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。

摘要： In a sheet sucking/feeding device, actuators are independently and individually connected respectively to plural suction cups. At a point in time when a printing plate is sucked and raised up by a predetermined amount, every other one of the actuators is simultaneously operated such that the suction cups connected to the operated actuators are displaced upwardly. The sucked uppermost printing plate is curved so as to become wavy. Air enters in between the uppermost printing plate and a next printing plate therebeneath such that that printing plate therebeneath is disjoined (separated). Only the uppermost printing plate is stably removed and fed out.

摘要： In a sheet sucking/removing device, suction cups are controlled to a state of a first negative pressure which is a minimum pressure needed to suck and remove only one uppermost printing plate, and sucking/removing is carried out. Thereafter, the suction cups are controlled to a state of a second negative pressure which is needed for conveying and supplying the printing plate, and conveying/supplying of the printing plate is carried out.

摘要： A guide member is provided at a downstream side of a stack of plates in a direction in which a planographic printing plate is conveyed. The guide member abuts a leading edge of an uppermost planographic printing plate to be conveyed, and bends the planographic printing plate, and further, permits the uppermost planographic printing plate and an interleaf paper adhering thereto in such a manner as to be inclined by being pressed by the planographic printing plate.

摘要： A protective sheet peeling device which reliably separates, from a sheet, a protective sheet (an interleaf sheet) which is superposed with one surface of the sheet. A free roller is disposed at a downstream side of a conveying roller of a peeling section, in a state in which one portion of the free roller is disposed on an “imaginary conveying locus” of a printing plate precursor. Further, a displacement roller is disposed at a downstream side of the free roller. After the printing plate precursor, which is superposed with the interleaf sheet, has passed by the free roller, when the displacement roller moves to a position of reaching the “imaginary conveying locus”, the printing plate precursor and the interleaf sheet are curved along the free roller. Due to reverse rotation of the displacement roller, the interleaf sheet is peeled off of the printing plate precursor.

摘要： In a removing/conveying portion of a printing plate removing/supplying device, when one cassette among a plurality of cassettes is empty, the empty cassette is placed on a raising/lowering stand and moved to a loading space. Due to a spur gear being rotated clockwise by a motor, a sliding cover, with which the spur gear is engaging, is moved toward a removing portion such that an opening of a cassette stocker portion is opened. In this way, it is possible to refill and load printing plates from a top side of the cassette stocker portion into the empty cassette positioned at the loading space.

摘要： A sheet material stacking device and an automatic exposure device for a printing plate, capable of stacking a number of interleaf sheets stably and efficiently. A pair of skewered rollers are provided at the sheet material stacking device used for the automatic exposure device. An interleaf sheet, which is fed from an interleaf sheet transport section, is guided by guide plates and nipped by the rollers. The interleaf sheet, while maintaining a so-called stronger pulling tension, is forcibly fed to an interleaf sheet accommodating section and stacked. Even if the interleaf sheet is thin, the interleaf sheet can behave stably as it is being stacked, and a number of the interleaf sheets can be stacked regularly and effectively.

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.
