摘要： In a planographic printing plate feeding apparatus, a load W applied to a stack of plates by a pickup roller which feeds a planographic printing plate from the stack is adjusted. If the load W is increased and exceeds a single feeding threshold, and if a conveyance force F1 applied from the uppermost planographic printing plate to the slip-sheet is increased by such a degree that the conveyance force F1 exceeds a maximum static friction force F2′ between the slip-sheet and the planographic printing plate under the slip-sheet, the uppermost planographic printing plate and the slip-sheet 22 can be conveyed integrally (set feeding). Hence, it is possible to obtain a planographic printing plate feeding apparatus with a compact, simple and inexpensive structure and able to feed a planographic printing plate swiftly and reliably.

摘要： A pair of optical sensors are disposed above photopolymer plates and interleaf papers, which are alternately stacked with one another. These optical sensors basically have the same structure. However, the optical sensor is disposed so as to be inclined to an optical axis of reflected light, and therefore, a detection level of the optical sensor substantially becomes low. Accordingly, although the optical sensors each react to the reflected light from the photopolymer plate, the optical sensor does not react to the reflected light from the interleaf paper. As a result, it is determined whether the uppermost layer of the stack is the photopolymer plate or the interleaf paper. In a discriminating device of the present invention, general purpose optical sensors adapted to react to light having such a fixed intensity or greater, are used.

摘要： A receiving guide is attached to an upper portion of a discharge mechanism section via a bracket. When a photopolymer plate is discharged from a photopolymer plate conveying section, a leading end portion of the photopolymer plate, which is in a state of hanging down slightly, abuts a flat plate portion of the receiving guide. Thereafter, the receiving guide moves in accordance with movement of the leading end portion of the photopolymer plate. Further, the receiving guide moves forward in a conveying direction of the photopolymer plate immediately before conveying of the photopolymer plate is completed, and the photopolymer plate lands on the surface plate.

摘要： A casing of a ball bearing which holds a ball screw can be displaced on a supporting stand against urging force of a compression coil spring and a tensile coil spring. If vibration of the ball screw is transmitted to the casing, the casing attempts to move on the supporting stand. However, when, due to the vibration, the casing is displaced against the urging force of the compression coil spring and the tensile coil spring, the urging force forcibly attempts to return the casing to its original position. A frequency of vibration of the casing is thereby forcibly changed.

摘要： A discrimination device which is disposed on a conveyance path of conveyed items, such as planographic printing plates, slip sheets and the like. The discrimination device is structured with a first sensor, which detects presence or absence of the conveyed items, and second and third sensors, which identify types of the conveyed items. The first sensor can judge presence or absence of a conveyed item from whether or not irradiated light is reflected by a conveyed item. The second and third sensors discriminate between the types—the planographic printing plates and the slip sheets—by the intensity of reflected light, on the basis of a difference in surface reflectivities of the conveyed items. With these three optical sensors, it is possible to reliably identify four conveyance configurations of the conveyed items.

摘要： A printing plate sucker capable of stably suction-adhering and sheet-feeding both a printing plate and a protective sheet simultaneously without causing wrinkling at the protective sheet during the suction-adherence and sheet-feeding. The sucker is structured by a main body portion formed of a stiff body, a skirt portion formed of a resilient body, and a spring. When a moment from a printing plate acts on the sucker during sheet-feeding, the spring resiliently deforms. Thus, the main body portion is displaced (inclined) in the moment application direction, effective weight on the sucker is reduced, and a state in which a reduced moment acts on the sucker is achieved (the moment is substantially absorbed). Furthermore, the spring which redirects the moment is structured separately from the main body portion and skirt portion. Therefore, the sucker will not be deformed, an interleaf sheet will not be hoistingly deformed, and wrinkling will not occur.
摘要翻译： 一种印版吸盘，能够在吸附粘合和片材供给期间同时稳定地吸附粘合和片材供给印刷版和保护片而不会在保护片上产生褶皱。 吸盘由由刚体形成的主体部分，由弹性体形成的裙部和弹簧构成。 当在片材进给期间来自印版的片刻作用在吸盘上时，弹簧弹性变形。 因此，主体部分在力矩施加方向上移位（倾斜），减小了吸盘上的有效重量，并且实现了减小的力矩作用在吸盘上的状态（该力矩基本上被吸收）。 此外，重新定向的弹簧与主体部分和裙部分离开地构成。 因此，吸盘不会发生变形，中间板不会变形，不会起皱。
