Abstract

PURPOSE:To enable coil springs to be fed in a state to be separated one by one, by a method wherein an air injection plate is situated to the bottom of the agitating chamber of a hopper, a guide part, formed in a V-shape in cross section, is located to a ceiling part,and a guide plate having an inclination guide part and a curved guide part is positioned to the outlet of a discharge chamber. CONSTITUTION:Air is injected through air injection holes 13, 13... into an agitating chamber 2, coil springs 4 are agitated in a floated state to disentangle entanglement of the coil springs with each other. An air flow is collided with guide parts 16 and 16 of a ceiling member 17 and is guided to outlets 5 and 5. Simultaneously, the coil springs 4 are carried to outlets 5 and 5 by means of an air flow and introduced to discharge ports 3 and 3. In this case, the opening size of the outlet 5 is set to a value lower than the length of the entangled closed type coil spring. Further, the shape of a curved guide part 23 is set so that the position of the center of gravity of the entangled open type coil spring is located in a position allowing it to float from a curved guide part 23 of a guide plate 21. This constitution enables the entangles coil springs to be reliably separated from each other to feed them one by one.

When only one coil spring 4 slides on the chute 6, the closing plate 26 does not open, so the coil spring 4 slides on the chute 6 until it comes into contact with the stopper 24. When the sensor 34 detects that the five coil springs 4 have passed through the notches 25 in this way, the supply of air from the air conduit 15 is stopped, and the discharge of the coil springs 4 is also temporarily stopped. . Therefore, during this time, the coil spring 4 on the chute 6 is recovered and the supply of air from the air conduit 15 is restarted, thereby restarting the supply of the next coil spring 4.

By the way, it is difficult to completely prevent the coil springs 4 from being drawn out into the discharge chamber 3 in a tangled state from the respective outlet ports 5, 5... It is also possible that it may fall from above. However, a notch 25 is provided in the middle of the chute 6, and the closing plate 25 that closes the notch 25 opens downward when two or more coil springs 4 are placed on it.
The coil springs 4 in which more than one coil spring is entangled fall onto the plate 33. Therefore, it becomes possible to reliably take out the coil spring 4 in a single state.

C1 Effects of the Invention As described above, according to the first device of the present invention, the bottom of the hopper is provided with a stirring chamber for floating and stirring a large number of coil springs and a discharge chamber outside both of the stirring chambers separated by a partition wall. An air blowing plate having air blowing holes is fixedly installed facing the stirring chamber, and an air conduit is connected to blow air from the air blowing holes into the hopper. A ceiling member is arranged opposite to the air jet plate to define the upper end of the stirring chamber, and is formed by interconnecting the lower ends of a pair of guide parts that are inclined in a direction that moves away from each other toward the discharge chamber and approaches the discharge chamber. A rectangular outlet with an opening dimension slightly larger than the outer dimensions of the coil spring is provided in the partition wall to connect the stirring chamber and the discharge chamber, and the outlet port is provided in the partition wall with a rectangular outlet opening that connects the stirring chamber and the discharge chamber. A guide plate consisting of an inclined guide part that is inclined to the side, and a curved guide part that is connected to the upper end of the inclined guide part, is smoothly curved, and is connected to the lower edge of the outlet port, and faces the stirring chamber and is connected to the partition wall. Since it is fixedly installed, it has a relatively simple configuration, and regardless of whether the coil springs are closed-end or open-end types, it is possible to separate coil springs that are entangled with each other and take them out one by one efficiently. becomes possible.

According to the second device of the present invention, in addition to the configuration of the first device, the bottom of the discharge chamber is formed by an inclined plate to allow the coil spring to slide down, and has a notch larger than the outer shape of the coil spring. A chute is connected to the hopper at the lower intermediate portion and is connected to the inclined plate, and has a closing plate at one end that can close the notch from below, and a rotary rond having a balance weight at the other end. The notch is rotatable between the position where the notch is closed by the closing plate and the position where the notch is opened, and is supported by the shade, and the weight of the balance weight is reduced when two or more coil springs are placed on the closing plate. Since the plate is set to rotate to the open position, in addition to the effect of the first device of the invention, it is possible to reliably eliminate coil springs that occasionally get tangled and slide down the chute. It is possible to further ensure that the springs are supplied one by one.
