Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a label supply device for supplying a label to a cavity forming wall during plastic molding.

(Prior Art) A conventional invention related to a label feeding device is disclosed in Japanese Patent Publication No. 54576/1983.

This label supply device is used in blow molding equipment in which the parting line at the time of mold closing is set diagonally with respect to the opening/closing direction when the mold is closed and opened. A label holder that can move forward and backward in a direction perpendicular to the cavity forming wall surface of the mold and has a head at its tip that attracts labels, and a label magazine that is set perpendicular to the direction of movement of the label holder and stacks labels. A head for taking out the label is provided at the tip of the label holder, and this head is rotatable.

The means for rotating the head includes a cam plate disposed on the side of the label holder and extending in the forward and backward direction of the label holder, and a compression spring that presses one end of the head against the cam plate.

(Problem to be Solved by the Invention) However, the label feeding device of such a conventional blow molding device can only be used for a special mold in which the parting surface is inclined with respect to the opening/closing direction of the mold. Ordinary gold, whose opening and closing direction is orthogonal to the molding surface, cannot be used, and the label feeding device lacks versatility. In addition to having to take a long opening/closing stroke of the mold, the reciprocating stroke of the label holder must be long in order to allow the label holder to reciprocate at right angles to the wall surface forming the cavity. There is a problem that the entire molding device becomes large.6 (Means for solving the problem) In order to solve the above problem, the label feeding device according to the present invention has a structure in which the opening and closing direction of the mold is approximately perpendicular to the parting surface. A label disposing position having an inclination angle with respect to the parting surface is set on a cavity forming wall surface of a mold set in a mold, and a label supplying device supplies a label to this label disposing position, A label suction member that supplies the label to the label placement position is attached to an extensible member that can move back and forth parallel to the parting surface so that its angle can be adjusted so that it has a predetermined inclination angle with respect to the parting surface. It is characterized by the presence of

(Function) According to the label feeding device according to the present invention, even if the label arrangement position on the cavity forming wall surface is inclined with respect to the parting surface, the advancing direction of the label suction means can be adjusted to the direction of the opening of the mold. Since the label can be oriented perpendicularly to the label placement position, the label can be set at this label placement position by moving the label suction means back and forth.
