  According to the drum winding material drawing machine according to the first aspect of the present invention, the undulation arm arranged at the end of the machine base with the winding material, for example, the drum wound with electric wires, is opened outward. Then, the drums are placed on the pair of placement rollers in the direction of the same axis, and then the hoisting arms are returned to the upper side of the machine base, and the drums are placed on the upper holding rollers disposed on the undulation arms. Can be used by fixing the state of the undulating arm by the arm state holding means.

  When pulling out the strip wound around the drum, for example, electric wires, the lifting and lowering operation means of the rotation center means is operated to project the rotation center axis downward, and the wheels on both sides adjacent to the rotation center axis When the wires are pulled out, the machine base rotates around the rotation center axis in accordance with the drawing direction of the wires and corresponds to the drawing direction of the wires. It is possible to secure a smooth drawer. Accordingly, the wires can be smoothly drawn out from the drum, and the user can perform the work very stably and efficiently. Further, since the position of the machine base is fixed by the rotation center axis, even if the electric wires are pulled, it does not move in that direction.

  In the above, when the wheels are arranged in the vicinity of both sides of the front and rear ends of the machine base, the wheels on both sides of the end part where the rotation center axis of the machine base is arranged are floated. The machine base is in a three-point support state by the rotation center shaft and two wheels arranged at the other end, and is supported in a very stable state, and the wheel is, as described above, Since it is arranged so as to be movable and rotatable in any direction, as described above, the machine base rotates in accordance with the drawing direction of the strip material such as electric wires, and the drum drum Is in a direction perpendicular to the direction in which the strip is pulled out, and an extremely smooth pull-out can be ensured.

  In addition, in the above, when pulling out the strip material such as electric wires, if the strip material is pulled out from the upper side of the drum, when the strip material is pulled out obliquely with respect to the drum body of the drum, There may be a case where the rotating operation of the machine base by the wheels does not function well and falls. Therefore, it is appropriate in many cases that the strips such as electric wires are drawn from the lower side of the drum.

  In addition, according to the drum winding material drawing machine of the present invention, when work at another place on the site becomes necessary, it can be easily moved to that place. In this case, the lifting / lowering operation means of the rotation center means is operated to raise the rotation center shaft, and the machine base is returned to the state of being supported by all the wheels arranged thereon, and pulled or moved using the movement operation means. By performing the pushing operation, the machine base can be moved freely and smoothly on a plane such as a floor surface to a required place without requiring a great effort. As described above, the wheel can be moved in any direction while being placed on a plane, and the above movement can be freely performed. Needless to say, when it is necessary to go over a step or protrusion during movement, it is possible to lift a drawer by grabbing a part of the hoisting arm or other appropriate part and then go over it.

  Further, when all the drum strips have been pulled out, it is naturally necessary to remove the drum and replace another drum on which strips of necessary wires and the like are wound. In the drum winding material drawing machine according to the first aspect of the present invention, the drum placed on the pair of placement rollers is held from above by the upper holding roller of the hoisting arm and held on the machine base. However, such a state of the undulating arm is held by the arm state holding means. Therefore, in this case, it is only necessary to release the holding of the above-described undulating arm state by the arm state holding means. Then, it becomes possible to raise the undulating arm and tilt it outward, take out the drum placed on the pair of placement rollers, and wind up other necessary wires and other strips. The drum can be replaced. Thereafter, as described above, the undulation arm may be moved to suppress the upper side of the drum that has been replaced by the upper suppression roller, and the state of the undulation arm may be held by the arm state holding means.

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

  Furthermore, as described above, since the drum can be replaced very easily, for example, even when multiple types of electric wires are used in electrical work, etc. It is sufficient to prepare a drawer with a sufficient number of drums around which wires of a certain unit length are wound to satisfy the expected length for each type. Therefore, the transport amount is reduced, the drums can be stacked side by side, and the drawer can be used, so that there is an advantage that transport can be performed in a smaller space.

  According to the drum winding material drawing machine according to the second aspect of the present invention, the undulation arm in which the drum placed on the mounting roller of the machine base is held by the upper holding roller is connected to the mounting end of the undulation arm of the machine base. It is possible to fix and hold the pair of holding arms of the arm state holding means disposed at the end portion on the opposite side to the lower side from the upper side of the opposite side by simply rotating the pair of holding arms downward. More specifically, the fixed holding is performed by simply rotating the pair of holding arms downward from the upper side of the opposite side as described above, so that the undulations are formed in the locking groove formed at the tip side of the holding arm. This can be performed by entering and locking the locking protrusions that protrude from the outer surfaces of the vertical bar portions on both sides of the arm, and the holding state can be reliably fixed by a simple operation.

  As the arm state holding means, the above configuration is preferable to ensure a simple and reliable operation, but various other configurations can be adopted. For example, a pair of elastic cords each having a base end fixed to a side portion of the machine base, and engaged with locking protrusions fixed to the outer surfaces of both vertical bars of the hoisting arm on the distal end side. An elastic string provided with a stop hook can be employed. In this case, simply by locking the hooks of the elastic strings on both sides to the locking projections of the vertical bars on both sides of the hoisting arm, the upper arm of the hoisting arm can be easily mounted on the mounting roller. It is possible to keep the drum held down.

  According to the drum winding material drawing machine 3 of the present invention, as described above, when the material wound on the drum is pulled out from the drum placed on the machine base, first, as described above, the rotation center means is moved up and down. It is only necessary to operate the operating means to lower the rotation center axis and to lift some of the wheels adjacent to the rotation center so that the machine base can be rotated around the rotation center axis but cannot be moved. Thereafter, the strip wound around the drum can be pulled out freely. If the strip material is drawn out in a direction that is not perpendicular to the direction of the drum drum, the machine base will naturally be placed on the machine base around the rotation center axis if the strip material is pulled. The drum drum is rotated so as to be perpendicular to the direction in which the strip is pulled, and the strip can be pulled out from the drum stably. On the other hand, since the lower end of the rotation center shaft is in a pressure contact state on a plane such as a floor surface on which the machine base is arranged as described above, the machine base is pulled when the strip is pulled. There is no such thing as moving in the direction.

  According to the drum winding material drawing machine of the third aspect of the present invention, the lowering operation of the rotation center shaft as described above is performed by lowering the operation rod of the elevating operation means, and this is further performed in front of the case member. It can be performed by a simple operation only by engaging with an engaging groove formed on the side of the opening. Moreover, since the said rotation center axis | shaft is comprised with the vertical axis | shaft which coat | covered the lower end with the shock absorbing material, there is also no possibility of causing damage to the floor surface etc. which have arrange | positioned the said machine stand.

  According to the drum winding material drawer 4 of the present invention, since the moving operation means is configured, when the drawer on which the drum is placed is to be moved to another work place or the like at the work site. Is a state in which a pulling operation rod having a base rotatably coupled to an upper end horizontal bar portion of the hoisting arm is rotated outward to extend from the hoisting arm, and then the outer end of the pulling operation rod ( You just need to grab the grip at the tip and pull it in the direction you want to move. In this way, the drawer can be easily moved to the target location without requiring a special strong force to lift and carry the drawer. Needless to say, as described above, when there is a step or the like in the middle of movement, the drawer can be lifted up by grabbing a part of the hoisting arm and the like.

  In the above, since the wheels arranged on the machine base are arranged so as to be movable in any direction as described above, the pulling operation rod of the moving operation means as described above is gripped and pulled. In this case, the machine base can be freely moved in the target direction.

  In the drum winding material drawing machine according to the fourth aspect of the present invention, since the moving operation means is configured as described above, the pulling operation rod is rotated inward (upper side of the hoisting arm) at the base. If it is moved, there is no risk of getting in the way when the strip is pulled out of the drum, and it becomes compact. In particular, when the drum is lowered from the loading roller and the drawer is carried or stored, it is turned upside down on the hoisting arm and folded as described above. If the arm is turned down and is parallel to the frame on the machine base, the overall structure becomes extremely compact and does not require a large storage space.

  The above-described configuration is appropriate as the moving operation means, but any means can be used as long as it can be used to move the machine base by pulling or pushing on the plane on which it is placed. It is not limited to. Various means can be employed.

But there is.

  Therefore, according to the drum winding material drawing machine of this embodiment, drums d wound with various strip materials, for example, electric wires w, cables, cords, hoses, etc. are shown in FIGS. As such, it can be set and used for the withdrawal of those strips.

Here, a case where the drum winding material drawing machine of this embodiment is used for electrical work will be described as an example.
Therefore, here, the wires are w or various cables as the strip material.
First, when using this drawer, a drum d around which necessary types of electric wires w are wound is prepared. Usually about six types of electric wires are used, but several drums d, d. One drawer is enough. When there are a plurality of types having different diameters of the drum d, a drawer corresponding to them is prepared. Specifically, as described above, a drawer having a plurality of locking grooves 8b corresponding to the holding arms 8 and 8 is prepared.

  A drum d around which wires w are wound is set in the drawer. That is, as shown in FIGS. 6 and 7, the drum d is placed on the pair of mounting rollers 3 and 3 in the direction of the same axis and opened outward from the rear end of the machine base 2. As shown in FIG. 7, the hoisting arm 4 in a raised state is raised and brought into a state in which the drum d is held from the upper front by an upper holding roller 5 disposed on the hoisting arm 4. The holding arms 8, 8 of the arm state holding means which are open outwardly are raised, in particular as shown in FIGS. 7 and 8, so that in particular as shown in FIGS. After the tip side is opened to the outside slightly beyond the thickness of the vertical plate portions 4a, 4a of the hoisting arm 4, as shown in FIGS. 7 and 8, the holding arms 8, 8 are formed. Certain locking grooves 8b, 8b are formed in the locking projections 9, 9 projecting from the vertical plate portions 4a, 4a. Sealed cell. Thus, the drum d can be set in the drawer very easily.

  As shown in FIGS. 6 and 7, the drawer set in this way has the pull operation rod 7 c of the moving operation means 7 extended in the outward extension direction of the hoisting arm 4, and then the pull operation is performed. By grasping and pulling the grip portion 7d at the tip of the flange 7c, the machine base 2 can be easily moved to a desired location. As described above, the machine base 2 is provided with the four free wheels 1, 1,..., Thereby enabling movement on the floor surface f in a free direction. Since there is no need to lift and carry the drawer base 2, it does not require much labor. If there is a step or the like on the way and exceeds this, it is necessary to lift this drawer by grabbing a part of the hoisting arm 4, for example, the upper end horizontal bar portion 4b or the upper holding roller 5 etc. It is usually a short distance or time and does not require a great deal of effort as a whole. The operation of moving the drawer does not require much labor and can be easily performed.

  Note that the above pulling operation rod 7c can move the drawer even when the grip portion 7d is gripped and pushed. In addition, the pulling operation rod 7c is folded back to the base side of the hoisting arm 4 as will be understood from the above description when it becomes a hindrance except when the drawer is moved. be able to.

  After the drawer is moved to a place where it is used on the site, the operation bar 6c of the rotation center means 6 is pushed down. This push-down operation is performed after the free wheel 1 and 1 attached to the rear end piece 2c are slightly lifted by grasping the rear end piece 2c which is the rear end side of the machine base 2. The operation rod 6c is pushed down against the compression spring member 6j until the lower end of the rotation center shaft 6 protrudes slightly below the lower end of the free wheel 1 and 1 attached to the rear end piece 2c. The operating rod 6c is rotated to the right at that time, and this is moved to the side of the front opening 6g of the case member 6i as shown in FIGS. 4 (b), 4 (e), 8 and 9. The engagement groove 10 is configured to be slid into the engagement groove 10. Thus, the rotation center shaft 6b is maintained in a state of protruding downward. As shown in FIGS. 8 and 9, the rear end side of the machine base 2 is the rotation center shaft 6a, and the front end side is the front end. The two free wheels 1 and 1 attached to the piece 2b are respectively supported, and the stable support by the three-point support is ensured as a whole.

  Thereafter, the electric wires w wound around the drum d mounted on the machine base 2 of the drawer can be pulled out as necessary. The electric wires w are pulled out from the lower side of the drum d for the reasons described above.

  In the above state, the drum d is slidably mounted on the placement rollers 3 and 3 on the lower side, and the upper side is similarly slidably held by the upper holding roller 5 on the upper side. Therefore, when the wires w are pulled out, smooth rolling is performed while being held in that position.

  For example, when the electric wires w are drawn from 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 2 is moved to the central axis of rotation. Rotating about 6a, the axial direction of the winding drum of the drum d is changed to a direction orthogonal to the drawing direction. As described above, the machine base 2 is a three-point support by the rotation center shaft 6a of the rotation center means 6 disposed in the center of the rear end piece 2c and the free wheels 1 and 1 attached to the front end piece 2b. When the electric wires w are pulled out, the free wheels 1 and 1 are turned in necessary directions and rotated around the rotation center shaft 6a.

  At this time, as described above, since the lateral displacement prevention rods 3a and 3a are arranged in the vicinity of both sides of the placement rollers 3 and 3 as described above, the wires w are as described above. When the drum d is pulled from an oblique direction with respect to the axial direction of the winding drum of the drum d, the drum d may move slightly laterally on the placement rollers 3 and 3, but the drum d Since the portion comes into contact with the lateral displacement prevention rods 3a, 3a on the laterally displaced side and cannot move any further, there is no possibility of falling off the roller portion of the mounting rollers 3, 3.

  Further, since the movement of the machine base 2 is sealed by the rotation center shaft 6a, as described above, when the electric wires w are pulled out, the machine base 2 itself moves in the drawing direction. Not that. Further, since the rotation center shaft 6a is covered with a synthetic rubber cushioning material 6a2 on the lower diameter portion 6a1 at the lower portion thereof, even if the rotation center shaft 6a is pressed against the floor surface f or the like, the floor surface There is no problem that hurts f and the like.

  Thus, the drawer machine base 2 is naturally oriented in a stable direction with respect to the wires w being pulled out. Therefore, when the wires w are pulled out, the drawer machine base 2 itself is There is no possibility of problems such as falling and making it impossible to withdraw. Further, there is no fear that the machine base 2 itself moves in the pulling direction during the pulling. Therefore, the drawer can be performed stably at any time without any delay, and the electrical work using the drawer can be smoothly performed.

  When all the wires w of the drum d have been pulled out, it is necessary to replace them with another drum d wound with the same size wires w. In this drawer, the holding arms 8, 8 are If the locking projections 9 and 9 are removed from the locking grooves 8b and 8b and tilted to the outer side of the front end of the machine base 2, the hoisting arm 4 becomes free to move, The rear end of the machine base 2 can be knocked outward. Then, after doing in this way, the drum d from which the electric wires w have been pulled out is removed from the placement rollers 3 and 3 on the machine base 2 and another drum d around which the corresponding electric wires w are wound. Can be replaced. Thereafter, as described above, the raising and lowering arm 4 and the holding arms 8 and 8 may be operated to hold the mounting state of the drum d.

  If the drawer is to be moved to another location, as shown in FIGS. 4 (a), 4 (d), 6 and 7, the operating rod 6c of the rotation center means 6 is rotated to the left. Then, it is removed from the engagement groove 10 and is raised by the action of the compression spring member 6j, and at the same time, the rotation center shaft 6b is raised. Thus, as shown in FIG. 6 and FIG. 7, the machine base 2 of the drawer is supported by the front and rear four free wheels 1, 1,. When the pulling operation rod 7c is folded back to the base side of the hoisting arm 4, as described above, the pulling operation rod 7c is extended in the extending outward direction of the hoisting arm 4 and then the pulling operation rod 7c. The grip portion 7d at the tip of 7c may be grasped and pulled. The machine base 2 can be easily moved to a desired place. As described above, when there is a step or the like in the middle of movement, it goes without saying that a part of the hoisting arm 4 or the like can be grasped to pull up the puller and to go over it.

When the drawer is not used, the drum d can be removed and the drawer itself can be folded compactly. Therefore, the space for storage and transportation can be very small.
That is, if the drum d is removed, the holding arms 8 and 8 are tilted down from the front end side of the machine base 2 as shown in FIGS. The side plates 2a and 2a can be placed (folded) in a mutually parallel state with almost no gap. At this time, the holding arms 8 and 8 are held and held by the holding and holding portions 8d and 8d disposed on the rear side portions of the side plates 2a and 2a of the machine base 2, respectively. Retained.

  Then, as shown in FIGS. 3 (a) and 3 (b), the hoisting arm 4 is tilted from the rear end side of the machine base 2 into a prone state and is placed on the side plates 2a and 2a. 8 and 8 can be mounted (folded) in a mutually parallel state with almost no gap. Further, the pulling operation rod 7c coupled to the upper end horizontal bar portion 4b of the hoisting arm 4 via the mounting pipe 7a and the like is moved upward from the extended state of the hoisting arm 4 shown in FIG. Can be rotated 180 degrees to the folded state toward the base of the hoisting arm 4 shown in FIG. Thus, particularly as shown in FIG. 3B, this drawer can be made compact to a state close to a single plate.

  In this embodiment, there is no holding means such as the holding and holding portions 8d and 8d for the undulating arm 4 described above, but the above folded state collapses due to normal storage or transportation operation. Almost never occurs. In order to hold the compact state more surely, as described above, the two metal plates constituting the holding and holding portions 8d and 8d can be folded over the width of the holding arms 8 and 8 when folded. It is sufficient to adopt a size that allows the vertical plate portions 4a and 4a of the hoisting arm 4 to be placed thereon to be sandwiched and to hold the vertical plate portions 4a and 4a. In this case, it is appropriate to move the arrangement of the holding and holding portions 8d and 8d slightly forward.

  Therefore, the storage or loading space can be made extremely small during storage or transportation. Specifically, as described above, when the drawer is folded, it becomes almost plate-like, so that a plurality of drawers can be stacked on each other when stored or transported.

  The drawer | drawing-out machine of this invention drum winding material can be utilized in field | areas, such as an industrial field which manufactures this, and electric construction using this.
