Description

Description: TECHNICAL FIELD The present invention relates to a label supply device for supplying a label to a cavity forming wall surface during molding of plastic.

(Prior Art) Conventionally, as an invention relating to a label feeding device,
There is one disclosed in the patent publication of No. 54576.

This label supply device is used for a blow molding device in which a parting line is set obliquely with respect to the opening and closing directions when the mold is clamped and when the mold is opened. A label holder that has a head that adsorbs a label at its tip, and a label holder that is set at a right angle to the advancing / retreating direction of the label holder and that stacks the labels. And a head for taking out the label is provided at the tip of the label holder, and the head is rotatable.

The means for rotating the head is composed of a cam plate disposed on the side of the label holder and extending in the advancing / retreating direction of the label holder, and a compression spring for pressing one end of the head against the cam plate.

(Problems to be Solved by the Invention) However, such a conventional label supply device for a blow molding device can be used only for a special mold in which the parting surface is inclined with respect to the opening / closing direction of the mold, and therefore, the label supplying device cannot be used. It cannot be used for a normal mold whose opening and closing direction is orthogonal to the ring surface, and lacks versatility of the label supply device, and in order to make the head face the cavity forming wall surface of the mold, In addition to requiring a large opening and closing stroke of the mold, in order to reciprocate the label holder at right angles to the cavity forming wall of the mold in the mold open state, the reciprocating stroke of the label holder must be long. There is a problem that the entire molding apparatus becomes large.

(Means for Solving the Problems) In order to solve the above problems, the label supply device according to the present invention is provided on a cavity forming wall surface of a mold in which a mold opening / closing direction is set substantially at right angles to a parting surface. A label supply device having a label disposition position having an inclination angle with respect to the parting surface and supplying a label to the label disposition part, wherein the expandable and retractable member is parallel to the parting surface. The label suction member for supplying the label to the label disposing position is attached so that the angle can be adjusted so as to have a predetermined inclination angle with respect to the parting surface.

(Operation) According to the label supply device of the present invention, even if the label disposition position on the cavity forming wall surface is inclined with respect to the parting surface, the advancing direction of the label suction means is Since the label can be directed at a right angle to the label placement position, the label can be set at this label placement position by advancing and retracting the label suction means.
