Description

[Meat-Bone Sawing Machine Having Safety Push Bar]

The present invention relates to a fracture machine for cutting an edible bone or frozen meat using a rotating band saw, which minimizes work to be added to an existing work procedure and fundamentally blocks exposure of a worker's hand to a dangerous area during work, To a fracture machine equipped with a safety stop which enables safe cutting operation at a minimum cost by additionally manufacturing and attaching some components without changing the design of the fracture machine itself.

Generally, a fracture machine is used to cut an edible bone or a frozen meat using a band saw rotating by the driving of a motor, and is often used in a food supplier or a butcher.

When cutting such edible bones and frozen meat using a fracture machine, there is almost no frictional force with the work table and there is almost no resistance generated when the cut pieces are cut. Therefore, various safety accidents occur frequently even in small mistakes.

In order to cut an edible bone, a frozen meat, and the like to a predetermined size using a conventional fracture machine, an operator must hold the cutting water with his / her hands in front of the band saw to pass the band saw.

However, the safety cover mounted on the conventional band saw can adjust the height for adjusting the exposure length of the band saw, but it is not a structure to be interlocked with the cutting operation. In many cases, the cover is removed from the workplace by a troublesome height adjustment operation.

On the other hand, there has been proposed a safety device capable of pushing and moving a cut material, but it is rarely used in Korea. In Europe, safety pins must be installed in the fracture period.

The reason for not using the safety pin in Korea is that it is difficult to purchase the fracture machine equipped with the safety pin, and the additional work process is required when using the safety pin and the structure is inconvenient to firmly support the cutter.

The above-mentioned conventional safety push rod has good usability in the case of dividing the cut piece.

However, according to the safety pin of the related art, when the cutter is positioned between the band saw and the safety stopper, it is difficult to fix the cutter by only the safety pin, so that the worker fixes and cuts the cutter at the cutter by hand. This often causes disasters due to the rotation of the cut material during cutting.

In recent years, automated fracture machines have been produced and used in some workplaces where a large number of identical operations are repeatedly performed.

However, the above-mentioned automatic fracture machine is very expensive compared to the manual fracture machine, and is not well utilized in a small-scale workplace that cuts various types of cuts at one fracture period.

When such a fracture machine is used, accidents involving injury to a finger or a hand of a worker frequently occur. The main causes are as follows.

In the case where the cutting water is pushed in the direction of the band saw on the table plate having relatively low frictional force in the state of holding the cutting water with both hands, both hands have no supporting point and there is no frictional force between the cut material and the table so that the movement of the cut material is free, Is very small.

Therefore, the force required to fix the cut material at the time of cutting is very small.

In such a working situation, even when only a small external force acts on the band saw during bone cutting (lack of tightening due to various parts of the frozen meat or thawed parts of the frozen meat), the operator easily loses control and a disaster occurs.

Further, when the cut material is cut while being strongly pressed, the frictional force between the table and the cut material is very small as compared with the pressing force, so that it easily slips.

For example, when the ribs are cut to a small size of about 2 to 5 cm, they can easily be contacted with the band saw easily by the imbalance of the two-handed force.

In addition, in the case of cutting ribs or the like in a cold meat or thawing process, the thawed portions are chewed on the band saw without being cut off, so that the operator's hand is sucked into the band saw to be damaged.

In the case of cuts mixed with meat and bones when pushing the cut material into the workbench, a dangerous situation may occur in which the strength of the force is not adjusted and the hands strongly enter the band saw.

On the other hand, in some cases, a safety cover is provided on the band saw, but in this case, the exposure length of the band saw can be manually adjusted, but it is not easy to use because it is not automatically interlocked.

That is, since the operation of adjusting the height of the safety cover is troublesome, the safety cover is rarely used in the actual workplace.

A conventional folding machine equipped with a safety pin has utility in case of cutting a cut piece having a predetermined shape. However, when a cut piece is positioned between the band saw and the safety pin, the cut piece is fixed It is pointed out that there is no protection function against the danger that the cutting water is caught on the band saw when it is cut or cut.
