For example, there is a component selection device that uses a chute to sort electronic components and other parts that are continuously sent and selects and stores them in multiple storage boxes, and a component selection device that selects components that are held by chucks in multiple holes in a jig. Many automatic component insertion devices that use a motor or cylinder to control the position of a chute or chuck are used. That is, as shown in FIG.
When controlling the movement to the four positions C and D, if the operating member 1 is moved by a motor, it will take a long time to move from point A to point D, resulting in poor workability.
Also, one cylinder can move the operating member 1 to A, B, C,
If you want to stop at the 4 positions of point D, the cylinder must have at least the length between A and D as a stroke, which has the drawback of having to increase the length and space of the cylinder, and moreover, it requires complicated intermediate stops. requires a switching mechanism.

We propose the following parallel composite cylinder. This parallel composite cylinder is made by connecting a plurality of both rod type cylinders, which will be described later, in parallel. For convenience of explaining the principle of the present invention, first, a series composite cylinder, which is the premise of the present invention, will be described since it is necessary to compare with the technology prior to the present invention.

In order to move the aforementioned operating member 1 to the four positions A, B, C, and D, as shown in Figs. It is clear that a cylinder can be used. That is, the closed end surfaces of the two cylinders 2 and 3 are butted against each other and connected, the leading end of the rod 4 of one cylinder 2 is fixed, and the leading end of the rod 5 of the other cylinder 3 is set as the operating end, and the cylinder is operated. Attach member 1. Considering the state shown in FIG. 2 in which the rods 4 and 5 are respectively retracted into the cylinders 2 and 3, the operating end of the rod 5 is defined as point A. Next, consider the case where the piston 6 of one short cylinder 2 is moved to the other end of the cylinder 2 using pneumatic or hydraulic pressure, and the rod 4 is extended from the cylinder 2. Then, since the tip of the rod 4 is fixed, the rod 4 remains stationary, and the cylinders 2 and 3, which are integrally connected, move. Then, when the piston 6 moves through the maximum stroke within the cylinder 2, the movement of each cylinder 2 and 3 stops, and at this time, as shown in FIG. do.
Also, if we return to the state shown in Figure 2 and operate only the long cylinder 3 while leaving the short cylinder 2 as it is, the piston 7 of the cylinder 3 will move to the other end,
Correspondingly, the rod 5 is extended from the cylinder 3, and when the piston 7 has moved to its maximum stroke, the rod 5 stops. Rod 5 at this time
As shown in Figure 4, the position of the operating tip of C
Point. Also, if both cylinders 2 and 3 are operated simultaneously in the state shown in Fig. 2, or the long cylinder 3 is operated in the state shown in Fig. 3, or the short cylinder 2 is operated in the state shown in Fig. The working end of the rod 5 is the maximum extension distance, and this position is designated as point D.

Now, the above-mentioned series composite cylinder has the following problems. First, the accuracy of the stopping position of the operating end of rod 5 at points A, B, C, and D depends on the accuracy of each cylinder 2 and 3, so if the accuracy of cylinders 2 and 3 is different, it is not always possible to stop at each point accurately. It is not always possible to stop, and there is a lack of accuracy.

Next, since the two cylinders 2 and 3 are connected in series, the overall length of the composite cylinder increases, and the installation space becomes unnecessarily long. In addition, especially in the state shown in FIG.
Since the structure supports the rod at one point, its mechanical strength is weak, so if a load is actually applied to the moving end of the rod 5, at least the longer rod 5 may swing or the entire rod may bend, which could be fatal. accidents occur.
Also, the area of both sides of the pistons 6, 7 in each cylinder 2, 3 differs depending on the presence or absence of the rods 4, 5.
Therefore, the strength of the force applied to move the rods 4, 5 is different when extending them from the cylinders 2, 3 and when retracting them, so the reciprocating speed of each rod 4, 5 is different. A,
This results in a disadvantage that the movement speeds of the rod 5 at the operating end between points B, C, and D are not equal. The present invention proposes a parallel composite cylinder in order to solve the problems of the above-mentioned series composite cylinder. Embodiments of the present invention will be described below with reference to the drawings.

For example, 4 cylinders A, B, C, D with 2 cylinders.
As an example of positional movement, the first and second cylinders 8 and 9 of both rods are connected in parallel, as shown in FIGS. 6 to 9. That is, a rod 10 that is sufficiently longer than the first cylinder 8 is passed through one first cylinder 8, and one end of the rod 10 is fixed to the outside as a fixed end 10a, and the other end is a free end 10b. It is as follows. A piston 11 is fixed at a predetermined position approximately in the center of the rod 10, and this piston 11 moves within the first cylinder 8. In addition, stoppers 12a and 12b such as nuts are attached to the lead-out portion of the rod 10, which is always outside the first cylinder 8, so that their positions can be adjusted freely. The cylinder 8 is positioned by each of the stoppers 12a, 12b. Similarly to the first cylinder 8, a rod 13 is passed through the second cylinder 9, and one end of the rod 13 is used as a free end 13a, and the other end is used as an operating end 13b. Further, a piston 14 is fixed approximately at the center of the rod 13, and stoppers 15a and 15b whose positions are freely adjustable are attached to both ends, respectively. Incidentally, each cylinder 8, 9 is mounted on a support base 16 that slides along the axial direction thereof, and maintains a stable posture.

Next, the operation of the parallel composite cylinder will be explained.
First, when moving the operating end 13b to the position of point A, air (or oil) is sent from the air supply port (or oil supply port) 17a at the left end of the first cylinder 8, as shown in FIG. Then, the first cylinder 8 becomes the rod 10
Since it is fixed, it moves to the left on the rod 10 and stops when it hits the stopper 12a. Further, the second cylinder 8 also moves to the left together with the first cylinder 8. At the same time, air (or oil) is sent to the air supply port (or oil supply port) 18b at the right end of the second cylinder 9. Then, in parallel with the movement of the second cylinder 9 by the first cylinder 8, the rod 13 moves to the left with respect to the second cylinder 9, and stops when the stopper 15b hits the second cylinder 9. At this time, the operating end 13b of the rod 13 is at the position A as shown in FIG.

In addition, when moving the operating end 13b from point A to point C, as shown in FIG. Air (or oil) is sent to extend the rod 13 to the right in the drawing and stop it at the position where the stopper 15a hits the second cylinder 9. Then, the rod 13 moves and moves to the operating end 1.
3b comes to point c. In addition, when moving the operating end 13b from point A to point D, switch the air supply ports (or oil supply) to each cylinder 8 and 9 in the state shown in FIG. Then, the rod 13 is moved to the right to the second cylinder 9 until the stopper 15a touches the second cylinder 9 (see FIG. 9).
