Patent number: 5722655Abstract: Sheet-like products are fed to the transfer location by a first conveyor. A detector arrangement determines the spacing between the products and controls the first predetermined speed of a second conveyor correspondingly, with the result that, at the transfer location, the formation of the products have a predefined spacing. If the second conveyor is driven, at the stationary transfer location, at the first predetermined speed which differs from a second predetermined speed at the stationary discharge location, the conveying length of the second conveyor changes, thereby displacing a deflection wheel. Different spacings between fed products can thus be evened out.Type: GrantFiled: May 8, 1997Date of Patent: March 3, 1998Assignee: Ferag AGInventor: Walter Reist

Patent number: 5364090Abstract: A sequence stacker edge stacks envelopes or the like. Belts carry shingled envelopes in a downstream direction to an angled stop. The belts are carefully spaced vertically above a deck. As a stack of envelopes forms against the stop, the weight of the stack deflects the belts until the top surfaces of the belts become aligned with a stationary surface. At that point, the weight of the stack is transferred from the belts to the stationary surface. Consequently, the downstream driving force of the belts on the envelopes' bottom edges is greatly reduced. The result is that the sequence stacker can stack many more envelopes without backward tipping of the envelopes than prior stacking machines. In an alternate design, certain portions of a stack remain urged downstream at all times by the belts. For that purpose, short spacers are placed at intervals under the belts.Type: GrantFiled: July 22, 1993Date of Patent: November 15, 1994Assignee: Tab Products CompanyInventors: Jeffrey C. Hollis, Chad Bones, Troy M. York

The ejecting wheels can be swiveled out of a position in which they are turned by half a tooth pitch with respect to each other into a position in which the stops of the two ejecting wheels are mutually aligned. If the ejecting wheels are offset with respect to each other by half a tooth pitch, each printing product inserted into a pocket of the paddle wheel runs onto a stop and is ejected by the latter from the pocket due to the different speeds of the paddle wheel and of the ejecting wheels and is deposited in imbricated formation onto the delivery conveyor. If, on the other hand, the stops of the two ejecting wheels are mutually aligned, the printing products of two successively occupied pockets in each case make contact with a stop, as a result of which the two printing products are ejected from the pockets mutually aligned with their fold.Type: GrantFiled: July 9, 1990Date of Patent: June 30, 1992Assignee: Ferag AGInventor: Jurg Eberle

Patent number: 5116043Abstract: A stream of square folded sheets, wherein one marginal portion is thicker than the marginal portion which is parallel thereto, is fed into the nip of a rotary core and one or more flexible bands which are being convoluted onto the core whereby the sheets form a roll having convolutions which alternate with the convolutions of the band or bands. The thicker marginal portions of the sheets are fed in a direction at right angles to the axis of rotation of the core so that, in the absence of any undertaking to the contrary, the diameter of the respective end face of the roll would exceed the diameter of the other end face which is formed by the thinner marginal portions of the sheets. The development of such frustoconical roll is prevented by moving the single band or one of several bands close to that end face of the roll which is formed by the thicker marginal portions of the sheets and by maintaining the thus positioned band under requisite tension in order to compress the thicker marginal portions.Type: GrantFiled: May 23, 1991Date of Patent: May 26, 1992Assignee: Grapha-Holding AGInventors: Daniel Jermann, Bruno Muller

Patent number: 5088711Abstract: Magazine signatures which are manually loaded as a stack into a product hopper are stripped therefrom and are conveyed as a rough and non-uniform shingle to an accumulating hopper while being elevated from a low level to a substantially higher level. The signatures are stripped from the accumulating hopper and are formed into a thin and uniform running shingle with a comparatively large setback for transport along a horizontal path to a receiver hopper which is located at a relatively high elevation to feed the collating conveyor of a binding machine. The shingles are fed on an on-demand basis both to the accumulating hopper and to the receiver hopper in order to keep stacks of consistently low height and weight in the hoppers and thereby promote consistent stripping of shingle signatures from the hoppers.Type: GrantFiled: August 27, 1990Date of Patent: February 18, 1992Inventor: John R. Newsome

Patent number: 5078260Abstract: A device for transferring continuously arriving articles, especially folded-bottom boxes lying with their ends that face each other along the direction of travel differing in thickness, to a packing machine, with a mechanism for distributing the articles onto two different conveyor mechanisms, one conveying the articles without rotating them to the upstream side of a merging mechanism and the other extending below the merging mechanism, through a 180.degree. curve, and back to its downstream side and a mechanism for alternately laying off flat articles, especially folded-bottom boxes, from each side of and onto a more or less horizontal merging mechanism that is especially intended for use with a device of the aforesaid type and that has two two-belt conveyor mechanisms that end at approximately the same level on each side of and outside the layoff area. The merging mechanism is a conveyor belt that branches off at an angle from the two conveyor mechanisms and extends to a packing machine.Type: GrantFiled: January 25, 1991Date of Patent: January 7, 1992Assignee: Jagenberg AktiengesellschaftInventors: Wolfgang Bensberg, Hans Bomer, Hartmut Klapp

Patent number: 5074541Abstract: A device for distributing finished photographic paper of the type in which finished photographic paper sheets discharged from a photographic-paper processing apparatus are transferred to a conveying belt by means of flappers, and are distributed and arranged on the conveying belt. The flappers are controlled in such a manner that they operate to transfer the finished photographic paper sheets selectively in conformance with the size of said photographic paper which are transferred to the conveying belt when a predetermined number of them have been accumulated on the flappers. And the distance of moving of the conveying belt is controlled when transferred to the conveying belt are arranged selectively in two modes, in one of which the piles of accumulated finished photographic paper sheets on the conveying belt is allowed to have an appropriate space between them, and in the other of which the piles partly overlap each other.Type: GrantFiled: September 1, 1989Date of Patent: December 24, 1991Assignee: Fuji Photo Film Co., Ltd.Inventor: Ken Kawada

Patent number: 5042792Abstract: A conveying apparatus delivers a succession of printing products in a first imbricated formation to a take-over region where the products are transferred to a delivery conveyor and conveyed away in a second imbricated formation. In the takeover region, the successive products are formed into an arched configuration, when viewed perpendicularly to the direction of their travel. This assists in ensuring that the products are delivered singly to the delivery conveyor even if the products are received at the takeover region in congruent fully overlapping pairs.Type: GrantFiled: November 13, 1989Date of Patent: August 27, 1991Assignee: Ferag AGInventors: Werner Honegger, Walter Reist

Patent number: 5029843Abstract: To hold and transport folded printed products, a belt (18), for example a steel ribbon, has separating and holding elements (19), for example flat metal plates or sheets secured thereto. The transport belt (18) with the separating elements thereon is guided about a curved guide surface (20), for example a roller, whereupon the separating elements will spread or fan out from the underlying transport belt. In this spread or fanned out position, they can accept one sheet element (11) of a spread apart folded product (1), the separating element (19) gripping that sheet element (11) between itself and the transport belt. The folded products can then be transported, in scale-like or imbricated or shingled form, to a storage position, for example by rolling up the steel ribbon (18).Type: GrantFiled: February 28, 1990Date of Patent: July 9, 1991Assignee: MAN Roland Druckmaschinen AGInventor: Ingo Kobler
