Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for further cutting and separating a wing separated from a breast by demolition processing of a poultry bird, generally a chicken.
[0002]
[Prior art]
Wings cut off from the chest by dismantling processing of poultry are widely used as food ingredients, and these are further cut and separated into two parts, called “wings” and “wings”. This is well known.
[0003]
Here, the wing consists of three parts: the wing closest to the chest, the wing following the tip, and the wing tip following the tip, and the wing and the wing are cut at the joint between them. Since it is customary to provide a general consumer with a portion where the wings and wings that are obtained by separation are connected to each other, they are referred to as “wings”. Of these, the wing base is referred to as the wing base side, and the part where the wing wing and the wing tip remain connected is referred to as the wing tip side.
[0004]
The cutting and separation of the wing base side and the wing tip side is performed by a manual operation in which an operator puts the wings one by one on a cutting board and applies a knife to the joint part between the wing base and the wings. It has been broken.
[0005]
[Problems to be solved by the invention]
The work of cutting and separating by hand requires a certain level of skill to properly apply the knife to the joint part, applying considerable force to the knife for cutting, so processing a large number of wings will cause significant fatigue, so However, it has been unavoidable that the processing efficiency is low because a large number of workers are added to the system.
[0006]
Japanese Patent Publication No. 7-48976 discloses an apparatus for cutting and separating wings connected to the chest in order of wing tips, wings, and wings as means for performing wing cutting and separation without manual work. . However, this one cuts the wings into three parts in order from the tip side and finally separates them from the chest, and cuts and separates the wings separated from the chest into two to make it a form familiar to Japanese consumers It is not a thing.
[0007]
The present invention was made against the background of such a situation, and can be appropriately separated at the joint portion between the wing base and the wing side on the wing base side and the wing tip side. An object of the present invention is to provide a wing cutting / separating device which is not required and can provide high processing efficiency.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention includes a transport machine including an endless belt that is fed in one direction across a wing; and a cutting tool that extends from the end of the endless belt in the extending direction; And a transfer machine including a spiral grooved roller that is arranged on both sides of the cutting tool and meshes with the wing base side and the wing tip side that are distributed on both sides of the endless belt and forcibly transports them in the extending direction. While being forcibly transported by the machine, the straddle was cut by the cutting tool.
[0009]
According to such a cutting / separating apparatus, the operator's manual work only distributes the wing between the wing base side and the wing tip side and straddles the endless belt, so that little skill and labor are required. In addition, since it is cut while being forcibly transferred by the transfer machine in a state where the cutting tool extended in the extending direction of the endless belt is straddled, it can be appropriately cut off at the joint between the wing base and the wing. Is.
[0010]
When the endless belt in the device is a chain and has projections at appropriate intervals to prevent the movement of the wings, the wings can be smoothly fed into the transfer machine, and the joint location can be accurately Can be matched.
[0011]
Further, when the cutting tool in the apparatus is inclined so as to gradually become higher from the end portion of the endless belt in the direction of its extension, and has an upward cutting edge whose end is higher than the roller, The cutting progresses little by little with the forced transfer and can be cut without impact and with low resistance.
[0012]
And what has the above-mentioned upward cutting edge is the first cutting tool, and the second cutting tool has a downward cutting edge that is arranged so as to face the upward cutting edge at a position higher than the roller and the facing distance gradually decreases in the extending direction. When is added, reliable cutting can be performed with a short transfer distance.
[0013]
Further, when one of the rollers in the apparatus is arranged so as to become gradually higher than the other roller in the extending direction, the biting of the wings on the cutting tool is reduced, and cutting is further performed with low resistance. Can do.
[0014]
Furthermore, when the distance and height difference between the two rollers in the apparatus are variable, the wings of different sizes and shapes can be reliably meshed and forcibly transferred and cut.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described with reference to the drawings. The conveyor 1 has an endless belt 2 made of a chain arranged on a vertical plane and engaged with a chain wheel 5 driven by a prime mover 4. A portion that is in contact with the outer peripheral edge of the installed flat guide member 6 and that travels in one direction in contact with the upper edge of the guide member 6 extending in the horizontal direction is a feed stroke section 2 a of the endless belt 2.
[0016]
Further, the endless belt 2 has projections 3 protruding upward in the feeding stroke section 2a at regular intervals.
[0017]
The wings separated from the chest by the dismantling process of the poultry are placed on the endless belt 2 running in the feed stroke section 2a by the operator's manual work. As shown in FIG. 5, the wing F is in a state where the joints between the parts of the wing base F ₁ , the middle wing F ₂ , and the wing tip F ₃ are bent. Thus, the wing root side A ₁ is the site of wings source F _1, in the present invention that is cut and separated into the chicken wings side A ₂ is a portion which remains wings in F ₂ and wings F ₃ led, as shown in FIG. 5 place the joint point G between the wing source F ₁ and wing in F ₂ as shown in (a) to the endless belt 2, so reluctant straddle by distributing the wing root side a ₁ and chicken wings side a ₂ Is.
[0018]
In general, the wing base side A ₁ and the wing tip side A ₂ have different weights, so when they are placed on the endless belt 2 and straddled, they tend to lean toward the heavy weight side. 6 acts as a stopper, maintains the posture where the joint part G rides on the endless belt 2 without tilting or falling down, and smoothly moves in one direction without being stagnated by being hooked and pushed by the protrusion 3 It is conveyed to.
[0019]
The cutting tool 11 extended in the extending direction from the end portion of the feed stroke section 2a of the endless belt 2 is provided with a flat blade body 13 on a vertical surface and provided with an upward cutting edge 14 at the upper edge. And a second blade 16 in which a flat blade body 17 is disposed on a vertical plane and a lower blade edge 18 is provided over the entire length of the lower edge of the blade.
[0020]
The blade body 13 of the first cutter 12 has leg girders 48 extending in the front-rear direction. These leg girders 48 are overlapped on the leg base 49 and are formed by a well-known mechanism comprising a slot 49a and a set screw 48a. The height position of 12 is variable.
[0021]
The upper end portion of the first blade 12 starts from substantially the same height position as the feed stroke section 2 a of the endless belt 2, and is inclined so as to gradually become higher in the extending direction of the endless belt 2. Further, the upper end edge is round at the start end portion to form the joint searching portion 15, and subsequently, the upward cutting edge 14 is formed to the vicinity of the end.
[0022]
The second cutting edge 16 is fixed with the downward cutting edge 18 substantially horizontal and overlapped with the side surface of the first cutting edge 12, so that the two cutting edges 14 and 18 gradually decrease the facing distance in the extending direction and finally cross over. To do.
[0023]
Next, in the present invention, the wings F that have been transported across the endless belt 2 are changed over in a state of straddling the first blade 12, and the joint points G are gradually swept into the upward blade edge 14 so that the wings are swept. The original side A ₁ and the wing tip side A ₂ are cut and separated.
[0024]
For this purpose, the transfer device 21 for forcibly transferring the wings F along the cutting tool 11 includes two rollers 22 a and 22 b having spiral grooves 23 a and 23 b arranged on both sides of the first blade 12. Both ends of the rollers 22a and 22b pass through the bearings of the holders 24 and 25, respectively, and are rotatably supported. The start ends of the spiral grooves 23a and 23b are located on both sides of the end portion of the feed stroke section 2a of the endless belt 2. ing.
[0025]
These two rollers 22a, 22b are rotated in the opposite directions at the same rotational speed, and the wing base side A ₁ and the wing tip side A _{2 of} the wing F transferred near the end of the feed stroke section 2a are connected to the endless belt 2 Engages and meshes with the respective spiral grooves 23a, 23b almost simultaneously with the start of the direction change. The wing F away from the endless belt 2 is in an unstable state instantaneously, but immediately starts to straddle the joint search unit 15 of the first blade 12, and even if the position is shifted at this time, the wing tip F ₁ , wing Since the middle F ₂ is bent in an inverted V shape, the posture is self-corrected so that the joint part G, which is the apex, rides on the joint search unit 15 while sliding under its own weight, and the state shown in FIG. 5B is obtained. .
[0026]
Subsequently, the wings F are forcibly transferred by the two rollers 22a and 22b, and the upward cutting edge 14 of the first blade 12 gradually bites deeply into the joint point G as shown in FIG. Proceed with cutting and finally completely cut off and fall. The height position of the first blade 12 is adjusted so that the wing base side A ₁ and the wing tip side A ₂ are in contact with their outer peripheral surfaces mainly below the central axes of the rollers 22a and 22b, respectively. The roller 22a, 22b gradually increases and is forcedly transferred without being lifted by the upward cutting edge 14 projecting upward from the rollers 22a, 22b. Further, since the first blade 12 functions as a partition between the separated wing base side A ₁ and wing tip side A ₂ , it can be recovered without being mixed.
[0027]
On the other hand, in the illustrated form, the second blade 16 is provided so as to face the first blade 12, so that the second blade 16 is cut from the opposite side during the cutting by the first blade 12 as shown in FIG. Cutting is started, and cutting can be performed with a short transfer distance. Alternatively, even if the wings F are forcibly transferred while being lifted up by the first cutter 12, the second cutter 16 can be cut in cooperation with the first cutter 12 while holding the lift and reliably cut off. it can.
[0028]
Next, the holders 24 and 25 that support both ends of the rollers 22a and 22b are adjustable in position vertically and horizontally.
[0029]
That is, the holder 24 on the start end side is attached to the tip of a screw rod 26 extending in a direction perpendicular to the direction in which the endless belt 2 and the cutting tool 11 extend, and this screw rod 26 is attached to an arm rod 27 extending in the vertical direction. By tightening nuts 28a and 28b that are passed through at right angles and screwed from both sides, the arm rod 27 is fixed so that the left and right positions, that is, the distance between the rollers 22a and 22b can be adjusted. The arm rod 27 is screwed by a screw rod 29 extending parallel to the arm rod 27 and is held by a dovetail-shaped guide member 30. When the screw rod 29 is turned, the arm rod 27 moves up and down and starts the rollers 22a and 22b. The height position of each part can be adjusted separately.
[0030]
The holder 25 on the end side is attached to the tip of a screw rod 31 extending in the same direction as the screw rod 26, and this screw rod 31 is passed through an arm rod 32 extending in the vertical direction to pass through a nut 33a, screwed from both sides. By tightening 33b, it is fixed to the armband 32 so that the left and right positions, that is, the distance between the rollers 22a and 22b can be adjusted, and the holder 25 is sandwiched between the guide rails 34 projecting from the armband 32 and is stably left and right. Moving. The arm rod 32 is screwed by a screw rod 35 extending in parallel with the arm rod 32 and is held by a dovetail-shaped guide member 36. When the screw rod 35 is turned, the arm rod 32 moves up and down and ends the rollers 22a and 22b. The height position of the part can be adjusted separately.
[0031]
With this configuration, the distance between the rollers 22a and 22b arranged on both sides of the cutting tool 11 can be changed depending on the size and shape of the wing F so that the forcible transfer can be performed in a completely engaged state, or the two rollers 22a and 22b can be performed. Therefore, it is possible to correct the posture by changing the height difference and to change the posture so that the joint can be cut appropriately.
[0032]
The two rollers 22a and 22b may be arranged in parallel to each other. However, as shown in the illustrated embodiment, the central axis of the one roller 22b is substantially the same height as the endless belt 2 of the feed stroke section 2a. It is preferable to dispose the roller 22a in a state extending in the horizontal direction, and to incline the other roller 22a so that the start end is at the same height as the roller 22b and the end end is higher than the end.
[0033]
That is, as the biting into the joint part G of the first blade 12 becomes deeper in this way, the wing base side A ₁ and the wing tip side A ₂ tend to spread, and the wing F bites the first blade 12. In addition, the disadvantage of increasing the resistance is eliminated, and it is possible to cut with a low resistance and therefore a small transfer force.
[0034]
The ends of the two rollers 22a and 22b are coupled to gear shafts 43a and 43b via a telescopic transmission shaft 41 and free joints 42a and 42b at both ends, respectively. The gears 44a and 44b of the gear shafts 43a and 43b are engaged with each other, and one gear shaft 43a is driven by a prime mover 46 through a transmission device 45 comprising a chain and a chain wheel.
[0035]
By this mechanism, the two rollers 22a and 22b rotate in the opposite directions at the same rotational speed, and therefore the wings F can be forcibly transferred in a predetermined posture. The transmission shaft 41 and the universal joints 42a and 42b expand and contract and rotate to follow the displacement from the gear shafts 43a and 43b as the rollers 22a and 22b are adjusted to the left and right and up and down, respectively. Is transmitted to the rollers 22a and 22b without any problem.
[0036]
The prime movers 4 and 46, the guide member 6, the screw rods 29 and 35, the guide members 30 and 36, the gear shafts 43 a and 43 b, and the leg base 49 are attached to the base 51.
[0037]
In addition, the endless belt 2 of the transporter 1 is not limited to a chain, and an elongated one that can straddle the wings F like a V belt can be arbitrarily used. Further, the cutting tool 11 is fixed only to the first blade 12 and the height position thereof is not adjustable, or one of the two rollers 22a and 22b is gradually raised, and their left and right and up and down positions are variable. It is possible to achieve cutting and separation of the wings F, which is an object of the present invention, even if they are parallel to each other or fixed at a certain position.
[0038]
【The invention's effect】
As described above, according to the present invention, the work of placing the wings on the endless belt of the transporter and distributing the wing base side and the wing tip side to both sides is performed manually, requiring a lot of labor and reducing the work efficiency. Because it automatically cuts the joints that caused the problem with a cutting tool and a transfer machine, it can efficiently and appropriately separate a large number of wings without requiring much skill and labor. It is.
[0039]
Further, according to the present invention, in addition to the above, smooth feeding of the wings from the transfer machine to the transfer machine, cutting with no impact and low resistance, cutting with a short transfer distance, different sizes and shapes It is possible to cut the wings appropriately.
