Description

Technical Field

[0001] The utility model belongs to the field of lifting conveyors, and in particular relates to a lifting conveyor with adjustable height. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are acid-resistant, alkali-resistant, oil-resistant, non-toxic and odorless. They can be used to hold food, etc. They are easy to clean, and parts turnover is convenient, neatly stacked, and easy to manage. They are suitable for transportation, distribution, storage, circulation processing and other links in factory logistics. Turnover boxes can be used in conjunction with a variety of logistics containers and workstation equipment, and can be used in various warehouses, production sites and other occasions. Today, when logistics management is increasingly valued by the majority of enterprises, turnover boxes help to complete the universal and integrated management of logistics containers, and are essential for production and circulation enterprises to carry out modern logistics management. Turnover boxes and turnover box conveying devices are widely used in the production process of workpieces. However, since it is often necessary to transport the turnover boxes from a lower position to a higher position during the transportation of the turnover boxes, the more primitive method is to use manual handling to achieve the transfer, but this method is inefficient, cannot guarantee safety, and is labor-intensive and time-consuming.

DETAILED DESCRIPTION

[0018] The present invention is further described below through specific implementation methods.

[0019] Reference Figures 1 to 3 As shown, a height-adjustable lifting conveyor includes a frame 1, a lifting frame 2, two guide mechanisms 3, two conveying mechanisms 4 and a driving mechanism 5.

[0020] The lifting frame 2 is movably arranged in the frame 1, and includes a lifting frame body 21, a positioning frame 22 arranged in the middle of the lifting frame body 21, and two lifting arms 23 relatively arranged on both sides of the lifting frame body 21. A conveying station 24 is formed between the positioning frame 22 and the relative lifting arms 23. When the box is conveyed, it is transferred to the conveying station 24 and conveyed to a designated higher position through the lifting frame 2 that can be moved up and down.

[0021] The two guide mechanisms 3 are respectively arranged between the frame 1 and the relative lifting arm 23. Specifically, the guide mechanism 3 includes a guide block 31 arranged on the lifting arm 23 and relative to the positioning frame 22 to guide the box to enter the conveying station 24, a first sensor 32 arranged on the frame 1 at the front end of the guide block 31 for detecting whether the box enters the conveying station 24, a second sensor 33 arranged at the rear end of the guide block 31 for detecting whether the box reaches the specified position, a guide groove 34 arranged on the frame 1 and relative to the lifting arm 23, and a first guide wheel 35 and a second guide wheel 36 rotatably arranged on the lifting arm 23 and cooperating with the guide groove 34. 36. Further, the axis of the first guide wheel 35 is arranged perpendicular to the conveying direction of the box, and the axis of the second guide wheel 36 is arranged perpendicular to the axis of the first guide wheel 35, that is, the axis of the second guide wheel 36 is arranged parallel to the conveying direction of the box, and the first guide wheel 35 and the second guide wheel 36 are respectively matched with the guide groove 34 to ensure the stability of the lifting frame 2 during the lifting process; further, two first guide wheels 35 and two second guide wheels 36 are provided, and the two second guide wheels 36 are located between the two first guide wheels 35; further, the first sensor 32 and the second sensor 33 adopt counter-radiation sensors.

[0022] The guide block 31 includes a first guide section 311 and a first positioning section 312 which are sequentially arranged along the conveying direction of the box body, and the first guide section 311 is arranged to be inclined inward along the conveying direction of the box body. Correspondingly, the opposite surfaces of the positioning frame 22 and the guide block 31 are formed with a second guide section 221 and a second positioning section 222 which are respectively opposite to the first guide section 311 and the first positioning section 312. By respectively arranging the first guide section 311 and the second guide section 221 on the guide block 31 and the positioning frame 22, the box body can smoothly enter the corresponding conveying station 24, thereby ensuring the smooth conveying of the box body.

[0023] The two conveying mechanisms 4 are respectively arranged on the lifting frame body 21 and located on the corresponding conveying station 24, and are used to receive the conveyed box, including a conveying frame 41 arranged on the lifting frame 2, a conveyor belt 42 rotatably arranged on the conveying frame 41, and a conveying motor 43 arranged on the lifting frame 2 and connected to and driving the conveyor belt 42 to rotate. When the box is transported, when the first sensor 32 detects that the box enters the conveying station 24 from the previous conveyor, the conveying motor 43 controls the conveyor belt 42 to rotate to receive the entered box. When the second sensor 33 detects that the box is transferred to the specified position, the conveying motor 43 controls the conveyor belt 42 to stop transmission, and then controls the lifting frame 2 to rise and fall to the specified height. Then the conveying motor 43 controls the conveyor belt 42 to continue to rotate, so as to smoothly convey the box to the next equipment for subsequent work.

[0024] The driving mechanism 5 is arranged on the frame 1, connected to and drives the lifting frame 2 to move up and down, and includes a driving motor 51 arranged on the frame 1, a rotating capstan 52 connected to the output end of the driving motor 51, two lifting capstan belts 53 relatively arranged at both ends of the rotating capstan 52 and respectively connected to the two lifting arms 23, and a tensioning mechanism 54 relatively arranged on the frame 1 for tensioning the relative lifting capstan belts 53; specifically, the tensioning mechanism 54 includes a tensioning seat 541 arranged on the frame 1 at one side of the rotating capstan 52, a transition wheel 542 rotatably arranged on the tensioning seat 541, a swinging frame 543 swingably arranged on the tensioning seat 541, A tensioning wheel 544 is arranged on the swing frame 543 opposite to the transition wheel 542, and a tensioning torsion spring 545 is arranged between the swing frame 543 and the tensioning seat 541 to make the tensioning wheel 544 close to the transition wheel 542, wherein one end of the lifting capstan belt 53 is connected to the rotating capstan 52 and the other end bypasses the transition wheel 542 and extends downward to be connected to the relative lifting arm 23. The tensioning wheel 544 is closely attached to the lifting capstan belt 53 on the transition wheel 542 under the action of the tensioning torsion spring 545, and the tensioning force between the lifting capstan belt 53 and the lifting frame 2 is ensured by limiting the structure of the tensioning mechanism 54, so that the box body can be stably lifted and lowered to the specified position along with the lifting frame 2.

[0025] The present application limits the structure of the lifting conveyor and sets a tensioning mechanism 54 between the lifting frame 2 that can be moved up and down and the driving motor 51 to ensure the tensioning force of the lifting capstan belt 53, so that the box can be stably lifted and lowered to the specified position along with the lifting frame 2. The overall structure is simple and the production cost is low, which can meet the transportation requirements of the box at any conveying height.

[0026] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
