Definitions

  • the invention relates to a device for inserting a push-in carriage carrying a printing roller into a printing press.
  • Insert trolleys of this type are usually used to insert pressure rollers between the side frames of a printing press in such a way that the shaft journals engage in elongated holes or recesses in the side frames, in which these can then be connected to the journal bearings.
  • the slide-in carriages are used to remove printing rollers from a printing press after their shaft journals have been released from the journal bearings, as is required, for example, when changing printing rollers.
  • the handling of the slide-in carriage with the pressure roller placed on it for the insertion or discharge thereof requires a great deal of skill on the part of the operating personnel, who must prevent the slide-in carriage and the shaft journals of the pressure roller from colliding with the side frames or other parts of the printing press in order to prevent damage from corresponding impact loads.
  • Practice shows that despite great attention from the operators, lighter and also more serious collisions of the insert carriage and the shaft journal of the printing roller with parts of the printing machine cannot always be avoided.
  • this object is achieved in a device of the generic type in that the slide-in cart is provided with two sliding blocks or with two guide rollers rotatably mounted about vertical axes, which can be inserted into a longitudinal groove of a guide rail, which is between a pivoted-out slide-in position for the slide-in cart and one pivoted position is pivotable, in which the shaft journals of the printing roller engage in recesses in the side parts of the printing press frame, in which they can be connected to the journal bearings.
  • the device according to the invention certainly prevents collisions of the slide-in carriage and the printing roller with parts of the printing machine which lead to damage.
  • printing rollers can be guided out of the printing machine without collision.
  • the slide-in carriage held in the guide rail can remain in its position retracted into the printing press during the printing operation, so that it is already in the correct position for the purpose of later removal of the printing roller.
  • the slide-in cart is fastened to its base frame, the one side of which protrudes levers which carry the sliding blocks or guide rollers at the lower free ends of vertical axle journals.
  • the insertion trolley is expediently provided with four wheels which are mounted in fork-shaped bearing blocks which are freely rotatable about vertical axes, the axes of rotation of the wheels being at a distance from the vertical axis (so-called tea trolley wheels).
  • the slide-in carriage can be provided at a distance from one another with V-shaped trestles for receiving the axle journals of a pressure roller, one flank of which can be folded down to release the pressure roller. Furthermore, the relative spacing of the recordings can be adjustable.
  • the slide-in carriage and / or the printing machine frame is provided with rollers which can be rotated about vertical axes and which form limiting stops.
  • the slide-in carriage is then pushed forward in the longitudinal groove until it rolls with its corresponding rollers Sliding surfaces of a side part meet or until guide rollers located on a side part are supported on frame parts of the slide-in carriage.
  • these rollers also take over a guide and ensure a low-friction insertion.
  • the guide rail is articulated to the printing machine frame by two links.
  • These links preferably have different lengths in such a way that they guide the guide rail between its pivoted-in position, in which it is at right angles to the side frames of the printing press, and its angular, pivoted-out position, in which the guide rollers of the sliding blocks can be inserted into the guide groove.
  • a drive is provided for pivoting the guide rail.
  • This swivel drive further facilitates the correct insertion and removal in that the operators only have to insert the insert carriage into the swiveled-out guide rail.
  • the subsequent pivoting-in movement can then take place automatically, the operator merely having to take care that the slide-in carriage remains fully inserted into the longitudinal groove during the pivoting of the guide rail.
  • the drive expediently consists of a pressure medium-piston-cylinder unit which is articulated on the one hand in a link and on the other hand on the printing press frame.
  • the two side frames 1 of a printing press are connected to one another by a hollow profile 2.
  • the hollow profile 2 carries at both ends an upwardly pointing support arm 3, some of which are embedded in the side frames 1.
  • the side frames 1 are provided with elongated holes which receive the roller journals 4, the support arms also having mouth-like receiving recesses 6.
  • the design of the devices by means of which the bearing pins 4 are locked in the elongated holes 5 and the recesses 6 need not be discussed in more detail, since this is known prior art.
  • Spacer rollers 17 connected to the insertion trolley 15 and a further insertion roller 18 connected to a side frame 1 ensure that collisions of the insertion trolley with the side frames 1 are avoided during the pivoting-in movement.
  • the operator only needs to exert slight pressure in the direction of arrow A on the slide-in cart.
  • the slide-in carriage 15 which is only indicated in FIGS. 1-3, is shown more clearly in FIGS. 4 and 5. From these figures it can be seen that the slide-in carriage 15 consists of a base frame 20 carried by wheels 19, on which upwardly directed side walls 21 are firmly attached. The two side walls 21 are connected to one another via an upper cross member 22 and a lower cross member 23. On these cross members are two mutually adjustable supports 24 and 25 in different Positions determined to each other, each having a receiving prism 26 for the roll neck 4. After inserting the roller journals 4 into the elongated holes 5 or the receiving recesses 6, the parts 27 of the prisms 25 can be folded away about the axis 28, so that the insert carriage 15 can be moved out again. This driving out is not absolutely necessary, since in a known manner the roller journals after insertion into the elongated holes 5 and the receiving recesses 6 are raised by locking elements by a small amount and thus they no longer have a direct connection to the receiving prisms 26.
  • FIGS. 4 and 5 it is indicated that the supports 24 and 25 are held by a dovetail guide 29 provided in the cross member 23 and can be locked in different positions by means of screws 30 and bores made in the cross member 23.
