SUMMARY OF THE INVENTION The present invention, however, has a machine base on which wheels are arranged so as to be freely rotatable in a state of being placed on a plane, and on the machine base in parallel with front and rear ends thereof. A pair of mounting rollers rotatably arranged in the circumferential direction of the shaft, the mounting rollers arranged so that a drum oriented in the same axial direction as those can be mounted, and the pair of mounting rollers. A pair of side part regulation rollers sandwiching the drum mounted on the roller on the mounting roller at the positions of the collar parts on both sides thereof, with the longitudinal axis being centered on each side part of the machine base. A side regulating roller rotatably arranged and an inverted U-shaped undulating arm rotatably and rotatably arranged at the front and rear ends of the machine base, respectively. The upper restraining rollers for restraining are installed in parallel with the upper and lower horizontal bars, respectively, and the above-mentioned undulating arms. The elastic coupling means are arranged in the middle of both sides of the drum, and when the drum is held by the upper restraining roller while standing upright, the both sides of the undulating arms are elastically moved to each other so as to maintain the state. The drum winding material drawer is composed of elastic coupling means for coupling.

Therefore, according to the drum winding material drawer of the present invention, a material, for example, a drum around which electric wires are wound is placed on the pair of mounting rollers in the direction coaxial with them, and Both undulating arms that were open to the outside of the end are raised, and the upper holding rollers arranged on the arms raise and lower the drum from the front and rear sides. Both sides of the undulating arm are elastically connected for use.

[0006] In this state, if necessary, the strip material wound around the drum, in this case, the electric wires can be pulled out. The wires will be pulled out from the lower side of the drum. For example, when the electric wires are pulled out obliquely with respect to the winding drum of the drum, the machine base is rotated by the action of the wheels as the electric wires are pulled out to wind the drum. Change the axial direction of the body to the direction orthogonal to the drawing direction. In this way, the drawer will naturally turn freely in a stable direction relative to the withdrawal of the wire material such as electric wires, so that there is no problem that the drawer itself falls and the drawer cannot be pulled out. The withdrawal can be done at any time without delay, and the work using the withdrawal can be performed smoothly.

When the strips such as electric wires are pulled out from the upper side of the drum, when the strips are pulled out obliquely with respect to the drum winding cylinder as described above, the wheel The rotation of the machine base due to a class may not function well and may cause the machine to fall. Therefore, as described above, the strip material such as the electric wires should be pulled out from the lower side of the drum.

Further, when pulling out such a strip, both the undulating arms are pulled inward by the elastic coupling means, and the drum mounted on the pair of mounting rollers is elastically acted by the pair of upper restraining rollers. Since the material is suppressed, only the necessary amount of the strip material is drawn out according to the drawing operation, and there is no problem that a long strip material is drawn out unnecessarily due to the rotation due to the inertia of the drum. Therefore, of course,
There is almost no need to rewind the overdrawn strip after it is pulled out.

Further, as described above, even when the strip material such as the electric wires is pulled out obliquely with respect to the drum winding drum, the two flange portions of the drum are respectively placed as a pair for mounting. Since the roller is in contact with the roller at two locations and the pair of upper restraining rollers at two locations, a troublesome situation may occur in which the strip material to be pulled out comes off the drum and goes out to the outside of the collar portion. That's not it. Therefore, naturally, the troublesome work of returning the strip that has come off the drum to the original state does not occur.

When all the strips of the drum have been pulled out, it is necessary to remove the drum and replace another drum around which the strips of necessary electric wires are wound.
In this drawer, both elastic arms can be pulled outward from the front and rear ends by releasing the elastic connection at both sides of the elastic arms, so after doing so, it is easy You can remove the drum from which the strip has been pulled out and replace it with another drum on which the strip is wound. After that, as described above, both the undulating arms may be raised and the elastic connecting means may be connected to each other so as to maintain the state.

When the drawer is moved a little while the drum is mounted, the upper lateral rod portions of both upstanding arms can be grasped with one hand at the same time and easily carried.

When the drawer is not used, the drum can be removed and the drawer itself can be folded compactly. Therefore, the storage space is small and it is convenient for transportation.

Further, as described above, since the drum can be remounted easily, even if a plurality of types of electric wires are used for electrical work, the drum must have the same shape and dimensions. For example, it is sufficient to prepare one drawer, and it is sufficient to prepare the number of drums wound with electric wires of a certain unit length for each type so as to satisfy the intended use length. Therefore, the amount of transportation is small, the drums can be laid down side by side, and the drawer can be used. Therefore, there is an advantage that transportation can be performed in a smaller space.

In the above-described drum winding material drawing machine of the present invention, four wheels are used as the wheels, and four of them are used.
It is possible to adopt a configuration in which the individual wheels are positioned on the machine base on a virtual arc centered at the center thereof and the rolling movement direction of the wheels is attached to the tangential direction of the virtual arc. In the case of such a construction, even though the strip is drawn out from an oblique direction with respect to the axial direction of the drum, the four machine bases are provided with the drawing even though the strip is drawn out in an oblique direction. Because the wheels rotate to rotate the axial direction of the winding drum of the drum in a direction orthogonal to the drawing direction, the drawer naturally stabilizes against the drawing of the strip material. You will be able to move in any direction you like. Therefore, even when the strip is pulled out obliquely to the axial direction of the drum,
There is no problem such as the drawer falling over and disabling the drawer. Further, at this time, since the machine base only rotates and does not move in the pull-out direction, there is no problem such as collision with surrounding articles.

As the wheels, it is possible to use an appropriate means other than the above, for example, a floating roller or the like. It is also possible to position these wheels or rollers on a virtual arc centered around the center of the machine base, and attach them with their rolling movement direction oriented in the tangential direction. The number of wheels or rollers is 3 or more, but it is preferably 4 or more in order to maintain a stable state. Further, the center of the virtual arc is appropriately aligned with the center of the machine base as described above, but more preferably is aligned with the center of the drum mounted on the machine base.

According to this structure, even when the withdrawing direction of the strip is not necessarily orthogonal to the axial direction of the drum winding drum, the machine base is rotated by the action of the wheels in accordance with the withdrawal. Since the direction of movement is changed and the direction of withdrawal is set to the direction orthogonal to the axial direction of the drum winding drum, the machine base maintains a stable posture, and there is no problem such as falling down and being unable to withdraw. Further, as described above, at this time, the machine base only rotates and does not move in the pull-out direction, so there is no possibility of colliding with surrounding articles or wall surfaces and damaging them.

If wheels having a large diameter are adopted as the wheels, even if the place where the drawer is placed is not flat but has a slightly large unevenness, the wheels roll over the wheels. It is possible to prevent the rotation of the machine base from being hindered. Therefore,
Even when the drawer is placed in such an uneven place, when the strip is pulled from an oblique direction as described above, the drawer does not fall down and the strip is pulled out. Can be done smoothly.

Since the mounting roller described above mounts the drum rotatably in the circumferential direction of the shaft thereof, at least the flange portions on both sides of the drum are mounted securely in a rollable state. Anything can be done. Further, the interval is an appropriate width so that the mounted drum can be stabilized. This mounting roller is arranged on the machine base in parallel with its front and rear ends. The side of the machine base parallel to the mounting roller is named front and rear end, and is orthogonal to the mounting roller. The sides of the machine base facing each other are named side parts, and the names of the front and rear ends and the side parts are for convenience.

It is appropriate that the side regulating rollers are arranged so as to contact the outer edges of the collar portions on both sides of the drum. Each side regulating roller rolls in a tangential direction of a virtual arc (arc centering on the axis of the drum) passing through a position where it touches, so as not to impair the smooth rolling of the drum. Orient it and attach it to the machine base.
Usually, a pair of the side regulating rollers is sufficient, and each side regulating roller is placed in the intermediate portion of the pair of mounting rollers at a position corresponding to both ends thereof in a direction in which the side regulating rollers are raised with respect to the machine base. It may be arranged so as to be rotatable around the vertical axis facing. The distance between the pair of side regulating rollers may be slightly larger than the width of the drum.

When the side regulating roller is constructed as described above, the drum mounted on the placing roller is unnecessarily moved to the left and right even when the strip is pulled out, or the side portion of the machine base or the undulating arm. There is no problem such as contact with the vertical part of the side portion of the sheet and impairing its smooth rolling.

Further, in the drum winding material drawing machine of the present invention, one of the two undulating arms is hoisted and swung to a position higher than the mounting roller at one end of the machine base. It is freely attached, and when one drum is not placed on the placing roller, the one undulating arm is configured to be foldable from above to a state parallel to the upper surface of the machine base. The other undulating arm of the machine base is attached to the other end of the machine base at a position lower than the placement roller so that the undulation can freely rotate, and the other undulation arm is folded from below to a state parallel to the upper surface of the machine base. When the drawer is not used, the drum is removed and one of the undulating arms is attached to the upper surface side of the machine base as described above. And the other undulating arm is on the bottom side of the machine base. Folding is rotated, it can be made compact state until the one plate-like. Therefore, when storing or transporting, the storage or loading space can be made extremely small, and when storing or transporting multiple items, these can be stacked on top of each other, so that existing stacking is not possible. It is more space-saving than. It is more convenient because the removed drums can be stacked and carried while being transported.

The upper restraining rollers are each arranged between the vertical strips on both sides of the undulating arm, and, as described above, the drums placed parallel to the upper end horizontal rod portion and placed on the placing rollers are placed on the upper holding rollers. It is held from above so that it does not fall off. The structure may be the same as that of the mounting roller. Then, as described above, it suffices to be able to hold the drum securely on the mounting roller without impairing the smooth rolling motion associated with the drawing of the strip material of the drum.

In the elastic coupling means, when the drum is placed on the placing roller and the two undulating arms are erected toward the upper center of the machine base, the undulating arms are directed to both outward sides. It is not limited to a specific configuration as long as they can be elastically coupled to each other so as to hold them in that state so that they do not fall over.

Therefore, for example, the elastic coupling means may be composed of coupling projections projecting from the upper portions on the outer surface side of the vertical strips on both sides of each undulating arm, and a ring-shaped elastic member extending between them. With this configuration, as described above, when both undulating arms are raised, as described above, on both sides of the undulating arms, between the connecting protrusions protruding from the upper portions of the side vertical pieces of the undulating arms, respectively. By straddling the ring-shaped elastic member, both undulating arms can be easily elastically coupled.

The ring-shaped elastic member 7b is provided between the coupling projections 7a,
The front undulating arm 5a and the rear undulating arm 5b can be easily elastically coupled by straddling the 7b.
The bridging is performed by locking a small ring on one coupling projection 7a and a large ring on the other.

Therefore, according to the drawing machine for the drum winding material of this embodiment, the drum d around which various materials such as electric wires, cables, cords or hoses are wound is
As shown in FIG. 1, it can be set and used for drawing out those strips.

Here, a case where the drum winding material drawer of this embodiment is used for electrical work will be described as an example. However, here, the electric wires w or various cables are used as the strip material. First of all, when using this drawer,
A drum d around which the required types of electric wires w are wound is prepared. Usually, about 6 types of electric wires are used, and several drums d are prepared for each kind of electric wire, each of which has a length corresponding to the planned length of use. Only one drawer is required. When there are plural types of drums having different diameters, a drawer corresponding to them is prepared.

A drum d wound with electric wires w is set in the drawer. That is, as shown in FIGS. 1 to 3, the drum d is replaced by the roller portions 3b, 3 of the pair of mounting rollers 3, 3.
In particular, the front undulating arm 5a and the rear undulating arm 5b, which are placed on b in the direction coaxial with them and are opened outward at the front and rear ends of the machine base 1, as shown in FIG. 1
As shown in FIG. 2, the drum portions d are raised, and the roller portions 6b, 6b of the upper restraining rollers 6, 6 arranged on the upper restraining rollers 6, 6 hold the drum d from the front and rear upper portions, particularly as shown in FIGS. In addition, both side portions of the front undulating arm 5a and the rear undulating arm 5b can be elastically coupled and used by the elastic coupling means 7, 7.

More specifically, the coupling by the elastic coupling means 7 and 7 is performed by the front undulating arm 5a and the rear undulating arm 5b.
Each side vertical piece of 5at, 5at and 5bt, 5b
coupling protrusions 7a, 7a respectively arranged on the upper part of the outer surface of t
And 7a, 7a, in particular as shown in FIGS.
This is performed by bridging the ring-shaped elastic members 7b and 7b. Thus, the drum d can be set in the drawer very easily. As described above, the ring-shaped elastic members 7b and 7b are bridged with each other by locking a small ring on one coupling projection 7a and a large ring on the other.

After being set in this way, the electric wires w of a desired size wound around the drum d can be drawn out if necessary. For the electric wires, for the reasons described above,
It will be pulled out from the lower side of the drum d. Drum d
In the above state, the roller portion 3 of the mounting rollers 3, 3
b and 3b are rotatably mounted, and the upper portions are also rotatably restrained by the roller portions 6b and 6b of the upper restraining rollers 6 and 6, so that the wires w can be pulled out. While being held in that position, smooth rolling is performed.

When the electric wires w are drawn out, for example, in an oblique direction with respect to the axial direction of the winding drum of the drum d, as the electric wires w are drawn, the machine base 1 moves to the wheel. Due to the action of 2, 2, ..., It rotates about its center, and the axial direction of the winding drum of the drum d is changed to the direction orthogonal to the drawing direction.

In this way, as the wire w is pulled out, the drawer naturally faces in a stable direction with respect to it. Therefore, when the wire w is pulled out, the drawer 1 itself falls and is pulled out. There is no possibility that problems such as being disabled will occur, so that you can withdraw it at any time without delay,
The work of electrical work using the drawer can be done smoothly.

Although the drum d may move toward the left and right side portions of the machine base 1 especially when the drawer is pulled out as described above,
In the drum d placed on the roller portions 3b and 3b of the placement rollers 3 and 3, the wires w are pulled obliquely with respect to the axial direction of the winding drum by the action of the side regulating rollers 4 and 4. Also, in the case of the spillage, the lateral movement on the pull-out direction side is hindered, and the side plate 1b of the machine base 1 or the side vertical piece 5at of the front undulating arm 5a.
This eliminates the risk of contact with the like and ensures smooth rolling.

Further, as described above, the wires w are connected to the drum d.
Even when the drum d is pulled out obliquely with respect to the winding drum, the two flange portions of the drum d are located at two locations with respect to the roller portions 3b and 3b of the pair of mounting rollers 3 and 3, respectively. ,
The pair of upper restraining rollers 6, 6 are in contact with the roller portions 6b, 6b of the upper portion at two places, and there is a troublesome situation in which the drawn electric wires w come off the drum d and come out of the flange portion. There is no danger of it occurring.

Further, when pulling out the electric wires w as described above, both the undulating arms 5 are moved by the elastic coupling means 7, 7.
a and 5b are pulled inward with respect to each other, and the drum d mounted on the roller portions 3b and 3b of the pair of mounting rollers 3 and 3 is paired with the roller portions 6b and 6b of the upper restraining rollers 6 and 6, respectively.
Since it is elastically suppressed by, the electric wire w is drawn out only by a necessary amount according to the drawing operation, and there is a problem that the electric wire w is unnecessarily drawn out due to the rotation due to the inertia of the drum d. Absent.

When all the electric wires w of the drum d have been pulled out, it is necessary to replace them on another drum d on which the electric wires of the same size are wound. In this drawer, the elastic coupling means 7, When the ring-shaped elastic members 7b, 7b of 7 are removed from between the coupling protrusions 7a, 7a and 7a, 7a, the front undulating arms 5a and the rear undulating arms 5b are respectively moved from the front and rear ends to the outside as shown in FIG. Therefore, the drum d from which the electric wires w have been pulled out can be easily removed and replaced with another drum d around which the electric wires w are wound. After that, as described above, the front undulating arm 5a and the rear undulating arm 5b are raised, and the elastic coupling means 7 and 7 are connected to each other so as to maintain the state.

When the drawer is slightly moved while the drum d is placed, the upper and lower horizontal bars 5ay and 5by of the raised front and rear undulating arms 5a and 5b are simultaneously grasped and lifted by one hand. Can be carried to.

When the drawer is not used, the drum d can be removed and the drawer itself can be folded compactly. Therefore, the space for storing and transporting the same can be small. That is, as shown by the alternate long and short dash line in FIG. 1, if the drum d is removed, the front undulating arm 5a is tilted to the upper surface side of the machine base 1, and the rear undulating arm 5b is rotated to the bottom side of the machine base 1. Folding, in particular, as shown in FIG. 5, can be made into a compact state up to a state close to a single plate.

Therefore, the storage or loading space can be made extremely small during storage or transportation. Specifically, as described above, the drawer becomes a plate when folded, so that a plurality of it can be stacked on top of each other when storing or transporting, so existing stacking is not possible. It is far more space-saving than anything. It is more convenient because the removed drums d can be stacked and carried while being transported.

Further, as described above, since the drum d can be replaced very easily, even if a plurality of types of electric wires are used in the electrical work described as an example of use here, a single unit is required. Prepare a drawer, and use a sufficient number of drums d for each electric wire w.
Please prepare and replace if necessary. As a result, the amount of transportation is reduced, the drums d can be laid down side by side, and the drawer can be operated as described above. Therefore, there is an advantage that transportation can be performed in a small space.

After the work, the drum d is removed,
As described above, the folded drawer is configured such that, as shown in FIG. 5, it is provided between one coupling protrusion 7a of the rear undulating arm 5b and the inner portion of the pin 5ap for rotation on the corresponding side of the front undulating arm 5a. The ring-shaped elastic member 7b is hung over the ring-shaped elastic member 7b, and the ring-shaped elastic member 7b is hooked between the coupling protrusion 7a on the opposite side of the front undulating arm 5a and the turning pin 5bp on the opposite side of the rear undulating arm 5b. It can be passed and hold its folded state.

FIG. 6 shows a machine base 11 of another embodiment. As shown in FIG. 6, a side plate 11 of the machine base 11 is shown.
One row of coupling holes h1, h1 ..., H2, h2 ..., H3, h3 ... Are continuously formed at the upper, middle and lower stages of b, 11b, respectively. Therefore, this machine base 11 is replaced with the machine base 1
If it is used instead of, the mounting positions of the front undulating arm 5a, the rear undulating arm 5b, and the mounting rollers 3 and 3 can be easily changed according to the size of the drum d to be mounted thereon. This is convenient because it can be done.

That is, if the size of the drum d is small, in order to reduce the interval between the mounting rollers 3 and 3, the intermediate coupling holes h2, h2, ... The upper and lower undulating arms 5a are attached to the upper connecting holes h1, h1 ... As much as necessary from the center, and the rear undulating arms 5b are attached to the lower connecting holes h3, h3. At this time, coupling holes are continuously formed along the lengthwise direction on the side vertical pieces 5at, 5at, 5bt, and 5bt of the front undulating arm 5a and the rear undulating arm 5b, respectively, and the upper portions It is more preferable if the mounting positions of the pressing rollers 6 can be changed up and down.

Therefore, according to the drum winding material drawer of the present invention, the winding material, for example, the drum around which the electric wires are wound is placed on the pair of mounting rollers in the coaxial direction. , Raising both undulating arms that have been opened to the outside of the front and rear ends, and holding the drum from the front and rear side upper parts by means of the respective upper pressing rollers arranged on it, and by the elastic coupling means. , Both sides of the undulating arms can be elastically coupled and easily used.

In this state, the strip material wound on the drum can be pulled out if necessary. The strip will be pulled out from the bottom of the drum. For example, when the strip material is to be pulled out obliquely with respect to the drum winding cylinder, the machine base is rotated by the action of the wheels as the strip material is pulled out, and the drum is wound. Change the axial direction of the body to the direction orthogonal to the drawing direction. In this way, the drawer will naturally move freely in a stable direction relative to the withdrawal of the strip material, so there is no problem that the drawer itself falls and the drawer cannot be disabled. However, it can be done smoothly and the work using the drawer can be done smoothly.

When the strip material is pulled out from the upper side of the drum, when the strip material is to be pulled out in an oblique direction with respect to the winding drum of the drum, as described above, The rotation of the robot does not work well and there is a risk of falling. Therefore, as mentioned above, the strip is
It should be pulled out from the underside of the drum.

Further, when pulling out such a strip, both the undulating arms are pulled inward by the elastic coupling means, and the drum mounted on the pair of mounting rollers is elastically moved by the pair of upper restraining rollers. Since the material is suppressed, only the necessary amount of the strip material is drawn out according to the drawing operation, and there is no problem that a long strip material is drawn out unnecessarily due to the rotation due to the inertia of the drum. Therefore, of course,
There is almost no need to rewind the overdrawn strip after it is pulled out.

Further, as described above, even when the strip material is to be pulled out obliquely with respect to the winding drum of the drum, both flange portions of the drum are respectively attached to the pair of mounting rollers. Since it is in contact with the pair of upper restraining rollers at two places at two places, there is no possibility that a troublesome situation such that the drawn-out strip comes off the drum and goes out to the outside of the collar portion. Therefore, naturally, the troublesome work of returning the strip that has come off the drum to the original state does not occur.

When all the strips of the drum have been pulled out, it is necessary to remove the drum and replace the other drum around which the required strip is wound. In this drawer, the elastic coupling means is used. By releasing the elastic connection at both sides of both undulating arms, you can pull both undulating arms outward from the front and rear ends, and after doing so, the strips can be easily pulled out. The drum can be removed and replaced with another drum that has a strip of material. After that, as described above, both the undulating arms may be raised and the elastic connecting means may be connected to each other so as to maintain the state.

When the drawer is moved a little while the drum is placed, it is possible to easily carry the upper and lower horizontal bars of both upstanding arms with one hand at the same time.

When the drawer is not used, the drum can be removed and the drawer itself can be folded compactly. Therefore, the storage space is small and it is convenient for transportation.

Further, as described above, since the drum can be remounted easily, even if a plurality of types of electric wires are used for electrical work, the shape of the drum should be the same. For example, it is sufficient to prepare one drawer, and it is sufficient to prepare the number of drums wound with electric wires of a certain unit length for each type so as to satisfy the intended use length. Therefore, the amount of transportation is small, the drums can be laid down side by side, and the drawer can be used. Therefore, there is an advantage that transportation can be performed in a smaller space.

In the above-described drum winding material drawing machine of the present invention, four wheels are used as the wheels, and four of them are used.
In the case of adopting a configuration in which the individual wheels are positioned on the machine base on a virtual arc centered on the center thereof and the rolling movement direction of the wheels is oriented in the tangential direction of the virtual arc, Even with a very simple structure, even when the strip is pulled out obliquely with respect to the axial direction of the drum, the machine base is rotated by the action of the four wheels together with the pulling out, Since the axial direction of the drum winding cylinder is changed to the direction orthogonal to the drawing direction, the drawing machine naturally moves freely in a stable direction with respect to the drawing of the strip material. It is a thing. Therefore, even when the strip is pulled out in an oblique direction with respect to the axial direction of the drum, there is no problem that the drawer falls and the drawer cannot be pulled out. Further, at this time, since the machine base only rotates and does not move in the pull-out direction, there is no problem such as collision with surrounding articles.

Further, in the drum winding material drawing machine of the present invention, one of the two undulating arms is raised and lowered to a position higher than the mounting roller at one end of the machine base. It is freely attached, and when one drum is not placed on the placing roller, the one undulating arm is configured to be foldable from above to a state parallel to the upper surface of the machine base. The other undulating arm of the machine base is attached to the other end of the machine base at a position lower than the placement roller so that the undulation can freely rotate, and the other undulation arm is folded from below to a state parallel to the upper surface of the machine base. When the drawer is not used, the drum is removed, one undulating arm is tilted to the top side of the machine base, and the other undulating arm is rotated to the bottom side of the machine base as described above. Move it and fold it to create a single plate It can be in door state. Therefore, when storing or transporting, the storage or loading space can be made extremely small, and when storing or transporting multiple items, these can be stacked on top of each other, so that existing stacking is not possible. It is more space-saving than. It is more convenient because the removed drums can be stacked and carried while being transported.
