Problems solved by technology

[0006] The problem to be solved by the present invention is that in a sheet group formed by stacking sheets that are electrostatically attracted to each other due to static electricity, when the uppermost sheet is adsorbed and taken out one by one, many sheets will be distorted due to static electricity. The sheets are adsorbed to each other and cannot be taken out one at a time

Embodiment 1

[0019] Embodiments of the present invention will be described below with reference to the drawings.

[0020] exist Figure 1 to Figure 4 Among them, the sheet take-out device 1 takes out one sheet at a time from the sheet group 19 in which a plurality of sheets 19a are stacked when the sheet 19a is installed in, for example, a mold (not shown) of an insert molding machine. The device for sequentially taking out the uppermost sheet 19a has five guide posts 5 provided at predetermined intervals on the main body 3, and the guide posts have an axis in the vertical direction and have a predetermined axis length. Each guide post 5 is supported by a support plate 7 as a support member that can move up and down. And the front (front side) and the rear (back side) of this bearing plate 7 are respectively provided with mounting shafts 9, and both sides are respectively erected with upper and lower frames 13, and the top of the mounting shafts 9 is fixed with a front and rear pair of mo...

Embodiment 2

[0039] In this embodiment, an ion generator (not shown) is connected to an air supply device (not shown) that injects air from the air injection holes 11a provided on each mounting plate 11, and the injected 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 neutralized and removed by the charge of the ion wind, thereby preventing the sheets 19a from being electrostatically attracted to each other.

Embodiment 3

[0041] In this embodiment, a charge generator 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. In the case of static electricity generated on each sheet 19a in the sheet group 19, use the air with the required charge generated by the static electricity generating device 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 simultaneous taking out 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...
