Description

  • The The invention relates to a coupling arrangement for a printing press according to the preamble of claim 1.
  • At Printing presses require drive power, for example on a printing machine cylinder by a same associated Drive is provided, if necessary, to another press cylinder transferred to, in which case coupling arrangements are used. With such Coupling arrangements make it possible two or more printing press cylinders or other aggregates To couple a printing machine on the drive side, so on a Press engine cylinder provided drive power at least another printing press cylinder or on another unit the printing press to make available. Likewise It may be necessary to mechanically interconnect multiple drives as needed to couple together to press cylinders or aggregates one To drive printing press or open couplings each associated Drive or shut down printing press cylinders or units separately to be able to. Under an aggregate of a printing press, all facilities unwinding, printing, conveying, turning, Cutting, drying, stapling, folding or perforating a substrate serve.
  • Out The practice known clutch assemblies for printing machines have at least one on a shaft portion of, for example, a printing press cylinder mounted clutch, wherein the or each clutch if necessary a drive-side connection between the shaft portion and provides a drive wheel mounted on the shaft portion, which with a drive wheel of an optionally be coupled printing press cylinder or a drive wheel of an optional unit to be coupled the pressure machine is engaged. With the clutch closed the drive wheel is engaged with the shaft portion and can so transferred the drive power of a shaft to another shaft. When open Clutch, on the other hand, is the drive wheel mounted on the shaft section except Engage with the same, so that then do not transmit the shaft power becomes.
  • The or any coupling mounted on a shaft section is included known from practice clutch assemblies each one mounted axially displaceable on the shaft portion, together with the shaft portion rotating coupling ring, wherein the axial displaceable coupling ring in a first axial position the respective drive wheel coupled to the shaft portion and in a second axial position the drive wheel decoupled from the shaft portion. The operation of the axially displaceable coupling ring takes place in known from practice Clutch arrangements via separately formed pneumatic cylinder or hydraulic cylinder, which the one for operation provide the axially displaceable coupling ring required axial force. The introduction of the axial force in the axially displaceable, itself rotating coupling ring takes place via separate bearings, so that the pneumatic cylinder or hydraulic cylinder of the rotary motion of the shaft portion is decoupled, and therefore the axially displaceable Coupling ring and the pneumatic cylinder or hydraulic cylinder designed as separate components are. In known from practice clutch arrangements are therefore the actual clutch and an actuating mechanism for the clutch decoupled from each other and realized by separate modules, resulting in a relatively large Design for the coupling arrangement results. In addition, a variety required by construction elements, so that the well-known from practice Coupling assemblies are relatively expensive.
  • Of these, Based on the present invention, the problem is based to provide a novel clutch assembly for a printing press.
  • This Problem is solved by a clutch assembly for a printing press according to claim 1 solved.
  • According to the invention axially displaceable coupling ring for movement of the same from the first axial position in the second axial position and / or by the second axial position in the first axial position pneumatically or hydraulically actuated, wherein a pneumatic medium or hydraulic medium for actuating the axially displaceable coupling ring via a rotary feedthrough in the shaft section insertable and over Holes integrated into the shaft section towards the shaft Coupling ring is conductive.
  • With the present invention, a clutch assembly for printing machines is proposed, in which the axially displaceable coupling ring of a clutch is actuated pneumatically or hydraulically, namely the fact that a pneumatic medium or hydraulic medium via integrated into the shaft portion holes in the direction of the coupling ring is conductive. The axially displaceable coupling ring thus assumes the function of the known from practice Kupplungsan Separate executed pneumatic cylinder, whereby the clutch function and the clutch actuation function are combined. As a result, a significantly shorter design for clutch arrangements can be realized.
  • short Designs are especially advantageous when on a shaft section several couplings are positioned next to each other. In this Case is it possible then due to the relatively short design all couplings in close proximity to a Position bearing of the corresponding shaft, so that eventual Bending of the shaft with increasing distance from the bearing stronger to bear, for the clutches or the associated drive wheels, the for example as gears or pulleys or sprockets can be trained stay almost without influence.
  • Preferably between the axially displaceable coupling ring and the rotating driven shaft portion positioned a hub, wherein the Hub on the one hand with the shaft portion and on the other hand with the Coupling ring is rotatably connected. Characterized in that the axially displaceable Coupling ring with interposition of a hub on the shaft portion is arranged, is an optimal axial guidance of the axially displaceable Coupling ring guaranteed. Furthermore, a torque from the shaft to the axially displaceable Transfer coupling ring securely become. about the hub is still a seal one of the axially displaceable Coupling ring limited pressure chamber for the pneumatic medium or Hydraulic medium, over which is the axial force required to move the coupling ring is provided, possible.

  • 6 3 is a sectional view through three shaft sections of three press cylinders to be coupled to one another using two clutch arrangements according to the invention, the clutch of the press cylinders being in the first and third gear planes.
  • Hereinafter, this present invention will be described with reference to FIG 1 to 6 described in more detail.
  • 1 shows a coupling arrangement according to the invention 10 for a printing press according to a first embodiment of the present invention, wherein the coupling arrangement 10 of the 1 a single on a shaft section 11 a printing press cylinder 12 mounted clutch 13 includes. At the shaft section 11 is in the illustrated embodiment, a cylinder stub of the printing press cylinder 12 , facing a wall 14 in which the printing press cylinder 12 via a movable and thus eccentric bearing 15 is stored, projecting laterally.
  • The coupling 13 has a coupling ring 16 , which under interposition of a hub 17 on the shaft section 11 is arranged axially displaceable. The hub 17 is non-rotatable or rotationally fixed with the shaft portion 11 connected and therefore rotates at the same speed as the shaft portion 11 , The axially movable coupling ring 16 is rotatable on the hub 17 stored, so that the axially displaceable coupling ring 16 rotated at the same speed as the shaft section 11 , As 1 can be removed, is the coupling ring 16 with the hub 17 via a positive interlocking 18 in engagement, wherein the positive toothing 18 on the one hand, the axial displacement availability of the coupling ring 16 opposite the hub 17 allows and on the other hand the Kupp development ring 16 in its circumferential position on the hub 17 fixed. Instead of the positive interlocking of the axially displaceable coupling ring may be rotatably connected with annularly arranged lamellae with the hub, the lamellae must be designed so that the coupling ring can be moved axially.
  • As already mentioned, the coupling ring 16 displaceable in the axial direction, namely between two axial positions. In a first axial position of the coupling ring 16 causes the same a coupling of a drive wheel 19 to the shaft section 11 , In a second axial position, however, a decoupling of the drive wheel 19 from the shaft section 11 , At the drive wheel 19 it may be a gear, a pulley, a sprocket or other rotatably mounted member that is capable of transmitting torque.
  • In the upper half of the 1 is the axially displaceable coupling ring 16 shown in the first axial position, in which the same the drive wheel 19 to the shaft section 11 couples. In the lower half of the 1 is, however, the axially displaceable coupling ring 16 shown in the second axial position, in which the same the drive wheel 19 from the shaft section 11 disconnects. As 1 can be removed, is the axially displaceable coupling ring 16 not directly with the drive wheel 19 engaged but rather via a drive wheel 19 assigned, fixed in the axial direction coupling ring 20 , In the first axial position, in which the drive wheel 19 to the shaft section 11 is coupled (upper half of 1 ), this are the axially displaceable coupling ring 16 as well as the fixed coupling ring 20 via a positive plan toothing 21 engaged. In the second axial position of the coupling ring 16 On the other hand, this is the planing 21 between the two coupling rings 16 and 20 separated. At this point it should be noted that the two coupling rings 16 and 20 instead of via the positive-toothed toothing 21 can also be coupled to each other with other form-fitting elements or via a frictional connection.
  • Between the rotation with the shaft section 11 connected hub 17 and the fixed coupling ring 20 or the drive wheel 19 is an in 1 schematized bearing 22 positioned, which may for example be designed as a rolling bearing. A bearing ring of the bearing is firmly connected to the hub, another bearing ring with the coupling ring and the drive wheel.
  • The coupling or uncoupling of the drive wheel 19 to the shaft section 11 takes place at the clutch 13 in that the axially displaceable coupling ring 16 between the two axial positions of the same is reciprocated, wherein the movement of the axially displaceable coupling ring 16 from the first axial position to the second axial position and / or from the second axial position to the first axial position in the illustrated embodiment is pneumatic. Instead of the pneumatic actuation, a hydraulic actuation can also be provided.
  • The axially movable coupling ring 16 that always coincides with the shaft section 11 rotates, limited together with the likewise rotating hub 17 in the embodiment shown, a pressure chamber 23 , in which a pressure can be built up to the axially displaceable coupling ring 16 against one of a spring element 24 provided spring force from the in the lower half of 1 shown second axial position in the in the upper half of 1 shown first axial position in which the drive wheel 19 to the shaft section 11 coupled to convict. A provision from this first axial position to that in the lower half of 1 shown second axial position of the coupling ring 16 in which the drive wheel 19 from the shaft section 11 is decoupled, carried by the spring force of the spring element 24 ,
  • Im in 1 shown embodiment, therefore, the axially displaceable coupling ring 16 to move it from the second axial position, in which the drive wheel 19 from the shaft section 11 is decoupled, in the first axial position, in which the drive wheel 19 to the shaft section 11 is coupled, pneumatically actuated, and in that in the pressure chamber 23 a pressure force is provided which is greater than that of the spring element 24 provided spring force. The return movement from the first axial position to the second axial position via the spring element 24 in which the pressure within the pressure chamber 23 is reduced. Of course, in the sense of the present invention, the axially displaceable coupling ring are pneumatically actuated from the first axial position to the second axial position, in which case the return movement from the second axial position to the first axial position is effected by the spring element. In this case, only the spring element must be repositioned. It is also conceivable to accomplish pneumatically the movement of the piston ring from the first axial position into the second axial position as well as from the second axial position into the first axial position via two pressure chambers. It should again be noted that instead of the pneumatic actuation also a hydraulic actuation can take place.
  • The introduction of the pneumatic medium into the pressure chamber 23 takes place in that via a rotary feedthrough 25 the pneumatic medium in the shaft section 11 is initiated and one in the shaft section 11 integrated bore 26 as well as one in the hub 17 integrated bore 27 in the pressure room 23 arrives. From the rotary union 25 is a fixed, outer housing part 28 shown on which via a connection 29 a pneumatic line can be connected.
  • For the purposes of the present invention, the axial position of the axially displaceable coupling ring 16 and thus the switching position of the clutch 13 queried. This is realized in that with the axially displaceable coupling ring 16 initiators 30 . 31 interact, which the edge position of the coupling ring 16 Interrogate. In each of the two axial positions and thus switching positions of the axially displaceable coupling ring 16 the same enters the sphere of action of one of the two initiators 30 respectively. 31 , so that over this the switching position of the clutch 13 can be detected. It is also conceivable to interrogate the clutch position indirectly, for example, by querying or monitoring the air pressure or by querying a pneumatic or hydraulic valve to control the air or hydraulic pressure.
  • In the 1 shown coupling arrangement 10 that only one on the shaft section 11 positioned coupling 13 includes, has a very compact design. This is realized by the fact that for the actuation of the clutch 13 or for the axial displacement of the coupling ring 16 required pneumatic medium or hydraulic medium via the rotary feedthrough 25 in the shaft section 11 on which the clutch 13 is stored, inserted, and transferred into the shaft section 11 as well as the hub 17 integrated holes 26 respectively. 27 in one of the axially displaceable coupling ring 16 limited pressure chamber 23 is introduced. In the coupling arrangement according to the invention 10 Accordingly, the actual coupling function and the actuation function for the clutch are combined. The axially movable coupling ring 16 assumes the function of a state of the art technology as a separate module trained pneumatic cylinder.
  • This makes it possible, the entire coupling assembly close to the wall 14 in which the printing press cylinder 12 over the camp 15 is stored, to position. A possibly occurring deflection of the printing press cylinder 12 or the shaft section 11 the same then remains for the clutch assembly according to the invention 10 or for the associated drive wheels 19 almost without influence, since the effect of the deflection is the lower, the closer the clutch assembly and thus the drive wheels on the wall 14 is positioned.
  • The inventive coupling arrangement is preferably used for transmission of drive power between two printing press cylinders or between a printing press cylinder or other aggregate a printing press. Equally important is the application of the optional mechanical coupling of two printing press cylinders, so that in If a clutch is closed, drive two drives together can and in the case of an open clutch, each press cylinder independently from the other press cylinder with its associated drive can be driven.
  • 2 shows two in a wall 14 a printing press mounted printing press cylinder 12 , each with a warehouse 15 in the wall 14 are rotatably mounted, the bearings 15 in contrast to the embodiment of 1 are designed as centric bearings. The lower press cylinder 12 is axially movable, wherein the coupling can perform this axial movement with, since all components thereof are directly or indirectly connected to the printing press cylinder. Both press cylinders 12 stands sideways next to the wall 14 again a wave section 11 before, being on the shaft section 11 of the lower press cylinder 12 a coupling arrangement according to the invention 10 with a clutch 13 is arranged. The shaft section 11 of in 2 shown below printing press cylinder 12 associated clutch assembly 10 corresponds to the in 1 illustrated coupling arrangement 10 so that like reference numerals are used to avoid unnecessary repetition for like assemblies. With regard to construction and mode of action of the coupling arrangement 10 can on the remarks too 1 to get expelled.
  • In 2 is that the lower press cylinder 12 associated drive wheel 19 with a top press cylinder 12 associated drive wheel 32 engaged, wherein the shaft portion 11 of the upper press cylinder 12 next to this drive wheel 32 another drive wheel 33 assigned. The upper press cylinder 12 therefore has two wheel planes, which are driven by the drive wheels 32 . 33 are formed, with both wheel planes 32 and 33 due to the compact design of the clutch assembly according to the invention 10 in the immediate vicinity of the wall 14 are positioned. As a result, an inclination of the shaft sections due to a deflection of the printing press cylinder or due of transverse forces acting on the drive wheels for the drive wheels within the defined wheel planes almost without influence.
  • In the embodiment of 2 the coupling between the two press cylinders takes place 12 or between the drive wheels 19 and 32 from the wall 14 seen in the so-called second wheel plane. The drive wheel 33 the first gear plane may be in engagement with another, not shown drive wheel of another printing press cylinder or other aggregate of the printing press. This drive wheel could for example also be a pulley. In the embodiment of 2 can, for example, at the bottom press cylinder 12 provided drive power by operating the clutch 13 in the upper press cylinder 12 be driven. It is also conceivable that on the upper press cylinder 12 of the 2 Drive power is provided, which then by operating the clutch 13 at the bottom press cylinder 12 is made available. It is also conceivable that on the drive wheel 19 driving power to the upper press cylinder 12 is supplied and only when required by closing the clutch and the lower press cylinder 12 is driven with. Alternatively, the lower press cylinder could 12 Also have a separate drive that drives with the clutch closed, with the clutch open the printing press cylinder 12 can drive independently.
  • 3 shows an arrangement comparable to 2 , where in 3 again two printing press cylinders 12 on top of each other in a wall 14 a printing press about bearings 15 are stored, and wherein in the arrangement of 3 the shaft section 11 of the upper press cylinder 12 a coupling arrangement according to the invention 10 with a clutch 13 assigned. The lower press cylinder 12 in turn are two drive wheels 34 and 35 assigned, the drive wheel 19 in the presentation of the 3 with the drive wheel positioned in the first gear plane 34 of the lower press cylinder 12 engaged. In the 3 the upper press cylinder 12 associated clutch assembly 10 again has a single clutch 13 and corresponds in construction and operation of the clutch assemblies 10 of the 1 and 2 , The coupling arrangement 10 of the 3 differs from the clutch arrangements 10 of the 1 and 2 only in that in the embodiment of the 3 the drive wheel 19 closer to the wall 14 moved and thus the coupling rings 16 and 20 not as in the embodiment of 1 and 2 between the wall 14 and the drive wheel 19 are positioned, but rather such side of the drive wheel 19 in that these two assemblies are positioned in the second gear plane, that of the drive wheel 35 of the lower press cylinder 12 is defined. Structure and operation of the clutch assembly 10 of the 3 However, in turn agree with the embodiments of the 1 and 2 match, so that reference is made here to avoid unnecessary repetition of the above statements.
  • In the arrangement of 4 Again, two are in a wall 14 a printing press rotatably mounted printing press cylinder 12 shown in the embodiment of the 4 the shaft sections 11 both press cylinders 12 in each case a coupling arrangement according to the invention 10 is assigned, each one a clutch 13 include. The two printing press cylinders 12 associated clutch assemblies 10 in terms of design and operation again in detail with reference to 1 described clutch assembly 10 , so that the same reference numbers are used here to avoid unnecessary repetitions for the same modules. In the embodiment of 4 stand the two drive wheels 19 engaged with each other. In the arrangement of 4 can in turn z. B. on one of the two printing press cylinders 12 provided drive power by operating the clutches 13 the clutch assemblies 10 in the other press cylinders 12 be driven. It is also conceivable that z. B. with one of the two drive wheels 19 a drive wheel of a non-illustrated, further printing press cylinder is engaged so as to the non-illustrated printing machine cylinder provided drive power by correspondingly actuating the two clutch assemblies 10 If necessary, in the two or in one of the two illustrated printing press cylinder 12 couple. Are the clutches 13 both coupling arrangements 10 opened, then stand the drive wheels 19 out of engagement with the axially displaceable coupling rings 16 , so that both drive wheels 19 compared to the illustrated printing machine cylinders 12 or the shaft sections 11 the same decoupled and thus can rotate freely.
  • Conceivable are again several drives, which in the case of closed clutches driving the press cylinders together and in the case open Clutches drive the respective press cylinder separately.
  • 5 and 6 show arrangements of three printing press cylinders 12 , wherein in each case the shaft section 11 of the middle press cylinder 12 a coupling arrangement according to the invention 10 from two clutches 13 assigned. The two clutches 13 the clutch assemblies 10 of the 5 and 6 correspond in structure and mode of action of the coupling 13 the clutch assembly 10 according to 1 , so that in turn to avoid unnecessary repetition for the same components same reference numerals are used.
  • The above and below the middle press cylinder 12 positioned printing press cylinder 12 wear on their shaft sections 11 Drive wheels positioned in different wheel planes 36 . 37 . 38 such as 39 , In the in 5 The arrangement shown are those of the upper printing press cylinder 12 associated drive wheels 36 and 37 arranged in the first and second wheel plane, whereas the lower press cylinder 12 associated drive wheels 38 and 39 are positioned in the first and third wheel plane. The drive wheels 19 the two the middle press cylinder 12 associated couplings 13 stand with the drive wheels 37 such as 39 engaged, so that in the arrangement of the 5 Coupling operations in the second and third wheel plane done. With the drive wheels positioned in the first gear plane 36 and 38 can Antriebrädern other unrepresented printing press cylinders or other units of the printing press are engaged.
  • In the arrangement of 6 on the other hand are the upper press cylinders 12 associated drive wheels 36 and 37 in the second and third wheel plane and the lower press cylinder 12 associated drive wheels 38 and 39 arranged in the first and second gear plane, allowing coupling operations between the drive wheels 19 the clutch assembly 10 and the drive wheels 37 and 38 of the upper press cylinder 12 as well as lower press cylinder 12 take place in the first and third wheel plane.
  • Also with the arrangements of the 5 and 6 it is again possible with open clutches only to drive the printing press cylinders, which are assigned to drive, or to drive the zugekuppelten press cylinders when the clutch is closed. Also conceivable here are several drives that drive together with the clutches closed and drive separately with open clutches. For example, drive two drives into the drive wheels 19 In this case, in the case of opened clutches, the middle press cylinder would be disconnected from the drive, during which the upper press cylinder and the lower press cylinder with their associated drives can be moved independently of each other. With the clutches closed, both drivetrains could jointly drive all three press cylinders, as well as possibly other press cylinders, which are mechanically connected to them.
  • As 5 and 6 can be taken in the shaft section 11 of the middle press cylinder 12 which the clutch assembly 10 with the two clutches 13 carries, two holes 26 integrated, over which in connections with those in the hubs 17 integrated holes 27 the pneumatic medium in the pressure chambers 23 the two clutches 13 can be directed. Then, if on a shaft section 11 several couplings 13 are positioned axially adjacent to each other, are in the shaft section 11 therefore several holes 26 integrated to the operation of the respective couplings 13 required pneumatic medium or hydraulic medium in the direction of the respective axially displaceable coupling rings 16 the couplings 13 to lead. Dement speaking are also the rotary joints 25 two connections 29 assigned to each of the two clutches 13 the clutch assemblies 10 the embodiments according to 5 and 6 to operate independently of each other.
  • In the 1 to 6 Coupling arrangements shown with the clutches have a very compact design, which ultimately makes it possible to provide very close to the wall a plurality of wheel planes and thus drive levels over which press cylinders can be coupled with each other or with other aggregates of a printing press. It is possible to arrange the drive wheels in two, three or even more wheel planes such that the spacing of the drive wheels is in each case relatively close to the wall in which the printing press cylinder is mounted. All drive wheels of a clutch assembly can be actuated independently by correspondingly actuating the axially displaceable clutch rings. Even if z. B. three gear planes and thus drive levels are positioned side by side, the distance between the wall and the corresponding drive wheels in an area that is small enough that any deflections of the printing press cylinder and thus the shaft sections on which the clutches are positioned on the operation the clutches and on the engagement of the associated drive wheels have no effect. If the drive wheels are toothed wheels, a parallel position of the tooth flanks of adjacent toothed wheels is ensured on account of the low propriety to the wall. If the drive wheels are pulleys, it is ensured that the inclination of the shaft sections is relatively small, since the biasing force of the belt due to the short design of the clutch acts close to the wall.
