Definitions

  • the invention relates to a device for supplying an ink fountain of an inking unit assigned to a printing press according to the preamble of claim 1.
  • shut-off elements and an associated drive device each form a structural unit which is completely changed when the color is changed. Such an assembly is therefore required for each ink fountain and color. This results in a high structural effort.
  • Another disadvantage is the high weight of the units mentioned, which causes an increased amount of work when changing colors. The known arrangements therefore prove to be not economical and user-friendly enough.
  • a printing machine is known from EP-A2-0359957, on which a chamber doctor blade and an ink supply device can be detachably fixed.
  • a device for applying a measured amount of liquid paint to a color sample card for stains, cosmetics etc. in which a pump of a paint supply device can be fixed interchangeably to a stationary shut-off device.
  • a device for mixing several colors to a predeterminable color tone is known, individual components being provided in which a color component is stored and circulated, and from which the color components can be dispensed for mixing.
  • the individual elements can be removed and replaced for maintenance and care.
  • the shut-off elements are each attached to a movable line section which can be coupled to the assigned color source by means of a quick-release fastener, which makes it easier to carry out the color change.
  • a stationarily arranged distribution head can be provided, which can be loaded with the assigned color and is provided with a plurality of connection nipples, each of which forms a color source and is assigned to the assigned consumers. This allows a very compact arrangement to be achieved even if several adjacent color consumers are to be supplied.
  • the drive device can be coupled to the associated shut-off elements in the manner of a plug-in coupling ensures that the shut-off elements automatically come into and out of the drive connection when they are attached to or removed from the drive device.
  • shut-off elements can be releasably fixed to the housing of the drive device by means of a latching lock. Accordingly, the drive elements can be easily attached or detached by snapping in and out, which makes the color change very easy.
  • the latching lock can expediently have, on the one hand, provided leaf springs provided with latching cams, the latching cams of which can be latched into associated latching notches provided on the other. This results in a particularly simple and clear construction combined with simple and easy handling.
  • the printing machine unit on which FIG. 1 is based consists, in a manner known per se, of a machine frame 1 on which the printing unit and the ones assigned to it Aggregates are included. In the example shown, it is intended to be a double printing unit, of which only the lower plate cylinder 2 with an associated rubber cylinder 3 are shown.
  • An inking unit 4 is assigned to each plate cylinder 2. This contains, among other things, an ink fountain 5 from which an immersion roller takes 6 ink.
  • the color boxes 5 are pumped with the color to be processed in each case from large containers not shown here.
  • permanently installed ink lines 7a, 7b leading to the individual printing press units are provided.
  • Such a color line 7a or 7b is provided for each color.
  • the color lines 7a, 7b each end at a distributor head 9 provided with a plurality of connecting nipples 8a, 8b, which can be fastened to the machine frame 1, as indicated here by a console 10.
  • the distributor heads 9 assigned to the individual colors have a connection nipple 8a or 8b for each ink fountain 5 of the assigned machine unit.
  • the desired color is removed from the assigned connection nipple 8a or 8b and passed into the ink fountain 5.
  • filling devices assigned to the ink fountains 5 are provided, which are used alternatively.
  • Such a filling device is provided for each ink fountain and ink.
  • These filling devices contain a filling tube 11 which ends above the ink fountain 5 and is attached to a shut-off element 12, for example a ball valve, one of which Movable hose section 13 comes off, which can be connected by means of a quick-release fastener 14 to the desired connection nipple 8a or 8b.
  • the color level in the ink fountain 5 is measured and kept constant by opening and closing the shut-off element 12.
  • a drive device 15 is provided, which can be designed as a so-called rotary drive.
  • the filler pipe 11 together with the shut-off device 12 and the hose section 13 are changed.
  • the drive device 15 remains in position. This is arranged in a stationary manner, ie permanently assigned to the assigned consumer. In the example shown, the drive device 15 is fastened to a cross member 16 of the machine frame 1. However, it would also be conceivable to accommodate the drive device 15 together with the distributor heads 9 on one and the same holding device. Only one drive device 15 is required per consumer, that is to say here per ink fountain 5, to which the shut-off element 12 used in each case can be detachably attached and can be coupled in terms of drive.
  • the shut-off device 12 used, together with the filler pipe 11 and hose section 13, is carried in the installed state by the drive device 15 which is fixedly arranged in the machine, so that no additional machine-side support is required.
  • a suitable holding device and a coupling device are accordingly required for connecting the drive device 15 and the shut-off device 12.
  • the shut-off devices 12 are fastened to a support profile 17 formed here by a rectangular tube section, which supports opposite leaf springs 18, the ends of which project beyond the support profile 17 and are provided with locking cams 19 formed by inwardly bent bends are.
  • the housing of the drive device 15 is provided on the side assigned to its output 20 with a mounting foot 21, for example formed by strips flanking the output 20, to which the carrier profile 17 can be attached.
  • the mounting foot 21 is provided on the sides associated with the leaf springs 18 with roof-shaped inclined flanks, so that the locking cams 19 associated locking notches 22 result.
  • To attach the shut-off element 12 it is attached to the drive device 15 such that the locking cams 19 come into engagement with the locking notches 22.
  • a holding device designed as a latching lock
  • a magnetic connection or a bayonet lock or the like could of course also be provided.
  • the butt joint between mounting foot 21 and support profile 17 can be provided through pins 23 which are fastened here to the mounting foot 21 and can be brought into engagement in associated bores 24 of the upper web of the support profile 17.
  • the shut-off device 12 which can be fixed here by a snap lock on the drive device is driven with the output 20 of the drive member 15 in the manner of a plug-in coupling coupled, which can be brought in and out of engagement in the same direction as the holding device designed as a latching lock in the example shown, so that both the holding device and the coupling device can be brought in and out of engagement practically with the same handle.
  • the shut-off elements 12 are each provided with a drive stub 25 which passes through the associated support profile 17 and has a plug-in coupling element, here in the form of a square 26, at its end projecting above it.
  • the output 20 of the drive device 15 has a square recess 27 forming the associated plug-in coupling element, into which the square 26 can be inserted when the shut-off element 12 is attached to the drive device 15, as indicated in FIG. 2 by an arrow.
  • the shut-off device 12 associated with the previous color including filler pipe 11 and hose section 13, are simply removed from the drive device 15 by pulling them off and the quick-release fastener 14 is released. Then the shut-off device assigned to the new color, together with the filler pipe and hose section accommodated thereon, is held on the drive device 15 by sliding it on and brought into drive connection, and the quick coupling 14 is connected to the assigned connection nipple 8a or 8b. Since the drive device 15 remains in position, there are comparatively light exchange units in terms of weight, which can be easily handled. Since the drive device 15 per ink fountain only once required, there is also comparatively little effort.
