  In the method described in the background art, when filling the tablet 91 into the pocket portion 93, the rotary drum 90 is rotated at a constant speed in synchronization with the container film 89. On the other hand, when the tablet 91 is supplied from the tablet supply chute 94 to the receiving recess 92, it is necessary to temporarily stop the rotation of the rotary drum 90. For this reason, the tablet 91 cannot be supplied to the storage recess 92 at the timing of filling the pocket portion 93. That is, the position (angle) of the accommodating recess 92 in the rotary drum 90 at the time of tablet supply is limited. Accordingly, the angle at which the tablet supply chute 94 can be installed with respect to the rotary drum 90 is also limited.

  On the other hand, an optimal installation angle of the tablet supply chute 94 with respect to the rotary drum 90 is required from the shape and size of the tablet 91 or the specification of the tablet supply chute 94. For this reason, the optimal installation angle of the tablet supply chute 94 may not match the angle at which the tablet supply chute 94 can be installed. In this case, the tablet 91 cannot be supplied to the storage recess 92 at an optimum angle, and a problem due to the deterioration of the storage posture of the tablet 91 occurs, or the shape and size of the tablet 91 that can be filled are limited. There is a risk of losing.

Accordingly, the filling material can be reliably supplied to the rotary drum. As a result, it is possible to suppress problems due to the deterioration of the housing posture and to supply articles having various shapes and sizes. In addition, it is possible to manufacture PTP sheets for filling objects of various shapes and sizes.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 2, in this embodiment, the PTP packaging machine 1 is equipped with a filling device for filling materials such as tablets, so that the pocket portion provided in the PTP sheet is filled in the PTP packaging machine 1. The tablet as a product is filled.

  The PTP packaging machine 1 automatically wraps tablets 2 (see FIG. 1 and the like) on a container film. Specifically, a film 3 such as polypropylene or PVC is fed into the heating device 7 and the molding device 8 by the film feed roll 4 and the tension rolls 5 and 6, and the pocket portion 9 for filling the tablet 2 (see FIG. 1) is formed into a film 3. Then, when the container film 10 in which the pocket portions 9 are formed is sent to the bottom of the filling device 11 that is a means for filling the tablets 2, the filling devices 11 automatically fill the tablets 2 in the pocket portions 9. Is done.

  In addition, after the tablet 2 is filled, an inspection is performed in order to find out the presence or absence of the tablet 2 in each pocket portion 9, the defect of the filled tablet 2, the mixing of foreign matter, and the like. The inspection is performed by an inspection apparatus including a CCD camera 12 as an imaging apparatus, an illumination 13 as an illumination apparatus, and the like.

  Further, an aluminum sealing film 14 is fed through the tension rolls 15 and 16 onto the container film 10 in which the pockets 9 are filled with the tablets 2 and fixed by the pair of seal rolls 17 and 18. The Thus, a long PTP sheet 19 in which the tablets 2 are filled in the pocket portions 9 is manufactured. The long PTP sheet 19 is cut into a sheet shape, and then sequentially sent to a defective sheet discharge mechanism, a PTP sheet stacking mechanism, and the like (not shown).

  Now, FIG. 1 has shown the filling apparatus 11 applied to the PTP packaging machine 1 in this Embodiment. The filling device 11 is provided close to the first rotary drum 21 for filling the tablet 2 with the tablet 2 and immediately above the first rotary drum 21, and receives the tablet 2 on the first rotary drum 21. A second rotary drum 22 for delivery and a supply chute 23 as supply means for supplying tablets to the second rotary drum 22 are provided.

  Each of the first rotary drum 21 and the second rotary drum 22 includes a first rotary shaft 25 and a second rotary shaft 26, and is a cylindrical rotary body having the first and second rotary shafts 25 and 26 as central axes. is there. The first rotating shaft 25 has a base end portion connected directly or indirectly to a servo motor (not shown). The second rotating shaft 26 is connected to the first rotating shaft 25 by a rotation connecting means (not shown), and is rotated in the reverse direction as the first rotating shaft 25 rotates. The rotational speed of the second rotating shaft 26 is set so that the peripheral speed of the first rotary drum 21 and the peripheral speed of the second rotary drum 22 are the same. In the present embodiment, the first rotary drum 21 and the second rotary drum 22 have substantially the same diameter, and the first and second rotary shafts 25 and 26 are rotated at the same rotational speed.

  Further, the first rotating shaft 25 and the second rotating shaft 26 are connected by a substantially L-shaped holder 27. A first rotating shaft 25 is set near the L-shaped bent portion of the holder 27, and a second rotating shaft 26 is set on one end side of the holder 27. A curved long hole 27 a is formed on the other end side of the holder 27. A retaining screw 28 is fitted in the long hole 27a, and the holder 27 can be fixed to a base (not shown). The holder 27 is tiltable about the first rotation shaft 25 and is configured to be able to move the position of the second rotary drum 22 with respect to the first rotary drum 21. Note that the distance between the rotation center of the first rotary drum 21 and the rotation center of the second rotary drum 22 is always constant by the holder 27. Then, the second rotary drum 22 is fixed at a predetermined position by tilting the holder 27 at a predetermined angle and fixing the retaining screw 28 to the base.

  On the outer peripheral surface of the first rotary drum 21, a large number of receiving pockets 29 are formed as holding parts for holding and holding the tablets 2. The storage pockets 29 are regularly arranged at predetermined intervals in the circumferential direction and the axial direction of the first rotary drum 21. The depth of the accommodation pocket 29 is formed such that a part of the tablet 2 protrudes from the outer peripheral surface of the first rotary drum 21. Thereby, the tablet 2 can be sufficiently protruded from the accommodation pocket 29 while being stably held.

  A vent hole 30 as a suction hole is formed in the center of the bottom of each accommodation pocket 29 in the radial direction of the first rotary drum 21. A plurality of air passages 31 are provided along the axial direction of the first rotary drum 21 so as to surround the periphery of the first rotary shaft 25, and each air passage 31 extends along the axial direction of the first rotary drum 21. Are communicated with each vent hole 30 in the same row. Each air passage 31 is configured to be connectable to a suction passage from a suction device as suction means (not shown), and suction and suction can be released for each air passage 31.

  Therefore, when the suction device is in the operating state, the air in the air passage 31 is sucked and is in a substantially vacuum state. For this reason, the series of vent holes 30 communicated with the vent passage 31 can suck the tablets 2 accommodated in the respective accommodation pockets 29 facing the opening portions and allow the tablets 2 to be adsorbed to the respective accommodation pockets 29.

  Moreover, the 1st rotary drum 21 is arrange | positioned so that the container film 10 conveyed in a horizontal direction may adjoin at the lowest point. The tablet 2 transferred to the lower portion of the first rotary drum 21 is configured to be filled in the pocket portion 9 of the container film 10 below the first rotary drum 21.

  On the other hand, on the outer peripheral surface of the second rotary drum 22, a large number of receiving recesses 33 are formed as holding parts for holding and holding the tablets 2. The accommodating recess 33 accommodates substantially the entire tablet 2. The receiving recesses 33 are regularly arranged so as to be the same as the arrangement interval of the receiving pockets 29 in the first rotary drum. The accommodating recess 33 is configured to coincide with the accommodating pocket 29 at a position where the first rotary drum 21 and the second rotary drum 22 are closest to each other.

  Near the side of the second rotary drum 22, a half-moon guide member 36 is installed and fixed along the outer peripheral surface of the second rotary drum 22. The half-moon guide member 36 is a member for guiding the tablet 2 accommodated in the accommodating recess 33 of the second rotary drum 22 without dropping or deviating.

  In the vicinity of the upper portion of the second rotary drum 22, a supply chute 23 is provided for supplying the tablet 2 to the receiving recess 33 by utilizing natural fall due to gravity. The supply chute 23 is disposed on the back side (the position after passing the top for a while) with respect to the rotation direction of the second rotary drum 22. In the present embodiment, the supply chute 23 is disposed corresponding to the housing recess 33 that reaches a position that is rotated and moved by a predetermined angle a from directly above the second rotary drum 22. The inside of the supply chute 23 is hollow, and is formed so that the tablets 2 can be stacked in a vertical direction in a vertical row. The upstream (upper) side of the supply chute 23 is connected to the tablet 2 supply unit, and the downstream side is an opening so that the loaded tablets 2 can be discharged.

  Here, the case where the tablet 2 is filled in the pocket portion 9 of the container film 10 conveyed at a constant speed in the filling device 11 will be described. First, the servo motor is operated in synchronization with the conveyance of the container film 10. Accordingly, the first rotary drum 21 and the second rotary drum 22 are rotated in synchronization with the transfer speed of the container film 10. Then, above the second rotary drum 22, when the accommodation recess 33 reaches the vicinity of the opening of the supply chute 23, the rotation of the second rotary drum 22 is temporarily stopped or slowed down. Then, the tablet 2 falls from the supply chute 23 and one tablet 2 is accommodated in each accommodating recess 33. The rotation stop or the low speed rotation of the second rotary drum 22 is performed every time the accommodating recess 33 reaches the vicinity of the opening of the supply chute 23. Further, in synchronization with the rotation of the second rotary drum 22, the rotation speed of the first rotary drum 21 is also changed.

  After the tablet 2 is stored, the tablet 2 stored in the storage recess 33 is transferred toward the first rotary drum 21 along the half-moon guide plate 36 as the second rotary drum 22 further rotates. . On the other hand, in the first rotary drum 21, the storage pocket 29 reaches the position where the first rotary drum 21 and the second rotary drum 22 are closest to each other in accordance with the storage recess 33 in which the tablet 2 is stored. It has become. Here, in the accommodation pocket 29 facing the tablet 2 accommodated in the accommodation recess 33, the ventilation path 31 communicating with the ventilation hole 30 is sucked by the suction device. Then, the tablet 2 accommodated in the accommodation recess 33 is attracted to the accommodation pocket 29 and moved to the first rotary drum 21.

  The tablet 2 adsorbed and held in the storage pocket 29 is transferred downward as the first rotary drum 21 rotates. During this transfer, the tablet 2 is held in a state where it is adsorbed in the storage pocket 29 without dropping from the storage pocket 29.

  Below the first rotary drum 21, the tablet 2 accommodated in the accommodation pocket 29 approaches the container film 10 to be conveyed. While the adsorbed tablet 2 reaches from the vicinity of the lowest point to the lowest point, the first rotary drum 21 is rotated at a constant speed in synchronization with the conveyance speed of the container film 10. In the position directly below the first rotary drum 21, the pocket portion 9 and the accommodation pocket 29 are set to face each other. For this reason, the tablet 2 accommodated in the accommodation pocket 29 at the lowest point of the first rotary drum 21 coincides with the pocket portion 9.

  Further, at the lowest point of the first rotary drum 21, the first rotary drum 21, the container film 10, and the like so that a part of the tablet 2 protruding from the outer peripheral surface of the first rotary drum 21 enters the pocket portion 9. Are arranged close to each other. For this reason, the tablet 2 conveyed below the first rotary drum 21 is conveyed while entering the pocket portion 9 of the container film 10 (see FIG. 3). During this time, as described above, since the first rotary drum 21 is rotated at a constant speed in synchronization with the transport speed of the container film 10, the tablet 2 does not interfere with the container film 10 and does not interfere with the first rotary drum 21. To the lowest point. During this time, the second rotary drum 22 is rotated at a constant speed similar to that of the first rotary drum 21. For this reason, the housing recess 33 is set so as not to reach a position that requires rotation stop or low-speed rotation with respect to the supply chute 23. Then, when the tablet 2 reaches the lowest point of the first rotary drum 21, the suction of the air passage 31 is released. Then, the adsorption of the tablet 2 is released, and the tablet 2 naturally falls and is filled in the pocket portion 9 of the container film 10.

  It is not always necessary to rotate the first rotary drum 21 at the constant speed until the next tablet 2 starts to enter the pocket portion 9 after the adsorption is released. For this reason, in this Embodiment, in order to supply the tablet 2 to the accommodation recessed part 33 from the supply chute 23 in the said time, rotation of the 2nd rotary drum 22 is stopped or made into low speed. Here, the position (angle) at which the accommodation recess 33 arrives at a timing at which the rotation of the second rotary drum 22 can be stopped or rotated at a low speed is uniquely determined. For this reason, for example, the supply chute 23 is installed corresponding to the accommodating recess 33 that reaches a position rotated by a predetermined angle a from right above the second rotary drum 22.

  However, depending on the shape and size of the tablet 2 and the specifications of the supply chute 23, it may be better to install the supply chute 23 at a different angle than the predetermined angle a. For example, as shown in FIGS. 4A and 4B, the optimum installation angle of the supply chute 23 may be larger or smaller than a predetermined angle a, such as an angle b and an angle c. When the position of the supply chute 23 is changed, it is necessary to cause the receiving recess 33 to reach the angle b or the angle c at a timing at which the rotation of the second rotary drum 22 can be stopped or rotated at a low speed.

  Here, a method for setting the position of the housing recess 33 in accordance with the optimum installation angle of the supply chute 23 will be described. First, the retaining screw 28 of the holder 27 is once loosened, and the holder 27 is tilted about the first rotating shaft 25 of the first rotary drum 21. As a result, the position of the second rotary drum 22 is moved around the first rotary drum 21 as shown in FIGS. Even when the second rotary drum 22 is moved, the tablet 2 is transferred from the second rotary drum 22 to the first rotary drum 21 at a position where the first rotary drum 21 and the second rotary drum 22 are closest to each other. The relationship that the accommodation recess 33 and the accommodation pocket 29 are opposed to each other is maintained. For this reason, the angle of the accommodation recess 33 on the second rotary drum 21 is changed depending on the position of the second rotary drum 21 with respect to the first rotary drum 21. Then, by fixing the second rotary drum 22 to an appropriate position with the retaining screw 28, the housing recess 33 is set to the angle b or the angle c when the rotation of the first and second rotary drums 21 and 22 is stopped or at a low speed. Can be reached. It is desirable to change the half-moon guide plate 36 according to the position of the supply chute 23.

  As described above, the accommodation recess 33 can be reached at an appropriate position near the lower portion of the supply chute 23 in accordance with the optimal arrangement angle of the supply chute 23 by simply moving the position of the second rotary drum 22. It has become. Therefore, the arrangement angle of the supply chute 23 can be optimized.

The accommodation pocket 29 may be formed deep so as not to protrude. Further, a rotary drum in which the accommodation pocket 29 is omitted and the vent hole 30 is opened on the outer peripheral surface may be applied.

  (D) Although the first rotary drum 21 can adsorb the tablet 2, it does not include a suction mechanism such as the vent hole 30 or the vent path 31, and is installed near the side of the second rotary drum 22. Such a half-moon guide member may also be installed near the side of the first rotary drum 21.

  (E) Further, the second rotary drum 22 cannot adsorb the tablet 2, but may be configured to be provided with a ventilation path and a vent hole as in the case of the first rotary drum 21. In this case, when the tablet 2 adsorbed and transferred by the second rotary drum 22 faces the storage pocket 29, the adsorption of the tablet 2 by the second rotary drum 22 is released. Thereby, delivery of the tablet 2 from the 2nd rotary drum 22 to the 1st rotary drum 21 can be performed smoothly.

  (F) In the above-described embodiment, the first and second rotary drums 21 and 22 are rotated at a constant speed and stopped or decelerated when the tablet 2 is supplied. In the range, acceleration or reverse rotation, or stop or deceleration at other timings may be performed.

  (G) Although the relationship between the interval in the rotation direction of the accommodation pocket 29 of the first rotary drum 21 and the interval in the transfer direction of the pocket portion 9 of the container film 10 is not particularly mentioned, the rotation of the first rotary drum 22 By controlling the speed, it is possible to cope with the same interval or different intervals.
