Description

BAG MAKING AND INSERTING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag making and inserting device for forming a bag body of a desired size and inserting contents such as a piece of paper or a book into the bag.

Patent Document 1 discloses an article insertion means for inserting an article (article) into a bag. The article inserting means arranges bags and contents in equal pitches on two conveying lines, respectively, and the two conveying lines intermittently repeat the operation of conveying the bag and the contents corresponding to one pitch and stopping. To drive. The article is pushed into the bag by the pusher while the two conveying lines are stopped.

However, the size or aspect ratio of the contents varies, and the number (thickness) of the contents inserted into one bag is also not constant. For this reason, it is difficult to prepare an optimal bag in view of the form of the content, and therefore, there is a demand for unifying the production of the bag and the step of inserting the content into the bag.

In addition, Patent Literature 2 discloses a technique for supplying a rectangular paper. For example, A5 size paper may be listed on the conveying line as the contents. In this case, since the stroke on which the pusher operates is shorter than the arrangement of matching the long sides of the individual papers in the stacking direction of the papers in the stacking direction, the pusher pushes the paper into the bag. You can reduce the amount of time required for the loading to some extent.

However, in the former arrangement, as the pitch between papers becomes relatively long, the number of contents that can be conveyed per predetermined time decreases unless the conveyance speed of the conveying line for conveying the contents is set high. In addition, since the operation speed of the pusher is limited, simply increasing the conveyance speed does not increase the number of contents that can be inserted into the bag per predetermined time. For this reason, in order to insert a large number of contents, such as a catalog mailed as a direct mail, into a bag such as an envelope within a limited time, the production of the bag, the conveyance of the bag and the content, and the ability to insert the content into the bag are comprehensive. Should be improved.

In addition, since the film 18 folded in two is twisted 90 degrees immediately after being sent from the film supply means 2, the longitudinal direction of the film 18 which reached the bag making means 4 corresponds to a conveyance direction. The bag making insert 14 will be described in detail in the following examples.

Example 1

Since a well-known technique can be applied to the drive source, the guide means, the conveying means, or the paper feeding means applied in the present embodiment, the illustration or description thereof is omitted. For example, a servo motor, an air cylinder, or a hydraulic cylinder is applied as a drive source. As a guide means, a sliding pair made by engaging a letter with a guide rail is applied. As a conveying means, a rotary treatment formed by screwing a ball nut to a feed screw is applied.

As shown in FIGS. 3 and 4, the bag manufacturing means 4 includes a heat cutter 24, a cutter operating means 26, a backup roller 28, and a cutter driving means 30. The case of the bag manufacturing means 4 is provided with the movable frame 34 in the bottom surface of the fixed frame 31 via the guide means 32. As shown in FIG. The movable frame 34 slides freely in the conveying direction with respect to the fixed frame 31. The heat cutter 24 installs the blade bar 36 extended in the width direction of the film 18 between two press plates 38. The blade bar 36 is heated by the heater built in this. As the cutter operating means 26, a cam mechanism for raising and lowering the heat cutter 24 in a timely manner may be applied along the cam rotated by the servomotor.

The cutter driving means 30 is a conveying means which moves in the conveyance direction with the movable frame 34 as type, and reciprocates the movable frame 34 along the conveying direction. The fixed frame 31 bears a pair of outer rotary wheels 40 and 41, a pair of counter rotating wheels 42 and 43, and a pair of guide rotating wheels 44 and 45, respectively, shown in FIG. Doing. The movable frame 34 bears the backup roller 28, the pair of inner rotation wheels 46 and 47, and the pair of variable position rotation wheels 48 and 49, respectively. In the figure, the elements with dots are displaced in accordance with the movement of the movable frame 34. The pair of outer rotary wheels 40 and 41 rotate by the drive source, respectively. Accordingly, the inlet belt 50 travels between the outer rotary wheels 40 and the inner rotary wheels 46 in the conveying direction, and the withdrawal belt 52 moves from the inner rotary wheels 47 to the outer rotary wheels 41. Travel in the conveying direction.

FIG. 6 shows a cross section taken along line X1-X1 in FIG. FIG. 6 is a front view of FIG. 6 viewed in the direction of arrow X2. The reciprocating means 12 includes a case 58 in which a horizontal frame 56 is joined to an upper end of the arcuate frame 54, a movable support 60 supported to slide freely on the horizontal frame 56, and a movable support body. Drive means 61 for reciprocating 60 in the conveying direction is provided.

The movable support 60 engages the type | mold provided in the upper part with the slide rail 62 attached to the upper surface of the horizontal frame 56. As shown in FIG. The drive means 61 is a conveying means which screw-coupled the ball nut built into the movable support body 60 to the feed screw 64 received by the horizontal frame 56. When the servomotor connected to the feed screw 64 alternately repeats starting and reverse rotation, the movable support 60 reciprocates. Since the four insertion means 10 are connected to the movable support body 60 via the hanger 66, the four insertion means 10 reciprocate with the movable support body 60. As shown in FIG. The speed at which the inserting means 10 moves straight in the conveying direction corresponds to the conveying speed at which the conveying means 6 conveys the bag 16.

The individual insertion means 10 should just move the pusher 68 with respect to the bag 16. For example, the conveying means which connected the ball nut to the pusher 68 may be suspended below the movable support body 60 by the hanger 66, and the conveying screw of the conveying means may be rotated by a servomotor. In this case, when the servomotor is started or reversed, the pusher 68 moves forward from the position shown in FIG. 6 toward the bag 16 and, on the contrary, retreats from the bag 16 to the position shown. The arrow P indicates the direction in which the pusher 68 advances.

FIG. 8: is the perspective view which looked at the conveyance means 6, the movement means 8, and the inclination board 70 provided between them in the arrow S direction shown in FIG. The conveying means 6 is provided with conveyance belts 72 and 73 on which the part 161 left for pasting the bag 16, and the trunk | drum 162 are mounted, respectively. Ventilation holes 74 and 76 are formed in these suitable places, and the negative pressure which generate | occur | produces in inlet ports, such as an air blower, arises in the ventilation holes 74 and 76. FIG. The moving means 8 is a conveyor which drives the several moving belt 78 to a conveyance direction. The speed at which the moving means 8 moves the contents 20 is synchronized with the conveying speed at which the conveying means 6 conveys the bag 16. Although the convex part 79 which supports the content 20 may be formed in the moving belt 78, the form of the moving means 8 is not limited.

Next, the operation of the bag-making inserting device 14 will be described. The alphabetic characters preceded by the following sentences are indicative of the operation process. The figures refer to FIGS. 1 and 2 in addition to indicating among the sentences. Moreover, the servomotor already described operates based on the program written in the storage medium which can access the computer which controls these.

A: The paper feeding means 22 provided on the side of the moving means 8 sends the contents 20, which is rectangular paper, toward the moving means 8, in a posture in which the long sides thereof are aligned in the conveying direction. At this time, the insertion means 10 retracts the pusher 68 as shown in FIG. 6, and the reciprocating means 12 stops the movable support 60 at a limit capable of moving backward. In addition, when there are many kinds of contents 20, the several paper feeding means 22 sends these contents 20, respectively.

B: The film 18 is sent from the film supply means 2, and reaches the drawing belt 50 of the bag manufacturing means 4 shown in FIG. After the film 18 passes between the heat cutter 24 and the backup roller 28, the cutter operating means 26 lowers the heat cutter 24. Thereby, the blade bar 36 of the heat cutter 24 is pressed against the film 18. In the process of lowering the heat cutter 24, the cutter driving means 30 moves the heat cutter 24 and the backup roller 28 in a conveyance direction together with the movable frame 34. FIG.

In the process of said B, the speed which the movable frame 34 moves straight is set equal to the speed which the film 18 passes between the heat cutter 24 and the backup roller 28. As shown in FIG. In addition, when the blade bar 36 is pressed down on the film 18, the film 18 folded in two overlaps with each other by receiving the heat of the blade bar 36, and at the same time in the longitudinal direction of the film 18. The way is melted and divided by the heat of the blade bar 36. Thereby, the film 18 becomes the rectangular bag 16 which makes the side edge 80 the longitudinal direction (segmented part) of the longitudinal direction.

C: The cutter operating means 26 raises the heat cutter 24 so that the blade bar 36 of the heat cutter 24 is withdrawn from the film 18. Immediately after this, the cutter driving means 30 moves the heat cutter and the backup roller 28 backward in the conveying direction together with the movable frame 34. Further, after the subsequent film 18 passes between the heat cutter 24 and the backup roller 28, the bag making inserter 14 repeats the process of B to form a new bag 16. do.

In this way, the bag making insert 14 can perform melting and dividing of the film 18 by the bag making means 4 while continuously sending the film 18 from the film supply means 2. As compared with the case where the melting and gluing and dividing of the film 18 are performed when the film 18 is stopped, the number of manufactured articles per hour of the bag 16 can be increased. 9 shows the bag 16 formed in the step B. As shown in FIG. As for the bag 16, the folded part 82 at the time of folding the film 18 into two is the innermost end, and the opposite end becomes the opening part 84. As shown in FIG. The pasting portion 161 extending from the opening 84 is positioned at the folded portion 82 of the film 18 so that one piece of the film 18 that is folded in two is longer than this and the other piece that is folded. It is formed by biasing.

In addition, the width | variety of the bag 16 shown by the dimension line x is a blade bar at the process of said B from the time point which the cutter operating means 26 withdrew the blade bar 36 from the film 18 in the process of said C again. It is corresponded to the distance which the conveying means 6 conveyed the film 18, until 36 is pressed down to the film 18. FIG. Therefore, in order to make the width | variety of the bag 16 wide, what is necessary is just to set the range which the cutter drive means 30 reciprocates the movable frame 34 widely. On the contrary, if this range is set narrow, the width | variety of the bag 16 can be narrowed. For this reason, the bag manufacturing means 4 can change the dimension of the bag 16 easily.

D: The bag 16 formed by the process of said C is conveyed to the conveyance belts 72 and 73 of the conveying means 6 by the withdrawal belt 52 of the bag manufacturing means 4. Based on the negative pressure guided by these vent holes 74 and 76, the paste portion 161 and the trunk portion 162 of the bag 16 are respectively adsorbed to the conveyance belts 72 and 73. Since the conveyance belt 72 of the conveyance means 6 is arrange | positioned lower than the conveyance belt 73, the pasting part 161 of the bag 16 conveyed by the conveyance means 6 moves downward from the opening part 84. It deforms so that it may incline toward and passes below the inclination plate 70.

E: As shown in FIG. 2, at the time when four contents 20 oppose each other in front of the four insertion means 10, the reciprocating means 12 insert four with the movable support 60. FIG. The means 10 is moved straight. At the same time as this, the respective inserting means 10 advances the pusher 68 shown in FIG. 6 to the bag 16 so that the contents 20 are directed from the moving means 8 to the bag 16. It slides and the contents 20 are immersed in the opening 84 of the bag 16. Reference numeral 81 designates a member that guides the contents 20 to the opening portion 84.

F: Four insertion means 10 retreat each pusher 68, and each pusher 68 returns to the position shown in FIG. The reciprocating means 12 changes the movable support 60 to reverse movement. Thereafter, the bag manufacturing inserting device 14 can repeatedly perform the steps A and below.

As described above, the bag manufacturing inserting device 14 can continue the manufacturing and conveyance of the bag 16, and can continuously perform the step of inserting the contents 20 into the bag 16. In addition, when the operation of the inserting means 10 is speeded up in the steps of D and E and the time for inserting the contents 20 into the bag 16 is shortened, the reciprocating means 12 moves by the movable support 60. The cycle time for reciprocating) can be shortened. In addition, according to the bag manufacturing inserting device 14, since the four inserting means 10 can simultaneously insert the contents 20 into the four bags 16, they can be inserted into the bags 16 per predetermined time. The number of contents 20 can be doubled.

In addition, this invention can be implemented also in the form which added various improvement, correction, or a deformation | transformation based on the knowledge of a person skilled in the art in the range which does not deviate from the meaning, and may implement in the following form. Four or more insertion means 10 may be provided in the movable support body 60.

According to the present invention, since contents can be inserted into a bag at high speed and continuously without depending on the hand of a person, a large amount of envelopes can be produced at one time, for example, when mailing a product catalog by direct mail. This is a useful technique for quickly filling the contents of all envelopes.
