Definitions

the invention relates to a device for the remote-controlled actuation of clamping members of a turning device, in particular on sheet-guiding cylinders and on the side walls of rotary printing presses.
a device for adjusting the rotational position of a cylinder of a turning device and for axially displacing an actuator for converting the gripper control on this cylinder of a sheet-fed rotary printing press is known from the prior art DE 38 14 831 C1.
a threaded sleeve designed with a socket wrench is rotated in order to reduce or completely eliminate the clamping force exerted on the pressure lever by a spring assembly via a pressure ring.
a double lever which can be actuated via an annular groove, serves to interrupt the supply circuit when the clamping between the fixed and adjusting gear is removed and to close the supply circuit when the clamping between the fixed and adjusting gear is restored.
a disadvantage of this device is the fact that on the one hand manual operation is required to release the clamp, and on the other hand that an electrical circuit is interrupted mechanically.
the object of the present invention is to create the conditions for a remotely controllable clamping device made of standardized, compact components.
actuators which can be acted upon by pressure medium are arranged on movable, at least one-piece push rods which move a transmission element in such a way that the clamps generated by energy accumulators become ineffective.
a further embodiment of the solution according to the invention provides that the movable, at least one-piece push rods are rotatably received by actuators which can be pressurized to be fixed against rotation.
actuators which can be pressurized to be fixed against rotation.
bearing elements can be inserted into the actuators which can be pressurized. This means that they can be used on both rotating and non-rotating push rods without changing the geometry of the actuators. This means that they can be used universally and can be produced in large numbers, which reduces manufacturing costs.
a further embodiment of the idea on which the invention is based provides that the actuators which can be acted upon by pressure medium are received directly by a movable, at least one-part pressure rod.
separate bearing elements can therefore be dispensed with, while the configuration of the actuators can be retained for this application.
actuators which can be actuated indirectly by a pressure medium are arranged on a movable, at least one-part push rod and move a transmission element in such a way that the clamps generated by the energy store become ineffective. Since actuators that can be actuated indirectly via a pressure medium are used, small and compact hydraulic or pneumatic actuators can be used by appropriately dimensioning the components with regard to pressure areas and leverage ratios - which are representative of other parameters.
One embodiment of this solution concept provides that the actuator which can be actuated indirectly via a pressure medium receives an eccentric bolt which is connected to an actuating cylinder via a lever. In this variant, the periphery of the pressure generation can be attached outside the clamp to be actuated.
a further development of this solution concept provides for an axially movable, at least one-piece push rod which is rotatably mounted in a bolt holder. Furthermore, the bolt holder has a radial bearing and is supported by an axial bearing when the eccentric bolt is turned at a stop.
the spring force of an energy accumulator can be removed with a minimal switching force applied at the end of a lever, but a small actuating force, so that an adjustment operation can be carried out.
Fig. 1 shows a section through pressure-actuated, remotely actuated actuators on a rotating pressure rod.
pressure levers 5 press the adjusting gear 3 received by a pin attachment 2 against a fixed gear; they act on the ring surface 4.
the pressure levers 5 are supported on a support plate 7 which is screwed to the pin extension 2 by screws 6.
a package of springs 12 is arranged, which generates the pretensioning force necessary to maintain the clamping.
this acts on the lower lever arms of the pressure levers 5, as a result of which these are supported on the support plate 7 via a cam on the rear of the pressure levers 5.
the fixed gear 1 and the adjusting gear 3 are clamped against one another with an increased clamping force corresponding to the lever ratios.
a pressure lever 8c is provided in the interior of a cylinder 8 and is mounted on a hinge pin 8d. If the push rod 9 presses against the push lever 8c, it clamps the adjusting slide 8a in position on the cylinder 8 via the pull bolt 8b.
a piston 20 is accommodated on the push rod 9 by an axial bearing 17 and a radial bearing 19, which piston is accommodated in a housing 24 in a rotationally fixed but axially displaceable manner.
the housing 24 accommodates an axial bearing 18 in a recess on the push rod side and is connected in a rotationally fixed manner to the side wall of the machine via an anti-rotation device 25.
the housing 24 has an annular groove 21, in which a sealing element 22 is embedded.
the boundary wall 23 of the piston 20 forms a boundary of a pressure chamber 30.
the housing 24 has a feed line 26 for a pressure medium and has a further sealing element 27 which, together with the sealing element 22, the pressure chamber 30 between the components 20, piston 20, which are movable relative to one another and housing 24, seals and allows pressure to build up. With its boundary surface 28, the housing 24 completes the pressure chamber 30, which runs in an annular manner between the piston 20 and the housing 24 and is acted upon by a pressure medium via the feed line 26.
the recess for receiving the axial bearing 18 is limited by the projection 29 on the housing 24.
the pressure build-up takes place between two non-rotatably arranged components, namely the piston 20 and the housing 24, the sealing of which from one another is not a problem.
an overpressure builds up in the pressure chamber 30 formed by the boundary surfaces 23 and 28.
the piston 20 is supported by the axial bearing 17 on the stop 15, which is secured by the lock nut 16.
the housing 24 moves towards the spring assembly 12 in the axial direction, corresponding to the build-up of the excess pressure in the pressure chamber 30.
the machine is protected during the changeover phase by a pressure switch integrated in the supply line 26 of the pressure medium, which keeps the supply circuit interrupted in the pressure build-up, so that the machine does not start up when the clamp is open.
a limit switch linkage can thus be omitted.
Fig. 2 shows a section through a device flanged to a storage drum for the remote-controlled actuation of clamping members.
a package of springs 12 is supported on a housing 35.
the housing 35 is flanged to the storage drum 31 by means of screws 34.
the spring assembly presses a push rod 32 via a shoulder 32a against a - with respect to a cam for support - longer lever arm of a pressure lever 33.
the shorter lever arm of the pressure lever 33 clamps the jacket 31 a of the storage drum 31 against the stop 31 b on the pin of the Storage drum 31 is attached.
the piston 20 and the housing 24 are accommodated on the push rod 32 via the axial bearings 17 and 18 and the radial bearing 19 - analogously to the illustration shown in FIG. 1.
the piston 20 is supported on the axial bearing 17 on the stop 15, which is secured by a lock nut 16.
the housing 24 connected to the side wall by the anti-rotation device 25 receives the piston 20 in a rotationally fixed but axially displaceable manner.
the pressure chamber 30 is formed by two annular boundary surfaces 23 and 28 of the piston 20 and the housing 24, respectively.
the pressure chamber 30 is suitably sealed by the sealing element 22 in the annular groove 21 of the piston 20 on the one hand and by the sealing element 27 of the housing 24 on the other hand for a pressure build-up.
FIG. 1 A comparison with FIG. 1 shows that the geometries of the actuators, that is to say the piston 20 and the housing 24, are identical; this results in a universal usability of these components when used on several components of a turning device. Furthermore, when the storage drum and the turning drum are equipped with the device according to the invention, a simultaneous actuation of several components can be achieved.
the embodiments shown in FIGS. 1 and 2 can also be used to retrofit machines with the device according to the invention, which have already been delivered, so that the rotary rationalization potential inherent in the device according to the invention can be used with these delivered rotary printing machines.
FIG 3 shows a section through a device for the remote-controlled actuation of a clamp for a tooth segment, which is adjustably mounted on the side wall of a rotary printing press.
a bell-shaped body 36 - or a correspondingly shaped bracket - is located on the side wall 38 of a rotary printing press.
the bell-shaped body 36 can be fastened to the side wall 38 by screws 37; in order to save installation space, it can also be embedded in the latter, whereby a shortening of the push rod segment 39 can be achieved.
At least one spring 12 is accommodated on the push rod segment 39 between the shoulder 40 and a stop 41 fixed to the housing, which limits the adjustment path 14.
the piston 20 is connected to the bell-shaped body 36 by screws 44, while the housing 24 is centered on the end of the push rod segment 39 and rests with a shoulder on the shoulder 40.
the push rod segment 39 is provided on its rear part facing the toothed segment 43 with a nose 42 which, when the push rod segment 39 moves in the axial direction, clamps the toothed segment 43 to the side wall 38 or releases it for adjustment.
pistons 20 and housing 24 are provided with sealing elements 22 and 27 which are received by annular grooves in order to ensure the pressure build-up in the pressure chamber.
FIGS. 1 to 3 installation cases for the housing 24 and the piston 20 are shown, which are received in them by rotating pressure rods 9, 32 via bearing elements, while in FIG. 3 an arrangement on a non-rotating pressure rod segment 39 is shown.
Fig. 4 shows a section through a pneumatically actuated device. Deviating from the previously described embodiments of the device according to the invention, components with larger pressure chamber boundary surfaces are shown in this variant.
a rotating pressure rod 9 is rotatably received in a housing 48 via radial bearings 19, while a piston 46 acts on a pressure sleeve 45 via an axial bearing 47.
the pressurization of the pressure chamber 30, on the one hand causes the housing 48 to rest against the stop 15 via the axial bearing 17, while, on the other hand, the piston 46 moves the pressure sleeve 45 against the disk 11 via the axial bearing 47.
the load applied by the springs 12 to the pressure lever 5 is released and the rotational position of the adjusting gear 3 can be adjusted.
This variant is intended for large-scale applications in which compressed air is already used in the periphery and there is sufficient installation space.
the possible uses are considerably expanded by a combination with a hydraulically loadable variant.
FIGS. 5 and 6 finally show a section or a top view of actuators which can be actuated indirectly via a pressure medium.
a pin bearing 52 is rotatably supported by radial bearings 19. Furthermore, an axial bearing 17 is provided between a threaded ring 50 and the bolt bearing 52.
the pin bearing receives an eccentric pin 53 via roller bearings, which is equipped with a roller 54 on each end.
the eccentric bolt 53 is provided with a lever 55, at the end of which there is an adjusting movement by a commercially available adjusting cylinder 56.
An actuating body 51 is centered on the pin bearing 52, the eccentrically mounted rollers 54 abutting on its end faces.
bores 57 are provided in the actuating body 51 and in the pin bearing 52, which allow access to the threaded ring 50.
the lever 55 pivots, triggered by pressurizing the actuating cylinder 56, the eccentric bolt 53 is rotated.
the rollers 54 act on the end faces of the actuating body 51 and move it - relative to the pin bearing 52 and the push rod 49 - in the axial direction.
a thrust sleeve 13 is correspondingly axially displaced via the axial bearing 18, so that this - similar to the above-outlined versions - can release the preload of a spring assembly and release the execution of an adjustment operation.
56 large actuating forces can be generated in this variant, which can be actuated indirectly via a pressure medium, with small actuating cylinders.
