It is composed of.

In this embodiment, the cutter blade cutting means 1O and the pressure bonding fixing means 11 are arranged above the rotary mechanism to cut the thin film body cutter 2 with the push cutting blade 10A, and the thin film body produced by the blade cutting is The cutter 2 is cut into a blade cradle 10
In the lower part rotated by 180 @ in a state where it is adsorbed to the carton 3, the pedestal 10B becomes the pressure contact part 11A that moves up and down by the cylinder IIB to perform pressure contact and fixation to the carton 3. However, the present invention is not limited to this, and the present invention is not limited to this. The structure may be such that the thin film cutter 2 is press-cut directly above the adhesive applied part of the carton 3 inside, that is, directly above the attachment part of the thin film cutter 2, and is pressed into contact with the carton 3 as it is.
Alternatively, the structure may be such that a thin film cutter 2 whose blade has been cut in advance is pressure-bonded and fixed.

Hereinafter, the individual parts constituting the device 1 of the present invention will be explained in order.

First, the carton storage section 4 and the suction means 5 for taking out cartons 3 one by one from the carton storage section 4 will be explained with reference to FIGS. 2 and 3.

As shown in the figure (the carton storage section 4 has a plurality of cartons 3
・3...... are stacked and placed, and the second
As shown in the figure, there is a table lifter 41 that moves up and down according to the number of cartons 3, an upper limit sensor 42 that detects the position of the topmost carton 3, and a reduction amount when the cartons 3 are taken out by the suction means 4 and reduced. Intermediate sensor 4 that detects
3 and the lower position proximity switch 44 of the table lifter 41
and an air nozzle 45 for spraying air onto the side surfaces of the top layer and several cartons 3 immediately below it, as shown in FIG.

The suction means 5 includes a take-out arm 51 and a suction cup 52 disposed at the tip of the take-out arm 51. After suctioning the spot, the take-out arm 51 rises slightly upward and moves forward (to the right in FIG. 1), and sends it to the next step, the transfer means 6, which will be described later. When a predetermined number of cartons 3 (for example, about 10 to 20 cartons) are sent to the next process and the number of cartons in the carton storage section 4 decreases, the intermediate sensor 43 detects the amount of decrease and the table lifter 41 rises by the amount of decrease. In addition, the carton storage section 4
When all the cartons 3 inside are used up, the table lifter 41 is lowered, the lower position proximity switch 44 is turned on, and a plurality of cartons 3 are newly set.

Incidentally, since there is a substantially vacuum state between the plurality of stacked cartons 3, when the suction means 5 suctions and takes out the cartons 3, the topmost carton 3.

Several cartons 3 directly below the top layer carton 3 may be taken out at the same time in a state where they are stuck together, but the air nozzle 45 removes the side surfaces of the top layer and several cartons 3 directly below it. By blowing air onto the cartons 3, air is interposed between the cartons 3, and only one of the topmost cartons 3 can be reliably taken out by suction.

Furthermore, the shape of the air outlet of the air nozzle 45 is preferably a horizontal slit so that air can be easily sent between the cartons 3, and the position of the air blowing is preferably on the side of the part that is sucked by the suction cup 52. Furthermore, a spraying force of about 1 to 6 kg/Cm''G is sufficient.

Next, the transfer means 6 will be explained based on FIGS. 4(A) to 4(C).

The transfer means 6 is for sequentially transferring the cartons 3 taken out one by one from the carton storage section 4 by the suction means 5 to the conveyance means 8 for the cutter attachment process, as described above. 62. The carton 3 taken out by the above-mentioned suction means 5 is sent between the upper conveyor 61 and the lower conveyor 62, and is transferred to the conveying means 8 through both conveyors 61 and 62. At this time, as mentioned above, the carton 3 is fed between the two conveyors 61 and 62 from the folding portion of the side wall, with the right side portion in FIG. Carton 3 is pulled by both conveyors 61 and 62.
62, which tends to cause the problem of being fed diagonally. In order to prevent this problem, the entrance portion 61A of the upper conveyor 61 is raised and opened until the entire middle portion of the carton 3 is fed between the two conveyors 61 and 62 (Fig. 4(A) e). This can be prevented by lowering the entrance portion 61A of the upper conveyor 61 after the entire middle portion is completely fed between the two conveyors 61 and 62.

Further, this problem of diagonal feeding is likely to occur on the exit sides of both conveyors 61 and 62. That is, when the carton 3 passes through both conveyors 61 and 62 and is transferred to the next process, the position adjustment means 7 and the conveyance means 8, the rear end of the carton 3, which passes through both the conveyors 61 and 62 last, has a side wall similar to the front end. Since this is the folding margin of the section, only this section is pushed by both conveyors 61 and 62 in the end, which tends to cause the problem that the carton 3 is transferred obliquely to the next process. In order to prevent this problem, before the entire width of the carton 3 passes through the outlet between the two conveyors 61 and 62, the outlet section 62B of the lower conveyor 62 is lowered and opened (see FIG. 4). C) I see), can be prevented.

Next, based on Figure 5, the position it! Im means 7 and conveyance means 8
I will explain about it.

The carton 3 transferred by the transfer means 6 onto the path of the transfer means 8 is first adjusted in position by the position adjustment means 7 disposed within the transfer path of the transfer means 8, and then transferred to the transfer means 8.
Carton clamping arm 81 attached to the endless conveyor of
- While maintaining the position adjusted by 82, 83, and 84, it is clamped and fixed and transported. Therefore, the application of the adhesive on the path of the conveying means 8 and the attachment of the thin film cutter 2 can be performed accurately with extremely high precision.

Position tI of the position adjustment means 7! i! To explain in more detail the clamping and fixing of the il and the conveying means 8, the carton 3 transferred onto the path of the conveying means 8 is stopped by coming into contact with the front end molds 71 and 72 that have risen in a protruding state on the conveying path. Carton 3. The position in the transport direction is adjusted.

Next, the width correction claw 73 is moved minutely by an air cylinder, etc.
- 74 comes into contact with the carton 3 from the side, and the position is adjusted in the direction orthogonal to the transport direction. After the position adjustment in the conveyance direction and the direction orthogonal to the conveyance direction is completed, the carton clamping arms 81, 82, 83, and 84 hold the carton 3.
are clamped and fixed from above and below, and after clamping and fixing, the front end mold 71.
72 and the width correction claws 73 and 74 are retracted from the conveyance path,
The carton 3 is transported while maintaining its positionally adjusted state.

Next, the adhesive application means 9 will be explained based on FIG.

The adhesive application means 9 includes an adhesive application nozzle 91 disposed on a passing line of the adhesive coated surface of the carton 3 being transported, and an adhesive application nozzle 91 disposed toward the transport path of the carton 3 so that the carton 3 is coated with adhesive. It is composed of a detection sensor 92 that detects that the device has been conveyed to the means 9. A sensor 92 detects that the carton 3 has been conveyed to the adhesive application start position.
When detected, the adhesive application nozzle 91 starts applying the adhesive. At this time, it goes without saying that the carton 3 is being transported by the transport means 8, and since the adhesive application nozzle 91 is disposed on the passing line of the adhesive application surface of the carton 3, the adhesive is applied to the adhesive of the carton 3. It is applied in a line on the surface where the agent is applied. To stop the adhesive application, a sensor may be installed to detect when the rear end of the carton 3 has passed, and the adhesive application may be stopped based on the sensor's detection. In device 1, carton 3
Since the conveyance speed is constant regardless of whether it is intermittent conveyance or continuous conveyance, the coating time is calculated from the conveyance speed and the adhesive coating length of the carton 3, and the adhesive application nozzle 9i uses the timer to apply the adhesive. It is preferable that the coating time be configured to stop. When using timer control, it goes without saying that the coating time can be arbitrarily set or finely adjusted.
Further, the adhesive application nozzle 91 is configured to be adjustable in each direction of the X-Y-Z axes with respect to the carton 3.

The thin film cutter 2 is pressure-bonded and fixed to the carton 3 of the adhesive application length by a pressure-bond fixing means 11 in the next step. For the cutter blade cutting means 10 and pressure bonding means 11 for manufacturing the thin film cutter 2, in addition to the above, each structure described in the previously proposed technique can be applied.

A cutter-equipped carton 3 to which a thin film cutter 2 is pressure-bonded.
A is the carton clamping arm 81 of the conveyance means 8 at the time when the front end of the full width portion of the carton 3A is sent between the upper conveyor 121 and the lower conveyor 122 of the discharge conveyance means 12.
- 82, 83, and 84 are released, and it passes between the upper conveyor 121 and the lower conveyor 122, and is transferred from the path of the conveyance means 8 to the cutter-equipped carton storage section 13. The discharge transfer means 12 may have any structure as long as it has the same structure as the transfer means 6 and can simply transfer reliably from the transfer means 8 to the cutter-equipped carton storage section 13. By having the same configuration as the transfer means 6, the cutter-equipped cartons 3A can be stacked and stored in the cutter-equipped carton storage section 13 in an aligned state.

As described above, according to the mounting device 1 according to the present invention having the above configuration, the non-metallic thin film cutter 2 can be mounted to the carton 3 with high precision and easily.

Next, a second embodiment of the present invention will be described based on FIG. This second embodiment has substantially the same structure as the first embodiment, except that the cartons 3' stacked and stored in the carton storage section 4 are already coated with adhesive, and the adhesive application means is The difference is that an adhesive exhibiting means 14 is provided instead of 9. In the second embodiment, the adhesiveness exhibiting means 14 is adjusted depending on the type of adhesive applied to the carton 3'.
The configuration of is changed as appropriate. For example, if the adhesive exhibits adhesive properties by heating, such as a hot melt adhesive, the adhesive exhibiting means 14 will be a heating part, and if the adhesive exhibits adhesive properties by irradiation with ultraviolet rays, The adhesiveness exhibiting means 14 is an ultraviolet irradiation section, and the structure of the adhesiveness exhibiting means 14 may be changed as appropriate depending on the adhesive and the method of exhibiting adhesiveness of the adhesive.

Incidentally, the adhesive for the carton 3' may be covered with release paper or the like. In this case, a release paper peeling means may be provided in place of the adhesive exhibiting means 14, so that the thin film cutter can be removed. 2 pressure bonding is possible.

[Effects of the Invention] According to the present invention, when attaching a non-metallic thin film cutter to a carton, the position of the carton is adjusted by the position adjustment means, and then the carton is clamped by the conveyance means while maintaining the adjusted position. The structure is such that the thin film cutter is fixed and transported, the adhesive is applied or adhesive is applied on the transport path, and the thin film cutter is fixed by pressure, so the attachment of the thin film cutter to the carton is extremely high. , and has the advantage of being simple.

Further, according to the present invention, since the direction in which the thin film cutter is attached to the carton is opposite to the blade cutting direction when manufacturing the thin film cutter, the thin film cutter is made of a highly safe non-metallic thin film cutter. It also has the effect of being able to exhibit cutting performance equivalent to or better than conventional thin film cutters made of tin.
