Description

1259162 V. INSTRUCTION DESCRIPTION α) [Technical Field of the Invention] The present invention relates to an in-mold labeling labeling/setting device (1), and more particularly to a mechanical arm for driving a fixing seat, and then using a fixing seat side The finished product take-out device takes out the plastic finished product from the mold, and takes the labeling device to take and put the label, and puts it into the forming mold. After the plastic product is formed, the plastic finished product in which the in-mold labeling label is integrally formed can be obtained. The in-mold labeling tag takes/places the device. [Prior Art]

According to the currently available plastic products made of plastic materials, in order to make the plastic products have better decorative effects, in the process of injection or extrusion of plastic products or vacuum forming, the labels are pre-placed into the molding die, and the molds to be molded are After molding plastic products, the in-mold label forming method that combines labels and plastics is gradually studied and discussed by domestic plastic molding manufacturers. In the manufacturing process of the above-mentioned in-mold label forming method, pre-printing will be carried out. The finished label is first placed in the molding die. When the plastic product is shot or extruded or vacuum molded in the molding die, the label can be combined with the plastic product.

In order to put the label into the mold, in addition to the manual insertion method, mechanical equipment is used. Therefore, there is a case in the public notice No. 5 3 8 9 5 6 "Capacity removal unit for the labeling machine in a plastic film film" which is provided with a vacuum suction channel for sucking the label in a body. The vacuum suction channel uses a vacuum generator to generate a vacuum. After the body is in contact with the adsorption tank, the label can be sucked and the label is placed in the molding mold of the plastic product to complete the label removal/setting operation. Only the customary case, only for the adsorption of the label, for the label to be placed into the shape
