Detailed Description
Fig. 1 shows a perspective view of an intermittently operating stretch film wrapping machine 1 according to the present invention. The stretch film wrapping machine 1 has a forming station 2, a sealing station 3, a transverse cutting device 4, and a longitudinal cutting device 5, which are arranged in this order on a frame 6 in a conveying direction R. On the input side, a supply roll 7 is arranged on the machine frame 6, from which a carrier film 8 is drawn off. The stretch film wrapping machine 1 furthermore has a conveyor chain 11, which grips the carrier film 8, in particular a conveyor chain or gripper chain 11 arranged on both sides, and which conveys the carrier film 8 further in the conveying direction R in each main operating cycle.
In the embodiment shown, the shaping station 2 is designed as a stretching station, in which grooves are formed in the carrier film 8 by stretching, for example by means of compressed air and/or vacuum. The forming station 2 can be designed such that a plurality of recesses are formed next to one another in a direction perpendicular to the conveying direction R. After the shaping station 2 in the conveying direction R, a filling section 12 is provided, in which filling section 12 the recesses formed in the carrier film 8 are filled with the product.
The sealing station 3 has a sealably closed chamber 3a in which the atmosphere in the recess can be evacuated and/or replaced by a degassing by means of exchange gas or by means of a gas mixture, for example, before sealing by means of the upper film 10 output from the upper film receptacle 9.
The transverse cutting device 4 may be configured as a blanking machine which severs the bottom film 8 and the top film 10 between adjacent recesses in a direction transverse to the conveying direction R. The transverse cutting device 4 is operated in such a way that the carrier film 8 is not cut over the entire width, but at least in the edge regions.
The longitudinal cutting device 5 can be configured as a knife device, by means of which the base film 8 and the upper film 10 are cut off between adjacent recesses and at the side edges of the base film 8 in the conveying direction R, so that separated packages are present after the longitudinal cutting device 5.
The right and left conveying chains 11, 11 of the stretch film wrapping machine 1 that grasp the film 8 on both sides are respectively guided in chain guides 13. The chain guides 13 are each protected to the outside by a side wall 14 of the stretch film wrapping machine 1 and are optionally fastened to the side wall 14. The side dams 14 may be plate members.
