Detailed ways

The present invention will be further described below with reference to the embodiments in the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , the traction mechanism of the suspended chain conveyor includes a transport track 1 , a traction frame 2 and a trolley 3 . The conveying track 1 includes a guide rail 13, a suspension chain 11 and a guide rod 12 for arranging the trolley 3. The suspension chain 11 is located in the guide rail 13 and moves along the guide rail 13. The traction frame 2 is connected with the suspension chain 11 and moves with the suspension chain 11. The traction frame 2 is in contact with the trolley 3 and drives the trolley 3 to move along the guide rod 12 . In this traction mechanism, the traction frame 2 drives the trolley 3 to move, and the goods are arranged on the trolley 3 and do not directly interact with the traction frame 2. Therefore, the shapes and placement methods of the goods are more diverse. A single trolley 3 or between adjacent trolleys 3 Multiple goods can be set, and the conveying efficiency is high. Compared with the traditional suspension chain conveying mechanism, the sorting method that can be adopted by the traction mechanism is more flexible, and is no longer limited to the common drop sorting, and horizontal sorting can be realized by changing the connection of the guide rod 12 . The traction frame 2 is connected to the suspension chain 11, and the number of the trolleys 3 can be increased according to the needs. The traction frame 2 arranged on the circulating suspension chain 11 can push the trolley 3 to move in contact with the trolley 3 during the moving process, which greatly improves the conveying efficiency. with flexibility.

As shown in FIG. 2 and FIG. 3 , the traction frame 2 includes a connecting member 21 and a pulling member 22 . The pulling member 22 is hingedly arranged on the connecting member 21 . The traction surface 221 is disposed on the traction member 22, which is a vertical surface or an approximately vertical surface. The connecting piece 21 is connected to the suspension chain 11, and after the first inclined surface 222 is in contact with the trolley 3 placed on the guide rod 12, the trolley 3 generates a load perpendicular to the first inclined surface 222 to the traction piece 22, and the moment generated by the load makes the traction piece 22 is twisted relative to the connecting piece 21 , the traction frame 2 continues to advance and travels to the upper side of the trolley 3 , so that the traction surface 221 abuts against the trolley 3 to push the trolley 3 to move. The upper end of the traction member 22 is provided with a slot in the middle, and the lower end of the connecting member 21 is embedded in the slot. The upper end of the traction member 22 is provided with a pin hole, and the two are hingedly connected by a pin.

The pulling member 22 is hingedly arranged on the connecting member 21 through the hinge shaft. When the pulling member 22 rotates relative to the connecting member 21, the limiting shaft 225 moves along the arc-shaped limiting groove 211, so as to ensure the stability of the conveying track for the pulling member 22 to rotate, and at the same time The rotation of the traction member 22 is limited.

A limiting surface 223 is provided between the traction surface 221 and the first inclined surface 222 , and the limiting surface 223 is opposite to the traction surface 221 and located on both sides of the trolley 3 respectively. The traction surface 221 is a vertical surface or a surface inclined from top to bottom in the downstream direction of the movement of the traction member 22 to ensure that the trolley 3 can be stably moved. The inclined surface is inclined in direction, which avoids the situation that the cart 3 moves away from the traction surface 221 under the action of inertia. The lower end of the traction surface 221 is lower than the lower end of the limiting surface 223 . After the trolley 3 pushes against the first inclined surface 222 and pushes the traction member 22 to rotate, it is ensured that the traction member 22 can smoothly hook the trolley 3 during the rotation process.

The upper end of the trolley 3 is provided with an arc-shaped surface 31 toward the downstream side in the moving direction of the traction frame 2 . The contact area of the arc-shaped surface 31 and the second inclined surface 224 or the limiting surface 223 is small, and the frictional force is small, so the trolley 3 and the traction member 22 are more smoothly in the process of cooperation. A second inclined surface 224 is provided on the traction member 22 toward the upstream of the moving direction of the traction frame 2 . When the initial speed of the trolley 3 placed on the guide rod 12 is greater than the moving speed of the traction frame 2, the trolley 3 abuts against the second lower surface and pushes the traction member 22 to rotate, that is, the trolley 3 lifts the traction member 22 to move to the front end of the traction surface 221. And cooperate with the traction surface 221 .

The trolley 3 is provided with a stepped structure 32 opposite to the traction surface 221 . The stepped structure 32 includes a bottom surface 321 located on the lower side of the traction surface 221 and a side surface 322 in contact with the traction surface 221 . One end of the traction surface 221 of the traction member 22 is embedded on the stepped structure 32 , which further ensures the stability of the driving connection between the traction member 22 and the trolley 3 . The trolley 3 includes a traction part 33 suspended on the guide rod 12 . A roller 331 is provided between the traction part 33 and the guide rod 12 . The rollers 331 are shaped to fit with the guide rod 12 , so as to reduce friction and avoid the deviation of the trolley 3 along the radial direction of the guide rod 12 . The guide rod 12 is a cylindrical rod, the roller 331 is provided with an annular groove, and the guide rod 12 is embedded in the groove. The number of traction parts 33 on the trolley 3 is at least two, and a connecting rod 34 for placing goods is provided between adjacent traction parts 33 . The end of the connecting rod 34 is fixed on the lower end of the adjacent trolley 3, and goods, such as clothes hangers, can be hung thereon. The length of the connecting rod 34 can be flexibly changed according to needs, and can be adapted to the situation of different quantities of goods.
