DE7522893U - DEVICE FOR PULLING A WEB OF MATERIAL, PREFERABLY INTO ROLLER ROTARY PRINTING MACHINES - Google Patents

Description

Device for drawing in a web of material, preferably in web-fed rotary printing machines.

The innovation relates to a device

for pulling in webs of material, preferably in web-fed rotary printing machines.

Devices for drawing in webs of material in roller rotary printing machines have become known. As a means of transport e.g. endless, driven, flexible tapes. Rail-bound motor vehicles have also been proposed as a means of transport (DT-PS 20 21 246).

DT-OS 22 41 127 describes the drawing in of a paper web into a web-fed rotary printing press. Here finds a finite, driven, flexible, metallic one Indentation element application. It is necessary to use the feed element to lead continuously. These guides take up space and can have relatively large radii of curvature not fall below. In addition, bind with a longer feed path a large number of drive motors running synchronously with one another are necessary. The number of drive motors is depending on the length of the feed element. To change the direction of movement of the feed element are controllable Points provided.

The innovation is based on the task of a soft one Infeed device for webs of material, preferably in web-fed rotary printing presses, in which the finite Feeding element does not need to be guided in fixed, continuous guides, and in which there is no increasing cost Switches are needed.

The problem is solved by the subject matter of the characterizing part of claim 1 .. *

The advantages achieved with the innovation exist in particular that a simple pulling in of a web of material around the smallest radii, through the narrowest gaps and over long distances becomes possible. This enables a material web to be drawn in automatically even with the most difficult material web guides available. Since this pull-in device requires little space, it can also be used in confined spaces Find. Furthermore, there are no mechanical rails, but Guide rollers or short guide pieces that can be attached at will only necessary at certain intervals; therefore, the retractor can be installed with little installation effort. In addition, the use of the proposed pull-in device increases the accessibility of the web-fed rotary printing press not discounted. The conveying means of the pull-in device is not a hindrance even if it is tight

In the schematic mode of operation of the device for pulling material sheets in web-fed rotary printing presses shown in FIGS. 1 and 2, a finite conveying means A3 runs through, for example, the offset printing units t and 2. The conveying means Al bit A ' _t B, C, D, E, F, G , H, K, / starts in memory devices 3.1 ^b 3.4 ^s i- or suspension devices in the 4.1 to 4.6 and finishes in each of the memory devices 5.1 to 5.5 or in the suspension devices 6.1 to 6.5. The storage devices 3.1 to 3.4, 5.1 to 5.5 can each be designed as a coil 7. Other types of storage can of course be used. The storage devices 3.1 to 3.4, 5.1 to 5.5 are driven by the drive means 8.1 to 8.4 or 9.1 to 9.5. Electric, hydraulic or pneumatic motors, for example, can serve as drive means 8.1 to 8.4, 9.1 to 9.5, which are used to feed the conveying means into the storage devices. They are mounted in the racks or frames 11 of the web-fed rotary printing machine by means of a flange 10. The receptacles 12 for the bobbins 7 are advantageously designed as so-called quick-change drives so that the bobbins can be quickly exchanged or even relocated to another location.

The process of pulling in a web of material is briefly on Figures 1 and 2 outlined.

The beginning of the web of material 20.1, 20.2, 20.3 of a supply roll 24.1, 24.2, 24.3 is beveled in such a way that a tip is created that fits into one of the slots 21 of the ribbon-shaped Conveyor 16 or a material web hanger 22 of the rope-shaped conveyor 17 can be suspended. In During this phase, the conveyor and the machine are at a standstill. Suitable electrical circuits are used to initiate the Pull-in commands the clutch 19. ■ to 19.S activated so that from the drive, e.g. from ... the draw roller 18.1 to 18.5, to the Drive roller 14.6 to 14.10 of the conveyor A4,?, E, F, L a through drive with a preset torque is available.

18.5. If the assigned clutch 19.1, 19.5 is coupled through, the drive roller 14.6, 14.10 - supported by the pressure rollers 15 - will drive the conveying means AU A3 + A4 _r G + K + L with practically no slip. The drive means eg 8.1, 8.4 coupled to the delivering storage device, e.g. 3.1, 3.4, no longer exerts any moment on the conveying means A1 + A3 + A4, G + K + L in this phase, while the one coupled to the receiving storage device, e.g. 5.1, 5.5 Drive means 9.1, 9.5 is controlled so that it drives the storage device, for example a coil 7. As a result, the conveying means A1 + A3 + A4, G + K + L conveyed synchronously with the draw roller, for example 18.1, 18.5, is wound up by a reel 7, for example. With the movement of the conveying means A1 + A3 + A4, G + K + L along the preselected material web path, for example AA, the material web attached to it, for example 20.1, is of course transported on a predetermined path through the machine. When the tip of the material web has reached the desired position in the machine, it is removed, for example, from the slot 21 of the stopped conveyor A1 A3 A4, GRL and guided by hand, for example over the funnel of a folder. When the beginning of the material web is inserted into the folding unit via the funnel, the drawing-in process of the material web is complete.

Every completed pulling-in process is the conveyance
