Description

The invention relates to co-processing equipment and can be used for cutting meat or other small-sized semi-finished products at m- and fish factories, catering establishments, and also a trading network.

A device for cutting meat is known, comprising two sets of cutting mechanisms arranged in series, one of which consists of circular knives mounted on a shaft connected to the drive, and the other one comprises fixed knives attached to the body and two movable knives operating according to the principle

guillotine shears and attached along forming to the drum.

The device also contains movable flaps, a cam with rollers in its groove.

M with loaded into the bunker; fills the drum cavity when the circular blade is raised above the hopper. When the drum rotates, it cuts the knives.,. When the upper roller moves along the cam groove, the sash moves to the side surface of the drum and pushes the strip of meat under the disk knives, which cut it into pieces. Then m from comes to the outlet. When moving the lower roller along the groove of the cam, the next flap of displacement is VL O O

It goes inside the drum to form a cavity, and the process repeats.

The disadvantage of such a device is the impossibility of cutting portions of semi-finished products that are stable in mass and shape of the pieces and the need for additional portioning devices from the total mass of the cut product.

All this makes it necessary to manually select and tightly stack the pieces into the packaging form, which reduces productivity.

Also known is a machine for cutting meat into pieces, the working body of which consists of two moving knife grids with plate blades and a cut-off sickle knife. The machine has a subpressing device for stabilizing pieces of meat when it is cut off. Also known is a machine for cutting meat, consisting of a welded bed, loading hopper, pre-pressurizing device, raw material, feed chamber, shut-off knife, knife grids, cutting sickle-shaped knife, hydraulic and electromechanical actuators and controls.

The disadvantage of such a machine is low productivity.

The purpose of the invention is to increase productivity, increase the filling density of packaging forms with pieces of raw materials.

The goal is achieved by the fact that the proposed machine is equipped with an additional pre-pressing chamber located between the knife frames, its walls are made with inclined plates for cutting off the side streams of the machine, the ends of the side walls have bevels inside the chamber, the bottom of the chamber is installed with the possibility of reciprocating movement, and also a vertical piston with built-in spring-loaded plates oriented to the grooves between parallel cross-cutting blades, with a subpress under the chamber Application is with a packaging conveyor form synchronized with the operation of the vertical action of the piston, which in turn, via appropriate mechanisms matches the movement from the actuator motion and cutting of the longitudinal reciprocating movement of the bottom.

Figure 1 shows the device, a general view; FIG. 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 2.

The device consists of a bed 1, a raw material feeder 2, a raw material supply chamber 3, a longitudinal cutting actuator 4, a longitudinal cutting knife frame 5, a camera 6

pressing, the walls 7 of which are made with inclined plates 8 for cutting the meat and bevels 9, the bottom 11 of the chamber 6 is installed with the possibility of reciprocating movement with the help of the drive 12, under the bottom 11 there is a knife frame 10 of the transverse cut. Spring-loaded plates 14 are embedded in the vertical piston 13, the piston 13 is moved by the actuator 15, and the plates 14 are driven by the actuator 16. Under the chamber 6 there is a conveyor 17 with a packaging form 18, for example, made of plastic film. The movement of the conveyor 17 is synchronized with the operation of the actuator 15 of the piston 13, which through its kinematic mechanisms (not shown) coordinates its movement with the longitudinal-cutting actuator 4 and the plate 11 actuator 12. Well-known devices such as end switches can be used as synchronization devices (not shown) , cams, chain, gears in conjunction with the control logic.

The device works as follows

Boneless meat is loaded into the feeder 2 of the bed 1, it enters the raw materials supply chamber 3 and pushes the drive 4 through the longitudinal cutting knife frame 5 into the chamber 6. The bars after the knife frame 5 are supported by the bottom 11, which with some delay starts to move drive 12 along with bars m sa. At the end of the drive stroke

12, bottom 11 exposes the cross-cut knife frame 10, and the bars lay on these knives. When pushing the meat into the chamber 6, the extreme lateral substandard bars are guided by the inclined plates 8 of the wall 7 to the collection for further processing, and the conditioned, i.e. standard bars are pressed by bevels 9, i.e. podpressovyvayutsya, eliminating the gap between the bars, formed due to the thickness of the knife frame 5. Moving the actuator 4 corresponds to the length of the chamber 6. Next, under the action of the actuator 15, the piston 13 with the plates 14 recessed flush in its bottom drops down to the bars of the machine lying on the knife frame 10 transverse cutting, after which the piston

13 is stopped, and the plates 11, oriented into the grooves between the knives of the knife frame 10, are lowered between them, pushing and simultaneously cutting across the bars of the machine into pieces of a certain length, which fill the corresponding chamber 6 and the packaging form 18 below it. After that, the plates 14 are driven by the actuator 16 and the piston 13 by the actuator 15 to the initial position, at the same time the bottom 11 by the actuator 12 and the actuator 4 are also returned to the initial position, and the conveyor 17 brings the next packaging form 18 under the chamber 6, after which the cycle repeats.

A filled som packaging form 18 is fed to a seal, for example, to a vacuum packing machine. If it is necessary to change the sizes of the pieces of meat, only blocks of knives and plates are replaced.

Thus, using the invention allows to increase productivity, eliminating the operations of collecting pieces of meat into dosing bins and their orientation in the packaging form, increasing the density of filling and automating the filling of the packaging form, which makes it possible to fit the device into the packaging line and eliminate manual labor.
