  • 2. Select MWS series chains when antibacterial and/or mold resistant properties are required for conveyor lines for foods and beverages.
  • 3. This includes beer cans, soft drink cans, cans having metal tops and bottoms and fiber sides, etc.
  • 4. It also includes plastic, plastic coated containers and paper containers for dairy products such as milk, cheese and ice cream. Paper plate and bottom such as soap and cereal.
  • 5. This includes glass bottles and glass containers used for liquor, food, pharmaceuticals, cosmetics, etc.
  • 6. This includes machine parts, dies, castings, forgings, metals, bearings, bolts, nuts, etc.

2-2. Select top plate width

Generally, the top plate must be slightly wider than the conveyed products.

When conveyed products are very wide and none of the top plate widths are satisfactory, top plates of the same width may be used in a multi-strand arrangement. Top plates of different widths can be used together, but this is not desirable since the tension on the chains will be uneven.

In addition, plastic modular chains can also be used.

・Top Plate Edge Face Shape for Cut Chains

Cut edges of top plates are chamfered (approximately C0.5 to C0.8). Corners are also chamfered (approximately C2).

Shape of edge face

  • 1. Processed by machining.
  • 2. When manufacturing top plates to a width not noted, edges of top plates will be finished to the above specifications.
  • 3. Special edge shapes are available upon request.
  • 4. For a top plate with a small width, chamfer dimensions may be smaller accordingly
  • 5. Molded chain marks and actual chain width may not be identical because the width of the top plate is machine processed.

  • 4. LFW, LFG, LFB, NLF, WR, HG, MWS series.

Note)

  • 1. It is recommended that sideflexing conveyors be lubricated so that the chain slides smoothly on the wearstrip. In particular, when the sideflex radius spans an angle greater than 90°, the chain and the wearstrip will wear unevenly in a relatively short period of time, and chain float may occur. If lubrication is impossible, consider using a corner disc in the horizontal curved section.

Steps 5. Calculate Chain Tension and Power Required

5-1. Calculating Tension (F) for Straight-Running Movement

Calculating Tension (F) for Straight-Running Movement

Note) SI units and gravimetric units
The formulas are given for both SI units and gravimetric units. When calculating tension F with gravimetric units, the weight (kgf) in gravimetric units is the same value as the mass (kg) in SI units.

Explanation of symbols

  • F = Chain tension 　kN{kgf}
  • m1 = Chain mass 　(kg/m)
  • L = Length of conveying portion 　(m)
  • m2 = Mass of conveyed objects in conveying portion 　(kg/m)
  • L' = Length of accumulating portion 　(m)
  • m3 = Mass of conveyed objects in accumulating portion 　(kg/m)
  • μ1 = Coefficient of dynamic friction between chain and wearstrip 　(See Table 3 )
  • μ2 = Coefficient of dynamic friction between conveyed products and chain in accumulated section 　(See Table 3 )
  • μ3 = Coefficient of rolling friction between conveyed products and plastic rollers 　(See Table 4 )
  • αL = Angle factor when using curved wearstrips 　(See Table 5 )
  • αC = Angle Factor when Using Corner Discs 　(See Table 6 )
  • αS = Length factor 　(See Table 5 )
  • θ = Inclination angle 　( Deg. )
  • r = sideflex radius 　(m)
  • P = Power required 　(kW)
  • V = Chain speed 　(m/min)
  • ηNote) = Transmission efficiency of drive unit

Note) For the mechanical transmission efficiency, check the drive unit used.

SI Unit (kN)

Chain tension

F = 9.80665 × 10-3 { (2.1m1 + m2) L・μ1 + (2.1m1 + m3) L'・μ1 + m3・L'・μ2 }

Power required

P = F・V 60η

Gravity unit (kgf)

Chain tension

F = (2.1m1 + m2) L・μ1 + (2.1m1 + m3) L'・μ1 + m3・L'・μ2

Power required

P = F・V 6120η

Note) When using accumulation chains (such as TTPDH-LBP), calculate by substituting µ3 for µ2 in the equations above.

5-2. Calculating Tension (F) for sideflexing conveyance (with one curved section)

The calculation is basically the same as for straight conveyance. The tension acting on the corner part is corrected using the angle coefficient.

A calculation example is shown for the conveyor route below. Lubrication is recommended for curved conveyance where the chain and wearstrip slide against each other. In particular, when the sideflex radius spans an angle greater than 90°, the chain and the wearstrip will wear unevenly in a relatively short period of time, and chain float may occur. If lubrication is impossible, consider using a corner disc in the horizontal curved section.

[Tension at section C ：FC]

L2 = r × αS 90°

[Tension at section D ：FD]

FD = FC + {(m1 + m2) L1・μ1 + m3・L1・μ2}

Note

  • 1. When using curved accumulation chains (such as type TPUS-LBP), calculate by substituting μ3 for μ2 in the equations above.
  • 2. When using corner discs in the curved section, replace the angle factor αL with the corner disc angle factor αC for calculation.

5-3. Calculating Tension (F) for Sideflexing Conveyance (with Two Curved Sections)

When sliding the chain against curved wearstrip, no more than two 90° curves should be allowed in one conveyor. Otherwise it may cause pulsation of the chain movement.

To include additional curved sections, consider splitting the conveyor into sections or use the corner disc system.

L2 = r × αS 90°

[Tension at section F ：FF]

FF = FE + (m1 + m2) L1μ1 + m3・L1・μ2

Note

  • 1. When using curved accumulation chains (such as type TPUS-LBP), calculate by substituting μ3 for μ2 in the equations above.
  • 2. When using corner discs in the curved section, replace the angle factor αL with the corner disc angle factor αC for calculation.

5-4. Calculating Tension (F) for Sideflexing Movement (Horizontal Drive)

Applicable Chains TPUH-BO (horizontal conveyance), Plastic Crescent Chain (TORP, TOSP), Stainless Steel Top Chain (TO, TU)

The calculation is basically the same as for straight conveyance. The tension acting on the corner part is corrected using the angle coefficient.

A calculation example is shown for the conveyor route below.

Conveyor layout

F = 9.80665 × 10-3  ・FC (kN)

5-6. Calculating Tension (F) for Inclined Movement

The effects of speed, conveyed products, center of gravity, mass, environment, and other parameters will make it difficult to determine precisely the maximum inclination angle.

Although the values given in Table 8 can serve as guidelines, it will be necessary to perform tests.

Steps 6. Decide Chain Type

Select a top chain having a maximum allowable load larger than the maximum tension (F) to be applied to the chain.

To obtain the maximum allowable load, refer to the allowable load graph, and specify the chain speed and operating temperature on the diagram.

See each product page for allowable load graphs.

F ≦ Maximum allowable load of the chain (coupled with speed and temperature )

When the maximum allowable load is insufficient, it can be corrected by using top plates with narrower width and increasing the number of chain strands, or by splitting it into many short conveyors.

Also selecting a chain with a larger maximum allowable load.

To determine an optimum chain type, remember to take environmental conditions into account.
