105667

BACKGROUND OF THE INVENTION The present invention relates to a cellulose sheet bale binding machine consisting of a bale, wrapper and baler.

Today, cellulose is generally supplied to the user in baled sheets.

10 Cellulose sheets are pressed into bales, for example, weighing from 200 to 250 kg. The bale may also be wrapped in cellulose, paper, or the like, and wrapped with twine yarns. The bale is then rotated 90 ° The wrappers opening at the end are folded and the bale is reattached by means of transverse tying strands 15 transverse to the first tying threads. The bound bale thus wrapped is grouped together, for example, into a set of four bales, and the large bale thus formed is bound e.g. Thus, there are many jobs involved in forming such a large bale. • Steps, all of which require different movement and translation • • «* steps. In addition, a considerable amount of binding yarns are required for binding.

The device according to the invention is characterized in that the conveyor line, after the baler press, has a bale grouping apparatus in which the individual bales are assembled into a larger unit, a large bale, and then a large bale wrapping and binding station. .

The invention also relates to a method of bonding cellulose sheets, in particular wrapped cellulose sheets, wherein the sheets are compressed into bales and wrapped and bound. The process is characterized in that a plurality of compressed bales are joined together to form a large bale, which is bound with binding yarns. Prior to binding, the large bale may also preferably be wrapped in a protective cover.

According to a preferred embodiment, in the method according to the invention, the bales are pressed in a horizontal position, after which the bales are rotated 90 ° (wherein the sheets are vertical) and at least two successive bales are grouped together. Thereafter, said combination of at least two bales is wrapped by wrapping the wrapper horizontally around the combination followed by binding of the wrapped, said at least two bales.

According to another preferred embodiment, in the method of the invention, the bales are pressed in a horizontal position, whereupon the bales are grouped by lifting at least two successive bales over one another. Thereafter, said at least two bale combination is wrapped by • wrapping the wrapper vertically around the combination, followed by binding of the wrapped, said at least two bale combination.

In the method according to the invention, the pressed bales can be grouped together successively on a conveyor to form a large bale lying which is wrapped. The bales can also be stacked directly on top of each other in a large standing bale which is wrapped and tied upright.

The invention further relates to a large cellulose bale consisting of pressed. cellulose sheets and wrapped in cellulose, paper or the like and bound with a binding yarn. A characteristic of such a large bale is that the large bale consists of two or more individually pressed cellulosic sheets, each of which is wrapped and bound in a manner known per se.

The invention will be explained in more detail with reference to the accompanying drawing, in which

Figure 1 schematically illustrates the present bale wrapping and binding method, and Figure 2 schematically shows the apparatus, method and product of the invention in the form of a baling and binding line.

Figure 1 shows the current baling method in which the stack 4 formed by the cellulose sheets is pressed (not shown) into a bale. In Figure 1a, bale 4 is wrapped with wrapper 6, which may be cellulose, paper or the like. The wrapping agent is not necessary, it is often omitted. Two partially bound yarns are wound around the partially wrapped bale thus formed. The bale ends are still open (1b). The bale wrapped in this way is rotated by 90 ° on the bale conveyor and the wrapping material protruding from the ends of the bale is folded over the ends of the bale 15 to form a fully wrapped bundle. Thereafter, two tying threads are typically twisted in the longitudinal direction of the bale, after which the bale is completely wrapped and tied in all directions in the example case with four binding threads.

♦ M

«_______ •« «· • · • · ·.; ' '' 20 The required measures are as follows: Wrapping material is placed around the bale • · * · · (1a); moving the bale to a binding position where the wrapping material is wrapped around the bale and • the bundles of transverse bundles are wrapped around the bale (1b); after this, the bale is moved forward and rotated horizontally 90 ° with respect to the position of Fig. 1b • · ·, at which position the ends of the wrapping material are folded and 25 longitudinal bundles of twine are placed.

• · · • · * *. In order to optimize transport, the bales are formed into larger units, ie • r.

large bales, whereby for example four wrapped and bound bales can be stacked • · "· * on top of each other, and the resulting bales are further tied as described above.

The two or more large bale described above can be further combined into a larger maximum bale assembly, which then: is bound as described above.

Thus, the present tying method and apparatus comprises a very large number of steps in which the bale is moved from one treatment station to another, the bale is inverted and it is wrapped and bound. Even a slight malfunction in these many stages complicates the overall operation of the device, and the device does not have the best capacity. In addition, the binding of individual bales and large bales requires a large amount of binder yarn, which can be very costly, especially on an annual basis.

The object of the invention is to avoid these drawbacks and it is proposed, as shown in Figure 2, that the many time-consuming and slow-down wrapping and binding steps be dispensed with. The large bale or even larger bundle formed from it shall be wrapped and, in the recommended case, bound only once. This saves work steps (transfer, turning, wrapping, binding, etc.) as well as the 15 large amounts of binding yarn required for multiple binding.

As shown in Figure 2, the device consists of a bale conveyor 1 known per se, with the cellulose sheets stacked on top of each other. This stack of cellulose sheets «· * * ;; pressed in a press 3 into a bale that is turned 90 °, assembled

. see cellulose, paper or the like. The wrapper 6 is positioned relative to the large bale 5 so that the major folds of the wrapper are substantially at the ends of the large bale, facing the first sheets of the bale ends, and on the sides of the bale the wrapper 25 touches the edges of the sheets.

In the case shown in Fig. 2, the bales 4 are connected in series to form a large bale 5 lying down. After wrapping, the large bale 5 is tied and • · raised, if necessary, to a vertical position 7 so that the large bale wrapped can be attached. 0 30 with a second large bale into a bale assembly 9 which, by means of a conveyor, moves to a tying station 8, where the bales are tied together and a bale assembly 10 is formed, the so-called. transport unit.

Figure 2 shows a case where bales 4 are placed one after the other on a conveyor. Another option is to place the bales 4 on top of each other. This standing large bale is wrapped and the wrapped bale 7 is transferred to a binding station 8.

Figure 2 further illustrates an embodiment in which a wrapped bale 7 is combined into a bale assembly 9 having two or more large bales joined together and bound together. Of course, according to the wishes of the user, it is possible that the large bale 7 as such is tied at station 8.

According to the invention, the wrapping and tying of a single bale is avoided, with the advantage that, in addition to saving a great amount of tying yarn, the operation of the device is less sensitive to interference than the current method which involves a very large number of bale moving, turning, wrapping and tying Toja.
