Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an envelope holding device in an automatic sealing device that folds the tongue of an envelope and simultaneously seals the envelope using adhesive tape.

Regarding the automatic sealing device of the above type, the present applicant has previously filed an application for utility model registration (Utility Model Application No. 53-63756 - Publication of Utility Model No. 58-11599).

This automatic sealing device will first be explained with reference to Figs. 1 to 4. Fig. 1 is an overall view of its main parts, in which one plate is drawn from one end into A, B, C, and D by parallel lines. Section it out, make all the borders of each section a mountain fold, overlap the A side on the 0 side with a slight gap X, and make the outer edge of the A side a straight line and the folded part of the 0 side and the D side. The base body 2 is formed by placing the base body 2 close to each other to form a triangular shape as a whole, and bending the lower part of the rear end (left end) of the 0 side to the extent that it is almost parallel to the A side, and attaching an adhesive tape to the rear part of the base body 2. The automatic sealing device 1 is provided with three supporting rolls 4, an adhesion roller 5 for the tape, and a tape cutting blade 6.

To use this sealing device 1, first attach the adhesive tape 3 to the reel 4, then rewind one end of the tape so that the adhesive side faces forward (left side in the figure) and wind it in front of the application roller 5. Turn it, pass one end through the cutting blade 6, and temporarily adhere it to the rear end of side D.

Next, turn the envelope 7 in which the document is enclosed face down, and insert A from the front of the sealer 1 so that the folded tongue line 8 is along the outer edge 9 of the A side as shown in FIG.

Insert into gap X on side D.

Then, when the envelope 7 is held down by hand and the sealer 1 is moved to the left, the tongue piece is first pulled up at the front end of the 0 side, and the tongue piece is folded back onto the A side along the curved surface of the folded part of the 0 side. It is being fed.

Furthermore, when the sealing tool 1 is moved to the left, the right end of the tongue piece becomes 0.
It is completely folded back by 180 degrees at the rear end of the surface, and at the point where surface A ends, it overlaps with the place where the tongue piece of the envelope 7 that has passed through the gap (Fig. 3)

Since the adhesive tape 3 is wound around the attachment roller 5 with the adhesive side facing outward, the right end of the envelope 7 comes into contact with the adhesive tape 3 at the same time as the envelope 7 is bitten by the roller 5, causing the envelope 7 to move. At the same time, the tape 3 is pulled out from the reel and sequentially pressed by the attachment roller 5, and the folded tongue piece is sealed in that state (FIG. 4).

When the sealing tool 1 passes the envelope 7, the sealing is completed, but since the adhesive tape 3 is continuous, the lever is pressed and the cutting blade 6 cuts the tape 3.

When the sawtooth of the cutting blade 6 enters the unevenness at the rear end of the D side, the cut adhesive tape 3 adheres to this part, and even if the cut side is removed, the reel side remains in the state shown in FIG. Do not unnecessarily glue it to other parts.

Further, in the next operation, the envelope that enters the lower part of the attachment roller 5 can be adhered smoothly, and the movement of the envelope will not be hindered.

This completes one sealing operation.

This device has the advantage of being smaller and easier to use than conventional sealing devices, but requires the envelope to be held by hand.

And it has the disadvantage that it must hold the envelope securely from beginning to end of the sealing operation, which is relatively difficult.

The present invention attempts to overcome these disadvantages and aims to provide an envelope holding device that automatically holds the envelope fixed on a workbench when the sealing device is moved.

Next, an embodiment of the present invention will be described with reference to FIGS. 5 to 7.

Reference numeral 10 denotes a workbench on which the sealing device 1 described above moves from left to right to perform a sealing operation.

A guide lever 11 is provided on the side surface of the workbench 10.

The guide lever 11 is protected from an inclined part 12 descending downward from the left end toward the right and a horizontal part 13 following this, and is pivoted to the workbench 10 by a pivot pin 14 at the left end.

At the right end of the workbench 10, an envelope presser 16 with a presser piece 15 that presses the envelope on the workbench that protrudes onto the workbench is attached to a pin 17'.
A roller 17, which engages with the upper right end of the guide lever 11, is pivotally attached to the right end of the envelope holding portion 16.

Therefore, the guide lever 11 is biased in the clockwise direction by its own weight and is at the position shown by the dotted line, and the envelope holding part 16 is also at the dotted line position due to the weight of the roller 17 and the like, and the holding piece 15 is It is in a state of floating above the platform 10 (FIG. 6).

A traveling guide device 20 including rollers 1B, 18', etc. is provided below the workbench 10, and is guided by a rail 19 under the workbench to move left and right.

The guide device 20 is further provided with a roller 21 attached to the lower surface of the guide lever, and when the device 20 moves to the right, the roller 21 rotates the guide lever 11 counterclockwise, causing the guide lever 11 to move along the solid line. Rotate to the state.

Since the right end of the envelope pressing section 16 faces the right end of the guide lever 11 via the roller 17, the guide lever 11
By this counterclockwise rotation, the envelope holding part 16 is rotated against the pivot 17.
’ in a counterclockwise direction to press the envelope on the workbench.

The guide device 20 also includes a projecting piece 22 that extends to the edge (front edge) of the workbench 10 and bends upward.

The sealing device 1 used in this device has the same configuration as that shown in FIGS. 1 to 4, but is provided with a skirt 23 having a U-shaped cross section hanging down and connected to the protrusion 22 of the guide device 20. .

That is, when the sealing device is used, this skirt 23 is engaged with the protruding piece 22, and when the sealing device 1 is moved on the workbench 10, the guide device 20 is also moved in the same way. ing.

Due to this movement, the envelope holding unit 16 of the sealing device 1 is rotated via the guide lever to press down the envelope on the workbench, so there is no need to press the envelope by hand during the sealing operation, and the envelope can be held in a predetermined position. It will be held in this position until the sealing operation is completed.

Note that when the sealing device 1 is moved to the left and returned to the position shown by the dotted line in FIG. 7 after sealing one envelope, the guide lever 1 must be moved.
1. It is clear that the envelope holding portions 16 return to the positions indicated by the dotted lines and return to their initial states.

As described above, according to the device of the present invention, the envelope holding section can automatically rotate and press the envelope onto the workbench as the sealing device operates, so that the automatic sealing operation by the sealing device can be performed accurately. Moreover, it can be carried out efficiently, and the practical effects of the present invention are remarkable.
