Description

Изобретение относитс к печатным листовым машинам, примен емым в полиграфической промышленности и предназначетс дл автоматического отделени листов от стопы бумаги и подачи их по одному в печатный аппарат.The invention relates to printing sheet machines used in the printing industry and is intended to automatically separate sheets from a stack of paper and feed them one by one to a printing machine.

Известен электростатический самонаклад содержаший установленные на станине стапельный стол, отдел юш,ий механизм с электродами , листовыводной механизм, зар дник и привод 1.The electrostatic feeder is known, which contains a slip table installed on the bed, a separate section with an electrode, a leaflet mechanism, a charging unit, and a drive 1.

Недостатком известного самонаклада вл етс невысока производительность и мала надежность отделени листов по одному особенно тонких сортов бумаги, а также большие габариты самонаклада.A disadvantage of the known sheet feeder is the low productivity and low reliability of separating sheets of especially thin paper grades one by one, as well as large dimensions of the sheet feeder.

Цель изобретени - повышение надежности и снижение габаритов самонаклада.The purpose of the invention is to increase the reliability and reduce the size of the feeder.

Указанна цель достигаетс тем, что от .ло.л юший механизм имеет установленный на станине корпус и смонтированные в нем втулки, причем одни из них закреплены жестко, а другие св заны с приводом, при этом дисковые электроды установлены на неподвижных втулках, а остальные выполнены в виде секторов, расположенных по рабочему периметру каждой приводной втулки .This goal is achieved by the fact that from this looser mechanism has a body mounted on the frame and sleeves mounted in it, some of which are rigidly fixed and others connected to the drive, while the disk electrodes are mounted on fixed sleeves and the rest are in the form of sectors located on the working perimeter of each drive sleeve.

Корпус и втулки выполнены из диэлектрического материала.The housing and bushings are made of dielectric material.

Привод представл ет собой зубчатый механизм .The drive is a gear mechanism.

На фиг. 1 представлена кинематическа схема электростатического самонаклада; на фиг. 2 - привод самонаклада и его основных узлов; на фиг. 3 - пластины-электроды; на фиг. 4 - конструкци токосъемников; на фиг. 5 -- р;13рез А-А на фиг. 2.FIG. Figure 1 shows the kinematic scheme of an electrostatic charge pump; in fig. 2 - drive of the feeder and its main components; in fig. 3 - plate electrodes; in fig. 4 - design of current collectors; in fig. 5 - p; 13resA-A in FIG. 2

Электростатический самонаклад состоит из стапельного стола со стопой листов 1, электродов 2, неподвижных диэлектрических втулок 3 с дисковыми электрода.ми 4, подвижных диэлектрических втулок 5, токосъемников 6 и 7, диэлектрической плиты 8, диэлектрического корпуса 9, листовыводной пары 10 и 11 и привода самонаклада с группой зубчатых колес.Electrostatic samonaklada consists of a bed table with a foot of sheets 1, electrodes 2, stationary dielectric bushings 3 with disk electrodes. 4, movable dielectric bushings 5, current collectors 6 and 7, dielectric plate 8, dielectric body 9, leaflet pair 10 and 11 and drive feeder with a group of gears.

Электростатический самонаклад работает следующим образом.Electrostatic feeder works as follows.

Claims

The top sheet is separated from the foot 1 with help: and the impact on it of a vortex electrostatic field arising between rotating charged electrodes 2 fixed on dielectric bushings 5 and fixed disk electrodes 4 rigidly mounted on dielectric bushings 3, which are all mounted together dielectric housing 9. To simplify reading of the drawing, FIG. 5 does not show a constructive fastening of the current collectors 6 and 7, the structures of which are shown in FIG. 4, supplying voltage through contacts (+) to periodically arranged circumferentially electrodes 2 mounted on rotating dielectric sleeves 5. To eliminate contact of a separate sheet with rotating sleeves 5 and electrodes 2, it is pressed by a vortex electric field to a fixed dielectric plate 8 and when the voltage is removed from the current collectors 6, which is supplied only to the current collectors 7, it is transmitted to the sheet-feeding pair 10 and 11. The drive of the feeder and its main mechanisms are driven through gears71, Zz 2 s, sa, zs, ze, zy, zs (see 1 and 2). The use of the proposed feeder will reduce the effective production area of the printing shop. Claim 1. Electrostatic samonaklad containing a stacking table installed on the bed, separating mechanism with electrodes, one of which is made in the form of discs, sheet-cutting mechanism, charger and actuator, characterized in that in order to increase reliability and reduce samonaclada dimensions the department The mechanism has a case mounted on the frame and mounted bushes in it, some of which are rigidly fixed, while others are connected to the drive, while the disk electrodes are mounted on the stationary bushings and the rest nye made in the form of sectors arranged on the working perimeter of each drive sleeve.

2. Samonaclad according to claim 1, characterized in that the housing and the bushings are made of a dielectric material.

3. Samonaklad under item 1, characterized in that the drive is a gear mechanism. Information sources. taken into account during the examination 1. USSR copyright certificate for application No. 2559829/12, 1977.
