Description

  The present invention relates to a bag making and packaging machine, and in particular, it is possible to perform different back-pasting packaging for gluing and enveloping with a single device without replacing parts such as a former (bag making machine). It relates to a possible bag making and packaging machine.

  A bag-making packaging machine is a packaging machine that supplies fluid products in the vertical direction using gravity and fills them while making pillow-type bags, and is suitable for packaging powder, fluid, and solid roses. Yes. Specifically, the belt-like film is run in the length direction, and after positioning through the former so that the portions to be sealed at both ears in the width direction of the film face each other, the portions to be sealed are placed on the film. After sealing along the length direction (hereinafter referred to as “longitudinal seal”), the film is formed into a cylindrical shape, and the contents are filled in the film, and then in the width direction with respect to the length direction of the film Sealed (hereinafter referred to as “horizontal seal”) is used to produce a packaged product.

  There are two types of vertical seals: gluing and enveloping. Generally, as shown in FIGS. 1 and 2, a former for forming a band-like film 3 into a bag shape is used for gluing or enveloping. By exchanging them with dedicated ones, we can make a gaspaste or an envelope. That is, the palm-fitting former 1f and the envelope pasting former 1o are prepared in advance, and the former is exchanged every time the palm-fitting and envelope pasting are changed.

  Patent Document 1 includes a film transfer means for intermittently transferring a belt-like film in the flow direction and a control means for controlling the operation of the vertical seal device in the bag making and packaging machine, and the vertical seal device is in contact with the film. A heater block that seals the film, and a drive device that alternately performs a forward operation of pressing the heater block toward the film so that the heater block intermittently contacts the film and a retracting operation of separating the heater block from the film In general, a bag making and packaging machine is disclosed in which the heater block contacts the film during the transfer of the film and is controlled so that the heater block moves away from the film when the film is stopped.

  According to the bag making and packaging machine, the heater block is configured to perform the film sealing operation only during the transfer of the film without wrinkles. Therefore, the film can be prevented from being melted too much. However, it is said that a beautiful vertical seal can be obtained, and since the film is sent intermittently, the configuration of the vertical seal and other devices is extremely simplified, and the cost can be greatly reduced. Patent Document 1 describes that by changing the way the film is passed to the former, a fin seal (gap sticking) method is supported in addition to the overlap (envelope sticking) method.

  As described above, as a conventional general mechanical configuration, in order to change between gluing sticking and envelope sticking, it is necessary to replace the former, which is troublesome for the operator as well as from the viewpoint of workability. It was inefficient. On the other hand, Patent Document 1 describes that by changing the way the film is passed to the former, it supports not only the overlap (envelope sticking) method but also the fin seal (gap sticking) method. It has been suggested that it is possible to change between gluing and enveloping without changing the former.

  However, the above description of Patent Document 1 only shows the concept of changing between gluing and envelope sticking, and does not show any specific implementation technique. Therefore, when an actual bag making and packaging machine is operated, sufficient disclosure has not been made with respect to stably and reliably changing between palm-fitting and envelope-fitting without exchanging the former.

  The present invention has been made paying attention to the above circumstances, and its purpose is to stably and reliably use a single device without changing the former for different back-pasted packaging for gluing and enveloping. It is to provide specific technical means that can be performed.

  The bag-making and packaging machine of the present invention that has solved the above-mentioned problems is the positioning of the belt-like film running in the length direction so that the planned seal portions of both ears in the width direction of the film face each other via the former. Then, in the bag making and packaging machine configured to perform the step of sealing the portion to be sealed along the film length direction to form a cylinder, the outlet of the former is allowed to run the film. It is provided with a plate-shaped guide that is fixed in such a direction as to intersect the trajectory and faces a horizontal plane with respect to the film surface, or is capable of moving back and forth, or detachable, and affixes the portion to be sealed to an envelope When passing between the plate-shaped guide and the former, the one-side ear portion of the film is allowed to pass, and the other-side ear portion of the film is allowed to pass the outside of the plate-like guide, and the two sides are stuck together. Is configured such that between the plate-shaped guide and the former, the one-side ear portion of the film is turned outward and the other-side ear portion of the film are passed through, and heat sealing is performed when each film passes. It has the feature in the point.

  In the bag making and packaging machine of the present invention, it is preferable that the outlet of the former is the nearest place where the planned seal portions of the widthwise ears of the belt-shaped film face each other.

  In the bag making and packaging machine of the present invention, it is preferable that the leading edge of the plate-shaped guide has an obtuse angle.

  According to the bag making and packaging machine of the present invention, the plate-shaped guide fixed at the outlet portion of the former so as to face the horizontal surface with respect to the film surface, or can be moved back and forth, or detachable. I have. And, when pasting the seal-scheduled portion on the envelope, when passing the one-side ear portion of the film between the plate-shaped guide and the former, and passing the other-side ear portion of the film outside the plate-shaped guide and pasting on the palm Is configured such that between the plate-shaped guide and the former, the one-side ear portion of the film is folded outward and the other-side ear portion of the film are allowed to pass, and heat sealing is performed at each passage. . Therefore, different back-pasting wrapping between palm-pasting and envelope-pasting can be performed stably and reliably with a single device without replacing the former.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following specific examples, and may be implemented with modifications within a range that can meet the purpose described above and below. These are all possible and are included in the technical scope of the present invention. In the following description, the same parts are denoted by the same reference numerals.

  FIG. 3 is an external view showing a state of affixing a palm and an envelope when a bag making and packaging machine according to an embodiment of the present invention is used, and FIG. 4 uses the bag making and packaging machine according to an embodiment of the present invention. The enlarged plan view which shows the mode of the palm-pasting and envelope sticking in the case of having met is shown.

  The bag making and packaging machine (not shown) according to the embodiment of the present invention is not particularly limited, and for example, a known bag making and packaging machine described in Patent Document 1 can be used. In the embodiment of the present invention, the most characteristic feature is that the exit of the former 1 is fixed so as to face a horizontal plane with respect to the belt-like film surface in a direction intersecting with the traveling locus of the belt-like film 3, or freely movable back and forth. Or it is the point provided with the guide 2 arrange | positioned so that attachment or detachment is possible. Specifically, the outlet portion of the former 1 is a portion after the band-shaped film 3 is positioned so that the portions to be sealed at both ears in the width direction of the band-shaped film 3 face each other via the former 1. Yes, although not particularly limited, from the viewpoint of minimizing the occurrence of wrinkles and misalignment of the band-shaped film 3, the seal-scheduled portions of the widthwise ears of the band-shaped film 3 face each other. The nearest location is preferred.

  The shape of the former 1 is not particularly limited as long as it can be positioned so that the portions to be sealed of the widthwise ears of the band-shaped film 3 face each other, and is used in a normal bag making and packaging machine. You can use what you have. The material is preferably made of stainless steel from the viewpoints of durability, corrosion resistance, and the like.

  The shape of the guide 2 is preferably a plate shape in consideration of being fixed so that the horizontal surface faces the surface of the belt-like film 3, and the leading edge of the guide 2 is considered in consideration of work safety. It is more preferable that the edge is shaved so as to have an obtuse angle to form a rounded corner. The material is preferably made of stainless steel from the viewpoints of durability, corrosion resistance, and the like.

  As described above, the position of the guide 2 is always a fixed position at the exit of the former 1 when fixed, and the position of the strip-shaped film 3 passing through the guide 2 is changed so that the envelope is attached or the palm is held. Paste can be selected.

  When a part to be sealed is affixed to the palm, as shown in FIGS. 3 (a) and 4 (a), a band-like shape is formed between the guide 2 and the former 1 with one ear of the belt-like film 3 folded outward. What is necessary is just to let the other ear part of the film 3 pass. As a result, the guide 2 presses both the one-side ear portion of the belt-like film 3 folded outward and the other-side ear portion of the belt-like film 3 [3e in FIG. be able to. Here, when it demonstrates regarding turning back one side ear | edge part of the strip | belt-shaped film 3, outward, it is good to utilize the softness | flexibility which the strip | belt-shaped film 3 originally hold | maintains. In other words, since the tip of the band-shaped film 3 has a nature that is easy to bend from the beginning, in carrying out the present invention, folding one side ear of the band-shaped film 3 outward does not require any special device, It can be done easily. Once the ear is folded, the belt-like film 3 continues to be folded so as to be self-reversing while running in the longitudinal direction.

  On the other hand, when the part to be sealed is pasted on the envelope, as shown in FIGS. 3 (b) and 4 (b), the one-side ear portion of the strip-shaped film 3 is passed between the guide 2 and the former 1, and the strip-shaped film. What is necessary is just to let the other side ear | edge part of 3 pass the outer side of the guide 2. FIG. As a result, the belt-like film 3 passes through the guide 2, and the one-side ear portion [3o in FIG. 3B] and the other-side ear portion [FIG. Since 3i] in b) faces each other, a desired envelope can be attached. Note that the guide 2 can be configured to be movable forward and backward or detachable for the purpose of facilitating such operations.

  In addition, after running the strip | belt-shaped film 3 to a length direction and positioning so that the planned seal | sticker part of the width direction both ears of this strip | belt-shaped film 3 may face each other via the former 1, this seal | sticker planned part is this film The film 3 is formed into a cylindrical shape by vertically sealing along the length direction of 3, and the film 3 is filled with contents, and then transversely sealed in the width direction with respect to the length direction of the film 3. Thus, a packaged product can be produced.

  It does not specifically limit about the material of the strip | belt-shaped film 3, The packaging film used with a normal bag making packaging machine can be used. Specifically, it is possible to select a material as appropriate in consideration of the slipperiness, dimensional stability, low temperature sealing property, hot tack property, antistatic property, etc. of the film, but from the viewpoint of versatility, It is preferable to use low density polyethylene or medium / high density polyethylene.
