Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tablet filling device, and more particularly to a filling device for blistering irregularly shaped tablets.

[0002]

[Prior art]

 In a conventional filling device for blister-packing tablets, a shutter for supplying the tablets to the device, and a shutter and a large number of pockets for holding the tablets are interposed between the formed packaging film and put the tablets on the outer peripheral surface. There is provided a known roll device having a rotatable roll having a large number of pockets formed therein, and a claw portion for feeding the tablets in the chute one by one in synchronization with the rotation of the roll.

By the way, when a tablet, especially a deformed tablet is supplied to a filling device through a shutter, a so-called bridging occurs in which tablets that are aligned and moved in the shutter are overlapped and clogged, and In some cases, it became stagnant and continuous filling became impossible. Therefore, it was necessary to stop the device and remove the bridge each time, which was the main cause of the increase of loss time and the damage rate of tablets.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems in the conventional filling device for blister packaging of tablets, and provides a tablet filling device capable of reducing loss time and damage rate of tablets with less generation of bridges. To aim.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention rotatably interposes between a chute and a packing film, and a chute for tablet supply, which has a tablet supply port at one end and is connected to a tablet hopper at the other end. And a roll for individually distributing the tablets supplied from the chute into the pockets of the packaging film, and a roll provided adjacent to the tablet supply port of the chute, in synchronization with the rotation of the roll. A tablet filling device having a shutter device having a claw portion for individually feeding the tablets, and a mounting plate for supporting the chute is provided adjacent to the chute, and one end of the chute is provided. It is configured to be fixed to the mounting plate, and a vibration generator for applying vibration to the chute via the mounting plate is mounted on the mounting plate.

[0006]

[Action]

 In the above configuration, the tablets are supplied to the roll via the chute. In this case, vibration is applied to the chute by the mounting plate to facilitate the movement of the tablet in the chute and suppress the occurrence of tablet clogging.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a tablet filling device 1 according to the present invention is illustrated. Here, 2 is a chute for supplying the tablet a to the roll, 3 is a mounting plate that supports the chute, 4 is a packaging film, 5 is a tablet that receives the tablet a from the chute 2 and supplies it to the packaging film 4, a rotation A roll 6 having a well-known structure supported so as to be possible is a shutter device having a well-known structure having a claw portion 61 for supplying the tablets a in the chute one by one in synchronization with the rotation of the roll.

The chute 2 is entirely formed in the shape of a spring coil. The one end 21 is open toward the outer peripheral surface of the roll 5 at a position close to the roll 5 and is fixed to the mounting plate 3. On the other hand, the other end 22 extends in the direction opposite to the roll 5 and is connected to a known tablet hopper (not shown). The chute (hereinafter referred to as a spring short) 2 has an advantage that a tablet slides better than a conventional chute and a bridge is less likely to occur. The spring chute 2 is integrated from the other end 22 to the one end 21, and it is desirable that the one end 21 is mounted extremely close to the roll 5. This eliminates the need for a connecting portion such as a mouthpiece or a joint as in the conventional chute, and suppresses the occurrence of tablet clogging due to misalignment of the chute at the connecting portion. In this case, since the claw portion 61 of the shutter device 6 is provided with a gap b for moving in and out of the spring chute 2, the coil gap is slightly widened at a part of the one end 21. FIG. 2 is a diagram showing that state.

Returning to FIG. 1, a mounting plate 3 that holds the spring chute 2 in a predetermined position adjacent to the spring chute 2 is mounted on a frame (not shown) of the tablet filling device 1. One end 21 of the spring chute 2 is fixed to one end 31 of the mounting plate 3, while the other end 32 extends in a direction opposite to the roll 5 and is connected to the vibration generating device 33. There is. The vibration generating device 33 has a known structure for generating vibration pneumatically, electrically or mechanically, and transmits the vibration to the one end 21 of the spring chute 2 via the mounting plate 3. A guide 34 of the spring chute 2 is attached to the other end 32 of the attachment plate 3 on the side opposite to the vibration generator 33. The guide 34 appropriately guides the plurality of spring shoes 2 juxtaposed in the direction perpendicular to the plane of FIG.

A roll 5 is provided between one end 21 of the spring chute 2 and the packaging film 4. The roll 5 is similar to a known roll, and has a plurality of rows of pockets 52 formed on the outer peripheral surface thereof, and is rotatably supported by a known method. A cam 51 is attached to one end of the roll 5 coaxially with the roll 5.

A shutter device 6 is provided near the spring chute 2 and on the side facing the mounting plate 3. The shutter device 6 has an arm 62 rotatably supported by the frame 61, and a lever 63 is fitted into one end 621 of the arm 62. A claw portion 631 is formed at the tip of the lever 63. The claw portion 631 is synchronized with the rotation of the roll 5, that is, the cam 51, and is linked to the other end 622 of the arm 62. It is possible to move in and out of the spring chute 2 through the gap of the coil which is slightly widened and is provided in the spring chute 2 through the. Regarding the link mechanism 64 connecting the cam 51 and the other end 622 of the arm 62, Japanese Patent Application No. 53-97170 (Japanese Utility Model Publication No. 5-16107) filed by the same applicant as the present applicant. The explanation is omitted because it is basically the same as the mechanism disclosed in ().

The operation of the present invention having the above structure will be described. In FIG. 1, the tablet a in the tablet hopper moves from the other end 22 in the spring chute 2 to reach one end 21. Since the spring chute 2 originally has good tablet slippage and has no obstacles such as a mouthpiece, the occurrence of tablet bridges is suppressed, and the tablet a moves smoothly. Further, the vibration generated by the vibration generator 33 is transmitted to the one end portion 21 of the spring chute 2 through the mounting plate 3. As a result, the transfer of tablets is further promoted and the occurrence of bridges is further suppressed. At the one end 21 of the spring chute 2, the arm 62 of the shutter device 6 is driven by the link mechanism 64 in synchronization with the rotation of the cam 51 of the roll 5 to swing, whereby the claw portion 631 of the lever 63 is moved. The tablets a in the one end 21 are divided into individual tablets a and fed into the roll chute 5 through the gaps between the slightly widened coils of the spring shoot 2 into and out of the spring chute 2. The roll 5 is rotated in the direction of the arrow R and sequentially receives the tablets a in the pockets 52. The tablet in the pocket 52 is transferred to the packaging film 4 by the roll 5, and is sequentially sent into the molding pocket of the packaging film 4.

[0014]

[Effect of device]

 According to the present invention, as described above, the chute is a spring shoe for improving the sliding of the tablet, and the spring chute is vibrated during the movement of the tablet, so that the incidence of bridges in the sprinkling chute is kept low. In addition, since the spring chute is continuously integrated and the cap and joint are eliminated, it is possible to move the tablet more smoothly without core misalignment, which is one of the causes of bridging. It produces a working effect. Therefore, it is possible to reduce the loss time due to the stoppage of the device, reduce the tablet damage rate, and increase the operating speed of the device.
