DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collecting apparatus capable of collecting sheets compactly.

[0002]

2. Description of the Related Art In recent years, in an image recording apparatus for plate making,
Since the developing step can be omitted, a composite film in which a release sheet is adhered to a base sheet on which a coloring material is formed has been used. When a composite film having a predetermined length is wound around an exposure drum and exposed, the color material portion having image information is fixed on the base sheet side, and the base sheet on which the image is recorded, that is, the image forming sheet is formed by peeling off the release sheet. can get.

[0003] Not limited to the release sheet of the composite film,
For example, also in DDCP (Digital Direct Color Puller), there are ink sheets that become unnecessary after exposure, and these unnecessary sheets are recovered and discarded after being peeled off from the base sheet side.

To collect unnecessary sheets, a collection area such as a trash can is usually provided outside a processing apparatus such as an image recording apparatus, and unnecessary sheets conveyed from the processing apparatus are dropped there.
Collected. Further, it has been attempted to rotatably support a ring-shaped guide, convey an unnecessary sheet inside the guide while rotating the guide, and collect the unnecessary sheet.

[0005]

However, providing a collection area such as a trash can requires a space outside the processing apparatus, which increases the installation space for the apparatus. In addition, since the unnecessary sheets are simply dropped, the unnecessary sheets are bulky in the collection area. Therefore, in order to increase the collection amount, the collection area must be enlarged accordingly. Further, in the method of collecting while winding inside the ring-shaped guide, troubles such as jams are apt to occur at the time of collection, and the collection amount is limited to several sheets, which is not practical.

The present invention has been made in view of such a problem, and provides a sheet collecting apparatus capable of collecting a large number of sheets conveyed discontinuously and compactly.

[0007]

According to the present invention, there is provided a sheet collecting apparatus, comprising: holding means for winding and holding a transport support material having an adhesive layer formed on one surface; and rewinding the transport support material from the support means. A winding unit that winds while being wound, between the holding unit and the winding unit, is disposed on a moving path of the transport support member, and the sheet transported from the upstream side with respect to the adhesive layer of the transport support material. And crimping means for crimping.

[0008] According to this recovery device, the sheet conveyed from the upstream side is pressed against the adhesive layer of the transfer support material by the pressing means, and then the sheet is adhered and fixed to the transfer support material. Together with the winding means, a large number of sheets conveyed discontinuously can be reliably and stably compactly wound and collected,
In addition, disposal of the collected sheet can be easily performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an unnecessary sheet collecting apparatus according to an embodiment includes a pair of upper and lower conveying rollers 1 which sandwiches an unnecessary sheet 1 between roller opposing portions and sends the sheet to a downstream side.
0, 10A (conveying means) and the conveying rollers 10, 10
A pair of feed rollers 20 and 20A provided on the downstream side of the transport guide 12 via the transport guide 12, and holding means 40 for rewindably holding the transport support material 30A wound up in a roll shape.
And the roll-shaped transport support material 3 held by the holding means 40
There is provided a winding means 50 for rewinding the unnecessary sheet 1 via the transport support member 30 which is rewound from 0A and wound around the lower feed roller 20. The feed rollers 20, 20A are
The transport support 30 wound around the lower feed roller 20
The unnecessary sheet 1 is carried out together with the transport support member 30 to the take-up means 50 in a state where the unnecessary sheet 1 is sandwiched via the support member 30 and the lower surface of the unnecessary sheet 1 is supported by the transport support member 30.

One (lower in the illustrated example) of the transport rollers 10 and 10A has a fixed rotating shaft so that the unnecessary sheet 1 can be sandwiched between the outer rollers of the transport rollers 10 and 10A. The transport roller 10A of which the rotation axis is movable in the plane shown in the drawing with respect to the fixed transport roller 10
The side is biased by a spring or its own weight. The fixed-side transport roller 10 is driven by a drive motor so as to be able to stop rotation. In this case, the other transport roller 10A is used for the unnecessary sheet 1.
And is driven to rotate.

In order to transport the unnecessary sheet 1 more reliably, the transport roller 10 on the driving side is moved from the transport roller 10 on the driven side.
A gear or a belt conduction member may be attached to both transport rollers 10 and 10A so that rotation is transmitted to 0A. Further, a lining layer may be formed on the outer peripheral surfaces of the transport rollers 10 and 10A with a material such as rubber having a large coefficient of friction.
The feed rollers 20, 20A are also
This is the same configuration as A.

As the transport support member 30, a tape,
A long band-shaped material such as a thread or a film-shaped wrap material having an adhesive layer formed on one surface thereof can be used. For a material having a small width, both ends of the unnecessary sheet 1 are supported, preferably further at the center. About two or three are used in parallel in the transport direction. On the other hand, when the width of the transport support member 30 is about half the width of the unnecessary sheet 1, one piece may be used so as to support the central portion of the unnecessary sheet 1.

When an adhesive tape is used as the transport support member 30, it is of course wrapped around one of the feed rollers 20, 20A so that the adhesive surface is attached to the unnecessary sheet 1. When an adhesive tape is used, there is an advantage that the transport state is stable and winding is extremely stable regardless of the transport direction.

The holding means 40 only needs to have a mounting shaft 41 capable of freely and rotatably mounting a paper tube, which is a core of the transport supporting material 30A wound in a roll shape. Further, the winding means 50 may be provided with a winding shaft 51 which is connected to an appropriate drive source such as a torque motor and is capable of controlling torque and capable of stopping rotation. By the winding shaft 51, the transport support member 30 or the transport support member 30 and the unnecessary sheet 1 supported by the transport support member 30 are wound according to the amount of feeding from the feed rollers 20, 20A. Usually, at the time of winding, a paper tube is attached to the winding shaft 51 as a winding core. For example, if a used paper tube of a roll film for image recording is used as the paper tube, the whole paper tube can be discarded as it is, and a dedicated paper tube for winding is not required.

The operation of the unnecessary sheet collecting apparatus will be described.

Until the unnecessary sheet 1 is transported by the transport rollers 10 and 10A and arrives at a position near the upstream side of the feed rollers 20 and 20A, the feed rollers 20 and 20A stand by with the transport support material 30 wound thereon. are doing. The leading end of the transport support 30 wound around the lower feed roller 20 is fixed to a winding core (paper tube) attached to a winding shaft 51 of a winding unit 50, and the transport support 30 is wound. It can be wound by the means 50.

Then, as shown in FIG.
Arrives at a predetermined position, the feed rollers 20, 20A and the winding means 50 are rotated, and the transport support material 30 is held by the holding means 4.
It is pulled out from 0 and wound up by the winding device 50. The arrival of the unnecessary sheet 1 is detected by a detector such as a photo sensor, and the drive motors of the feed rollers 10 and 10A and the winding device 50 are controlled by the detection signal.

The leading ends of the unnecessary sheets 1 are feed rollers 20 and 2
2A, the unnecessary sheet 1 is conveyed to the take-up device 50 with the lower surface thereof being supported by the conveying support 30 as shown in FIG. It is conveyed at the same speed together with 30, and is smoothly wound up by the winding device 50 as shown in FIG.

After the unnecessary sheet 1 has been wound, the driving of the feed rollers 10, 10A and the winding device 50 is stopped, and the apparatus stands by in that state until the next unnecessary sheet 1 is conveyed.
The drive stop timing is determined by detecting that the unnecessary sheet 1 has been discharged from the feed rollers 10 and 10A by the detector, or by controlling the drive motor based on the elapsed time from the start of rotation of the feed rollers 10 and 10A. Good.

The unnecessary sheet 1 wound up by the winding means 50 via the transport support member 30 can be removed from the winding shaft 51 and discarded as it has a predetermined winding diameter. According to this collection device, a large number of unnecessary sheets 1 that are conveyed discontinuously can be sequentially wound up via the conveyance support member 30, so that the unnecessary sheets 1 can be reliably and easily and compactly wound up. It is possible to easily collect and dispose of the unnecessary sheet 1 by using the release sheet 1.
There is no need for a large space area for collecting waste.

It is needless to say that the present invention is not limited to the above-described embodiment.
Various modifications and embodiments can be made. When a transport support having a width shorter than the width of the sheet to be collected is used, when the adhesive is fixed to the transport support outside the necessary area of the sheet (such as an image forming area in a photographic film), the winding Since the necessary area of the sheet is not impaired by taking and collecting, the present invention can also be applied to collecting sheets other than unnecessary sheets.

[0022]

According to the sheet collecting apparatus of the present invention, the discontinuously conveyed sheets can be sequentially wound through the conveying support, so that a large number of sheets can be reliably and stably compacted. Can be recovered.
