Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used in the field of filling and packaging technology, and particularly relates to a filling and packaging apparatus for filling a tubular film packaging material with contents.

[Conventional technology]

Contents such as food are filled and packaged in a tubular film packaging material. In particular, in the case of food, a tubular film packaging material (hereinafter simply referred to as “film packaging material”) is used as a packaging material in order to package the food in an aseptic condition. This film packaging material is formed by drawing out a plastic material as a thin cylindrical bag while applying internal pressure, and then flattening the inner surfaces thereof by contacting each other and preparing it for use in, for example, a roll-shaped raw material. Things. Since the film packaging material is completely sealed in a bag shape except for the beginning and end, no bacteria enter from the outside. At the time of use, i.e., at the time of filling and packaging, the side edges of the film packaging material are cut off during running, the contents are filled from there, and the side edges are sealed immediately after the filling position, and the film is also refilled. Are sealed and cut in the width direction at appropriately set intervals in the longitudinal direction, so that packages as products are obtained one after another. In such a filling and packaging apparatus, when one sheet is completed, the operation of the apparatus is temporarily stopped, a new sheet is loaded, and the film packaging material is drawn out from the apparatus, and for example, if the starting end is sealed, this is cut. And then set it on the device.

Therefore, when a new web is set, the film wrapping material of the new web is manually guided again from the start end between a series of guide rollers of the apparatus, and further, the position in the width direction is re-positioned. Time-consuming work was being performed. Several types of film splicing methods are known in the form of filling a general single film while forming it into a tube with a forming plate.
A connecting method is not known for the above-mentioned film packaging material having a tubular shape from the beginning. Furthermore, the filling tube cannot be inserted in the film packaging material in which the start end (and the end) is sealed. In addition, if the above operation is performed after opening and closing the seal portion at the start end, there is a possibility that bacteria may enter the film packaging material before filling. Therefore, the applicant filed Japanese Patent Application No. 63-1566.
No. 85 (JP-A-02-0219210), there has been proposed a device capable of filling and packaging a film packaging material connected by an automatic film packaging material connecting device without performing the above-mentioned reworking operation.

This apparatus is provided with an incision means for incising a side edge of the film packaging material while the film packaging material is running, and at a cutting start position, a filling tube is made to face the film packaging material from the side, and the filling tube is opened. A sealing means for sealing the cut portion of the film wrapping material at a position immediately after the film wrapping material, and furthermore, the end portion of the film wrapping material and a new film wrapping material of the new raw material are provided between the cutting means and the raw material. Is provided with a connecting device for connecting the starting end portion to the starting end portion by welding. As a preferred embodiment, such a conventional apparatus is configured such that, at a position above the insertion position of the filling tube into the film packaging material, the inner surfaces of the film which come into contact with each other at the opening rear edge of the film packaging material formed by cutting the joint portion are cut off. A separating means having a conical head is attached to the filling tube in the film wrapping material so as to be easily separated and guided to the filling tube.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a schematic configuration of the apparatus of this embodiment.

In the drawing, reference numerals 1 and 1A denote a raw material obtained by flattening a tube-shaped material and then winding it in a roll shape, and both are always disposed so that one of the raw materials is used and then the other is used. A film wrapping material F is drawn out from one of the webs (the web 1 in the drawing), and the starting end thereof is connected to the terminal end of the film wrapping material F of the previous web by thermal welding by the connection device 2.

The connecting device 2 is formed by a pair of upper and lower heating bars, each having a blade body attached to the front surface and the rear surface, and manually pulling the end portion and the starting end projecting back and forth after heat welding. Thereby, it can be cut off by the blade body.

The guide rollers 3 and 4 and the sterilizing liquid tank 5 are disposed at the end of the connecting device 2. The germicidal solution tank 5 and various devices to be described later provided therefrom are provided in a so-called sterile room. A roller 6 is provided in the sterilizing liquid tank 5, and the running direction of the film packaging material F is changed upward. Immediately above the sterilizing solution tank 5, a member 7 is provided for scraping the sterilizing solution adhering to the surface of the film packaging material while the film packaging material is being lifted, the edges being in contact with both surfaces of the film packaging material. ing.

Next, guide rollers 11, 12A, 12B for changing the running direction of the film packaging material in the horizontal direction and then downward are provided at the raised position of the film packaging material. The film packaging material F whose traveling direction has been changed downward is fed by feed rollers 14A,
Both side edges are squeezed and conveyed by the feeding means 14 consisting of 14B and run downward.

Immediately before the guide roller 12A, a knife 15 is provided as a cutting means for cutting a side edge (right edge in the drawing) of the film packaging material to be run. The knife 15 is capable of reciprocating in the width direction of the film packaging material. If necessary, the knife 15 makes one reciprocation while the film packaging material is running to move the connecting portion F 'of the film packaging material on the side opposite to the position of the knife 15. The incised portion is formed by cutting out the side edge portion, and also serves as a cutting device.

On the other hand, in FIG. 1, two piston pumps 18 and 19 are disposed on the hopper 16 via a switching valve 17 at the upper right side of the guide rollers 12A and 12B. The filling tube 20 extends downward so as to send out. The filling tube 20 is inserted into the inside of the film packaging material F which is bent and cut in the lateral direction at a position below the guide roller 12B, and has a nozzle body 21 which extends vertically and opens downward at the tip. doing. The nozzle body 21 has a conical head 22A at an upper position above a position where the filling tube 20 enters the film packaging material. In the present embodiment, the head 22A is formed integrally with the nozzle body 21. Here, it is desirable that the outer diameter of the base of the conical head 22A be larger than the diameter of the filling tube 20. Further, the head 22A and the nozzle body 21 are provided with a fin-shaped guide member 22B for guiding an inner edge of the film packaging material on the side opposite to the incision portion, and together with the head 22A, the separation means 22 is provided. Has made. The guide member 22B extends from the side of the nozzle body 21 to the head 22A, and its upper end reaches the position immediately above the top of the conical head 22A.

Immediately below the connection portion of the filling tube 20 to the nozzle body 21, a pressing roller 23 for pressing the two films of the cut film packaging material is disposed. At the side edge of the film, a heating body 24 for heating the film while pressing the film, and a roll-shaped seal body 25 are sequentially arranged as sealing means, and the cut film packaging material F is fed under the seal body 25. It is adapted to be sealed while being sent downward by means 14.

Below the nozzle body 21, there is provided a horizontally long ironing roller 26 which intermittently presses the film packaging material filled with the content from both sides to form an ironed portion where no content exists. Immediately below that, in synchronization with the ironing roller 26, the film wrapping material is pressed down while being lowered at the same speed as the feed speed of the film wrapping material to seal the ironing portion in the width (lateral) direction. A known seal unit 27 that reciprocates up and down is provided. In this embodiment, two adjacent linear seal portions are formed. Further, below the seal unit 27, a known separating unit 28 having a blade 28A for cutting between the two adjacent linear seal portions in synchronization therewith is provided.

Reference numeral 29 denotes a chute for transporting the separated products one by one to a predetermined position.

In this embodiment, if there is a slight gap between the films at the rear edge of the opening of the cut-out portion, a thin fin-shaped guide member can enter between the films and separate the films, but the films adhere to each other. If this occurs, or if the connection at the side edge of the cutout opening is disengaged from the guide member, it may no longer be possible to separate the film and guide it to the nozzle. This is solved in the embodiment of the present invention.

Therefore, in the present embodiment, in order to solve this problem,
As shown in FIG. 9A, in addition to the separating means 22 comprising a head 22A and a guide member 22B, two films are cut from the both sides at the rear edge of the opening of the cut-out portion above the guide member 22B. A widening means comprising a widening member 31 for widening the two, and a bar-shaped widening guide member 32 which enters from the side between two films widened immediately below the widening member 31. 30 are provided.

Next, the operation of the apparatus of this embodiment as described above will be described.

First, the running of the film packaging material is temporarily stopped, and the end portions and the start ends of the two webs are joined by the joining device 2 by heat welding in a state of being overlapped. Then, in the case of the present embodiment, the portion that protrudes forward and backward is cut off by a blade body (not shown).

The film packaging material F thus joined and integrated is passed through the guide rollers 3 and 4 and is sterilized in the sterilizing liquid tank 5 while changing the running direction of the film packaging material F upward.
The sterilizing liquid adhered to the film packaging material F traveling upward is scraped off by the member 7.

After that, the film packaging material F is guided by the guide rollers 11, 12A, 12B.
Is sent downward by the feeding means 14 (feed rollers 14A and 14B). At this time, the side edge of the film packaging material F is cut off during traveling by the knife 15 immediately before the guide roller 12A, and the film packaging material F is cut. Then, the cut long ear-shaped pieces _Fz are picked up by a roller or the like (not shown) and disposed.

Thereafter, the film wrapping material passes through the guide roller 12A, and when the connecting portion F 'comes to the position of the cutting means (knife) 15, the running speed of the film wrapping material is not reduced or is reduced, so that the knife 15 is moved. The portion F 'is cut off by one reciprocation in the width direction of the material (FIG. 2). At this time, the side edges of the film packaging material opposite to the incision side remain connected. Next, when the trailing edge of the cutout opening F ″ reaches the head 22A of the nozzle body, the running speed of the film packaging material is temporarily reduced or stopped, and the trailing edge of the opening is expanded by the expanding member 31. And a guide opening material between the films
The trailing edge of the opening is surely guided to the nozzle 21 via the head 22B so that 32 enters. Therefore, according to the present embodiment, even if the opening rear edge of the cutout opening F ″ is in close contact, and further, the connecting portion F ′ is displaced from the guide member 22B, the above-described opening member 31 and the opening By guide material 32,
The upper end of the fin-shaped guide member 22B surely enters the rear edge of the opening, and the film is separated. After that, the head 22A
The widening member 31 finishes the widening operation, and the widening guide member 32 retreats from the widening position of the film, so that the running state of the film packaging material F is not hindered. The film packaging material starts running at a steady speed again.

Thus, in the film packaging material, the two films are separated by the conical head 22A. At this time, since the maximum diameter of the head portion 22A is larger than the diameter of the filling tube 20, the cutout portion on the right side edge of the film packaging material is sufficiently opened and the filling tube 20 is opened.
From inconvenient forces from Then, the separation of the two films is gradually transmitted in the width direction by the head 22A as the vehicle runs. Then, the opposite side of the incised portion, that is, the left side edge is guided by the fin-shaped guide member 22B, and the film packaging material is fed without skewing. The separation between the two films is symmetrical in the width direction,
Moreover, since the interval is gradually widened, wrinkles and the like do not occur. After the film packaging material completely surrounds the nozzle and the running is stabilized, the opening widening guide material 32 is pulled out from between the films.

The cut portion of the film packaging material f is
Immediately below the connection portion, the sheet is squeezed by the squeezing roller 23, and then heated by the heating body 24, and then sealed by the seal body 25 to form a tube again.

On the other hand, in the filling tube 20, the raw material as the content in the hopper is supplied from alternately operated piston pumps 18, 19 to the switching valve 17.
The above-mentioned contents are filled from the lower opening of the nozzle body 21 into the film packaging material F which has been intermittently fed through the tube and has become a tubular shape again.

Thereafter, the film wrapping material filled with the contents is locally formed with an ironing roller 26 by an ironing roller 26, and this portion is then sealed by a sealing unit 27 and then cut off by a separating unit 28 to be separated one by one. One product falls on the chute 29.

[Effect of the invention]

As described above, in the present invention, a conical head is provided above the nozzle and a fin-shaped guide member is provided immediately above the head as a separating means, and the opening means is provided immediately before the separating means. Even if the trailing edge of the cutout opening at the joint portion of the film packaging material is in close contact, or the joint portion is disengaged from the guide member, the film packaging material can be guided to the nozzle, so there is no need for manual guiding work. Work efficiency may be improved.
