Abstract:
Embodiments of the present invention provide a product transfer device. The product transfer device includes a moving assembly, a supporting assembly and a rotating assembly. The moving assembly is configured to drive the supporting assembly to move, the supporting assembly is configured such that a product is placed on the supporting assembly, and the rotating assembly is able to be connected with the supporting assembly to rotate the product placed on the supporting assembly.
Abstract:
A conveyor is powered by a rotating, generally horizontal drive tube or shaft engaged by angularly disposed trolley wheels, in which trolleys support the conveyed products or materials above the drive tube and clear of any parts of the conveyor structure that would interfere with the desired path of travel. Each of the trolleys is provided with load wheels which ride on load rails above the drive tube and associated drive wheels, thereby providing a structure upon which a platform or other support may be mounted for bearing the transported products.
Abstract:
In a drive system for an overhead conveyor, a first drive shaft presents a path of travel for a trolley, and a second drive shaft spaced from the first drive shaft provides a continuation of the path of travel. A flexible drive cable spans the gap between the shafts and interconnects the terminal end of the first shaft with the receiving end of the second shaft to transfer torque thereto to rotate the second shaft. The cable comprises spiral wound strands joined together to preclude unraveling thereof and thus the second shaft may be driven by the first shaft when their longitudinal axes are not collinear.
Abstract:
An overhead conveyor is operated at a slower speed within the treatment area or buffer than the speed of a conveyor delivering products to the treatment area or buffer and the speed of a conveyor removing products from the treatment area or buffer. Elongated products are delivered to the treatment area or buffer so that the direction of product elongation corresponds with the conveying direction and are removed from the treatment area or buffer so that the direction of product elongation corresponds with the conveying direction, particularly by being suspended from two carriages of an overhead conveyor system. Within the treatment area or buffer, the two carriages that are serially located or in tandem while traveling on the delivery conveyor and the exit conveyor, are placed on separate parallel conveyors so that the orientation of the elongation direction of the products is perpendicular to the conveying direction within the treatment area or buffer. With guides or a transfer, only one carriage of the two carriages handling a single product need be driven, and the other carriage may simply by conveyed on a gravity or drag conveyor or rail.
Abstract:
In a transfer apparatus in which a pallet is stationary when the crossing angle between the axes of rotation of a driven roller and a driving shaft is zero, and the pallet may be driven when the angle is greater than zero, a stop-start apparatus comprising a cam follower roller supported by a support member of said driven roller, a stopper block guided and supported at a stop position of the pallet so as to move to and fro in the directions of the transfer and having a notch into which said cam follower roller fits so as to keep said angle zero, a cam the proximal end of which is pivotally supported at a forward position of said stop position having a cam surface on which said cam follower roller makes a rolling contact, a spring urging said cam to a predetermined position, the distal end of said cam, in said predetermined position, being near said notch and said cam being so shaped as to increase said angle from zero to 45 degrees from said distal end toward the proximal end.
Abstract:
An intelligent driverless vehicle rolls on a track and has a pair of drive wheels which engage with a rotating drive shaft. The angular position of the drive wheels relative to the drive shaft determines the speed of the vehicle. Each vehicle has a microcomputer associated therewith, a position encoder for supplying information regarding the position of the vehicle to the microcomputer, an angular position encoder for providing information regarding the angular position of the drive wheels to the microcomputer for the computation of vehicle speed, and a drive wheel control means and associated linkage for changing the angular position of the drive wheels and thus vehicle speed in response to commands from the onboard microcomputer. The microcomputer communicates with a central computer via a bidirectional communications link. The central computer controls the speed and acceleration of each vehicle by selectively communicating with the microcomputers on board the vehicles.
Abstract:
The track for driverless vehicles has a low profile with a rail extending along one side edge portion of the track structure and a drive shaft extending along the opposite side edge portion of the track structure. The drive shaft performs the dual function of supporting wheels on one side of a driverless vehicle and driving the vehicle by frictional contact with said wheels. The rail and the periphery of the drive shaft at the 12 o'clock position thereon are substantially the same elevation.
Abstract:
A transfer mechanism for transferring a pallet from a first trackway to a second trackway is disclosed. Each trackway includes an inside track and an outside track. Preferably, the outside tracks of each trackway are connected by an arcuate connecting track. A transfer device moves the pallet from the end of the first trackway to the adjacent end of the second trackway. The transfer device includes a turntable having a track portion thereon, preferably, an inside track portion. By rotating the turntable, the track portion is first presented adjacent the end of the first trackway so that the pallet is received on the track portion. The turntable is then rotated and carries the pallet to the end of the second trackway to which the pallet is then transferred. The track portion can extend continuously around the turntable and the turntable rotated constantly so that a pallet is transferred as soon as the pallet reaches the transfer mechanism. Alternatively, a plurality of track portions can be located around the turntable and the turntable indexed to sequentially move a pallet received on a track portion. In between sequential movements, work stations located along the path of movement can perform work on objects located on the pallets.
Abstract:
A spindle conveyor for conveying workpieces, in particular vehicle wheels, having a rail system that includes at least one support rail. Multiple conveyor carriages have a chassis that can be moved on the support rail in a conveying direction and a supporting device for workpieces which is entrained by the chassis. Each workpiece can be mounted on a workpiece spindle which is part of the supporting device which has a pair of workpiece spindles mounted so as to be rotatable as a unit relative to the chassis about a vertical axis of rotation and can be moved at least into a first rotational position and a second rotational position. Also a station for treating workpieces, in particular vehicle wheels, with such a spindle conveyor which allows the workpieces to be conveyed through the station.
