US Patent:

46483250, Mar 10, 1987

Filed:

Jun 20, 1985

Appl. No.:

6/747054

Inventors:

Stanley K. Gutekunst - Nazareth PA
Russell H. Scheel - Easton PA
Barry L. Ziegenfus - Saylorsburg PA

Assignee:

Heico Inc. - Mendota IL

International Classification:

B61B 1312
B61L 304

US Classification:

104166

Abstract:

A linear drive unit having a carriage reciprocal along a path of travel and having a plurality of pairs of angularly adjustable drive wheels engaging opposite sides of a rotatable drive tube whereby rotation of the drive tube imparts linear motion to the carriage. The angle of the drive wheels is controlled by a remotely-operable air motor mounted directly on the carriage. A plurality of cams provide controlled acceleration and deceleration of the carriage adjacent the ends of its path of travel. A selectively operable inching control is remotely operable to provide for a reduced speed of travel of the linear drive unit. The linear drive unit is easily associated with the mass to be moved, such as a travelling hoist, and the forces generated by opposed drive wheels compressively engaging the drive tube are self-contained within the carriage. Additional control cams can be provided along the path of travel, if additional stopping locations are desired.

Assignee:

S I Handling Systems, Inc. - Easton PA

International Classification:

B61J 110
B60S 1302

US Classification:

104 48

Abstract:

A shuttle vehicle reciprocates between sets of tracks for driverless vehicles. The linear movement of the shuttle vehicle causes a turntable on the shuttle vehicle to rotate. The turntable is adapted to support a driverless vehicle to be transported from one set of tracks to another.

International Classification:

B61B 1312

US Classification:

104166

Abstract:

A carrier system having a carrier movable along a path as defined by a trackway and driven from a rotatable drive tube by means of one or more drive wheels which can be adjustably angularly related relative to the drive tube for determining the direction and speed of carrier travel. The carrier has a multi-function accumulation rod operable in both accumulation of carriers as well as at a stop station along the path of travel. The accumulation rod is movable to control the angular position of the drive wheel to achieve stopping of the carrier at the stop station as well as to cause accumulation of one carrier behind another. The accumulation rod is operable in either direction of travel of the carrier to affect accumulation. Reverser structure operable at the end of the path of travel of the carrier causes a shift in the orientation of the drive wheel and the accumulation rod whereby the carrier will travel in an opposite direction and with the accumulation rod functioning in an accumulation mode in the reverse direction of travel.

Inventors:

Russell Scheel - Easton PA

Assignee:

SI Handling, Inc. - Easton PA

International Classification:

B61B 1312

US Classification:

104166

Abstract:

A driverless vehicle has an inverted U-shaped body with the bight being a horizontal load supporting surface. A pair of wheels is supported by each leg of the body. A friction drive wheel for contact with a drive shaft is supported by the body. An accumulation bumper is provided adjacent a front end of the body and a cam is supported adjacent the rear end of the body.

Assignee:

Heico Inc. - Mendota IL

International Classification:

B61J 110
B61B 1500

US Classification:

104166

Abstract:

A lightweight car-on-track system having a pair of spaced-apart rails and an associated rotatable drive tube with a captive carrier movable along the rails and having a drive wheel in driving engagement with the rotatable drive tube. The drive wheel is spring-loaded against the rotatable drive tube and the capture of the carrier to the rails results in a controlled drive force achieved regardless of the weight of the carrier or of a load supported thereon. The system is made up of a selected number of modular units, each having adjustably mounted frame members supporting opposite ends of a rail section and a drive tube section. Adjustable mounting of frame members to an alignment plate assures alignment between rail and drive tube sections when assembling the system. A transfer device is utilized for transferring a carrier from the end of one track section to the spaced-apart end of another track section with the transfer device being oscillatable about a pivot axis. A drive tube for each track section has a generally frusto-conical end extending beyond an end thereof which coact with the drive wheel of a carrier to impart motion of a carrier onto and off the transfer device.

US Classification:

104250

Abstract:

A precision stop assembly is provided for causing a driverless vehicle to stop at a predetermined location with an accuracy. +-. 005 inches in three planes. The assembly includes structure for slowing a vehicle down and then elevating the vehicle so that its support wheels lose contact with tracks while simultaneously guiding the vehicle to a precise orientation.

Inventors:

Russell H. Scheel - Easton PA

Assignee:

SI Handling Systems, Inc. - Easton PA

International Classification:

B61B 1312

US Classification:

104166

Abstract:

A control device is provided for controlling the speed of a vehicle used in a conveyor system wherein the vehicle moves along a track. The control device has a generally straight section between a first angled section having a cam surface for deceleration and a second angled section having a cam surface for acceleration in a controlled manner. The control member is supported for movement between operative and inoperative positions. A motor is provided for moving the control member from an inoperative position to an operative position. The control member is held in its operative position by a cam follower on the vehicle. When the cam follower loses contact with the control member, the control member moves to its inoperative position by gravity.
