METHOD AND SYSTEM FOR HANDLING AND SHELFING RAMS

The invention relates to a method for treating wreck rolls as defined in the preamble of claim 1, to a wreck roll as defined in the preamble of claim 8 and to a system for handling wreck rolls as defined in the preamble of claim 10.

10 Paper and board mills produce so-called reel rolls during normal production for a variety of reasons, which may be of prime or inferior quality. The reasons for such production may be, for example, production exceeding the order, with 15 rolls left over, quality defect in paper or board, mechanical damage during transport of the finished rolls, pre-shipment cancellation, etc.

Surplus spools of reed are usually kept for a while if there is a market for them, but 20 defective spools are removed as quickly as possible. One way is to pulp them immediately and return them to the manufacturing cycle. Often, however, due to production fluctuations, • reel rolls have to be stored and waited for production to match the material of the reel rolls. On the other hand, a defect in a reel roller often prevents it from being returned immediately; sin cycle.

'Although the amount of wreckage generated is very small in relation to the mill's total production, it is • 30 significant, requiring large inventories if stored for long periods. Due to these factors *, most of the reels are sold to dealers, ;;; which deliver them to suitable applications for pulping.

; ; : 35 This out-of-factory sale of broken goods: * ·, however, raises several issues. The factory is unable to verify whether the sold reel rolls will be pulverized or resold by the dealer for further processing. There are problems with the factory's own spinning reel trade because at the same time and on the same market, their reel rolls, which needed to be pulverized, are on sale. Even a small batch of the same item sold at significantly lower prices can cause serious price disruption. In addition, the factory may, in the worst case, receive complaints about its reels for sale-10 dies when the dealer has sold them prima facie and the final customer identifies the original factory from which the reels originate.

The problems described above have been avoided by splitting the reel rolls, after which they are murs-15 covered and baled. They are then stored as bales and, if necessary, resold for pulping to suitable applications. This is a working arrangement in itself, but it also has some drawbacks. Most paper and board mills do not have the ability to process pulp piles on pulverized lines, which are constructed only as pulping lines for rejected rolls. On the other hand, it seems pointless to split and crush the reel rolls and immediately pack them in a new package when the original package, or '25 rolls, is already in the most compact and easy-to-carry form.

; \: From these problems, kek-:: has persisted in developing a solution that aims to prevent reel-to-reel access to primeamark-30 cinemas, reduce the reel handling stages and • 1 · 1, handling costs and preserve the reel material • • with such properties as to be pulverized and reused in the same or similar processes without problems.

··. ·, 35 Aspects of the invention; with reference to the claims.

3, 116520

In the process of the invention for treating paper and board industry reels prior to pulping and reusing, the original reel shape of the reel is retained and the reel reel 5 is labeled with a transverse layer that prevents lat is intended.

Preferably, the marking is made through all layers of the reel roll up to the winding sleeve or at least through enough layers, for example from the periphery to the winding sleeve, so that it is no longer economically viable under any circumstances to remove some of the layers from the reel 15.

Preferably, a plurality of markings are made on different sides of the reel roll, for example, on several sides of the cylindrical shell, and possibly also on the ends of the roll 20.

In one embodiment of the invention, the marking is made by drilling a hole through the layers of the reel roll. Drilling can be done with one blade hole at a time, or with a suitable set of blades, multiple holes side by side or * '1 25 suitably from different sides of the roll simultaneously with several • s drills that support each other during drilling. 1 V In another embodiment of the invention, the designation is • · ·:! This is done by piercing the layers of the reel roll with a suitable hole punch and / or sharp spike which is pressed deep into the roll.

In the third embodiment of the invention, the designation "·" is made with a strong pressure flow such as a water or air jet. Such a shear jet stream can make punctured holes, larger holes, or ♦ shear lines of various shapes. Essential water • · »; or the air jet also has the effect of not damaging or altering the properties of paper or paperboard, as would be the case with 4116520, for example, a laser beam when burning material. Thus, for the marking method of the invention, it is also essential that the marking be made without altering or destroying the properties or composition of the paper / board surrounding the marking.

A further object of the invention is a reel for the paper and cardboard industry. According to the invention, the reel reel includes an marking extending through the paper or cardboard layers that prevents the use of the paper or board web 10 comprising the reel reel for its original use. The marking 1 extends to a significant and substantial depth from the outer surface of the reel roll inwardly toward or parallel to the winding sleeve, possibly up to or even through the winding sleeve.

Preferably, the marking is formed by one or more reel rolls through the layers, a piercing hole, a piercing, or the like, which breaks and punches a roll or paper web comprising several successive positions of the roll.

The invention further relates to a system for treating scrap rolls in the paper and board industry. The system includes a transfer arrangement for moving the resulting reel rolls away from the factory, such as from production and storage facilities. The transfer arrangement may be * ,,, · carried by lorries, train wagons, waterways • 1 · 'or shorter distances on different conveyances or: directly by truck. Likewise, the system has a waiting warehouse for intermediate storage of off-shelf rollers 30 prior to selecting an end-use.

• »This allows you to store large quantities of different types of * T waste rolls, sort them and find a suitable end use. The system still includes a tag arrangement for marking a reel roll with a mark extending through its layers 35 in the waiting roll of a reel roll! . when transporting, and a transport arrangement for the transport of * 116520 marked rollers to the selected end-use.

Thus, an essential feature of the system according to the invention is that, when manufacturers of wreck rollers use a reliable wreck roller dealer, the wreck rolls in the waiting stock are not processed in any way, but sorted and stored to find the optimum destination for them. Once this application has been found, that is, when the reel rollers 10 are started to be removed from the waiting warehouse, they are marked with the marking according to the invention. Immediately after being marked, they can be transported to a recovery site or further labeled, sorted and collected, for example, in appropriate batches, which are then periodically shipped according to the wishes of the 15 customers.

In one embodiment of the invention, the marking arrangement includes a piercing unit arranged in connection with a truck or other similar transfer device for marking a reel roll 5 20 to be moved from the waiting warehouse to the transport arrangement. In other words, there is no need for any separate marking operations on the reel reel, but only when the truck, train carriage, ship's hold or the like is lifted from the waiting warehouse by means of the inventive marking device.

In another embodiment of the invention, the marking arrangement includes a fixed punching unit in which the reel rolls selected for a particular end use are brought from the waiting warehouse before being moved to the transport arrangement.

30 Such a piercing unit may be a separate device to which the reel rollers are imported and from which the marked reel rollers are further applied for loading into the transport arrangement. On the other hand, it may also be a suitable transfer conveyor, on which the rollers are brought and moved along the transport arrangement. Transferring to Jet Propulsion Sit- * t »! . it includes a marking device which marks each roll passing by in a specific manner.

It is also possible, within the scope of the inventive idea, to use a movable and carried unit as the piercing or marking unit. Thus, the marking according to the invention can be made on a case-by-case basis, either in connection with a waiting warehouse, directly at the factory or in its immediate vicinity or, for example, in a port to which reef rolls can be transported directly from the factory without intermediate storage.

The method, system and reel roll of the invention have significant advantages over the prior art. The reels do not have to be individually split, crushed and baled in re-transportable form, but the reels remain in roll form throughout the inventive treatment. The inventive marking 15 guarantees with certainty that the reel roll cannot be used for its original or similar purpose, but is only re-usable through pulping. While remaining in the form of a reel, the reel roll can be pulverized at any paper or board mill where pulping reels have been pulverized.

In the following, the invention will be described in detail with reference to the accompanying drawings, in which Fig. 1 shows a reel roll marked ft r t '25 according to the invention and Fig. 2 schematically shows a system for handling reel rolls according to the invention.

: Figure 1 shows a roll of paper 1 with paper wrapped around a carton sleeve 2. Thus, the reel has a cylindrical outer shell 3 and a circular end 4 on the roll. The perforations 5 of the outer shell 3 are perpendicular to the carton sleeve 2, i.e. holes drilled at least close to the outer shell. kartonkihylsyyn. In the application of Figure 35 1, two to three rows of holes are drilled! . with all holes at different positions along the length of the roll *.

In the diagrammatic representation of Figure 2, in the system of the invention, about 98% of the production of the paper mill 6 is generally prime material 7 that goes directly or through a warehouse to customers. During the start-up of the machines 5 and during shutdowns and quality changes, there is usually a certain amount of wreckage 8. Wreckage may also include that part of prime merchandise that is not commercially available for one reason or another. The wreckage is stored in a wreckage warehouse 9, from which it is transferred to a waiting warehouse 10 by means of a suitable transfer system 10. The waiting warehouse 10 has a plurality of storage locations 11, which allows sorting and storing of different grades of wreckage rolls before handling and delivery.

The system further includes a marking system 15 ly 12 for marking the reel rolls with a mark extending through the layers of the roll. The rolls can be marked inside the warehouse building by taking rolls from the waiting store 10, which are marked and transferred to the marked rolls waiting room 13 to wait for delivery. This second waiting warehouse 13 also has a plurality of storage locations 14 which allow the storage of labeled rolls of different quality in different storage locations.

- f * 'j Another possibility is that from the waiting warehouse' '' '25, the reel rolls will be taken into consideration in the marking arrangement 12 only when they are delivered for further processing,' ', i.e., when the truck 15 is already waiting for their loading. The reel rolls are then transferred from the waiting warehouse 10 to the marking arrangement 12 and from there directly 30 to the waiting truck 15.

, ** ·. By truck 15 or, of course, by other suitable transport arrangements, the reel rolls are transported to suitable factories 16 for pulping and reuse or, for example, to port 17 for port 17 and further transport.

The invention has been described above by way of example only with reference to the accompanying drawings, in which various embodiments of the invention are possible within the scope of the claims.
