Abstract

PURPOSE: To confirm a full by providing a stop means on one end of a placing shelf and providing a sensor engaging between support bodies for supporting the rear edge of a record paper in the area projecting beyond the stop means and detecting the record paper slipped down by the full. CONSTITUTION: A recessed part is formed on the edge 20' of a placing shelf 10 and a scanning lever 34 (sensor) can be moved vertically through the recessed part. When the record paper 22 carried by a roller couple 14 reaches a holding flap 30, the flap 30 is pushed down against a spring and the record paper 22 is placed on the placing shelf. The duty of the flap 30 is that the record paper 22 stopped by the stopper 16 reaches the full position 22" and the slip down is prevented so that the record paper 22" more than that is stopped on a position 27. Therefore, when the scanning lever 34 is moved and contacted to the record paper 22" stayed on the position 27, the scanning lever 34 is inclined and the signal is output and the full is confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a storage device for sheet-like recording paper distributed in an office machine.

(Prior Art) Such a storage device, for example, places sheets of paper supplied by a copying machine on a shelf and separates them into sheet-like recording items according to a predetermined program.
At least one, however, generally has a large number of stacking shelves placed one above the other. For this purpose, the roll pairs are each moved to a loading shelf on which the recording sheets to be dispensed must be placed according to a predetermined tabular diagram. Generally, the loading shelves, which are open at the receiving end, are inclined upwardly in the supply direction. If the shelf is now full of recording papers, there is a risk that one or more recording papers will slip back and form a dam. Therefore, it is necessary for the program control device to detect a loaded shelf in order to take corresponding measures. Such detection can be performed, for example, by a signal that calls the worker's attention, and this situation can be improved. However, it is also possible, for example, to direct recording sheets destined for a full storage shelf to a spare storage shelf.

In principle, it would also be possible in practice to detect the number of recording sheets guided to a certain shelf by means of a program control device. However, even with this method, the number of sheets of recording paper that fills the shelf is not uniquely determined. This is because the filling rate depends on, for example, the storage of paper and the flatness of the sheet.

(Problem to be Solved by the Invention) Therefore, an object of the present invention is to provide a storage device that detects by a simple means when a certain shelf is filled with sheet-shaped recording paper. It is said that

(Means and Effects for Solving the Problems) A recording paper storage device distributed in an office machine according to the present invention is provided with at least one loading shelf for feeding recording papers by one pair of rollers. The shelf is provided with one stop means for limiting the stacking surface at one end facing the pair of rollers, and has an area projecting beyond the stop means against the feeding direction of the recording paper to detect the recording paper. and further comprising a sensor arranged to periodically scan in a direction substantially perpendicular to the stack surface after dispensing each recording sheet and connected to an evaluation circuit; The recording paper is characterized in that it has a support provided in the sensing area on a line extending transversely to the feeding direction to support the trailing edge of the recording paper, and the support engages with the sensor.

In such devices, recording paper consisting of a single sheet may be left on one end of this shelf if the trailing edge of the sheet is not properly rested on the stop surface. Detected by Senna. Generally, this indicates that the loading shelf is full.

However, the recording paper fed to the stacking shelf by the rollers may be caused by other reasons, such as the recording paper being uneven, or as a result of a feeding failure, the roll pair may not be able to provide sufficient momentum to the recording paper and reach its final position. Even if you don't arrive, you can still get assistance.

The device according to the invention therefore not only detects when a storage shelf is full, but also detects whether a storage shelf is available, for example by means of a signal to the operator or by a switch circuit inherent in the device, to carry out the appropriate function. Modify it so that it can be distributed to.

The arrangement according to claim 2 is advantageous if the loading shelf has a floor plate with an extended edge DK.

In the embodiment of claim 3, the scanning is carried out mechanically, instead of using an electrical solution, e.g. using photocells. In an arrangement according to claim 4, the scanning lever is guided through the loading shelf in order to carry out the scanning operation. This is done, for example, each time recording paper is supplied to the shelf.

According to an embodiment of the present invention, the scanning lever is actuated directly by means of an electric switch or indirectly by means of a photocell. This photocell becomes a contactless electrical switch.

In particular, when operating with a photocell, the scanning lever is not loaded, so that the recording paper is not stressed at all by the scanning lever.

The configuration of claim fA6 is particularly advantageous when a plurality of loading shelves are used, and the scanning lever can recognize that the recording paper is not placed properly, regardless of the direction of movement of the lever. This allows quick confirmation.

According to the structure of claim 7, the scanning lever is connected to the pair of rollers that supply the plurality of loading shelves via the support body to which the scanning lever is attached.

This method eliminates the need for a special motor arrangement for the scanning lever.

In an eighth aspect of the present invention, the pair of rollers are fixed and arranged to swing around one pivot shaft in order to use nine loading shelves.

With this arrangement, the recording sheets are distributed onto one shelf, and the pair of swingable rollers is normally returned to the initial position whenever necessary. As a result, the next paper distributed by the office machine can be captured at a fixed position.

Due to this rocking movement, a full shelf can be immediately detected by a sensor connected to the pair of rollers.

In the configuration of the ninth aspect, since the recording paper that has fallen through the laminated glass reaches below the holding flapper, this flapper is located near the pair of rollers and prevents the jamming of the recording paper that has fallen through the glass.

If the holding flapper has a small opening of 90", for example 20c', the flapper will prevent the recording paper from being lifted up by the rising sensor. This will prevent the sensor from moving downwards but upwards. Even when moving, you can always check that the storage shelf is full.

IQIn theory, it is not necessary to detect the exact fullness of the loading shelf, but when the first recording paper exceeding the scheduled filling capacity appears, this recording paper will slide onto the holding flapper and
Therefore, it is necessary to be detected because it is within the range of the sensor.

(Example) Embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a part of the floor plate 10 of the Fi shelf 11 and the upper roller 12 of the roller pair 14.

At one end of the shelf 11 facing the roller pair 14, an edge 20, 20' is formed which projects beyond the stop surface 16 delimiting the laminated surface 18 of the bottom plate 10.

In FIG. 1, the dashed line indicates the position of the surface 18 on which the recording sheets 22 are stacked, and the recording sheets 22 are fed in the feed direction 24 through the roller pair 14.

Here, the recording paper is a single sheet on which information is recorded by copying, printing, or other means, and may be something like a perforated card.

The stop surface 16/d edge 20, 2D'lC is located on two retaining flap units 26, each of which has a retaining flap 30 held in the high position by the force of a spring 280. have.

The holding flap 30Fi and the stopper surface 16 act to prevent the recording sheets from sliding back toward the roller pair 14 when the recording sheets are stacked to a specified stacking height.

The upper edge 27 of each retaining flap unit 26 serves to support the recording paper 22' that has been dislodged from the stop surface 16.

The edges 20, 20' of the floorboard 10 are provided with slot-shaped recesses 52.
divided by. A sensor in the form of a scanning lever 34 is movable through the recess 52 approximately at right angles to the floorboard 10. The rear arm 56 of the scanning lever 34 is designed as a shutter for the photocell 38.

When the photocell 38 is moved along with the scanning lever 54 provided on the angle member 40 through the surface of the floorboard 10, the recording paper 22# remains at the edge 20, 20' or 27 in the portion 22# and is located in the recess. 52, the scanning lever 34 is tilted.

This outputs a signal, which is led from the photocell 38 to the control circuit via the conductor 42.

In FIG. 2, each roll 12, 12' of roll pair 14 is shown. Roll pair 4 located at the front in the supply direction 24
The clamping position 46 of 4 is on one axis along which the two roller pairs 44.14 are swung, and these roller pairs 44.1
4 are provided in a fixed arrangement relationship with each other.

Roll pair 14.44 and funnel-shaped guide member 48°48'
are constructed in one assembly so that they can swing together,
The roll pair 14 can also be used for the shelf 11 for holding the remaining rolls arranged in a stacked configuration.

The mounting shelves 11 are arranged parallel to each other on shafts determined by the clamping positions 46. The loading shelves 11 all have the same recesses 32, so that when the assembly with the roller pairs 14, 44 is swung about the axis of the clamping position 46, the scanning lever 34 moves through all the recesses 32. The photocell 58 and the scanning lever 34 are firmly connected to the guide member 48, 48' via a supporting mechanical connection 50, so that the scanning lever 34 can scan all loading shelves 11. Can be done.

FIG. 2 shows that the recording paper 22' to be fed is conveyed to one of the shelves 11 in the feeding direction 24 by a pair of rollers 44, . 14 is shown. As soon as the leading edge of the recording paper 2.2' reaches the retaining flap 30, this flap is pressed down against the force of the spring 28, so that the recording paper 22'
can pass through the position unhindered.

As mentioned above, the retaining flap 30 has the function of preventing the recording paper from returning to the roller pair 14 and preventing it from being disturbed there. It is located directly above the retaining flap 30 that is held.

The opening angle of the retaining flap 30 must be less than 90°, preferably 20°.

The scanning lever 54 in FIG. 2 becomes a single shutter 36, which blocks the light beam of the photocell 38 only when it is moved upwardly.

By providing a second shutter, not shown, the scanning lever 34 can also be designed to block the light beam of the photocell 38 in either direction, thereby generating a signal in each direction.

The scanning lever 34 is held in the initial position shown in FIG. 2 by a spring, not shown.
The direction of tilt of the dispensing device, including the roll pair 14.44, is shown, as well as the direction of oscillation of the scanning unit, including the photocell 38 and the scanning lever 34.

(Effects of the Invention) The present invention has one stop means at one end of the 11c shelf facing the roller pair, and between the supports supporting the trailing edge of the recording paper in the area projecting beyond the stop means. By providing a corresponding sensor, the sensor detects the recording paper that first slipped off the full shelf, making it possible to confirm that the shelf is full of recording paper. can.
