Abstract

PURPOSE:To perform smooth and normal posture change without bending and without change in speed in the conveying direction when a sheet of paper is translocated from a first conveying passage by forming a posture changing mechanism with plural belt trains or roller trains and plural driven rotary bodies. CONSTITUTION:A sheet of paper 5 which has been conveyend on a first conveying passage 1 at a velocity V is fed being interposed in between plural belt trains 3a-3c and plural driven rotary bodies 4a-4n, and delivered to a second conveying passage 2. In this case, a turning force is applied to the sheet of paper 5 due to difference in speeds among the belt trains 3a-3c, finally delivering the paper 5 to the second conveying passage 2 in the posture of the paper 5' which is 90 deg. rotated from the posture of the paper 5 on the first conveying passage 1 and, after that, the paper 5 is conveyed in this posture at the velocity V. Since the speed in the conveying direction when the sheet of paper 5 is translocated is not fundamentally varied unlike the conventional case where a sheet of paper is rotated at a speed zero, even an object such as a piece of mail having a lopsided content can undergo smooth and normal posture change without being bent.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a mechanism for changing the conveyance posture of paper sheets during the course of conveyance when automatically conveying and processing paper products such as (industrial application field).

(Prior art) In the paper sheet transport device ayc in this building, the paper sheets are rotated, for example, 90 degrees within a horizontal transport plane during transport, and in this state are again transported in the same direction vc@. may occur. The conventional mechanism for changing the conveyance posture of one paper sheet is shown in Fig. 4 (a).
), (b), and (c), a first conical rotating body 8 is installed in the middle of the conveyance path 7 and is rotationally driven by a drive source (not shown) in the same direction as the conveyance direction; The second conical rotating body 9 is placed between the conveying path 7t and pressed against the first conical rotating body 8 so that their conical generatrices are in contact with each other, and is driven to rotate. When the paper sheet 5Q) is fed through the conveyance path 7 in the direction of the arrow VcWi in a vertically elongated posture and its leading edge 5a is sandwiched between the double-sided conical rotating bodies 8 and 9, the paper sheet 5 is moved by the rotating bodies 8. To the larger radius of 9, that is, to the bottom side of the rotating body, turn 90 degrees as shown by arrow B.
The paper sheet 5' converted to 0' is conveyed again in the same direction as before.

(Problems to be Solved by the Invention) In the conventional posture changing mechanism, for example, when a paper sheet such as a mail is sent, the contents 51 are transferred to the envelope 52 as shown in FIG. 5(a) IC.
If it is located on the end (bottom) side of the mail item 5.
0 is sandwiched and rotated by the conical rotating bodies 8 and 9 in FIG. Since rotational force is applied to the mailpiece 50 by .9, at the beginning of one rotation, only the tip end 50a of the mailpiece 50 is held between the two conical rotating bodies 8°9, receives the rotational force, and the end of the mailpiece 50 50bllll is delayed in its rotation due to the weight of the contents 51, and when it passes through the posture change mechanism, it rotates as shown in Fig. 5(b) +F
- It had the disadvantage of being bent as shown.

(Means for Solving the Problems) In order to solve the above-mentioned drawbacks, the attitude changing mechanism of the present invention uses a plurality of conveyor belt rows that have different speeds and are arranged in parallel in the order of speed gradients in the middle of the conveyance path. and a plurality of rotating bodies that are driven to rotate in contact with the belt row.

(Example) Next, one embodiment of the present invention will be explained with reference to the drawings.

FIG. 1(a) is a perspective view of a sheet conveying attitude changing mechanism according to an uninvented embodiment, and FIG. 1(b) is a plan view of the JJM structure of FIG. 1(a) during attitude changing operation. . FIG. 1(C) is a side view of FIG. 1(a). Figure 1 (a) to (c)
In an IC, a first conveyance path 1 and a second conveyance path 2, which both rotate at the same speed v1, are arranged apart from each other in the direction of the conveyance paths, and a plurality of belt rows 3 are arranged between the conveyance paths 1.2. a,
3be3C extend in the yc transport direction and are arranged in parallel to each other. The plurality of belt rows 3a to 3C each have a different conveyance speed, and are driven by a drive source 9 (not shown) so that the speed increases sequentially from one side of the conveyance path to the other side. Specifically, they are arranged in parallel at equal intervals in order of speed gradient so that they are driven by belt rotation. Further, above each belt row 31 to 3C, a plurality of driven rotating bodies 4a to 4n (not shown) are rotatably supported in contact with the belt row. These rotating bodies 4a to 4n rotate at speeds corresponding to the belt speeds of the belt rows 3a to 3C with which they are in contact.

Referring to FIG. 1(b), the paper sheets 5 conveyed from the first conveyance path IK at a speed V are transported by a plurality of belt rows 3a to
3C and a plurality of driven rotating bodies 4a to 4n, and are sent to the second conveyance path 2, but at that time, due to the speed difference between the belt rows 3a to 3C, the paper sheets 5 are Rotational force is applied, and in Himeji, the paper sheet position on the first conveyance path 1 is changed to 9.
The paper sheet 5' rotated 0' takes the posture and moves to the second conveyance path 2.
Vc passed.

Thereafter, it is conveyed at a speed V on the second conveyance path 2 in this posture.

In the embodiment of FIGS. 1(a) to (e), belt rows 3a to 3
Although the present invention does not necessarily require such an example (as shown, the interval and speed may be set in any combination as long as the belt interval Ts - T - Tz and the speed gradient are proportional. In the embodiment shown in FIG. 3(a), each belt row was composed of the endless conveyor belt 3.
As shown in FIG. 6(b), the supernatant may be configured as a roller row 6A including a plurality of rollers 6a to 6nK each driven at a constant speed by a drive source (not shown).

(Effects of the Invention) As described above, according to the present invention, an attitude changing mechanism is configured from a first conveyance path to a plurality of belt rows or roller rows and a plurality of driven rotating bodies.

When the paper sheet transfers to the attitude change mechanism, 'f! The speed in the conveying direction basically does not change, and unlike conventional methods, the speed in the vc conveying direction is once Ovc and then the paper is swung around to give rotational force. It has the effect of smoothly and royally changing posture without bending even something like a lopsided piece of mail.
