Patent number: 4710093Abstract: The invention concerns a manipulator (1) which is able to automatically receive the tool holder (7), to clamp it and to set it down again, in order thus to make possible a rapid changing of different tools. For this purpose, the last drive element (6) of the manipulator (1) as well as the tool holder (7) are provided with coupling parts (8,9) and with cooperating screw systems (16,17). The manipulator-side screw system (17) is mounted via an operating element (11) for rotation at a second operating element (10) which forms a rotation barrier (13) with the tool holder (7) as the coupling parts (8,9) come together. The screwing process is actuated by rotation of the last drive member (6). The two operating elements (10,11) are furthermore non-rotationally connected through a fixing mechanism (20). This rotation lock is abolished as soon as the rotation barrier (13) between the operating part (10) and the tool holder (7) becomes effective.Type: GrantFiled: February 7, 1986Date of Patent: December 1, 1987Assignee: KUKA Schweissanlagen & Roboter GmbHInventors: Ernst Zimmer, Botho Kikut

Patent number: 4710122Abstract: The invention relates to a machine for manufacturing flat bodies in a continuous linear process. This is attained by the intermittent forward movement of the moulds on a closed circuit static runway, passing through the various operative steps for forming the pieces. The runway defines a rectangular trajectory and the moulds are square with bevelled vertices forming vertical channels for the actuation of centering elements. The moulds cover the totality of the circuit with the exception of two spaces at the diagonally opposed angles. Each straight section is provided with a pusher facing a buffer for the simultaneous and combined action until each mould reaches the end of the circuit. At a point of the circuit there is a fixed hopper beneath which there reciprocally moves a carriage bearing a metering hopper. Once the pieces have been formed they are removed by a pneumatic extractor having a multiple suction head.Type: GrantFiled: March 7, 1986Date of Patent: December 1, 1987Inventor: Eliseo H. Villanueva

Patent number: 4710358Abstract: To change the surface tension of cup-like containers by means of corona treatment, the containers are placed on a mandrel and are moved by drive wheels in such a way that the cup-like container is caused to roll off on the mandrel with the inside of the wall. Via an electrode the discharge current is supplied across the discharge gap to the cup-like container and it is removed via the mandrel, which is connected as counter-electrode. To avoid a discharge gap on the inside of the wall, the mandrel has connected to it a guide shoe which always applies against the inside of the wall.Type: GrantFiled: July 9, 1986Date of Patent: December 1, 1987Assignee: Polytype AGInventor: Hans Neuhaus

Patent number: 4706510Abstract: The invention relates to the production of a guidance system (9, 14) for two machine parts (1, 2) which are movable relative to each other and are interconnected through this guidance system. To protect this guide track (9) disposed on the first machine part (1) from the track dust, grease, oil and the like, it is disposed in an almost completely closed guide channel. This guide channel is accessible only from the top through a slot engaged by guide elements (14) of the other machine part (2). The slot is covered on the one hand by the housing of machine part (2), and in the area outside of this housing it is closed by a belt (4). The guide track (9) is thus closed to the outside in any position of the machine part (2). If a toothed belt drive (3) is used, the toothed belt (4) acts as driving and covering element at the same time.Type: GrantFiled: January 28, 1986Date of Patent: November 17, 1987Assignee: Kuka Schweissanlagen & Roboter GmbHInventor: Ernst Zimmer

Patent number: 4704897Abstract: A method of locating a leak in a block of pipes comprises the filling of the pipe with inert gas and the sealing of the pipe. Thereafter, suction is applied to the pipe for drawing air or atmospheric gas into the pipe through the leak. Care is taken to insure that the block of pipes is sealed, except for the suction port and the leak position. Once a layer of air or atmospheric gas is established in the pipe near the leak position, inert gas is drawn from the pipe by the pump, in a direction toward an oxygen or atmospheric gas sensor. By doing this, the layer of air or atmospheric gas is moved along in the pipe from the leak position toward the oxygen sensor. A measurement is taken of the volume of gas being drawn while the layer of air or atmospheric gas is being moved along the pipe. The oxygen or atmospheric sensor indicates when the layer of air or atmospheric gas has arrived.Type: GrantFiled: September 24, 1986Date of Patent: November 10, 1987Assignee: Tokyo Gas Co. LimitedInventors: Akira Kawase, Minoru Imamura
