Problems solved by technology
However, even if such a method is adopted, not only the replacement of the label box itself is troublesome, but also the operation of the label conveying device must be stopped during each replacement, and the situation of reducing the production efficiency of the in-mold forming has not changed.
[0005] Moreover, in the technology described in Patent Document 1, after the label is absorbed by the suction device, the label is directly transferred to the winding table, so the arrangement position of the label box and the structure of the suction device are limited.
Specifically, the structure of the take-out device for taking out labels from the label box and the structure of the label conveying device for conveying the taken-out labels to the winding table are limited separately, so there is a problem that the design freedom of the label supply device is reduced.

Embodiment Construction
[0045] Next, the best embodiment of the present invention applied to the in-mold forming system will be described with reference to the drawings. Fig. 1 is a schematic plan view showing an embodiment of an in-mold forming system including a label conveying device of the present invention. Fig. 2 is the II-II arrow view of Fig. 1 . image 3 It is an enlarged longitudinal sectional view showing an example of an in-mold molded product. In addition, the drawings are all explanatory diagrams, and parts are exaggeratedly drawn for easy understanding, and the dimensional ratio of each part is different from the actual dimensional ratio.
[0046] 1, 2 and 3, the in-mold molding system 1 includes: an injection molding machine (in-mold molding machine) 2; a label supply device 3 that supplies labels L to a fixed mold 21 included in the in-mold molding machine 2; The label box 4 that has a plurality of labels L extracts the label take-out mechanism 50 of the label L on the bottom layer;...

The present invention provides a method and apparatus for transferring labels, capable of avoiding the decrease of the production efficiency of the transferring apparatus by complementarity of labels when a in-mold forming system is running. In the in-mold forming system (1) of the invention, the most sublayer labels are separated and abstracted through a label outlet (4a) of a label box (4) from the labels (L) overlapped in the label box (4) by a label take-off device (50). The width direction two end edges of the abstracted most sublayer labels (L) are transferred by a label transferring device (51). Even though the label transferring device (1) containing the label take-off device (50) is running, the label (L) may be complemented through a label inlet (4b) of the label box (4).
Description
technical field [0001] The present invention relates to a label conveying method and a label conveying device for conveying a label into a mold of an in-mold forming machine. Background technique [0002] Figures 1 and 4 of Japanese Patent No. 2797043 (Patent Document 1) disclose a kind of air suction through a suction device, winding a label on the periphery of a simulated core and entering the injection molding mold to be wound on the simulated core Apparatus and method for conveying labels to an existing injection molding die for supplying labels in a state. In this prior art, a label case for accommodating a plurality of labels is arranged in a horizontal state. In addition, using a suction device equipped with a suction cup, the label is sucked from a label extraction port provided at one end of the label box with the suction cup, and the label is taken out in a horizontal direction. After that, move the taken out label, move the label to the winding table, and carry ...
