Abstract

PURPOSE:To prevent a device being damaged by a foreign mater, such as a clip attached to a matter to be fed, by controlling the operation of feed rollers by a signal given by electrical contact members arranged on a guide surface located up stream from the feed rollers to detect a foreign matter. CONSTITUTION:A sheet material 11 is fed onto a guide slope, 5 and then is fed into a device by rollers 6 to 9 which are driven by a reversible geared motor 1. Electrical contact members are arranged on the surface of the guide slope 5, over the entire width thereof and are connected alternately to terminals A and B by conductors in the same plane. The terminals A and B are connected to the above motor 1 through a control unit 2 which receives power supply from a plug 3. In case a sheet 11 carrying a foreign matter 12, such as a clip, is fed onto the guide slope 5, the foreign matter 12 comes into contact with the adjacent contact members arranged on the guide slope 5, whereby a signal is given to stop the motor 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device, and particularly to a feeding port of an office machine or the like that performs image processing, sorting, etc. on sheets of paper, plastic, or the like.

BACKGROUND ART Conventionally, a feeding port for feeding a sheet-like object is composed of a guide surface that is sloped like a slide and a feed roller downstream of the guide surface in order to make it easier to feed the sheet-like object. Sheet-like objects are conveyed into the device by this feed roller, but in general, sheet-like objects are often bound with clips, insect pins, etc. for convenience, and these sheet-like objects are fed one by one from the feed port. For this reason, clips, insect pins, etc. are removed near the feeding port, but sometimes the sheet-like object is fed without being removed, which may damage the feeding roller or damage the device. Another idea was to place a ferromagnetic material on the slide and attach clips, insect pins, etc. to the slide to prevent it from being fed into the rollers, but a clip was attached to the rear part of the sheet-like object being fed. If insect pins or the like are fixed, even with this method, damage to the sheet-like object or damage to the device or feed roller cannot be avoided.

In order to solve the above-mentioned problems, the present invention is a device that detects and transmits the presence of clips, insect pins, etc. in the feeding kite section and controls the feeding drive section so that these do not accidentally enter the device. The present invention provides a feeding device comprising:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure and effects of the present invention will be described below with reference to drawings showing one implementation of the present invention.

FIG. 1 is a perspective view showing the configuration of a feeding section of a feeding device according to the present invention, in which a sheet-like object to be processed is placed from the front side of the figure by an inclined guide 5 equipped with an electric contact member, which is a feature of the present invention. sent to. Adjacent to the downstream side of the inclined kite 5, a drive roller 7 driven by the reversible gear moke 1, a driven roller 6 disposed opposite thereto, and driven in conjunction with the drive roller 7 via a power transmission member 10. The sheet-like object is carried into the apparatus by a drive roller 8 and a driven roller 9 disposed opposite thereto.

In the figure, one embodiment of the electrical contact member disposed on the inclined guide has contact conductors from both terminals A and B arranged opposite each other alternately in a plane along the entire width of the guide surface as shown in the figure. The terminals A and B are connected to the geared motor l via a control unit 2 that receives power from a plug 3. Note that 4 indicates a reset switch.

To describe the operation of the apparatus having the configuration described in -1-, FIG.
2 is shown being fed into the device with the foreign matter 12 attached to it. Here, the foreign matter 12 is attached to the inclined guide 5
contact with the contact point of the controller 2 and send an electric signal to the controller 2.The controller sends a control signal to the morph to control the rotation of the morph and stop the rotation of the morph, or
As shown in the figure, the morph 1 is rotated in reverse or stopped after being reversed for a certain period of time. After removing the foreign matter in this way, the reset switch 4 is pressed to return the morph I to normal rotation.

In addition, by attaching a ferromagnetic material to the back surface of the inclined kite 5 with an electric contact member, it is possible to obtain the effect of further ensuring that foreign objects come into contact with the contact point.

In the illustrated embodiment, the contacts of the electrical contact member are arranged in a parallel and intersecting manner; however, the arrangement is not limited to this arrangement, and any opposing arrangement pattern can be adopted.

Since the present invention is configured as described above, by controlling the operation of the drive device based on the foreign object detection signal from the electric contact member arranged in the feeding guide part, foreign objects such as clips and insect pins can be left attached. ) It is possible to avoid feeding sheet-like objects into the device, which has a significant effect on preventing damage to the feeding rollers and the device.
