Detailed Description

Referring to fig. 1 and 2, the lifting unit of the conveyor includes a frame 10, a power module mounted on the frame, and lifting belts connected to the power module, the loading unit is connected to the bottom ends of the lifting belts, the number of the lifting belts is three, and the three lifting belts form a triangle by connecting lines of orthographic projections on a horizontal plane.

The bottom ends of the three lifting belts are connected with a loading unit, and the loading unit is used for loading articles.

The orthographic projection of the drooping part of the three lifting belts on the horizontal plane is three points, and the three points are sequentially connected on the horizontal plane to form a triangle.

And one power module drives the three lifting belts to synchronously lift, so that the stable lifting of the loading unit is realized. Wherein, the power module drives the lifting belt to lift in a winding mode.

The power module comprises a motor 21 arranged on the frame 10, a main shaft driven by the motor, a first winding disc 22 arranged at the front end of the main shaft, and a second winding disc 23 arranged at the rear end of the main shaft; the first winding disc is provided with a first winding structure 221 and a second winding structure 222 which are arranged in parallel, a first lifting belt 31 of the three lifting belts is wound in the first winding structure, a second lifting belt 32 is wound in the second winding structure, and a third lifting belt 33 is wound on the second winding disc; the first belt passes through the first follower wheel 41 and then hangs down at the front left of the frame, the second belt passes through the second follower wheel 42 and then hangs down at the front right of the frame, and the third belt passes through the third follower wheel 43 and then hangs down at the rear of the frame. The above-mentioned design of power module and lift area realizes: firstly, three lifting belts synchronously lift; and secondly, connecting lines of orthographic projections of the three lifting belts on the horizontal plane form a triangle.

A first pair of guide wheels 44 are arranged on the bracket of the first follow-up wheel, and guide the drooping part of the first lifting belt 31 by the first pair of guide wheels; a second pair of guide wheels 45 is arranged on the bracket of the second follow-up wheel, and the second pair of guide wheels guides the drooping part of the second lifting belt 32; a third pair of guide wheels 46 is provided on the support of the third follower wheel, and guides the drooping portion of the third belt 33. Therefore, the three lifting belts can be ensured to vertically lift, and the lifting stability of the loading unit is improved; and can also play a role in limiting the shaking (left-right shaking or front-back shaking) of the loading unit in the operation process of the conveyer.

The frame 10 is provided with a cover plate 50, which is provided with a coupling flange 51 that can be coupled to a drive unit of the conveyor. The cover plate is laid on the upper surface of the rack, namely the area of the cover plate is equivalent to that of the upper surface of the rack, and the connection stability of the driving unit and the lifting unit can be improved.

The general shaft comprises a first shaft 25 and a second shaft 26 connected by a coupling 24, which are pivoted on two bearing blocks 27, respectively. The two bearing blocks support a shaft, and the shaft has better stability; the total shaft is long, and the two shafts are connected through the coupler, so that the bending deformation of the total shaft can be avoided, and the form and position errors between the two shafts can be absorbed.

As an improvement, a sensor support 11 and a buffer piece 12 which extend downwards are arranged on the frame 10, a sensor is arranged on the sensor support, the loading unit is driven by the lifting unit to ascend, when the top of an article on the loading unit is equal to the height of the sensor, the sensor senses and transmits a signal to the main control unit, and the main control unit controls the motor 21 to stop the operation. The bolster can cushion the top of article, avoids the striking.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
