In addition, in FIG. 2 and FIG. 3, 59 is a chute for collecting scraps of noodle skin.

Next, the method of use and operation of the baozi manufacturing apparatus configured as described above will be explained. As shown in FIG. They are placed on a noodle skin support stand 1 that moves intermittently on a moving path 3 and move together. When passing under the pressing roller 11, it is pressed by the roller 11 against the noodle peel cutter 10 on the noodle peel support stand 1, and the cutting blade 10a of the noodle peel cutter 10 makes a circular shape. Cut out into the noodle skin. The circular noodle skin 60 cut out as shown by the imaginary line in FIG.
The noodle skin 6 is supported on the noodle skin support stand 1 inside the noodle skin 0a.
The remaining noodle strip portion 9a from which 0 has been cut out is supported on the noodle skin support stand 1 outside the ring-shaped punching blade 10a and transported.

When the two noodle skin support stands 1 supporting the noodle skins 60 reach the predetermined positions directly below the topping filling means 4A, 4B and stop, as shown in FIG. 51 is lowered together with the filling piston 52. Of course, a predetermined amount of the ingredients in the ingredient hopper 8 is supplied into the lifting cylinder 51 from the ingredient extrusion passage 8a of the feeder shown in FIG. 8 to the lower position of the ingredient filling piston 52 via the ingredient receiving port 56. has been done.

By lowering the lifting cylinder 51, the noodle skin support base 1
As shown in FIG. 9, the upper noodle skin 60 has a center portion that is connected to the gear-shaped through hole 12 of the noodle skin support base 1 and the pleat twisting means 17A, 17 by the elevating cylinder 51.
The movable pieces 15a to 15 of the throttle means 5A and 5B are
It is pushed into the aperture hole 14 surrounded by d. At this time, the upper and lower gear-shaped through-holes 12 and 22 have matching concavities and convexities on the periphery as shown in FIG. The movable pieces 15a to 15d are at the starting end positions of their respective movement paths and are in the maximum state.

Note that when the lifting cylinder 51 pushes down the noodle skin 60, the lower end surface 51 of the lifting cylinder 51
The needle-like protrusion 53 protruding from a pierces the noodle skin 60 and prevents the noodle skin 60 from shifting in the lateral direction with respect to the lifting cylinder 51, so the lifting cylinder 51 reliably pushes down the center part of the noodle skin 60. I can do it.

As a result of the above-mentioned action, the noodle skin 60 is formed into a morning glory-like cup shape whose peripheral portion is folded into a gear shape by the upper and lower gear-shaped through holes 12 and 22. When the peripheral portion is in the gear-shaped through hole 22 in the rotating body 19 of the fold twisting means 17A, 17B as shown in FIG. It is rotated by a predetermined angle in a predetermined direction (counterclockwise in the illustrated example) by a cylinder unit 21 shown in FIG. As a result, as shown in FIG. 10, the protruding folds 60a around the noodle skin, which are fitted into the respective recesses around the gear-shaped through hole 22 of the rotary body 19, are folded in the direction of rotation of the rotary body 19. Become. That is, the noodle skin 60 is pushed down by the lifting cylinder 51.
is formed into a substantially cylindrical cup shape as shown in FIG. Of course, at this time, the noodle skin 60 is
If the protruding folds 60a are rotated together with
is stuck into the noodle skin 60 and prevents the noodle skin 60 from rotating with respect to the lifting cylinder 51, so that the protruding folds 60a can be reliably folded in the circumferential direction by the rotation of the rotating body 19. .

Once the noodle skins 60 are formed into a substantially cylindrical cup shape by the fold twisting means 17A and 17B as described above, the elevating cylinder 51 is further lowered to the lowering limit position, and the lower end of the elevating cylinder 51 is The covered noodle skin 60 is inserted into the hexagonal bao forming recess 35 of the bao receptacles 6A and 6B which are waiting at the upper limit position as shown in FIG. At this time, the cylindrical peripheral portion of the noodle skin 60 is squeezed by the squeezing means 5A, 5
It is located within the aperture hole 14 at B. When the elevating cylinder 51 reaches the lowering limit position, the elevating cylinder 51 is immediately moved upward.
By continuing to lower the internal ingredient filling piston 52, the ingredients 61 in the lifting cylinder 51 are moved by the ingredient filling piston 52 to the lifting cylinder 51.
It is pushed out from inside, inserted into the bao receivers 6A and 6B, and filled into the approximately cylindrical cup-shaped noodle wrapper 60 after the elevating cylinder 51 has been raised and removed. The filling piston 52 that has descended to the lower limit position is immediately moved upward. At this time, the filling piston 52
By supplying air inside and blowing it out from the air discharge port 54 opened at the lower end surface, it is possible to improve the separation between the lower end surface of the ingredient filling piston 52 and the ingredient 61.

When the toppings 61 are filled as described above, the topping-filled portion of the noodle skins 60 formed into a substantially cylindrical cup shape, that is, the lower half, fits into the bao-forming recesses 35 of the bao-bao receivers 6A and 6B. Therefore, the ingredients to be filled 6
The ingredient-filled portion of the noodle skin 60 that expands due to
It is prevented from unduly expanding and is molded to a substantially constant size.

When the filling of the ingredients 61 is completed, the ascending/lowering cylinder 51 and the ingredient filling piston 52 move to the throttle means 5A,
If it escapes upward from the aperture hole 14 of 5B,
By rotating the rotary ring 16 of the aperture means 5A, 5B and interlockingly moving each movable piece 15a to 15d in the aperture hole reduction direction, the position within the aperture hole 14 can be moved as shown in FIG. The peripheral portion of the opening of the noodle skin 60 is narrowed by the sides of the movable pieces 15a to 15d, and the narrowed portion is integrated and closed by the adhesive property of the noodle skin 60 itself.

Once the cylindrical peripheral portion of the noodle skin 60 has been squeezed by the squeezing means 5A, 5B to form the closed portion 60b as described above, before opening the squeezing hole 14 of the squeezing means 5A, 5B, the bao-receiving rotation drive means 36 (Figure 6). That is, the rack gear 39 is advanced and moved by the cylinder unit 40, and the baglet receiver 6A,
The cylindrical peripheral wall 23 of 6B is rotated by a predetermined angle.
The direction of rotation of this cylindrical peripheral wall 23 is determined by the twisting means 1
The direction of rotation of the rotating body 19 in 7A and 17B is the opposite direction, and in the illustrated example, it is clockwise. This rotation of the cylindrical peripheral wall 23 is caused by the rotation of the hexagonal peripheral wall inner surface 23a.
It is also transmitted to the pedestal 24 via the cylindrical peripheral wall 23
and the pedestal 24 rotate together.

By rotating the baglet receivers 6A and 6B, the closing part 60
b is the filling part of the noodle skin 60 held between the squeezing means 5A and 5B, that is, the bao receiver 6
The fitted portions of the envelope-forming recesses 35 of A and 6B are twisted relative to the closing portion 60b in a direction opposite to the folding direction of the protruding pleats 60a. As a result, as shown in FIG. 16, the folds 60a formed on the surface of the ingredient-filled portion so as to fall in the same direction are pulled in the circumferential direction and tightly adhere to the surface of the noodle skin, and are twisted in a spiral shape. It turns out. At this time, the inner surface 23 of the cylindrical peripheral wall 23 in the baglet receivers 6A and 6B
a has a hexagonal shape, and the surface of the ingredient-filled portion of the noodle skin 60 is in contact with this, so that when the cylindrical peripheral wall 23 rotates, the noodle skin 6 located inside the cylindrical peripheral wall 23
No slipping occurs between the ingredient-filled portion of the noodle skin 60 and the cylindrical peripheral wall 23, and the twisting action on the ingredient-filled portion of the noodle skin 60 is reliably performed.

By the above-mentioned twisting action, the formation of the folded wrapper 62 having the open folded part 60c above the closed part 60b as shown in FIG. 16 is completed, but after the twisting action is completed, the drawing means The rotating rings 16 of 5A and 5B are reversed, and the movable pieces 15a~
15d moves backward and the aperture hole 14 is opened. After this, the bao bag receivers 6A and 6B are moved by the driving means 25 (second
(Fig.). That is, the cylindrical peripheral wall 23 of the bao bag receivers 6A and 6B is lowered by the lifting drive rod 26 via the lifting drive table 27, the lifting rod 29, and the lifting table 30.
The downward movement of the cradle 7 is also transmitted to the cradle 24 via the spring 34 and the cradle drive rod 33, and the cylindrical peripheral wall 23 and the cradle 24 are lowered together. As shown in FIG. 14, when the pedestal 24 reaches the bao pushing level (the height of the guide plate 58),
The lower part of the pedestal 24 is received by the upper end 32a of the sleeve 32 which also serves as a stopper, and from then on, the spring 34 is only compressed as the elevating drive pedestal 27 descends, and the pedestal drive rod 33 does not descend. Therefore, only the cylindrical peripheral wall 23 continues to descend relative to the pedestal 24 which has stopped at the level of pushing out the bao.

As shown in FIG.
When they reach the same or slightly lower position, the lowering drive of the baglet receivers 6A and 6B by the lifting drive rod 26 ends. As a result, the cylindrical peripheral wall 23 is lowered below the pedestal 24, the bao-forming recesses 35 of the bao holders 6A and 6B are opened, and the folded bao 62 supported on the pedestal 24 is exposed on the pedestal 24. do. At this time, as shown in Fig. 14, the cutter 7
The cutting level by the blade plates 41 and 42 is around the boundary between the closed part 60b and the folded part 60c of the folded wrapper 62 on the holder 24. In this state, the cutter 7 is operated and the pair of upper and lower blade plates 41,
42, the closed part 60b and the folded part 60 of the folded wrapper 62 on the holder 24 are moved closer together.
The boundary with c is horizontally sheared between the deepest part of the U-shaped recessed blade edge 41a of the upper blade plate 41 and the linear blade edge 42a of the lower blade plate 42, as shown in FIG. Thus, the bao 63 with the mouth folds 60c cut and removed is completed.

Immediately after this fold part 60c is cut and removed, the arcuate pushers 50 of the bao pushing means 49A and 49B, which are moving together with the lower blade plate 42, come into contact with the side surface of the bao 63 on the holder 24. . Therefore, by continuing to drive the lower blade plate 42 even after cutting the folds, the arcuate pusher 50 causes the package 63 on the holder 24 to pass over the guide plate 58, as shown in FIG. The shaped bao can be pushed out onto the belt conveyor 57 for sending out the formed bao. On the other hand, the cut flap part 60c is blown away behind the cutter 7 by air discharged from the air blowing nozzle 64 as shown in FIG. 15, for example, and recovered by the chute 59 shown in FIGS. 2 and 3. I can do it.

It should be noted that the reverse return of the bao holders 6A and 6B, which have been rotated by a certain angle in order to twist the filling part with respect to the closing part 60b, ie, the cylinder unit 4 shown in FIG.
The backward movement of the rack gear 39 by 0 may be carried out at an appropriate time after opening the throttle holes 14 of the throttle means 5A, 5B, except when the cutter 7 is cutting.

Note that the cutter 7 shown in the above embodiment is not essential to the apparatus of the present invention. That is, even without the cutter 7, it is possible to manufacture the folded bao 62 as shown in FIG. Also, baoshi receivers 6A, 6B
The cylindrical peripheral wall 23 is also not essential to the device of the present invention. Therefore, the rotation driving means 3 for the baglet receivers 6A and 6B
6 is also not essential to the device of the present invention and can be omitted.

(Operations and Effects of the Invention) According to the baguette manufacturing apparatus of the present invention which can be implemented as described above, the peripheral portion of the baguette wrapper pushed down from the baguette wrapper support base by the lifting cylinder of the filling means is When the rotating body of the fold twisting means is located in the gear-shaped through hole, the pushing down action is interrupted and the rotating body of the fold twisting means is rotated, so that the peripheral portion is inserted into the gear-shaped through hole. The protruding folds of the wrapper skin formed by entering each recess around the hole can be folded in the same direction. That is, not only can pleats be neatly formed around the wrapper skin formed into a cup shape, but also the folds can be folded in the same direction and overlapped on the surface of the wrapper.
Therefore, when this cup-shaped shell is pushed down onto the bao holder by the elevating cylinder of the ingredient filling means and filled with ingredients, when the area around the opening of the shell is squeezed by the squeezing means, the folds are not formed as in the conventional case. The baozi will not be crushed irregularly and become unduly bulky, and the baozi will have a pleasant texture when eaten. Moreover, since a needle-like protrusion is provided on the lower end surface of the elevating cylinder, the wrapper skin pushed down by the elevating cylinder is pierced by the needle-like protrusion and is held unrotatable. When the rotary body of the fold twisting means is rotated, there is no risk that the skin body and the rotary body will rotate together, and the protruding fold portion can be folded reliably. Since these pleats are neatly folded in the same direction, it is possible to supply the product to the market as a baguette with high commercial value.
