专利摘要:
The invention relates to a device for collecting and depositing signatures which, arriving processed by rollers and transversely cut from a web, can be pulled apart by means of an acceleration device, can be offset laterally with respect to one another, in each case between the leading and trailing edge, by means of a deflection device which can be actuated in the signature cycle, can be collected in receiving compartments formed from vanes of a vane wheel driven in the collecting cycle and can be pushed out from said compartments onto a delivery conveyor, the signature cycle being an integral multiple of the collecting cycle. In order to design a device of the above type in such a way that the book blocks are precisely aligned at a high work speed, and with a particularly compact structure of the overall device, the invention is characterised in that the vanes are mounted so as to be pivotable axially parallel to the vane wheel axis on a hub of the vane wheel, in that, with uniform movement of the hub, the pivoting of the vane to be loaded can be controlled periodically in the collecting cycle with a phase of rapid movement into the initial receiving position, with a phase of slow movement in the angular collecting region, and with a phase of rapid movement out of the end receiving position, and in that the receiving compartment is formed by the vane and a leaf or wire spring connected to the rear of said vane. …<IMAGE>…

专利说明:

3. Each bucket 7 has a passage radially to the axis of rotation 8 and a protrusion 9 directed in the direction of arrival, on which each signature 3 hits. From the inner edge of this protrusion 9 there passes a deflecting surface 10 with an increasing radius, with the help of which The signature dropped by the protrusion 9 with its upper edge, before returning the protrusion to its horizontal initial position, is pressed outward from the cam, so that the next signature can easily fall down. For the reliable direction of the signatures 3, the lower guide roller 11 with the tape 4 lying on the same side of the signatures 3 as the cams 7 is arranged under the cams 7. The lower guide roller 12 of the tape 5, on the contrary, is located outside the outer end of the passing past him the blades 13 of the blade wheel 14 with the hub 15.
Each of the blades 13 consists of a row of plates arranged next to each other. Accordingly, the blade 13 of the blade wheel 14, the leaf or wire spring 16 connected to it and fixed, but according to the signature length, the adjustable guide 17 limits the receiving part 18 of the blade wheel 4. All blades 13 are installed with a possibility of swinging on the hub 15 around the axes 19 of swing, parallel to each other and the axis of rotation of the blade wheel 14. The blades 13 during each revolution of the blade wheel 14 through the cam disc control, through roller levers and the like swing around the axes 19 of the swings, and It is in such a way that, in connection with the peripheral speed of the impeller 14, which changes during the rotation of the blade wheel 14, but is generally consistent with the arrival of individual signatures 3, the blade is located a short distance from the point of collision of the projections 9 of the cams 7.
During the collision of the following signatures, the paddle wheel slowly, correspondingly to the thickening package of CHI-natures, moves further, and after resetting a certain number of signatures 3 of the lower unit 22, it rapidly moves further, while the next blade 13 quickly moves to the initial position of the previous blade

-
and the previous blade with the book block 20 located on it during deceleration of the moving / rc to the axle chain conveyor 21 in the last segment of the movement. The book block 20 is dropped to the axle conveyor 21 when passing the guide 17.
In the discarded signature 3 of the receiving part 18 of the impeller 14 under the cams 7, close to the internal restriction of this part of the guide 17, a braking device is provided in the form of a brush 22 with a bristle facing the limiting receiving part of the blade 13. This brush 22 moves approximately perpendicularly relative to this blade 13, which is indicated by the arrow 23.
Instead of braking 22 to hold and hold in place of the forming book block 20, several flat or wire springs 16 can also be provided in approximately the same direction as the blade 13. The adjustment of these flat or wire springs 16 can be carried out separately or together through the center axis of the blade. the wheels 14. The springs 16, fixed in the hub 15 of the impeller, serve to press the incoming signatures 3 against each other in part 18 and consequently slow down and then hold instead of the formed books x blocks 20 vykladyvanii them on a chain conveyor trunnion 21.
