Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus that is equipped with a cutting mechanism that automatically cuts meat such as animal meat into an appropriate shape, and that automatically skewers cut loe pieces.

Conventional meat skewering devices feed pieces of meat cut into cubes into appropriate shapes to a skewering machine and automatically skewer them.
Animal meat, such as bone-jointed meat (referred to as thigh meat) of chicken, is diced into rectangular shapes by hand or using a meat cutter, and then the skewers are lined up and fed into the supply conveyor of the skewer machine to be skewered. This process requires a lot of time and effort, and has drawbacks such as the shape of the skewered pieces of meat being distorted and irregular, resulting in poor appearance, and low production efficiency.

This invention solves the above-mentioned drawbacks.

Then, the meat a is cut vertically by the rotary knife 36□ attached to the extended rotation @34 of the motor shaft (see Fig. 7).

And usually as shown in Fig. 6 and Fig. 8 A.

The moving plate 28 is raised upward, and the vertical cutting brackets 311, 312 fixed to the moving plate 28 and the vertical meat cutting mechanism and perforating metal fittings 37 for moving the motors attached to the brackets 31□, 31° are shown. A meat suppressing mechanism consisting of a presser plate 43 is located above the transfer conveyor 1 with a gap equal to the thickness of a piece of meat.

In this case, the inner holding plate 43 is pushed down below the perforation fitting 37 by the elasticity of the compression spring 44 (see Fig. 8), and the needle 39 on the underside of the perforation fitting is inserted into the needle hole 4 of the meat piece holding plate 43.
It's pulling into 7.

Then, the meat a placed on the transfer conveyor 1 is brought below the vertical cutting mechanism and stopped. At this moment, the air cylinder C-2 is activated and the moving plate 28 interlocked with this is moved vertically. It descends together with the cutting brackets 311 and 312.

At the same time, the vertical cutting bracket 31□. The perforating metal fitting 37 attached below the perforating metal fitting 312 also descends, and when the meat holding plate 43, which is suspended from the perforating metal fitting 37 and facing the piece of meat, is pushed upward by the resistance of the meat piece, a large number of needles on the lower surface of the perforating metal fitting 312 are lowered. 39 protrudes from the needle hole 47 as shown in the mouth of FIG. 8 and FIG. The upper surface of the meat a is pressed so that the edges of the meat a do not curl up or bulge due to elasticity, and are firmly pressed onto the transfer conveyor 1.

This state of holding down the piece of meat is continued until the vertical cutting process of the meat is completed.

When the meat presser is attached, the motor m1 is started at the beginning of the process, and the knife cuts into the meat while rotating.

Next, when the meat pressing process is completed, the motor m1 movably suspended from the parallel guide shafts 32□, 32□
is moved forward by the piston rod 50 of the air cylinder C-3, and the rotating knife 361°3 attached to the motor shaft is moved forward by the piston rod 50 of the air cylinder C-3.

It should be noted that the cutting board plate 11 of the transfer conveyor is shown in Fig. 9.
As shown in FIG. 10, a knife groove 1b may be carved.

Next, the transfer conveyor 1 carrying the vertically cut meat pieces a' moves forward and brings them to the transverse cutting mechanism C.

This cross-cutting mechanism C is a mechanism for slicing the piece of meat a' vertically cut in the previous step into cubes of appropriate width.
In this cross-cutting mechanism, there are two rotary knives that move in a direction perpendicular to the direction of movement of the transfer conveyor 1 (see the left side of FIGS. 6 and 7).

The embodiments of this cross-cutting mechanism shown in FIGS. 6 and 13 will now be described.

The horizontal cutting mechanism is the moving intermediate plate 2 of the vertical cutting mechanism B.
8 is common, and a cross-cutting bracket 3 is installed on the lower surface of the moving plate 28 that moves downward by the same air cylinder C-2.
11' and 312' are hung vertically facing each other with the transfer conveyor 1 in between, and the cross-crossing brackets 31□' and 312 are
'A guide map 32 parallel to the transfer conveyor 1 at right angles to the upper part of the conveyor 1.

The meat piece suppressing mechanism is elastically suspended by a spring 44' through four rods 42', and when the transfer conveyor 1 stops moving, it descends with the lowering of the moving plate 28, and perforates a large number of perforations on the lower surface of the perforation fitting. Since the needle 39' is used to pierce the piece of meat a' and the plate 43' pressed by the compression spring 44' is used to press the piece of meat a', the piece of meat a' that has been cut vertically is
An appropriate number (two in the drawing) of rotating knives 361' move the knife horizontally between the needle rows by operating the piston rod 50 of the air cylinder C-4 while holding the knife tightly and securely on the transfer conveyor 1; 362', it is possible to cut the material into a uniform shape with a sharp cut edge (FIG. 10A).

As shown in the opening of Figure 10, when cutting with only the holding plate pressed, the cut side sticks to the knife and the knife passes over the sharp point again, resulting in hangs (split into thin pieces) and pieces of cut meat. Its elasticity prevents it from becoming distorted.

In the embodiments of the present invention described below in the main text, the circular rotary knives 36r, 36 with the above-mentioned horizontal cutting mechanism are used.
Before □' starts to move across, that is, at the time when the transfer conveyor 1 presses down the piece of meat a' with the numerous needles 39' of the perforation metal 37-year surface and the holding plate 43', the skewering mechanism described later is activated. Chiruga is a piece of meat that has been cut lengthwise, skewered, and then cut crosswise.

It goes without saying that the vertically cut meat piece a' may be laterally cut and then skewered as it is, that is, the cubed meat piece a' is held down by the perforating needle 39' and the holding plate 43' using the skewering mechanism described later.

This skewering mechanism D (1° Fig. 3 and Fig. 13 to 1
As shown in FIG. 9, it consists of a skewering mechanism d1 and a skewering mechanism d2, which are provided on a table 52 provided horizontally in a perpendicular direction to the machine frame body 2 in the section of the cross-cutting mechanism.

With the notches provided on the □ and 572 sides, one or two skewers outside the first row are arranged horizontally facing the small descending grooves 57□ and 572. W is a disk 58 attached to the motor m3 shaft, which is formed so that the skewers do not interfere with the descent when the sun sets 56'.
It is a swinging member that applies pressure and oscillation to the oval which is vertically suspended from an eccentric pin 59 by a string 60, and has skewer pressing shoulders 61□, 612 in a stepped manner on the upper part, and shoulders 61□,

It is loosely inserted into fixing pins 63□ and 63° so as to hold 57□ and guide the vertical movement of the swinging portion 1OW.

64□, 642 are the swinging members W in the hopper 53.
The skewer fixed parallel to is a member, and the skewer with a triangular cross section has a head 65 and side surfaces 66 □ on both sides below it.
, 66□ coincide with the lower side surface portions 62□, 622 of the swinging member W, and there is a small descending groove 57 between the inner members 541 and 542 of the small beam.
□, form 572.

Hold both sides of the skewers S lined up horizontally and vertically in the small descending grooves 57□, 572, and reliably feed the skewers S into the two small grooves 55□, 552 provided on the table 52, one on each side on the left and right. (See Figure 17 and Figure 18 A).

And 67□, 67° (''The internal member of the small beam 54°.

A slit is formed between the sliding grooves 67□, 672 and the upper surface of the table 52 by the sliding grooves of the skewer holding plates 680, 682 provided on the lower surface of the skewer holding plate 542, and the sharpened skewer holding plates 688, 682 are attached to the table 52. A small groove of 55° is inserted between the skewers in close contact with the surface.
Hold down the top surface of the skewer S that is descending one by one on the left and right at 552,
The skewer is completely accommodated and held in the small groove, maintained in a position where the skewer can be reliably pushed out by a push rod (to be described later), and returned to its original position after the push rod moves back.

Note that C-5 and C-6 are air cylinders that reciprocate the skewer holding plates 68□ and 682, and are branched from, for example, the same compressed air pipe (not shown) so that they operate simultaneously when the plates are lowered during movement. It is operated by a compressed air pipe.

Next, in FIGS. 13 and 14 showing a mechanism for pushing the skewer S and skewering the vertically cut pieces of meat on the feeding conveyor, 690 and 692 are the small grooves 55 □ provided on the table 52; A push rod is inserted into the push rod 552 so that it can move forward and backward; 70 is the rear end of the push rod 690, 692 (the left end in the figure)
The push metal fitting 70 is attached to the table 52.
It is attached so as to interlock with the piston rod 71 of the air cylinder C-7 provided above in parallel with the push rods 691-692, and slides freely forward and backward along a small groove on the table 52.

72 is a guide roller of the pusher 70, 73 is the pusher 7
This is the limit switch operating rod (Fig. 3) attached to 0.

Next, to explain the interlocking mechanism that interlocks each of the above-mentioned mechanisms, in FIGS. 1, 2, and 3, Va is the solenoid valve of the air cylinder C-1 that moves the feeding conveyor 1, and vb is the meat piece suppressor. Solenoid valves of air cylinder C-2 and skewer holding plate actuating air cylinders C-5 and C-6, Vc is the solenoid valve of air cylinders C-3 and C-4 for vertically cutting meat pieces and moving knives across the sides, Vd is skewering air The solenoid valve of cylinder C-7, 11 and 42 is a limit switch that detects the left and right dead center of the air cylinder C-1 piston and switches the forward movement of the tech stone to backward movement, j3 and 1.
4 is a limit switch for switching the air cylinder C-2 piston down and up, 15, 16 and 17 are limit switches for switching the forward and backward movement of the air cylinder C-3 and C-4 pistons, 18 and 19 are air cylinder C -7 Limit switch for piston forward and backward movement switching, rl, r21i limit switcher 11/12 control fitting, r3 is limit switch 13/14 control fitting, r4 is limit switch 17 control fitting. .

Note that 74 is a pressure regulating valve, 75 is an oiler, and 76 is an air filter.

Then, when the switch is turned on, the interlocking mechanism opens the solenoid valve Va and sends compressed air to the transfer conveyor driving air cylinder C-1, which is activated to move the transfer conveyor a certain distance and the piston rod's control fitting r2 force 5 limit switch 12 When the air cylinder C-1 is activated,
This is to switch the forward movement of the piston to the backward movement, but a timer (not shown) separately provided in the electric control box E is activated to stop the transfer conveyor for a certain period of time, and during that time a relay (not shown) is activated. The solenoid valve vb, which moves the piston of the meat suppressing air cylinder C-2 downward, is operated through the solenoid valve vb.

Next, actuate the solenoid valve Vd that moves the skewering air cylinder C-7 piston forward to skewer the skewer, and then the relay (
(not shown), the vertical cutting knife motor m1 and the horizontal cutting knife motor m2 are rotated, and the solenoid valve Vc is actuated to cut pieces of meat vertically and horizontally using the vertical cutting air cylinder C-3 piston and the horizontal cutting air cylinder C-4 piston. After the cutting, the timer times up and the air cylinder C-1 piston starts to move backward while stopping the transfer conveyor 1 due to the idle movement of the ratchet wheel 9.At the same time, the limit switch 13 switches the solenoid valve vb to stop the air cylinder C-1. The two pistons are moved back and the moving plate 28 is pulled up, then vertically cut, and the transverse cutting motors 11"Its n12 are returned to their original positions.

During the work, the motors m12m2 for the knives and the motor m3 that swings the swinging member in the hopper continue to rotate, and the operating rod 73 that controls the operation of the skewering air cylinder C-7 continues to rotate. When the antibacterial fitting r4 acts on the limit switch 19, the air cylinder C
-7 piston is switched to double action.

When the cut-out fitting r1 of the piston rod of the transfer conveyor 1 drive cylinder C-1 comes into contact with the limit switch 11, if each of the interlocking mechanisms described above has returned to its original operating position, that is, 13, g6, and 18 are closed. , the limit switch 41 circuit is closed, the solenoid valve Va is opened, the air cylinder C-1 is operated, and the transfer conveyor is electrically connected to move the dust, and the above-described operation is repeated thereafter. .

In addition, regarding the interlocking mechanism for skewering the piece of meat a'' cut into cubes by the vertical cutting mechanism and the horizontal cutting mechanism by the skewering mechanism, the solenoid valve vb that moves the piston of the meat restraining air cylinder C-2 downward is operated. Then, the vertical cutting knife motor m1 and the horizontal cutting knife motor m2 are rotated via a relay (not shown), and the pieces of meat are cut vertically and horizontally using the vertical cutting air cylinder C-3 piston and the horizontal cutting air cylinder C-4 piston. Skewering cylinder C-7
The interlocking mechanism is the same as the above-mentioned interlocking mechanism except that the solenoid valve Vd that moves the piston forward is operated to interlock the piston in a skewering manner.

This is because the present invention is constructed as described above.

According to this invention, for example, the meat a that has been separated from the bone, such as bone-jointed meat (referred to as thigh meat) of a chicken, or breast meat of one chicken wing (referred to the meat from both sides of the spine to the breast), is moved intermittently. If placed near the entrance side 24 to the upper meat cutting mechanism of the transport conveyor 1 for feeding, the upper rotating roller 23 interlocked with this when the conveyor 1 moves forward presses the meat a on the transport conveyor while rotating. The meat pieces are leveled to a uniform thickness, and then the perforated metal piece 37, which is attached to a vertical cutting bracket suspended from the moving plate 28 that descends when the transfer conveyor stops, is attached to the lower surface of the perforating metal fitting 37, which descends together with the moving plate 28. It has a large number of perforating needles 39 implanted in the machine and a through hole 47 for the perforating needles 39, and is elastically suspended from the perforating metal fitting 37 by a spring 44, and prevents the limp piece of meat from being deformed or rolled up by the holding plate 43. The needles are securely fixed on the feeding conveyor 1, and the rotating knives 36□, 362, .

In addition, similarly to the vertical cutting mechanism, a piece of meat a cut vertically using a large number of perforating needles 39' on the perforating metal 37-year side and a presser plate 43'.
′ is pressed down, the skewer hopper 5 on the table 52 connected to the cross-cutting mechanism and attached at right angles to the machine frame body
3, the skewers S are taken out one by one on the left and right by the pressing force of the member W that swings downward and the action of shaking the skewers, and the small grooves 550 are removed.
, 552, and the left and right parts 1 further descending into the groove.
A skewer holding plate 68 that connects the upper surface of each skewer S and S to the air cylinders C-5 and C-6. , 682 and completely accommodated in the skewering groove, the push rod 6 is inserted into the small grooves 550, 552 so as to be freely forward and backward in conjunction with the skewering air cylinder C-7.
Rotary knives 361' and 36 that are pushed forward by L-69□, skewer the vertically cut pieces of meat a' on the transfer conveyor 1, and move the remaining pieces of meat laterally! 14 and 15A, or cut vertically and horizontally into cubes a'', while fixing it in the state in which it was cut with the perforating needle 39' and the presser plate 43'. Since the skewering is carried out using a skewering mechanism, it is possible to simply and easily produce an excellent product a1 (Fig. 15) in which pieces of meat a" cut into rectangular shapes or the like are accurately skewered. It is something.

In the present invention, in the above-mentioned skewering portion d1, the small descending groove 5 on the upper surface of the hanging guide members 541, 542
7□, facing the 572 side, the skewers outside the row are lined up horizontally to prevent the skewers from touching each other when the sun sets, so that the skewers are always lined up horizontally in a vertical line, and the small groove 55 provided on the table ．． , 55□ is completely accommodated and held in the skewer groove by the skewer holding plates 68□, 68□ that slide along the table surface, and the rear end of the skewer is held by the push rods 69□, 692. By firmly contacting the tip, even a somewhat distorted skewer made of bamboo or the like can be reliably pushed forward.

When arranging the pieces of meat on the transfer conveyor 1, stick-shaped green onions are inserted alternately into the vertical seams of the meat pieces, thereby producing skewered products with green onions sandwiched between the pieces of meat. You can also obtain skewers for vegetables such as sausages and root vegetables by cutting them horizontally.

It can be used for many purposes.

The following explanation based on the drawings merely relates to one embodiment of the present invention, and by suspending or removing the skewering mechanism, it is possible to mass produce cubed meat such as pork and salmon, as well as vegetables that are difficult to cut. Any other modification or modification that does not depart from the spirit of the invention, such as vertical cutting, cross-cutting, or cube cutting of other food products, feeds, etc., may be contemplated.
