Patent number: 4987991Abstract: A system for changing the speed of conveyed sheets while maintaining the sheets in register includes a speed changing belt operating at a constant speed to present a radial outer surface portion which travels over a pulley and into tangent contact with the surface of the sheet traveling at a speed equal to the velocity of the incoming sheets. A portion of the speed changing belt includes an acceleration lobe positioned to engage the trailing portion of the sheet and to provide a continuously increasing radius at the tangent contact portion as the belt travels around the pulley whereby the outer surface velocity of the lobe and the sheet in contact therewith continuously increase from the incoming speed to a desired second speed.Type: GrantFiled: March 30, 1990Date of Patent: January 29, 1991Assignee: Marquip Inc.Inventor: Carl R. Marschke

Patent number: 4938340Abstract: Rod-like articles, particularly cigarettes or cigarette filter rods, are conveyed in a stream in a direction transverse to their lengths at a speed which is progressively reduced, so that the height of the conveyed stream is increased. Prior to the reduction in conveyance speed the speed of individual articles is increased briefly to avoid damage from following articles. The speed reduction takes place in a path having divergent boundary walls.Type: GrantFiled: August 15, 1984Date of Patent: July 3, 1990Assignee: Molins PLCInventors: John K. Horsley, John E. Nixon

Patent number: 4934510Abstract: A supply conveyor has a support surface for conveying glass bottles supported at their bottoms in upright condition and feed them sequentially to a gap between the supply conveyor and a delivery conveyor, also having a support surface for conveying the bottles supported at their bottoms in upright condition and feeding them away from the gap. An intermediate conveyor accelerates the bottles across the gap from the slower speed of the supply conveyor to the high speed of the delivery conveyor and deposits them on the delivery conveyor at the requisite high speed an in upright condition and, as well, cause the bottles to be deposited on the delivery conveyor in properly spaced relation to allow the requisite inspection of the bottles to be made.Type: GrantFiled: April 22, 1985Date of Patent: June 19, 1990Assignee: Thomassen & Drijver-Verblifa N.V.Inventor: Pieter H.

Patent number: 4822447Abstract: A high-frequency welding installation for welding particularly plastic material parts includes at least two work stations and one feed station arranged in linear succession and trays on which work pieces are conducted through the stations by means of a transport system in a single direction and are returned into the initial station in the opposite direction outside of the stations in an essentially vertically offset plane, wherein the trays are arranged during the transport in both directions always with the working side facing upwardly. Four essentially straight-line transport units are provided. The first unit is a feed unit, the third unit is a return unit, and the second and fourth units are each vertical elevators. The return unit is arranged essentially parallel to the work unit and at least the return unit operates at a higher transport speed than the feed unit.Type: GrantFiled: June 26, 1987Date of Patent: April 18, 1989Inventor: Hans Obermeier

Patent number: 4771877Abstract: A feeder mechanism for feeding load items in a predetermined spaced relationship into a loading station of a carton loading machine comprises at least two conveyors which move at different speeds along the same path and elevator ramps on each of the conveyors. The primary conveyor has a forward run mounted for movement at a first predetermined speed in a forward direction. The forward run has an input end for receiving load items and it extends forwardly from the input end into a spacing station. The secondary conveyor has a forward run mounted for movement at a second speed in the forward direction which is faster than the first speed. At least a portion of the forward run of the second conveyor is located adjacent and coextensive with a portion of the forward run of the primary conveyor in the spacing station. A plurality of elevator ramps are mounted on the secondary conveyor at longitudinally spaced intervals therealong.Type: GrantFiled: May 5, 1987Date of Patent: September 20, 1988Assignee: H. J. Langen & Sons LimitedInventor: Marinus J. M. Langen

Patent number: 4717013Abstract: Apparatus for delivering singularized stacks of paper sheets to a packing machine has a first conveyor which intermittently receives groups of several abutting stacks and is intermittently driven by a variable-speed electric motor to advance the groups onto the individual endless bands of a gathering conveyor which serves to accumulate the groups into a row of abutting stacks ready to be singularized and delivered to the packing machine. The bands of the gathering conveyor are normally driven at a constant speed by a prime mover which further drives a first encoder serving to transmit a first signal whenever the bands cover a unit distance. A second encoder generates second signals whenever the motor is on and the first conveyor covers the same unit distance. The motor can also drive the bands at a speed higher than that at which the bands can be driven by the prime mover whenever the speed of the first conveyor exceeds the speed of the bands.Type: GrantFiled: August 21, 1986Date of Patent: January 5, 1988Assignee: E.C.H.

Patent number: 4604704Abstract: A multi-sectioned conveyor for receiving serial products from a supply conveyor, inspecting and rejecting out-of-tolerance products and adjustably conveying the products so as to establish a predetermined spacing therebetween, before transferring the products from supporting belts to the individual flights of a pusher member containing conveyor and from which the product flow is synchronized relative to an infeed conveyor to a wrapping station. The feeder comprises a microprocessor controlled, DC driven accumulation, transition and backlog conveyors, along with wrapper driven separation, transfer and infeed conveyors.Type: GrantFiled: September 10, 1984Date of Patent: August 5, 1986Assignee: Doboy Packaging Machinery, Inc.Inventors: Fred W.

Patent number: 4550822Abstract: Printed products arriving in an imbricated product formation are fed to spaced gripper units of a transport device by a belt conveyor. The conveying direction of the belt conveyor forms an acute angle with the transport direction of the transport device. The transporting rate or velocity of the belt conveyor is greater than the transporting rate or velocity by the transport device. Each gripper unit comprises a stationary clamping jaw, a pivotable clamping jaw, and a plate-shaped stop. The pivotable clamping jaw is pivoted against the action of a closing spring by a cam structure or the like. The printed products are first accelerated and then pushed into the open gripper mouth until abutting the stop in order to thereby align the printed products at the region of their leading edges. At the region of their trailing edges, the printed products remain under the conveying action of the belt conveyor at least until the gripper units are closed.Type: GrantFiled: February 28, 1983Date of Patent: November 5, 1985Assignee: Ferag AGInventor: Jacques Meier

Patent number: 4549647Abstract: Apparatus is disclosed for transferring solid articles such as biscuits, without changing their position or spacing, between an upstream machine discharging the articles at a constant speed for a downstream machine having a higher rated speed with short dwells. The articles are fed from the upstream machine to a first linear conveyor and a second, parallel linear conveyor feeds in the opposite direction the articles towards the downstream machine. A circular turntable or semicircular conveyor has a semicircular path of movement between the first and second conveyors for transferring the articles therebetween. The turntable or semicircular conveyor is mounted for translation on a carriage parallel to the first and second conveyors.Type: GrantFiled: August 17, 1982Date of Patent: October 29, 1985Assignee: Biscuiterie Nantaise-BNInventor: Lionel Cosse
