Description

  The present invention relates to a method and an apparatus for mounting a sachet enclosing a desiccant or the like inside a sachet containing a packaged item.

    In the case of a bag making filling and packaging device, each of the sachets is subjected to a process of making and sealing the belt-like film around the package after the sachets are attached to the belt-like film before bag making at equal intervals. Is firmly fixed to each package. On the other hand, in the case of a bag-packing and packing apparatus that fills a packaged product with a package that has been completed in advance, the work of attaching each small bag inside each package increases the number of work steps. Inefficient.

  Therefore, in the following Patent Document 1, a small bag is put into an empty bag in one step. In step 2, the permanent magnet is brought close to the empty bag, and a magnetic bag containing iron oxide is adhered to the inner surface of one side of the empty bag. A technique is disclosed in which the empty bag is filled with an object to be packaged in step 3, and the sachet is fixed to the inner surface of the wrapping bag according to the bulkiness and gravity of the object to be packaged.

  Further, in Patent Document 2 below, a partition is provided in a hopper for filling a packaged article, and a passage for passing a sachet and a path for passing a package are formed across the partition, and the sachet and the packaged article are formed. Is simultaneously fixed to the inner surface of the wrapping bag on the predetermined side with the bulk and weight of the packaged item.

  However, none of these techniques has a problem that the sachet is mixed with food to be cooked away from the sachet when the sachet is not fixed to the sachet and the packaged food is food that needs cooking.

Japanese Patent Laid-Open No. 62-158601 JP 2005-343490 A

  In view of the above-described problems, the present invention aims to attach a small bag to a sachet without going through an extra step, and sandwiches both side edges by a plurality of pairs of clamping claws. Each wrapping bag suspended and suspended is intermittently transferred in a column shape, and each wrapping bag that reaches the first station in the tandem transfer track is sequentially filled with the objects to be packaged, and then each wrapping bag is transferred to the second station. In a rotary bag filling and packaging apparatus in which the opening edge of the bag is welded with the pressure of the heat seal bar, a mounting section is set between the first and second stations, and the top of the bag reaching the mounting section. In the region, a sachet supply means for feeding the number of sachets in a relationship of 1 to the number of sachets, and a sachet fed by the sachet supply means with a clamper, and then the rotational movement of the clamper Means for inserting the sachet into a V-shaped gap on one side of the opening of the wrapping bag in a wedge-like manner, and with the clamping pressure by the heating seal bar on the wrapping bag opening edge in the second station, The upper edge is configured to be integrally welded to the opening edge of the bag.

  The present invention carries a sachet held by a clamper into the opening portion of the sachet by the rotational movement of the clamper, and also uses the rotational energy to connect the side edge of the sachet to the V-shaped gap inside the opening portion of the sachet. It is characterized in that it is inserted in a wedge shape. In other words, if the rotation speed of the clamper is set to be higher than the transfer speed of the wrapping bag, the sachet can be attached to the wrapping bag so as to track the wrapping bag being transferred without stopping at the mounting section. It is highly efficient. Even if it is set to stop the wrapping bag in the mounting section, it is efficient because the sachet is inserted in a wedge shape inside the wrapping bag using the rotational movement of the clamper, and then the wrapping is performed with the pressure of the heating seal bar. A sachet can be attached to the bag.

  In addition, when welding the opening edge of the wrapping bag with the clamping pressure of the heating seal bar, an operation of tensioning the opening edge by separating the pair of holding claws is required. The side edge and the upper edge of the sachet until the opening edge of the sachet is welded by the pressure of the heat seal bar by synchronizing with the operation of inserting the sachet in a wedge shape in the V-shaped gap inside the opening of the bag The two sides of the bag can be sandwiched between wrapping bags to improve the frequency of child bag dropout

  FIG. 1 shows a part of a rotary type bag filling and packaging apparatus. In this apparatus, a plurality of pairs of clamping claws 11 that are a pair are supported by an endless chain or a disk, etc., and each pair of clamping claws 11 clamps both side edges of the wrapping bag 10 and suspends them. The power of the disk is configured to intermittently transfer each packing bag 10 by one pitch along a column transfer track 12 in the arrow direction. In addition, since this type of apparatus has widely known examples, detailed illustration of the entire structure is omitted.

  In the above apparatus, when the packaging bag 10 opened by the relative approach of the pair of clamping claws 11 reaches the first station A, the packaging material 13 is filled in the packaging bag 10 at the station, Thereafter, the wrapping bag 10 is transferred toward the mounting section B in the rear area. In this section, the wrapping bag 10 is not necessarily stopped, but in this embodiment, the wrapping bag 10 is described as being stopped in this section.

  In the upper area of the mounting section B, a transport guide 17 of a belt-like body 16 in which a large number of sachets 15 are continuous is disposed. A small bag supply means 18 is provided for feeding the sachets in the relationship of number 1.

  That is, as shown in FIG. 2, the belt-like body 16 composed of each sachet 15 supported by the reel 19 has a relationship of the number of sachets 1 to the number of sachets 1 with the intermittent rotational power of the pair of transport rollers 21. The conveying relationship is established, and the pair of cutters 22 is a system for cutting and separating one sachet 15 from the belt-like body 18 in accordance with the transfer pitch of the sachets 15.

  The clamp 20 supported by the shaft 23 in the mounting section B of FIG. 1 holds the sachet 15 separated from the belt-like body 16 in time with the cutting operation of the sachet 15, and the child with the rotational power of the shaft 22. The bag 15 is carried along the arrow 24 into the bag 10. In the drawing, the shaft 23 rotates in the clockwise direction, and the sachet 15 is carried from the outside to the inside of the wrapping bag 10 in the transfer direction of the wrapping bag 10.

  The illustrated wrapping bag 10 is a three-sided sealing bag in which the bottom edge 25 and both side edges 26 of each of two overlapped films are sealed with a predetermined width, and formed by overlapping two films as shown in FIG. A narrowed V-shaped gap 28 is formed inside one side of the wrapped bag. In short, the side edge of the pouch 15 is inserted into the gap in a wedge shape and supported. When the packaging bag reaches the second stop section (not shown) in the rear area of the mounting section B in the transfer direction of the packaging bag 10 in FIG. 1, the upper opening edge 27 of the packaging bag 10 is a pair of pairs as shown in FIG. It is welded 30 with the clamping pressure and heat by the seal bar. In this case, as a result of the upper edge 31 of the small bag 15 being clamped with the seal bar and integrally welded, the loading of the child bag into the package is completed.

  1, the sachet indicated by an imaginary line 15A is carried into the wrapping bag 10 and inserted in a wedge shape, so that the lightweight sachet is sufficiently supported by the wrapping bag 10 due to the friction of the wedge that enters the gap between the wrapping bags. Is done. However, there is a possibility that the sachet 15A may fall off due to an impact when the clamp 20 is pulled out from the inside of the sachet 10, so that the sachet 15 is held from the outside of the sachet 10 by the auxiliary clamp 32 in the mounting section B as shown in FIG. This state is maintained up to the second station, or alternatively, the work of separating the pair of holding claws 11 is synchronized with the work of carrying the bag 15A into the bag, and the bag 15A is moved by the tension of the bag opening edge. There are choices such as supporting.

  In FIG. 2, a forward / reverse motor 33 for operating the shaft 22 is supported by a base 34. The shaft 23 in FIG. 1 supported by the base 34 is controlled to be displaced in the directions of left and right 35, 36 and in the directions of up and down 37, 38, respectively. The movement adjustment of the shaft 23 to the left and right 35, 36 is mainly an adjustment when the lateral width of the bag 10 is changed. However, in the case where the small bag 15 is loaded into the moving package 10 without being stopped in the loading section B, the shaft 23 is moved in the left-hand direction 35 in accordance with the movement of the package 10. . On the other hand, the adjustment of the shaft 23 to the upper and lower sides 37 and 38 is for changing the overlapping width of the upper edge of the small bag 15 with the welding width 30 with respect to the opening edge of the bag.

  In FIG. 1, the clamp 20 rotates clockwise to carry the small bag 15 into the left hand of the wrapping bag 10, but in contrast to this, the clamp 20 is rotated counterclockwise and placed inside the right hand of the wrapping bag 10. It is also possible to carry in the pouch 15. In this case, in order to avoid the impact of the sachet 10 and the sachet 15, the shaft 23 is displaced in the left direction 35 and the impact is adjusted.

  FIG. 5 is a partial view of a flat bag 40 formed of a plastic tube. Compared with the wrapping bag 10 shown in FIG. Since a thin film is used, a V-shaped gap that supports the pouch 15 is not easily formed. For this reason, there exists a tendency for the wedge effect of the pouch 15 to be hard to be exhibited. Therefore, as shown in FIG. 6, the space between the opposing corners 43 of the fixed claw material 41 on one side forming the clamping claw 11 and the movable claw material 42 on the other side is cut into a V shape, and this corner is interposed via the flat bag 40. By inserting the sachet 15 in a wedge shape between 43, the sachet 15 can be supported in the flat bag 40.

  The packaging material forming the sachet 15 shown in FIG. 4 is fused with the sealing portion of the sachet 10 heated and melted by a seal bar by using, for example, a vinyl chloride-based material that is easily melted at a relatively low temperature. Easy to adhere. However, when the material for forming the small bag 15 is difficult to melt, a small hole 45 is formed in advance on the upper edge of the child bag 15 as shown in (1) of FIG. By melting the adhesive coated between the upper opening edges 17 of the wrapping bag 10, the child bag 15 can be attached to the wrapping bag. Alternatively, as shown in FIG. 7 (2), notches 46 are formed in advance on both side edges of the child bag 15, and the upper opening edge 17 of the bag 10 is sealed through the notches 46. The child bag 15 can be attached to the bag. The perforation 50 formed in the upper part of the wrapping bag 10 is a means by which the upper part of the wrapping bag can be opened while the sachet 15 is attached to the upper member of the wrapping bag by tearing this part.

Alternatively, one side film 46 of the sachet 15 formed by folding in half as shown in FIG. 8 is protruded above the other side film, and the adhesive coating surface 47 of the protruding film 46 is left bare. The child bag can be loaded into the inside of the wrapping bag by integrally welding this surface and the sealing surface of the wrapping bag.
