DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment will be described in detail below with reference to the accompanying drawings.

Embodiment 1 FIG. 1 is a partially cutaway side view of a tablet deburring device according to an embodiment of the present invention, and FIG. 2 is a perspective view for explaining the drive of a tilt drum 5. FIG. 3 is a side view in which the hood 8 is attached to the deburring device of this tablet.

A tablet deburring apparatus according to an embodiment of the present invention comprises a cylindrical tilt drum 5, a motor 6 for rotating the tilt drum 5 at a constant speed, and a support base. .

As shown in FIG. 1, the inclined drum 5 has a cylindrical shape and is formed of a strong steel material having high rigidity and abrasion resistance so as to withstand repeated use and to roll the tablet. , Its inner wall surface is processed to reduce friction. The inclined drum 5 has a charging port 1 for charging a tablet on one flat side surface and a discharging port 2 for discharging a tablet on the other flat side surface. Further, the curved side surface 3 of the inclined drum 5 is provided with a plurality of opening holes 4 for removing burrs. The shape of the opening 4 is not limited to the round shape as shown in the figure, but may be a square or a slit.

On the inner wall of the inclined drum 5, there is a baffle plate 7 which projects from the inner wall. The protruding height of the baffle plate 7 can be changed depending on the size of the tablet to be charged, and it is preferable that the height is 1 to 2 times the size of the tablet.

The motor 6 is connected by an O-ring as shown in FIG. 1 in order to rotate the tilt drum 5, and the rotational speed can be varied. The transmission of the power of the motor 6 is not particularly limited, and a wheel is inserted into the rotation shaft of the motor 6 as shown in FIG. What you do, other,
It may be a combination of gears.

The support base supports the tilting drum 5 and the motor 6, and can support the tilting drum 5 at a constant angle of 2 to 15 °. A bearing is mounted between the tilt drum 5 and this support to facilitate rotation of the tilt drum 5. This bearing is preferably a dustproof type or dry metal type bearing.

FIG. 3 shows a hood 8 for covering the inclined drum 5.
The hood 8 has an exhaust port 9 for exhausting air from the lower part, and the hood 8 can be sucked from the exhaust port 9. Further, an air blow device 10 is attached to the hood 8 located around the discharge port 2 so that air can be blown from the discharge port 2 of the tilt drum 5 toward the inside of the tilt drum 5.

The method of using the deburring device for the tablet will be described below with a diameter of 10 mm and a length of 15 mm as shown in FIG.
As an example of the method for deburring tablets from
Will be described with reference to.

First, 200 tablets / minute of the above tablets are charged from the charging port 1 of the inclined drum 5 rotating at 20 rpm. The amount of tablet to be charged varies depending on the size and material of the tablet, but if the diameter is 20 mm or less and the length / diameter is 1 to 3, 100 to 25 per minute
0 is preferable. The rotation speed of the motor 6 also varies depending on the size and material of the tablet and the amount charged, but is preferably 5 to 40 rpm.

The tablet loaded on the inclined drum 5 is
When the tilting drum 5 rotates, it rolls and makes contact with each other,
The burr is removed by colliding with the inner wall,
It moves to the discharge port 2 due to the inclination of 0 °.

However, since the baffle plate 7 is installed on the inner wall of the inclined drum 5, the tablet stays on the baffle plate 7 to improve the effect of removing burrs. The baffle plates 7 are installed at two places on the tilt drum 5, but the number varies depending on the length of the tilt drum 5 and the material to be charged, and the time during which the tablet stays on the tilt drum 5 can be adjusted. it can.

Further, when the moved tablet comes to the front of the discharge port 2 of the inclined drum 5, the air blower 1
With 0, air is blown from the top, bottom, left and right. The air blows off burrs adhering to the surface of the tablet and the inner wall of the inclined drum 5. The position and number of the air blower 10 to be attached are not particularly limited, but it is preferable that air is uniformly applied to the tablet.

The burr thus removed from the tablet passes through the opening hole 4 formed in the lower inclined drum 5. The burr that has passed through the opening 4 is
Since the inclined drum 5 is covered with the hood 8 as shown in FIG. 5, it falls onto the hood 8 and is sucked from the exhaust port 9 provided at the lower part of the hood 8 to collect dust.

The tablet from which the burr has been removed is discharged from the discharge port 2. The time for this tablet to pass through the inclined drum 5 was about 20 seconds. This time depends on the size and material of the tablet,
0 to 30 seconds is preferable.

[0028]

According to the tablet deburring apparatus of the present invention, the burr generated on the tablet can be removed by moving in the rotating inclined drum 5, so that the burr can be continuously removed. . Further, it is possible to reliably remove material burrs generated on the tablet and collect dust without adhering to the tablet.
