Definitions

the invention relates to a sheet delivery for a sheet-fed printing press, in which fold-away stacking stops and catch fingers that can be inserted briefly are provided according to the preamble of claim 1.
Such a sheet delivery device is known from DE-PS 23 01 840.
the design features of this known arrangement make it possible, on the one hand, to remove a sample sheet and, on the other hand, to insert an auxiliary stacking device, for example a stacking rake or the like, in order to use the sheet stack in the sheet delivery device in non-stop operation to be able to switch.
the sheets are transported from the sheet printing machine by endless chain conveyors with the leading edge of the sheet against the stacking stops arranged in a collapsible manner and placed on the sheet stack.
the catch fingers which can be inserted briefly from the front edge of the sheet up to the sheet stack and are arranged on one arm of an angle lever, the other arm of which is connected to a swivel arm via a resilient connecting member, are used to remove sample sheets and to form an auxiliary stack in non-stop operation is, which sits on the pivotable by means of a hand lever pivot shaft for the stacking stops, so that the movement of the catch fingers and the stacking stops can take place in the required dependence on each other.
a parallel guide linkage converts the rotary movement of the swivel shaft into an insertion movement, in which the catch fingers maintain their horizontal position, but move on an arc path, which impairs operational safety. With the catch fingers pushed in and, in contrast, folded away with a delay Stack stops can either be taken from a sample sheet or an auxiliary device can be inserted to form an auxiliary stack for the stack change in non-stop operation.
the movement of the catch fingers is motorized by means of a pneumatic cylinder, the movement of which, however, is controlled by the hand lever operating the pivot shaft for the stack stops via a switching element, in order in this way to relate the interdependency of the movements of the stack stops and the catch fingers to reach.
a sheet delivery with a catching device for the leading edge of the sheet is known, in which the catching fingers can be pivoted about angular gears about horizontal axes, so that a lever guide for securing the most straight-line catching finger movement parallel to the plane of the incoming sheet is omitted , but in this device, which can also be operated by means of a hand lever, the folding movement of the stacking stops begins at the same time as the swiveling movement of the catch fingers, so that there is a considerable risk of slipping of sheets when switching over, especially in high-speed machines.
the invention has for its object to develop a sheet delivery of the type mentioned in such a way that with further improvement in operational reliability when taking a sample sheet or when changing stacks more precise movements with higher speeds of movement can be achieved and a movement of the catch fingers and the stack stops each independently motor drives is possible.
motor drives separately for the stack stops and for the movement of the catch fingers enables the use of simple switching elements for the inevitably dependent control of the movements from one another and for the individual control of both movement processes. Above all, this also makes it possible that the motor drives can be arranged on one of the two machine sides of the boom, on the outside of the machine frame, which means that they can be accommodated in the interior of the bow arm, which is very narrow in modern machines, between the side walls of the frame not applicable.
the motor drives each act directly on a shaft, the angular movement of which is translated by means of transmission elements to the desired extent and is converted into a linear thrust movement in the case of the catching fingers, so that the catching fingers can be guided exactly parallel to the plane of the sheets in the sheet stack during their movement.
1 and 2 show the two side walls of the frame of the sheet delivery of a sheet printing machine.
the sheets arriving from the sheet printing machine are transported up to a sheet stack 3 and placed on this sheet stack.
the incoming sheets are transported with the leading edge of the sheet up to stacking stops 4, of which several are arranged next to one another.
the stacking stops 4 are fastened to a swivel shaft 5 arranged transversely, which is rotatably mounted in the side walls 1 and 2 of the frame, so that the stacking stops 4 can be folded away by a rotary movement of the swivel shaft 5 and folded back on again.
the pivot shaft 5 is guided on one machine side to the outside of the side wall 2.
the end of the pivot shaft 5 is connected by transmission members 6 to a drive shaft 7, the motor drive of which consists of a pneumatic cylinder 8, and which has an eccentric connection with respect to the shaft axis.
a drive shaft 7 the motor drive of which consists of a pneumatic cylinder 8, and which has an eccentric connection with respect to the shaft axis.
an eccentrically arranged rod head 9 is also effective, by means of which an intermittent abrupt movement is transmitted to the stacking stops 4.
the pneumatic cylinder 8 acting on both sides enables the stacking stops 4 to be folded away and these stacking stops to be folded back.
catch fingers 10 are fastened to a support 11 which extends across the stack width and is guided on guides aligned parallel to the sheet plane in the sheet stack 3 12 is guided back and forth so that the catch fingers 10 perform a precisely defined linear movement during their movement.
the catch fingers are also driven by a drive shaft 13 which is articulated to the support 11 by articulated lever 14 and is mounted coaxially to the drive shaft 7 for the stacking stops.
the coaxial mounting is made possible in that one end of the drive shaft 13, directly adjacent to the one side wall 2 of the frame, is rotatably mounted in a bearing 15 formed on the end face of the drive shaft 7, while the other end of the drive shaft 13 has a bearing 16 has in the opposite side wall 1.
the end of the drive shaft 13 led out of this side wall 1 is connected on this machine side by means of transmission elements 17 to a pneumatic cylinder 18 for the motor drive of the drive shaft 13.
the transmission member 17 is designed as a double lever, one arm of which is articulated to the pneumatic cylinder and the other arm of which is articulated to the articulated lever 14.
Each of the two pneumatic cylinders 8 and 18 can be actuated for example via switches 20 and 21 on a switch panel 19.
Both pneumatic cylinders 8 and 18 can also be mutually dependent on one another via a switch 22 are actuated so that the catch fingers 10 are first inserted over the stack before the stack stops 4 are folded away, in order then to remove one or more test sheets from the stack 3.
the individual actuation of the pneumatic cylinders 8 and 18 enables the catch fingers 10 to be inserted first, for example when changing stacks in non-stop operation, and then the auxiliary stacking device, for example a rake, an auxiliary stacking table or the like, is introduced before the Stacking stops 4 can be folded away for changing the stack 3. Conversely, the stacking stops 4 can then be folded back again before the auxiliary stack is released and the catch fingers are withdrawn.
