Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a chain plate type storage bin. Background Art

[0002] As the degree of automation in the machining field becomes higher and higher, it is becoming more and more common to set up matching robots next to CNC machine tools to assist in loading and unloading.

[0003] In addition to the robot, the storage and feeding of the workpiece are also extremely important components of the machining process. Automating the storage and feeding of the workpiece can further improve the degree of automation and production efficiency of the entire machining line.

[0004] Existing workpiece storage and feeding often use storage bins. After the workpieces are stacked in the storage bin, a conveyor belt is used to send the workpieces out of the storage bin according to the feeding needs and sent to a robot or other device for feeding.

[0005] However, existing conveyor belts can often only be used for storing and conveying workpieces in a horizontal direction, and cannot realize conveying and storing workpieces with height differences. Utility Model Content

[0006] The utility model aims to solve the above problems in the prior art and proposes a chain plate type storage bin to solve the problem that the existing conveyor belt cannot realize the feeding of workpieces with height difference.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The two sprockets and the two sprockets are connected with each other to form a circle, and the two sprockets are connected with each other to form a circle, and the two sprockets are connected with each other to form a circle.

[0009] In this chain plate type storage bin, the positions of the two sprockets 1 are higher than the positions of the two sprockets 2, and the sprocket 1 is set away from the top of the sprocket 2, that is, a height difference is formed between the sprockets 1 and sprocket 2, and the chain wound around the outside of the sprockets 1 and sprocket 2 is not transported in the vertical direction and the horizontal direction, but transported in a direction inclined relative to the horizontal plane. The raised convex parts on the several guide strips fixed between the two chains can be used to support the workpiece to prevent the workpiece from falling during the chain transportation. Here, the spacing between the several guide strips can be determined according to the size of the workpiece that needs to be transported. The side of the guide strip used to place the workpiece refers to the upper side of the guide strip transported to the upper part of the chain and the lower side of the guide strip transported to the lower part of the chain. In this way, this chain plate type storage bin can realize the feeding of workpieces with height differences, meet the use requirements of different places and environments, and have better applicability.

[0010] In the above-mentioned chain plate type material storage bin, the plurality of material guide strips are flat. The flat and long material guide strips are easier to process and more conducive to the placement of workpieces.

[0011] In the above-mentioned chain plate type storage bin, the two protrusions are arranged near the two ends of the material guide strip. The protrusions arranged near the two ends can be suitable for the arrangement of longer workpieces and can provide relatively stable support.

[0012] In the above-mentioned chain plate type storage bin, the frame includes a main body tilted relative to the horizontal plane and a material receiving section extending in the horizontal direction at both ends of the main body. The tilt of the main body can form a height difference, and the material receiving sections extending horizontally at both ends can facilitate the feeding and storage of workpieces.

[0013] In the above-mentioned chain plate type storage bin, the connection between the main body and the material receiving section is an arc transition, and an arc-shaped anti-drop plate is provided at the arc transition, and the anti-drop plate is fixed to the frame through a connecting plate, and an anti-drop groove for the chain to pass through is formed between the anti-drop plate and the frame. The anti-drop plate is provided at the arc transition, so that an anti-drop groove for limiting the chain is formed between the anti-drop plate and the frame, thereby ensuring stable transportation of the chain.

[0014] Compared with the prior art, the chain plate type storage bin forms a height difference by setting the sprocket one and the sprocket two, and then cooperates with the convex part on the guide bar to limit the workpiece, so as to realize the feeding of workpieces with high and low positions, meet the use requirements of different use places and use environments, and have better applicability.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 As shown, the chain plate type storage bin comprises a frame 1, two sprocket wheels 1 2 and two sprocket wheels 2 3 rotatably connected to the frame 1, two chains 5, and a driving member 4 capable of driving the sprocket wheels 2 3 to rotate circumferentially. In this embodiment, the driving member 4 is a driving motor.

[0019] The frame 1 includes a main body 8 tilted relative to a horizontal plane, a material connection section 9 extending in a horizontal direction at both ends of the main body 8, and a support leg 12 fixed below the main body 8. The connection between the main body 8 and the two material connection sections 9 is an arc transition, and an arc-shaped anti-drop plate 10 is provided at the arc transition. The anti-drop plate 10 is fixed to the frame 1 through a vertically arranged connecting plate 11, and an anti-drop groove is formed between the anti-drop plate 10 and the frame 1. In this embodiment, the anti-drop plate 10 is divided into two groups, each with two, one group is arranged above the connection between the lower end of the main body 8 and the material connection section 9, and the other group is arranged below the connection between the upper end of the main body 8 and the material connection section 9, and the anti-drop plate 10 and the connecting plate 11 are connected as a whole.

[0020] Two sprockets 1 2 are relatively arranged on both sides of the material receiving section 9 located at the upper end of the main body 8, and two sprockets 2 3 are relatively arranged on both sides of the material receiving section 9 located at the lower end of the main body 8. Two chains 5 are arranged on both sides of the frame 1, and each chain 5 is respectively arranged around the sprocket 1 2 and the sprocket 2 3 located on the same side. The driving member 4 can drive the sprocket 2 3 to rotate circumferentially, thereby driving the chain 5 and the sprocket 1 2 to transmit. In this embodiment, the chain 5 is arranged through the anti-slip groove.

[0021] Several guide bars 6, all of which are flat and long, are arranged between the two chains 5. The guide bars 6 are arranged horizontally and the length direction of the guide bars 6 is perpendicular to the conveying direction of the chains 5. The guide bars 6 are evenly distributed between the two chains 5 at equal intervals along the conveying direction of the chains 5, and the two ends of each guide bar 6 are fixed to the two chains 5 respectively.

[0022] Each guide bar 6 has two block-shaped protrusions 7 protruding upward on one side for placing the workpiece, and the two protrusions 7 are spaced apart on the guide bar 6 along the length direction of the guide bar 6. In this embodiment, the two protrusions 7 are arranged near both ends of the guide bar 6.

[0023] In the chain plate type storage bin, a height difference is formed between the sprocket 1 2 and the sprocket 2 3, and the chain 5 wound around the outside of the sprocket 1 2 and the sprocket 2 3 is not transported in the vertical direction and the horizontal direction, but is transported in a direction inclined relative to the horizontal plane. The raised convex parts 7 on the several guide bars 6 fixed between the two chains 5 can be used to support the workpieces to prevent the workpieces from falling during the transportation of the chain 5, so that the workpieces placed on the guide bars 6 can be stacked on the guide bars 6, and can also be transported along the guide bars 6 toward the upper end of the main body 8, so as to realize the transportation of workpieces with a height difference.
