Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packing band mounting machine mainly provided in an automatic packing machine.
[0002]
[Prior art]
A packing band of an automatic packing machine or the like is usually wound around a paper tube having an inner diameter of 200 mm, and the paper tube is discarded after use.
[0003]
[Problems to be solved by the invention]
The packing band is a paper tubeless band that does not use a paper tube, thereby saving material and reducing waste.
[0004]
[Means for Solving the Problems]
This will be described with reference to the drawings. In the paper tubeless band mounting jig according to the present invention, the fixing flange 30 is fitted and fixed to the horizontal main shaft 20, and the fixing plate 40 is fitted and fixed adjacent to the fixing flange 30. The base end of at least three X links 60 radially arranged at equal angular intervals is connected to a slide plate 50 that has been slidably fitted and supported via a support shaft 61. The two ends of 60 are connected via pins 74 to the back surface of an arc plate 70 on which the paper tubeless band 17 is mounted, and a coil spring 56 is disposed on the sliding plate 50 to slide with the sliding pressing plate 55. The flange 35 and the main shaft 20 are slidably fitted and supported on the main shaft 20, and a fastening nut 36 for moving the sliding pressing plate 55 and the sliding flange 35 forward and backward is screwed to the outside of the sliding flange 35. , Sliding with 70 arc plates It is obtained by forming a reel 16 by the flange 35.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
A band mounting machine 15 is attached to a side surface of an automatic packing machine 12 where a band-shaped band is wound around a work 13 transported into an arch 11 on a table 10. The present invention is a jig for a band mounting machine 15 suitable for a paper tubeless band without a paper tube.
[0006]
A fixing flange 30 is fitted and fixed to the horizontal main shaft 20. A fixing plate 40 is fitted to the main shaft 20 adjacent to the fixing flange 30, and the fixing plate 40 includes a lock mechanism 24 composed of an inner ring 25 with a cut 25a, an outer ring 26 with a cut 26b, a spacer 27, and a tightening bolt 28. To the main shaft 20. A sliding plate 50 is slidably fitted to the main shaft 20. The plurality of guide rods 51 of the sliding board 50 are slidably inserted into the plurality of guide holes 41 of the fixed board 40. The base ends of at least three radially displaceable X-links 60 arranged at equal angular intervals are connected to the fixed board 40 and the sliding board 50 via a support shaft 61. The X link 60 has two links pivotally connected by a pivot 62 so as to be able to change its angle.
[0007]
The two ends of the X-link 60 are connected to the radially elongated holes 72 and the generatically elongated holes 73 of the rearwardly projecting strip 71 of the arc plate 70 via pins 74, respectively. A coil spring 56 is disposed on the sliding plate 50, and a sliding pressing plate 55 is slidably fitted and supported on the main shaft 20. A tension bolt 57 penetrating the coil spring 56 is inserted into the through hole 52 of the sliding plate 50 and is erected on the sliding pressing plate 55. A sliding flange 35 is slidably fitted and supported on a portion of the main shaft 20 outside the sliding pressing plate 55. A tightening nut 36 is screwed into a portion of the main shaft 20 outside the sliding flange 35, and the tightening nut 36 moves the sliding flange 35 forward and backward. The reel 16 is constituted by the fixing flange 30, the group of at least three arc plates 70, and the sliding flange 35.
[0008]
In the state shown in FIG. 5, the fastening nut 36 is removed as shown in FIG. 3, and the sliding flange 35 is removed from the main shaft 20. When the group of arc plates 70 is manually reduced in diameter as shown in FIGS. 9 to 7 as necessary, the sliding plate 50 moves outward (to the right in FIGS. 3 to 7 and FIG. 9) via the X-link 60. . As shown in FIGS. 3 and 4, the paper tubeless band 17 is fitted to the outside of the group of arc plates 70 (the state shown in FIGS. 7 and 8). When the sliding flange 35 is fitted on the main shaft 20 and the tightening nut 36 is tightened, the paper tubeless band 17 is held by the reel 16 constituted by the fixing flange 30, the group of arc plates 70, and the sliding flange 35 (FIG. 6, FIG. 9 and FIG. 10).
[0009]
【The invention's effect】
Since the paper core can be omitted from the packing band, it is possible to save material and reduce waste.
