Description

[Detailed description of the invention] (Technical field of the invention) The present invention is a binding consisting of a long binding band, an opening through which the band is inserted, and a stopper formed with a locking claw on the opposite wall surface of the opening. Using a tool, feed the band through the opening of the stopper, wrap it around the object to be tied, and then tighten the tip of the band again.
It relates to a binding machine that binds objects such as electric wires by inserting the band into the opening of the stopper, pulling back the excess band at the proximal end to tighten the band, and then cutting the band near the stopper. The present invention relates to an actuating device for a mechanical part related to operation.

Conventionally, this type of tying machine uses a tying tool in which the tying band and the stopper are separate parts.The conventional method is to insert the tying band through the stopper, make it go around the object to be bound, and insert the tip of the band into the stopper. There are some cases in which a series of steps are performed manually, but in order to automate the entire bundling work including the above steps, the following additional mechanisms are required.

That is, in order to guide the binding band around the object to be bound and to guide the tip of the band that has circulated toward the opening of the stopper, the band is movably interposed in the band travel path between the object to be tied and the stopper. an inner guide member and its operating mechanism; a stop feed mechanism with a feed pawl that reciprocates so as to continuously feed the stoppers to predetermined positions; A mechanism or the like is required to move it between the two positions.

It is essential that the inner guide member be retracted from the band travel path when tightening the band.
In addition, unless the stopper is configured to move as described above, problems will occur such as the stopper getting caught in the locking claw of the stopper and hindering the running of the band, or insufficient band tightening force. Therefore, when such a moving configuration is adopted, it becomes necessary to accurately set the timing of movement and supply of the stopper or the timing of retraction of the inner guide member.

For this reason, if means for driving each of the above-mentioned mechanisms were to be provided independently in the binding machine, the binding machine would become larger and heavier, making it difficult to handle and causing problems such as the inability to work in narrow spaces. .

In particular, the band is guided along the guide grooves 3a, 2a of the band, and in particular, the tip portion 4a of the band that has entered the delivery port 33 is forcibly bent in its running direction so that it does not go straight and come into contact with the object to be bound. , serves to positively direct the tip end 4a of the band returned in a loop toward the stopper 16.

The inner guide member 45 can be retracted from the guide position where it acts as described above in the lateral direction with respect to the band running path S, as will be described later, and is retracted from the guide position at least before the band tightening operation is completed. It is structured as follows.

A cutter 65 is attached to the free end of the lever, and the cutter 65 is normally held in place by a stopper 68 against the bias of a coil spring 67. held in the working position. In addition, the cutter support lever 66
corresponds to the cutter operating lever 70 via a cam roller 69 attached thereto, and the lever 70
is pivotally supported by the main body 1 and connected to a cutter actuating air cylinder 71.

In FIGS. 3 and 4, the binding tool used here is partially enlarged, but as shown in FIG. 3, the band 4 has locking teeth along the longitudinal direction on one surface. 4b is formed into a loose shape, and ribs 4c having the same height as the teeth 4b are formed along both side edges.

As shown in FIG. 4, the stopper 16 is connected by a web 16a that is easily broken, and has an opening 72 formed in the center thereof, which serves as a band insertion hole, passing through the band in the running direction of the band. Locking pawls 16b are integrally formed to protrude from the upper and lower opposing wall surfaces that partition the . The band 4 and the stopper 16 are manufactured, for example, by integral molding of a synthetic resin using a molding method such as extrusion or injection molding.

Next, a series of binding operations by the binding machine will be explained with reference to FIGS. 5 to 11.

In FIG. 5, when objects W to be bound such as electric wires are placed in the binding position 8, first, for example, by actuating a trigger lever (not shown), the actuating cylinder 7 is moved to the left to release pressurized air from the air chamber 14a. The outflow moves it from the inactive position to the first active position.
That is, the piston 10 moves to the left under the force of the spring 11, but the slider 12
It stays in the position where it touches 3. As a result, the movable jaw 3 is rotated from the open position to the illustrated circumferential guide position via the operating link 6, and both the jaws 2 and 3 position the guide grooves 2a and 3a in an annular shape around the object W to be bound.

Next, the motor 24 is driven to rotate forward in the feeding direction,
The band 4 is advanced along the band travel path S from the standby position A via the drive pulley 21 and the like. The band 4 is inserted from the guide frame 17 into the opening 72 of the stopper 16 supported in the support recess 18 of the slider member 15, and is guided in movement by the upper and lower band guide members 34, 35 in the intermediate region M, and further advances. and enters the delivery port 33.

An inner guide member 45 is interposed in front of the delivery port 33 so as to be positioned exactly on the band traveling path between the object W and the band. Therefore, the leading end portion 4a of the band is guided in the regulated band feeding path by the upper guide surface 45a of the inner guide member 45 in the guiding position, and is guided around the object W to be bound along both the jaws 2 and 3. go around,
When the distal end portion 4a returns to the delivery port 33 again, it is guided in the band return passage by the lower guide surface 45b of the inner guide member 45, and is further moved to a nearby position just before exiting the delivery port 33 and entering the stopper 16. reach. Here, again the upper and lower band guide members 3
The return of the band tip member 4a is detected by the band guide member 35, which is guided by the band guide members 4 and 35 and also serves as a sensor lever. to the second operating position shown.

That is, the pressurized air is transferred to the right air chamber 14b.
is attached to the slider 1 along with the piston 10.
2 also leaves Rod 13 and moves to the left. As a result, the movable jaw 3 further rotates to the push-in position, pushes the tip end 4a of the band into the opening 72 of the stopper 16, and locks and fixes it there with the locking claw 16b of the stopper 16.

In the above operation, as shown in FIG. 7, when the band 4 moves forward along the arrow F, it passes through the center position XX which is equidistant from the upper and lower locking claws 16b of the stopper 16. , guide frame 1
7 to the vicinity of the stopper 16, both locking claws 16 protrude in the opposite direction to the forward direction F.
Interference with b can be avoided. Furthermore, in the intermediate region M that protrudes from the stopper 16 toward the inner guide member 45, the pair of band guide members 34 and 35, which serve as guide means, guide the band 4 as described above.
During forward travel, the band teeth 4b are actively prevented from interfering with the locking pawl 16b, allowing smooth band travel.

Furthermore, when the distal end portion 4a of the band returns along the arrow R to the vicinity of the stopper 16, in order to enter the opening 72 of the stopper 16 from this position, the proximal end portion of the band 4 that has already been inserted must be A forcing force is required to push the band upward, and this force is applied by rotating the movable jaw 3 to the pushing position, and as shown in FIG. Center position
-X, and is deviated upward from the tip 4a to securely engage with the corresponding locking pawl 16b. Then, the tip portion 4a no longer comes out of its locked position.

Note that the stopper support recess 1 of the slider member 15
8 and the upper and lower walls 15 between the cutter insertion hole 19
b, 15c, the upper wall part 15b, that is, the wall part on the side where the base end of the band is pushed up, has a notch 15d so that the base end can easily move upward.
It forms and becomes shorter.

From the state shown in Figure 8 above, point the proximal end of the band to arrow P.
By pulling back along the band 4, the tip 4
A remains in the stopper 16 and slides in the locked state, and the band is tightened.

That is, when moving to the operation of tightening the band 4 and tightening it against the object W to be bound, that is, before the band tightening operation is completed, the inner guide member 45 moves from the guide position in the band traveling path S to the position shown in FIG. Evacuate in the direction of the arrow as shown. This retracting operation is performed by moving the engagement end 30b of the drive member 30 from the starting end position of the stroke in the direction of the arrow until it engages with the other end (left end) of the long groove 46 of the slider member 15. During this time, the cam roller 47
engages with the flat cam edge 49b of the lever 48, which acts as a cooperating cam means, to hold the lever 48 in the swinging position against the spring, and between the cam roller 52 and the cam groove 56, which form the actuating connection means. The cooperation causes the guide member 54 to swing, and the inner guide member 45 to avoid the movement. That is, the driving member 30 is
At the beginning of the movement stroke in the forward direction toward the object to be bound W, the engaging end portion 30a relatively moves within the long groove 46 within a predetermined play range, but the slider member 15 remains at the reference position. During this period, the lever 48 swings through the cam means in response to the start of the movement stroke of the drive member 30 prior to the movement of the slider member, and this movement is transmitted through the actuation transmission means. As a result, the guide support member 54 swings. The direction in which the lever 48 swings is the return direction that causes the feed pawl 57 to engage with the next stopper 16, and the direction in which the guide support member 54 swings is the direction in which the inner guide member 45 is retracted.

Since the timing structure is as shown above,
When the slider member 15 starts moving forward, both the feed pawl 57 and the inner guide member 45 are out of the movement locus, so there is no risk of interference with each other.

Next, when the drive member 30 moves further leftward from the initial movement stroke range, the member 30
engages with the slider member 15 and moves the object to be bound W from the reference position through the intermediate region M to the forward position shown in FIG. The band 4 is driven in the direction shown by and operates to pull back the base end portion of the band 4. As a result, the band 4 is tightly tightened on the object W to be bound.

Note that, as a pre-movement before the slider member 15 moves forward, the movable jaw 3 moves to the open position.
To avoid interference with a loop-shaped band when the slider member 15 moves forward.

Also, due to the movement of the drive member 30, the cam roller 42
10, the lower band guide member 35 rotates via the link 41 and is forcibly retracted to a second position shown in FIG. 10 outside the movement trajectory of the slider member 15. Therefore, the member 35
does not impede the forward movement of the slider member 15 and the stopper 16.

On the other hand, when the slider member 15 moves forward, the upper band guide member 34 moves forward at its front end 15a.
The inclined cam edge 3 formed on the band guide member 34
4d, and its cam action causes the member 34 to spring 34 as the slider member 15 moves.
Smoothly rotate it out of the movement trajectory against the bias of b. The position shown in FIG. 10 is the second position of the upper band guide member 34.

Upper and lower band guide members 34, 35
is also moved out of its trajectory in relation to the forward movement of the slider member 15 as described above.
There is no problem in the movement of the slider member 15.

Further, when the slider member 15 retreats and returns to the reference position, the upper band guide member 34 is moved by the biasing force of the spring 34b, and the lower band guide member 35 is linked to the drive member 30 according to the movement. are returned to the respective first positions by means of a link mechanism.

Prior to the forward movement of the slider member 15, the cutter 44 operates to cut the web 1 of the stopper 16.
6a (FIG. 4), and the stopper 16 supported by the slider member 15 is separated from the following stopper. The operating direction of the cutter 44 is indicated by arrow Q in FIG.
It is shown.

Note that instead of this cutter 44, it is also possible to configure the web to be cut off at the sliding edge portion with the main body when the slider member 15 moves forward, so that the cutter 44 can be made unnecessary.

When the tension of the pulled back band 4 increases and the tightening of the bound object W becomes sufficiently strong, the swing plate 26 is moved via the tension roller 25 against the bias of a tension spring (not shown). When the plate 26 rotates from its original position to a state where a predetermined tightening force is obtained, the leaf spring 2
The sensor 29 is operated via the cutter 8, thereby starting the cutting operation of the cutter 65.

That is, as shown in FIG. 11, the air cylinder 71 is actuated to rotate the cutter operating lever 70, and the cutter support lever 66 is cam operated to operate the cutter 65 from the inoperative position, and the cutter 65 is moved from the inoperative position to the position immediately adjacent to the stopper 16. At the rear position, band 4 is cut from the proximal end.

This cutting loosens the base end of the band, and the tension roller 25 returns to its original position due to the bias of a tension spring (not shown). With this force, the remaining base end of the hand 4 is moved as shown by the chain line in FIG. Retreat to position B shown.

However, at this position B, the tip end 4a of the band
Since it is in a state of interfering with the entry of the next stopper 16, the motor 24 is further driven in the reverse direction to pull the tip end 4a of the band back to the initial standby position A.
Then, the return to position A is detected by the lever 61, and the motor 24 is stopped by the operation of the sensor 63.

Then, by releasing the trigger lever, the driving member 30 is driven by the cylinder 31 in the return direction. As a result, the slider member 15
However, during the initial movement stroke when the drive member 30 returns, the slider member 15 remains in the forward position due to the delayed actuation transmission means, as is clear from FIG. There is. During this time, the cam roller 48 rolls along the flat cam edge 49b, and at the timing when it moves to the cam edge 49a, the slider member 15 begins to retreat, and the inner guide member 45 is moved again without interfering with the slider member 15 due to the action of the spring 50. Return to guidance position. Also, the feed claw 57 moves the next stopper 16,
A spring 50 is attached to the side surface of the slider member 15 that retreats.
When the slider member returns to the reference position and aligns with the recess 18, the next stopper 16 is immediately sent into the recess 18.

As described above, a series of binding operations including guiding and driving the binding tool are automatically performed without intervening operating operations. Therefore, it is easy to incorporate the device into an automated machine in a factory or the like to configure an automated system for bundling.

In the embodiment, the feed pawl 57 is pivotally supported on the lever 48 having the cam edges 49a and 49b, but the inner guide member 45 is provided on the lever 48 side.
It is also possible to easily create a structure in which the feed pawl 57 is provided on the guide support member 54 side.

Alternatively, an opposite configuration may be used in which the cam edges 49a and 49b of the cam means are formed on the corresponding drive member 30 side.

Furthermore, the long groove 40 and the engaging end portion 30b constituting the delay actuation transmission means can also be configured in the opposite manner as described above.
As described above, the present invention is not limited to the embodiments.

(Effects of the invention) As described above, according to the invention, the movement mechanism of the slider member and the movement mechanism of the stopper are required in the automation of a tying machine using a tying tool in which the tying band and the stopper are configured separately. Since the main mechanisms such as the feed operation mechanism and the forward/backward movement mechanism for the inner guide member are driven by a single drive member, there is no need to provide a separate drive source for each mechanism. By including a delay movement in the movement of the slider member, each member does not interfere with each other.
Each member can operate at precise timing, and does not require a complicated mechanism to set the timing of each member, so the structure is simple, compact, and easy to design for automation, as well as reliable operation and low-cost bundling. This is something that can provide opportunities.
