The present invention relates to a preparation transfer device and a preparation printing device.

As a device for transporting solid preparations such as tablets and capsules, the configuration disclosed in Patent Document 1, for example, is known. As shown in Figure 4, this preparation transfer device 100 is provided with an alignment device 110 for aligning the solid preparation supplied from the chute 103 through the feeder 104, In addition, a first transport drum 120, an attitude change device 140, and a second transport drum sequentially receive and transport the solid preparation from the alignment device 110. ) (150) and a third transport drum (170) (No. 3 transfer drum).

As shown in a perspective view in Figure 5, the alignment device 110 allows the solid preparation supplied to the hopper 111 to move between the guide plates 112 and 113 by the vibration of the vibration guide 114. It is configured to fall into the formed guide groove 115. The solid preparation is aligned in an upright position by the guide groove 115 and is received in the pocket 123 formed on the outer peripheral surface of the first transport drum 120 in the same position. The posture of the solid preparation conveyed by the first conveying drum 120 is changed from a standing state to a lying state during conveyance by the posture change device 140. The second transport drum 150 and the third transport drum 170 adsorb and transport the solid preparation received in a horizontal position in the same position, and the exposed surface of the solid preparation each conveys is captured by a photographing device (photograph device). 160, 180) takes pictures and inspects the front and back of the solid dosage form.

: Japanese Patent Laid-open Publication No. 9-79986

The conventional preparation transport device 100 can print on the front and back of a solid preparation by installing a printing device corresponding to each of the second transport drum 150 and the third transport drum 170. If there are features such as secant lines on one side of the front and back of the solid dosage form, printing is done in accordance with the direction of these features, and also printing on the side where the features do not exist. It is desirable to have a direction of .

However, since the front and back sides of the solid preparation (i.e., whether the features of the solid preparation are exposed or not) received by the second transport drum 150 are random, feature detection of the solid preparation is performed in the transport direction rather than the second transport drum 150. While it needs to be performed on the upstream side, since the lateral rotation of the solid preparation is done in the attitude change device 140, it was difficult to perform feature detection during the transport of the solid preparation using the attitude change device 140. . For this reason, there is a demand for quickly translating a large number of solid preparations and making it easy to detect the characteristics of the solid preparation.

Therefore, the purpose of the present invention is to provide a preparation transport device that can quickly and reliably horizontally transport solid preparations, and furthermore, using this preparation transport apparatus, compact printing tailored to the characteristics of the solid preparation is possible.

This is achieved by a possible configured agent transport device.

In this agent transport device, the guide plate preferably extends so as to span the plurality of pockets along the outer circumferential direction of the transport roll.

In addition, the pocket preferably includes a standing support portion that supports the solid formulation in a posture supplied from the supply device, and a lateral support portion that supports the solid formulation in a horizontal posture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the attached drawings. Figure 1 is a schematic configuration diagram of a formulation printing device including a formulation conveyance device according to one embodiment of the present invention. The formulation conveying device 2 includes a conveying roll 20 that conveys a solid formulation by rotation in the direction of the arrow, and a supply device that supplies the solid formulation to the conveying roll 20. )(10). In the present embodiment, the solid preparation is a flat tablet, but it may be of any other shape having an aroma, and may be a capsule other than a tablet.

As shown in Figure 2, the supply device 10 includes a hopper 11 for storing the solid preparation F, and a drive source such as a drive motor or vibrator. ) A diaphragm 13 that is driven and vibrates by 12, and a plurality of vibration guide members that are fixed to the diaphragm 13 and vibrate integrally with the diaphragm 13. ) (14) and a plurality of guide plates (15) for guiding the solid preparation (F) toward the conveyance roll (20). A plurality of vibration guide members 14 are arranged at intervals along the axial direction of the conveyance roll 20, and the solid formulation F supplied between them is guided by vibration in the direction of arrow A. It is conveyed toward the plate (15).

The plurality of guide plates 15 are inserted with a slight gap between the vibration guide member 14 and the conveyance roll 20, and each guide plate 15 is inserted into the hopper at a distance in the axial direction of the conveyance roll 20. It is fixed within (11). The conveyance roll 20 is provided with a plurality of pockets 21 formed at equal intervals along the outer peripheral surface, and the solid formulation F conveyed from the vibration guide member 14 is moved between each guide plate 15. It passes through and is accommodated in the pocket 21. A plurality of pockets 21 are formed in the axial direction of the conveyance roll 20, and each pocket 21 is arranged to pass between a plurality of guide plates 15. Each guide plate 15 extends to span a plurality of pockets 21 along the outer circumferential direction of the conveyance roll 20 in order to secure a wide supply area of the solid preparation F to the pockets 21. .

The bottom of each pocket 21 of the conveyance roll 20 communicates with a suction path 23 extending in the axial direction through a communication path 22 extending radially inward. It is done. As each pocket 21 passes through the guide plate 15 by rotating the conveyance roll 20 in the direction of arrow B, the suction path 23 is aligned with the suction shoe 24, The received solid preparation (F) is aspirated and supported.

Figure 3 is an enlarged cross-sectional view showing the portion where the solid preparation (F) is supplied from the plurality of guide plates 15 to the conveyance roll 20. The solid formulation (F) is aligned between the guide plates (15) and accommodated in the pocket (21) of the conveyance roll (20). The pocket 21 is sized so that the solid preparation (F) can be moved laterally inside, but the upper edge of the solid preparation (F) with the lower edge in contact with the bottom of the pocket 21 is guided by the guide plate (15). The depth of the pocket 21 is set so that it contacts the lower part of the pocket 21 and supports the posture of the solid preparation F during supply.

The posture of the solid preparation (F) accommodated in the pocket (21) is such that a large number of solid preparations (F) can be efficiently accommodated in the pocket (21). It is desirable to have a standing posture following (S). For example, when the solid preparation (F) is a disc-shaped tablet, it is preferable that the radial direction of the solid preparation (F) follows the standing surface (S). In this case, the radial direction of the solid preparation (F) does not need to completely coincide with the standing surface (S), so that the solid preparation (F) passes smoothly between the guide plates (15, 15), as shown in Figure 3 As shown, it may be slightly inclined with respect to the standing surface S. Additionally, when the solid preparation (F) is a cylindrical capsule, it is preferable that the axial direction of the solid preparation (F) follows the standing surface (S).

The pocket 21 has a communication port 21a of the communication path 22 formed at the bottom, and the solid preparation F contained in the pocket 21 passes through the guide plate 15. Then, the solid preparation (F) is aspirated from the communication port (21a). Accordingly, the posture during supply of the solid preparation (F) is maintained more reliably.

In addition, the pocket 21 is provided with a standing support portion (2 lb) and a lateral support portion ( 21c) are formed respectively. The standing support portion 2lb is formed substantially parallel to the standing surface S of the conveyance roll 20, while the transverse support portion 21c is inclined with respect to the standing surface S. Since the solid preparation (F) accommodated in the pocket (21) is supported on the guide plate (15) at its edge with one side in contact with the standing support (2lb), this also allows the solid preparation (F) to be The posture during feeding is clearly maintained.

When the solid preparation (F) contained in the pocket (21) passes through the guide plate (15) by rotation of the conveyance roll (20), it is supported by suction in the communication port (21a) and is attached to the guide plate (15). All support of the edge portion is released, and the conveying roll 20 is tilted laterally in the axial direction within the pocket 21, so that the other side of the solid formulation F is tilted laterally by the support portion (as shown by the broken line in FIG. 3). It is supported by contacting 21c). In this embodiment, as shown in Fig. 1, a brush roll 16 is disposed on the downstream side of the hopper 11 in the conveyance direction, so that the solid formulation F from the pocket 21 protrudes. This is prevented by the brush roll (16). The solid preparation (F) that has passed through the brush roll (16) is checked by the protruding detection plate (25) to determine whether it is normally accommodated in the pocket (21) (for example, in the unaccommodated state of the solid preparation (F) or when two pieces are inserted). After the condition is detected, the transfer roll 20 passes through an arc-shaped limiting guide 26 arranged to partially cover the outer peripheral surface when viewed from the side. The solid formulation (F) in the pocket 21 can be turned sideways by the brush roll 16, but since it is forcibly turned sideways by the limit guide 26, it is surely in a sideways posture, and the detection roll (described later) It is supplied to the exit roll (30). Since the lateral movement of the solid preparation (F) in the pocket (21) can be naturally achieved due to the self-weight of the solid preparation (F), etc., it can be done without installing the brush roll (16) or limit guide (26). , the solid formulation (F) may be supplied to the detection roll 30 in a horizontal position.

The formulation transport device 2 having the above configuration is capable of supplying the solid formulation F to the pocket 21 in a predetermined position along the entire guide plate 15 of the supply device 10, By the rotation of the conveyance roll 20, the edge of the solid formulation F contained in the pocket 21 slides along the guide plate 15, and the posture of the solid formulation F being conveyed is maintained. Therefore, even when a plurality of solid preparations (F) are supplied from the supply device 10 to the conveyance roll 20, there is a risk that a plurality of solid preparations (F) will be simultaneously accommodated in the same pocket 21 of the conveyance roll 20. Since there is no, a large number of solid preparations (F) can be transported efficiently while preventing damage to the solid preparations (F). In addition, after the solid preparation (F) has passed through the guide plate (15), the solid preparation (F) can be quickly and reliably moved laterally within the pocket (21), making it possible to transfer the solid preparation (F) later by adsorption. The solid formulation (F) can be easily and reliably delivered to the detection roll (30).

The formulation printing device 1 shown in FIG. 1 includes, in addition to the above-mentioned formulation conveying device 2, a detection roll 30 that sequentially conveys the solid formulation supplied from the formulation conveying device 2 by rotation in the direction of the arrow. ), a first printing roll 40 and a second printing roll 50. Like the conveyance roll 20, the detection roll 30, the first printing roll 40, and the second printing roll 50 are formed with a plurality of pockets (not shown in the drawing) along the outer circumferential direction and the axial direction. and each pocket is connected to a suction passage (not shown in the drawing). The suction paths of the detection roll 30, the first printing roll 40, and the second printing roll 50 are sucked by a suction shoe (not shown in the drawing) set from the vicinity of the receiving position of the solid preparation to the vicinity of the delivery position. Then, the solid preparation contained in the pocket in the horizontal orientation is adsorbed by negative pressure and transported.

The formulation printing device 1 includes a first detection device 31 installed near the detection roll 30, and a second detection device installed near the first printing roll 40 ( Installed near the Article 2 exit device (41), the first printing device (Article 1 printing device) (42), the first inspection device (Article 1 printing device) (43), and the second printing roll (50). It is further equipped with a third detection device (Section 3 exit device) (51), a second printing device (Section 2 printing device) (52), and a second inspection device (Section 2 printing device) (53).

The first detection device 31, the second detection device 41, and the third detection device 51 are formed by a detection roll 30, a first printing roll 40, and a second printing roll 50, respectively. When features such as secant lines, recesses, or marks exist on the exposed surface of the conveyed solid preparation, these features are detected. Since the exposed surface of the solid preparation detected by the third detection device 51 is the same side as the exposed surface of the solid preparation detected by the first detection device 31, the third detection device 51 You can also configure it without installation.

The first printing device 42 and the second printing device 52 are based on the characteristics of the solid formulation with respect to the exposed surface of the solid formulation conveyed by the first printing roll 40 and the second printing roll 50. and print. Since the exposed surface of the solid preparation being transported is reversed between the detection roll 30 and the first printing roll 40, even when the features of the solid preparation are partially present, the features are reliably detected and the features are printed. You can print tailored to your needs. For example, if the solid dosage form (F) is a tablet with secant lines on only one side, printing can be done in accordance with the direction of the secant lines on one side where the secant lines are present. Even for the other side, printing can be done according to the printing direction of one side. The printing state of the solid preparation by the first printing device (42) and the second printing device (52) is inspected by the first inspection device (43) and the second inspection device (53).

According to the formulation printing device 1 of the present embodiment, compared to the conventional configuration shown in Fig. 4, feature detection of the solid formulation before printing can be performed without increasing the number of rolls that convey the solid formulation, and the compact configuration allows , angle-aligned printing on both sides of tablets with single-sided secant lines, etc. can be done with high precision. When feature detection of the solid formulation is unnecessary, the solid formulation may be supplied from the conveyance roll 20 to the first printing roll 40 without installing the detection roll 30, thereby further compacting the configuration. can do.
