Bailing and automatic stowing system for electric conductors

Abstract

The bailing and automatic stowing system is designed for the winding of electric conductors, particularly for automotive harnesses, and is characterized by an arrangement consisting of: a conventional cutting table with electronic control arranged in the reels as support of up to seven stacked packings; an octagonal packing of three octagonal cardboard or plastic pieces, specially designed for the electric conductor roll and a metal universal cabinet to accommodate up to four stowages of piled packings for their storage.

Description

BACKGROUND OF THE INVENTION

There are different ways or designs for packing electric conductors, which are semiautomatic, automatic, or in manual mode. These designs are affected by the way the rolls are packed, whether they are in common reinforced cardboard boxes or with a hoop for transportation purposes or in cylindrical cardboard drums which usually weigh over 100 kg.

In order to reduce inventories and distribution costs, the applicant has designed a bailing and automatic stowing system for electric conductors. This system offers cable presentations seven times smaller compared to the traditional packing in 30-inch high cardboard drums.

The packing presentation of a smaller quantity of cable made it possible to have more flexibility in cutting operations, since it allows cutting the same product in several machines and having more than one 6-inch high package in a machine when required.

Moreover the presentation in a package of a smaller quantity which is an object of the present invention made handling easier for the users, because the conventional drum weight is about 120 kg., while the 6-inch high package (about 15 cm) presents a maximum weight of 20 kg.

The same package can be used several times, which is an advantage for the user and the supplier.

The internal transport of the packaged product is easier because it includes in the packing a rack that allows the use of two superposed stowages on two levels. For shipment, the product is placed in two superposed wooden stowages that correspond to the capacity of a trailer.

DESCRIPTION OF THE INVENTION

Hereinafter the invention will be described according to the drawing of the FIGS. 1 to 8 , where:

FIG. 1 shows the bailing and stowing system from an isometric view on an automatic cutting table of electric conductors rolls for automotive harnesses.

FIG. 1.1 shows an isomeric view of a sectional cut of FIG. 1 , with one individual packing.

FIG. 2 shows a top view of an individual, octagonal cardboard packing for electric conductor rolls.

FIG. 2 a illustrates the assembly sections A, B and C of packing.

FIG. 3 shows a lateral view of FIG. 2 .

FIG. 4 shows a lateral side of a stowage with seven modules of stacked packings.

FIG. 5 shows a top view of an electric conductor roll.

FIG. 6 shows a lateral view of FIG. 2 .

FIG. 7 shows a lateral view of a module of seven piled packings inside a rack of four modules, for storage.

FIG. 8 shows an isometric view of the structure of a rack, with a module of seven packings.

The bailing and stowing system shown in FIG. 1 is integrated by a conventional cutting table 10 , that is electrically and automatically set and controlled at the desired height through its supports 14 , to handle the stowage of module 11 , during the rolling of electric conductor rolls for automotive harnesses the seven packings 12 typically made of cardboard and plastic. Each of the packing supports 20 to 25 kg.

A portable rack 13 FIG. 8 with four modules specially designed to be used as container for the internal transportation or storage of the stowage.

The cardboard packing 12 FIG. 2 , and 1 . 1 is designed in three detachable sections A, B, C. The A section is structured as an octagonal container made of a one piece cardboard having two bends. A first bend on every side of the octagonal surface 15 , in its bottom periphery extending upwards to approximately 15 cm. to form a peripheral wall 31 and a second bend 16 at 15 cm. from the first bend extending downwards to approximately 15 cm. to form a reinforcement 18 of the peripheral wall. The second bend 16 after the bend 15 cm. from the first bend also forms the top of the peripheral wall 15 . Alternately disposed on four of its 8 sides are projections 17 reinforced with an additional wall 18 to allow the packing 12 to self-stack with each other to a maximum of 7 packings to form a stowage 11 . Moreover, the packing 12 has a rabbet 19 , in the opposite furthest end of the projection 17 , formed by a folding of two walls, that allows coupling of the adjacent projection 17 with the piled packing. The packing presents in two of its opposites walls, longitudinal hollows that work as handles 20 of the packing.

The B section of the packing 12 is a reinforcement sheath peripherally disposed at a bottom of a space between the A section and the C section; the internal and external peripheries of this sheath are octagonal.

The C section of the packing is an octagonal bridle 28 , FIG. 1.1 situated concentrically relative to the A section. This bridle has the same height as that of the A section. In its lower ends, it also has flanges working as fastening elements that are pressed between the A section and the B section, to define a passage where the electric winding 29 is accommodated.

The cardboard packing 12 , when manufactured with plastic material, may or may not have projections 17 for its self stacking or just have manual handles 21 . Up to seven stowages 22 can be self-stacked.

Operation

The packings were designed to be self-stacked, this permits them to be automatically stowed and filled one by one with the reels or coils of automotive cable being supported on the cutting table. The seven packings are filled one by one until they form a stowage, continuity tests are automatically made on the reels.

Once the seven packings are filled they are removed from the reel being assisted by the cutting table and by a roller conveyor.

When the packings are ready to be stored, they are set in the four modules 11 of the rack 13 . The four posts 23 are set and another rack is stowed to send them to a double level.

The Objects of the System of the Invention are

Reduction of Process Inventory

The 6-inch high packing capacities are seven times smaller than the capacities of the packing in 30-inch high drums.

Handling Facilities

Conventional 30-inch drums weigh up to 120 kg which makes their handling difficult, while the 6 inch packings herein weigh 20 kg. maximum and are equipped with handles to help the operators in handling them without any difficulty.

Reuse

The 6-inch packings can be reused several times; this means that the distribution costs will be reduced.

Reduction of Obsolete Inventories

When a product is not of high consumption, there is an opportunity to ask for it in smaller amounts so when the automotive model is changed, the risk of having it as obsolete inventory is reduced.

Reduction of Polluting Material

The 6-inch high packing is made of 100% cardboard or 100% polyethylene, and thus has a smaller amount of substances that pollute the environment. The traditional drum has metal rings hooked to the lower and upper parts so that it is difficult to take them away from the cardboard.

Rack 13 Description FIG. 8

A Universal rack is provided to store the cable packings for several uses.

The rack can accommodate the following:

6-inch high octagonal cardboard packing; distance between opposite faces=60 cm.

Round cardboard packing height=6 inches; diameter: 60 cm.

Cardboard drums=60 cm diameter and various heights: 15 inches, 21 inches, 30 inches and 42 inches.

The rack is a symmetric structure with a housing consisting of an articulated base 24 of tubular profiles 25 arranged in four rectangular sections to accommodate four stowages with seven octagonal packings 11 , respectively. The rack 13 has a series of four rigid supports 23 vertically disposed in each corners of the base 24 , the support having one end connecting to the base and an opposite end having a female support 27 , the female support adaptable to a male support 26 on one end of each of the four feet of the base extending downwards, the four feet located in the lower part of the base for stacking the racks.

The rack has four packing accesses and its design permits to pile up to 3 racks, one on top of the other, being of adequate dimensions so they can be stored in the containers of trailers two by two, one on top of the other.

Having described the invention it is considered a novelty so the following is claimed:
