Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a transfer device of a conductive layer for a collector electrode plate used for assembling a collector of an electrostatic precipitator incorporated in an air cleaner.

[Conventional technology]

The electric dust collector is composed of an ionizer that charges dust particles contained in the air sucked into the machine, and a collector that collects the dust particles charged by the ionizer.

This collector is assembled by alternately stacking a ground electrode plate and a high voltage electrode plate on a frame with a gap therebetween.

As shown in FIGS. 5 to 7, a conductive paint is applied to the conventional collector electrode plate along the central portion of one side of an electrode substrate 1 formed of an insulating sheet such as polypropylene to form a conductive layer 2. In many cases, the spacer protrusion groups 4 and 4 are formed on both insulating portions 3 and 3 of the conductive layer 2.

[Problems to be solved by the device]

In the above-mentioned conventional collector electrode plate, the conductive layer 2 is formed on one surface of the electrode substrate 1 by silk printing, so that it is used when forming the spacer projection groups 4 and 4 on the electrode substrate 1 and when die-cutting the electrode substrate 1. If the pilot hole is to be formed, it is necessary to perform it separately in a separate process, and the manufacturing process of the electrode plate is complicated, and it takes time and effort to manufacture the electrode plate. There was a problem that it was necessary.

Further, as a conventional method for providing a transfer film with a sheet transfer mechanism and a transfer film transfer mechanism, the method of thermocompression bonding is described in, for example, JP-A-48-19309 and JP-A-50-148673. There is such an invention.

However, when transferring the conductive coating film for the collector electrode plate to the insulating sheet surface having a hard sheet surface such as polypropylene, it is necessary to transfer the conductive layer surely and uniformly, but in each of the above inventions Since the sheet and the transfer film are continuously transferred, such transfer is difficult.

An object of the present invention is to provide a transfer device for a conductive layer for a collector electrode, which can solve the above-mentioned conventional problems.

[Means for Solving the Problems]

A large number of conductive coating films for each collector electrode plate are printed with a paint, and transfer films are formed by printing marks on both sides of the film at regular intervals in the film transport direction. Of the film transfer mechanism that transfers the film so that it passes through a position close to the transfer area of
The sheet transfer mechanism and the position sensor that issues a signal to the film transfer mechanism to stop the transfer operation thereof, and the transfer film at a position where the transfer film approaches the insulating sheet when the operation of both transfer mechanisms is stopped. A transfer roll that rolls so as to be pressure-bonded to the insulating sheet while heating, and a transfer roll that transfers the conductive coating film to the insulating sheet, and a receiving roll thereof, and both sides of the insulating sheet in a transfer area of the transferred insulating sheet. The punching device is provided with a pilot hole along the portion, and a control mechanism for controlling both of the transfer mechanisms so that they start the transfer operation immediately after the transfer is completed.
