Abstract: A work stopping apparatus according to this invention includes a swing unit pivotable about a first pivot shaft between an abutment position and a retracted position, and a driving unit pivoting the swing unit. The swing unit includes a swing portion and a movable portion including a work abutment portion. The movable portion is pivotable about a second pivot shaft parallel to the first pivot shaft. A distance between the first pivot shaft and the work abutment portion becomes short along with pivoting motion of the swing unit from the abutment position to the retracted position.

Abstract: This invention provides a transport unit that includes driving rollers arrayed in the transport direction of a work, and when the work transported by the driving rollers reaches a predetermined stop position, stops movement of the work. The driving rollers include at least one first driving roller, and at least one second driving roller arranged on the side of the predetermined stop position in the transport direction with respect to the first driving roller. The first driving roller is a roller capable of idling on a driving shaft. The second driving roller is a roller incapable of idling on the driving shaft.

Abstract: A stopping apparatus according to the invention includes a swing unit pivotal about a first pivot shaft between an abutment position in which the swing unit abuts against a work to stop conveyance of the work and a retreat position, a driving unit, and an elastic member applying a biasing force to the swing unit in a direction in which the swing unit is located at the abutment position. The swing unit includes a swing portion pivotal about the first pivot shaft and a movable portion including an abutment portion abutting against the work. The movable portion is pivotally connected to the swing portion. The movable portion pivots relative to the swing portion such that a distance between the first pivot shaft and the abutment portion becomes short along with a pivot motion of the swing unit to the retreat position.

Abstract: This invention provides a conveying apparatus which conveys a workpiece. The conveying apparatus includes a pallet which supports the workpiece, a conveyor which supports one side of the pallet in a direction perpendicular to a conveyance direction from below the pallet, and includes a conveyance roller for conveying the pallet and a driving source for driving the conveyance roller, and a heaving suppression guide member which extends along the conveyor, abuts against the other side of the pallet in the direction perpendicular to the conveyance direction, and suppresses heaving of the pallet.

Abstract: An operation apparatus of this invention includes a main pallet and a sub pallet detachable from the main pallet, and can convey a work and a part. The operation apparatus includes a lifting mechanism disconnecting, from the main pallet, the work placed on the main pallet and lift/lower the work; a moving mechanism detaching, from the main pallet, the sub pallet attached to the main pallet and lift/lower the sub pallet; a rotation mechanism holding the work lifted to a work operation region by the lifting mechanism; and an operation unit extracting the part from the sub pallet lifted to a part preparation region by the moving mechanism and assembling the part to the work.

Abstract: This invention provides a lifting apparatus which holds a work by clamping the work vertically, and lifts the work. The lifting apparatus includes upper and lower clamping units, a guide mechanism which guides lifting movements of the upper and lower clamping units, a driving mechanism which drives the lower clamping unit to lift along the guide mechanism, and a stopper which is set so that the upper clamping unit is stopped before the lower clamping unit reaches a downward movement lower limit during the downward movement of the units, and which defines a downward movement lower limit of the upper clamping unit.
