Definitions
- This invention relates to the recompression of large bales of fibrous material, and more particularly to an improved method of recompressing said bales.
- Hay and other forages for feeding and bedding animals must often be transported over great distances from the place of production to the location of the animals. It is not uncommon to ship large quantities of hay and straw to dairies, feed lots, or race tracks located near or in metropolitan areas, and to other locations to where hay, grass and straw cannot be grown, or where there is limited availability of land on which to grow hay, grass and straw.
- hay will be used in a generic sense to describe cut foliage, particularly normal hay, such as that made from alfalfa, grasses used as feed, and straw. Also, while this invention is ideally used to recompress bales of “hay,” said generic term is intended to include any material that may be recompressed using the invented method, including, but not limited to cotton, cardboard, etc.
- Hay is typically harvested in the United States by use of hay balers, either of the type that produce square bales or, round bales.
- the use of square bales is by and far the most common method of harvesting hay.
- These bales are constructed of predetermined densities by the bale machines within a certain normal range of densities. In determining the density of the hay in the standard field bale, consideration is given to optimizing storage life, optimizing food value of the product, minimizing damage through high or low moisture contents and the actual weight of the bale that has to be handled by the farmer or stockman.
- the first drawback revolves around the amount of pressure required to recompress the bale.
- the bale is held together through use of a plurality of ties or straps. These straps/ties are typically baling straps, twine or wire.
- the bale In order to strap/tie the recompressed bale, the bale must be overcompressed six to ten inches to allow for proper operation of the strapping/tying apparatus. With regard to a 22′′ bale, the resulting overcompression is 6 to 10 inches (anywhere from 27% to 46% of the length of the bale). Thus, the prior art press actually overcompresses the bale down to roughly 13 inches long, ties the strapping, and then releases the compression, thereby allowing the bale to expand back to the desired 22 inch length. This degree of overcompression requires high pressure on the face of the hydraulic plunger, often ranging from 800 to 1300 pounds per square inch.
- the second side effect is if the hay is a little dry and fine stemmed, the high force will disintegrate the stem, thereby turning the hay into powder. Obviously, buyers are not pleased when they cut the strings on a hay bale and a portion of the bale disintegrates into dust.
- the second “drawback” with the 22-inch bale process is in stacking them inside a standard cargo container.
- a standard cargo container is 92 inches wide, and thus four 22-inch bales can fit lengthwise across a container, with 4 inches of wasted space (air).
- bales of fibrous material which does so using low pressure, thereby reducing matting and dusting, using less power, needing less iron/steel framework to contain the lowered pressure needed, and causing less wear and tear on the compression equipment.
- a method of recompressing bales of fibrous material which eliminates wasted space in cargo containers when said bales are stacked therein. The present invention solves these needs.
- the present invention is a method of producing recompressed bales of fibrous material from previously compressed fibrous material.
- One embodiment of this method comprises the steps of first selecting a quantity of previously compressed fibrous material from 55 to 65 inches long. Then, this material is introduced into a recompression chamber and is recompressed down to 18 to 22 inches long. This recompressed material is tied at 18 to 22 inches long. This recompressed material is transferred, under compression, to a decompression chamber where the material is held for a sufficient period of time for trapped air to escape from the recompressed material and for the material to lose resiliency. This recompressed material is then ejected from the decompression chamber, whereupon the material expands out to a bale of approximately 28 inches in length.

Abstract
A method of recompressing bales of fibrous material which uses longer bales and a lesser pressure force at the plunger head to achieve higher quality recompressed bales having nearly the same density of those made through the standard process.
Description
- 1. Technical Field.
- This invention relates to the recompression of large bales of fibrous material, and more particularly to an improved method of recompressing said bales.
- 2. Background.
- Hay and other forages for feeding and bedding animals must often be transported over great distances from the place of production to the location of the animals. It is not uncommon to ship large quantities of hay and straw to dairies, feed lots, or race tracks located near or in metropolitan areas, and to other locations to where hay, grass and straw cannot be grown, or where there is limited availability of land on which to grow hay, grass and straw.
- For purposes of this disclosure, the term “hay” will be used in a generic sense to describe cut foliage, particularly normal hay, such as that made from alfalfa, grasses used as feed, and straw. Also, while this invention is ideally used to recompress bales of “hay,” said generic term is intended to include any material that may be recompressed using the invented method, including, but not limited to cotton, cardboard, etc.
- Hay is typically harvested in the United States by use of hay balers, either of the type that produce square bales or, round bales. The use of square bales is by and far the most common method of harvesting hay. These bales are constructed of predetermined densities by the bale machines within a certain normal range of densities. In determining the density of the hay in the standard field bale, consideration is given to optimizing storage life, optimizing food value of the product, minimizing damage through high or low moisture contents and the actual weight of the bale that has to be handled by the farmer or stockman.
- However, it is uneconomical and impractical to ship these same standard field bales overseas. The freight costs because of the low density and high volumes is often prohibitive. Therefore, a number of methods have been developed to increase the density of the hay bales so as to minimize freight costs. One of these methods involves taking a field bale, or portion thereof, and recompressing it (typically after cutting the field bale into smaller portions) to approximately half its original volume. Then, these recompressed bales can be stacked into standard dry cargo freight containers which can then be transported to a seaport and loaded aboard a containerized cargo ship for shipment overseas.
- Through such a process, a field bale of alfalfa or grass hay with approximate dimensions of 32″×35″×96″ (32″×48″×96″) bales are also common) and a density of 12-14 pounds per cubic foot is cut and recompressed into 12″×16″×22″ (or 16″×18″×22″) bales which have a density of ˜28 pounds per cubic foot. U.S. Pat. No. 5,893,309 (Ast) protects this process. This 22″ length is the industry standard export bale length. These 12″×16″×22″ bales weigh on average 65 pounds, and the 16″×18″×22″ bales weigh on average 100 pounds.
- There are two drawbacks with this process. The first drawback revolves around the amount of pressure required to recompress the bale. As with any typical bale of fibrous material, the bale is held together through use of a plurality of ties or straps. These straps/ties are typically baling straps, twine or wire.
- In order to strap/tie the recompressed bale, the bale must be overcompressed six to ten inches to allow for proper operation of the strapping/tying apparatus. With regard to a 22″ bale, the resulting overcompression is 6 to 10 inches (anywhere from 27% to 46% of the length of the bale). Thus, the prior art press actually overcompresses the bale down to roughly 13 inches long, ties the strapping, and then releases the compression, thereby allowing the bale to expand back to the desired 22 inch length. This degree of overcompression requires high pressure on the face of the hydraulic plunger, often ranging from 800 to 1300 pounds per square inch.
- Using high pressure to recompress the bale has two undesired side effects. The first is that if the fibrous material has a percentage of moisture which is more than 1-2% above ideal, the hay will tend to mat into essentially a 22″ long hay pellet or brick. Obviously, buyers are not pleased when they cut the strings on a hay bale and find a matted bale which does not flake apart into easy to handle and easy to eat portions.
- The second side effect is if the hay is a little dry and fine stemmed, the high force will disintegrate the stem, thereby turning the hay into powder. Obviously, buyers are not pleased when they cut the strings on a hay bale and a portion of the bale disintegrates into dust.
- The second “drawback” with the 22-inch bale process is in stacking them inside a standard cargo container. A standard cargo container is 92 inches wide, and thus four 22-inch bales can fit lengthwise across a container, with 4 inches of wasted space (air).
- What is needed is a method of recompressing bales of fibrous material which does so using low pressure, thereby reducing matting and dusting, using less power, needing less iron/steel framework to contain the lowered pressure needed, and causing less wear and tear on the compression equipment. What is also needed is a method of recompressing bales of fibrous material which eliminates wasted space in cargo containers when said bales are stacked therein. The present invention solves these needs.
- The present invention is a method of producing recompressed bales of fibrous material from previously compressed fibrous material. One embodiment of this method comprises the steps of first selecting a quantity of previously compressed fibrous material from 55 to 65 inches long. Then, this material is introduced into a recompression chamber and is recompressed down to 18 to 22 inches long. This recompressed material is tied at 18 to 22 inches long. This recompressed material is transferred, under compression, to a decompression chamber where the material is held for a sufficient period of time for trapped air to escape from the recompressed material and for the material to lose resiliency. This recompressed material is then ejected from the decompression chamber, whereupon the material expands out to a bale of approximately 28 inches in length.
- Still other objects and advantages of the present invention will become readily apparent to those skilled in this art from the following detailed description wherein I have shown and described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated by carrying out my invention. As will be realized, the invention is capable of modification in various obvious respects all without departing from the invention. Accordingly, the drawings and description of the preferred embodiment are to be regarded as illustrative in nature, and not as restrictive.

- FIG. 6 is a schematic representation of the side view of the recompressing apparatus of FIG. 1 showing a step following the view of FIG. 5.
- FIG. 7 is a perspective view of a needle and knotter assembly.
- First referring to FIGS. 1 and 2 the fibrous
material bale recompressor 10 is shown to advantage. Thebale recompression chamber 13 is defined byend plate 34,top plate 36 and side plates (not shown). In the preferred embodiment therecompression chamber 13 unenclosed and is open at the bottom todecompression chamber 14 which is defined byend plate 34, side plates (not shown) and decompressionfront plate 35. - It is common with fibrous material bale recompression to create a continual column of hay formed by aligning a plurality of bales, or portions of bales end to end. A length of material or “charge” from this continual column of hay is selected and recompressed. A charge is typically longer than a standard field bale, however the term “charge” as used herein is also intended to include appropriately lengthed field bales. It is preferred for this invention that an
uncompressed charge 37 of fibrous material be 55 to 65 inches long, depending on the weight and density of the continual column of hay. - Referring to FIG. 1, a
charge 37 is placed onto thebottom slide plate 26 in a position where thecharge 37 is correctly positioned for insertion into therecompression chamber 13. FIG. 1 shows a side plate entrance for the charge, however other entrances, such as a bottom entrance, are also envisioned and would work as well. - Once the
charge 37 has been properly positioned onbottom slide plate 26, in position to be recompacted, a recompression plate(s) 15, attached to arecompression ram 16, pushes thecharge 37 into therecompression chamber 13, as shown in FIG. 2. - In one embodiment, in the process of being pushed into
recompression chamber 13,charge 37 preferably intercepts a wrapping means comprising four or more strings ofbale twine 32, which originates from four or more twine spools 33, saidtwine 32 being threaded throughneedles 20 and attached toknotter 19.Charge 37 pushes thetwine 32 ahead of it. When the front ofcharge 37 reaches endwall 34 it has wrappedbale twine 32 around the bottom front and top of thecharge 37. When therecompressed bale 37, as shown in FIG. 2, is in a fully compressed state,needle activation device 23 activates to swingneedles 20, attached toneedle yoke 22, by means ofneedle arms 21, up throughslots 30 inbottom slide plate 26. - As is shown in FIG. 8, slots31 are provided in
recompression plates 15 so as to permit travel ofneedles 20 fromslots 30 in the bottom slide plate up to needle opening 44 intop plate 36.Needles 20 in the process of sliding upward throughslots 30 andbottom slide plate 26, carry with thembale twine 32. When needles 20 are fully extended, as is shown in FIG. 2, they engageconventional knotters 19 which operate to: tie knots in the twine which has been wrapped around the recompressed bale; to cut the twine; and to retain the bitter end of thecut twine 32 which is threaded throughneedles 20, as needles 20 are retracted byneedle activation device 23. Also envisioned is the use of a standard bale strapping means, or any means of tying the bale. - In another embodiment, the means of tying the recompressed bale is a standard plastic strapping system which applies plastic straps to the recompressed bales. Other means of tying are also envisioned, including, but not limited to, baling wires.
- The end preferred length of a
recompressed charge 37 is approximately 28 inches long, thus, thecharge 37 is recompressed from 55 to 65 inches down to ˜28 inches in length. To arrive at this 28 inch length, thecharge 37 must additionally be overcompressed 6 to 10 inches (down to roughly 19 inches long) in order for the wrapping means to operate to tie thecharge 37. After the wrapping means ties the charge, thecharge 37 is allowed to expand back out to the ˜28 inch length. Thus, this overcompression is between 21% and 36% of the length of the end product. This degree of overcompression, however, only needs roughly 550 pounds per square inch of pressure at the plunger head—in comparison to the ˜1200 pounds needed for the prior art method. The preferred resulting recompressed bale or charge has approximate measurements of 16″×12″×28″ (or 16″×18″×28″, depending on the wishes of the operator), with a weight of approximately 80 pounds (or 120 pounds for the 18″ version), and a density of on average 27 pounds per cubic food. However, these measurements will vary depending on the fibrous material recompressed. - The desired density range for the export bale market is 23 to 28 pounds per cubic foot. From experimentation, the inventor has been able to use the invented method to produce bales in the desired density range (23-28 pounds per cubic foot) through using between 400 and 625 pounds per square inch of pressure on the plunger head (recompression plate). Compared to the prior art method, which must use between 800 and 1350 pounds per square inch of pressure on the plunger head to achieve the same density, the inventor is very pleased with the performance of the present invention.
- Because the overcompression in this method is between 21% and 36% (remembering that the overcompression in the prior art method was 27% to 46%), less force is required at the recompression plate(s)15. While the prior art method typically requires a 450 hp engine to exert the required 800-1300 pounds per square inch of force at the plunger head, with the invented method, a 225 hp engine can easily be used because the required pounds of force is reduced to ˜550 pounds per square inch at the plunger head, a savings of at least one-half.
- Referring to FIG. 4, once
bale 37 has been tied, and thetwine 32 cut, with the bitter end retained byknotters 19, and theneedles 20 withdrawn, and prior to withdrawal ofrecompression platen 15,ejection ram 17 is activated so thatejection platen 18 pushes recompressedbale 37 intodecompression chamber 14. As is shown in FIG. 3, the end ofrecompression platen 15 is aligned with the decompressionchamber front plate 35 so thatrecompressed bale 37 will slide intodecompression chamber 14 while remaining in a fully compressed state. - Next referring to FIGS. 3, 4,5, and 6, operation of the
recompression apparatus 10 utilizingdecompression chamber 14 is shown to advantage. First referring to FIG. 3, it is shown thatrecompressed charge 37, is pushed intodecompression chamber 14 only far enough to define a defacto bottom plate forrecompression chamber 13. In FIG. 4, asecond charge 38 is being recompressed. In FIG. 5, thesecond recompressed charge 38 is pushed byejection platen 18 intodecompression chamber 14, thereby pushing or displacing thefirst recompressed charge 37 down into the second position ofdecompression chamber 14. - When a
third charge 39, as is shown in FIG. 6, is recompressed and pushed intodecompression chamber 14,first charge 37 is ejected by the displacement action indecompression chamber 14. As can be seen,first charge 37, and each charge thereafter remains in thedecompression chamber 14 for two full cycles of recompression operation byrecompression apparatus 10. The result is that each recompressed charge is held long enough for trapped air to escape and for the fibrous material to loose some of its resiliency prior to the time thebale twine 32 is subjected to the full recoil, expansion stress of a recompressed charge. - While there is shown and described the present preferred embodiment of the invention, it is to be distinctly understood that this invention is not limited thereto but may be variously embodied to practice within the scope of the following claims.
