Изобретение относитс к блокообрабатывающему оборудованию, примен емому в брошюровочно-переплетных процессах.BACKGROUND OF THE INVENTION The invention relates to block-processing equipment used in binding and binding processes.
Известны устройства дл приклеивани к книжному блоку корешкового материала, разматываемого из рулона вдоль движени блока , содержащие механизмы подачи, отрезки и приклейки. В этих устройствах лента материала разматываетс и подаетс в результате движени блоков, к которым материал приклеиваетс . При этом лента движетс сплошной полосой, заполн интервалы между блоками.Arrangements are known for gluing a radicular material unwound from a roll along the movement of the block to the book block, which include feeding mechanisms, lengths and gluing. In these devices, the tape of material is unwound and fed as a result of the movement of the blocks to which the material is glued. In this case, the tape moves with a continuous strip, filling the intervals between the blocks.
При использовании таких устройств увеличиваетс расход корешкового материала из-за заполнени интервалов между блоками, и в них не прекраш,аетс подача материала при неподаче одного или нескольких блоков подр д. Кроме того, известные устройства не обеспечивают возможности приклейки материала не по всей длине корешка, а лишь на части длины или с определенным отступом от торцов блока.When such devices are used, the consumption of the spine material increases due to the filling of the intervals between the blocks, and the supply of material does not stop there when one or several blocks are not supplied. Besides, the known devices do not provide the possibility of sticking the material but only part of the length or with a certain indent from the ends of the block.
Целью изобретени вл етс повышение технологических возможностей устройства. Дл этого механизм подачи материала выполнен в виде двух пар валиков, расположенных по разные стороны от механизма отрезки. При этом перва пара, расположенна между механизмом приклейки и механизмом отрезки , непрерывно вращаетс в направлении подачи материала, а втора - кинематически св зана с приводом дл периодического поворота нижнего валика.The aim of the invention is to increase the technological capabilities of the device. For this, the material feed mechanism is made in the form of two pairs of rollers located on opposite sides of the segment mechanism. In this case, the first pair, located between the gluing mechanism and the cutting mechanism, rotates continuously in the material feed direction, and the second is kinematically connected with the drive for periodic rotation of the lower roller.
На чертеже схематично изображено предлагаемое устройство.The drawing schematically shows the proposed device.
Устройство состоит из механизма подачи материала, содержащего рулон 1, стол 2 и валики 3, 4; механизма отрезки с ножами 5,The device consists of a material feed mechanism comprising a roll 1, a table 2 and rollers 3, 4; Mechanism cuts with knives 5,
6 и механизма проводки с валиками 7, 8. При этом привод нижнего валика 4 состоит из кулака 9, двуплечего рычага 10, зубчатой пары 11, 12 и обгонной муфты 13. Привод ножа 6 осуществл етс кулаком 14 через рычаг 15.6 and the wiring mechanism with rollers 7, 8. In this case, the drive of the lower roller 4 consists of a cam 9, a two-armed lever 10, a gear pair 11, 12, and an overrunning clutch 13. The knife 6 is driven by the cam 14 through the lever 15.
Устройство работает следующим образом. Материал с рулона 1 по столику 2 проходит через периодически поворачивающиес валики 3, 4, ножи 5, 6 и вращающиес с иосто нной скоростью валики 7, 8. После отрезки лента не движетс до тех пор, пока не повернетс валик 3, приводимый от кулака 9 через двуплечий рычаг 10, зубчатую пару 11, 12 и обгонную муфту 3. Поворот валика и,The device works as follows. The material from roll 1 through table 2 passes through periodically rotating rollers 3, 4, knives 5, 6 and rollers 7, 8 rotating at iostoy speed. After cutting, the tape does not move until roller 3, driven from fist 9 through two shoulders lever 10, a gear pair 11, 12 and an overrunning clutch 3. Rotate the roller and,
следовательно, величина подачи материала посто нны и равны приблизительно рассто нию от линии реза до линии контакта вращающихс валиков 7, 8. Нож 5 неподвижен, а нож 6 приводитс от кулака 14 через двуплечий рычаг 15. Отрезанна полоска, двига сь далее, прижимаетс валиком 16 к блоку . Затем цикл повтор етс .Consequently, the material feed rate is constant and approximately equal to the distance from the cutting line to the contact line of rotating rollers 7, 8. Knife 5 is stationary, and knife 6 is driven from cam 14 through double-arm lever 15. The cut strip moves further, pressed by roller 16 to block. Then the cycle is repeated.
Дл обеспечени плавного разгона рулона 1 с целью снижени динамических нагрузок и повышени точности отрезаемой полоски разгон валиков 3, 4 производитс по заданному закону, определ емому профилем кулака 9.In order to ensure smooth acceleration of the roll 1 in order to reduce dynamic loads and improve the accuracy of the cut strip, the acceleration of the rollers 3, 4 is carried out according to a predetermined law determined by the profile of the cam 9.
