Description

The present invention relates to a packaging machine and a packaging method .

  There is a packaging machine that manufactures a package by wrapping the surroundings of a package to be conveyed with a packaging film, and sealing and cutting a predetermined position of the packaging film. For example, there is a printer in which a printing machine is provided in a transport path of a strip-shaped packaging film before wrapping an article to be packaged, and a date of manufacture is printed and stamped at a predetermined position of the packaging film in the middle of transport. If the printing area is relatively small, such as the date of manufacture, and if the contents printed throughout the day do not change once the packaging machine is started, the printing machine can be relatively small. It does not get in the way even if set to.

  On the other hand, for example, there is a demand for printing a serial number or a barcode on a package that stores the packaged items in order to perform individual management of the packaged items. In order to satisfy such a requirement, the contents of printing change every time, so the above-described printing machine that prints the fixed numbers cannot cope. Furthermore, a conventional printing machine that prints simple characters such as numbers cannot print barcodes in the first place.

  Furthermore, the packaging film of the packaging body may be subjected to various designs such as product names and advertisements related to products in a state visible from the outside. The design of each paper is usually printed on the packaging film itself, and a raw roll on which the printed packaging film is wound is set in a packaging machine, and packaging processing is performed. However, if the item to be packaged is a product that is actively produced in a variety of small quantities, the printed packaging film will not be in time for printing on the packaging film, or will not be used when the product ends and will be disposed of. For the purpose of suppressing the occurrence of the above, there are some which manufacture a seal printed with a product name and attach the seal to a packaging film.

  For example, if the product is a medicine, the appearance of generics leads to a very wide variety of products, and it is necessary to display different designs and designs for each product, and there is a need to print lot numbers and serial numbers. It becomes more prominent.

  On the other hand, for example, as in the packaging device disclosed in Patent Document 1, there is a device in which a printer is mounted on a packaging machine to perform inline printing. In the in-line printing, various characters and designs are printed on a belt-shaped packaging film in the middle of conveyance by a printing machine. Therefore, it is possible to respond to changes in the printing contents according to the contents of the products that the printing contents change every time such as the serial number and the barcode described above and the contents of the product that the item change is actively performed. Can meet the demand.

Japanese Patent No. 2850998

  However, since the packaging machine corresponding to the in-line printing system disclosed in the above-described Patent Document 1 performs printing by placing ink on the surface of the packaging film, the following new problem occurs. That is, when printing is performed on the surface of the packaging film by in-line printing, the printed contents may be removed by, for example, rubbing the printed portion or dissolving with a solvent. Although it is possible to make it difficult to remove the printed contents by devising various types of ink and printing methods, mischief and tampering cannot be prevented as long as printing is performed with ink. Furthermore, in order to perform inline printing, it is necessary to install a large printing press, which is not preferable because the entire apparatus becomes large.

In order to solve the above-described problems, the packaging machine of the present invention includes (1) a film supply means for supplying a belt-shaped packaging film, a means for storing an article to be packaged using at least the packaging film, and the packaging object. In a packaging machine comprising: sealing means for sealing a predetermined position of the packaging film containing an article; and a cutting means for cutting the predetermined position of the packaging film, the packaging film before containing the article to be packaged Printed matter supply means for supplying a printed matter on which information on the article to be packaged is printed, overfilm supplying means for supplying a belt-like overfilm on the packaging film so as to cover the printed matter, Adhering the over film and the packaging film to hold the printed material between the over film and the packaging film Comprising an adhesive means, wherein the over-film is visible film the information printed on the printed material while covering the printed material from the outside, the over film and the packaging film by the sealing means Was also sealed. The printed matter corresponds to the printed paper piece 21 or the like in the embodiment. The packaging film corresponds to the main film 5 in the embodiment. In the embodiment, since the present invention is applied to the pillow packaging machine, the main film is formed into a cylindrical shape to wrap the article to be packaged. However, the present invention is not limited to this, and for example, a film different from the packaging film is prepared. However, the article to be packaged may be accommodated by the other film and the packaging film.

  Since the surface of the printed material is covered with an over film, the printed content is not removed by rubbing the surface of the printed material or using a solvent, etc., and the over film is adhered to the packaging film. Will not be removed. Therefore, it is possible to prevent tampering with respect to the package manufactured by the packaging machine, more specifically, the printed matter.

  (2) The printed matter supply means may include a printing function, and the printed matter may be printed by the printing function. In this way, for example, even if the packaging machine is in operation, the display content of each printed matter can be made different, and for example, information unique to the packaged item such as a lot number can be printed. Further, even when the packaging machine is in operation, even if it is the same print content, the print content can be easily changed, so that it is possible to respond quickly to changes in the product.

(3) In the packaging method according to the present invention, a printed material on which information on an object to be packaged is printed on a belt-shaped packaging film in the middle of conveyance, and a belt-shaped overfilm is formed on the packaging film so as to cover the printed material. The over film and the packaging film are adhered to each other and the printed matter is held between the over film and the packaging film, and the over film is printed on the printed matter in a state of covering the printed matter. the information is visible films from outside, it performs a packaging process for the articles to be packaged by using the packaging film adhered to at least the over-film, and so as to produce a package.

  In the present invention, since the printed matter is covered and protected by the overfilm, tampering can be prevented.

Further, the film supply device 2 arranges various rollers 7 at predetermined positions from the original fabric roll 6 to the packaging machine main body 1, and the main film 5 fed from the original fabric roll 6 is passed over the rollers 7. Then, it is guided to the packaging machine main body 1 through a predetermined path. The roller 7 includes a tension roller that applies tension to the main film 5 and a free roller that changes the transport direction of the main film 5 and guides the transport. In the present invention, it is not always necessary to link the drive motor to the original roll 6, and a feed roller may be provided on the transport path of the main film 5 and pulled out.

  The packaging machine body 1 includes a bag making device 12 on the carry-in side. The bag making device 12 allows the main film 5 continuously supplied from the film supply device 2 to pass therethrough so that both side edge portions 5a of the main film 5 are brought into contact with each other (polymerization), and the tube is formed into a cylindrical shape. Bag-like film 14 is made. Further, the articles to be packaged 3 that are sequentially supplied from the article to be packaged conveyance supply device 4 to the packaging machine body 1 are inserted into the bag making machine 12. Thereby, the to-be-packaged goods 3 supplied to the bag making machine 12 are arrange | positioned in the cylindrical film 14 for every predetermined space | interval.

  Further, the packaging machine main body 1 has a center seal device that heat-seals the film polymerization end of the tubular film that has passed through the bag making device 12 and is formed into a tubular shape downstream of the bag making device 12 along the direction of travel. 13 is provided. The center seal device 13 includes a pair of pinch rollers 13a that sandwich and convey a portion where the both side edges of the tubular film 14 are overlapped to give a conveying force, and a heat seal that sandwiches the overlapped portion from both sides. A pair of bar-shaped sealers 13b and a pair of press rollers that are arranged downstream of the sealer 13b, pressurize and superimpose the overlapped portions of the side edges of the heated and melted film, and complete the heat seal 13c. Here, the bar-shaped sealer 13b is used, but there is also a structure constituted by a pair of disk-shaped sealers, and various structures can be taken.

  A top seal device 15 is arranged on the downstream side of the center seal device 13. The top seal device 15 seals and cuts the tubular film 14 in a direction perpendicular to the traveling direction, that is, in a transverse direction. In the top seal device 15, a pair of top sealers 15 a arranged up and down revolves along a predetermined locus while maintaining a state where the seal surfaces 15 a ′ are opposed to each other. That is, the pair of top sealers 15a move at the same speed in synchronization with the conveyance of the tubular film 14 with the tubular film 14 sandwiched from above and below, and seal the tubular film 14 in the lateral direction. In addition, a cutter blade is built in the top sealer 15a to cut the seal portion. Thereby, the front-end | tip part (part which encloses the top product) of a cylindrical film is isolate | separated, and the package 16 is manufactured. And this package 16 is conveyed on the carrying-out conveyor apparatus 17 arrange | positioned in the downstream of the top seal apparatus 15. FIG. In the present embodiment, the top seal device 15 uses a box motion type in which a pair of top sealers 15a revolve around a predetermined locus while maintaining a state where the seal surfaces 15a 'face each other. It is preferable to use a rotary type or other various sealing devices.

  Here, in the present invention, the paper feeding device 20 is provided in the film feeding device 2 so that the paper strip 21 can be fed onto the main film 5 in the middle of conveyance. The paper piece 21 is a paper sheet piece having a rectangular shape or an arbitrary outer shape. The surface of the paper piece 21 may be printed with contents relating to the package 3 such as various characters and designs such as designs. The paper piece feeder 20 stores, for example, a plurality of paper pieces 21 in a stacked state, and discharges the plurality of paper pieces 21 one by one. Alternatively, a roll of roll-shaped paper may be provided, and a paper piece 21 may be manufactured and discharged by cutting it at a predetermined length from the leading end pulled out of the band. In the present embodiment, the paper piece 21 is placed on the main film 5 without being temporarily fixed or pasted, so that the paper piece feeder 20 moves the main film 5 in the horizontal direction in the film supply device 2. It was installed above the area.

  Further, in the present embodiment, a stamping device 22 for printing on the surface of the paper piece 21 is provided. The stamping device 22 is a device that prints a lot number, expiration date, expiration date, bar code, and the like on the surface of the paper piece 21 being discharged. By using the marking device 22, different information can be printed for each piece of paper 21. A piece of paper 21 printed by the marking device 22 is regularly supplied onto the main film 5.

  An overfilm supply device 25 is disposed on the downstream side of the paper piece feeder 20. The overfilm supply device 25 supplies the strip-shaped overfilm 23 so as to overlap the main film 5 on which the paper piece 21 is placed. The overfilm supply device 25 includes a support unit for an overfilm original roll 24 obtained by winding a belt-shaped overfilm 23 in a roll shape. The instruction means is constituted by a rotation support shaft 26, for example. The overfilm original fabric roll 24 is inserted into the rotation support shaft 26 and fixed. The rotation support shaft 26 is also linked to a drive motor (not shown) and rotates in response to the rotational force of the drive motor. With the rotation of the rotation support shaft 26, the overfilm original fabric roll 24 also rotates, and the overfilm 23 is fed out. The drive motor is controlled so that the overfilm 23 is fed out in synchronization with the movement of the main film 5.

  The over film 23 is a transparent film, and the film width is longer than at least the width of the paper piece 21 (the length in the direction perpendicular to the conveying direction of the main film 5 when placed on the main film 5). ing. When the overfilm 23 is supplied so as to overlap the main film 5, the entire surface of the paper piece 21 is covered with the overfilm 23 and is sandwiched between the overfilm 23 and the main film 5. Moreover, since the over film 23 is a transparent film, the paper piece 21 covered with the over film 23 becomes visible from the outside (see FIG. 2).

  A heater roller 28 is disposed on the downstream side of the overfilm supply device 25. The over roller 23 is heated by the heater roller 28 and heat-sealed with the main film 5. Thereby, the over film 23 and the main film 5 adhere | attach on the periphery of the paper piece 21, and the paper piece 21 is pinched | interposed and fixed between both films.

  Thus, since the over film 23 is thermally bonded to and integrated with the main film 5, the over film 23 moves together with the main film 5 thereafter. That is, the over film 23 is transported in a state of being bonded to the outer surface of the tubular film 14 that is made by passing through the bag making machine 12, and is orthogonal to the transport direction of the over film 23 by the top seal device 15. It is heated and pressurized over the entire surface in the width direction, heat-sealed to the top seal portion of the main film 5, and sealed more securely.

  Thereby, the package 16 manufactured through the top seal device 15 is coupled with the fact that both ends 23a of the over film 23 are fused to the top seal portion 16a as shown in FIG. The package 16 is not peeled off. Therefore, the paper piece 21 is protected by the over film 23, the paper piece 21 is not peeled off, and the content printed on the paper piece 21 is not rubbed or peeled off by the solvent, thereby preventing a break. it can. That is, it is possible to provide a falsification preventing function with a simple mechanism as compared with a stamping method in which printing is performed directly on the surface of the film or an online printing machine.

  In the present embodiment, the paper piece 21 is placed on the main film 5 without being temporarily fixed or pasted. However, the present invention is not limited to this, and the paper piece 21 is placed on the main film 5. It may be fixed by bonding or the like. For example, instead of the paper piece 21, a label with glue attached to the back surface may be used, and the label may be attached by a label feeder.

  Further, the paper piece 21 is a paper sheet having a rectangular shape or an arbitrary outer shape, but the material is arbitrary, and various types such as a film and a sheet can be used. When printing on a film, if the printed surface is directly exposed to the outside, the printed portion may be rubbed off due to rubbing or the like.

In the above-described embodiment, the stamping device 22 is provided. However, the present invention does not necessarily include the stamping device. That is, a piece of paper, a label, or the like that has been subjected to predetermined printing may be prepared and used.
Moreover, in embodiment mentioned above, although applied to the pillow packaging machine, the packaging machine to apply is not restricted to a pillow packaging machine, It can apply to various things.

  As another example 1, an over film having a mirror character printed on the inside by a stamping apparatus may be bonded onto the main film. As another example 2, an adhesive is applied to two or more pieces of paper and temporarily fixed. Because it will rotate if you stop at one point. As another example 3, a piece of paper may be charged with static electricity and positioned on the main film by electrostatic attraction (for example, Japanese Patent No. 3307663). Another example 4 is a package in which at least one unsealed portion on both outer sides of the overfilm at the end of the top seal portion is provided with an opening cut (for example, Japanese Patent Application Laid-Open No. 2007-106488).
