Definitions
- the invention relates to a sheet feeder on printing machines, in particular offset printing presses, with a stacking table located between feeder side elements, vertically displaceable by means of a main stacking lifting device for receiving a sheet stack and with an auxiliary stack lifting device for uninterrupted sheet feeding when inserting a new sheet stack / wherein the auxiliary stack lifting device has non-stop rails for assigning non-stop rods or the like carrying a sheet of residual stack.
- Sheet feeders on printing presses are used to separate sheets from a stack of sheets and to feed them to the printing unit of the printing press. Since the height of the sheet stack decreases with continuous sheet removal, this is located on a vertically movable stacking table, so that the stacking table can be moved upwards accordingly with decreasing stack height, so that the uppermost sheets remain in the working area of a suction head arrangement, which the sheets are in the sheet stack remove and feed the sheet to the printing press.
- a so-called auxiliary stack lifting device is provided which receives the remaining sheet stack l remaining from a sheet stack during the feeding of a new sheet stack. The new sheet stack is inserted below the remaining sheet stack Is and then the remaining sheet stack 1 and the new sheet stack are brought together.
- Sheet feeders on printing machines are known in which the stacking table receiving the main stack hangs on support chains which are driven by chain wheels.
- the suspension chains are suspended via um steering chain wheels r, which on a
- REPLACEMENT LEAF arranged above the stack of sheets traverse. This traverse leads to a very high design and limits the view of the paper flow.
- Vert i ka L guides have to be relatively long and therefore up to a corresponding height, since even when the Stape Iti sch-Hubsch L tten are moved far up, an area of the guide for receiving the lift slides Lifting sled must be available for Hi Lfsstape Lhubei direction. Furthermore, it is necessary to bend the non-stop rails attached to the lifting slides of the auxiliary stack lifting device downwards so that the non-stop rods to be placed on them receive the correct working height for the remaining sheet stack L.
- the relatively high towering guides lead to the disadvantages that also exist for the sheet feeders with crossbeams, that is, the accessibility and the view are hindered; An operator's view of the paper stream on a control panel installed on the side of the operator's side wall is disturbed.
- the high design also leads to safety problems in accident prevention.
- the invention is therefore based on the object of providing a sheet feeder in a compact design which has relatively small height dimensions, has a simple construction and in particular provides free access and insertion options for an operator.
- This low overall height of the sheet feeder also leads to a consistent machine design, that is to say that feeders and printing units can be matched to the corresponding overall heights of the printing press without the feeder disrupting the machine design due to its construction-related large overall height which is present in the prior art.
- Main stack lifting device is arranged separate auxiliary stack lifting device and that the non-stop rails, if appropriate together with the lifting elements, form a frame which comprises the feeder side elements - or at least sections of them - on the outside.
- the components of the stack stacking device are thus arranged on the outer sides of the feeder rare elements, as a result of which there is complete decoupling from the main stacking device.
- the feeder side elements are preferably as
- the main stack lifting device can, for example, have vertical guides which are arranged on the inner sides of the two feeder side walls.
- guide elements of the vertically movable lifting elements of the auxiliary stack lifting device are provided on the outer sides of the two feeder side walls, so that no mutual hindrance of the main stack lifting device and auxiliary stack lifting device can occur and overlaps of components of the main stack lifting device with components of the auxiliary stack lifting device are possible, which makes possible only a very low overall height of the sheet feeder can be realized. As a result, an unrestricted free
- the lifting elements carry a frame or part of this frame which comprises the feed side walls - or at least sections of them - on the outside.
- the front and back of this frame represent the non-stop scissors that support the non-stop poles. If the frame does not encompass the entire feeder side walls on the outside, but rather passes through corresponding slots in the feeder side walls, only sections of the An Legerseiwanden are included in the frame.
- the invention also enables a common machine design, in particular the realization of a feeder shape, which is as contoured and smooth as that of the printing units.
- the lifting elements can be mounted in guides which are fastened to the outer sides of the feeder side elements. These are preferably roller guides, the rollers being supported on the lifting elements and running in guide rails fastened to the outer sides of the feeder side elements.
- the lifting elements are fastened to support chains which are driven by means of chain wheels arranged on the outer sides of the feeder side elements.
- At least one of the sprockets of each feeder side element forms a drive sprocket and the other sprockets are designed as deflection sprockets for the associated support chain.
- the two drive sprockets of the two feeder side elements are preferably arranged in a rotationally fixed manner on a common drive shaft. This is in drive connection with a drive, in particular an electric motor.
- the invention provides that on the side of the sheet feeder facing the printing press, the associated section (front non-stop rail) of the frame penetrates openings in the feeder side walls. This ensures that the front non-stop rail comes to lie in front of the corresponding side of the sheet stack, that is to say between the sheet stack and the printing unit of the printing press.
- the assigned section (rear non-stop rails) of the frame is designed to be removable. This gives unrestricted access when the rear non-stop rail is removed.
- the rear non-stop ski is preferably U-shaped, with its two legs extending approximately parallel to the outer sides of the feeder side walls.
- the web located between the two legs of the U-shaped rear non-stop ski extends over the end faces of the feeder side walls. Therefore, no breakthroughs are required in the feeder side walls.
- covers which have front slots for the exit of the legs of the rear non-stop rails.
- These covers are available for reasons of prevention; they cover the chain drives of the auxiliary stack lifting device.
- the slots in the covers, which are penetrated by the legs of the rear non-stop ski, are very narrow and narrowly tolerated, so that there is no risk of injury to an operator.
- connection point of the removable rear non-stop rails is preferably to the rest of the frame
- the guides of the lifting elements run up to the upper edge of the feeder side walls. They preferably even end in front of the upper edge, so that the feed side walls complete the sheet feeder without protruding parts or the like.
- the front non-stop rail is floatingly attached to the remaining part of the frame.
- the removable rear non-stop rail also allows a certain inclination.
- the connection point to the side frame elements allows the necessary movement.
- the legs of the rear non-stop rails are preferably designed as hollow profiles which can be plugged onto the mandrels of the lifting elements. This makes it easy to remove and insert the rear non-stop rails.
