Definitions
- the innovation concerns a feed table for creating sheets to a sheet-processing machine, in particular a printing machine, the sheet from a sheet feeder into a roughly horizontal feed level can be fed and the opposite of the Feed plane is inclined, being approximately over the range of A deflection roller between the feed level and the feed table is arranged through the sheet from the feed level in the level of the feed table can be deflected.
- the innovation concerns a feed table for creating sheets to a sheet-processing machine, in particular a printing machine, the sheet from a sheet feeder into a roughly horizontal feed level can be fed and the opposite of the Feed plane is inclined, being approximately over the range of A deflection roller between the feed level and the feed table is arranged through the sheet from the feed level in the level of the feed table can be deflected.
- the task of the innovation is therefore to create a feed table to create the type mentioned above, without the application of force for processing a wide variety of sheets, in particular is also suitable for arches with high rigidity and all bends are safely deflected as well as to the feed table supplies exact further transport, in particular in the Center of the sheet in the area of the surface to be printed none Damage may occur.
- this task is solved in pairs pulleys assigned to the edge of the belt table are provided.
- the pulleys are vertical spaced from the plane of the feed table, such that they then come into effect when substrates of a certain thickness are to be promoted.
- the pulleys are with a side scanner connected manually or automatically on the side edge of a to be separated Sheet stack are adjustable.
- the pulleys spring-loaded and in its basic setting compared to the Conveyor roller adjustable.
- the pulley is freely rotatable and arranged so that it covers the surface of the substrate burdened as little as possible.
- the pulley is with the side edge scanner connected for the feeder stack in such a way that with an automatic format setting the Deflection roller also automatically on the side edge of the sheet is set.
- a Device of this type has an advantage especially when if sensitive substrates are to be conveyed, on the one hand have a large thickness and on the other hand thereby have to experience a high resistance when turning. The The conveying power must then be high and there is a risk of damage the surface is increasing. By side Arrangements of the deflecting rollers are surely avoided.
- a conveyor roller 1 is shown on which a transporting sheet 2 rests.
- the conveyor roller 1 opposite A conveyor roller 3 is arranged.
- This conveyor roller 3 presses the sheet 2 against the conveyor roller 1, so that this can move the bow 2 forward.
- Sheet 2 is in here horizontal direction as seen from the surface of a stack of feeders arrives.
- the sheet 2 to be transported must therefore from the horizontal by means of the driving force of the conveyor roller 1 in an inclined downward transport direction be performed.
- deflection rollers are no longer shown here provided in pairs in the area of the center of the arch or can be arranged in groups. You can do this Devices used as described in the prior art that consist of a plurality of idlers that for example, are arranged in an arc and one behind the other work without pressure on the bow.
- the conveyor roller 3 shown in Figure 1 is suspended on a pivotable lever 4.
- the pivotable lever 4 in turn can be moved on a holder 5 in the direction of the axis of rotation of the conveyor roller 3.
- the bracket 5 is slidably suspended on guide rods 6. It can be set on the guide rods 6 in the axial direction.
- a spacer 7 is provided between the bracket 5 and the lever 4. This spacer 7 has a compression spring 8, the effect of which is adjustable.
- the response point of the conveyor roller 3 is also adjustable, in which a nut 9, which forms the support for the compression spring 8, is arranged at a distance from the lever 4.
- the compression spring 8 will only respond when the lever together with the conveyor roller 3 has been raised up to the nut 9. This is only the case with a certain thickness of substrate.
- the conveyor roller 3 In the area of the sheet transport on the conveyor roller 1, the sheets 2 are at least twice one above the other due to the shingled conveyance, therefore the conveyor roller 3 is lifted away from the conveyor roller 1 accordingly. In the case of thinner substrates, the conveyor roller 3 moves on the lever 4 only as a result of its own weight over the sheets to be conveyed. A load by the compression spring 8 is not yet given. The influence on the sheets 2 to be transported is still slight. Likewise, dangerous damage to the sheet corners due to the low contact force cannot occur for thin substrates. Only from a certain printing material thickness, which can be set by means of the aforementioned nut 9, is a compression force generated by the compression spring 8 on the sheets 2 to be conveyed. The compressive force can be influenced in a wide range and also very sensitively by selecting an appropriate compression spring 8 and adjusting the nut 9 accordingly.
- the arrangement is in the direction of the conveyor roller 3 shown.
- the conveyor roller 3 is in the area of the side Edge of the conveyor roller 1.
- the conveyor roller 3 is how Shown here in more detail by means of the lever 4 on the holder 5 and performed on the support rods 6.
- the supporting role 3 is by means of the elements mentioned in the axial direction Conveyor roller 1 suspended transversely. You can so on Edge of a sheet 2 to be guided over the conveyor roller 1 can be set.
- the device can be further developed within the framework of the concept, that not only a conveyor roller 3 but possibly two or more conveyor rollers 3 arranged one behind the other can be, the second conveyor roller an improved Redirection of the sheet 2 into the incline of the feed table 16 can effect while the first conveyor roller 3 mainly Supplies propulsive forces.
- the burden of sensitive Sheet material is thus placed in the edge area and from the area to be printed out.
- the setting of the provision of the conveyor rollers can be stopped 3 be automated.
- Activation of the Conveyor rollers 3 take place automatically by the employment for example pneumatically.
- the format-related assignment is through the connection to the side edge scanning already involved.
- the assignment to the sheet thickness results about the setting of the compression spring 8 in relation to the position the conveyor roller 3.

Abstract
Description
- Fig. 1
- eine Seitenansicht einer Förderrolle,
- Fig. 2
- eine Längsansicht einer Förderrolle bezüglich. der Bogenseitenkante und
- Fig. 3
- eine Draufsicht auf die Anordnung der Förderwalze mit Förder- und Umlenkrollen.
Erst ab einer bestimmten Bedruckstoffdicke die mittels der genannten Mutter 9 einstellbar ist, wird eine Druckkraft durch die Druckfeder 8 auf die zu fördernden Bogen 2 erzeugt. Die Druckkraft kann in einem weiten Bereich und auch sehr feinfühlig mittels der Auswahl einer entsprechenden Druckfeder 8 und einer entsprechenden Einstellung der Mutter 9 beeinflusst werden.
