Device for distributing treated, ejected at an ejection opening Scroll

The invention relates to a device for distributing and layering treated, at an ejection opening ejected leaves, and in particular a device

409807/0369

device, in which the rotary movement of a shaft is used to treated, or. processed sheets ejected at an ejection opening to deflect at the side edges with respect to the sheet ejection direction.

As is known, sheets treated or processed in a corresponding device are ejected to the outside from the device via an ejection opening in order to one after the other in a receptacle, which is attached to the Discharge opening is appropriate to be piled up in a pile. Such sheets can be attached to magnetic sheets on which a magnetic record is transferred in a magnetic transfer device sheets copied by a copier, sheets printed by a printer, and others.

However, the treated or processed sheets that are ejected at the ejection opening, are stacked in the receptacle only in a stack, but they can made either as a function of to the sheets sorted different treatment in veBSchiedene stack piled still stacking each having a predetermined number of sheets, for example, lf10 sheets.

Although sorters or folders are known, by means of

409807/0369

If the sheets are to be automatically sorted into different stacks, such devices have to be set up for feeling the applied treatment method or for feeling the treated leaves as well as an initiation for Change the direction in which ■ the sheets are ejected are provided, or for the alternate movement and displacement of the sheet receiving container. This will but the entire structure of the device is complex and a complicated sensing and sorting mechanism is required, making the device very expensive overall. Especially if the receptacle can be moved, the weight of the stack of sheets adds to the total weight of the container so that its movement and displacement are not carried out with a simple mechanism can be; the entire device must therefore be designed as a massive and heavy unit.

On the other hand, however, it is imperative that the treated or processed sheets from the respective treatment device provided for this purpose be ejected to the outside; for further treatment of the ejected leaves, however, no additional costs as well as additional requirements in structurally or spatially.

The invention therefore creates a device for

409807/0369

sharing of ejected sheets with which a certain, Counted number of sheets can be sorted out by changing the direction of rotation of a rotating shaft to deflect the ejected sheets at the edges the shaft is used. Furthermore, a device for distributing ejected sheets is to be created which compensates for the delay that results for the rear part of the sheet when it comes to the Wave comes into contact and is thereby deflected.

The invention thus provides a device which treated or processed, ejected at an ejection opening Leaves at the side edges deflects with respect to the ejection direction, for this purpose a distributor shaft is used in the sheet ejection path in the direction of the sheet ejection and arranged in their direction of rotation is reversible. The Einridtung also has a rapidly rotating feed part, which has a lag of the rear part of a deflected into the deflection Sheet balances.

The invention is explained in more detail below with the aid of a preferred exemplary embodiment, for which purpose the attached Drawings are referred to «They show:

Fig.l from the front a perspective view of the

4 0980 7/036 9

direction for distributing ejected sheets according to en he embodiment of the invention;

Fig. 2 is a side view, partly in section, of the main parts of the device shown in Fig. 1; and

3 shows a perspective view of a damping device »

In Fig.l is a treated or processed sheet 1 shown, which of a corresponding treatment or. Processing device in which an arrow a specified direction and fed from this device via an ejection opening, which a pair is in the having rotating ejection rollers 2a and 2b in the directions indicated by arrows b and c are ejected outward will. The sheet ejected from the ejection port shown by one-dot chain line is as shown in FIG Fig.l is shown to be transported in the direction of the viewer. The path along which the sheet will travel is referred to below as the ejection path.

A distributor shaft 3 is arranged in the ejection path and aligned in the ejection direction of the sheet IA. At

40980.7 / 0369

its opposite ends is journalled in bearings 3 Verteüerwelle 4a and 4b, which are in the front and rear walls ^5a and 5b attached to a receiving container or a tray. 5 The front and rear walls 5a and 5b are connected to one another via the front and rear edges of floor panels 5c, 5d, which are formed in the shape of an upwardly directed angle, and are fixedly attached to the edges of the floor panels. At their lower edges, the angled floor panels 5d and 5d are bent upward in a direction perpendicular to the respective plane of the floor panels 5c and 5d, as a result of which left and right side walls 5e and 5f are formed. The receptacle or the Kblage 5 has a box shape together with the bottom plates aligned upwards in the form of an angle. The distributor shaft 3 is arranged above and parallel to the edge of the angle formed by the base plates 5c and 5d.

As shown in Fig.2, is the container or shelf 5 arranged obliquely downward as seen from the ejection opening. The rear wall 5b has an upper band 5g which is bent backwards towards the ejection opening formed by the rollers 2a and 2b is. This is at the rear end 5h of the band 5g bent down a little. On the upper band 5g are

409807/0369

laterally wedge-shaped lugs 5i and 5 j provided which protrude from the tape obliquely downwards in the form of lobes. The lateral wedge-shaped lugs 5i and 5 j as well the rear end 5h of the band 5g are therefore bent at an angle so that the leading edge and the adjoining marginal areas of the sheet IA do not differ from the upper one Belt 5g are adversely affected when the sheet ejected through the ejection opening is in contact with the belt comes and vat this is directed while it is conveyed on in the ejection direction.

One end of the distributor shaft 3, which by means of the bearing 4b is held in the rear wall 5b, extends rearward through the wall, and on its As shown in FIG. 2, a belt pulley 6 is attached to the end of 3a.

On the underside of the rear wall 5b is an electric motor M attached, which the Ai. drive targets for the distributor shaft 3 is shown. The motor M is housed in the wedge formed by the floor panels 5c and 5d and its output shaft Ma extends outward through the rear wall 5b. There is one on the output shaft Ma Belt pulley 7 attached; a belt 8 runs around the two pulleys 7 and 6. When the motor M is then operated is, the distributor shaft 5 by means of the Rie-

40980 7/0369

mens 8 rotated. The direction of rotation of the motor M is reversible and can be switched by a switch (not shown) controlled accordingly.

Ajn the end of the distributor shaft 3 is also fast fixed rotating feed part 9, which has an annular body made of a material with a high coefficient of friction, such as rubber or something similar, and which on the peripheral surface of a disk-shaped part 10 is attached to the shaft 3 is held. The rapidly rotating part 9 has a diameter that is larger than the diameter of the shaft 3 · When the rear end of the raised hen Sheet IA comes into contact with the periphery of the rapidly rotating feed part 9, this part moves the rear end of the sheet quickly in the direction of rotation of the distributor shaft 3t whereby the ejected sheet IA, which due to the contact of its front end with the distributor shaft 3 has been inclined with respect to this shaft was aligned in a position parallel to the shaft.

On the top of the front wall 5a of the container or the Tray 5, a pair of guide parts 11 and 12 are attached. The two guide parts 11 and 12 are above the distributor shaft 3 arranged and their free ends 11a, 12a, which are bent upwards, extend in the direction of

409807/0 3 69

the ejection opening.

A Däapf guide device 13 is attached to the top of the front wall 5a opposite the rear wall 5b. As shown in Fig. 3, the damping device 13 has an abutment plate Ik which is attached to the front wall 5a together with an interposed part 15 made of foam rubber; the damping device prevents further movement in the ejection direction of the sheet IA which has been thrown out if its leading edge strikes this damping device. The foam rubber part 15 can also be replaced by a spring.

When the motor M is running during operation and its output shaft Ma is rotated in the ear pointer direction of rotation, as shown in Fig.l, the distributor shaft 3 is also via the Riemenschd. be 8 clockwise, ie driven in the direction of rotation indicated by an arrow d. When an ejected sheet IA is then displaced from the ejection opening along the ejection path, the sheet IA is guided by the guide parts 11 and 12 to the container or the support 5. When it reaches the center of the container, its front end bends downward due to its own weight, as shown in Fig. 2, and thereby comes into contact with the distributor shaft 3.

409807/0369

As soon as a contact is made, the front end becomes of the sheet IA deflected to the right by the circumferential surface of the clockwise rotating shaft 1, as shown in Fig.1. Such a deflection occurs while the sheet is advanced in the eject direction.

If the front end is deflected to the right, hey the ejected sheet IA an inclined position with respect to the distributor shaft 3, as shown in FIG. if then the sheet IA is completely ejected from the ejection opening, its rear end runs over the upper one Belt 5gi falls down due to its own weight and comes into contact with the rapidly rotating one Feed part 9 · As soon as such a contact occurs, the sheet takes the position IB shown in FIG one, and its front end is immediately grasped and quickly to the right by the feed part 9t which rotates together with the distributor shaft 3 i ™ diverted. This deflection automatically eliminates the lag of the trailing end which has lagged in the direction of deflection with respect to the leading edge of the sheet; this then causes the thrown sheet IA, which was previously arranged obliquely with respect to the distribution erwellβ 3, aligned in a position in which it is parallel to the distributor shaft 3.

409807/0369

The ejected sheet IA # is then taken from the distributor shaft 3 and the rapidly rotating feed part 9, while maintaining the assumed position, and then falls onto the bottom plate 5c where it is piled up will. The process described above is repeated every time when a sheet is ejected; this causes the sheets to be stacked on the bottom plate 5c stacked on top of each other. When the engine is turned on like this is that it rotates counterclockwise, also rotate the distributor shaft 3 and that fast rotating feed part 9 counterclockwise and thus in the direction indicated by an arrow e Direction. With a counter-clockwise rotation if the thrown leaves are deflected to the left, as shown in FIG is similar except that the direction of deflection is opposite. The deflected sheets are then one after the other stacked on the base plate 5d in a stack.

In this way, the ejected sheets 4A can be sorted be, the direction of rotation of the distributor shaft 5 switched or vice versa only according to the invention needs to be.

The direction of rotation of the motor M can be switched manually

will. On the other hand, an automatic switchover can also be made by changing the number of over the ejection opening ejected sheets 1 with a corresponding Device is counted and a look signal is generated when a certain number of sheets has been counted. An implementation example of this is provided described with reference to Fig.l. A lamp L is arranged near the feed path of the sheets 1 and is on the Sheets too aligned; a calibration element P is mounted exactly opposite the lamp L on the opposite side of the feed path. The outcome of the Light receiving element P is connected to a counter K, which counts the output signals, which each time the light is passed from the lamp to the light-receiving element through a Sheet is interrupted. The counter K then emits a switching signal when a certain number has been counted by leaves; when the switching signal is applied, the direction of rotation of the motor M changed. In this way, a predetermined number of sheets can be sorted automatically.

While in the embodiment described above, the ejected sheets IA either to the right or to deflected to the left and thus sorted out, a number of such devices can also be placed on one in
