Abstract

PURPOSE:To prevent the surface of a transfer roller from attachment of ink typed on a slip for improving reliability by providing a means for preventing the transfer roller disposed on a typed surface from the attachment of ink. CONSTITUTION:A business slip 7 is taken out of a receiver box 1 and transferred through a sprocket 2. After the slip is typed on one surface the business information by a typing device 3, it is drawn out by transfer rollers 13a, 13b and transferred in the direction A. And when the leading end of the slip 7 is pinched by transfer rollers 5, 6, the roller 5 has the periphery wound by a Teflon tape 14 so that a slipping condition is produced between the slip and the roller when the roller 5 is rotated to transfer the slip 7, and a force sufficient to transfer the slip does not act on the slip 7. And when a portion of the roller 5 around which the Teflon tape 14 is not wound contacts the slip, the rollers transfer the slip while pinching the slip without producing the slip. Since the surface around which the Teflon tape 14 is wound repels ink, the surface of the slip is not stained.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a conveyance device equipped with a printing device.

[Technical background of the invention and its problems] Conventionally, automatic transaction devices installed in banks, etc., have a function of issuing documents containing transaction information to users of the device. I am prepared. Normally, a unit called a slip printer is installed to issue the N type, and two sheets of slip paper are usually used. There are two types of slip paper: a receipt slip and a transaction slip, and transaction information is printed out using a printing device provided along the conveyance path of the slip paper.

Of the slips printed in this manner, the slips are wound up on a winding device and stored, while the transaction slips are cut by a cutting roller for each transaction and then handed to the user. However, according to the above-mentioned device, ink adheres to the surface of the transaction slip handed to the user when it is printed, and in that state it is conveyed by the cutting and conveying rollers etc. installed in this device. ing.

Since the transaction slip is conveyed with ink still attached to it by the conveyance roller, the ink adheres to the surface of the conveyance roller, and the conveyance roller rotates again to convey the transaction document. The ink that adhered to the surface of the conveyance roller adheres to this transaction slip, causing it to appear as if it is printed in a place where it should not be printed, causing anxiety to the user who received this transaction slip. A problem has arisen in that the reliability of the automatic transaction device is lost.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a conveying device in which what is printed on a slip does not adhere to the surface of the conveying roller that conveys the slip. .

[Summary of the Invention] The outline of the present invention for achieving the above object is as follows: Printing devices are sequentially arranged on a conveyance path of paper sheets, and tension is applied to the paper sheets in order to cut the paper sheets at regular intervals. In a conveyance device that faces a cutting device having at least one conveyance roller, the ink printed on the sheet by the printing device is applied to the conveyance roller disposed on the printed surface. In order to prevent ink from adhering, this conveyance roller is provided with means for preventing ink from adhering. [
Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of an automatic transaction device which is a conveyance device of the present invention. In the figure, the reference numeral 1 is a slip storage box for storing slips made of two folded paper sheets, and is designed to store slips for, for example, 400 transactions. This slip has perforations for each transaction, and the lower slip (copy slip) in the figure of the two stacked slips is made of thermal paper.

The slips stored in this slip storage box 1 are conveyed via a sprocket 2 provided above this slip storage box 1 to a printing device 3 installed above and to the left of this sprocket 2 in the figure. Transaction information is printed.

A slip separator 12 is provided downstream of the printing device 3 to separate the two stacked slips. This slip separator 1
2, the transaction slip 7 is transported in the direction of the arrow B, and the receipt slip is transported in the direction of the arrow B.
The slip is discharged from a slip outlet (not shown) and handed to the user, and the slip is wound up by a winding device 8 and stored as a copy.

Next, the subsequent stage of the slip separator 12, particularly the step in which the transaction slip 7 is discharged from the discharge port, will be described in detail.

As mentioned above, the transaction slip 7 among the two stacked slips is transferred to the conveyor roller 1 provided at the rear stage of the slip separator 12.
3a and 13b, and is conveyed while being simultaneously applied with a tensile force by conveyance rollers 5 and 6 in the figure. In order to obtain this tensile force, in this embodiment, the rotational speed of the conveyance rollers 5 and 6 is set faster than that of the conveyance rollers 13a and 13b.

At this time, since the slip is provided with perforations to cut it at regular intervals, the perforations are the conveyance roller 13a,
When reaching the part of the cutting roller 4 provided after 13b, the central diameter of the cutting roller 4 is larger than that of the end of the roller, so the concentrated force is applied to the center of the slip.
The tensile force will be applied and it will be cut at the perforation.

In this way, a transaction slip for one transaction is created.

However, when characters, for example, printed by the printing device 3, are pulled by the conveyance rollers 5 and 6, the conveyance roller 5 in contact with the printed surface obtains a tensile and clamping force, so that the contact resistance of the surface is large. For example, since rubber is used, there was a problem that the printing ink would be transferred to the surface of this conveyance roller, and that ink would be transferred to the next conveyed slip, but the present invention solves the problem. In order to solve this problem, the roller is configured as shown in FIG. 2, which is a perspective view of the roller.

In the same figure, the conveyance roller has a Teflon tape 14 wound around its surface as an adhesion prevention means, and a non-water repellent layer is further applied at a portion having an interval of about 3 mm parallel to the rotational axis direction of the conveyance roller. ).

The operation of the conveying roller configured in this way will be explained with reference to FIGS. 3(a) and 3(b).

FIGS. 3(a) and 3(b) are explanatory views of the operation of the conveyance roller of the present invention, in which a Teflon tape 14, which serves as an adhesion prevention means, is wound around the surface of the conveyance roller.

The slip is taken out and conveyed from the storage box 1 via the sprocket 2, transaction information is printed on one side by the printing device 3, and then fed and conveyed by conveying rollers 13a and 13b, and the transaction slip 7 is conveyed in the six directions of the arrows. be done. (See Fig. 1) The tip of this transaction slip 7 is connected to the conveyor rollers 5 and 6.
Since the conveyance roller 5 of the present invention has Teflon tape 14 wrapped around it, even when the conveyance roller 5 rotates to convey the transaction slip 7, there is no space between it and the transaction slip 7. A slipping condition occurs, and the force sufficient to convey the transaction slip 7 does not act on it (see Figure 3 (a)).
. When the unwound portion of the Teflon tape 14 comes into contact with the slip, the slip is held and conveyed without slipping. (At this time, the transaction slip 7 for one transaction is cut.) In this way, the transaction slip 7 for one transaction is conveyed. For this reason, the surface around which the Teflon tape 14 is wrapped comes into contact with the printing surface of the transaction slip 7, but since it has the property of repelling the printing ink, the surface around which the Teflon tape 14 is wound is in contact with the printing surface of the transaction slip 7. Since the interval between the Teflon tape 14 and the Teflon tape 14 is set so as to match the length direction of one transaction slip, the printed part does not come into contact with anything other than the Teflon tape 14, so that the surface of the slip is not soiled.

The present invention is not limited to the one embodiment described above, and various modifications can be made within the scope of the gist of the present invention.

4(a), (b), and (c) show external perspective views of modified examples of the present invention. For example, as shown in FIG. 4(a), a portion 14a where the Teflon tape 14 is not wound. may be flush with the outer periphery of the Teflon tape 14 (in the above embodiment, it is concave).Also, as shown in FIG. However, as shown in the figure, the adhesion prevention means may be wrapped around the intermittent shape.
This adhesion prevention means may be divided into two or more parts as shown in FIG. 2(C). In the above embodiment, Teflon tape 14 was used as the adhesion prevention means, but the present invention is not limited to this, and any material that repels printing ink can be used.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a conveyance device in which what is printed on a slip does not adhere to the surface of the conveyance roller that conveys the slip.
