Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long material feeding device for feeding a long material such as a wire material such as an electric wire, a branch line, a cable such as an optical fiber or a string, or a hose, and particularly to a long material wound in an annular shape. The present invention relates to a long object feeding device that can smoothly feed an object.

In many cases, filament materials such as electric wires, branch lines, optical fibers, and long objects such as hoses are provided in a state of being wound in an annular shape on a rotating body such as a drum or a reel. Then, when pulling out the long object such as the linear material wound in the annular shape, the feeding device which rotatably supports the long object wound in the annular shape and makes it possible to pull out the long object. Is used.

Several prior arts have also been proposed for such pay-out devices. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2003-235122), the rotation of the rotating body is allowed when the filament wound around the rotating body is drawn out, and the rotation of the rotating body is promptly rotated when the drawing out of the filament is stopped. We have proposed a brake system for a wire transfer system that can be stopped. The brake device proposed in this document is provided with a base body 5 having a clamp that can be removably fixed to a wire carrier, a first brake member supported by the base body, and a first brake member opposed to the first brake member. A second brake member, a guide rod that supports the second brake member, and a guide rod that is slidably supported by the base body in a direction in which the first brake member and the second brake member come into contact with and separate from each other. A feed mechanism that slides the guide rod to adjust the distance between the first brake member and the second brake member, and the first brake member is a coil that biases the first brake member toward the second brake member. It is slidably supported by the guide rod via a spring.

Further, in Patent Document 2 (JP 2006-160465A), even if the cable pulling operation is stopped, the cable drum is quickly stopped without inertial rotation due to the inertia caused by the pulling force of the cable. As a cable drawer that can be prevented, a base, a vertical frame raised from the base, and a substantially parallel horizontal axis protruding horizontally from an upper portion of the vertical frame and an intermediate portion in the height direction. And an oscillating frame oscillatingly hung on the upper horizontal axis, and the intermediate horizontal axis is set at a height position capable of rotatably supporting the cable winding drum. A horizontal rod having a braking portion that contacts the outer peripheral surface of the side plate of the cable winding drum; and a cable contact portion that contacts the cable pulled out during the cable pulling operation to separate the braking portion from the outer peripheral surface of the drum side plate. We propose a cable drawer that has and.

As mentioned above, it is an instrument that has been used to pull out filaments such as cables even before, and some technologies to stop the rotation of the rotating body or drum when the drawers of filaments such as cables are stopped are proposed. Has been done. However, the brake device according to the patent document 1 "adjusts the feed amount of sliding the guide rod 10 by the feed mechanism 11 to control the elastic force that presses the inner surface pad 35 and the outer surface pad 47 against the flange 305. This allows the rotation of the drum 301 when the electric wire 311 wound around the drum 301 is pulled out, and promptly stops the rotation of the drum 301 when the pulling out of the electric wire 311 is stopped. The frictional force between the pad 35 for the outer surface and the pad 47 for the outer surface and the flange 305 of the drum 301 is adjusted." Therefore, the drum cannot be immediately stopped depending on the torque during the inertial rotation. Was there.

In addition, the cable pull-out base proposed in the above cited document 2 also states, "When the pulling-out of the cable is stopped, the swing frame automatically descends and leans due to the decrease in the pulling-out tension of the cable, and the braking portion has the drum side plate. When the gravity of the rocking frame is concentrated on the braking part, the descending inclination is stopped further while the gravity of the rocking frame is concentrated on the braking part. By contacting, the cable winding drum can be stopped with almost no inertial rotation, and even if it occurs, it can be stopped with extremely few conditions, so regardless of the frequency of use of the cable drawer, the reverse winding phenomenon of the cable is always prevented. It allowed the inertial rotation of the drum after the cable was pulled out. Therefore, in the past, there was still room for improvement in accuracy when stopping the rotation of the rotating body and the drum.

Further, as a result of prioritizing the stopping of the rotating body and the drum when the drawing of the wire is stopped, there is still room for improvement in smoothly drawing the wire.

FIG. 1 is a side view showing the operation of the long-object feeding device 11 according to the first embodiment, and shows (A) the rotating state of the rotating body 20 and (B) the rotating state of the rotating body 20, respectively. 2A and 2B are an exploded front view and a partial cross-sectional view, respectively, of a long object feeding device 11 according to the first embodiment.

The long object feeding device 11 according to the first embodiment shown in FIGS. 1 and 2 is particularly used as a long object feeding device 11 for feeding a wire S member such as an electric wire, an optical fiber or a cord. Although it is embodied, it can also be used for feeding other long objects such as hoses.

The long object feeding device 11 according to the first embodiment includes a rotating body 20 that holds the long object wound in an annular shape, and a base 30 that rotatably holds the rotating body 20. A braking device 40 for stopping the rotation of the rotating body 20, an operation member 50 for actuating or stopping the braking device 40 with the pulling out and/or the stopping of the withdrawal of the long object, and the linear strip S. The guide member 60 prevents the protrusion.

The rotating body 20 has a holding portion 21 that holds the inner peripheral surface of the filament S provided in a wound state, a radial frame 22 that fixes the holding portion 21, and a contour on the tip side of the radial frame 22. It is formed by a ring-shaped frame 23 provided so as to be configured, and its central portion is fixed to a shaft member 24 which is rotatable around an axis. Therefore, the rotating body 20 is rotatable around the shaft of the shaft member 24. The shaft member 24 is fixed to a base 30 which will be described later, and preferably includes a rotation smoothing member such as a bearing in order to smoothly rotate around the axis. As a result, the rotating body 20 can smoothly rotate without receiving frictional resistance, and the filament S supported by the rotating body 20 can be pulled out smoothly.

It is also preferable that the holding portion 21 constituting the rotating body 20 is provided so as to be movable in the length direction of the radial frame 22. Since the distance between the holding portions 21 arranged to face each other corresponds to the inner diameter of the wire rod S in the held and held state, it is possible to move the holding portions 21 in accordance with the winding diameter of the wire rod to be fed out. This is because Thereby, the wire rods having various winding diameters can be held.

In the present embodiment, the radial frame 22 is formed of two rod-shaped members that intersect at the center of rotation, and a ring-shaped ring-shaped frame 23 is provided so as to connect the tip ends thereof. However, the rotating body 20 does not necessarily have to be configured by the radial direction frame 22 and the ring-shaped frame 23, and for example, a side surface member formed in a disk shape and a holding surface of the filament S in the disk side surface member. It can also be formed with the holding portion 21 provided on the side.

The holding portion 21 is composed of a rectangular small piece portion 21a fixed to the radial frame 22 and a strip portion 21b fixed to the small portion portion 21a, and the strip portion 21b is wound. It is formed in a curved shape along the inner peripheral surface of the filament S in the state. The holding portions 21 are arranged so as to face each of the radial frames 22, and a total of four sets of two sets of the facing portions that are arranged so as to face each other are provided. It is also possible to arrange three or five or more at regular intervals, or to form the holding portion 21 in an annular shape or a column shape. The holding portion 21 can be formed in any shape and structure as long as it can hold the inner peripheral surface of the wire member S provided in a wound state, and preferably, the held wire S (in a wound state). The filament S is formed so as to securely fix the filament S so as to prevent relative rotation between the filament S) and the holding portion 21. This is to prevent relative rotation of only the filament S in the wound state after the rotating body 20 is stopped by the braking device 40 described later.

The base 30 functions to hold each component in the present embodiment, for example, the rotating body 20, the braking device 40 and the operation member 50 described later, and in the present embodiment, a frame (a pipe and a pipe). (Including a rod member). However, as long as the function can be ensured, it may be formed by a plate-shaped or box-shaped member.

The base 30 according to the present embodiment is provided with two leg members 30a and 30b, a stand-up frame 30c that stands up in the vertical direction from the intersection of the leg members, and an upper end portion of the stand-up frame 30c. It is composed of a hand-held part 30d, and each of them is formed by using a pipe or a rod member. The rising frame 30c is provided with a bearing 31 for fixing the shaft member 24 that rotatably mounts the rotating body 20. In the present embodiment, the bearing 31 is formed of an L-shaped angle member extending to the front side of the rising frame 30c, but any shape and structure can be used as long as the shaft member 24 can be held. Can be formed.

Further, a bearing 32 of the operating member 50 is provided in a rising shape on the leg portion 31a on the rear side (the rear side opposite to the pulling-out direction) of the base 30. The bearing 32 need only be capable of swingably holding the operation portion described below at a predetermined position, and thus the bearing 32 is not limited to the leg portion and may be provided at any position. Further, the rear leg portion 30a is provided with a wire 52 receiving frame 33 for holding a wire 52 of the operation member 50 described later. In the present embodiment, the wire 52 receiving frame 33 is formed by bending a rod-shaped member into an L shape, but may be formed in any shape as long as the end portion of the wire 52 can be held at a predetermined position. You can

The braking device 40 functions as a so-called brake and limits the rotation of the rotating body 20 or stops the rotating rotating body 20. In particular, in the present embodiment, the braking mechanism used as the bicycle braking device 40 can be used. In the long object feeding device 11 according to the first embodiment, the rotation of the rotating body 20 is prevented. Hub brakes such as band brakes, roller brakes, and servo brakes that stop the shaft are used. The braking device 40 needs to operate so as to stop the rotating body 20 that is rotating by drawing out the filament S when the drawing out of the filament S is stopped, and is preferably 80 N or more, more preferably 80 N or more. Particularly preferably, a brake (braking device 40) having a braking force of 150 N or more can be used. That is, the rotating body 20 rotating by pulling out the filament S may have a large rotational torque due to the combined mass of the filament S rotating together with the rotor 20. On the other hand, if the rotating body 20 inertially rotates at the stage where the drawing-out of the filament S is stopped, the wound filament S is forcibly fed out, which may cause entanglement. Therefore, in the braking device 40 according to the present embodiment, a rotating device having a sufficient braking force, especially the rotation angle of the rotating body 20 after the pulling out of the long object is 180° or less (that is, half the circumference or less), preferably 90. A linear member based on the inertial rotation is used, which has a braking force that stops the rotating body 20 at a rotation angle of less than or equal to 1° (that is, 1/4 rotation or less), and particularly preferably at 45° or less (that is, 1/8 rotation or less). This is to suppress the delivery of S.

The braking device 40 according to the present embodiment includes an operating member 50 that operates when the linear member S is pulled out and stopped, and the braking device 40 advances and retreats following the operation of the operating member 50. It is configured to be operated by the wire 52 that operates. That is, the mass of the braking device 40 does not directly act on the rotating body 20, but the wire 52 is moved forward and backward, and the braking means is operated thereby, so that the rotating body 20 is braked. There is.

In the present embodiment, the operating member 50 is provided with a standing bearing 32 on the leg portion 30a on the rear side of the base 30 (on the rear side opposite to the pull-out direction). And a wire 52 that is connected to the operating rod 51 and that operates and/or stops the braking device 40. In this embodiment, the operating rod 51 extends forward from the bearing 32 and is bent in an L-shape toward the front of the wound wire S held by the rotating body 20. A ring-shaped guide portion 53 that guides a long object pulled out from the rotary body 20 is provided on the front portion of the filament S (wound filament S) held by the 20.

The base end side of the wire 52 is connected to the operating rod 51, and the tip end side of the wire 52 is connected to the braking device 40. In the present embodiment, such a braking device 40 is used that stops the rotation of the rotating body 20 or allows the rotating body 20 to freely rotate by the forward/backward movement of the wire 52.

Then, as shown in FIG. 1(A), the tip end side of the operating rod 51, that is, the portion existing on the front side of the wound wire S held by the rotating body 20, is always the operating rod 51. It is being cheated downward due to its weight. As a result, the wire 52 is pulled, whereby the braking device 40 acts and the rotation of the rotating body 20 is blocked. On the other hand, when the filament S held by the rotating body 20 is pulled out, the distal end side of the operating rod 51 is lifted by the filament S passing through the guide portion 53, as shown in FIG. As a result, the tension on the wire 52 is released, and the braking state of the braking device 40 is released.

Therefore, by pulling out the filament S held by the rotating body 20, the operating rod 51 is lifted as shown in FIG. 1(B), thereby freeing the braking device 40 and allowing the rotating body 20 to freely rotate. To do. On the other hand, when pulling out the wire is stopped, the tension of the wire S disappears, so that the operating rod 51 rotates downward by its own weight, thereby pulling the wire 52 and pulling the braking device 40. The inertial rotation of the rotating body 20 can be quickly stopped by operating the rotating body 20. In particular, in the long-object feeding device 11 according to the first embodiment, the operating member 50 is formed by using the operating rod 51 that vertically swings when the filament S material is pulled out or stopped.

2A and 2B are an exploded front view and a partial cross-sectional view, respectively, of a long object feeding device 11 according to the first embodiment. As shown in this figure, when the filament S provided in a wound state is installed in the long object feeding device 11, the holding portion 21 of the rotary body 20 is wound in the wound state. A restraining member 25 is provided in order to prevent the installed filament S from falling off, and is fixed to the shaft. In the present embodiment, the restraining member 25 is formed by the radial frame 22 and the ring-shaped frame 23, and the ring-shaped frame 23 is further provided with a handle 26. When the operating rod 51 is lifted to bring the braking device 40 into a free state, it is possible to wind the filament S by rotating the rotating body 20 with the handle 26 in the direction opposite to the feeding direction. Become. The restraining member 25 only needs to prevent the filament S (the filament in the wound state) set in the holding portion 21 from falling off, and thus can be formed using a disc or the like.

Further, in the long-object feeding device 11 according to the present embodiment, the filament S does not extend to the outside of the rotary body 20 below the rotary body 20 at the time of paying and winding. Further, a guide member 60 is provided. In this embodiment, the guide member 60 includes a curved portion 61 that extends along the lower side of the ring-shaped frame 23 of the rotating body 20, and a retaining portion 62 that extends from the curved portion to the vicinity of the ring-shaped frame 23. It is formed by. By providing the guide member 60, even when the tension with respect to the filament S is loosened in the feeding and winding operations, it can be present in the rotating body 20 and the filament S is entangled (for example, (Entanglement with the shaft) can be prevented.

Next, with reference to FIGS. 3 and 4, a long object feeding device according to another embodiment will be specifically described. In particular, FIG. 3 shows the long object feeding device 12 in which the operating member 50 for operating the braking device 40 is different, and FIG. 4 shows the braking device 40 for suppressing the free rotation of the rotating body 20. It shows the extended device 13 for feeding out the elongated object. As shown in the following embodiments, the operation member 50 and the braking device 40 can be arbitrarily changed as long as their respective functions are ensured.

FIG. 3 is a side view showing the operation of the long-object feeding device 12 according to the second embodiment, showing (A) the stopped state of the rotating body 20 and (B) the rotating state of the rotating body 20, respectively. ing. An operation member 50 of the long object feeding device 12 according to the second embodiment is different from that of the long object feeding device 11 according to the first embodiment. That is, the long object feeding device 12 according to the present embodiment includes the operating rod 51 that swings in the front-rear direction when the wire rod is pulled out or stopped, and the lower end side of the operating rod 51, that is, the linear strip. The wire 52 is connected to the end portion on the side opposite to the guide portion 53, and the wire 52 is moved forward and backward by the forward and backward swinging of the operating rod 51. The braking device 40 permits braking and free rotation of the rotating body 20 by the advancing/retreating operation of the wire 52, similarly to the long-object feeding device 11 according to the first embodiment. ing.

In the long object feeding device 12 according to this embodiment, when the tension due to the pulling out of the filament S is not applied, as shown in FIG. 3(A), the operating rod 51 is the operating rod 51. And the rising frame 30c, the elastic member 60 such as a crane spring or a rubber provided between the rotating frame and the rising frame 30c stands upward from the center of rotation. At this time, the wire 52 is pulled, and the braking device 40 can brake the rotating body 20. On the other hand, when tension is applied to the wire S by pulling out the wire S, the operating rod 51 tilts forward as shown in FIG. Is released and the braking device 40 becomes free. As a result, the rotating body 20 can freely rotate, and the filament S can be pulled out smoothly. At this time, the operating rod 51 tilts the operating rod 51 forward against the restoring force of the elastic member 60. When the drawing of the wire S is stopped, the tension on the wire S disappears. Therefore, the operating rod 51 is restored by the restoring force of the elastic member 60 in the direction opposite to the drawing direction of the wire, and the braking is performed again. The device 40 can be operated. According to the long object feeding device 11 according to this embodiment, the strength of the force pulling the wire 52 can be adjusted according to the restoring force of the elastic member 60.

FIG. 4 is a partial cross-sectional front view showing the operation of the long-object feeding device 13 according to the third embodiment, where (A) the rotating state of the rotating body 20 and (B) the stopped state of the rotating body 20. Are shown respectively. The long object feeding device 13 according to the third embodiment has a braking device different from that of the long object feeding device 11 according to the first embodiment. That is, in the long object feeding device 13 according to the present embodiment, the rotary body 20, the base 30, and the operating member 50 have the same configuration as the long object feeding device 11 according to the first embodiment. However, the braking device 70 has a length selected from a caliper brake, a cantilever brake, a V-brake or the like rim brake, and a disc brake that sandwiches a disc body that rotates with an arbitrary portion of the rotor 20 or the rotor 20. It shows the scale feeding device 13.

Particularly, in the embodiment shown in FIG. 4, a braking device 70 is provided so as to sandwich the ring-shaped frame 23 of the rotating body 20, and the braking device 70 is interlocked with the vertical swing of the operating rod 51. Is configured to work. That is, as shown in FIG. 4(A), when the operating rod 51 is lifted by pulling out the filament S, the braking device 70 does not clamp the ring-shaped frame 23 and allows its free rotation. ing. On the other hand, as shown in FIG. 4B, when the leading end of the operating rod 51 is moved downward by its own weight by stopping the withdrawal of the filament S, the wire 52 is pulled to move the braking device 70. The pad 71 of the braking device 70 is operated to sandwich the ring-shaped frame 23. As a result, the long object feeding device that allows the rotary body 20 to freely rotate when the filament S is pulled out and can quickly and surely stop the rotor 20 when the filament S is pulled out. 13 is realized.

The long object feeding device according to the present invention can smoothly feed long objects such as electric wires, ropes, hoses, or sheets, and when the feeding is stopped, inertial rotation can be quickly stopped. As a result, it can be used as a device for delivering a long product without the problem of entanglement associated with the delivery of a long product due to inertial rotation.

Such a long object feeding device can be used not only for feeding an electric wire or an optical cable, but also for pulling out or feeding a long object in an agricultural field, an industrial field or the like.
Further, the device for feeding out the long product can be used as a device for winding up the long product by providing a handle for winding.
