Description

Technical Field

[0001] The present invention relates to the field of conveying equipment, and in particular to a chain conveying system and an IBC barrel conveying method. Background Art

[0002] The existing chain conveyor mechanism is a double chain conveyor that moves side by side. The double chains have the same conveying length and are aligned in the horizontal direction. Figure 1 As shown, the bottom of the IBC barrel structure is a tubular column structure. When it is transported by a chain conveyor mechanism, since the sprocket diameter is usually large, the connection parts between the chain conveyor mechanisms form a V-shaped depression (such as Figure 2-3 As shown in the figure, when an IBC is conveyed along the chain conveyor mechanism to the connection point, the bottom pipe string 10 will fall into the V-shaped depression, causing a jam or collision, which can cause the pipe string structure to deform. Especially when the IBC is fully filled with material, the total weight can reach over one ton, and the entire IBC may even get stuck at the connection point, disrupting the entire conveyor line. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a chain conveyor system and an IBC barrel conveying method to solve the problem of jamming or collision at the connection part of the chain conveyor mechanism when conveying IBC barrels or other goods with non-flat bottoms.

[0006] The first conveying chain, the second conveying chain and the third conveying chain of each chain conveying unit are driven by the same motor for synchronous conveying, and the conveying speeds of two adjacent chain conveying units are equal;

[0007] A first connecting portion is formed between the first conveyor chains of two adjacent chain conveyor units, a second connecting portion is formed between the second conveyor chains, and a third connecting portion is formed between the third conveyor chains; a gap of 1-10 mm is maintained between the two conveyor chains at each connecting portion;

[0008] Among them, along the conveying direction of the chain conveyor system, the third connecting part is located at a position further back than the first connecting part and the second connecting part, so that the first connecting part, the second connecting part and the third connecting part form a ">" shape; or, the third connecting part is located at a position further forward than the first connecting part and the second connecting part, so that the first connecting part, the second connecting part and the third connecting part form a "<" shape.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 4-7 As shown, the present invention provides a chain conveyor system, comprising two or more chain conveyor units 20, wherein the chain conveyor units 20 are connected end to end to form a conveyor line, which is generally a straight conveyor line;

[0033] Each of the chain conveyor units 20 includes a first conveyor chain 21 and a second conveyor chain 22 arranged in parallel and at the same height. At least one third conveyor chain 23 is provided between the first conveyor chain 21 and the second conveyor chain 22. The third conveyor chain 23 is parallel to the first conveyor chain 21 and has the same height as the first conveyor chain 21. The first conveyor chain 21, the second conveyor chain 22, and the third conveyor chain 23 are located at the same height, thereby forming a conveying plane. At the same time, it is preferred that the third conveyor chain 23 is placed in the middle position between the first conveyor chain 21 and the second conveyor chain 22, so that the third conveyor chain 23 can be supported at the center position of the IBC barrel.

[0034] The first conveying chain, the second conveying chain and the third conveying chain of each chain conveying unit are driven by the same motor for synchronous conveying, and the conveying speeds of two adjacent chain conveying units are equal;

[0035] A first connecting portion 25 is formed between the first conveyor chains 21 of two adjacent chain conveyor units 20, a second connecting portion 26 is formed between the second conveyor chains 22, and a third connecting portion 27 is formed between the third conveyor chains 23; a gap of 1-10 mm is maintained between the two conveyor chains at each connecting portion;

[0036] Among them, Figure 6 As shown, along the conveying direction of the chain conveyor system, the third connecting part 27 is located at a position further back than the first connecting part 25 and the second connecting part 26, so that the first connecting part 25, the second connecting part 26 and the third connecting part 27 form a “>” shape; or, the third connecting part is located at a position further forward than the first connecting part and the second connecting part, so that the first connecting part, the second connecting part and the third connecting part form a “<” shape.

[0037] Optionally, in the conveying direction, the distance between the third connecting part 27 and the first connecting part 25 and the second connecting part 26 is greater than the radius of the sprocket of the connecting part, so that when the pipe string 10 of the IBC barrel is located in the middle of one of the connecting parts, the other connecting parts can provide support for the pipe string 10 at their positions due to the misalignment exceeding the radius of the sprocket, thereby making the conveying smoother at the connecting position.

[0038] Optionally, the first conveying chain 21 , the second conveying chain 22 , and the third conveying chain 23 are driven by the same motor 24 , thereby saving energy consumption, reducing manufacturing costs, and achieving better transmission consistency.

[0039] Optionally, the motor 24 drives the driving shaft 28 to rotate via a driving sprocket set, and the driving sprockets of the first conveying chain 21 , the second conveying chain 22 , and the third conveying chain 23 are respectively mounted on the driving shaft 28 .

[0040] Optionally, the first conveying chain 21, the second conveying chain 22, and the third conveying chain 23 are of the same length, so that when the two chain conveying units 20 are connected, the conveying length of each conveying chain can be ensured to be the same, and the connection effect is also better.

[0041] Optionally, there is one third conveyor chain 23 , and the distance between the third conveyor chain 23 and the first conveyor chain 21 and the second conveyor chain 22 is equal, so that the third conveyor chain 23 is located in the middle and is just supported at the bottom center of the IBC barrel.

[0042] Optionally, there are two third conveyor chains 23, and the two third conveyor chains 23 are distributed on both sides of the center line of the chain conveyor unit. Usually, the two third conveyor chains 23 can be arranged symmetrically relative to the center line, but the connecting parts of the two third conveyor chains 23 can be misaligned, and when the two third conveyor chains 23 are misaligned, the transmission stability of the conveyor line can be better.

[0043] Optionally, the first connecting portion 25 and the second connecting portion 26 are not aligned in the conveying direction, so that the pipe column 10 at the bottom of the IBC barrel will not contact the first connecting portion 25 and the second connecting portion 26 at the same time during the conveying process, thereby stabilizing the transmission process and avoiding jamming.

[0044] Optionally, in the conveying direction, the distance between the first connecting portion 25 and the second connecting portion 26 is greater than the radius of the sprocket at the connecting portion, so as to better avoid V-shaped depressions, making the transmission more stable and preventing jamming.

[0045] Optionally, a non-powered transition roller group 30 or a transition pulley group is provided on the inner or outer side of the first connecting part 25 and the second connecting part 26. The height of the transition roller group 30 and the transition pulley group is the same as the height of the first conveyor chain, which can assist the chain conveyor unit 20 in conveying the IBC barrels.

[0046] The chain conveyor system provided by the present invention adds a third conveyor chain to the chain conveyor system and arranges the third conveyor chain in a staggered manner with the first conveyor chain and the second conveyor chain. As a result, when conveying goods with uneven bottoms such as IBC barrels, the chain conveyor system can overcome jams or collisions caused by V-shaped depressions at the connection parts, thereby ensuring smooth conveying.

[0047] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
