Description

Technical Field

[0001] The present invention relates to a cable winding device.

Background Art

[0002] Cables for connecting electrical components are commercially available in the form of cable rolls wound annularly in units of, for example, 200 m, and the cables wound as cable rolls are not aligned. When performing wiring work using a cable, a cable of a required length is manually pulled out from the cable roll placed on the floor or work table, cut, and wiring is performed using the cut cable. However, since the cables are likely to become entangled when the cable is pulled out from the cable roll, there is a problem that it takes time to untangle the cables every time the cables become entangled, resulting in a decrease in workability. Therefore, after winding the entire length of the cable around the winding drum by winding the cable from the purchased cable roll onto the winding drum once, the winding drum with the cable wound thereon is rotatably supported by a support base, and in that state, it is conceivable to smoothly pull out the cable from the winding drum. However, in this case as well, since the cable is manually pulled out from the cable roll, it still takes time to untangle the cables every time the cables become entangled, and some improvement is required. On the other hand, Patent Document 1 discloses a technique of winding a towing rope connected to the tip of a communication cable in alignment on the outer periphery of a drum when laying the communication cable on the ground or on a pole.

Summary of the Invention

[0004] The above-mentioned prior art merely discloses how to wind a tow rope onto a drum, and does not disclose how to smoothly wind the cable from a commercially available cable roll while suppressing entanglement and aligning it on the drum. This invention has been made in view of these circumstances, and its purpose is to provide a cable winding device that is advantageous in improving the efficiency of cable winding work by smoothly pulling out cables from commercially available cable rolls and winding them in alignment on a winding drum. [Means for solving the problem]

[0005] To achieve the above objective, one embodiment of the present invention is a cable winding device that winds a cable while aligning it in the width direction of a winding drum, comprising: a cable support section that rotatably supports a cable roll around which the cable is wound; a drive section for a winding drum that rotates the winding drum; and a cable moving section provided in a cable movement path from the cable support section to the winding drum, which moves the cable being wound onto the winding drum by the outer diameter of the cable in the width direction of the winding drum during one rotation of the winding drum, wherein the cable support section is provided with a tension mechanism that applies tension to the cable when the cable is pulled out from the outer circumference of the cable roll supported by the cable support section. Furthermore, one embodiment of the present invention is characterized by further comprising a guide roller provided between the winding drum and the cable moving section. Furthermore, in one embodiment of the present invention, the cable moving section is characterized by comprising: a guide shaft having a double helix groove formed thereon with a length equal to the overall width of the drum; a slider that supports the cable so as to be movable in its longitudinal direction and engages with the groove, causing the guide shaft to rotate, thereby moving back and forth linearly along the longitudinal direction of the guide shaft; and a drive unit for the cable moving section that rotates the guide shaft. Furthermore, in one embodiment of the present invention, the total width of the winding drum and the length of the guide shaft are W, the pitch of the grooves on the guide shaft is P, the grooves are formed for G rotations of the guide shaft, the outer diameter of the cable is C, and the rotational speed of the winding drum is D. Assuming that the slider moves by the outer diameter C of the cable per rotation of the winding drum, the pitch P of the groove is determined by the following formula (1). P = C / (G / D) (1) Furthermore, in one embodiment of the present invention, the drive unit for the cable moving section is composed of a motor, the motor and the drive unit for the winding drum are connected by a power transmission mechanism, the drive unit for the winding drum is composed of the motor, and the rotational speed of the guide shaft and the winding drum are the same. Furthermore, in one embodiment of the present invention, the drive unit for the cable moving section is composed of a motor, the motor and the drive unit for the winding drum are connected by a power transmission mechanism, the drive unit for the winding drum is composed of the motor, and the power transmission mechanism is provided with a transmission that can change the rotation speed of the guide shaft relative to the rotation speed of the drum in a stepless manner. Furthermore, in one embodiment of the present invention, the cable support portion comprises a base made of steel, a rotating plate made of steel rotatably disposed on the upper surface of the base while in contact with the upper surface of the base, a plurality of cable winding rods arranged on the upper surface of the rotating plate so as to be movable in synchronization with the radial direction of the rotating plate and around which the cable is wound, and a rotating plate support mechanism that rotatably supports the rotating plate, wherein when the cable is pulled out and the rotating plate is rotated, the weight of the rotating plate acts as resistance and applies tension to the cable, and the rotating plate constitutes the tension mechanism. [Effects of the Invention]

[0006] According to one embodiment of the present invention, a cable support section, a drive section for a winding drum that rotates a winding drum, and a cable moving section that moves the cable wound onto the winding drum by the outer diameter of the cable in the width direction of the winding drum during one rotation of the winding drum are provided, and a tension mechanism is provided on the cable support section that applies tension to the cable when the cable is pulled out from the outer circumference of the cable roll supported by the cable support section. Therefore, since the cable roll is rotatably supported by the cable support section, and tension is applied to the cable pulled out from the cable roll by the tension mechanism, problems such as cable entanglement are avoided, and the cable pulled out smoothly from the cable roll is aligned and wound onto the winding drum via the cable movement section, which is advantageous in improving the efficiency of cable winding work. Furthermore, by providing a guide roller between the winding drum and the cable moving section, even if the diameter of the cable being wound gradually increases, only the inclination angle of the cable between the winding drum and the guide roller changes, while the inclination angle of the cable between the guide roller and the cable guide remains constant. This simplifies the structure of the cable guide and is advantageous for smoothly winding the cable with the winding drum. Furthermore, if the cable moving section is configured with a guide shaft having a double helix groove formed to the same length as the entire width of the drum, a slider that supports the cable so as to be movable in its longitudinal direction and engages with the groove, causing the guide shaft to rotate and move back and forth linearly along the longitudinal direction of the guide shaft, and a drive unit for the cable moving section that rotates the guide shaft, it is advantageous in simplifying the configuration of the cable moving section while ensuring that the cable is reliably aligned and wound onto the winding drum, thereby improving the efficiency of the cable winding operation. Furthermore, if we let W be the total width of the winding drum and the length of the guide shaft, P be the pitch of the grooves on the guide shaft, the grooves are formed for G rotations of the guide shaft, C be the outer diameter of the cable, D be the number of rotations of the winding drum, and the slider moves by the outer diameter C of the cable per rotation of the winding drum, then determining the groove pitch P using the formula P = C / (G / D) (1) is advantageous for easily and reliably setting the groove pitch P. Furthermore, if the drive unit for the cable movement section is made of a motor, and the motor is connected to the drive unit for the winding drum by a power transmission mechanism, and the drive unit for the winding drum is made of a motor, and the rotational speed of the guide shaft and the winding drum are made the same, it is advantageous in simplifying the configuration of the power transmission mechanism. Furthermore, if the power transmission mechanism is equipped with a transmission that allows for stepless adjustment of the rotational speed of the guide shaft relative to the rotational speed of the winding drum, it becomes advantageous in easily handling situations where it is necessary to wind cables of different outer diameters onto the winding drum. Furthermore, if the weight of the rotating plate acts as resistance when the cable is pulled out and the rotating plate rotates, thereby applying tension to the cable and creating a tension mechanism with the rotating plate, it is advantageous for simplifying and compacting the tension mechanism.

[Figure 5] This is a cross-sectional view along line AA in Figure 4. [Figure 6] This is a view from arrow B in Figure 4. [Figure 7] This is a plan view of the lower rotating plate.

[0008] Hereinafter, embodiments of the present invention will be described with reference to the illustrations. As shown in Figures 1 and 2, the cable winding device 10 winds the cable 12 while aligning it in the width direction of the winding drum 14. The cable winding device 10 is composed of a frame 16, a cable support section 18, a tension mechanism 20, a winding drum 14, a drive section 22 for the winding drum, a cable moving section 24, and a plurality of guide rollers 26A, 26B, and 26C. The frame 16 is composed of a bottom frame 1602 formed from steel in a rectangular frame shape in plan view, four legs 1604 erected from the four corners of the bottom, an upper frame 1606 supported at the middle of each leg 1604 and formed from steel in a rectangular shape in plan view, and a pair of side plate frames 1608 erected from a pair of long sides of the upper frame 1606.

[0009] As shown in Figure 1, the cable support section 18 is located in the center of the bottom frame 1602. As shown in Figures 4 and 6, the cable support section 18 is composed of a rotating plate 28, a cable winding rod 30, and a rotating plate support mechanism 32. The bottom frame 1602 has a non-rotatable circular steel base 34 attached to its center. A rotating steel plate 28 is provided on top of this circular base 34. The rotating plate 28 comprises a lower rotating plate 36 and an upper rotating plate 38 that is superimposed on the lower rotating plate 36 and coupled to it so as to be rotatable together with the lower rotating plate 36. In this embodiment, the lower rotating plate 36 and the upper rotating plate 38 of the rotating plate 28 are formed with the same outer diameter. As shown in Figure 5, the lower rotating plate 36 is joined to the circular base 34 by a support shaft 3602 protruding from its lower surface, which is inserted into a bearing hole 3402. These support shafts 3602 and bearing hole 3402 constitute a rotating plate support mechanism 32 that rotatably supports the rotating plate 28. When the cable 12 is pulled out and the rotating plate 28 is rotated, the lower surface of the lower rotating plate 36 moves while contacting the upper surface of the circular base 34. Therefore, the weight of the rotating plate 28 acts as a resistance and applies tension to the cable 12. Thus, the rotating plate 28 constitutes the tension mechanism 20.

[0010] As shown in FIG. 6, the cable winding rod 30 includes a rod portion 3002 and a rod base portion 3004. As shown in FIG. 4, the cable winding rods 30 are arranged at equal intervals in the circumferential direction on a virtual circle 40 centered on the center of the rotating plate 28. As shown in FIGS. 4 and 6, the upper rotating plate 38 is provided with a plurality (six in the embodiment) of long grooves 3802 extending in the diameter direction at equal intervals in the circumferential direction. Further, the long grooves 3802 are provided so as to penetrate in the thickness direction of the upper rotating plate 38. Furthermore, as shown in FIG. 6, the upper rotating plate 38 has a screw groove 3804 formed at a location of the long groove 3802 near the lower surface. As shown in FIG. 7, the lower rotating plate 36 is provided with a plurality (six in the embodiment) of inclined long grooves 3604 extending in a direction intersecting the diameter direction at equal intervals in the circumferential direction. As shown in FIG. 6, the inclined long grooves 3604 are provided so as to penetrate in the thickness direction of the lower rotating plate 36. Also, as shown in FIG. 4, handles 42 are provided on the outer peripheral surfaces of the upper rotating plate 38 and the lower rotating plate 36, respectively (see FIG. 4).

[0011] As shown in FIG. 6, the rod base portion 3004 includes an upper base portion 3004A inserted into the long groove 3802 so as to be movable along the longitudinal direction of the long groove 3802, a lower base portion 3004B provided at the lower end of the upper base portion 3004A and inserted into the screw groove 3804 so as to be movable, and a rod pin 3004C protruding from the lower base portion 3004B and inserted into the inclined long groove 3604 so as to be movable. Therefore, as shown in FIG. 4, when the circumferential phases of the upper rotating plate 38 and the lower rotating plate 36 are shifted via the handle 42, the rod base portion 3004 is guided by the long groove 3802 and the inclined long groove 3604, and the diameter of the virtual circle 40 where the cable winding rods 30 are located is adjusted to expand or contract. Although not shown in the diagram, a click mechanism is provided on the lower surface of the upper rotating plate 38 and the upper surface of the lower rotating plate 36. Therefore, when the circumferential phase difference between the upper rotating plate 38 and the lower rotating plate 36 is shifted via the handle 42, the upper rotating plate 38 and the lower rotating plate 36 are locked and held in place at that shifted position. As shown in Figure 1, the cable roll 13 on which the purchased cable 12 is wound is placed on a rotating plate 28, and multiple cable winding rods 30 are inserted into its center. Then, the cable roll 13 shifts the circumferential phase between the upper rotating plate 38 and the lower rotating plate 36 via the handle 42, thereby increasing the diameter of the virtual circle 40. As a result, the cable roll 13 is adjusted to rotate integrally with the rotating plate 28.

[0012] As shown in Figure 2, the winding drum 14 is provided at one of the shorter sides and one of the longer sides of the upper frame 1606, which is formed in a rectangular shape in plan view. The winding drum 14 comprises a body portion 1402, flanges 1404 on both sides of the body portion 1402, and a drum support shaft 1406 that rotates integrally with the body portion 1402. The drum support shaft 1406 has the drum gear 44 mounted to it so that it can rotate as a whole. The drum gear 44 meshes with a first gear 46, which has the same shape as the drum gear 44. The first gear 46 has a second gear 48 mounted on the same axis. A chain 54 is stretched between this second gear 48 and a drive gear 50 attached to the output shaft of the motor 52, which constitutes the drive unit 64 for the cable movement section. In the figure, reference numeral 49 indicates a support wall erected from the upper frame 1606 and supporting the first gear 46 and the second gear 48. The second gear 48 and the drive gear 50 are identical in shape. In other words, the motor 52 and the winding drum 14 are connected by a power transmission mechanism consisting of a drum gear 44, a first gear 46, a second gear 48, a drive gear 50, and a chain 54. The drive unit 22 for the winding drum is composed of the motor 52. In this embodiment, the winding drum 14 and the guide shaft 56 are configured to rotate simultaneously by the motor 52.

[0013] As shown in Figure 2, the cable movement section 24 is provided at the other shorter side and the other longer side of the upper frame 1606, which is formed in a rectangular shape in plan view. In other words, the cable movement section 24 is provided in the cable movement path from the cable support section 18 to the winding drum 14. As shown in Figure 1, the cable 12, pulled out from the cable support section 18, reaches the cable moving section 24 via two rotatable guide rollers 26A and 26B. From the cable moving section 24, the cable 12 reaches the winding drum 14 via a rotatable guide roller 26C. The guide roller 26C is positioned at approximately the same height as the rotation center of the winding drum 14. As a result, the cable 12 that has passed through the cable movement section 24 is wound onto the winding drum 14 by passing under the guide roller 26C.

[0014] As shown in Figure 3, the cable movement section 24 is composed of a guide shaft 56, a slider 58, and a motor 52 (Figure 2). The guide shaft 56 has double helical grooves 5602 formed on its outer circumferential surface. A drive gear 50 is attached to one end of the guide shaft 56. The drive gear 50 is rotatable integrally with the guide shaft 56. The guide shaft 56 is covered by a cylindrical cover member 60, which is non-rotatably supported by the upper frame 1606. The cover member 60 is provided with a notch 6002 that exposes half of the circumferential portion along the entire longitudinal length of the helical groove 5602. The slider 58 is provided so as to be movable in the longitudinal direction of the cover member 60 but not movable in the circumferential direction of the cover member 60.

[0015] As shown in Figure 3, the slider 58 is provided with a cable guide 62 on its outer circumference. The cable 12 is movably inserted through the cable guide 62. The cable guide 62 changes the orientation of the cable 12 by approximately 90 degrees. The slider 58 has a rotatable hub 5802 mounted on its inner circumference. The hub 5802 engages with the helical groove 5602 through a notch 6002. Therefore, as the guide shaft 56 rotates, the piece 5802 is guided into the helical groove 5602. This causes the slider 58 to move back and forth linearly along the longitudinal direction of the guide shaft 56. The longitudinal dimension of the helical groove 5602 is approximately the same as the width of the body 1402 of the winding drum 14. The slider 58 is configured to move the position of the cable 12 in the width direction of the winding drum 14 by the outer diameter of the cable 12 while the winding drum 14 rotates once.

[0016] Furthermore, the spool 5802 is located at the end of the spiral groove 5602 with the cable 12 wound around the entire width of the body 1402 of the winding drum 14. Thereafter, the slider 58 moves in the opposite direction along the longitudinal direction of the guide shaft 56 as the guide shaft 56 rotates. The cable movement unit 24 only needs to move the position of the cable 12 by the outer diameter of the cable 12 during one rotation of the winding drum 14. For example, the guide shaft 56 may rotate once or twice during one rotation of the winding drum 14. In other words, the number of rotations of the guide shaft 56 does not need to be the same as the number of rotations of the winding drum 14. In this embodiment, the pitch of the spiral groove 5602 is formed to be the same as the outer diameter of the cable 12, and the winding drum 14 and the guide shaft 56 are made to rotate at the same rotational speed, or in other words, they are made to rotate once simultaneously.

[0017] Here, we will explain how to set the pitch of the helical groove 5602. Let W be the total width of the winding drum 14 and the length of the guide shaft 56. Let P be the pitch of the helical groove 5602 of the guide shaft 56. Assume that the helical groove 5602 of the guide shaft 56 is formed by the amount of G rotation of the guide shaft 56. Let C be the outer diameter of cable 12. Let D be the rotational speed of the winding drum 14. Assume that for each rotation of the winding drum 14, the slider 58 moves by the outer diameter C of the cable 12. The pitch P of the helical groove 5602 is determined by the following equation (1). P = C / (G / D) (1) This approach is advantageous for easily and reliably setting the pitch P of the helical groove 5602.

[0018] Next, we will explain the operation (usage) of the cable winding device 10. The worker inserts multiple cable winding rods 30 into the center of the purchased cable roll 13 and places the cable roll 13 on the rotating plate 28. Next, the operator shifts the circumferential phase of the upper rotating plate 38 and the lower rotating plate 36 via the handle 42 to expand the diameter of the virtual circle 40 where the multiple cable winding rods 30 are located, and presses the multiple cable winding rods 30 against the inner circumference of the cable roll 13, thereby causing the cable roll 13 and the rotating plate 28 to rotate together. Next, the worker guides the cable 12, which has been pulled out from the outer circumference of the cable roll 13, to the body 1402 of the winding drum 14 via guide rollers 14A, 14B, cable guide 62, and guide roller 14C, and attaches the end of the cable 12 to the body 1402. Then, the operator turns on the power to the motor 52. The motor 52 (winding drum drive unit 22) then rotates the winding drum 14 via the power transmission mechanism. As a result, the cable 12 is pulled out from the cable roll 13 while tension is applied at the cable support unit 18, and is wound onto the winding drum 14 via the cable movement unit 24. In this process, the slider 58, which is equipped with a cable guide 62, is moved back and forth linearly along the longitudinal direction of the guide shaft 56 by the rotation of the guide shaft 56 by the motor 52 (drive unit 64 for cable movement). As a result, the cable movement unit 24 moves the position of the cable 12 in the width direction of the winding drum 14 by the outer diameter of the cable 12 during one rotation of the winding drum 14. The cable 12 pulled out from the cable roll 13 is then wound up and aligned on the winding drum 14 by the operation of the cable moving unit 24. The operator disconnects the power to the motor 52 once all the cables 12 have been wound onto the winding drum 14. Then, the operator removes the winding drum 14 containing the wound cables 12 from the cable winding device 10, completing the series of operations. The removed winding drum 14 is then used for subsequent processes such as wiring.

[0019] The cable winding device 10 of this embodiment includes a cable support section 18 that rotatably supports a cable roll 13, a drive section 22 for a winding drum 14 that rotates the winding drum 14, and a cable moving section 24 that moves the cable 12 wound on the winding drum 14 in the width direction of the winding drum 14 by the outer diameter of the cable 12 during one rotation of the winding drum 14. The cable support section 18 is provided with a tension mechanism 20 that applies tension to the cable 12 when the cable 12 is pulled out from the outer circumference of the cable roll 13 supported by the cable support section. Therefore, since the cable roll 13 is rotatably supported by the cable support section 18, and tension is applied to the cable 12 pulled out from the cable roll 13 by the tension mechanism 20, problems such as the cable 12 becoming entangled are avoided, and the cable 12 pulled out smoothly from the cable roll 13 is aligned and wound onto the winding drum 14 via the cable movement section 24, which is advantageous in improving the efficiency of the cable winding work. Furthermore, when performing wiring work using the cable 12, the cable 12 can be smoothly pulled out from the winding drum 14 without getting tangled, which is advantageous in terms of improving the efficiency of wiring work.

[0020] Furthermore, as the cable 12 is wound up by the winding drum 14, the diameter over which the cable 12 is wound gradually becomes larger than the diameter of the drum body 1402, and the angle of the cable 12 with respect to the cable guide 62 increases. In this embodiment, since a guide roller 26C is provided between the winding drum 14 and the cable moving section 24, or in other words, between the winding drum 14 and the cable guide 62, even if the diameter of the cable 12 being wound up gradually increases, only the inclination angle of the cable 12 between the winding drum 14 and the guide roller 26C changes, and the inclination angle of the cable 12 between the guide roller 26C and the cable guide 62 remains constant. Therefore, by providing the guide roller 26C, the structure of the cable guide 62 can be simplified, and it is also advantageous for smoothly winding the cable 12 with the winding drum 14.

[0021] Furthermore, the cable movement unit 24 may be configured to move the cable 12 in the width direction of the winding drum 14 using an actuator such as a linear motor. However, as in this embodiment, if the cable moving section 24 is configured with a guide shaft 56 having a double helical spiral groove 5602 formed to be the same length as the entire width of the drum, a slider 58 that supports the cable 12 so as to be movable in its longitudinal direction and engages with the groove, causing the guide shaft 56 to rotate and move back and forth linearly along the longitudinal direction of the guide shaft 56, and a drive unit 64 for the cable moving section that rotates the guide shaft 56, it is advantageous in simplifying the configuration of the cable moving section 24 while ensuring that the cable 12 is reliably aligned and wound onto the winding drum 14, thereby improving the efficiency of the cable winding operation.

[0022] Furthermore, if the drive unit 64 for the cable movement section is configured with a motor 52, and the motor 52 and the drive unit 22 for the winding drum are connected by a power transmission mechanism, and the drive unit 22 for the winding drum is configured with a motor 52, then the rotational speeds of the guide shaft 56 and the winding drum 14 do not need to be different, as long as the cable 12 can be aligned and wound around the winding drum 14. However, as in this embodiment, if the rotational speeds of the guide shaft 56 and the winding drum 14 are the same, then gears of the same shape can be used for power transmission, which is advantageous in simplifying the power transmission mechanism.

[0023] Furthermore, as a tension mechanism 20 for applying tension to the cable 12 pulled out from the cable support section 18, various conventionally known mechanisms can be used, such as providing a tension roller around which the cable 12 is wrapped, and applying tension via this tension roller using a biasing member or weight. However, as in this embodiment, if the cable support section 18 is composed of a circular base 34 made of steel, a rotating plate 28 made of steel, a plurality of cable winding rods 30 around which the cable 12 is wound, and a rotating plate support mechanism 32 that rotatably supports the rotating plate 28, and when the cable 12 is pulled out and the rotating plate 28 is rotated, the weight of the rotating plate 28 acts as resistance and applies tension to the cable 12, so that the rotating plate 28 constitutes a tension mechanism 20, it is advantageous in simplifying and compacting the tension mechanism 20.

[0024] In this embodiment, the longitudinal dimension of the helical groove 5602 is provided to be approximately the same as the length of the body portion 1402 of the winding drum 14, and the cable moving portion 24 is configured to move the position of the cable 12 in the width direction of the winding drum 14 by the outer diameter of the cable 12 during one rotation of the winding drum 14. However, if the outer diameter of the cable 12 is twice that of the embodiment, the position of the cable 12 needs to be moved by two lengths along the width direction of the body 1402 of the winding drum 14 during one rotation of the winding drum 14, and therefore the guide shaft 56 needs to be rotated twice. In such cases, providing the power transmission mechanism with a transmission that can steplessly change the rotational speed of the guide shaft 56 relative to the rotational speed of the winding drum 14 is advantageous in easily handling situations where it becomes necessary to wind cables 12 of different outer diameters onto the winding drum 14.
