Description

  The present invention relates to a hair removal apparatus for meat chickens, duck, turkeys and other poultry. In particular, the present invention relates to a poultry epilation apparatus in which a plurality of epilation fingers are attached to a rotating disk.

2. Description of the Related Art Conventionally, as a depilation device for meat chickens, duck, turkeys and other poultry, a device in which a plurality of depilation fingers are attached to a disk-shaped rotating disk is known (see, for example, Patent Documents 1 to 3). . In Patent Document 1, when a disk to which a plurality of hair removal fingers are attached is rotated, a rubber hair removal finger is bent in a reverse rotation direction by a rotational force and bent outward in a radial direction by a centrifugal force, and is swept on a chicken surface. (See FIG. 7 of Patent Document 1).
Further, Patent Document 2 discloses a hair removal device in which a large number of rotating finger devices are arranged along the chicken conveyance direction. In this epilation device, rotary finger devices are arranged on the left and right sides and the lower side of the chicken. According to Patent Document 3, the rotating finger devices arranged on the left and right sides are configured to be movable in a direction approaching or separating from the chicken for each frame to which the rotating finger device is attached. By moving the mounting frame, the force for holding the chicken is adjusted for each lot. This configuration is particularly meaningful when changing the type of poultry. Hereinafter, a conventional poultry hair removal apparatus will be described with reference to the drawings.

  FIG. 11 shows an outline of a conventional poultry hair removal apparatus. As shown in the figure, the chicken bodies K are conveyed in a line. The chicken body K is arranged so that the width direction of the chicken body K and the chicken body conveyance direction are in the same direction. Hair removal apparatuses 100 are provided on both sides of the chicken body conveyance line L. Each hair removal device 100 is provided with a plurality of rotary finger devices 101. The rotary finger device 101 has a rubber epilation finger 102 for removing the feathers of the chicken body K, a disk 103 on which the epilation finger 102 is fixed, and a rotating shaft 104 for rotating the disc 103. doing. Adjacent disks 103 are paired and reversely rotated with each other. This is because when the blades of the chicken body K are dropped by the hair removal fingers 102, the adjacent disks 103 are rotated in the opposite directions to cancel the lateral force and reduce the swing of the chicken body K.

As shown in the figure, since the chicken body K has a different size for each individual, the rubber epilation finger 102 bends outward in the radial direction of the disk 103 as the chicken body K becomes thicker. A plurality of hair removal fingers 102 are provided for each disk, and the disk 103 rotates at a high speed of, for example, 1000 rpm. In the drawing, the drawing is performed without considering the bending of the epilation finger 102 due to the centrifugal force of the disk 103.
Moreover, the hair removal apparatus 100 can be moved in a direction perpendicular to the chicken conveyance direction, that is, in a direction approaching or separating from the chicken, and the installation position can be adjusted in accordance with the type of poultry.

  FIG. 12 shows a cross section in the width direction of the epilation apparatus 100. As shown in the figure, three rotary finger devices 101 are provided on each side of the chicken body K. Since the upper rotating finger device 101 is arranged at a height similar to the wing tip of the chicken body K, it is arranged slightly inclined downward in order to remove the wings of the legs. Since the middle rotary finger device 101 has the same height as the chicken body K, ie, the rounded chest and waist of the chicken body K, the epilation finger 102 is arranged along the horizontal direction. ing. Since the lower rotary finger device 101 is disposed at a height similar to the head of the chicken body K, it is disposed slightly inclined upward. Each of these rotary finger devices 101 is provided with a plurality of epilation fingers 102. For example, six are arranged along the circumferential direction of the disk 103, or eight are arranged so as to draw a square (see, for example, FIGS. 2 and 5 of Patent Document 4).

The hair removal finger 102 of the upper rotary finger device 101 comes into contact with the crotch portion or leg portion of the chicken body K and removes the blades at this portion. The hair removal finger 102 of the rotary finger device 101 at the middle stage comes into contact with the trunk of the chicken body K, such as the chest and waist that bulges round, and removes the feathers at this part. Since the epilation finger 102 is made of rubber and penetrates deep into the chicken body K, the tip side of the epilation finger 102 is curved. Since the rotary finger device 101 can move in the left-right direction, the degree of curvature of the epilation finger 102 can be increased or decreased by adjusting the rotation finger device 101. Moreover, since the size of the chicken body K is irregular and follows a normal distribution, the curved shape of the epilation finger 102 differs for each chicken body.
The hair removal finger 102 of the lower rotary finger device 101 comes into contact with the head and neck of the chicken body K and removes the feathers at this part. The rotary finger device 101 is brought into contact with the chicken body K and the hair removal finger 102 is moved around, thereby removing the hair from the whole body of the chicken body K suspended on the metal hanger 106 connected to the conveyor 105. .

  FIG. 13 shows details of the structure of the rotary finger device 101. However, the cover case is not shown. The rotary finger device 101 includes a rotary shaft 104, bearings 107A and 107B that support the rotary shaft 104, and a casing 108 in which the rotary shaft 104 is inserted and the bearing 107A is fitted. A disk 103 is attached to the tip of the rotating shaft 104 using a bolt B, and nine hair removal fingers 102 are provided on the disk 103. Three of the nine hair removal fingers 102 are provided at three locations at 120 ° intervals on the center side of the rotating plate, and the remaining six hair removal fingers 102 are provided at six locations at 60 ° intervals on the outer peripheral end side of the disk 103. Is provided.

FIG. 14 (a) shows a state before the chicken body is transported although the disk 103 is rotating. In this state, the rubber epilation finger 102 is not bent and extends horizontally. The epilation finger 102 is bent outward in the radial direction of the disk 103 by centrifugal force when the disk 103 rotates. However, FIG. 14 does not show the bending due to the centrifugal force.
When the chicken is transported, the chicken K is pressed against the epilation finger 102 as shown in FIG. 14B, and the epilation finger 102 is bent outward in the radial direction of the disk 103. In this state, the epilation finger 102 urges the chicken body K with its elastic force. And the feather | wing of the chicken body K is scraped off with the big frictional force of the hair removal finger 102. FIG. In FIG. 14B, since the bending of the hair removal finger 102 due to centrifugal force is not shown, the actual deformation of the hair removal finger 102 is added to the deformation amount shown by the centrifugal force.

  When the chicken body K that is thicker than the chicken body K in FIG. 14B is transported, the epilation finger 102 is further bent as shown in FIG. 14C. However, if the hair removal finger 102 is greatly bent, the force applied to the chicken body K increases, so that the chicken body K may be damaged. Hereinafter, the damage degree of the chicken will be described.

The cross section of the abdominal part E or the back part F of the chicken body K shown to Fig.15 (a) is shown to (b)-(f) of FIG. FIG. 15B shows a state in which the degree of damage is zero in which the chicken body K is not damaged. In this state, all goose bumps of the chicken body K remain, and there is a grip when touched by hand. The meat 110, the fat 111, and the skin 112 are attached in layers without gaps.
FIG. 15 (c) shows a state where the degree of damage is 1 or 2 where the chicken body K is slightly damaged. Here, goose bumps are a little crushed, and when touched by hand, there is a feeling of catching, although not as much as in the case of FIG. FIG. 15 (d) shows a state of a degree of damage 3 in which a relatively large damage has occurred in the chicken. The skin 112 is partially peeled off from the meat 110, and wrinkles are generated on the surface of the chicken. These wrinkles are of a level that can be recognized by hand or by eye. When the damage is further increased, as shown in FIG. 15 (e), the skin 112 is torn, the fat 111 leaks therefrom, and a blister 111A is generated. When the surface of the chicken body K is touched by hand, there is a slimy feeling. This state is the damage degree 4. As damage progresses further. As shown in FIG. 15F, the skin 112 is completely broken and the meat 110 is exposed. This state is the damage degree 5.

Japanese Patent Publication No. 45-84 Japanese Examined Patent Publication No. 45-11094 JP 49-47166 A JP-A 61-227727

In the conventional poultry hair removal apparatus, if the chicken body K is large or thick, the urging force of the hair removal finger 102 to the chicken body K becomes larger than that of the average chicken body K, and the chicken body K is shown in FIG. Damage as shown may occur. When chickens are further damaged, there is a problem that bacteria on the skin surface enter the meat 110, and the progress of decay is rapid.
On the other hand, if the chicken body K is smaller than the average chicken body K, the urging force of the hair removal finger 102 is not sufficiently transmitted to the chicken body K, and the hair removal of the chicken body K ends incompletely and the feathers remain in the chicken body K. There was a thing. Therefore, conventionally, a light chicken K and a heavy chicken K are silently treated and ignored in accordance with the weight of the chicken K suspended on the hanger 106.

  In view of the problems of the prior art, the present invention improves the yield of chickens by eliminating the damage to the chickens regardless of the size of the poultry and allowing the hair removal treatment without leaving the unhaired part. For the purpose.

The present invention has been made as a means for solving such a problem, and the poultry hair removal apparatus of the present invention comprises:
A movable part having a plurality of elastic epilation fingers, a rotary disc holding the epilation fingers, and a rotary shaft coupled to the rotary disc so as to hold the rotary disc slidable in the axial direction; A stationary part having a bearing that supports the rotating shaft and into which the rotating shaft is inserted,
In the poultry depilation apparatus in which the depilation finger that rotates is pressed against the chicken body to remove the hair,
The movable portion further includes a main rotating portion to which the rotating disk is attached, a sub rotating portion in which the rotating shaft is fitted and provided between the main rotating portion and the stationary portion, the main rotating portion, and the An elastic member provided between the sub-rotating unit and
The main rotating portion is configured to slide along the axial direction of the rotating shaft with respect to the sub rotating portion.

In this invention, a movable part provided with a hair removal finger rotates with respect to a stationary part, a rotating hair removal finger is pressed on the surface of a chicken body, and the feather of a poultry is removed by the frictional force. When a load is applied to the chicken body due to the hair removal finger coming into contact with the chicken body, the hair removal finger is first bent to prevent the load applied to the chicken body from becoming excessive. In this hair removal, even if it is thicker than the average poultry, an elastic member is inserted between the main rotating part and the sub rotating part, so if the load applied to the chicken body exceeds the critical value, the hair removal The finger moves backward. Therefore, it is possible to prevent an excessive load from being applied to the chicken. Therefore, the hair removal finger can be arranged closer to the chicken body than before, and the hair removal effect can be maintained even if the chicken body is thin.
In the conventional hair removal apparatus not provided with an elastic member, the load applied to the chicken body exceeds the critical value because only the deformation of the hair removal finger having elasticity corresponds to the size of the poultry, and the damage described in FIG. May occur in chickens.

  Therefore, in this invention, the hair removal effect of a chicken can be improved irrespective of the size of a chicken. According to the present invention, it is possible to prevent the chest and waist of the chicken from being squeezed excessively, and to reduce damage to the chicken. As a result, the invasion of bacteria into the chicken body can be reduced, so that the chicken body has a long shelf life. Moreover, it can prevent that goose bumps are crushed and fat leaks to the surface. Moreover, the problem of separation of meat and skin and the problem of wrinkles on the skin can be solved. Moreover, the problem that water bubbles are generated in the thin skin on the surface can be solved. Moreover, the skin of the surface is not cut and the meat is not exposed. Therefore, the commercial value of the chicken can be maintained.

  In the device according to the present invention, the main rotating portion and the sub rotating portion are engaged with each other, and when the main rotating portion or the sub rotating portion rotates, the sub rotating portion or the main rotating portion may be rotated. In this configuration, either the main rotating part or the sub rotating part may be connected to the rotating shaft. Thereby, the support mechanism of the elastic member by the main rotating part and the sub rotating part can be simplified.

  In the device of the present invention, a guide portion may be formed so that the main rotation portion slides along the rotation axis direction with respect to the sub rotation portion. When the guide portion is formed, the main rotating portion can be smoothly slid. For example, the main rotating part can be slid in a straight line.

  The main rotating portion and the sub rotating portion may be engaged with each other by a key portion and a key groove. Thereby, the engagement between the main rotating portion and the sub rotating portion can be ensured. Therefore, since the rotation in the clockwise direction or the counterclockwise direction can be easily transmitted between the main rotating part and the sub rotating part, it becomes easy to rotate adjacent rotating finger devices in opposite directions, and at the time of hair removal The position of the chicken can be stabilized.

  In the device of the present invention, it is preferable to provide a restricting member for restricting the movement of the movable portion on the tip side of the rotating shaft, and to provide a coupling member for covering the front side of the restricting member. By providing the restricting member, the movable part does not fall off the rotating shaft. Moreover, even if the structure of the front end portion of the rotating shaft is complicated by providing the regulating member, it is possible to prevent the blade clogging phenomenon from occurring at the front end portion of the rotating shaft due to the presence of the coupling member.

  In the device of the present invention, when a spring is used as the elastic member, a spring receiving portion into which one end of the spring is inserted may be formed in the auxiliary rotating portion. Thereby, the spring can be stably held.

  Further, in the device of the present invention, it is preferable that the rotating disk holding the hair removal finger is formed in a disk shape, and the rotating disk is inclined toward the distal end side of the hair removal finger as it goes outward in the radial direction of the rotating disk. The epilation finger having elasticity when the rotating disk rotates is bent outward in the radial direction of the rotating disk by centrifugal force. With the above-described configuration, even when the rotating disk is rotated at a high speed, the hair removal finger can be oriented toward the chicken body. Thereby, the depilation force of the feather | wing of a chicken can be increased by rotating a turntable at high speed.

In the above structure, the main rotating part has a holding part for holding the rotating disk, and a plurality of fan parts are formed by slitting the rotating disk at an angular interval set in the circumferential direction from the outer peripheral end. Furthermore, it is preferable to incline the fan portion toward the hair removal finger tip side.
Thereby, the inclination of the fan portion can be adjusted as appropriate, and it becomes easy to optimize the direction of the hair removal finger. In addition, it is inexpensive if the rotating disk is formed by press molding.
In addition to the above configuration, a horseshoe part may be formed by a curved second slit on the center side of the disk-shaped rotating disk, and the horseshoe part may be fixed to the holding part. Accordingly, if the horseshoe-shaped small piece portion is fixed to the holding portion, the inclined rotating disk can be reliably and easily attached to the holding portion, and the attachment strength can be improved.

  In the poultry hair removal apparatus of the present invention, the movable portion includes a main rotating portion to which a rotating disk is attached, a sub rotating portion in which a rotating shaft is fitted and provided between the main rotating portion and the stationary portion, and a main rotating portion. The main rotating part is configured to slide along the rotation axis direction with respect to the sub-rotating part, regardless of the size of the poultry. The hair removal part can be reduced while suppressing damage to poultry, and the commercial value of the chicken and the hair removal effect can be improved.

  Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the dimensions, materials, shapes, relative positions, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention to that unless otherwise specified.

(First embodiment)
1st Embodiment of the poultry hair removal apparatus by this invention is described based on FIGS. FIG. 1 schematically shows a hair removal apparatus of the present embodiment. As shown in FIG. 1, chickens K, which are poultry, are transported in a line. The chicken body K is arranged so that the width direction of the chicken body K and the chicken body conveyance direction are in the same direction. There are individual differences in the size of the chicken body K. The epilation device 1 is provided on both sides of the chicken conveyance line L. Each epilation device 1 is provided with four rotary finger devices 2.

  The rotary finger device 2 includes a rubber epilation finger 31 for removing the feathers of the chicken body K, a rotary disc 32 on which the epilation finger 31 is fixed, and a rotary shaft 36 for rotating the rotary disc 32. I have. When the hair removal finger 31 comes into contact with the chicken body K and a load exceeding the allowable value is applied to the chicken body K, the turntable 32 slides and retreats along the rotation shaft 36, the spring 35 is compressed, and the hair removal finger is compressed. The position of 31 varies. This prevents the chicken body K from being loaded more than the allowable value.

Adjacent rotary disks 32 are paired and rotate reversely to each other. As a result, when the feathers of the chicken body K are removed by the hair removal fingers 31, the horizontal forces applied to the chicken bodies K from the hair removal fingers 31 of the respective rotary disks 32 cancel each other, thereby stabilizing the position of the chicken body K. This is to make it happen.
Further, since the chicken body K varies in size from one individual to another, the rubber epilation finger 31 is pushed against the elastic force of the spring 35 by the chicken body K as the chicken body K becomes thicker. A plurality of hair removal fingers 31 are provided for each turntable, and the turntable 32 rotates at a high speed of, for example, 1000 rpm. In FIG. 1, the drawing is performed without considering the bending of the hair removal finger 31 due to the centrifugal force of the rotating disk 32.
Moreover, the epilation apparatus 1 is arrange | positioned so that a movement in the direction which cross | intersects a right angle with a chicken body conveyance direction is possible, and it can move an arrangement position according to the kind of chicken body K. FIG.

  2 to 5 show the structure of the rotary finger device 2. As shown in FIG. 2, the rotary finger apparatus 2 used for the hair removal apparatus 1 of this embodiment has the movable part 3 which carries out a rotational motion and a linear motion, and the stationary part 4 to which this movable part 3 is attached. The movable portion 3 has nine elastic rubber epilation fingers 31 and a disk-shaped rotary disc 32 that holds the epilation fingers 31. The epilation finger 31 has a shaft portion 31a and a head portion 31b, and a plurality of annular projections 31a1 are formed on the shaft portion 31a from the tip side. This protrusion 31a1 has the effect of increasing the frictional resistance against the chicken body surface and enhancing the sweeping action of the blades.

Further, the hair removal fingers 31 are provided at intervals of 60 degrees along the circumferential direction on the outer peripheral end side of the rotating disk 32, and three hair removal fingers 31 are provided at intervals of 120 degrees on the center side. The turntable 32 is formed by press-molding a thin plate-like metal member, and a bowl-shaped coupling portion 32a is formed at the center. Bolts B1 and washers are provided inside the coupling portion 32a. The bolt B1 is for fixing the annular regulating member 38 to the rotating shaft 36. This restricting member 38 prevents the movable part 3 from falling off the rotating shaft 36. In a state where the chicken body K does not exist, the movable portion 3 is biased by the spring 35 so as to contact the regulating member 38.
There is a gap where the blades can enter around the regulating member 38, and there is a concern about blade clogging. However, in this embodiment, the coupling portion 32a prevents the blade from entering, and thus blade clogging does not occur. Of course, instead of integrally forming the coupling portion 32a on the rotating disk 3, a coupling member may be attached separately.

The hair removal finger 31 is attached by press-fitting the shaft portion 31 a into the nine round holes 32 f formed in the rotating disk 32 until the head portion 31 b of the hair removal finger 31 comes into contact with the back side of the rotating disk 32. This is done by fitting the ring-shaped concave groove 31c (see FIG. 4) formed in the circular hole 32f.
The movable part 3 includes a main rotating part 33 attached to the turntable 32 by three bolts B4, a sub rotating part 34 provided between the main rotating part 33 and the stationary part 4, and a main rotating part 33. And a coiled spring 35 which is an elastic member provided between the auxiliary rotating portion 34. The main rotating part 33 has a function as a holding part of the rotating disk 32. A spring receiving portion 34 a into which one end of the spring 35 is inserted is formed in the auxiliary rotating portion 34. The spring 35 is stably supported by the spring receiving portion 34a.

  The stationary part 4 includes a thrust bearing 41 that supports the rotating shaft 36, an oil seal 42 that prevents water from entering, and a cylindrical casing 43 through which the rotating shaft 36 is inserted. The thrust bearing 41 and the oil seal 42 are fitted in the casing 43. A heavy pulley 37 is provided at the rear end of the casing 43. A belt (not shown) is hung on the pulley 37, and the power of a drive motor (not shown) is transmitted. By winding the belt around the pulley 37 of the adjacent rotary finger device 2 in a zigzag manner, the rotary disks 32 of the adjacent rotary finger devices 2 can be rotated in reverse to each other.

  When this pulley 37 rotates, the rotating shaft 36 rotates, and the main rotating part 33 and the turntable 32 rotate. Then, the sub-rotation unit 34 rotates with the main rotation unit 33. The pulley 37 is fixed to the rear end of the rotating shaft 36 using a bolt B2, a washer W, and a spacer 44 adjacent to the thrust bearing 41. That is, the pulley 37 is sandwiched between the washer W and the spacer 44 by the fastening force of the bolt B2. Moreover, the short ring part 45 in which the collar part 45a was formed is being fixed to the front-end | tip of the rotating shaft 36 using the volt | bolt B3.

  FIG. 3 is a perspective view of the rotary finger device 2. The rotary finger device 2 is mainly made of metal except for the hair removal finger 31, and can be made of stainless steel or aluminum alloy. The hair removal finger 31 is gradually thinned with a gentle inclination as it approaches the tip. This is because the hair removal finger 31 is fixed on the rear end side, so that it is prevented from being bent by its own weight and an appropriate urging force is applied to the chicken.

  When the rotary finger device 2 is disassembled, it becomes as shown in FIG. In FIG. 4, some components are omitted for convenience of explanation. As shown in the figure, the main rotating portion 33 is integrally formed with a three-pronged flange portion 33a and a cup-shaped cylindrical portion 33b. A spring 35 is inserted into a cylindrical space 33b1 formed in the cylindrical portion 33b. A key groove 33b2 is formed in the cylindrical space 33b1 in the axial direction. The sub rotation part 34 has a spring receiving part 34a and a dish part 34b. A key portion 34a1 is formed in the spring receiving portion 34a. A rotation shaft 36 is inserted into the main rotation portion 33 from the sub rotation portion 34 side. The rotating shaft 36 has a columnar shaft main body 36a and a protrusion 36b having a substantially square cross section formed integrally with the tip of the shaft main body 36a. The protrusion 36 b is inserted and fitted into a through hole 33 c having a substantially square cross section formed at the center of the main rotating portion 33. Thereby, when the rotating shaft 36 rotates, the epilation finger 31 rotates around the main rotating portion 33. The protrusion 36b also serves as a guide portion for the main rotating portion 33, like the key portion 34a1 and the key groove 33b2.

  As shown in FIG. 5, a key portion 34 a 1 is formed along the axial direction on the outer periphery of the spring receiving portion 34 a and engages with the key groove 33 b 2 of the cylindrical portion 33 b of the main rotating portion 33. In this case, the key part 34a1 and the key groove 33b2 correspond to the guide part. As a result, the main rotating portion 33 can smoothly move in a straight line with respect to the sub rotating portion 34. In this configuration, when the main rotating portion 33 connected to the rotating shaft 36 rotates, the sub rotating portion 34 rotates. That is, the key portion 34a1 is caught in the key groove 33b2, and the auxiliary rotating portion 34 is reliably rotated. Further, even if the main rotating portion 33 rotates clockwise or counterclockwise, the sub rotating portion 34 rotates with the main rotating portion 33. Therefore, the adjacent rotary finger device 2 (described in FIG. 1) can be reliably rotated in opposite directions, and the chicken position at the time of hair removal can be stabilized.

  FIG. 6 shows the positional relationship between the hair removal finger and the form. FIG. 6A shows a state where the rotary finger device 2 is not operating. In this state, the epilation finger 31 extends along the horizontal direction. A part of the hair removal finger 31 is not shown. When the rotary finger device 2 is activated, the rotary disk 32 rotates at a high speed of, for example, 1000 rpm, and the epilation finger 31 rotates. Then, the hair removal finger 31 made of rubber is bent outward in the radial direction of the rotating disk 32 by a centrifugal force, as shown in FIG. However, in FIG. 6C and FIG. 7, for the convenience of explanation, the deformation due to the centrifugal force is not illustrated and illustrated. Therefore, in FIG. 6C and FIG. 7, even if the rotary finger apparatus 2 is operating if there is no chicken, it is shown in FIG. 6A. Moreover, in FIG.6 (c) and FIG. 7, the continuous line of the chicken body K is an outline of the chicken body K including a wing | blade part, and a broken line shows the outline of the meat part of the chicken body K which does not include a wing | blade part.

When the chicken body K is conveyed to the front surface of the rotary finger device 2, the chicken body K and the hair removal finger 31 come into contact as shown in FIG. The feathers are peeled off from the chicken body K by the sweeping action of the rotating epilation finger 31. Since the shaft portion 31a of the hair removal finger 31 is made of rubber, it has a high coefficient of friction, and the hair removal effect can be enhanced by the catching action of the projection 31a1.
When the chicken body K is pressed against the shaft portion 31a and a load is applied to the chicken body K, the shaft portion 31a is bent and the load applied to the chicken body K is reduced. When the load applied to the chicken body K exceeds an allowable value (for example, 2.0 to 4.0 kg / cm ² ), the main rotating portion 33 is pushed in and the spring 35 is compressed. This prevents the chicken body K from being loaded more than the allowable value. The allowable value indicates a limit value in a range where the degree of damage described with reference to FIG. The permissible value is appropriately set according to the type of poultry.

Since the chicken body has various sizes, if the chicken body K larger than FIG. 6C is conveyed, the turntable 32 and the main rotating portion 33 are pushed in as shown in FIG. . Thus, in this embodiment, by providing the spring 35 between the main rotating part 33 and the sub-rotating part 34, it is possible to flexibly cope with the difference in the size of the chicken body K, and the chicken body K exceeds the allowable value. A load can be prevented. Moreover, the load which the hair removal finger 31 acts on the chicken body K can be adjusted by adjusting the hardness, elastic modulus, etc. of the axial part 31a. As shown in FIG. 2, the clearance a between the coupling portion 32 a and the bolt B <b>1> the backward stroke b of the main rotation portion 33 so that the retraction of the main rotation portion 33 is not hindered by the presence of the coupling portion 32 a. There is a need.
In addition, according to the magnitude | size of poultry, the rotation finger apparatus 2 itself can be translated in the direction orthogonal to the conveyance direction of the chicken body K, and the space | interval with the poultry conveyance path L can also be adjusted per rod.

Next, a method for assembling the rotary finger device 2 will be described with reference to FIG. As for the movable part 3, first, the rotation shaft 36 is inserted into the sub-rotation part 34 and the main rotation part 33. Next, the regulating member 38 and the bolt B <b> 1 are attached to the tip of the rotating shaft 36. Next, nine hair removal fingers 31 are press-fitted into the holes 32f of the rotating disk 32 and fixed to the main rotating portion 33 using bolts B4.
Regarding the stationary part 4, the thrust bearing 41 and the oil seal 42 are fitted inside the casing 43, and the short ring part 45 is attached to the front side of the casing 43 with the bolt B <b> 3. Next, the rotating shaft 36 of the movable part 3 is inserted into the casing 43 of the stationary part 4. Next, a spacer 44 is attached to the rear surface side of the casing 43 so as to be adjacent to the thrust bearing 41, and the pulley 37 is inserted from the rear end side of the rotary shaft 36. Next, the bolt B <b> 2 and the washer W are attached to the rear end of the rotating shaft 36, and the pulley 37 is sandwiched between the spacer 44 and the pulley 37 is fixed. Thus, the rotary finger device 2 depicted in FIG. 2 is completed.

According to 1st Embodiment mentioned above, although the movable part 3 provided with the hair removal finger 31 rotates with respect to the stationary part 4, and removes the feathers of the chicken body K, the chicken body K is large at the time of this hair removal. Even if it is thicker or thicker, the hair removal finger 31 moves in the axial direction of the rotation shaft 36 by inserting the spring 35 between the main rotation portion 33 and the sub rotation portion 34. The load exceeding the allowable value does not occur. In the conventional rotary finger device in which the spring 35 is not provided, since the size of the chicken body K can be accommodated only by the deformation of the hair removal finger 31 having elasticity, an excessive force may be applied to the chicken body K.
In this embodiment, since the size of the chicken body K can be flexibly accommodated by the presence of the spring 35, the hair removal finger 31 can be disposed closer to the chicken body K than in the past, and even if the chicken body K is small, the shaft The part 31a can be pressed against the chicken body K with an appropriate force. Therefore, regardless of the size of the chicken body K, the hair removal effect of the chicken body K can be maintained.
In the present embodiment, the spring 35 is used as the elastic member. However, although not shown, a deformable elastic body such as rubber may be used instead of the spring 35.

(Second Embodiment)
FIG. 8 shows a second embodiment of the hair removal apparatus of the present invention. In the second embodiment, only the shapes of the turntable 32 and the main rotating portion 33 are different from those in the first embodiment. Therefore, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
As shown in the figure, the turntable 32 of this embodiment has a shape that inclines toward the distal end side of the epilation finger 31 as it goes outward in the radial direction. Accordingly, all the three-pronged flange portions 33a of the main rotating portion 33 are similarly inclined.
When the turntable 32 rotates, the epilation finger 31 is deformed outward in the radial direction of the rotary disc 32 by centrifugal force, and the shaft portion 31a of the epilation finger 31 is perpendicular to the chicken body K, as shown in FIG. That is, it can be directed in the direction shown in FIG.

  In the configuration of the first embodiment, the direction of the epilation finger 31 while the rotating disk 32 is rotating is bent outward in the radial direction of the rotating disk 32 due to centrifugal force, so that it collides with the adjacent epilation finger 31 and is damaged. Or depending on the size of the chicken body K, the pressure contact force against the chicken body K may be insufficient, and the hair removal effect may be reduced. In this embodiment, since the direction of the epilation finger 31 while the turntable 32 is rotating can be directed not to the outside in the radial direction of the turntable 32 but to the chicken body side, the hair removal effect can be maintained regardless of the size of the chicken body K. At the same time, the collision with the adjacent epilation finger 31 can be prevented.

  In the present embodiment, the three-pronged flange portion 33a of the main rotating portion 33 may be molded in the radial direction of the rotating disk 32 without being inclined. In this case, a gap is generated between the flange portion 33a and the turntable 32, but the bonding strength between the turntable 32 and the flange portion 33a can be sufficiently maintained. If it carries out like this, manufacture of the flange part 33a can be simplified.

(Third embodiment)
FIG. 10 shows a third embodiment of the hair removal apparatus of the present invention. In the third embodiment, only the shape of the turntable 32 is different from the first embodiment. Therefore, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
As shown in the figure, the turntable 32 of this embodiment has three fan portions 32c by slits 32b formed from the outer peripheral end with a predetermined angular interval in the circumferential direction, and the fan portion 32c is the tip of the hair removal finger. Inclined to the side. By providing the slit 32b in this way, the inclination of the fan portion 32c can be adjusted as appropriate, and it becomes easy to optimize the direction of the hair removal finger 31 during rotation.

Further, a horseshoe portion 32e is formed by a curved second slit 32d on the center side of the disk-shaped rotating disk 32. As shown in FIG. 10 (b), the horseshoe portion 32e is not inclined, and a hole 32e1 is formed. By inserting a bolt B4 (see FIG. 2) into the hole 32e1, the turntable 32 is moved to the main rotating portion 33. Fixed. In the present embodiment, since the horseshoe portion 32e is not inclined, it is not necessary to incline the flange portion 33a, and the main rotating portion 33 of the first embodiment can be used as it is. The horseshoe portion 32e only needs to be able to fix the turntable 32 to the main rotating portion 33, and may have a small piece-like region even if it is not particularly horseshoe-shaped.
Therefore, in the present embodiment, the inclination angle of the fan portion 32c of the turntable 32 can be easily adjusted, and the flange portion 33a can be easily formed. Moreover, since the horseshoe part 32e and the flange part 33a can be connected in close contact, this connection strength can be maintained high.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that other various modifications are possible without departing from the essence thereof.

In the above-described embodiment, an example in which rubber is selected as the material of the hair removal finger 31 has been described. However, the material of the hair removal finger 31 of the present invention is not limited to rubber and may be any material having elasticity. For example, a flexible plastic can be used.

Further, in the above-described embodiment, the example in which the main rotating portion 33 and the sub rotating portion 34 are engaged with each other by the key portion 34a1 and the key groove 33b1 has been described. However, the configuration of the present invention is not limited to this. The main rotating portion 33 may be configured to be slidable with respect to the auxiliary rotating portion 34 against the spring force of the spring 35.

  In the above-described embodiment, the example in which the main rotating portion 33 rotates and the sub rotating portion 34 engaged with the main rotating portion 33 rotates along with the rotation of the rotating shaft 36 has been described. In this case, the main rotating portion 33 may be rotated. In this case, the auxiliary rotating portion 34 is fixed to the rotating shaft 36 by screws or brazing. Then, the main rotating portion 33 is not engaged with the rotating shaft 36.

In the case of the above-described embodiment, the main rotating portion 33 can slide along the protrusion 36b of the rotating shaft 36. Therefore, when the auxiliary rotating portion 34 is fixed to the rotating shaft 36, the key portion 34a1 and the key groove 33b2 are unnecessary. It becomes. However, if the projection 36b having a substantially rectangular cross section is not formed and the columnar shape is formed, the key portion 34a1 and the key groove 33b2 are necessary because the portion does not engage.
In short, when one of the main rotating portion 33 and the sub rotating portion 34 is rotated together with the rotating shaft 36, it is necessary to engage the main rotating portion 33 and the sub rotating portion 34. When both the rotating unit 34 and the rotating shaft 36 are connected and rotated, it is not necessary to engage the main rotating unit 33 and the sub rotating unit 34. However, it is preferable to form a guide portion in order to slide the main rotating portion 33 with respect to the sub rotating portion 34 stably.

  With the poultry hair removal apparatus of the present invention, the poultry hair removal effect can be maintained regardless of the size of the poultry. The present invention can be applied to all poultry hair removal. It can also be applied to livestock such as sheep by changing the size of the device.
