Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lunar tube, and more specifically, to a novel configuration, it is possible to carry out practical work using a combination tube. j
17ru 13j (related to the ring)

To save labor on administrative processing 1. Currently, various types of monthly seal la are commercialized and put into practical use. However, compared to the conventional envelope sealing machine (Ritsu-C), due to the structure of the folding mechanism that creates folds in the 11-fold flap and folds it back to the main body side of the envelope to seal it, They had common or unique problems as described below.The configuration and problems are listed as follows.

a) Conventionally known configuration 1 The folding mechanism moves vertically JJ along the linear conveyance path of the envelope.
i [fl (iJ (includes a no roller, a reversing spiral guide plate, and an upper and lower pressure roller. One of the above folds (=I ke 1''-ra) has a narrow groove 11iii along the rotation direction, and the other roller has a narrow groove 11iii) It is shaped like a ball with ridge lines corresponding to the shape of the ball.

The date and month flaps are folded by the cooperation of the grooves and ridges of the above-mentioned creases [J-R], and then folded back by the reversing spiral guide plate until they touch the envelope body, and then The envelope body is crimped by a crimping roller.

b) Conventionally known configuration No. 2 As described in Japanese Patent Publication No. 49-38197, the folding mechanism is
1] In the linear conveyance path of the tube? It includes a folding device, a reversing spiral guide plate, and a heating and pressing roller. The flap of the envelope is folded by the cooperation of the blade plate and the slit, and is then folded back until it comes into contact with the envelope body by the reversing spiral guide plate, followed by -C heating and pressing roller. is crimped to the envelope body.

- Problems with conventionally known configurations 1 and 2 described above Configuration 1
At (yo, t'li?I)! The folds made with Ek are surprisingly straight ;) The sealing condition is poor, and in many cases the flaps are not folded in the Jji IIA way.

By passing through the above configurations 1 and 2, ``1 line work is l1iii
Since this is carried out using a series of members arranged linearly along the conveying path, 1) the conveyance distance of the cylinder becomes long;
Somehow the machine has become larger, but the sealed envelopes are ejected on the opposite side of the machine, making it difficult to operate on the 1'Z.

Common to configurations 1 and 2 above, when the flaps of the envelope are successively crimped from one end to the other, the flaps are often bent and sealed, especially when the contents of the envelope are thick. This is because when the flap starts to be crimped from the leading end, the trailing end is not yet in close contact with the envelope body, so the flap gradually shifts toward the trailing end due to the load applied sequentially from one side.
This is because it is crimped in a twisted state.

C) Conventionally known configuration No. 3 As described in Japanese Patent Publication No. 52-26198, a folding machine 4i'
j is a blade plate which is moved up and down by a solenoid disposed at the upper part, and a corresponding lower sleeve J] and a heating/pressing roller disposed below the slit. The flap of the IJ cylinder is formed with a J-fold in cooperation with the blade plate and the slit 1~, and the slit 1~ is further formed below the flap to reach the above-mentioned roller.
After being pushed in and folded back, and the 14 cylinder main body is pressed against the roller, the 1''-ra rotates in the opposite direction, and the month and day of the month and day on the purchase board are returned again. .

Conventionally known configuration No. 3 Problem J1π This configuration is applicable only when the envelope has a heat-fusible adhesive in advance, and when sealing the C envelope using general glue. The glue may stick to the blade, causing an inconvenience.Also, 1) Apply heat-adhesive adhesive to the tube in advance.
63 < means that the unit price of the envelope will be higher. Furthermore, the folding mechanism has a complicated structure because it requires a mechanism for vertically moving the blade plate and a mechanism for stopping and reversing the pressure roller.

d) As described in the conventionally known IR Sei-no-4, 1972-20097, the folding mechanism provided in the linear envelope conveyance path has a vertically movable actuating plate ( A blade plate) and a corresponding lower recess fM are provided adjacent to and synchronously with the actuating plate. When the envelope comes in, the tip of the flap presses the switch from limit 1 to T 7i 'c stop of the operating plate + l:
do. 11 flaps (recessed on the above operating plate) 1
The envelope is pushed shallowly into the envelope 11 to form a fold 11, the envelope 114 is coated with glue 71i, and then folded back and crimped against the envelope body using a separate member, and the envelope is discharged out of the feeding path on the opposite side to the insertion. .

Problems with the conventionally known 4115 construction No. 4: In this construction, the envelopes are conveyed along a straight path, so, like the problems with the known constructions No. 1 and 2, the machine becomes larger and the operability becomes difficult. It's bad. In addition, the limit 1 to 1111 L envelopes are stopped at the tip of the flap by the H type, which is thin and stiff like the H-I-Lon paper month.
In simple cases, it becomes impossible to implement. On the other hand, accurately stopping the envelope at a predetermined position where the blade is aligned with the parts other than the limit switch is a very costly and complicated process, considering that there are various envelope standards. becomes.

The present invention solves the problems of the prior art as described above.
The purpose is to provide a new and compact envelope sealing machine that can solve these problems. In addition, 13 is a conveyor machine for L to have 4 j cylinders in the first conveyance passage with glue A4[] machine ii6 biA (G1 and JJ cylinders are installed in the first conveyance passage). a hinge that emits a serration signal that aligns the envelope in a predetermined position; and a hinge that is actuated by the signal to move the envelope to a second conveyance path perpendicular to the first conveyance path, and creases the flap during the movement. A folding mechanism that performs sealing by forming and folding -C;
The device is characterized in that it has a 1]-shaped conveyance path that is curved at right angles on approximately the same plane.

The present invention will now be described in detail in accordance with preferred embodiments shown in the accompanying drawings.

On the right side in Figure 1), a guide plate 36 having a guide wall 36a extending from the casing 101 along the conveyance path is movable left and right in the figure. An upright wall 37 is installed at the end of the guide plate 3G.

The conveyor belts 1 to 34 are not parallel to the guide wall 36a, but are tilted slightly toward the guide wall 36a in the conveyance direction. The angle between the axis of the driven roller 32, 33 and the guide wall 3Ga is slightly deviated from a right angle.On the other hand, the axis of the transfer roller 31 is at a right angle to the guide wall 36a. Therefore, during conveyance, due to the above-mentioned oblique movement of the conveyance bell 1-34, the conveyance is carried out while being constantly applied with a force such that the bottom part thereof is pushed against the guide wall 3 (ia). At this time, after the envelope has passed through the embedding roller 31, it will be pushed (J4) against the respective pels I and 34 only by the above-mentioned two spheres 35, but both spheres 35 will be pressed against the respective pels I and 34 during the month. 1. Since the contact area is small and the ball f4 itself is rotatable in all directions, even if the insects on the temporary stand A are relatively large, there is no restriction on the traveling direction of the tube within the transport plane. The horns are small.

Therefore, even if the envelope is delivered crooked, the bell 1-
The direction and position are automatically corrected with the aid of the diagonal conveyance force of the Ti 34 and the rotatability in all directions of the Ti 36a in the system and its sphere 35, and eventually the guide wall 3Ga and This will ensure that the corner with the upright wall 31 is aligned.

The envelope is pushed into the above-mentioned predetermined position C', and is conveyed to the predetermined position. Therefore, the rotational force of C is avoided to move to the second conveyance path S in the direction perpendicular to the first conveyance path. As the rotor 41 rotates, the moon-shaped protrusion 42 digs deeper into the fold line portion, forming a crease there and causing the flap to stand up in the Ih return direction. (
