Description

 Description Sausage manufacturing equipment

Technical field

 The present invention relates to an apparatus for producing sausage, and particularly to an apparatus for producing sausage by filling natural intestines such as sheep intestine and pig intestine as a casing with raw materials. Background art

 In this type of sausage manufacturing apparatus, when the raw material is filled in one natural intestine casing, the discharge of the raw material from the raw material discharge end of the filling nozzle is temporarily stopped, and a new empty natural intestinal case is produced. The shingle is loaded into the filling nozzle, and then the discharge of the raw material from the raw material discharge end of the filling nozzle is resumed, so that a new empty natural intestine casing is filled with the raw material.

Conventionally, for example, Japanese Patent Application Laid-Open No. Hei 6-7073 (corresponding US Pat. No. 5,480,346) and Japanese Patent Application Laid-Open No. Hei 9-26673 (corresponding US Pat. No. 88563) and Japanese Patent Application Laid-Open No. H08-103206 (corresponding U.S. Pat. No. 5,830,050) 〖As disclosed, the filling nozzle is not axially related to the filling nozzle. The rear end of the natural intestine casing that has been shrunk and applied is detected by a photoelectric detector, and the raw material discharge end of the filling nozzle is automatically detected based on the detection signal from this detector. The discharge of the raw material from this is stopped. In this technique, the distance that the natural bowel casing is extended in the axial direction is uncertain to detect the trailing end of the natural bowel casing that is attached to the filling nozzle and contracted axially. become _t result difficult not accurately perform the discharge halt in filling Roh nozzle with respect to the filling completion time of the single natural Chokeichi Thing.

 In addition, when the natural intestine casing is extended and the boundary between the surface of the filling nozzle and the rear end of the natural intestine casing is detected as a step, the coating thickness of the natural intestine casing is extremely small. It is difficult to achieve detection accuracy.

 In addition, if a photodetector consisting of a light emitter that emits red or infrared substantially monochromatic light and a photodetector that is particularly sensitive to this red or infrared substantially monochromatic light is used, the surface of the filling nozzle and the natural intestine case The difference between the two colors at the boundary with the rear end of the ring is detected by the photoelectric detector as the change in the light amount of only the red or infrared monochromatic component, so the change in the light amount is small. However, it is difficult to achieve high detection accuracy as described above.

The present invention has been made in view of the above-described points, and has as its object to meet the timing of completing the filling of raw materials into natural intestine such as sheep intestine and pig intestine used as casing. As a result, it is possible to accurately stop the discharge with the filling nozzle, so that the raw material is not discharged into the natural intestinal casing and the raw material is discharged from the filling nozzle wastefully. In addition to the above, it is possible to eliminate the disadvantage that the raw material is not filled up to the substantially rear end of the natural intestine casing. An object of the present invention is to provide a device for manufacturing a sausage which can improve the efficiency of use of the packaging. Disclosure of the invention

 The sausage manufacturing apparatus according to the first aspect of the present invention is configured such that the natural intestinal casing contracted in the axial direction is attached to the outer peripheral surface, and is rotated around the axis. From the filling nozzle and the raw material discharge end of the filling nozzle, the shrinkage in the axial direction of the natural intestinal casing applied to the outer peripheral surface of the filling nozzle At any position up to the axial end of the region, the passage of the rear end of natural intestinal casing that is moved forward from the raw material discharge end toward the raw material discharge end on the filling nozzle while being detected from the raw material discharge end is detected. A detecting means, and the supply of the raw material to the filling nozzle is stopped based on the detection result of the detecting means.

 In a sausage manufacturing apparatus according to another aspect of the present invention, in the sausage manufacturing apparatus according to the first aspect, the detecting means irradiates light to a position for detecting passage of the rear end of the natural intestine casing. And a light receiver for receiving reflected light from a position where passage of the rear end of the natural intestine casing is detected.

ADVANTAGE OF THE INVENTION This invention can perform discharge stop with a filling nozzle accurately with respect to the completion time of filling of a raw material into a natural intestine casing, and, therefore, a raw material is not filled in a natural intestine casing. Can be eliminated in vain, and Further, contrary to the above, the disadvantage that the raw material is not filled up to almost the rear end of the natural intestinal casing can be solved, and the utilization efficiency of the natural intestinal casing can be improved.

 A filling nozzle 6 made of stainless steel or the like and having an outer peripheral surface 3 is adapted to be rotated in the R direction by rotating means (not shown). The raw material is supplied by the raw material supply means 16. Such a rotating means and a raw material supply means are well known in Japanese Patent Application Laid-Open No. Hei 9-266673 (corresponding US Pat. No. 5,788,563), and therefore, detailed description thereof is omitted. I do.

Natural intestine casing 2 abuts on rear end 1 2 during raw material filling The material is pushed toward the raw material discharge end 5 automatically or manually as necessary by the intestinal pushing color 21.

 In this example, the braking means 10 contacts the outer peripheral surface of the natural intestine casing 2 attached to the outer peripheral surface 3 of the filling nozzle 7 with an annular inner peripheral edge to discharge the raw material of the natural intestinal casing 2. In addition to braking the movement in the direction toward the end 5, at least one, in this example, two, which rotates in the same direction as the rotation of the filling nozzle 7, that is, rotates in the R direction to impart rotation to the natural intestine casing 2, Annular braking members 22 and 23 made of rubber or the like, and are disposed closer to the distal end 9 in the axial direction A than the rotating braking members 22 and 23. As in the case of 3, at least one piece of the natural intestinal casing 2 comes into contact with the outer peripheral surface of the natural intestinal casing 2 at the inner peripheral edge to brake the movement of the natural intestinal casing 2 in the direction toward the raw material discharge end 5. In the example, it has an annular non-rotational drive control member 24 made of rubber or the like. The rotating braking members 22 and 23 and the non-rotating driving braking member 24 can also be formed of metal such as stainless steel or plastic.

The rotation braking members 22 and 23 are fixed to the pulley 27 at the outer peripheral edge thereof through a cylindrical mounting member 25 and a cylindrical filling nozzle anti-rotation device 26. The shaft 27 is rotatably supported in the R direction by a housing 29 via a bearing 28, and is rotatable in the R direction by a belt 30. With the rotation of, the rotation braking members 22 and 23 become Rotated in the R direction. Such a rotating means for rotating the pulley 27 is well known in Japanese Patent Application Laid-Open No. Hei 9-2666753 (corresponding US Pat. No. 5,788,563), and will be described in detail. Is omitted. The rotation braking members 22 and 23 may be configured not to be rotationally driven by the pulley 27 but to be rotationally driven by the filling nozzle 7.

The non-rotating drive braking member 24 is rotatably mounted on a support member 36 via a cylindrical mounting member 35, and the support member 36 is pivotally connected to a guide rail 37 at its lower end. The position of the support member 36 on the guide rail 37 is fixed by a thumb screw 38. The detection means 13 is A casing 41 having a light emitting device and a light receiving device, in which the light emitting device and the light receiving device are physically accommodated, is covered with a cover 4 via a bracket 42 extending toward the filling nozzle 7. The cover 40 is provided on the device frame 43 via a hinge 44 so as to be openable and closable. The light emitting device of the detecting means 13 irradiates light to the position 11 which is any position from the raw material discharge end 5 of the filling nozzle 7 to the rotation braking member 22, and the light receiving device of the detecting means 13 Receives the reflected light from position 11. The casing 41 is mounted on the bracket 42 such that the optical axis of each of the light emitter and the light receiver is at an angle に 対 し て with respect to the normal to the axis 6. The cover 40 has a shielding plate 39 extending downward, and the portion extending toward the filling nozzle 7 of the shielding plate 39 and the bracket 42. Prevents water scattered from the rotating natural intestine casing from adhering to the light-emitting and light-receiving surfaces of the casing 41.

 The light-emitting device of this example includes three light-emitting elements that emit the three primary colors of light, that is, red, green, and blue light, and the light from these three light-emitting elements is located at position 11. The light receiver of this example corresponds to the light-emitting device, responds to each of the three primary colors of red, green, and blue light, and responds to the received color intensity. Three photoelectric conversion elements for generating the detected electric signals are provided, and the electric detection signals from the three photoelectric conversion elements are electrically added. Thus, the detecting means 13 detects the passage of the rear end 12 of the natural intestinal casing 2 from the added electric signal from the photoelectric conversion element of the light receiver at the position 11. .

 The pulling means 14 fills the natural intestinal casing 2 filled with the raw material 4 with a narrowing section forming means 46 for forming a narrowing section 45 and the narrowing section forming means 46 in forming the narrowing section 45. A moving means 47 for moving the nozzle 7 rightward in FIGS. 1 and 2 so as to be away from the material discharge end 5 of the nozzle 7 is provided.

 The pulling means 14 can use a known device as described in JP-A-9-1266673 (corresponding to U.S. Pat. No. 5,887,563). Is omitted.

The pulling means 14 pulls the narrowed part 45 of the natural intestinal casing 2 by moving the narrowed part forming means 46 by the moving means 47, and the natural means adhered to the filling nozzle 7. Intestinal casing 2 The diameter of the natural intestinal casing 2 attached to the filling nozzle 7 is reduced to substantially eliminate the remaining shrinkage in the axial direction A, and the inner peripheral surface 31 of the natural intestinal casing 2 fills the nozzle. 7 is attached to the outer peripheral surface 3 almost completely.

 The air jet generating means 15 has an air nozzle 71 attached to the cover 40, and includes the air jetted from the air nozzle 71, including the position 11 Spraying near the position 11 prevents water droplets and the like adhering to the outer peripheral surface of the natural intestine casing 2 from scattering in the direction of the detecting means 13 by the rotation of the filling nozzle 7. are doing.

 The braking means 10, in particular the rotary braking members 22 and 23, ensure that the natural intestinal casing 2 is reduced in diameter by cooperation with the pulling means 14 and that the filling means Assists the transmission of rotation in the R direction from chiles 7 to natural intestinal casing 2.

During the filling of the raw material 4 into the natural intestinal casing 2, the natural intestinal casing 2 on the filling nozzle 7 is pulled by the pulling means 14 to the outer peripheral surface 3 of the filling nozzle 7. It moves toward the material discharge end 5 while making contact. The natural intestinal casing 2 in the contracted region 8 moves toward the non-rotationally-driven braking member 24 while pulling out the contraction in the axial direction A sequentially. Even if there is a natural intestine casing 2 whose contraction has not been completely removed, the natural intestinal casing 2 is stretched by passing through the non-rotating drive braking member 24, and the contraction is completely completed. Will be resolved. The length in the axial direction A of the region 8 becomes shorter as the raw material 4 is filled into the natural intestinal casing 2. The rear end 12 of the natural intestine casing 2 is pushed toward the raw material discharge end 5 automatically or manually by the intestinal pusher 21 as needed, and the contracted area 8 is left untouched. It is moved toward the rotary drive braking member 24.

 When the raw intestine casing 2 is sequentially filled with the raw material 4 and the rear end 12 of the natural intestinal casing 2 whose shrinkage has been eliminated passes through the position 11, the detector of the detection means 13 is Upon detecting this, the detecting means 13 emits a detection signal 48 indicating that the rear end 12 has passed the position 11. The raw material supply means 16 which receives this detection signal 48 from the detection means 13 immediately stops supplying the raw material 4 to the filling nozzle 7 and fills the natural intestinal casing 2 with the raw material. The operation is performed so as to prevent the raw material 4 from being discharged from the raw material discharge end 5 without being performed.

In the above description, the detection means 13 is provided after the natural intestinal casing 2 at the position 11 which is any position from the raw material discharge end 5 of the filling nozzle 7 to the rotary braking member 22. The passage of the end 12 is detected, but instead or in combination with this, the position 7 which is any position from the rotary braking member 23 to the non-rotary driving braking member 24 is used. In 5, a detecting means 13 a may be provided so as to detect the passage of the natural intestine casing 2 through the rear end 12. In this case, the air jet generating means 15a should also blow air near the position 75 including the position 75. It is good to provide.

 Further, as shown in FIG. 5, the apparatus 1 for manufacturing a sausage may be constituted by a braking means 10 having no non-rotating drive braking member 24. 3 fully stretches the natural intestinal casing 2 that has not been fully contracted in the axial direction A, similarly to the non-rotating drive braking member 24 in FIGS. 1 to 4. In this case as well, the passage of the rear end 12 of the natural intestinal casing 2 at any position from the raw material discharge end 5 of the filling nozzle 7 to the rotary braking member 22, for example, at the position 76, is detected. Alternatively, or in conjunction with this, any position from the rotary braking member 23 to the tip 9. For example, at position 77, the natural intestinal casing 2 The passage of the rear end 12 may be detected.

 In addition, as shown in FIG. 6, the sausage manufacturing apparatus 1 may be constituted by braking means 10 having no rotating braking members 22 and 23. In this case, the filling nozzle is also used. At any position from the raw material discharge end 5 of FIG. 7 to the non-rotating drive braking member 24, for example, at position 7 8, the passage of the natural intestinal casing 2 through the rear end 12 is detected. May be.

Further, as shown in FIG. 7, the sausage manufacturing apparatus 1 may be configured without the braking means 10. Also in this case, the passage of the rear end 12 of the natural intestinal casing 2 is detected at any position from the raw material discharge end 5 of the filling nozzle 7 to the front end 9 of the area 8. In the sausage manufacturing apparatus 1 shown in FIG. 7, as shown in FIG. 8, and as described in the specific examples of FIGS. 1 to 6, the natural intestine casing 2 is stretched, reduced in diameter, and filled. After moving on the nozzle 7, the rear end 12 is detected by the detection means 13.

 In the sausage manufacturing apparatus 1, the natural intestinal casing 2 is located at any position from the raw material discharge end 5 of the filling nozzle 7 to the tip 9 of the contracted region 8, and the natural intestine casing 2 is located in the axial direction A. In order to detect the passage of the rear end 12 of the natural intestine casing 2 moving toward the raw material discharge end 5 on the filling nozzle 7 at the extended position, the detection position and the raw material of the filling nozzle 7 are detected. When the distance between the discharge end 5 and the detected travel distance of the rear end 1 2 of the natural intestine casing 2 is equal, the time when the rear end 1 2 of the natural intestine casing 2 passes through the raw material discharge end 5 Thus, the supply stop timing of the raw material 4 to the filling nozzle 7 can be accurately synchronized.

 That is, in the sausage manufacturing apparatus 1, the rear end 12 has passed at least one of the positions 11, 75, 76, 77, 78, and 79. Since the supply of the raw material 4 is stopped based on the detection signal, the supply of the raw material 4 can be stopped accurately at the time when the rear end 12 reaches the raw material discharge end 5.

After the detection signal is output from the detection means 13, the supply of the raw material 4 to the filling nozzle 7 is stopped in accordance with the passage of the raw material discharge end 5 at the rear end 12. The time can be adjusted. As a result, the position where the filling of the raw material 4 with respect to the rear end 12 is completed can be adjusted. Instead of time adjustment, the position for detecting the rear end 12 may be adjusted in the axial direction A.

 Further, in the manufacturing apparatus 1, the natural intestine casing 2 contracted in the axial direction is stretched to form a natural intestine casing 2 having a uniform outer peripheral surface shape. Thus, the passage of the rear end 12 of the natural intestinal casing 2 is detected, so that the detection accuracy can be improved.
