Technical Field

The invention relates to the technical field of logistics conveying devices, in particular to a deflection ball conveying mechanism.

Background

The automatic sorting system is an important branch of a material handling system, and is widely applied to production logistics systems, logistics distribution centers or airport baggage conveying centers and the like in various industries. The automatic sorting machine mainly comprises a part supply device, a conveying device, a control system, a sorting device, a sorting road junction and the like, and is one of key devices for automatically sorting and arranging articles. Divide according to sorter's structure, common automatic sorting machine's mainly include types such as slider sorting machine, runner (or called bevel pulley) letter sorting, cross area letter sorting, board-like sorting machine, swing arm formula sorting machine, the formula sorting machine that floats, tray formula sorting machine, suspension type sorting machine.

Disclosure of Invention

The invention aims to: the invention provides a deflection ball conveying mechanism, aiming at solving the technical problems that a deflection wheel in the existing logistics sorting device is limited in the range of being suitable for goods, and the deflection wheel can only deflect integrally within the range of plus or minus 45 degrees along the conveying direction, so that the use scene is limited.

The invention specifically adopts the following technical scheme for realizing the purpose:

the utility model provides a ball conveying mechanism deflects, includes deflection mechanism and actuating mechanism, and deflection mechanism includes the support frame, and swing joint has the ball that deflects on the support frame, has the clearance between ball that deflects and the support frame bottom, and the support frame bottom is connected with the swing arm, and the swing arm is used for driving the whole deflection of ball that deflects, and deflection angle is 0-90, and actuating mechanism includes the transmission shaft, and the cover is equipped with the cone pulley with ball contact that deflects all the time on the transmission shaft, and the cone pulley is used for driving the ball rotation that deflects.

Furthermore, the transmission shaft is a square shaft, the driving mechanism further comprises a fixing ring fixedly sleeved on the transmission shaft, the fixing ring is connected with a tensioning spring wound on the transmission shaft, the other end of the tensioning spring is connected with a conical wheel, and the conical wheel is movably sleeved on the transmission shaft.

Furthermore, one end of the transmission shaft is connected with a driving shaft, and a first bearing is arranged on the driving shaft.

Furthermore, both ends of the deflection ball are connected with movable shafts, and both ends of the support frame are provided with second bearings matched with the corresponding movable shafts.

Furthermore, the bottom of the support frame is connected with a rotating shaft, a support bearing is arranged on the rotating shaft, and a cushion pad is arranged between the support bearing and the bottom of the support frame.

Furthermore, a plurality of circles of annular grooves are formed in the deflection ball along the conveying direction of the deflection ball.

The working principle is as follows: the driving shaft is powered to make the driving mechanism start to rotate, the cone wheel on the transmission shaft rotates along with the driving shaft, the friction force generated during rotation drives the deflection ball to rotate, so that the deflection ball drives a tray (not shown in the figure) bearing goods to be conveyed forwards by utilizing the friction force, when the goods conveying direction needs to be changed, the swing arm is powered to horizontally rotate, so that the whole deflection mechanism starts to integrally deflect by taking the rotating shaft as a rotating center until the deflection ball deflects to a proper angle, then the tray deflects by a certain angle along with the rotation of the deflection ball and moves towards the conveying direction after deflection under the action of the rotation of the deflection ball, and the shunting effect of the goods on the conveying line is finished.

The invention has the following beneficial effects:

1. the invention connects the deflection ball on the supporting frame, which can rotate freely, and uses friction force to drive the deflection ball to rotate, because the cone wheel and the deflection ball are always contacted, which is not affected by the weight of goods, it can be used in the transportation of various goods, and the swing arm can drive the whole deflection mechanism to rotate when deflecting horizontally, and creates necessary condition for the deflection ball to deflect to 90 degrees, improves the deflection angle, the deflection direction is reliable, and it can be used in the use scene of various goods shunting with large angle.

2. When the cone wheel or the deflection ball is abraded to a certain extent, the cone wheel is always in abutting contact with the deflection ball under the action of the tension spring, force transmission is uniform, and transmission reliability is guaranteed.

3. The annular grooves are formed in the deflection ball, so that the friction force between the deflection ball and the goods tray is increased, and the transmission force is improved.
