METHOD AND APPARATUS FOR SEPARATION OF ROLLERS

The present invention relates to a method which, by means of adjustable elements, separates a group of paper, pulp, carton rolls, and a legal separation of the process, for example immediately in the winder, but also below. moving to a place of separation with conveyors.

The individual rollers are generally separated from the groups by scrolling n along the plane into which the separation stop array is embedded. This: from several stop elements selected by the program to the blocking position. Others turn down. Rolling Rolls; those who encounter stop stops in the stop position will stay in the stop position and others will continue to move forward. Typical separation stop o in Finnish Patent Publication 97126. Each element of said n stop is provided with its own air. Known separation stops also use hydraulic cylinders. In lower-evasive structures, the roller p> in a very short distance. In this case, the chances of slowing down the Rull before the stop is very limited. In practice, the damping capacity of the ti stops is almost non-existent.

It is possible for upper receivers to arrange motion v over a longer distance, and the stopping becomes softer, solutions are described, for example, in Finnish Patent Nos. 91315, 90035 and 104367B.

There are other drawbacks to the prior art. The rolls mi i * V have evolved in a direction unfavorable to handling as the maximum roller diameters have grown to two iro 2 11 divisions remain a problem for production planning. There are often rolls of different widths in the same shift, but the borders of the stop elements are often not the same: A fully freely programmable stop is achieved> the stop element width is less than half the minimum roll width. Therefore, the change of 150 mm wide rollers in selectable positions e the width of the elements of the separation stop line must not exceed 70 r requires a stop of seven meters with a group of rollers ^ In known structures, with its field cabling / tubing rises very high.

The stationary Rull, which is stationary, for example with a lamellar conveyor, can also be separated by means of diverting pushers for the diaper surface. Known solutions resemble p; In many cases, the same structure can be stopped by the utility (as a recipient) and pushed. As described above, the problems of the rollers also apply to the separation by pushers

Especially in order to separate large rolls, you often have to apply considerable separation force. The reason may be staggering and / or uneven cutting surface.

Also known are solutions for separating rolls by about · "longitudinal movements. General method or at the seam of two successive conveyors. Separate hits, also pushes to the side Separation at the conveyor seam can cause rolls of • V diameter / width ratios to fall in. This separation has to be done in a fixed order, which differentiates the active or passive position of the molding device from the element. concerned.

The invention provides a decisive improvement in the above disadvantages. To accomplish this, the invention is characterized by what is disclosed in the independent claims

It is essential for the invention to provide a whole new method of separating a plurality of separating elements in active or passive positions into permanently positioned power units. You go applicable in many, very different embodiments.

The main advantage of the invention is that even a fractional separation can be achieved using only a few vo. Compared to prior art, the number of power plants and drops to less than one-tenth. This has a major impact on i and maintenance costs.

Some embodiments of the invention will now be described in detail with reference to the accompanying drawings.

To turn the obstacle to the release position, the adjusting member 7 ki anticlockwise. The cam 8 then engages the slot 5 of the support 5 forcing the support 5 to turn with it. Wheel 6 turns from P1 to PO. At the same time, the barrier 2B rotates due to the effect on the release position (= rolling levels 2A, 2B parallel).

The force on the pivoting of the setting member 7 is transmitted through an inner transmission which pivots with the groove in the shaft 10, providing the 'power unit 17 shown in Fig. 2, for example via a tooth 18 and a gear 19. Shaft 10 pivots for landing Bearings 20 in mounted housing 21 are guided by a long housing 11 in the landing beam 22 which provides guidance for both brackets 5, alignment member 7 and shaft 10

The positioning means 7 with its cams 8, 9 and the shaft 10 and the wheels 6 form a positioning mechanism 36.

The transferring of the positioning member 7 between the supports 5 is carried out preferably by means of the transmission wheels 24 and the chain 25.

The isolation apparatus according to the invention is controlled by ec programmable logic. Many other options are rr For example, for applications requiring very high setting speeds, two-axis NCs known from machine tools can be used.

If necessary, the obstacle settings can be changed along the same (long) distance of the € setting element 7. As well, a 7 can change only one obstacle setting, e, allowing a single roller to roll.

In some situations, it is advantageous to turn not all at the same time in either the inhibit or release position. The head is obtained by removing air from the bellows (s) 1, the lowering beam 22 turns counterclockwise under the guidance of the rs on the shelf 14. In this case, all the supports 5 release the obstacles 2B task down.

Simultaneous lifting of the barriers 2B to the locking position is effected by the actuators 1 to 5 clockwise on the levers 27 which are pivoted; ends. The lifting beam 16 between the levers forces the supports with 5 hands and, via the rollers 6, lifts all obstacles 2B

Figure 3 shows a push-based separation apparatus. The roller (moving) rests in the separating station, e, with the lamella conveyor 28. Similarly to the above, the pusher element 30 is set to the "active" position, with 1 turned to the P1 position. The pusher element 30 attaches to the beam 32, which is mounted on the frame by means of the hinges 33 and the pivoting mechanisms of the supports also attaches to the beam 32.
