It can be fixed and can be adjusted manually or automatically. The conveyance direction of the sheet 101 can be adjusted by changing the stop position of the locking members 6b and 6b, and the stop of the locking members 6b and 6b can be arbitrarily set by setting a drive motor (not shown) of the conveyance mechanism 6. The position can be changed.

  In the ultrasonic welder 7, one sheet piece 101a and the other sheet piece 101b folded in two at the folding side 102 are parallel to each other in the vicinity of at least one side 103 (see FIG. 4) perpendicular to the folding side 102. This is an ultrasonic welding apparatus that welds to the surface.

Specifically, the ultrasonic welder 7 is an ultrasonic welding apparatus that uses ultrasonic waves to weld a sheet-like thermoplastic resin, and is also called an ultrasonic welder.
That is, the ultrasonic welder is a processing means for instantly melting and bonding a thermoplastic resin by fine ultrasonic vibration and pressure.

  As shown in FIG. 2, the ultrasonic welder 7 is disposed so as to face the ultrasonic oscillator 9, the vibrator 10, an ultrasonic horn 11 (hereinafter simply referred to as “horn 11”) that is a resonator, and the horn 11. The receiving portion 12 supports the lower surface of the sheet 101, and an elevating mechanism 17 as an example of elevating means for elevating and lowering the horn 11.

  The ultrasonic welder 7 converts electrical energy into mechanical vibration energy, and simultaneously applies pressure by the pressing means, so that the joining surface of one sheet piece 101a and the other sheet piece 101b of the sheet to be folded in half is formed. , Generating strong frictional heat, and melting and bonding the resin.

Specifically, the ultrasonic welder 7 converts, for example, an electric signal of 50/60 Hz into electric energy of 20 kHz by the ultrasonic oscillator 9.
The electrical energy of 20 kHz amplified by the ultrasonic oscillator 9 is transmitted from the ultrasonic oscillator 9 to a vibrator (for example, a converter composed of a ceramic piezoelectric element or the like) 10 and converted into mechanical vibration energy by the vibrator 10. Is done.
This mechanical vibration energy is transmitted to the sheet 101 through the horn 11.

  The sheet pieces 101a and 101b that are overlapped with each other by the transmitted vibration energy are rubbed to generate strong frictional heat at the boundary surface, and the resin is melted by this frictional heat so that the sheet pieces 101a and 101b are brought together. Can be welded.

The horn 11 is a resonator formed of a metal material.

The width dimension of the receiving portion 12 is larger than the width dimension of the horn 11. However, the size of the receiving portion 12 with respect to the horn 11 may be appropriately set depending on conditions such as the receiving portion 12 having an uneven portion 12a.
When the horn 11 presses the edge of the folded sheet 101, the upper end of the receiving portion 12 is substantially flush with the conveying surface of the conveying belt 6a.
The receiving part 12 is provided with a receiving part raising / lowering mechanism 18 and can be moved up and down by the receiving part raising / lowering mechanism 18, and the receiving part 12 can be stopped at a predetermined position in the vertical direction.

In the present embodiment, the horn 11 and the receiving portion 12 are configured to be moved up and down by the lifting mechanism 17 and the receiving portion lifting mechanism 18. It is also possible to configure only the receiving part 12 so that it can be raised and lowered.
As for the oscillation method to the horn 11 by the ultrasonic oscillator 9, the folded sheet 101 is pressurized by driving the horn 11 downward, and the oscillation to the horn 11 is performed after the pressurization pressure becomes a constant value. Set to ON. Thereafter, the oscillation to the horn 11 is turned off after the elapse of a predetermined time set in advance, and the horn 11 is driven upward to release the pressure applied by the horn 11.
Further, the oscillation timing of the ultrasonic horn is not limited to the above description, and can be set as appropriate.

As shown in FIG. 3, the sheet pressing mechanism 13 is a plate-like member that presses at least two edge portions of the folded sheet 101 at the welding position of the sheet 101.
The sheet pressing mechanism 13 includes a front edge pressing mechanism 14 and a lower edge pressing mechanism 15.

When the sheet 101 is disposed at the welding position in a state in which the folded side 102 of the sheet 101 is disposed on the downstream side, the front edge pressing mechanism 14 causes the edge of the folded side 102 to be parallel to the folded side 102. Means for pressing along the direction.
The front edge pressing mechanism 14 includes a plate-shaped front edge pressing member 14a arranged along a direction orthogonal to the transport direction, and a lifting mechanism (not shown) that moves the front edge pressing member 14a up and down. Z).

As shown in FIG. 3A, the front edge pressing member 14a has a predetermined clearance C1 between the front edge pressing member 14a and the transport surface (upper surface) of the transport belt 6a at the raised position.
Here, the clearance C <b> 1 is configured to be larger than the thickness dimension of the folded sheet 101.

The lower edge pressing mechanism 15 is a means for pressing the edge of one side 103 when the sheet 101 is arranged at the welding position with the folded side 102 of the sheet 101 arranged on the downstream side.

The lower edge pressing member 15a has a predetermined clearance C2 and a conveying surface (upper surface) of the conveying belt 6a at the raised position.
Here, the clearance C2 is configured to be larger than the thickness dimension of the folded sheet 101.

  When the clear file 100 is manufactured by the clear file manufacturing apparatus 1 having the above-described configuration, it is performed according to the following operation procedure.

First, in FIG. 1, the sheet 101 is folded in half by the folding machine 3 with the folding side 102 as a boundary and supplied to the ultrasonic welder 4.
The supplied sheet 101 is transported in the transport direction by the transport mechanism 6 of the ultrasonic welder 4.

Next, as shown in FIG. 3A, the conveyed sheet 101 temporarily stops at the welding position.
At this time, both ends of the sheet 101 in the width direction of the sheet 101 are positioned by the guide members 8 and 8 (see FIG. 1), the upstream end of the sheet 101 is the locking member 6b, and the downstream of the sheet 101 The end is positioned by the pin members 16 and 16 coming out from below.

  Further, when the sheet 101 is conveyed to the welding position, the folding side 102 which is the downstream end of the sheet 101 is inserted into the clearances C <b> 2 and C <b> 1 in order, thereby suppressing swelling due to the folding of the sheet 101.

Next, as shown in FIG. 3B, the front edge pressing member 14 a of the front edge pressing mechanism 14 is lowered to press the edge of the folded side 102 of the sheet 101.
Thereby, the swelled state of the sheet 101 is suppressed and flattened.

Subsequently, as shown in FIG. 3C, the lower edge pressing member 15 a of the lower edge pressing mechanism 15 is lowered to press the edge of one side 103 of the sheet 101.
As a result, the sheet 101 is completely flattened.

  In the present embodiment, the sheet 101 is pressed in the order of the front edge pressing mechanism 14 and the lower edge pressing mechanism 15. In particular, the order may be changed back and forth, or may be executed simultaneously.

Next, as shown in FIG. 3D, the horn 11 is lowered by driving the lifting mechanism 17 (see FIG. 2) in a state where the sheet 101 is pressed by the sheet pressing mechanism 13.
Then, as shown in FIG. 3 (e), the edge of one side 103 of the sheet 101 is sandwiched between the horn 11 and the receiving part 12 on the outside of the lower edge pressing member 15 a, and the ultrasonic vibration is generated by the horn 11. To melt and weld.
In this way, the sheet pieces 101a and 101b are welded together to form a linear welded portion 104 (see FIG. 5) parallel to one side 103 on the sheet 101, and the clear file 100 is completed.

Thereafter, the horn 11, the front edge pressing member 14 a and the lower edge pressing member 15 a are raised, the pin members 16, 16 and the receiving part 12 are lowered, and the clear file 100 is transferred to the conveying part 5 by the conveying mechanism 6. Be transported.
However, when the pin members 16 and 16 are attached above the transport unit 5, the pin members are raised and retracted. Whether to attach the pin member to the lower side or the upper side may be appropriately determined depending on whether the installation space is given priority or the ease of adjustment of each pin member is given priority.

  Next, in FIG. 1, in the transport unit 5, the clear file 100 is transported from the upstream side to the downstream side, and is supplied to the clear file bag making and packaging machine 2 connected to the clear file manufacturing apparatus 1.

  The clear file bag making and packaging machine 2 can unwind the raw film wound in a roll shape, cut it into a predetermined shape, and produce a packaging bag 200 with a flap for accommodating the clear file 100.

Moreover, the clear file bag making and packaging machine 2 can continuously and individually wrap the clear files 100 supplied from the transport unit 5 of the clear file manufacturing apparatus 1 and provide a flap seal to the flap.
The clear file 100 packaged in the flap-wrapped packaging bag 200 is conveyed to the stacker 20 and stacked.

As described above, in the clear file manufacturing apparatus 1 according to the present embodiment, the horn 11 and the receiving portion 12 are welded by sandwiching the edge of the folded sheet 101 pressed by the sheet pressing mechanism 13.
As a result, the state in which the bi-folded sheet 101 swells in advance is flattened by the sheet pressing mechanism 13, so that the variation in folding can be reduced and poor welding can be suppressed.

  In addition, since the folded state of the folded sheet 101 can be suppressed by the sheet pressing mechanism 13, the distance (stroke) between the horn 11 and the sheet 101 can be reduced, and the clear file manufacturing cycle time can be shortened. Can do.

In addition, the clear file manufacturing apparatus 1 according to the present embodiment includes a lifting mechanism 17 that lifts and lowers the horn 11, and lifts and lowers the lifting mechanism 17 when the edge of the folded sheet 101 is welded (lowering in the present embodiment). Then, the folded sheet 101 is sandwiched between the horn 11 and the receiving portion 12.
Thereby, the sheet | seat 101 can be clamped reliably without deviation.

Moreover, in the clear file manufacturing apparatus 1 in this embodiment, the receiving part 12 has the uneven part 12a in the part facing the horn 11.
Moreover, when the uneven | corrugated | grooved part 12a is provided in the receiving part 12 like this embodiment, manufacturing cost can be suppressed rather than comprising an uneven | corrugated | grooved part on a curved surface like a rotation roller. Moreover, there is an advantage that the degree of freedom in designing the concavo-convex pattern can be increased if the concavo-convex part 12a is configured on a plane like the receiving part 12. Furthermore, when the thickness and material of the sheet 101 are changed, the uneven pattern may also be changed. When an uneven part is formed at the tip of the ultrasonic horn, it takes time to replace and adjust the ultrasonic horn. It takes time to work. On the other hand, when the concave and convex portion 12a is formed on the receiving portion 12, there is an advantage that the replacement work is shortened because the adjustment of the receiving portion 12 does not take time. When the ultrasonic horn is replaced, the adhesive strength varies easily due to individual differences of the ultrasonic horn, but when the receiving portion 12 is replaced, there is an advantage that the variation in the adhesive strength can be reduced. For the purpose of the ultrasonic horn, there are restrictions on the material to be processed. For this reason, for example, it may not be possible to select a material considering wear resistance. However, when the concave / convex portion 12a is formed in the receiving portion 12 as in the present embodiment, there is an advantage that the material selection is eliminated and a material considering workability and wear resistance can be selected.
As a result, the manufacturing cost can be reduced by forming the concavo-convex portion separately from the ultrasonic horn, rather than forming the concavo-convex portion on the ultrasonic horn as the ultrasonic welding means.

  The clear file manufacturing apparatus 1 having the above configuration is connected to the downstream side of the clear file manufacturing apparatus 1 and includes a clear file bag making and packaging machine 2 for packaging the clear file 100 manufactured by the clear file manufacturing apparatus 1. The clear file manufacturing system 50 that can be executed consistently from manufacturing to packaging of the clear file 100 can also be provided.

Since the cycle time can be shortened as described above, the clear file bag making and packaging machine 2 is installed downstream of the clear file manufacturing apparatus 1 without reducing the cycle time of the clear file clear file bag making and packaging machine 2. The clear file 100 can be packaged while being connected and continuously manufactured. As a result, the tact-up from the manufacturing to packaging of the clear file 100 can be achieved, and the production efficiency is improved.
Moreover, since the integrated production from the production of the clear file 100 to the packaging becomes possible, the production of a small lot becomes easy.

  A clear file manufacturing apparatus 1 that embodies the present invention and a clear file manufacturing system 50 including the clear file manufacturing apparatus 1 are useful techniques for manufacturing a clear file and individually packaging the manufactured clear file. .
