Each blade 12 connects to a movable body 27 of general scalene quadrilateral by means of a support shaft 18. The movable body 27 moves to centrifugally against the rotating carousel in radius direction and the blades 12 touch on a label 10 accommodated in the label magazine 9. Consequently, an easy withdrawal of the label 10 from the label magazine 9 is available.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label take-out device for taking out a label from a label magazine in a labeling machine.

[0002]

2. Description of the Prior Art Usually such a label take-out device has a rotating body, to which a label take-out mechanism known as a blade is attached. The blade has a curved active surface that contacts the adhesive and is covered with a thin layer of adhesive before passing through the label magazine. In the label magazine, the curved active surface of each blade pulls the label (without slipping) and the layer of adhesive removes the label. In the prior art, the size of the active surface of the blade is at least equal to the size of the label.

[0003]

The length referred to above is about 180 mm to 200 mm, and the standard size of the diameter of the rotating body is about 400 mm, so that the entire label take-out device can be used for the whole labeling machine. It is sized to be housed to limit mass. If larger labels were to be used, the size of the label ejector would also increase, leading to obvious economic and implementation drawbacks, i.e., other configurations of the labeling machine would increase in size and hence production and production. It will be more costly to carry, etc.

[0004]

The main object of the present invention is to:
It is to provide a standard size label ejector to eliminate the above mentioned drawbacks and to be able to eject labels larger than standard labels, in particular to allow labels much longer than the active surface length of conventional blades. .

Further, these and other objects include a label removing device for a labeling machine, which is composed of a rotating body which supports at least one blade at a peripheral portion for taking out a label from a label magazine after passing through an adhesive portion first. Is all achieved by The blade is partially rotated about its support axis, the support axis being opposite two about a pivot axis.
A gear mechanism associated with a toothed fan that partially rotates in one direction. The blade is connected via a support shaft to a movable body arranged in the peripheral portion of the rotating body, and a bending element is fixed to the movable body, and the bending element has a curvature similar to that of the blade. And is disposed on the orbit of the blade in the movement direction of the rotating body. The curving element receives the adhesive as it passes through the adhesive and removes a portion of each one label that further exceeds the length of the active curving surface of the blade. The invention further comprises a slide wheel member slidable in a track for moving the movable body in an outward direction with respect to the rotating body, whereby the blade can come into contact with the label, which is attached to the label. Remove from magazine.

Further features and advantages of the invention will become apparent from the detailed description of an embodiment of the invention which follows, in the form of a non-limiting example in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, reference numeral 1 designates a conveyor (not shown for simplicity) which feeds bottles, bottles or other containers by a transfer wheel 3 to a rotating structure 2.
The label is applied to the bottle of the rotating structure 2 by the drum 4, after which the bottle is removed by a further transfer wheel 5 and placed on the conveyor 6. The arrow in FIG. 1 indicates the moving direction of the bottle.

In the drawings, reference numeral 7 indicates a label ejecting device of the present invention, and at the same time, reference numeral 8 indicates an adhesive portion,
Reference numeral 9 indicates a label magazine. Other than the label ejecting device 7, other mechanisms are of known type and will not be described further below.

The label take-out device 7 comprises a rotating body 11 which supports the blades 12 around its circumference, each blade 12 first passing through the bond 8 and then the label magazine 9.
It comprises a curved active surface 13 for independently removing the label from. Basically, the rotating body 11 includes a pair of gears 15 and 16
It comprises a cover (shown in FIG. 8 at 11) which is driven by a shaft 14 which is moved by means of a gear 16 which is fixed to a shaft 17.

Each blade 12 has its own support shaft 1
8 about which a further gear 19 is stopped, on which an idler gear 20, another gear 21 and a pivot axis fixed to the rotating body 11 are rotated. Toothed fan 22 that partially rotates in two directions
Moved through and.

The toothed fan member 22 is partially rotated in two directions by including a first sliding member 24 in which the toothed fan member 22 is slidably inserted in a first track 25. In the embodiment shown, there are effectively two trajectories 25.
Exists, but one is sufficient if the configuration of other components is changed. In either case, track 25
Is basically circular and is provided on the fixed base portion 26 of the rotating body 11. As can be seen from FIG. 3, in the vicinity of the label magazine 9, the curve of the first track 25 is that the track 25 is L1.
In the range indicated by, the point is inside the fixed base portion 26 from the previous track and deviates from the circular shape. This change in the orbit causes the sliding member 24 to move radially toward the center with respect to the fixed base 26, causing the orbit to deviate from the circular shape, thereby causing the toothed fan-shaped member 22 to rotate about the pivot axis 23. Rotation of the blades 12 about the support axis 18 occurs.

Via the support shaft 18, each blade 12
Is connected to a movable body 27 having a substantially unequal quadrilateral shape, to which gears 19, 20 and 21 are fixed.

The bending element 28 is rigidly fixed to the movable body 27 and has an active surface 29 provided with a curvature similar to the surface 13 of the blade 12, and a circular path of the blade 12 in the direction of rotation of the rotor 11. Is installed in.

The curved element 28 receives the adhesive as it passes through the adhesive 8, and then covers the surface 29 (here the adhesive is removed) of all of the label 10 removed by the blade 12 covering the surface 13 of the blade 12. Take out). This continuous movement is shown in FIGS.

The movable body 27 is moved radially relative to the rotating body 11 in the centrifugal direction, whereby the blade 12 is moved.
Comes into contact with the label 10 included in the label magazine 9 (rotational non-pulling contact generated by rotation of the toothed fan-shaped member 22)
To do. This movement is made possible by the presence of the second sliding member 30 connected to the movable body 27 slidably inserted in the second circular track 31 provided on the fixed base portion 26. Figure 3
As can be seen from the above, in the area of the label magazine, the second circular orbit 31 is not a perfect circle but is deviated from a circle, and is an area L2 extending outward from the fixed base portion 26. This change in the trajectory causes a radial (relative to the fixed base 26) movement of the second sliding member 30 in the radial direction and thus a movement of the movable body 27.

At the downstream side of the label magazine 9, the rotating body 11
In the direction of rotation, the idler roller 32 (shown in FIGS. 4 and 7) is mounted and presses the label 10 against the surface 29 of the curved element 28 so that the label 10 is correctly positioned.

What is clear from the research on the subject is 400 mm.
With a label take-out device 7 having a standard diameter of 600 mm,
Labels of moderate length are used, which include locating labels of sufficient length to enclose a container of considerable circumference, all of which are possible with prior art solutions. That is.
