DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a front view of this embodiment,
FIG. 2 shows a side view thereof. The columns 12 are provided at four corners of the drum housing device 10. The distance between the columns 12 in the longitudinal direction may be determined depending on the width and the number of the drums 14 to be housed. On the other hand, the distance between the columns 12 in the width direction may be determined by the diameter of the flange 18 of the flanged drum 14 around which the wire and the cable 20 are wound around the outer circumference. The height of the column 12 is the number of storage stages and the flange 1
It may be determined by the diameter of 8. 16 is a connecting portion,
The columns 12 are connected to each other in the width direction. In the present embodiment, since the number of storage stages of the drum 14 is two, the connecting portion 16
Also, two stages are provided for four (only two are shown in the drawing). As will be described later in detail, a concavo-convex portion 22 is formed on the upper surface of the connecting portion 16. The uneven portion 22 houses the drum 1
It is formed for adjustment when the diameter of the flange 18 of No. 4 is changed. The uneven portion 22 may not be formed integrally with the connecting portion 16, but may be formed as a separate member and fixed to the connecting portion 16.

Reference numeral 24 denotes a support bar, which is arranged in parallel in two rows in the upper and lower stages at a distance equal to or smaller than the diameter of the flange 18 of the drum 14 to be supported. Both ends of the support bar are hooked by the recessed portions of the uneven portion 22 formed in the connecting portion 16 to be supported and the displacement of the drum housing device 10 in the width direction is prevented. Since each support bar 24 is hooked on the recessed portion of the uneven portion 22, the diameter of each support bar 24 is set to be less than the pitch of the uneven portion 22. The distance between the support bars 24 at each stage is such that the flange 18 of the drum 14 is
A support roller, which will be described later, is fitted on the support bar 24 so that the drum 14 is set to have a diameter smaller than the diameter of the drum 14.
In order to support the flange 18 of the drum 14, it is necessary that the distance be equal to or smaller than the diameter of the flange 18 of the drum 14. When the diameter of the supporting drum 14 or the diameter of the flange 18 changes, the position of the support bar 24 with respect to the connecting portion 16 needs to be changed. In that case, the interval between the support bars 24 can be set to be equal to or smaller than the diameter of the flange 18 of the drum 14 by changing the hooking portion of the uneven portion 22. Although not shown in FIGS. 1 and 2, a means for preventing the support bar 24 from moving in the length direction with respect to the connecting portion 16 is provided.

Reference numeral 26 denotes a support roller, which is rotatable in the same number as the number of flanges 18 corresponding to at least the number of drums 14 to be supported per support bar 24, and is movable in the length direction of the support bar 24. It is possible to be fitted. A ball bearing is disposed inside the support roller 26 to reduce frictional resistance between the support roller 26 and the outer peripheral surface of the support bar 24. Further, in the case of the present embodiment, since three drums 14 are supported in each stage, six support rollers 26 are provided for each support bar 24. The width of the support roller 26 may be determined according to the width of the flange 18 to be supported. The outer peripheral surface of the support roller 26 is formed into an arc surface so that the center has the smallest diameter. By forming this arcuate surface, the flange 18 can be supported at two points for each support roller 26, and the deviation of the flange 18 on the support roller 26 can be prevented. In this embodiment, a plurality of drums 14 are accommodated in each stage, and a support roller 26 is provided to rotate each drum 14 independently of the support bar 24.
When only one drum 14 is arranged on the upper side, or when a plurality of arranged drums 14 all rotate in the same direction at the same time, it is not necessary to provide the support roller 26, and if the support bar 24 can rotate. Good. At this time, the distance between the support bars 24 must be smaller than the diameter of the flange 18 of the drum 14.

Reference numeral 28 denotes a pop-out preventing portion, which connects the columns 12 to each other in the lengthwise direction. In this embodiment, the drum 14
Since the number of accommodating steps is two, the pop-out prevention portion 28
Also, four for two stages are provided. The pop-out prevention portion 28 prevents the drum 14 that has become lighter by pulling out the wire and cable 20 from popping out of the drum housing device 10 by the force of pulling out the wire and cable 20.
The mounting position of the pop-out prevention portion 28 may be determined in consideration of the diameter of the flange 18 and the like. The pop-out prevention portion 28 is removable from the column 12, and the drum 1
When mounting or lowering 4, the pop-out prevention portion 28 is removed from the column 12 to perform the work. In the above-described embodiment, the number of storage stages of the drum 14 is two, but it may be one or three or more. When the wire and cable 20 wound around the drum 14 accommodated (supported) in the drum accommodating device 10 is pulled out, the drum 14 rotates and the support roller 26 also rotates, so that there is almost no resistance, and the wire and cable 20 Can be pulled out. Next, a mechanism for adjusting the distance between the support bars 24 will be described with reference to FIG. In the above embodiment, in order to adjust the distance between the support bars 24, the uneven portion 22 of the support bars 24 is used.
However, the minimum adjustment amount is limited to the pitch of the uneven portions 22. Further, since the positions of the support roller 26 and the flange 18 must be accurately matched in advance, it may be difficult to mount the drum 14. In order to solve this, the present inventor has devised a mechanism for adjusting the distance between the support bars 24.

Of the pair of support bars 24, the support bar 24 on the left side in the drawing has a fixed position with respect to the connecting portion 16. On the other hand, of the support bars 24, the support bar 2 on the right side in the drawing
Reference numeral 4 is movable in the left-right direction along a guide portion 30 provided on the connecting portion 16. The guide portion 30 also prevents the right side support bar 24 from rising. If the weight of the drum 14 does not cause the support bar 24 to lift, the guide portion 30 may be omitted. 32 is a chain, one end of which is fixed to a protruding portion 34 protruding from the connecting portion 16. Reference numeral 36 denotes a lever, which is rotatable on the connecting portion 16 about a shaft 38 in the direction of arrow A.
The middle portion of the chain 32 is fixed to the portion 40 of the lever 24. However, the chain 32 fixed to the portion 40
The part of can be changed. The chain 32 is wound around the outer circumference of the support bar 24 on the right side by a half turn and extends toward the lever 24. With this configuration, when the lever 24 rotates in the direction of arrow A, the chain 32 is pulled leftward, so that the right support bar 24 also moves leftward together with the support roller 26. The other end of the chain 32 is free.
Reference numeral 42 is a hooking portion, which is formed in a hook shape and which has a connecting portion 16
It is fixed on. An arbitrary chain ring on the other end of the chain 32 can be hooked on the hooking portion 42.
When it is desired to maintain the state in which the lever 24 is pulled in the direction of arrow A, the state can be maintained by hooking the chain ring of the chain 32 corresponding to the hook portion 42. In addition,
If the lever 24 itself is provided with a lock mechanism that maintains the state of being pulled in the direction of arrow A, the hooking portion 42 may be omitted.

The state shown in FIG. 3 is before the lever 24 is pulled. When the drum 14 is mounted in this state, the drum 14
The lower end of the flange 18 is grounded (position indicated by 18a). At this time, when the right support bar 24 is moved to the rightmost position, the support rollers 26 can move on both support bars 24 without interfering with the flanges 18. Therefore, the position of the support rollers 26 should correspond to the flange 18. You can
When the support roller 26 is made to correspond to the flange 18, the lever 2
When 4 is pulled so as to rotate in the direction of arrow A, the support bar 24 on the right side moves to the left to lift and support the drum 14 (position shown by 18b). At that time, the chain ring of the chain 32 corresponding to the hook portion 42 is attached to the hook portion 4
When it is hooked at 2, the supporting state of the drum 14 can be maintained. As a mechanism for adjusting the distance between the support bars 24, in addition to the above-described configuration, for example, as a means for moving the movable support bar 24, a screw rod screwed into a fixed nut is rotated by a handle, and the rotation thereof is performed. The support bar 24 may be configured to relatively move toward and away with the above. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention.

[0012]

When the drum accommodating device according to the present invention is used, each flange of the flanged drum has at least the same number of support rollers as the support rollers on each of the support bars arranged in parallel with each other at a distance equal to or smaller than the diameter of the flange. Since the drum is rotatably fitted, the drum is rotatably supported by the support roller. Therefore, when the wire or cable wound around the drum is pulled out, the drum can rotate together with the support roller. As a result, once the drum is housed,
Not only for storage but also for pulling wires and cables from the drum, there is no need for a drum jack or a special mechanical device for setting the drum on the drum jack, and the wires and cables can be easily pulled out from the drum.
