摘要:
An object of the present invention is to achieve increase in feed-out speed while having a freedom of selecting stacked objects from a wide range of objects by securing a stable separating and feed-out function of feeding out stacked objects one by one from a surface thereof. A stacked object feed-out apparatus A1 separates and feeds out the stacked paper sheets P from a paper sheet at a surface position to a business machine 9, the stacked paper sheets P stacked on a paper sheet housing member 1. The stacked object feed-out apparatus A1 includes: an electrostatic attraction belt 6 which is passed around a drive roller 7 and a driven roller 8 and in which multiple electrodes 28 are covered with an insulating layer 29; an electrostatic attraction control circuit 30 which is connected to the multiple electrodes 28, and which performs application of voltage and cutting of the applied voltage; an object feed-out mechanism 11 which feeds out by belt rotation a feed-out paper sheet Pa electrostatically attracted to a belt holding surface 6a of the electrostatic attraction belt 6; and an electrostatic attraction belt moving mechanism 10 which brings the belt holding surface 6a and the stacked paper sheets P close to or in contact with each other in the attraction and moves the belt holding surface 6a and the stacked paper sheets P away from each other in the feed-out by adjusting a relative gap between the belt holding surface 6a and the stacked paper sheets P.

A reinforcement apparatus is for reinforcing a thin plate-like reinforcement object which is required to be temporarily reinforced in operating processes. The electrostatic-type reinforcement apparatus includes a reinforcement material body including a thin plate type electrostatic holding part formed by burying an electrode part into an electric insulating layer, and a voltage controller constituted to be separated from the reinforcement material body and having a first connecting terminal configured to allow an reinforcement object conducted to an earth and a second connecting terminal configured to allow the electrode part to be conducted to an earth or a high voltage. The voltage controller includes an attracting process part configured to attract the reinforcement object by generating an attraction force in the electrostatic holding part by supplying an electric charge of a reverse polarity to the charges supplied to the electrode part to the reinforcement object from the earth and an attraction releasing process part configured to cancel an electrostatic attracting ability by releasing charges stored in the reinforcing object and the electrode part from the earth.
摘要:
An electrostatic holding device (100) in which an electrode group (103) having a plurality of electrodes covered with an insulating material (102) is used as a holding surface applies predetermined voltage to the electrode group (103) to hold a holding object (104) by an electrostatic force with a contact state or with a floating non-contact state. The electrostatic holding includes an internal polarization eliminating device (applied voltage control portion 105) to eliminate the internal polarization generating in the insulating material (102) by switching the polarity of voltage to be applied to the electrode group (103). There are provided with the electrostatic holding device in which the electrostatic attraction does not deteriorate by usability, and electrostatic tweezers in which the electrostatic attraction does not deteriorate when the tweezers are manually used.
