re: device for forwarding items of mail, forms or similar. ■

The utility model relates to a gate direction to continue of mail pieces, forms or the like, which the pieces, forms or the like in puffs, fed to remove them one by one from the pile and carry them on.

When feeding mail, forms, transfers, Banknotes, etc. to sorting machines, stamping machines, counting machines, etc., it is difficult to be treated from the pile of pieces only ever to be handed over to the machine in question once at a time. In the existing systems it happens that two or glue more pieces together and put the machine in question are offered, line known per se The device is shown in Fig.l. A, B, O and D represent transport rollers that are driven in the specified direction. As a result, the conveyor belts move

in the specified direction. Pieces that are introduced at a are then discharged one at a time at c. Z represents represents a push of pieces, which is pressed against the roller A with a force K. When roller A rotates, it pushes on its rotating band S from the joint Z and takes ". at a with between the bands S and T, where they are then continued. It now happens that two or more pieces be deported and continued at the same time.

Next is a device like that indicated in Fig.2 known. In this device a roller E has been added which, in opposition to the movement of the belts S and T, but is driven at a lower peripheral speed. If two or more pieces come between the conveyor belt at the same time S and the roll E, only the piece that lies against the conveyor belt S is allowed through, while the others being held back. _

It has now been found to be a disadvantage of this system that on the two sides of the piece that has passed through it is opposite directed forces are exerted; ''. It is through it possible that the pieces passed through are damaged. When using this system for conveying letters will be Airmail letters destroyed. In addition, there must be friction between The tape and piece must be larger than that between piece and roll E. Furthermore, the insertion of a piece at b is not simply because conveyor belt S and roller E rotate in opposite directions here.

The device according to the utility model now has a role provided, which is slippingly coupled to the shoot of a band against which the pieces of Eost, forms or the like are pressed and that is resiliently pressed against said roller. The tape grips the first piece of the pile and continues it between tape and reel. When the roll and tape are in direct contact with each other, the direction of movement becomes the circumference of the roll by the direction of movement

of the tape determines the type of place and is therefore the same. If,
If there is more than one piece between the roll and the tape, the
Direction of movement of the roller is determined by the drive direction
and is then opposite to the direction of movement of the belt. The excess is now in one of the direction of movement of the
In the opposite direction and only then
When the "foremost piece, the additional roll, is over,; the piece that was held back is continued. The pieces now always happen one after the other, regardless of what they are
Dimensions. The pieces also connect directly to each other,
which cannot always be said of the existing facilities
k _a nn. This means a significant improvement in the degree of utilization.

In Fig. 3 and 4 'is an embodiment for the Yorrichtung
shown according to the utility model. In these figures is

with F denotes a role that slips with the drive ^;

Device is coupled. As you can see- ^:

borrowed, is in Fig. 3 no piece between tape S and ■

Roll F. The direction of movement of the circumference of the roll F becomes ' ■

now determined by the direction of movement of the belt and both \ move in the same direction indicated in Fig.3. That . - |

There is no difficulty in inserting pieces. j

Fig. 4 illustrates the case where two pieces are between \

Tape S and roll F are located. The direction of crushing of the roll F> will ! now determined by the drive device / the belt and the

The direction of movement of the circumference of the roller F is now the movement

direction of the band S opposite. _;

On the second piece, the first also creates a force! exercised, causing it to move to the right. The one from the role
but the force exerted on the second piece is greater than that
exercised from the first piece to the second. The first piece
moves to the right, the second to the left. The second
Piece then waits until the first of the roll F is over,
after which it is guided by the belt S to the right.

If there is only a piece between belt S and roller] ?, i.e. if roller F is no longer directly coupled to the belt, two forces act on roller i ¹ . One is exercised on the passing piece. As a result, the circumferential direction of the roll is the same as the direction of movement of the tape at the point. The other force is exerted by the belt drive mechanism; this exerts a force in the circumferential direction of the roller, opposite to the direction of movement of the tape at the point.

The coupling of Fig. 1 with the drive device of the belt is now a slipping clutch5, which is the last force with regard to the first minimal, so that no damage to the pieces occurs.

In this way the device makes the pieces pass one by one regardless of the dimensions. Difficulties are encountered with existing facilities, though Pieces of unequal dimensions are to be continued.

Furthermore, the pieces are completely connected to one another; here, too, there is a lack of something in the existing facilities.

Finally, the structure of a slip clutch is in Pig. 5 specified.

These slipping clutches are known.
