Description

The invention relates to a winding core for Strapping means according to the preamble of claim 1.

In the unpublished DE-OS 41 38 800 in connection with a method and a device to avoid strapping related operations Breaks on machines for strapping packages an automatic, so-called "flying strapping tool telwechsel "provided such that two on the machine each from a strapping with a winding core existing strapping stock is available. While the strapping from one strapping telwick wrapped and processed by the machine the second supply of strapping is in Waiting position. So that when the current ver straps worked automatically from the waiting strapping stock can, the winding cores are the strapping one reflection each scanned by means of photocells area allocated. Now the one strapping is emptied telwickel, changes with regard to the Fo the cell's reflection behavior as soon as its beam is on  hits the reflection surface. When proceeding and counter state of the said patent application leads this outline End of funds notification for triggering various measures instructions in particular that the rest of the currently processed strapping from the Machine is pulled out and reversing means switched automatic strapping feeder of the ready-made strapping wrap.

Similar facilities are comparable Known purposes for bobbin tubes. This is how the DE- OS 24 03 732 a reflective covering, which can be done with the help of a optical-electronic shot sensor is scanned to an automatic bobbin after weaving a bobbin bring about change. At what wrapping condition the bobbin change is not explained in detail. The CH-PS 666 471 only describes the evaluation of one consisting of a few layers of yarn using egg nes reflection signal, which apparently shows through penetrated yarn layers. The result of one such monitoring of the winding condition of the bobbin is strongly of the translucent property of the wrap dependent, both on the material of the yarn and on the yarn-specific bobbin winding condition. This Factors cause the signals to be very different Generate messages. This is why many yarns the signal therefore appears too late or so early that the machine already shuts off if another be there is a substantial amount of yarn remaining, which is now too un usable committee.

Proceeding from this, the object of the invention is based on a particularly economical strapping agent need the outline for maximum operational safety of the material consuming the wrapping of the strapping enable machine.

The invention solves this problem by the features of claim 1. The invention thus teaches one, the strapping end identifier then and first to take effect if one for one further strapping of sufficiently long strapping means cut exists, and secondly, this in itself but no longer use the available section. On the one hand, this ensures that a Ma Line fault, for example, due to a package outline sufficient strapping remnants is closed and at the same time that only an optimized minimum length of strapping material remains. Aside from the cost aspect, the last is partly because of possible recycling problems from special advantage. As a strapping tool namely mostly thermally weldable plastic tape used.

Another front resulting from the invention part is that the strapping does not through needs to be visible or translucent to the end enable identification. So that can easily be outlined be used, which is made of plastic regenerate which is usually dark gray or black, is opaque in any case.

By designing the invention according to claim 3 meets the reflection surface support in the form of a right an extremely advantageous, new dual purpose. The US-PS 29 87 267 z. B. shows this only the fixation of the yarn end to one Spool of thread. The adhesive tape and the one it fixed The end of the yarn is outside in every operating condition of the wrap. Monitoring of the winding condition is not intended and would not even be possible.

For the rest, strapping has always been done middle ends on winding cores with self-adhesive labels without involving them in other tasks or in ir in a certain way on a strapping remnant align length.

The reflective surface can also be from an order Reflection color can be formed according to claim 5. This Order can for example consist of a along the Color stripe that extends throughout the core exist through which it is guaranteed with certainty that this reflection surface with the usual security stood from the actual end of the strap (or on the Covered core: released from the beginning of the strapping) will.

Further embodiments are in claims 6 marked to 9. With this arrangement, the photo sensory reflective surface itself not on the wrap core, but on the machine-side mandrel for the arranged. The advantage of this configuration is  essentially in that the support mandrel once with a Reflecting surface is to be provided and the strapping with telwickel only adapted to it with its winding core has a translucent window.

Another possibility within the scope of the invention The ability to recognize the end of the strapping results by the measure according to claim 10. In this case be the treatment withdraws to the end of the strapping not directly on the winding core, but on the strapping itself, but again on the his initial section near the winding core.

The invention is described below with reference to some of the Drawings of illustrated embodiments in detail NEN explained. Show in the drawings, each in egg A schematic diagram:

Fig. 1 shows a winding core with befindlichem it Restvor rat to strap and a core on the winding tape applied with reflect the outer surface,

Fig. 2 is a of FIG. 1 similar arrangement, except that the adhesive strip serves for fixing the Umreifungsmittelanfangs on the winding core,

3 shows an arrangement with a vapor onto the winding core mounted. Order from the reflection color,

Fig. 4 shows an arrangement with a translucent Fen in the winding core and a reflection sleeve on the mandrel carrying the winding core and

Fig. 5 shows an arrangement with a ver with reflection color strapping beginning section.

In all figures, a winding core with 10 and a winding residue 11 still thereon on Umreifungsmit tel 12 is shown. The length of this remaining strapping means 11 is dimensioned such that it could still be sufficient for complete strapping. This ensures that the not shown Umreifungsmit telabschnitt has been sufficient for the last previous strapping.

In the arrangement according to FIG. 1, a reflector 13 in the form of a self-adhesive strip with a reflective surface 14 is placed on the jacket of the winding core 10 . By pulling the strapping 12 from the winding core 10 , the reflective surface 14 is exposed, and it can be carried out by scanning by means of a photo cell ( 15 in Fig. 5) or the like. A machine command. The beginning of the strapping means 12 is located approximately in the longitudinal center of the winding core 10 . Therefore, the reflector 13 in the form of the reflective adhesive strip covers an axially central region of the winding core 10 , so that the winding residue 11 of strapping means 12 , which can be seen from the drawing, still remains on the winding core 10 after the strapping means has become end detection effective. Even when attaching the beginning of the strapping to one end of the winding core 10 , one would be able to arrange the reflective adhesive strips in the longitudinal center of the winding core 10 . Regardless of the location of the beginning of the strapping 11 , the reflective adhesive strip could of course also extend over the entire axial length of the winding core 10 , although it is of course sensible to keep this length low for cost reasons.

The embodiment of Fig. 2 differs from that of FIG. 1, in principle, in that here the reflectors gate 13 in the form of the adhesive tape with its reflec Governing surface 14 at the same time serves the strapping medium start to the winding core 10 to adhere. Here, the adhesive strip is arranged approximately in the longitudinal center of the winding core 10 to ensure that there is still a sufficient amount of strapping 12 on the winding core 10 be when the beginning of strapping is exposed by the overlying strapping winding.

Fig. 3 illustrates an order 16 of a reflection color, which is applied directly to the shell of the winding core 10 . In the illustration, an extending in the axial direction of the winding core 12 Farbstrei fen is shown. Of course, you could also arrange the area of the paint application similar to the adhesive strip shown in FIG. 1 or 2 or the jacket of the winding core 10 completely provided with reflection paint.

In FIG. 4, a reflective sheet 17 is arranged a sleeve on a support mandrel 18 of the winding core 10 in the form. So that the reflective surface of the film 17 can be detected by a sensor, the winding core 10 has a translucent window 19 in the form of a man breakthrough, which is slit-shaped here and extends over an area in the longitudinal center of the winding core 10 . Since a winding core 10 usually consists of cardboard, a simple punching can be carried out here.

Fig. 5 finally shows an arrangement in which the near-winding start portion of the strapping 12 itself is provided with a reflective layer, for example by coating this strapping portion with a reflective paint on or before immersing it on the winding core 10 . In this version, it is completely irrelevant at which point of the winding core of the strapping beginning at this BEFE Stigt because the entire strapping beginning section is ver seen in the necessary length with reflection color and is used immediately for scanning by the photo cell 15 .

For the reflectors 13 , a commercially available self-adhesive reflective material based on microprism base is preferably used, which is distinguished in particular by wide-angle reflective properties. The supporting mandrel sleeve 13 in the exemplary embodiment in FIG. 5 could also be made of this material because it is easily bendable and therefore clings to the supporting mandrel jacket very well.
