Description
The invention relates to an apparatus and a method for binding annular coiled material, the binding apparatus being arranged downstream of a cable winding device or being capable of being arranged downstream of such a device.
EP 1387449 Bl discloses an apparatus and a method for winding and binding cable-like conductor materials, e.g. optical waveguides. The upper region of a winding device has two recesses opposite one another. These have the purpose of enabling the finished coil to be gripped and raised by a unit in order then to be transported further or to transfer this coil to a binding unit. The coil is then passed over to a transfer carriage of an assembly system for further processing. The exact binding process is not mentioned. In general, however, long cable coils are still bound or fixed today by hand. Such a bandaging apparatus operating manually with adhesive tape is described, for example, in DE 10231765 Al. However, this bandaging apparatus is not suitable for annular coiled material.
It is therefore an object of the invention to provide an apparatus which can tie an annular coiled material directly at a cable winding device without it being necessary to remove the cable coil or to transport it or to subject it to another positional change beforehand, and to provide a method by means of which the binding process can be integrated in a synchronized, reliable and economical manner in the processing procedure of an automatic machine, e.g. of a CrimpCenter.
This object is achieved by the characterizing features of claims 1 and 13. Further developments of the invention are described in the sub claims.
The binding apparatus according to the invention has at least one binding device comprising
one or more moveable elements which have adhesive surfaces with a retaining means for an adhesive tape strip and at least one drive which is connected to the moveable elements via joints.
Also provided in the operating state is an adhesive tape strip which is temporarily held on its adhesive- free side by the retaining means of the adhesive surfaces and is positioned a distance away from the annular coiled material to be bound or a cable coil in a docking and waiting position. The formation of the moveable elements, adhesive surfaces and drives is such that the binding of the annular coiled material or of the cable coil is effected according to the invention in a fixing position, the annular coil material or the cable coil being present on the cable winding device in the rest position. The binding device on the other hand moves toward the annular coiled material or the cable coil 45, the adhesive surfaces advantageously guided on a circular path, with the adhesive tape strip fixed by them, moving towards one another until the adhesive side of the adhesive tape strip fixes and binds the annular coiled material or the cable coil all around.
The retaining means of the adhesive surfaces for the adhesive-free surface of the adhesive tape strips may be : suction nozzles introduced into the adhesive surfaces or forceps grippers arranged on the adhesive surfaces or adhesive acting temporarily on the adhesive surfaces or - means for electrostatic charging of the adhesive surfaces or other adhesive or retaining means or combination thereof .
According to the invention, the binding device additionally has an adhesive tape roll device having an adhesive tape roll rotatably mounted above the adhesive surfaces and an adhesive tape guide by which the adhesive tape end of the adhesive tape strip is guided. Moreover, according to the invention, a cutting knife device arranged below the adhesive tape roll device and above the binding device is provided for a fully automatic process, as well as a gripper arranged below the adhesive tape guide and moveable on a vertical guide from a first position to a second position. In the operating state, in a preparation position of the binding device, the gripper travels from a first position to a second position in the direction of the adhesive tape end of the adhesive tape strip. With opened gripper jaws, it grips the adhesive tape end and moves with the adhesive tape end back to its first position. After the exact positioning of the adhesive tape strip taken off from the adhesive tape roll in a defined length on the adhesive surfaces, the adhesive tape strip is cut off by the cutting knife device in a docking and waiting position. Approximately at the same time, the gripper jaws open again.
In the method according to the invention, an adhesive tape strip cut to a defined length is held exactly in position by upper adhesive surfaces and lower adhesive surfaces on its adhesive-free surface by a retaining means in a docking and waiting position of a binding device until the annular coil material or a cable coil is completely rolled up by a cable winding device. The binding device is then moved to a fixing position in the direction of the annular coiled material. The binding device is positioned between two winding arms of the cable winding device so that the coiled material to be bound is present centrally between pivot axes of the binding device immediately at or immediately before the outer surface of the annular coiled material or of the cable coil. The adhesive surfaces of the moveable elements are then swiveled on a circular path into the interior of the coiled material or of the cable coil. In this way, the adhesive surfaces of the adhesive tape strip touch one another and the coiled material or the cable coil is bound.
In a fully automatic variant of the invention, in a preparation position of the binding apparatus, a gripper is moved from a first gripper position vertically to a second gripper position. The free end of an adhesive tape strip held in position between an adhesive tape guide is gripped by the gripper jaws. By moving the gripper back to its first gripper position, the adhesive tape strip is taken off from an adhesive tape roll in a defined length, whereupon the binding apparatus is moved on the carriage to the docking and waiting position up to the adhesive-free back of the adhesive tape strip which has been pulled taut. There, the adhesive tape strip is temporarily held and fixed on the upper and the lower adhesive surfaces of the cable winding device by a retaining means for the adhesive tape strip, whereupon the adhesive tape strip is cut off below the adhesive tape guide by a cutting knife device. Approximately at the same time, the gripper jaws of the gripper are opened again and the free end of the adhesive tape strip is released. Thereafter, the binding process according to the invention is effected by the method according to the invention, according to claim 13 and according to the sub claims.
The invention is explained in more detail, figuratively and by way of example, with reference to the drawings.

The production of long, assembled, electrical cables, e.g. in a CrimpCenter, is a very complex process. Often, there are only one or two highly sensitive electrical contact elements at the end of a very long, heavy cable. To ensure that these contact elements are not damaged, automation of the work processes is essential. Only in this way can the failure rate be considerably reduced. In the working example according to Fig.l of a cable winding device 30, the applicant has therefore arranged a binding apparatus 60 downstream. In this working example, the binding apparatus 60 is docked in a modular manner to the cable winding device 30. It is also within the scope of the invention to integrate the binding device 60 according to the invention into a cable winding device 30. However, the modular design of individual apparatuses has the advantage that they can be exchanged without problems, for example for servicing. The binding apparatus 60 according to the invention is present in Fig.l in a preparation position 79. A carriage 88 which is arranged so as to be moveable along a central axis 89 in the direction of the cable coil 45 is present at the outermost right end on a support plate 87. A binding device 61 is arranged in the carriage 88. Said binding device has at least two moveable elements 62, 63 which have, in their outer end regions, adhesive surfaces 64, 64' having a retaining means for an adhesive tape strip. In this working example, the moveable elements are in the form of arms or pivot arms. The moveable elements 62, 63 of the binding device 61 are arranged pivotably mounted on pivot axis 66, 67. The adhesive surfaces 64, 64' should preferably be planar. Metal or plastic plates or plates comprising another hard-wearing material are suitable. Suitable retaining means for the adhesive- free surface of the adhesive tape strip 72 are the following:
suction nozzles 65, 65' introduced into the adhesive surfaces 64, 64' or forceps grippers arranged on the adhesive surfaces
64, 64' or - adhesive acting temporarily on the adhesive surfaces or means for electrostatic charging of the adhesive surfaces 64, 64' or other adhesives or retaining means or combinations thereof.
The binding device 61 furthermore has at least one drive 68 or 69, preferably two drives 68, 69, for example pneumatic cylinders, which are pivotably connected to the moveable elements 62, 63 via joints 70, 71. If only one drive 68 or 69 is used, the piston rod 93 or 94 thereof must be coupled to the moveable elements 62, 63 of the binding device 61 via two tooth systems or coupling rods or tension means (not shown) .
Four moveable elements 62, 63, two upper moveable elements 62 and two lower moveable elements 63, are preferably arranged in the binding device 61 according to the invention. In this working example, the moveable elements 62, 63 are each in the form of one- part arms which end in a curve at one of their ends. The two upper moveable elements 62 arranged parallel to one another are moveably guided at their curved end regions in two first pivot axes 66 in the housing wall of the carriage 88. At their other end, the moveable elements 62, 63 are bent at right angles in the direction of the cable winding device 30. The upper adhesive surface 64 is arranged between the right angled end regions of the two upper moveable elements 62. In this working example, plates 96 which have bores for receiving a shaft 95 which connects the two moveable elements 62 to one another are molded onto the upper, rear regions of the first two moveable elements 62. The shaft 95 engages the upper drive 68 and forms the first joint 70.
The two lower moveable elements 63 arranged parallel to one another are likewise guided in their curved end regions in two second pivot axes in the housing wall of the carriage 88. The moveable elements 63, too, are bent at right angles at their other end in the direction of the cable winding device 30. The lower adhesive surface 64' is arranged between the right angled end regions. The two second moveable elements 63 have plates 96 in the lower rear regions with bores for a shaft 95 which connects the two moveable elements 63 to one another. The shaft 95 in turn engages the lower drive 69 and forms the second joint 71.
The binding device 60 according to Fig.l additionally has :
an adhesive tape roll device 75 having an adhesive tape roll 76 rotatably mounted above the adhesive surfaces 64, 64' and an adhesive tape guide 77 by which the adhesive tape end 78 of the adhesive tape strip 71 is guided, a cutting knife device 80 arranged below the adhesive tape roll device 75 and above the binding device 61 and a gripper 84 arranged below the adhesive tape guide 77 and moveable on a vertical guide 81 from a first position 82 to a second position 83.
The gripper 84 with gripper jaws 85 travels to the preparation position 79 of the binding apparatus 60, from a first position 82 to a second position 83, in the direction of the adhesive tape end 78 of the adhesive tape strip 72. With the opened gripper jaws 85, it grips the free adhesive tape end 78 of an adhesive tape strip 72 positioned between an adhesive tape guide 77 and travels with the adhesive tape end 78 back to its first position 82, said gripper taking off an adhesive tape strip 72 in a defined or preselected length from an adhesive tape roll 76 and holding said adhesive tape strip in the tensioned state centrally and with its non-tacky surface a distance away from the adhesive surfaces 64, 64', in an exact position.
The invention is now to be explained in more detail with reference to a working example, in which suction nozzles 65, 65' which are introduced into the adhesive surfaces 64, 64' of plates by means of bores, are used for fixing the adhesive-free surface of the adhesive tape strip 72 to the adhesive surfaces 64, 64', and as shown in Fig.l to 5.
The suction nozzles 65, 65' of the adhesive surfaces 64, 64' are connected at one end via pneumatic tubes 86, 86' to a vacuum pump which generates reduced pressure.
An elastic material 90, 91, e.g. foam or cellular rubber, is arranged in each case below the suction nozzles 65, 65', in the direction of the central axis 89 and between the two upper moveable elements 62 and between the two lower moveable elements 63. In the present working example, the elastic material 90, 91 has a cuboid shape. Advantageously, however, it can also be adapted to the shape of the cable coil 45 to be bound, so that the pressure on the adhesive tape tab(s) forming during binding and on the cable coil 45 is distributed as uniformly as possible.
In Fig.2, the binding device 61 was moved on its carriage 88 arranged on the support plate 87, along the central axis 89 in the direction of the cable coil 45, to a docking and waiting position 73 up to the non- tacky back of the adhesive tape strip 72 which is pulled taut, where the suction nozzles 65, 65' of the binding device 61 engage the adhesive tape strip 72 by means of reduced pressure and fix said adhesive tape strip. In this position, the adhesive tape strip 72 is engaged by suction on its non-tacky surface by the suction nozzles 65, 65' and held a distance away from the annular coil material to be bound or from a cable coil 45.
After positioning of the adhesive tape strip 72 before the adhesive surfaces 64, 64' is complete, a signal generator triggers a pulse for separating the adhesive tape strip 72 from the adhesive tape roll 76 by the cutting knife means 80. Fig.3 shows that the adhesive tape strip 72 is cut off below the adhesive tape guide 77 by the cutting knife device 80 and approximately simultaneously the gripper jaws 85 of the gripper 84 are opened again, the free end of the adhesive tape strip 72 being released again. The gripper can be moved back to a rest position. The adhesive tape strip 72 cut to a defined length is now held exactly positioned exclusively by the upper suction nozzles 65 of the upper adhesive surface 64 and the lower suction nozzles 65' of the lower adhesive surface 64' on its non-tacky surface in the docking and waiting position 73 of the binding device 61 until the annular coiled material or a cable coil 45 has been completely wound by the cable winding device 30. It is within the scope of the invention that docking and waiting position 73 are not identical but that, after the docking of the adhesive tape strip 72, the binding device 61 is moved to a separate waiting position along the central axis 89. As soon as the cable winding device 30 has come to rest, the binding device 61 travels on the carriage 88 from the docking and waiting position 73 to a fixing position 74 in the direction of the annular coiled material or cable coil 45 according to Fig.4. In the fixing position 74, the binding device 61 is positioned between two winding arms 36 of the cable winding device 30 so that the cable coil 45 is present centrally between the pivot axes 66, 67 of the pivotable moveable elements 62, 63 of the binding device 61, directly at or directly before the outer surface of the annular coiled material or of the cable coil 45. By extension of the piston rods 93, 94 of the drive 68, 69, which piston rods are connected to the plates 96 of the moveable elements 62, 63, the adhesive surfaces 64, 64' arranged on the moveable elements 62, 63 are swiveled, according to Fig.5, on in each case an opposite circular path into the interior of the coiled material or of the cable coil 45 and are moved toward one another, until the adhesive surfaces of the adhesive tape strip 72 touch one another and connect to one another and completely surround the coiled material or the cable coil 45 in this way at the binding point, and the coiled material or the cable coil 45 is thus bound. It is advantageous if the adhesive surfaces 64, 64' are equipped with a smooth or uniformly, slightly roughened surface comprising metal or plastic and the adhesive surfaces 64, 64' rest flat against one another after the end of the process of pivoting out.
The pneumatic tubes 86, 86' arranged at the backs of the suction nozzles 65, 65' and firmly connected to a vacuum pump must have a sufficient length to avoid being torn off during the binding process. However, not only the adhesive surfaces 64, 64' but also the outer surfaces of the elastic materials 90, 91 connected to the moveable elements 62, 63 are pressed against one another on contact of the adhesive surfaces at the moment of binding and, on compression, form at least one adhesive tape tab.
The release of the adhesive tape strip 72 temporarily held on the adhesive surfaces 64, 64' by the retaining means is always effected immediately after the end of the binding process. If the retaining means consists of suction nozzles 65, 65' , the vacuum pump is switched off during the pressing process itself. If the retaining means consists of a forceps gripper arranged on the adhesive surfaces 64, 64', said gripper opens its gripper arms immediately after the end of the binding process and releases the adhesive tape strip 72. If the retaining means consists of a temporarily acting adhesive, this must be applied again to the outer surfaces of the adhesive surfaces 64, 64' after the end of the binding process.
If the retaining means is produced by electrostatic charging of the adhesive surfaces 64, 64', the adhesive surfaces must be discharged after the end of the binding process so that, when the moveable elements 62, 63 are drawn back, the resulting adhesive tape tab cannot become detached again.
The binding apparatus 60 has at least one stepping motor (not shown) with a sensor system which actuates the carriage 88 on the linear axis and ensures the exact positioning of the carriage 88 in the preparation position 79, the docking and/or waiting position 73, the fixing position 74 and optionally further positions .
Optionally, after the end of the binding process in the fixing position 74 or in a further position of the binding apparatus 60, which is present between the docking and waiting position 73 and the fixing position 74, the coiled material or the cable coil 45 and/or the adhesive tape tabs formed during binding can once again be gripped over by the moveable elements 62, 63 and pressed with the adhesive surfaces 64, 64' and/or the elastic materials 90, 91 once again uniformly around the cable coil 45 so that the adhesive tape strip 72 is pressed firmly onto the cable coil 45 without it being possible for the assembled cable to be damaged.
It is within the scope of the invention that the cable coil is bound in the same manner several times and at different points by partial further rotation of the cable winding device 30.
Multiple binding of a cable coil can also be achieved by connecting at least two binding apparatuses 60 to one cable winding device 30 each. This has the advantage of a constant production time compared with the singular bound cable coil 45.
The invention also comprises a binding apparatus having only one moveable element 62. In such an embodiment, the retaining surfaces 64, 64' are pivoted not through about 90° but through about 180° on the pivot axis 66. In this embodiment, the moveable element 63 is in the form of a rigid element having adhesive surfaces 64'. On pivoting of the moveable element 62 through 180°, the retaining surface 64 is pivoted into the interior of the coil material or of the cable coil 45 until the adhesive surfaces of the adhesive tape strip 72 touch one another and the coiled material or the cable coil 45 is bound.
After the end of the binding process, it is advantageous if the coiled material bound at least at one point with adhesive tape strip 72 or the cable coil 45 is received from a transport apparatus by pivoting of the winding arms 36 of the cable winding device 30, which are arranged on a winding disc 92, in the direction of their axis 37.
It is also advantageous if, for the purpose of traceability, each individual cable coil 45 is additionally automatically identified with an adhesively bondable label in the binding process or if each adhesive tape strip 72 used is inscribed immediately before or during the binding process according to the invention with a barcode by means of a printer or if an additional label is applied to the cable coil 45 immediately after the binding.
However, the invention is not limited by the description of the figures and claims. Rather, it also comprises embodiments which arise from combinations with the contents of the following patent applications filed on the same date: for the purpose of the combination of the device according to the invention or disclosed device, the patent applications filed on the same date are hereby stated (applicant's reference S75CH, S78CH and S79CH).
This combination is stated with regard to grounds for priority of any later combined application.
In relation to S75CH, there is the following possibility for combination:
The device for binding with a tape as in the present case is suitable in conjunction with a coil delivery apparatus according to the invention. The coiler described here can be engineered, for example, as in the case of that according to S75CH.
In relation to S79CH, there is the following possibility for combination:
A coiler having a transport apparatus according to S75CH can readily be equipped with a binding device described above. The advantageousness results in particular from the fact that well wound and optimally bound coils can be stored on a transport apparatus according to S75CH and can be delivered on to a further processing apparatus. In relation to S78CH, the present binder with the binding tape can, as a variant, be replaced by a binding apparatus according to S78CH, resulting in the following possibility for combination: A coiler which produces ends true to position, as in the application S79CH, is also suitable for fixing the produced coil by means of wire or tape according to S78. However, precisely a coil fixed in this manner in turn fits particularly well on a transport apparatus according to S75CH. The remaining design of the coiler can, for example, once again correspond to the embodiment shown here.
