A pallet changer such that deformation of the pallet at the time of clamping the pallet is suppressed and drawing-in and drawing-out operations of the pallet with respect to the pallet clamping apparatus is eliminated to contribute to high speed pallet exchange is provided. Holding portions 41 projected toward an bore portion 34 opened to the central portion at the lower surface of the pallet 30 are provided. Engagement portions 37 which can be engaged and withdrawn or disengaged with respect to...

The invention relates to a production line (1) for assembling and/or processing components (3) transported on workpiece holders (2), incorporating several conveyor sections (5, 6a, 6b, 6c) disposed one after the other, each of which has at least one separate forward feed mechanism (15; 51) which is independent of the adjacent conveyor sections (5, 6a, 6b, 6c) and at least one co-operating guide mechanism with two oppositely lying guide tracks (20), along which the workpiece holder (2) disposed b...

A toothbrush handling device for handling of toothbrushes during the manufacturing process. The device is a rigid toothbrush holder with fixed dimensions which is easily transported in a conveyor type apparatus. The holder is formed with a generally toothbrush-shaped portion and terminates in at least one cavity suitable to hold at least the head portion of the toothbrush such that the bristles do not contact any interior surface of the cavity. If only one cavity is present, it is large enough t...

The invention concerns a work carrier changeover device for machine tools, with a work carrier transfer device for moving the work carrier (16) between a machining station (15) and a tooling station (21). The work carrier transfer device has a coupling element (25) rotatable around a vertical axis and two opposing coupling points (26, 27) for the coupling of work carriers (16). The coupling element (25) is pivotably mounted at free end section of a swivel arm (24) capable of swivelling around a ...

A rotatable pallet changing apparatus, a system and a method are provided in which the rotatable pallet changing system has a rotatable bed having a first pallet and a second pallet side-by-side and set on tracks. A first and a second workpiece may be set upon a first pallet and a second pallet, respectively. As the first pallet with the first workpiece is drawn into a machining center to be worked upon, the second workpiece may be added to the second pallet. When the first workpiece on the firs...

A pallet changer is rotatable around a pin which releasably engages a shop floor. A pneumatic load module assembly creates a cushion of air which supports the pallet changer for manual rotation. The pin can be released from the floor to allow linear horizontal movement of the pallet changer or the cushion of air when it is necessary to repair, refurbish or replace equipment adjacent the pallet changer.

An adjustable pallet for supporting work pieces having a carriage rod mounted on the pallet; and a pair of support member. At least one the support members is mounted for travel on the carriage rod. The support member, which is mounted for travel, includes a spring having a helical portion which encircles the carriage rod and engages the carriage rod when the spring is relaxed, thereby fixing the position of the support member on the pallet, and disengages from the carriage rod when the spring i...

A control for moving a pallet relative to first and second base plates including four carriages that are rotatably supported on the second base plate by second rollers and which can be moved by pistons that are mounted in cylinders that are attached to the second base plate. The first plate has downwardly extending members formed with slanted slots and each of the four carriages have first rollers received in the slots so that as the pistons are moved in the cylinders the first base plate and th...

A machining system is provided which includes a selected number of machining centers for selectively cutting or machining metallic parts, the system further including a rack structure for providing inventory storage for parts which are to be machined by the centers. There is further provided a part transport device for moving a given one of the parts in a first part flow loop when the given part is in a condition which enables the part to be readily moved around a plant or other manufacturing es...

A pallet system for changing pallets at a work station which has a carousel mounted on a base and has a trolley laterally moveable which supports a turntable that is rotatably moveable. Pallets which hold workpieces are mounted to rails on the turntable. Locking devices for the trolley, the turntable and the pallets are provided. Pivoted rails allow the pallets to be moved between the carousel and the work station.
