Description

  The present invention relates to a vertical multi-row filling and packaging machine used for manufacturing stick-type packaging bags.

  Conventionally, what was described in patent document 1 is known as an example of the vertical type multi-row filling packaging machine for stick type packaging bags manufacture. In this product, a raw material wrapping film is cut by a slitter by a predetermined width, each wrapping wrapping film is wound in a width direction by a former, and a cylindrical body is formed by applying a vertical seal to a stacked end by a vertical seal device. After a horizontal seal is applied to a predetermined position of the cylindrical body with a horizontal seal device, the powdered and granular contents are filled to form a semi-packaging bag, and the semi-packaging bag is sent out one cycle at a time. Further, a stick-type packaging bag is formed by applying a horizontal seal, and the horizontal seal portion is cut by a cutter device to manufacture a single packaging bag. In such a packaging machine, although it depends on the size of the stick, for example, a spreader having a width of about 900 to 1000 mm and set to about 10 rows can be said to be a popular machine.

Even in this type of packaging machine, it is gradually required to increase the production efficiency, and as one of the wings, an original fabric packaging film having a width of, for example, about 1200 mm, which is wider than the conventional one, is also available on the market. It became so.

However, if the lateral seal device becomes longer, for example, bending rigidity tends to be inferior, and bending occurs when it is attached to the aircraft, resulting in variations in the clamping force of the lateral seal portion, which leads to product quality degradation. There is a fear. In addition, if the lateral seal device is enlarged, it will be difficult to manufacture the lateral seal device, and it is necessary to remove the large and heavy lateral seal device for maintenance such as cleaning and inspection. It will be a place to have a number of problems such as taking time and effort.
Such a problem also occurs in the vertical sealing device, the cutter device, and the like.
The present invention has been completed on the basis of the above circumstances, and its purpose is to maintain the product in high quality and ensure handling while ensuring that the packaging bags are manufactured in multiple rows. Is to provide a packaging machine with improved convenience.

  The vertical multi-row filling and packaging machine according to the present invention is configured to divide and cut the raw fabric wrapping film fed out from the packaging material roll in the width direction, and distribute each cut cut film at a predetermined interval. A sorting device for feeding, and a slitter device for cutting the divided film into a plurality of strips, a former device for winding a plurality of divided packaging films into a cylindrical shape, and packaging by a feeding device A vertical seal device and a horizontal seal device that synchronously perform vertical seal and horizontal seal on a cylindrical packaging film that is intermittently fed one bag at a time, and a predetermined amount of content in each sealing bag that is sealed A packaging bag forming mechanism section in which a filling device for filling a product and a cutter device for cutting the packaging bag filled with the contents at the lateral seal portion to form a packaging bag, are arranged in a vertical direction. Between left and right Characterized in place it is juxtaposed two sets to open the.

According to the above configuration, the original packaging film fed out from the packaging material roll is cut by the cutting device and divided in the width direction, and each of the cut divided films is distributed at a predetermined interval by the distribution device. Each is introduced into the packaging bag forming mechanism part, while the divided film is fed to the left and right packaging bag forming mechanism parts, stick-shaped packaging bags are continuously manufactured over a plurality of rows respectively defined, Packaging bags are manufactured all at once over the left and right sides.
Briefly, when manufacturing a packaging bag using a wide packaging film in a predetermined multi-row, the packaging bag forming mechanism is divided into left and right parts, while the original packaging film is half-width or substantially half-width. The packaging bags are manufactured in such a manner that each packaging bag forming mechanism section manufactures a packaging bag over a predetermined half or approximately half of each film, and the mechanism sections together with a predetermined number. Manufacture over rows.

  Since the packaging bag forming mechanism section is divided into right and left parts, it is possible to keep the devices constituting the devices such as the horizontal seal device, the vertical seal device, and the cutter device arranged in the mechanism portion short. it can. Therefore, it is possible to ensure the bending rigidity of each device or component and prevent the occurrence of bending, etc., and to maintain the pinching force and the cutting position of the seal portion with high accuracy without variation, thereby preventing the quality of the product from deteriorating. In addition, the size of each device or constituent member simplifies the manufacturing itself and simplifies the detaching operation for maintenance and the like.

The following configuration may also be used.

The guide member is disposed at a predetermined interval in the feeding direction of the packaging film, and the cut packaging film is on the near side in the feeding direction with respect to the guide member on the near side in the feeding direction. After being looped over, it is looped over the guide member on the front side in the feeding direction so as to be folded back on the front side in the feeding direction.

  In the sorting apparatus, when the original fabric wrapping film cut in the width direction is hung on the guide member on the front side in the feeding direction and folded back, the cut left and right divided films have a predetermined angle. The left and right divided films thus cut and opened are then hung on the back guide member and turned back to the front side again. The paper is fed to the front side in the feeding direction with a predetermined interval corresponding to the above and taking a parallel posture. Here, the interval between the left and right divided films can be arbitrarily set by adjusting the inclination angle of the guide bar in both guide members, the interval between both guide members, and the like.

(2) The guide member is formed by arranging the left and right guide bars so as to form a V shape having a predetermined apex angle. The divided film can be distributed within a relatively small distance range in the feeding direction of the packaging film.
(3) The guide bar of the both guide members is rounded at the portion where the packaging film is hung. The slippage of the film is improved, and the feeding posture and interval of the divided divided film can be reliably maintained by a regular one.

  (4) In the lateral seal device, a pair of front and rear lateral seal blocks are provided in the base frame so as to be movable in the approaching / separating direction, and a plurality of rows of films formed in a cylindrical shape by being vertically sealed. By sandwiching a predetermined position between both horizontal seal blocks, horizontal seals are applied to the films in each row at the same time, and the inner ends of each base frame in the left and right horizontal seal devices are Connected by connecting parts, vertical slide shafts are inserted into the outer ends of both base frames and the connecting parts, respectively, so that the left and right horizontal seal devices can be moved up and down integrally along the slide shafts It is equipped and is configured to reciprocate up and down with a constant stroke.

  In the horizontal seal device, when the horizontal seal device is at the upper end position of the stroke, the horizontal seal is formed at the same time by sandwiching the predetermined positions of the film in each row formed into a cylindrical shape by the vertical seal between both horizontal seal blocks. The film is pulled downward by one bag after the horizontal seal device is lowered to the lower end position of the stroke with the horizontal seal applied, and then the two horizontal seal blocks are separated from each other. To return to the upper end position, and the above-described operation is repeated. Since the horizontal sealing device also serves as a feeding device, the structure is further simplified.

  (5) The vertical seal device is opposed to a fixed-side vertical seal portion in which a plurality of cylindrical seal portions are formed in a form in which the film is bent into a cylindrical shape and the ends are overlapped, The cylindrical seal portion has a structure in which the same number of vertical seal blocks that are driven back and forth toward the portion that receives the overlapping portion of the film are arranged side by side so that the movable side vertical seal portion can be opened and closed, and left and right vertical seal devices In each case, each movable-side vertical seal portion can be opened and closed in a double door manner.

  In the vertical sealing device, in the cylindrical sealing part, each film is formed into a shape that is turned into a cylindrical shape and the ends overlap each other, and the opposing vertical sealing block advances to press the overlapping part. A vertical seal is applied. When performing maintenance such as cleaning, it is easy to work because the inside is opened by opening the movable side vertical seal part without removing it one by one. In particular, each movable side vertical seal part can be shortened, so the shaft part Therefore, it is possible to avoid the occurrence of twisting or the like and to smoothly open and close. Further, the movable side vertical seal portions of the left and right vertical seal devices can be opened in a double-spread manner, and the opposite surfaces of both the vertical seal portions can be fully opened toward the front side, making maintenance work extremely easy.
