Abstract

A label taking and placing device includes a label-storing chamber for storing labels and a label-taking unit consisting one or more label mold bases, which are respectively provided with a plurality of air holes, and a label placing unit. When the label mold base is moved to touch one of the labels, the label is sucked to the label mold base by means of air sucking through the air holes. Then the label mold base with the label sucked thereon is moved into a forming mold. The label-placing unit is located at the front of the label mold base, and when the label mold base is moved in the forming mold, the label is taken off and placed in the forming mold by the label-placing unit. Then the label can be stuck on a plastic product during its forming process in the forming mold.

Description

1235727 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a label take-out / placement mechanism, and more particularly to a label take-out / placement mechanism in a plastic mold for injection or extrusion molding of plastic products. The plastic product and the label are made into one body, so as to achieve the function of automatic production of plastic product in-mold molding. [Previous technology] According to the commercially available plastic products, in order to make the surface of the plastic products have an excellent decorative beauty, it is formed by in-mold labeling, which has become a trend. In order to manufacture in-mold plastic products by in-mold labeling, The pre-printed label must be placed in the molding mold. After the plastic product is shot or extruded in the molding mold, the label can be combined with the plastic product. This is an in-mold molding method. However, to put the label into the forming mold, before that, there is the announcement No. 538956 "suction removal unit for labeling machine in plastic film", in which the vacuum suction channel is set in the body, and the vacuum suction channel passes through A vacuum generator generates a vacuum. After the body is in contact with the adsorption tank, the label can be adsorbed and sent into the molding mold of the plastic product. However, this case is only for the adsorption of the label, and it does not actually solve the problem of the label entering the molding mold. The electrostatic effect of the vacuum generator or the body may cause the label to be taken away or deviated from the molding when the body leaves the molding mold. Moulds cause the instability of the combination between plastic products and labels, resulting in poor yield of finished products. Therefore, the present inventor has accumulated many years of experience in the design and development of new product structures and molding dies, and has studied the shortcomings of those who have previously learned and invented the present case.
