Description

  The present invention relates to a label sticking apparatus, and more particularly, to a label sticking apparatus capable of sticking a label even when the transport direction of an adherend to which the label is stuck is changed.

  A known label sticking device adsorbs the label with the suction plate in accordance with the timing of peeling the label temporarily attached to the strip-like release sheet, and presses the suction plate against the surface of the adherend to be conveyed. The structure which affixes to an adherend is employ | adopted. However, in the case of this label sticking apparatus, when the flat area of the label is large, the pressing force by the suction plate may not reach the entire surface equally, and there is a disadvantage that a partial sticking failure occurs.

  Thus, for example, as shown in Patent Document 1, a label sticking device is proposed in which a pressing roll is arranged on one end side of the suction plate, and a label can be stuck while applying a pressing force to the label with the pressing roll. ing.

Japanese Patent No. 3370722

  However, in the label sticking device described in Patent Document 1, when the transport direction of the adherend is one direction, no particular inconvenience occurs, but the transport direction of the adherend is opposite. Requires a labeling device corresponding to this, which lacks versatility and increases equipment costs. That is, there is an inconvenience that it is necessary to prepare another label affixing device opposite to the desired one depending on the transport direction of the adherend.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and its purpose is to provide a versatile label that enables label sticking without being restricted by the transport direction of the adherend. It is to provide a sticking device.

In order to achieve the above object, the present invention provides a suction plate for sucking and holding a label, a pressing roll disposed on one end side of the suction plate for applying a sticking pressure to the label, and rotating the suction plate in a plane. A rotation mechanism; a plate support that supports the suction plate so as to be swingable; and an angular displacement unit that angularly displaces the suction plate; and a label that is sucked by the suction plate by angularly displacing the suction plate. In a label sticking device that sticks to adherends that are sequentially conveyed,
The rotation mechanism is provided between the plate support and the suction plate, and the suction plate is supported by the plate support through the rotation mechanism,
The suction plate includes a plurality of connecting portions that specify connection positions to which the angular displacement means can be selectively connected. When changing the connection position, the suction plate is attached to the plate support via the rotation mechanism. composed supported state, the suction plate by causing a predetermined angle in a plane by the rotating mechanism, and can be changed the position of the pressing roll so as to correspond to the change in the conveying direction of the adherend, as Is adopted.

  In the present invention, the angle displacing means may be constituted by a cylinder and connected to the connecting portion of the suction plate via a connecting member provided on one end side of the cylinder.

  Preferably, a stopper is provided between the suction plate and the plate support, and the relative position between the suction plate and the plate support is regulated by the stopper.

  In the present invention, the suction plate is angularly displaced in a state where the pressing roll is located on the downstream side in the conveyance direction of the adherend, and the adherend passes under the pressing roll in this state, whereby the label is applied with pressure (pressing force). It will be affixed while receiving. Here, when the transport direction of the adherend is opposite, the connection of the angular displacement means to the suction plate is released, and after the suction plate is rotated approximately 180 degrees in the plane, the angular displacement means is changed to the suction plate. By reconnecting, the position of the pressing roll can be set to the opposite side, and thereby, it is possible to provide versatility that enables labeling by the same device even when the transport direction is reversed. .

  Further, according to the configuration in which the pressing rolls are symmetrically arranged on both end sides of the suction plate, a rotation mechanism for rotating the suction plate in a plane can be omitted, and the connecting portion for connecting the angular displacement means to the suction plate It is possible to simplify the configuration with a single location. Further, even if the transport direction is different by about 180 degrees only by a very simple operation for changing the angle of the suction plate, it can be applied without difficulty.

It will be located on the tip side of P. And the label L peeled at the front-end | tip of the peel plate P advances along the adsorption | suction surface 11B, and the one end side is located in contact with the outer peripheral surface of the press roll 12 in the state which peeled completely. It will be. When the label L travels along the suction surface 11B, air may be blown from below the label L by an air assist device (not shown) to prevent the label L from falling off.

  Assuming that the adherend W is transported from the left side to the right side as shown in FIG. 4, the vertical cylinder 27 is lowered, and the cylinder 40 of the angular displacement means 15 is at the advancing limit at the initial position. The piston rod 43 is moved back to the retreat limit by switching a solenoid valve (not shown), and the suction plate 11 is angularly displaced so as to incline to the right. In this state, when the pressing roll 12 comes closest to the adherend W and the adherend W passes under the pressing roll 12 to the right side, the right end side of the label L adheres to the adherend W, and the pressing roll The films are sequentially pasted while receiving 12 pressing forces.

  Further, when the transport direction of the adherend W is opposite, that is, as shown in FIG. 5, when the adherend W is transported from the right side to the left side, the connecting member 45 is fixed to the suction plate 11. The screw 48 is removed from the screw hole 11C to release the connection.

Therefore, even when the conveyance direction of the adherend W is opposite, the effect that the label L can be attached to the adherend W by exactly the same action is obtained.
As for the movement of each piston rod of the angular displacement means, the conveyance direction of the adherend W may be manually input to an operation input device (not shown), but a sensor is attached to the suction plate, and the suction plate moves in either direction. It is also possible to control a solenoid valve (not shown) by automatically detecting whether it is suitable.
