Description

Technical Field

[0001] This invention relates to an automatic length cutting machine. Background Technology

[0002] For example, this automatic length cutter can be integrated into a modular cable processing center (WPC) for cable bundling.

[0003] For switchgear installation, cable handling centers can be used to transport, cut, mark, and crimp cables and wires using contact elements, such as end sleeves. The bundled cables are then typically bundled and housed in storage devices. Such centers are disclosed, for example, in US 8,442,664 B1. Actual cable bundling is performed by units implemented as specialized machines capable of carrying out pre-described work steps. These units have very complex structures and require considerable effort to adapt to different manufacturing tasks. Furthermore, such specialized machines are relatively expensive and require significant structural space within the production line.

[0004] A more flexible solution involves setting up modular units instead of dedicated machines, with workers performing the individual processing steps (cutting, marking, peeling, crimping, bundling) on ​​these modular units. Crimping is performed using a crimping machine, as known, for example, from the applicant's patent document DE 44 40 835 C1, and is used, for example, to press the wire end sleeves together with the peeled cable ends. In known solutions, these wire end sleeves are wound as a conveyor belt onto a drum and transferred from the drum to the crimping unit via a transport unit. Alternatively, the wire end sleeves or contact elements can also be housed separately in a memory and subsequently transferred to the crimping unit in a defined position via a suitable transport device. Such a transport device is described, for example, in DE 198 31 588 A1.

[0005] In known solutions, the end sleeve of the core wire to be crimped is placed onto the stripped cable end using a retaining unit, and then crimped via a crimping head. Stripping of the cable end can be done externally or via a stripping head integrated into the crimping machine.

[0006] For example, the structure of a transport unit for conveying end sleeves or other electrical components arranged on a drive belt is described in the applicant's printed document G 9308266.5. A similar transport unit is also disclosed in DE 19714964C1.

[0007] In mass production, it is necessary to crimp different cable cross-sections and electrical structural / contact elements together, and then install them in subsequent installation steps, such as when installing switchgear. In principle, there are two possibilities for this: in one variant, the crimping machine is modified to crimp different cable cross-sections and / or contact elements (core end sleeves), or multiple crimping machines are used to process different cable cross-sections / contact elements. The first-mentioned solution requires a long commissioning time and a large number of personnel. This drawback is overcome in the first-mentioned solution by using multiple crimping machines, but the investment cost is enormous.

[0008] Printed document DE 10 2004 057 818 B3 discloses a machine (implemented as a stripping machine, crimping machine) capable of processing different cable cross-sections and core end sleeves. Here, a drum and corresponding crimping device are provided for each type of core end sleeve, and they are equipped with a common driver that selectively engages with one of the crimping devices. This solution requires high equipment technology costs because multiple crimping devices must be provided and operated.

[0009] A crimping machine is disclosed in the applicant's patent DE 102015119217A1, which eliminates the aforementioned disadvantages. This crimping machine has a storage assembly with multiple drum cartridges, each assigned a common transport unit and a common crimping head, thus significantly reducing equipment technical costs compared to the solutions described above.

[0010] A crimping machine is disclosed in the applicant's later-published patent DE 102017118968, in which the contact element to be crimped is directly guided to the action area of ​​the peel or crimp joint without the need for an intermediate connecting supply device, etc. In this known solution, the contact element is preferably stored in a drum, so the crimping machine is accordingly implemented with a separation device.

[0011] Also based on the applicant's DE 10 2015 102 060 A1, a crimping machine is disclosed in which different core end sleeves are held in a memory assembly having multiple drums. Each of these drums is assigned a transport unit, via which pre-selected core end sleeves are transported to a transfer positioning. There, the separated core end sleeves are then guided to a common crimping head by means of a reciprocating transport vehicle.

[0012] This crimping machine is characterized by its high productivity. However, a certain drawback is that the required round-trip transport vehicle is relatively complex to construct and requires corresponding structural space, and therefore peeling cannot be achieved.

[0013] In the name The applicant provides a type of cable cutting machine suitable for cutting single and fine cables / lines with a cross-sectional area of ​​0.08 to 10 mm². In this known solution, the cable to be cut is transported to a predetermined rated length via a transport device with two frictionally engaged drive rollers, and then separated by a cutting device. The cable is conveyed from a cable storage, such as a cable roller, by a worker. The worker places the cable / line to be cut in an intermediate storage, retrieves the cut cable from the intermediate storage, and conveys it to a crimping machine, where the end sections of the cable are stripped and crimped using contact elements, such as core end sleeves.

[0014] Due to the high proportion of manual labor, the requirements for workers are relatively high when bundling cables, especially when laying cables in switch cabinets, and errors cannot be ruled out.

[0015] An automatic cable cutting machine is described in the applicant's DE 10 2018 131 444, in which the feeder is designed as a multi-feeder for multiple cable cross-sections or cable types, wherein the cables to be processed are aligned relative to the feeder or transport device of the automatic cable cutting machine via a control device. Here, the multi-feeder is implemented with an adjusting slider that can move, for example, laterally to the cable feed direction, so as to align the respective cables relative to the transport / cutting device.

[0016] The problem with this solution is that the respective cables must be precisely aligned relative to the transport / cutting device. Summary of the Invention

[0017] In contrast, the objective of this invention is to provide an automatic cable cutting machine in which cable delivery is reliably implemented with minimal equipment and technical costs.

[0018] This task is accomplished by the automatic length-cutting machine according to the present invention.

[0019] The automatic cable cutting machine according to the invention has a multi-feeder for multiple cable cross-sections or cable types, each of which is equipped with a transport device for feeding the cable according to a predetermined cable length and a cutting device for cutting the cable. The multi-feeder is arranged on an adjusting slider, which is preferably movable transversely to the cable feeding direction, wherein the cable to be processed is aligned with the transport device or the cutting device.

[0020] According to the present invention, the multi-feeder has a plurality of tubes or "whistles" that can be tilted and supported on an adjusting slider, each tube being matched with a cable cross-section and / or cable type, and each cable or line is guided in the tube. The tubes are supported on the adjusting slider so that the tubes can be selectively adjusted or tilted from an initial position to a working position by means of an actuation device, in which the cable guided in the tube is aligned with a transport device or a cutting device.

[0021] Therefore, at least one selected tube can be positioned relative to the transport or cutting device, enabling effective engagement of the cable guided therein with the transport or cutting device, while the other unmanipulated tubes remain positioned, preventing such effective engagement of their cables. By manipulating the tubes and their selectable positions into working positions, reliable guidance of the respective cables toward the transport / cutting device is ensured, thus eliminating malfunctions caused by incorrect relative positioning of the cable to be cut.

[0022] In a preferred improvement, the tubes can only be selectively manipulated individually by the operating device. In conceivable alternatives, at least two tubes can be selectively manipulated simultaneously by the operating device.

[0023] By using parallel arrangements of pipes, especially accordion-style pipes, the improved scheme ensures reliable guidance of each cable toward the transport / cutting device, thereby eliminating faults caused by incorrect relative positioning of the cable to be cut.

[0024] The tube can be implemented with an open or closed profile. Preferably, it is a tube with a circular cross-section (also known as a conduit).

[0025] In a particularly preferred embodiment of the invention, the tube is supported on a common inclined axis.

[0026] Tilting / pivoting becomes particularly simple when the operating section of the pipe, away from the transport or cutting device, extends beyond the tilting axis. The operating devices for tilting the respective pipes operate on this operating section.

[0027] In a possible embodiment, the operating device is implemented as a lifting cylinder, particularly as an electrically driven lifting cylinder, wherein the lifting cylinder is associated with all pipes.

[0028] Alternatively, the operating device can be implemented as an electric motor, especially a stepper motor, in which the motor is also associated with all tubes.

[0029] Regardless of the type of operating device, positioning the tube or "flute" to be operated into the operating area of ​​the operating device is achieved by moving the adjusting slider. For this movement, an actuator, linear actuator, or linear drive is provided.

[0030] The manipulation of the tube or "flute" is selectively performed via a control device.

[0031] In particular, the control device is positioned in a fixed orientation or is fixed relative to the housing.

[0032] If, in the improved design, the tube extends beyond the transport device at least in sections along the feed direction during its initial positioning, then the automatic length cutter is constructed to be particularly short.

[0033] To allow the conduit (which guides the cable to be cut) to tilt into the working position without collision, the improved design incorporates a repositionable, free-drawing zone for the transport device. During the working position, the conduit, particularly its entry section, extends into this zone, and the cable to be cut exits from the conduit.

[0034] In a preferred improvement, the pull-in area is defined on both sides by the peripheral surfaces of the rotatable feed rollers of the transport device. To improve effective cable engagement and clamping, the peripheral surfaces preferably have structured portions, such as ribs, corrugations, or protrusions extending transversely to the feed direction. The peripheral surfaces can have a simple cylindrical shape or a concave shape to improve cable guidance.

[0035] If the transport device has two movable, separate feed rollers, then the transfer of the respective cables to the transport device is particularly simple, as the cables are positioned between the feed rollers, especially in the pull-in area, by the inclination of their respective tubes / corresponding "whistles". Alternatively, one of the feed rollers is fixed in orientation, and only the other feed roller can move away from it.

[0036] Preferably, the two feed rollers are rotatable, and in particular, rotatable driven.

[0037] In an improved version of the first alternative, the two feed rollers used to clamp the cable in opposite directions can move relative to each other, especially laterally or perpendicularly to the feed direction; in the case of the second alternative, this is only one of the feed rollers.

[0038] In order to transport the cable to be cut to the cutting device in a controlled manner and quickly, the improved design includes a guiding device that extends between the entrance of the transport device and the cutting area of ​​the cutting device in a tubular, channel-like, or tunnel-like manner.

[0039] In order to remove the last cut cable from the cutting area of ​​the cutting device again, and to free the cutting device for cutting another cable, in the improved version, the feed roller of the transport device can be rotated and driven in the opposite direction of the feed direction.

[0040] When the cutting device is equipped with a transport slide, the removal of the cut cable is particularly easy.

[0041] In the improved design, multiple feeders, conveying devices, and / or cutting devices are covered by common or individual covers. This prevents disruption of the cutting process due to falling items or accidental interference, and in particular protects operators from injury. The covers are preferably transparent and, in particular, made of a non-fragile material. Therefore, the cutting process can be automated or well-monitored by operators, and initial visual inspection can be performed in the event of damage without removing the covers.

[0042] In the improved design, the automatic length cutter has an optical monitoring unit that detects at least multiple feeders, conveying devices, cutting devices, and / or conveying chutes from the field of view of the optical monitoring unit.

[0043] In order to allow the respective cables to pass through their respective matching tubes, in an improved version of each tube, the cover of the multi-feeder has a through recess, which is preferably constructed as an elongated hole to facilitate cable threading.

[0044] In order to achieve threading in a standardized and safe manner, it is preferable that threading occurs in the same position of the adjusting slider, preferably in the stop position or end position of the adjusting slider with respect to the adjusting direction.

[0045] Therefore, in the improved design, the through recess is arranged on a section of the cover of the multi-feeder, and the stop position or end position of the adjusting slider with respect to its adjustment direction is located below this section.

[0046] In the improved design, the multi-feeders, with or without operating mechanisms, are arranged as detachable or separate modules from the transport and cutting devices. In both cases—detachable or separate—this allows for the simple modular replacement of multi-feeders, for example, those differing in the number and / or diameter of tubes. Therefore, the same transport and cutting devices can be used for different cable length combinations, requiring only the replacement of the modularly adaptable multi-feeders.

[0047] In a possible improvement, fastening devices for a detachable single feeder are constructed or arranged in the working positioning section of the automatic length cutter, particularly in the aforementioned pull-in area. This allows for quick reversion to a single feeder, if necessary, and especially in modularly detachable multi-feeder designs.

[0048] Therefore, in the improved design, the automatic length cutter has a separate single feeder for detachable installation in the space section and at least one fastening device. Preferably, the modularly detachable multiple feeders are pre-installed, and the single feeder is included in the delivery range of the automatic length cutter.

[0049] According to the present invention, a method for cutting cables using an automatic cable cutter designed according to at least one aspect of the foregoing description comprises at least the following steps: selecting the cable to be cut by adjusting an adjustment slider such that a tube mated to the cable can be aligned relative to a transport device or a cutting device; and aligning the tube by tilting it from its initial position to its working position via an actuating device.

[0050] After cutting, the following steps are followed: transporting the predetermined length of cable section to the cutting device via a transport device; cutting the cable section via the cutting device; and especially exporting the cable section via a transport chute.

[0051] These steps can be repeated for the same or variable predetermined length.

[0052] If another cable needs to be cut longer, or simply returned to the neutral starting position of the automatic cable cutter, the method has the following steps: in particular, the last cut cable is pulled back via a transport device in the opposite direction of the feed; and the matching tube is tilted from the working position to the initial position via an actuation device.

[0053] If you want to cut another cable to a longer length, then perform the aforementioned steps for that cable: Select to Export.

[0054] The method according to the invention includes at least the steps described above: selecting a cable to be cut such that a tube mating with the cable can be aligned relative to a transport device or a cutting device; and aligning the tube by tilting it from its initial position to its working position.

[0055] Preferably, the above-described automatic length cutting machine has a control unit in which the method according to the invention is stored for implementation.

[0056] In a simplified embodiment, it is possible to have an automatic length cutter with a feeder having only one tube / flute-shaped component, which can be manipulated from an initial position to a working position by an actuating device, unlike the automatic length cutter presented herein. In this case, the tiltable support of the single tube / single flute-shaped component according to the invention need not be arranged on the adjusting slider according to the automatic length cutter described above, but can be arranged, for example, in an orientation-fixed or relative-to-the-housing-body fixed manner.

[0065] Figure 8 It shows that according to Figure 7 Enlarged view of the multi-feeder of the automatic length cutting machine. Detailed Implementation

[0066] Figure 1 A three-dimensional illustration of an automatic length cutter is shown, which can be used, for example, in a wire-processing center (WPC). Such a WPC is described in the prior art described above.

[0067] According to Figure 1The illustration shows an automatic length cutting machine 1, which only partially has the removed housing element. Therefore, the automatic length cutting machine 1 has a panel 2, on which, for example, is arranged a display 4, displaying the main processing parameters. The automatic length cutting machine 1 is operated, for example, via an IPC, which utilizes appropriate software for controlling the automatic length cutting machine 1 and other components of the WPC. According to... Figure 1 As illustrated, the automatic cable cutting machine 1 also has a multiple feeder 6, through which different cable cross-sections / types can be conveyed. Cable rollers are not shown; individual cables are arranged on the cable rollers and aligned relative to the multiple transport device 6. Cable transport is carried out via a transport device 8, through which the respective cables to be cut are conveyed to the cutting device 10. The transport device 8 is operated in such a way that the respective cables are cut to a predetermined length. In accordance with the invention, the cut cables are conveyed along a chute 12 to the next processing step, such as a crimping machine.

[0068] Figure 2 It shows that according to Figure 1 An enlarged view of the functional components of the automatic length cutting machine 1. As can be seen in this figure, the multiple feeder 6 is constructed with multiple tubes 14 arranged parallel to each other, the cross-sections of which are adapted to the respective cable cross-sections or respective cable types. The tubes 14 have the same length and are tiltably supported on the tilting shaft 16. In the illustrated embodiment, each tube 14 has a solid operating section 18 supported on the tilting shaft 16, and is tilted according to… Figure 2 In the illustration, it extends to the left beyond the tilt axis 16. The free end sections of tube 14 point toward the cutting device 10. Here, for example, the operating section 18 of tube 14 is configured such that these tubes 14 are loaded into the initial position shown based on the weight of the operating section 18, in which the end sections assigned to the cutting device 10 point upward. However, loading toward the initial position can also be achieved via a spring assembly, lever assembly, adjusting device, etc. From this initial position, one of the tubes 14 can be tilted by means of the lifting cylinder 20, so that the respective inlet of the tube 14 tilts downward, and accordingly, the cable guided in the tube 14 will be aligned relative to the cutting device 10. The relative positioning of the respective tubes 14 in the lateral direction (lateral to the transport direction) is achieved by means of a linear actuator or a linear drive 22, which is described in detail below. The linear drive acts on the adjusting slider 24, on which the tube 14 is supported by the tilt axis 16. In the illustrated embodiment, the multiple feeder is designed for thirteen cable cross-sections / cable types and correspondingly has thirteen tubes 14. Of course, the number of tubes 14 is not limited to 13, and the number of tubes 14 can be set according to the needs of each application.

[0069] In the described embodiment, each tube 14 is also provided with an inclined rod 26, which extends at parallel intervals relative to the respective tube 14.

[0070] The transport device 8, for example, implements two feed rollers 28 that can move apart to guide their respective cables and then merge to achieve effective engagement with their respective cables.

[0071] The transport device 8 causes individual cables of predetermined lengths to be pulled out from the rollers and then separated by the cutting device 10. The cutting device is implemented in a known manner with two cutting blades that can move relative to each other.

[0072] Figure 3 It shows the corresponding Figure 2 The view shows a linear actuator 22 with an adjustable slider 24 (see...). Figure 2 The section of the tilting rod 26 is covered by the housing cover 36, so that only the end section of the tilting rod 26 is visible. As can be seen in the figure, one of the tubes 14 tilts away from the column and tilts into its working position, in which its inlet is aligned with the two feed rollers 28 of the transport device 8.

[0073] According to Figures 1 to 3 The illustration also shows the covers 30 and 32 of the guide 34 between the slide 12 and the cutting device 10 and the transport device 8.

[0074] Figure 4 A schematic diagram of a multi-feeder 6 with a total of thirteen tubes 14 is shown, wherein one of the tubes 14, 14' (as already mentioned), is inclined downwards into a working position. It can also be clearly seen that the tubes 14 are implemented with different cross-sections to accommodate correspondingly different cable types / cross-sections. The tilting rod 26 is also clearly visible in the diagram as it tilts downwards along with the tube 14' located in the working position.

[0075] Of course, the number of tubes or flute-shaped parts may not be thirteen, but may be twelve or fourteen, depending on the specific application.

[0076] Figure 5 A view of a linear actuator 22 is shown. This linear actuator has a drive motor 38, specifically designed as an electric motor, which is connected to a lead screw 42 via a belt drive mechanism 40. A lead screw nut 44 is guided on the lead screw and is itself operatively connected to an adjusting slider 24. Therefore, the stroke of the lead screw nut 44 is directly transmitted to the adjusting slider 24. In the illustrated embodiment, each actuating section 18 of the feed tube 14 is equipped with a support spring 46. According to... Figure 5In order to tilt the tube 14 shown in the intermediate area to the working position, the operating section extending beyond the tilt axis 16 is correspondingly extended via the lifting cylinder 20 (according to...). Figure 5 (From the sixth position on the left) pivot upwards.

[0077] Figure 6 Finally, a bottom view of the multiple feeder 6, the conveying device 8, and the support 48 housing the cutting device 10 is shown (see below). Figure 2 The diagram shows the rotational drive 50 of the two feed rollers 28 of the transport device 8 and the drive 52 of the cutting device 10.

[0078] Figure 7 A second embodiment of the modular automatic length cutter 101 is shown. For simplicity, only the differences from the first embodiment will be discussed below. The modular multi-feeder 106 is configured for easy detachment and fastening to the base 7 of the carrying transport and cutting devices 8, 10 of the automatic length cutter 101. Figure 7 The disassembled state of the multi-feeder 106 removed from the base 7 is shown. To secure the modular multi-feeder 106 to the support 48, the support has two threaded holes 54 on its edge side. A through hole 56 is provided on the fastening flange 58 of the multi-feeder 106, allowing the fastening flange 58 to be fastened to the support 48 via a fastening screw (not shown).

[0079] As a supplement to the first embodiment, according to Figure 7 In this embodiment, the single feeder 60, constructed as a rigid conduit, is detachably pre-mounted on the support 48. It should be noted that this indicates the multiple feeder according to the invention can optionally be converted back to a rigid single feeder. Here, similar to the tubes 14' of the multiple feeders 6 and 106, which are respectively inclined into their working positions, the single feeder 60 leads to the pull-in area 62 of the transport device 8, which is laterally defined by the peripheral surface of the rotatably driven feed roller 28. By loosening the two screws 66 and the bridge 68 held thereby, the single feeder 60 is removable, freeing up structural space for the installation of the multiple feeder 106 as briefly described above.

[0080] Figure 8 The enlarged diagram shows the data based on... Figure 7The automatic length cutting machine 101 has a multiple feeder 106. The adjusting slider 24 is located in the middle position relative to its adjusting area. Here it can be seen that, unlike in the first embodiment, the housing cover 136 is implemented as transparent. On the other hand, a plurality of elongated through recesses 64 are formed in a region of the housing cover 136, which corresponds to one of the possible end positions of the adjusting slider 24 in the adjusting direction, and the through recesses are respectively associated with tubes 14 located at that end position. Therefore, it is possible to thread the respective cables into the associated tubes 14 via the through recesses 64. The lead screw 42 of the linear actuator for adjusting the adjusting slider 24 can also be clearly seen.

[0081] An automatic cable cutting machine with a multi-feeder is disclosed. The multi-feeder is designed to feed different cable cross-sections or cable types. The multi-feeder has multiple tubes, each corresponding to a cable cross-section / cable type, and is tiltably supported on an adjusting slider.
