In order to achieve the above object, the tablet pick-and-place mechanism of the present invention is provided with a pneumatic circuit device, a cam, and a plurality of pick-and-place devices. The pneumatic circuit device is provided with a rotating shaft, and a surface of the rotating shaft is laterally disposed with a track and is connected to the track. The pick-and-place device is disposed on the outer side of the rotating shaft of the pneumatic circuit device, so that the two pick-and-place devices on the track are respectively located on the two sides of the cam, and the inner wall of the cam forms a first working surface, and the two sides of the cam are formed. Corresponding to the second working surface, when the rotating shaft drives the pick-and-place device to rotate, the second working surface causes relative and reverse displacement movements of the two pick-and-place devices on the track, so that the pick-and-place device changes after sucking the tablet The spacing between the two tablets.

Referring to the first to fifth figures, it can be clearly seen from the figure that the tablet pick-and-place mechanism of the present invention is provided with a pneumatic circuit device 1, a cam 2, and a plurality of pick-and-place devices 3, wherein: the pneumatic circuit device 1 A rotating shaft 11 is disposed, the rotating shaft 11 is connected to the base 12, a vacuum suction port 13 is disposed on one side of the base 12, and a plurality of tracks 111 are laterally disposed on the surface of the rotating shaft 11, and the track 111 is disposed at a circumferential interval, and Two pick-and-place devices 3 are connected to each track 111, and a detecting disk 14 that is rotated with the rotating shaft 11 is connected to one side of the rotating shaft 11, and a scale 141 is disposed on the periphery of the detecting disk 14 and the detecting disk 14 side is A detector 15 is provided. The detector 15 is configured to detect the rotational position of the rotating shaft 11 by detecting the scale 141 of the detecting disk 14.

The cam 2 is provided with a through space 21 penetrating the two side surfaces, and the wearing space 21 is sleeved outside the rotating shaft 11 of the pneumatic circuit device 1 so that the two pick-and-place devices 3 on each track 111 are respectively located on the two sides of the cam 2 The inner wall of the wearing space 21 forms a first working surface 22, and the two side surfaces of the cam 2 are formed with an opposite second working surface 23; the two working sides of the second working surface 23 respectively have a medicine taking section 231 and The medicine section 232, and the guiding section 233 is disposed between the taking section 231 and the medicine section 232, and the distance of the medicine taking section 231 of the second working surface 23 is smaller than the medicine section 232 of the second working surface 23, and The first working surface 22 is recessed with a medicine taking slot 221 and a medicine receiving slot 222. The medicine taking slot 221 is located at the medicine taking section 231 of the second working surface 23, and the medicine tank 222 is located at the second working surface 23. Drug section 232.

The pick-and-place device 3 is provided with a sliding seat 31 connected to the rail 111. The sliding seat 31 has a fixing seat 32 extending on one side thereof, a sliding rail 33 is disposed on the surface of the fixing base 32, and a displacement seat 34 is connected to the sliding rail 33. The displacement seat 34 is provided with a suction cup 35 for sucking and placing a tablet (not shown) on the side away from the sliding seat 31. The suction cup 35 is connected to the vacuum suction port 13, and the displacement seat 34 is adjacent to the sliding seat 31. One side is pivotally connected with a first abutting wheel 36 and a second abutting wheel 37. The first abutting wheel 36 abuts against the first working surface 22, and the second abutting wheel 37 abuts against the second working surface 23; A first elastic member 4 is disposed between the two pick-and-place devices 3 of each of the rails 111. The two ends of the first elastic member 4 are respectively connected to the sliding seats 31 of the second pick-and-place device 3, and are elastically reset by the first elastic member 4. The sliding seat 31 of the second pick-and-place device 3 is moved toward the cam 2 according to the rail 111 to keep the second abutting wheel 37 against the second working surface 23; and the sliding seat 31 and the displacement seat of each pick-and-place device 3 A second elastic member 5 is disposed between the two ends 34, and the two ends of the second elastic member 5 are respectively connected to the sliding seat 31 and the displacement seat 34, by the second bomb The ability of elastic return member 5, driving displacement towards the seat 34 away from the slide base 31 to keep the first wheel 36 abutting the first abutting face 22.

Referring to the first, third, fifth and sixth figures, it can be clearly seen from the figure that when the invention is used, the rotary shaft 11 of the pneumatic circuit device 1 is rotated when rotating When the shaft 11 is rotated, the rails 111 and the pick-and-place device 3 on each of the rails 111 are simultaneously rotated, because the pick-and-place device 3 on the rail 111 is located on both sides of the cam 2, and the elasticity of the first elastic member 4 is utilized. The resetting capability pulls the sliding seat 31 of the pick-and-place device 3, so that the second abutting wheel 37 of the pick-and-place device 3 is held against the second working surface 23, and the taking section 231 of the second working surface 23 of the cam 2 The spacing section 232 of the second working surface 23 is smaller than the second loading surface 23, so that the two pick-and-place devices 3 on the track 111 generate different distances during the rotation; further, due to the sliding seat 31 and the displacement seat 34 of the pick-and-place device 3 A second elastic element 5 is disposed between the second elastic element 5, and the displacement of the displacement seat 34 toward the sliding seat 31 is maintained, and the first abutting wheel 36 is held against the first working surface 22, and The first working surface 22 is recessed with a medicine taking slot 221 and a medicine receiving slot 222, so that the pick-and-place device 3 is in the process of rotation. When the first abutting wheel 36 of the pick-and-place device 3 enters the medicine taking slot 221 or the medicine receiving slot 222, the displacement seat 34 drives the suction cup 35 to extend, and the first resisting wheel 36 passes over the medicine taking slot 221 or the medicine receiving slot. After 222, the displacement seat 34 is caused to drive the suction cup 35 to retract; by the way, when the pick-and-place device 3 rotates with the rotating shaft 11 to the take-up section 231 of the cam 2, the distance between the pick-and-place devices 3 on the same track 111 is the smallest. When the first abutting wheel 36 of the pick-and-place device 3 enters the medicine taking slot 221, the suction cup 35 is extended to abut against the tablet. At this time, the vacuum suction port 13 starts to pump air, and the suction cup 35 is negative. The tablet is sucked up, and the tablet is pulled back when the first abutting wheel 36 passes over the medicine taking slot 221, and when the picking and placing device 3 is rotated to the medicine section 232 of the cam 2, the pick-and-place device 3 on the same track 111 The spacing is expanded to a suitable distance (such as the distance between the package bags), and when the first abutting wheel 36 of the pick-and-place device 3 enters the medicine receiving slot 222, the suction cup 35 is extended, and the vacuum suction port 13 is The pumping is stopped, and the suction cup 35 is vacuumed to place the tablet. It can be seen that the pick-and-place device 3 takes the same track 111 when sucking and placing the tablet. The spacing of the devices 3 is different, so that when the tablets are sucked, the distance between the two pick-and-place devices 3 is reduced, which can effectively reduce the waste of the tablets during cutting and separating, and when the tablets are placed, the distance between the two pick-and-place devices 3 can be expanded to The distance between the packages is required. Therefore, in addition to reducing the waste of tablet cutting, the present invention only needs to replace the cam 2 if there are different package sizes.
