Abstract

PURPOSE:To allow a clearance between parts at the next place as well as to make their takingout easy, by installing a bending member rotatably in position in close vicinity to a stopping part at the lower end of a tilted feeding device, while making up this bending member rotatably in an opposite direction to that of tilting by mans of an energizing device. CONSTITUTION:When an operator takes out a cylindrical part 2a, a bending member 3 pivotally attached to two side plates of a feed table 1 with a pin 4 rotates in an (a) direction by dint of resilience of a spring 5. Then, each of cylindrical parts 2b-2g gets rolling in a (b) direction with its dead load as their stoppage by release of a B end of the bending member 3. Then, the cylindrical part 2b hits the side of an A end of the bending member 3 and pushes the bending member 3 with its dead load so that it rotates in a (c) direction against the spring 5. Therefore, the cylindrical part 2b rolls as it is till it stops after hitting against a stopping part 6. On the other hand, the B end of the bending member 3 enters a clearance (d) between these cylindrical parts 2b and 2c and stops the parts beyond the cylindrical parts 2c.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a feeding device for parts having a cylindrical external shape.

Conventionally, in a device for supplying cylindrical parts, the supply path of the parts is inclined so that the parts automatically fall to a stopping point provided at a predetermined position.

That way, the part will always be in the stop, and if the stop is placed near the worker, the worker can take the part out without having to move.

However, in the conventional device, the parts were in contact with each other due to their own weight, so there was a drawback that it was difficult to remove the parts.

The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a component feeding device in which a gap is provided between the next component to be taken out and the next prepared component among the supplied components. With the goal.

The present invention will be explained below based on the drawings. 1st and 2nd
The figure is a side view of essential parts showing one embodiment of the feeding device of the present invention, and FIG. 3 is a front view of the same.

Reference numeral 1 denotes a supply table, and in this embodiment, two side plates are supported by one horizontal plate 8 as shown in FIG.

The interval between the two side rods is shorter than the length 4 of the cylindrical parts 2a to 2q. In addition, the supply table 1 has cylindrical parts 2a to 2q.
It is installed at an angle so that it rolls under its own weight. The cylindrical parts 28 to 2q are, for example, drums or shafts, and preferably have smooth surfaces. Reference numeral 3 denotes bending members, which are one of the features of the present invention, and are respectively attached to the side plates 2 & of the supply table 1 so as to be rotatable about a pin 4.

Note that) A' and B indicate both ends of this bent portion.

One end of the spring 5 is fixed near the end of the bending member 30B, and urges the bending member in the rotational direction indicated by the arrow (A).

This biasing force is extremely small. 7 is a pin that fixes the other end of the spring 6. Reference numeral 6 denotes a stop section provided at the front end of the supply table 1, and the cylindrical part 2a to be taken out next by the operator is regulated by this stop section 6 and stopped.

By the way, various shapes of the bent portion 3 can be considered. However, by attaching the bending member 3 far from the stop portion 6 and lengthening the A end, it is possible to increase the distance between the cylindrical parts 2a and 2b to be taken out next.

Next, the operation of the apparatus of this embodiment will be explained. The worker comes first
When the cylindrical part 2a is taken out from the state shown in the figure, the bending member 3 rotates in the direction of the arrow (A) due to the elastic force of the spring 6. As a result, it becomes as shown in Fig. 2. At this time, the cylindrical parts 2b~
2q, since the stop caused by the B end of the bending member 3 is released,
It begins to roll in the direction of the arrow (b) due to its own weight. Then, the cylindrical part 2b hits the A end side of the bending member 3 and pushes the bending member 3 with its own weight. Since the biasing force of the spring 5 is set to be very small, the moment due to the pushing force of the cylindrical member is larger than the moment due to the biasing force of the spring 6 against the bending member 3, and the bending member 3 is Rotate in the direction of line (c). At this time, the bending member 30B end is configured to enter into the gap between the cylindrical parts 2b and 20, and the cylindrical parts 2C and subsequent parts are locked by the B end. On the other hand, the cylindrical part 2b continues to roll until it hits the stop 6 and stops.

As a result of the above, the state returns to the state shown in FIG. In this way, the cylindrical parts are fed one after another, and a gap is provided between the next part to be taken out and the next part.

Next, other embodiments of the present invention will be described. FIGS. 4 and 5 are side views of main parts of other embodiments of the present invention. In this embodiment, instead of a cylindrical part, a part having a rotatable shaft protruding from the center of a cylindrical member will be used as the supplied part. In FIG. 4, reference numerals 88 to 8c are supply parts having a rotatable shaft portion at the center of a cylindrical member, 9 is a side plate of the supply table, 10 is a bending member, and 11 is a spring. In the supply parts 8a to 8c, only the protruding shaft portion is attached to the side plate 9 of the supply stand.
is in contact with the top surface of the In this embodiment as well, when the supplied part 8a is taken out, the bent portion 1o rotates about the bottle 12 in the direction of arrow a (e) in FIG. 5 due to the attractive force of the spring 11.

At the same time, the supplied parts sb and 8c roll along the side plate 9 in the direction of the arrow in FIG. This is because the shaft is rotatable relative to the cylindrical member. When the shaft of the component 8b comes into contact with the bending member 1o, the bending member 10 moves along the arrow line (E).
and rotate in the opposite direction. In this case, the end of the bending member 1o on the side where the spring 11 is attached is connected to the shaft of the component 8b and the component 8.
The part 8c protrudes between the part 8c and the axis of the part 8c, and stops the rolling motion of the part 8c. On the other hand, the part 8b continues to roll and the shaft is at the stop 1.
It stops when it hits 3, and it becomes as shown in Figure 4. Thereafter, parts having a rotatable shaft portion at the center of the cylindrical member are sequentially supplied in the same manner, and a gap can be provided between the part 2 to be taken out next and the next part.

Note that the shape of this component is not limited to a cylindrical shape.
- As described above, according to the present invention, the supply means is provided with an inclination, the stop portion provided at the lower end of the supply means, and the supply means near the stop portion is rotatable about the bent portion. niV
Since it is equipped with a bending member attached in a shape and a biasing means for rotating the bending member in a direction opposite to the direction of inclination, the operator can easily move the bending member between the parts list to be taken out and the next part. A gap can be provided, making it extremely easy for the operator to take out parts.
