[0003] Winding device for bandaging an elongated bundle of goods

[0004] The invention relates to a winding device for bandaging an elongated bundle of goods with a band, with a winding head, with a running ring rotatably mounted in the winding head, with a winding table attached to the running ring for supporting the bundle of goods, with a receptacle for a band roll for the band mounted in the running ring.

[0005] Bundled goods, such as cable harnesses or conductor harnesses, consist of individual electrical wires or hoses and are frequently used, for example, in motor vehicles.

[0006] Such a winding device is known, for example, from DE 20 2022 101 220 A1. In operation, the belt of the winding reel is guided by a conveyor drive via a deflection roller to a central recess in the winding table. When the bundled goods are being wound, the running ring is driven. The winding table and belt reel rotate around the bundled goods, so that the goods are wrapped with the belt.

[0007] In the automotive industry, however, wiring harnesses are often required that are wrapped with two different types of tape for their specific application. For example, PVC tape is needed for use in damp environments and textile tape for use in dry environments. Changing the tape requires downtime of the winding equipment and thus a long process run time. One could consider using two winding heads, each with adapted tape rolls. However, this would require a significant increase in the complexity of the winding equipment.

[0008] The invention is based on the problem of further developing a winding device of the type mentioned above in such a way that it is very convenient to use and simple to build.

[0009] This problem is solved according to the invention by the fact that the running ring has a second receptacle for a second belt roller.

[0010] This design means the winding device requires only a single winding head and is therefore particularly cost-effective. Furthermore, the winding device according to the invention significantly reduces the time required to change the tape, because the second tape is already available on the winding head. This also makes the winding device particularly user-friendly.

[0011] According to another advantageous embodiment of the invention, uniformly wrapping the bundled material with the respective band is particularly easy if the winding head has a conveyor drive for driving a band take-off aid. The conveyor drive ensures that the band is driven with a predetermined force and speed. Preferably, the tension of the band is detected by a load cell.

[0012] One could consider feeding the respective tape from the respective tape roll back to the changing table each time it is changed. However, according to another advantageous embodiment, the adhesive tapes can be selected directly at the changing table if the changing table has two recesses for each tape to be inserted.

[0013] According to another advantageous embodiment of the invention, the operation of the winding device when changing the bands for wrapping the bundled goods is particularly convenient if the winding head has an adjustment device for selecting the band to be wrapped.

[0014] According to another advantageous embodiment of the invention, further simplifying the operation of the winding device is achieved by arranging an adjusting lever of the adjusting device on the running ring. Preferably, the adjusting lever is pivotably mounted on the running ring. This makes the winding head particularly compact.

[0015] To ensure a uniform tension of the tape during winding, the recess containing the tape to be wound should be arranged in a working position in or near the center of the running ring. With two recesses in the winding table for two tapes, the tapes can be easily moved into their respective working positions according to another advantageous embodiment of the invention, provided that the adjustment device for moving the winding table with the respective recess into a working position in the center of the running ring is designed.

[0016] According to another advantageous embodiment of the invention, the use of the selected belts is particularly convenient if the adjusting lever is designed to select the connection of the conveyor drive with a belt take-up aid. According to another advantageous embodiment of the invention, the winding head is particularly simple if the adjusting lever has a drive wheel driven by the conveyor drive and if the drive wheel is selectively connected to one belt take-up aid or the other, depending on the position of the adjusting lever.

[0017] According to another advantageous embodiment of the invention, the winding head is designed to be particularly simple in construction if a cutting device is arranged on the winding table. Preferably, a single cutting blade of the cutting device is sufficient to cut both tapes.

[0018] According to another advantageous embodiment of the invention, uniform wrapping of the bundled material depending on its feed rate can be ensured if the winding table is arranged on the running ring in a way that allows for an adjustable inclination via a pendulum device.

[0019] Different cross-sections of the bundled material can be wrapped uniformly according to another advantageous embodiment of the invention if the winding table is connected to the running ring via a height adjustment device.

[0020] According to another advantageous embodiment of the invention, the movement of the end of the respective band into the center of the running ring is particularly simple if the winding table is guided longitudinally displaceably in the running ring.

[0021] The invention allows for numerous embodiments. To further illustrate its basic principle, two of these are shown in the drawing and described below. This shows in

[0022] Fig. l a winding device with a winding head ,

[0023] Fig. 2 shows a winding head of the winding device from Figure

[0024] 1 ,

[0025] Fig. 3 shows a rear view of the winding head.

[0026] Figure 2 ,

[0027] Fig. 4 shows the winding head from Figure 2 in a setting for the insertion of a first band.

[0028] Fig. 5 shows the winding head from Figure 2 in a setting for the insertion of a second band.

[0029] Figure 1 shows a wrapping device 1 for bandaging a bundled item 2. The bundled item 2 to be bandaged is shown as an example, with several sections 3 and various bands A, B with which the bundled item 2 is to be wrapped. Furthermore, the bundled item 2 has plug contacts 4 at its ends. The different bands A, B are shown in the drawing as dashed and dotted lines at the different sections 3. These different bands A, B can have different colors, different materials, or the like. Such different bands A, B are used, for example, for wet and dry applications or for special markings.

[0030] The winding device 1 has a linear hood 5, a winding head hood 6, and a process hood 7. The linear hood 5 covers a feed unit 8 for moving the bundled material 2. Below the winding head hood 6, a winding head 9 is arranged for wrapping the bundled material 2 with the two aforementioned bands A and B. The bundled material 2 is fed to the winding device 1 through a central opening 10 in the process hood 7. Furthermore, the winding device 1 has a control unit 11 for controlling its components, with a screen 12.

[0031] Figure 2 shows essential components of the winding head 9 of the winding device 1 from Figure 1 in a perspective view. The winding head 9 has a winding table 13 for supporting the bundled material 2 and a drive ring 14 rotatably driven about a central axis shown with dashed lines.

[0032] The winding table 13 is supported on the running ring 14 by a pendulum device 15 and guided longitudinally. The pendulum device 14 allows for an adjustable angle during the feed movement of the bundled material 2. A cutting device 16 for cutting the different strips A, B shown in Figure 1 is arranged on the winding table 13. The running ring 14 has two receptacles 17, 18 for strip rolls 19, 20 with the different strips A, B. The strips A, B are each guided by strip pull-off aids 21, 22 to a recess 23, 24 in the winding table 13.

[0033] An adjusting device 25 connects a conveyor drive

[0034] 26 optionally with one or the other tape trigger aid 21, 22. The adjusting device 25 has an adjusting lever.

[0035] 27 with a drive wheel 28 of the conveyor drive 26 mounted thereon. A detent device (not shown) holds the adjusting lever 27 in its set position. The drive wheel 28 is designed as a gear and is opposed to the output gears 29, 30 of the belt take-off aids 21, 22, which are also designed as gears. In addition, the adjusting lever 27 is mounted on the running ring 14 and is coupled to the longitudinally displaceable winding table 13. The coupling can be designed by a fork guide (not shown) or a driver 31 shown in Figure 3.

[0036] The running ring 14 is shown closed in the illustrated embodiment. In an embodiment not shown, the running ring can also be interrupted by an opening, as in DE 20 2022 101 220 Al openbart, and designed to be closed by a movable segment. Such open running rings allow the bundled material 2 to be inserted transversely to their axis of rotation.

[0037] Figure 3 shows a rear view of the essential components of the winding head 9 from Figure 2, when the winding table 13 has a height adjustment device 32. This allows the winding table 13 to be adjusted to move the axis of the bundled material 2 into the axis of rotation of the running ring 14. Furthermore, in the illustrated embodiment, the conveying drive 26 has a friction wheel 33, which is driven by the running ring 14 or an electric motor (not shown). Figure 3 also indicates the driver 31, which moves the winding table 13 in its longitudinal direction when the adjusting lever 27 is moved.

[0038] Figure 4 shows the winding head 9 from Figure 2 in a setting for wrapping the bundled material 2 with the single band A. The adjusting lever 27 is pivoted into a first end position and locked there, in which the single band take-up aid 21 is connected to the conveyor drive 26. Furthermore, the winding table 13 is moved into a position in which one of the recesses 23 is positioned in the area of ​​the axis of the winding head 9 (shown with a dashed line) and thus in the area of ​​the axis of rotation of the running ring 14. A longitudinal guide 34 of the winding table 23 is visible in this position. This allows the bundled material 2 shown in Figure 1 to be wrapped with the single band A.

[0039] Figure 5 shows the winding head 9 after the adjustment of the adjusting device 25 has been made to select the second belt B. The adjusting lever 27 is pivoted into a second end position and locked there, in which the other belt take-off aid 22 is connected to the conveyor drive 26. In addition, the winding table 13 is moved into a second position in which the other of the recesses 24 is moved into the central axis of the winding head 9, shown with a dashed line. This allows the bundled material 2 shown in Figure 1 to be wrapped with the other belt B.
