摘要:
A conveying device includes a mount frame, a first guide mounted on the mount frame along a conveying circuit, several transport trolleys distributed along the conveying circuit, and a system for driving each of the transport trolleys comprising a second guide mounted on each of said transport trolleys and designed to co-operate with the first guide, a transmission connected to the transport trolleys. Advantageously, each of the transport trolleys includes a support having at least one useful face, advantageously intended for supporting at least a dish, and maintained in a substantially horizontal position. The invention is useful for fast catering service in a restaurant hall or the like.

A self-clearing article-transfer plate for a conveyor system. The plate is disposed between an upstream article feeder, such as a conveyor belt supplying a stream of conveyed articles, and a downstream article receiver, such as a takeaway belt or an accumulation table. The plate may have a tapered edge or a fingered edge at a first end for receiving articles from the article feeder. Backpressure from the stream of articles pushes the articles onto, across, and off a second opposite end of the plate onto the article receiver. When the stream of articles stops or is interrupted, the last articles in the stream are urged along the plate from the first end to the second end by vibrations from a vibrator affixed to a support for the plate. In this way, articles are cleared from the plate, without being stranded, even in the absence of backpressure.

A unit for transferring groups of cigarettes has a conveyor having pockets for housing the groups and for feeding the groups in a first direction; a guide for guiding each group into a respective pocket along a path in a second direction crosswise to the first direction; and a safety device having a guide member adjacent to the conveyor and movable between a work position defining part of the path, and an emergency position remote from the path; the unit also having a spring for setting the guide member to the emergency position when a group of cigarettes transmits to the guide member a force over and above a given threshold value.

The present invention relates to a linear stage with a seal band, including a dustproof belt, wherein the dustproof belt is made of high-molecular material, so that the loss value of the power of the movement seat of the linear stage may be reduced. In addition, the roller set is designed as the guide device, so that the contact resistance may be reduced, thereby increasing the working efficiency and the exactness of the linear stage.

The invention relates to a process for continuous treatment of objects in a processing unit, where the objects are moved along a conveyor track passing through the processing unit by a first linear-action conveyor device performing a back-and-forward movement and where the objects are supplied to/removed from the conveyor track by a transfer device. To permit with measures of simple design a continuous treatment without parasitic depositions or high temperatures impairing the process sequence, it is proposed that the objects be arranged on supports which are lined up on the conveyor track by at least two first linear-action conveying devices performing a back-and-forward movement and are then conveyed continuously through the processing unit, where the lining up and subsequent continuous conveying of the supports is performed such that one of the first conveying devices lines up a support transferred to the conveyor track with those supports already on the conveyor track while the other first conveying device continuously conveys the previously lined-up supports.

The transport device serves to horizontally convey workpieces and has a plurality of plate elements, which are plug connected onto a vertically aligned tooth belt and are guided by it along an endless path. Each plate element is separately connected to the tooth belt and separately replaceable. The transport device ensures extremely precise positioning of the plate elements at the processing stations for the workpieces in a simple manner.

Workpieces in the shape of plates can be transported from an input station to a workstation and from there to an output station by means of two manipulation device in a working plane. A gripper of one of the manipulation means can be displaced between the input station and the workstation. The gripper of the other manipulation device can be displaced between the workstation and the output station, whereby the displacement ranges overlap. As the first half of the processing time has been approximately completed in the workstation, the workpiece r is transferred from the gripper on the input side to the gripper on the output side. Meanwhile, the respectively free gripper returns to its station and to the workstation, so that the processing can be carried out almost without any interruption.

The present invention provides an automatic device for discharging, from a vibrating table to an on-line conveyor, continuously arriving flat-bottomed objects, which device operates in cycles and each of the cycles of which includes the following stages: said objects are accommodated in a ditch contiguous with the forward edge of said vibrating table (1) so as to form a row; said row of objects is pushed by a pusher (11), the initial speed of which is zero, towards a smooth surface (12) extending in a transverse direction in relation to the vibrating table (1) in the continuation of the ditch (4); said objects arrive on a conveyor belt (13) located in the continuation of the smooth surface (12); and, while the pusher (11) discharges said row and then returns to its initial position, a fresh row of objects gradually forms in the ditch (4).

In an apparatus for automatically transporting workpieces in a multi-stage forming machine, a tong casing (1) is fitted on a transverse transporting tube (2). The tong casing (1) comprises a tong-casing basic body (10) on which there are arranged exchangeable tong modules (12a, 12b, 12c) each with one set of tongs by means of which a workpiece (W2, W3) can be seized laterally from above. Each set of tongs is connected, via a coupling location (19), to associated transmission means which, are in operative connection with a control shaft (3), mounted rotatably in the transverse transporting tube (2), for controlling the opening and closing movements of the tongs. The operation of transporting, from one forming station (U1, U2, U3) to the adjacent forming station (U2, U3, U4), a workpiece (W2, W3) seized by tongs with pairs of interacting tong grippers (130, 140) and the operation of moving the tongs back take place by the transverse transporting tube (2) moving back and forth. The tong displacement can be adapted to the workpieces (W2, W3) by using tong modules (12a, 12b, 12c) with tongs with suitable leverages.
