Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a device for arranging so-called coil springs made of wire wound into a coil shape in a line while untangling them.

Conventional technology Coil springs are easy to get entangled with each other, and once they are entangled, they are easy to unravel. Therefore, when aligning coil springs in a line using a conventional well-known vibrating parts feeder, the entangled springs had to be manually unraveled, which was a hassle. .

Therefore, in order to omit the above-mentioned trouble, we decided to
A device as described in Japanese Patent No. 23774 has been proposed. This involves installing a bottomed entangled spring separation container with an open top and a rotating disk with blades on the top surface on the parts feeder main body. A large-diameter bowl with a spiral alignment path having a starting end on the bottom is provided, and in the middle of a carry-out passage connected to the end of the alignment passage of this bowl, two or more tangled springs are removed from the carry-out passage. A device comprising a sorting mechanism and a coiled spring collection passage configured to guide the coiled springs removed from the carry-out passage by the sorting mechanism into the coiled spring separation container, the device comprising a spiral alignment passage provided in the bowl. While the coil springs are sequentially aligned and sent along the carry-out passage, the coil springs that are entangled are removed at the sorting mechanism location, and only the springs that are not entangled are sent out along the carry-out passage in an aligned state. The entangled springs excluded by the sorting mechanism are introduced into an entangled spring separation container having a rotating disk, and while they are temporarily stored in the entangled spring separation container, a strong unraveling action is applied to them by the blades of the rotating disk, By returning the untangled springs to the bowl again by taking advantage of the fact that the untangled springs jump up higher than when they were entangled, the coil springs are untangled and aligned.

According to this device, when aligning the coil springs, the work of manually untying the entangled springs can be omitted, and the alignment work can be automatically and efficiently performed while untying the entangled springs.

Problems to be Solved by the Invention Incidentally, in the above-mentioned coil spring alignment device, since the entangled spring separation container and the bowl are placed on the parts feeder main body, the height of the entire device becomes undesirable. That is, when the height of the entire device increases, not only does the device become unstable, but it also looks unsightly. Further, since the entangled spring separation container, bowl, carry-out passage, and entangled spring collection passage are all vibrated by the parts feeder main body, a large amount of noise is generated and a large amount of power is required for the parts feeder main body.

Means for Solving the Problems In view of the above-mentioned problems, this invention aims to improve and eliminate the problems by supporting the lower mass vibrating body with the lower mass through support plate springs, and supporting these lower mass vibrating bodies through support plate springs. and a parts feeder main body, which has an electromagnetic core on one side of the upper vibrating body, and a movable core that corresponds to the electromagnetic core through a gap and is attracted to the electromagnetic core on the other side, and a rotating disk having blades on its upper surface at the bottom. A cylindrical entangled spring separation container with an open top surface, a large-diameter bowl equipped with a spiral alignment passage having a starting end at the bottom surface on the inner periphery of the cylindrical part, and a conveyance passage connected to the terminal end of the spiral alignment passage of the bowl. and a coil spring array comprising a sorting mechanism for removing two or more entangled entangled springs from the carrying out passage, and an entangled spring collection passage for introducing the entangled springs removed from the carrying out passage by the sorting mechanism into the entangled spring separation container. In the apparatus, the entangled spring separation container is attached to the lower vibrating body of the parts feeder main body, and the bowl is arranged on the outer periphery of the upper end of the entangled spring separation container concentrically with the entangled spring separation container. It is attached to the upper vibrating body of the main body.

Function When the parts feeder body is operated, the lower vibrating body, which has a large mass, vibrates slightly, and the upper vibrating body, which has a small mass, vibrates greatly. The entangled spring separation container hardly vibrates, and only the bowl attached to the upper vibrating body vibrates greatly.

Embodiment FIGS. 1 and 2 are a front vertical sectional view and a partially cutaway plan view showing an embodiment of the coil spring aligning device according to the invention. In the same figure, 1 is the installation stand 2
In the parts feeder body placed above, a lower vibrating body 4 with a large mass is fixed on the installation base 2 via a vibration isolating rubber 3, and the lower vibrating body 4 is tilted at a predetermined angle at an appropriate number of points in the circumferential direction. An upper vibrating body 5 with a small mass is supported via a plurality of support leaf springs (not shown) arranged in the same direction, an electromagnetic core is provided in one of the lower vibrating body 4 and the upper vibrating body 5, and the electromagnetic core is provided in the other. and a vibrator (not shown) in which a corresponding movable core is provided with a predetermined gap between them, and an intermittent attractive force is applied to the movable core by intermittently exciting the electromagnetic core of the vibrator. This suction force is used to generate vibrations in opposite phases between the lower vibrating body 4 and the upper vibrating body 5 by the repulsive elasticity of the support plate spring. Note that the magnitude of vibration of the lower vibrating body 4 and the upper vibrating body 5 is inversely proportional to the magnitude of their respective masses. Therefore, the lower vibrating body 4 having a large mass vibrates small,
Further, the upper vibrating body 5 having a small mass vibrates greatly. Reference numeral 6 denotes an entangled spring separator built into the parts feeder body 1. A cylindrical container body 7 is vertically fixed to the lower vibrating body 4 of the parts feeder body 1, and a drive motor is installed at the bottom of the container body 7. A rotary disk 9 is provided which is rotationally driven by a rotating disk 9, and a blade 10 is provided on the upper surface of the rotating disk 9, and a spacer 12 is provided which has a plurality of spring pop-out windows 11 at an appropriate number of locations in the circumferential direction at the upper open end of the container body 7. Ceiling board 13 is being installed. Reference numeral 14 denotes a large-diameter bowl arranged concentrically with the entangled spring separation container 6 on the upper outer periphery of the entangled spring separation container 6 and attached to the upper vibrating body 5 of the parts feeder main body 1. A spiral alignment passage 17 having a starting end on the bottom plate 15 is provided on the inner circumferential surface of the cylinder 16. Reference numeral 18 indicates that the cylindrical body 16 is attached to the outer circumferential portion of the cylindrical body 16 of the bowl 14.
This is an unloading passageway that surrounds approximately one-fourth of a circle.
The starting end is connected to the terminal end of the spiral alignment path 17, and the other end is extended in the tangential direction to the cylindrical body 16 and connected to the next process, and two or more entangled springs are excluded in the middle. A sorting mechanism (not shown) and a coiled spring collection passage 19 are provided for guiding the coiled springs removed by the sorting mechanism into the coiled spring separation container 6.

In the above configuration, the coil spring contained in the bowl 14 is attached to the bowl 1 by the parts feeder main body 1.
The spiral alignment path 1 is formed by the reciprocating rotational vibration of 4.
7, they are sent upwards while being arranged in a line from the starting end, and at the end of the alignment path 17, they move onto the carry-out path 18, and thereafter are sent along this.

Some of the coil springs sent along the carry-out passage 18 are entangled with each other, but when these coil springs reach the sorting mechanism, they are removed from the carry-out passage 18 to the entangled spring collection passage 19 at the sorting mechanism. Only the untangled coil springs pass through the sorting mechanism, are arranged in a line, and sent to the next process.

On the other hand, at the sorting mechanism location, the carry-out passage 18
The entangled springs removed from the entangled spring recovery passage 19 are sequentially sent from the entangled spring recovery passage 19 into the entangled spring separation container 6. The entangled spring that has entered the entangled spring separation container 6 moves violently due to the rotation of the rotating disk 9 provided at the bottom of the entangled spring separation container 6, and collides with the rotating disk 9 and the blades 10 during the movement. As it expands, contracts, and bends, it is at this time that the tangles come loose. The untangled coil spring becomes lighter and has greater spring elasticity than when it is entangled, so the coil spring jumps a lot the moment it is untangled, and the spacer 12 is inserted into the upper opening end of the container body 7 of the entangled spring separation container 6. The spacer 12 collided with the ceiling plate 13 installed
are automatically sent out one after another from the spring pop-out window 11 to the bowl 14, and subjected to the alignment operation again.

By the way, according to the above-described coil spring alignment device, the entangled spring separation container 6 is built into the center of the parts feeder body 1 except for the upper end portion thereof, so that the height of the entire device can be kept low.

In addition, in this coil spring alignment device, the entangled spring separation container 6 is attached to the lower vibrating body 4 of the parts feeder main body 1, and the bowl 14 is attached to the upper vibrating body 5 of the parts feeder main body 1. Only the bowl 14 can be vibrated with almost no vibration.

Effects of the invention According to this invention, since the height of the entire device can be kept low, the entire device can be downsized, the stability of the device is improved, and the appearance is good. In addition, since it is possible to vibrate only the bowl without vibrating the entangled spring separation container,
Noise can be kept low, and the power of the parts feeder itself is small.
