Definitions

  • the invention relates to a device for receiving a roller journal of a roller in the printing unit of a rotary printing press, the roller being arranged in the installed state almost axially parallel with respect to two further rollers of the printing unit and being in contact with the guide surfaces of both rollers.
  • An inking unit for rotary printing presses is known from the prior art, DE 33 42 853 C2, which can be converted from newspaper printing to commercial printing by installing additional components.
  • end shields are provided, in which the transfer rollers are received.
  • the adjustment of the roller gap between one of the transfer rollers and an application roller takes place via a pressure screw and is at the individual discretion of the printer.
  • Adjustable roller bearings of the inking rollers and transfer rollers are disclosed here. Sliding blocks are fastened in the side walls so that the bearing body can be moved by turning an adjusting screw in order to vary the contact force in the contact zone. The size of the contact force is indicated by the compression path of a spring or a spring assembly. After determining the setting position to generate a defined contact force, the bearing body is attached to the side wall in the determined position. This device does not automatically adapt the contact zone to parameters that change during machine operation.
  • the object of the invention is to optimize a roller bearing in such a way that an automatic adjustment of rotating bodies is achieved while the arrangement can be used universally.
  • the screw-in element can be moved up to a predetermined fixed position in a bearing body. On the one hand this prevents incorrect settings by the printer, on the other hand there is no need for countering. Set-up times for adjustment can be drastically reduced.
  • the bearing body can be attached in any orientation in several positions in the inking unit or printing unit. This allows universal use of the device for receiving roller journals and avoiding them elaborate adaptation constructions. Furthermore, the bearing body has guide cams. As a result, the weight of the roller can be absorbed by the lower guide cams in an adjustment in which the dead weight of the roller is to be eliminated. For example, it can be placed exactly between two rubbers by the contact force exerted by the pressing element.
  • the guide cams have inner surfaces whose spacing from one another is greater than the diameter of a roller journal to be accommodated. In this way, it can be achieved in an advantageous manner that the picked-up roller can shift laterally during a shut-off movement - for example the application rollers. With the appropriate installation position, the roller can align itself exactly between the rubbers.
  • a cavity is formed between the pressure element and the screw-in element, which receives a compression spring.
  • This component generating the contact force can also be designed as a spring assembly; the use of disc springs is also conceivable.
  • the adjusting forces are adjusted by using compression springs with different spring characteristics or by changing the installation space for the compression spring either by using a modified pressure element or by installing a modified screw-in element.
  • the contact forces between rollers at certain installation points in the inking unit can be adjusted by installing appropriately designed and preassembled devices for receiving rollers. A time-consuming adjustment when installing the rollers by the printer is not necessary. Due to the uniform structure of the device for receiving roller journals at various installation points in the inking unit or printing unit, the printer quickly gets used to it the handling of this device, for the operation of which only a tool is necessary.
  • Fig. 1 shows a device according to the invention for receiving rotary bodies in a vertical installation position.
  • a bearing body 1 is provided with a thread in its upper area, while it has two guide cams 1a in its lower area.
  • a roller pin 4a of a roller 4 is located between mutually facing inner surfaces 1b of the guide cams 1a.
  • the lateral surfaces of two rubbers 9, 10 serve as guide surfaces for the roller 4.
  • a screw-in element 5, which has a cavity 5a, is inserted into the thread made in the upper region of the bearing body 1.
  • a pressure element 6 is movably arranged in the cavity 5a.
  • the pressing element 6 has a slim neck region 6a in addition to a head region 6b with an enlarged diameter. The pressing element 6 is secured against falling out by the locking pin 7.
  • a compression spring 8 is supported on the one hand at the upper end of the cavity 5a, while its opposite end abuts the head region 6b of the pressing element 6.
  • the geometry of the cavity 5a can be achieved by installing a pressure element 6 same overall length, which has a shortened or extended head region 6b, can be varied, whereby a change in the positioning forces can be achieved.
  • the screw-in element 5 which is designed in the upper area with a common wrench size, is screwed into the bearing body 1 during assembly in the bearing body 1 until the collar rests, as a result of which countering is not required.
  • the roller pin 4a of the roller 4 lying between the inner surfaces 1b of the guide cams 1a is positioned between the rubbers 9, 10 by the head region 6b of the pressing elements 6 with a defined preload and a defined roller contact width.
  • the roller contact width is in turn determined by the compression spring 8 acting on the head region 6b of the pressing element 6. To remove the roller 4, only the screw-in elements 5 in the bearing body 1 have to be turned back until the roller pin 4a can be passed between the guide cam 1a and the pressing element 6b.
  • the cavities 5a of the screw-in elements 5 can be filled with grease be provided. Thereafter, the device for receiving rollers 4 is to be regarded as maintenance-free.
  • FIG. 3 finally shows a front view of a device according to the invention for receiving rollers.
  • the bearing body 1 is connected to the side wall 3 by means of screws 2, the screw heads lying in counterbores in the bearing body 1.
  • This view can be both a vertical and a horizontal orientation in the machine.
  • the bearing body 1 can also be installed inclined at a certain angle in the machine.
  • transfer rollers as well as dampening or ironing rollers can be easily and safely accommodated in one printing unit.
  • these could also be adapted, for example via a threaded spindle, to larger diameters of roller journals 4a.
  • the simple structure of the device and the quick assembly allow a versatile universal use of the device according to the invention for holding rollers, both on the drive side and on the operating side of a processing machine.
  • the universal use of the device according to the invention for receiving rollers is favored by the symmetrical structure of the bearing body. This ensures good accessibility, ease of use and use on the drive and operator side.
  • bearing body 1 allows only one storage configuration to be used instead of many complex adaptation designs. Since the storage configuration according to the invention consists of only a few Components exist, the manufacturing costs are lower; it is also possible to use only the bearing according to the invention for each printing unit or inking unit for the storage of transfer rollers. This serves to standardize and save set-up time when adjusting the rollers. The component expansions caused by heating during longer machine running times can be automatically compensated, so that the service life of the components - for example by reducing the flexing work in the roller contact zones - and by reducing the component stresses can be increased considerably.
