It is attached at an appropriate position below the correction rod 65, which moves up and down together with the correction rod 65. This corrector 65 has its upper end facing the middle of the sill roller 3-, and is movable up and down in a vertical state. A spring 66 is arranged between the upper end protrusions of 65, and this correction tithe 6! Force S upward. Note that a one-way clutch and an electromagnetic brake are provided on the shaft of the swinging rod 57 (
Only when the electromagnetic brake (not shown) is in operation, the one-way clutch is released, forming a reversal prevention mechanism that allows the swinging rod 57 to rotate only in the clockwise direction in FIG.

Reference numeral 68 denotes a brake, which allows the swinging rod 57 to move slowly even when the reno-51 rises rapidly, so that the diameter of the object to be packed can be accurately detected.

Next, the operating state of the present invention will be explained.

Now, the packaging machine main body 10 is at the highest position, and the end faces of the Nonan P-way 14 in the main body 10 are connected to the curved left and right fixed arches 2.3 fixed to the machine frame 1 ( Figure 4)
. In addition, the left and right slide P arches 20 and 21 are opened to the maximum extent and are completely housed in the case 25, and the lifter 30
is at the position shown by the dashed line in FIG. 9, that is, the intermediate stop position, and the swinging rod 51 is at the position shown by the chain double dot line in the figure.

When the power is turned on in this state, the diameter is detected and the electromagnetic brake installed on the axis of the swinging rod 57 that interlocks with A51 is activated, and the one-way clutch is activated, allowing the swinging rod 57 to rotate in only one direction. .

Due to the size of the object to be packed, the shorter the axis of the object to be packed, the more the correction rod 65Fi is pushed down. Therefore, touch safe t-@O is also lowered to 81. The swinging rod 57 maintains its moving position (i1) when the leno-51 is pushed up by the object to be packed by the brake, lE electromagnetic brake, and one-way clutch provided on the shaft of the swinging rod 57. Next, when the start button t-ON is turned on, the lifter 30 is raised by the rotation of the motor 82, and when the contact piece 64 of the touch sensor 60 provided on the corrector 65 comes into contact with the short levers 59 of the swinging rod 51. , This signal causes the motor 320 to stop rotating, the lifter 30 to stop rising, and #
Fixed in position. In response to the signal from the touch sensor 60, the motors 28.21 of the slide arches begin to rotate, allowing the left and right slide arches 20.21 to pass through the bottom of the packing machine main body 10 below the center shaft. The object to be packed moves forward into the core hole WO, and the central origin provided with the guy P rod 2rK of the arch 20.21 slides into the case 25 and the switch L

, the phototube provided on the bottom surface of the main body detects the object to be packed Wt- and stops at the 9 position. Further, the reversal is completed after a predetermined period of time 41 kHz has elapsed due to TIO T2, but before that, the secondary tightening mechanism starts secondary tightening of the knots in response to the signal from the phototube. Therefore, the nocend protrudes from each arch and the nocendway, and is wound around and tied tightly around the object to be packed. The secondary tightening of 79nP started when the phototube was turned on,
When the timer T3 completes the rotation, the camshaft is rotated again by the control motor, the non-nend supply end side is gripped and fixed, and the non-nand is held in a bound state. At the same time as the cam shaft stops rotating, the timer T4 is turned on and the non-nend supply end side is gripped and fixed. After the lapse of time, the camshaft rotates again to complete the bonding and cutting process between the overlapping parts and the -times of packaging.Next, the rotation of the camshaft is stopped by turning on the other limit switch L84. In order to do this, the first body 10 is raised by the cylinder 8, and the number P way 14 in the fifth body 10 is at a certain position.

When it connects with the upper edge of the fixed arch 2.3 and reaches the 9th position, the limit switch L85 is turned on and the upward movement of the main body 10 is stopped. Motor 39 of lifter roller 3 at the same time as stopping
The timer T5 connected to the roller 3 is turned on, and the roller s6 rotates for a predetermined period of time, that is, when the diameter of the object to be packed is detected, the shaft of the roller rotation adjusting means connected to the motor 39 of the roller 3 is rotated by the swinging rod 51. Due to the motion, it rotates within a pre-adjusted rotation for one hour and then stops. In other words, the items to be packaged are
$j or 1/4 turn. At the same time, the knot feeding mechanism feeds the knot into each arch for a predetermined period of time.

After that, from lowering the main body to gluing and cutting the overlapping part 1
The operation is the same as described above until the lifting of the second main body and the rotation of the lifter roller, and when three or four knots are applied to the object to be packed and the main body is raised, the highest position of the main body is detected. 17. Both slide arches 20 and 21 are opened by motors 211 and 28 in response to a signal from switch L85. When the slide arch 20.21 is completely retracted into the case 25.25, the slide arch! 0

Timer T6 that continues for 2KiI is ON.

The motors 3 and 2 rotate, and the roller 1- is delivered to the lowest position (dotted chain line in Figure 7). Therefore, the items to be packed are transferred onto the carry-out line OL by the carry-out board 41. When the lifter 30 reaches the lowest position, the limit switch L87 provided in the core part is turned on, stopping the lowering of the lifter 30 and canceling the electromagnetic play provided in the swinging rod 57 of the centering mechanism. . Therefore, the swinging rod 57 returns to its old position.

Also, the motor 3 of the lid 30! Due to the time-up of the timer T6 connected to the lifter, the lifter rises again and returns to the position shown by the solid line in FIG. At this time, the switch L88 is turned ON and the electromagnetic brake of the centering mechanism is turned ON in preparation for the next packing.

As described in detail above, the present invention has an extremely compact structure, detects the diameter of the object to be packed, and straps the object several times, and it has a great effect that packaging can be done in a short time and automatically. It is something that you have.
