At the beginning of the operation, as shown in FIG. 3, the front end of the swing frame 20 is raised, and the lower bellows-folding clearing film 6a and the upper bellows-folding clearing film 6b are separated from each other vertically. The lower slide frame 12 and the left and right upper slide frames 23 are separated from each other, the bellows folding cleaning films 6a and 6b are extended, and the tie forming device 3 is lowered.
In preparation for bag mouth bundling, a tie winding reel is set in the bag mouth bundling device, and the leading end of the bundling tie B is placed in the tie feed roll 2, the tie guide member and the guide groove 29 of the tie forming device 3, and the holding piece 26 Thread horizontally to straddle.

First, after the power switch is turned on, the bag mouth of the bag A is inserted between the upper and lower bellows folding films 6a and 6b through the insertion port 37, and then the start switches 34 and 34a (FIG. 2) are pressed simultaneously.
Then, the first motor 7 operates, and the link mechanism 21 pushes up the rear end portion of the side frame 18 and the front end portion of the swing frame 20 descends as shown in FIG. As a result, the tie twist hook 5 is lowered, and the upper bellows folding film 6b is lowered and overlaps the lower bellows folding film 6a to sandwich the bag mouth of the bag A.
The start switches 34 and 34a are moved and fixed along the long holes 36 and 36a to a position where they do not interfere with the insertion and removal of the bag mouth in accordance with the size of the bag A.

Next, the second motor 8 is actuated to rotate the pinion 15, and as shown in FIG. 5, the first rack 13 and the second rack 14 that mesh with the pinion 15 are translated in a direction in which the overlapping length becomes longer. . As a result, the left and right lower slide frames 12 and the left and right upper slide frames 23 approach each other, and the upper and lower bellows folding film 6a, 6b are folded in the width direction and sandwiched between the bellows folding films 6a, 6b.

In this case, after the tie clogging is eliminated, the start switches 34 and 34a are pressed, the bag mouth bundling operation is performed to the end without inserting the bag mouth, and the electric bag mouth bundling device is returned to the initial state.

While the swing frame 20 is returned to the initial position, the light emitting portion 39a of the cut button 39 blinks at a short interval of about 0.2 seconds, and when the return of the swing frame 20 to the initial position is completed, the cut is performed. The light emitting portion 39a of the button 39 changes from blinking to lighting.
When the swing frame 20 is not normally returned, the light emitting portion 38a of the tie up button 38 blinks at a short interval of about 0.2 seconds. In this case, the power switch is turned on again to return the electric bag mouth binding device to the initial operation state.

In order to resume the bundling operation, the bundling tie B is passed through the guide groove 29 of the tie forming apparatus 3 returned to the lower limit position, and the cut button 39 in which the light emitting portion 39a is lit is pressed. Then, the 4th motor 10 act | operates, the tie shaping | molding apparatus 3 raises, and the cutter 35 cut | disconnects the binding tie B. FIG.
Therefore, since the tip of the binding tie B to be newly fed faces the tie forming device 3 and is disposed at an accurate position, the binding operation of the bag mouth can be resumed immediately after the tie clogging is eliminated.
In addition, the light emission state of the light emitting units 38a and 39a changes in this way, and the operator is informed of what operation should be performed next.
