Description

[Detailed description of the invention] This invention is a cylindrical smoking casing called a fibrous casing filled with raw meat, and both ends are ligated with purple metal fittings such as aluminum to produce roast ham, boneless ham, etc. This invention relates to a ligature removal device for a smoking casing in smoked ham.

The applicant of the present invention has already applied for an earlier invention (Utility Model Publication No. 55-48679) of the above-mentioned ligation fitting removal device, and the earlier invention is a device installed between a pair of endless rotating bodies and fixed. The smoked ham is transferred parallel to the deck plate between a plurality of conveyor plates that are moved on the deck plate, and is slightly exposed on the deck plate in an inclined state with respect to the moving direction of the conveyor plate. The smoked ham is transferred obliquely so as to approach the side of the deck plate, and is moved at a speed higher than the moving speed of the conveyor plate. The structure is such that the smoked ham ears that have been transferred diagonally are held and transferred by a supporting conveyor that is provided on the deck and moves in the same direction and at the same speed as the conveyor plate, and also on the side of the deck plate. The ear of the smoked ham to be transferred is inserted into the horizontal groove of the guide provided along the inside of the supporting conveyor, and the purple metal fitting attached to the base of the ear is guided to the outside of the guide. The cutter provided at the end of the guide is configured to cut the base of the ear of the guided smoked ham inside the purple metal fitting.

According to this prior application, the ligature of the smoking casing can be automatically and efficiently removed, and the cut is very small, and after removing the ligature, the surface of the smoking casing can be removed using vinyl chloride. When vacuum-packaged using a resin film or the like, a product with a very good packaging finish can be obtained.

However, since smoked ham is soft and easily deformed, it is difficult to make the ligation uniform with the ligation fitting, and the ligation positions are often irregular.

Further, even when the smoked ham is transported, shocks or the like tend to cause deformation, such as the purple metal fitting being embedded in the eyebrows of the smoked ham.

In the case where the ligating metal fitting is buried within the eyebrow in this way, with the guide devised by the prior application, it is difficult to reliably guide the ligating metal fitting to the outside of the guide, which tends to lead to cutting errors.

That is, inconveniences such as cutting the ear of smoked ham on the outside of the ligating fitting, or cutting the central part of the ligating fitting and leaving a part of the ligating fitting, tend to occur.

This invention was devised to correct the above-mentioned defects, such as the uneven ligation position with the ligature fitting,
Alternatively, even if the ligating tool is buried in the scraps of smoked ham, the purpose is to provide a device that can always reliably and accurately cut the base of the ear inside the ligating tool. be.

An embodiment of the present invention will be described below with reference to four drawing numbers.

a, 37 b.

In each edge cutting device 32a, 32b, each pair of supporting conveyors 33a, 33b and 34a, 34b are arranged in parallel with both endless chains 29a, 29b at positions outside of each pair of guides 35a, 35b and 36a, 36b (7). Each pair of clamping conveyors 33a, 33b and 34a, 34b is configured to move in the same direction and at the same speed as the conveyor plate 30.

Also, on the deck plate 22, from the starting end side to the starting end side of one edge cutting device 32a, and from the terminal end side of one edge cutting device 32a to the other edge cutting device 32b.
A pair of conveyors 38a and 38b are arranged toward the starting end of the conveyor belt.

Note that these conveyors 38a and 38b are arranged horizontally, slightly exposed on the deck plate 22 through a pair of openings 39a and 49b provided in the deck plate 22, and in this case, one side is shown in FIG. The second conveyor 38a is tilted at a predetermined angle θ in the direction of arrow b with respect to the moving direction of conveyor play} 30 (direction of arrow a), and the other conveyor 38b is tilted at a predetermined angle θ in the same direction of arrow C. is inclined to.

These conveyors 38a and 38b are configured to be moved at a speed greater than the moving speed of the conveyor plate 30 in the respective inclination directions (directions of arrows b and c).

Also, on the deck plate 30 are both ear cutting devices 32a, 3.
A pair of sub-plates 40a facing the sides of 2b,
40b is fixedly arranged horizontally.

The starting ends of these sub-plays }40a, 40b are arranged so as to straddle the tops of the end ends of the conveyors 38a, 38b, and the conveyor plate 30 is not collided with these sub-plays }40a, 40b. The upper part of these parts is configured to move.

In addition, a pair of pressing mechanisms 41 a and 41 b are arranged at positions corresponding to the upper portions of both sub-players } 40 a and 40 b and close to both ear cutting devices 32 a and 32 b, and the conveyor plate 30 is also operated by these pressing mechanisms. 41 a,

Next, smoked ham 44 such as roast ham and boneless ham.
As is well known, smoked ham uses a smokable smoking casing called a fibrous casing (hereinafter simply referred to as casing) in order to process the raw meat appropriately and then smoke it. ) 45 to form a cylindrical shape, and both ends thereof are ligated with a pair of ligating fittings 46a, 46b such as aluminum.

First, when shaved smoked hams are placed side by side on the supply chute 23, they roll under their own weight onto the deck plate 22.
The conveyor plate 30 is dropped onto the starting end of the conveyor plate 30 and is moving in the direction of the arrow a along this loading plate 22.
are supplied sequentially in between.

Then, the smoked ham is pushed by the conveyor plate 30 and transferred in parallel to the direction of arrow a while rolling on the deck plate 22.

And the smoked ham 44 is on one side conveyor 38.
Since the moving speed of the conveyor 38H is higher than the moving speed of the conveyor plate 30, the smoked ham 44 is moved in the direction of arrow C (the opposite direction to the direction of rolling and rotation on the deck plate). ) is given the rotational force.

Moreover, since the conveyor 38a has been moved in the direction of the arrow b, the smoked ham 44 has no conveyor plate 3.
A moving force in the direction of arrow d perpendicular to the direction of arrow a, which is the moving direction of the smoked ham 44, is applied, and a helical rotational force is applied to the smoked ham 44 by the resultant force of these forces.

The smoked ham 44 is pushed by the conveyor plate 30 while making a helical rotational movement, and is conveyed diagonally so as to gradually approach the starting position of one edge cutting device 32a.

The smoked ham 44 that has reached the starting end position of the one edge cutting device 32a is cut into one edge 45 of the casing 45.
a is inserted into a laterally described horizontal groove between a pair of guides 35a and 35b, and the lug 45a is inserted into a pair of supporting conveyors 33.
It is clamped from above and below at points a and 33b.

Since both gripping conveyors 35a and 35b are moved in the same direction and at the same speed as the conveyor plate 30, from now on, the smoked ham will be shaved while the ear 45a is being gripped.
It is pushed by the conveyor plate 30 and translated in the direction of arrow a.

Incidentally, just before the smoked ham 44 is supported by its ears 45a, it rides on the sub-plate 40a and is advanced by sliding on the sub-plate 40a.

While the smoked ham is being transported with its ear 45a supported, one ligature fitting 46a attached to the base of the ear 45a is connected to both guides 35a, 35b.
, and the fitting 46a is guided to the outside (downward side in FIG. 1) of both guides 35a and 35b.

Then, the smoked ham will be shaved by both guides 35a and 35.
When the ear 45 reaches the terminal end of the ligation fitting 46a, one cutter 37a' provided at the terminal position is used.
The base of 8 is automatically cut, and the ligature fitting 46a is removed from each ear 45a.

The smoked ham 44 is then subsequently placed on the other gathering conveyor 38b.

Then, as described above, while being rotated in the direction of arrow C, it is now transferred in the direction of arrow e, and is then transferred diagonally toward the starting position of the other edge cutting device 32b while being rotated.

Then, the other edge cutting device 32b performs the same operation as the one edge cutting device 32a described above.
The other ear 45 of the casing 45 of the smoked ham 44
The base of the ligating fitting 46b is automatically cut inside the other ligating fitting 46b, and the ligating fitting 46b is removed from each ear 45b.

After this, the smoked ham 44 is transferred to the conveyor plate 30.
is continuously transferred in the direction of arrow a to the discharge chute 2.
It is discharged at 4.

Next, as shown in FIGS. 3 and 4, one of the gathering conveyors 38
Explain a.

Note that the other conveyor 38b has the same structure, so its explanation will be omitted.

First, the gathering conveyor 38a is a belt conveyor, and a rotating belt 49 is connected to a pair of rollers 50a, 50.
These rollers 50a, 50b
When one of the two is rotationally driven, it is configured to be rotated in the direction of arrow b.

A plurality of protrusions 51 are provided on the surface of the rotary belt 49 at regular intervals in the longitudinal direction of the rotary belt 49, and these protrusions 51 are parallel to the conveyor plate 30. It is set in.

According to the gathering conveyor 38a configured as described above, the rotary belt 49 is connected to the conveyor plate 3 as described above.
The rotating belt 49 is rotated at a higher speed than the conveyor plate 30 in the direction of the arrow b, which is inclined at a predetermined angle θ with respect to the direction of movement of the belt 49 (the direction of the arrow a).
A plurality of protrusions 51 on the surface of the smoked ham 44 contact in parallel over a long range in the longitudinal direction, and these protrusions 5
1 hooks the smoked ham 44 and rotates it.

Therefore, the contact resistance between the rotary belt 49 and the smoked ham is extremely large, and in order for the smoked ham 44 to be reliably rotated in the direction of the arrow C and reliably transferred in the direction of the arrow d, the smoked ham is extremely difficult to contact. A reliable helical rotational force is applied, and the smoked ham is peeled off from one edge cutting device 32 while being pushed by the conveyor plate 30.
It is transported diagonally very quickly toward the starting end position of point a.

As described above, according to this conveyor 38H, the helical feeding speed of the smoked ham 44 is very high, and the smoked ham 44 can be helically fed extremely quickly over a short transfer distance by the conveyor plate 30.

As a result, even if the length of the gathering conveyor 38a is sufficiently shortened, the smoked ham 44 can be helically fed extremely effectively.

Next, as shown in FIGS. 5 to 9F, one edge cutting device 32 is
Explain a.

Note that the other edge cutting device 32b has the same structure, so
The explanation will be omitted.

First, the pair of upper and lower supporting conveyors 33a and 33b are each connected to a pair of front and rear sprockets}53a, 53b and 54a, 54b.
A pair of endless chains 55a, 5 horizontally wound between them.
5b.

As shown in FIGS. 9A to 9F, these endless chains 55a and 55b are arranged with their positions slightly shifted in the left and right direction, and are also arranged in a state in which they are slightly pressed against each other from above and below. .

The pressing surfaces of these endless chains 55a and 55b are set at the height of the center line P of the smoked ham 44.

Also, either one of the nozzle sprockets 53a, 54a or 53
The endless chains 55a, 55b are rotated in the same direction at the same speed as the conveyor plate 30 by rotating the chains b, 54b.

Next, the upper and lower pair of guides 35a and 35b are connected to the endless chain 5.
5a, 55b and the conveyor plate 30, and these two guides 35a, 35b are arranged vertically and symmetrically with respect to the center line P, and between these two guides 35a, 35b. A horizontal lateral groove 56 is formed on the surface.

Note that the starting ends (left end in FIG. 5) of these guides 35a, 35b are vertically inclined entrance guide portions 57a, 57.
It is shaped like b.

By the way, the rear sides of the entrance guide portions 57a and 57b of both guides 35a and 35b are constructed in a shape that is almost vertically symmetrical to each other. This will be explained using Figure F.

First, a vertical side surface of the lower guide 35b on the conveyor plate 30 side is configured as a first guide portion 59. As shown in FIG.

As the first guide portion 59 advances in the moving direction of the conveyor plate 30 (direction of arrow a), the support conveyor 33a
, 33b, and the rear side of the slope is connected to both support conveyors 33a, 33b.
3b is parallel to the plane 59a.

Next, a second guide part 60 is provided on the upper surface of the lower guide 35 b at a position on the rear side from the terminal end of the first guide part 59 .

The second guide part 60 is wedge-shaped and is integrally formed with a predetermined height h1 higher than the upper edge of the first guide part 59.

Of the left and right sides of the second guiding portion 60, the vertical side surface on the side of both supporting conveyors 33a and 33b gradually approaches both supporting conveyors 33a and 33b as it advances in the moving direction of conveyor plate 30 (direction of arrow a). The vertical side surface 60b on the conveyor plate 30 side is flush with the parallel surface 59a.

Next, on the upper surface of the lower guide 35b, there is first a first guiding part 5.
A recess 61 cut a predetermined height h2 below the upper end edge of the first guiding portion 59 is provided on the starting end side of the first guiding portion 59, and the rear side of the recess 61 is provided with a recess 61 for supporting conveyors 33a, 33b. An inclined surface 62 is provided which gradually becomes lower as it approaches.

Next, slits 63a and 63b biased toward the conveyor plate 30 are provided at the terminal ends of both the upper and lower guides 35a and 35b, and the one cutter 37a is disposed within both of these slits 63a and 63b. There is.

Note that the cutter 37a is the slit in the lower guide 35b.
36b, and a movable blade 66 that is rotatably driven in the vertical direction about a fulcrum shaft 65.

According to the edge cutting device 32a constructed as described above,
As mentioned above, when the smoked ham 44 that has been pushed and moved diagonally by the conveyor play 30 while performing the helical rotation movement reaches the starting position of the edge cutting device 32a, first the smoked ham 44 is One ear 45a of the casing 45 is guided between the entrance guide portions 57a and 57b of both guides 35a and 35b, and these two guides 35
It is inserted into the horizontal groove 56 between a and 35b.

The inserted ear 45a is first inserted into the ear 9A- in FIG.
At position 9A, as shown in FIG. 9A, it is guided between both endless chains 55a and 55b and is clamped between them from above and below.

From then on, the smoked ham 44 has its ears 45a held between the endless chains 55a and 55b.
In this state, the cutter 37 is pushed by the conveyor plate 30.
It is transported in parallel to the cutting position indicated by a.

At this time, first, at the position 9B-9B in FIG. 8, as shown in FIG.
An arrow f indicates a direction in which the shoulder 45C is relatively abutted against the first guide part 59 of the chain 35b and moves away from the endless chains 55a and 55b as the first guide part 59 inclines.
gradually being pushed in that direction.

However, due to the pressing action of the shoulder 45C by the first guide portion 59 of the lever, the ear 45a, which was initially loose as shown in FIG. As it progresses from position 9C to position 9C in Figure 8, it is gradually pulled as shown in Figures 9B to 9C, and immediately after position 9C to 9C in Figure 8, the ear 45
The tension state of a becomes maximum.

Then, due to the pulling action of the ears 45a, one of the ligation fittings 46a is separated from the shoulder 45C.
Even if the ligature fitting 46a is buried in the shoulder 45C as shown in Fig. A, the ligation fitting 461 is surely pulled away from the shoulder 45C as shown in Figs. 9B and 9C. It turns out.

On the other hand, the ligation fitting 46a is connected to the recess 6 of both guides 35a and 35b.
1 and rides on an inclined surface 62, and by the guiding action of the inclined surface 62, an energizing force is applied to the side approaching both endless chains 55a, 55b.

In other words, the direction of the ligating fitting 46a when the ear 45a is held between the endless chains 55a and 55b (the ligating fitting is wound into a roughly oval shape and crimped, and its major axis and There is a large difference from the short axis, and the direction referred to here refers to the long axis direction.

) is not constant at all. For this purpose, there is a ligature fitting 46 inside.
As for the direction of the ligature a, there are some that are vertical and have both upper and lower ends abutted against an inclined surface 62, and in this case, the inclined surface 62 connects the ligation fitting 46a to both endless chains 55a, 5.
Guide to the 5b side.

Next, at the position shown in FIG. 8, 9D-9D, as shown in FIG.
The second guiding portions 60 of a and 35b are inserted relative to each other by a wedge action.

At this time, the shoulder 45C and the ligature fitting 4 have already been connected as shown in Fig. 9C.
Since a gap 47 is formed between the ear 45a and the ear 45a above and below the ear 45a, the second guiding portion 60 is inserted into the gap 47 very reliably.

Next, as shown in FIG. 9E at the position of FIG. 8 9E-9E, the purple fitting 46 a is pressed relatively to the inclined surface 60 a of the second guide portion 60, and the inclined surface 60 a
As a result, it is gradually pressed in the direction of arrow g, which is the direction in which it approaches both endless chains 55a and 55b.

As a result, the gap 4 between the shoulder 45C and the ligation fitting 46a
7 will definitely be expanded further.

Next, as shown in FIG. 9F at position 9F-9F in FIG.
7a is reached, and the base of the lug 45a is securely inside the purple fitting 46H in the gap 47 between the movable blade 66 and the fixed blade 64, which are rotated from above to below. Cut accurately.

Next, as shown in FIGS. 10 and 12, the upper guide 35
An entrance guide 68 is attached to the side surface of the entrance guide section 57H on the conveyor plate 30 side.

The entrance guide 68 is made of a plate spring material, and has long holes 69 at two places on its front end side (supply chute side), and screws 70 and nuts 71 inserted into each of these long holes 69. It is attached to the entrance guide part 57a so as to be vertically movable and adjustable.

Also, the rear end side (discharge chute side) of this inlet guide 68,
Nut 72 fixed to inlet guide portion 57H at
The tip of the adjustment screw 73 inserted into the entrance guide 68
By adjusting the adjusting screw 73, the artificial guide part 57H is bent inward (toward the conveyor plate side) against elasticity.

By the way, as described above, this entrance guide 68 is arranged so that the smoked ham that has been obliquely transferred while undergoing a helical rotational movement reaches the starting end position of the ear cutting device 32H, and the ears 45a are connected to both entrance guide portions 57a. , 57b, and immediately before the ears 45a are held between the endless chains 55a and 55b, the eyebrows 45 of the smoked ham 44
Both endless chains 55a, 55b are in relative contact with C.
and the smoked ham 44 (Figs. 11 and 13)
(see figure).

Therefore, when the entrance guide 68 is moved and adjusted up and down along both elongated holes 69 as shown by imaginary lines in FIGS. Therefore, the contact position of the shoulder 45C with respect to the entrance guide 68 is adjusted, and the above-mentioned distance L is finely adjusted.

Further, as shown by the imaginary lines in FIGS. 12 and 13, when the rear end side of the entrance guide 68 is adjusted by adjusting the deflection using the adjustment screw 73,
Similarly, the spacing is finely adjusted.

However, by adjusting the distance L between the endless chains 55a, 55b and the smoked ham 44 in this way, the supporting position of the lug 45a by the endless chains 55a, 55b can be adjusted. like,
The second guide portions 60 of both guides 35a, 35b are securely inserted between the shoulder 45C of the smoked ham 44 and the ligation fitting 46a, and the ear 45 is inserted inside the ligation fitting 46a.
The base of a can be reliably cut.

Next, one of the pressing mechanisms 41a will be explained with reference to FIGS. 5, 6, and 14.

Note that the other pressing mechanism 4lb has the same structure, so its explanation will be omitted.

First, a fixed frame 76 is provided horizontally at a position corresponding to the upper part of the sub-player 40a and close to the edge cutting device 32a, and a conveyor player is installed below the fixed frame 76.
Pressing plates 77, 78, and 79 divided into three are arranged in the moving direction of 30 (direction of arrow a).

The front pressing plate 77 is arranged on one side of the starting end position of the edge cutting device 32a, and is attached to the upper part of the fixed frame 76 via a bracket 80 and a horizontal fulcrum pin 81 so as to be able to freely rotate in the vertical direction. It is pivotally supported.

The front pressing plate 77 has a pair of pins 82 fixed to the upper part of its front end and the upper part of the fixed frame 76. 83
The stopper 85 fixed to the bracket 80 is rotated clockwise in FIG.
It is regulated in an inclined state as shown in the figure.

Further, the intermediate pressing plate 78 and the rear pressing plate 79 are connected to the edge cutting device 3.
It is arranged horizontally on one side of the intermediate position and the terminal position of 2a.

And these pressing plates 78. 79 is a fixed frame 76
4 and 3 lifting pins 86.
A bracket}88.89 and a horizontal fulcrum pin 90. It is rotatably supported via 91.

Note that each lifting pin 86. 87 are inserted through holding cylinders 92 and 93 fixed on the fixed frame 76, respectively, so as to be able to move up and down in the vertical direction, and at the lower part of the fixed frame 76, these lifting pins 86. Spring 94 fitted around the outer periphery of each spring 87 . 95, it is biased downwardly.

Note that each lifting pin 86. At the upper end of 87 is a washer 96 that prevents it from coming off downward. 97 is fitted.

Further, front ends 78a and 79a of both pressing plates 78 and 79 are bent upward to form a curved shape.

The front edge 40a' of the sub-plate 40a is parallel to the conveyor plate 30.

According to the pressing mechanism 41a constructed as described above, the smoked ham 44, which has been pushed and obliquely transferred by the conveyor plate 30 while performing the helical rotation movement as described above, is transferred to the edge cutting device 32. Immediately before the ear 45a reaches the starting position of a and is held by the supporting conveyors 33a and 33b, the smoked ham play is performed as a sub-play} 4
The smoke remover ham 44 contacts the lower end of the front pressing plate 77 and pushes it against the spring 84 and rides on the top of the front edge 40 a'.
It advances by rotating counterclockwise as shown by the imaginary line in the figure.

Therefore, at that time, the smoked ham 44 is pressed in parallel to the front surface of the conveyor plate 30 by the pressing reaction force of the front pressing plate 77.

At this time, since the front edge 40a' of the sub-plate 40a is also parallel to the conveyor plate 30, the smoked ham 44 becomes parallel to the conveyor plate 30 by abutting the smoked ham shaver against the front edge 40a'. His posture was corrected.

Therefore, after the smoked ham is corrected in its posture to be parallel to the conveyor plate 30 (at right angles to the both supporting conveyors), its ears 45a are held between the both supporting conveyors 33a and 33b.

After this, the smoked ham 44 is supported with its ears 45a by the supporting conveyors 33a and 33b, and the smoked ham 44 is held by the supporting conveyors 33a and 33b.
While being transported to the cutting position by a, the smoked ham 44 pushes the intermediate pressing plate 78 and the rear pressing plate 79 against these plurality of springs 94. 95 and moves upward as shown in the imaginary line in FIG. .

At this time, each pressing plate 78. 79 is each lifting pin 86.8
7 and each fulcrum pin 90. In combination with the rotational movement about 91, the upper part of the smoked ham shaver is successively passed through in a wavy motion.

However, these pressing plates 78 and 79 may be configured to move up and down in the same manner as the front pressing plate 77.

As described above, according to this pressing mechanism, both gripping conveyors 33a, 3
The smoked ham 44 can be reliably held in a state parallel to the conveyor plate 30 while the smoked ham shaved ears 45a are held by the cutter 3b and transferred to the cutting position by the cutters 37a.

That is, due to the vibrations during the above-mentioned transfer, the other ear 45b side of the smoked ham peeler is moved forward or backward centering on the supported ear 45a side, and the smoked ham 44 is moved against the conveyor plate 30. unexpectedly tilted,
And it was tilted - one ear 45 a is cut 37
It is possible to reliably prevent diagonal cutting at point a.

Therefore, the selvage 45a can always be accurately cut at right angles with the cutter 37a, and the cut end of the selvage 45a can be made to the minimum size.

Next, one cutter 37a will be explained with reference to FIG.

Note that the other cutter 37a has the same structure, so its explanation will be omitted.

First, the fixed blade 64 is fixed to the lower guide 35b.

The movable blade 66 is pivotally supported by a fixed bracket 100 via a fulcrum shaft 65 so as to be freely rotatable in the vertical direction.

A roller 102 is rotatably pivoted to the upper end of a roller mounting plate 101 fixed to the movable blade 66.

On the other hand, a rotary cam 103 that rotates the movable blade 66 up and down is fixed to a rotary drive shaft 104 and rotated together.

This rotary cam 103 is provided with an endless cam groove 105, and the roller 10 is inserted into the cam groove 105.
2 is loosely fitted.

A convex portion 10 is formed on a part of the inner circumferential surface 105a of the cam groove 105.
6 is provided, and a recess 107 opposite thereto is provided on the outer peripheral surface 10.
5b.

According to the cutter 37a configured as described above, the clockwise rotation of the rotary cam 103 causes the roller 102 to
is guided by the cam groove 105, and when the protrusion 106 on the inner peripheral surface 105a presses the roller 102, the movable blade 66
is rotated counterclockwise as shown by the imaginary line, and cuts the ear 45a of the smoked ham between it and the fixed blade 64.

After cutting, the roller 102 is pulled up by the outer peripheral surface 105b of the cam groove 105, and the movable blade 66 is rotated clockwise as shown by the solid line.
One cutting operation is performed for every rotation of No. 3.

However, according to the lever cutter 37a, the movable blade 66 can be forcibly pulled back (pull up) upward by the rotary cam 103 immediately after cutting the ear 45a of the smoked ham 44.

Therefore, even if for some reason the cutter 37a cuts the central part of the smoked ham ligation fitting 46a and the cut pieces are accidentally caught between the movable blade 66 and the fixed blade 64, As a result, the movable blade 66 will not be unable to return upward at all, and when the movable blade 66 is forcibly pulled back upward, the cut pieces caught between the movable blade 66 and the fixed blade 64 will be removed. It can be reliably pulled out and removed from between.

Therefore, it is possible to reliably prevent the inconvenience of the cutter 37a becoming inoperable due to the cutting fragments of the ligation fitting 46a being caught in the ligation fitting 46a, and to remove the ears 45a of the smoked ham 44 that are being transferred one after another. The ligation fittings 46a can be reliably removed by sequentially cutting the ligation fittings 46a.

In addition, in the embodiment described above, the binaural cutting device 32a
, 32b and both the pressing mechanisms 41a, 41b are respectively attached to a lifting platform (not shown), and the height of the entire structure relative to the deck plate 22 can be adjusted up or down according to the thickness (diameter) of the smoked ham 44. It is arranged so that it can be used.

Although the embodiments of the present invention have been described above, the endless rotating body and supporting conveyor referred to in the present invention are not limited to those using the endless chain shown in the embodiments, but may also be used, for example, using an endless belt. Various other changes can be made based on the technical idea of the present invention.

As mentioned above, the present invention involves inserting the ear of a smoked ham that is transported on a conveyor plate into the horizontal groove of the guide in order to cut the base of the ear with a cutter between the shoulder of the smoked ham and the purple fitting. When the outer end of the ear is supported by the supporting conveyor and transferred to the cutting position by the cutter, first, the ear is moved by the first guide part provided on the upstream side of the guide in the direction of movement of the conveyor plate. , by guiding the smoked ham's eyebrows in a direction that gradually moves away from the supporting conveyor, the ear is pulled relatively between the supporting conveyor and the shoulder, and the constricting metal fitting is forced outward from the shoulder. Try to pull them apart.

``As a result, even if the ligature fitting is buried in the debris, the ligation fitting can be reliably pulled outward from the shoulder meat, making it easier to introduce the second guiding part later.'' Preparations are made for introducing the second guiding portion by ensuring that a suitable gap is formed between the ligating fitting and the shoulder.

Next, following this, a second guide part, which is provided subsequent to the first guide part on the downstream side of the guide in the moving direction of the conveyor plate, is attached to the ligation fitting shaped by the separating process. The ligation fitting is easily and reliably introduced into the gap between the ear and the shoulder, and the second guide portion guides the ligation fitting in a direction that gradually approaches the supporting conveyor side, thereby relatively pulling the base of the ear. The gap between the fitting and the eyebrow is further gradually enlarged, and the base of the ear is reliably and accurately cut by the cutter within the enlarged gap.

Therefore, according to the present invention, even if the ligation positions of the ligating fittings are uneven, or the tying fitting is buried in the shoulder meat of the smoked ham, the base of the ear can be tied inside the tying fitting. This allows you to always cut reliably and accurately, eliminating cutting errors.

Therefore, it is possible to prevent the occurrence of defective products due to errors in cutting the ears, and it is possible to mass-produce the best products.
