Description

Technical Field

[0001] The present invention relates to the field of conveying equipment, and particularly to a multi-chain conveying line and an IBC barrel conveying method. Background Art

[0002] In the existing chain conveying mechanism, two chains advance side by side, and the conveying lengths of the two chains are the same and horizontally aligned. As Figure 1 shown, the four surrounding sides of the bottom of the IBC barrel structure are of a tubular column structure. When being conveyed by the chain conveying mechanism, due to the relatively large diameter of the sprocket, a V-shaped depression is formed at the connection part between the chain conveying mechanisms (as Figures 2-3 shown). When the IBC barrel is conveyed along the chain conveying mechanism to the connection part, the bottom tubular column 10 will fall into the V-shaped depression, resulting in jamming or collision. Such jamming or collision will cause the deformation of the tubular column structure. Especially when the IBC barrel is filled with materials, the overall weight reaches more than 1 ton, and even the entire IBC barrel will be stagnant at the connection part, causing the entire conveying line to fail to operate normally. Summary of the Invention

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

[0004] To solve the above technical problem, the present invention provides a multi-chain conveying line, including more than two chain conveying units, and the chain conveying units are connected end to end in sequence to form a conveying line;

[0005] Each of the chain conveying units includes a first conveying chain and a second conveying chain which are arranged in parallel and have the same height;

[0006] Between the first conveying chain and the second conveying chain, there are arranged a first auxiliary conveying chain and a second auxiliary conveying chain in parallel, wherein: the distance between the first auxiliary conveying chain and the second conveying chain is less than the distance between the first auxiliary conveying chain and the first conveying chain, and the distance between the second auxiliary conveying chain and the first conveying chain is less than the distance between the second auxiliary conveying chain and the second conveying chain;

[0007] The first conveying chain, the second conveying chain, the first auxiliary conveying chain, and the second auxiliary conveying chain of each chain conveying unit are driven by the same motor to be synchronously conveyed, and the conveying speeds of two adjacent chain conveying units are equal;

[0008] A first connection part is formed between the first conveying chains of two adjacent chain-type conveying units, a second connection part is formed between the second conveying chains, a third connection part is formed between the first auxiliary conveying chains, and a fourth connection part is formed between the second auxiliary conveying chains; a gap of 1-20 mm is maintained between the two conveying chains at each connection part; the projections of the above four connection parts on the conveying direction satisfy any one of the following five conditions:

[0014] The preset distance is the radius of the sprocket at the connection part.

[0015] When the radii of the sprockets at each connection part are different, the radius of the smallest sprocket is used as the preset distance.

[0016] Optionally, the first conveying chain, the second conveying chain, the first auxiliary conveying chain, and the second auxiliary conveying chain are driven by the same motor.

[0017] Optionally, the motor drives the drive shaft to rotate through a drive sprocket set, and the drive sprockets of the first conveyor chain, the second conveyor chain, the first auxiliary conveyor chain, and the second auxiliary conveyor chain are respectively installed on the drive shaft.

[0037] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] As Figures 4-9 shown, the present invention provides a multi-chain conveyor line, including more than two chain conveyor units, and the chain conveyor units are connected end to end in sequence to form a conveyor line;

[0039] Each of the chain conveyor units 20 includes a first conveyor chain 21 and a second conveyor chain 22 that are arranged in parallel and have the same height;

[0040] Between the first conveyor chain 21 and the second conveyor chain 22, there are parallel first auxiliary conveyor chain 23 and second auxiliary conveyor chain 24, where: the distance between the first auxiliary conveyor chain 23 and the second conveyor chain 22 is less than the distance between the first auxiliary conveyor chain 23 and the first conveyor chain 21, and the distance between the second auxiliary conveyor chain 24 and the first conveyor chain 21 is less than the distance between the second auxiliary conveyor chain 24 and the second conveyor chain 22;

[0041] The first conveyor chain, the second conveyor chain, the first auxiliary conveyor chain, and the second auxiliary conveyor chain of each chain conveyor unit are driven by the same motor to be synchronously conveyed, and the conveying speeds of two adjacent chain conveyor units are equal;

[0042] A first connection part 25 is formed between the first conveying chains 21 of two adjacent chain-type conveying units, a second connection part 26 is formed between the second conveying chains 22, a third connection part 27 is formed between the first auxiliary conveying chains 23, and a fourth connection part 28 is formed between the second auxiliary conveying chains 24; a gap of 1 - 20 mm is maintained between the two conveying chains at each connection part; the projections of the above four connection parts in the conveying direction satisfy any one of the following five conditions:

[0043] As Figure 5 shown, the projections of the first connection part 25 and the third connection part 27 are on the same side of the projections of the second connection part 26 and the fourth connection part 28, and the minimum distance between the projections of the first connection part 25 and the third connection part 27 and the projections of the second connection part 26 and the fourth connection part 28 is greater than a preset distance;

[0044] As Figure 6 shown, the projections of the first connection part 25 and the third connection part 27 are on both sides of the projections of the second connection part 26 and the fourth connection part 28, and the distances between the projections of the first connection part 25 and the third connection part 27 and the projections of the second connection part 26 and the fourth connection part 28 are both greater than the preset distance;

[0045] As Figure 7 shown, the projections of the first connection part 25 and the second connection part 26 are on the same side of the projections of the third connection part 27 and the fourth connection part 28, and the distances between the projections of the first connection part 25 and the second connection part 26 and the projections of the third connection part 27 and the fourth connection part 28 are both greater than the preset distance;

[0046] As Figure 8 shown, the projections of the third connection part 27 and the fourth connection part 28 are on both sides of the projections of the first connection part 25 and the second connection part 26, and the distances between the projections of the third connection part 27 and the fourth connection part 28 and the projections of the first connection part 25 and the second connection part 26 are both greater than the preset distance;

[0047] As Figure 9 shown, the projections of the first connection part 25 and the second connection part 26 are on both sides of the projections of the third connection part 27 and the fourth connection part 28, and the distances between the projections of the first connection part 25 and the second connection part 26 and the projections of the third connection part 27 and the fourth connection part 28 are both greater than the preset distance.

[0048] In the above five cases, it can be ensured that during the transportation of the IBC drum along the conveying line, when passing through the connection part, the pipe column 10 at the bottom of the IBC drum can be supported by the first conveying chain 21 and the first auxiliary conveying chain 23, or by the second conveying chain 22 and the second auxiliary conveying chain 24. Whether it is the former or the latter, the distance between the two conveying chains is greater than half of the distance between the first conveying chain 21 and the second conveying chain 22, so as to provide stable support for the IBC drum and prevent the pipe column 10 at the bottom of the IBC drum from falling into the V-shaped depression of the connection part.

[0049] The preset distance is the radius of the sprocket at the connection part, so that when the pipe column 10 of the IBC drum is located in the middle of one of the connection parts, the other connection parts can provide support for the pipe column 10 at its position due to the misalignment exceeding the radius of the sprocket.

[0050] When the radii of the sprockets at each connection part are different, the radius of the smallest sprocket is used as the preset distance.

[0051] Optionally, the first conveying chain 21, the second conveying chain 22, the first auxiliary conveying chain 23, and the second auxiliary conveying chain 24 are driven by the same motor 29, so as to save energy consumption, reduce manufacturing costs, and have better transmission consistency.

[0052] Optionally, the motor drives the drive shaft to rotate through a driving sprocket group, and the driving sprockets of the first conveying chain 21, the second conveying chain 22, the first auxiliary conveying chain 23, and the second auxiliary conveying chain 24 are respectively installed on the drive shaft.

[0053] Optionally, the first conveying chain 21, the second conveying chain 22, the first auxiliary conveying chain 23, and the second auxiliary conveying chain 24 have the same length.

[0054] Optionally, the projections of the first connection part 25 and the second connection part 26 in the conveying direction do not overlap, so as to prevent the pipe column 10 at the bottom of the IBC drum from reaching the positions of the first connection part 25 and the second connection part 26 at the same time during the transportation of the IBC drum along the conveying line, thus ensuring smooth transportation.

[0055] Optionally, in the conveying direction, the distance between the first connection part 25 and the second connection part 26 is greater than the preset distance, which can further ensure the smooth transportation of the IBC drum on the conveying line.

[0056] Optionally, a power-free drive transition roller set or a transition pulley set is provided on the inner or outer side of the first connection part 25 and the second connection part 26. The height of the transition roller set and the transition pulley set is the same as that of the first conveyor chain 21, and it can assist the chain conveyor unit 20 in conveying the IBC barrel.

[0057] The multi-chain conveyor line provided by the present invention adds a first auxiliary conveyor chain 23 and a second auxiliary conveyor chain 24 to the multi-chain conveyor line, and makes the conveyor chains meet preset conditions, so that when the multi-chain conveyor line conveys goods with uneven bottoms such as IBC barrels, it can overcome the jamming or collision caused by the V-shaped depression at the connection part, thereby ensuring smooth conveyance.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope described in this specification.

[0059] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
