(54) ПЕРИФЕРИЧЕСКИЙ НАКАТ БУМАГОДЕЛАТЕЛЬНОЙ(54) PERIPHERAL PAPER HANDLING

II

Изобретение относ атс к конструкции бумагоделательной машины и можвт найти применение в целлюлозно-бумажной промышленности, а также в текстильной, . химической и полиграфической промышленности .The invention relates to the design of a paper machine and can be used in the pulp and paper industry, as well as in the textile industry. chemical and printing industries.

Известно устройство дл намотки бумажного полотна в рулон, содержащее хошгашр наката и передающее устройство с зубчатым колесом, расположенным эксцентрично относительно оилиндра у его торпа. Диаметр зубчатого колеса равен половине диаметра Оилиндра наката. Колесо закреплено неподвижно на оси, съ закной с трансмиссией и осью цилиндра. Ось колеса расположена вьпие оси шйшндра таким образом, что лишь небольша часть его окружности выступает над внешним краем цилиндра наката. Данный накат предназначен дл намотки бумажнезго полотна на тамбурный вал fl A device is known for winding a paper web into a roll comprising a host roll and a transmitting device with a gear wheel located eccentrically relative to the cylinder at its torp. The diameter of the gear is half the diameter of the overrun of the Oilindra. The wheel is fixed on the axle, with the transmission and the cylinder axis. The wheel axis is located above the axis of the shishndr in such a way that only a small part of its circumference protrudes above the outer edge of the overrun cylinder. This roll forward is intended for winding the paper-free cloth onto the fl y-chain shaft.

Поскольку при контакте тамбурного вала с цилиндром наката он непосредственно перекатываетс на поверхности циМАШИНЫSince, when the tambour shaft contacts the overrun cylinder, it directly rolls over the surface of the cytomachine.

линдра наката, то в момент разгона возникает проскальзьюание между контактирун цими поверхност ми. Проскальзывание между цилиндром наката и тамбурным валом приводит к ухудшению их поверхностей и повышению обрывности бумаз1шого полотна.Because Lindra Run, then at the time of acceleration, slippage occurs between the contacting surfaces. Slippage between the overrun cylinder and the tambour shaft leads to a deterioration of their surfaces and an increase in the breakage of the paper web.

iw,iw,

Известен также накат дл рулонного материала, содержащий хшлиндр, приводной диск, установленный по отношению к ЦИЛИНДРУ так, что его окружность выходит за пределы хшлиндра, трансмиссию между цилиндром и приводным диском, предназначенную дл передачи им одина15 ксжой скорости, тамбурный вал с держателем , дающим возможность тамбурному валу быть в соприкосновении с цилиндром или находитьс от него на рассто нии, устройство дл перемещени держател .Also known is a roll for a roll material containing an axle, a drive disk mounted with respect to the CYLINDER so that its circumference extends beyond the limits of the axle, a transmission between the cylinder and the actuator disk, designed to transfer them at an equal speed, a tambourine shaft with a holder enabling the shaft shaft is in contact with or located at a distance from the cylinder, a device for moving the holder.

Claims

The roll is intended for winding a paper web onto a tambour shaft and has a mechanism for accelerating the tambour shaft, which is designed to give the tambour shaft the same speed with a rolling roll 2. The FlenocTaTKOM of the device is that due to slippage in the transmission transmission, the speed of the tambour shaft is different from the speed of the roll cylinder, which leads to a break in the web at the time of refueling and an increase in the idling speed of the machine. Closest to the present invention is a roll-up, which contains a run-up cylinder with an annular groove on the surface of one of its ends, a tambour shaft and a device for its acceleration Gz. A disadvantage of the known device obryu linen due to the lack of synchronism of the speed of the chain shaft and the roll cylinder. The purpose of the invention is to reduce the breaks when filling the web. This goal is achieved by the fact that the cylinder of the peripheral roll of the paper machine, which contains the cylinder of the roll with an annular groove on the surface of one of its ends, a tambour shaft and a device for its acceleration, has an additional annular groove on the surface of its other end, and a device for acceleration of the chain shaft in the form of two elastic containers with a nipple for connection with a pressure source installed in annular grooves. FIG. Figure 1 shows the basic setup of a reel, side view; in fig. 2 - the same, top view; in fig. 3 - the position of the tambour shaft, the moment of contact with the ring elastic capacity; in fig. 4 is the same as the moment of contact with the overrun cylinder. The peripheral roll contains cylinder 1 reel with an annular groove 2 (groove) on the surface of one of. edges, chaining shaft 3 and a device for acceleration of the chained shaft. At the second edge of the cylinder, the overrun is additionally made with an annular groove 4. In both grooves, annular elastic vessels 5 are installed, which contact the surface of the tambour shaft 3. Under the overhang of the reel, the reel 3 is laid in its receiving levers, which is wound next to the reel to be wound. The axis of rotation of the take-up levers is eccentric relative to the axis of the cylinder 1 of overrun and the levers are initially arranged so that the tambour shaft 3 does not touch the cylinder of the overhang 1, but lies on the apastknye annular capacitance 5 (Fig. 3). The tambourine shaft 3 is pressed by its own body and power cylinders to the elastic annular containers 5. By the friction between the shaft 3 and the capacitances 4, the shaft 3 starts to rotate. Soon, the speeds of the overrun cylinder 1 and shaft 3 become equal, after which the take-up levers turn and the tambour shaft 3 begins to contact the overrun cylinder 1, compressing the elastic containers (Fig. 4). After this, the web is recharged to the chain shaft 3. The grinding in the elastic containers can be changed. When using a reel, complete synchronization of the rotation of the tambour shaft and the reel cylinder is achieved, which eliminates the breakage of the web and increases the reliability of the reel. The invention of the peripheral roll of the papermaking machine, comprising an overlap cylinder with an annular groove on the surface of one of its ends, a tambour shaft and a device for its acceleration, which is similar to an additional annular groove on the surface at the other end, and a device for accelerating the tambour shaft is made in the form of two elastic containers with a nipple for connection with a pressure source installed in annular grooves.
