An elongated housing 10 has a positioning rod 13 located therein, slidable with respect to the housing. A guide rod 14 slides parallel to the positioning rod. The guide rod and the positioning rod are coupled together by end elements 38, 39. The housing 10 is formed with recesses or bores 11, 12 for the positioning rods 13, 14 and additionally is formed with bores to transfer energy at power level for subsequent positioning or operating units, as well as to permit transfer of control signals. The positioning rod can be operated by fluid pressure by coupling a piston, slidable within its operating space and forming a cylinder, or by an electrical rack-and-pinion or worm screw drive. The unit is compact and closed towards the outside, suitable for modular association with similar or other units, and devoid of external flexible hoses or cables interfering with access thereto.

Chain conveyor for workpieces and workpiece carriers with a roller chain (18) which includes a roller (28) at every second link joint. Spring elements (36), which cover the free spaces between the rollers (28) towards the top, are caught on hinge pins (24) lying between the rollers (28). Chips, screws or the like small parts are thereby prevented from reaching the free spaces between the rollers (28) and damaging the support surfaces of stopped workpieces or workpiece carriers.

In apparatuses of the generic type, single point modules are provided which can transfer only the transport wagons arriving from one point branch optionally into one of the two other point branches. It is achieved by the development of the point modules according to the invention as T-shaped double point modules (40) that each point branch (42, 44, 46) can be connected optionally to one of the other two point branches, which results in a construction of a network transport path system of a simpler construction which requires less space and provides a better overview. For narrowing the spacing of parallel transport path routes (76, 80), point modules (72) are proposed whose branch angle is less than 90.degree., preferably 45.degree.. Apparatus with flexible transport path and assembly systems in industrial production plants are a preferred application sector.

A device for lifting work pieces and work piece supports from a conveyor belt and for supporting against operating pressure includes a base, a lift table and a slide disposed therebetween. The slide is movable by means of an adjustment drive between a first end position and a second end position. At least one of the parts is provided with lift faces which are formed by a peripheral segment of a cylinder element. Counter faces which cooperate with the lift faces are formed by rotatably mounted lift rollers which in the operating position of the lift table are released from pressure by supporting faces provided on the base, the lift table and the slide. This device is characterized by short adjustment paths of the slide, low friction faces and also by the end positions of the slide which should not be exactly defined and maintained.
摘要:
A method is described for classifying a clutch unit for a drivetrain of a motor vehicle, wherein the clutch unit has at least one friction clutch for the controllable transmission of a torque from an input element to an output element and has an actuator for actuating the friction clutch. Here, the clutch unit is controlled on the basis of a predefined characteristic curve which describes a predefined dependency of the clutch torque to be transmitted on an actuator control variable.
摘要:
A linear unit for transferring objects, particularly for removing workpieces from a linear conveying track, comprising vertically and horizontally movable grippers for grasping the objects and comprising a gripper carriage which is movable between a pick-up position and delivery position and having first and second carriage parts, wherein the movement sequence of the grippers for receiving the objects in the pick-up position and for depositing the objects in the delivery position is effected due to relative movement of the second carriage part with respect to the first carriage part.
摘要:
A transporting device has at least one autonomous workpiece carrier provided with an electric device and a drive control, and a path system provided with a plurality of stations. The workpiece carrier is provided with a unit for determining the operational parameter of the workpiece carrier and reacting to the deviation of the operational parameter from a predetermined value.

摘要:
A conveyor comprises an endless, flexible conveying element, a drive unit for driving the conveying element, a deflecting unit for reversing direction of movement of the conveying element, and at least one tensioning device. The tensioning device includes a displaceable tensioning element engaging the conveying element, a tensioning spring biasing the tensioning element toward the conveying element, and a unidirectional blocking mechanism which blocks a displacing movement of the tensioning element in a direction opposite the effective direction of the tensioning spring for automatic readjustment of the conveying element while maintaining the possibility of the reversing operation. The blocking action of the blocking mechanism can be cancelled by an unlocking key, and the tensioning device can be slid back into a locking position to allow the disassembly of the conveying element.
