The lifting frame 41 is, as shown in FIG.
It is formed of a rectangular horizontal frame, and has a size through which the medicine storage basket 2 passes. The two guide rods 39 penetrate the elevating frame 41, and the drive screw 40 penetrates and engages with the elevating frame 41. When the driving screw 40 rotates, the elevating frame 41 moves up and down. .

A pair of movable plates 42 are mounted on the left and right of the lifting frame 41, respectively. On each movable plate 42, two movable claws 45 for supporting the left and right edges 2a of the medicine storage bucket 2 are provided. Installed. A pair of movable plates 42
Between the support position where the movable claw 45 supports the left and right edges 2a of the medicine storage bucket 2 from below, and the retracted position where the movable claw 45 retreats from the left and right edges 2a of the medicine storage bucket 2 , And can slide in the left-right direction along the guide 46. A cam groove 4 of a cam plate 47 provided on the leg portion 12 of the lower body 8 is provided on a side end surface of the pair of movable
A cam pin 49 that fits into the projection 8 is provided.

As shown in FIG. 6, a cam groove 48 of the cam plate 47 has a first cam groove 48a extending in the vertical direction and a second cam groove extending in the vertical direction at a predetermined distance from the first cam groove 48a. 48b and the second cam groove 48a from the first cam groove 48a.
Third cam groove 4 extending obliquely downward toward cam groove 48b
8c. The third cam groove 48c is wider than the first cam groove 48a and the second cam groove 48b. A switching claw 50 is attached to the third cam groove 48c so as to be rotatable by a shaft 51. This switching claw 50
Have both ends of the first cam groove 4 as shown by solid lines.
8a and a second position where both ends abut on the side walls of the third cam groove 48c, as shown by a two-dot chain line. It is possible and biased by a spring (not shown) toward the first position shown by the solid line.

Next, the operation of the medicine storage bucket laminating apparatus having the above configuration will be described.

In FIG. 1, a medicine storage bucket 2 containing medicine packed in a bag is conveyed from a medicine supply device (not shown) on the left side of the main body 3 to a lower main body 8 of the main body 3.
, The motor (not shown) is driven to rotate forward, the drive screw 40 is rotated via the belt 44 and the pulley 43, and the elevating frame 41 is lowered. During the lowering of the lifting frame 41, the cam pins 49 of the movable plate 42 of the lifting frame 41
As shown by an arrow a in FIG. 6, the first cam groove 4 of the cam plate 47 is formed.
8a, moves down along the upper side of the third cam groove 48c to reach the upper end of the second cam groove 48b.
It moves past the second cam groove 48b while rotating past the second position shown by the dashed line. Cam pin 49
Is passed, the switching claw 50 returns to the first position. As described above, when the cam pin 49 moves from the first cam groove 48a to the second cam groove 48b, the left and right movable plates 42 slide in directions away from each other as shown in FIG. Retreats. As a result, the lifting frame 4
1 moves down without the movable claw 45 of the movable plate 42 interfering with the edge 2 a of the medicine storage bucket 2.

The movable pawl 4 of the movable plate 42 of the lifting frame 41
When 5 reaches below the edge 2a of the medicine storage bucket 2, the motor (not shown) is rotated reversely, and the lifting frame 41 is raised. While the elevating frame 41 is being raised, the cam pins 49 of the movable plate 42 of the elevating frame 41 move upward along the second cam grooves 48b of the cam plate 47 as shown by arrows b in FIG. The lower portion of the first cam groove 48a passes through the lower side of the first cam groove 48a, and the switching claw 50 moves upward while rotating the switching claw 50 to the second position along the first cam groove 48a. When the cam pin 49 passes, the switching claw 5
0 returns to the first position. As described above, when the cam pin 49 moves from the second cam groove 48b to the first cam groove 48a, the left and right movable plates 42 slide in a direction approaching each other as shown in FIG. 45 protrudes. As a result, as the lifting frame 41 moves up, the movable claw 42 pushes up the medicine storage bucket 2.

When the edge 2a of the medicine storage bucket 2 kicks up the lower push-up claw 5 and reaches above the push-up claw 5, the motor (not shown) is switched to the normal rotation and lowered to the initial position. . Thereby, the medicine storage bucket 2
The edge 2a is supported by the lowermost push-up claw 5.

When the next medicine storage bucket 2 arrives at the lower body 8 of the main body 3 after being conveyed on the conveyor 13, it is lifted by the lift 7 and supported by the lower push-up claw 5 in the same manner as described above. That is, the previous medicine storage bucket 2 already supported by the lower push-up claw 5 by the previous operation is supported by the lowermost support claw 4 by the operation of the push-up claw 5 described below. .

That is, the motor 37 is driven to drive the drive shaft 3
The rotation shaft 32 is rotated via the pin 5 and the slide plate 6 is raised by one pitch of the push-up claw 5 via the rack and pinions 31 and 33. Thereby, the edge 2a of the medicine storage bucket 2 supported by the lowermost push-up claw 5
Is pushed up. Then, the edge 2a of the medicine storage bucket 2 kicks up and passes through the lowermost support claw 4 and
When the motor 37 reaches the position above the supporting claw 4 of the step, the motor 37 is rotated in the reverse direction, and the slide plate 6 is lowered to the initial position. Thus, the edge 2a of the medicine storage bucket 2 is supported by the lowermost support claw 4.

In this manner, the medicine storage bucket 2 is supported by the upper support claws 4 while being sequentially pushed up by the push-up claws 5, while a new medicine storage bucket 2 is supported by the empty lowest support claw 4. . The drug storage basket 2 is supported by all the supporting claws 4, and the drug storage basket 2 initially supported
Reaches the uppermost stage, the limit switch 17 detects this, terminates the stacking operation of the medicine storage bucket 2, and waits until the medicine bucket 2 is taken out.

Each medicine storage bucket 2 supported by the support claws 4 can be taken out at any position. That is, the medicine storage bucket 2 to be taken out is slightly lifted up and pulled out by utilizing the gap between the upper and lower medicine storage buckets 2, whereby the medicine storage bucket 2 can be easily taken out.

[0028]

As is apparent from the above description, according to the present invention, the medicine storage bucket can be lifted by the lift and sequentially pushed up by the push-up pawls and supported by the support pawls. The medicine storage buckets can be sequentially stacked from below. In addition, since each medicine storage bucket is supported by the supporting claws provided at regular intervals, there is an effect that any medicine storage bucket in the middle can be easily taken out.
