixing of the fallen packaging material. Then G
The process of releasing the main fixation and the temporary fixation. The cosmetic packaging is completed by Among the mechanisms for carrying out the steps A to G, this invention simultaneously integrates the mechanisms related to the height of the containers when cosmetically packaging containers with different heights, which are container sizes. This allows for vertical movement of containers of different sizes, so that when packaging containers of different sizes, the appropriate height position can be adjusted, and further, the related mechanisms can be moved up and down simultaneously. By incorporating an indicator scale into the mechanism and making adjustments according to this indicator scale, it is possible to more easily adjust the up and down mechanism to suit the size of the cosmetic packaging. Each step of the cosmetic packaging method will be explained in order.

[0012] In this explanation, a sake bottle commonly called a 1-sho bottle will be described as a container 1 that is vertically long and has different diameters at the top and bottom, and the packaging material 2 is, for example, a thin leaf material 3.
FIG. 2 shows a nonwoven fabric attached to a heat-shrinkable film 4. First, the first step is A.
In the process, as shown in Fig. 3, the container 1 has a small diameter part 1'.
It is placed on stand 5 with the side facing up. The size of the stand 5 at this time is preferably the same as the size of the bottom 1'' of the container 1, or smaller than that.The container 1 placed on the stand 5 has a position sensor 6.
The position of the container 1 in the circumferential direction is determined by this. At this time, the position sensor 6 searches for a label (not shown) attached to the container 1, for example, and moves the stand 5 so that the container 1 is at a constant position in the circumferential direction on the stand 5 based on this label. Rotate it into position. This positioning is achieved by wrapping the packaging material 2 around the container 1, as will be explained later, and by heat-sealing the side edges 2' and 2'' to each other to cosmetically package the container 1. Since 7 is a portion where both ends 2' and 2'' of the packaging material 2 overlap, it is not preferable for this double portion to overlap with a portion such as a label affixed to the container 1, so to avoid this, This is done to place the heat-sealed double portion of the packaging material in an unaffected area.

[0013] When the positioning of the container in the circumferential direction is completed in this manner, the next step B, which is wrapping and heat-sealing of the packaging material, is performed. This is illustrated in FIGS. 4-6. First, a packaging material 2 cut to a predetermined size is brought close to almost touching the container 1. This will be explained with reference to FIG. 4. The packaging material 2 that has been wound up into a roll is pulled out and suspended down via a guide 7. Numeral 8 is a suction tube that slides up and down, and has a suction hole 9 on the surface facing the hanging packaging material 2. Two suction tubes are provided on both sides of the packaging material 2 so that they can move up and down at the same time. is being used. Although not shown, this suction tube 8 is connected to a separately provided vacuum pump, and sucks outside air through a suction hole 9. Now, when the suction tube 8 is in the position shown in FIG. 4(a), the suction tube 8 is suctioning the packaging material 2. This packaging material 2
The suction tube 8 that has adsorbed the packaging material 2 then descends while adsorbing the packaging material 2, and stops descending at the position shown in (b).

The stopping position of this suction tube 8 is
This is the position of the wrapping arms 10 provided at positions facing each other. Similar to the suction tube 8, this wrapping arm 10 has a suction hole on the surface facing the packaging material 2, and the arm 10 is arranged to go half a circle around the container 1 and come together. Note that, like the suction tube, this wrapped arm also sucks outside air from the suction hole using a separately provided vacuum pump. Now, when the suction tube 8 descends while adsorbing the packaging material 2 and stops at the position of the wrapping arm 10, the cutter 11 located directly above the wrapping arm 10 moves laterally to cut the packaging material 2. . As a result, the packaging material 2 cut to a predetermined size is suctioned onto the suction tube 8. Next, the packaging material 2 is attempted to be adsorbed onto the wrapping arm 10 by suctioning air through the suction hole of the wrapping arm 10, and at the same time, the suction of the suction tube 8 that has been suctioning is stopped, and the packaging material 2 is suctioned. Adsorption is transferred from the tube 8 to the wrapping arm 10. When this transfer of suction is completed, as shown in (c), the suction tube 8 rises to a predetermined position while maintaining the state in which the packaging material 2 cut to a predetermined size is suctioned and held on the wrapping arm 10. Stop at. There, the packaging material 2 whose lower part was cut by the packaging material 2 that had descended together with the suction tube 8 in the previous operation is hanging down. Here, the vacuum pump of the suction tube 8 works again to suction the packaging material 2, and prepares the packaging material 2 to be next lowered, that is, to be delivered to the wrapping arm 10 next. At this time, the packaging material 2 is lengthened by a desired length from the upper and lower ends of the container 1 and placed in the container 1, as shown in FIG.

That is, the area above the upper end of the container 1 becomes a twisting margin, and the area below the lower end of the container 1 becomes a part that wraps around the bottom 1'' of the container and is heat-shrinkable.The packaging material 2 is a heat-shrinkable film. 4 is placed on the side of the container.The packaging material 2 is then wrapped around the container 1 and its side edges 2'
. As shown in (a) to (c), the suction arms 10 move in a semicircular manner from both sides of the container 1 while adsorbing the packaging material 2, and wrap the packaging material 2 around the container 1. ,
When the joining is completed, heat is generated over the entire length to perform thermal fusion, and for this purpose, a heating element (not shown) is incorporated in the suction arm 10. After the packaging material 2 is thus wrapped around the container 1 and wound in a stable state by heat fusion, the packaging material at the bottom of the container is thermally shrunk in Step C. This will be explained with reference to FIGS. 8(a) to 8(c). The container 1, on which the packaging material 2 has been wrapped, begins to be gripped by the air suction tube 12. This gripping is achieved by lowering the air suction tube 12 from above to the small diameter portion 1 of the container 1.
After the air suction tube 12 is fitted, a separately provided vacuum pump (not shown) operates to suction air, thereby adsorbing the container 1 onto the air suction tube 12. This air suction tube 12 also serves as a transfer tool, and as shown in FIG. 8(a), the air suction tube 12 descends and, while holding the container 1 by suction, moves to FIG. 8(b). As shown, the container 1 rises by a slight height, and then passes over the heated air jet pipe 13 as shown in FIG. 8(c), and is moved to the next platform 5. When the container 1 is initially raised by the air suction tube 12, the packaging material 2 wrapped around the container 1 is wrapped so as to hang down below the bottom 1'' of the container 1. This is to prevent the packaging material 2 hanging down from the container from coming into contact with the stand 5 during transport of the container and causing trouble in the subsequent heat shrinkage. Therefore, instead of raising the container 1, the platform 5 may be lowered while being gripped by the air suction tube 12. At this time, the heights of the stands 5 before and after the heated air jet pipe 13 may be the same. In this way, while the container 1 is being held, the heated air jet pipe 13
When passing over the top, this heated air jetting pipe 13 opens toward the bottom 1'' of the container 1, and when the container 1 is transferred, it blows out heated air. The packaging material 2 that has been hanging down further down shrinks by heat and wraps around the bottom 1'', moves further and is placed on another table 5. When the container 1 is placed on this table 5, air suction The tube 12 stops sucking air, releases its grip on the container 1, and simultaneously rises upwards.

This completes the heat shrinkage of the packaging material at the bottom of the container, which is step C, and then the suction and removal of air from the top of the container, which is step D, is carried out. This is shown in FIGS. 9(a) to 9(b). First, the container 1 is moved from the position where the bottom packaging material has completed heat shrinkage to a further advanced position. The upper part of the packaging material 2 that wraps the container 1 placed on the stand 5 in a different position is cylindrical, and an air suction tube 14 is inserted here to suction and remove the air inside the cylindrical shape. The cylindrical packaging material 2 is in close contact with the container peripheral wall. Now D
Step E, which is the process of suctioning and removing air from the upper part of the container, is completed, and then step E, which is twisting and folding the packaging material above the edge of the container, is performed. This is shown in FIGS. 9(a) to (b) and FIGS. 10(a) to (b). As shown in FIGS. 9A and 9B, two bars 15 are provided on the left and right between the upper end of the container 1 and the air suction tube 14 in this position. When the air suction 14 is performed and the packaging material 2 is brought into close contact with the container peripheral wall, the bars 12 narrow the interval and clamp the packaging material 2. This clamping of the bar 12 is shown in FIGS. 10A and 10B. The bar 12 rotates while holding the bar 12 and twists the packaging material 2. Simultaneously with this twisting of the bar 12, the air suction tube 14 is pulled upward. The container 1 is transferred from the position shown in FIG. 10(a) to the position shown in FIG. 10(b) with the packaging material 2 kept twisted. In the middle of this transfer path, a horizontal plate 16 is placed at a position approximately at the same height as the height of the container 1, and the packaging material 2 located above the upper end of the container collides with this horizontal plate 16, causing the horizontal plate to It entered the underside of 16 and was forced to collapse. This completes the twisting and folding of the packaging material above the edge of the container, which is step E. Next, step F is performed in which the twisted and collapsed packaging material is temporarily fixed in the upper part of the container.This is done, for example, by inserting a pipe into the upper part of the container 1. The material is bent downward by the fitted pipe so as to come into contact with the small diameter section 1' of the container 1. Next, the last step, step G, of final fixing and release of temporary fixing, is carried out, but this is done by using strings, metal strings, etc. to wrap the packaging material that was bent downward in the previous step and is in contact with the small diameter portion 1'. After tightening, the temporary fixing is released by releasing the pipe for temporary fixing in the previous step F, and the final product with cosmetic packaging is obtained. Become.

This invention provides a mechanism for performing each operation from process A to process G, which includes a position sensor for positioning the container to be packaged in the circumferential direction, and a position sensor for suspending the packaging material to the positioned container. A mechanism that cuts a certain length, presses it against the container, wraps the container from both ends, and heat-seals the ends of the wrapped wrapping material over the entire length; A hot air injection port passage mechanism for a container that passes a container wrapped in packaging material that is suspended by a required length over a heated air injection port, heat-shrinks the hanging packaging material and wraps the bottom of the container. a mechanism for suctioning and eliminating air in the cylindrical packaging material at the top of the container to bring the packaging material into close contact with the peripheral wall of the container; a mechanism for twisting the upper packaging material from the top end of the container and lowering the upper part from the twisted portion; The mechanism for fixing this collapse and the mechanism for releasing the fixation after tightening with a tightening material below the fixing point can be simultaneously adjusted up and down, and by adjusting the vertical movement, the height can be adjusted. It is now possible to perform cosmetic packaging for containers of various lengths and short lengths.In order to move each of these mechanisms up and down at the same time, each mechanism is built into the frame. It is best to install the body so that it can slide freely on the support. At this time, it is convenient to specify the stopping position of the frame for each type of container.

According to this method, containers of various types, that is, containers of various types with different heights, can be operated while the transport route remains at the same level, while the frame body incorporating various mechanisms is adjusted in height according to the types. This means that a single model can process a wide variety of containers.
