Background
At present, the following four conveying modes are mostly adopted by the existing elevator equipment: 1. ball screw elevator: the motor is used for driving the ball screw to repeatedly transport goods up and down; 2. chain or wire rope elevator: the motor is used for driving the chain or the steel wire rope to lift the lift car to transport goods repeatedly up and down; 3. belt type hoister: the goods are circularly conveyed upwards by utilizing a slope type belt; 4. a reciprocating type elevator: and the chain is used for driving the bridge plate to transport cargos up and down in a reciprocating manner.
However, the above-mentioned conveying methods have various drawbacks. The 1 st transport mode utilizes ball screw transportation although steady, but very slow, great influence production efficiency, to requiring highly great lifting machine moreover, the degree of difficulty is very big, hardly realizes probably basically. The 2 nd conveying mode utilizes a chain type or a steel wire rope type lifting machine to transport goods, and has the defect that when the goods with higher transport height are transported, the purpose of transporting one goods every 3 seconds is basically impossible, the transportation efficiency is influenced, and the transported goods are not stable enough. The 3 rd way uses a ramp belt to transfer the goods upwards in a circulating manner, the slope of the ramp cannot be too large, and for the occasion of large transfer height, the way occupies a large amount of transverse space. Meanwhile, the transportation speed cannot be too fast in order to ensure safety. The 4 th conveying mode utilizes a reciprocating type elevator to convey goods, so that the efficiency is very low, the conveying safety cannot be guaranteed, and the stability is poor.

Furthermore, the power source of belt transfer chain is servo motor, and servo motor's positioning accuracy is high, can make the hanging flower basket stop in appointed place.
Further, the conveying line may be a belt conveying line or a chain conveying line.
The utility model has the advantages that:
the high-efficiency goods elevator of the utility model has the advantages that the hanging basket is recycled, the hanging basket rises and falls linearly, the efficiency is greatly improved, the goods can be transported at high speed for a long time, and the average speed can reach 3 seconds; the fixing connecting rod is clamped through the clamping device when the goods are taken, so that the stability of the hanging basket is ensured when the materials are taken; the hanging basket naturally droops along with gravity, and is always kept horizontal with the ground, and the transportation process is steady, and the reliability is high.

Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As described in the background art, currently, the widely used hoists are ball screw hoists, chain hoists or wire rope hoists, belt hoists, and reciprocating hoists, but these hoists all have various defects and cannot satisfy both the conveying efficiency and the running stability.
To solve this technical problem, the present invention provides a high-efficiency goods elevator, see fig. 1-2, comprising a vertically arranged conveyor line and a plurality of baskets 300. The conveying line includes, but is not limited to, a belt conveying line 200, a chain conveying line. In this embodiment, the conveyor line is a belt conveyor line 200.
A mounting block 100 is provided at both the top and bottom of the belt conveyor line 200 for mounting a driving source and a pulley 220. A bearing block 500 is fixedly arranged on the belt 210 of the belt conveyor line 200 at a certain interval.
Referring to fig. 3, a horizontal connecting rod 400 is fixedly connected to the top of each basket, the connecting rod 400 can be fixedly connected to the basket 300 in various ways, and in this embodiment, the connecting rod 400 is welded to the basket 300. The connecting rod 400 is inserted into the bearing block 500 and is rotatably connected to the bearing block 500 through a pair of bearings. Therefore, the hanging basket 300 naturally droops along with gravity and is always kept horizontal with the ground, and the stability in the transportation process is ensured.
The hoist further includes a plurality of clamping devices provided on the conveying path of the belt conveyor line 200 for clamping the other end portion of the fixed link 400, which is extended. When the belt conveyor line 200 drives the hanging basket 300 to a specified place for picking and sorting, the clamping device starts to clamp the other end of the fixed connecting rod 400, so that the hanging basket 300 is stable, and the goods in the hanging basket 300 are prevented from shaking left and right.
In the present invention, the other end of the connecting rod 400 preferably has a prism shape, and the clamping device has a claw engaged with the prism shape. The end of the connecting rod 400 is arranged to be prismatic, so that the connecting rod can be quickly, conveniently and stably fixedly matched with the clamping jaw in the same shape. In this embodiment, the other end of the link 400 is in the shape of a hexagonal prism 410. The clamping device is a claw type cylinder.
In this embodiment, each clamping device is configured with a mechanical arm, which can realize the functions of automatically replenishing goods into the hanging basket 300, and automatically picking up and sorting goods.
The figures of the present invention show only two clamping devices (respectively at the bottom and top). It will be appreciated that in other embodiments, the gripping means may be provided in plurality, to meet the requirements of transporting goods to different locations. Of course, a mounting frame 100 is required for each delivery site to mount the clamping device, the robot arm, and the like.
In this embodiment, the driving source of the belt conveyor line 200 is a servo motor, and the positioning accuracy of the servo motor is high, so that the hanging basket 300 can be stopped at a specified place.
In this embodiment, two-dimensional codes are attached to the baskets 300, and two code scanning devices are arranged on the conveying path of the belt conveyor line 200 and are respectively used for recording the position information and the goods information of the baskets 300 filled with goods and the position information of empty baskets 300. By arranging the code scanning mechanism, the warehouse location management of each hanging basket 300 is realized, and the empty hanging basket 300 can be effectively taken and reasonably sent to a destination.
The working flow of the hoister in the embodiment is as follows:
firstly, a mechanical arm grabs and puts goods on the hanging basket 300, and during the period, the claw type air cylinder starts to work and clamps the hexagonal prism 410 part at the end part of the connecting rod 400 to prevent the goods from shaking left and right; after the goods are placed, the air cylinder is loosened, the servo motor drives the belt to convey upwards, the belt reaches a code scanning area to scan codes, and the state information of the hanging basket 300 and the goods information are recorded; then the belt drives the hanging basket 300 to reach the appointed floor, at the moment, the claw type cylinder clamps the hexagonal prism part at the end part of the connecting rod 400, and the mechanical arm is used for taking out the goods; and finally, loosening the cylinder, continuously walking by the belt, scanning the code again to record the position information of the empty hanging basket 300, and continuously taking goods downwards repeatedly.
