1. A conveying apparatus for conveying a conveyance object, the conveying apparatus having a conveyance path along a conveying direction of the conveyance object, the conveyance path including a plurality of conveyance sections provided along the conveying direction, the conveyance object being conveyed through the conveyance path,
wherein at least two of the conveyance sections are constant-speed conveyance sections each of which conveys the conveyance object with a constant conveying speed, each of the constant-speed conveyance sections having its constant conveying speed predetermined corresponding to each of the constant-speed conveyance sections, an upstream constant-speed conveyance section being one of the constant-speed conveyance sections disposed in the upstream side in the conveying direction, a downstream constant-speed conveyance section being another one of the constant-speed conveyance sections disposed in the downstream side in the conveying direction, the upstream constant-speed conveyance section and the downstream constant-speed conveyance section having different conveying speeds from each other, the conveyance path includes an acceleration/deceleration section between the upstream constant-speed conveyance section and the downstream constant-speed conveyance section, the acceleration/deceleration section including a plurality of variable-speed conveyance sections capable of changing a conveying speed of the conveyance object, each of the variable-speed conveyance sections included in the acceleration/deceleration section has a conveying speed that is continuously accelerated or decelerated during the conveyance of the conveyance object, while the conveyance object is passing through the entire acceleration/deceleration section, the conveying speed of the conveyance object being accelerated or decelerated from the conveying speed of the upstream constant-speed conveyance section to the conveying speed of the downstream constant-speed conveyance section, the conveying speed and the conveyance acceleration/deceleration are controlled to be identical between an upstream conveyance section conveying the conveyance object and a downstream conveyance section disposed in the downstream side of the upstream conveyance section when the conveyance object is transferred from the upstream conveyance section to the downstream conveyance section, and after the conveyance object is conveyed to the downstream conveyance section, a conveying speed of the variable-speed conveyance section disposed in the upstream side is accelerated or decelerated so as to approach a conveying speed of the upstream constant-speed conveyance section. |
