Description

Title of the invention

Method and device for the mechanical loading of shelves, in particular smoking wagons

Field of application of the invention

The invention relates to a method and an apparatus which mechanizes the loading process of smoke trucks with sausage and meat products threaded on bars. '

The inventive method and the associated device can be used with particularly good effect in fish processing plants.

Characteristic of the known technical solutions

There are no mechanical methods and devices for loading smoke trolleys with bars (smoke pots)

known. ,

The loading is done manually by the rods of a worker in the receiving profiles of the smoke truck floor by floor

be hung. '

This activity is usually carried out by female workers in meat processing plants and represents a significant physical burden, as the weight of the occupied bars is about 12kg.

According to legislation (ASAO 5), the lifting of permanent loads for female workers is limited. It follows that the incense sticks could not be fully occupied and thus a full occupancy of the smoke truck is not given.

Due to the only about 70% occupancy of the smoke trolleys, an equivalent capacity restriction is caused in the air-conditioning chambers and the ripening rooms, which leads to a reduction of the throughput in these areas and to increase

the specific energy cost per tonne of finished product. '

Object of the invention

It is an object of the invention to provide a method and an apparatus for the mechanical loading of smoke wagon, which eliminates heavy physical labor compared to the previously used manual procedure and ensures optimum occupancy of smoke wagons.

With the full occupancy of the smoke trolleys, climate smoke and ripening facilities are fully utilized, the production throughput increases, which ultimately results in a reduction in the specific energy costs per t finished product. At the same time a worker is released, so that compared to the conventional procedure, a high efficiency is achieved.

Explanation of the essence of the invention

With the application of the proposed method and the associated device eliminates the manual loading. The invention results in the mechanization of the auxiliary production process "loading of the smoking wagon" and is divided into three process steps:

- Feeding the rods to the receiving arms

- Transport of the rods in the smoke truck

- Floor-wise occupancy of the ventilation profile of the smoking wagon ' _:

This object is achieved in that a worker inserts without lifting the stocked with sausage or meat rod in a Beladeelevator.

The loading elevator transports the bar to the fixed position of the receiving arms of a loading unit. The loading is continuous. .- '

By a stroke-push unit in the receiving arms of the further transport of the rod is carried to the final position in the corresponding floor of the smoke truck.

After positioning of a floor within the smoke truck, the automatic lowering of the receiving arms for storage of the rod takes place in the receiving profiles of the smoke truck.

The lowering of the receiving arms erfqlgt until the next looming loading days in the smoke truck or the lower end position is reached.

This completes the automatic loading process.

Due to the structural design of the loading elevator and the Au'fnahmearme and the transfer points between Beladeelevator and receiving arms and the Steuerungsungsseitigsn concatenation of both units a continuous loading process is secured, which is not interrupted in the transition from one smoke car floor to the other.

By modifying the control, the process can be continued even if the smoke truck is occupied and by an empty smoke warehouse. is exchanged, in this period, a smoke truck floor can be pre-stacked on the receiving arms of the feed unit, so that even when replacing the smoke truck loading process must not be interrupted.

Depending on the technological requirements for different assortments, the method according to the invention and the associated device enables a variable loading of the smoking wagon within a floor as well as in the floors themselves. The mechanization of the loading process for smoke wagons has become an important prerequisite for the automation and increased performance of the sausage and meat products manufacturing created.

embodiment

To further illustrate the invention serves as an embodiment, the loading of a smoke truck with raw sausage including attached three drawings.

Carcases are mobile shelves (4), in which raw sausage products hanging on rods (5), transported, and go through the individual process stages to the point of shipment. Different Röhrwursterzeugnisse be in different

Beladeordnurigen in the smoke trolleys (4) hung. Λ

The device for loading the smoke trucks (4) consists of the following modules:

- Beladeelevatör (1) ',

- Feeding unit (2)> -

- Lifting unit (3) 'The filled and sealed raw sausages are threaded onto bars (5) (smoke sticks) on a loop clipped into the closure. Since the manual loading of the smoke truck (4) is mechanized by the device, the rod (5) can be occupied to the maximum. After threading the sausages on the rod (5), the same is inserted without lifting in the receptacles (6) of the loading elevator (1). The Beladeelevator (1) is equipped with two circulating transport chains (7), which are provided with receiving means (6) for the rods (5). The free ends of the rods (5) are inserted into the receptacles (6) of both transport chains (7) located in a horizontal plane. The transport of the rods (5) takes place through the loading elevator (1) after the deflection from the rising to the falling direction of movement until reaching the loading unit (2). Characterized in that the receiving arms (8) of the loading unit (2) between the transport chains (7), the rod (5) in the falling movement of the Beladeelevators (1) independently from the receiving arms (8) of the loading unit (2). In the receiving arms (8) of the loading unit (2) transport rails (9) (10) are mounted, which transport by a coordinated stroke-pushing movement of the Beladeelevator (1) rod (5) on the profiled receiving arms (8).

In this way, the deflection of the direction of movement of the rods (5) from the vertical plane in Beladeelevator (1) in the horizontal plane in the feed unit (2). The transport rails (9) (10) of the receiving arms (8) run synchronously, each transport rail (9) (10) has a separate drive, both the lifting and pushing movement are generated by pneumatic cylinder (17) (18). (Detail Z, View Y) By control side linkage of these cylinders (17) (18), the parallel Tränsport the rods (5) on the receiving arms on (8) of the feed unit (2) is performed. Depending on the loading program of the smoke truck (4) the exact positioning of the rods (5) on the receiving arms (8) of Bescnickuhgseinheit (2) on the in the same way as the rods (5) are placed in the smoke truck (4) , If the loading unit (2) is fully occupied with the number of bars for a smoke truck level, the lifting unit (3) lowers the loading unit (2). When lowering the loading unit (2), the rods (5) are stored in the receptacles (15) of the smoking carriage (4). The lifting unit (3) brings the loading unit (2) in the loading position for the next lower lying loading level of the smoking carriage (4). This sequence is repeated until all levels of the smoke truck (4) are loaded. After removal of the loaded smoking carriage (4) moves the lifting unit (3) in the upper loading level, the loading unit (2) starts again with the acquisition of the rods (5) to the number of rods (5) for a loading plane on the receiving arms (8 ) is upstream. If no additional smoke trolley (4) is inserted into the lock (16) by this time, the loading process is interrupted. After insertion of an empty smoking carriage (4) in the lock (16), the entire loading process, as described above, automatically re-runs, starting with the lowering of the fully occupied loading unit (2) for the upper loading level of the smoke truck (4). *.

With the application of the proposed method and the associated device, the following advantages arise: r-saving a worker, since the manual loading of the smoke truck is eliminated

- Improvement of health, work and fire protection, as well as working and living conditions

rr increasing the capacitive load of the smoke trolley, and the Räucheranlägen and ripening rooms connected to the

Reduction of specific energy consumption per ton of finished product - extended applicability when loading shelves where the load is to be conveyed and stored suspended in one or more defined planes in one or more positions in the horizontal plane.
