摘要:
A printed matter transport device. Printed matter is gripped by a gripping mechanism of a chain and made to travel along a guide rail, to improve the durability of the guide rail and chain, to prevent misalignment, falling out and damage when an external force acts on the printed matter, to improve durability of a connecting part of a chain link and the gripping mechanism, to reduce manufacturing costs, and to enable the printed matter to be firmly gripped. A chain with grips having first rollers respectively arranged on two sides in the center of the longitudinal direction of the bases, a second roller on one side perpendicular to the common center line of the first rollers and a grip mechanism on the opposite side, a guide rail, a chain drive and a cam member are provided.

Arrangements are described which allow a printing stock web to be reliably drawn through a drier. A draw-in member which grasps the tip of a printing stock web has a power transmission, e.g. a roller chain, which runs in a guide. Plates or blowing boxes which are movable vertically to the draw-in plane of the printing stock web and form closures in the guide by lateral projections of their side walls are provided to prevent dirt from penetrating into this guide. Rollers or cylinders are provided for additional correction of a lateral displacement of the printing stock web while the web is drawn in by the draw-in member. A friction-locking engagement, i.e., particularly rolling friction or adhesive friction, causes these rollers or cylinders either to exert a transverse traction on the printing stock web themselves or, in order to compensate for the lateral displacement of the printing stock web, secure the printing stock web in the correct position due to a transverse traction produced by an oppositely directed displacement of the guide.

A device for conveying and transferring flexible, flat objects with a gripper conveyor including a plurality of grippers that are movable along a conveying path in a conveying direction, and further with a conveying-way device that forms a conveying rest that, in a transfer region, is arranged below the conveying path such that objects that are released from grippers in the transfer region are deposited onto the conveying rest. The device includes a pressing circulatory device that acts upon the transfer region and has a plurality of outwardly directed pressing arms. The pressing circulatory device is designed, in the transfer region, to press the objects to be transferred with the pressing arms onto the conveying rest such that the objects can be deposited onto the conveying rest in a guided and controlled manner.

The invention relates to a conveying unit for guiding and conveying a material web in a thermoform packaging machine, comprising, on either longitudinal side of a machine frame, a conveyor chain, a chain wheel and a guide device. A chain link of the conveyor chain and a clamp guide can be implemented together and in one piece as a shaped part.
摘要:
A device and method for the transfer flexible flat articles between two conveyors. The device includes a first gripper conveyor with first grippers moved along a first gripper conveyor track for suspended transportation of the articles in a conveying direction, and a second gripper conveyor with second grippers moved along a second gripper conveyor track. Opening and closing of the grippers is controlled so that a transfer of the articles from the first to the second grippers is able to take place. In doing so, a spacing between the first grippers differs from the spacing between the second grippers such that, in a transfer zone, one gripper conveyor track, the grippers of which include the greater spacing between one another, defines a concave course, and the other gripper conveyor track, the grippers of which have the smaller spacing between one another, defines a correspondingly convex course.

A clamping element for attaching a gripper onto a clamping tongue as well as a gripper with this kind of clamping element is provided. The clamping element has a longitudinal carrier the width of which substantially corresponds to the width of the clamping tongue and at least two mutually distanced clamping regions. At least one fastening element for the detachable fastening of the clamping elements to the clamping tongue (42, 44) is provided. The clamping element provides an improved force division as well as a secure support on the clamping tongue.

A medium conveying device includes a first guide member, a second guide member, a conveying member, and a support member. The first guide member guides one face of a medium to be conveyed and opposed to the one face when the medium is conveyed. The second guide member guides the other face of the medium and is opposed to the other face when the medium is conveyed, the second guide member being movable between a close position and an open position. The conveying member is provided in a conveying passage formed by the first guide member and the second guide member being at the close position in order to convey the medium in the conveying passage. The support member keeps the second guide member at the open position and is provided at a position outer than the second guide member in a direction that the medium is conveyed. When the second guide member is at the open position, the medium in the conveying passage is removable from the conveying passage.

Disclosed is a transfer device (5) for substrates used for producing electronic components or displays. Said transfer device (5) is used for delivering substrates to a process station (4) and comprises a first feeding/discharge interface (7) to an overhead conveying system (1) for substrate transport boxes (2) as well as a second feeding/discharge interface (26) to the process station (4). The first interface (7) is located above the second interface (26) relative to a vertical direction. In order to provide such a transfer device (5) with greater flexibility in terms of the order in which the conveyed substrates are delivered to process stations (4) in an interlinked production plant for conveying substrates in transport boxes (2), said transfer device (5) comprises means (24, 25, 27) which allow the substrates to be conveyed from one interface (7) to the other (26) free from transport boxes (2) with the help of a handling mechanism (12) that is arranged within the transfer device (5).

A feeder for collecting printed sheets in an astride position includes a pulling-off drum which has at the circumference thereof gripping members for pulling off printed sheets stacked in a magazine. The feeder further includes a unit for conveying the printed sheets with an open side facing forward into an opening device. The opening device is arranged in front of a collecting device. The unit arranged between the pulling-off drum and the opening device is formed by a pocket wheel or a pocket chain provided with revolving pockets for receiving the printed sheets which are supplied with their folds facing forwardly, and a conveying member arranged in front of the pockets.
摘要:
Printed products (10) are conveyed to a transfer portion (22) by means of the grippers (14) of the gripper conveyor (12). The vacuum belt conveyor (26) suctions with its active strand (28) the respective end region (32) of the printed products (10), after which, close to the end of the (34) of the transfer portion (22), the grippers (14) respectively release the printed products (10). The motional path (38) of the gripper jaws (16) runs in the transfer portion (22) in the shape of an arc. The active strand (28) of the vacuum belt conveyor (26) runs in the transfer portion (22) at an approximately constant distance to the motional path (38). In the case of large processing capacities and correspondingly high velocities, a reliably secure, positionally stable transfer of the printed products (10) from the gripper conveyor (12) to the vacuum belt conveyor (26) is thereby ensured.
