摘要:
A supply station for positioning enclosures on an enclosure-collating path of a mail-processing installation allows a simple conversion from operation for processing a stack of comparatively flexible, thin enclosures to operation for processing a stack of comparatively thick, essentially inflexible enclosures. The conversion is achieved using a magazine housing inside a supply station housing mounted so that it can be secured in two different pivot positions, whereby in one pivot position the lowermost enclosure of a stack of enclosures is bent using a vacuum arrangement in which the front end of the enclosure in the withdrawal direction can be gripped by a gripper, while in a second pivot position of the magazine housing, the front end in the withdrawal direction of a lowermost, comparatively thick and essentially inflexible enclosure is pushed by means of a pusher arrangement directly into the open claws of the gripper.

In an envelope-filling station for mail processing systems having an envelope-feeding arrangement for single, open envelopes, an intermediate envelope-conveying arrangement extending at an angle thereto in the direction of an angle stop arrangement provided for the purpose of aligning the envelope, and an envelope-advancing arrangement from which the envelopes are accepted from the angle stop arrangement, a simplification of the design, and effort needed to control the component parts is achieved when the angle stop arrangement, with the exception of a stopping straightedge that is to be provided to achieve extremely precise alignment of an envelope that is supplied at an angle, contains as a further part of the angle stop arrangement a conveying nip between the upper strand of an intermittently driven conveying belt of the envelope-advancing arrangement and a pressure-exerting roller that is pre-tensioned near the beginning of the upper strand of this conveying belt. The envelope-advancing arrangement has coupling means following the pressure-exerting roller that interact with the intermittently driven upper strand of the conveying belt of this envelope-advancing arrangement, in particular a roller bar that can be moved up and down, said means conveying an aligned envelope to a position in front of the feeding station, independent of the function of the pressure-exerting roller, and transporting the filled envelope out of the inserting station.

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.

In the case of a mail-processing machine having a conveying path (1) which contains a circulating conveying chain and conveys onto a handling station (5), easy changeover to a variety of processing tasks and good adaptability to constricted space conditions are achieved in that, by a switchable actuating arrangement, manipulator fingers (19) articulated on a manipulator hand (13), in the handling station (5), can be switched both into the operating position both for the forward stroke of the manipulator hand and for the return stroke of the manipulator hand and into the return position both for the return stroke of the manipulator hand and for the forward stroke of the manipulator hand. Free through-passage-channel areas (32, 33) for sheet like article and sets thereof which are to be processed further or are to be inserted into envelopes are provided in the handling station, not only with regard to the direction (F) from the feeding conveying chain and to a laterally adjacent first processing arrangement but also in the opposite direction perpendicular to the feed direction of the first conveying chain.

In a rotary feeder for conveying enclosures, in particular into conveying compartments of an enclosure-collating path, during operation, shocks within the gear mechanism of the drive unit of the feeder drum on account of gear mechanism play are avoided and the level of noise during operation is reduced in that a cam-actuated pair of claws (10, 11) is provided in each case at two diametrically opposite locations of the feeder drum (2) of the rotary feeder, and the cam (16) for actuating the pairs of claws is configured in sections (O) with an increasing in the radial spacing of its profile in accordance with a claw-opening movement counter to the prestressing force of prestressing means (19, 20) and, in sections (C) with a decrease in the radial spacing of its profile in accordance with a claw-closing movement under the prestressing force of the prestressing means, such that a braking moment on account of the claw opening counter to the prestressing force of the prestressing means, this braking moment being transmitted to a rotating follower roller (15) and a link (14), bearing the latter, for claw actuation, and to the feeder drum (2) via the claw pivoting shaft (9), is compensated for by an accelerating moment on account of the claw closure under the prestressing force of the prestressing means, this accelerating moment being transmitted to a rotating follower roller (15) and a link (14), bearing the latter, for claw actuation, and to the feeder drum (2).
摘要:
Disclosed is an inserter station for mail processing systems, consisting of a feeder device (2) for transporting inserts, an envelope separation device for separating envelopes from a stack of envelopes, also comprising a mail transport device (6) which is located parallel to the transport track of the feeder device extending close thereto in order to take up the individual envelopes, further comprising orienting means (30,32) for positioning an envelope to be filled in a precise position in front of an insertion device (35). According to the invention, the complex action of orienting the envelopes to be filled on the path between the envelope separation device (7) and the insertion device (35) is simplified by configuring the envelope transport device (6) at least in one end section adjacent to the intermediate envelope transport device (16) such that the envelope can be horizontally displaced with the aid of a displacement component perpendicular to the direction of transport of the intermediate envelope transport device (16). The intermediate envelope transport device (16) has a direction of transport extending at an angle (alpha) in relation to the direction of transport of the envelope transport device and can extract a transported envelope in an oblique position with respect to the horizontal direction and transport it against an angle stop device (30,32) which can be switched either actively or inactively at random and which in an active position produces a precise orientation of the envelope to be filled with inserts or series of inserts.
