The chain drive splice 8 also has a shaft connected to both sides like the tension roll 26, and the chain 5 has splines 27 provided on both sides of the tension roll 26 and chain drives provided on both sides thereof. The gear formed on the outside of the splice 8 is bitten through the link 34 to rotate.

In addition, the position of the chain 5 can be determined by the sensors 6, 21, 22 of the sensor bracket 25 connected to the chain 5, which is shown in FIG. It is divided into clamping position, unclamping position and standby position.

Clamp portions 7 connected to each other at right angles to both side chains 5 are connected to the chain 5 via a clamp holder 11, and the clamp portions 7 are largely shown in FIGS. 5 to 7. It consists of a clamp holder and a clamp arm.

The clamp holder, indicated by reference numeral 30 in FIG. 4, is composed of sliding blocks 12, 16 and holder plates 31, 32, 33, and the clamp arms have an upper clamp arm 18 and a lower clamp arm 20. And hinges (19-1, 19-2) to move these two arms (18, 20) by connecting, and the two arms (18, 20) are inserted into the clamp holder 30 to be slid The cam 15 and the locking cam 13 that functions as a locking function are connected as bolts.

In addition, as shown in Figure 4, the lower clamp arm 20 is formed with two holes 29 on both sides in the longitudinal direction, from which the sliding bar 14 is coupled by a bolt (not shown) do.

The clamp unit 7 is set to the start of the mailing plate, the completion point, and the standby time, and at the beginning of the mailing plate and the completion of the mailing plate as shown in Figure 4 on the lower both sides (roll length direction reference), for clamp fixing The cylinder 4 is installed so as to be operated at the time of starting the mailing plate and at the time of completing the mailing, respectively, to fix the lower clamp arm 20.

The positions are determined by the sensors 6, 21, 22 detecting the sensor bracket 25 installed in the chain (5).

In addition, the clamp portion 7 moves up and down the mailing table 23-1, 23-2 when its position is moved by the chain 5, so that the mailing table 23-1, 23- is possible. The corresponding part of 2), that is, the entrance part and the exit part 23-1, 23-2 of the tension roll 26 are directly below the strip plate direction by the pneumatic cylinders 24-1, 24-2. The structure is movable, and the chain 5 is rotatable while maintaining a down state during the mail order operation.

Hereinafter, the operation of the present invention having the configuration as described above.

In order to move the clamp portion 7 to the chain 5, the plate tables 23-1 and 23-2 are first down using the pneumatic cylinders 24-1 and 24-2.

When the mailing table 23-1, 23-2 is down, the chain 5 is rotated by using the drive motor 10. Accordingly, the sensor bracket 25 of the clamp unit 7 is connected to the clamp position sensor of FIG. 21, the driving motor 10 is stopped, and the clamping cylinder 7 is operated while the fixing cylinder 4 (the first cylinder of FIG. 3) is operated up from the stopped clamp portion 7. As the cylinder rod is inserted into the hole 29 formed in the lower clamp arm 20 of the clamp portion 7, the clamp portion 7 is fixed in the clamping position (see FIG. 3).

When the clamp portion 7 is fixed in this way, the chain 5 is rotated a predetermined length in the reverse direction of the strip traveling direction.

At this time, the clamping portion (18) and the opening operation of the clamping arms (18) and (20) occur in the clamp portion (7). The clamping arms (18,20) fixed by the fixing cylinder (4) are clamp holders (30; 12, 16). (31), (32), (32) and (33) are upper sliding blocks in the clamp holder (30) while being retracted along the chain (5) by a clamp holder (11) connecting the chain (5) and the clamp holder (30). As the cam 15 of the upper clamp arm 18 slides along the block 16, the upper clamp arm 18 opens upward with respect to the hinge 19.

In this open state, the plate strip S is advanced to deeply insert the script S between the lower clamp arm 20 and the upper clamp arm 18 so as to contact the shaft of the hinge 19.

In the above state, when the chain 5 is moved forward by a predetermined length of the strip using the drive motor 10 of the driving unit, the clamp holder 30 is moved in the strip forward direction by the clamp holder 11 connected to the chain 5, At this time, in the clamp holder 30, the strip S is clamped.

More specifically, when the clamp holder 30 moves forward along the chain 5 with the lower clamp arm 20 fixed, a lower sliding block 12 inside the clamp holder 30 is provided. Is moved downward about the hinge 19 by sliding the locking cam 13 of the upper clamp arm 18, wherein the lower clamp arm 20 and the upper clamp arm 18 are clamped to each other, The strip S between the upper and lower arms 18 and 20 is clamped by the upper and lower arms 18 and 20.

When the strip S is fixed to the clamp portion 7 in this manner, the clamp fixing cylinder 14 which fixed the lower clamp arm 20 is down and returned to its original position, and the clamp portion 7 is connected to the chain 5. When the chain (5) is driven by the drive motor 10 in the strip (S) is rotated along the chain (5) with the rotation of the splice (27) connected to the roll neck to the bearing (28) strip (S) 3) is advanced along the predetermined chain 5 to the unclamping position of FIG.

At this time, the tension roll 26 does not rotate, so only the splice 27 installed on the roll neck is rotated by the bearing 28 so that the chain 5 does not rotate during the operation.

When the clamp portion 7 comes to the unclamping position of FIG. 3 along the chain 5, the sensor 22 is sensed through the sensor bracket 25, at which time the clamp portion 7 stops.

When the clamp unit 7 stops, the clamp fixing cylinder 4 (second cylinder of FIG. 3) installed at the lower side is up, and the hole 29 is formed in the lower clamp arm 20 of the clamp unit 7. The cylinder rod is inserted to fix the clamp arms 18 and 20. In this state, when the chain 5 is retracted by the drive motor 10 in the reverse direction of the strip traveling direction, the upper clamp arm of the clamp unit 7 ( 18) is up.

At this time, when the clamp holder 30 is operated, the cam 15 of the upper clamp arm 18 moves to the upper sliding block 16 while moving along the shape of the upper sliding block 16, and at this time, the upper clamp arm 18 ) Is connected to the lower clamp arm 20 and the hinge 19 so that the upper clamp arm 18 is opened with the lower clamp arm 20 with the hinge 19 as the axis.

At this time, since the lower clamp arm 20 is connected to the lower holder plate 32 of the clamp holder 30 while sliding, the clamp holder 30 is not separated.

In this way, when the upper clamp arm 18 is opened, the strip S is removed and the clamp portion 7 is momentarily advanced to clamp the clamp portion 7 and when the clamp is completed, the lower clamp fixing cylinder 4 is down. Put it.

When the fixing cylinder 4 is completely down, the clamp portion 7 is moved to the standby position (see FIG. 3) by the drive motor 10 and the chain 5, where the movement of the chain 5 is finished. .

Upon completion of the work, the plate tables 23-1 and 23-2, which are down at the front and rear ends of the tension rolls 26, are lifted up by the pneumatic cylinders 24-1 and 24-2. All operations of the mail order device are terminated.

The above-described mailing device operating mechanism is shown in FIG. 8 as described above.

As described above, according to the present invention, because the mailing operation is made without the need for separate personnel, safety accidents due to the conventional manual work is prevented, and work such as tying strips with ropes is unnecessary, thereby improving workability and work efficiency. This has the effect of being improved.

In the above description, the technical idea of the strip plate sheet of the tension roll according to the present invention has been described together with the accompanying drawings, but this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
