Description

Cheeses nowadays are used against superficial changes, especially mold, among other things Protected by a cover, which consists of an impermeable, flexible application material and is closely attached to the wheel of cheese to be protected. Devices for applying the coating are known in various designs. So is for the purpose of even distribution an application material made of plastic has been proposed, the liquid plastic on the cheese loaves to be applied by rolling and mutual smearing (German patent specification 1 099 251). Here However, difficulties arise because the plastic solutions that can be used do not dry as quickly, so that the treated cheese wheels contaminate the latter when they are placed on a base and, under certain circumstances even stick to her. To avoid these disadvantages, a device has become known, in which the coating is first applied to one side with the help of a friction roller and after drying this side is applied to the other side. The disadvantage of this type of applying the coating to the cheese wheel, so that the cheese wheel must be treated twice.

For coating cheeses with an impermeable, flexible application material in one Operation is a device known that a conveyor with a plurality of endless chains with the formation of an upper and lower run (US Pat. No. 2,695,590). Under this sponsor this device has several containers that the application material in the liquid state or a Contains liquid to solidify the coating when immersed in this liquid. The ones to be treated Cheeses are impaled by hand on a grid with several pegs. That with Several loaves of cheese are attached to the grating in the lower run and from this as a result of multiple deflections of the chains immersed in the various containers. After the coatings on the Cheese wheels are solidified, the grids are removed by hand at the end of the lower run and the Loaves of cheese pressed down from the pins of the grilles. The empty grid is again made by hand hung in the conveyor and via the upper run the beginning of the device for reloading returned with cheese loaves. With this device, the cheeses are in one operation provided with a coating, but the places where the cheeses are skewered on the tips remain were without a coating. Another disadvantage of this device is that for actuating the device several people are necessary.

In order to be able to easily remove the latter from a cheese wheel with a coating, it is known in the Coating to embed a thin and elastic band in a plane of symmetry of the cheese wheel, its with the application slipper-soaked ends protrude on the outer surface of the coating. A method for Manufacture of such a coating with embedded tape is in the French patent 1 388 048. The method consists in pounding the cheese with a section of a thin To wrap around a band, which has the shape of a U, and its length is considerably greater than for this Looping is necessary to hang up the cheeses by means of this U-shaped belt To coat cheeses with the application substance and after it has solidified the two over Cut off the cover protruding tape ends where they are no longer with the application material are soaked.

The object of the invention is to provide an automatic apparatus ¹ for performing this method.

The invention relates to an automatic device for applying a thin and elastic band

ίο on two flat, parallel surfaces having cheese, loaves in a plane of symmetry perpendicular to these surfaces and for covering the cheese loaves with an impermeable, flexible application material, from which the ends of the application material with this soaked tape survive freely. The invention. is that the device is one in itself known conveyor with a plurality of endless chains that the conveyor in parallel, Horizontal runs arranged in perpendicular planes

so possesses, which gives a uniform motion and which are provided with transport grippers at regular intervals. Under this sponsor are one behind the other devices for feeding and holding the cheese loaves under transverse ones Transport grippers, devices for continuously looping the cheese loaves with the transport grippers attached loops of continuous belts, a known per se, the application fabric Application container in the liquid state, pairs of scissors, a container for solidifying the cheese coating and a device is arranged which consists of the transport grippers after the cutting removes tape waste carried by this. This is for easy changing of the order container designed to be vertically displaceable. A drive arrangement drives the chains with their transport grippers, the devices for feeding and holding the cheeses, the devices for the continuous Wrap around the cheeses and the pairs of scissors. According to the preferred embodiment According to the invention, the conveyor has two chains in which chain links are evenly spaced are connected by cross braces. On these cross struts is a row of grippers with double Clamping effect arranged for the simultaneous treatment of several wheels of cheese, the number of which is the same which is the transport gripper carried by a cross strut. Each feeding and holding device contains on the one hand, a supply gripper, which a loaf of cheese fed to the device lying flat grasped at its circumference and tilts upwards, around the flat sides of the cheese loaf in the vertical To bring position, as well as on the other hand a loading gripper, which is on the flat sides of the cheese wheel supported so that it leaves its zones corresponding to its center of gravity free. The loading gripper moves under the conveyor at the same speed as this until it is looped of the cheese is done with tape. Then the loading gripper is opened to release the cheese and then returned to its original position by a translational movement.

The advantages achieved by the invention consist essentially in the fact that the cheese loaves by the device according to the invention automatically with a cover with embedded tape for easy removal of the coating. The coating completely encloses the cheese

constantly with no vacancies. The device according to the invention is also distinguished by a simple, practical structure, so that only to monitor the device a person is required who only needs to intervene in the event of malfunctions.

After it has been applied, the application material forms a tape and, for cutting in three rows D, E, F, forms a coating on the cheese, in which the tape 5 (FIGS. 17 and 23) are arranged. The mechanical loop is embedded, the parts of which are looped freely from the coating for supply, for loading and for protruding ends with this application material, are looped with tape alternately in pairs. The so hung up and covered together, in order to simultaneously serve two rows of cheeses, are then used by the device for serving three. The supply cutting edges of the belts are supplied for this purpose. «· Grab a pair for rows E and F, the

The entire cutting device is then a pair of loading grippers for rows D and E in the state shown in FIG. 23, in which and the rollers for continuously wrapping each pair of scissors is open, as shown in FIG. 14 with a pair of tape for the series E and F is delivered at the moment at which a series of. These alternating cheese loaves face the scissors. Then a change in the mechanisms ensures that the arrangement is properly sifted parallel to the movement of the device. In addition, this direction of travel of the conveyor enables, while at the same time alternating the arrangement of the mechanisms by which the transverse strut 190 is displaced by the cam track 186 in the same parts as those described above in a forward transverse direction.

Change at the point of removal of the tape. The order trolley can be ready for waste. Open the cam tracks 227 and 228, which 45 are kept ready outside the device, since arms 23 and 24 of the gripper are connected to a power take-off point at the point where this can be removed in place of the nozzles 229 the application bath at constant temperatures. Keep the through the nozzles towards the temperature. This allows air blown with a single striker 20 of the gripper loosens the device to treat cheeses which are detached from cut tape ends which fall into the vent 5 from one another due to their shape and in particular through 231. The transport grippers then come to distinguish the quality of their coating,
The curved paths 227 and 228 close freely. The correct application of the paraffin to the freit, up to the device for loading with cheese loaves, requires that the dipping and the loaf be taken. The work cycle for wrapping them around each other with tape completely twisted and for applying the material to which speeds are applied then begins anew. which is considerably greater than the translation speed
