Description

  TECHNICAL FIELD The present invention relates to a food dough forming machine that flattens and forms food dough such as pizza from a lump state, and more specifically, a food dough forming machine that has a function of pulverizing dust to food dough during spreading. About.

  2. Description of the Related Art Conventionally, there is known a food dough forming machine that spreads food dough gathered into a nodule shape after the kneading operation is finished. The food dough forming machine includes a dish body on which the food dough is placed, a roller support frame body that can be raised and lowered with respect to the dish body above the dish body, and a roller support frame body that can be horizontally rotated. And a plurality of conical rollers arranged radially with their tips close to each other. In this food dough forming machine, when the roller support frame rotates horizontally around a vertical axis, the plurality of conical rollers are rotated while revolving on the upper surface of the food dough, so that the food dough has a thin and uniform thickness. It extends in a circular shape (see, for example, Patent Document 1).

On the other hand, a technique for dusting food materials has also been proposed. As an example, powder supply means for dropping the powder contained in the hopper from the bottom of the hopper, and the powder dropped from the powder supply means on the surface of the food material moved on the conveyor by the rotational movement of the dusting brush The dusting means for wiping off and adhering to the surface of the food material, and the powder brush provided below the dusting means in contact with the dusting brush and returning the powder not adhering to the food material to the dusting brush. There is a powder circulation type powdering machine including a powder returning means to be re-supplied to (see, for example, Patent Document 2).
JP 2007-174953 A JP-A-11-243836

  A food dough forming machine such as Patent Document 1 is mainly used to spread food materials such as pizza dough and stretch cake into a thin circular shape. Generally, a powdered food material is hydrated and kneaded into a nodule. When spreading thinly all together, the food dough sticks to the roller and the food dough is torn, the food dough surface is uneven, or the forming operation needs to be interrupted in order to peel the stuck food dough from the roller.

The sticking of such food dough varies depending on the temperature, humidity, and amount of water at that time. It is required to prevent sticking between each other.
However, with the food dough forming machine disclosed in Patent Document 1, it has been difficult to apply an appropriate amount of dust to the food material during spreading. The reason for this is that the frame that supports the rollers at the top of the roller during the extension work is rotating, making it a hindrance to shake the dust over the entire food dough. Since the plurality of rollers are rotating in contact with each other on the top of the machine, it is impossible to uniformly dust the food dough, and when the rollers and the roller support frame are moved upward from the food dough, Due to the compact size, the space between the food dough and the roller is very small, and it may be difficult to apply dust to the entire food dough.

  Moreover, patent document 2 is related with the technique regarding the exclusive powdering machine which only shakes a dust to food material. Therefore, when forming food dough, both a food dough forming machine such as Patent Document 1 and a powdering machine disclosed in Patent Document 2 must be prepared. Since the dough forming operation and the dusting operation are separately performed, workability is extremely poor.

  The present invention has been made in the background of such a situation, and the object of the present invention is to efficiently perform dusting when spreading food dough without greatly changing the structure or increasing the size of the apparatus. An object of the present invention is to provide a food dough forming machine that can be shaken and can effectively prevent sticking of food dough.

In order to achieve the above-described object, the food dough forming machine of the present invention includes a dish body on which food dough is placed, and a roller support that is provided above the dish body so as to be movable up and down and horizontally rotatable with respect to the dish body. A plurality of frames and radially arranged so that the front ends thereof are close to each other below the roller support frame, and are rotated while revolving around the vertical axis of the roller support frame to uniformly extend the food dough In the food dough forming machine provided with a cone-shaped roller, a dust receiving tray is detachably disposed between the roller support frame and the cone-shaped roller, and the accommodated dust is stored in the dust receiving tray. A dust discharge hole to be supplied to each of the rollers was formed.
As long as the dust receiving portion is formed between adjacent rollers, the dust receiving tray may be disposed in an integral configuration between the roller support frame and the conical roller, or adjacent rollers. You may arrange | position each independently in between.
Further, the discharge holes can have any shape and any number. For example, a rectangular shape, a circular shape, or a plurality of triangular shapes can be arranged. The position of the discharge hole is preferably provided near the large diameter portion of the roller so that the dust reaches the tip of the roller using the inclined surface of the roller.

Moreover, in the food dough forming machine, the dust receiving tray has a plurality of tapered ridges having a circular cross-section extending radially outward from the central portion thereof, and a valley-like shape interposed between the ridge portions. The dust-contained portions are alternately arranged in the circumferential direction, and the conical rollers are loosely fitted in the back-side concave portions of the tapered ridges having an arcuate cross section, and adjacent to the dust-contained portions. It can be set as the structure which drilled the said dust discharge hole in the side wall of the said protrusion circular arc shaped cross section.
In the dust receiving portion, the side wall of each taper-shaped protruding portion, and the slope of the mountain-shaped protruding portion that makes it easy to flow the dust into the discharge hole by making the entire space a dust receiving portion by a plate connecting them Surfaces can be formed, partitioned and box-shaped, or funnel-shaped.

Further, in the invention of the food dough forming machine, an inverted frustoconical roller driving plate is rotatably disposed above the dust receiving tray, and the tapered outer peripheral surface on the lower surface side of the roller driving plate is the tapered protrusion. The rollers are rotated by the rotational drive of the roller drive board by being pressed against the outer peripheral surface of the rollers via a power transmission port formed on the upper surface of the section.
A friction body can be attached to the tapered outer peripheral surface so that the friction is increased and the rotation of the roller driving plate is sufficiently transmitted. For example, it is a ring-shaped rubber body. In addition, a protrusion can be formed on the tapered outer peripheral surface, or a resin sheet can be attached. Moreover, the shape of the power transmission port can be an arbitrary shape such as a rectangular shape according to the configuration of the tapered surface as described above.

In the food dough forming machine according to the present invention, the roller support frame is provided with an inlet for feeding dust onto the dust receiving tray.
The shape and size of the inlet can be arbitrarily determined. It may be round or square. The number of input ports may correspond to the number of dusting accommodating portions, but may be formed in one place and distributed to each accommodating portion.

Furthermore, in the invention of the food dough forming machine, a concave powder storage part for temporarily storing the powder is formed on the outer peripheral surface of the conical roller.
As the concave powder storage part, a spiral or ring-shaped groove can be provided, a large number of dimples can be formed, or a large number of radial grooves can be provided from the tip of the roller to the large diameter part.

  According to the first aspect of the present invention, a dust receiving tray is detachably disposed between the roller support frame and the conical roller, and the dust accommodated in the dust receiving tray is disposed on each of the rollers. Since the powder discharge hole to be supplied is formed, a compact food dough forming machine provided with a powder storage portion can be provided. Further, the dust is attached to the outer periphery of the conical roller from the dust discharge hole, and the rotation of the roller spreads the dust to the tip of the roller. Thus, even when the food dough is extended, even if there is no space between the food dough and the roller, the dust can be uniformly applied to the food dough. And since the operation | work which shakes this dust is performed simultaneously with the spreading | diffusion of food dough, the apparatus which shakes dust separately from a food dough forming machine, and the dust work by manual work are not required. Moreover, the maintenance can be easily performed by removing the dust receiving tray. Thereby, an equipment burden and an economic burden can be reduced, and work efficiency can be improved.

  According to the invention described in claim 2, the dust receiving tray has a plurality of tapered ridges having a cross-sectional arc shape radially extending outward from the central portion thereof, and a valley-like shape interposed between the ridge portions. The dust-contained portions are alternately arranged in the circumferential direction, and the conical rollers are loosely fitted in the back-side concave portions of the tapered ridges having an arcuate cross section, and adjacent to the dust-contained portions. Since the dust discharge hole is drilled in the side wall of the projecting arch portion having an arcuate cross section, a single dust receiving tray is provided between the roller support frame and the conical roller, and the number of parts is reduced. In addition to being more compact, it is easy to attach and detach the dust receiving tray, so that the manufacturing efficiency is improved and the maintainability is further improved.

  According to the third aspect of the present invention, each of the rollers rotates at the same speed by the rotational movement of the roller drive board above the dust receiving tray. For this reason, some rollers do not stop rotating or slow down. As a result, the food dough is not broken and the food dough can be stretched uniformly. In addition, since the roller drive board can be installed directly below the roller support frame and in the space above each roller, the food molding machine can be made compact.

  According to the fourth aspect of the present invention, since the charging port is formed in the roller support frame body, the operation of charging the dust is facilitated, and the working efficiency can be increased.

  According to the invention described in claim 5, the concave powder storage portion in which the powder is temporarily stored is formed on the outer peripheral surface of the conical roller, so that the conical roller is changed from the powder discharge hole. Since the dust that has been supplied and temporarily adheres to the outer peripheral surface of the roller temporarily remains in the dust storage part without immediately falling, the powder stored in the powder storage part with the rotation of the roller is uniform over the entire surface of the food dough. The dusting can be reliably shaken.

As described above, the double structure of the inner shaft 19b and the outer shaft 19a is configured to transmit different power from the drive motor 45 to each shaft.
The double-structured inner and outer shafts 19b and 19a are pivotally supported by an interlocking case 36 that casings the upper portion of the drive unit 9a, and are provided on an elevating device 70 including an elevator frame 35 provided on the side of the interlocking case 36. It is interlocked and connected to the pressing portion 8 so as to be movable up and down.

Further, as shown in FIGS. 1, 3, and 4, a roller support frame 16 is connected to the lower end of the outer shaft 19a.
The roller support frame 16 is formed in a substantially rectangular plate shape, has flange portions projecting downward on the four side portions, and has formed inlets 40 for the dust N at the four corners. The roller bearing plate 17 having a substantially inverted triangular shape is screwed to each other.

  As shown in FIGS. 4 and 5, the roller bearing plate 17 is formed with U-shaped notches near the upper corners, and is formed on the flange of the roller support frame 16 with the screw 23 with a grip through the notches. It is screwed into the screw hole and attached in a downwardly expanding manner. Each roller bearing plate 17 is configured to support the roller 7 in a cantilever manner, and the roller 7 is supported by a roller shaft 24 extending in a direction perpendicular to the roller bearing plate 17.

That is, the output shaft 65 of the rotary motor 57 is in a suspended state, and the output shaft 65 is configured to be spline-fitted with the inside of the cylindrical rotary shaft 62. 65 is detachable from the rotary shaft 62.

  Next, operation | movement description of the food dough forming machine 1 in the case of shape | molding from a lump-like food dough to a flat food dough is performed.

  First, the front lid 2 is opened upward, and the dust N is charged into the dust receiving tray 18 from the inlet 40 formed at the four corners of the roller support frame 16. The amount of dust N is such that the dust discharge hole 28 is hidden as a minimum amount, and an operator manually supplies the dust to the dust inlet 40 and replenishes it. If a certain amount of dust N is accommodated, opening and closing of the front lid is unnecessary. The dish holding table 13 is pulled out from the dough forming unit 4 and the dish 5 is dusted. The prepared block-shaped food dough M is placed in the center of the dish body 5. The positioning of the dish body 5 and the dish body holding table 13 is performed by engaging the held portion 51 on the bottom surface of the dish body 5 with the receiving plate 52 on the dish body holding table 13.

  Next, the tray holding table 13 is slid into the dough forming portion 4 and set so that the pressing portion 8 supporting the roller 7 and the like is positioned on the concentric axis of the tray 5, and then an operation (not shown) Turn on the switch. When the operation switch is turned on, the pressing unit 8 is lowered by the lifting device 70 having the lifting machine frame 35. In addition, it can also be set as the structure which senses that the tray holding | maintenance table 13 was slid and was inserted and an operation switch turns on automatically and the press part 8 descend | falls.

  When the roller 7 of the pressing unit 8 comes into contact with the massive food dough M, the drive motor 45 of the drive unit 9a is started by the action of a sensor (not shown) that detects the load. The driving force of the drive motor 45 is transmitted to the upper and lower passive gears 48b and 48a via the upper and lower drive gears 47b and 47a provided above and below the output shaft 46. The driving motor 45 may be started by detecting that the pressing portion 8 has been lowered to a certain height.

  The driving force of the driving motor 45 transmitted to the lower passive gear 48a rotates the outer shaft 19a connected to the lower passive gear 48a. Thereby, the press part 8 rotates horizontally. That is, the roller support frame body 16 connected to the outer shaft 19a rotates horizontally, and at the same time, each roller 7 which is loosely fitted to the roller bearing plate 17 screwed to the roller support frame body 16 and whose tip is close to the roller support frame body 16 Revolves around the tip. Naturally, the dust receiving tray 18 disposed between the roller support frame 16 and each roller and connected by the outflow prevention plate 41 also rotates.

  On the other hand, the driving force of the driving motor 45 transmitted to the upper passive gear 48b rotates the inner shaft 19b connected to the upper passive gear 48b. As a result, the roller drive board 20 connected to the inner shaft 19b rotates horizontally. When the roller drive board 20 rotates, the outer circumference of each of the conical rollers 7 through the tapered outer peripheral surface of the roller drive board 20 and the power transmission port formed in the ring-shaped friction body 31 in the tapered protrusion 27. The upper part of the surface is pressed and the driving force is transmitted to each roller 7 as if it is a bevel gear, so that each roller 7 rotates.

  At the time of the extension work, the powder dough N is supplied so that the food dough M adheres to each roller 7 and does not interfere with the extension work. According to this embodiment, the powder receiving portion of the powder receiving tray 18 is provided. The dust N accommodated in 42 is drawn from the dust discharge hole 28 by the rotation of each roller 7 and is automatically supplied to the outer peripheral surface of each roller 7.

  The dust N supplied from the discharge hole 28 covers the entire outer peripheral surface of each roller 7 while sliding down to the tip by the tapered surface of the roller 7, and the dust N is uniformly distributed on the food dough M. Note that the supply amount of the dust N is an appropriate supply amount in advance by providing an adjustment plate 43 (see FIG. 7) that can adjust the distance between the dust discharge hole 28 and the roller 7 at the lower portion of the dust discharge hole 28. The interval is adjusted as described above.

Further, in the present embodiment, in the initial stage of the extension work, the pressing portion 8 is moved up and down a plurality of times, and each time it descends, the rotation / revolution is controlled to rotate in the reverse direction. Then, at the final stage of the work where the food dough M becomes a certain thickness due to the extending work, the rotary motor 57 of the drive unit 9b that is on the lower rear side inside the machine frame 3 and moves up and down together with the pressing unit 8 is the rotary shaft 62. So that the power of the rotary motor 57 is transmitted to the drive pulley 61, and the power is transmitted to the passive pulley 59 and the rotary shaft 58 suspended from the center lower surface of the plate body 5 by the interlock belt 60. Is done.
As a result, the plate body 5 rotates in the same direction as the roller support frame body 16, and the finishing operation is performed so that the spread dough or the like does not come to the food dough M. In addition, it is desirable that the rotational speed of the plate 5 at this time is slower than or equal to the rotational speed of the roller support frame 16.

  When the food dough M has a desired thickness and the extension is finished, the pressing portion 8 rises and stops rotating and stops at the upper limit.

  Thereafter, when the dish holding table 13 is pulled forward from the dough forming unit 4 and the dish body 5 is removed and turned upside down, a desired food dough having a flat shape and an edge formed on the outer periphery is obtained.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.

  For example, as a modified example of the roller 7, as shown in FIG. 8, a spiral groove storing portion 44 having a spiral groove can be formed on the outer peripheral surface of the roller 7. The dust storage section 44 does not immediately drop the dust N from the dust discharge hole 28 or the outer peripheral surface of the roller 7, but temporarily reaches the tip of the roller 7 while being temporarily stored on the outer peripheral surface of the roller 7. It is possible to shake the dust N evenly and evenly with respect to the food dough M.

  That is, with the structure in which the spiral groove storing portion 44 is formed on the outer peripheral surface of the roller 7, the dust N adhering to the roller 7 and moving upward from the position of the discharge hole 28 is moved to the tip by the tapered surface of the roller 7. A part of the roller 7 is stored in spiral grooves formed on the outer peripheral surface of the roller 7 while sliding down, and covers the outer peripheral surface of each roller 7.
