Description

Technical Field

[0001] The present invention relates to the field of conveying and sorting, and particularly to a method for calculating the length of a side-edge roller line. Background Art

[0002] With the development of society, people's demand for materials is increasing. To meet people's needs conveniently and quickly, various online shopping platforms and express delivery companies have emerged like mushrooms after rain. In the early days, express delivery companies relied on manual sorting of express deliveries. With the increasing labor costs and the increasingly tense land resources, many express delivery companies have purchased automated express sorting systems. The sorting system mainly includes a roller line, a belt conveyor, a sorting machine, a dynamic scale, a barcode scanning system, software, etc.

[0003] At present, most domestic automated sorting systems will install a section of side-edge roller line in front of the sorting machine to improve the accuracy of sorting and code reading before sorting packages according to certain rules. However, the length of the side-edge roller line is determined according to the experience of designers, so it will cause serious wear of the packages when the side-edge roller line is too long, and reduce the code reading accuracy when it is too short. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for calculating the length of a side-edge roller machine, so that the length of the side-edge roller line is very reasonable, thereby improving the package code reading accuracy and reducing the package breakage rate.

[0005] For this reason, the technical solution of the present invention provides a method for calculating the length of a side-edge roller line. Among them, the roller line includes an electric roller, a driven roller, a frame, a connecting seat, a support leg, and an adjustable floor bolt. The electric roller drives the driven roller to rotate through a multi-wedge belt for transporting goods. The electric roller and the driven roller are installed on the frame. The frame is connected to the support leg through the connecting seat. The adjustable floor bolt is installed under the support leg for adjusting the height. The calculation method includes:

[0006] Obtain the length L2 and width L3 of the goods to be transported;

[0007] Determine the width L1 of the side-edge roller line through the width L3 of the goods to be transported: L1 = L3 + △L, where △L is the width redundancy;

[0008] Determine the angle θ between the roller shaft of the side-edge roller line and the frame;

[0009] Obtain the tangential linear velocity V of the roller of the side-edge roller line and the linear running velocity V1 of the side-edge roller line parallel to the frame;

[0010] Calculate and obtain the length L of the side-edge roller line through the following formula:

[0011]

[0012] V|cosθ = V1 (2)

[0013] (L1 - L3)*cotθ = L V1*t = L (3)

[0014] From (1), (2), and (3), we get

[0015] (L1 - L3)*cotθ = L (4).

[0016] In a further technical solution, the tangential linear velocity V of the rollers on the edge - side roller line is determined by the conveying efficiency and the selection table of the electric rollers, and the linear running speed V1 of the edge - side roller line parallel to the frame is V1 = (L2 + allowance)*efficiency / 60, where the allowance value is 600 mm.

[0017] In a further technical solution, the width redundancy ΔL is 100 mm to 200 mm.

[0018] In a further technical solution, the driven rollers include single multi - wedge - belt - head driven rollers, double multi - wedge - belt - head driven rollers, and short multi - wedge - belt - head driven rollers.

[0019] In a further technical solution, the frame is a steel plate bending part, and grooves for installing electric rollers, short multi - wedge - belt - head driven rollers, double multi - wedge - belt - head driven rollers, and single multi - wedge - belt - head driven rollers are provided on the bending part.

[0020] In a further technical solution, the connecting seat is an L - shaped sheet metal part bent from a steel plate and is provided with arc - shaped waist - shaped holes.

[0021] In a further technical solution, the adjustable feet are composed of screws and foot cups, where the adjustable range of the screws is ±50 mm.

[0022] The calculation method of the length of the roller machine of the present invention makes the processing, installation, and debugging of the edge - side roller machine more convenient and fast, and provides a theoretical basis for determining the length of the edge - side roller machine, thereby making the goods conveying more stable and greatly improving the code - reading accuracy rate.

[0027] The technical solutions of the present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited to these embodiments.

[0028] In the technical solution of the present invention, a method for calculating the length of a side-by-side roller line is provided, wherein the roller line includes an electric roller, a driven roller, a frame, a connecting seat, a leg, and an adjustable floor foot. Among them, the electric roller drives the driven roller to rotate through a multi-wedge belt for conveying goods. The electric roller and the driven roller are installed on the frame. The frame is connected to the leg through the connecting seat. The adjustable floor foot is installed under the leg for adjusting the height. The calculation method includes:

[0029] Obtain the length L2 and width L3 of the goods to be conveyed;

[0030] Determine the width L1 of the side-by-side roller line based on the width L3 of the goods to be conveyed: L1 = L3 + ΔL, where ΔL is the width redundancy;

[0031] Determine the angle θ between the roller shaft of the side-by-side roller line and the frame;

[0032] Obtain the tangential linear velocity V of the roller of the side-by-side roller line and the linear running velocity V1 of the side-by-side roller line parallel to the frame;

[0033] Calculate the length L of the side-by-side roller line through the following formula:

[0034]

[0035] V|ccosθ = V1 (2)

[0036] V1 * t = L (3)

[0037] From (1)(2)(3), we get

[0038] (L1 - L3) * cotθ = L (4).

[0039] In a further technical solution, the tangential linear velocity V of the roller of the side-by-side roller line is determined by the conveying efficiency and the selection table of the electric roller. The linear running velocity V1 of the side-by-side roller line parallel to the frame is specifically obtained through (L2 + 0.6) * efficiency (unit: boxes / hour) / 60 (m / min) (Note: The length of the box plus the margin of 600mm is multiplied by the efficiency and then divided by 60 to obtain the velocity); the velocity that meets the efficiency obtained from this formula should be ≤ V * cosθ = V1.

[0040] In a further technical solution, the width redundancy ΔL is 100 mm to 200 mm.

[0041] In a further technical solution, the driven roller includes a single multi-wedge belt head driven roller, a double multi-wedge belt head driven roller, and a short multi-wedge belt head driven roller.

[0042] In a further technical solution, the frame is a steel plate bending part, and grooves for installing an electric roller, a short multi-wedge belt head driven roller, a double multi-wedge belt head driven roller, and a single multi-wedge belt head driven roller are provided on the bending part.

[0043] In a further technical solution, the connecting seat is an L-shaped sheet metal part bent from a steel plate and is provided with arc-shaped waist-shaped holes.

[0044] In a further technical solution, the adjustable foot is composed of a screw and a foot cup, wherein the adjustable range of the screw is ±50 mm.

[0045] The calculation method of the length of the roller machine of the present invention makes the processing, installation, and debugging of the side-by-side roller machine more convenient and fast, and provides a theoretical basis for determining the length of the side-by-side roller machine, thereby making the goods transportation more stable and greatly improving the barcode reading accuracy. Specific embodiments:

[0047] Please refer to Figure 1 - Figure 2 As shown, in the embodiment of the present invention, a roller machine for the side includes 1 - electric roller, 2 - single multi-wedge belt head driven roller, 3 - double multi-wedge belt head driven roller, 4 - short multi-wedge belt head driven roller, 5 - frame, 6 - connecting seat, 7 - leg, 8 - adjustable floor foot.

[0048] The foot cup of the adjustable foot 8 is fixed on the ground, and the upper adjustable screw and the leg 7 are connected by threads.

[0049] The lower part of the leg 7 is connected to the adjustable foot, and the upper part is connected to the connecting seat 6 by bolts.

[0050] The upper plane of the connecting seat 6 is connected to the frame by bolts.

[0051] The frame is a bending part, and grooves for installing rollers are provided on the bending part for installing the short multi-wedge belt head driven roller 4, the double multi-wedge belt head driven roller 3, the single multi-wedge belt head driven roller 2, and the electric roller 1.

[0052] The electric roller 1 transmits torque and rotational motion to the driven roller through a multi-wedge belt to realize the movement of goods on the surface of the roller line.

[0053] The theoretical calculation formula for the length of the side-by-side roller line is as follows:

[0054]

[0055] V|cosθ = V1 (2)

[0056] V1*t = L (3)

[0057] From (1), (2), and (3), we get

[0058] (L1 - L3)*cotθ = L (4)

[0059] Where, L1: Width of the side roller line (mm);

[0060] L2: Length of the goods (mm);

[0061] L3: Width of the goods (mm);

[0062] L: Required length of the side roller line (mm);

[0063] t: Time required for the goods to move from one side of the side roller line to the other side (s);

[0064] θ: Angle between the axis of the roller of the side roller line and the frame;

[0065] V: Tangential linear velocity of the roller of the side roller line (m / min);

[0066] V1: Linear running velocity of the side roller line parallel to the frame (m / min);

[0067] The methods for obtaining the parameters in the above formulas are as follows:

[0068] θ is determined by the die for frame rolling. Normally, θ is 10°;

[0069] L1 is obtained by L3 + 150mm of the width of the conveyed goods;

[0070] L2 is the length dimension of the goods given by the customer;

[0071] L3 is the width dimension of the goods given by the customer;

[0072] V is the value determined by the conveying efficiency and the selection table of electric rollers.

[0073] When determining the length L of the side roller line, substitute the corresponding parameters into formula (4).

[0074] After being applied in multiple implementation projects, the length of the side roller line calculated by this theoretical calculation formula is very reasonable, which not only reduces the breakage rate of the goods and greatly improves the code reading accuracy, but also makes this structure more compact, stable, and durable.

[0075] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive 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.
