The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the present invention is illustrated further.

As Fig. 1, shown in 2, of the present invention minute spring feed mechanism comprises conduit 1, lead spring joint 2, photoelectric sensor 3, minute spring support 4, bottom guide 5, upper guide plate 6, minute spring plank 7, snap rivet 8, Compress Spring 9, impeller-hub 10, contiguous block 11, hex nut 12, nut 13, stage clip cylinder 14, the push-in nipple 15 of L-type, choke valve 16, straight pin 17, hexagon socket cap head screw 18, resistance spring piece 19, Y type Compress Spring 20, prevention cover 21.

on minute spring support 4 fronts, be equipped with respectively the lower end, bottom guide 6, 5, spring joint 2 is housed below bottom guide 5, the interior conduit 1 that is equipped with respectively of upper guide plate 6 and spring joint 2, on, bottom guide 6, 5, in be provided with the spring passage, the spring passage that is positioned at upper guide plate 6 lower ends is provided with resistance spring piece 19, on, bottom guide 6, minute spring plank 7 is housed between 5, divide spring plank 7 to be provided with through hole, minute spring plank 7 rear ends are fixedly connected with stage clip cylinder (14) on being fixed on minute spring support 4 rear end faces by contiguous block 11, divide to be provided with in spring support 4 and blow the spring passage, blow the spring passage and blow the spring cylinder and be connected, impeller-hub 10 and Compress Spring 9 are housed above contiguous block 11, after moving to left, impeller-hub 10 pushes down resistance spring piece 19.Be provided with the prevention cover 21 for observation and regular maintenance in upper guide plate 6.Bottom guide 5 lower end side are equipped with photoelectric sensor (3).Blow the spring cylinder air inlet and connect choke valve 16.Divide the movement of spring support 4 by machinery or automation equipment drivings such as cylinder, cam mechanisms.

As shown in Figure 3, according to the design sequence requirement, receive blow the spring instruction after, at first stage clip cylinder 14 moves, and then waits for the spring detection signal that puts in place, if there is no signal, illustrating that spring does not enter smoothly blows the spring passage, and this moment, the operator can manually add the spring operation.If the spring signal detected, stage clip cylinder 14 resets, and blows the action of spring cylinder, blows, and time-delay 0.5s after-blow spring cylinder stops blowing (stopping blowing according to the signal input condition during debugging mode), and flow process finishes.
