Description

[Detailed description of the invention] The present invention is a method for once receiving a rod-shaped part sent by a chute or the like into a delivery device, and then inverting the device by about 90 degrees to fit the part into another member. Regarding parts delivery equipment,
The delivery of parts from the chute to the delivery device and the fitting of parts from the delivery device to other parts can be carried out extremely easily and reliably, and the dimensional accuracy of the hole for clamping the parts in the delivery device against the parts is not required. First, it is an object of the present invention to provide a parts delivery device in which the main body of the device can be manufactured easily.

Conventionally, in this type of device, as shown in FIG. 3 is arranged to correspond to the opening 4 of No. 3. Also, the abbreviation of the delivery device 1
As shown in FIG. 2, another receiving member 5 is disposed on the axis reversed by 90 degrees, and a hole 6 corresponding to the fitting groove 2 is bored in this member 5. With this configuration, the component m is received into the delivery device 1 from the chute 3, and then, after the device is reversed by 90 degrees, the device 1 is moved to the receiving member 5 side, and the component is inserted into the hole 6 of the member 5. It is configured to be inserted.

In the conventional device having the above configuration, as shown in FIG _. If the amount of protrusion from the fitting groove 3 is l ₂ , the amount α of the protrusion of the component m from the fitting groove 3 is α=(D−d)×l ₂ /l ₁ (1). Also, the diameter of the hole 6 of the receiving member 5 of the part m
The amount of protrusion β with respect to d' (≈d) is β=(D-d)×l ₂ /l ₁ +D-d′/2 (2). Therefore, in order to press-fit the part m into the hole 6, either chamfer 5A enough to cover the outer circumferential position of the tip 2A of the part m in the hole 6 of the receiving member 5, or However, it is not always possible to chamfer the component m or the receiving member 5 due to functional or other reasons. Therefore, in order to reduce the amount of protrusion shown in equation (2) above, it is necessary to reduce D-d and D-d' or to make _l2 smaller than _l1 . However, as shown in FIG. 4, the shape of the part m has a bulge 7 with an outer diameter of d ₂ on a part of its outer periphery, and this outer diameter dimension d ₂ is, for example, when the part m is subjected to header processing. If the dimensional accuracy is not higher than that of _{part d1} , which is molded by This means that the transfer device 1A has no choice but to support it. However, as is clear from the figure, reducing l ₂ in order to reduce the amount of protrusion of the tip of component m is constrained by the shape of component m itself, and the degree of freedom is limited. Therefore, the device 1
It is necessary to make the inner diameter D ₂ of A smaller to reduce the deflection of the tip of part m. However, shoot 8
Since the inner diameter _D1 is larger than the bulge diameter _d2 of the part m, it is very difficult to transfer the part m from the chute 8 to the delivery device 1A, and therefore a large chamfer must be made at the entrance of the hole in the device 1A. As a result, l' ₁ becomes smaller and smaller, the amount of protrusion of the tip becomes larger, and it becomes very difficult to press fit into the receiving member 5.

In view of the above points, the present invention has the configuration described in the claims for utility model registration, thereby making it extremely easy to transfer parts from a chute to a delivery device and to insert and press fit parts from the delivery device into other parts. To provide a parts delivery device which can be easily and reliably carried out, does not require much dimensional accuracy of a hole for clamping the parts of the delivery device, and can thereby easily manufacture the device body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the parts delivery device of the present invention will be explained below based on the embodiment shown in the drawings.

As the principle of the parts delivery device of the present invention is shown in the basic structure of FIGS. 6 and 7, the delivery device 10 is composed of two plate-shaped members 11 and 12. 12 are rotatably opposed to each other by pivoting the lower end of the other member 12 to a flange 13 formed at the lower end of one member 11 via a first shaft 27. Further, as described above, the opposing members 11 and 12 are urged to rotate in the closing direction by the springs 14 that are fixed to the upper ends of each member. Further, grooves 15 and 16 having a triangular cross section are formed perpendicularly from the upper ends of the members 11 and 12 on their opposing surfaces, and when the members 11 and 12 are closed, the grooves 15 and 16
5 and 16 are selected to have a size such that a hole 17 is formed between the members 11 and 12 to pinch the component M.

The grooves 15 and 16 have appropriate depths,
A bottom portion 18 for receiving the component M is formed at its lower end.

FIG. 5 shows a concrete delivery device 10 as a first embodiment based on the above-mentioned basic structure, and the same reference numerals as in FIGS. 6 and 7 indicate the basic structure and the same functional parts.

The delivery device 10, as shown in FIG.
It moves forward toward the receiving member 26 as shown by arrow E, retreats from the receiving member 26 as shown by arrow F, and reverses by an angle of about 90° as shown by arrow G. The plate-shaped member 11 constituting the delivery device 10 is arranged on the forward direction side, and the plate-shaped member 12 is arranged on the backward direction side. A rotatable shaft is provided at the tip of the slide arm 19 that moves back and forth between the component receiving position X and the component fitting position Y relative to the receiving member 26 via a second shaft 25 attached to the member 12 Rearward movement is regulated by a fixed block 20 that is supported and fixed to the machine base.

Furthermore, stoppers 21 having a length that can protrude forward from the front end surface of the member 12 are attached to the upper part of the fixed block 20 so as to be located on both sides of the member 12. The upper part, that is, the end on the chute 22 side is pressed in the forward direction, and the upper part, that is, the end on the chute side of the member 11 and the member 12 is always kept slightly open against the elastic force of the spring 14. has been done.

Above the delivery device 10, the member 11
A chute 22 is disposed at a position corresponding to the axis of the hole 17 for receiving components formed by the holes 17 and 12. It is configured so that Further, in the forward and backward path of the slide arm 19 in front of the delivery device 10, the slide arm 1
A cam 23 is disposed to abut the lower part of the members 11 and 12, that is, the end on the side opposite to the chute 22 side, and rotate the members 11, 12 by approximately 90 degrees when the member 9 is advanced. In addition, cam 2
A receiving member 26 having a hole 24 into which the component M can be fitted is disposed in front of the receiving member 3 . When the receiving device 10 consisting of the hole 24 of the member 26 and the members 11 and 12 is rotated by 90 degrees, the receiving member 26 closes the hole 1 formed in the device 10.
It is arranged so as to correspond to the position of both axes.

To explain the operation of the parts delivery device having the above configuration, when the part M is delivered from the chute 22 to the delivery device 10, the members 11 and 12
is moved toward the fixed block 20 via the second shaft 25 by the backward movement of the slide arm 19. At this time, one member 11 comes into contact with the tip of the stopper 21 and cannot move further backward, and against the elastic force of the spring 14, the member 11 pivots on the first shaft 27 at the lower end. The upper part is slightly open. As a result, both members 11,
Hole 17 for receiving parts formed by 12
is in a wide open state, and the part M that is dropped when positioned directly below the chute 22 is easily fitted into the hole 17.

After that, the device 10 to which the part M has been delivered is moved forward by the slide arm 19.
When the other member 12 is moved to a position where it protrudes forward from the stopper 21, both members 11 and 12 are caused to close the hole 17 by the elastic force of the spring 14, and are thereby fitted into the hole 17. Component M is supported between members 11 and 12 under pressure. When the device 10 is further moved forward by the slide arm 19 in this state, its lower part comes into contact with the cam 23 disposed at the front, so that the members 11 and 12 move approximately forward in the forward direction about the second shaft 25. It can be flipped 90 degrees. At that time, hole 17
The axis corresponds to the axis of the hole 24 of the receiving member 26 disposed in front of the cam 23, and the part M clamped in the hole 17 by the forward movement of the device 10 is attached to the receiving member 26. It is press-fitted into the hole 24 of. At this time, the part M is supported by the hole 17 under pressure by the elastic force of the spring 14, so the relationship between the diameter of the part M and the diameter of the hole 17 is D-d≒0, which indicates the amount of protrusion. β becomes 0, and the component M is easily and reliably fitted into the hole 24 of the receiving member 26. When the part M is press-fitted into the hole 24, the device 10 holds the part M in the receiving member 2.
6 and then retreated again to the rear fixed block 20, and the plate-shaped members 11, 12 are returned to their initial upright state as shown in FIG. 5 by their own weight.

In the above action, the elastic force of the spring 14 is such that when the component M is press-fitted into the hole 24 of the receiving member 26 and the device 10 is retreated, the component M is
It is set so that it can be pulled out from the hole 17 of No. 2 and remain on the receiving member 26 side. The device 10 is also configured to be in its old upright position when returned to its initial position.

When the device 10 is returned to the position of the fixing block 20, the part M is again inserted into the holes 17 of the members 11 and 12, and the same operation as described above is repeated.

FIG. 8 shows the principle of the basic structure of the second embodiment of the delivery device, in which a large number of holes 17a are provided between members 11 and 12. When this device is used, a hole 24a corresponding to the hole 17a is also formed in the receiving member 26. By providing a large number of holes 17a and 24a in each of the device and the receiving member in this manner, it is possible to easily press-fit a connector pin, etc., all at once. Further, the hole 17a is formed by forming a groove only on the other member 12 side, and is formed by a combination of the groove and the flat part of the one member 11,
With this configuration, the device main body can be formed more easily.

The present invention has the above-described structure and function, and at the component receiving position, the holes of the two plate-like members forming the holes for supporting the component with pressure are resisted by the stopper against the elasticity of the spring. Since the hole is formed by a groove with a triangular cross section cut into at least one of the two plate-like members, the dimensional accuracy of the hole cannot be reduced that much. The effect is that the component can be easily received from the chute without having to raise the height, and when the component is moved forward by the slide arm and removed from the stopper, the component can be reliably pinched and supported by the elasticity of the spring, and the support is The action of the triangular grooves provides at least three-point support for reliable centering, which has the effect of realizing accurate delivery.

Furthermore, since the two plate-like members are held in elastic contact with each other by a spring, the component holding force can be adjusted to be strong or weak by selecting the elasticity of the spring.

Furthermore, since the component is moved to the component fitting position and fitted by the forward force of the slide arm, it has the effect of making it possible to press fit the component into the receiving member in combination with the above-mentioned component holding force. are doing.

Furthermore, the two plate-shaped members are rotated by a 90 degree angle by a cam during the forward movement process, which has the advantage of making the mechanism extremely simple.
