Case packers

Case packer. This collects and arranges the bundles in the required patterns, then pulls down a shipping carton from the magazine and loads the pattern into the erected case.

The case-packing function is one area of the packaging line that can benefit greatly from automation, since this function is one of the most labor-intensive areas of a packaging line. Case packers can be high-volume, automatic machines that can handle products more gently than human hands. 

Side load case packers are generally used for packing cartoned products into corrugated cases (although tubes, cans, and other containers may be packed in this manner). However, for oil, side loaded case packers could increase the stress of handling the product, which may result in product damage. 

Glass and plastic bottles are most commonly packed by top load case packers. Top load packers can pack bottles into corrugated cases, plastic cases, cormgated trays, plastic trays, full- or half-depth cases, or nested carriers. The complexity of the cases and product matrix determines the justification for a top loader. 

In using a bottom load case packer for a packaging operation, the containers are accumulated and unitized into the selected case pattern. As the unitized load is indexed onto the lift platform, a case blank is unfolded from the case magazine over the product. The lift platform raises the product into the opened case. The case is indexed out of the loading area and is top and bottom sealed by a hot melt glue system. The bottom load case packer is the best type of case packer for containers that require stacking, pads, or automatic case insertion. 

The figure on the right shows the well with a simple well completion including a production tubing with packer, a series of surface safety valves called a Christmas tree, a subsurface safety valve (SSSV), a circulating sleeve, and a series of perforations through the casing. 

Most squeeze cementing operations take place in cased sections of a well. However, open-hole packers can be used to carry out squeeze cement operations of thief zones during drilling operations. 

Paralleling the corrosion problem is one involving compatibility of any well fluid with nonmetallic materials used in well completion apparatus. All injection wells and many producing wells are equipped with packers to isolate the casing annulus from the high temperature, pressure, and salinity characteristic of the petroleum reservoir environment. Conventional packers, as well as other well tools, utilize elastomeric materials to mechanically seal appropriate locations.

In residue surveys, tissue samples are also collected at random to be submitted to routine testing. If a violative residue is found, the producer is notified and the animals are held in the farm, and tested until they are proven to be residue-free. To provide this proof, producers are allowed to submit a small number of animals for residue evaluation. The marketing status of the producer is reevaluated based on the tissue test results. The carcasses are retained usually for 14-30 days until the test results are available and will be condemned if the results indicate the presence of violative residues. In many cases, producers incur additional expenses for the packer to debone, freeze, and store the retained carcasses.
