20080296829 | SHEET TAKEOUT DEVICE - A sheet takeout mechanism has a takeout roller that rotates in contact with a sheet located at a takeout position, and a motor that intermittently rotates the takeout roller. A triangular suction port is formed on a suction surface of the takeout roller and has a vertex located downstream in a rotation direction of the takeout roller. When a negative pressure is exerted on the sheet via the suction port, the suction force is weak at the beginning of suction and then increases gradually. | 12-04-2008 |
20080315512 | SHEET PROCESSING DEVICE - A posture control device has a posture detecting section, an upstream conveying section, a posture control section, and a downstream conveying section along a conveying path for mail items. The distance from a nip of the upstream conveying section and a nip of the posture control section (D-E distance) is designed to be substantially as long as the longest one of the mail items to be processed by the device which has the greatest length along a conveying direction. The distance from the nip of the posture control section and a nip of the downstream conveying section (E-F distance) is designed to be slightly longer the shortest one of the mail items to be processed by the device which has the shortest length along the conveying direction. | 12-25-2008 |
20100270730 | PAPER SHEET PICKUP DEVICE - A paper sheet pickup device includes a pickup belt configured to run along one of accumulated paper sheets, which is positioned at the most downstream side with respect to a direction of accumulation, and a negative pressure chamber provided inside the pickup belt. The negative pressure chamber is connected to a pump, and a valve unit is interposed therebetween. Further, an air inlet tube is connected to the negative pressure chamber for supplying air therein. | 10-28-2010 |
20110031683 | SHEET MASS MEASURING UNIT - A mass measuring unit includes two driving rollers vertically separate from each other and intersecting the direction of conveyance of a mail matter. Servo motors for driving the driving rollers are connected to torque detection units. A control unit controls motor control units to cause them to impart a rate difference between the driving rollers to rotate the mail matter during its conveyance, and to cause the torque detection units to detect the torque values of the servo motors. The control unit compares the thus detected torque values with the torque values of the servo motors detected when the servo motors are idling without rotating the mail matter, thereby measuring the mass of the mail matter using a calculation unit. | 02-10-2011 |
20110042886 | VALUE DEVICE AND PAPER SHEET PICKUP APPARATUS - A valve device is provided with a first block connected to an upstream-side suction tube that is connected to a negative-pressure chamber, a second block connected to a downstream-side suction tube that is connected to a pump, first and second shielding plates rotatably interposed between the first and second blocks, and servo motors for rotating the shielding plates. Each of the shielding plates has a plurality of air passing holes, and are rotated in opposite directions. | 02-24-2011 |
20110254220 | SHEET HANDLING APPARATUS - According to one embodiment, a pickup device includes a separation mechanism for applying, to a to-be-subsequently-fed mail item picked up from accumulated mail items, a separation force exerting in a direction opposite to a mail item pickup direction. The separation mechanism comprises an outer drum with suction holes that face the to-be-subsequently-fed mail item during rotation, an inner drum provided inside and concentric with the outer drum and having air holes that overlap with the suction holes during rotation, a pump for drawing air through the suction holes facing the to-be-subsequently-fed mail item and the air holes overlapping with them to attach the to-be-subsequently-fed mail item to the outer peripheral surface of the outer drum. A controller rotates the inner and outer drums in association with each other to apply a sufficient separation force to the to-be-subsequently-fed mail item. | 10-20-2011 |
20120160574 | VEHICLE PASSAGE TREAD SENSOR AND VEHICLE PASSAGE DETECTION APPARATUS - According to one embodiment, a vehicle passage tread sensor buried in a road in a direction substantially perpendicular to a traveling direction of a vehicle, includes a pipe including a cavity inside and formed of an elastic material, a fluid filling the cavity of the pipe, and a fluid pressure sensor configured to measure a pressure of the fluid. | 06-28-2012 |
20150239015 | GOODS SORTING APPARATUS - According to one embodiment, a goods sorting apparatus includes: conveyor units configured to move in a conveying direction of goods and transfer the goods loaded thereon in a direction intersecting the conveying direction; a sorting portion configured to sort the goods conveyed by the conveyor units; a first conveyor route along which the conveyor units move toward the sorting portion at a first speed; a loading portion in which the goods are loaded onto the conveyor units at a loading position; a second conveyor route having a decelerating area in which the conveyor units decelerate toward a second speed, which is lower than the first speed, on the upstream side in the conveying direction of the loading position, a movement area in which the conveyor units move at the second speed at the loading position, and an accelerating area in which the conveyor units accelerate toward a speed higher than the second speed, on the downstream side in the conveying direction of the loading position; and a conveyor route switching portion at which the goods are conveyed from the second conveyor route to the first conveyor route. | 08-27-2015 |
