Abstract

PURPOSE:To enable a compression coil spring to be prevented from falling by providing a holder which houses a compression coil spring having a discharge portion one end side and having been elastically deformed into an approximate U shape, in such a manner that both its sides face toward the discharge portion side. CONSTITUTION:A compression coil spring 13 elastically deformed into an approximate U shape is housed inside a housing portion 2 in such a state that both ends face a discharge portion side 3. The compression coil spring 13 is held by a support 4 through having both right and left sides rebound-contact the support 4, and also both ends strike-contact the receiving surface 11a of a pair of support members 11. Hereupon, a holder 1 is carried to the upper portion of a recess 14 by means of a robot arm, and an air pressure cylinder 5 is driven and the support 4 is made to move downward. The support members 11, due to the downward movement of the support 4, moves downward along the inside surface of the housing portion 2, and a push-pressing member 6, too, moves downward. In that case, the compression coil spring 13 moves downward as it is being push-pressed by the push-pressing member 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a compression coil spring supply device that supplies a compression coil spring to a supplied portion in a linearly compressed state.

(Prior Art) In this type of conventional compression coil spring supply device, a compression coil spring is compressed in the axial direction and held between a pair of claw members, and after being conveyed in this state to a supplied part, the compression coil spring is There is one in which the spring is extruded from a pair of claw members and is supplied to the supplied portion.

(Problems to be Solved by the Invention) However, in the conventional compression coil spring supply device described above, when an attempt is made to compress the compression coil spring to a close contact state and hold it between the pair of claw members, the compression coil spring is seated. Since it bends and falls off the pair of claw members, it cannot be compressed very much, and therefore it is not suitable for cases where a strong spring force is required.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a compression coil spring supply device that can supply a compression coil spring in a highly compressed state to a supplied portion, and is free from the risk of the compression coil spring coming off and falling.

[Structure of the Invention] (Means for Solving the Problems) The compression coil spring supply device of the present invention has a compression coil spring elastically deformed into a substantially U-shape and has a discharge portion on one end side. A holder that is stored with the discharge section facing the side,
A pressing member is provided in the holder so as to be reciprocally movable, and has a pressing member that pushes out the compression coil spring from the holder by moving toward the discharge section side, and a receiving surface that receives both ends of the compression coil spring, and is reciprocally rotated to the holder. and a pair of supporting members that can be provided.

The pair of supporting members is configured so that as the pressing member moves in the extrusion direction, the receiving surfaces of both supporting members rotate from a state facing toward the back of the holder to a state facing each other, and the pressing member When the compression coil spring is moved in the extrusion direction, by pressing the compression coil spring with a pressing member while supporting both ends of the compression coil spring with a pair of support members, the compression coil spring is compressed into a linear shape between both support members. The device is characterized in that it is restored to its original state and then discharged from the holder.

(Function) 1-. According to the present invention as described above, the compression coil spring is approximately U
Since the compression coil spring is stored in the holder while being elastically deformed into a letter shape, there is no risk of the compression coil spring coming off and falling.

Moreover, when supplying the compression coil spring, both ends of the compression coil spring stored in the holder in a substantially U-shaped elastically deformed state are supported by a pair of support members, and the compression coil spring is pressed. , since the compression coil spring is restored to its compressed linear shape between both support members and discharged from the holder, the compression coil spring is greatly compressed 1
For example, it can be compressed into a dense layer and supplied to the supplied portion.

(Example) An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a holder attached to the arm of a robot (not shown), in which a storage section 2 is formed, and the lower end of this storage section 2 is connected to a discharge section 3.
It is said that Reference numeral 4 denotes a substantially inverted U-shaped support disposed within the storage portion 2 so as to be able to reciprocate downward, and a rod 5a of a pneumatic cylinder 5 attached to the upper part of the holder 1 is connected to this support. A pressing member 6 is disposed within the support 5 so as to be able to reciprocate in the vertical direction. Reference numeral 7 denotes a binion that is rotatably attached to the support 5 via a shaft 8, which includes racks 9 provided on both left and right inner surfaces of the storage section 2 and racks 10 provided on both left and right outer surfaces of the pressing member 6. It meshes with both.

Therefore, when the support 5 moves, the pressing member 6
It moves twice the distance at twice the speed.

Reference numeral 11 denotes a pair of support members in an abbreviated shape rotatably attached to both left and right sides of the lower end of the support 5 via a shaft 12, and the upper surface of the lower half of this support member receives both ends of the compression coil spring 13. The receiving surface 11a is used as a receiving surface 11a, and the outer surface of the other piece is used as a sliding surface 11b that slides into contact with the holder 1.

Next, the operation when the compression coil spring 13 is supplied into the recessed part 14, which is the part to be supplied, will be explained. A pin 15 equipped with a spring receiver 15a is provided in the recess 14 so as to be movable in the left-right direction, and the compression coil spring 13 is used to urge the pin 15 to the left in the drawing.

First, in FIG. 1, the support 4 is raised to the highest position by the pneumatic cylinder 5, and the support member 11
The sliding contact surface 11b is in sliding contact with the inner surface of the storage section 2, and the receiving surface 11a is located at the back of the storage section 2.

That is, it is in a state facing upward. A compression coil spring 13 elastically deformed into a substantially U-shape is housed in the housing section 2 with both ends facing toward the discharge section 3, that is, at the bottom. This compression coil spring 13 is housed in the housing part 2 by an insertion device (not shown), and is directly held by the support 4 with both left and right sides in elastic contact with the support 4.
Further, both ends are in contact with the receiving surfaces 11a of the pair of supporting members 11.

Now, in this state, the holder 1 is transported near the top of the four parts 14 by the arm of a robot (not shown), and is stopped there!
When hit, the pneumatic cylinder 5 is driven to move the support 4 downward. This downward movement of the support 4 causes the support member 11 to move downward along the inner surface of the storage section 2, and the pressing member 6 to move the pinion 7, rack 9, and
0, it moves downward in the extrusion direction at twice the speed and twice the length of the support member 11. Therefore, the substantially U-shaped compression coil spring 13 whose both ends are supported by the receiving surfaces 11a of the support member 11 moves downward while being pressed by the pressing member 6. Then, due to the movement of support 4, the third
As shown in the figure, when the support members 1 and 1 come to protrude downward from the discharge part 3, the compression coil spring 13
1 is rotationally biased in the direction of the arrow, this support member 11 moves the sliding surface 11b from the inner surface of the storage section 2 to the holder 1.
Rotate approximately 90 degrees in the direction of arrow A while sliding it on the lower end surface of the
As shown in FIG. 4, the receiving surfaces 11a of both supporting members 11 come to face each other. In the process in which the support member 11 rotates approximately 90 degrees in this manner, the pressing member 6, which moves at twice the speed and twice the length of the support member 11, presses the U-shaped deformed portion 13a of the compression coil spring 13. As a result, the compression coil spring 13 is gradually pushed between the pair of support members 11, and finally returns to a straight line between the support members 11. In this way, the compression coil spring 13 is approximately U
By restoring the compressed coil spring 13 into a straight line from the state where it was elastically deformed into a character shape, the compression coil spring 13 becomes in a state where it is compressed in a substantially intimate state between both support members 11, and in this state, the pressing member 6
presses down the compression coil spring 13, removes it from between the support members 11, and inserts it into the recess 14. Thereafter, the support 4 is pulled up by the pneumatic cylinder 5, so that the pressing member 6 and the support member 11 are moved upward, returning to the state shown in FIG.

According to the above configuration, the compression coil spring 13 is stored and held in the housing part 2 of the holder 1 in a state where it is elastically deformed into a substantially U-shape, so when the compression coil spring 13 is compressed into a tight state and held between the pair of claw members. In contrast, there is no risk that the compression coil spring 13 will buckle during transportation and fall off from the holder 1, and can be reliably transported to the recess 14.

Moreover, when the compression coil spring 13 is supplied to the recess 14, the compression coil spring 13 can be compressed linearly and supplied in a substantially close contact state. In this case, when the compression coil spring 13 returns to a straight line from the state of being elastically deformed into a substantially U-shape, the support member 11 that supports both ends of the compression coil spring 13 rotates as the compression coil spring 13 returns to its original state. Therefore, the compression coil spring 13 will not be excessively deformed, for example into a substantially Ω-shape, and there is no risk of plastic deformation.

Note that the present invention is not limited to the embodiments described above and shown in the drawings. For example, the support member is rotatably attached to a holder, and the support member and the pressing member are connected by a link mechanism or the like. Various modifications can be made without departing from the scope of the invention, such as a configuration in which the pressure member rotates as the pressing member moves.

[Effects of the Invention] As is clear from the above description, the present invention has a configuration in which a compression coil spring is elastically deformed into a substantially U-shape and stored in a holder. There is no risk of it falling.

Moreover, when supplying the compression coil spring, both ends of the compression coil spring are supported by a pair of supporting members that rotate as the pressing member moves in the extrusion direction, and the compression coil spring is pressed by the pressing member. Since the compressed linear shape is restored between the pair of support members, the compression coil spring can be compressed and supplied to a close contact state, and the compression coil spring will not be excessively deformed. , it is possible to obtain excellent effects such as being able to prevent plastic deformation.
