Abstract:
A transferring speed-change device is provided between an upstream-side stage and a downstream-side stage which are different from each other in conveying speed and conveying pitch. A speed change pinion is meshed with a transferring rack at the same speed as that of an upstream-side pinion; is maintained at the same speed as that of the upstream-side pinion until a main rack is disengaged from the upstream-side pinion; and is used to drive the carrier after the main rack is disengaged from the upstream-side pinion. The speed change pinion is caused to have the same speed as that of a downstream-side pinion immediately before the main rack meshes with the downstream-side pinion; and is maintained at the same speed as that of the downstream-side pinion until the transferring rack is disengaged from the speed change pinion.

Claim (Index 1):
A conveyance apparatus comprising:\n carriers movable in a conveyance direction along a track and configured to support objects to be conveyed; racks having rack teeth, the racks being provided to the carriers and extending in the conveyance direction; a plurality of pinions configured to mesh with each rack and arranged along the track; a mechanical connection section connecting the plurality of pinions and extending in the conveyance direction; and a drive unit configured to drive the mechanical connection section, the conveyance apparatus being for use in a production line including stages which are different from one another in a conveying speed for the carriers and a conveying pitch therebetween, wherein the mechanical connection section is subjected to speed change via a speed change machine, between an upstream-side stage and a downstream-side stage which are different from each other in the conveying speed for the carriers and the conveying pitch therebetween, a transferring speed-change device is provided between the upstream-side stage and the downstream-side stage,\n the transferring speed-change device is connected to the mechanical connection section on the upstream-side stage or the mechanical connection section on the downstream-side stage, \n the transferring speed-change device includes\n a speed change pinion configured to be subjected to speed change during movement of each of the carriers, and \n a mechanical-type speed change mechanism configured to mechanically perform the speed change in the speed change pinion, \n \n on the upstream-side stage,\n the carrier is moved in a state where the rack is meshed with an upstream-side pinion among the pinions, \n on the downstream-side stage,\n the carrier is moved in a state where the rack is meshed with a downstream-side pinion among the pinions, and, \n between the upstream-side stage and the downstream-side stage,\n the carrier is moved in a state where the speed change pinion subjected to the speed change by the mechanical-type speed change mechanism of the transferring speed-change device, is meshed with the rack provided to the carrier or a rack different from the rack provided to the carrier, with a speed of the speed change pinion being changed from a speed of the upstream-side pinion to a speed of the downstream-side pinion within a period from start of meshing of the speed change pinion with the rack or the different rack to end of the meshing.
