An apparatus for positioning a workpiece carrier in a machining station includes at least one positioning device. The workpiece carrier is movable on a rail system and one or more machining stations are arranged along the rail system for machining a workpiece arranged on the workpiece carrier. The at least one positioning device is arranged in an area of the machining station and has fixtures for positioning and high-precision retention of the workpiece carrier with respect to a stationary reference surface. The positioning device further includes fixtures for decoupling the workpiece carrier from the rail system, and a deceleration and acceleration device for the workpiece carrier.
Device for manufacturing brushes, which mainly consists of a number of tools along which is provided a transport means (7), onto which transport means (7) is fixed at least one brush holder (12), characterized in that the device (1) is provided with coupling means which make it possible to couple and uncouple the brush holder (12) concerned to and from the transport means (7), and in that, opposite to at least one tool, a drive (35) is provided to position and move the uncoupled brush holder (12) in relation to said tool (2-6), whereby this drive (35) is provided with locking means which make it possible to fix an uncoupled brush holder (12) to this drive (35).
A combined punching and welding or punching and bonding apparatus for workpieces (1), e.g. bumpers of motor vehicles, is described. The apparatus has a punching station (3) having at least one punching yoke (4), a welding or bonding station having at least one welding or bonding tool, and a shuttle table (21) which is able to be moved between the stations and carries a workpiece holder (22). In accordance with the invention, the punching yoke (4) and the welding or bonding tools are arranged to be stationary whereas the holder (22) is mounted to be movable up and down on the shuttle table (21) (FIG. 2).
The invention relates to a method for moving paper, board and cellulosic web rolls in a roll packaging system having a plurality of roll handling stations and at least one indexing conveyor capable of operating on at least two elevation levels. According to the method, the rolls are moved in the packaging system by an indexing conveyor car, which is adapted to move synchronously at each roll handling station. The car is moved in a return motion when the indexing conveyor car is in its lowermost position. The position of the roll is measured. At least one roll is admitted onto the indexing conveyor car while having the car driven into its lowermost position (base elevation level 0) and the roll is transferred by the movement of the indexing conveyor car driven into its base elevation level 0 in such a fashion that the roll is positioned into an appropriate position in regard to the function of the roll handling stations for moving the rolls to the roll handling stations.
A positioning system utilizes a shot pin to fix the position of a grooved pallet at stations in a production line. The pallet travels along the production line under the influence of advancing feed pins. When the pallet arrives at a station, the head of the shot pin is positively urged toward the groove in the pallet until the head locks the pallet in the desired position. Simultaneously, the feed pin disengages from the pallet. When work is completed at the manufacturing station, the head of the shot pin moves away from and releases the pallet. Simultaneously, the feed pin engages the pallet. The feed pins and the shot pin operate in tandem, by moving in-phase along parallel lines in the same direction to accomplish their individual functions. The feed pins and the shot pin can operate relatively quickly without applying unnecessary torque to the conveyor or the pallet.
An interlocking transfer system includes a workstation having four or more sides, each of which is positioned at 90.degree. angles from the next adjacent side. A cam lift assembly is provided on each of the sides and a means for moving the pallets horizontally. The cam lift assembly is actuated by a reciprocating cylinder which operates to lift and lower the pallets. While pallets are lifted, they are also advanced horizontally using either an external reciprocating cylinder, a motor or by hand. The interlocking transfer system of the present invention provides high efficiency and low transfer rate. It also eliminates the need for lift and locate devices, transfer space due to traffic control, and end-to-end cross transfers. The interlocking transfer system of the present invention also provides for interchangeable fixtures.
