| 21 | Pillow Block Bearing for Shaft Driven Conveyor System with Self Aligning Feature | US12233995 | 2008-09-19 | US20090078149A1 | 2009-03-26 | CHARLES PAUL TABLER |
| A rotating shaft drive system is configured to propel a load along a conveying path of an overhead conveyor system. A stationary frame extends along the conveying path and supports the rotating shaft drive system. A movable carriage is suspended from the stationary frame and engages with a rotating shaft of the shaft drive system to propel the carriage and the load. The rotating shaft comprises a plurality of shaft segments supported pillow blocks at each end of the rotating shaft segments, and the pillow blocks create a gap between adjacent shaft segments. The movable carriage has at least one canted driven roller configured to engage with adjacent rotating shaft segments and to create a helical loci of tractional engagement that provides sufficient drive force to propel the carriage and the load along the conveying path. The drive system is further configured to provide continuous propulsion as the canted driven roller moves across the gap between adjacent shaft segments. | ||||||
| 22 | Coupling device in overhead conveyor system | US10514989 | 2003-05-22 | US07421953B2 | 2008-09-09 | Hardy Johansson; Palle Johansson |
| A device for an overhead conveyor system of the type where a plurality of carriages (7) by contracting a rotating drive shaft (5) are propellable along a rail (2). The device comprises an operating arm (28) arranged in connection with a first carriage (7b) and adapted to actuate, by turning about an axis of rotation (26), a power transmission element (24) to disconnect the carriage from contact with the drive shaft, and an angled supporting surface (20) arranged in connection with a second carriage (7a). One end of the operating arm (28) is further adapted, when said carriages (7a, 7b) are moved towards each other, to contact said angled supporting surface (20) and be moved along the same, so that the operating arm (28) thus performs a turning motion and disconnects said first carriage (7b). According to the invention, the drive of the carriage will thus be interrupted as soon as its operating arm is contacted with the supporting surface of an anteriorly situated carriage. In this manner, carriages can be buffered. | ||||||
| 23 | Conveyor system with an overhead load carrier | US09856268 | 2001-05-18 | US06457418B1 | 2002-10-01 | Anders Persson |
| The invention relates to an overhead conveyor system which includes a rail, at least one carriage which is provided with wheels and which is adapted to run along the rail and support a load suspended from the carriage, a rotatable drive shaft which extends along the rail and is located perpendicularly above the rail, and a drive arranged on each carriage and adapted to drive, in contact with the drive shaft, the carriage along the rail. The drive includes at least one wheel which is inclined relative to the longitudinal direction of the drive shaft and has a contact surface spring-loaded against the drive shaft, the spring load of the drive being independent of the load suspended from the carriage. | ||||||

| With respect to an overhead conveyor of the type wherein a carriage travels along a rotatable generally horizontal drive shaft by being supported on the top periphery of the drive shaft through skewed driven rollers, carriage construction is minimized by forming a portion or all of the carriage from a uniform cross sectional shaped elongated member extending through skewed apertures within the hub of one or all of the driven rollers. | ||||||
| 25 | Movable workbench and an assembly line device using the workbench | US817920 | 1997-06-24 | US5839721A | 1998-11-24 | Masaaki Kobayashi |
| A movable workbench 6 has a work board 7, second casters 8 attached on one side of the back of the work board, and first casters 9 attached on the other side thereof. The first casters 9 can rotate freely around an axis of rotation 91 perpendicular to the back of the work board 71, and have rollers 92 and 93 which can rotate freely around axes of rotation 92a and 93a respectively which are inclined symmetrically with respect to the axis 91. The rollers 92 and 93 also have plates to prevent running off 94 and 95 respectively. Because the pair of rollers 92 and 93 are put on a cylindrical rail 35 and roll along the rail, the movable workbench 6 can be moved along the rail by manpower. Since each of the casters can rotate freely, the casters can be moved along an arc-like line. In addition, the plates 94 and 95 prevent the workbench 6 from running off the rail even if the workbench is inclined. Accordingly, the movable workbench has a simple construction and can be manufactured inexpensively, and makes it possible to construct an assembly line device in which an assembly line can be extended or changed easily. | ||||||

| 29 | Conveyor transfer mechanism | US408816 | 1982-08-17 | US4498397A | 1985-02-12 | Gilbert Fuchs; Norman Crowley; Randall Wink |
| 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. | ||||||

A buffering arrangement for an overhead conveyor system comprising a twin-track buffering zone having a first track (2a) and a second track (2b) extending along each other, and an intersection (15) with a guide (16) for guiding one carriage (7a) of each conveyor unit (14) onto said first track (2a) and another carriage (7b) of each conveyor unit (14) onto said second track (2b). The twin-track buffering zone includes a first straight segment (17), and a first curved segment (19) wherein said first track (2a) forms an outer curve and said second track (2b) forms an inner curve. Along the straight segment, a first drive element portion (18) is arranged to propel said front carriage (7a) along the first track (2a) with a buffering speed (B). Along the first curved conveyor segment (19) a second drive element portion (20) is arranged to propel said front carriage (7a) along the first track (2a) with an accelerated speed (C), greater than said buffering speed (B). With this arrangement, the buffering zone can include curved segments, and can therefore be more easily adapted to the space available for the buffering zone.
