The pushing and rotating mechanism comprises two swinging plates 102 which are parallel to each other, the two swinging plates 102 are spaced from each other, the swinging plates 102 are triangular plates, and a lightening hole is formed in the middle of the swinging plates 102. For convenience of description, the spacing direction of the two swing plates 102 is defined as the left-right direction, the rolling direction of the spool 400 is defined as the front-back direction, and the spool 400 is defined as the spool rolling from the back to the front. The front end of the swing plate 102 is hinged to the first base 101 around an axis extending from left to right, specifically, a bearing seat 103 is installed on the first base 101, and the swing plate 102 is hinged to the bearing seat 103 through a first rotating shaft 104.

A push rod 105 is connected between the rear ends of the two swing plates 102, and the two swing plates 102 can drive the push rod 105 to swing back and forth. When the spool 400 is not supported on the first base 101, the swing plate 102 drives the push rod 105 to swing backwards to avoid the spool 400, at this time, the upstream spool 400 can roll between the two swing plates 102, and then the swing plate 102 drives the push rod 105 to swing forwards and pushes the spool 400 forwards, so that the spool 400 rolls forwards.

In order to drive the swing plates 102 to swing back and forth, as shown in fig. 2, power cylinders 106, which may be air cylinders or oil cylinders, are respectively installed between the two swing plates 102 and the first base 101. The rear end of the power cylinder 106 is hinged on the first base 101, specifically, a support 107 is fixedly mounted on the first base 101, and the rear end of the power cylinder 106 is hinged on the support 107. The front end of the power cylinder 106 is hinged on the swing plate 102, specifically, the swing plate 102 is rotatably provided with a second rotating shaft 108, the front end of the power cylinder 106 is provided with a top rod 109, and the top rod 109 is connected with the second rotating shaft 108. As shown in fig. 2, three apexes of the swing plate 102 correspond to the front end of the power cylinder 106, the first rotation shaft 104, and the support 107, respectively. The swing plate 102 can be driven to swing back and forth by the extension and contraction of the power cylinder 106.

Two limiting grooves 111 are formed in the middle of the first base 101, the two limiting grooves 111 extend forwards and backwards and are arranged at left and right intervals, the limiting grooves 111 limit the spool 400, and the spool 400 cannot roll when waiting to be pushed.

An avoiding groove 114 is formed in the rear end of the first base 101, the avoiding groove 114 is used for avoiding the push rod 105, so that the push rod 105 can sink into the avoiding groove 114 and be lower than the plate surface of the first base 101, and therefore, when the spool 400 enters the station from the previous station, no object protrudes upwards out of the first base 101, and the spool 400 can smoothly enter between the two guide plates 110. A communication groove 113 is formed in the front end plate surface of the first base 101, and the purpose of the communication groove 113 is to allow a power line and a fluid pipeline (such as an air pipe or a hydraulic oil pipe) required for connecting the two power cylinders 106 to pass through without affecting the rolling of the spool 400.

The first detecting structure 112 is further installed on the first base 101, the first detecting structure 112 is used for detecting whether the spool 400 is on the first base 101, the first detecting structure 112 is connected to the power cylinder 106, and when the first detecting structure 112 detects that the spool 400 is on the first base 101, the power cylinder 106 extends out. The first detection structure 112 may be a proximity switch or a travel switch.

The use process of the push-turn mechanism is as follows: as shown in fig. 4, the power cylinder 106 is in a retracted state, and the spool 400 can enter the current station from the previous station; as shown in fig. 5, after the spool 400 enters the present station, the power cylinder 106 extends out and drives the push rod to push the spool forward; as shown in fig. 6, the cylinder 106 is extended to the extreme position pushing the spool 400 away from the home position, after which the cylinder 106 is retracted to the position shown in fig. 4, and a cycle is complete.

The structure of the second pushing unit 200 is similar to that of the first pushing unit 100, and is not described herein again.

As shown in fig. 7 to 11, the third pushing unit 300 is a reversing unit, the base of the third pushing unit 300 is a disc 302, and the disc 302 can rotate around its own axis, and like the pushing and reversing mechanism, the avoiding groove, the guide plate, the limiting groove, the communicating groove and the like in the first pushing unit 100 are all arranged on the disc 302.

In order to drive the disc 302 to rotate in place, as shown in fig. 7, 8 and 9, a rotation driving mechanism is mounted on the disc 302, wherein the rotation driving mechanism comprises two sets of driving wheel assemblies 303 and two sets of driven wheel assemblies 304, and the driving wheel assemblies 303 and the driven wheel assemblies 304 are eccentrically arranged. The driving wheel assembly 303 is configured as shown in fig. 8, the driving wheel assembly 303 includes a motor 309, a speed reducer 310, a driving roller mounting seat 307, a driving roller 308, and two chain wheels 311, a bottom of the driving roller mounting seat 307 is fixedly mounted on the disk 302, the driving roller 308 is rotatably mounted on the driving roller mounting seat 307, a bottom of the driving roller 308 protrudes downward from the disk 302 by a certain height and is supported on the ground, and the driving roller 308 supports the disk 302. The motor 309 and the speed reducer 310 are mounted on the driving roller mounting seat 307, the two chain wheels 311 are respectively mounted on an output shaft of the speed reducer 310 and a shaft where the driving roller 308 is located, and the two chain wheels 311 are connected through a chain 312 to realize power transmission. The motor 309 increases torque through the speed reducer 310 and then drives the driving roller 308 to rotate through the two chain wheels 311.

The driven wheel assembly 304 comprises a driven wheel mounting seat 313 and a driven wheel 314, wherein the driven wheel 314 is rotatably mounted on the driven wheel mounting seat 313, the bottom of the driven wheel mounting seat 313 is fixedly mounted on the disc 302, the bottom of the driven wheel 314 protrudes downwards from the disc 302 for a certain height, and the disc 302 is supported by the driven wheel 314 to be away from the ground. When the arrangement is performed, the driving pulley assembly 303 and the driven pulley assembly 304 are arranged separately in the circumferential direction, and the disc 302 can be supported smoothly.

In order to limit the rotation of the disc 302, so as to ensure that the disc 302 rotates around its own axis in situ, the third pushing unit 300 further includes a limiting structure, specifically, the limiting structure includes a fixing plate 301, an arc groove is formed on the fixing plate 301, and an arc groove is also formed on the base of the second pushing unit 200. The limiting structure further comprises four limiting assemblies 305, and the four limiting assemblies 305 are respectively arranged on the fixing plate 301 and the base of the second pushing unit 200.
