Abstract
The stopper device 10 includes a body 11 and a cylindrical rotating member 21 accommodated in the body 11. The rotating member 21 is rotated by the motor 18. The rod 31 is accommodated in the rotating member 21. In addition, a pair of cam grooves 32 are formed on the circumferential surface of the rod 31. The rotating member 21 has a pair of cam followers 24 which are engaged with the pair of cam grooves 32 and guided along the cam groove 32, respectively. Each cam follower 24 is provided so that it may protrude toward the centerline axis of the rotating member 21. As shown in FIG. As the rotary member 21 is rotated, each cam follower 24 is guided along the corresponding cam groove 32 so that the rod 31 is linearly moved in the rotary member 21.
Description
The present invention relates to a stopper device for stopping a work at a predetermined position.
In a production facility using a conveyor, predetermined work is performed by stopping the workpiece moving on the conveyor at a predetermined position once. After the end of work, the workpiece is moved again along the conveyor. And a stopper apparatus is widely used for stopping a workpiece to a predetermined position once.
The stopper device has a cylindrical body and a rod which linearly moves in the body in a state in which rotation is restricted with respect to the body. The rod has a built-in shock absorber. A stopper lever for interlocking with the shock absorber and stopping the work at a predetermined position is provided at the tip of the rod. The stopper lever can be linearly integrated with the rod.
When the workpiece conveyed on the conveyor is once stopped at a predetermined position, the stopper lever is linearly moved by linearly moving the rod to protrude from the body. As a result, the work abuts against the stopper lever, and the conveyance of the work is restrained. At this time, the shock to the workpiece conveyed on the conveyor by the shock absorber is buffered.
By the way, there exists an actuator of Unexamined-Japanese-Patent No. 3-8827 as a mechanism which linearly moves a rod using the rotational motion of a motor. In the actuator of this publication, the feed screw shaft is inserted into the cylindrical operating shaft, and the operating shaft and the feed screw shaft are screwed through the ball screw. In addition, the rotary shaft of the motor and the feed screw shaft are connected via a gear. When the rotating shaft of the electric motor rotates, the feed screw shaft rotates through the gear. By the rotational movement of the feed screw shaft, the ball screw is moved forward or backward with respect to the feed screw shaft so that the operating shaft moves linearly. As a result, the driven part attached to the front-end | tip of an operation shaft is made to move linearly.
However, in the actuator of the above publication, a cylindrical operation shaft is provided outside the feed screw shaft in order to linearly move the operation shaft. For this reason, the operating shaft should secure at least the length along the linear travel distance of the operating shaft. In addition, since the driven portion is mounted at the tip of the operation shaft, there is a problem that the length of the actuator in the axial direction of the operation shaft is enlarged.
An object of the present invention is to provide a stopper device capable of linearly moving a rod by using a rotational motion of the motor without increasing the size.
According to one aspect of the present invention for achieving the above object, a stopper device is provided. The stopper device is a cylindrical body, a rod formed in a retractable manner with respect to the body, a rod having at least one cam groove on a circumferential surface thereof, being supported rotatably on the tip of the rod, and stopping the work. A stopper portion for being incorporated into the tip of the rod, and a shock absorbing mechanism for alleviating the impact of stopping the work by the stopper portion, which is accommodated in the body and rotated by a motor, and the rod is retractably received. And a at least one cam follower installed to protrude toward the center axis of the rotating member from a position opposite to the circumferential surface of the rod in the rotating member, and at least one cam follower engaged with the cam groove. The rod is guided by the cam follower along the cam groove as the member rotates. It is moved linearly in the rotating member.
