Method and device for storage of cheese

The invention relates to a method for storing cheese. In addition, she is concerned with a device suitable for this purpose. .. · - - ■ ■ ■ ·

To keep the quality of stored cheese as high as possible,., the cheeses should be turned regularly. So far took place This is often done by hand, with the cheeses being picked up and turned one by one, as there is still no satisfactory solution for the mechanical execution of this turning process. Of course, this manual treatment requires one large amount of work, whereby the work is also arduous and the storage takes up a relatively large space, since all cheeses have to be easily accessible.

509810/0285

The invention now aims to provide a method for storing To create cheese, at least turning the cheese mechanically can be done. For this purpose, it is proposed according to the invention to proceed in such a way that the cheese is in a frame in several layers on top of each other in the individual layers lying boards are placed so that the respective board layer is transverse to the longitudinal direction of the boards for turning is shifted over an amount that is approximately equal to the width of a board, so that a board with cheese after outside of the scaffolding, whereupon the scaffolding When the cheese is pushed out, an empty board is placed, then the two boards with the ones in between Cheese turned 180 ° and into another. Height than the original Height of the pushed out board are brought, whereupon finally the board with cheese in this is pushed back into the scaffolding at a new height.

This process enables the cheese to be made mechanically to turn, being proportionate to a given space many cheeses can be stored.

A particularly useful device for implementation this method is designed so that it has a framework in which cheese boards lying next to and on top of one another are arranged displaceably transversely to their longitudinal direction, with a lifting device on both sides of the frame

Pig. 10 shows a section through the mechanism according to FIG.

The one in the Pig. 1 and 2 shown cheese storage system consists of a number of vertical columns 1, on which horizontal, U-shaped beams 2 are attached. From Pig. Figure 2 shows that the beams 2 support the ends of boards 3 which the cheese 4 can be placed. It can be in any horizontal Layer a large number of boards 3 are arranged side by side, with Pig. 2 shows that a big one Number of layers can be provided one above the other. The length and height of the vertical columns 1 and the horizontal bar 2 assembled scaffolding depend on the available space and the required storage capacity away.

After Pig. 1 is a lifting device on the left side of the frame 5 and a lifting device on the right side of the scaffolding 6 combined with a tilting device 7 attached. The lifting devices are horizontal, pneumatic Adjusting cylinders 8 provided and in vertical

5098T0YO285

Direction along near the side edges of the scaffolding, vertical pile pillars serving as guide axes 9 movable. The lifting devices 5 and 6 are so with each other coupled so that they are always at the same height.

When the two lifting devices 5 and 6 are at the level of a board layer 3 present in the scaffolding, a board that is present in the scaffolding and possibly loaded with cheese can be pushed into the scaffolding by means of the lifting devices 8 by means of the lifting devices, with all boards the layer in question are offset over a distance that corresponds approximately to the width of a board. As a result, a board is pushed out of the frame and into the combined lifting and tilting device 6, 7 at the right end of the frame. From the following description of the combined lifting and tilting device it emerges that this Yorrichtung generally already contains a board that extends over the inserted cheese. If desired, the cheeses can then be turned so that they come to rest on the board already present in the combined lifting and tilting device, whereupon the two lifting devices are brought to the level of another board layer. By means of the other adjusting cylinder 8, the turned cheeses from the combined lifting and tilting device 6, 7 are pressed into the frame, whereby another board with cheese is pushed into the lifting device 5 on the other side of the frame. The two lifting devices 5 can then be moved back to the level of the original board layer

509810/0 285

whereupon the whole cycle can repeat itself. It stands to reason that in this way board after board is layered all cheeses can be turned, with the use of suitable organs the different movements can be done completely automatically.

The combined lifting and tilting device is in Pig. 3 to shown in more detail. The combined lifting and tilting device has two construction parts lying one on top of the other near the two ends 10 and 11, which are connected to each other by further structural parts 12 and in which .die longitudinal the vertical hollow columns 9 displaceable bearings 13 housed are. The lifting device is by means of a vertically displaceable strip 14 with a vertical Displacement-causing lifting chain coupled. A rod 15 is attached to the strip 14, which over a part its length is surrounded by a compression spring 16 (see Fig. 6) between a fixed point of the frame of the lifting device and a plate supported on the rod 15 by nuts. Furthermore, there are two on the strip 14 Arms 17 extending obliquely downward are articulated via a pin 18. With the free ends of the arms 17 are by means of horizontal Pins 19 are coupled to supports 20, to which brake blocks 21 which can be slid along the vertical columns 9 are attached are.

509810/0285

2439184

It can be seen that in the event of the breakage of a lifting chain attached to the upper end of the strip 14 ″, each 16 seeks to pull the strip 14 and the pin 18 attached to it downwards, whereby the two brake blocks 21 after outside against the pillars 9 are pressed so that -avoided that if a lifting chain breaks, the lifting device slips down.

Bearings 22 for receiving axles 23 are attached to the frame parts 11. At the ends of the axles 23 facing one another panels 24 are attached to each other by beams 25 are connected. On the facing sides of the plates 24 U-shaped profiles 26 and 27 are attached, the Cross-section at least approximately corresponds to that of the U-shaped profiles. According to Fig. 5 is at the left end of the upper profile 26 a stop 23 and at the right end of the lower profile 27 a stop 29 is provided.

Furthermore, two axle journals 30 are provided on each plate 24 near the bottom and the top, around which three arms-31, 32nd and 33 existing levers rotatable s-ind. Between the free end of the arm 31 and a fixed point of the neighboring one Plate 24, a tension spring 34 is provided. At the free At the end of the arm 32, a roller 35 is attached, which with a relation to the frame parts 10 and 11 occupies a fixed position Cam 36 is in operative connection.

5098 10/0285

Between the free ends of each pair of mutually associated arms 33 is horizontal (between the plates 24) a bar 37 is arranged. Also at the end of each arm one end of a coupling piece 38 is articulated, the other end of which is articulated on a slider 39. In the slide an elongated hole 40 is provided, in which horizontal pins 41 attached to the plates 24 lie, so that the slider 39 is displaceable relative to the plate 24 in the vertical direction.

Near one end of the combined lifting and tilting device a motor 42, which drives a chain wheel 44 via a reduction gear 43, is attached to the frame parts 10 to 12. The chain wheel 44 is connected by a chain to a chain wheel 45 attached to an axle 23.

When the system is put into operation, it is ensured that a cheese board 3 is present in the upper beam 26. From Fig. 5 it can be seen that in this state of the system the one on the left side of the combined lifting and tilting device Bar 37 is approximately at the level of the upper cheese board 3. This cheese board 3 is also between the attacks and on the (in Fig. 5 upper) sliders 39 fastened tabs 46 locked.

If the lifting devices are adjusted so that the U-shaped beams 27 at the height of a set of U-shaped

I ^{1 For} the mechanical supply of the wheat to the framework, preferably that in the pig. 7 and 8 used auxiliary device shown schematically.

Pig. 7 shows a partially curved roller track 47, the curved part of which along part of the circumference is one by one vertical axis rotatable turntable 48 extends. The curved one The end of the roller conveyor 47 connects to an endless conveyor belt 49. On the outer circumference of the turntable 48 are in Equally spaced radially projecting arms 50 with rollers 51 freely rotatable about vertical axes are attached.

The cheeses 4 are fed one behind the other via the roller conveyor 47 (see Pig. 7) and the turntable is driven in time with the endless belt 49. Got during this rotation between two successive cheeses 4. each one carried by an arm 50 roller 51, whereby the cheese in regular Time intervals fed to the running conveyor belt 49 will.

From Pig. 8 it can be seen that the conveyor belt 49 is parallel runs to the cheese boards 3 lying in the frame. During normal operation, at a given point in time, the Conveyor belt 49 a certain number, in the present case six, cheeses, with the desired space between the cheeses is available. In order to be able to place these cheeses on a board 3, a frame 52 is located above the conveyor belt 49

arranged, along which a trolley 53 transversely to the longitudinal direction of the conveyor belt 49 and the cheese boards 3 back and it can be moved here.

The trolley 53 has one to the conveyor belt 49 and cheese boards parallel bar 54, on which horizontal, circular plates 56 "are attached. When the trolley 53 is attached to the The bar 54 stands above the conveyor belt 49, as is shown by dash-dotted lines in FIG. 8 the plates 56 move downwards by means of the adjusting cylinders 55 until they come to rest on the cheeses 4. Thereon a negative pressure is generated under the plate by lines not shown, so that the cheese on the plates 56 get stuck when the plates 56 are raised again. Then the trolley 53 to the left (in Fig. 8) in the position indicated by full lines, whereupon

* - ■ ■ ■ ■

the plates 56 with the cheeses attached are lowered until the cheeses on one in a lifting device to the outside of the frame displaced board 3 are, whereupon the vacuum is released, so that the cheese 4 from the Loosen panels 56 and rest on board 3. Then the loaded board 3 can in the above Vieise in the scaffolding and from another layer of the scaffolding again an empty board can be pushed into the relevant lifting device, while in the meantime by means of the Trolley 53 new cheeses 4 are picked up by conveyor belt 49.

5098 10/0285

It is evident that in this case too the different Movements can at least for the most part be automated so that they all take place in the correct sequence without the intervention of operators.

To remove the cheese 4 from the boards 3 can, for. B. close the underside of the scaffolding a bar parallel to the boards can be arranged, which adjust in two positions leaves, namely a first position in which he is seen in the sliding direction of the boards just under a layer of Boards, and a second position in which he is is located roughly in the middle between two boards lying on top of each other. Usually the bar becomes the first position in such a way that it does not interfere with the introduction and removal of cheese-bearing boards. For slimming the cheese from the boards, the beam is put in the second position. If now a board lying in the lifting device is pushed into the frame with cheese, the insertion of the board is not hindered, the cheese becomes but held back by the bar in the second position and thus pushed off the board. To the Catching the cheese is under the tilting mechanism on the frame parts 11, preferably at an angle away from the frame downward guide member, e.g. B. in the form of rollers, which the cheese further guide organs and / or conveyor belts to divert the cheese.
