SE469814B - Method and apparatus for automatic loading of animal bodies in cold storage - Google Patents

Description

469 814 that it takes a long time to load a cooling space.

An additional problem is that you usually have a person who makes sure that the meat comes out of the slaughterhouse's cold room while a person stands and loads the meat and takes care of switching between the tracks manually and that another person stands inside the mobile cold room and packs the meat towards the front of the space and where even to pack efficiently today you have to drive the whole phone down a hill and then brake so that the meat with the force of movement will move forward and where you also have a person at the back who when the phone is braked unlocks the meat by stopper . The risk of an accident is therefore very great. The problem is that you want to load as much as possible in the mobile cold storage so that the transport can be economically defensible.

Another problem is the hygienic requirements that are placed today on these transports. Having people walking inside the cold room with shoes that you use outside and that when you pack the meat you directly touch the meat is something that everyone wants to get away from to get better hygiene.

In addition, it is a big problem to load the space, as when loading large livestock you have to pack the meat in a special way to make room for as much as possible. You must pack the front part and the back part alternately in two rows so that the meat is evenly distributed during loading.

The problem with getting a good economy in these transports is that there are too many people involved in loading and unloading and that it takes far too long in connection with this. 4o9 814 Furthermore, it is the case that work personnel often suffer injuries, direct or indirect wear and tear injuries.

An object of the invention is to create a method and facility for a worker to handle and unload meat to and from a mobile cold room, without risk of accidents and occupational injuries.

Another object of the present invention is to be able to handle meat and the space where the meat is to be stored in a more hygienic manner and that the handling takes place automatically without working persons coming into contact with the meat or the space where it is stored.

Yet another object is to significantly reduce costs and tasks by means of an automatic loading and unloading system where a high loading speed is obtained, an efficient packing of the meat and unloading of the load by only one person.

Another further object of the invention is to reduce emissions of cold from the cold room by being able to quickly load, pack and unload the meat in the mobile cold room.

Thus, according to the present invention, there is provided a method for loading, packing and unloading animal carcasses, meat or the like, whereby the working environment, hygiene and economy will be considerably improved.

The invention also relates to a plant for carrying out the above-mentioned method. The facility includes loading and unloading pipes to a mobile cooling room as well as a number of gear joints which lead the meat into various track pipes and where packers move forward and pack the load to backstops that hold the load in place and that an electronic system can determine opening and closing the gear joints to be able to guide the hanging meat on different web tubes and enable efficient packing.

Another automatic system that releases the backstops and stops when unloading the meat.

The characteristics of the present invention appear from the following claims.

The invention is described in more detail below by means of a preferred embodiment of the invention with reference to the accompanying drawings. In this case, Figure 1 is a preferred embodiment of the plant seen from below and Figure 2 shows a mobile cooling space from behind and Figure 3 is a side view of a mobile cooling space with the plant mounted inside. Figure 4 shows a gear joint with its various details connected to a track tube and Figure 5 shows the same gear joint connected to the loading tube and Figure 6 shows the gear arm from the front while Figure 7 is a view of section AA of the gear arm and Figure 8 a view of section B - B of a track tube.

Figure 1 shows from below a part of the plant in a mobile cooling room. You can see the different web tubes 1 where the number of these depends on the size of the cooling space and how these web tubes 1 are fixed by means of holders 2. Along the web tubes 1 LÉ-69 814 there are stops 3 for the roller hooks or sliding hooks which transport the animal carcasses and / or meat. . When the mobile cold room is to be loaded from a slaughterhouse, a track pipe will be connected to the loading and unloading pipe 8 and the meat will be transported to the mobile cold room and into this pipe 8, a pneumatic cylinder 4 being regulated from the driver's control box outside the mobile cooling space to make a gear arm 7 rest against a track tube 1, whereby the hook with the animal enters the track tube 1. In the figure you can also see a number of gear joints 5 and different gear stops 6. When it comes to loading large livestock with alternating front and rear part for two track tubes 1 can be set via the control box so that the two cylinders 4 work alternately with the gear arms 7 and one can thus load front part, rear part and front part etc on one track tube 1 while the other track tube 1 has rear part, front part , rear part, etc. In this way, there will be no dead cargo space at the same time as a man outside the mobile cooling space controls the whole thing.

Figure 2 shows a mobile cooling space from behind and you can see the ends of the loading and unloading pipes 8 which are intended to be connected to the slaughterhouse's unloading pipes from their cooling space.

Furthermore, one can see a manual positioner 9 which can also be used to regulate the shift in the space.

Figure 3 shows a mobile cooling space from the side and you see the track tube 1 on which an animal body hangs on a hook which hangs on the track tube 1. The automatic loading of the meat in the mobile cooling space takes place by means of a packer ll which is set at a certain pressure. This presses on the upper part of the hook 469 814 6 and moves the hanging animal body into the mobile cooling space towards the front and under the packer 11 there is a line of backstops 12 and when the packer moves the hook 10 at the front and when the preset pressure is reached the hook 10 to be held by a backstop 12 and the packer 11 returns to the initial position to retrieve a new hook 10. When unloading all animal carcasses hanging in the cold room, all backstops 12 will be turned up and the animal bodies are held back by the stops 3 which are regulated by the driver. control drawer and releases the hooks 10 after control signal and unloading can take place in an orderly manner either whole track tubes at a time or one hook from each track tube at a time. Loading and unloading can of course also be done manually with the help of the positioner 9.

Figure 4 shows the actual switching between the web tube 1 and the loading and unloading tube 8 and it is seen how the pneumatic cylinder 4 which is attached to the gear arm 7 has caused the gear arm 7 to abut against the web tube 1. In the exemplary embodiment we have said that the cylinder 4 is pneumatically controlled. but this can of course be controlled in different ways, for example through electronics. You can also see the gear stop 6 on the tube 8.

Figure 5 thus shows how the pneumatic cylinder 4 has retracted the gear arm 7 to abut against the loading and unloading pipe 8 instead. You can also see the gear stop 6 on the track tube 1.

Figure 6 shows the end edge of a gear lever 7 and you see the guide pin 13 for the gear arm.

Figure 7 shows a cross section AA of Fig. 5 and the guide pin 13 is seen in its guide groove 14 when the gear arm 7 rests against a pipe 1 or 8. n 7 469 814 Finally, Fig. 8 is a sectional view BB of a part of fig. 5 and one sees there the gear stop 6 in the track tube 1 and the guide groove 14 in which the guide pin 13 is intended to enter.

The drawings have shown only one embodiment of the invention, but it should be pointed out that it can be designed in many different ways within the scope of the appended claims.
