Abstract: An envelope-filling bench for adding onto a push-in station of mail-processing machine, the bench containing an envelope-conveyor for transporting envelopes in front of the push-in station and for transporting them away once the envelopes have been filled with enclosures or sets of enclosures. The envelope-filling bench formed essentially from two vertical transverse partition walls, which are spaced apart parallel to one another, a sheet-metal C-profile support, which runs horizontally the direction perpendicular to the transverse partition walls, and a sheet-metal L-profile support, which is welded into said sheet-metal profile support. It being the case that openings and cutouts in the walls of box chamber enclosed by the sheet-metal supports are produced by punching sheet-metal blanks prior to the production of the sheet-metal supports by angling operations.

Abstract: In an apparatus for handling sheet-like articles, in particular in an envelope-filling station, in which a carrier (9) provided with push-in fingers (11) is moved back and forth by means of an actuating arrangement (12, 13, 14, 15, 16, 21, 26, 27, 28, 29, 31, 32) in order for articles which are conveyed up by means of a conveying path (2) to be received from the conveying path and handled in the conveying direction, improved adaptation of the handling speed of the push-in fingers (11) to the conveying speed of the conveying path (2) is achieved in that a drive mechanism (21, 26, 27, 28, 29, 31, 32) of the actuating arrangement contains a crank drive, on the crankshaft (28) of which there is fastened an elliptical two-belt pulley (29) which is coupled, via a toothed belt (31) to a continuously driven, round belt pulley (32).

Abstract: The invention proposes an envelope-filling bench for adding onto a push-in station of a mail-processing machine, the bench containing envelope-conveying means for transporting envelopes in front of the push-in station and for transporting them away once the envelopes have been filled with enclosures or sets of enclosures. The envelope-filling bench is formed essentially from two vertical transverse partition walls, which are spaced apart parallel to one another, a sheet-metal C-profile support, which runs horizontally in the direction perpendicular to the transverse partition walls, and a sheet-metal L-profile support, which is welded into said sheet-metal C-profile support, it being the case that openings and cutouts in the walls of a box chamber enclosed by the sheet-metal supports are produced by punching sheet-metal blanks prior to the production of the sheet-metal supports by angling operations.

Abstract: A drive and actuating system for an envelope-filling station in which enclosures or sets of enclosures are fed, by a driven conveyor, to a push-in station in which a push-in arrangement, which has a pivot drive, receives the enclosures or sets of enclosures and pushes them into envelopes, which are held ready in an open state. The envelopes are then delivered into a position opposite the push-in station, from oriented transversely to the push-in direction, by an envelope-conveying arrangement. Further, a multiplicity of functions of the individual parts of the envelope-filling station can be forcibly synchronized in an adjustable manner and a comparatively straightforward and clear construction of the overall drive and actuating system is produced.

Abstract: In an envelope-filling apparatus for mail-processing machines, the adjustment of the push-in depth of enclosures into open envelopes in the operating stroke of a pivot-lever arrangement, which bears a push-in-finger arrangement, is simplified in that said pivot-lever arrangement is designed as a three-lever rectilinear-guidance mechanism, of which the third lever, which serves as the carrier hand for the push-in-finger arrangement, has, at its free end, a slide guide which can be secured and is intended for adjusting the distance between a push-in-finger shaft for the push-in-finger arrangement and the point of articulation of the longer lever of the three-lever rectilinear-guidance means on the carrier hand.

Abstract: In an apparatus for handling sheet-like articles, in particular in an envelope-filling station, the smoothness of running is increased, even in the case of high cycle speeds, in that a guide control means is provided so that push-in fingers, which are moved back and forth by an actuating arrangement, can be lowered and raised relative to a base plate both in the operating stroke and in the return stroke, it being the case that provided for the operating stroke is a framework-side guide part and for the return stroke is a diverter-like changeover guide part, which is actuated by the guide contact element itself and ensures in each case smooth transitions to the housing-side guide part.

Abstract: A charging apparatus for handling stations for sheet-like, flexible articles, in particular envelopes, particularly for mail-processing machines, the drive in a feed-channel for stacks of articles standing on edge being controlled in dependence on a detector output signal produced by a light barrier, which responds to the formation of a gap and runs transversely to the conveying direction with the gap forming in the region of a transition between the feed channel and a discharge channel.

The envelopes are conveyed by an envelope-conveying arrangement, on the envelope-filling bench, into a position opposite the push-in arrangement and being opened there and held ready for receiving the enclosures or sets of enclosures.

Abstract: In a gripper mechanism for devices for handling sheet-like or plate-like articles, particularly for mail-processing machines, simple and reliable setting for the handling of light, thin and also heavy, thick articles can be effected by the use of pivotable gripper claws on the gripper hand provided at the end of a pivotable gripper arm, by virtue of the fact that a plane which is oriented approximately perpendicular to the gripper arm longitudinal axis, and in which the contact area between articles to be handled and a pivotable gripper claw also lies, is at such a distance in the direction of the longitudinal axis of the gripper arm from the pivot axis of this pivotable gripper claw that an additional pivoting moment acts on the latter in the closure direction, generated under the effect of tensile forces which seek to remove the articles to be handled from the gripper claws when these are closed, as a result of which articles of widely varying weight and varying thickness are at all times gripped securely.

Abstract: In the case of a charging apparatus for handling stations for sheet-like, flexible articles, in particular envelopes, particularly for mail-processing machines, the drive in a feed channel for stacks of articles standing on edge is controlled in dependence on a detector output signal produced by means of a light barrier, which responds to the formation of a gap, running transversely to the conveying direction, in the stack of conveyed articles, said gap forming in the region of a transition, formed as a rib or sill, of the feed channel to an obliquely upwardly running discharge channel for the articles which are to be handled.

Abstract: With regard to an installation designed to handle sheet-like pieces by means of gripper arms (1) provided with gripper clutches (9, 10), a particularly simple and economical structure requiring less components can be obtained by a design according to which the distribution crankshaft gear carries a distributing disk with operating cams (18, 11a, 18a, 113) for enabling oscillatory movements by the gripper arm (1), said disk interacting with the cam follower (17) in an actuating mechanism which is coupled with the swivelling gripper clutch (10) of the clamping device (3) and mounted on the gripper arm (1). The distributing disk has been specially designed for that purpose.

Abstract: In a gripper mechanism for devices for handling objects in the form of sheets or plates, simple and easy operability of the gripper claws of pivoting gripper arms into the open position for adjustment purposes, test purposes and the like is achieved in that a manual operating element made of plastic is connected in the gripper claw operating drive between an operating lever which is mounted on the relevant gripper arm such that it can pivot, and a coupling linkage which is connected to one of the gripper claws which can pivot, and this manual operating element can pivot on the operating shaft of the gripper claw operating drive in such a manner that the claw can be caused to open easily while the machine is at rest, without any risk of injuries.

Abstract: A feeding machine for feeding envelopes into a station for further individual handling. A stack of envelopes is held in a downwardly inclined feed channel. The stack of envelopes is transformed into a layered stream by an upward inclined discharge channel including a conveyor unit that carries a stream of envelopes through a gap formed by an imbricator strip and a low friction circulation belt. The layered stream is conveyed to a removal point where a removal device removes individual envelopes for further processing. The conveyance of the layered stream is controlled in such a manner that the removal device can remove individual envelopes at regular time intervals.

Abstract: The invention proposes a handling apparatus for moving sheet-like articles, in particular an inserter for pushing inserts into envelopes, in which apparatus a link hand, which forms part of a rectilinear-guidance mechanism formed from three links, has spring-loaded fingers which are articulated at the free end of the link hand and slide over a base plate during the operating stroke, while, during a return stroke, the fingers are raised off together from the base plate by means of a control guide arrangement. Said apparatus operates at high cycle speeds without disruption and requires the arrangement as a whole to be of just a small overall height.

Abstract: In a drive system for a mail processing machine a comparatively simple and clear design of the driving tracks and of the bearings for the respective shafts is obtained by feeding drive energy from a common drive motor to a bevel gear drive and a step gear drive. Thereby, the output shafts of the bevel gear drive and the step gear drive have identical sense of rotation because of the sense of rotation reversal within the respective gear drive. The bevel gear drive, at its output, provides a continuous rotation, and the step gear drive provides an intermittent rotation. From the output shafts of the bevel gear drive and of the step gear drive, respectively, driving connections can be led to the driving shafts for a continuously moved conveyor chain for documents and to an intermittently moved conveyor chain for documents, respectively.
