Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a horizontal pillow packaging device, and more specifically, a bag making device that forms a packaging film drawn from a roll of material into a cylindrical shape. , a supply means for sequentially feeding the items to be packaged onto the film in the bag-making device, a vertical sealing means for continuously heat-sealing both side edges of the cylindrical film;
This relates to a horizontal pillow packaging device comprising a conveyor means for conveying the packaged object housed in a cylindrical film together with the film, and a lateral sealing means for heat-sealing and cutting the cylindrical film at both end edges of the packaged object. be.

(Prior art) Horizontal pillow packaging devices are extremely widely used for packaging various products, but in the case of products that easily generate noodle scraps during transportation and packaging, such as instant noodles, this moves within the cylindrical film, and if you do not leave enough space between the items to be packaged, the noodle scraps will get caught in this seal when sealing and cutting between the two, making it impossible to obtain an airtight seal. This can lead to defective packaging that cannot be handled properly. Therefore, in conventional horizontal pillow packaging devices for packaging items that tend to generate noodle scraps, such as instant noodles, the length of the bag is set to be more than sufficient for the item to be packaged, resulting in high packaging material costs. Not only that, but the appearance after packaging was also not good.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned conventional problems.The purpose of the present invention is to improve the bag length of products that tend to generate noodle scraps, such as instant noodles. To provide a horizontal pillow packaging device capable of packaging reliably and with good appearance.

(Means for Solving the Problems) In order to achieve the above object, the horizontal pillow packaging device according to the present invention uses a cylindrical shape as a conveyor means for conveying the packaged items housed in a cylindrical film. Supporting members for supporting the lower side of the film are arranged at predetermined pitches with required spacing in the front and back, a swinging piece is pivotally connected to the conveyor means between the receiving members, and a horizontal bar is attached to the swinging piece, An elastic means is provided for biasing the swinging piece to one side so that the horizontal bar is always positioned below the receiving member, and a cam means on which the swinging piece can slide is provided adjacent to the conveyor means, so that the swinging When the piece comes into contact with the cam means as the conveyor means runs, it swings up and down against the elastic means, and the horizontal bar attached to the swinging piece moves up and down to move the cylinder between the wrapped objects. The lower film of the packaging film formed in the shape is pushed up from below to the top in a chevron shape, so that there are no noodle scraps etc. on the film between the front and back adjacent items to be packaged. This makes it possible to ensure subsequent lateral sealing even if the interval between them is narrowed.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The figure shows an instant noodle 1 shaped like a rectangular parallelepiped.
The horizontal pillow packaging device of the present invention is applied to packaging ramen noodles, and the noodles of this ramen 1 are extremely brittle, and some of them may fall off as noodle scraps during transportation for packaging. Occurs from time to time.

In this horizontal pillow packaging device, a roll of packaging film 2 (not shown) is rotatably supported at the lower part of the machine frame.
From here, the film 2 is pulled upward and guided through the guide rollers 3 to the bag making machine 4. In this bag making machine 4, the film 2 is formed into a cylindrical shape, and its both side edges are aligned in the shape of palms together at the center of the upper part. A supply conveyor 5 for instant noodles 1 is provided behind the bag making device 4 in the traveling direction.
Instant noodles 1 are placed on this conveyor 5 at predetermined intervals, and are sequentially sent forward by a pushing claw 6 at the rear thereof. The ramen 1 is fed from the front end of the conveyor 5 into the rear end opening of the bag making machine 4, and then accommodated inside the cylindrical film 2 and transported forward together with the film 2.

A pair of heat-sealing rollers 7-7 are disposed in front of the bag-making device 4, sandwiching the edges of the film 2 that are joined together in a palm-shaped manner, thereby heat-sealing the edges of the film 2. When it passes between the rollers 7-7, this edge is heat-sealed and becomes cylindrical.

Furthermore, a conveyor means is provided in front of the bag making machine 4. This conveyor means is mainly composed of a pair of left and right endless chains 8-8 and a concave receiving frame 9 disposed between the two endless chains 8-8. This concave receiving frame 9 has a small width so that it can be attached to each chain unit so that it does not interfere with the rotation of the chain around the sprocket. Since this concave receiving frame 9 has a small width, a sufficient number of the concave receiving frames 9 are arranged in parallel along the longitudinal direction of the endless chain 8-8 to receive the objects 1 to be packaged. The groups are provided so as to match the predetermined packaging size intervals of the instant noodles 1, which are the packaged items.

The above endless chain 8-8 runs on the supply conveyor 5.
The timing is adjusted to match the supply of instant noodles 1 by the bag making device 4, and when the instant noodles 1 that have passed through the bag making machine 4 reach between both endless chains 8-8, they are received by the group of concave receiving frames 9.・Between the groups of the concave receiving frames 9, the bases of the abbreviated swinging pieces 10-10 are pivotally connected to a pair of left and right endless chains 8-8 by pivot pins 11-11, respectively. has been done. A fixed pin 12 is installed at the upper end of each swing piece 10, and a tension spring 14 is interposed between the fixed pin 12 and a chain pin 13 adjacent to the pivot pin 11 in the rear direction. has been done. Further, a roller 15 is pivotally supported at the rear lower end of each rocking piece 10 in the traveling direction, while a horizontal bar 16 having a circular cross section is provided across the rear upper end of the rocking piece 10-10 facing left and right. .

As mentioned above, a support plate 17 is provided below the running path of the swinging piece 10-10 attached to the endless chain 8-8.
A plurality of chevron-shaped cam plates 18-18 are attached at predetermined intervals on -17, and the roller 1 attached to the rear lower end of the swinging piece 10-10 is attached as the endless chain 8-8 runs.
5-15 can rise above this cam plate 18-18.

When the instant noodles 1 are received on the concave receiving frame 9 at the rear end side in the direction of movement of the endless chain 8-8, that is, near the bag making device 4, the swinging piece 10-10 at the rear thereof is still attached to the cam plate 18-. 18, as shown in FIGS. 2 and 3, the tension of the springs 14-14 causes the shape to be tilted backwards, and the horizontal bar 1
6 is located below the receiving frame 9. When the chain 8-8 travels and approaches the upper part of the cam plate 18-18, as shown in FIGS.
18, the 1-shaped swinging piece 10-10 resists the tension of the spring 14-14 and moves to the pivot pin 11-11.
Rotate forward around the center and stand up. As a result, the horizontal bar 16 extending between the rear upper ends of the photographing pieces 10-10 moves above the concave receiving frame 9 and lifts the packaging film 2 upward from below in a chevron-shaped manner. If there are noodle scraps between the concave receiving frame group, they are collected on the front or rear side of the instant ramen block. When the above-mentioned rocking piece 10-10 passes the cam plate 18-18, it is in an inclined state as shown in FIG. 2 until it reaches the next cam plate, and the horizontal bar 16 is positioned below the concave receiving frame 9. I come to do it.

In the illustrated embodiment of the present invention, the cam plates 18 are arranged in four stages on the running path of the endless chain 8.
Since the lower side of the packaging film 2 is pushed up four times in a mountain shape by the horizontal bar 16, all the noodle scraps located between the film vibrations are completely collected on the front and rear instant noodle blocks. It will be done.

A top and bottom sealer 19 is provided in front of the final stage cam plate 18.
a, 19b are provided, and these upper and lower sealers 19a, 1
A cutting blade 20 and a receiving blade 21 are provided in the center of the shoe 9b. These upper and lower sealers 19a and 19b seal the packaging film in the middle part of the adjacent concave receiving frame group in a wide width, and cut the center of this sealed part.
An instant noodle package 22 is obtained by cutting off the rear film.

In the above embodiment of the present invention, the cam plates 18 are arranged in four stages in the running direction of the endless chain 8, but it is not necessarily necessary to provide them in multiple stages.

Further, it goes without saying that the shape of the cam plate 18 can be changed as appropriate other than the illustrated example.

(Effects) As described above, according to the horizontal pie packaging device according to the present invention,
Since the lower part of the film between the front and back packaged items that are transferred at a predetermined interval within the cylindrical film is pushed up in a mountain shape, the noodle scraps, etc. that are present in between can slide down the film surface forward or backward. If the packaged items include waste, etc., these items are fed into the film one after another at relatively narrow intervals.
Since the film parts near the front and rear ends of the packaged object can be sealed and cut, it is possible to reduce packaging material costs and improve packaging efficiency, and it is also possible to package the packaged items relatively tightly. A good-looking package can be obtained.
