Abstract:
An improvement in a conveyor system having sets of laterally spaced drive and idler wheels, a plurality of at least two different size carriers for containing articles to be worked on and for operating on the same conveyor system; and two runners attached to the sides of each carrier, one runner on each side thereof, each runner having at least one riding surface for supporting the carrier on the wheels, the runners of each carrier being attached and sized and shaped in such manner as to effectuate such support, whereby two different size of carriers can be used at the same time on a single conveyor system. Each carrier having a lower surface, separate from the runners, for handling, storage and stacking of the carriers. The runners are removably attached to the carriers. The runners may be connected to the carriers at an angle with respect to the lower surface of the carriers. The runners may be the same length as the carriers, shorter than the carriers, or longer than the carriers. At least some of the runners may have two different riding surfaces spaced different distances apart, so that the same carrier can be used on different conveyor systems having different lateral wheel spacing. The runners can be selectively removably attached at two different locations on the carrier. The means for removably connecting the runners to the carriers may include snap-in devices.
Abstract:
In order to facilitate production of cans (3,103,103'), in particular of aerosol cans, magnetic conveyors (6,8) and magnetizable pallets (7,107,107') are provided, instead of chain conveyors including mandrels, in plants for producing containers. The cans (3,103,103') are fixed to the magnetizable pallets (7,107,107') and are passed to or through processing stations, for example, by magnetic belt conveyors (6,8). The pallets (7,107,107') are connected to a connecting portion (132) projecting from the can bottom (130) which may be inserted into a connection opening (117) of the pallet (7,107,107') by a riveting operation. By appropriately arranging the conveying surface (8) of the magnetic conveyor (6,8), the cans (3,103,103') may be oriented at will on the pallets (7,107,107') which are magnetically supported. The can opening is always freely accessible during conveying. In order to compensate for variations of through-put of the plant by simple means, belt conveyors having accumulation zones (46) are provided.
Abstract:
A curved conveyor section comprises a generally flat substantially horizontally disposed curved belt-supporting bed having first and second opposite ends and first and second direction reversing members disposed at the first and second opposite ends, respectively. A continuous loop curved conveyor belt has arcuate inner and outer edges with a common substantially vertical centre axis and is mounted on the belt-supporting bed in looped relation around the direction reversing members so as to have an article carrying portion disposed above the belt-supporting bed and a return portion disposed below the belt-supporting bed, thus defining a looped path for the conveyor belt and presenting a substantially horizontal article carrying top surface. A motor driven continuous loop drive chain or belt is oriented in a substantially horizontal plane and has a plurality of driving members disposed along its looped length. A plurality of driven receptors are securely mounted on the curved conveyor belt along its looped path. The driving members drivably engage a consecutive subset of the plurality of co-operating receptors, which consecutive subset is disposed at one of the article carrying portion and the return portion of the curved conveyor belt, so as to thereby impart a driving force to the co-operating receptors, thus causing selective movement of the curved conveyor belt along its looped path.
Abstract:
A pallet type transfer device utilized to transport parts or components along a conveyor-type assembly line is disclosed. The pallet type transfer device includes a body member having a rear bumper member with a pair of oppositely disposed idler wheels rotatably mounted thereto and having a front bumper member attached to the front surface thereof. The top surface of the rear bumper member is inclined upwardly towards the rear surface of the body member. Parallel, longitudinally extending, spaced-apart complementary grooves are provided on the bottom surface of the body member, each groove having a conveyor belt received therein. When a "moving" pallet type transfer device contacts a "stopped" transfer device along the assembly line, the front bumper of the "moving" transfer device contacts and moves laterally on the inclined top surface on the rear bumper member on the "stopped" transfer device causing the body member of the "moving" transfer device to move slightly upwardly resulting in the complementary grooves on the bottom surface thereof becoming disengaged from the conveyor belts, thus minimizing or eliminating wear to the belts and to the bottom surface of the "moving" transfer device. The conveyor belts continue to move within grooves provided within the idler wheels, however, the belts do not contact the complementary grooves provided in the bottom surface of the body member of the "moving" transfer device which has now been stopped.
