Presented is a door painting and drying assembly configured to hold an unfinished door for finishing by a single painter. The assembly includes an inner rim having a first rim member and a second rim member oriented perpendicular to one another, an outer rim consisting of a third rim member, and a fourth rim member oriented perpendicular to one another. The outer rim is rotatably configured over the inner rim such that the outer rim remains concentric with the inner rim during rotation. The assembly includes a beam attached across the fourth rim member, a sliding member slidably configurable on the beam. The sliding member includes slots for receiving a door support member to support a base portion of an unfinished door. The assembly further includes a vertical door support with a bracket adjustably mounted thereto to clamp to a mount attached on a hanging stile of the unfinished door.

A fixture system to be used in a vacuum chamber (16) of a vacuum treatment system, comprising, a spindle (1), a gear wheel, in this text referred to as sun wheel (2), a cylindrical object exhibiting properties that allow the gear wheel to mesh into it, in order to rotate said cylindrical object, in this text referred to as reel (3), a holding plate (4), wherein the sun wheel (2) and the reel (3) are manufactured in order to allow the sun wheel (2) to mesh into the reel (3), thereby rotating it.

Treatment system (100) for treating workpieces (102), having a treatment region (108) for receiving workpieces (102) to be treated, and a plurality of operating devices (130) for performing one or more operations on the workpieces (102) to be treated.

A robot apparatus includes: a door opening/closing robot and a controller. The door opening/closing robot includes a base, a first arm, a second arm, a third arm, and a fourth arm. The door opening/closing robot is disposed between a side surface of the vehicle body and a booth side wall. The controller sequentially performs a door opening control for controlling the door opening/closing robot such that a tool opens a door at an upstream side of a first axis in a direction of a conveyance line, a door following control for controlling the door opening/closing robot such that an opened state of the door is maintained while the vehicle body is being conveyed along the conveyance line, and a door closing control for controlling the door opening/closing robot such that the tool closes the door at a downstream side of the first axis in the direction of the conveyance line.

A door opening/closing robot includes: a base provided at a position different from a conveyance line on which a vehicle body is conveyed; a first arm attached to the base to rotate around a first axis and extending away from the first axis; a second arm attached to the first arm to rotate around a second axis and extending away from the second axis; a third arm attached to the second arm to rotate around a third axis and extending away from the third axis; and a fourth arm attached to the third arm to extend vertically and configured to vertically move a tool for holding a door of the vehicle body. At least a portion of a connection area including a distal end of the second arm and a proximal end of the third arm is positioned at a same height as at least a portion of the base.

A mounting device comprises a collar part including a plurality of ramp portions on an interior side of the collar part, and a rotatable hub part comprising a plurality of protruding portions. The collar part is positioned around the rotatable hub part. When the rotatable hub part is rotated, respective ones of the plurality of protruding portions are configured to press against respective ones of the plurality of ramp portions and exert a force on the collar part which increases a dimension of the collar part.

A system and device for temporarily joining doors together to support one another on a support surface. The device includes a first door holder having a first connector attached to a first shaft and a first mounting plate to removably affix the first door holder to one of the doors, and a second door holder having a second connector attached to a second shaft and a second mounting plate to removably affix the second door holder to a different one of the doors. The first and second door holders releasably engagable with one another to temporarily join the doors together such that the doors cooperatively support one another on the support surface while the first and second door holders are releasably engaged with one other. The system includes the device and one or more door supports to facilitate supporting the doors in an upright position on the support surface.
