2. Description of the Related Art Today, in order to quickly process a plurality of mail items, an encapsulating and enclosing device for enclosing and enclosing the same in an envelope has been proposed. Next, the enclosing and sealing device will be described with reference to FIGS. 7 and 9. In FIG. 7, 13 is an envelope gripper, and this envelope gripper 13 can contact the envelope 1 sent from the envelope passage 11 onto the table 12 to position the envelope 1. . Further, 10 is a flap holding roller, and this flap holding roller 10 can hold the flap 1a (envelope lid) of the envelope 1 which is positioned.

On the other hand, A is an envelope opening device for opening the envelope 1 set at a predetermined position by the envelope gripper 13 and the flap holding roller 10. The envelope opening device A includes a pair of insert guides 3 and 4 having a substantially V-shaped cross section, a standby position (shown by a dotted line) and an insertion position (shown by a solid line) shown in FIG. And a swing means 5 for rotating between the two.

The swinging means 5 includes a rotating body 8 for individually fixing and supporting the insert guides 3 and 4 which are rotatably provided around the shaft portion 7, and a pin P fixed to the rotating body 8. A slide plate 9 that engages with the pin P, and a spring S that constantly biases the slide plate 9 toward the envelope 1. The swinging means 5 is rotated by a drive source (not shown) that moves the slide plate 9 in the arrow direction against the spring S so as to separate the tip portions of the insert guides 3 and 4 from each other to the left and right. Then, both insert guides 3 and 4 can be inserted into the envelope 1. The envelope 1 into which the insert guides 3 and 4 have been inserted has a structure as shown in FIG.
The envelope opening corresponding to the formation height of 4 is opened.

Then, the insert carriage B for hooking one end of the enclosed article 2 moves toward the envelope 1 in the opened state, and the enclosed article 2 is enclosed in the envelope 1.
When the enclosed material 2 moves toward the envelope 1, the enclosed material 2 passes through the inside of the V-shaped insert guide having a V-shaped cross section.

On the other hand, when the enclosure of the enclosure 2 is completed,
The gripper 13 sandwiches the envelope 1 and the enclosed object 2 in the envelope 1 and moves toward the sealing device (not shown), and the envelope 1 is sealed by the sealing device. Since this sealing device is not the gist of the present invention, its detailed description is omitted.

[0007]

However, there are the following problems in the envelope opening device and the enclosed material enclosing method of the conventional enclosing and enclosing device described above. For envelopes used for mail,
In order to make it possible to confirm the address and the like printed on the enclosed matter from the outside of the envelope, there are many cases in which an opening is provided in the envelope as shown in FIG. 10 and a transparent film 6 is attached to the inside of the opening. By the way, in order to enclose the enclosed matter 2 in the envelope 1, if the enclosed matter 2 is moved in the envelope, the enclosed matter 2
Therefore, there is a problem that the transparent film 6 is caught and the enclosure 2 is broken and deformed.

Further, the enclosing and sealing device is operated at a high speed to enable swift processing of mail, and accordingly, the rotation speed of the insert guides 3 and 4 of the envelope opening device A is also high. It is set. Therefore, the insert guides 3 and 4 may not properly stop at the insertion position (rotation end position) shown in FIG. 8, that is, they may rotate more than necessary due to inertia. There was the inconvenience of cutting through 1.

On the other hand, since the insert guides 3 and 4 have a V-shaped cross section as shown in FIG. 11, the enclosure 2 cannot be inserted inside the corners of the insert guides 3 and 4 (enclosed). There is an inconvenience that a void H having a height lower than that of the article 2 is formed, and the width of the enclosed article 2 that can be enclosed in the envelope 1 is limited.

Further, as shown in FIG. 12, when the enclosed article 2 is moved and enclosed in the envelope 1 opened by the insert guides 3 and 4, the height of the enclosed article 2 is increased.
Even if the height is lower than the opening height of the enclosure 2, the insert guide whose opening height becomes lower as it is separated from the right and left may collide with the corners 2a, 2a at the upper left and right ends of the enclosure 2. Deformation, breakage, etc. occurred.

Embodiments of the present invention will be described with reference to the drawings. The same parts as those of the conventional example are designated by the same reference numerals, and the duplicate description will be omitted. FIG. 1 is a diagram showing an embodiment of an envelope opening device of an enclosing and sealing device according to claim 1 of the present invention. In FIG. 1A, reference numeral 1 denotes an envelope having a transparent film 6 inside the opening. The envelope 1 has a transparent film 6 on the left side of the envelope in the figure.

Reference numerals 3 and 4 denote insert guides which are substantially V-shaped in cross section and which are provided in a pair on the left and right sides. The insert guide 4 on the left side in the drawing contacts the transparent film 6 when inserted into the envelope 1 ( The lower surface in the figure) is formed so as to cover the transparent film 6. The insert guide 4 covers at least the envelope opening side of the transparent film. This insert guide 4
When the envelope 1 is inserted into the envelope 1 and the envelope 1 is opened, it covers the transparent film 6 as shown in FIG. It is possible to eliminate the contact between the transparent film 6 on the side and the enclosure 2, and it is possible to solve the inconvenience such as the deformation caused by the enclosure of the enclosure 2.

On the other hand, FIG. 2 is a view showing an embodiment of the envelope opening device of the enclosing and sealing device according to the second aspect of the present invention. In FIG. 2, reference numerals 3 and 4 denote insert guides which are formed in a pair of left and right and have a substantially V-shaped cross section, and the insert guide 4 on the left side in the figure has a large size so as to cover the transparent film 6 attached to the envelope 1. I am doing it. The turning path 4a of the insert guide 4 is formed to extend to the turning path 3a of the other insert guide 3.

By the way, both insert guides 3 and 4
If the insert guides 3 and 4 are simultaneously rotated, the two insert guides 3 and 4 come into contact with each other during the rotation. Therefore, the insert guide 3 is first rotated as shown in FIG. As described above, the insert guide 4 having a large shape is rotated. As a result, the two insert guides do not come into contact with each other, so that the insert guide can be formed into a desired shape, and even the transparent film 6 having a large shape can be properly covered.

On the other hand, FIG. 3 is a view showing an embodiment of the envelope opening device of the enclosing and sealing device according to the third aspect of the present invention. In FIG. 3, reference numerals 3 and 4 denote insert guides provided in a pair on the left and right, and the swing device 5 and the drive source for rotating the insert guides 3 and 4 are provided with a speed control device such as a speed controller (not shown). (Shown) is installed. With this speed control device, the rotation speed of both insert guides 3 and 4 is fast from the standby position to a predetermined angle (45 degrees in this embodiment) shown by the dotted line Z in the drawing, and the insertion guide is inserted from this predetermined position Z. It is set to decelerate up to the position (stop position).

According to the envelope opening device having the above-described structure and operation, the decelerated insert guides 3 and 4 can be properly stopped at the insertion position (stop position).
Inconveniences such as tearing the envelope 1 can be solved.
Since both insert guides 3 and 4 rotate quickly up to the predetermined angle Z, the throughput of the envelope opening device is not reduced.

On the other hand, FIG. 4 is a view showing an embodiment of the envelope opening device of the enclosing and sealing device according to the fourth aspect of the present invention. FIG. 4 is a cross-sectional view showing the insert guide (only the left side is shown). This insert guide has a first inclined portion X and a second inclined portion Y connected to the first inclined portion X, and the first inclined portion is formed. The inclination of X is set to a substantially right angle, and the second inclined portion Y
Is set to be smaller than that of the first inclined portion X.

The insert guide having the above-mentioned shape secures an opening height in which the enclosed article 2 can be inserted up to the vicinity of the side portion of the envelope 1 as compared with the conventional insert guide (see FIG. 11). Since the lateral width of the void H formed inside can be reduced, it becomes possible to enclose the wide enclosed article 2 in the envelope 1.

Next, with reference to the flow chart shown in FIG. 5 and FIG. 6, a method of enclosing the enclosed material of the enclosing and enclosing apparatus according to claim 5 of the present invention will be described. First, the envelope gripper 1 described above
The envelope 1 is set at a predetermined position (see FIG. 7) by 3 and the flap holding roller 10. (Step 1)

Next, the insert carriage B is moved to insert the tip of the enclosed article 2 into the insert guides 3 and 4 at the standby position. (Step 2) In this step 2, the enclosed article 2 moves to the insert guides 3 and 4 having a substantially V-shaped cross section that widens in the direction of the enclosed article 2 as shown in FIG. The tip is properly inserted without causing the above.

Next, the insert guides 3 and 4 in which the tip of the enclosed product 2 is inserted are rotated, and the insert guides 3 and 4 are inserted into the envelope 1 to open the envelope 1. (Step 3) (see FIG. 6B)

Then, the insert carriage B is moved again so that the enclosure 2 is enclosed in the envelope 1. (Step 4) In this Step 4, since the tip of the enclosed product 2 is already inserted into the insert guides 3 and 4, it is possible that the enclosed product 2 and the insert guides 3 and 4 collide with each other. Without being deformed, the enclosure 2 is guided by the insert guides 3 and 4 without being deformed, and is properly enclosed in the envelope 1.

[0028]

As described above, the envelope opening device of the enclosing-sealing device and the method for enclosing the enclosed material according to the present invention are inserted into the envelope by pivoting so that the leading end portions thereof are opened left and right respectively. In an envelope opening device of an enclosing and sealing device having a pair of insert guides having a substantially V-shaped cross section that opens the opening of the envelope, the insert guide is formed so as to cover a transparent film attached to the inside of the envelope. Therefore, it is possible to eliminate the contact between the enclosed material and the transparent film and solve the breakage, deformation, etc. of the enclosed material.

Further, the pair of insert guides are formed in such a size that the rotation path of one insert guide and the rotation path of the other insert guide intersect each other, and the pair of insert guides are rotated separately. Since it is configured to perform the operation, it is possible to prevent the pair of insert guides from contacting each other, and it is possible to form the insert guide into a desired shape.

Further, speed control means for controlling the rotation speed of the insert guide is provided so that the rotation speed of the insert guide is fast from the standby state to a predetermined angle and is decelerated from the predetermined angle to the rotation end position. Therefore, the insert guide can be appropriately stopped in the envelope, and the tearing of the envelope by the insert guide can be prevented.

Further, since the corner portion of the insert guide is formed by the first inclined portion and the second inclined portion connected to the first inclined portion, the inclination of the second inclined portion is set to be smaller than the inclination of the first inclined portion. ,
The height of the opening into which the enclosed item can be inserted can be ensured up to the vicinity of the side portion of the envelope, and a wide enclosed item can be enclosed in the envelope.

In addition, as a method of enclosing the enclosed material, first, the tip of the enclosed material is inserted into the insert guide in the standby state, and then the insert guide in which the tip of the enclosed material is inserted is rotated to open the envelope, Next, the insert guide guides the insert to enclose the enclosed material in the envelope that has been opened by the insert guide, so it is possible to prevent a collision between the enclosed material and the insert guide, and the left and right end portions of the enclosed material. It is possible to eliminate the deformation.
