Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus for coiling flexible lengths of material 26, in particular cables, tubes or pipes, in particular plastic corrugated tubes, for packaging, comprising at least one drivable a frame 2 with a reel 3a, 3b and a guide device for the material 26 to be coiled on the reel, the guide device being pivotable and resiliently movable towards the reel core 4; one member 6, 25 arranged so as to be able to exert a constant pressing force on the material to be wound in the radial direction of the reel;
A member which is movable in the axial direction with respect to the reel core 4 under the action of the material 26 to be coiled on the reel core 4 and which applies a constant force to the material in the axial direction of the reel. The present invention relates to a coil winding device comprising the other member 5, 25 in which the sliding resistance to the movement of the member and the resulting force in the axial direction are adjustable.

A device of this type is disclosed in British Patent Specification No. 980903 (GB-A-980903). This prior art device is particularly suitable for winding large quantities of copper wire, in which one member of the guiding device is a roller placed over several windings, and the other The members are radially projecting sides of the member of small dimensions. However, there is no disclosure of any element for applying an axial force on the wrapping material also from the other direction so that successive layers can be wound.

Therefore, this prior art device could not be used for any purpose other than the specific purpose for which it was faced.

The present invention provides a method that provides high stability to the material being wound even at high speeds.
The purpose is to provide a further improved device. In particular, the present invention is required to avoid certain problems inherent in wrapping corrugated tubes of plastic material.

For this purpose, there have heretofore been equipment suitable for use in conjunction with the low speed extrusion equipment for the production of plastic corrugated tubes described above.

However, as the speed of extrusion equipment has increased, the above-mentioned known equipment can no longer be used. In particular, it cannot be used where the coiled material has to be removed from the reel for packaging.

Problems that arise when coiling corrugated tubes (particularly plastic corrugated tubes) are that the corrugated tube material cannot slide along the material of the portion of the corrugated tube that is already coiled onto the reel. particularly occurs. This applies both when the wrapping material is placed closely adjacent to each other and when one layer to be wound is placed on top of another layer previously applied on the reel. In effect, the corrugated portions of the tube cause adjacent portions of the tube to appear hooked together.

A problem specific to plastic corrugated tubes increases as manufacturing and wrapping speeds increase, and the tendency of the wrapped material to flap increases considerably. That is, strong vibrations act in a direction transverse to the longitudinal axis of the material itself, taking the form of a somewhat standing wave between the point where the tube contacts the coil and the guide point fixed in advance on the device.

In order to obtain a tube package that can be handled mechanically, tight winding is important and the package must be fairly stable.

In this sense, the corrugated tube must be highly stable during the winding operation and must be precisely placed on the reel in order to preclude any subsequent sliding of the respective plastic material due to the corrugation. Must be.

The object of the invention is to provide a coil winding device which allows at all times sufficient support of the tube to be wound into coils in order to accurately guide and place the material to be wound onto the reel.

The purpose is to provide a coiling device as described at the beginning of the Detailed Description section, in which the guiding device extends tangentially with respect to the reel core and extends both radially and axially relative to the material to be wound. a rung member capable of applying a force, the rung member being disposed between the reel core or the material wound on the reel core and a substantially flat plate, which plate is also connected to the reel core; extending tangentially with respect to the reel core or the material on the core and extending across the width of the core and pivotable about an axis parallel to the axial direction of the core; a planer is movable in a radial direction away from the core under the action of a coiled material, and the crosspiece member traverses the plate in a direction parallel to the axis of the core; This is achieved according to the invention with a device characterized in that it is laterally slidable.

The advantages of the device according to the invention described above are not only that the individually wound materials are precisely positioned one next to the other on the reel;
The layers of the wrapped material are also placed tightly one on top of the other to provide a stable shaped package. The rung member is provided with material that is coiled up to the end of the coiled layer in order to place the next coiled layer while the member is guided in return movement. Automatically pushed sideways. This eliminates the need for special drives for the guide elements.

The device of the invention is further described in Swiss Patent Specification No.
618141, the reel core of which is composed of a plurality of movably supported parts each having a curved outer surface, the movable parts being able to move each of them in unison with said part. When placed in the outermost position of the reel, all the outer surfaces of the movable part together define the shape of a cylinder, which is pivotally supported on the stationary side of the reel and on the opposite side. pivotally connected to a member for radially drawing the end of the movable portion into the reel core on the opposite side for enclosing and releasing material in the radial direction of the reel; and the reel core further includes a plurality of pivotally supported rocker arms having a drive member that moves the rocker arms apart from each other to a radially oriented position. the movable portion of the reel core; It can have a device in communication with the member. If you do it like this,
The radial arms can be folded down for coil removal.

However, the above-mentioned Swiss patent specification no.
In view of the fact that in the device according to No. 618141, its swinging arms project almost the entire length of their arms in front of the normal front surface of the reel in their folded position, they It becomes an obstruction when the coil is removed and transported after being wound.

The present invention also provides improvements in this regard.
This includes a plurality of pivotably supported rocking arms that form one side of the reel in a radial position and are pivotably slidable along a central support shaft of the reel. Each of the swinging arms is pivotably connected to the movable portion of the reel core at a distance from the pivot of the arm such that the swinging arm can be retracted into the interior of the reel core. This is achieved by means of a device which is slidable through a guide member which is attached to the guide member.

In this way, the swinging arms are not only foldable, but also drawn into the interior space of the reel core. The arms are retracted to at least substantially the majority of their radial length, so long as their radial length is greater than or equal to the axial length of the reel.

The device of the present invention is further described in U.S. Pat.
27804421, with a guide bush or guide eye attached to the swinging arm and surrounding the material to be coiled and reciprocating relative to the reel core. Good too.

However, one embodiment of the device according to the invention provides that the guide bush is fitted with a parallel guide member cooperating with the rocking arm in order to maintain the axis of the guide bush in a direction extending tangentially to the reel. is included.

The prior art device described in the aforementioned U.S. Pat. No. 2,780,421 uses level winding.
In order to achieve winding, the swinging arm that carries the guide bushing, that is, the guide eye, is driven to operate reliably. It is designed so that it can swing freely.

The present invention will be explained below with reference to the accompanying drawings.

The device shown in the accompanying drawings consists of a platform 1 with a box-shaped frame 2, on which is mounted a device for driving two reels 3a and 3b. Reels 3a and 3b are arranged to operate alternately. That is, while material is being coiled onto one reel, the other reel, which supports a package of material that is already coiled, may be unwound when the entire package is removed from the reel. A band or cord is affixed to the package to hold the materials in close contact with each other. The reel is then ready to be operated again after the package has been formed on the other reel. In order to coil the corrugated tube, in particular the plastic corrugated tube, in the form of a package, a guiding device for coiling the material is provided on one of the reels 3a, 3b. According to the invention, this guide device is a composite guide device. One component of the guide device is adapted to place or release the material radially on the reel, and the other component surrounds or releases the material axially of the reel. It's becoming a matter of choice.

This composite guide device may include a pressing member 5 which extends tangentially to the reel core 4 and is pressed towards said reel core with a certain predetermined pressure, and the material is wound onto the reel core 4. The reel core can be moved by being pulled away from the reel core. The guide device may further be a horizontal bar member 5 extending tangentially to the reel core 4. This horizontal beam member 5
can be moved axially relative to the reel core 4 by a force exerted by the material wound into a coil. Such a force acts on the side surface of the horizontal bar member 5 arranged transversely to the axis of the reel core. In FIG. 3, when the crosspiece member 5 presses with one component on the material which is directly adjacent to the reel core 4 or already coiled on the reel in the position shown on the reel 3a; The material wound on the reel exerts a lateral force on the crosspiece member 5. This force moves the rungs 5 so that the wound material can be placed tightly next to each other on the reel. When one coiled layer is completed, the next material jumps across the rung member 5, temporarily removing the rung member 5, and then the wound material is placed on the reel in the opposite axial direction. and the material exerts a force on the other side of the crosspiece member 5.

The horizontal beam member 5 includes the reel core 4 or a material wound in a coil shape on the reel core and a plate 6.
The plate 6 extends tangentially to the coiled reel core 4 and has a width equal to the overall width of the reel core. The plate 6 is pivotally supported by a support indicated at 7 so that it can be swung away from the reel core 4 by the action of the coiled material. The horizontal beam member 5 is slidable along the plate 6, and its sliding resistance is adjustable. To this end, the crosspiece 5 is slidably mounted on the axle 10 by means of a bush 8 and an adjustable clamp 9. One end of the axle 10 is provided with a fixed abutment member 11 and the other end is provided with an adjustable abutment member 12. Therefore, the horizontal bar member 5 in the longitudinal direction of the reel core 4
The travel path of can be precisely adjusted to the position of the last wound material on the ends of the reel core. The horizontal member 5 is the collision member 11 or 12
As soon as the material to be coiled passes across the crosspiece 5 and successive layer formation begins on the other side of the crosspiece 5, Force is coming into play. The device according to the invention thus operates completely automatically, with the plate 6 tightly holding the previously wound material onto the reel core or onto the previously placed layer of wound material. have the effect of

The pressing force of the plate 6 and thus of the transverse member 5 is obtained by providing a counterweight 13 on the plate 6 on the other side of the pivot support 7. Said pivot support 7 is provided so that when the coiled material has to be removed from said reel, the plates 6 and rungs 5 can all be reeled out by pressing down on said reel, for example by means of a foot pedal. It can be removed from.
1 and 2 show the lowest position of the plate 6 with the crosspiece 5. FIG. Together the rungs 5 and the plates 6 form a composite guide for each of the reels 3a and 3b. The sliding resistance of the crosspiece 5 along the axle 10 can be adjusted by means of an adjustable clamp 9 in order to adapt the resistance to the elasticity or thickness of the material being coiled.

The above idea of the invention can also be embodied in the reels 3a and 3b employed in the novel device of the invention.

This means that the components of the composite guiding device for radially placing or releasing the material to be coiled onto the reel consist of a movably supported part 14 of the reel core 4 and also of the material being coiled onto the reel. It is implemented in such a way that the component for axially surrounding the is comprised of a pivotably supported rocker arm 15. These arms 15 are in the coil winding position (third
3b) or move away from each other to radial positions (see reel 3a in FIG. 3). arm 15
in the former position form an acute angle to the axis of the reel or extend parallel to the reel, and in the extended or radial position of the arm constitute the sides of the reel.

The reels 3a and 3b are also provided with a fixed arm 16, which constitutes a fixed side of the respective reel.

The device according to the invention is provided with arms 15 and 16 as sides or flanges and which allow the winding of a band or cord on the part of the package coiled on the reel so that it is not closed. Does not have a disc or wheel that has been removed.

A portion 14 of the reel core 4 is pivotally supported near the fixed side of the reel, as indicated by 17 (FIG. 2), and said portion 14 radially pulls a swingable arm 15. It is pivotally connected to a rod system 18 for loading.

Each portion 14 has a curved outer surface;
All of these outer surfaces together form a cylinder when the part occupies its outermost position (see reel 3a in FIG. 3). A rocking arm 15, pivoted at a position indicated by 19, is pivotally connected to a portion 21 of the central support shaft 20 of the reel.
, while each swing arm 15 is slidably passed through a pivotably arranged guide member 22 at a fixed distance from the pivot 19 . The guide member 2 of the swinging arm 15
2 has a pivot 23 at the pivotable end of the part 14.

When the package coiled on the reel 3a or 3b has to be removed from the reel, after wrapping another band or cord for holding the material wound around said package part, Part 21 is slid along shaft 20 from the position shown for reel 3a in FIG. 3 to the position shown in dotted lines in FIG.
This sliding operation can be performed in various ways, for example manually or by means of a slide bar located inside the shaft 20 and driven. A portion of the slide bar passes through a slot in the shaft 20 and cooperates with a section 21. Part 21
There is no need to explain the slide bar in detail since the manner of displacement of the slide bar does not form part of the scope of the invention. When displacing the portion 21 from its outermost position to its innermost position, the swinging arm 15 swings outward and is retracted into the interior of the reel core 4 as shown for the reel 3b in FIG. Ru. When the swinging arm 15 performs said displacement, the core portion 14 is compressed and thereby the reel core 4
forms an almost conical circumferential surface, so that the package can be easily removed from the reel core. Compression of the core portion 14 is due to the action of the package,
In particular, the swing arm 15, the guide member 22 and the bipot 1
This can be done through the cooperation of 9 people. When the parts 21 are moved to their outermost position, the rocking arms 15 can automatically reoccupy their radial position, so that the respective reel is ready to be used again. Complete.

The invention can also be used in equipment with two successively operating reels without interrupting the production or supply of material. According to the invention, the composite guiding device is a device 25 surrounding the material to be coiled and mounted on the rocking arm 24;
The reels 3a and 3b can be used alternately, since the device 25 can reciprocate with respect to the reel core 4 and axially displace the material near the reel in a position away from the reel core 4.

The feed material to be coiled into a tube, particularly a corrugated tube, and even a plastic corrugated tube type, is indicated by dashed lines 26 in FIG. The directionally enclosing device 25 is a guide bush, ie a guide eye, which can be swung together with a swiveling arm 24 in a plane perpendicular to the axis of the reel. Said oscillation is indicated by dashed lines 27 in FIGS. 1 and 3. The oscillating movement serves to position the starting point of the tube to be coiled close to the core of the reel, said starting point being fixed on the reel by a device not described in detail. After that, guide button 2
5 is placed in its original position so that the coiling operation of the material can begin. The correct position of the guide bushing 25 is ensured by a parallel guide member mounted on said guide bush and cooperating with a rocker arm for maintaining the axis of the guide bush 25 extending tangentially to the reel. Ru. There are various methods for maintaining the axis of the guide bushing 25 extending tangentially to the reel, but a preferred method is to attach it to the rotatable axle 28 of the guide bush 25, for example through a rocking arm 24. It can be configured with a gear wheel. A chain extending beyond the gear wheel is a non-rotatable axle 29 of the swing arm 24.
It is rotated around a fixed gear wheel. Since similar parallel guide members are generally known, the manner in which this gear wheel is used will not be described in detail.

When a tube to be coiled on a reel is moved axially relative to said reel, the tension of the substantially coiled material acting on the guide bushing 25 and the tube 26 exerts a braking force. The effect is that the direction of the coiled tube changes so quickly that the axial movement is reversed before the tube reaches one of the sides of the reel. In order to prevent the axial movement from being reversed before the tube reaches the side of the reel, the guide bushing 25 together with the rocking arm 24 is located at a distance from the reel in a plane extending parallel to the axis of the reel. It is now able to swing. This oscillation is indicated by arrow 30 in FIG. This oscillation is for example very slight in order to support the shaft 29 in the frame 2 on a horizontal transversely extending shaft and to balance it in its entirety to move the guide bush 25 in the direction of the arrow 30. Button 2 that guides lateral force
This can be done by simply acting on 5. A guide bush 25 is placed on the swinging arm 24.
The use of the oscillating arm 24 is centered between the two spaced reels 3a and 3b, and the guide bushing 25 is moved from the central position (FIG. 3) to one reel or the other. It is particularly suitable for the illustrated embodiment which is pivotable towards.

Although the present invention has been specifically described with respect to plastic corrugated tubes, which offer particularly significant advantages, the advantage in any case lies in the complete control over the manner in which the coiled package is wound. Because the perfect shape, structure and stability of the material is achieved, the invention can also be employed in coiling other elongated materials.
