Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applicable to various wrapped foods such as shumai, meat buns, and bean paste buns, i.e., baozi (baosi) in which ingredients are wrapped in an edible skin such as noodle skin. This relates to manufacturing equipment for Paoz.

(Prior art and its problems) This type of baguage manufacturing apparatus forms a baguette wrapper cut into a predetermined shape such as a circle into a cup shape, fills the inside with fillings, and It is designed to mechanically perform a series of actions to squeeze and close the area around the opening of the body, but in conventional packaging manufacturing equipment of this type, the area around the opening of the bag-shaped bag body is squeezed and closed. Since the mouth was simply closed by squeezing, a fold of the mouth was left that spread above the closed area formed by the squeezing. These mouth folds may make the bao taste unpleasant when eaten, so there is a demand for bao that does not leave such mouth folds. Of course, even in the conventional device, if the aperture level is adjusted by the aperture means and the area around the opening of the cup-shaped wrapper is constricted as close to the upper end as possible, large opening folds can be avoided. However, when the wrapper for cup-shaped bao expands due to the ingredients being filled, the periphery of the wrapper is pulled downward and removed from the aperture of the squeezing means, resulting in a squeezing effect. There is a risk that you will not be able to do it.

(Means for Solving the Problems) The present invention proposes a baguette manufacturing apparatus capable of solving the conventional problems as described above, and its feature is that the baguette wrapper has a through hole in the center. a body support stand, a liftable bao holder provided on the underside of the bao cover support; a center part of the bao cover on the bao cover support stand is inserted through the through hole into the bao holder; A filling means that can be raised and lowered to push down to the top to form a cup shape and fill the filling inside the baglet wrapper, and a squeezing device that squeezes and closes the opening periphery of the cup-shaped baglet cover on the baglet holder. and a cutter for cutting the squeezed and closed portion of the bao on the holder or a position near the same when the holder is lowered to a predetermined position.

In Figures 2 and 3, 63
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, the roller 11 presses the noodle peel cutter 10 on the noodle peel support 1, and the noodle peel cutter 10's cutting blade 10a creates a circular shape. Cut out into the noodle skin. The circular noodle skin 64 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 4 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 64 reach the predetermined positions directly below the topping filling means 4A, 4B and stop, as shown in FIG. 57 is lowered together with the filling piston 58. Of course, in this elevating cylinder 57, a predetermined amount of the ingredients in the ingredient hopper 8 are supplied to the lower position of the ingredient filling piston 58 from the ingredient extrusion passage 8a of the feeder shown in FIG. has been done.

By lowering the lifting cylinder 57, the noodle skin support base 1
As shown in FIG. 9, the upper noodle skin 64 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 57.
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 18 have matching concavities and convexities on their peripheries 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.

As a result of the above-mentioned action, the noodle skin 64 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 18. When the peripheral portion is located within the gear-shaped through hole 18 in the rotating body 19 of the fold twisting means 17A, 17B as shown in FIG. (counterclockwise in the illustrated example) by a predetermined angle, and as shown in FIG. The portion 64a is folded in the direction of rotation of the rotating body 19. That is, the lifting cylinder 5
The noodle skin 64 pushed down by the noodle 7 is formed into a substantially cylindrical cup shape as shown in FIG.

Once the noodle skins 64 have been formed into a substantially cylindrical cup shape by the fold twisting means 17A and 17B as described above, the elevating cylinder 57 is further lowered to the lowering limit position, and the lower end of the elevating cylinder 57 is The covered noodle wrappers 64 are held in the bao-forming cups 6A and 6B waiting at the upper limit position as shown in FIG.
Insert into the hexagonal envelope forming recess 32 in the box. At this time, the cylindrical peripheral portion of the noodle skin 64 is located within the throttle hole 14 in the throttle means 5A, 5B. When the elevating cylinder 57 reaches the lower limit position, the elevating cylinder 57 is immediately moved upward, but the ingredient filling piston 58 inside continues to descend further, so that the ingredients 65 in the elevating cylinder 57 move up to the ingredient filling piston 58. The cup 6 is pushed out from inside the lifting cylinder 57 by the
A, 6B, and is filled into the approximately cylindrical cup-shaped noodle skin 64 after the lifting cylinder 57 rises and escapes. The ingredient filling piston 58 that has descended to the lower limit position is immediately moved upward.

When the filling of the ingredients 65 is completed, the ascending/lowering cylinder 57 and the ingredient filling piston 58 move to the throttle means 5A,
If it escapes upward from the aperture hole 14 of 5B,
The rotary rings 16 of the aperture means 5A, 5B are rotated in the same direction by a predetermined angle to move each movable piece 15a to 15d in the aperture hole reduction direction. As a result, the 13th
As shown in the figure, the cylindrical peripheral portion of the noodle skin 64 located within the aperture hole 14 is connected to the movable pieces 15a to 15.
The noodle skin 64 itself is squeezed by the side edges d, and the squeezed portion is integrated and closed by the adhesive property of the noodle skin 64 itself.

Once the cylindrical peripheral portion of the noodle skin 64 has been squeezed by the squeezing means 5A, 5B to form the closed portion 64b as described above, before opening the aperture hole 14 of the squeezing means 5A, 5B, the cup rotation drive means 33 (FIG. 2) to rotate the cylindrical peripheral walls 20 of the envelope-forming cups 6A, 6B by a predetermined angle via the cylindrical rotating body 34. The direction of rotation of this cylindrical peripheral wall 20 is opposite to the direction of rotation of the rotating body 19 in the fold twisting means 17A, 17B, and is clockwise in the illustrated example. This rotation of the cylindrical peripheral wall 20 is also transmitted to the pedestal 21 via the hexagonal inner surface 20a of the peripheral wall, and the cylindrical peripheral wall 20 and the pedestal 21 rotate together.

Due to the rotation of the bao-forming cups 6A, 6B, the closing portion 64b is fitted into the filling-filled portion of the noodle skin 64 held by the squeezing means 5A, 5B, that is, the bao-forming recess 32 of the bao-forming cups 6A, 6B. The matching portion is twisted relative to the closing portion 64b in a direction opposite to the folding direction of the protruding fold portion 64a. As a result, as shown in FIG. 16, the folds 64a formed on the surface of the ingredient-filled portion so as to fall in the same direction are twisted spirally.

By the above-mentioned twisting action, the formation of the folded wrapper 66 having the open folded part 64c above the closed part 64b as shown in FIG. 16 is completed, but after the twisting action is completed, the drawing means Reverse the rotation rings 16 of 5A and 5B, and move the movable pieces 15a to 15d.
is moved backward to open the aperture hole 14. After that, the bao-forming cups 6A, 6B are moved to the driving means 22.
(Fig. 2). That is, the lifting drive rod 23 moves the lifting drive platform 24 and the lifting rod 2.
5, and the bao-forming cup 6 via the lifting platform 27.
The cylindrical peripheral walls 20 of A and 6B are lowered, but at this time, the downward movement of the lifting drive platform 24 is also transmitted to the pedestal 21 via the spring 31 and the pedestal drive rod 30, and the cylindrical peripheral wall 20 and the pedestal 21 are lowered. and descend as one. Then, as shown in FIG.
1 reaches the bao pushing out level (the height of the guide plate 62), the lower part of the holder 21 is received by the upper end 29a of the sleeve 29 which also serves as a stopper, and from this point on, as the elevating drive platform 24 descends, the spring 31 is compressed, but the pedestal drive rod 30 does not descend. Therefore, only the cylindrical peripheral wall 20 continues to descend relative to the pedestal 21 which has stopped at the level of extruding the bao.

As shown in FIG. 14, the upper end of the descending cylindrical peripheral wall 20 is at the baozi extrusion level (the height of the guide plate 62).
When the cup reaches the same or slightly lower position, the lifting drive rod 23 lifts the envelope-forming cups 6A, 6B.
The downward drive of is completed. As a result, the cylindrical peripheral wall 20
is lower than the pedestal 21, and the bao-forming cup 6
The bao-forming recesses 32 of A and 6B are opened, and the folded bao 66 supported on the pedestal 21 is exposed on the pedestal 21. At this time, as shown in FIG. 14, the cutting level by the blade plates 41, 42 of the cutter 7 is around the boundary between the closed part 64b and the folded part 64c of the folded wrap 66 on the holder 21. In this state, the cutter 7 is operated.

That is, the pair of push-pull drive rods 46 shown in FIG. 6 move the upper blade plate 41 forward via both swing levers 45, pins 45a, and long holes 41b, and the push-pull drive rods 47 move the drive bar 48 forward. and move the lower blade plate 42 in the opposite direction via the portal member 49. As a result, the closed part 64b and the folded part 64c of the folded bao 66 on the holder 21
The boundary between the deepest part of the U-shaped recessed blade edge 41a of the upper blade plate 41 and the linear blade edge 4 of the lower blade plate 42
2a, and a bao 67 is completed with the mouth folds 64c cut and removed, as shown in FIG. 17.

Immediately after the fold part 64c is cut and removed, the arcuate pushers 54 of the bao pushing means 53A and 53B, which are moving together with the lower blade plate 42, come into contact with the side surface of the bao 67 on the holder 21. . Therefore, by continuing to drive the lower blade plate 42 even after cutting the folds, the arcuate pusher 54 allows the package 67 on the receiving stand 21 to pass over the guide plate 62, as shown in FIG. It is possible to extrude the formed baglet onto a belt conveyor 61 for sending it out. On the other hand, the cut crease 64c is blown away behind the cutter 7 by air discharged from an air blowing nozzle 68 as shown in FIG. 15, for example, and recovered by the chute 63 shown in FIGS. 2 and 3. I can do it.

In addition, the bao-formed cups 6A, 6 are rotated at a certain angle in order to twist the filling part with respect to the closing part 64b.
The reverse return of B is performed through the throttle holes 1 of the throttle means 5A and 5B.
This may be done at an appropriate time after the opening of the cutter 4, except when the cutter 7 is cutting.

The cutting level by the cutter 7 can be adjusted up and down as explained above, but this cutting level can be adjusted by adjusting the cutting level by the cradle 21 as shown by the imaginary line in FIG.
By making it lower than the closing part 64b of the upper folded bao 66, the noodle skin 6 is lower than the closing part 64b of the upper folded bao 66.
4 can be cut horizontally, it is also possible to manufacture a special shaped bao 69 having an opening 64d through which the tool 65 can be seen, as shown in FIG.

Incidentally, the fold twisting device 17 and the rotational drive means 33 for the bao-forming cup shown in the above embodiments are not essential to the apparatus of the present invention and can be omitted. Further, in the embodiment, the cylindrical peripheral wall 20 is combined with the cylindrical bag holder 21 to form the bag 6A, 6B, but the cylindrical peripheral wall 20 is not essential to the blade and may be omitted.

(Operations and Effects of the Invention) According to the baozi manufacturing apparatus of the present invention which can be carried out as described above, the periphery of the opening of the bao wrapper (noodle wrapper 64 in the embodiment) formed into a cup shape and filled with ingredients. In addition to squeezing and closing the portion using a squeezing means, the mouth folds remaining above the squeezed closed portion can be cut and removed using a cutter, so that there is no extra mouth fold that makes the mouthfeel unpleasant when eating. It is possible to produce baozi without Moreover, since the squeezing position of the squeezing means can be appropriately lowered from the upper end of the area around the opening of the skin, there is no problem of the skin coming off from the squeezing means, and the squeezing action can always be performed reliably. obtain.

Further, since the cutting action by the cutter is performed with the baglet holder in a lowered state, there is no need to forcefully install the cutter and its driving mechanism in a very narrow space above the squeezing means. In other words, the position of the squeezing means and the upper limit position of the bao holder are determined by adjusting the position of the bao wrapper supporter (noodle wrapper supporter 1 in the embodiment).
It is possible to reduce the stroke of pushing down the skin by the ingredient filling means.
