Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper industry bundling device for bundling paper sheets such as mail.

In general, this type of paper sheet binding device transports the stacked paper sheets through a conveyance path to a binding section, where the paper sheets are bundled with tape, paper, or wire. It is supposed to be done.

By the way, if the above-mentioned paper products are bunched or have low rigidity and are bundled, the 11 bundles of paper may become bent or damaged if they become jammed, which may hinder subsequent processing or transportation. Ta.

Therefore, the thickness of the above-mentioned stacked paper products was measured in bundle 1,
It has been considered to eliminate the above-mentioned inconvenience by eliminating the paper sheets when the thickness is less than a predetermined thickness, but in this case, the thickness of the laminated paper sheets does not necessarily have to be the same. Since the rigidity is not expressed in the strike sheet, a large amount of the laminated paper 1a- must be removed in consideration of safety, which has the drawback of lowering the passage rate.

The present invention has been made with attention to the above-mentioned circumstances, and its purpose is to improve the passage rate of the paper bundle by detecting and eliminating deviations of the paper bundle from a predetermined state after the bundling is completed. It is an object of the present invention to provide a paper bundling device capable of carrying out the same operations as described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on the drawings. e
! 1 in CL is a conveyance path, and two slide holes 1.4 are bored along the longitudinal direction of the pace 2 of this conveyance path 1, and these slide holes 3° and 4 mm are spaced apart from each other by a predetermined distance. A plurality of feed bins 5..., 6... are provided protrudingly. The feed bins 5..., 6... are moved along the slide holes 3.4 by a drive mechanism (not shown). Furthermore, a bundle section 1 and a removal means 8 are provided adjacent to each other on the side of the conveyance path 10 . The removing means 8 is constituted by an air cylinder 9. On the other hand, on the IJ side of the exclusion means I, as shown in FIG.
is installed. The light emitter 11 emits light when the distance between it and the feeding bin 5 reaches five dimensions, and the light is received by the light receiver 12. When the light receiver 12 receives light, the air cylinder 9 of the removing means is operated via a control circuit (not shown).

Therefore, in the above-described configuration, the pace 2 of the conveyance path 1
Above in Figure 4 (a) l: Paper sheets 1 stacked as shown

4, or by a string 15 as shown in (C) in FIG. 4, or by a sheet 1# as shown in (d) in FIG. Become.

After that, this paper bundle 11 is sent to the feed bin 5 again...
It is conveyed by a predetermined amount by tI..., and its width dimension is detected by the detection means 1o. That is, the light emission of the detection means 1o! When the light emitted from the paper sheet 111 is emitted by the sheet bundle 1r, the sheet bundle 1r has a length L of 1, and is considered to be a good product and is transported as is. On the other hand, if the light emitted from the first light emitter 11 is not blocked by the paper stack 77 and is received by the light receiver 12, the paper stack 11 will be emitted as shown in (Xu ~ (@) in Fig. 5). In this case, the air cylinder 9 is operated to remove the defective paper straw bundle 11 from the conveyance path 1.

As mentioned above, the stacked paper sheets @II... are held in the bundle unit 1.
In order to detect the width of the paper sheets after they are bundled, and to eliminate the deviation if the width dimension deviates from the predetermined size, the number of laminated paper sheets 13 is increased in consideration of safety compared to the conventional method. There is no need to exclude them, and the passage rate can be increased.

In the above-mentioned embodiment, deviations in the external dimensions of the paper bundle 11 are detected, but the present invention is not limited to this. The leaf plexus may also be excluded.

In addition, a detection means for detecting the deviation of the stacked paper sheets @JJ... of the bundle l from a predetermined state is separately provided, and the detected value of this detection means and the predetermined state of the paper leaf bundle 1r after the above-mentioned bundle is completed. It is also possible to calculate the difference between the detected value of the detection means 10 that detects the deviation from the original value, and to exclude the bundles of sheets 12 for which this difference does not meet a predetermined standard.

As described above, the present invention detects deviation from a predetermined state of a bundle of paper sheets bundled by a bundler using a detection means, and removes the bundle of paper sheets detected by the detection means using a removal means. Because of this, there is no need to remove a large number of # layer 11 km of bundle III in consideration of safety as in the past, and the passage rate of the paper bundle can be improved.
