JPH02215638A - Extreme end inverting mechanism for paper sheet or the like - Google Patents

Abstract

PURPOSE:To miniaturize an extreme end inverting mechanism by rotating a paper sheet or the like about 180 deg. with a vane wheel, stopping rotation of the extreme end of the paper sheet with an accumulating plate, and scraping out the paper sheet in the reverse direction against rotation of the vane wheel with a sweeper. CONSTITUTION:A paper sheet or the like 8 carried in the A direction with carrying rollers 2a, 2b, is brought into between the vanes 3a, 3b of a rotating vane wheel 3 in the B direction and rotated. The front end of the paper sheet or the like 8 is stopped with an accumulating plate 4 on the position at rotation of about 180 deg. of the vane wheel 3, and only the rear end is continued to rotate. When the rear end is approached to the accumulating plate 4, it is struck downwards with an elastic sweeper 5 rotating in the C direction, further pulled in the reverse direction against the A direction, and the extreme end of the paper sheet or the like 8 is inverted and carried. Hence, miniaturization of the device can be attained with simple constitution and the process time can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet processing mechanism, and particularly to a tip reversing mechanism for the paper industry.

[Conventional technology]

Conventionally, this type of paper sheet leading edge reversing mechanism has stopped the paper sheet on a turntable, rotated it 180 degrees, and sent it out.

[Problem to be solved by the invention]

The conventional paper sheet tip reversal mechanism described above was stopped on a turntable and rotated "iso" to feed it.
There are disadvantages in that the processing time is long and the mechanism is complicated.

An object of the present invention is to provide a mechanism for reversing the leading edge of paper sheets, which solves the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, the paper sheet leading edge reversing mechanism according to the present invention includes an impeller that rotates the paper sheet by sandwiching it between blades, and a stacking plate that stops the rotation of the paper sheet leading edge. , has a sweeper that rotates in the opposite direction to the impeller,
The paper sheets are rotated approximately 180'' by the impeller, the rotation of the leading edge of the paper sheets is stopped by the accumulating plate, and the paper sheets are scraped out by the sweeper in the opposite direction to the rotation direction of the impeller. It has the ability to reverse the tip.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

1(a) and 1(b) are a plan view and a side view of an embodiment of the present invention. In FIG. 1, la and lb are conveyor belts, and 2a and 2b are conveyor rollers. Reference numeral 3 designates an impeller that rotates the paper sheet 8 by sandwiching it between blades 3as 3a, 4 a stacking plate that stops the rotation of the tip of the paper sheet 8, and 5 a sweeper that rotates in the opposite direction to the impeller 3.

6a and 6b are conveyance rollers, and 7a and 7b are conveyance belts.

Next, the operation will be explained with reference to FIGS. 2, 3, 4, and 5.

Paper sheets 8 conveyed in the A direction by the conveyor belts ia, lb and the conveyor rollers 2a, 2b enter between the blades 3a of the impeller 3 rotating in the B direction (Fig. 2).
.

The leading edge of one sheet 8 is stopped by the stacking plate 4, which is installed at a position where the leading edge of the sheet 8 has rotated approximately 180 degrees, and only the trailing edge continues to rotate (FIG. 3). When the rear end of the paper sheet 8 approaches the stacking plate 4, it is knocked downward by a sweeper 5 made of an elastic material such as rubber, which rotates in the C direction, and is further pulled in the C direction (Fig. 4). .

The paper sheets 8 pulled in the C direction by the sweeper 5 are further transferred to transport rollers 6a, 6b and a transport belt 7a.

7b, it is transported in the direction C (FIG. 5).

As mentioned above, 1 impeller 3. Accumulation plate 4. Sweeper 5
By using this, the leading edge of the paper sheet 8 can be reversed.

〔Effect of the invention〕

As explained above, the present invention rotates the traveling direction of paper sheets by 180 degrees using an impeller, and then strikes the rear end of the paper sheets with a rotating sweeper to scrape them out in the opposite direction to the rotation direction of the impeller. By reversing the leading edge of a sheet, there are effects such as miniaturization of the mechanism for reversing the leading edge of a single sheet, shortening of operation processing time, and reduction of operational errors.

FIG. 1(a) is a plan view showing one embodiment of the present invention, FIG. 1(b)
2 is a side view of the same side, and FIGS. 2, 3, 4, and 5 are explanatory views of the operation of the present invention. la, lb, 7a, 7b - conveyance belts 2a, 2b, 6a, 6b - conveyance rollers 3...impeller 4...accumulation plate 8...paper sheets 3a...blade 5...sweeper
