Abstract

PROBLEM TO BE SOLVED: To manufacture a PTP sheet which can be provided with an edgeless roundness around each of small sheet pieces cut off per unit of a pocket part. SOLUTION: Holes 81, 82 are formed by punching a PTP film 16 using a hole puncher in a hole punching process so that an edgeless roundness is formed on the periphery of each of small sheet pieces. In a next slit molding process, each of slits 84, 85 is molded in the PTP film 16 with the help of a slit molder. Further, in a following sheet punching process, every PTP sheet is punched as a unit using a sheet puncher. In this case, since gauge holes 83 are punched beforehand by the hole puncher, it is possible to perform the slit molding and the sheet punching work using the gauge holes 83 as a reference in an after- process. Thus the holes 81, 82, the slits 84, 85 and the sheet punching part can be correctly positioned.

At the end of the PTP sheet 28, a tag section 86 on which identification information such as a lot number is engraved is attached.

[0003] At the four corners of the sheet piece 87,
As shown in FIG. 8B, a right-angled edge 91 is formed, but it is preferable that the edge 91 is not provided in consideration of the convenience of the user using the PTP sheet 28.

Therefore, as shown in FIG. 7B, the production of the PTP sheet 28 in which the four corners of the sheet small piece 87 are rounded without forming the edge 91 on the sheet small piece 87 has been considered for some time. ing. As an apparatus for manufacturing the PTP sheet 28 having such a roundness 88,

The movable mold 62 is provided with a marking portion for marking identification information such as a lot number at a predetermined position of the PTP film 16 by printing or the like. Note that the marking device 24 is not provided with the gauge pins 56 and the like.

Next, the sheet punching device 27 will be described. As shown in FIGS. 2 and 6, the sheet punching device 27
Has a fixed mold 71 and a movable mold 72. Movable mold 7
A drive / transmission mechanism 73 (see FIG. 2) is connected to 2 and is switched between a working position close to the fixed mold 71 and a standby position separated from the fixed mold 71. As the drive / transmission mechanism 73, an appropriate one such as a motor, a fluid pressure cylinder, and a cam transmission mechanism can be used. In FIG. 6, for convenience, the movable die 72 is switched between the working position and the standby position by linear movement.

The movable die 72 is provided with a pair of punching blades 74 projecting in a state of being arranged in the width direction. Each punching blade 74 is PT
The P sheet 28 is formed in a frame shape along the outer shape. On the other hand, a pair of punching holes 74 are formed in the fixed mold 71 so as to correspond to the punching blades 74.

The movable mold 72 has a pair of gauge pins 76 protruding outside the pair of punching blades 74. The gauge pins 76 are provided at positions corresponding to the unnecessary film portions 32 at both ends in the width direction of the PTP film 16. More specifically, the gauge pins 76 are provided at positions corresponding to the gauge punching punch 49 of the punch hole punching device 20. Have been. Gauge pin 7
Reference numeral 6 denotes a cylindrical body portion 76a and a tapered tapered portion 76b formed on the tip side thereof.

On the other hand, the fixed mold 71 has a gauge hole 77 into which the gauge pin 76 is fitted when the movable mold 72 is moved to the working position. The gauge hole 77 has a shape in which the body portion 56a of the gauge pin 56 fits exactly. The gauge pin 76 and the gauge hole 77 constitute a positioning means.

Each punching blade 74 from the surface of the movable die 72
The protrusion amount of the PTP film 16 is uniform, and the PTP film 16 is punched out by the punching blades 74 at a time in units of the PTP sheet 28 as the movable mold 72 moves to the working position.

On the other hand, the gauge pin 76 is set so as to have a larger protrusion amount than each punching blade 74. More specifically, the tip position of each punching blade 74 corresponds to the position of the body 76a of the gauge pin 76. Therefore, each punching blade 74 has P
Before contacting the surface of the TP film 16, the gauge pins 7
6 is guided into the gauge hole 77, and the body portion 76 a of the gauge pin 76 is exactly fitted in the gauge hole 77.

The procedure for manufacturing the PTP sheet 28 shown in FIG. 7A by the PTP packaging machine 1 configured as described above will be described. The following description focuses on the main steps after the configuration.

The PTP film 16 first goes through a punching step. In the punching step, a punching apparatus 20 is used. That is, as the movable die 42 of the punch hole punching device 20 moves from the standby position to the work position, the corresponding punches 47, 48 are fitted into the respective punch holes 44, 45 of the fixed die 41. Is done. As a result, chip pieces conforming to the shapes of the punches 47 and 48 are punched, and as shown in FIG. 1, the PTP film 16 has a shape in which four concave curves with four holes are arranged in a diamond shape ( Stardust shape)
And a total of 18 holes 81 are formed for two sets, and two sets of holes 82 are formed by halving the stardust shape by one diagonal line (semi-stardust shape). Is done.

Similarly, a corresponding punching punch 49 for each gauge is fitted in each punching hole 46 for each gauge of the fixed die 41. As a result, as shown in FIG.
6, a pair of gauge holes 83 are formed in the unnecessary film portions 32 located at both ends in the width direction of the PTP film 16 as alignment portions having a circular hole shape.

When the punching step is completed, the process proceeds to a slit forming step. In the slit forming step, a slit forming device 23 is used. That is, the slit forming apparatus 2
As the movable mold 52 moves from the standby position to the work position, first, the gauge pin 56 is moved to the gauge hole 57.
Is inserted into. Before the gauge pin 56 is inserted into the gauge hole 57, the PT formed in the punch hole punching process is used.
It is inserted into the gauge hole 83 of the P film 16.

Here, the slit forming operation is performed during an intermittent feed interval (temporary stop) by the intermittent feed rolls 18 and 22. At the time of the temporary stop, as shown in FIG. The positional relationship between the temporary stop position of the gauge hole 83 and the gauge hole 57 is set in advance so that the hole 83 is located slightly beyond the gauge hole 57 of the fixed mold 51. The misalignment between the gauge hole 83 and the gauge hole 57 is caused by the gauge hole 5 of the gauge pin 56.
7 is set such that the tip of the tapered portion 56b is located at a position where it can be inserted into the gauge hole 83 when it is inserted into the gauge hole 83.

Therefore, when inserting the gauge pin 56 into the gauge hole 57, first, the tapered portion 56 b is inserted into the gauge hole 83 of the PTP film 16. Then, when the gauge pin 56 further moves to the work position side, the gauge pin 56 shown in FIG.
As shown in FIG.
The PTP film 16 is slightly pushed back to the upstream side so that 6a is fitted.

Even if the PTP film 16 is pushed back, the PTP film 16 on the downstream side is maintained in a tensioned state only by a slight movement of the tension roll 21 on the downstream side. On the other hand, although the PTP film 16 slightly bends on the upstream side, it is only negligible when viewed from the whole PTP packaging machine 1.

As described above, the gauge holes 57 and 83
The reason why the positional relationship with the intermittent feeding roll 1 is shifted in advance is that the PTP film 16 is pulled to the downstream side.
8 is impossible due to the presence of the tension roll 21 on the upstream side, and the PTP film 16 can be moved to the upstream side regardless of the thermal expansion, thermal contraction, and the like of the PTP film 16. It is. That is, if the positions of the gauge hole 57 and the gauge hole 83 are aligned in advance, if the PTP film 16 thermally contracts,
This is to prevent the position shift from being unable to be eliminated.

Thus, the body 56 of the gauge pin 56
When the positions of the gauge holes 83 and the gauge holes 57 are aligned by a, the movable mold 52 is further moved to the work position side, so that the slitter blades 54 and 55 come into contact with the PTP film 16. As a result, as shown in FIG.
A vertical slit 84 and a horizontal slit 85 are formed in the P film 16 as separating lines. Since the alignment is performed immediately before the gauge pin 56, the gauge hole 57, and the gauge hole 83 are arranged at the same position,
The slits 84 and 85 are completely aligned with the acute angles of the holes 81 and 82.

When the slit forming step is completed, the process proceeds to the engraving step. In this marking process, a marking device 24 is used. That is, as the movable mold 62 of the marking device 24 moves from the standby position to the work position, identification information such as a lot number is stamped at a position corresponding to the tag unit 86 in FIG. In the engraving step, the engraving is merely performed, and fine positioning as in the slit forming step is not required. Therefore, an accurate position using the gauge pin 56 or the like is not used.

When the engraving step is completed, the process proceeds to a sheet punching step. In the sheet punching process, a sheet punching device 27 is used. That is, as the movable mold 72 of the sheet punching device 27 moves from the standby position to the work position, first, the gauge pin 76 is inserted into the gauge hole 77. Before the gauge pin 76 is inserted into the gauge hole 77, the PTP film 16 formed in the punch hole punching process is formed.
Is inserted through the gauge hole 83.

Here, the sheet punching operation is performed during the intermittent feed interval (temporary stop) by the intermittent feed roll 22. At this temporary stop, the PTP film 16 is removed in the same manner as in the slit forming step. Gauge hole 83
However, the positional relationship between the temporary stop position of the gauge hole 83 and the gauge hole 77 is set in advance so that the position is slightly over the gauge hole 77 of the fixed die 71. The misalignment between the gauge hole 83 and the gauge hole 77 is set so that the tip of the tapered portion 76b can be inserted into the gauge hole 83 when the gauge pin 76 is inserted into the gauge hole 77.

Therefore, when the gauge pin 76 is inserted into the gauge hole 77, the tapered portion 76b is first inserted into the gauge hole 83 of the PTP film 16. When the gauge pin 76 further moves to the work position side, the gauge hole 8 is moved.
3 so that the body portion 76a of the gauge pin 76 is fitted therein.
The PTP film 16 is slightly pushed back to the upstream side.

Even when the PTP film 16 is pushed back, the tension roll 25 is slightly moved on the downstream side, and the PTP film 16 on the downstream side is kept in tension. On the other hand, although the PTP film 16 slightly bends on the upstream side, it is only negligible when viewed from the whole PTP packaging machine 1.

As described above, the gauge holes 77 and 83
The positional relationship between the gauge holes 57 and 83 is shifted in advance for the same reason as in the slit forming process.

Thus, the body 76 of the gauge pin 76 is
With the positions of the gauge holes 83 and 77 aligned according to a, the movable die 72 is further moved to the work position side, so that each punching blade 74 punches the PTP film 16. As a result, the PTP sheet 28 as shown in FIG.
Separated from the TP film 16. The gauge pin 7
6, since the alignment is performed immediately before the gauge hole 77 and the gauge hole 83 are arranged at the same position,
The periphery of the TP sheet 28 is completely aligned with the acute angle portions of the holes 81 and 82.

As described above, the PTP sheet 28 as shown in FIG. 7A can be obtained. This PT
When the P sheet 28 is cut into sheet pieces 87 in pocket units 7 at the slits 84 and 85, the P sheet 28 becomes a smooth circular arc having rounded corners 88 at four corners as shown in FIG.

The four corners of such a small sheet piece 87 are rounded.
The PTP sheet 28 having the hole 8 is formed by punching out a gauge hole 83 in a punching hole punching process, and then performing a slit forming process and a sheet punching process, which are subsequent processes, based on the punched hole. Production on a base becomes possible.

[0093] Instead of forming the slits 84 and 85 in the slit forming step, a perforation may be formed. This is because each slitter blade 54,
Use a sewing machine blade instead of
It can be easily changed by forming a concave groove into which the sewing machine blade bites.

Further, instead of manufacturing two PTP sheets simultaneously in the width direction of the PTP film 16, three or more PTP sheets may be manufactured or one PTP sheet may be manufactured at a time.

Further, a total of ten sheet small pieces 87 each having five PTP sheets 28 in the width direction and two rows in the transport direction are provided per sheet, but the number in the width direction and the row in the transport direction are provided. The number may be set arbitrarily.

Further, the gauge hole 83 is punched simultaneously with the holes 81 and 82 in the punch hole punching step.
The gauge hole 83 may be punched in a step before the punch hole punching step. In this case, in the punch hole punching step, as in the case of the slit forming step or sheet punching step which is the subsequent step, each hole is adjusted in a state where the positional relationship between the gauge pin and the gauge hole 83 is aligned using the gauge pin. It suffices to punch through 81 and 82.

Also, the gauge hole 83 for positioning is formed by PTP.
Although a pair is provided at both ends in the width direction of the film 16, at least one gauge hole 83 is sufficient for positioning. However, it is preferable to provide a pair in order to secure positioning accuracy. Of course, three or more gauge holes 83 may be used.

Further, instead of the positioning gauge hole 83, a gauge notch having a semicircular shape, for example, may be formed at the end in the width direction of the PTP film 16. Further, a gauge projection may be provided, but in this case, it becomes more difficult to manufacture the PTP sheet 28 than in the above embodiment.

Further, the gauge hole 83 for positioning does not have to be circular. For example, a polygonal shape or the like can be changed.
In addition to facilitating the production of manufacturing equipment such as
Since the guides 6b and 76b are easily guided, positioning is also reliable and easy.
