Abstract

PURPOSE:To take up sheet separately by attracting paper sheets which are delivered by a delivery means with an attractive belt, operating the delivery means reversely for stopping a part of paper sheets at a stopper to be stayed, and taking up a few pieces of sheets with the attractive belt. CONSTITUTION:If a few pieces of mail 9 are delivered with a delivery belt 2, the mail 9 are attracted by an attractive belt 6, and separated into one or two with a detection lever 5 to be taken up. If a lot of pieces of mail 9 are delivered, the mail 9 presses the detection lever 5 for detecting a full condition. At this time, the delivery belt 2 is operated reversely. Then a part of the mail 9 are stopped at a stopper 10 and stay at the front part of the attractive belt 6, and the rest mail return to be separated. Then the staying mail 9 are advanced by a few pieces (2-3 pieces) in a unit with the attractive belt 6, and taken up in a separated condition into 1 or 2 pieces by the detection lever 5.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a paper sheet conveying device that is provided in, for example, an automatic mail processing device and that arranges mail items and conveys them to a stamping machine. Regarding.

(Prior Art) This type of conveyance device is equipped with a conveyor belt on which mail is placed and conveyed, and one or more mails are placed on the discharge end side of the conveyor belt.
A suction vest for taking out mail in two pieces and a guide for guiding the mail to this suction belt are provided.

Furthermore, guide rails are provided on both sides of the conveyor belt.

Thus, the mail is placed on the conveyor belt, and when the conveyor belt runs, it is conveyed along the guide rails.

By this conveyance, the mail reaches the discharge end of the conveyor belt and is guided by the guide toward the suction belt.

The mail guided to the suction belt side is sucked by the suction belt, smoothed into 1.2 pieces and taken out, and conveyed to the sorting and stamping machine.

(Problem to be Solved by the Invention) However, in the past, the above-mentioned guide rails were arranged in parallel at equal intervals throughout and the mail was conveyed as it was to the suction belt side, which resulted in a large amount of mail. When the mail is transported, there is a problem in that the suction belt cannot remove the mail in units of one or two, and jams occur.

Therefore, an object of the present invention is to provide a paper sheet processing device that can reliably take out paper sheets in units of one or two sheets even when a large amount of paper sheets is sent in. purpose.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes a conveying means for conveying paper sheets in forward and reverse directions, and a take-out device for taking out filtered paper sheets conveyed by this conveying means. means for causing the conveying means to travel in the opposite direction when the paper sheets conveyed by the conveying means are conveyed to a position facing the take-out means; and the means for causing the conveying means to travel in the opposite direction. and a stopper that causes only a portion of the paper sheets to come into contact with and remain when the paper sheets are removed, and the paper sheets that contact the stopper and remain are dispersed into small units and taken out by the take-out means. That is.

(Function) When a large amount of paper sheets is fed in, the paper sheets are conveyed in the opposite direction and brought into contact with the stopper to form a small number of sheets.From this state, the paper sheets are leveled and taken out.

(Example) The present invention will be described below with reference to an example shown in the drawings.

FIG. 1 shows a mail processing apparatus, in which reference numeral 1 denotes a drive roller that rotates in forward and reverse directions. A conveyor belt 2 as a conveyor means is passed around the drive roller 1.

``Furthermore, guide rails 3.4 are disposed on both sides of the conveyor belt 2 with an interval of 40+IIm.

Furthermore, a detection lever 5 as a detection means is provided on the discharge end side of the conveyor belt 2. This detection lever 5
is made of a flexible material, for example metal, and as described later, when a large number of paper sheets presses the detection lever 5, it bends under the load.

As a result of this deflection, a microswitch (not shown) is pressed to detect whether the container is full. In this embodiment, when the detection lever 5 is pressed for 10 to 15 sheets, it is detected as full.

Further, a suction belt 6 as a take-out means is provided opposite to the detection lever 5, and this suction belt 6 has a large number of suction holes a... bored therein.

The suction heald 6 is stretched between rollers 7 and 7.

A suction chamber 8 is provided on the back side of the suction belt 6, and the suction chamber 8 allows the suction holes 16a to
Air is suctioned from . . . and the mail 9 is suctioned onto the suction belt 6.

By the way, the tip of the guide rail 3 has a width dimension a,
That is, a stopper 10 is formed with a dimension (5■■) corresponding to the width dimension of a small number (2 to 3 pieces) of mail 9, and the suction belt 6 is connected to this stopper 10.

When the drive roller 1 is rotated in the direction of the arrow a (forward direction), the conveyance heald 2 is moved forward, and the mail 9 is conveyed.

At this time, if there are 9 or 2 or 3 pieces of mail,
... are attracted to the suction belt 6, smoothed into one or two sheets at a time, and taken out one by one and sent.

Further, when there are many pieces of mail 9, as shown in FIG. 2, the mail 9 or detection lever 5 is strongly pressed to detect whether the mail 9 is full or not. As a result of this detection, the drive motor 1 is rotated in the opposite direction as shown in FIG. 1, and the mail 9 is conveyed in the opposite direction as shown in FIG. The rest rests in contact with the stopper 10 of the guide rail 3, and the rest is conveyed rearward along the guide rail 3.

Thereafter, as shown in FIG. 4, the conveyor heald 2 and the suction belt 6 are run in the direction of the arrow, and a small number (2 to 3) of mail pieces 9 are moved forward and come into contact with the detection lever 5. , they are smoothed into two copies and taken out one by one.

As mentioned above, when a large number of mail items 9 are sent in, the mail items 9 are sent backwards, a portion of which is brought into contact with the stopper 10 to reduce the number of pieces to a smaller number of pieces, and then sent to the suction belt 6. The belt 6 can reliably level the mail and take it out.

[Effects of the Invention] As explained above, according to the present invention, even if a large number of mail items are sent, they can be reliably leveled and taken out, and jams of paper sheets can be reliably prevented. .
