[Means for solving the problem]

[0006] To solve the above problems, the present invention provides a reel comprising: a base; a winding drum portion that is rotatably supported and has a circular outer surface in a cross-sectional view centered on the reel axis which is the axis of rotation of the winding drum; a contact portion that has an outer surface in a cross-sectional view centered on the reel axis and rotates integrally with the winding drum portion, wherein the winding drum portion rotates to wind a string-like body such as a cable or hose onto the outer surface side of the winding drum portion, or to unwind the string-like body wound onto the outer surface side, and a plurality of support units that support the reel from below and support it so that it can rotate while floating above the upper surface side of the base, and the support units in a direction intersecting the reel axis The support unit comprises a sliding mechanism that supports the upper surface of the base so as to be able to reciprocate and slide in the intersecting direction, the support unit having a roller that is rotatably supported with a roller axis which is an axis parallel to the reel axis as a pivot point, and further comprising a sliding mechanism that supports the upper surface of the base so as to be able to slide back and forth in the intersecting direction, the support unit having a roller that is able to rotatably support the reel by sliding the support unit to one side in the intersecting direction so as to bring the outer surface of the roller into contact with the outer surface of the contact part, and a non-supporting state in which the roller is separated from the reel and cannot support it by sliding the support unit to the other side in the intersecting direction. The support units are provided in pairs in the direction of the intersecting direction or the direction of the reel axis, and each is configured to be reciprocally slidable in a direction that moves closer to or further away from each other. It is characterized by the following.

[0007] multiple Support unit Each of The support unit may have an actuator that rotates the roller, and when switching to a supportable state and the roller is supporting the reel from below, the support unit may be configured to transmit the rotational power of the roller to the reel.

[0008] The sliding mechanism may include a rail on the intersecting direction side formed in the intersecting direction, and a slider on the intersecting direction side that slides back and forth along the rail.

[0009] The aforementioned contact portion is a flange portion integrally formed on the end side of the winding drum portion. Furthermore, a pair of the support units, each positioned on one side and the other side of the contact portion when viewed from the direction of the reel axis, are provided as a support unit set, and when switching to the supportable state, the contact portion is held between the rollers of the pair of support units in the support unit set. It may be considered as such.

[0010] The support unit has side rollers that contact the end face of the reel in the direction of the reel axis, thereby restricting the reel from moving in the direction of the reel axis. It may be considered as such.

[0011] A pair of flanges are integrally formed on both ends of the aforementioned winding drum portion, The support unit set may be provided for each of the pair of flanges, and the reel may be supported from below by the four rollers when the support unit is switched to the supportable state.

[0012] multiple Support unit Each of The structure may include a lifting mechanism for raising and lowering the roller, and when switching to the supportable state, the lifting mechanism may switch between a grounded state in which the reel is in contact with the upper surface of the base and an ungrounded state in which it is supported from below by the roller and floats above the upper surface of the base.

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

[0014] The support unit may be configured to be switched to a storage state in which the entire unit is positioned on the base in plan view by switching to the non-overlapping state, and to be switched to a deployed state in which at least a part of the unit protrudes outward from the base in plan view by switching to the overlapping state.

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

[0016] The slide mechanism may be provided with locking means for switching between a locked state in which the slide of the roller is restricted by the slide mechanism to lock the roller in place and a movable state in which the locked state is released to allow the slide of the roller by the slide mechanism.

Advantages of the Invention

[0017] Since a slide mechanism is provided to support the support unit on the upper surface side of the base so as to be reciprocally slidable in a direction intersecting the reel axis, even when the support unit including the roller is a heavy object, it becomes easy to move the support unit as intended and place it at an appropriate location.

Embodiments for Carrying Out the Invention

[0019] FIG. 1 and FIG. 2 are a plan view and a side view of a reel device to which the present invention is applied. In the illustrated reel device, there are 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 provided for each of the plurality of support units 3 and configured to slide the support unit 3 on the base 1.

[0020] The above-mentioned reel 2 has an outer peripheral surface that is circular in a cross-sectional view centered on a reel axis 6, which is a virtual and horizontal rotation axis, and has a cylindrical winding portion 7 in the direction of the reel axis 6, and a pair of flange portions 8, 8 (contact portions) integrally formed on both ends of the winding portion 7 in the direction of the reel axis 6. The flange portion 8 has an outer peripheral surface centered on the reel axis 6 similar to the winding portion 7, and the diameter of the outer peripheral surface is set to be longer than that of the outer peripheral surface of the winding portion 7.

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

[0022] In addition, a physical support shaft penetrating the central portion of the reel 2 may be provided, and the axis of the support shaft may be used as the above-mentioned reel axis 6. In this case, the reel 2 is rotatably supported by the support shaft via a bearing.

[0023] The above-mentioned 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 mounting plates 11, 11 made of metal formed in a rectangular shape, and a connecting member 12 connecting the front and rear mounting plates 11. The base constituent member 9 is formed in a front-rear symmetric shape. Further, the left and right base constituent members 9, 9 are formed in a left-right symmetric shape.

[0024] Each mounting plate 11 is detachably fixed to the truck bed or the like with fasteners such as bolts. Each mounting plate 11 has an integrally formed extension portion 13 that extends toward each other. This extension portion 13 is located on the left and right outer edges of the mounting plate 11. The tips of the extension portions 13, 13 of the front and rear mounting plates 11, 11 are close together or touching, and their upper surfaces are flush with each other. The aforementioned connecting member 12, which is formed in the shape of a plate, is placed on the upper surface of the front and rear extension portions 13, 13, from one to the other, and the front and rear mounting plates 11, 11 are connected and fixed by fixing this connecting member 12 to the front and rear extension portions 13, 13 with fasteners such as bolts.

[0025] Next, the configuration of the slide mechanism 4 will be explained based on Figures 1 and 2.

[0026] The sliding mechanism 4 includes the aforementioned mounting plate 11, a switching direction side table (switching direction side slider) 16 slidably supported on the mounting plate 11, and a crossing direction side table (crossing direction side slider) 17 slidably supported on the switching direction side table 16 and having a support unit 3 installed on its upper surface.

[0027] The switching direction side table 16 is configured to reciprocate and slide in the switching direction by a pair of front and rear switching direction side rails 14a, 14a, which are positioned 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 aligned with 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 left and right intersecting-direction side rails 14b, 14b that are positioned at 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-back direction which is perpendicular to 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 in a cross-sectional view: towards each other and downwards, and are formed over the entire or substantially entire width (left-right direction) of the mounting plate 11. The lower end of each switching direction side rail 14a is in overall contact with the upper surface of the mounting plate 11, and is detachably attached and fixed to the mounting plate 11 by fasteners such as bottles.

[0030] The switching direction side table 16 is a rectangular metal plate member that is elongated in the intersecting direction, and its total length corresponds to the distance between the pair of switching direction side rails 14a, 14a. The switching direction side table 16 is supported so as to be able to reciprocate and slide in the switching direction while fitted between the pair of switching direction side rails 14a, 14a.

[0031] The pair of intersecting rails 14b, 14b are formed in an inverted L-shape, extending in two directions in a cross-sectional view: towards each other and downwards, and extend over the entire or substantially entire length of the switching direction table 16. The lower ends of these intersecting rails 14b are in overall contact with the upper surface of the switching direction table 16, and are detachably attached and fixed to the switching direction table 16 by fasteners such as bottles.

[0032] The intersecting-direction side table 17 is a rectangular metal plate member that is elongated in the intersecting direction, and its width corresponds to the distance between the pair of intersecting-direction side rails 14b, 14b. The intersecting-direction side table 17 is supported so as to be able to reciprocate and slide in the intersecting direction while fitted between the pair of intersecting-direction side rails 14b, 14b.

[0033] According to the sliding mechanism 4 of this configuration, the support unit 3 is configured to switch between a stored state in which the entire unit is located on the mounting plate 11 in a plan view, and an extended state in which at least a part of the unit protrudes outward from the mounting plate 11 in a plan view, by the reciprocating sliding operation 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 of the cross direction side table 17, and the support unit 3 moves in the front-rear direction by the reciprocating sliding operation of the table 17 in the front-rear direction.

[0034] Next, the configuration of the support unit 3 will be explained based on Figures 1 to 5.

[0035] Figure 3 is a front view showing the main components of the support unit, Figure 4(A) is a side view of the lifting mechanism showing the roller in the lowered position, (B) is a side view of the lifting mechanism showing the roller in the raised position, and Figure 5 is a cross-sectional view of the main components showing the state in which the slide mechanism is restricted and the mounting configuration of the pipe support. 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 to form 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 to form 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 molded into a rectangular plate shape; a roller 19 that is cylindrical in a direction parallel to the reel axis 6 and abuts the outer circumferential surface of the reel 2 (specifically, the outer circumferential surface of the flange portion 8) on its lower side; a support frame 21 that supports the roller 19 so as to be rotatable around its axis; an electric motor (actuator) 22 that rotates the roller 19; a cylindrical side roller 23 that abuts the end face of the reel 2 in the direction of the reel axis 6 when its outer circumferential surface is in contact with the roller 19, thereby restricting the movement of the reel 2 in the direction of the reel axis 6; and a lifting mechanism 24 that 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 to the intersecting-direction-side slide table 17 by fixing multiple points on its edge to the intersecting-direction-side slide table 17 with fasteners such as bolts.

[0038] The roller 19 is rotatably supported on the support frame 21, with its own axis, the roller axis 27, as the pivot point. This roller axis 27 is oriented parallel to the reel axis 6 by the configuration described above. Incidentally, the roller 19 is rotatably supported on the support frame 21 by the roller axis 28, which is a physical axis of rotation formed on the roller axis 27.

[0039] The support frame 21 includes a pair of plate-shaped side frames 29, 30 that are parallel to each other and spaced apart 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 long, rhomboid plate perpendicular to the roller axis 27, and the other is a second side frame 30 formed in the shape of the first side frame 29, with the lower edge having the same shape as the first side frame 29 along its entire length when viewed from the direction of the roller axis 27, and the upper edge bulging out 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 both sides in the overall length direction are formed in a range that coincides when viewed from the direction of the roller axis 27. The respective ends of this pair of side frames 29 and 30 in the overall length direction are individually connected and fixed by a pair of connecting rods 31 and 32 oriented in a direction parallel to the roller axis 27.

[0042] An insertion hole 33 is drilled in the lower part of the center of the second side frame 30 in the overall length direction, and a rectangular or substantially rectangular operating hole 34 is drilled in the part of the second side frame 30 above the insertion hole 33. A bearing 36 is installed 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 the pivot point.

[0043] The support structure for the roller 19 is described as follows: The roller 19 is positioned between a pair of side frames 29 and 30, and with the roller shaft 28 inserted through the insertion hole 33, and is rotatably cantilevered to the first side frame 29 by the bearing 36 described above.

[0044] Furthermore, when the support unit 3 is switched to the deployed state described above, the roller 19 is switched to an overlapping state where it is located in a range that overlaps with the flange 8 when viewed from the front and rear directions. Conversely, when the support unit 3 is switched to the retracted state described above, the roller 19 is switched to a non-overlapping state where it is located in a range that does not overlap with the flange 8 when viewed from the front and rear directions. In other words, in this example, the deployed state is synonymous with the overlapping state, and the retracted state is synonymous with the non-overlapping state.

[0045] The motor 22 is a geared motor mounted and supported on the side frame 30 that does not cantilever the roller 19, and has a drive shaft 42 that is identical or substantially coaxial with the roller shaft 28. The motor 22 is located on the side of the side frame 30 opposite to the side 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] Furthermore, the motor 22 is attached and supported to the side frame 30 using one of the connecting rods 32.

[0047] The side roller 23 is supported on the support frame 21 so as to be rotatable around its axis as a pivot point. The axis of the side roller 23 is set to face in a direction along the circular radial direction of the end face (specifically, the end face of the flange portion 8 opposite to the winding drum portion 8) in the direction of the reel axis 6 of the reel 2, which is rotatably supported from below by rollers 19 provided on each of the multiple support units 3, when the side roller 23 is in contact with the end face of the flange portion 8. Specifically, with respect to a roller 19 and a side roller 23 supported on one support frame 21, the axis of the side roller 23 is oriented 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 multiple (specifically four) rollers 19, the side rollers 23 that are in contact with the end of the reel 2 also rotate around their axis as a pivot point. Incidentally, these side rollers 23 face 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 toward the unit base 18 so that it can swing up and down with the end of the support frame 21 closer to the reel axis 6 in the overall length direction (overall length direction of the side frames 29, 30) (specifically, the connecting rod 31) as a pivot point, and a hydraulic lifting actuator 39 interposed between the end of the support frame 21 further from the reel axis 6 in the overall length direction (specifically, the connecting rod 32) and the unit base 18, and which drives the support frame 21 to swing up and down with the connecting rod 31 as a pivot point by extending and retracting.

[0050] The support member 38 is integrally mounted and protrudes upward from the unit base 18. The lifting actuator 39 is composed of a retractable hydraulic cylinder or hydraulic jack, etc. One end of the lifting actuator 39 is connected to the connecting member 41 fixed to the upper surface of the unit base 18 so as to be rotatable around the axis of the shaft portion 41a of the connecting member 41, and the other end is connected to the connecting rod 32 so as to be rotatable around 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 pivot point, thereby displacing the positions of the roller 19 and side roller 23 upward. Conversely, by retracting the lifting cylinder 39, the support frame 21 swings downward around the connecting rod 32 as a pivot point, thereby displacing the positions of the roller 19 and side roller 23 downward.

[0052] Therefore, by displacing the roller 19 upward using the lifting mechanism 24, the reel 2 is lifted while being supported from below by the roller 19, and is switched to an ungrounded state where it is floating above the upper surface of the base 1. On the other hand, by displacing the roller 19 downward using the lifting mechanism 24, the reel 2 is displaced downward together with the roller 19 and is switched to a grounded state where it is in contact with the upper surface of the base 1.

[0053] To describe the support structure for a single reel 2 using multiple (specifically four) support units 3,3,3,3, the support unit 3, when switched to the deployed state, is slid in the front-rear direction toward the reel axis 6, thereby bringing the outer surface of the roller 19 into contact with the lower side of the outer surface of the flange 8, and switching to a state in which the reel 2 can be supported from below (supportable state). 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 where their circular outer surfaces are in contact with each other when viewed in the axial direction of the reel 2 or the roller 19.

[0054] Then, when the front and rear pairs of support units 3,3,3,3, each of the support unit sets individually provided for each corresponding flange portion 8,8 on the left and right are switched to a supportable state, each of the left and right flange portions 8,8 is switched to a state where it is clamped from below by the front and rear pairs of rollers 19,19,19,19 on both sides in the intersecting direction. Incidentally, in order to prevent the reel 2 from shifting as much as possible, it is desirable that the four rollers 19,19,19,19 contact the flange portions 8,8 at the same or approximately the same timing, and that each support unit 3,3,3,3 slides so 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 support units 3,3,3,3 are raised by their respective lifting mechanisms 24,24,24,24, thereby lifting the reel 2 and switching it from a grounded state to an ungrounded state. In this process, it is desirable that the rollers 19,19,19,19 are driven upward in sync with each other.

[0056] When the reel 2 is switched to the ungrounded state, it becomes possible to rotate it using the rollers 19, 19, 19, 19. In other words, the ungrounded state is a state in which the reel 2 is rotatably supported on the upper surface of the base 1.

[0057] On the other hand, in the non-grounded state, the reel 2 can be returned from the non-grounded state to the grounded state by lowering all the support units 3,3,3,3 in synchronization with each other. Furthermore, from this state, by sliding all the support units 3,3,3,3 in synchronization with each other in a direction away from the reel axis 6, the contact between the outer surfaces of the rollers 19,19,19,19 and the corresponding outer surfaces of the flanges 8,8 is released, and the reel 2 is switched to a state where it is not supported by the four rollers 19,19,19,19 (unsupported state).

[0058] Next, the configuration of the means for restricting the sliding of the slide mechanism 4 will be described based on Figures 1 and 5.

[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 consists 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. In the illustrated example, the plurality of pin receivers 48 and the plurality of positioning holes 47 are omitted except for some.

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

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

[0062] On the other hand, the pin receivers 48 are provided at multiple locations on the mounting plate 11 where positioning holes 47 can be formed. The pin receivers 48 are metal locking members that are elliptical in plan view and convex in side cross-section view. The pin receivers 48 are embedded in the mounting plate 11 and fixed by fasteners such as bolts so that their upper and lower surfaces are flush with the upper and lower surfaces of the mounting plate 11 in side cross-section view.

[0063] The pin receiver 48 has a pin receiver hole 49 into which the tip of the positioning pin 46 is screw-engaged. In a plan view, this pin receiver hole 49 is circular in shape and drilled towards its center, and when the above-mentioned plurality of positioning holes 47 are in positions that overlap with each other, it is positioned in a position that overlaps with these positioning holes 47 in a plan view.

[0064] By sliding the switching direction side table 16 and the crossing direction side table 17 to their respective predetermined positions, the positions of the three holes 47a, 47b, and 47c in a plan view coincide, forming a 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 the positioning pin 46 through the multiple positioning holes 47 and the pin receiving hole 49, and tightening the tip of the pin by screwing it into the pin receiving hole 49, the slide mechanism 4 (specifically, the switching direction side table 16 and the crossing direction side table 17) is switched to a locked state in which its sliding operation is restricted (prohibited). On the other hand, by releasing the screw engagement of the positioning pin 46 and pulling the positioning pin 46 out of the positioning hole 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 support 51 will be explained based on Figures 1 and 5.

[0067] In addition to the above-described 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 support 51 has a mounting seat 53 that is detachably fixed to the upper surface of the unit base 18 by fasteners such as bolts, and a cylindrical insertion portion 54 that extends above it in the left-right direction. The joint pipe 52 is a tubular member whose total length (length in the left-right direction) is set to the length from the pipe support 51 of one support unit 3 to the pipe support 51 of another support unit 3 that is positioned in the left-right direction relative to the said support unit 3.

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

[0070] With the reel device configured as described above, a cross-directional table 17 is provided on the upper surface of the base 1 to support the support unit 3 so that it can reciprocate and slide in the front-rear direction. Therefore, even if the support unit 3, including the rollers 19, is heavy, it becomes easy to move the support unit 3 as intended and position it in the appropriate location.

Claims

1. Bass and, A reel comprising: a winding drum portion that is rotatably supported and has a circular outer surface in a cross-sectional view centered on the reel axis which is the axis of rotation; and a contact portion that has a circular outer surface in a cross-sectional view centered on the reel axis and rotates integrally with the winding drum portion, wherein the winding drum portion rotates to wind a string-like body, such as a cable or hose, onto the outer surface side of the winding drum portion, or to unwind the string-like body wound onto the outer surface side, Multiple support units that support the reel from below and allow it to rotate while floating above the upper surface of the base, The support unit is supported on the upper surface of the base so as to be able to reciprocate and slide in an intersecting direction that intersects the axis of the reel, The support unit has a roller that is rotatably supported with respect to a roller axis which is parallel to the reel axis, Furthermore, the support unit is configured to be switched to a supportable state in which the outer surface of the roller can be brought into contact with the outer surface of the contact portion by sliding it to one side in the intersecting direction, thereby supporting the reel from below, and to be switched to a non-supportable state in which the roller is separated from the reel and cannot support it from below by sliding it to the other side in the intersecting direction. The support units are provided in pairs in the direction of the intersection or the axis of the reel, and each is configured to be reciprocally slidable in directions toward or toward each other. A reel device characterized by the following features.

2. Each of the multiple support units has an actuator that rotates the roller, The support unit is configured to transmit the rotational power of the roller to the reel when switching to a supportable state and when the roller is supporting the reel from below. The reel device according to claim 1.

3. The sliding mechanism includes a rail on the intersecting direction side formed in the intersecting direction, and a slider on the intersecting direction side that slides back and forth along the rail. The reel device according to claim 1.

4. The aforementioned contact portion is a flange portion integrally formed on the end side of the winding drum portion, Viewed from the direction of the reel axis, a pair of support units, each positioned on one side and the other side of the contact portion, are provided as a set of support units. When switching to the supportable state, the contact portion is held between the rollers of the pair of support units of the support unit set. The reel device according to claim 1.

5. The support unit has side rollers that contact the end face of the reel in the direction of the reel axis, thereby restricting the reel from moving in the direction of the reel axis. The reel device according to claim 1.

6. A pair of flanges are integrally formed on both ends of the winding drum portion, The support unit set is provided for each of the pair of flange portions. The reel is supported from below by the four rollers when the support unit is switched to the supportable state. The reel device according to claim 4.

7. Each of the multiple support units includes a lifting mechanism for raising and lowering the roller, When switching to the supportable state, the structure is such that the reel is switched between a grounded state in which it is in contact with the upper surface of the base and an ungrounded state in which it is supported from below by the roller and floats above the upper surface of the base by the lifting mechanism. The reel device according to claim 6.

8. The slide mechanism is configured to support the support unit on the upper surface of the base so that it can reciprocate and slide in the switching direction, which is along the axis of the reel. The roller is configured such that the support unit is slid by the sliding mechanism to one side in the switching direction, thereby switching it to an overlapping state where it is located in a range that overlaps with the contact portion when viewed from the intersecting direction, and is slid to the other side in the switching direction, thereby switching it to a non-overlapping state where it is located in a range that does not overlap with the contact portion when viewed from the intersecting direction. The support unit is configured to be able to switch between the supportable state and the non-supported state while in the overlapping state. The reel device according to claim 1.

9. The support unit is configured such that, upon switching to the non-overlapping state, it switches to a stored state where the entire unit is positioned on the base in a plan view, and upon switching to the overlapping state, it switches to an unfolded state where at least a part of it protrudes outward from the base in a plan view. The reel device according to claim 8.

10. The sliding mechanism includes a switching direction rail formed in the switching direction and a switching direction slider that slides back and forth on the switching direction rail. The reel device according to claim 8.

11. The system includes a locking means that switches between a locked state in which the sliding of the roller by the sliding mechanism is restricted and the roller is locked in place, and a movable state in which the locked state is released and the sliding of the roller by the sliding mechanism is permitted. The reel device according to claim 1.
