DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an FTP sheet reversing device in an FTP sheet transfer line.

FTP, or press-through backing (Press-1
Hrough Packing is generally made by continuously heating a thermoplastic film and molding it using vacuum or compressed air, filling the molded pocket with tablets, capsules, etc., and then hot-bonding the top with a metal sheet such as aluminum foil. This refers to a packaging format in which the product is trimmed to the desired size.

Further, the FTP sheet refers to both a continuous sheet obtained by the PTP method and individual trimmed sheet pieces, and the FTP sheet in the present invention refers to the latter individual sheet pieces.

In the PTP method, as described in Japanese Patent Application No. 154,125/1983 (Japanese Patent Application No. 80621/1989), which was invented by the present inventor, continuous sheets are trimmed into individual sheets, Continuously transported by a conveyor at appropriate intervals, one sheet is reversed and combined with the other sheet face-to-face, and multiple sheets of the combined pair are further stacked to form a line, and then wrapped with plastic film, etc. Automated packaging and product packaging equipment is being implemented.

The present invention further simplifies the invention related to the above application, and provides FTP
It is designed to smoothly and reliably invert and combine sheets.

The present invention will be explained below with reference to the drawings.

Fig. 1 is a plan view of the apparatus according to the present invention, and Fig. 2 is its A-
It is an A sectional view.

In both figures, reference numerals 1 and 1 indicate a pair of discs arranged at a predetermined interval, and both discs are driven by a gear 2 by a drive source (not shown).
, 2, rotates 90 degrees in the direction of the arrow, stops for a certain period of time, rotates 90 degrees in the direction of the arrow, and stops again.

Note that since both discs 1, 1 have the same structure, one of the discs will be explained below.

Reference numerals 3 and 4 designate platforms that are symmetrically provided on the front side of the disk 1 (the opposing surfaces of both disks) at a predetermined distance from the center of the disk 1.

Reference numerals 5 and 6 denote rockers provided on the back side of the disc 1, which are fixed to shafts 7 and 8 rotatably attached to the disc 1, and springs 9,
10 constantly applies a clockwise rotation force.

Reference numerals 11 and 12 denote presser plates fixed to the shafts 7 and 8 on the front side of the disc 1, and are configured to move together with the oscillators 5 and 6.

21 and 22 are guide plates arranged slightly below the center between both discs 1 and 1 with a passage 23 in between; 24 and 25 are discs 1 and 25;
The upper guide plate 5 is placed on the right side of the guide plate 21 and 22 at a predetermined distance from each other.

Reference numerals 31 and 33 denote attachments having rollers 32 and 34 on the lower side, which are configured as an FTP sheet feeding piece and a PTP sheet pushing piece, respectively.

Its upper part projects upwardly from the passage 23 between the guide plates.

The rollers 32, 34 of this attachment are connected to the guide plate 21.
22 is placed on the rail 26 provided below,
It moves to the right at a predetermined speed by a belt or the like 35.

Please note that this attachment is short (31) as shown in the figure.
and long ones 33 are arranged alternately at predetermined intervals.

41 is a swing lever rotatably attached to the shaft 42;
44 is a cam whose peripheral surface is always in contact with the roller 45 provided on the swing lever 41, and the notch 46
It rotates in the direction of the arrow.

A spring 47 applies a counterclockwise rotational force to the swing lever 41.

50a, 50b, and 50c are PTP sheets.

The operation of the apparatus of this embodiment constructed as above will be explained as follows.

Note that FIGS. 3 to 5 are explanatory diagrams of the operation of the above embodiment.

In FIG. 3, the roller 44 of the swinging lever 41 is connected to the cam 4.
5, the swing lever 41 is in contact with the circumferential surface of the spring 4.
7 and is stopped in the illustrated state.

Now, when the disk 1 rotates in the direction of the arrow and one platform 3 comes just before it becomes parallel to the guide plate 21, the tip of the oscillator 5 hits the side surface 43 of the oscillating lever and resists the spring 9. The presser plate 11 rotates counterclockwise, and the presser plate 11 that moves together with the presser plate 11 also rotates counterclockwise to create a gap between the presser plate 11 and the upper surface of the platform 3.

In this state, the FTP sheet is located on the left side of the disk 1 as shown in the figure.

When the disk 1 rotates further and the upper surface of the platform 3 reaches the same plane as the guide plate 21 as shown in FIG. 4, the disk 1 stops at this position.

At this time, since the attachment 31 is moving to the right in the figure, the PTP sheet 50a sent thereto passes through the gap between the top surface of the mounting table 3 and the presser plate 11 and is placed on the mounting table 3.

When the PTP sheet 50a is fed to a predetermined position on the table, the roller 44 of the swinging lever moves as shown in FIG.
falls into the notch 46 of the cam 45, and the swing lever 41 is pulled by the spring 47 and rotates counterclockwise about the shaft 42 by θ.

Therefore, the tip of the oscillator 5 comes off the oscillating lever 41, is pulled by the spring 9, and rotates clockwise, and the holding plate 11 that moves together with this comes into contact with the upper surface of the FTP sheet 50a.

At the same time, the disc 1 begins to rotate in the direction of the arrow, and when the tip of the swing claw 5 passes the tip of the swing lever, the roller 44 of the swing lever comes into contact with the circumferential surface of the cam 45 again, causing the swing lever 41 to move. Rotate clockwise to return to the original state.

On the other hand, the FT sandwiched between the other mounting table 4 and the holding plate 12
As shown in FIG. 5, as the disc 1 rotates, the P seat) 50b is reversed and faces downward, and its tip is connected to the upper guide plate 24.
The disk 1 stops while resting on the .

When the disk 1 rotates, the FTP sheet 50b is held down on both sides by the mounting table 4 by the holding plate 12, so there is no risk of the FTP sheet 50b jumping out or falling due to the centripetal force.

At this time, the long attachment 33 moves to the right along the path 23, and the FTP sheet 50c
When they are directly below point b, both FTP sheets 50b and 50c are sent out to the right (see Fig. 2).

In this state, the upper PTP sheet 50b is pressed by the presser plate 12, but since the spring pressure of the presser plate 12 is weakened, it can be fed out with the attachment 33 as it is.

Returning to FIG. 4 again, when the FTP sheet 50a is held on the platform 3 and the disk 1 rotates 90 degrees and stops, the short attachment 31 moves from below the platform 3 along the path 23 to the double-ended plate 1. , 1 and move to the right.

While disk 1 is rotating and stopping, the next long attachment feeds the FTP sheet, and after a certain interval, the short attachment feeds the next FTP sheet, resulting in the state shown in Figure 5, and the disk 1 rotates the next 90 degrees and stops, the above operation is performed again, and in this way, two FTP sheets can be continuously combined and sent out.

In the above explanation, a case has been described in which the movement of an oscillator cooperating with a presser plate is controlled by a combination of a oscillating lever and a cam, but the means for controlling the oscillator is not limited to that of the embodiment. , or by other means.

Further, in the above embodiment, a case has been described in which the disk is rotated in 90 degree increments and stopped for a certain period of time, but the disk may be rotated in 180 degree increments and stopped for a certain period of time in between.

Furthermore, although we have explained the case where two platforms are installed on the disk, it is possible to increase the speed by installing four platforms by changing the rotational speed of the disk, the opening and closing timing of the cam, the movement speed of the attachment, etc. You can also do that.

In the explanation of this embodiment, the configuration and operation of one set of reversing devices have been described, but it goes without saying that in actual work, multiple sets of these can be installed in parallel and driven by the same power source. .

As described in detail above, the present invention provides an even number of platforms for placing FTP sheets on the opposing surfaces of a pair of disks configured to repeat the operation of rotating a predetermined angle and then stopping for a predetermined time, and A pair of FTP sheet guide plates are provided that extend in the gap between the disks in the diametrical direction of the disks, and an FTP sheet feeding piece with a short vertical portion that moves in a state projecting upward through a passage between the guide plates. FTP sheet extrusion Katayoshi with long vertical parts are provided alternately at a predetermined interval, and an FTP sheet holding plate, which is biased toward the above-mentioned table by a spring, is pivotally attached to the disk, and the FTP sheet extrusion circle is A swing lever is provided to open the inlet end of the FTP sheet holding plate on the supply side to the plate, and the upward facing FTP sheet is held between the table and the FTP sheet holding plate and is flipped downward to the inverted position side. with a downward facing FTP sheet;
The upward-facing FTP sheet located directly below is extruded simultaneously by the PTP sheet extrusion piece, which not only simplifies the mechanism compared to conventional devices, but also makes it easier to feed and hold the FTP sheet to the mounting table. It is suitable for mass production because it is smooth and reliable, and speedy processing is also possible.
