Description
Technical field
The present invention relates to a kind of device that is used for transport of sheets, have some grippers, printed sheet is being clamped in these grippers on an edge in the course of conveying of a delivery track, and this device also has a mechanism that is used for forming a hydromechanical carrying mattress below printed sheet.
Background technology
Be well known that for sheet-fed press, some air-breathing and/or air-blast devices are set, go up ahead of the curve when printed sheet and grasped by a grippers and when a delivery track moves, these air-breathing and/or air-blast devices apply a power effect on a printed sheet.At this, form a carrying mattress, so printed sheet can not contact with guide plate, the latter is along the delivery track setting.The carrying mattress is produced by nozzle, and these nozzles are built in the guide plate.Be known that: be provided with a plurality of nozzles that are provided with the net grid in a guide plate, air blast blows out from nozzle along a preferred orientations.The quantity of nozzle, structure and physical dimension are selected like this, make printed sheet flow imperturbably as far as possible.
In printed sheet guiding device according to DE 103 23 468 A1, on a guide plate, be provided with the air-blast nozzle of some slot shapes, the slot width here can be regulated by means of a transmission device.The front of nozzle is provided with a fluid passage respectively, is provided with a kind of gas permeable material as throttling arrangement in described fluid passage, so that make the air homogenising of outflow, and reinforcement is to the support force of printed sheet.
Described a kind of device that is used for floated guiding printed sheet in DE 100 64 589 A1, wherein provide a mattress by nozzle, this mattress is worked according to pneumatic paradox principle.Obtained stable and jitter-free guiding by means of nozzle, these nozzles are similar to diffuser and have the guide surface of dispersing like that.Preferential is: each nozzle begins to be the sidewall that trumpet-shaped enlarged is configured with side direction together with guide surface at the blast orifice place.
A kind of device that is used for contactlessly guiding printed sheet has been shown in DE 197 21 907 A1, and wherein a printed sheet guide plate is provided with the nozzle that some nozzles have the air guide face of inclination.For fear of set-off takes place, between the plane of the flow direction of the air that air-blast nozzle flows out and printed sheet spigot surface, be an acute angle.
According to DE 101 41 415 A1 be used in the device of sheet-fed press guiding printed sheet, equipped some guiding sheets elements, the latter has free injection nozzle and throttle nozzle.These nozzles are irrespectively loaded with different stress levels each other.Be provided with the minor air cell that constitutes by perforated plate in the front of air outlet slit.Produce throttling action thus, wherein, reduced the speed of the air blast that flows out perpendicular to the printed sheet direction.
A kind of printed sheet guide plate with slot shape opening has been described in DE 199 05 095 A1.Be provided with a fluid conductors in each opening, the latter can regulate with respect to the angle on guide plate surface.Like this, the carrying effect of the air blast that is flowed out by opening can adapt with weight per unit area, subject matter (Sujet) and the speed of printed sheet.
According to the carrying that is used for printed sheet of DE 103 04 618 A1-or guiding device have the outlet that some are used for air blast, wherein, these outlets are connected with the air blast source by a throttling highway section.The outflow direction of air blast is perpendicular to the surface of printed sheet.
DE 197 21 390 A1 show a kind of device that is used at a printing machine transport of sheets, and it is right wherein to be provided with a plurality of nozzles on a spigot surface.A nozzle of a nozzle centering blows to printed sheet with air blast with an acute angle.Second nozzle of a nozzle centering then makes the surface of air blast perpendicular to printed sheet.By second nozzle, near negative pressure region that the diffusion by air-blast nozzle causes tight, additionally air is blown to below the printed sheet, so printed sheet is pressed off from the set-off position that is caused by negative pressure in other cases by impulsive force.
In order contactlessly to guide printed sheet,, be provided with first and second nozzle configuration according to DE 196 28 620 A1.The nozzle of first nozzle configuration makes the throughput direction orientation of air blast towards printed sheet, and the nozzle of second configuration produces swirling air stream, and the latter applies a carrying effect outwardly perpendicular to printed sheet.
The shortcoming of solution of the prior art is, and is excessive with respect to the air-flow on the printed sheet throughput direction perpendicular to the air-flow on printed sheet surface, wild effect therefore occurs.
