Incline Conveyors

Incline Belt Conveyors

1.Incline belt conveyors are also made up from pre-engineered standard sections, but designed for permanent installation only.    These standard sections are combined to make any length unit required.

2. Incline conveyors are normally equipped with NOSEOVER at the upper end.  This enables the conveyed product to level off to a   horizontal position before being discharged.  This is highly desirable for cartons carrying breakables.  The noseover eliminates a dropping action by the front of the carton when it reaches the top.

3. Incline conveyors can be used as independent units to move material from one level to another.  When used with gravity         conveyor, it provides continuous flow of material from one floor to another.

4. Because conveyor is used inclined, it is equipped with rough-top-belt.

5. Maximum recommended incline for is 25 degrees.

6. Material wider than belt can be moved on the conveyor adequately, if it has a flat solid bottom.  The general rule is,         carton should not exceed the overall width of conveyor.

7. Conveyed items on incline can be moved in two directions – both forward and back. Reversing applications require center        drive.

8. Incline conveyors are available in steel ONLY. However, the portable ALUMINUM type may be used if lengths suffice and if       NOSEOVER is not necessary.

9. Permanent supports are normally used for top and bottom of the conveyors when used as a floor-to-floor unit.

MAXIMUM INCLINES AND DECLINES: The maximum angle of incline or decline of a belt conveyor is function of:

1. Type of Belt being used.
2. The condition of the load. Some manufacturers claim that angles of 35 degrees to 45 degrees are possible.  This is possible if all conditions are perfect and this seldom is the case.

FOR EXAMPLE: A wooden box with a flat rough bottom might negotiate a 25 degree angle; a smooth oily tote pan will probably slide at 15 degrees on that same belt.  The weight of the load has little effect on the problem.  The condition of the bottom and the center of gravity are the most important.  For the uniform packed cartons, the center of gravity is close to the geometric center of the carton and can be located at the intersections of diagonal drawn between opposite corners.  THIS IS NOT TRUE FOR NON-UNIFORMLY LOADED CARTONS SUCH AS TV SETS, COMPUTERS, ETC…
The center of gravity for this type of package can be determined by balancing the load on each of its four bottom edges to note the angle of stability in each direction.

We know that under “static conditions” a load is most stable.  However, belt conveyors do not provide a static condition.  They must start and stop fast and a load must be able to absorb forces such as momentum and acceleration without rocking beyond its stability point and tumbling.

A short load is more vulnerable to toppling than a long load.

Acceleration and deceleration of higher speed belts add to the problem more severely than do slower belts.  Also, the use of magnetic brakes for stopping the conveyor will accentuate the problem associated with the tumbling due to deceleration.
The bottoms of most boxes are normally not flat, but slightly bulged.  This creates some swaying even on level belts.
The spacing of the load supporting roller in a live roller conveyors and also belt conveyors, affect the amount of “bobbling” or “rocking” in transit.  The closer the rollers are the smoother the travel.  Slider bed conveyors provide the smoothest action of all.

How Metro Wire has Helped Others

SOLECTRON

Solectron is a contract circuit board manufacturer located in Milpitas, California.  The company depends on efficiency and cost effectiveness to successfully manufacture quality products. When Solectron was looking for a new cart to handle storage  and transportation needs for circuit boards, they turned to Metro for a custom solution. Although lowering costs was an issue, they also wanted an innovative solution.

Solectron requested a cart to safely hold conductive 18” x 26” trays (an industry standard) for larger and unconventional shaped circuit boards. It was essential that the spacing between slides measure 1.75” to accommodate the taller components on the board. Also, since Solectron builds over 250 different circuit boards, they require a storage system that is universal to all assemblies. Another important feature of the cart was height. Workers are seated when using the cart and trays, and extending past a certain height could create potential problems with dropping products and jeopardize quality.

Solectron was familiar with Metro products and looked to Commercial Products Representative Rick Soulsby and Mark Daniels of Commercial Products Dealer Marshall Industries to recommend a solution. They customized the standard RE1 Metro cart and presented it to Solectron. Says Operations Manager Ken Stuart, “We were completely satisfied with the product and the outstanding service. Rick and Mark went above and beyond our requirements. This easy to maneuver, light cart provides us with a secure platform to hold our circuit boards.”

Metro Wire has been the world ’s leading manufacturer of storage and transport solutions in Commercial Products, Foodservice, Healthcare and Consumer Products.  Metro has been supplying its customers with new and imaginative solutions that put “space to work” in a world that thrives on change.

How are Powered Conveyors Different From Gravity or Roller Conveyors?

What material handling problems can they solve?

A conveyor, when powered with either a belt or chain can dependably preform many tasks of automatic transportation, accumulation, storage and package manipulation.

Powered Roller Conveyor

POWERED conveyor will transport goods across level spans up or down grades, between floors and around turns at controlled speeds.  Distances may be only a few feet or may extend across an antire factory or warehouse.

LIVE ROLLER conveyors ar powered by a belt or line shaft running under the rollers or a chian running through the side frame.  This type of conveyor is used when there is an imbalance between work stations or machine operations, or when side loading and unloading is necessary.  The load may be blocked and realeased without damage while the conveyor continues to operate.  This basic principle can be used as a pacesetter in assembly or sorting operations and as a timing for integrated systems.

POWERED conveyors can eliminate storage handling costs when they are located between operations.  The distances can be almost any length and may or may not be a straight line between use points.

With the use of Intersections, diverters, traffic cops, turning posts and guides, packages may be brought together, sorted and reoriented without manual aid and at full belt speed.

All of these features are available and are specifically designed to reduce material handling costs.

APPLICATION: PACKAGE HANDLING CONVEYORS

First, it should be understood that conveyor application is not an exact science.  Almost always, there are several ways of engineering a system and many factors such as cost, personal opinion and experience will often influence the design.  A sequence of operations is a good way to start.

WHAT FOLLOWS IS GENERAL CRITERIA, BY CONVEYOR TYPE WHERE ENGINEERING FORMULAS WILL NOT ALWAYS APPLY AND WHERE A DECISION BASED ON PERSONAL EXPERIENCE AND EVALUATION IS REQUIRED.

POTABLE BELT CONVEYORS arepre-engineered power driven units.  They are specially designed to move cartons, cases, boxes, bags, etc.  UP AN INCLINE.  They can be used with or without supports as follows:

• Loading and unloading trucks and railroad cars.
• Stacking
• As a booster in a gravity conveyor line.
• On a stairway (not too long or too steep).
• Horizontally (when short & portable unit needed)
• Floor-to-Floor conveyor, when vertical lift required isn’t too great

1. To keep material on the belt when conveyor is inclined – RUBBER, ROUGH-TOP, belting is used.
2. Maximum recommended incline for portable belt conveyor with RUBBER, ROUGH-TOP belt and without cleats is 30 degrees.  With cleats, unti can be inclined up to 45 degrees.   However, keep in mind CENTER OF GRAVITY of material being moved (based on height and length) i.e. if carton is higher than it is long, it will topple back.
3. Material to be moved can be WIDER THANBELT, when it is a solid bottom, i.e. if caton is 18 inches wide, it can easily be moved on a 12 inch wide belt (minimum belt width =2/3 product width)
4. Belt on PORTABLE units moves in two directions – forward and reverse
5. Portlable belt conveyors are available in STEEL and ALUMINUM models
6. Aluminum belt conveyors can be moved about easily, even without supports.
7. Under carriage supports are available for standard units.  Thee supports are ADJUTABLE and PORTABLE and should be sold when quick adjustment and easier portablity are desired.

Choosing the Right Hamilton Caster

It’s important to select the casters and wheels that will do your job best. In this way you can be sure of getting top performance without spending a whole bunch of money and equally important, selecting the right wheel or caster will save money in the long run by heading off downtime, excessive maintenance costs, and premature replacement. Wheels and casters are offered in various shapes and sizes, this is so that you will be able to choose the correct caster for your needs. For original equipment manufacturers, it can mean the difference between enhancing the mobility and life of a product… or inviting unhappy customers with every sale.

Here are some things to consider.

Capacity: What will the maximum load be? Do not forget to add the weight of the vehicle as well. Does the possibility of overload, shock loading, or poor floors call for a safety factor? Because of varying conditions and differing corporate philosophies, capacity ratings may differ from one manufacturer to the other and should never be used in place of specifications for making comparisons.

Floor Conditions: What are the floors going to be like? Are they smooth or rugged?  Must elevator sills, railroad tracks or dock plates be traversed? Are there cracks or harmful substances on the floor? And don’t forget about floor protection. In general, resilient wheels are required for rough floors or power-towed equipment.

Operating Environment: Is noise an issue? Are water, oil, grease, chemicals or temperature extremes present? Special lubricants can be provided, as well as special bearings or sealed bearings. Frequent movement demands longer-wearing components than occasional movement.

Rollability: If loads are to be pushed manually, select the largest practical wheel diameter, anti-friction bearings, and the kind of wheel that will start and roll easiest over the surface in question. On smooth floors, the harder the tread the easier it will roll. Conversely, soft tread wheels-desirable for rough floors, outdoor use, or for cushioning loads-can be difficult to push manually under heavy loads.

Pallet Rack Hazards

Misalignment of Racks: To prevent misalignment of racks adhere  to manufacturer’s installation drawings and specifications. Connections should be checked done on the vertical plane to make sure that rack is properly aligned from front to back.

Improper Beam Installation: The solution to this problem is periodic inspection of all beam connections. It is also important to verify the initial installation with the manufacturer’s instructions.

Inadequate Clearances: Use the clearance specifications provided by the manufacturer. Make sure there is enough room to clear the front and back beams so that it can be withdrawn safely. Also make sure the truck radii for entrance and exit is large enough.

Improper Aisle Width: Refer back to the original drawings of the manufactuerer’s designs and the original layouts of the racks at installation and verify the consistency of the pallet load to the beam spacing to the aisle width; also, determine what size the aisle was designed  to accomodate the particular material handling equipment and inadequate load-to-load dimensions for a new truck.

Dislodgement of Accessories: Have a professional maintenance program that requires checking of fasteners and verifying that all loose accessories, cradles, and materials are indeed on the rack structures in the way prescribed by the manufacturer.

Spillage of Goods or Overloading: Care should be sure that loads are intact and bound by plastic wrap or placed in bins. Inspect rack items to make sure that there are no packages hanging out. Spilled material should be picked up at once.

Wheel Chocks for Industrial Use

Checkers manufacturers a diverse line of rubber and urethane wheel chocks for industrial and aviation applications.

Wheel chocks are definitely one of those precautionary measures that you think you never need and then you only realize you need them when they’re not there and your car rolls away.

Wheel chocks are a relatively inexpensive investment for your safety and the safety of others. Anyone who’s shopped for chocks knows there are a few of varieties of options available on the market. Here at Material Flow we have a large variety of Wheel Chocks to chose from So, how do you decide which Chock is best for you.

Wheel chocks come in many  different shapes and out of different materials. All, are inclined planes; if used correctly, each should perform the job. Since all chocks provide a hill for a wheel to climb if it wants to roll, it doesn’t matter if it’s one inch or one yard high. That lack of difference pertains only to a perfect wheel, though, and tires are not perfect wheels as they can change their shape. Tires aren’t rigid, so a tire can bend around a small enough chock and continue on its roll downhill. In the case of selecting a wheel chock for tires, the bigger the better.

The type of vehicle you have and tire you plan on chocking also make a difference in the chock you choose. Heavy, off-road tires used on large equipment like excavators and grading equipment require a different chock than your family sedan. Check the package to find out what kind of vehicle the chocks you’re purchasing were designed to accommodate. You can also visit our site at Material Flow and Conveyors or call us at (800)338-1382

Caster Wheel Bearing Options

Precision Tapered Roller Bearings.

These bearings are ideal for heavy duty and power-towed caster applications because their tapered faces will handle any assortment of downward and side force

Double bearings are installed in each wheel, one in each side of the hub, consisting of a cup (hardened and ground outer raceway) and cone (roller assembly). Spanner bushings are not employed since adjustment requires tightening caster legs against the bearing assembly. Tapered bearings extend overall hub length of the wheel itself by approximately 1/4″. (Shown above with optional integral seal.)

Precision Ball Bearings.

These Precision Ball Bearings work best when roll ability is important and side thrust is not a critical factor. (Tapered bearings are best suited where side thrust is critical.) The bearings are pre-lubricated and sealed at the factory so greasing is not required, reducing maintenance costs… Double-sealed precision ball bearings (shown on left) incorporate steel reinforced rubber seals securely fastened to a groove on the ring of both sides of the bearings. They now replace straight roller bearings in the majority of our casters using polyurethane tread and solid urethane wheels and can be provided optionally on many other wheel types.  Shielded stainless steel precision ball bearings are used in our stainless steel and solid urethane wheels to prevent rusting and improve roll ability.  On special order we can supply additional sizes and configurations including flanged, sealed square bores, extended inner raceways, and wide inner raceways with self-locking collars.

Straight Roller Bearings.

These are most popular anti-friction bearing for industrial equipment. Consists of a cage-type roller assembly, and an outer race that may be separate or integral. (Note: plastic retaining washers or other components may be used unless we are advised of a high-heat application.)

Oilless Sleeve Bearings.

A sleeve, usually of sintered iron or oil-impregnated bronze, is press-fit into the wheel bore. Lacks the ease of movement anti-friction bearings provide, but practical for light loads or where re-lubrication is a problem. (A light application of oil or graphite improves rollability and extends bearing life.)

Plastic Bearings.

For environments detrimental to metal bearings, acetyl resin bearings offer chemical and corrosion resistance. Delrin® (registered DuPont trademark) is a standard offering in certain wheels, as either a sleeve or flange type bearing. Note: flange type bearings extend actual hub length of wheel approximately 3/16″.

Non-Precision Ball Bearings.

The standard ball bearings referred to are the unground radial type, intended for light-to-medium duty use.

Plain Bore.

The term applied to running machine-bored wheels directly on an axle; hence, the absence of a bearing. Suitable for light or seldom moved loads, where ease of starting and rolling is not too important or where price is a dominant factor.

Special Bearings.

For most applications, the bearings discussed above work quite effectively. However, there is an occasional requirement for bearings with special features and characteristic.
