Description

The present invention relates to an apparatus for producing a package, particularly to an apparatus for continuously producing a package in which contents are filled between a pair of packaging materials that are overlapped and sent in the length direction. The present invention relates to a packaging material manufacturing apparatus using two types of packaging materials having different thicknesses, hardnesses or materials.

Subdivided packaging that wraps contents that require hygiene management, such as foods and pharmaceuticals, in small amounts of about one dose is widely used, but in order to make the contents more hygienic and easier to take out. As described in Japanese Patent Publication No. 55-36552, a filling portion is formed between a flat strip-shaped packaging material (sheet material) and a flexible packaging material (sheet material) attached to one side surface thereof, and the filling portion thereof is formed. A folded-open package in which a flat band-shaped packaging material is provided with an opening portion that is opened by breaking is well known, and the package is opened simply by bending the package and the contents are discharged by the pressure of the bending.

Conventionally, when a product made of such a bent-open package is manufactured, an open portion is formed by crimping or adhering a notch (or an opening) formed in a flat strip-shaped packaging material. There is.

Therefore, in order to continuously produce a large amount, it is not easy to secure high productivity because the number of steps is increased and the control of the sealing property is troublesome, and the contents to be filled are also limited.

Further, Japanese Patent Application Laid-Open No. 2015-101370 describes a thick-walled portion having a hardness that allows it to be folded in half, and a pair of thin-walled portions that are thinner and more flexible than the thick-walled portion. And, the accommodating portion formed between the facing surfaces of the pair of thin-walled bodies and accommodating the contents, and the foil-shaped sealing material which is broken by the bending operation of the thick-walled portions, and the contents A break-open structure of a break-open package in which a part of the enclosed package can be broken-open and the contents can be taken out from the package is presented, and examples of the sealing material include aluminum foil and stainless foil. , Copper foil, iron foil, resin film made of polyvinylidene chloride, etc. are described to be composed of a thin foil body.

However, the fracture-open package thick-walled sheet presented in Japanese Patent Application Laid-Open No. 2015-101370 is composed of a hard material such as a metal leaf having a hardness that allows it to be folded in half, and the sealing material is hard. The material is integrally bonded so as to cover both the front and back surfaces, and the heat conduction is poor and welding is difficult.

Therefore, the manufacturing method includes a sheet separation step provided with a sheet separating device, a sheet attaching step provided with a sheet attaching device, a sheet punching step provided with a sheet punching device, and a sealing material separating device. A sealing separation step, a sealing material sticking step equipped with a sealing material sticking device, a content filling step equipped with a content filling device and a film sealing device, and a packaging body provided with a packaging body separating device. The separation step is performed in this order.

That is, first, in the sheet separation step, the strip-shaped sheet wound in a roll shape is loaded into the sheet loading section, and the strip-shaped sheet unwound from the sheet loading section is supplied to the sheet separating device while being supplied by the sheet separating device. Separate into one thick sheet to produce a large number of thick sheets.

Then, in the sheet sticking step, the strip-shaped film wound in a roll shape is loaded into the film loading section, and the thin strip-shaped film unwound from the film loading section is supplied to the sheet sticking device while separating the above-mentioned sheets. The thick-walled sheets separated in the step are integrally bonded one by one to one surface (the surface corresponding to the accommodating portion) of the strip film by the sheet attaching device with an adhesive. After sealing a break-opening portion with a sealing material, the outer edge portion of the thick-walled sheet separated by the thin strip-shaped film and the other thin strip-shaped film is surrounded and welded.

Therefore, it is not possible to integrally attach a large number of separated thick sheets one by one to one surface (the surface corresponding to the accommodating portion) of the strip film at an accurate position at a predetermined interval with an adhesive. It is extremely difficult and cannot be produced in large quantities and continuously.

Special Publication No. 55-36552 Japanese Unexamined Patent Publication No. 2015-101370

The present invention is intended to solve the above-mentioned problems, and since it is opened by breaking, it is easy for consumers to use, it is easy to manufacture, it is difficult for defective products to appear, and continuous manufacturing is possible, resulting in productivity. Another object of the present invention is to provide a packaging material manufacturing apparatus for producing an excellent packaging material.

The packaging material manufacturing apparatus of the present invention has a vertical sealing means for welding a pair of strip-shaped packaging materials that are overlapped and sent in the length direction in the length direction, and a filling portion between the two packaging materials. In a package manufacturing apparatus for continuously manufacturing a package filled with contents, the packing means for filling the product and a horizontal sealing means for welding both packaging materials at predetermined intervals in the width direction are provided. At least one of the pair of packaging materials is a thermoplastic resin, and the packaging body is characterized by having an opening portion that is opened by breaking.

Further, in the present invention, the at least one packaging material is manufactured when a film material having no separate notch or opening is fixed to at least one of the outer surface or the inner surface of the sheet material which is a flat member. Since the contents of the package do not come into direct contact with the sheet material due to the film material, it is possible to deal with the contents that do not want to be brought into contact with the sheet material or that the contents are to be securely sealed depending on the material of the sheet material.

Further, in the present invention, the vertical sealing means and the horizontal sealing means are composed of a pair of rollers for sandwiching the pair of overlapping packaging materials, and one of the rollers is provided with a heating means. In this case, it becomes easy to efficiently realize high sealing performance, and when each has a heating means, for example, while heating both rollers, the heating temperature of the roller on one packaging material side is set on the other packaging material side. It is particularly desirable because it is possible to achieve high sealing performance by setting the temperature lower than the temperature of the heating means.

Further, in the present invention, when a preheater that preheats the welded portion of the packaging material during transportation is provided on the upstream side close to at least one of the vertical sealing means and the horizontal sealing means, the above. The packaging material is preheated to ensure welding, and the heating time in the seal roll is shortened, so that higher productivity can be realized.

Further, in the present invention, when the package filled with the contents is divided or punched at the welding position by at least the horizontal sealing means of the horizontal sealing means and the vertical sealing means, a single dividing means is provided. Since the package can be individually separated from the continuous state after filling the contents by the apparatus, space efficiency and time efficiency can be improved, and higher productivity can be realized.

Further, in the present invention, the thicker packaging material is heated in the pre-process of at least one of the vertical sealing means and the horizontal sealing means for welding the pair of packaging materials and in the pre-process of welding the pair of packaging materials. When the packaging material is provided, for example, when the packaging material is thick, the curl can be corrected to reduce the warp of the package as a product and improve the quality.

Furthermore, in the present invention, when the processing means for projecting the at least one packaging material outward and bending it into a gutter shape is provided, the at least one packaging material is projected outward to the gutter. By bending it into a shape, the volume of the filling portion can be secured, and there is an advantage that the tip of the nozzle to be inserted between the two overlapping packaging materials when filling the contents can be easily inserted or moved.

Further, when each of the pair of rollers forming the vertical sealing means for welding the pair of packaging materials is provided with an individual driving means, and the driving of each roller and the rotation speed can be adjusted individually. , The feed rate and feed rate of each packaging material can be adjusted, and welding can be performed by making finer adjustments.

Further, when the outer diameters of the parts shown in the following (a) to (c) are all Φ60 mm or more, the stress applied to the packaging material is reduced by allowing a margin in the bending diameter at each location. It is possible to avoid the occurrence of cracks due to stress, supply failure, etc., and enable stable production.

The block diagram which simplified and showed the characteristic part of the manufacturing apparatus of the package of FIG. An example of the packaging material used in the embodiment shown in FIG. 1 is shown, (a) is a diagram showing a packaging material for a bent-open package, and (b) is a package for a tear-open package. The figure which shows. An example of a guide portion used in the embodiment shown in FIG. 1 is shown, (a) is a front view, (b) is an explanatory view showing a usage state, and (c) is AA of (b). Sectional view along the line. An explanatory view showing a usage state of a guide portion having a heating function used in the embodiment shown in FIG. 1. The schematic which shows the different embodiment of this invention.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

FIG. 1 shows a configuration of a package manufacturing apparatus 1 according to the present embodiment in a vertical cross-sectional view, and FIG. 2 shows an extracted characteristic portion of the package manufacturing apparatus 1. The package manufacturing device 1 is a device suitable for continuously manufacturing a folded-open package 5 in which the opening portion 313 opens by bending and breaking and discharges the contents filled in the filling portion. is there.

The folded-open package 5 is formed of a pair of strip-shaped packaging materials 20 and 30 that are overlapped and sent in the length direction, and seals openings 311 provided in advance at predetermined intervals in the length direction. A thick flat strip-shaped packaging material 30 made of a sheet material 31 which is a thick flat resin having thermoplasticity provided with an opening portion 313 (see FIG. 3) sealed with the material 312 (see FIG. 3A). A flexible strip-shaped packaging material 20 made of a film material 21 which is a soft resin thinner and more flexible than the sheet material 31 is welded to the outer edge side of the material, and the filling portion formed between them is filled with the contents. It is sealed.

Further, the packaging material 30 constituting the bent-open packaging body 5 is integrally fixed to the inner surface of the sheet material 31 with a film (not shown) having no other thin strip-shaped notch (or opening). It may be the one that has been done.

In this way, in the packaging body manufactured by using the packaging material 30 in which the film material is fixed to the inner surface of the sheet material 31, the contents do not directly touch the sheet material 31 by the film material, so that the sheet Depending on the material of the material 31, it is possible to deal with the contents that do not want to be in contact with each other or that want to be securely sealed.

When the film material is attached to the outer surface, for example, when printing or the like is performed, many kinds of products having different appearances can be easily and inexpensively provided by using the same package.

Since the film material 21 constituting the packaging material 20 is a thin and flexible material, it can be used as a raw material wound around the drum 200 in advance. Further, with respect to the packaging material 30, since the sheet material 31, which is a thick flat member, has a certain degree of flexibility and can be wound, it is wound around the drum 300 in advance like the packaging material 20. It can be used as a raw fabric.

The packaging material 30 may be used as an original fabric obtained by providing a notch with a predetermined length and bending the packaging material 30 into a bellows fold. The original fabric of the bellows fold is, for example, a bellows original shown by a broken line in FIG. It can be used by setting it in the anti-supply unit 500.

Further, the packaging material 30 may be composed of a sheet material 32 which is a thick flat member in which opening portions 322 made of cuts 321 are provided at predetermined intervals (see FIG. 3B). Here, the notch 321 may be formed in advance, or may be provided at the same time when the individual packages are divided by the dividing means described later.

By using the packaging material 30 made of the sheet material 32, a tear-opening package that can take out the contents filled in the filling portion by opening the opening portion 322 by the tearing operation with the notch 321 as the base end. It can be manufactured.

Reference numerals 35 shown in FIGS. 3A and 3B are registration marks for the registration mark sensor.

In the present embodiment, the packaging materials 30 and 20 are formed to have a width for producing a vertical row of packages, but may be wide so that a plurality of packages can be produced at the same time (. Not shown).

As the material constituting the sheet materials 31 and 32, a thermoplastic resin having a certain thickness and hardness such as polyethylene terephthalate is suitable.

Reference numerals 201 and 301 shown in FIG. 1 are feed rollers for feeding out the packaging materials 20 and 30 from the drums 200 and 300, and reference numerals 202, 203, 204, 302 and 303 smooth the packaging materials 20 and 30. It is a guide roller provided for relaying to supply to.

With reference to FIG. 2, the package manufacturing apparatus 1 of the present embodiment is overlapped by a pair of pulleys 7a and 7b and fed in the length direction (vertically fed downward as shown) having different thicknesses. Between a pair of rollers 4a and 4b (vertical seal rolls) as a vertical sealing means for welding a pair of packaging materials 20 and 30 in the length direction and both packaging materials 20 and 30 which have been welded into a tubular shape. A nozzle 6 as a filling means for filling the contents, and rollers 8a and 8b (horizontal seal rolls) as a horizontal sealing means for welding the tubular packaging materials 20 and 30 in the width direction at predetermined intervals in the longitudinal direction. Below, rollers 9a and 9b (cooling rolls) for cooling the horizontal sealing position by the horizontal sealing means, and roll cutters 10a and 10b as the dividing means for dividing at the horizontal sealing position are provided.

Further, in the present embodiment, the above-described vertical seal roll and horizontal seal roll are provided with heaters as heating means only on the rollers 4a and 8a on the packaging material 20 side, and are heated from the packaging material 20 side. A method of welding is adopted.

It has been found by experiments by the inventors of the present application that the sealing work is completed efficiently in a short time when the packaging material 20 is heated and welded to the packaging material 30. Of course, when both the vertical seal roll and the horizontal seal roll are provided with heaters having a variable drive and heat amount, the versatility of the material of the package to be manufactured is expanded.

As the welding method, not only heat sealing but also various welding methods such as impulse sealing and ultrasonic sealing can be used.

Further, in the package manufacturing apparatus 1 of the present embodiment, a preheater that preheats the welded portions of the packaging materials 20 and 30 being conveyed to the upstream side close to the vertical seal roll and the horizontal seal roll. Another feature is that 41 and 42 are arranged respectively, which shortens the heating time in both seal rolls and makes it possible to realize higher productivity.

Further, in the present embodiment, in the pre-process of welding the pair of packaging materials 20 and 30, a heating roller (not shown) which is a heating means for correcting the curl by sandwiching and heating the packaging materials 30 is used. A guide portion 60, which is a processing means, is provided adjacent to the downstream side of the heating roller (see FIG. 4).

The guide portion 60 is composed of a pair of round bar members 61, 62 in which bent portions 63, 63 having a predetermined shape are formed in the central portion in the length direction by overlapping with each other (see FIG. 4A), and is formed by the heating roller. Both the front and back surfaces of the heated packaging material 30 are sandwiched between the round bar members 61 and 62, and the packaging material 30 is projected outward and bent into a gutter shape (FIGS. 4B, 4), c) See).

By using the guide portion 60, for example, the packaging material 30 which is harder and less likely to warp than a conventional flexible film packaging material is bent into a gutter shape protruding outward to increase the volume of the filling portion. The film can be easily secured and the tip of the nozzle 6 to be inserted between the pair of packaging materials overlapped when filling the contents can be easily inserted or moved to prevent the filling state from being biased. It is possible to avoid troubles that cause wrinkles in the material 21 and to secure a situation in which a high-quality product can be easily manufactured.

Further, the guide portion 70 having a heating function may be used (see FIG. 5). The guide portion 70 is composed of a block material 71 having a convex portion 73 formed in the central portion in the length direction and a block material 72 having a concave portion 74 formed in the central portion in the length direction, and the block materials 71 and 72 are inside. A heating means 75 is provided, and both the front and back surfaces of the packaging material 30 heated by the heating means 75 are sandwiched between the block materials 71 and 72, and the packaging material 30 is projected outward and bent into a gutter shape. It is something to do.

According to the guide portion 70, it is not necessary to separately provide the heating roller, which saves space, and the heating means and the processing means can be integrated to perform heating and pressurization at the same time, so that it is more stable. The packaging material 30 can be projected outward and bent into a gutter shape.

As the heating means, Joule heat, steam, hot air, gas, and various other heat sources can be used.

Further, in the present embodiment, the pair of rollers 4a and 4b forming the pair of vertical sealing means are individually provided with a drive source (electric motor or the like, not shown) having a variable drive and rotation speed. Since the rotation speeds of the rollers 4a and 4b can be individually adjusted and the feed rates and feed amounts of the packaging materials 20 and 30 can be adjusted, further fine adjustments have been made. Welding is possible.

In order to adjust the rotation speed of the pair of rollers 4a and 4b, it is preferable to adjust the feed rate and the feed amount of the packaging materials 20 and 30 by using a registration mark sensor or image processing ( Not shown).

On the other hand, in the roll cutters 10a and 10b that separate the continuous packaging 51, which is continuously sealed vertically and horizontally and sealed with the contents, one by one at the horizontal sealing position, the individual bent and opened packages are opened. In addition to separating into the package 5, R-cutting is also performed at the corners thereof. In order to ensure the accuracy of the cutting position of the roll cutters 10a and 10b, it is preferable that the cut position can be accurately detected by using a register mark sensor or image processing.

Further, the dividing means is not limited to the roll cutters 10a and 10b, and may be, for example, punching by a conventionally known punch and die method (not shown). At this time, since the present invention uses the packaging material 30 having a certain degree of hardness, punching can be easily performed as compared with a package in which films are bonded to each other, and in the case of punching, accuracy is achieved. It is possible to perform R-cut well, and it is particularly desirable that the folded-open package 5 can prevent the occurrence of defects due to piercing by R-cutting the four corners.

FIG. 6 is a diagram showing different packaging manufacturing devices 2 of the present invention, wherein the packaging manufacturing device 2 is compared with the packaging manufacturing device 1 of the embodiment shown in FIG. The supply paths from the drums 200 and 300 around which the raw fabrics of the packaging materials 20 and 30 are wound to the supply to the rollers 4a and 4b which are the vertical sealing means are different.

More specifically, two guide rollers 202 and 203 are provided between the drum 200 and the feed roller 201 for feeding the packaging material 20 from the drum 200, and three guides are provided behind the feed roller 201. Rollers 204, 205, 206 are provided.

Further, two guide rollers 302 and 303 are provided between the drum 300 and the feed roller 301 for feeding the packaging material 30 from the drum 300, and two guide rollers 304, are provided behind the feed roller 301. 305 is provided.

By changing the arrangement of the feed rollers 201, 301 and the guide rollers 202, 203, 204, 205, 206, 302, 303, 304, 305 in this way, the packaging material 30 is stressed particularly in the supply of the packaging material 30. It is difficult to apply and stable supply is possible.

Further, the drums 200 and 300 themselves may be rotated to feed out the packaging materials 20 and 30 wound around the drums 200 and 300.

Again, referring to the overall configuration of the packaging material manufacturing apparatus 1 of FIG. 1, in the present embodiment, the packaging material 30 is configured to be welded to the packaging material 20 with a vertical seal roll. The drums 200 and 300 around which the original fabrics of the packaging materials 20 and 30 are wound are arranged in the apparatus in a state of being wound in different directions (clockwise and counterclockwise).

As a result, the warpage of the material generated by the winding around the drums 200 and 300 is opposite to each other, and when the two are welded together and integrated, they cancel each other out and the warp is less likely to occur. It is possible to secure a state in which the opening portion is difficult to open. In particular, the drum 300 around which the original fabric of the packaging material 30 is wound has an inner diameter larger than that of a general drum 300, and is in a state where warpage is unlikely to occur.

The orientation of the drums 200 and 300 is not limited to this, and can be changed according to the orientation in which the original fabrics of the packaging materials 20 and 30 are wound.

Further, the drum 400 located at the bottom is for winding up and collecting the punched skeleton, but all of the drums 200, 300, 400 are in the middle in the height direction of the present manufacturing apparatus. It is located on the lower side from the position, and is designed for convenience in the work of exchanging the original fabric and the work of collecting the skeleton.

Further, the shaft of the drum 300 around which the packaging material 30 is wound, the feed roller 301 provided for feeding the packaging material 30 from the drum 300 around which the packaging material 30 is wound, and the packaging. The outer diameters of the guide rollers 302 and 303 provided in the path until the material 30 is supplied to the rollers 4a and 4b, which are the vertical sealing means, are all set to Φ60 mm or more, and the bending diameter at each location is set. Since the stress applied to the packaging material 30 is reduced with a margin, it is possible to avoid the occurrence of cracks and poor supply due to the stress and enable stable production.

As a means for aligning the pair of packaging materials 20 and 30 while eliminating the vertical deviation, the well-known method shown in the conventional example can be applied as it is. Further, in the above-described embodiment, the case of manufacturing the folded-open package 5 or the tear-open package that is opened by breaking has been described, but the package manufacturing apparatus 1 of the present invention has a different thickness and material. It is also possible to carry out a packaging body in which the contents are simply filled between two packaging materials.

Further, in the present embodiment, the case where packaging materials having different thickness, hardness and material are used for the pair of packaging materials constituting the packaging body has been described, but packaging materials having the same thickness, hardness or material are used. It is also possible.

As described above, among the pair of packaging materials, the manufacturing apparatus for continuously producing a package by filling and sealing the contents in the filling portion formed by welding the pair of packaging materials between them. At least one of the packaging materials is a thermoplastic resin, and since the opening portions opened by breaking are provided at predetermined intervals in the length direction, the opening portion can be easily broken by opening the opening portion by breaking. It is possible to provide a packaging material manufacturing apparatus that can take out the contents, is easy to manufacture, is unlikely to produce defective products, is capable of continuous manufacturing, and is excellent in productivity.
