Abstract

PURPOSE:To always properly and accurately hold a bobbin by arranging a hook to be hooked on an end part flange of the bobbin in the other end part of a base frame whose one end is pivoted on a balancer arm, and arranging a pin insertable in a center hole of the bobbin in an intermediate part of the frame. CONSTITUTION:When a bobbin is handled, in a condition where a balancer arm 1 is lowered, handles 16 and 17 are operated, and a tip part of a pin 6 is partially inserted in a center hole of the bobbin. Next, a base frame 4 is horizontally relatively displaced to the bobbin in the direction for a hook 5 to separate from the pin 6 against a spring means 13. Therefore, the broken bent tip edge of the hook 5 is displaced to the outer peripheral side of a flange (f) of the bobbin. After the pin 6 is completely inserted in the center hole while maintaining a relative displacement condition where the hook 5 is separated from the pin 6, the base frame 4 is returned to an original position by force of the spring means 13, and the hook 5 is reliably hooked on the end part flange (f) of the bobbin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used when a bobbin with an end flange, which is vertically arranged on a support base, is mounted on a rack with a support rod in a horizontal position, and vice versa. The present invention relates to a bobbin handling device suitable for use in some cases.

[0002]

2. Description of the Related Art As a conventional handling device for a bobbin or other relatively light weight bobbin having a relatively large center hole diameter, a conventional bobbin is inserted into the center hole of the bobbin and expanded there. In some cases, a rubber hollow body that holds the inner peripheral surface of the center hole is provided, and the posture of the rubber hollow body, and by extension, the bobbin held thereby, is changed under the action of a link mechanism using a hydraulic cylinder.

[0003]

However, in such a conventional apparatus, since the bobbin is held by the frictional force between the expanded rubber hollow body and the inner peripheral surface of the bobbin center hole, the weight of the bobbin is reduced. If it is large, there is a disadvantage that the expanded rubber hollow body cannot hold it properly, and in addition, a hydraulic cylinder and a link mechanism for changing the posture of the bobbin are required. It is inevitable that the apparatus structure becomes complicated and the apparatus becomes large, and further, there is a problem that the hollow rubber body cannot be inserted into a bobbin center hole having a small diameter. The present invention has been made as a result of studying to solve all such problems of the prior art, and the object of the present invention is to
Regardless of the weight of the bobbin, it can always be held properly and without the need for a special actuation mechanism and drive means for changing the bobbin position,
Moreover, it is an object of the present invention to provide a bobbin handling device capable of reliably holding the bobbin even if the diameter of the bobbin center hole is small.

[0004]

A bobbin handling device of the present invention is provided with a base frame having one end pivotally supported by a balancer arm, and the other end of the base frame is provided with:
A hook that engages with the end flange of the bobbin, and a pin that is displaceable in a direction toward and away from the hook and that can be inserted into the center hole of the bobbin, is provided at the intermediate portion of the hook so as to project therefrom. Spring means for constantly urging the pin in the direction of the hook is provided, and preferably two handles are projectingly provided on the base frame.
Supporting means for supporting the base frame rotatably around an axis orthogonal to the pivot axis of the base frame are provided.
Here, preferably, in at least one of the handles,
A switch that controls the operation of the balancer arm is provided.

[0005]

By such a bobbin handling device,
When mounting a bobbin with end flanges in a vertical position on a rack with support rods in a horizontal position, for example, with the balancer arm fully lowered, grasp the two handles and Insert the tip of the pin into the center hole to some extent, and then while displacing the pin in the direction away from the hook against the spring force of the spring means, insert the pin completely into the center hole. Providing and then relative displacement of the base frame in the direction in which the hook approaches the pin based on the spring force of the spring means, thereby engaging the hook with the end flange of the bobbin.

After surely engaging the handling device with the bobbin in this manner, the balancer arm is turned on to raise the handling device holding the bobbin together with the balancer arm under the action of a balance load. The base frame is substantially suspended from the balancer arm based on its pivoting movement about the pivot axis to the balancer arm, resulting in a pin and,
The bobbin in which it is inserted is in a substantially horizontal position.

The weight of the bobbin thus lifted is supported by the hook through the end flange, and the pin which is inserted into the center hole of the bobbin and is in the position close to the hook is Since the bobbin tilting on the hook is effectively restrained by the interference with the peripheral surface of the center hole, the bobbin is sufficiently stably supported by the handling device.

Further, the bobbin in a substantially horizontal position is provided with a required height under the action of the balancer arm.
Displace to the required horizontal position, and then operate the handle of the device to fit the center hole of the bobbin on the side of the rack opposite to the side into which the pin is inserted. In this case, when the support rod and the bobbin center hole are not pre-aligned with each other, the base frame is rotated about the axis orthogonal to the pivot axis of the bobbin by the action of the support means so that the bobbin center hole is not aligned. By changing the center hole position in the horizontal plane, an approximate alignment state between them is brought about, and then the above-mentioned fitting is performed.

Thereafter, the balancer arm is deactivated, the bobbin is supported by the lateral support rod of the rack as a shoulder, and the base frame is lowered relative to the pin, whereby the hook and the end of the bobbin are lowered. The engagement with the partial flange is released, and the pin is pulled out from the center hole of the bobbin while maintaining this released state, whereby the work for the bobbin is completed.

Thus, here, the bobbin can always be held properly under the action of the hooks and pins of the device, irrespective of its weight, and a special bobbin position change is possible. The link mechanism, the driving means, etc. are not necessary at all, and further, the bobbin can be reliably held as long as the pin can be inserted into the bobbin center hole.

In this device, if at least one handle provided on the base frame is provided with a switch for controlling the operation of the balancer arm, various operations can be performed efficiently without releasing the handle. Can be done well.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a vertical sectional view showing an embodiment of the present invention, and FIG. 2 is a plan view thereof. Here, one end of a base frame 4 is pivotally supported by a bracket 2 provided at the lower end of the balancer arm 1 by a hinge pin 3 extending in the horizontal direction, and the lower surface of the other end of the base frame 4 is shown by a virtual line in the figure. , Hook 5 that engages the end flange f of the bobbin
To provide. This hook 5 is provided to provide stable holding and support of the end flange f, and thus of the bobbin.
As shown in plan view in FIG. 2, the end flange f has an arcuate length sufficient to contact over the required angular range.

A rigid pin 6 having a required length and diameter is provided at the intermediate portion of the base frame 4 so as to project toward the lower surface of the base frame 4 and be displaceable in a direction toward and away from the hook 5. To do. For this reason, the pin 6 in this example can be accommodated in the elongated hole 7 provided in the base frame 4 in the base frame 4
The upper end of the slider 8 is screwed onto a slider 8 which is displaceable along. By the way, the slider 8 here has a vertical cross-sectional shape as shown in FIG. 3 (a), which is substantially cross-shaped as a whole, with its legs on the elongated hole 7 and both arms on the base frame. The arm portions and both side surfaces of the upper portions thereof are slidably contacted with the respective guide plates 9 fixed on the base frame, while being positioned.
Further, by fixing the top plate 10 hung over both guide plates 9 to the guide plates 9 and surrounding the slider 8, it is possible to smoothly move in the elongated holes. Note that FIG. 3B is a bottom view of the slider 8, and 11 in the drawing indicates a screwing hole of the pin 6.

Further, here, in order to constantly urge the pin 6 toward the hook 5, a partition wall 12 is provided at a position between the guide plates on the base frame, and spring means is provided between the facing surfaces of the partition wall 12 and the slider 8. 13 is provided. Here, as the spring means 13, in addition to metal springs such as coil springs,
A rubber, a rubber-like elastic member, a gas-filled spring, or the like can be used. When the compression coil spring is used, the compression coil spring is compressed around the guide rod 14 fixed to the partition wall 12 and extending horizontally. A coil spring is provided, and both ends of the coil spring are seated on the partition wall 12 and the slider 8, respectively, and a small hole 15 for allowing the guide rod 14 to enter is provided at a position of the slider 8 corresponding to the guide rod 14. According to this, when the slider 8 is displaced, the guide rod 14 guides not only the expansion and contraction deformation of the coil spring but also the displacement of the slider 8, which makes the slider 8 smoother. Such displacement will be guaranteed.

Further, on the upper surface of the base frame 4, there is provided one handle 16 which is located near the hook 5 and projects substantially in the longitudinal direction of the base frame 4, and from the top plate 10 above the base frame 4. Another handle 17 protruding in a direction substantially orthogonal to the axis is provided, and preferably at least one of these handles, that is, the handle 16 in the figure, is provided with a switch 18 for controlling the operation of the balancer arm 1. , When the balancer arm 1 is displaced upward, a balance load that substantially cancels the load acting on the balancer arm 1 is applied to the balancer arm 1, and the balance load to the balancer arm 1 is caused by the OFF operation of the balancer arm 1. To stop the action of.

In addition, in this example, of the base frame 4,
At the pivot end of the balancer arm 1 is provided a support means 19 for pivotally supporting it about an axis BB orthogonal to its pivot axis AA. This support means 19 here is an arm 20 whose tip is pivotally supported by the bracket 2.
A shaft portion 21 that is integrated with the shaft portion 21, a rising end wall 22 of the base frame 4 that allows the shaft portion 21 to penetrate, and a shaft portion 21.
Of the retaining nut 23 from the rising end wall 22 and preferably a bearing member arranged around the shaft portion 21 in the rising end wall, more preferably in addition to this, a rear end flange 24 of the arm 20. And a sliding contact member interposed between the rising end wall 22 and the rising end wall 22. Therefore, here, the base frame 4
Is indirectly pivotally supported on the balancer arm 1 via the shaft portion 21 and the arm 20. Here,
It is also possible to provide the rotation support means of the base frame 4 on the balancer arm side with respect to the pivotal support position of the base frame 4.

With the apparatus configured as described above,
To mount a bobbin with a relatively heavy end flange vertically arranged on a support base, for example, a bobbin wound with a steel cord, in a horizontal position on a rack with a support rod, use the balancer arm 1. While lowered to a desired position, the handles 16 and 17 are operated to insert the tip of the pin 6 into the small-diameter center hole of the bobbin 6 as shown in FIG. , That bobbin b
On the other hand, the base frame 4 is horizontally displaced relative to the spring force of the spring means 13 in the direction in which the hook 5 moves away from the pin 6, whereby the bent tip edge of the hook 5 is moved to the position shown in FIG. As shown in b), the bobbin b is sufficiently displaced to the outer peripheral side of the flange f. Since the bobbin b has a weight much larger than the spring force of the spring means 13, the bobbin b is supported by the bobbin b when the relative displacement between the hook 5 and the pin 6 is brought about. There is no risk of moving or falling on the table.

Furthermore, while maintaining the relative displacement state where the hook 5 is separated from the pin 6, in other words, in a state where the risk of interference between the hook 5 and the end flange f is sufficiently removed, the pin 6 is removed. , Is completely inserted into the center hole of the bobbin b, and then the base frame 4 is returned to the original position based on the spring force of the spring means 13, whereby the hook 5 is attached to the lower surface of the end flange f of the bobbin b. Engages securely to ensure proper retention of the bobbin, regardless of the bobbin weight and center hole diameter of the bobbin b.

After that, while holding the handles 16 and 17 of the device as they are, the switch 18 provided on one of the handles 16 is turned on by, for example, operation by the thumb to bring the balancer arm 1 into operation. The bobbin b held on the device is lifted with it under the action of the balancer arm to the required height. in this case,
The base frame 4 rotates about the hinge pin 3 with respect to the balancer arm 1 as shown in FIG.
Is in a balanced posture as shown.

The tilting of the bobbin b with respect to the apparatus, or the drop from the bobbin b under such a balance posture, as described above, causes the hook 5 to engage the bobbin flange f and the pin. 6 and the peripheral surface of the center hole of the bobbin b are sufficiently prevented.

Then, thereafter, as shown in FIG. 6, the bobbin b is moved to a position of a required lateral rod r of the rack s with supporting rods, and there, a center hole of the bobbin b in a sufficient lateral position is provided. Is fitted to the rod r. In this fitting, when the center axis of the bobbin center hole is swaying in the horizontal plane with respect to the center axis of the rod r, the swaying is corrected under the action of the supporting means 19 so that The fitting can always be smooth and easy.

After fitting the center hole of the bobbin b to the rod r in this way, the hook 5 and the bobbin flange f are operated under the condition that the switch 18 is turned off to stop the operation of the balancer arm 1. By releasing the engagement with the pin 6 and pulling out the pin 6 from the bobbin center hole, the work for setting the bobbin b is completed, and the same operation is repeated thereafter.

[0023]

As is apparent from the above description, according to the present invention, it is possible to always hold the bobbin properly regardless of the weight of the bobbin.
The bobbin attitude can be changed as desired without providing a special link mechanism and link driving means for changing the bobbin attitude. Further, here, as long as the pin can be inserted, the bobbin can be reliably held even if the diameter of the bobbin center hole is small. Moreover, in this case, since the hollow rubber body for holding the bobbin is not required, it is possible to sufficiently eliminate the risk of puncture of the hollow rubber body and other troubles.

In this device, when a switch for controlling the operation of the balancer arm is provided on at least one handle, the operation of the balancer arm can be switched without releasing the handle, and the work safety can be improved. Of course, various operations can be performed continuously.
And it can be done efficiently.
