专利说明:

The invention relates to devices for laying sheets at sheet-feeding devices of processing machines, especially printing machines. In sheet-cutting machines, such as printing, sheets after printing in a sheet-cutting device are fed by gripping the storage platform, with the increasing productivity of the machine. and in the case of large formats, the building-up of the building stocks is adversely affected by the airbag formed between the building-berth and the sheet. A device for accelerating yklada slipway receiver sheet on DD-PS 111 870, With this device the sheet after opening the gripping openings normally forced air is supplied to the sheet plane. The injection air flow is controlled in such a way that the sheet is fed from the inside to the outside and the airbag is leveled. The device’s icing point is that the end of the sheet is only briefly affected by the forced air, resulting in a drop in the sheet correspondingly slower. Slow falling of the rear sections of the sheet from the sheet piping at high speeds may be the cause of the posterior edge of the pad grabbing to the subsequent sheet, on the right grip over the receiving slipway, 1 These phenomena of 1 grabbing lead to known rolls in the slipway and most - to the inaccurate formation of stocks. It is also known that, in addition to the injected air, suction devices (I1G-P52645480) are located on the top edge of the side edge. The suction attachment enhances the smoothing effect achieved by the pumping device in the sheet feeder, and the suction device is controlled in the same way as the pumping device, located above the sheet plate, the bottom edge of this device sheet in the case of large formats is subject to insufficient expansion so that the rear edge of the sheet is not completely excluded with the next sheetlet. The purpose of the invention is to create a device for laying sheets at sheet-growing devices, in which the sheet can be quickly and without rolling the rear edge accurately laid on the slipway. The object of the invention is to create a device for laying sheets at sheet-cutting devices, by means of which mashin and large formats the process of falling the sheet in the lateral parts of the rear edge of the sheet is accelerated by quickly removing the airbag between the sheet and the receiver slipway, in accordance with Bretenoux problem is solved in such a way that the slipway receiving elements are arranged at the suction side trailing edge. The suction elements are located under the suction roller and between the rings of the suction rollers on the traverse with the possibility of deflection and displacement. According to another form of execution, it is possible to place the suction elements under the rings of the suction rollers, Suction; the moving elements of the controls are coherently. The suction inlet is equipped with a grid. The advantage of the proposed device is that the lateral portions of the rear edge, which as a result of overlapping with the subsequent sheet, are only insignificantly affected by the longitudinal pressure pipes, after jumping off the rings of the suction rollers, move the sheet quickly in the direction of the stocks of the receiver than The roll of this portion of the sheet is bent as a result of setting to the next sheet. The combination of longitudinal injection pipes with suction elements allows, in addition, to install suction elements only on the lateral sections of the receiving stocks, since all other surfaces are exposed to sufficient pressure from the longitudinal injection pipes. The compressors needed to influence the injected air from the longitudinal injection pipes are used simultaneously to create a suction flow in the suction elements, so that when the proposed device is evaporated, the use of other KCwnpeccopoB is eliminated, ria FIG. 1 schematically represents a sheet with suction elements ,side view; Fig, 2 - the slipway of acceptance without transporting elements, top view; FIG. 3 shows another arrangement of the attachment of the elements with respect to the suction roller; ria of FIG. 1 shows a sheet-ejection device with a receiving berth 1, in which the front and rear stops of the sheet 2.3 and the chain circle 4 with a carriage with grippers 5 are located. The chain wheel 4 is guided through the front chain deflection chain wheel b. Above the slipway receiving unit 1, several adjacent longitudinal delivery pipes 7 are located above the sheet feeding line with nozzles 8 directed to the receiving slipway 1. At the rear edge of the receiving stocks 1, in the area of both side edges, trailing elements 10 are located on the traverse 9 and displacement, suction., the hole of which, provided with a cloth 13 and directed to the village of receiving 1, is located predominantly above the upper edge of the stocks. In front of the suction elements 10, in the feed direction of the sheets, there is a suction roller 12 consisting of a shaft of the suction roller 12.1 and rings of the suction roller 12.2., Shifting 1 on the shaft of the suction roller 12.1. As shown in FIG. 1, the suction elements 10 are located between the rings of the suction roller 12.2 and under the suction roller 12.1, rio it is also possible (FIG. 3) to place the suction elements 10 under the rings of the suction roller 12.2. so that the rings of the suction roller can be displaced to any position. The longitudinal delivery pipes 7, with the suction elements 10 and the suction rollers 12, are connected in a known manner to air supply devices presented only for the suction elements 10 of the elements 10. The principle of the device is as follows. From the carriage with grippers 5, sheet 14 is fed through the slipway of Acceptance 1, is released and placed on the slipway of acceptance 1. When it is fed over the slipway of acceptance 1, sheet 14 is sucked in and pulled up by the rings of the suction roller 12.2. After opening the grips of the carriage with the grips 5, the sheet from above is partially exposed to forced air exiting from the nozzles. 8 longitudinal delivery pipes 7, so that the sheet 14 under the action of forced air is squeezed onto the slipway of acceptance 1 from the inside to the outside while aligning the air cushion. At the same time, in the suction elements 10, a discharge is created and, through the suction hole 11, the air in the rear section at the side edges of the receiving stocks 1 ,, is sucked under the sheet 14, so that the sheet 14 and in the rear section after jumping off the rings of the suction roller 12.2 rapid movement in the direction of the receiving stocks 1. In order to prevent the falling sheet 14 from engaging the suction element 10 and the same, in order to avoid suction closure of which the openings 7 are drawn in by the intake air, it is controlled on a coherent basis. Suction air is supplied if the sheet 14 is an integral part of receiving stocks 1; it is not supplied if the back edge of the laid out sheet 14 has almost passed the suction inlet 11 of the suction elements 10, the wire mesh 13 at the suction inlet 11 prevents the part of the sheet 14 from being drawn into the suction element 10. If necessary, smearing the rings of the suction roller 12.2 on the suction roller shaft 12.1, The suction elements 30, as can be seen from FIG. 1, are deflected around the cross bar 9, or the device is constructed in accordance with FIG. 3 in such a way that the rings of the suction roller 12.2 can be shifted to any position over the suction elements, an invention according to the results of an examination carried out by the Office for the Invention of the German Democratic Republic.
