Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a labeling device for a bottle labeling machine.

Conventionally, label pasting machines are broadly classified into continuous rotation type, continuous linear type, intermittent movement type, etc. The continuous rotation type is
The bottle is held on a disc and is affixed with a label by a roller or the like while it is rotating.In the continuous linear type, the label is affixed by a roller or the like while the bottle is moving straight. In the intermittent movement type, the bottle moves intermittently and the label is applied by a labeling device while the bottle is stopped.

Continuous rotation type or continuous linear type labeling machines are:
Suitable for fast labeling of bottles of the same shape or similar. However, if such a machine were to be made to be able to be used for a wide variety of bottles from the beginning, the machine would be large and the jig would also be large, making it quite expensive. In addition, if the bottle is modified every time it is used for a different shaped bottle, it would take a considerable amount of time and cost a lot of money. On the other hand, it is difficult to increase the speed of an intermittent movement type labeling machine as much as a continuous rotation type or continuous linear movement type labeling machine, but it is possible to make different shapes by simply replacing the jig or modifying it. It has the feature that it can be easily adapted to bottles.

The present invention particularly relates to a label applicator for an intermittent moving type label applicator.

[Conventional technology]

An example of a label pasting device of a conventional intermittent movement type label pasting machine is shown in FIGS. 3 and 4. These figures are explanatory views showing the label holding state and label pasting state of this label pasting device, respectively.

In these figures, 31 is a labeling device;
2 is the conveyor, 33 is the bottle, 4 is the grip arm,
5 is the shaft of the grip arm, 6 is a stopper provided on the stand of the label pasting machine, 37 is a leaf spring,
8 is a lower part, 9 is a support frame thereof, 10 is a pivot shaft between the support frame and the grip arm, 11 is a spring that pushes the support frame back to a predetermined position, 12 is a stopper that defines the position of the support frame when attaching a label; 43 is the upper part, 44 is its support base, 45 is a pivot shaft between the support base and the support frame, 46 is a rod that pushes the upper part towards the bottle, 47 is a fine adjustment spring, and 48 is the pulled back position of the upper part. The stoppers 24 and 25 defining the label are attachment ports for a suction hose for suctioning and holding the label.

In this conventional labeling device, as shown in FIG. 3, a support frame 9 that is pivotally supported on a grip arm 4 by a pivot shaft 10 maintains a predetermined position by the pushing force of a spring 11. A support stand 44 pivotally supported on the support frame 9 by a support shaft 45 is supported by a leaf spring 37.
By maintaining the position defined by the stopper 48 by pulling back the rod 46, the surface of the lower pad 8 and the surface of the upper pad 43 are placed on the same plane, and in this state, the label is removed from the label supply device. aspirate and hold the label.

From this state, the grip arm 4 rotates in the direction of the arrow, and when the stopper 12 of the support frame hits the stopper 6 of the pedestal, the support frame 9 rotates around the tip of the stopper 12 so that its lower part protrudes toward the bottle barrel. At the same time, the rod 46 is pushed by the leaf spring 37 and protrudes in the direction of the bottle neck, causing the support base 4
4 rotates obliquely downward around a pivot shaft 45.

As a result, as shown in FIG. 4, the bottle body and bottle shoulder of the bottle 33, which has been conveyed by the moving conveyor 2 and stopped perpendicularly to the page, for example, from the front to the opposite side of the page, are simultaneously struck. Labels can be attached.

This conventional labeling device was further improved to allow labels to be applied to the bottle body, bottle shoulder, and bottle neck at the same time (Utility Model Publication No. 58-15288).
is also known.

In this device, a support stand for the shoulder part is pivoted on the upper part of the support stand for the lower part, and a support stand for the upper part is further pivoted on top of the support stand, and it can be used to hold items such as brandy bottles. This product is suitable for attaching labels to the bottle body, bottle shoulder, and neck of bottles with smooth shoulders.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional labeling device, the support base of the upper part is pivotally supported by the support base below it, and the movable range of the upper part is limited to the range that can be pushed by the leaf spring. Because of this, traditional labeling equipment
For bottles such as narrow-necked whiskey bottles, the radius of the bottle body and the radius of the bottle neck are very different.
It was not possible to attach labels to the bottle body and bottle neck at the same time.

[Means for solving problems]

In order to solve these problems, the inventors of the present invention created an intermittent movement type labeling machine that, when the bottle is stopped, makes a reciprocating arc movement in a plane perpendicular to the bottle's movement direction with the bottom end as an axis, and The grip arm has an extended leaf spring, the lower part is pivotally supported by the grip arm, the lower part is provided on the bottle side of the lower part for holding the label on the bottle body, and the upper part is provided with a frame-shaped part. A pivot pin is passed through both walls of the lower part of the frame-shaped part, and a restraining plate is installed on the lower side of the upper wall of the frame-shaped part.
In addition, a support frame is provided at the upper end of the frame-shaped part with a stopper that comes into contact with the stand stopper of the labeling machine to adjust and regulate the overall inclination during labeling, and a space between the support frame and the grip arm. A spring is installed on the support frame to restore the original tilt after the label is pasted, and on the bottle side there is an upper part that holds the label on the bottle neck.
In addition, a horizontally elongated hole into which a pivot pin is inserted is provided at the bottom, and a support stand is held within the support frame so as to be movable in the direction of the bottle and rotatable around the pivot pin, and the front and back of the support stand. The support mechanism is connected at two points and adjusts and regulates the inclination of the upper part when labeling. It consists of two rods of approximately equal length that are mutually pivoted at one end, and can be bent and stretched with the pivot axis facing upward. The contact rotation roller provided on the pivot shaft is provided between the support mechanism and the leaf spring of the grip arm, and when the label is pasted, the contact rotation roller that is provided on the pivot shaft contacts and rotates against the holding plate of the support frame and is pushed down.
The bending and extending arm pushes out the upper part provided on the support base to the neck of the bottle via the support mechanism by extending linearly from the folded state in a dogleg shape, and the support base and grip arm. To provide a label pasting device characterized by comprising a spring provided between a leaf spring and a spring that bends a bending/extending arm via a support stand and returns an upper part to its original position after pasting a label.

The first structural feature of the labeling device according to the present invention is that a horizontally elongated hole through which a pivot pin is inserted is provided in the lower part of the support base, which is provided with an upper part for holding the bottle neck label on the bottle side. , the support stand is held within the support frame so as to be movable in the direction of the bottle by the length of the horizontally elongated hole, and to be rotatable around the pivot pin. A flexible arm consisting of two supported rods of approximately equal length is provided between the support mechanism of the support base and the leaf spring of the grip arm so that it can be bent and extended with the pivot axis facing upward, and the arm is made of two supported rods of approximately equal length. The contact rotation roller provided on the shaft rotates in contact with the restraining plate of the support frame and is pushed down, causing the bending arm to extend linearly from its folded “dog” shape, thereby causing the support mechanism to move. The upper part provided on the support base can be pushed out to the neck of the bottle through the bottle.

[Effect]

In the labeling device according to the present invention, the upper part that holds the label on the bottle neck can be moved over a long distance from a predetermined position to the bottle neck by the following action.

A spring provided between the support frame and the grip arm pulls the support frame back to the specified position, and a spring provided between the support base and the leaf spring pulls the support base back to the specified position. When the support frame is pivoted upward from the side and the stopper of the support frame comes into contact with the gantry stopper, as the grip arm rotates, the support frame rotates about the tip of the stopper of the support frame as an axis so that its lower part protrudes.

In this case, the movement of the pivot point of the support frame near the rotation axis of the grip arm is small, but the movement of the tip of the leaf spring extending on the grip arm far from the rotation axis of the grip arm is large.

On the other hand, since the support frame rotates around the tip of the stopper of the support frame, the movement of the upper part of the support frame near the stopper is even smaller than the movement of the pivot point of the support frame.

Therefore, the relative movement distance of the tip of the leaf spring with respect to the upper part of the support frame becomes very large.

Furthermore, when the tip of the leaf spring approaches the support frame in this way, the contact rotation roller provided on the pivot shaft of the bending/extending arm comes into contact with the restraining plate of the support frame.
As the bending arm is pushed down while rotating and extends linearly from the folded "dog" shape, the tip of the bending arm moves farther than the tip of the leaf spring.
