Example Embodiment

[0018] Example 1

[0019] Hereinafter, the embodiments of the present invention will be described in accordance with the drawings.

[0020] in Figure 1 to Figure 4 In the sheet take-out device 1, when the sheet 19a is installed in, for example, a mold of an insert molding machine (none of which is shown), it takes out one sheet at a time from the sheet group 19 in which a plurality of sheets 19a are stacked. The device for sequentially taking out the uppermost sheet 19a has five guide posts 5 arranged at predetermined intervals on the main body 3. The guide posts have an axis in the vertical direction and are constituted by a predetermined axis length. Each guide column 5 supports a bearing plate 7 as a support member that can move in the up and down direction. Moreover, the front (front side) and rear (rear side) of the carrier plate 7 are provided with mounting shafts 9 respectively, and upper and lower frames 13 are respectively erected on both sides, and a pair of front and re...

Example Embodiment

[0038] Example 2

[0039] In this embodiment, an ion generator (not shown) is connected to an air supply device (not shown) that ejects air from the air ejection holes 11a provided on each mounting plate 11, and the ejected air becomes charged ion wind. In this way, when static electricity is generated in each sheet 19a of the sheet group 19, the static electricity is electrically neutralized and removed due to the charge of the ion wind, thereby preventing the sheets 19a from being electrostatically attracted to each other.

Example Embodiment

[0040] Example 3

[0041] In this embodiment, a charge generating device such as a discharge device or an ion generator is provided at the holding position formed by the adsorption member 35 to charge the air around the holding position. When static electricity is generated on each sheet 19a in the sheet group 19, the air with the required charge generated by the static electricity generating device is used to neutralize and remove the static electricity of the sheet 19a to prevent the sheets 19a from being electrostatically attracted to each other , It is possible to restrict the simultaneous extraction of a plurality of sheets 19a.

Abstract

A sheet-extracting device comprises a support member on which a group of sheets layered is put; a lifting and lowering member lifting and lowering the corresponding support member; adsorption members adsorbing a sheet of the uppermost layer of the group of sheet put on the support member; a vertical moving member vertically moving each adsorption member; a horizontal moving member moving each adsorption member to a direction close to each other and a direction distant from each other; an air injection member injecting air toward at least upper sides of the group of sheets put on the support member; and a separation member elastically deforming by coming in contact with edge of the sheet held on the adsorption member.

Description

technical field [0001] The present invention relates to a sheet take-out device and a take-out method for taking out the uppermost sheet one by one from a stacked sheet group when the sheet is installed in a mold of an insert molding machine, the insert molding The machine integrally forms synthetic resin on a sheet or label (hereinafter referred to as sheet) made of synthetic resin, such as printing a desired pattern or characters. Background technique [0002] A technique for mounting a synthetic resin sheet in a mold in an insert molding process such as integrally molding a synthetic resin by injection molding or hollow molding on a sheet, the mounting method described in Patent Document 1 is known. This installation method involves the following technology: In order to avoid the difficulty of installing in the mold in a predetermined state due to the static electricity of the sheet installed in the mold itself, an electric field can be applied to the held sheet to achiev...
