Description

[Detailed Description of the Invention] Technical Field The present invention provides a pair of gripping bodies on a machine frame with at least one of them having a combined action and a wire gripping capacity between the two, and a state in which these leg gripping bodies grip the wire. This invention relates to a wire insertion/removal mechanism for making a wire application and extraction/extraction operation sound in a wire towing willow that pulls the entire wire by moving in the direction of wire extension.

OBJECTS The object of the present invention is to provide a wire insertion/removal mechanism for a novel wire willow that allows wire insertion/removal operations to be performed with one touch and with certainty.

EXAMPLE Hereinafter, an example in which this light is applied to a wire willow will be described based on FIG. 1111.

As shown in Figures 1 to 6, the case 1 of this wire willow is made up of two case plates 2 of similar shapes, and the ceramic case plate 2 has a front bolt 3, an upper hiss 4, and two case plates. It is assembled by a rear hissing member 5.

As shown in FIG. 2, a front opening 6 is formed on the front side between the case plates 2 on the upper surface of the case 1, and a rear opening 7 is formed on the rear side.

As shown in FIG. 4, the front port 3 includes a collar 3.
A hook 8 is rotatably supported through the a f, and its tip is exposed to the outside of the case 1 through the front opening 1. Therefore, during towing work, as shown in FIG. 1, the wire willow can be conveniently used by hooking the hook 8 to any desired location at the work site.

As shown in Fig. 3.5, a support arm 9 is rotatably supported on the front bolt 3 on the side of the hook 8 as shown in the bore in FIG. The forward operating lever 10 is pivoted by a support shaft 11 protruding from both outer sides of its base fiI1.

The forward operation lever 10 has a thick wall portion 12 on the proximal end side and a handle fitting portion 13 on the distal end side, and the thick wall portion 12 is provided with a wire insertion hole 14 (see FIG. 3). Further, the tip of the handle fitting right portion 13 protrudes from the front opening 1 to the outside VCC of the case 1. The internal mechanism of this willow is symmetrical.

The thick portion 12 on the upper image side of the support 111111
Long and short connection pins 15 and 16 are provided on the outer legs of the legs, respectively, and the long connection pins 15 on the side of the handle attachment part 13 are provided with external support plates as shown in Figure 4 VC'). 1
7 are connected to each other at the front of the case 1, and their rear ends extend along the inner wall of case 1 toward the inner edge. Therefore, when the forward operation lever 1u is rotated and maintained, the external support plate 17 is reciprocated back and forth along the longitudinal direction of the case 1 due to the reciprocating movement V of the long connecting pin 15.

Internal support plates 18 are superimposed on the inside of the J and UVC external support plates 17 shown in FIG.
It is connected to the short link bottle 16 of No. 0. Elongated holes 20 extending in the longitudinal direction of the case 1 are provided at the front ends of these internal support plates 18, and inside these elongated holes 20 are front guides fixed between the peripheral outer support plates 17. A bottle 21 is inserted. In addition, a kite piece 2 is provided at the rear of the internal support plate 18.
A rear guide pin 23 (see FIG. 4), which is formed inwardly from the rear end portion 1 of the external support plate 17, is engaged with the upper edge thereof. It is now possible to do so. Therefore, when operating the lever 10 during the forward operation 1', the internal support plate 18 is guided by the longitudinal guide bins 21 and 23 through the connection arm 19, and the external support plate 17 is It is reciprocated back and forth in the opposite direction.

Support bins 24.25 are fixed to the rear sides of both the inner and outer support plates 18.17, and a front clamping device 26 is attached to the support bin 24 between the inner support plates 18.
In addition, the support bins 25 between the external support plates 17 are provided with the support clamp devices 21 arranged one by one. Next, I will explain the constituent sounds of the clamp devices 26 and 27. Since both clamp devices 1i26 and 27trf have the same structure, I will explain the components of the rear clamp device 27 according to Fig. 7. do.

A pair of levers 28 are rotatably supported by the bottom part of each bin 25 on the inner side of the outer end of the support plate 17, and the upper part of these levers 28 An upper bin 3u is extended between the upper bin 3u and a rotatable VC.
It is inserted. From there, the support bin 25 and the upper bin 3u
The surface line connecting the valley axis of the intermediate bin 32 is the intermediate bin 32.
forms an obtuse triangle with its axis at its apex.

On the inside of the valley lever 28, a side plate 33 of similar metal engravings is supported on the upper part bottle 30, and the intermediate bottle 32 is fitted and pressed in the vertically intermediate part thereof. - A pair of front and rear caulking pins 35 are inserted between the lower ends of both side plates 33, while a circular arc-shaped long hole 34 is formed therethrough. And these picture side plates 33
A pair of upper and lower gripping bodies 36 and 37 facing each other are arranged along the wire extending direction, and the upper and lower gripping bodies 36 are connected to the intermediate bin 32vC1 and the 37th gripping body 37N.
The gripping body 3 is inserted into and supported by the first tightening bottle 35, respectively.
Opposite ends of 6 and 37 [111 have semicircular recesses that approximately correspond to the diameter of the wire! 38.39 are formed.

Therefore, this lever clamping device 27 has a lever 28.
The first parallel interlocking mechanism is connected by four support bins 25 and ceramic intermediate bins 320, each having different parallel interlocking points; The upper gripping body 36 is supported by the intermediate joint of the first parallel interlocking mechanism, and the lower gripping body 37 is moved through the side plate 33 to perform a second horizontal movement. Supported by the mechanism's mediating clause. As both levers 28 are tilted, the upper gripping body 36 and the lower gripping body 37 are moved parallel to each other along the wire learning direction while facing each other, and as a result of the parallel movement, the upper gripping body 36 and the lower gripping body 37 are As described, the recesses 38 and 3 of the image grips 36 and 37
The spacing between the 9's is enlarged or reduced.

Finally, the extraction clamp device 2 configured with VC as described above.
The effect of No. 7 will be explained.

FIGS. 8 and 9 are schematic diagrams showing the movement of the rack part clamping device 21, and each burrow and worm are labeled with a symbol corresponding to the bottle described above. Therefore, consecutive W□ points 25,3
The straight line connecting 2, 32.25 is the first parallel interlocking mechanism
, and the page 1 line connecting the joint points 25, 30° 30.25 indicates the second parallel interlocking mechanism Y. Reed 7c, 25-30-3
A pair of obtuse triangles connecting 2 are located at the lever 28, and 3
5-30-30-31- The rectangle that connects is the side plate 33. Then, the straight lines connecting 32-32 and 35-35 point to the upper gripping body 36 and the lower gripping body 3γ, respectively.

In the figure, reference numerals 51 and 52 are tentatively written front and abutment levers, which are biased toward both levers 28i.

Now, FIG. 8 shows that the first parallel interlocking mechanism X (25-32) is tilted backward, and the second parallel interlocking mechanism Y is tilted backward. 1)
(25-30) are shown in a nearly upright position. In this state, when the 11111 lever 28 is rotated in the direction of the arrow P and the first parallel interlocking node a is approximately erected at J, 9 shown in FIG. The connecting node 30 is lowered by interlocking the circle liU, and the connecting node 3 is lowered by interlocking the circular arc with the radius of VC and lever ai.
2 is rising and leaking.

1. Since the lower grip body 37 held at the equidistant N■ perpendicular position from the joint point 30 is lowered, the upper grip body 36 is raised, so that the upper and lower grip bodies 36, 37 The spacing between the awns expands.

Also, in this state, the lever 28 rotates in the direction of arrow Q,
When the second parallel interlocking jWJb is almost straight V, each circular arc interlocking causes the ↓union joint point 30 shown in Fig. 8.
As the sky rises, the point J32 falls. Therefore, the upper gripping bodies 36 and 37 move toward each other by V, and the distance between them is reduced again.

Based on the above-mentioned function 1, the gripping and releasing operation of the wire at the rear clamp device 27V is performed in the 15th step.
．． To explain according to Fig. 16, Fig. 15 shows upper and lower III
A wire W of a predetermined wire diameter is inserted between the recesses 3B and 39 of the I gripping body 36 and 37. At this time, the Ir1il lever 28 is moved between the support bin 25 and the upper bin 30.
Since the page line connecting the two wires is held in a state substantially orthogonal to the direction in which the wire W extends,
, 37 are closed, and the rear clamp device 27 is in a gripping state.

In this state, by moving the lever 28 fully in the iJ direction, the support don 25 and the intermediate bin 3 are moved as shown in FIG. 16.
2, the vertical grips 36 and 37 are opened and moved in the direction that separates them from each other, and the distance between the four parts 38 and 39 is adjusted as described above. is larger than the wire diameter of wire W17). Therefore, the rear clamp device 27 is in a released state in which it does not grip the wire W.

As described above, the configuration VC twist of the clamping devices 26 and 21 of this embodiment is such that the vertical gripping bodies 36 and 37 are respectively provided at the mediating joints of two sets of parallel interlocking mechanisms having different lever lengths.
As the lever 28 swings, it is opened and opened up and down parallel to each other, so that the inner part of the concave portions 38 and 39 at the bottom and the wire W are closed. ) 11 is '6! Being looked after is powerful f! , you can get the full gripping force. 711, the upper leg 4'f bodies 36 and 37 are opened and closed in different directions, and the lever 28 is slightly tilted [↓
Therefore, since the gripping bodies 36 and 37 have a large movement difference, the length of the lever 28 can be shortened and the tilting angle of the lever 28 can be made small, so that the entire clamping device can be constructed in a completely compact manner.

′! In addition, in the clamping device 26, 27 of this embodiment, the lower gripping body 37 is moved parallelly downward from the side plate 33V to the first parallel interlocking joint X. Compared to the case where the wire W is directly supported on the medial part), is the position of gripping the wire W from the upper gripping body 36 and the VC inside or outside? -! The f plates 18 and 17 sides VC and r approach each other. Therefore, the bending moment l- acting on the lever 28 and the inner support plate IB and 17VC due to the gravity of the heavy object R is reduced, and the bending of these valleys during towing work is prevented. Tomogata is original V
It is possible to prevent c.

Note 1. In the image clamping device 1i26°21 shown in Figure i@4.5, the wire W is not pushed in, so the inspection lever 28 is tilted backward vc from the gripping state described above. 6 As shown in Figure 6, the facing grip body 3
B, The 37 nu' proximal bloods are joined to each other.

By the way, the front and rear 11111 clamp devices 26.27 are used not only for gripping 2 and releasing fμ of the wire W created in accordance with vAa of the lever 28, but also for both gripping bodies 36.3.
7 are mutually closed and in the fc gripping state, a permissible counter-return action is performed in which the forward movement of the wire W is enabled and the backward movement is disabled.

Therefore, these internal effects will be explained based on FIG. 1O. For the sake of explanation, this figure shows the rear club device 27 in a vertical position, and the lower end VC#Sc of the inserted wire W is fixed. Both levers 28 are held in a state that is orthogonal to the straight line connecting the support bin 25 and the upper bin 30 to the study direction of W, W, and (W), and a wire is held between the holding bodies 36 and 37. The grip of W is broken.

Assume now that the clamping device 27 at V is fixed. In this state, when an upward force is applied to the wire W, this sword is moved to the gripping body 36, 37c/3 valley concave w3s,
The L downward gripping bodies 36, 37 are slightly lifted by the friction between the inner recess 3s and the outer circumference of the wire W, and the lever 28 is slightly tilted counterclockwise in the a1 direction. Therefore, the ceramic gripping bodies 36 and 37 are in a state where they do not grip the wire W2, so that the wire W can move upward even though the clamping device 27 is broken in its gripping state. Also, does the wire W move? If a downward force is applied to the clamp device 27 in the state where the vcIT 111 is not attached, the gripping bodies 36 and 37 of the vcIT 111 will be
Then, the wire Wy is no longer gripped, and the clamping device 27 can be lowered. That is, the clamping device 27 can correct the relative forward movement of the wire W in the gripping state, and based on this permissive action, the forward traction 1' of the wire W, which will be described later, is performed.

On the other hand, when both grippers 36 and 37 are gripping the wire W, the friction between the wire W and the valley recesses 38 and 39 causes the gravity of the heavy object H to move the leg gripper 36 and 37i downward. As a result, the distance between the gripping bodies 36 and 37 is further reduced, and the wire)
8. Strongly grasped by 39 questions. Therefore, the backward movement of the wire W with respect to the clamp device 27 is prevented, and the wire W is prevented from falling off due to the non-returning action of the cigarette during towing work. IJ: I can do that.

Next, both clamp devices 26 and 27 and the backward operation lever 4
The articulation extraction with 0 will be explained.

The end portion is rotatably supported by the upper bin 30 on the rear side of the front clamp device 26, and its tip handle sleeper portion 41 is protruded to the outside from the AiJ portion opening 6 of the case 1. ing. After this backward operation, the bottle 42 which is pushed through and fixed to the proximal end of the cylinder (Kf) is supported by a pair of connecting links 43, the ends of which are shown in FIG. 27 is connected to the upper bin 30 on the rear side. Therefore, as shown in FIGS. 15 and 16, when the retraction operation lever 40 is rotated, the front compartment clamping devices 26 and 27 move toward and away from the house through the entire connection link 43. It has become.

An engagement groove 45 that engages with the rear surface of the base end of the reverse operation lever 40 is formed in a diagonal manner. Therefore, when the reverse operation lever 40 is tilted forward as shown in FIG. ↓, the reverse operation lever 4U does not tilt forward any more than J: and is regulated as shown in Figure 14.16.
When the lever 40 tilts backward and breaks, the upper end of the retaining surface 45 engages with the rear surface of the proximal end of the lever 40.
Reverse operation 1': The lever 40 is restricted to prevent it from tilting further backwards.

As shown in FIGS. 3 and 6, the front and rear ends of the meat iron 4B are provided with sleeves 49 and 50, respectively, and the stopper rod 48 is provided with these stoppers 49. The front spring 51 and the strength spring 52, each serving as a biasing class, are fitted with a length of 7''L in a state where one end has not been positioned.

In addition, on both rods 48 [i is a spring storage plate 53 with a bent shape that is bent so as to accommodate the clamping spring 52, and a spring storage plate 53 with an 8-movement function is provided. At the rear end IIJ, a set lever 54 is shifted to the right with its rear end bent portion protruding from the upper open lower portion of the case 1 at a t portion VC. A locking pin 56 that can be used for double-crossing is fitted into a locking recess 55 formed on the rear edge 8 of the case 1 in the middle of the set lever 54. is finger rest 1s5

are four wire introduction parts formed at the center of the edge of the case &2, and are shaped into a wire introduction port 62 when both case plates 2 are aligned. Then, the VC is introduced into the case 1 from the inlet 62 of the wire W, and each gripping body 36 of the technique part and front clamping device 27,26,
37, the wire passes through the wire hole 14 of the forward operating lever 10, and is guided out of the case 1 from the guide gutter 60.

This concludes the explanation regarding the structure and function of the neck in this wire tugging machine. Next, the operating force of this wire tensioning machine will be explained in the following order: push-in operation, forward operation, and backward operation of the wire.

First, based on Figures 12 and 13, we will explain the I/C when pushing the wire W against the wire i''f pulling*. 5T
While resisting the spring force of the backward compression springs 51 and 52, pull the set lever 54 backward,

11 lever 28 is tilted in the N-1 direction when biting in the figure, and the 10 wire connecting the intermediate bin 32 and the support bin 24 is moved in the direction in which the wire is pushed in. The distance between the recess 38 of the lower grip body 37 and the recess 39 of the lower gripping body 37 is expanded.Then, the front clamp device 26 is in an open state in which wire W=4 can be inserted.

On the other hand, both /<-28 of the plate clamp device 27 are connecting links 41? : Since it is pushed and tilted in the anti-training direction, both the gripping bodies 36 and 37 on the left side are released, as in the case of the front clamp device 26. In this way, both clamp devices 2
6. With both 27 open, insert the wire W into the case 1 through the insertion hole 62, and move the rear clamp device 27 and the front clamp device 26 forward to tighten /N-10. After the wire hemostasis hole 14 is pushed back, the wire is led out of the case 1 through the guide 6U.

Then, while resisting the springs 51 and 52 VC, pull the set lever 54 all the way and the locking pin 56 fully locks in the locking recess 55, as shown in Fig. 13. As the retraction operation reno \-40 moves away, each renomer 28 of the one-socket clamping device 26.27 is moved in the training direction (as shown in the figure), so each support bin 24.25 and upper bin 30 A straight line connecting the wires is cut in the direction of extension of the wire (2), and the upper and lower gripping bodies 36.37 are respectively moved to the closed position.Then, the front clamping devices 26.27 move to a gripping state, and the pushed-in wire W is set in a state where it will not come out.

Next, the advancing operation of the wire W will be explained according to FIGS. 1, 13 and 14.

Now, Figure 1 shows this wire tensioning machine mounted on an inclined surface ("

That is, as shown in FIG. 13, both the gripping bodies 36 and 37 are closed by the spring force of the springs 51 and 52, and the seven gripping states V are held.

In this state, if you want to move the wire W forward and pull it up, use Figure 1, 1/1. 1
Advance operation 1z Fits into bar IU. When the operating handle 58 is rotated toward the forward position, the forward operating lever 10 is connected to the external support plate 17 via the long connecting pin 15.
At the same time as the connecting arm 19 is moved backward, the internal support plate 18 is also moved forward. Then, 71 of these
As the tlX support plate 18 works, the front Franz device 26 is moved forward, and the wire W held between the upper and lower gripping bodies 36 and 37 is pulled toward the wire 81''.

At the same time, as the rear support plate 11 moves backward, the rear clamp device 21 moves rearward while allowing the wire W to move forward 8 times based on the above-mentioned permissive action. Then, with the front guide pin 21 fixed to the outer support plate 11 in contact with the rear edge of the elongated hole 20 of the inner support plate 18, the rotation of the forward operation lever 10 is stopped. hand,
The spacing of the image clamping devices 26,27 is increased. In addition,
At this time, the movement of the plate clamping device 21 is caused by the backward operation lever 40, and the movement of the connecting link 43 is followed by the operation of the connecting link 43, so that the plate clamp device 21 is tilted rearward.

Finally, in this state, when the operation pan 1 - 5B is rotated 1'L toward the front, the temporary clamp device 27 is moved forward together with the external support plate 17, and at the same time, the internal support &18 At the same time, the front clamp device 26 is temporarily retracted. Therefore, in a state where the wire W is held between the N grips 36 and 37 of the rear clamp device 21, and in a state where the front clamp device 26V( .Stiff, Misao f

The operation of moving the wire W up and down will now be explained based on FIGS. 15 and 16 VC.

When retracting the wire W, the operating handle 58 is fitted onto the retracting operating lever 40, unlike during the cutting operation.

As shown in FIG. 15, when the handle 58 is rotated backward from the non-shocking 1' position shown by the chain line, the rear clamping device 27 in the gripping state is rotated. When the leg lever 28 is held in a state where it cannot be tilted any further, the retraction lever 40 is rotated around the bin 42 tray, and the bIJ section clamping device 26 is tightened.
Tilt both levers 28 forward. Once the support bottle 24 and the opening bottle 32 are connected, the top gripping body 3 is placed almost upright with respect to the direction of the wire W connecting the support bottle 24 and the opening bottle 32.

8. The distance in the 39-direction is too large, and the front clamp device 26 is in a released state in which it does not grip the wire W.

Therefore, the power supply clamping device 2 held in the gripping state
Since the gravity of the heavy object R acts on the wire WLa
, the power supply clamp device 2γ was designed for the reverse operation as described in mir.
It is strongly gripped between the two gripping bodies 36 and 37.

As indicated by the arrow in the figure, when the masterpiece handle 58 is rotated backwards in this state, the lever 28 for the n11 section clamping device 260 cannot be tilted any further in the h1'' direction. Due to the rotation of the backward operation lever 40 centered around the bin 30, the connecting link 431C is pushed and broken, and the rear clamp device 27 is moved backward while gripping the wire W, and at the same time, the backward operation lever centered around the bin 42 is moved back. The pivoting movement of 40 advances the front clamping device 26 in the open position. Then, the wire W is transferred to the friend side by one predetermined route. At this time, the inner support plate 18 is moved forward and the inner support plate 18 is moved forward and the front and rear levers 10 are rotated in response to the rear lamp assembly +&26.27. be moved.

When C is rotated, the front clamping device 26 is moved back through the upper bin 30 as shown by the arrow in the figure, and the (support) clamping device 27 is advanced through the connecting link 3. . Therefore, the wire W is connected to the glaze clamping device 26.
The robot is transported backwards while being held by the robot. In this way, the operation handle 58 continues to be turned to fJil&l! l! J movement 1
If this is done, the wire W can be lowered along the rectangular object Rk while feeding it backwards V (one direction).

This concludes the explanation of the operation of these four wire kens. According to this operating force method, the operating handle 58 can be attached to the forward and backward 1l11 1' handles 10.40 alternatively, so that the traveling direction of the wire W can be adjusted automatically. Since the decision is made, a special switching mechanism is not required and the configuration is simplified, and erroneous operations can be avoided and millet mixing can be carried out accurately.

6 and 37, and in the clamping devices 26 and 27, the image gripping bodies 36 and 37 are attached to the wire Wc.
/) Ensure that their return movements after all movements are made. Therefore, the wire W is prevented from being completely disposed of or falling off in such a case, and the pole towing work, which tends to be dangerous, can be safely carried out.

This wire towing machine is not a fortune-telling moat, but in addition to the above-mentioned towing work on the slope entrance, it can also be used for lifting and lowering the front tray vertically, and for towing heavy objects horizontally. It can be used in a variety of other work methods, such as when performing a position check when installing machinery, etc.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and in one example, one clamp device is held in a fixed state, and the other clamp device is reciprocated to pull the choir. 1, or it may be required for a four-way head-mounted wire swing machine with only a forward operating lever, or the structure and shape of the valley may be changed without departing from the spirit of the invention. Change it to Shiji and make it concrete J-Rokotomo-oJ
It is Noh.

Effect u-ii-1: As described, the present invention is applied to the frame of four wire pullers, operatively connected to a movable gripper,
Between the legs and the support body when pushing the wire in? Recession 1
- It moves with manual operation between the N position and the set position where the N gripper makes a sound when towing. When the holder is in the set position, a part of the member engages and the holder is fully provided to hold the member in the set position. Since it can be done with one touch and reliably, it is possible to use a wire extrusion machine (industrial as a cylinder;
” This is a useful invention.
