Abstract

PURPOSE:To eliminate a need for a high drive force for delivery of a flat substance and to prevent the occurrence of the double feed of the flat substances by releasing an upper flat substance from support along with delivery of a lower flat substance. CONSTITUTION:A delivery means 1 is provided for delivering a lower postal card A1, positioned at a lowermost part, in a direction extending along the flat surface thereof as a plurality of postal cards A placed and supported in a vertically laminated state. A support means 5 is provided for placing and supporting the edge, situated upper stream of a delivery direction, of an upper postal card A2 positioned above the lower postal card A1, in a state that the edge thereof is separated upward from the lower postal card A1. When the lower postal card A1 is delivered, the upper postal card A2 is dropped from the support means 5 and the dropped upper postal card A2 is delivered as the lower postal card A1. Thus, since a high weight is not exerted on the lower postal card A1 to be delivered, the postal cards are difficult to deliver in a vertically overlapped state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower flat body located at the lowermost part while lowering its own weight of a plurality of flat bodies such as postcards, cards, bills, and sealed letters which are placed and supported in a vertically stacked state. The present invention relates to a flat body feeding device provided with feeding means for feeding in a direction along a flat surface.

[0002]

2. Description of the Related Art In the flat body feeding device,
As shown in FIG. 10, all of the plurality of flat bodies A are placed and supported in a state of being vertically overlapped with each other, and the lower surface of the lower flat body A1 located at the lowermost portion by the weight of the flat bodies A that are vertically stacked. Is pressed against the delivery means 01 such as a delivery roller, and the lower flat body A1 is delivered in a direction along the plane by the drive of the delivery roller 01.

[0003]

Therefore, since the lower surface of the lower flat body A1 to be delivered is strongly pressed against the delivery roller 01, there is a drawback that a large driving force is required to drive the delivery roller 01. When the lower flat body A1 passes the position of the feed roller, the lower surface of the upper flat body A2 located above the lower flat body A1 is immediately pressed against the feed roller 01 to receive the feed action, so that the plurality of flat bodies A Has a drawback that it is easy to be sent out in the state of being piled up and down. The present invention has been made in view of the above circumstances, by devising a support structure for a flat body that is placed and supported in a vertically stacked state, a large driving force is not required for feeding the flat body, and It is an object of the present invention to provide a flat body feeding device in which flat bodies are difficult to be fed in a state of being vertically stacked.

[0004]

The characteristic configuration of the present invention for achieving the above object is to lower a flat lower portion located at the lowermost portion while lowering the plurality of flat bodies mounted and supported in a vertically stacked state by their own weight. A flat body feeding device provided with a feeding means for feeding a body in a direction along the flat plane, wherein an edge of the upper flat body located above the lower flat body in the feed direction is located on the upper side of the lower flat body. Supporting means for mounting and supporting the upper flat body in a state of being separated upward is provided, and the support of the upper flat body by the supporting means is released along with the feeding of the lower flat body by the feeding means.

[0005]

When the lower flat body is sent out, the upper flat body falls from the supporting means, and the dropped upper flat body is sent out as the lower flat body.

[0006]

Therefore, since a large weight does not act on the lower flat body to be sent out, a large driving force is not required for sending out the flat body, and when the lower flat body is sent out, the upper flat body is moved from the supporting means. Since it falls and the upper flat body is sent out as a lower flat body, it is difficult to send it out in a state where the flat bodies are vertically stacked.

【Example】

[First Embodiment] FIGS. 1 to 3 show a plurality of postcards A as an example of a plurality of flat bodies placed and supported in a vertically stacked state.
Lower postcard A1 located at the bottom while lowering
Is provided with a sending means 1 for sending out in a direction along the paper surface,
A postcard sending device for sending a specified number of postcards A by the operation of the sending means 1 is shown.

The sending means 1 restricts the movement of the upper postcard A2 located above the lower postcard A1 in the sending direction, and the left and right which places the lower postcard A1 and sends it to the outside of the restricting means 2. A pair of timing belts 3 and a pulley 4 for driving and rotating the timing belts 3 are provided, and the regulation means 2 is provided with a regulation plate 2B and a resin regulation member 2A. The lower end of the regulation member 2A is located between the left and right timing belts 3.

A support means 5 for supporting and placing the upper postcard A2 located above the lower postcard A1 on the upstream side in the delivery direction of the timing belt 3 in a state where the upper end edge in the delivery direction of the upper postcard A2 is spaced upward from the lower postcard A1. Is provided. The support means 5 is constructed by arranging a large number of idle rollers 6 in an oblique direction at an angle of about 60 ° with respect to the postcard sending direction, and the leading edge of the upper idle roller 6 in the sending direction is below the idle direction. It is arranged in a state of being located immediately above the axis of rotation of the roller 6.

At the lower end of the regulating member 2A, there is formed a recessed portion 2a into which the lower end in the delivery direction of the upper postcard A2 located immediately above the lower postcard A1 is inserted, and the lower end in the delivery direction is this recessed portion. The upper postcard A2 that enters into the 2a and is supported by the idler roller 6 at the edge on the upstream side in the sending direction.
Is the upper postcard A located above the upper postcard A2
It is elastically biased downward by the weight of the group.

When the lower postcard A1 passes through the lower end of the regulating member 2A by driving the timing belt 3, the lower end of the upper postcard A2 in the recessed portion 2a of the regulating member 2A in the feeding direction is on the timing belt 3. As the upper postcard A2 falls, the upper edge of the upper postcard A2 in the delivery direction also comes off the idler roller 6 and falls on the timing bell 13 to be delivered as the lower postcard A1. The postcard A2 has its lower edge in the delivery direction inserted into the recessed portion 2a while the upper edge in the delivery direction is placed on the idler roller 6.

As a discharging means 11 for holding the lower postcard A1 sent out by the timing belt 3 in front of the restricting means 2 in the sending direction and discharging the lower postcard A1 into a predetermined accommodating portion at a speed higher than the sending speed by the timing belt 3. A pair of upper and lower holding rollers 7A and 7B, and a photo sensor 8 as a passage detecting unit that detects passage of the postcard A discharged by the holding rollers 7A and 7B are provided. Of the holding rollers 7A and 7B, the upper holding roller 7B includes
As shown in FIG. 4, as a detecting means for detecting whether or not the postcards A sent by the sending means 1 are vertically overlapped, the thickness of the held postcard A is detected based on the change of the electrostatic capacitance. The multi-feed detection sensor 9 is provided, and based on the detection result of the multi-feed detection sensor 9, the postcard A sent out.
The number of postcards A actually sent out can be counted even if the sheets are vertically overlapped and sent, that is, even if they are double-fed.

Next, the operation of the device controlled by the control means 10 provided in the above-mentioned postcard sending device when the predetermined number of postcards A are sent while counting will be described with reference to FIGS. First, the operator operates a plurality of setting switches (tenn key etc.) provided in the operation section D to set and input data such as the number of postcards to be sent and the price of one postcard [# 1]. When the input of predetermined data is completed and the start switch (not shown) of the device is turned on [# 2],
The control means 10 drives the motor M which drives the sending means 1 and the discharging means 11 <# 3>. As a result, the postcards A, which are placed and supported in the vertically stacked state, are continuously fed one by one by the sending means 1 and discharged by the discharging means 11.

Since the feeding speed of the postcard A of the ejecting means 11 is set to be faster than that of the sending means 1, the postcard A continuously conveyed by this is ejected at high speed by the ejecting means 11 Are separated one by one. The control means 10 counts the number of postcards A separated one by one by the photo sensor 8 provided on the downstream side of the discharging means 11 [# 4], and based on the count value, the sending means 1 When it is determined that the number of the postcards A sent out has reached the set number [# 5], the motor M is stopped [# 8], and the number of the postcards A sent out (it becomes the number set initially) and The total amount is displayed on the display unit H such as a liquid crystal display [# 9].

On the other hand, when the double feeding detection sensor 9 provided immediately after the sending means 1 detects the double feeding of the postcard A and the number thereof [# 6], the corresponding postcard A is detected by the photosensor 8. The count value is corrected by adding the number of double feeds to the count value at the designated timing [# 7].

If, as a result of the correction of the count value, the number of sent-out sheets exceeds the set number of sheets, the "error" display and the excess sheet number data are sent at the stage of the display processing in step [# 9]. And the total amount thereof are displayed on the display means H. With this display, the operator can extract the set number of postcards A by removing the excess number.

[Second Embodiment] FIG. 7 shows a supporting means 5 for supporting and placing the upper postcard A2 located above the lower postcard A1 in a state in which the upper edge of the upper postcard A2 in the delivery direction is spaced upward from the lower postcard A1. Another embodiment of the regulation means 2 is shown, in which the regulation means for regulating the movement of the upper postcard A group toward the lower side in the feeding direction is constituted by one plate 2C, and the supporting means 5 is arranged in the feeding direction of the upper postcard A group.
