Before you buy a tote box-any tote box-it will pay you to spend a few
minutes in a simple analysis of your needs. We have devoted these pages
to helping you to make this analysis. We hope that it will enable you to
get the most for your material handling dollar.
What is a tote box?
Functionally, a tote box is a container which facilitates handling, storage,
and processing of products and supplies. A single box may perform all three
functions during a span of a few minutes; for now, however, let's consider
them separately.
HANDLING
Products, including parts and sub-assemblies, must often be moved prior
to shipping as finished goods. This movement may be between storage areas
and assembly areas, or from a production area to a shipping area. It may
be a few feet, or interplant over many miles. It may be by hand, cart, conveyor,
lift truck, or semi. In each case, the hand load is usually the basic module.
An efficient hand load consists of as much weight or bulk as one person
can carry with safety. Few parts or products constitute an efficient hand
load, in and of themselves. A tote box of a size and configuration to combine
the largest practical number of parts into one hand load unit is the most
practical method of handling parts and assemblies.
STORAGE
There are three important considerations when ordering containers for parts
and product storage purposes.
1. Protection of contents: The container acting as a barrier against
damage should include a cover to prevent contamination from dirt and moisture.
It should be indestructible enough to withstand contact with other containers
or objects stored next to or on top of one another.
2. Efficient use of space: The size and shape of the container
should be considered as it best fits the storage area, whether it be racks
or shelving, whether you plan to store the containers separately or stack
them.
3. Ease of identification: To facilitate storage inventory control,
the container you use should be labeled and, if possible, have see-through
covers so quantity and contents type can easily be determined. |
PROCESSING
Ideally, component parts should be transferred into tote boxes in the receiving
department, at the very beginning of the process cycle. As the parts are
incorporated into sub-assemblies, they again can be housed in tote boxes
and moved through the system until the finished product is ready to be packaged
for shipping. In some cases the tote box can be used for shipping purposes.
Other considerations include availability of space for containers at
work stations and handling of contents for safe and efficient assembly and
processing. Size of container will vary according to whether the operator
is standing or sitting, by the variety of components to be assembled, and
by the volume of parts required to maintain desired production rate. A wide
variety of parts often calls for a variety of small containers at an assembly
station. Alternatively, compartmented or kitted boxes, which will accommodate
a mixed supply of parts for final assembly, can be used. In choosing the
best container avoid boxes with sharp corners, or those made of materials
which might chip or splinter. to eliminate the possibility of damage or
contamination to delicate parts.
ECONOMIC CONSIDERATIONS
The "cost per use" is the key consideration in the selection of
a container or tote box. Paying 25 cents for a paperboard box, using it
once, and throwing it away, may be false economy compared to purchasing
a box for $2.80 which may be used 100 times or more.
The cost of a box includes, in addition to base price, cost of acquisition,
projected costs of maintenance during its useful life (e.g. cleaning and
painting), and cost of disposal. Environmental problems associated with
disposal are becoming more involved and more costly every day.
The "use" of a container depends on its function. In storage,
"use" can be determined by time and environment; in handling or
processing, "use" can be measured by the number of production
cycles involved. In either case, the obsolescence factor must be considered;
an expensive, custom box closely tailored to current requirements may have
a shorter life than a more versatile, and perhaps less expensive box.
Other "hidden cost" factors to consider include possible damage
to contents as a result of container-caused hostile environment (e.g. rust,
paint chips, splinters, cardboard chaff, moisture, dust, etc).
