Title: Starting point searching method for deburring robot
Inventor: NARISAWA KAORU
IPC: B24B27/00
Filed: 1987-02-25
Abstract: PURPOSE:To enable searching of correct starting point of machining, in a virtual compliance control deburring robot system, by employing a proper positioning device for approaching the macro position of a machining material sufficiently to an indicated referential locus. CONSTITUTION:A machining material 2 discharged from a machining device 1 is carried sequentially in the direction of an arrow by means of a carrying device 3 while being shifted by +e1 or -e2 in the direction Y with respect to a referential line A'. When the machining material 2 is fed to this stage, a pusher 4 projects to push the material 2 to the right until the material 2 contacts with a stopper 5 and a clamp 6 grips the material 2 at that position. The clamp 6 is interlocked with a double acting actuator 7 to pull back the material 2 to the left by a predetermined dimension so as to position the left end of the material 2 at an imaginary referential line BB' separated by predetermined distance l3 from a stopper 9 arranged don a deburring robot 8. When the material 2 comes to the position of the robots 8, 8', it is pushed by the stopper 9' of the robot 8' which is moved by a moving device 10 and positioned between the stoppers 9, 9'.

Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting a defective part of wood, e.g. a crack, shape, a knar, adhering resin, corrosion or discoloring, quickly and accurately. SOLUTION: Image of a wood 1 is picked up by means of a color CCD camera 5 and an image signal is compared with a reference color registered as the ground color of wood 1 by means of a color image extraction unit 6 and then it is subjected to binary processing and labeling in order to set an objective region to be measured. Image of the wood 1 is picked up by means of the color CCD camera 5 while illuminating the wood alternately from the left and right with two sets of light sources 2, 3. The image is binarized by means of an image processor 9 and the logical sum of binary images is determined to produce a synthesized image which is then subjected to labeling and compared with a decision value thus detecting a defective part, e.g. a crack, shape or knar.  Furthermore, the image of wood 1 is picked up by means of the color CCD camera 5 and the image signal is compared with the reference color of resin and discoloring by means of the color image extraction unit 6 and binarized. A binary image matching with an objective region is then subjected to labeling and compared with a decision value thus detecting a defective part, e.g. adhering resin, corrosion or discoloring.

Inventor: SUZUKI KOZO
IPC: G11B23/087
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To shorten the working time and to reduce the manufacturing cost by constituting the main body of the cartridge for housing an information recording medium by combining a pair of upper and lower halves, providing respective upper/lower halves with holes for force-fitting the coupling screw, and force-fitting coupling screws into the holes thereby coupling the upper and lower halves. SOLUTION: The tape cartridge 1 is furnished with the upper/lower halves 2, 3 in the rectangular shallow dish state, plural coupling screws 6 coupling these halves each other, and screw holes 7 for force-fitting the coupling screws. By forming the coupling screws 6 by e.g. high hardness rubber material such as a polysulfide rubber, etc., or resin material such as an elastic plastic, etc., the damage of the screw holes 7 at the time of force-fitting to the screw holes 7 is prevented to attain the increase of the coupling reliability. Also, restraining parts, the hole diameters of which are smaller than those of the coupling screws 6, are formed on the screw holes 7.  So, when the coupling screws 6 are force-fitted into the screw holes 7, tip parts of the coupling screws 6 are restrained to the formed restraining parts so that the upper and lower halves 2, 3 are fixable in the coupling state. Meanwhile, the force-fitting operation is carried out by a force-fitting hammer, etc., of a screw force-fitting device.

Abstract: PURPOSE:To prevent the fastening force from being loosened when vibration is applied by arranging a roller looking the one-way rotation of a ring to a shaft and a groove in parallel with a shaft and bringing the ring into contact with the roller on one end side of the axial movement. CONSTITUTION:When a ring 2 is rotated in the arrow F direction, the ring 2 and a shaft 2 are disengaged because a groove 40 has a wedge-shaped cross section, a taper bush 25, a guide block 7 and a float screw 6 are rotated, a claw 5 is advanced to fasten a tool. If the shaft 1 is rotated in the arrow T1 direction when the tool is fastened with a screw, the relative rotation in the arrow F direction fastening the tool occurs on the ring 2. When it is to be loosened, the shaft 1 is rotated in the arrow T2 direction, a needle roller 9 bites into the groove 40, the ring 2 is locked. When axial vibration is applied at this time, the ring 2 and the needle roller 9 are parallel with the shaft 1 and no axial component force is generated, the lock is not released. To remove the tool, the ring 2 is retreated, a lock metal 23 is separated from the needle roller 9 and rotated in the arrow U direction to spread a claw 5.
