[0003] Winding device for wrapping an elongated bundle of goods with a self-adhesive tape

[0004] The invention relates to a winding device for wrapping an elongated bundle of goods with a self-adhesive tape, with an application aid for applying the tape to the bundle of goods and with a rotation device for generating a relative rotation of the bundle of goods with respect to the application aid with the tape.

[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] Winding devices of the type mentioned above are known in practice in a wide variety of designs. The positioning aid guides the band against the bundled material. The positioning aid is then twisted with the band relative to the bundled material and moved along its length. In doing so, the bundled material is wrapped with the band in a spiral shape.

[0007] The positioning aid is designed to reliably press the strap against the bundled goods, ensuring a secure connection between the strap and the goods before any relative movement occurs. Otherwise, there is a risk that the strap will detach from the goods, especially at high relative speeds.

[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 enables a particularly reliable connection of the tape with the bundled material.

[0009] This problem is solved according to the invention by the fact that the positioning aid has a first arm, which protrudes from a base body in a basic position and supports the strap against the bundled goods, and a second arm, which lies in the base body in a basic position and is used to grasp the bundled goods from behind.

[0010] With this design, the first arm initially supports the belt against the bundled material being guided against the attachment aid. As the bundled material is pressed further against the first arm, thereby increasing the pressure on the belt, the second arm grasps the end of the belt and guides it around the bundled material. This ensures that the belt is guided around a large portion of the bundle's circumference and is very reliably attached to it. This design guarantees a reliable application of the belt to the bundled material. Thanks to the invention, no additional active actuators are required.

[0011] According to another advantageous embodiment of the invention, grasping the bundled material while moving it against the first arm is particularly easy if the second arm is coupled to the first arm in terms of movement.

[0012] According to another advantageous embodiment of the invention, the positioning aid is particularly simple in design if the two arms have a common bearing in the base body.

[0013] According to another advantageous embodiment of the invention, pressing the band against the bundled material over a large area of ​​the circumference is particularly easy if a receptacle between the arms has a size corresponding to the cross-section of the intended bundled material.

[0014] According to another advantageous embodiment of the invention, the intended contact pressure of the belt against the bundled material by the first arm can be ensured if both arms are pre-tensioned in their initial position. The pre-tension of the two arms is preferably generated by a spring element.

[0015] According to another advantageous embodiment of the invention, the band can be wound in a spiral shape over a predetermined length if the base body has a guide cheek for supporting the bundled material. The guide cheek enables reliable pressing of the band along the bundled material.

[0016] According to another advantageous embodiment of the invention, uniform pressing of the band against the bundled material is particularly easy if the first arm is curved from the bearing to the free end and points with the free end towards the intended direction of movement of the bundled material.

[0017] According to another advantageous embodiment of the invention, the positioning aid is particularly simple in design if the second arm has a crossbeam at its free end.

[0018] According to another advantageous embodiment of the invention, the bundled material is inserted into the positioning aid unimpeded by the second arm if the base body has a recess for receiving the second arm in its home position. According to another advantageous embodiment of the invention, the insertion of the bundled material into the positioning aid is further simplified if the positioning aid has an entry ramp for guiding the bundled material against the first arm.

[0019] According to another advantageous embodiment of the invention, the positioning aid can easily adapt to the bundled material if it is pivotably mounted parallel to the intended longitudinal axis of the bundled material and held in a predetermined position by a spring element. This is particularly advantageous for twisted or unevenly thick bundled materials because the position of the positioning aid is constantly adjusted to the bundled material. This also minimizes lateral stress on the bundled material.

[0020] According to another advantageous embodiment of the invention, a spiral wrapping of the bundled material is particularly easy if the application aid is connected with a longitudinal feed.

[0021] According to another advantageous embodiment of the invention, the positioning aid and a tape roll containing the tape supply can be simply arranged in a fixed position if the rotation device is designed to rotate the bundled material. This design allows the use of particularly large and easily replaceable tape rolls.

[0022] Winding devices typically have cutting devices that separate the tape after it has wrapped around the bundled goods. According to another advantageous embodiment of the invention, the remaining loose end of the tape can be reliably pressed against the bundled goods using the positioning aid, provided that a cutting device for separating the tape is positioned at a distance from the bundled goods. This design ensures that the tape end remains spaced from the bundled goods after wrapping. Upon a subsequent relative movement of the positioning aid around the bundled goods, the tape end is reliably pressed against the bundled goods.

[0023] 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

[0024] Fig. 1 a machine with a winding device for wrapping an elongated bundle of goods ,

[0025] Fig. 2 enlarges a sectional view through a part of the winding device from Figure 1 ,

[0026] Fig. 3 shows a perspective view of a section of the winding device during the wrapping of the elongated bundled material.

[0027] Fig. 4 - 7 shows an aid for attaching the winding device in various steps when attaching it to the elongated bundle of material.

[0028] Figure 1 shows a machine with a winding device 1 for wrapping an elongated bundle 2. Figure 2 shows an enlarged view of the winding device 1 in a cross-section through the bundle 2. The winding device 1 has a rotation device 3 for rotating the bundle 2 and a positioning aid 4 with a longitudinal feed 5 along the bundle 2. The positioning aid 4 also has a transverse feed 6 for its movement transversely to the bundle 2. A tape roll 7 for a self-adhesive tape 8, shown in Figure 3, is attached to the winding device 1.

[0029] The positioning aid 4 with adjacent areas of the winding device 1 is shown enlarged in a perspective view in Figure 3. The positioning aid 4 is shown in a basic position in which a first arm 9 protrudes and a second arm 10 lies flush in a base body 11. The base body 11 has a recess 13 for receiving the second arm 10 and a crossbeam 12 attached to it. The base body 11 also has a guide cheek 14. The base body 11 is pivotably mounted in the winding device 1 parallel to the longitudinal axis of the bundled material 2 and is held in its position by a spring element 15. An infeed ramp 16 faces the bundled material 2. A free end of the tape 8 rests on the infeed ramp 16, with one adhesive side of the tape 8 facing the bundled material 2. A cutting device 17 for separating the band 8 after wrapping the bundled material 2 is spaced apart from the positioning aid 4.

[0030] Figures 4 to 7 show individual steps in attaching the band 8 to the bundled goods 2. To simplify the drawing, only the attachment aid 4, the bundled goods 2 in cross-section, and the free end of the band 8 are shown.

[0031] Figure 4 shows the positioning aid 4 in its home position. The first arm 9 extends into the movement range of the bundled material 2 and is slightly bent. The second arm 10 is in a position lying within the base body 11. The two arms 9 and 10 define a receptacle 18, which essentially corresponds to the cross-section of the bundled material 2. Furthermore, the two arms 9 and 10 are coupled in their movement and mounted in a common bearing 19 within the base body 11. Thus, the two arms 9 and 10 form a rocker. The arms 9 and 10 are, for example, spring-loaded, magnetically biased, or held in the depicted home position by gravity.

[0032] First, the free end of the belt 8 is guided to the inlet ramp 16 of the mooring aid 4, as shown in Figure 4. In the illustrated basic position, the first arm 9 of the mooring aid 4 protrudes and the bundled material 2 is spaced apart from the belt 8 and the mooring aid 4.

[0033] Starting from the position shown in Figure 4, if the positioning aid 4 with the band 8 is moved against the bundled material 2 by means of the transverse feed 6 shown in Figure 2, the band 8 is initially pressed against the bundled material 2 by the first arm 9, as shown in Figure 5. The free end of the band 8 is still resting on the 4.

[0034] During a further movement of the positioning aid 4 against the bundled material 2, the second arm 10 presses the free end of the strap 8 against the bundled material 2, as shown in Figure 6. The two arms 9, 10 define a receptacle 18, which essentially corresponds to the cross-section of the bundled material 2.

[0035] After a further advance of the positioning aid 4, the bundled material 2 rests against the guide cheek 14 and the second arm 10 guides the free end of the strap 8 around the bundled material 2. This position is shown in Figure 7.

[0036] In the position shown in Figure 7, the band 8 is reliably connected to the bundled material 2. The bundled material 2 can then be rotated by the rotating device 3, and the longitudinal feed 5 moves the positioning aid 4 with the band 8 along the bundled material 2. The bundled material 2 is guided between the guide cheek 14 and the second arm 10, thereby connecting the band 8 to the bundled material 2. After wrapping, the band 8 is cut by the cutting device 17 shown in Figure 3, and the end of the band 8 is connected to the bundled material 2 by a further rotation of the bundled material 2.

[0037] Conversely, in another embodiment not shown, the positioning aid 4 can also rotate around the bundled material 2 with the belt roller 7. Furthermore, in another embodiment not shown, the positioning aid 4 can also be stationary and the bundled material 2 pressed against the positioning aid 4.
