Abstract: A separating device readily separates a desired number of sheets of paper in bundle form from a pile of paper sheets placed on a pallet or skid without disturbing the orderly piled-up bundle. The device comprises a nozzle made in a flat, palmlike form by which a compressed air is ejected into the boundary portion between the paper bundle and the paper pile and diffused uniformly over the entire area of the boundary portion to provide an air separation layer. The nozzle has guides for effecting diffusion of the compressed air.

Abstract: An apparatus to be used in transferring a bundle of paper from a paper pile on a table lifter or the like onto a table in the subsequent step. Upon detecting undulation in the top surface of the paper pile, a suitable number of detectors emit a signal indicating whether the paper bundle can be transferred or not to control the upward movement of the paper pile. Before transference, the end of the undulated paper bundle is flattened by an intermediate unit and clamped by a clamp device.

Abstract: For the transfer of a bundle of paper, the end of the paper bundle is grasped and drawn by a clamp device. By utilizing the flexibility of the paper bundle, clamping pressure required is made as low as possible so as to protect the end portion of the bundle. A lower clamp seat for contact with the lowermost surface of the paper bundle is inclined downward toward the end of the paper bundle, while a pressing portion of an upper clamp seat for pressing the upper surface of the bundle is positioned closer to the end of the bundle than the highest portion of the lower clamp seat.

Abstract: A guide device for a long object includes a belt-shaped unit. The belt-shaped unit includes a first tubular member and a second tubular member. The first tubular member accommodates an elongated support member. The second tubular member accommodates a long object having flexibility. The second tubular member is shorter than the first tubular member. At least at one end of the belt-shaped unit, the first tubular member and the second tubular member are integrated with one another into the belt shape in a state in which an end of the first tubular member extends farther than an end of the second tubular member in a lengthwise direction of the belt-shaped unit.

Abstract: An engagement chain includes a pair of first and second chain members that are engaged so as to be integrated with each other by moving in an advancing direction and disengaged from each other so as to bifurcate by moving in a retreating direction from the integrated engaged state. A first link plate of the first chain member includes first and second pin holes through which a coupling pin is inserted. A second link plate of the second chain member includes first and second pin holes through which a coupling pin is inserted. A first distance between the first and second pin holes of the first link plate is shorter than a second distance between the first and second pin holes of the second link plate.

Abstract: An object of the present invention is to provide a sprocket that mitigates the impact of tension fluctuations resulting from load torque changes, suppresses noise and vibration, ensures stable chain behavior, prevents sprocket durability loss and the generation of harmonics during rotation, along with a chain drive system. Tooth roots between adjacent teeth of the sprocket include those with a radial deviation from a root circle of a standard tooth profile, set within a predetermined numerical range corresponding to a tooth pitch. A phase variation pattern is created by changing a root radius in accordance with an angular position. The phase variation pattern has a waveform with an amplitude varied within a range of (1/7)Amax, where Amax represents a maximum amplitude. The chain drive system includes a plurality of sprockets and a chain passed over the sprockets, at least one of them being the above-described sprocket.

Abstract: To provide a cam clutch unit that is easy to handle before assembly, with its components prevented from lifting or detachment, and that allows production with fewer machining steps and a lower level of difficulty, while also enabling unit thickness reduction. The cam clutch unit of the present invention includes: a plurality of cams arranged between an inner race and an outer race; a cage ring having a plurality of pocket portions that restrict relative circumferential movements of the cams; and an annular spring that biases the cams. The cams have an engagement step adapted to engage with the spring on one axial end face. The cage ring has a plurality of hook portions that restrict an axial movement of the annular spring. The hook portions have a pressing part that allows the spring to press the cams towards the other axial end.
