Abstract

PURPOSE:To prevent an axial component from taking anomalous attitudes and also cause a supporting piece for preventing oscillation of the component to retreat while the component passes for permitting the passage, by providing a retreat mechanism for the supporting piece. CONSTITUTION:When a component 1 is approaching the assembly, a supporting piece 16 is caused to locate in its waiting position by the action of an air cylinder 13. When the component 1 has actually approached the assembly, it is received at its head 3 by a stopper piece 10, and at its portion 2 by the supporting piece 16 simultaneously, so that the component 1 may not tilt to one side, the head 3 being stuck to the end face of a supply rod 6. When the supply rod 6 advances, the air cylinder 13 forces the supporting piece 16 to retreat, thereby permitting the advance of the supply rod 6 and/or that of the component 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a device for supporting shaft-shaped parts such as the shaft of a rotating body or a projection bolt in the correct posture. Emphasis is placed on correctly determining the initial posture before moving. (b) Conventional technology I can't find any prior art that corresponds to the present invention in the 1-distortion running range, or 1. Figure 7 shows the case where no consideration is given.
(hereinafter simply referred to as part) 1 is something like a bolt consisting of a shaft part 2 and a head 5.

A guide tube 5 that descends along the slope in a hanging state from the chute 4 is welded to the chute 4, and a rod 6 is slidably inserted through the guide tube 5. ~
Rod 6 is given the function of holding part 1,
There are various ways to do this, such as holding it with a chuck mechanism or holding it by holding it with a plate, but here we show a case where a magnet (Mizukuta stone) is used. , the soap supplying rod 6 consists of a hollow shaft 7 and an inner shaft 8 slidably fitted into the hollow shaft 7.
A magnet 9 is fixed to the tip. A stopper piece 10 protrudes from the hollow shaft 7 to prevent the component 1 from entering, and the end surfaces of the hollow shaft 7, the inner shaft 8, and the magnet 9 form one plane.

Here, the head 5t is brought into close contact with suction. now.

When the supply rod 6 advances to a predetermined position with the head 3 or the tip of the supply rod 6 in close contact with the hollow shaft 7 and the inner shaft 8, the supply rod 6 is stopped and only the inner shaft 8 is forced. When the magnet 9 is moved away from the head 6 by moving backward, the attractive magnetic force of the part 1 gradually disappears, so the part 1 falls and is supplied to the target location.

(c) Problems to be Solved by the Invention Part 1 in FIG.
Since it is stopped at 0, the shaft part 2 moves several centimeters counterclockwise due to inertia.
As shown in the figure, the feed rod 6 moves in the advancing direction (arrow 11
), or if the part 1 is held at an angle, or if the case is severe, the part 1 will fall down and get destroyed. If the supply rod 6 advances in the holding position as shown in the figure, the parts may fall off during the process, and an unnatural collision may occur with the opposing member.

) Problem t - Means for solving the problem and its operation The present invention has the following features:
t41 provided to solve the above-mentioned problems.
Therefore, when supplying the shaft-like part to the target location with the entire shaft-like part held at the tip of the image rod, the shaft-like part is placed at a location away from the point of contact between the tip of the supply rod and the shaft-like part. A supporting piece is provided from the stationary member side to prevent the swinging of the part, and a retraction mechanism for the supporting piece is provided, and the supporting piece prevents the part from taking an abnormal posture,
When the supply rod advances, the support piece retracts to allow parts and the supply rod to pass. (E) Example In the following examples, only the differences from the configuration shown in Fig. 7 will be explained. . An arm member 12 is welded to the guide tube 5, and an air cylinder 13 is attached to the arm member 12 via a support stay 14. The piston rod 151 of the air cylinder 13 is fixed to the support piece 16, which closely matches the cross-sectional shape of the shaft portion 2 as shown in the second example. In addition, instead of the air cylinder 13, use a power source like an electric solenoid! 111] device may be used. Therefore, the support piece 16 is attached to the arm member 12, which is a stationary member.

When the component 1 enters the IC, the support piece 16 is held in the position shown in FIG. 1 by the action of the air cylinder 13. Therefore, the part 1 does not support the part 2 at the same time as the head 6 is received by the stopper piece 10, and the head 3 may not be supported at the same time as the first decoy. The end surface of the tube 6 will be in close contact with the end surface.And then,
When advancing 6 rods, use air cylinder 1.
3, the support piece 16 is retracted, allowing the supply rod 6 and the component 1 to advance.

FIG. 3 shows an example of a retraction mechanism for the support piece 16, in which the support piece 16 is fixed to one end of a swing arm 18 attached to a pivot shaft 17, and the other end is fixed to a piston rod 20 of an air cylinder 19. The support piece 16 is holding @s2 in the state shown in the same figure.

When the swing arm 18 is rotated by the air cylinder 191, the support piece 16 is retracted.

As shown in FIG. 4, the magnet 9 is replaced by an electromechanical type, and the supply rod 6 passes through the excitation coil 21.

5 and 6 show the opening/closing plate 22 for temporarily locking the part 1,
23, the pivots 26 and 27k are fixed to the fixed plates 24 and 25 attached to the side of the guide tube 5, and the opening and closing plates 22 and 23 are opened and closed by these two shafts. A force in the closing direction is applied to the opening/closing plates 22, 23 by the helical springs attached to the opening/closing plates 26, 27, so that the component 1 is supported from both sides by its head 6 or the opening/closing plates. When the supply rod 6 advances, the head 6 is supplied without pushing open/close plates 22 and 23 left and right while being attracted.

Even in the case of the type using the opening/closing plate as described above, if the arm member 12 similar to the above-mentioned one shown by the two-dot chain line is welded to form the support piece and evacuation mechanism similar to that shown in FIG. According to the present invention, since the supporting piece for the shaft of the component is provided at a location remote from the contact point between the tip of the supply rod and the shaft-shaped component, Since the parts are simultaneously received at at least 2a positions, the above-mentioned initial posture can be determined correctly without causing the parts to swing due to inertia.Furthermore, since the support piece is equipped with an evacuation mechanism, the supply rod There will be no hindrance to the expansion of products and parts.
