METHOD AND APPARATUS FOR STORING PAPER ROLLS -FÖRFARANDE OOH ANORDNING FÖR LAGRING AV PAPPERSRULLAR

The present invention relates to a method for storing paper rolls in a warehouse where the paper rolls are imported and stored on top of each other and taken for further processing.

A known method and apparatus of this type is disclosed in Finnish patent application 864705. The object of the invention is to further develop this method and apparatus.

The method according to the invention is characterized in that the actuator has a separate transport carriage, with which the roll of paper is transferred from the actuator to the elongate shelving passages of the warehouse and back from the warehouse to the actuator. By means of the invention, the storage space can be used as well as possible in the height, depth and lateral directions. Thus, for example, in the depth direction of the shelf corridors, the shelf can accommodate more short rollers and correspondingly fewer long rollers in the same corridor, so that the utilization rate of the warehouse can be optimized. The computer calculates and optimizes the utilization rate.

A preferred embodiment of the invention is characterized in that the paper rolls are brought into storage by a forklift. in the formula in the position of the insertion station, from which the actuator transport carriage rises one or more rolls at a time and takes it / them to the actuator which travels to a designated storage location and the transport carriage takes the load (s) to a storage shelf in a predetermined type of paper. When the rolls of paper are handled in this way in a position lying through the entire warehouse, it is very unlikely that they will be damaged and the scrubber corridors can be used to best advantage. Rolls of paper of the same size are always placed in one and the same jet corridor reserved for them.

The invention also relates to an apparatus for carrying out the method described above. The apparatus includes a storage actuator, such as a jet elevator, with which the rolls of paper entering the warehouse can be placed in the warehouse and removed from the warehouse for further delivery to the drive. The apparatus according to the invention is characterized in that the warehouse consists of elongate shelving corridors known per se, in which a transport trolley belonging to a shelf lift can be transported for storing and removing paper rolls. By means of the invention, the storage space can be used as well as possible in terms of height, length and side. In this way, the warehouse 1 with its equipment can in principle be built in any space.

An embodiment of the invention is characterized in that the carrying table of the hoist elevator can be pivoted 180 ° about its vertical axis so that the conveyor carriage on it can be pivoted so that the transport fork, i.e. the front part of the carriage, can pass above the carriageways on both sides. In this way, the transport trolley is made to travel to two separate anti-theft carcasses on both sides of the frosting elevator.

Another embodiment of the invention is characterized in that the scrubber corridors have U-shaped rails connected to each other by a downwardly curved intermediate plane, on which a roll of paper can be placed for storage and on which U-shaped rails the wheels of the transport trolley run. its own weight cannot damage the circumferential layer of the roll during storage - .. r.in, because the bearing surface of the roll is large enough.

The intermediate plane, i.e. the base, can also consist, for example, of a strip-like material or the like which can withstand high tensile forces and which is attached to the support wall. Due to the weight of the paper roll, an elastic deformation occurs in the substrate such that the substrate conforms to the circumferential shape of the paper roll.

il. SU.i ϋ.Ιϋ. . .3 97209 The elasticity of the retaining wall itself has also been utilized here.

Another possibility is, according to the features of claims 8 to 10, to provide an elastic steel plate as a substrate, which is made thin to achieve the desired elastic deformation and the circumference of the paper roll, respectively. Since the base plate is substantially only affected by traction, a relatively thin plate can be used in this solution.

The features of claims 12 and 13 show structural simplifications and the possibilities to provide in a simple manner the desired adaptation of the substrate to the circumferential shape of the paper rolls. The features of claim 15 avoid folding the base at the support wall.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which

Figure 1 shows a top view of the warehouse.

Fig. 6 shows a section according to Fig. 5, but of another embodiment of the busbar.

The warehouse is filled with a forklift by bringing one or more rolls of paper at a time to the entrance station 4, where the rolls are lined up in succession. The rollers are brought to a lying position. At this point, the roll dimension data and the paper 1 aatuti edot are automatically read from the barcode into the memory of the warehouse control system or the data is manually reported by the truck driver with the switch. The transport carriage 3 belonging to the waste carriage 2 takes the paper roll as it enters the waste carriage 1, which further transports the transport carriage and the paper roll on it to a specific place in the warehouse where the transport carriage 3 leaves to take the paper roll to the corridor. Shelf corridors are filled in this way with paper rolls. When the drive needs a specific paper roll, the shelf elevator first retrieves the correct shelf aisle, after which the transport carriage 3 retrieves the paper roll from the shelf aisle, delivers it to the shelf elevator, which further takes the There are two adjacent flake blocks in the warehouse, between which the shelf lift runs. The carrying table of the hoisting elevator can be pivoted 180 ° about the vertical axis so that the transport carriage 3 on it can be pivoted so that the transport fork, i.e. the front part of the carriage 3, is made to pass into the carriage corridors on both sides of the hoisting elevator. The carriageways have U-shaped rails 6, which are connected to each other by a downwardly curved intermediate plane 7, on which a roll of paper can be placed for storage, and on the U-shaped rails of which the wheels of the transport carriage 3 run. When the rolls of paper are handled throughout the warehouse in a lying position, there is no risk of tipping over, which is often possible when the rolls are stacked vertically on top of each other. The method and device according to the invention provide the best possible storage capacity.

As shown in Fig. 5, which shows only the left profile 7 of the guide rail 4 - the corner profile 8 is formed mirror-symmetrically with respect to the plane of symmetry 24 - the corner profile 7 consists of a U-profile with a high retaining wall 9 on the side facing the second corner profile, which is higher than the second jaw 25. The corner profile 7 and the second, not shown, corner profile 8 are fixedly mounted on the bottom 26 of the storage shelf 3. According to one embodiment, the material of the corner profiles 7 and 8 is a steel plate.

The corner profile 7 is provided at the upper edge of the support wall 9 with a base projection 14 formed by bending the upper edge of the support wall 9. The base projection 14 is directed towards a second, not shown, corner profile 8. And to the upper part of the support wall 9, for example, the bent edge 12 of the plate 10 is fastened with screws, which plate consists of an elastic steel plate thinner than the material of the angle profile 7. At the plane of symmetry 24, the plate 10 has a fold 16, which is formed so that two equal sub-areas 10a and 10b join at an obtuse angle Oc of about 170 °. In the middle of the guide rail 4 thus formed there is thus a base 10 for a roll of paper 2. Fig. 5 shows that the elastic plate 10 is formed by the weight of the paper roll 2 and that then the support wall 9 is also subjected to a certain deformation in its upper part 9b. When the paper roll 2 ·· is placed, the weight of the paper roll causes the substrate 10 to conform to the contour 27 of the R-diameter paper roll. The same happens when a paper roll with a smaller diameter R 'is placed, where both the plate 10 and the support wall 9 have a greater deflection than the larger diameter roll. In any case, the desired adaptation of the substrate 10 to the shape of the circumference 27 or 28 of the paper roll takes place. The circumferential support surface of the paper roll 2 is thus so large that flattening or undesired deformation of the outer circumference of the paper roll 2 does not occur.

It is also possible to provide, instead of the steel plate 10, a mat with sufficient tensile strength, made of textile material or plastic, which is substantially stressed only by the tension caused by the paper roll 2 stored on it. Such a mat may also be suitable for forming a substrate.

Fig. 6 shows that the fastening of the base 10 ', which base can again consist of a plate, can be realized in a very simple way so that the outer edges 12' of the plate 10 'are correspondingly bent and connected through a stepped projection 13, which protrudes outwards from the swimming profile 7. 'towards the second claw 25'. By bending the outer edge of the support wall 9 ', a base projection 14' analogous to the protrusion 14 of Fig. 5 is created, which transmits an undesired deformation of the plate 10 'in the base area to the support wall 9'. The design of the folded plate 10 'is otherwise analogous to the embodiment of Figure 5. Of course, making a fold 16 can also be avoided. However, this embodiment has the advantage that the first contact of the paper roll with the substrate 10 takes place not only in one but in two places. Unwanted adverse effects on the circumference of the paper roll can thus be avoided.
