Method for producing a coil-free container and container

Field of application of the invention

The present invention relates to a method for producing a coil-less bundle of stranded material, such as wire, insulated or non-insulated strands, glass fibers and the like, as well as a container produced by this method »

When processing strand form, such as in _# wire, the problem usually arises, tHe further processing of the wire does not take place at the location and often not in the operation, in which the wire itself is made. The Strandförroige Good must then be prepared in a suitable manner for transport and brought to the processing site.

This is usually done by the winding material is wound on bobbins, which are then transported together with the winding material. Therefore, a large number of bobbins must be held in the respective factories, which requires a faa: legal investment expenditure. Furthermore, the empty bobbins have to be transported back from the processing station to the production plant, which results in considerable costs. Finally, the coils also increase the transport weight of the winding material, which also entails an increase in transport costs »

It is therefore a wish of the industry that strand-like material, such as wire, should not be wound up on spools.

but is transported and delivered as a container, which consists essentially only of the actual string-shaped material itself ₀ This type of containers is commonly referred to as disposable-packed container.

characteristics of the known prior art

With DE-OS 32 20 195 a method for producing a disposable packaged container has become known.

In this known method sins conical '.Ѵісkzі-coil is used. The strand-like material is then wound in individual mutually parallel layers on this cone-shaped i-coil, whereby an adhesive is provided, which adhesively connects the single turns and layers with each other. The wire is then pulled off from the inside during further processing.

This known method and the resulting container have a number of significant parts »

A disadvantage is first the fact that an adhesive is needed for the preparation of the container, which makes the process complicated and expensive. Furthermore, this adhesive can lead to a disruption of Weiterverarbeitungsprozeeses and mu3 therefore u «U _e removed first ,,

In addition, it can lead to entanglement of the wire layers despite Haftemittels, namely, when towards the end of Aäzugsvorganres between individual layers, the adhesive forces are exceeded, so that several turns fall at once down "

Object of the invention

The aim of the invention is to eliminate the aforementioned deficiencies.

Explanation of the essence of the invention

The present invention has as its object to provide a method for producing a bobbin-free container and a container, which is simple and inexpensive to carry out and which leads to a stable, transportable without problems and processable container »

According to the invention, this object is achieved by a method for producing a coil-less container of stranded Good, such. Drant, insulated or non-insulated strands, glass fibers, and the like, in which the strand-like product is wound in layers on a substantially conical reel spool, the layers being inclined with respect to the longitudinal axis of the reel spool, and b-εі being a laying device is used, which moves in approximately parallel to the axial direction, which is characterized in that the winding process begins on the side of the reel spool, which has the smallest diameter, that first a predetermined number N- turns is applied to the '.vickelspule, said number M _-1 is smaller than the Gesatntzahl N, A & R at ar cevvählten winding pitch to the IVickelspule maximum applied number of turns, that the laying means after this number U ^ windings reach in their direction of movement is reversed, and having substantially the same number of turns It was formally good for issuing ar.gs diameter back

wraps, and that on these winding layers Ц; L ^ then in the same way winding layers L ₂ ; L ₂ ^; 1_ _χ3 ; L _x J _{3 are} applied, which are a number of N ₂ ; N ,; N windings, wherein the number of turns N ₇ ; N_ etc. at each new winding layer increases by a substantially constant winding factor Δ N until the maximum number N _m _ _w turns is reached,

(Пал

then the laying can be continued in the usual way.

In an advantageous development of the method, the winding spool can rotate during the 'winding process'. In this case, an upwardly and downwardly moving laying roller is used which guides the strand-like material to the spool in the respectively desired height. It is to be noted that in this embodiment the speed of the reel spool has to change with the change in the position of the laying device to ensure that the wire feed constant rate is any diameter of reel size same infantry speed «

GeraäS a further preferable embodiment sceht the reel spool during the winding process silent "In this case, the laying device moves around the coil ur.d lays the wire in accordance with the ilsrkrnalen the arfіпгіипг ^ сзтіа ^ зл process around the reel spool _β The strand form then has in general, a twist on, as the good is rotated at each turn ura 360 »This twist can be removed at the. \ Ь \; іскз1p the coil again by unwinding or the fly-off takes place in the corresponding opposite direction If the twist for the 'Further processing is desired, 3 _e .

In the production of strands, the twist can be increased by a further turn per turn when pulling о

According to another preferred embodiment of the method, after reaching the maximum turn number N _v , d. as soon as the first layer has reached the flange of the winding coil opposite the initial flange, winding layers are applied which are parallel to this last layer. Thereby

the advantageous, inclined shape of the winding is maintained «

According to a further preferred embodiment, as soon as a part of the IVickellage reaches the maximum diameter of the coil flange on one side, the winding is continued so that ultimately a cylindrical structure is formed. For this purpose the Verlegaeinrichtung is practically controlled in the same manner as in the beginning of the transfer, with the only difference that now decrease accordingly the number of turns _β This embodiment of the method has the advantage that the volume of the container is better utilized to advantage.

As explained in claim 1, the method is carried out so that first a layer L. with the winding number N "is wound. As soon as the number fsL has been reached, the direction of movement of the laying roller is reversed, and a position L _f . wound back to the starting point of the first layer L., which has substantially also the number of windings U, "The next layer L _2, which is wound in the same direction as the location L _1, includes a number N"> N turns, wherein the difference between the number N ₂ and the number N ^ the V / ickelfaktor Δ Μ corresponds. This winding factor is maintained substantially in all subsequent windings, so that, as desired, the preferable conical structure of the windings

Thus, β О »hehe, that the number of turns N_ represents the positions L ₃₃ and

L ,. in turn is increased by the winding factor ^ N, etc. 3b

According to a preferred embodiment, the winding factor is between 2 and 6, preferably between 3 and 5. For this winding factor is a cone angle between 12 and 16 °, preferably between 13 and 15 °, preferably "Under cone angle is the total opening angle of the reel during the Winding process understood D. h, so that is inclined at a Kegelöffnungsv.-inel of z _o Z, 15 ° dio .'lantellinie the cone in the axial section иъ 8 to the longitudinal axis of V / ickalspule ·

According to a further, preferred embodiment, the winding factor is between 6 and 12, preferably between 7 and 11. In this winding factor, an opening angle of the cone is preferably used, which lies between near 0 ° and 12 °.

The method ^{according to the} invention can be carried out with different pitches, ie the distance between two adjacent turns relative to the diameter of the winding material. It is preferable to use зіпѳ winding pitch from 1.5 to 3. This winding pitch has the advantage that minor deviations in wire height during installation and removal may not affect the stability of the package.

The container according to the invention, which contains several, consisting of a plurality of individual turns layers is characterized in that both layers are present, which are parallel to the cone angle of the winding coil and Lagan, which extend at an acute angle to this cone angle.

5 у

The acute angle which the layers assume at the angle of the kink is greater than half the angle of the cone ·

The rope-shaped material can be wound up with orall or without a twist

Advantageously, the container has a cardboard core. The container can also be held with circulating belts in its initial state.

It is also possible that several individual Tsile of a strand-like material, for. 3, several single thin wires are wound together.

With the method according to the invention a possibility for the production of disposable packaged containers of strand-like material is made available, which has considerable advantages over the methods known in the prior art.

Due to the special control of the winding, it is possible to create containers which are formed in the manner of a double cone, so that the individual turns can be supported gegenoinander. As a result, the structure of the container for transport is much more stable, without the need for an adhesive.

The method according to the invention furthermore leads to the finished container being able to be handled in a particularly simple and secure manner. So it is in principle possible to withdraw the container both from the inside and from the outside, 3eim inner liner, the container is usually arranged so that the longitudinal axis of the container is vertical and the larger inner diameter of the container is below. If this wire is then deducted from the inside, is due to the by

the conical IVickel coil is supported by each wire turn from the underlying wire turn, so that the wire turns can not fall down.

However, it is also particularly advantageous to use an external extraction method which can not be carried out using the binders known in the prior art. In this method, the container is also arranged with its longitudinal axis in the vertical direction, in such a way that the smaller inner diameter of the container below bsf indet _a . \ n- Finally, a pulley is placed on the container whose diameter is equal to or greater than the outer diameter of the container, and which can preferably rotate · The strand-like Good, d. h, z. B ₀ dsr wire, then it is deducted "overhead", ie, it is passed on this disc · Even with this deduction form, the package is so deducted that the '.' / Indungen 'mutually supported, so that each turn of is supported by a lower '/' indung whose '.Vickeldurchmesser is greater than the diameter of the preceding .Vindung. As a result кзпп сііэ оЬэгэ .. 'indur.p will not slide down.

Thus, the container also remains stable at the external extraction in еіпзгл зэог, which makes it possible to intermittently stop and retrieve the withdrawal process without having to be afraid that 'väiTsnd dos standstill ..ілсіилдзг. ^ зг- slip and the ctrangförnige good thereby entangled »

The stability of the Gabindos orl3io! Also makes the transport essential

The process according to the invention can be carried out with so many different strand-like material. Mentioned is already that

Wire winding, for which this method is particularly suitable. Furthermore, a high suitability of the method for the simultaneous winding of several, twisted or untwisted wires was found. Fulfilling this requirement is a particular advantage of this method, since the simultaneous winding of several wires, which subsequently have to be unwound and separated again, plays an important role in wire production today.

Furthermore, it is possible to wind already finished strands and also insulated strands and the like cable with this method. In addition, glass fibers can also be wound up in an automatic way.

Oie laying of the strand-like material »in the present case, a wire, begins at the flange of the reel spool, which is arranged on the part of the reel spool, which has the smallest diameter · The wire 12 is made of green clay, dio described in more detail below, initially loose over led the second flange 4, the laying then begins with the wire winding 20, which represents the first guided to the IVickel coil winding. The transfer takes place with a put-down roller 21, the up control and is moved downward, and which feeds the substantially incoming at a constant speed wire 13 of the rotating reel spool "Dis controlling the Verlogorolle 21 is best in Figure" 2 recognize ₀ The Laying begins with the laying of the layer Ц, in which case 4 turns are wound in the direction of the arrow 22 in the present case. »Subsequently, the laying roller 21 reverses its direction of movement and winds 4 turns back, forming the layer Ц ^. The winding number UL of the layer 1 is thus 4. Then the layer L _{2 is} wound, where the number I M of the turns is given by the equation:

N · N, - 1 + Δ Μ

calculated. In the present case ^ N = 4, d "h. coincidentally equal to the number N _{1 of} the first layer L ₁ . The layer L "therefore contains 8 windings, which are wound in the direction of the arrow 22, the layer L 1 then likewise contains 3/4-turns, which have been wound in the direction of the arrow 23. Next position L has then N + + il = 8 + 4 = 12 windings

not shown position L. then 16, the situation 1 then

20 USW ₉ Thus, the number of windings is increased by a new amount wound in the same direction. Of course you could this Sotrag too

vary, if this is more advantageous for the construction of the container.

The continuation of the winding process is best with reference to FIGS. 3 and 4 clearly "The laying process is continued in the manner described" until finally the number of Win applications is so high that the opposite first flange 3 is achieved with the windings »Once this As can be seen, the following layers are wound with the same number of turns, resulting in parallel layers of wire. This course of the windings is shown schematically by parallel dashed lines 25 in FIG.

The winding of the parallel layers is continued until the outermost edge of the second reel flange 4 is reached. Thereafter, the winding process can either be ended, or it can be continued, in which now a reduced number of turns, virtually untwisted as at the beginning, be applied so that the container receives an outwardly cylindrical shape. The end of the wire 26 'is then returned to the starting point of the winding process in a few branches 49 with a large slope, and then lies ітэЬзп the beginning of the wire 12 »

The schematic structure of the wire winding is best seen in FIG. 4. The wire bundle consists of an inner tail 40, which is biconical shaped, d. h "Ca it ?, inwardly tapered narrowed and tapered outwardly he weitert" This biconical shape brings the advantage wesenüichon NRIT, since ^ is unwound, Viann represents the wire іплзгоп, reached during Abvvickelvorgang tv.nzr critical camp, located the diameter of the ".Vicklungon, in the upright condition of Gebindas,

extended downward, regardless of whether it is deducted from inside or outside. In this way it is, _o 3 "possible to create container as a commodity, dia not to specific conditions boin Kundsn whether there nönlich an internal or external trigger takes place, need to take into consideration"

In addition to this biconical part 40, a parallel-running part 42 is present in the illustrated embodiment, the diameter of which also increases towards the bottom. It should be noted, 6a this parallels part 42 can of course also be omitted, it is easily possible to build the container only from the biconical part 40 »

At the parallel part 42 then joins the rich Ee 43, in which the layers are arranged so that there is a cylindrical outer shape of the container, this can be achieved z, 3, in which the winding process used to produce the first Part of the winding led, exactly uuiradreht 'лігсі ,, Of course, this part of the winding can be omitted.

In Fig. 5, there is shown a ready-to-use container obtained by the method according to the invention. The container has a paperboard sleeve 1C, which gives additional stability to the inside, and besides that, the outer sleeve 50, e.g. »3, a plastic film intended to protect the container from dirt during transport, additional stability for transport is obtained by dissolving on 51, which are wrapped around the Gebinda, as shown in FIG Loirsifungsn to егізісіі-

Corresponding channels are already provided in the winding bobbin. Furthermore, plastic or steel belts 52 extending in the circumferential direction are provided, which continue to give the container stability.

FIG. 6 shows how the winding material can be removed from the container without the use of a device. This is achieved by positioning the container upright so that the smaller diameter of the container points downwards. The wire 56 is then preferably pulled off through an eyelet, not shown here.

In the same way it is also possible to remove the finished container inside. However, in order to make proper use of the effect of the double cone, the container is set up in such a way that the part with the larger diameter of the container points downwards. Thus, it is rotated by 180 with respect to the illustration in FIG. Such an internal trigger is shown in Fig. 10, in which case the wire 95 is withdrawn from the ilitte 96.

In Fig. 7 it is shown how the container gof.täß rig »5 is withdrawn using a device. Inserted into the paperboard casing 10 of the container is a take-off device 60 which consists of a core 61 and a rotatable disk 62 which, at its outer beginning, carries a circular ring 5 '. DXa disc S2 is vorzucs'vaise rotatable rsscαΐΐοΐ "Ээг deduction then takes place on disss disc by placing the stranrförmigs well by one in the axis of the container ^ за 55, which on Пізг not dargsstsllta '..' aise nit аэг . \ Ьлцдзѵог '"іс! і: -гг is connected, is pulled»

As can be seen from Fig. 7, the individual turns are withdrawn successively, each subsequent turn in this region of the bundle having a larger diameter than the underlying turn _β. This prevents slippage of the turns downwards, and it can during the Deduction, in particular bsi еіпзп standstill of deduction, do not come to tangling of st rs ng f огп.гдэп CLtos.

Let it be emphasized once more, that the 'v ^ onab' 'i:; However, it is of course also possible, and is also within the scope of the present invention, the wire from the inside after the З с с с с с с с с с с с с deduct "
