The opening and closing mechanism comprises a convex disc 72 which is in rotating fit with the support 71, a ratchet ring 72a is arranged in the convex disc 72, a stop block 73 which is matched with the ratchet ring 72a is arranged at the end part of the rotating shaft 62, and abutting rods 74 which are matched with the connecting rod 65 are arranged on two sides of the convex disc 72.

A support rod 75 is fixed at the end of the rotating shaft 62, the stopper 73 is in rotating fit with the support rod 75, and a torsion element 76 is arranged between the stopper 73 and the support rod 75.

The inner sides of the contact rod 64 and the abutting rod 74 are both provided with rollers 8. The arrangement of the roller 8 can reduce the friction between the feeler lever 64 and the cam 63, and similarly, the roller 8 can reduce the friction between the catch lever 74 and the cam 72, and can reduce the wear between the parts.

When the switch plates 42 are closed, the butt joint of the switch plates 42 on the two sides is located at the lowest point. In this embodiment, the switch board 42 is in a V-shape structure after being closed.

The outer side of the material guiding plate 43 is provided with a hinge shaft 43a, the hinge shaft 43a is provided with a torsion spring 43b, and the hinge shaft 43a is connected with a driving member controlled by a controller.

The material guide plate 43 is provided with spacing bars 43c at intervals, which are matched with the spacing of the springs.

The driving member drives the hinge shaft 43a to rotate slowly, so that the spring on the material guiding plate 43 slides or rolls along the surface of the material guiding plate 43.

The upper end of the housing 41 is provided with a guide plate 41a having an upper portion inclined outward.

The conveying device 3 comprises a transmission belt 31 driven by a driving mechanism, and partition plates 32 are arranged on the transmission belt 31 at intervals.

The partition 32 is perpendicular to the surface of the belt 31.

The driving mechanism is a motor, the rotating device 61 is a motor, the return member 67 is a tension spring, and the partition plate 32 divides the transmission belt 31 into a plurality of transportation compartments.

The working principle is as follows:

after the spring is hot-rolled and formed on the spring machine 1, the spring machine 1 moves backwards integrally or the spring coiling rod 11 moves backwards, so that the spring falls into the material guiding mechanism 4, when the spring falls, the switch plate 42 is in a closed state under the action of the outer ejector rod 66, and a torsion spring is also arranged at the rotating shaft of the switch plate 42 and enables the switch plate 42 to tend to be opened.

The sensor 5 detects the position of the axis of the spring falling into the material guiding means 4 and the controller activates the vibrating means when the axis of the spring is not parallel to the line of closure of the shutter 42 (i.e. the axis of the spring is not parallel to the direction of the partition 32 on the conveyor 3). The sensor 5 may be a laser sensor, and the detection of the linearity of the workpiece by using laser is a prior art and will not be described herein. The rotating device 61 of the vibrating mechanism is started to drive the cam 63 on the rotating shaft 62 to rotate, when the narrow side of the cam 63 is in contact with the roller 8 on the contact rod 64, the ejector rod 66 connected with the connecting rod 65 is driven to move inwards under the action of the return piece 67, when the wide side of the cam 63 is in contact with the roller 8 on the contact rod 64, the force of the return piece 67 is overcome, the ejector rod 66 connected with the connecting rod 65 is driven to move outwards, and the ejector rod 66 reciprocates along with the rotation of the cam 63, so that a vibrating effect is generated, and the axis of the spring is parallel to the closing line of the switch plate 42. Since the switch plate 42 is in a V-shaped configuration when closed, the spring is located at the lower end of the switch plate 42.

When the vibration mechanism generates vibration, the rotating shaft 62 rotates counterclockwise, and the stop 73 mounted on the end of the rotating shaft 62 can move in the ratchet ring 72a without driving the cam 72 to rotate. After the position of the spring is adjusted, the controller sends out an instruction, the rotating device 61 rotates reversely, the rotating shaft 62 rotates clockwise, the stopper 73 acts on the concave teeth of the ratchet ring 72a to drive the convex disc 72 to rotate, the wide edge of the convex disc 72 abuts against the roller 8 on the abutting rod 74, so that the abutting rod 74 is pushed outwards, the abutting rod 74 drives the ejector rod 66 to move outwards through the connecting rod 65, the switch plate 42 loses the blocking of the ejector rod 66, the switch plate is opened under the action of gravity and torsion of the torsion spring, and the spring falls onto the material guide plate 43 below.

The material guide plates 43 on the two sides are arranged at intervals, so that the fall between the adjacent material guide plates 43 is reduced, and the collision damage when the spring falls is reduced. The articulated shaft 43a of the material guide plate 43 is connected with the driving piece, and the articulated shaft 43a is provided with a torsion spring 43b, so that the material guide plate 43 can rotate slowly, and further the occurrence of collision injury is prevented. The material guide plate 43 is provided with the spacing bars 43c, so that the spring can be prevented from deflecting on the material guide plate 43, and the axis of the spring is kept parallel to the partition plate 32 when the spring falls into the conveying device 3.

The spring falls along the guide plate 43, and because the axis of the spring is parallel to the partition plate 32, the spring can be ensured to accurately fall into the transportation grid of the transmission belt 31, thereby avoiding the influence on the stable operation of the transmission device 3 caused by the spring being blocked by the separation strip (partition plate 32) on the transmission belt 31, reducing the equipment failure and greatly improving the production efficiency.

While the preferred embodiments of the present invention have been illustrated, various changes and modifications may be made by one skilled in the art without departing from the scope of the present invention.
