Description

The present invention relates to a winding and Abbindeinrichtung for an elongated Good, in particular hose, pipe or cable, with a winding station for producing a multi-layer winding roll about a central winding roll axis, a setting station for toroidal setting of the multi-layer winding roll and with transport means for transferring the In the winding station created winding roll in the setting station.

Such elongated goods such as hoses, pipes or cables are often produced continuously. This continuously produced elongated product is wound up in a winding station to form a multi-layer winding roll. This winding is usually carried out on a winding core, which is provided with flange-like discs. For example, if the elongated product is a cable, it is usually left for further transport and further processing on this coil consisting of winding core and flange-like disks.

In particular, in hoses or pipes but winding rolls are to be produced, which are free of spools and which must be tied to maintain the shape and stability in the toroidal direction. The winding roll created accordingly in the winding station must therefore be brought to the setting station, wherein it should be avoided that the winding roll loses its shape during the shifting and Abbindingvorgangbeginss and even entanglements can occur within the winding roll. For example, drip irrigation tubes, which are produced in such a way and processed into winding rolls, are very delicate, since the material is relatively soft and the walls are sometimes very thin, which can lead to squeezing of the tubular body or entanglements of the winding roll if too coarse treatment, which the quality of massively impaired thereafter to be laid and in use drip irrigation tube, and may even lead to such a wound drip irrigation tube can not be used.

The object of the present invention is therefore to design a winding and setting device in such a way that it is ensured that the elongated material to be wound up and tied down can not be damaged during the machining process, so as not to impair the desired qualities of the elongated material.

According to the invention the solution of this object is achieved in that the means of transport are formed by a movable between the winding station and the Abbindstation car, which has at least three distributed over the circumference of the winding roll arranged rollers which are fixed to arms, which are arranged on the car, in that the rollers can be set substantially radially against the winding roll and can be turned off from it, that the rolls are set to the winding roll when the process is ended, that by means of the rolls employed on the winding roll during the process of the carriage, the winding roll is displaceable along a slide plane into the setting station is and the roles are employed during the binding to the winding roll.

By means of this solution according to the invention, it is achieved that the resulting winding roll is held permanently by the rollers distributed over the circumference and remains in shape so that during the transport of the winding roll from the winding station to the setting station the winding roll is also permanently held by the rolls during the Abbindvorgangs the case. This ensures that the winding roll is held from the formation process until setting uninterrupted and similar, whereby the shape of the winding roll is maintained and is avoided that, for example, a pinch or entanglement of the elongated material can occur.

Advantageously, the Gleitbahnebene the shape of a table on which the winding roll wound in the winding station, moved by the movable carriage in the Abbindstation and tied off there. The horizontal laying of the winding roll on the table, this can be optimally maintained.

Advantageously, the winding station has a diameter-adjustable and axially movable winding core, which is limited by a first disc and a second disc which is movable along the axis of the winding core, whereby optimal winding rollers can be produced.

Advantageously, the first disc is integrated into the slide plane, with the result that the winding roller to be moved without paragraph of the second disc can be moved to the table.

Advantageously, the carriage is slidable along linear guides disposed between the winding station and the setting station, resulting in ease of operation.

In order to obtain optimum support of the winding roll by the rollers, they are aligned parallel to the winding roll axis.

Advantageously, the rollers are driven, which makes it possible to rotate the winding roller in the Abbindstation to the winding roller axis, which can be achieved to attach bindings at different locations on the circumference of the winding roll can.

A further advantageous embodiment of the invention is that the arms are designed as pivoting levers, one end of which is pivotable about an arranged on the carriage, aligned parallel to the winding roll axis pivot axis and at the other end a roller is arranged, whereby a simple structure can be achieved ,

However, the pivot levers may each be connected via an axle piece, which forms the pivot axis, with a control lever, wherein the pivot axis is mounted on a sliding element which is displaceable along the linear guides, and the control lever is pivotally connected to a linear drive, the radially against the reel shaft axis is aligned when it is in the car. This will be a optimal movement when adjusting the roles obtained on the winding roll, control lever and linear drives can be arranged below the table, whereby the rollers can be arranged very compactly.

Advantageously, the pivot lever via drive mechanisms are pivotable.

A further advantageous embodiment of the invention is that the Abbindstation is equipped with an ejector, by means of which the finished set winding roll can be ejected from the Abbindstation.

Advantageously, support rollers are used in the region of the Abbindstation in the slide plane, which are aligned radially to the winding roller axis when the winding roller is in the Abbindstation. As a result, a rotation of the winding roll is simplified to the winding roll axis.

In an advantageous manner, a holding-down device having the shape of a plate is arranged in the setting station, which can be lowered onto and lowered from the settable winding roller. This ensures optimum retention of the wound roll to be tied in the setting station.

Advantageously, further support rollers are used in the plate-shaped hold-down, which are aligned radially to the winding roll axis when the winding roll is in the Abbindstation. This has the consequence that the winding roll to be tied off can be rotated more easily around the winding roll axis.

A further advantageous embodiment of the invention is that the setting of the winding roll is carried out with a stretch film, which ensures that the local pressure in the region of the stretch film is not too large on the elongated Good to be tied, which can be avoided that the elongated Well squeezed in this area.

In Fig. 1 is a wound roll 1 produced with the later-described inventive device, which is formed from a wound, elongated material 2. This winding roll 1 has been tied with a band-shaped stretch film 3 in regions and toroidal, with which the wound elongate material 2, which is arranged in several layers 4 superimposed, is held in position. This winding roll can be easily transported in this form, the individual layers 4 can not move against each other, the Local stress by the stretch film 3 on the elongated Good is minimal, even if this elongated Good 2 is formed as a tube, which is made for example of a soft material and has a low wall thickness, as used for example for drip irrigation, is the danger squeezing virtually impossible, the tube quality is maintained.

The inventive winding and Abbindeinrichtung consists, as in Fig. 2 is shown, from a winding station 5 and a Abbindstation 6, which are arranged in a machine frame 7. Also held in the machine frame 7 is a table 8, which is oriented substantially horizontally, and which forms a slide plane 9. In the area of the winding station 5, a first disk 12 is inserted into the sliding surface 9, as is clear from Fig. 5 it can be seen, which is rotatably mounted in a known manner about a vertical axis. This first write 12 forms part of a coil 11, on which the elongated material 2 can be wound up.

Lowerable vertically on the first disc 12 is a second disc 10, which is provided with a winding core 13, as also out Fig. 5 is apparent. This winding core 13 is adjustable in diameter in a known manner, not shown.

How farther Fig. 2 it can be seen, is wound on this coil 11, formed by the first disc 12, the second disc 10 and the winding core 13, the elongate Good 2. Here, the elongated material 2, which is continuously produced and this winding station 5 is supplied, performed in a known manner by appropriate pulling and guiding means to the coil 11. The two discs 10 and 12 and the winding core 13 are hereby likewise set in rotation in a manner not shown, known manner via a drive.

How farther Fig. 2 and also out Fig. 4 it can be seen, four rollers 14 are supported on the circumferential surface of the resulting winding roll 1 distributed over the circumference. These rollers 14 are each mounted on a pivot lever 15, whose one end portion 16 about a pivot axis 17th is pivotable, while at the other end portion 18 of this pivot lever 15, the roller 14 is mounted, which is about an axis 19 which is aligned parallel to the winding roll axis 20, rotatable.

Each pivot lever 15 is fixedly connected via an axle 21 with a control lever 22. Each axle 21 is pivotally mounted in a sliding member 23 about the pivot axis 17. The control levers 22 are pivotally connected to a respective linear drive 24, the linear drives 24 are arranged at right angles to each other on a carriage 25. This carriage 25 is slidable slide bearings 26 along linear guides 27 between the winding station 5 and Abbindstation 6, as will be described later.

By moving the linear drives 24 towards the center, the respective sliding element 23 is displaced along the linear guides 27 via the control levers 22, which leads to a pivoting movement of the control lever 22 and the axle piece 21, whereby the pivot lever 15 with the roller 14 attached thereto pivots accordingly becomes. Thus, by moving the linear drives 24, the rollers 14 can be pressed against the outer surface of the resulting winding roll. It is advantageous if in each case two diagonally opposite linear drives 24 are moved synchronously, whereby the resulting winding roll 1 is aligned centrally in the winding station 5.

Advantageously, the rollers 14 are employed in a known and not shown manner with an adjustable pressure to the winding roll 1.

From the Fig. 3 is the location of the control lever 22 with the corresponding linear drives 24 which are mounted on the carriage 25, can be seen. Accordingly are out Fig. 4 the positions of the pivot lever 15 with the attached rollers 14 with respect to the resulting winding roll 1 can be seen.

How out Fig. 5 it can be seen, is in finished wound roll 1, the winding core 13 in a known manner, not shown in diameter reduced, the winding core 13 and the second disc 10 are moved away in the vertical direction of the winding roll 1. The rollers 14 continue to be based on the outer peripheral surface of the finished formed roll 1. The carriage 25 is moved along the linear guides 27 against the Abbindstation 6 out, driven in a known and not shown manner by corresponding linear actuators, via the rollers 14, the winding roller 1 is taken, it slides from the first disc 12 on the Gleitbahnebene 9 of the table. 8 The pivot levers 15 are not moved during the displacement of the carriage 25 and thus the winding roll 1.

Out Fig. 6 the position of the carriage 25 and the control lever 22 can be seen in FIG Fig. 7 is the displacement of the winding roll 1 away from the first disk 10 on the Gleitbahnebene 9, according to the situation as shown in Fig. 5 is shown. The winding roll 1 is thus held on the one hand by the slide plane 9 and on the other hand by the pressed rollers 14 during this displacement operation, a mutual displacement of the individual layers of the winding roll 1 is thereby avoided.

Like from the Fig. 8 . 9 and 10 it can be seen, the carriage 25 is moved so long until the winding roll 1 is in the Abbindstation 6. In this Abbindstation 6, a hold-down 28 is lowered onto the winding roll. This hold-down 28 has substantially the shape of a plate 29, by means of which the wound bobbin 1 to be tied is also held from above. The so-held winding roll 1 can now be set in the Abbindstation 6 in a known manner. In this case, the Abbindring shown schematically 30 rotates in a known manner through the opening of the winding roll 1, the arranged on the Abbindring 30 roller 31 with tape-shaped stretch film is toroidally guided around the winding roll 1, while the winding roll 1 is wrapped with the stretch film 3.

The rollers 14 are each driven to rotate in a known manner. As a result, the winding roll 1 can be rotated in the setting station 6 about its winding roll axis 20. Thereby, the winding roll 1 can be tied off over a certain segment, the setting process can then be interrupted, the stretch film is cut off, the winding roll 1 can then be further rotated by a certain angle, it can be tied off a further segment of the winding roll accordingly. Of course, it is also conceivable that during the Abbindvorgangs the winding roller 1 is rotated continuously over the rollers 14, whereby a complete setting of the winding roll can be achieved over the entire circumference.

In order to facilitate the rotation of the winding roll 1 to your winding roll axis 20, support rollers 32 are used in the area of the Abbindstation 6 in the Gleitbahnebene 9, as the Fig. 5 and 7 is removable. These support rollers are aligned radially to the winding roll axis of the winding roll 1 when the winding roll 1 is in the Abbindstation 6.

Accordingly, in the plate 29 of the blank holder 28 further support rollers 33 are used, which are also aligned radially to the winding roller axis of the winding roll 1 when the winding roll 1 is in the Abbindstation 6. The support rollers 32 and the other support rollers 33 are each freely rotatably mounted.

From the Fig. 11 to 13 can be seen, the finished set roll 1, in Fig. 11 is no longer shown for better view of the hold-down 28, this has been moved to a raised position. The rollers 14 are turned off by pivoting the pivot lever 15 of the winding roll 1, the carriage 25 can be moved back against the winding station 5. During this process can already be started with the winding of the next winding roll in the winding station 5, this, the second disc 10 has been lowered with the winding core against the first disc 12, so that in turn a winding spool is formed.

As in particular from Fig. 12 can be seen, are for parking the rollers 14 of the winding roll 1 ( Fig. 11 ) the linear drives 24 have been moved into the outermost position, via the control lever 22, the pivot axes 17, arranged on the sliding elements 23 have been moved along the linear guides 27, whereby the control lever 22 and correspondingly the pivot lever 15 (FIGS. Fig. 12 ) were also pivoted.

Fig. 13 shows the corresponding position of the pivot lever 15 and the rollers 14 mounted thereon.

How out Fig. 14 it can be seen, the carriage 25 is moved back into the winding station 5, the winding of a new winding roll can be recorded.

In the Abbindstation 6, the finished set winding roll 1 can be ejected via an ejector 34 in a known manner from the Abbindstation 6, this may additionally be arranged a ramp 35 on which the ejected winding roll slides and of which the finished set winding roll 1, for example Shipping, can be removed.

Of course, all processes of this inventive device are controlled in a known, not shown manner by a central control unit.

Fig. 15 shows a first embodiment of the carriage 25, which is displaceable over the sliding bearing 26 along the linear guides 27, not shown. Also visible are the linear drives 24, by means of which the control levers 22 are pivotable about the pivot axis 17 and slidable over the sliding elements 23 along the linear guides 27, not shown. The movement of the control lever 22 is transmitted in an identical manner via the axle pieces 21 to the pivot lever 15, on which the rollers 14 are mounted. With the diagonal alignment of the linear drives 24 it is achieved that the rollers 14 are pressed radially against the wound roll to be wound.

Like also out Fig. 15 it can be seen, the rollers 14 via an electric motor 36 and a belt drive 37 are driven in rotation.

Fig. 16 shows another embodiment of a structure for a carriage 25, in this case, the pivot lever 15 are held on a fixedly fixed to the carriage pivot axis 38, via a piston-cylinder unit 39th These pivot axes 38 are pivotally mounted on the pivot levers 15 rollers 14 are thus pivotally adjustable to the corresponding winding roller. The transmission of the pivoting movement of a pivot lever to the adjacent pivot lever via a mounted on the pivot axes 38 gear transmission 40. Again, the rollers 14 are driven, which in turn takes place by an electric motor 36 and a belt drive 37.

In the examples described above, four rollers 14 are arranged on a carriage, of course, a different number of rollers 14 could be used. It is readily conceivable that, for example, per swivel lever 15 two rollers are arranged, which are arranged for example on the ends of a swivel lever mounted on the pivot lever to compensate for the contact pressure to the respective winding roller. It is also conceivable to use a double roller instead of a roller 14.

In the examples described above has been spoken in each case of a stretch film as a bonding agent, of course, other materials can be used here, which can meet the desired requirements.

With this inventive device can be produced in an optimal manner continuously wound rolls and set in the desired manner, these rolls are optimally maintained in a stable form.
