Abstract

PROBLEM TO BE SOLVED: To eliminate a paper sleeve from a packaging band to save the materials and reduce the waste. SOLUTION: A first flange 30 is fitted and fixed to a horizontal main spindle 20, and the base ends of X links 60 arranged at equal angle intervals are connected to a first cam board 40 fitted and fixed adjacently to the first flange 30 and a second cam board 40 slidably fitted and supported to the main spindle 20 through support shafts 61. Each tip of the X links 60 is connected to the reverse side of a circular plate 70 through pins 74, respectively. A pressing plate 55 is slidably fitted and supported to the second cam board 50 through a coil spring 56, and a fastening nut 36 for protruding and recessing a second flange 35 fitted to the axial outside of the pressing plate 55 is screwed to the main spindle 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing band mounting machine mainly provided in an automatic packing machine.

[0002]

2. Description of the Related 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]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the amount of material and the amount of waste by using a paper band-less band in which a paper band is not used as a packing band.

[0004]

A description will be given with reference to the drawings. The paper tube-less band mounting jig according to the present invention includes: a first cam disc 40 having a first flange 30 fitted and fixed to the horizontal main shaft 20 and being fitted and fixed adjacent to the first flange 30; The base end of at least three X-links 60 radially arranged at equal angular intervals is connected to a second cam disc 50 which is slidably fitted to and supported by a support shaft 61. The two ends of the X-link 60 are connected to the back surface of the arc-shaped plate 70 via pins 74, respectively. A coil spring 56 is arranged on the second cam disc 50 to connect the pressing plate 55 and the second flange 35 to the main shaft 20. And a pressing plate 55 is provided on the outside of the second flange 35.
A tightening nut 36 for advancing and retracting the second flange 35 and the second flange 35 is screwed together, and the reel 16 is formed by the first flange 30, the group of arc plates 70 and the second flange 35.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A band mounting machine 15 is attached to a side of an automatic packing machine 12 where a band-shaped band is wound around a work 13 conveyed 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.

A first flange 30 is fitted and fixed to the horizontal spindle 20, and an inner ring 25 with a cut 25a and an outer ring 26 with a cut 26b are adjacent to the first flange 30.
And a first cam disc 40 fitted and fixed via a lock mechanism 24 constituted by a lock mechanism 24 constituted by a bolt 27, a spacer 27 and a fastening bolt 28. The second cam disc 50 having the guide rods 51 slidably inserted into the plurality of guide holes 41 of the cam disc 40 is radially arranged at least three equal intervals including the main shaft 20. Deflected X-link 60
Are connected via a support shaft 61. X link 6
In the case of 0, two links are pivotally connected by a pivot 62 so as to be able to change its angle.

Each of the two ends of the X-link 60 has an arc plate 70
The pin is connected to the elongated hole 72 in the radial direction and the elongated hole 73 in the generatrix direction of the back-side bushing ridge 71, respectively.
A coil spring 56 is disposed on the cam disk 50, and the pressing plate 55 and the second flange 35 are slidably fitted and supported on the main shaft 20, and a tension bolt 57 penetrating the coil spring 56 is inserted into the through hole 52 of the second cam disk 50. The second flange 35 is slidably fitted to and supported on the main shaft 20 outside the pressing plate 55, and the second flange 35 is advanced and retracted outside the second flange 35. The nut 36 is screwed into the first flange 30 and at least three arc plates 7.
The reel 16 is constituted by the group 0 and the second flange 35.

[0008] The tightening nut 36 is removed, and the second flange 35 is removed.
From the main shaft 20. When the group of arc plates 70 is manually reduced in diameter as needed, the second cam plate 50
Moves outward. The paper tubeless band 17 is fitted outside the group of arc plates 70. When the second flange 35 is fitted on the main shaft 20 and the fitting nut 36 is tightened, the paper tubeless band 17 is held by the reel 16 constituted by the first flange 30, the group of arc plates 70, and the second flange 35.

[0009]

[Effect of the Invention] Since the paper tube can be omitted from the packing band, it is possible to save material and reduce waste.
