The present invention relates to a method and apparatus for producing solid or flowable materials, in particular irregularly shaped materials, such as bulk materials, flowable granules, in particular, packaged packages of frozen carcasses. The packaging technology according to the invention is mainly for the overseas transport of goods.

Currently, the transport of irregularly shaped goods such as frozen carcasses on board causes serious problems that the interior of the containers cannot be used efficiently and loading and unloading requires significant manual work. The goods stored in the containers are disorderly in the interior of the containers, so they can only be loaded manually.

Container transport of carcasses usually requires special container vessels, so vessels not specifically designed for container shipping cannot be considered. Additionally, container ships can only be loaded and unloaded at ports that are equipped with special container handling equipment. Harbors that are smaller and non-containerized can therefore not be used for loading meat delivered in containers. As a result, transport costs increase as the meat processing plant is generally away from the container port and the loaded containers must be transported by rail or road to the container port. A further drawback of container transport is that the loading and unloading of carcasses into the container also requires considerable work.

It is known from WO-86/06345 that a frame fixed on a pallet used for the transport of goods is loaded into the container thus formed, and then a hose-like plastic foil is applied as a cover to the load. However, this solution can hardly be considered for the production of unit packets for a wider application due to the high cost and excess weight of the remaining frame structure.

U.S. Pat. No. 4,309,861 describes an expandable frame for expanding a foil tube while coating a container with a tubular extensible cover. This solution is only applicable to bulk goods, ie very limited and only to tubular packaging materials. Essentially, a similar solution is proposed in U.S. Patent No. 183,901, according to which the tubular casing is stretched by air jet to be pulled onto the load, which requires relatively complicated and time consuming and energy consuming cutting, welding and gripping structures.

It is an object of the present invention to overcome the above-mentioned disadvantages, i.e. to provide an improved solution that can pack bulk and bulk or even flowable goods as widely as possible, with relatively little effort, as a unit load, even for sea transport. It is a further object of the present invention to provide an improved method and apparatus for solving, in particular, irregularly shaped products such as frozen carcasses and loading onto pallets, whereby the storage space can be utilized to the maximum, the treatment time can be minimized, and the advantages of palletizing in freight handling can be exploited well.

The object of the present invention has been solved by a method according to the present invention, which is intended for making a packed unit packet for solid or flowable materials, especially sliced meat products. Here, a storage space is formed with a frame structure, filled with the material to be packed and covered with a plastic wrapping film. The essence is that by using an open frame structure, an open storage space of a volume corresponding to a predetermined size unit packet is formed, and before and / or after filling the storage area with or with the material to be packed, the storage area bounded at least partially by the open frame structure is wrapped with a wrapping film formed as a plastic strip, and thereby creating a storage container and finally removing the frame structure from the package thus created.

The process according to the invention can therefore be used for packaging bulky bulk materials, such as granules, granules, liquid slurries, plastic granules, cereals, fertilizers and waste materials.

It is preferable that the wrapping film be prestressed and tightly wrapped around the open frame structure, as this will allow for more compact and more compact packages. The open frame structure can be used to form square or cylindrical or any other storage space.

An apparatus having a frame structure, a fixed base unit and a plastic foil casing may be used to implement the above process. According to the invention, this has been further developed by having an open frame structure releasably connected to the load-bearing base unit. The casing is formed as a storage container formed by wrapping a wrapping foil and the open frame structure is at least shaped like a wrapping foil wrapped around its vertical mantle. The base unit of the load handler is a container end closure, preferably a pallet receiving and optionally remaining within the package. The charged foil container has a tightly sealing unit.

Thus, in accordance with the present invention, the storage space bounded by the open frame structure is wrapped in such a way that the frame structure and, where appropriate, the load-bearing base unit are wrapped at least partially with the wrapping foil, then the frame structure is removed, i.e. removed or, for example, telescopically folded, i.e. recovered and reused for further unit packets. It is further preferred that the frame structure is separated from the package by lifting. Preferably, the portions of the frame structure in contact with the wrapping film are coated with a friction reducing agent.

Preferably, the frame structure delimiting the storage space has vertical elements, especially strut rods, or frame bars, which are at the side of the base unit2

HU 217 568 Β are placed vertically. It is preferred that the four vertical legs of the frame structure are releasably connected to the corners of the load-bearing base unit. An arrangement is also possible in which the load-bearing base unit and the frame structure are formed as a combined structure, which is tilted in a substantially vertical release position from the horizontal loading position.

The invention will be described in more detail with reference to the accompanying drawings, in which some exemplary embodiments of the present invention are illustrated. In the drawing:

As shown in Figure 1 -4. 1 to 3, the packing apparatus according to the invention has a base unit 10 for load-bearing and an open frame structure 11 which is releasably connected to the base unit 10. The base unit 10 itself can be pallet-shaped, which can be easily lifted, for example, by a forklift truck. The dimensions between the base unit 10 and the vertical frame members 12 of the frame 11 were chosen so that a standard size 13 pallet can be placed on the base unit 10. On the pallet 13, which is positioned between the frame members 12 of the open frame structure 11, the load-bearing base unit 10 may have irregularly shaped pieces, such as frozen, split sheepmeat or the like, in the storage space bounded by the frame members 12 (still open and top open) (Figure 2).

In the present case, the wrapping is carried out after loading, for example according to the invention, the load-bearing base unit 10 can be rotated, for example, on a rotating plate 15, while the tensionable wrapping foil 16 can be wrapped around the load as shown in Fig. 3. The wrapping foil 16 may be any commercially available film, such as a self-adhesive extensible film, for wrapping the meat cargo surrounded by the frame structure. Thus, the load can be tightly wrapped at least along its vertical circumference. Following the above wrapping operation, the open and temporary frame structure 11 can simply be removed from the base unit 10, as shown in FIG. 4, thereby releasing the solidly wrapped cargo on the pallet 13, i.e. the finished unit package, which is known by the pallet 13 in a manner known per se. for example, can be transported using a fork lift and can be loaded into a storage container for example.

Preferably, the pallet 13 may also be provided with the horizontal sides of the load, i.e., the load may also be wrapped on the horizontal surfaces, thereby forming a fully enclosed unit load. Irregularly shaped products, such as split sheep and beef, can be stored or transported in whole or in part using the present invention. Thus, if the open frame structure 11 is removed from the base unit 10, the carcass is cut tightly on the pallet 13. After removal of the frame structure 11, the packing foil 16 keeps the load in a sufficiently compact manner.

Although it has been emphasized above that the above-described version of the present invention is for the storage and transport of irregularly shaped products, especially frozen carcasses, it should be noted that the method and apparatus of the present invention are for the storage and transport of any goods, packaged or unpackaged pieces or bulk goods. applicable. Furthermore, the invention is well suited for the transport and storage of goods over and over the sea.

The wrapping technology of Figure 3 was used for the turntable 15, but it can be solved in many ways. For example, the wrapping operation may be carried out by means of a suitable rotary or swing arm (not shown) on which the wrapping film of the wrapping foil 16 is wrapped.

HU 217 568 éhez for the described, effective wrapping of the cargo. This wrapping operation may also require, to a lesser degree, manual intervention.

Figure 4 shows that the open frame structure 11 can be modified to allow for easier removal of the base unit 10 and good access to the wrapped load. In the first embodiment illustrated, four vertical frame members 12, which are joined by cross-ties 12a (Fig. 1 -3), were used. However, these cross-ties 12a may be omitted, if necessary.

Figure 5 shows a further embodiment in which the open frame 11 is formed by bars 20 having a telescopic structure, the lower end of which is connected to the base unit 10 of the load carrier. The rods 20, in their withdrawn position, will provide a storage space in which irregular products can be placed on the pallet 13. After the wrapping operation shown in FIG. 3, these rods 20 can be pushed into the base assembly in a composite manner, i.e. removed from the package, and then placed by the pallet 13 into a simple transport vehicle.

6 and 7 show a very simplified version of the open frame structure 11 of the apparatus according to the invention, in which the support frame 32 is welded from the lateral and upper pipe sections 33. The open frame structure is a substantially rigid structure that is practically not expandable. The pipe sections 33 form an open roof 34 and two side sections 36 and 37 spaced apart. The lower portions 38 of the side portions 36 and 37 are triangular in shape and terminate at the apex 39. This shape also facilitates the wrapping of the lower part of the open frame structure 11 with the wrapping foil 41, thereby forming a closed storage space on the side and bottom. Figure 7 shows how the stretchable wrapping film 41 is wrapped around the tube sections 33. Depending on the material used, the wrapping foil 41 can generally be stretched and tensioned between 10 and 400, thereby tightening the tube sections 33 slightly. The width of the wrapping foil 41 is chosen so that a few wraps can be formed in which the layers of the wrapping film 41 overlap each other. Due to the tension in the wrapping film 41, the side frame portions 36 and 37 of the support frame 32 are forced inwardly towards each other. This also facilitates the removal of the "container" formed by the wrapping foil 41 from the support frame 32 after the container has been filled with the material to be stored. The material to be stored can be compacted in the frame structure 11, for example in the case of waste materials. For this purpose, the sub-frame can be placed on another frame structure or support which holds the support frame 32 upward with the open lid 34. Any compression method known per se can be used for compression. For example, a compression weight may be used that may be embedded in the frame structure 11, but any other compression may be involved. Optionally, a compacting machine may be used in which, after clamping the lower portions 38 of the support frame 32, the frame structure 11 can be seen along its outer circumference with the tensionable plastic wrapping film 41 (not shown separately).

Once the "container" is formed from the frame structure 11 wrapped with the wrapping foil 41, after its filling, the frame structure 11 is pulled out of the package, due to the friction between the material and the support frame 32, which is helped by the downward narrowing of the side sections 36 and 37 .

Fig. 8 shows how the wrapping foil 41 working with the pipe section 33 can reduce friction. In this case, the pipe sections 33 are provided with longitudinally extending ribs 42 that keep the wrapping film 41 away from the pipe sections at a distance. At the same time, the bearing surface is reduced, and consequently the friction, as well as the sliding of the charged "storage tank" from the pipe sections 33 is facilitated. Note that the pipe sections 33 may be of any suitable shape and the shape of the ribs 42 may also vary. The ribs 42 may also be made in single pieces with pipe sections 33, but may also be manufactured as separate pieces which are then fixed to the pipe sections 33 for minimum friction. However, it is also possible for the pipe sections 33 to be provided with rollers, an endless belt or other units to facilitate friction reduction to facilitate removal of the charged "film container" from the frame structure 11. The wrapping film 41 preferably wraps the support frame 32 at a height higher than the intended filling height, so that more film layers are placed above the load. After removing the filled "foil container" from the support frame 32, the top layers of the wrapping film 41 contact the upper portion of the deposited material. These upper edges can be joined together to seal the "foil container" tightly on top.

Optionally, the wrapping film 41 may be coiled so as to prevent leakage or loss of the deposited material, such as a flowable small particulate material. Optionally, a cover sheet may be placed on the surface of the deposited material prior to uncoupling the "foil container" from the frame structure 11 to cover. Since the tensionable plastic wrapping film 41 generally has a self-adhesive property, i.e. its layers adhere to one another, the storage container formed by it can also be regarded as liquid lumps, which may be advantageous, for example, for wet granular materials. The bottom of the "container" can be formed by winding the wrapping film 41 around the lower portions of the support frame 32. However, care should be taken not to allow liquid to enter the "foil container" that could damage the film material.

Figure 9 shows a version of the support frame 32 of the open frame structure 11, wherein the open roof 34 is a circular frame member 44 which is fixed to the bottom circular frame through the downwardly extending side members 46. When wrapping the wrapping foil 41 around the side members 46, the side members 46 receive the inward tension as shown in Figure 9.

EN 217 568

The load-bearing base unit 30 is formed of a liquid-proof material, depending on the fluid flow to be stored. The base unit 30 has a bottom disc 30a provided with a cylindrical flange 30b. The load-bearing base unit 30 is made of a material which, when in use, seals the wrapper wrapped from the wrapping foil 41 tightly from below. Optionally, the open frame structure 11 and the load-bearing base unit 30 may also have a different configuration, such as rectangular. The combination of the open frame structure 11 and the base unit 30 may include square frame elements (equivalent design of the frame members 44 of FIG. 9), and may optionally have a square base unit 30. Such a frame structure requires downwardly facing frame members only at the corners of the square, but may also have additional downwardly facing side members disposed along the sides of the square frame element. The wrapping film 41 is wrapped around the releasably fixed frame structure 11 and the base unit 30. This rounding is preferably carried out in a plurality of layers (preferably in 5-10 layers) along the circumference, in which the individual layers overlap each other, in particular around and below the circumference of the base unit 30, thereby even securing the frame structure 11 to the base unit 30 itself. . The wrapping of the wrapping film 41 is preferably carried out from the bottom upwards in a spiral shape up to the top of the frame structure 11. After filling the so-called "foil container" with the material to be stored, the frame structure 11 can be lifted, i.e. it can be pulled out, and then the layers of film overlapping the load tightly and tightly seal the load.

It is emphasized that the present invention can be used in various forms and for various purposes. For example, "storage tanks" made using the present invention may also be used for storing bulk materials, such as fertilizers, fibrous materials, such as wool, or any other bulk material. Since the "storage container" with the extensible plastic film can be easily formed by simple winding of the open frame structure 11, the storage method according to the invention is very well suited for household waste, commercial or utility waste as well as for storage or storage. Since the extensible plastic film is substantially cheaper than commercially available waste collection bags, the use of the present invention results in a substantial cost reduction. Furthermore, the waste material can be safely stored by the use of the present invention so that it can be handled easily by hand or by machine.

Fig. 10 illustrates a further exemplary embodiment of the temporary support device according to the invention having an open frame structure 51 and a base unit 52 for lifting the load. In the present case, the open frame structure 51 has four pegs 53, which are arranged in pairs on both sides, and are joined by cross members 54 on the top. The lower ends of the suspension rods 53 fit into the openings 55 of the load-bearing base unit 52 and are releasably fastened so that the open frame structure can be lifted from the base unit 52. Any releasable connection between the suspension rods 53 and the base unit 52 is possible. At the top of the frame structure 51, a further cross member 56 is fastened, for example, the fork of the fork-lifting machine can be fastened and the frame structure 51 can be lifted from the base unit 52, for example.

In the present case, the base unit 52 has two-sided legs 57. Their height is selected so that for example a fork lifting fork is placed below the base unit 52 to lift the entire load loaded with the carcasses.

For example, for splitting of carcasses using the apparatus according to the invention, it is placed on a base unit 52 which is releasably fixed to the open frame structure. Fig. 58 shows a pallet 58 onto which carcasses are then placed. The number (and size) of carcasses may vary, however, it is advisable to have the carcasses underneath. FIG. The "storage space" bounded by the open frame structure 51 is generally 1.2 általában 1.2 m wide and 2 m high, according to our experiments, in which a carcass of 0.6 tonnes can be stored. In order to accommodate different sizes of carcasses in the "storage space" delimited by the frame structure 51, different loading or stacking shapes can be used. For example, it may be advantageous to have a design in which the width of the open frame structure 51 can be adjusted. This can be accomplished by forming a series of openings 55 in the base unit 52 and connecting the suspension rods 53 to the cross members 54. The adjustable frame structure 51 provides a way of adjusting the width dimension for the different size of carcasses, so that the head-to-foot stacking arrangement can be used even more well. These measures reduce the width of the package and make its shape more regular.

As soon as the loading into the "storage space" bounded by the open frame structure 51 is completed, i.e. the cargo is completed from the carcasses, the base unit 52 is lifted together with the load on it and the pallet 58, and the frame structure 51 fixed to the base unit 52, for example, by a forklift truck and a spiral. a rotating plate 59 of a wrapping machine 60 capable of winding, as shown in FIG. During the rotation, the wrapping film C is wrapped around the load, as described above. The wrapping film C is threaded threaded, i.e., in a spiral, around the load rotated by the turntable 59, and is thus packed tightly. In the present case, the wrapping film C can be biased in two directions (for example by means of a device known as WRAPMAN).

Thus, in the packaging operation shown in Figure 12, the wrapping film C also surrounds the pegs 53 of the frame structure 51. The properties of multilayer wrapping and plastic wrapping film C provide a tension that alone

As a result of this, packaged carcasses become self-supporting in nature, and even withstood loads during loading and transport operations. According to our experimental experience, a four-layer coating was very effective when approximately one-third and two-thirds of an additional coating layer was used. As a packing film C, we used a high-strength tensile film, for example, 100% linear low density polyethylene (LLDPE) having a thickness of about 35 microns. Generally, around 25 revolutions were required during packing.

It may be advantageous to wind the spiral in the form of a coil, but it is also possible to use parallel overlapping coils or combinations thereof. The parallel strip width may be, for example, between 0.5 and 2.5 meters, but for spiral winding, the film width may be, for example, between 0.3 and 0.5 meters. Upon completion of the wrapping operation, the frame structure 51 is pulled vertically out of the package, whereupon its suspension rods 53 slip out of the space between the load and packing foil C, as illustrated in Figure 13. Despite the fact that the wrapping film C has an adhesive property and that it is sufficiently tensioned on the load during winding, the hanging beams 53 of the frame structure 51 can be pulled up relatively easily. To achieve a low coefficient of friction, the studs 53 of the frame structure 51 may be provided with a friction-reducing coating (e.g., a polytetrafluoroethylene-teflon coating). In the embodiment of Fig. 10 of Fig. 51, two pendulum bars 53 are used on both sides, which may, however, be replaced by a wider flat hanging member. However, more than two pendulum bars 53 may be used and may be arranged along three sides. Furthermore, instead of withdrawing, lifting the open frame structure 51 from the package, cross members 54 and 56 or corresponding equivalent connecting elements and the frame structure 51 can also be removed so that the load itself can be lifted out of the frame structure 51. It is also possible, however, that the suspension rods 53 of the frame structure 51 are connected to the pivot. This allows the upper half of the frame structure 51 to be lifted after wrapping around the wrapper, and the load can be lifted from the remaining bottom portion.

A number of other embodiments of the temporary support device according to the invention are also possible, with only a few exemplary embodiments illustrated in the drawings. Although a lifting device is mentioned as a lifting device in the first exemplary embodiment, a permanently installed device may be provided with its own lifting device.

Figure 14 shows a self-supporting and shape-retaining package according to the invention. The package on the pallet 58 is easy to handle and move, for example, using a forklift truck. Such packages can be stored in meat processing plants, but naturally, there is a need for proper cooling in the case of carcasses for longer-term transport or longer-term storage. For loading the cargo packed according to the invention into the ship, the packages can be easily lifted and moved by the pallet 58. As these packages are suitably uniform in size, the available load space can be utilized as efficiently as possible. Thus, the otherwise irregular size and shape of carcasses in unit packets can be easily and easily handled, thereby significantly reducing costs and increasing storage and transport efficiency.

11-14. Figs. Optionally, the same pallet may be used as well. This makes it possible for the packages to be stacked on top of each other, or to be trapped on top and bottom during loading. Pallets 58 do not necessarily have to be conventional wood structures, such as lightweight pallets, which can be manufactured, for example, from cardboard or cardboard tubes. It is preferred that the shape of the pallet 58 be adapted to the shape of the base unit 52 so that, upon insertion, they are forced into one another.

Fig. 15 shows a further exemplary embodiment of the temporary support device according to the invention, the various operating positions of which are shown in Figs. FIGS. In this case, the load is placed horizontally and not vertically at loading, as shown in Figures 10-14. FIGS. In this embodiment of the temporary support device, the open frame structure 61 is pivotally attached to the base bearing 60A. The horizontal frame bars of the open frame structure 61 also form a load-bearing base unit 62 (FIG. 15), which are provided with vertical frame rods 63 at their ends. The base unit 62, which is united with the open frame structure 61, engages with the pins 60A by means of pins 64.

In use, the frame structure 61 is first in its initial position as shown in FIG. In this case, pallets 65 are placed on the base unit 62, and the price to be packed is packaged as described above, and then additional pallets 66 are placed on the sides of the load (Figure 16). The frame frame 61 and the pallets 65, 66, as well as the space bounded by the base unit 62, thus serve as a "cargo space for example for carcasses". After loading, as shown in Figure 17, the load is wrapped around a tensionable plastic wrapping foil 67. During the next operation step of the apparatus, the frame structure 61 is tilted together with the load from the horizontal position of the original to the vertical position around the pins 64 (Fig. 18), for example by means of a non-illustrated hydraulic cylinder or other mechanical tilting device. The direction of tilting is indicated by X in Figure 17. The package now in the upright position is removed from the frame structure 61, and then wrapped around the wrapping foil 68 as a horizontal package, e.g. FIGS.

The 16-18. Figs

HU 217 568 Β can be made of longitudinally split cardboard tubes and, for example, wooden cross-ties. Of course, any other version can also be used as a lightweight pallet.

See Figures 19-21. Figure 1 shows a further exemplary embodiment of the temporary support device according to the invention, which can also be used, for example, for wrapping carcasses. This consists of an open frame structure 71 formed of a load-bearing base unit and vertical frame members. The height of the frame structure 71 may be equal to 10-14. Figs. Optionally these rods of the frame structure may be shorter, thus creating a half-unit packet of goods that will be discussed in more detail below. In the space delimited by the base unit 70 and the open frame structure 71, pallets 72 (Fig. 19) are laid on which the carcasses are then loaded (Fig. 20). The cargo is wrapped around wrapping foil 73, for example by a spiral winding machine. By circular winding, we create a half-unit packet, which in itself is sufficiently stable. This half unit package is then removed from the structure in the direction indicated by Y (Figures 20 and 21) to which a fork lift can be applied.

Figure 22 illustrates how two such sets of half units can be stacked together to form a single standard size unit packet. To do this, a multi-wrap wrapping strap of 74 wrapping foils is provided, the purpose of which is to connect the two half unit packets to each other. The advantage of this unification is that it is often more advantageous for users at the destination to divide the unit packets into parts of a smaller number of carcasses.

Finally, the 23-25. 1 to 3 show an exemplary embodiment of the temporary support device according to the invention, the open frame structure 81 of which in the present case consists of only two U-shaped brackets, the legs of which in FIG. 23 also serve as load-bearing base units 82, and their vertical legs form supporting frame members. During use, first, at least one side of the frame structure 81, pallets 84 are placed on the frame members 83 (Figure 23). Then, for example, carcasses are placed in the space between the pallet and the opposite frame members 83 and wrapping is carried out by wrapping 85 packing foils (Figure 24). Then, as shown in Figure 25, the package is turned to the side with the load, and the frame 81 is laterally withdrawn. The package can then be wrapped in a vertical direction with the wrapping foil. This package can also be a whole or a half unit package.

Finally, it should be noted that FIGS. Figs. Figures 71 to 71 may also be telescopic, so that they can be telescopically folded in the base unit (e.g., as shown in FIGS. 10-14) or upwardly into a top plate after the package is made. Such telescopic rods or rods may also be pneumatically or hydraulically actuated. The wrapping with the wrapping film can be done before and / or during the loading of the material and / or depending on the nature of the material. If the packages are not placed in a chilled space, the packaging film may be provided with a heat-reflecting metallic coating to prevent their heating, or a light coloring agent may be mixed into the plastic. In order to limit the heating of unpackaged packages due to convection heat flow and to increase the protection of the load against injuries, an additional casing is used from the layers of air bubbles (for example, it can be made by vacuum forming from a plastic film) as exemplified in Figures 26-28. FIGS.

Fig. 26 illustrates a bag of air bubble layers 90, which is pulled onto the package 91. For example, the bag 90 may be secured with an additional layer of wrapping foil. Optionally, the amount of air bubble film used can be reduced by applying adhesive 92 straps on one side of the package 91. In places subject to increased risk of injury, such as corners, sides, stronger and more resistant material, film material can be used. For example, at least the exterior of the air bubble film should be colored white, for example. It is particularly advantageous to indicate the upper portion of the unit packet. An even better effect can be achieved if the two insulation methods (i.e., pigmented or metal foil wrapping film and the colored, air bubble film) are used in combination. These additional packing costs will be reimbursed, as this will remove the currently used additional bags and pads. Finally, removable covers may be used for unit packages made in accordance with the present invention to better protect the load from environmental influences, which can then be removed and reused after loading into the ship.
