Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device that reliably feeds and takes out tablets, capsules, etc. one by one.

Conventional rotary disk-type feeding devices have a cutout on the outer periphery of the rotary disk into which tablets, etc. can be inserted, or round holes are provided so that the tablets, etc. fit into these one by one. It was possible to take out single tablets etc. by rotation, count them and pack them into bottles or bags, or take out single tablets continuously and strip wrap them or print them.

However, although the tablets are inserted flat into round holes or notches in the rotary disk, there are cases where the tablets can be inserted while standing or may not be completely heated.

Measures to solve this problem include slowing down the rotation of the rotary disk to allow more room for the tablets to fall under their own weight, and flattening standing tablets by brushing them. It was not possible to reliably feed and remove the material continuously.

This invention solves these problems, and by using the feeding device of this invention, it can be used not only for continuous packaging but also for counting and filling packaging and counting tablets for product weight percent nicking in product management. It can be used as a quick and reliable method.

Next, an embodiment of the structure of the present invention shown in the drawings will be described as follows.

The rotary disk 1, which rotates at an angle, is rotated by a rotary drive transmission device, that is, a motor 2, a belt 3, a pulley 4, a worm shaft 5, a worm 6, a worm gear 7, and a rotary shaft 8.

The inclination of the rotary disk 1 can be adjusted by loosening the angle fixing plate 10 fixed to the bearing 9 of the rotary shaft 8 by loosening the angle bolt 12 fastened to the support column 11. It can be changed by rotating along the hole 13.

On the outer peripheral edge of the rotary disk 1 are provided protrusions 15 that protrude upward and outward at equal intervals with intervals slightly larger than the diameter of the tablets 14.

The protrusion 15 can be provided only on a part of the entire circumference of the outer peripheral edge, if necessary.

A tablet inlet 16 is arranged above the rotary disk 1, and the lower end of the tablet inlet 16 has a space slightly larger than the height of the tablet 14 from the upper surface of the rotary disk 1. A shield plate 20 is provided in a brim shape.

Outside the outer periphery of the rotary disk 1, there is a tablet bone 19 consisting of a tablet sliding surface 11 having an upper surface slightly lower than the upper surface of the rotary disk 1 and a wall 18 standing up on the outer peripheral edge of the sliding surface 17. It is located.

In the drawing, 26 is a stirring plate attached to a part of the upper surface of the rotary disk 1, and 21 is a stirring plate for packing the tablets 14 that are kicked by the protrusion 15 and ejected from the tablet bone 19 into a bottle or bag. The provided chute, the chute t-21, may be a cylindrical or mouth-shaped chute, etc.
2 is a discharge chute for discharging the tablet 14 by reversing the rotary disk 1; 23 is a phototube hole provided in the sliding surface 17 of the tablet rib 19; 24 is a light emitting phototube disposed above the hole; 25 is a The light receiving tube is shown below.

In operation, when the motor 2 is driven, the rotary disk 1 is rotated by the rotational drive transmission device.

When the tablets 14 are put into the tablet slot 16, there are flat tablets and upright tablets, so the stirring plate 26 attached to the top of the rotary plate 1 stirs the tablets 14 into the upright tablets. The tablet is flattened and then leveled by a tablet leveling plate 20 between the lower surface of the tablet leveling plate 20 and the upper surface of the rotary disk 1 and slid down in the lower direction.

And the tablet 14 that was flattened downward and slid down.
The tablet bones 19 enter the tablet bones 19 one by one from between the protrusions 150 provided at equal intervals, and the width of the tablet bones 190 is slightly smaller than the diameter of the tablet 14, that is, the width between the wall 18 of the tablet bones 19 and the outer peripheral end of the rotary disk 1. The tablet 14 is supported by the sliding surface 11, the wall 18, and the outer periphery of the rotary disk 1, which are provided at a slightly higher position than the sliding surface 17. 18, and as the rotary disk rotates ten times, it is kicked by the protrusion 15 and moves upward on the sliding surface 17.

A phototube hole 23 is provided on the sliding surface 17 near the end of the tablet rib 19, and a light emitting phototube 24 is disposed above the phototube 24, and a light receiving tube 25 is disposed below the hole 23, so that the tablet
Each time a tablet 14 passes through the hole 23, it is confirmed that the tablets 14 are being fed and taken out one by one by blocking light and then counted.

The tablet 14 that has passed through the phototube hole 23 is transferred to the chute 2
Fall into 1.

In this case, in order for the tablet 14 to fall reliably into the chute 21, the tablet 14 must be placed on its sliding surface 17 so that it leans closer to the wall 18 of the tablet rib 19 than to the outer periphery of the rotary disk 1. The top surface must be lower than the top surface of the rotary disk 1.

; The inclination angle of the rotary disk 1 is generally around 15 degrees, but it can be adjusted to suit the tablet.

As explained above, according to the feeding device of the present invention,
When a tablet, etc. is flattened by a leveling plate, it is supported by the sliding surface of the tablet bone between the protrusions, the wall, and the outer periphery of the rotary disk, and is moved in a high direction while being kicked by the protrusions. Because of this, tablets, etc. can be fed smoothly without being damaged, and one by one can be fed quickly and reliably.

Therefore, according to this feeding device, it is possible to continuously strip-pack tablets, etc., to continuously bottle or bag tablets, and to automatically measure the weight.
