Abstract:
Linear conveyor for transferring workpieces between two consecutive positions in a throughput direction, including at least one axis extending in and linearly displaceable to the throughput direction, and a slide, disposed on and displaceable along each axis, and to which a carrier element for accommodating the workpiece is attached, each axis being telescopic and including a first axis element displaceable relative to the base, and a second axis element displaceable relative to the first axis element, on which slide is displaceably disposed, and a coupling for coupling of displacement movements of the first axis element, second axis element and slide with each other, such that when the first axis element is displaced relative to the base the second axis element is displaced relative to the first axis element and the slide relative to the second axis element in the same direction of displacement.
Abstract:
A solar cell module conveyer comprising an assembly line for intermittently feeding solar cells that constitute a solar cell module, and having machinery arranged for successively executing the working/treating steps; belt conveyers working as an inspection line which is synchronized with the assembly line to inspect the solar cell module fabricated on the assembly line through various working/treatment steps; and a transfer mechanism for transferring the solar cell module from the assembly line onto the belt conveyers.
Abstract:
A warehouse crane with individual storage areas for containing tote pans, each tote pan having handles on its opposite end walls. A pair of reversibly driven, counter-rotating endless chains is mounted on the carriage for movement about a generally horizontal, orbital path, each of the chains also having a radially inner pin and and outer pin for movement with their respective chain in orbital paths. The inner pin is pushingly engageable with the handles to push the pans into the storage areas. The outer pin is releasably engageable with the handle of the pans to pull the pans from the storage areas.
Abstract:
A fluid-operated cylinder operates a rack which is in constant mesh with a pinion gear. The pinion gear is mounted on the power input shaft of a fluid-operated jaw clutch, having toothed driving and driven elements, and arranged to engage only when the rack is driven in one direction so that the output shaft of the clutch has intermittent rotary motion in one direction. The rack extends through a stop block and includes an axially adjustable collar which abuts the stop block at one limit of movement of the rack. At the same time, a switch actuator on the rack contacts the actuator of a switch mounted on the stop block to reverse the direction of the rack. In order to adjust the driving stroke of the piston rod in the air cylinder, and hence the driving stroke of the rack, the stop block is provided with a toothed mounting surface and can be selectively positioned along a similarly-toothed mounting plate. By establishing these teeth at a pitch equal to the stroke of the rack for one powered rotation of the clutch driven member, divided by the number of teeth in the jaw clutch, the stop block may be set at any desired position along its mounting plate and yet provide efficient meshing engagement of the toothed driving and driven members. A formula for using a standard pitch cutter to obtain the exact pitch required for the stop block and mounting plate teeth is a part of the disclosure.
Abstract:
A plurality of transport lines having driving belts are driven to transport specimen racks on which a specimen container is disposed. A single driving motor having a rotating shaft, a shaft for transmitting power of the driving motor, drives the driving belt and a plurality of pulleys transmit rotation of the shaft to the belts to drive the belts.
Abstract:
A conveyor for conveying products comprises at least two drivable endless conveyor members for supporting products. The conveyor members extend substantially parallel to each other as seen from above and define a helical path. The conveyor is arranged such that under operating conditions the conveyor members have substantially equal angular speeds.
Abstract:
A component tape transport wheel, a component tape transport system and a method of operating a component tape transport system are provided, in which there is a rigid coupling between a transport wheel and an encoder wheel which is arranged on the transport wheel and whose position relative to a sensor can be determined. By this rigid coupling between the transport wheel which moves the component tape and a registration system including an encoder wheel and sensor for registering the position of the transport wheel, it is possible to register the position of the transport wheel at any time with the greatest accuracy. Even after a component tape transport system has been switched off, a determination of the absolute position of the transport wheel is possible, since the distance between two encoder elements of the encoder wheel is less than any play possibly caused by a drive of at least one of the transport wheel and an associated gear mechanism.
Abstract:
A modular conveyor system is disclosed which includes a plurality of non-contiguous, freestanding pedestals, arranged in two parallel rows. Each of the pedestals includes a support roller for contacting the bottom surface of a pallet placed on top of it, and the support rollers are connected to one another and to a drive by a series of belts. The system can easily be modified to accommodate loads of different widths, lengths and weights by moving the pedestals to correspond to the dimensions of the new load.
Abstract:
A conveyor drive mechanism has a continuous drive loop trained over first, second, and third pulleys, with the first and second pulleys disposed in driving relationship to a support bed or conveyor, and a driving facility which supplies drive torque in either direction to the third pulley, to move the drive loop and conveyor in the selected direction. Counterpoised anti-backlash motors impart equal, opposed counter-torques to the first and second pulleys to impose a predetermined level of continuous tension in the active area of the drive loop, even during reversal of the direction of the torque transmitted by the driving facility.
