れる。As shown in FIG. 14, this film packaging machine has a feed conveyor shaft 102a 'for driving a feed conveyor 102a to which an attachment 101 for feeding the article to be wrapped 100 is attached, horizontal sealers 103, 103', and vertical sealers. Reference numeral 104 is a motor 107, a transmission 108, and a speed reducer 1.
13, electromagnetic clutch / brake unit 111, shaft 10
5 is driven. A cam 119 for turning on / off the limit switch 120 is attached to the shaft 105. The to-be-packaged object 100 is covered by the film 109 in the film 115, and the vertical sealer 104 is welded to perform vertical sealing to form a tubular film.
Auxiliary conveyor 117, 117a driven by 02 '
Auxiliary conveyer is used to form a three-way seal bag for each bag length having a predetermined width according to the longitudinal dimension of the object to be packaged 100 by welding and fusing the horizontal sealers 103, 103 ′, and the delivery conveyor shaft 11
It is unloaded from the delivery conveyor 114 driven by 4 '.

よって常に正常に搬送できないという難点がある。In such a film packaging machine, the feeding speed of the feed conveyor 102a is made higher than the feeding speed of the film 115, and the article 100 to be packed is extruded and fed by the attachment 101, and is fed from the feed conveyor 102a. Handed over to the Foma 109. However, depending on the nature and type of the object to be packaged 100, particularly in the case of difficult-to-carry items such as soft items such as Japanese and Western confectioneries and loose items such as vegetables, the speed difference between the two may cause the transfer from the supply conveyor 102a to the former 109. However, there is a problem in that it cannot always be conveyed normally due to friction.

Must be an integral multiple of the vertical dimension of 00. Therefore, when the vertical dimension of the article to be packaged 100 is to be changed, the formula 1 should be satisfied so that this integral multiple relationship is satisfied.
It is necessary to change the position of 09 and replace it with the supply conveyor 102a to which the attachment 101 corresponding to the vertical dimension of the article to be packaged 100 is attached. There is a problem that such a position change and a conveyor exchange require extremely complicated work. Moreover, even when the vertical dimension of the packaging bag is changed, the horizontal sealers 103 and 103 'must be welded and fused at an intermediate position between the packaging bag lengths to form a packaging bag of a predetermined width. It is extremely troublesome to position the horizontal sealers 103 and 103 'by welding at the intermediate position between the bag length and the bag length.
