  • Patent number: 9079275
    Abstract: An automatic screw tightening apparatus suppresses damage of an inner wall of a transfer tube, stabilizes the posture of the screw, stably supplies the screw to a driver bit, and reduces screw tightening time. A rotatable arm is installed at the screw discharging unit and a feed head unit is installed at a fore end of the rotatable arm to be brought into close contact with a driver bit portion of a fore end of the screw tightening mechanism. The feed head unit is movable between close contact with the driver bit portion and an evacuation position where the feed head unit is far from the driver bit unit. At the close contact position, the driver bit portion of the fore end of the screw tightening mechanism is brought into contact with the screw and sucks a head portion of the screw to engage the screw.

  • Patent number: 8191731
    Abstract: The present invention provides an apparatus for feeding screws. In the apparatus, screws are scooped up from the storage container by a scooping unit and put onto a carrying unit. The screws are arranged in line and carried by the carrying unit and discharged through a discharge unit. The scooping unit includes a rotating arm which rotates on the outer wall of the storage container, and a magnet which is fastened to the front end of the rotating arm. The carrying unit includes a screw receiving part. The rotating arm rotates on the outer wall of the storage container to scoop up the screws using magnetic force of the magnet and load the screws onto the screw receiving part. The scooping unit further includes a magnet spacing part which is provided on the outer wall of the storage container.

  • Patent number: 7022051
    Abstract: Even if the tension of the endless belt against the sliding contact member is reduced, the slip of the endless belt out of the rotary roller is prevented and the endless belt is smoothly moved. Also, since frictional resistance of the endless belt against the sliding contact member is reduced, durability of the endless belt can be substantially improved. The present running machine comprises a rotary roller 23 for circulatingly move an endless belt 20 mounted to the bedplate 10 and supported at a supporting plate 22 by a driving unit 26, a sliding contact member 25 for guiding the sliding-contact movement of the endless belt 20, a tension roller 30 for depressing the upper portion of the endless belt toward the lower portion, thereby making a distance of the upper portion and the lower portion smaller than the diameter of the rotary roller 23, and a tension/contact roller 40 depressing and contacting the endless belt 20 to the rotary roller 23.

  • Patent number: 6607469
    Abstract: A running machine having a.reduced height from the ground to a running surface on an endless belt without decreasing the outside diameter of a driving roller. The running machine includes a driving roller for rotating the endless belt mounted in an inner portion of a frontal end of the endless belt, and a tension member mounted near the driving roller, depressing the upper portion of the endless belt toward a lower portion thereof to maintain a tensioned state of the endless belt. Thus, the distance between the upper portion and the lower portion of the endless belt is made smaller than the diameter of the driving roller.
