Abstract

PURPOSE:To house a needle at a housing portion through a falling passage by conducting the insertion of the needle, taking off the needle from a syringe by the rotation of a chuck, and then opening the chuck. CONSTITUTION:When a sensor 4 detects that a needle has been inserted, a motor 13 is operated by the control of a controller, and a pulley 11 and a chuck coupling cover 10 are rotated. At this time, a brake is not operated, and a rotary body is rotated together, and a chuck 1 is also rotated. By this rotation, the needle is taken off a syringe after a predetermined time. After a predetermined time, the controller operates a cylinder 28 and brings a brake band 27 into contact with a brake portion 26 and stops the rotary body. Simultaneously, by rotating the motor 13 reversely, the chuck coupling cover 10 along starts reversal, and the chuck 1 descends and is opened gradually. When the needle is opened released from the chuck 1, it falls into a falling passage 20 and is housed in a housing portion 3. After the elapse of a predetermined time, the initial state is made to return, and the furnishing of the next needle is stood by.

Next, the method of use and operation will be described. As shown in FIG. 2, the injection needle N of the injector J is inserted into the chuck 1. At this time, the reinforcing piece 50 is caught in the insertion of the chuck 1. When the sensor 4 detects that the injection needle N is inserted, the motor 13 is operated by the control of the control device to rotate the pulley 11 and the chuck fastening cover 10.
At this time, the brake band 27 is separated from the brake portion 26, the brake is not applied, the rotating body 2 rotates together, and the chuck 1 also rotates. By this rotation, the injection needle N is removed from the syringe J after a predetermined time. After the predetermined time, the control device operates the cylinder 28 to bring the brake band 27 into contact with the brake portion 26 and stop the rotating body 2. At the same time, the motor 13 is rotated in the reverse direction. As a result, only the chuck fastening cover 10 starts reverse rotation, the chuck 1 descends, and the chuck 1 is gradually opened. This state is shown in Figure 3.
Is the state shown in. When the injection needle N is released from the chuck 1, the injection needle N falls in the drop passage 20 and the injection needle N is stored in the storage portion 3. After a lapse of a predetermined time, the control device rotates the motor 13 in the normal direction to raise the chuck 1 and return it to the state of FIG. Then, the brake band 27 is connected to the brake section 26.
After that, the initial state is returned to the state where the next mounting of the injection needle N is awaited.
