| 20090214313 | MACHINING UNIT AND MACHINE TOOL - A machining unit that is supported on a machine tool and machines a workpiece by a revolving tool with a main spindle section being driven and rotated includes an eccentric rotational section, a tool holder, a tool revolution-radius changing mechanism, and a cutting-edge-orientation correcting mechanism. The eccentric rotational section is disposed on the main spindle section, and is rotatable about an eccentric axis that is located eccentrically at any distance in a radial direction of the main spindle section from a rotation center of the main spindle section. The tool holder is disposed on the eccentric rotational section, and supports the tool. The tool revolution-radius changing mechanism moves the tool in the radial direction, and changes the radius of the revolution of the tool by rotating the eccentric rotational section about the eccentric axis. The cutting-edge-orientation correcting mechanism corrects the orientation of a cutting edge of the tool by making the tool holder spin about an axis of the tool holder, the axis being parallel to the rotation center of the main spindle section. | 08-27-2009 |
| 20090120989 | MATERIAL FEEDING APPARATUS - A material feeding apparatus has a vibration absorbing construction, in which an impulse and vibrations from a press apparatus, etc. are hard to transmit to a material feeding equipment, etc., and includes an inner housing that accommodates therein the material feeding equipment, and an outer housing connected to the inner housing through a vibration absorbing member. A vibration restricting member is provided between the housings to restrict the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member when an impulse force acts on the outer housing, only in a vertical direction. The vibration restricting member includes an upper plate member, upper and lower surfaces of which are interposed between a top wall of the outer housing and a top wall of the inner housing, and a lower plate member, upper and lower surfaces of which are interposed between a bottom wall of the outer housing and a bottom wall of the inner housing. | 05-14-2009 |
| 20090108522 | SHEET MATERIAL FEEDING APPARATUS - A main roll and a sub-roll of a sheet material feeding apparatus interpose therebetween a sheet material to intermittently feed the same to a press apparatus. A roll clearance is adjusted according to a sheet thickness by displacing the main roll up and down. A release device that temporarily releases a sheet material having been interposed by the both rolls just before the sheet material is subjected to press working by the press apparatus includes a sub-roll guide that can move up and down together with the sub-roll, a rectilinear cam, and cam followers for engagement with a cam surface of the rectilinear cam, and the release device moves the rectilinear cam axially of the sub-roll in synchronism with the operation of the press apparatus to thereby displace the sub-roll up and down through the cam followers and the sub-roll guide. | 04-30-2009 |
| 20090108521 | SHEET MATERIAL FEEDING APPARATUS - A sheet material feeding apparatus capable of favorably guiding a sheet material to perform smooth feeding comprises a pair of rolls and first and second guide members and permits a sheet material to pass between the first guide member and the second guide member. One of the rolls has a plurality of circumferential grooves arranged between both ends of a sheet material feeding surface in an axial direction and spaced from one another in the axial direction, and the first guide member includes guide portions passing through the respective circumferential grooves and extending continuously to a downstream side from an upstream side between the pair of rolls in a sheet-material conveyance direction. | 04-30-2009 |
| 20080296126 | PRODUCT TRANSPORT APPARATUS - A product transport apparatus is provided that includes a transport section for transporting a product by oscillating; a driving section for applying oscillations to the transport section; a product supply section for storing products therein, the product supply section having an aperture for supplying the stored products to the transport section; and a supply stop section that can stop the supply of the products from the aperture by being brought close to the aperture, wherein, when the products are supplied from the product supply section to the transport section, the supply stop section moves away from the aperture and the supply stop section causes at least some of the products on the supply stop section to move toward the transport section by oscillating. | 12-04-2008 |
