Description

Известно устройство дл  продольной разрезки оттисков, например, на двухоборотных плоскопечатных машинах, выполненное в виде пары взаимодействующих друг с другом дисковых ножей, причем нижний из них установлен на ведущем валу выводного транспортера машины, несущем ведущие металлические ролики.A device for the longitudinal cutting of impressions, for example, on two-turn flat-bed printing machines, is made in the form of a pair of circular knives interacting with each other, and the lower one is mounted on the drive shaft of the exit conveyor of the machine carrying the leading metal rollers.

Предлагаемое устройство, по сравнению с известным, улучщает разрезку оттисков и устран ет возможность разрезки при выключенном натиске печатного цилиндра, что устран ет норчу оттиска. The proposed device, in comparison with the known, improves the cutting of prints and eliminates the possibility of cutting when the onset of the printing cylinder is off, which eliminates the imprint of the print.

Особенность устройства заключаетс  Б том, что верхний нож установлен на валу, получающем движение от ведущего вала с помощью зубчатой передачи.A feature of the device is that the upper knife is mounted on a shaft that receives movement from the drive shaft by means of a gear.

Один из металлических ведущих роликов выполнен конусным.One of the metal drive rollers is tapered.

Вал, несущий верхний нож, подпружинен в осевом направлении и снабжен кольцевым упором, взаимодействующим с роликом двуплечего рычага, приводимого в движение системой т г от рычага, закрепленного на валу выключени  натиска .The shaft carrying the upper knife is spring-loaded in the axial direction and provided with an annular stop interacting with a roller of the two shoulders of the lever, driven by a system of t from the lever fixed on the on-off shaft.

На фиг. 1 изображена схема устройства; на фиг. 2-вид по АА на фиг. 1; на фиг. 3-вид по стрелке Б на фиг.-2; на фиг. 4-вид по стрелке В на фиг. 1.FIG. 1 shows a diagram of the device; in fig. 2 is a view of AA in FIG. one; in fig. 3 is a view along arrow B in FIG. -2; in fig. 4 is a view along arrow B in FIG. one.

Дисковые ножи / и 2 и ведущие ролики предназначены дл  продольной разрезки оттисков носле печати и дальнейшей транспортировки их на выводную каретку двухоборотной плоскопечатной машины.The circular knives / and 2 and the drive rollers are intended for the longitudinal cutting of impressions during printing and further transporting them to the discharge carriage of a double-turn flat-bed printing machine.

Верхний дисковый нож 1 и два ведущих обрезиненных ролика 3 иTop disk knife 1 and two leading rubberized rollers 3 and

4установлены на валу 5, получающем вращение от ведущего вала 6 посредством пары шестерен 7 и 8.4 installed on the shaft 5, receiving rotation from the drive shaft 6 by means of a pair of gears 7 and 8.

На ведущем валу 6 (первого выводного транспортера) закреплен нижний дисковый нож 2 и металлические ведущие ролики 9 и 10.On the drive shaft 6 (the first outlet conveyor) is fixed the lower disk knife 2 and the metal drive rollers 9 and 10.

Дл  обеспечени  посто нного соприкосновени  ножей и 2 на валуTo ensure constant contact of the knives and 2 on the shaft

5установлена пружина 11. Дисковые ножи 1 2 заточены с5 installed spring 11. Circular knives 1 2 sharpened with

торца под некоторым, углом, что обеспечивает их самозаточку.butt end at a certain angle, which ensures their sharpening.

3. Устройство пп. 1 и 2, отличающеес  тем, что, с целью автоматического выключени  устройства при выключении натиска, вал, несущий верхний нож, подпружинен в осевом направлении и снабжен кольцевым упором, взаимодействующим с роликом двуплечею рычага, приводимого в движение системой т г от рычага, закрепленноГхО на валу выключени  натиска.3. Device nn. 1 and 2, characterized in that, in order to automatically turn off the device when the onset is turned off, the shaft carrying the upper knife is spring-loaded in the axial direction and provided with an annular stop interacting with the roller by the two shoulders of the lever, set in motion by a system of t from the lever fixed on on-off shutdown shaft.
