The motor 50 for driving the drive apparatus 48 and the motor 82 for driving the spool mounting and driving assembly 42 may, for example be embodied as a gear motor, a brushless DC servo motors, a Permanent Magnet DC (PMDC) motor an AC induction motor with modulated control signal and switches to control speed and direction of rotation, some combination thereof, or the like. In some embodiments, the motor 50 and/or motor 82 may include an on-board motor controller, which may control operation of the motors 50, 82, and which may form part of and/or interface with the apparatus 400 (e.g., the processing circuitry 410 and/or motor control module 418 of the apparatus 400) illustrated in and described with respect to
In use, the tailing end of the rope 22 which extends from the cable puller 26 is fed through the central passageway 56 of the guide 40 and wrapped around the spool 24. The motors 50, 82 are then actuated to cause the spool 24 to rotate and the guide 40 to linearly translate. As the spool 24 rotates and as the guide 40 linearly translates, the rope 22 is wound around the spool 24. Rotation of the spool 24 provides tension to pull the rope 22 off the tailing end of a capstan 58 of the cable puller 26. The rope 22 travels through the central passageway 56 of the guide 40 which guides the rope 22 to line neatly next to itself on the spool 24 as the guide 40 linearly translates relative to the support 46. The guide 40 can translate back and forth relative to the support 46. The motor control module 418 is configured to sense the speed of the motor 82 or motors 50, 82 and adjust the speed of the motor 82 or the motors 50, 82 to provide an appropriate level of tension on the rope 22.
Attention is invited to the rope auto spooler machine 20′ shown in
In this three-motor axis system, a capstan assembly 158 is additionally included. The capstan assembly 158 includes a capstan 160 rotatably mounted on an upstanding support 162 which is attached to the frame 36, and a motor 164 for driving the capstan 160. The capstan 160 has a rotational axis 160a. As shown, the support 162 extends from the frame 36 on the same side as where the spool 24 is mounted. The rope guide assembly 38 is between the capstan assembly and the spool mounting and driving assembly 42. The capstan 160 is spaced from the surface 44 of the frame 36. In an embodiment as shown in
The motor 164 for driving the capstan 160, may, for example be embodied as a gear motor, a brushless DC servo motor, a Permanent Magnet DC (PMDC) motor, an AC induction motor with modulated control signal and switches to control speed and direction of rotation, or the like. In some embodiments, the motor 164 may include an on-board motor controller, which may control operation of the motor 164, and which may form part of and/or interface with the apparatus 400 (e.g., the processing circuitry 410 and/or motor control module 418 of the apparatus 400) illustrated in and described with respect to
In use, the tailing end of the rope 22 which extends from the cable puller 26 is wrapped around the capstan 160, fed through the central passageway 56 of the guide 40 and wrapped around the spool 24. The motors 50, 82, 162 are then actuated to cause the capstan 160 to rotate, the guide 40 to linearly translate and the spool 24 to rotate. The drive apparatus 48 causes the guide 40 to linearly translate relative to the support 46 and relative to the capstan 160 and to the spool 24. As the capstan 160 and spool 24 rotate and as the guide 40 linearly translates, the rope 22 is wound around the spool 24. Rotation of the capstan 160 and spool 24 provides tension to pull the rope 22 off the tailing end of the capstan 58 of the cable puller 26. The rope 22 travels through the central passageway 56 of the guide 40 which guides the rope 22 to line neatly next to itself on the spool 24 as the guide 40 linearly translates relative to the second part 40 of the frame 36. The guide 40 can translate back and forth relative to the second part 40 of the frame 36. The motor 82 of the spool 24 pulls the rope 22 onto the spool 24. The motor control module 418 is configured to sense the speed of the motor 82 or motors 50, 82 and is configured to adjust the speed of the motor 82 or the motors 50, 82 to provide an appropriate level of tension on the rope 22. In addition, the motor control module 418 is configured to sense the speed of the motor 164 and is configured to adjust the speed of motor 164 to provide a predetermined tension in the rope 22 between the capstan 160 and the cable puller 26.
In operation, the rope auto spooler machine 20, 20′ may be positioned on the floor by resting the frame 36 on the floor.

In some example embodiments, the apparatus 400 may include processing circuitry 410 that is configurable to perform actions in accordance with one or more example embodiments disclosed herein. In this regard, the processing circuitry 410 may be configured to perform and/or control performance of one or more functionalities of the rope auto spooler machine 20, 20′, such as to energize and control operation of motors 54, 56 and motor 164, if provided, in accordance with various example embodiments. The processing circuitry 410 may be configured to perform data processing, application execution and/or other processing and management services according to one or more example embodiments. In embodiments in which one or more of motors 54, 56, 164 include an on-board motor controller, the processing circuitry 410 may comprise the on-board motor controller(s) and/or may be communicatively coupled with the on-board motor controller(s) to enable the processing circuitry 410 to communicate with and control operation of the motors 54, 56 and motor 164, if provided, in accordance with various example embodiments.
In some embodiments, the apparatus 400 or a portion(s) or component(s) thereof, such as the processing circuitry 410, may include one or more chipsets and/or other components that may be provided by integrated circuits.
In some example embodiments, the processing circuitry 410 may include a processor 412 and, in some embodiments, such as that illustrated in
The processor 412 may be embodied in a variety of forms. For example, the processor 412 may be embodied as various hardware-based processing means such as a microprocessor, a coprocessor, a controller or various other computing or processing devices including integrated circuits such as, for example, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), some combination thereof, or the like. Although illustrated as a single processor, it will be appreciated that the processor 412 may comprise a plurality of processors. The plurality of processors may be in operative communication with each other and may be collectively configured to perform one or more functionalities of the apparatus 400 as described herein. For example, in some embodiments in which the processor 412 comprises a plurality of processors, the plurality of processors may comprise one or more on-board motor controllers, such as may be implemented on the motors 54, 56 and/or 164 of some embodiments. In some example embodiments, the processor 412 may be configured to execute instructions that may be stored in the memory 414 or that may be otherwise accessible to the processor 412. As such, whether configured by hardware or by a combination of hardware and software, the processor 412 is capable of performing operations according to various embodiments while configured accordingly.
In some example embodiments, the memory 414 may include one or more memory devices. Memory 414 may include fixed and/or removable memory devices. In some embodiments, the memory 414 may provide a non-transitory computer-readable storage medium that may store computer program instructions that may be executed by the processor 412. In this regard, the memory 414 may be configured to store information, data, applications, instructions and/or the like for enabling the apparatus 400 to carry out various functions in accordance with one or more example embodiments. In some embodiments, the memory 414 may be in communication with one or more of the processor 412, the user interface 416, and the motor control module 418 via one or more buses for passing information among components of the apparatus 400.
The motor control module 418 may be embodied as various means, such as circuitry, hardware, a computer program product comprising a computer readable medium (for example, the memory 414) storing computer readable program instructions that are executable by a processing device (for example, the processor 412), or some combination thereof. In some embodiments, the processor 412 (or the processing circuitry 410) may include, or otherwise control the motor control module 418. The motor control module 418 may be configured to control the energization of the motor 82 and motor 164 if provided, so that the motor 82 and motor 164, if provided, spins the spool 24 and the capstan 160, if provided, at a level of rotation to provide an appropriate tension on the rope 22. The motor control module 418 may be configured to control the energization of the motor 50 of the guide 40 to move the guide 40 along its path to appropriately wind the rope 22 onto the spool 24. In some example embodiments, the motor control module 418 may be configured to control energization of one or more of motors 54, 56, and 164 based on input from one or more sensors, which may sense size and status information of the rope 22, as described further herein below.
The desired tension provided by the rope auto spooler machine 20, 20′ is dependent upon providing the proper tailing force to the cable puller 26. The inner diameter of the rope 22 and the type of rope 22 are limiting factors for the maximum tension to which the rope 22 can be subjected. The inner diameter of the rope 22 determines how many wraps of rope 22 can be placed on the spool 24 per revolution of the spool 24. In an embodiment, a user interface 416 may be provided and is in communication with the processor 412, memory 414, and/or motor control module 418. The user interface 416 may include any user interface element that may enable an operator to input information and/or that may be used to display operating status information to the operator. By way of non-limiting example, the user interface 416 may include one or more buttons, one or more switches, a keypad/keyboard, a display, a touch screen display, some combination thereof, or the like. An operator may use the user interface 416 to input information regarding rope type, rope diameter, spool size, etc. which information may be used by the motor control module 418 to control the energization of the motors 54, 56 and motor 164 if provided, so that the motors 54, 56 and motor 164 if provided, work in concert. The motor control module 418 may use an algorithm to determine the speed of movement of the guide 40 in relation to the speed of rotation of the spool 24 and the capstan 160, if provided. The motor control module 418 may be configured to access (e.g., from memory 414) a table or other structure which stores various profiles based on rope type, rope diameter, spool size, etc. and the motors 54, 56 and motor 164 if provided, may be controlled in accordance with the appropriate profile to maintain proper tension, appropriately level wind the rope, etc.
In some embodiments, the rope auto spooler machine 20, 20′ may include one or more sensors which may be configured to sense rope size/type information and/or status information (e.g., rope tension) for the rope 22. The sensor(s) may be communicatively coupled to the apparatus 400 (e.g., to the processor 412 and/or motor control module 418), and information received from a sensor(s) may be used by the motor control module 418 to control operation of one or more of motors 54, 56, 164. In an embodiment, a sensor 500, see
Other sensors (not shown) can be incorporated into the rope auto spooler machine 20, 20′. Such sensors may be in communication with the processor 412 to provide data inputs that may be used for controlling energization of the motors 54, 56 and motor 164, if provided, as described herein. For example, a limit switch type sensor may be provided to determine the end of travel for the guide 40; a linear displacement sensor may be provided to determine the outer diameter of the rope 22; a pressure sensor may be used to determine when the guide 40 is in the proper location with respect to rope 22 on the spool 24. Such a pressure sensor may be mounted on the guide 40. When the rope 22 is fed through the guide 40 and wrapped around the spool 24, when the guide 40 and the rope 22 are in the same plane, there will be no force exerted onto guide 40. This will allow the guide 40 to adjust its location to align with the location of the current wrap on the spool 24.
