に終わつていた。(B) Prior art Compression coil springs can be installed in various ways, such as being placed outside the shaft or inserted into a hole, but in the case of small springs, both ends are simply attached to opposing spring holders. Engaging is also often used. The spring receiving portion may be a protrusion that enters into the coil portion of the spring or a recessed portion that receives the spring, but in any case, when engaging a compression coil spring here, the spring must be compressed once. However, as is well known, if the length of the spring is relatively large compared to the diameter, the spring will not compress naturally and will curve to the side. This is a very unstable state of holding, and it is easy to fall off, and there is also a great risk that it will come out in an undesired direction when you try to release the compression and engage it with the spring receiver. Because of this difficulty in handling, attempts to install compression coil springs using robotic hands have only resulted in a high failure rate of installation.

A guide slope narrowing the outlet is provided on the inner wall of the holder, and the spring is compressed at the outlet to be smaller than the spacing between the spring receivers. In addition, the front surface of the pusher has a concave shape in the center, so that it continues to maintain a concave posture with respect to the forward direction of the spring being pushed out, and when it escapes from the holder, it escapes from both ends first and enters the spring receiver. This ensures reliable engagement.

トアームの先端に装着して使用する。(e) Example In the figure, 1 is a cylindrical holder with a rectangular cross section. The holding body 1 is divided into two parts by a plane parallel to its axis, one being a fixed jaw 2 and the other being a movable jaw 3 that moves relative to the fixed jaw 2 while maintaining a parallel relationship to produce an opening/closing operation. It is becoming. 4 is a pusher that is slidably provided in the axial direction at the joint between the jaws 2 and 3, and the tip is the third
As seen in the figure, it has a flat plate shape, and an arc-shaped depression 5 is provided on the front surface of the plate. Reference numeral 6 denotes a backing plate integrated with the fixed jaw 2 by a stay 7, which passes through a window 8 on the side of the movable jaw 3 and forms a series of barriers in line with the front surface of the pusher 4 in its most retracted state. Therefore, the outlet 9 of the holding body 1
Opposite guide slopes 10 and 11 are formed on the inner wall of the holder. The guide slope 10 is provided on the fixed jaw 2, and the guide slope 11 is provided on the movable jaw 3 symmetrically to each other, and the width of the outlet 9 is narrowed from the inside to the outside of the holder 1. Furthermore, the guide slope 10,
Cutting portions 12 and 13 are formed in the center of the pusher 11 to allow both side edges of the pusher 4 to pass through. Movable Jiyo 3
The pusher 4 and the pusher 4 are driven by an air cylinder (not shown), and a unit including these is mounted on the tip of a robot arm.

部18,19に係合するものである。 Next, the operation of the present apparatus will be explained based on the figures from FIG. 4 onwards. In FIG. 4, the fixed jaw 2 and the movable jaw 3 are in an open state and are facing the spring supply section 14. In the states shown in FIGS. 4 to 6, the holder 1 maintains a posture with its axis horizontal, and the figures are shown as cross-sectional views seen from the top. The spring supply section 14 has a cylindrical shape with an outlet facing the holder 1, and has a pusher 15 inside and a spring receiving port 16 on the side. FIG. 4 shows one compression coil spring 17 inserted through the spring receiving port 16. At this time spring 1
7 is in a position perpendicular to the axis of the holding body 1. Next, as shown in FIG. 5, the pusher 15 moves forward and forces the spring 17 between the jaws 2 and 3. The spring 17 is blocked by the pusher 4 and the backing plate 6 and does not go any deeper, but in this state, the spring 1
A portion of the end portion of the guide 7 rides on the guide slopes 10 and 11. Next, as shown in Figure 6, pusher 15
When the movable jaw 3 is retracted and the movable jaw 3 is closed, the spring 17
is compressed. At this time, since both ends of the spring 17 hang on the guide slopes 10 and 11 as described above, the spring 17 is bent toward the pusher 4 and held in a curved shape along the recess 5. After this, the holding body 1 changes its direction, and as shown in FIG.
approach. The spring receiving parts 18 and 19 are constituted by opposing protrusions, and the distance between their tips is slightly wider than the width of the outlet 9 (the point where the guide slopes 10 and 11 are closest). When the pusher 4 is moved forward, the spring 17 slides on the guide slopes 10 and 11 while maintaining its concavely curved shape in the forward direction, and is pushed out from both ends first to form the spring receivers 18 and 19 as shown in FIG. It is something that engages with.

る。(F) Effects of the Invention The present invention utilizes the property of a compression coil spring that tends to curve when compressed, and uses a pusher with a concave front surface and a guide slope on the inner wall of the holder to create a shape that curves concavely in the forward direction. hold the spring in
Since the spring is pushed out as it is, the spring always leaves the holder from both ends that should be engaged with the spring receivers, and if the spring receivers are placed just outside, the springs will surely engage. That is, a compression coil spring assembly device having high reliability can be obtained.
