Description

The subject of the invention is a machine for cleaning (deflashing) bones for butcher shops, Slaughterhouses and other commercial businesses. The machine is for the machine Processing of all bones, e.g. B. rib bones, tubular bones, spinal bones and the like. Provided.

The butcher industry has numerous machine facilities that enable savings and To facilitate manual labor, so that only relatively few and subordinate Work must be done by hand. So far, however, it has been felt that the Any loose bones occurring in the butcher's shop cleaned with the help of manual labor, d. H. must be freed of meat residues. The work of cleaning bones is time consuming and takes up a considerable part of the working time, and moreover, relatively well trained Skilled workers are required. The shortage of skilled workers in this branch of industry often has the consequence that this work at all can not be carried out and the bones with adhering meat residues therefore for subordinate Purposes must be used or even discarded.

There are already mechanically operating devices for cleaning bones known, but provide these are usually tools that can only be carried out by hand. B. a mechanically driven, hand-guided cutting knife for cleaning the bones has been proposed as a helical wound steel strip is formed with sharp cutting edges. Another familiar one Tool consists of a ring-shaped knife that can be rotated around the center axis of the ring, the also has to be carried out by hand. Furthermore, a tool with a shape similar to a spiral drill has become known, which is not arranged in a fixed position either, but is carried out freehand. Even no holding devices for the bones are provided in the known device, so that apparently the hand position of both parts is also provided freehand according to this proposal.

Another type of known device has a scraper head which is arranged in a stationary manner on a machine on, with the bones mounted by hand or on a corresponding holding device, brought to him Need to become.

Furthermore, a mechanical device for cleaning bones has become known in which the over a conveyor belt brought bones are passed between jet nozzles, the under Bone cleaning machine

Water leaking under higher pressure is supposed to remove the meat from the bones. But this machine is apparently only suitable for removing meat that has already largely decayed and Incidentally, it also differs fundamentally from the subject matter of the invention in its mode of operation. Another device that has become known consists only of a support bridge for bone cleaning machines, which is designed as a rotating roller and serves to support the bones.

The invention is based on the object of creating a mechanical device which allows the work of cleaning bones, partly by machine, with less personnel, and with the help of unskilled personnel. According to the invention, the machine is for Cleaning (removing flesh) of bones from a mechanically driven, roller-guided, endless self-contained band knife and a known rotating, mechanically driven Twist drill-like, one-sided clamped drilling and cutting tool with several over the circumference distributed cutting edges running along the shaft, which are in a common machine frame are fixed, as well as one or more, in slide guides along the drilling and Cutting tool or in the direction of rotation of the band knife movable, rotatable, with handles and a hand guard arranged between the handles and the holding device Support or support brackets for the bones to be worked on.

Compared to the known devices, the combination of the roles guided in closed band knife with the spiral drill-like rotating drilling and cutting

tools that may be mechanically driven by a common drive, and with the support or holder brackets according to the invention for the bones a versatile use for the intended purpose. Due to the bone support, it is also inexperienced personnel possible to operate the machine safely, as the hands are protected by the plate. Is exposed only the drilling and cutting tool and the small one from a section of the possibly to be provided Fairing excellent part of the band knife. On the other hand, it is in case of need possible, particularly complicated bones also by hand with the help of the support device to be completely freed from leftover meat. The band knife is essentially used to cut bones with smooth To free areas such as rib bones and tubular bones, shoulder blades and the like from leftover meat while Hip bones and spine as well as skull bones with the rotating drilling and cutting tool can be edited. The support or holder brackets that are moved in the working direction can serve to hold the bones. The machine can do a lot of the work that would otherwise be required human actions are replaced by mechanical work. In addition to saving time the otherwise occurring symptoms of fatigue are also excluded. Since the one to be performed Work can be carried out professionally and cleanly by unskilled personnel after a short training period the machine frees up numerous skilled workers for other purposes.
