Description

[Detailed Description of the Invention] The present invention relates to a component supply device that supplies cylindrical, spherical, etc. components.

As a parts feeding device for cylindrical or spherical parts 1 as shown in FIG. There is a system in which the parts 1 are lifted up and transferred to an inclined chute in a line for supply.

However, in the conventional device of this kind, the upper surface of the inclined chute 2 is adjusted to the shape of the part, as shown in FIG. 2A or B.
Since it is formed in the groove 3 or U groove 4, the parts 1 may get caught near the exit of the inclined chute 2, or the parts 1 may become full on the parts storage side and piled up on the inclined chute 2. The outlet of the inclined chute 2 may become clogged due to the weight of the component 1.

Therefore, it is necessary to install a parts removal device near the exit of the inclined chute 2 to drop the parts 1 on the inclined chute 2 when the part 1 becomes clogged, and also to detect the full state as a countermeasure against fullness. When the component 1 becomes full, it is necessary to detect this and stop the vertical movement of the blade.

In view of the above-mentioned conventional problems, the present invention is capable of self-correcting parts caught on the inclined chute without using any special additional equipment, and also prevents parts from getting caught on the inclined chute even when the parts are full. To provide an inexpensive and compact parts supply device in which parts are returned to a parts storage part by natural fall.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment.
In the figures, 5 is a base plate, 6 is an outer frame attached to the base plate 5, and the inside of the outer frame 6 is used as a parts storage section 7 in which parts 1 are stored.

Reference numeral 8 denotes an inclined chute, which is attached to the base plate 5 at an inclination angle such that the component 1 is dropped downward by natural fall, and a cylindrical external chute 9 is connected to its tip.

A blade 10 transfers and supplies the parts 1 from the parts storage section 7 onto the inclined chute 8, and is vertically slidable along the inclined chute 8 by a drive device (not shown).

As shown in FIG. 6, the inclined chute 8 has an inclined surface 8a such that the end on the side of the blade 10 in the transverse direction is lowered, and the upper end surface of the blade 10 has a lower end on the side of the inclined chute 8 in the transverse direction. It has an inclined surface 10a as shown in FIG. 1, and has horizontal ridges in the longitudinal direction.

Next, the action will be explained.

When the blade 10 is raised from the lowest position of the parts storage section 7, the upper end surface of the blade 10 is an inclined surface 10a, so that the parts 1 in the parts storage section 7 are moved upward from the blade 10 as shown in FIG. 7A. They are lifted up while being placed in a line on the inclined surface 10a.

When the upper end of the blade 10 intersects the inclined chute 8, the parts 1 on the blade 10 sequentially fall onto the inclined chute 8 from the intersection side as shown in FIG. It is dropped from.

Due to some reason, the inclined chute 8 as shown in Figure 7C
If the part 1 is jammed at the outlet of the blade 10, as the blade 10 descends downward as shown in the figure, the part 1 on the inclined chute 8 will naturally fall into the parts storage part 7, and as a result, Self-correcting.

This is the same when the part 1 is full, so even when the part 1 is in the external chute 9, there is no need to stop the blade 10, and there is no need for a detector to detect that the part 1 is full. Therefore, when a large number of parts 1 of various types are supplied in many directions, this becomes a major factor in reducing the cost of the apparatus.

Incidentally, Fig. 8 A, B,
Measurements were made in the manner shown in C and D, and the results were as follows.

A is a conventional device in which the inclined chute 2 is made into a groove 3, B-D is the device of the present invention, B is a device with an inclined surface 8a of 10 degrees, and C is a device with a groove of 1.
There is also a note that it is 5° and D is 20°.

When the average supply amount per minute is measured for each under the same conditions, in A, once a component is caught, subsequent supply is impossible, and a component removal device is required.

110-126 pieces/min on the 10' slope of B, 1 of C
On an inclined surface of 5 degrees, it is 125 to 137 pieces/min, and on an inclined surface of 20 degrees D, it is 140 to 146 pieces/min.If the angle of the inclined plane is increased, the part 1 will be caught at the outlet of the inclined chute Even in this case, the possibility of the blade 10 falling naturally increases each time it descends, resulting in an increase in the amount of supply per minute.

In this case, the component 1 has a cylindrical shape with a diameter of 2 mm and a length of 6 mm, and the blade 10 has a width of 2 mm and a length in the longitudinal direction of 120 mm.

The cycle time of the blade 10 is 4.8 seconds each time.

As described in detail in the embodiments above, in the present invention, both the inclined chute and the blade are formed into an inclined surface so that the corresponding side is lower. There is no need for a full parts removal device, and even when the parts are full, the parts accumulated on the inclined chute will naturally fall to the parts storage section, so there is no need for a fullness detector, and the blade movement can be controlled. Electrical wiring and the like for stopping the system are not unnecessary.

Therefore, since it is structurally very simple, it is possible to reduce the cost and make the whole device significantly more compact, especially in devices that supply a large number of types of parts.
