ROLLING SHAFT HANTERING AV RULLNINGSAXLAR

FIELD OF THE INVENTION

The invention relates to the treatment of winding shafts. In particular, but not exclusively, the invention relates to the treatment of winding shafts and machine reels at the finishing end of a fiber web machine.

BACKGROUND OF THE INVENTION

In papermaking lines, papermaking is a continuous process. A paper web made from a paper machine is rolled around a reel axis, a reel spool, into a machine roll, which can be over 5 meters in diameter and weighs more than 160 tons. The purpose of the winding is to convert a flat paper web into a more manageable shape. With the reel located on the main machine line, the continuous process of the papermaking machine is interrupted for the first time and switched to intermittent operation. The aim is to achieve this periodicity with the best possible efficiency so that the work already done is not wasted.

The web of papermaking machine rolls has a full width and is even more than 100 km long, so it has to be cut into sections of suitable width and length for the paper mill customers and rolled around the cores. customer rolls before shipment from o 25 paper mills. This web longitudinal cutting and rewinding is ό known in a suitable separate machine, i.e. a winder.

x In the winder, the machine roll is unwound, the wide web is cut with the cutting element

a plurality of narrower sub-webs which are wound with a winding portion around the winding cores S 30, such as cores, as customer rolls. When the customer rolls are complete, the winder is stopped and the rollers, or so-called "rollers" are stopped. the move is removed from the machine. this

C \ J

after that, the process will continue as a new move. These steps are repeated in 2 increments until the paper runs out of the machine roll, at which point the machine roll is replaced and operation begins again as a new machine roll.

In the fiber web manufacturing process, in the process of reeling, the roll of machine roll 5 is moved forward in the process typically by rolling along the rails, either by gravity (inclination on the rails) or by a separate transfer device. The transfer from the roller to the front can also be performed by a lifting device such as a hall crane. For a winder not connected by transfer rails to the paper machine, the machine roll is normally brought in by a hall crane and lowered to the transfer rails, typically 10, so that the center of the machine roll is about 2.5 meters from the floor surface.

The transfer rails of full machine rolls consist of horizontal or inclined rails to the waiting station. On the transfer rails, the machine roll is moved from the waiting station to the other until the unrolling station. The machine roll is moved from the waiting station to the other 15 by horizontal transfer rails by means of a transfer device and by inclined transfer rails by gravitational scrolling, by stopping and release mechanisms.

The unwinding station consists of a fixed unwinding arm which holds the machine reel during unwinding. The unwinding arm comprises a first 20 unwinding arm on the operating side and a second unwinding arm on the treatment side. The ends of the machine roll are unrolled during these unwinding clips. Unlocking arms are articulated with locking arms which lock the machine reel in place during unrolling. The machine reel in the unrolling position is connected to a brake generator which acts as a drive for the unroller.

δ 25

ό Usually, after unrolling, the deflated winding shaft is removed from the unrolling station by i manually lifting it by a crane or x automatically by the winding shaft handling equipment. Rolling shaft handling equipment

CL

consists of either vertical lifting gear or pivoting lifting arms and S 30 return roll rails for empty reel shafts. An empty or nearly empty o reel shaft is lifted by a hoisting device or lift arms onto return rails, which typically have a plurality of re-positioning positions, from which the reel shaft can be moved to a paper machine reel, e.g.

If the machine roll is to be moved sideways away from the rail line defined by the reel, e.g.

With a rolling machine roller carriage, the machine rolls can be moved and handed over to the rails of the receiving station or transported by a crane. A wagon with fixed rails 10 can operate only within a certain area defined by the rails. It is not possible to change the order of the machine rolls to be stored on the machine roller wagons;

Nowadays, unwinding and retracting reels utilize fixed reeling arms, in which machine rolls and reels are locked using locking jaws during reeling. The roller shaft or machine roller is brought to the platform either by rolling along the rails or by crane. After winding, the machine reel or winding shaft is moved away from the carrier, for example by a transfer device. In the scrolling position, the users have the option of deflecting the roll laterally, either throughout the roll or in one-off increments of 20 before the start of the roll. Typically, the maximum displacement is + -50 mm. The lateral displacement is integrated as a function into the scroll bar.

Unlocking and retracting reels can be used with automatic sealing machines and automatic sealing methods suitable for fixed reeling jackets.

the needs of the cycle in a flexible way. Moving and turning of the rolling shafts and machine rolls S 30 puts special requirements and takes up space on transport trolleys, which are supported on rails and / or wheels. The order of the machine rolls in the process may be

C \ J

it is difficult to change using trolleys. Rolling shafts handling solutions typically require expensive full machine roll concrete and 4 beam beams to support lifting equipment such as hall cranes. The capacity of the hall crane may be reserved, in which case the hall crane will not be able to respond to short-term transmission needs.
