チ包装機。 A packaging object holding device 6 includes a rotary table 2 on which an object to be packaged 5 is placed, a presser plate 7 that presses the upper surface of the object to be packaged on the rotary table, and a lifting arm 8 that supports the presser plate. In a stretch packaging machine, the main body is a film winding mechanism 4 which arranges a film roll 3 perpendicular to the rotary table and holds the film roll so as to be able to unwind it. Arm 8 and Tsuba 13
It has a cylindrical body 13 with a and a flange 14a that engages with the flange 13a, and is connected by an engaging element 12 that is made up of a weight-shaped body 14 that is slidably fitted on the inner periphery of the flange 13a and the bottom thereof. At the same time, the presser plate 7 presses the object to be packaged 5.
The presser plate 7 is in contact with the upper surface of the article 5, and is provided between the inner periphery of the collar 13a of the cylindrical body 13 and the tapered part of the cone-shaped body 14, and is tiltable along the upper surface of the article 5. The lifting arm 8 is moved to a position where there is a sufficient distance t to allow rotation of the package around the axis of rotation of the package.
A stretch packaging machine characterized by comprising a detection device 9 that detects that the lifting arm is lowered and stops the lifting arm.
