することはない。 A packaging film in which packages to be separated are continuously formed is cut out by a die 21 of a punching device 2 and a punch 2.
3, and when the packaging body reaches a predetermined position with respect to the die 21 and the punch 23, the feeding of the packaging film f is stopped. After that, the punch 23 is raised together with the movable table and pushed into the punched hole 22 to separate the parts between the packages to be separated. A slit S as shown in FIG. 5 is punched out along the line. This slit S
are two rows of horizontal punch lines 51 extending in the width direction of the packaging film f and spaced apart by a predetermined distance in the longitudinal direction.
, arc-shaped corner punch lines 52 connected to each of the horizontal punch lines 51 and defining the corners of the separated package, and corner punch lines 52 at both end portions.
It has a shape formed by vertical punching lines 53 that interconnect each other. In this state, the slits are simply formed at predetermined intervals in the longitudinal direction of the packaging film, so the packaging body does not separate from the packaging film.

により包装体は分離する。 Next, when the packaging film f is sent to the position of the cutter device 3, the rotating cutter blade 32 and the cutter receiver 33 move the packaging film f along the side edges of the package extending in the longitudinal direction and at each corner. A cut is made at the cut l 3 connecting with the punch line 52, whereby the package is separated.

い。 At this time, set the radius of curvature of the corner of the punch in advance so that even if the cutter blade shifts slightly in the width direction due to shrinkage of the film, the cutting line will be within the range of the arcuate punching line of the corner of the separated package. If this is done, sharp edges will not form at the corners of the package.
分離された包装体はカツタ受け３３上に乗つた
状態で包装フイルムに押されて次の工程に送られ
る。 The separated package is placed on the cutter receiver 33 and is pushed by a packaging film and sent to the next process.
(ヘ) 効果
本発明の分離装置によれば次のような効果を奏
することができる。(F) Effects According to the separation device of the present invention, the following effects can be achieved.
打抜き装置のダイを上側にかつパンチを下側
に設けて包装体の一部分を打ち抜くだけなので
包装体を落下させるおそれはなく、パンチの幅
を２mm程度まで薄くできるのでその分包装体間
の間隔がせばめられスクラツプを少なくでき
る。 The die of the punching device is placed on the top and the punch is placed on the bottom to punch out a portion of the package, so there is no risk of the package falling.The width of the punch can be made as thin as 2 mm, so the gap between the packages can be reduced accordingly. It is narrowed and reduces scrap.
打抜き装置で一度に打ち抜いた場合打抜き時

ているので箱詰等の自動化が可能となる。 When punching is done all at once using a punching device, in order to pack the packages in the next process while maintaining the arrangement of the packages at the time of punching, the packages are held by suction after punching and transferred in an aligned state onto a conveyor supported by flanges. However, in the present invention, by sending the packages onto the chute with the flanges supported after separation, the packages are aligned without falling apart, making it possible to automate packaging, etc. It becomes possible.
