[Industrial applications]

 The present invention relates to a filling and packaging machine for packaging the contents of granular foods or powdery foods in small bags.

[0002]

[Prior Art]

 Some granular foods such as confectionery and powdered foods such as tea, coffee, black tea, and milk powder are packaged in small sachets (for example, tea packs) so that they can be used once. The wrapping paper used to wrap these foods in small sachets is a synthetic paper made by combining pulp and synthetic resin such as polypropylene or polyester, or a composite material made of aluminum foil and the above-mentioned synthetic resin film (hereinafter referred to as composite paper). Is used. Then, as a packaging method, this composite paper is made into a wide roll, supplied to the packaging machine from the left and right, respectively, and vertically sealed in several rows with the side sealing roll device, and then horizontally with the cross sealing roll device. Seal it. Immediately after this horizontal sealing, the contents weighed by the weighing machine fall from the chute and are filled.

By continuously performing the vertical seal and the horizontal seal, the wide left and right composite papers are individually packaged by vertically and horizontally sealing over a plurality of articles with the contents filled. Becomes In this way, the individually-wrapped composite paper that is vertically and horizontally sealed is first cut into a vertically long package with the sides sealed by cutting the middle part of the vertical seal with a slitter device. When the device cuts and separates approximately the middle part of the horizontal seal, it becomes a individually wrapped pouch with each side sealed on each side. The pouches are dropped one by one on a plurality of chutes arranged under the transverse cutting device and are supplied to a belt conveyor, and 5 to 10 pouches are packed in a carton by a cartoning machine. ing.

[0004]

[Problems to be solved by the device]

 In the conventional pouch filling and packaging machine described above, composite paper using synthetic resins such as polypropylene and polyester is heat-melted and pressure-bonded by a side sealing roll device to vertically seal, and immediately after that, a slitter device is used to intermediate the vertical seal. However, since the width of the slitter cutting surface of the slitter device is at most about 1 mm, the synthetic resin in the composite paper is not yet completely solidified at the time of cutting and after passing through the slitter device in a semi-molten state. The cutting points are partially fused again.

For this reason, the individual packets are not individually inserted into the plurality of chutes arranged under the horizontal cutting device by the horizontal cutting device, which causes a line trouble. The tendency that the above-mentioned cut portions fuse together again is particularly large in synthetic paper in which pulp and synthetic resins such as polypropylene and polyester are mixed together. In addition, the individual bags that have been separated by the horizontal cutting device and individually packaged are not inserted into the chute one by one. The cause of the line trouble is that the above-mentioned cutting points are fused and the slitter cuts by the slitter device. Since the width of the surface is very narrow as described above, there is a problem that the lower end of the cut pouch rides on the upper frame of the chute having a large width and is not smoothly inserted into the chute. Therefore, the purpose of the present invention is to obtain a pouch filling and packaging machine in which individually wrapped pouches smoothly fall into the chute and there is no line trouble.

[0006]

[Means for Solving the Problems]

 In order to achieve the above objectives, the present proposal provides the following pouch filling and packaging machine. That is, in a vertically and horizontally sealed composite paper, the contents are filled and cut by a slitter device that cuts the substantially middle portion of the vertical seal and a horizontal cutting device that cuts the substantially middle portion of the horizontal seal. In the filling and packaging machine that obtains the packed sachets, a vertical cutting slit separating blade and a sorting step roller are provided between the slitter device and the horizontal cutting device, and the individually wrapped sachets are sorted forward and backward after the horizontal cutting device. The pouch filling and packaging machine is characterized in that a plurality of squeezing drop-outs are partially overlapped and arranged in a zigzag pattern.

[0007]

[Action]

 In the small bag filling and packaging machine, the slitter device cuts the middle part of the vertical seal and the middle part of the horizontal seal is cut by the horizontal cutting device, but the vertical cutting slit separating blade and the sorting blade are distributed between the slitter device and the horizontal cutting device. Since step rollers are provided, those separated on the left and right by the slitter device are separated on the left and right by the separating blade and separated by the distribution step roller without fusing, and are separated to the front and back to the drop chute. Inserted smoothly and there are no line troubles.

【Example】

 Embodiments shown in the drawings will be described below. (1) is a raw material supply tank of the filling machine, which is dropped by a supply roll (2) into a measuring hole of a measuring plate (3) which is moved by a rack and a gear, and by moving the measuring plate (3). The measuring hole opens and the contents fall into the chute (4). Then, the wide composite material is supplied from the left and right rolls (5) and (6) to the side sealing roll devices (7) and (8). The composite material is a composite paper using a synthetic resin such as polypropylene or polyester, and when it is polymerized by the side sealing roll device (7) (8), it is hot melt pressed and vertically sealed (a) into several lines as shown in Fig. 5. It After the vertical seal (a), the melt is pressure-bonded by a cross-sealing roll device composed of rolls (9) and (10) to form a horizontal seal (b) as shown in FIG. Immediately after this horizontal seal (b), the contents weighed by the above-mentioned weighing machine fall from the chute (4) and are filled.

By continuously performing the vertical seal (a) and the horizontal seal (b), the wide left and right composite paper sheets are vertically and horizontally sealed over several rows in a state where the contents are filled. , Will be individually wrapped. In the packaging bag in which the length and width are thus sealed, first, the substantially middle portion of the vertical seal (a) is cut by a slitter device (11) (12) as shown in FIG. 5 and FIG. c) Then, it becomes a vertically long packaging form in which the sides are sealed. When this is further cut and separated (d) at the substantially middle part of the horizontal seal (b) by the horizontal cutting device (13), it becomes a individually wrapped pouch with each side sealed on four sides. A vertical cutting slit separating blade (14) to be inserted into the cutting part (c) by the slitter device (11) (12) is provided between the slitters (11) (12) and the horizontal cutting device (13), The separating blade (14) protrudes from the shaft (15) as seen from the side so that the composite paper cut in the above is not fused again.

In the present invention, in addition to the separating blade (14) as described above, distribution step rolls (16) and (17) are provided directly above the transverse cutting device (13). Each of the step rollers (16) and (17) is composed of a large diameter portion (18) and a small diameter portion (19) as shown in FIG. That of the step roller (17) corresponding to the diameter portion (18) is the small diameter portion (19), and that of the step roller (17) corresponding to the small diameter portion (19) of one step roller (16) is the large diameter portion (19). 18) are staggered. Therefore, the vertically long composite paper that has been vertically separated is distributed before and after by the distribution step rollers (16) and (17). In FIG. 2, the slitters (11) and (12) have a rotary shaft (21) next to which the projection (20) for inserting the notch (e) shown in FIG. A rotary shaft (23) having a saw blade (22) is provided below (21) so that perforations (f) can be inserted in the composite paper as shown in FIG.

In any case, the vertically long composite paper, which is separated right and left by the separation blade (14), is moved forward and backward by the large diameter portion (18) and the small diameter portion (19) of the distribution step rollers (16) (17). And falls toward a chute (24) installed below the transverse cutting device (13). A plurality of drop chutes (24) arranged in a row as shown in FIG. 7 was modified, and a plurality of drop chutes were partially overlapped and arranged in a zigzag pattern. According to FIG. 7, since the width of the cut surface of the slitter is very narrow, the lower end portion of the pouch rides on the upper end frame (24a) of the chute (24) and cannot be smoothly inserted inside. This plan is an improvement of this plan and the shoots are arranged in a staggered pattern. As shown in FIG. 3, the falling chutes have front chutes (25) and back chutes (26) alternately arranged, and the chutes are partially overlapped to form a zigzag shape in plan view.

The front chute (25) and the back chute (26) are inclined so that the front chute (25) and the back chute (26) cross each other in the upper part in a side view, and the inclined portion is connected to each other by the stay (27) as shown in FIG. ing. Each chute has a box shape, and one side surface (25a) (26a) is vertical and the other side surface (25b) (26b) is wide at the top and narrow at the bottom. The front chute (25) has an upright guide plate (28) on the upper front surface thereof, and the rearward inclined guide plate (29) on the upper rear surface thereof. A guide plate (30) inclined forward is provided on the upper front surface of the inner chute (26), and an upright guide plate (31) is provided on the upper rear surface. Therefore, the pouches that have been cut by the transverse cutting device (13) and sorted to the front and back by the sorting step rollers (16) (17) are guided by the guide plates (28) (29) in the front chute (25). , Is guided into the front chute (25) and is guided by the guide plates (30) and (31) in the back chute (26) to be guided into the back chute (26) and the pouch hits the upper end frame of the chute and is inserted. There is no reason not to be. Therefore, there is no line trouble and the product smoothly drops toward the conveyor (32), and 5 to 10 small bags are packed in cartons by the cartoning machine.

As described above, in the case of the present invention, after cutting by the slitter device (11) (12), it is separated by the vertical cutting slit separating blade (14). Since the composite paper is sorted back and forth by the sorting step rollers (16) (17) without fusing, the pouches cut by the transverse cutting device (13) are smoothly made into staggered drop chutes. It is distributed and inserted so that line trouble does not occur. If the perforation cutter (22) and the horizontal cutting device (13) are operated on every other horizontal seal (b), two pouches connected at the perforations are obtained as shown in FIG. The notch roller (20) and the perforated cutter (22) are omitted as necessary. In any case, the design can be changed arbitrarily within the spirit of the present invention.
