[0001] The present invention relates to a reel device that performs winding or unwinding of a string-like body such as a cable or a hose by rotating a reel. [Background technology]

[0002] A reel device is known which includes a base, a rotatably supported winding drum having a circular outer peripheral surface in a cross section centered on the reel axis, which is the axis of rotation of the base, a reel which includes a flange (abutment portion) which also has a circular outer peripheral surface in a cross section centered on the reel axis and rotates integrally with the winding drum, and which unwinds a cable (string-like body) wound around the outer peripheral surface of the winding drum as the winding drum rotates, and a plurality of support units which support the reel from below and rotatably support it while floating above the top surface of the base, wherein the support units have rollers which are rotatably supported with the roller axes, which are axes parallel to the reel axis, as fulcrums, and further wherein the support units support the reel by abutting the outer peripheral surfaces of the rollers against the outer peripheral surfaces of the abutment portions (see, for example, Patent Document 1).

[0003] According to the reel device described in the above document, by moving the support unit to an appropriate position on the base, it is possible to rotatably support a variety of reels of different sizes and shapes on the spot. However, if the support unit including the roller is heavy, it can be difficult to move it as intended, and in some cases it can be difficult to position the support unit in the appropriate location on the base.

[Means for solving the problem]

[0006] In order to solve the above problems, a reel including a base, a rotatably supported winding drum portion having a circular outer peripheral surface in a cross section centered on the reel axis, which is the rotation axis of the reel, and a contact portion having an outer peripheral surface in a cross section centered on the reel axis and rotating integrally with the winding drum portion, wherein the reel winds a string-like body such as a cable or hose onto the outer peripheral surface of the winding drum portion by rotation of the winding drum portion, or unwinds the string-like body wound onto the outer peripheral surface side, a plurality of support units supporting the reel from below and rotatably supporting the reel in a state where it is lifted above the upper surface side of the base, and a cross section of the support units in a direction intersecting the reel axis. and a slide mechanism supporting the support unit on the upper surface of the base so as to be slidable back and forth in a direction perpendicular to the reel axis, wherein the support unit has a roller rotatably supported with a roller axis parallel to the reel axis as a fulcrum, and the support unit is configured such that, by sliding it to one side in the intersecting direction, the outer surface of the roller comes into contact with the outer surface of the abutment portion, thereby switching to a supportable state in which the reel can be supported, and by sliding it to the other side in the intersecting direction, the roller moves away from the reel and is switched to a non-supportable state in which the roller cannot provide support.

[0007] The support unit may have an actuator that drives the roller to rotate, and the support unit may be configured to transmit the rotational power of the roller to the reel when the support unit is switched to a supportable state and the roller is supporting the reel.

[0008] The slide mechanism may include a cross-direction side rail formed in the cross direction, and a cross-direction side slider that slides back and forth on the rail.

[0009] The contact portion may be a flange portion integrally formed on an end side of the winding drum portion.

[0010] When viewed from the direction of the reel axis, a pair of support units arranged on one side and the other side of the abutment portion may be provided as a support unit set, and when switched to the supportable state, the abutment portion may be clamped by the rollers of the pair of support units of the support unit set.

[0011] The support unit set may be provided for each pair of flanges, and the reel may be supported from below by four of the rollers when the support units are switched to the supportable state.

[0012] The support unit may include a lifting mechanism that raises and lowers the roller, and when switching to the supportable state, the lifting mechanism may be configured to switch between a grounded state in which the reel is grounded on the upper surface of the base and a non-grounded state in which the reel is supported by the roller and floats above the upper surface of the base.

[0013] The slide mechanism may be configured to support the support unit on the upper surface of the base so that it can slide back and forth in a switching direction that is a direction along the reel axis, and the roller may be configured to switch the support unit to an overlapping state in which it is positioned in a range that overlaps with the abutment portion when viewed from the intersecting direction by sliding the support unit to one side of the switching direction by the slide mechanism, and to a non-overlapping state in which it is positioned in a range that does not overlap with the abutment portion when viewed from the intersecting direction by sliding the support unit to the other side of the switching direction, and the support unit may be configured to be able to switch between the supportable state and the non-support state when switched to the overlapping state.

[0014] The support unit may be configured such that, when switched to the non-overlapping state, it is switched to a stored state in which the entire unit is positioned on the base in a planar view, and when switched to the overlapping state, it is switched to an expanded state in which at least a portion of it protrudes outward from the base in a planar view.

[0015] The slide mechanism may include a switching direction side rail formed in the switching direction, and a switching direction side slider that slides back and forth on the switching direction side rail.

[0016] The slide mechanism may be provided with a locking means for switching between a locked state in which the roller is locked in place by restricting the sliding of the roller by the slide mechanism, and a movable state in which the locked state is released and the roller is allowed to slide by the slide mechanism. [Effects of the Invention]

[0017] A slide mechanism is provided to support the support unit on the upper surface side of the base so that the support unit can slide back and forth in a direction crossing the reel axis, so that even if the support unit including the roller is heavy, the support unit can be easily moved as intended and placed at an appropriate location.

DETAILED DESCRIPTION OF THE INVENTION

[0019] 1 and 2 are a plan view and a side view of a reel device to which the present invention is applied. The reel device shown in the figures includes a base 1, a reel 2, a plurality of support units 3 that rotatably support the reel 2 on the upper surface side of the base 1, and a slide mechanism 4 that is provided for each of the plurality of support units 3 and slides the support unit 3 on the base 1.

[0020] The reel 2 is equipped with a reeling drum 7 that has a circular outer circumferential surface in a cross section centered on the reel axis 6, which is its imaginary horizontal axis of rotation, and that is cylindrical in the direction of the reel axis 6, and a pair of flanges 8, 8 (abutment portions) that are integrally formed on both ends of the reel axis 6 in the direction of the reel axis 6 of the reeling drum 7. Like the reeling drum 7, the flange 8 has an outer circumferential surface centered on the reel axis 6, and the outer circumferential surface is set to have a larger diameter than the outer circumferential surface of the reeling drum 7.

[0021] Incidentally, hereinafter, the direction parallel to the reel axis 6 is referred to as the "left-right direction," and the horizontal direction perpendicular to the reel axis 6 is referred to as the "front-rear direction."

[0022] Alternatively, a physical support shaft may be provided that passes through the center of the reel 2, and the axis of the support shaft may be set as the reel axis 6. In this case, the reel 2 is rotatably supported on the support shaft via a bearing.

[0023] The base 1 has a pair of left and right base constituent members 9, 9. Each base constituent member 9 has a pair of front and rear rectangular metal mounting plates 11, 11, and a connecting member 12 that connects the front and rear mounting plates 11. The base constituent members 9 are molded in a shape that is symmetrical from front to back. The left and right base constituent members 9, 9 are also molded in a shape that is symmetrical from left to right.

[0024] Each mounting plate 11 is detachably fixed to the bed of a truck or the like with fasteners such as bolts. Extension portions 13 are integrally formed on each mounting plate 11, extending toward each other. These extension portions 13 are located on the left and right outer edges of the mounting plate 11. The tips of the extension portions 13 of the front and rear mounting plates 11 are close to or abutting each other, so that their upper surfaces are flush with each other. The above-mentioned plate-shaped connecting member 12 is placed on the upper surfaces of the front and rear extension portions 13 in a range from one side to the other, and the connecting member 12 is fixed to the front and rear extension portions 13 with fasteners such as bolts, thereby connecting and fixing the front and rear mounting plates 11.

[0025] Next, the configuration of the slide mechanism 4 will be described with reference to FIGS.

[0026] The slide mechanism 4 has the above-mentioned mounting plate 11, a switching direction side table (switching direction side slider) 16 slidably supported on the mounting plate 11, and a cross-direction side table (cross-direction side slider) 17 slidably supported on the switching direction side table 16 and having a support unit 3 installed on its upper surface side.

[0027] The switching direction side table 16 is configured to slide back and forth in the switching direction by a pair of front and rear switching direction side rails 14a, 14a that are arranged at the front and rear ends of the upper surface of the mounting plate 11 and laid in the switching direction (left and right direction in this example), which is the direction along the reel axis 6 in a plan view.

[0028] The intersecting direction side table 17 is configured to slide back and forth in the intersecting direction by a pair of intersecting direction side rails 14b, 14b arranged on the left and right ends of the upper surface of the switching direction side table 16 and laid in the intersecting direction (in this example, the front-to-rear direction, which is the perpendicular direction) that intersects with the reel axis 6 in a plan view.

[0029] The pair of switching direction side rails 14a, 14a are formed in an inverted L shape extending in two directions, toward each other and downward, in a cross-sectional view, and are formed across the entire or nearly the entire width direction (left-right direction) of the mounting plate 11. The switching direction side rails 14a are detachably attached and fixed to the mounting plate 11 by a fixing device such as a bottle, with the lower end portion thereof entirely abutting against the upper surface of the mounting plate 11.

[0030] The switching direction side table 16 is a rectangular metal thick plate member that is elongated in the transverse direction, and its overall length corresponds to the distance between the pair of switching direction side rails 14a, 14a. The switching direction side table 16 is fitted between the pair of switching direction side rails 14a, 14a and supported so as to be slidable back and forth in the switching direction.

[0031] The pair of intersecting direction side rails 14b, 14b are formed in an inverted L shape extending in two directions, toward each other and downward, in a cross-sectional view, and are formed over the entire or almost entire length of the switching direction side table 16. The intersecting direction side rails 14b are detachably attached and fixed to the switching direction side table 16 by a fixing device such as a bolt, with the lower end portion thereof entirely abutting against the upper surface of the switching direction side table 16.

[0032] The transverse-direction table 17 is a rectangular metal thick plate member that is long in the transverse direction, and its width corresponds to the distance between the pair of transverse-direction rails 14b, 14b. The transverse-direction table 17 is fitted between the pair of transverse-direction rails 14b, 14b and supported so as to be slidable back and forth in the transverse direction.

[0033] According to the slide mechanism 4 having this configuration, the support unit 3 can be switched between a stored state in which the entire support unit 3 is located on the mounting plate 11 in a plan view and an expanded state in which at least a part of the support unit 3 protrudes outward from the mounting plate 11 in a plan view by the reciprocating sliding action of the switching direction side table 16 in the left-right direction. On the other hand, the support unit 3 is fixed to the upper surface side of the cross direction side table 17, and the support unit 3 moves in the front-rear direction by the reciprocating sliding action of the cross direction side table 17 in the front-rear direction.

[0034] Next, the configuration of the support unit 3 will be described with reference to FIGS.

[0035] Fig. 3 is a front view showing the main configuration of the support unit, Fig. 4(A) is a side view of the lifting mechanism showing the roller in the lowered state, Fig. 4(B) is a side view of the lifting mechanism showing the roller in the raised state, and Fig. 5 is a cross-sectional view of the main portion showing the state in which the sliding of the slide mechanism is restricted and the attachment configuration of the pipe receiver. Two of the multiple (specifically, four) support units 3 are arranged on one side and the other side of one flange 8 when viewed from the direction of the reel axis 6, constituting a set of support units. The remaining two support units 3, 3 are also arranged on one side and the other side of the other flange 8 when viewed from the direction of the reel axis 6, constituting a set of support units.

[0036] The support unit 3 comprises a unit base 18 fixed to the upper surface of the cross-direction side table 17 and formed in the shape of a square plate; a roller 19 which is cylindrical in a direction parallel to the reel axis 6 and abuts against the outer peripheral surface of the reel 2 (specifically, the outer peripheral surface of the flange portion 8) on its lower side; a support frame 21 which supports the roller 19 so that it can rotate around its axis; an electric motor (actuator) 22 which drives the roller 19 to rotate; a cylindrical side roller 23 which abuts against the end face of the reel 2 in the direction of the reel axis 6 when its outer peripheral surface is abutting against the roller 19, thereby restricting movement of the reel 2 in the direction of the reel axis 6; and an elevating mechanism 24 which raises and lowers the roller 19 and the side roller 23 together with the support frame 21.

[0037] The unit base 18 is detachably attached and fixed to the transverse direction side slide table 17 by fastening a plurality of points on its edge side to the transverse direction side slide table 17 with fasteners such as bolts.

[0038] The roller 19 is supported by the support frame 21 so as to be rotatable about its own axis, that is, a roller axis 27. Due to the above-mentioned configuration, this roller axis 27 is oriented in a direction parallel to the reel axis 6. Incidentally, the roller 19 is supported by the support frame 21 so as to be rotatable by a roller axis 28, which is a physical axis of rotation formed on the roller axis 27.

[0039] The support frame 21 has a pair of plate-shaped side frames 29, 30 that face each other in parallel with a predetermined gap in the direction of the roller axis 27, and a plurality of connecting rods 31, 32 that connect and fix the two side frames 29, 30 together.

[0040] One of the pair of side frames 29, 30 is a first side frame 29 formed in the shape of a diamond-shaped plate that is long in a direction perpendicular to the roller axis 27, and the other is a second side frame 30 whose lower edge has the same shape as the first side frame 29 over the entire length when viewed from the direction of the roller axis 27, and whose upper edge is molded in a shape that bulges upward in an arc shape above the first side frame 29.

[0041] In other words, the first side frame 29 is smaller than the second side frame 30, and the ends of the first and second side frames 29 and 30 in the overall length direction are formed in a range that coincides when viewed from the direction of the roller axis 27. The ends of the pair of side frames 29 and 30 in the overall length direction are connected and fixed to each other by a pair of connecting rods 31 and 32 that are oriented in a direction parallel to the roller axis 27.

[0042] An insertion hole 33 is formed in the lower part of the center of the second side frame 30 in the overall length direction, and a rectangular or approximately rectangular operating hole 34 is formed in the second side frame 30 in a part above the insertion hole 33. A bearing 36 is provided in the center of the first side frame 29 in the overall length direction, which rotatably supports the roller 19 with the roller axis 27 as a fulcrum.

[0043] Regarding the support structure of the roller 19, the roller 19 is positioned between a pair of side frames 29, 30, and with the roller shaft 28 inserted into the insertion hole 33, it is cantilevered and rotatably supported on the first side frame 29 by the above-mentioned bearing 36.

[0044] Furthermore, when the support unit 3 is switched to the above-described deployed state, the rollers 19 are switched to an overlapping state in which they are positioned in a range that overlaps with the flange portion 8 when viewed from the front-to-rear direction, whereas when the support unit 3 is switched to the above-described stored state, the rollers 19 are switched to a non-overlapping state in which they are positioned in a range that does not overlap with the flange portion 8 when viewed from the front-to-rear direction. That is, in this example, the deployed state is synonymous with the overlapping state, and the stored state is synonymous with the non-overlapping state.

[0045] The motor 22 is attached to and supported by the side frame 30 on the side that does not cantilever-support the roller 19, and is a geared motor having a drive shaft 42 that is coaxial or substantially coaxial with the roller shaft 28. The motor 22 is disposed on the side of the side frame 30 opposite the surface facing the other side frame 29. The motor 22 is remotely controlled by an operating unit (not shown). The drive shaft 42 is connected to the roller shaft 28 by a shaft coupling 43 so as to rotate integrally with the roller shaft 28.

[0046] The motor 22 is attached to and supported on the side frame 30 side by using one of the connecting rods 32 .

[0047] The side rollers 23 are supported on the support frame 21 side so as to be rotatable about their respective axes as fulcrums. The axes of the side rollers 23 are set so as to face in a direction along the radial direction of the circular end face when the side rollers 23 are in contact with a circular end face (specifically, the end face of the flange 8 opposite the winding drum 8) in the direction of the reel axis 6 of the reel 2, which is rotatably supported by rollers 19 provided for each of the plurality of support units 3. Specifically, for the rollers 19 and side rollers 23 supported by one support frame 21, the axes of the side rollers 23 face in the radial direction of the roller 19 when viewed in the axial direction of the roller 19.

[0048] Therefore, when the reel 2 is rotated by a plurality of rollers 19 (specifically, four rollers), the side roller 23 in contact with the end of the reel 2 also rotates around its axis as a fulcrum. Incidentally, this side roller 23 faces the reel 2 from the outside of the support frame 21 through the operating hole 34 of the second side frame 30.

[0049] The lifting mechanism 24 includes a support frame 21, a support member 38 that supports the support frame 21 on the unit base 18 side so that it can swing up and down around the end (specifically, connecting rod 31) of the support frame 21 closer to the reel axis 6 in the overall length direction (the overall length direction of the side frames 29, 30), and a hydraulic lifting actuator 39 that is interposed between the end (specifically, connecting rod 32) of the support frame 21 farther from the reel axis 6 in the overall length direction and the unit base 18 and that extends and retracts to drive the support frame 21 to swing up and down around the connecting rod 31 as a fulcrum.

[0050] The support member 38 is integrally provided to protrude upward from the unit base 18. The lifting actuator 39 is composed of a hydraulic cylinder or a hydraulic jack that expands and contracts. One end of the lifting actuator 39 is connected to a connecting member 41 fixed to the upper surface of the unit base 18 so as to be rotatable about the axis of a shaft portion 41a of the connecting member 41, and the other end is connected to the connecting rod 32 so as to be rotatable about the axis of the connecting rod 32.

[0051] The lifting mechanism 24 extends the lifting cylinder 39, causing the support frame 21 to swing upward around the connecting rod 32 as a fulcrum, thereby displacing the positions of the rollers 19 and side rollers 23 upward, while contracting the lifting cylinder 39 causes the support frame 21 to swing downward around the connecting rod 32 as a fulcrum, thereby displacing the positions of the rollers 19 and side rollers 23 downward.

[0052] Therefore, by displacing the rollers 19 upward with the lifting mechanism 24, the reel 2 is lifted while supported by the rollers 19, and is switched to a non-grounded state in which it is floating above the upper surface of the base 1. On the other hand, by displacing the rollers 19 downward with the lifting mechanism 24, the reel 2 is displaced downward together with the rollers 19, and is switched to a grounded state in which it is grounded on the upper surface of the base 1.

[0053] To explain the support structure for a single reel 2 using multiple (specifically, four) support units 3, 3, 3, 3, when the support unit 3 is switched to the unfolded state, it can be slid in the front-to-rear direction closer to the reel axis 6, causing the outer circumferential surface of the roller 19 to abut against the underside of the outer circumferential surface of the flange 8, switching it to a state (supportable state) in which it can support the reel 2. When the reel axis 6 and the roller axis 27 are parallel to each other, the flange 8 and the roller 19 are in a state in which their circular outer circumferential surfaces are in contact with each other when viewed in the axial direction of the reel 2 or roller 19.

[0054] When each of the pair of front and rear support units 3, 3, 3, 3 of the support unit set, which is individually provided for each corresponding left and right flange 8, 8, is switched to a supportable state, each of the left and right flanges 8, 8 is switched to a state in which it is clamped from below by a pair of front and rear rollers 19, 19, 19, 19 on both sides in the cross direction. Incidentally, to prevent the reel 2 from shifting as much as possible, it is desirable to slide each of the support units 3, 3, 3, 3 so that the four rollers 19, 19, 19, 19 contact the flanges 8, 8 at the same or nearly the same timing, and that the contact force is the same in the front, rear, left and right directions.

[0055] In this state, the rollers 19, 19, 19, 19 of all the support units 3, 3, 3, 3 are raised by their own lifting mechanisms 24, 24, 24, 24, to lift the reel 2 and switch it from a grounded state to a non-grounded state. In this case, too, it is desirable to drive the rollers 19, 19, 19, 19 upward in synchronization with one another.

[0056] The reel 2 switched to the non-grounded state is in a state in which it can be rotated by the rollers 19, 19, 19, 19. In other words, the non-grounded state is a state in which the reel 2 is rotatably supported on the upper surface side of the base 1.

[0057] On the other hand, in the non-grounded state, it is possible to return the reel 2 from the non-grounded state to the grounded state by lowering all of the support units 3 in unison with one another. Also, from this state, by sliding all of the support units 3 in unison with one another in a direction away from the reel axis 6, the contact between the outer circumferential surfaces of the rollers 19 and the outer circumferential surfaces of the corresponding flanges 8 is released, and the reel 2 is switched to a state (unsupported state) in which it is not supported by the four rollers 19.

[0058] Next, the configuration of the means for restricting the sliding of the sliding mechanism 4 will be described with reference to FIGS.

[0059] In addition to the above-described configuration, the slide mechanism 4 is equipped with a locking means 44 that restricts the sliding of the slide mechanism 4. The locking means 44 is composed of a positioning pin 46, a plurality of positioning holes 47 through which the positioning pin 46 is inserted, and a plurality of pin receivers 48 that fix the positioning pin 46. Note that in the illustrated example, the plurality of pin receivers 48 and the plurality of positioning holes 47 are omitted except for a few.

[0060] The positioning pin 46 is a metal locking member formed in the shape of a bolt, and its overall length (vertical length) is set to be the same or approximately the same as the sum of the vertical lengths (thicknesses) of at least the mounting plate 11, the switching direction side table 16, the cross direction side table 17, and the unit base 18 in a cross-sectional view.

[0061] The multiple positioning holes 47 are formed by aligning holes 47a, 47b, 47c drilled in the switching direction side table 16, the cross direction side table 17, and the unit base 18. The positioning holes 47 can be formed at multiple locations at predetermined intervals.

[0062] Meanwhile, pin receivers 48 are provided at a plurality of locations on the mounting plate 11 where positioning holes 47 can be formed. The pin receivers 48 are metal engaged members that are elliptical in plan view and convex in side cross section. The pin receivers 48 are embedded in the mounting plate 11 and fixed with fasteners such as bolts so that the top and bottom surfaces of the pin receivers 48 are flush with the top and bottom surfaces of the mounting plate 11 in side cross section.

[0063] The pin receiver 48 has a pin receiver hole 49 into which the tip end of the positioning pin 46 is threadedly engaged. This pin receiver hole 49 has a circular shape drilled toward the center in a plan view, and is arranged at a position overlapping with the positioning holes 47 when the above-mentioned multiple positioning holes 47 are arranged at positions overlapping with one another in a plan view.

[0064] By sliding the switching direction side table 16 and the cross direction side table 17 to their respective predetermined positions, the positions of the three holes 47a, 47b, and 47c in a plan view are aligned to form the positioning hole 47. This positioning hole 47 also coincides with the position of the pin receiving hole 49 in a plan view.

[0065] In this state, by inserting positioning pins 46 into the multiple positioning holes 47 and pin receiving holes 49 and threading and fastening their tips into the pin receiving holes 49, the slide mechanism 4 (specifically, the switching direction side table 16 and the intersecting direction side table 17) is switched to an locked state in which its sliding operation is restricted (prohibited). On the other hand, by releasing the threaded engagement of the positioning pins 46 and pulling the positioning pins 46 out of the positioning holes 47, the slide mechanism 4 is switched to a movable state in which its sliding operation is permitted.

[0066] Next, the configuration of the pipe receiver 51 will be described with reference to FIGS.

[0067] In addition to the above-mentioned configuration, the support unit 3 has a pipe receiver 52 for fixing a joint pipe 52 that connects one support unit 3 to another support unit 3.

[0068] The pipe receiver 51 has a mounting seat 53 that is detachably fixed to the upper surface of the unit base 18 with fasteners such as bolts, and a cylindrical insertion portion 54 that extends above the mounting seat 53 and extends in the left-right direction. The joint pipe 52 is a tubular member whose overall length (left-right length) is set to the length that extends from the pipe receiver 51 of one support unit 3 to the pipe receiver 51 of another support unit 3 that is arranged left-right relative to the support unit 3.

[0069] One end of the joint pipe 52 is inserted into the insertion portion 54 of one support unit 3, and the other end is inserted into the insertion portion 54 of the other support unit 3, and they are detachably fixed from above with fixing devices such as bolts. As a result, both support units 3, 3 connected to the joint pipe 52 are configured to be able to slide back and forth integrally in the front-to-rear direction.

[0070] According to the reel device configured as described above, a cross-direction side table 17 is provided that supports the support unit 3 on the upper surface side of the base 1 so that the support unit 3 can slide back and forth in the forward and backward directions. Therefore, even if the support unit 3 including the rollers 19 is heavy, it is easy to move the support unit 3 as intended and place it in the appropriate location. [Explanation of symbols]
