Description

[Detailed description of the invention] (A) Technical field of the invention The invention relates to a form conveyance mechanism, and in particular, after a form on a hopper is fed out and processed in a form processing section,
This invention relates to improvement of a mechanism for transporting forms to a stacker.

(B) Conventional technology and problems
The data is read using OCR, a mark reading device OMR, etc., and the data is processed using a computer. As a form conveyance device used in this case, there is one shown in FIG. That is, the form 2 is stacked on the hopper table 1, and when reading starts, the hopper table 1 rises, and when the top of the form 2 is detected by the sensor a, the rise stops, and the rotation of the pick roller 3 causes the form 2 to move up to the separator section 4.
being sent to. Form 2 in separator section 4
To prevent two or more sheets from being sent in duplicate and feed only one sheet.

The edges of the fed form 2 are instantly aligned along a reference plane (not shown) by an aligner 5, and then sent to a scanning section 6. After the scanning section 6 finishes reading the characters, a serial number is printed by the serial numbering mechanism 7. The printed form 2 passes through the reversing drum 8 and is transferred to the stacker 11 or stacker 1 by the operation of the stacker selection valve 10.
It is divided into 2. Note that sensors located in the middle of the travel route are omitted.

The running path for the form 2 from the hopper table 1 to the scanning section 6 of the above device is generally made up of a lower guide plate and an upper separator to prevent the form 2 from meandering in order to read the form data in the scanning section 6. It has a structure in which it is conveyed by sandwiching it with 4 belts. However, since the running path after the scanning section 6 only needs to transport the forms to the stackers 11 and 12, even in the above device, the running paths 9 and 9' from the reversing drum 8 to the stackers 11 and 12 are as shown in FIG. The upper wire guide 13 and the conveying member (flat belt or roller) 14 are arranged parallel to the form conveying direction (arrow), and the form 2 is conveyed from the conveying member 14.
is conveyed between the upper wire guide 13 and the lower guide plate 15. This is so that the form 2 can be easily taken out in case a trouble occurs on the travel path 9, 9'. Therefore, in this structure, a wire reinforcing plate 16 or joint plates 17 and 18 are provided between the wires.

However, the form 2 is easily deformed due to being handled manually, especially at the corners, and when the form 2 moves in the direction of the arrow on the conveyance paths 9 and 9', it floats up due to wind pressure, etc. When the corner comes off from the upper wire guide 13, the wire reinforcing plate 16,
Otherwise, there were problems such as hitting the joint plate 17 and causing trouble (jam).

(C) Purpose of the invention In view of the above-mentioned drawbacks of the prior art, the object of the present invention is to provide a form conveyance mechanism that does not cause any trouble even if the form is deformed.

(D) Structure of the invention According to the invention, this object is achieved by providing a form conveyance mechanism characterized in that the upper guide wire is arranged at an angle θ with respect to the form conveyance direction. It will be achieved.

(E) Example of implementation of the idea Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows one embodiment of the form conveyance mechanism of the present invention, with A being a plan view and B being a side view.

In the figure, the wire guides A, B, C, and D are arranged so as to be inclined at an angle θ with respect to the document conveyance direction so that they always escape in the direction from which the document 2 exits. In this example, a wire with a wire diameter of 3 mmφ is used for approximately 5
Tilt the wire guides A, B, at a pitch of 60 to 80 mm.
C and D were constructed.

In the state shown in the figure, the corner a of form 2 is
is holding down. As Form 2 progresses, Form 2
There is a possibility that the corner a of the sheet may come off the wire guide C and float up (for example, due to curling of the form 2 or due to lifting force during movement). However, form 2
As the process progresses, the corner a of the form 2 is pressed down by the wire guide B to prevent it from floating up. By repeating this one after another, jamming of the form due to lifting can be prevented and stable conveyance can be achieved.

In addition, when holding the form using a wire guide,
It is sufficient if the rear end of the form 2 is held down by the wire guide C when the leading edge of the form 2 comes off the wire guide C. Therefore, if the inclination angle of the wire guide with respect to the form conveyance direction is too large, the pitch of the wire guide will be narrowed, so it is better to make it as small as possible.

(F) Effect of the invention As explained in the above embodiments, by creating a form transport mechanism in which the upper guide wire is arranged at an angle θ with respect to the form transport direction, the form can be transported even if the form is deformed. There will be no trouble on the way.
