2. Description of the Related Art Many tablet feeders are arranged at high density,
As a device for efficiently supplying various types of tablets, the tablet supply unit has a plurality of tablet supply units configured to pay out tablets from a plurality of tablet feeders arranged in the vertical direction to a common guide path extending in the vertical direction. No. 61-37, No. 61-37, discloses a tablet storage and take-out device which receives tablets discharged from the guideway of the hopper by a common hopper and supplies the tablets to the packaging device from the lower end outlet of the hopper.
No. 61 discloses this.

[0003] In the above-mentioned tablet storage and unloading device, the tablet feeding units are arranged in the front-rear and left-right directions, and the tablet feeders are arranged at a high density so as to reduce the size of the device. The upper part of the hopper has a square pyramid shape in order to receive the tablets dispensed from each tablet supply unit.

[0004]

By the way, in the above-mentioned conventional tablet storage and unloading device, when a tablet is dispensed from the tablet supply unit to the outer peripheral portion in the hopper, depending on the type of the tablet, a reaction force at the time of dropping is caused by the type of tablet. In many cases, jumping jumps and whirls in the hopper to the exit.

[0005] This is because the guide path through which the tablets fall is provided straight, the cross section of the inner surface of the hopper is formed obliquely flat, and no measures are taken to control the momentum at which the tablets fall.

For this reason, in the packaging apparatus, the packaging speed needs to be set according to the longest dispensing time of the tablets reaching the outlet of the hopper, and thus there is a problem that packaging takes time.

[0007] This invention solves the above-mentioned conventional problems, shortens the time required for the tablets dispensed to the outer periphery in the hopper to reach the hopper outlet, and improves the packaging speed of the packaging device. Making it a technical issue.

[0008]

In order to solve the above-mentioned problems, in the present invention, a plurality of tablet supply units for feeding tablets to a common guide path extending vertically from each of a plurality of tablet feeders provided vertically. A common hopper below which receives the tablets falling from the lower end of the guide path, the inner surface of the hopper is curved, and the tangent of the curved surface at any point of the vertical section including the center of the hopper is a vertical line. The tablet storage and take-out device is formed so that the angle is formed so as to become larger as it goes below the hopper , and a guide plate extending in the radial direction is provided on the inner surface of the hopper .

[0009]

According to the tablet storage and take-out device of the present invention having the above-described structure, the tablet falling down the guide path and hitting the hopper has a curved inner surface of the hopper, and the inclination of the curved surface becomes larger as going downward. Therefore, even if the tablet hits the inner surface of the hopper at any point, the warpage of the tablet is suppressed by the curved surface, the splash is reduced, and a guide plate is provided on the inner surface of the hopper in the radial direction.
As a result, the spiral movement is also suppressed, and the tablet smoothly moves to the outlet.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the tablet storage and unloading device according to the present invention includes a plurality of tablet supply units 1 and a common hopper 10 provided below each tablet supply unit 1.

The plurality of tablet supply units 1 may be arranged in the front-rear and left-right directions, or may be arranged in the circumferential direction. In the tablet supply unit 1, a plurality of tablet feeders 2 are provided in the vertical direction, and tablets discharged from each tablet feeder 2 are dropped from the common guide path 3 into the hopper 10.

As shown in FIG. 3, the tablet feeder 2 has a conical bottom surface in the tablet case 4 in which tablets are filled, and a plurality of conical outer peripheral surfaces of a rotor 5 provided on the bottom surface. Is formed, and the rotor 5 is connected to the motor 7.
The tablet a which has entered the pocket 6 from inside the tablet case 4 is conveyed in the circumferential direction and discharged from the outlet 8 formed at the bottom of the tablet case 4 to the guide path 3.

Further, in order to prevent the tablets a from being continuously discharged from the outlet 8, a baffle plate 9 is provided above the outlet 8 of the tablet case 4, and the pocket 6 facing the outlet 8 by the baffle plate 9 is provided. Prevents tablets from entering inside.

A sensor (PH) for detecting the passage of tablets a is attached to the passage from the outlet 8 to the guide path 3, and when the sensor (PH) detects a preset number of tablets, the motor 7 stops.

As shown in FIG. 2, a lid 20 is provided at the lower end of the guide path 3. As shown in FIG. This lid 20 is pin 2
It is rotatably supported around 1 and is opened and closed by the operation of the solenoid 22.

Here, the time from the start of operation of the tablet feeder 2 to the time when the tablet a discharged from the tablet feeder 2 is supported by the lid 20 can be known in advance by calculation or actual operation. For this reason, in this embodiment, the solenoid 22 is actuated to open the lid 20 after a certain time after the required number of tablets has been counted by the sensor (PH) that detects the passage of tablets.

The lower end of the guide path 3 is fixed to a horizontal support disk plate 3D.
, A guide hole 3a is provided. The cross-sectional shape of the guide hole 3a is curved, and the curve is formed such that the angle formed by the vertical line intersecting at an arbitrary point and the connection of the curve at that point becomes larger as the lower point becomes.

The hopper 10 is sized to receive tablets discharged from each of the plurality of tablet supply units 1, and a shutter 13 which is opened and closed by a solenoid 12 is provided at an outlet 11 at its lower end. Here, the shutter 13 may be provided as necessary and may be omitted. A guide plate 14 extending radially from the outlet 11 is provided on the inner surface of the hopper 10. The number of guide plates 14 is arbitrary.

The inner surface of the hopper 10 has a curved shape as shown in FIG. 1, and the curved surface has an angle θ between a vertical line intersecting the curved surface at an arbitrary point and the connection of the curved surface at that point. It is formed so as to become larger.

In the apparatus of this embodiment having the above-described structure, a predetermined tablet feeder 2 is operated through the control device, and the tablets are discharged from the tablet feeder 2 at a constant rate.

When the tablet feeder 2 is operated, the lid 20 closes the lower end opening of the guide path 3. Therefore, tablets discharged from the tablet feeder 2 to the guide path 3 fall along the guide path 3 and are supported by the lid 20.

When the tablet a is supported by the lid 20, the solenoid 22 operates to rotate the lid 20 downward. Therefore, the tablets a supported by the lid 20 fall into the hopper 10, slide down along the inner surface of the hopper 10, and are discharged from the outlet 11 at the lower end.

At this time, since the inner surface of the hopper 10 is formed into a curved surface, when the tablet a falls and collides with the inner surface of the hopper, the tablet a Since the contact angle is small, the splash due to the reaction force is small, and useless jump is suppressed.

Further, when the tablets are dispensed from the tablet supply unit 1 into the hopper 10, depending on the type of tablets, the tablets are rebounded by a reaction force at the time of dropping, and the movement of moving to the outlet 11 in a spiral shape is caused by a guide plate. The tablet can be guided to the outlet 11 along the guide plate 14. For this reason, the tablets dispensed into the hopper 10 move smoothly toward the outlet 11 and
1 is supported by the shutter 13 provided.

The tablets at the outlet 11 are discharged downward by opening the shutter 13, and are packaged by a packaging device (not shown).
