The present disclosure relates to a tool for dispensing a material about a bundle of elongate articles. More particularly, the present disclosure relates to a drive assembly and a motor assembly for a tool for dispensing the material about the bundle of elongate articles.
Generally, a tool can be used for automatically bundling elongate articles such as wires, cables, or the like. For example, such a tool can feed a material, such as a tape, about the bundled articles until the material overlaps itself, tensioning the material about the bundle of articles, and thereafter welding the material at the location of the overlap to provide a tensioned loop which secures the bundle of articles. The tensioned loop can then be cut free from the remaining stock of material so that the tool can be removed from the first bundle of articles and moved to a second location to secure a second portion of material about a second bundle of articles.
In some embodiments, a drive apparatus for a tool to bundle a plurality of elongate articles using a tape includes a drive assembly and a motor assembly. The drive assembly includes a guide block, a drive block, and a drive pin. The motor assembly includes a motor connected to the guide block of the drive assembly and a gear train connected to the motor and extending through the guide block of the drive assembly. The gear train includes a drive axle, a first gear, a second gear oriented to rotate around the drive axle, wherein the second gear is positioned to engage with the first gear, and a compliant member coupled to the second gear and oriented along the drive axle. The drive block of the drive assembly is driven by the second gear of the motor assembly via the drive pin to engage and move the tape through the tool in a first direction. The drive block of the drive assembly is driven by the second gear of the motor assembly via the compliant member to engage and move the tape through the tool in a second direction opposite the first direction.

In some embodiments, the spring element 248 can include any of a plurality of members including, but not limited to, a leaf spring, a coil spring, a torsion spring, a clip, other spring elements, and combinations thereof.
When the drive axle 232 engages the drive block 206 to cause the drive block 206 to move the tape through the tool 100 in a first direction, such as, but not limited to, a direction to feed the tape through the tool 100, the compliant member 402 is not engaged. In some embodiments, the second gear 228 is coupled to an output nut 404 by a direct drive pin 406. The output nut 404 is fixed to the drive axle 232 to rotate with the drive axle 232. That is, a direct drive pathway via the direct drive pin 406 couples the drive axle 232 and the second gear 228 to the drive block 206 to move the tape through the tool 100 in the first direction. The direct drive pin 406 engages an output nut tab 408 to directly drive the output nut 404 when the tape is moved through the tool 100. After the tape is moved through the tool 100, the compliant member 402 is engaged to move the tape in a second direction opposite the first direction, such as, but not limited to, a direction to retract the tape through the tool 100 for the bundling operation.
In some embodiments, the compliant member 402 applies torque to the output nut 404. The output nut 404 can drive the drive axle 232, and thus the drive block 206. When moving the tape through the tool 100 to tension the tape, the compliant member 402 can facilitate preventing impact loading on the tape by deforming when the tape is fully tensioned and thus stops movement through the tool 100. In some embodiments, when the tape is fully tensioned and stops movement, the compliant member 402 allows the second gear 228 to turn up to nearly one additional turn (e.g., substantially one additional turn but less than 360° rotation). During the nearly one additional turn of the second gear 228, the deformation of the compliant member 402 can increase the torque required for the first motor assembly 204 to turn, thus decoupling the load experienced by the first motor 212 and the tension in the tape. That is, by increasing the torque, the first motor assembly 204 can require additional time to complete the nearly one additional turn of the second gear 228, allowing the controller time to control the first motor 212 in applying the desired tension to the tape by the drive block 206 to facilitate gradual ramping up of the torque tensioning the tape.
In some embodiments, the output nut 404 can be fastened to an end of the drive axle 232 using a hexagonal keyway. It is to be appreciated that the fastening of the output nut 404 to the end of the drive axle 232 using the hexagonal keyway is not intended to be limited, and in various other embodiments, other fastening means can be used in accordance with the disclosure.
The terminology used herein is intended to describe embodiments and is not intended to be limiting. The terms “a,” “an,” and “the” include the plural forms as well, unless clearly indicated otherwise. The terms “comprises” and/or “comprising,” when used in this Specification, specify the presence of the stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or components.
It is to be understood that changes may be made in detail, especially in matters of the construction materials employed and the shape, size, and arrangement of parts without departing from the scope of the present disclosure. This Specification and the embodiments described are examples, with the true scope and spirit of the disclosure being indicated by the claims that follow.
