Abstract

The invention relates to a device for transporting sheet-like substrates with a circumferential suction belt and a suction box below. The device is characterized in that, at least in a part of the suction box, additional and switchable suction openings are present, by means of which the suction belt itself can be sucked.

Description

Suction belt by revolution is used for the equipment of conveying
Technical field
The present invention is applied in page printer by the suction belt of revolution.
Background technology
When the moment that page is delivered to suction belt from feeder, there is the negative pressure of unexpected onset.This negative pressure is by suction belt Being pressed onto on suction box, this causes the friction between above-mentioned two parts (suction belt and suction box) to increase.That therefore triggers drives Kinetic moment change produces impact with the form of the fluctuation of transporting velocity.And when page is delivered to collector output from suction belt Another moment, the pressure owing to reducing suddenly can form this velocity perturbation of suction belt.Which results in and be placed exactly in print head Forms of collision (the sto β artig) motion of the page of lower section, and, may in the digital printer based on conveyer belt Visible striped is caused to be positioned on printing figure.
DE 3017420 A1 describes one and is carried out belt tension stable by casing by means of two compensation masses System.Here, two paper tape axles are relative to driving roller to be fixed on the bearing part supported movingly.Said two paper tape axle Keep contacting with driving roller by means of pressure apparatus.For the mass mement of inertia making movable bearing part and the bobbin attached troops to a unit Compensate mutually, compensate mass and be so movably coupled with bearing part so that mass inertia is cancelled out each other.
DE 10216340 A1 contain a kind of for by mass point-blank or class guide point-blank collision balance set Standby.Here, the lever that can be rotated to support between equipment end on an end of this equipment with point-blank or class straight line The mass of ground movement is connected, and makes another end be connected with balance mass block by lever, thus equilibrant is The inertia force of mass.
Summary of the invention
The task of the present invention is, proposes a kind of equipment compared with prior art made moderate progress, and this equipment has in application For carrying the printable fabric of page form in the case of the suction belt of revolution, the suction belt of this revolution is by suction belt undesirably Velocity variations offset.
Described task is addressed by having the equipment of feature described in claim 1.
The method according to the invention is applied by the suction belt turned round in page printer.
The present invention sets: the suction box being connected with suction belt has additional, switchable suction opening.These are taken out Inhale the opening suction for suction belt self.Therefore, suction belt does not the most have opening.By described suction belt Suitable suction creates counteracting friction, and, accept when the printable fabric (hereinafter referred to as page) of page form is sucked band Or during output, the friction between suction belt and suction box also then is able to keep constant.In other words, it is placed or quilt when page When again taking off (friction between suction belt and suction box also then is able to keep constant).Therefore the change of driving moment is prevented Change.Further advantages is that and introduce heat consistently.
Embodiment of the present invention set: each first pump orifice and each second pump orifice are matingly constituted, Further, it is connected with each other by movable switching device.
The improvement project of the present invention sets: switching device is taken out first by replacing the negative pressure of increase and decrease in suction opening Inhale and move back and forth between opening and the second suction opening.
Particularly advantageous embodiment of the invention sets: additional switchable suction opening is only arranged at suction In the upstream suction areas of case and downstream output area, because only that the friction change of local, institute here may be formed State friction change must be cancelled.
Another improvement project sets: the negative pressure in being sucked the suction opening that band covers has value U1, and by page The negative pressure opened in the suction opening covered has value U2.These values U1 and U2 are the most selected so that between suction belt and suction box Or the value of the friction produced respectively between page and suction box is the highest.Therefore, perseverance is frictionally held when page carries Fixed.
Additionally, meaning of the present invention is, the interface of each suction opening of suction box is separated, thus prevents negative pressure Crosstalk.
Last improvement project of the present invention sets: the separation of the interface of suction box is realized by restriction.
As long as the present invention and the present invention are advantageously improved scheme and also are able to be mutually combined and have technical meaning Words become the present invention and are advantageously improved scheme.
About the favourable configuration scheme of the further advantage of the present invention and structure and function aspects by dependent claims with And embodiment referring to the drawings draws.
Accompanying drawing explanation
The present invention also should further illustrate by means of accompanying drawing.Mutually corresponding element with component in the accompanying drawings with identical ginseng Examine labelling to represent.The pro rata view of use is eliminated in order to preferably make accompanying drawing short and sweet.
Accompanying drawing diagrammatically illustrates:
Fig. 1 shows the suction belt of conveying page and is positioned at below suction belt the suction box with changeable suction opening Local map.Here, a suction opening is covered by page, another suction opening is sucked band and covers.
Fig. 2 shows the Local map of page printer, and this page printer has suction belt for carrying multiple page, Apply the equipment according to the present invention in the suction areas of suction belt and output area simultaneously.
Detailed description of the invention
In page 7 is received in feeder 11 and be supplied to suction belt 3.In this place, the suction through suction belt is opened The suction openings 5 that mouth 4 makes page 7 be sucked case aspirate, and the suction belt 3 that page 7 is turned round is accepted.Here, the first suction First opening 5 is covered by page 7.In this case, negative pressure U2 is applied in page 7.Open with 3 suctions covered being sucked Below mouth 5, negative pressure is to be worth U1 effect.Suction opening 5 (suction opening 5 of this suction box is not covered by page 7) when suction box It is sucked the suction opening 4 of band when crossing, is then formed without negative pressure.
Below the suction opening 5 covered by page 7, it is built with negative pressure U2.This negative pressure makes to be mounted with spring (angefedert) switching device 6 strain (anziehen) and thereby turned off the page 7 being sucked region in negative pressure U1。
Additionally, the switching device 6 on the side not covered by page 7 can act between suction belt 3 and suction box 2 Negative pressure U1, because owing to suction opening 5 is uncovered and be formed without following negative pressure: this negative pressure makes switching device 6 move for closing Lock U1.
Therefore, on each position, or played the function offsetting friction by U1, or by U2 due to page 7 It is sucked and plays the function of friction.
