Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a labeling device, and particularly to a labeling device suitable for affixing a label to a container such as a tapered bottle.

``Prior Art'' Conventional general labeling devices include a labeling drum that can rotate freely once, a label holding section provided on the labeling drum, and a supply mechanism that supplies labels to the label holding section. The original label is held by the label holding section and affixed to the container.

By the way, if the outer circumferential surface of the container is inclined, such as a tapered bottle, it is necessary to tilt the container or the label holder so that the label can adhere to the outer circumferential surface of the container. Since the label is attached at an angle to the outer peripheral surface of the container, it is necessary to attach the label to the container at an angle in advance.

For this reason, in the past, for roll labels, the label was printed at an angle, then the label was punched out at an angle with a Gui-Cut roll and held in a label holder, or in the case of sheet-fed labels, the label was printed at an angle. The magazine was tilted, and the label was skewered and held in the label holder while the magazine was tilted.

"Problems to be Solved by the Invention" However, if labels are printed at an angle on a roll label, not only will the number of labels that can be printed within a certain length decrease, but it will also be difficult to finely adjust the inclination. It becomes possible. In addition, in any case, the label holding section will hold the tilted label, and the label tilt changes depending on the degree of tilt of the outer peripheral surface of the container, so when changing the type of container, etc. In this case, the state of supply of labels to the label holding section fluctuates, which may make it difficult to always ensure stable delivery.

1. In view of such concerns, the present invention provides a system in which the label holding section is rotatably provided on the labeling drum, and the label supplied from the supplying mechanism to the label holding section is The label is attached to the container after being rotated by the required amount by rotating the label holder.

"Function" According to such a configuration, the labels supplied to the label holder can always be supplied to the label holder in a constant state even if the inclination angle of the outer circumferential surface of the container changes. By simply adjusting the amount of rotation, labels can be easily supplied and attached to various containers in an appropriate state.

"Example" The present invention will be described below with reference to the illustrated embodiment. In FIG. 1, l is a roll label wound on a supply reel (not shown), and a roll label l pulled out from the supply reel
is a die-cut roll 2.2 that constitutes the label supply mechanism.
A label 3 having a desired shape is punched out by this die-cut roll 2.2. The punched labels 3 are then supplied to a label holding section 5 provided on the labeling drum 4 and held by means such as negative pressure, while the label waste 6 from which the labels 3 have been punched is transferred to a take-up reel (not shown). It is wound up.

The label 3 that is horizontally attracted to the label holding section 5 passes through the gluing roller 7 in that state, and glue is applied to the back surface of the label 3, and then the label 3 is attached to the label holding section 5.
is tilted from the above-mentioned horizontal state to a required angle by rotation.

On the other hand, the containers 11 transported by the transport conveyor IO are spaced apart by a required interval by a timing screw (not shown), and are synchronized with the rotation of the labeling drum 4. Each container 11 is rotated while being held between the label holding part 5 and a fixed arc-shaped pressure pad 12 at the contact part with the label holding part 5 provided on the labeling drum 4. As a result, the label 3 tilted from the horizontal position by the required angle by the label holder 5 is stuck to the outer peripheral surface of the container 11 by the adhesive force of the glue.

At this time, the container 11 is formed into a tapered shape as shown in FIG. Each container 11 is transported tilted. and container 11
The label holder 5, which has become empty after pasting the label 3 on the outer circumferential surface of the holder, is returned to its original horizontal state, and the above-mentioned Duiker/) is returned to its original horizontal state.
The label 3 supplied from the roll 2 is held. It goes without saying that the labeling drum 4 may be tilted instead of the container 11.

However, a plurality of the label holding parts 5 are provided at equal intervals on the outer peripheral surface of the labeling drum 4, and each label holding part 5 is attached to the rotary plate 13 constituting the labeling drum 4, as shown in FIG. It is attached to the tip of a rotating shaft 14 which is arranged in the radial direction and rotatably supported. A worm wheel 15 is attached to the end of each rotating shaft 14, and each worm wheel 15 is meshed with the worm IB.

Further, each of the worms 16 is attached to a rotating shaft 17 that is disposed vertically and supported by the rotating plate 13, and a cam follower 19 is provided at the tip of a lever 18 that is attached to the upper end of each rotating shaft 17. Each cam follower 19 is engaged in a cam groove 21 of a cam plate 20 arranged and fixed above the labeling drum 4.

Therefore, when the labeling drum 4 is rotated, the rotating shaft 17 is rotated via the cam follower 18 and the lever 18 according to the shape of the cam groove 21, and as a result, the worm 16, and the rotating shaft 1 via the worm wheel 15 meshed with the worm wheel 15.
4 is rotated, the label holding section 5 can be rotated.

Furthermore, as shown in FIG.
When the label holding section 9 is held at a predetermined position, the label holding section 5 can be tilted from a horizontal state to a maximum inclination angle.

Then, when the label holding part 5 is tilted to the maximum tilt angle indicated in E, the tilt angle of the label 3 is too large.
If the label 3 is attached diagonally to the container 11 because it does not match the taper angle of the rotary plate 1,
The stopper port 23 provided at the container 3 is adjusted to regulate the swinging angle position of the lever 18 so that the label 3 can be correctly attached to the container 11. At that time, the cam follower 18 can be displaced relative to the lever 18 whose swing is restricted by the stopper port 23 against the spring 22.

In the above embodiment, the labels 3 are punched out from the roll label l, but it is of course possible to use sheet labels separated one by one. In addition, instead of attaching the label 3 adsorbed by the label holder 5 directly to the container 11, the label 3 adsorbed by the label holder 5 is tilted to a required angle by rotation of the label holder 5, and then the label 3 is transferred at an appropriate angle. It may also be delivered to a drum and affixed to the container from this delivery drum.

Further, in the above embodiment, the rotation angle of the label sticking part 5 is adjusted by the stopper port 23 according to the degree of taper of the container 11, but a servo motor such as a stepping motor is used as the drive source, and By detecting the inclination of the pasted label with an appropriate detector and feeding it back, the appropriate rotation angle of the label pasting section 5 may be automatically obtained. Adjustment work becomes easier.

Further, in the above embodiment, the label holder 5 is rotated in order to properly attach the label 3 to the container 11 such as a tapered bottle, but the present invention can also be applied to a normal container. can. That is, especially when the aspect ratio of the label 3 is large, the label is printed in the vertical direction on the roll label.

A label supplied to the label holding part 5 in the vertical direction can be rotated by 90 degrees in the label holding part 5 to be in the horizontal direction, and can be stuck to the container in that state. In this way, a large number of labels can be printed on a roll label of a constant length. Of course, such vertical label printing on a roll label may be performed when the container is a tapered bottle or the like.

"Effects of the Invention" As described above, according to the present invention, since the label can be tilted by rotating the label holding section, even when the inclination angle of the label is changed, the label feeding mechanism does not reach the label holding section. Labels can be supplied under substantially the same conditions, resulting in the effect that stable delivery can be achieved.
