The carrier driving device comprises a driving chain 1, a pushing component 3 arranged on the driving chain 1 and a limiting component 2 arranged on the driving chain 1 opposite to the pushing component 3; the carrier 5 is accommodated in the accommodating area 6 between the pushing component 3 and the limiting component 2, a carrying channel 7 for the carrier 5 to enter the accommodating area 6 is arranged below the limiting component 2, the carrying channel 7 can be opened or closed by the limiting component 2, and the pushing component 3 pushes the carrier 5 positioned in the accommodating area 6 to move on the side hanging rail 4 under the driving of the driving chain 1, so that the specific effect is shown in fig. 1.

In the utility model, a pushing component 3 and a limiting component 2 are arranged on a driving chain 1, the pushing component 3 and the limiting component 2 are oppositely arranged on the driving chain 1 and are separated by a certain distance, and a containing area 6 for containing a carrier 5 is formed between the pushing component 3 and the limiting component 2. A carrying channel 7 is arranged below the limiting assembly 2, and the limiting assembly 2 can open or close the carrying channel 7. When the limit component 2 opens the carrying channel 7, the carrier 5 passes through the carrying channel 7 and enters the accommodating area 6; after the carrier 5 enters the accommodating area 6, the limiting component 2 closes the carrying channel 7, and at the moment, the driving chain 1 is started, so that the pushing component 3 and the limiting component 2 on the driving chain 1 synchronously move along with the driving chain 1, and the pushing component 3 pushes the carrier 5 in the accommodating area 6 to move on the side hanging rail 4, so that the carrier 5 can run on the side hanging rail 4.

Because the pushing component 3 pushes the carrier 5 to move on one side of the carrier 5, and the limiting component 2 pushes the carrier 5 to limit on the other side of the carrier 5, when the driving chain 1 drives the pushing component 3 to push the carrier 5 to move on the side-hanging track 4, the limiting component 2 limits the carrier 5 in the accommodating area 6, when the driving chain 1 is started, the carrier 5 moves synchronously along with the driving chain 1, and when the driving chain 1 stops moving, the carrier 5 stops moving synchronously, so that the carrier 5 is transported, the carrier 5 is limited to move on the side-hanging track 4, and the hanging density and the running position of the carrier 5 are controlled conveniently, thereby meeting the requirements of different procedures.

In this embodiment, a transport platform 41 for hanging a carrier 5 is arranged at the bottom of the side hanging rail 4, the driving chain 1 is hung at the top of the side hanging rail 4 and is slidably connected with the side hanging rail 4, and a sliding rib 42 for limiting the roller 51 is axially arranged in the middle of the transport platform 41, so that the specific effects are shown in fig. 1 and 2. The bottom of the side hanging rail 4 is provided with a transportation platform 41, the carrier 5 is hung on the transportation platform 41, and the driving chain 1 is hung on the top of the side hanging rail 4 and is in sliding connection with the side hanging rail 4. It is envisioned that: the top of the side hanging rail 4 is provided with a chute, the upper end of the driving chain 1 is in sliding fit with the chute, and the driving chain 1 moves in the chute under the driving of the power mechanism, so that the pushing component 3 and the limiting component 2 on the driving chain 1 are driven to synchronously move.

The pushing component 3 and the limiting component 2 are fixed at the lower end of the driving chain 1, and extend downwards at the lower end of the driving chain 1, so that when the pushing component 3 and the limiting component 2 move synchronously along with the driving chain 1, the pushing component 3 applies acting force to the carrier 5 positioned on the transport platform 41 below, the carrier 5 is pushed to run on the transport platform 41, and the limiting component 2 limits the carrier 5 positioned on the transport platform 41 below and limits the carrier 5 in the accommodating area 6, so that the carrier 5 and the driving chain 1 move synchronously or stop. The middle part axial at transport platform 41 is equipped with sliding rib 42, and when carrier 5 axially moved on transport platform 41, sliding rib 42 carries out spacingly to carrier 5, prevents that it from breaking away from transport platform 41 in the operation in-process, leads to the transportation of carrier 5 to be unable to accomplish.

In this embodiment, the carrier 5 includes a roller 51 cooperating with the transport platform 41, a hanger 52 for mounting the clothing, and a link 53 for connecting the roller 51 and the hanger 52, and when the limiting assembly 2 opens the carrying channel 7, the roller 51 enters the accommodating area 6 from the carrying channel 7, and the pushing assembly 3 pushes the roller 51 to move on the transport platform 41, as shown in fig. 1 and 3. The carrier 5 includes a hanger 52, a roller 51, and a link 53, the hanger 52 is mounted with the cloth, the roller 51 is engaged with the transport platform 41, and the link 53 connects the hanger 52 with the roller 51. When the limit assembly 2 opens the carrying channel 7, the rollers 51 on the carrying platform 41 enter the accommodating area 6 from the carrying channel 7; after the roller 51 enters the accommodating area 6, the limiting assembly 2 closes the carrying channel 7, and when the pushing assembly 3 pushes the roller 51 to roll along the conveying platform 41, the limiting assembly 2 limits the roller 51 in the accommodating area 6, so that the carrier 5 can be driven to run on a conveying track, the conveying of cloth is realized, and the running of the carrier 5 on the side hanging track 4 can be limited.

Since in the present utility model, the carrier 5 rolls on the transport platform 41 through the rollers 51, so as to realize the transport of the carrier 5 on the transport platform 41, and when the pushing component 3 pushes the rollers 51 to roll on the transport platform 41, the limiting component 2 limits the rollers 51 in the accommodating area 6, so that the diameter of the accommodating area 6 is larger than that of the rollers 51 in order to prevent the accommodating area 6 enclosed by the pushing component 3 and the limiting component 2 from obstructing the rolling of the rollers 51. If the diameter of the accommodating area 6 is far greater than that of the roller 51, the limiting effect of the limiting assembly 2 on the carrier 5 is affected, so that in the utility model, the diameter of the accommodating area 6 is preferably greater than that of the roller 51 and less than twice that of the roller 51.

In this embodiment, the limiting assembly 2 includes a switch base 21 fixed on the driving chain 1, and a switch plate 22 rotatably connected to the switch base 21, where the carrying channel 7 is located below the switch base 21, and the switch plate 22 can rotate upward or downward on the switch base 21 by a certain angle to open or close the carrying channel 7, as shown in fig. 1 and 4. The pushing assembly 3 comprises a switch base 21 and a switch plate 22, wherein the switch base 21 is fixed at the lower end of the driving chain 1, and the top of the switch plate 22 is rotatably connected with the switch base 21.

When the roller 51 enters the accommodating area 6, it is no longer abutted against the switch plate 22, and the switch plate 22 rotates downward by a certain angle with the rotation connection point of the switch base 21 as the center of circle under the action of gravity, so as to restore the state of extending vertically downward on the switch base 21, and close the carrying channel 7. Since the switch plate 22 is limited in downward rotation when extending vertically downward on the switch base 21, the roller 51 located in the accommodating area 6 abuts against the switch plate 22 at this time, and the switch plate 22 cannot be rotated, so when the pushing assembly 3 pushes the roller 51 to roll on the transport platform 41 at one end of the roller 51, the switch plate 22 limits the roller 51 at the other end of the roller 51, so that the roller 51 cannot move out of the accommodating area 6 through the carrying channel 7, and the roller 51 is limited in the accommodating area 6.

It is envisioned that: to realize the driving of the carrier 5 of the transport platform 41 by the driving device, the driving chain 1 stops running initially, the roller 51 of the carrier 5 is mounted on the transport platform 41, and the roller 51 is positioned in front of the pushing component 3 and the limiting component 2 on the driving chain 1. The drive chain 1 is then activated, so that the pushing assembly 3 and the limiting assembly 2 are moved in the direction of the roller 51 under the drive of the drive chain 1. Because the spacing component 2 is located on one side of the driving chain 1, which is close to the roller 51, when the spacing component 2 and the pushing component 3 reach the position of the roller 51, the switch plate 22 of the spacing component 2 is abutted with the roller 51 stopped on the transportation platform 41 under the driving of the driving chain 1, so that the roller 51 pushes the switch plate 22 to rotate upwards towards the direction of the pushing component 3, the carrying channel 7 below the switch base 21 is opened, the roller 51 can enter the accommodating area 6 through the carrying channel 7, the pushing component 3 can push the roller 51 to roll on the transportation platform 41, the spacing component 2 limits the roller 51 in the accommodating area 6, and the transportation of the carrier 5 on the transportation platform 41 is realized.

In this embodiment, the switch base 21 is provided with a rotation slot 211 for plugging the top of the switch board 22, and two rotation holes 212 for communicating the two sidewalls of the rotation slot 211 with the outside, and the top of the switch board 22 is provided with a rotation shaft 221 with two ends respectively plugging the two rotation holes 212, as shown in fig. 4. The switch base 21 is provided with a rotation groove 211 and a rotation hole 212, the two rotation holes 212 are used for communicating the two side walls of the rotation groove 211 with the outside, a rotating shaft 221 is arranged at the top of the switch plate 22, and when the top of the switch plate 22 is inserted into the rotation groove 211, the two ends of the rotating shaft 221 are respectively inserted into the two rotation holes 212, so that the switch plate 22 is rotationally connected with the switch base 21. When the shutter plate 22 rotates upward or downward, the rotation shaft 221 at the top of the shutter plate 22 is used as a center, so that the shutter plate 22 can open or close the carrying passage 7 below the shutter base 21.

In this embodiment, the switch board 22 is further provided with an elastic buffer board 222, and after the switch board 22 rotates on the switch base 21 upwards by a certain angle, the elastic buffer board 222 abuts against the switch base 21, and the specific effect is shown in fig. 4 and 5. The elastic buffer plate 222 is arranged on the switch plate 22, when the switch plate 22 is abutted to the roller 51, and the roller 51 just can enter the accommodating area 6 from the lower side of the switch plate 22 through the carrying channel 7 after the switch plate 22 rotates upwards by a certain angle with the rotary shaft 221 as the center of a circle, the elastic buffer plate 222 is abutted to the switch base 21, so that the elastic buffer plate 222 can limit the upward rotating angle of the switch plate 22, reduce the collision force between the switch plate 22 and the switch base 21, and prolong the service life of the limiting assembly 2.

In this embodiment, the switch board 22 is further provided with a limiting boss 223, and after the switch board 22 rotates downward on the switch base 21 by a certain angle, the limiting boss 223 abuts against the switch base 21, and the specific effect is shown in fig. 4 and 5. The switch plate 22 is further provided with a limit boss 223, when the switch plate 22 vertically extends downwards on the switch base 21, the limit boss 223 is abutted with the switch base 21, so that the switch plate 22 can only rotate upwards towards the direction of the pushing assembly 3 by taking the rotating shaft 221 as the center of a circle, but cannot rotate reversely, and therefore when the roller 51 enters the carrying channel 7 from one side of the switch base 21 far away from the pushing assembly 3, the switch plate 22 can be pushed to rotate upwards towards the direction of the pushing assembly 3 by taking the rotating shaft 221 as the center of a circle, the carrying channel 7 is opened, and the roller 51 enters the accommodating area 6 through the carrying channel 7. When the roller 51 enters the accommodating area 6, the switch plate 22 rotates downward with the rotation shaft 221 as a center of circle under the action of gravity to restore to the state of extending vertically downward on the switch base 21, and the limit boss 223 abuts against the switch base 21 at this time, so that the switch plate 22 cannot rotate in the same direction any more, and therefore, when the pushing component 3 pushes the roller 51 to roll in the accommodating area 6, the switch plate 22 limits the roller 51 in the accommodating area 6, so that the carrier 5 always maintains the synchronous effect with the pushing component 3 in the running process.

In this embodiment, the roller 51 includes two wheels riding on two sides of the sliding rib 42, and a roller connecting the axes of the two wheels, and the end of the switch base 21 near the roller 51 entering the carrying channel 7 is pointed, as shown in fig. 1 and 3. In the present utility model, the roller 51 includes two wheels and a roller connecting the axes of the two wheels, and when the roller 51 is located on the transportation platform 41, the height of the roller is greater than the thickness of the sliding rib 42, so that when the two wheels ride on two sides of the sliding rib 42, the sliding rib 42 can limit the two wheels without obstructing the roller.

When the roller 51 is located on the transport platform 41, the switch base 21 extends to a height lower than the height of the wheels and higher than the height of the rollers at the lower end of the driving chain 1, so that the structure of the device is more compact. When the roller 51 passes through the carrying passage 7, the bottom of the switch base 21 passes between the two wheels, so in the present utility model, the end of the switch base 21, which is close to the roller 51 and enters the carrying passage 7, is set to be a tip, thereby making the passage of the roller 51 through the carrying passage 7 smoother.

In this embodiment, the pushing component 3 includes a pushing block 31 fixed on the driving chain 1, and an arc surface 311 matched with the shape of the roller 51 is disposed on one side of the pushing block 31 close to the limiting component 2, and the specific effect is shown in fig. 1 and 6. The pushing assembly 3 comprises a pushing block 31, wherein the top of the pushing block 31 is fixed at the lower end of the driving chain 1, and the bottom of the pushing block extends downwards to the driving chain 1, so that the pushing block 31 and the switch base 21 oppositely arranged on the driving chain 1 are enclosed into a containing area 6 for containing the roller 51. The push block 31 is provided with the arc-shaped surface 311 matched with the shape of the roller 51 on one side close to the switch base 21, so that the accommodating area 6 can accommodate the roller 51 better, and the contact area between the push block 31 and the roller 51 is enlarged when the push block 31 pushes the roller 51 to roll on the transport platform 41, so that the driving effect of the push assembly 3 on the carrier 5 is better, and the carrier 5 runs on the transport platform 41 more stably.

In this embodiment, the pushing assembly 3 further includes a pushing bar 32 disposed at one side of the pushing block 31, where the pushing bar 32 is disposed laterally at one side of the pushing block 31, so as to push the carrier 5 to separate the tracks and go out of the station, as shown in fig. 1 and 6. Since the switch plate 22 extends vertically downward on the switch base 21 and cannot move away from the pushing assembly 3 when the roller 51 is located in the accommodating area 6, the roller 51 cannot move axially out of the accommodating area 6 when the carrier 5 is transported to the next process, and only the roller 51 can move laterally out of the accommodating area 6 by being laterally split by being arcuately connected with the transporting platform 41. The lateral pushing bar 32 is disposed at one side of the pushing block 31, so that the power is provided to the roller 51 when the roller 51 transits from the transportation platform 41 to the lateral split rail, so that the roller 51 moves onto the lateral split rail smoothly, and transportation of the carrier 5 is completed.

The above description may be implemented alone or in various combinations and these modifications are within the scope of the present utility model.
