Description

[Detailed Description of the Invention] Is this '/) issued' a flag attached to Kozen and closed after shipping? This invention relates to a device for preventing misalignment of carton sealer flags in the non-curling pasting method.

No. 9 = The installation of Kome no Kori Masaki' involves folding the glued flag with a guide rod and pressing it with a press roller.
A discrepancy occurs.

This discrepancy between the flaps is caused by the characteristics of the carton, the width of the guide, the height of the guide, the angle at which the flap is pushed into the press roller, the timing, and other factors.

Recently, quality requirements for misalignment have been increasing, and complaints have been raised when the misalignment of salmon exceeds 3 mm.In order to prevent misalignment of 3 mm or more, the width of the guide, the width of the feed bar, etc. We have tried this, but it is not stable at all, and the current situation is that several pallets of defective products are produced every day.

This invention has a unique configuration in order to solve the above technical problem.

A feed bar for transporting the cartons with a 200mm mark, a folding kite for folding in the flag, a finger for aligning the tips of the 7 lamps, a roll for temporary pressing, and a press roller for crimping the cartons. A carton sealer frang misalignment prevention device characterized by comprising:

Next, this invention will be explained in detail based on the drawings. A feed bar 1 for transporting a glued carton C on a roll a and a folding guide for folding in a flap d of a carton C. Finger 3 is used to align the tips of laps 2 and 7. By moving the finger 3 to the human position, the air valve 4 and the air valve 4v are operated to attach the tip to the tip of the cylinder 5. The roll 6 temporarily presses the flaps d with their tips aligned, the cam follower 7 that operates when the finger 3 moves to position B, and the cam follower 7 of the follower 7.
Push down the cyst flange block 8 and remove the lever 9 L % Finger 3 is lifted up, and the screw coil panel 10 is used to remove the finger 3 from the flag dJ, and the tension coil spring 1 is used to pull the finger 3 back to its original position.
7 of carton C further transported by feed bar 1 and feed bar 1.
When the press roller 12 and finger 3 for pressing the lug d are pulled back to their original positions on the spline shaft 13, the air valve 14 and the lever 9, which are made to pull up the roll 6, are returned to their original positions. A return block 15 is used for this purpose, and a linear motion bearing 16 is used for making the finger 3 have a stroke of several mm.

Further, to explain this invention in detail, first, the carton C with the glue M) conveyed on the roll a by the feed bar 1 is folded by 7 laps d by the folding guide 2, By abutting the finger 3 and pushing the finger 3 forward against the coil spring 11, the tips of the seven laps d are aligned.

Next, when the carton C is conveyed to position A by the feed bar 1 with the tips of the flaps d aligned with the fingers 3, the air valve 4 is activated and the cylinder 5 is actuated. The roll 6, which is attached to the carton C, is lowered onto the carton C, and temporary pressing is performed with the tips of the wraps 7 being aligned.

Furthermore, when the carton C is conveyed to position B by the feed bar 1, the cam follower 7 is activated to push the stopper block 8 away in the direction of arrow 061 in FIG.
is removed, the finger 3 is lifted up by the tension of the threaded spring 10, and when the finger 3 is removed from the flap d, it is pulled back by the tension of the tension coil spring 11.

On the other hand, carton C is connected to i by feed bar 1 and layered by press roller 12.

When the fin car 3 is pulled back on the spline shaft 13 by the tension coil spring 1 to its original position, the air valve 14 operates to pull up the roll 6, and the lever 9 is locked to the return block 15. As a result, the lever 9 is returned to its original position, the push of the stop block 8Q is released, and the tip of the lever 9 is hooked.
Finger 3 returns to its original position c/) and waits for the other carton C.

In addition, the height of the carton C is uneven by several mm, so the linear motion bearing 16 requires a stroke of several mm+ for the fin car 3, and the spline shaft 13 is raised several steps. It can absorb the height of roses.

The invention has the following unique effects due to the above configuration.

(a) After gauging the tip of the flap that was pressed in with the folding guide with a finger and temporarily pressing it with a roll, press it with a press roller and press it with a flan 7k Ji.
(ii) Temporary pressing was performed on the glued part in the flat state, so the misalignment of the flaps was stabilized and was within about 1 mm.
Since it has a stroke of several mm+, even if the carton height varies by several mm')), it can be absorbed.

(c) By raising the spline shirt a few steps, the variation in cylindrical shape can be absorbed by ε.
