Description

[Detailed description of the invention] (Industrial application field) The present invention is applicable to the deep-frying process and baking process when producing various types of foods with cores, in which different ingredients are wrapped in a viscous material generally called nerimono. This relates to a molding machine that continuously molds a material before it is subjected to processing.

(Prior art and its problems) Conventionally, when producing fried foods with core ingredients, such as fish cakes with quail eggs or burdock tempura, a viscous material made by mixing ground fish and flour, etc. into a paste was used, which was boiled. It was common practice to wrap core ingredients such as quail eggs and burdock by hand and feed this into an automatic deep-frying machine to make it into a product.

For this reason, conventional fried foods with a core require a lot of labor and time to manufacture, making mass production difficult, resulting in high costs and problems in that the size and shape of the products are not consistent.

(Means for Solving the Problems) The present invention proposes a continuous molding machine for core-containing foods that can solve the conventional problems as described above, and its features include an upper horizontal conveyance path and a plurality of molding cups that rotate in a row along a circulation path consisting of a lower return path; a molding bar that is rotatable within the molding recess of each of the molding cups along the inner bottom surface having an arcuate longitudinal section; a forming bar rotation device that rotates the forming bar in the middle of the upper horizontal conveyance path below the supply position of the viscous material and core to the forming recess of each forming cup; a molded product discharge part provided at a starting end, and a first cam driven part and a second cam driven part are provided at an eccentric position with a phase shifted by 90 degrees from each other on the driving rotation shaft of the molding bar. , a first fixed cam located on the side of the path above the supply position of the viscous material and the core, the first fixed cam acting on the first cam driven part to position the second cam driven part in the latter half region with respect to the rotating shaft; and a second fixed cam for positioning the second cam driven part at a rear position of the rotating shaft, and when the second cam driven part is at the rear position of the rotating shaft, the molding bar is This is because it is configured to be located at the deepest position of the molded recess.

As shown in FIGS. 2 to 5, the molded cup 7 includes two circular molded recesses 15 arranged in parallel in the horizontal width direction perpendicular to the moving direction, and both ends in the width direction are formed by a pair of left and right molded recesses 15. They are connected to the roller chain 6 via brackets 6a, respectively. The molded recess 15 has a spherical inner bottom surface 15a whose longitudinal side surface is arcuate, and this spherical inner bottom surface 15a
A slit 16 is formed across the entire width of the molded cup 7 so as to cross the center of the cylindrical upper half 15b. 17 is each molded recess 15
It is an arc-shaped forming bar that is loosely fitted into the slit 16, and is constituted by a crank portion of a rotating shaft 18 that is loosely fitted into the slit 16, and the spherical inner bottom surface 15a is formed by rotation of the rotating shaft 18. It can be rotated by sliding in contact with. At this time, the depth of the molding recess 15 is determined so that the molding bar 17 partially protrudes from the molding recess 15 and rotates. 19 is a plate spring for holding down the rotating shaft, and a molded cup 7
The rotating shaft 18, which is attached to the lower side of the bracket 20 attached to both ends of the molded cup 7 and protrudes from both ends of the molded cup 7, is pressed toward the bottom side of the slit 16. Reference numeral 21 denotes an auxiliary arm fixed to one end of the rotating shaft 18, and a first cam follower (preferably a roller) 22 is protruded from an eccentric position on the outer surface of the auxiliary arm. 23 is a passive gear fixed to the other end of the rotating shaft 18, and a second cam follower (preferably a roller) 2 is provided at an eccentric position on the outer surface of the gear.
4 is provided protrudingly. However, as shown in FIG. 11A, when the molding bar 17 is located directly above the molding recess 15, the first cam driven part 22 is located directly below the rotating shaft 18, and the second cam driven part 22 is located directly below the rotating shaft 18. Part 24
is located at a position shifted forward by 90 degrees from the first cam follower 22, that is, in front of the rotating shaft 18 (on the side in the direction of movement of the molded cup 7). Note that 25 is a chain guide rail that rotatably supports the pair of left and right roller chains 6.

The molding bar rotating device 10 is composed of a low speed rotation means 26 and a high speed rotation means 27, as shown in FIGS. 6 and 7. Low speed rotation means 2
Reference numeral 6 refers to a roller chain 29 of a predetermined length fitted onto a fixed support bar 28 which is height-adjustably disposed along the lower side of the moving path of the gear 23. The high speed rotation means 27 disposed on the lower side of the means 26 and along the lower side of the movement path of the tooth wheel 23 rotates the driving tooth wheel 30 and the free rotation tooth wheel 3.
1 is provided with an endless roller chain 32 suspended between the roller chain 1 and the roller chain 32. The supporting member 33 that pivotally supports the free rotating toothed wheel 31 is vertically swingably supported on a drive shaft 34 to which the driving toothed wheel 30 is fixed, and is supported by a hanging bolt 35.
It is fixed in an adjustable angle. Reference numeral 36 denotes a chain guide rail, which is attached to the support member 33. Although the roller chain 29 is used as the low-speed rotation means 26, a rack gear or something similar thereto may also be used depending on the shape of the teeth of the gear 21.

As shown in FIGS. 6 to 8, the material holding belt device 11 includes an endless belt 39 stretched between a drive roller 37 and an idle roller 38;
A plurality of pressing rollers 40 are provided to support the material pressing path portion 39a in contact with the surface of the molding cup 7 so as to be pushed up by the molding bar 17 which protrudes from the molding recess 15 and rotates. A drive shaft 41 to which the drive roller 37 is fixed, and a rotation shaft 42 to which the idle roller 38 is fixed.
Both are supported in a cantilevered manner via bearings 43 and 44.

At the starting end of the upper horizontal conveyance path 2 in the circulation transfer device 1, as shown in FIGS. The fixed cam 45 and the second fixed cam 46 acting on the second cam driven part 24 are arranged so that the second fixed cam 45 is lower than the first fixed cam 45.
They are arranged on both the left and right sides of the route so that the number 6 is located on the lower side.

The drive gear wheel 4 of the circulation transfer device 1, the drive gear wheel 30 of the high-speed rotation means 27 in the molding bar rotation device 10, and the drive roller 37 of the material holding belt device 11 are intermittent wheels linked to one drive motor. They are interlocked and connected to the output shaft of a drive means (not shown), and are driven intermittently in synchronization with each other. Each molded cup 7 in the circulation transfer device 1 is intermittently circulated by a unit distance (for example, one pitch of molded cups 7) by a pair of left and right conveyor chains 6 which are intermittently driven via a drive gear 4. The endless roller chain 32 of the high-speed rotation means 27 in the molding bar rotating device 10 rotates along a path such that the upper path portion that engages the tooth ring 23 of each molding cup 7 is different from the direction of movement of the molding cup 7. Rotates intermittently to move in the opposite direction. In addition, the material holding belt device 11
The endless belt 39 has a material holding path portion 39a.
rotates intermittently so as to move in synchronism with the molded cup 7 below it in the same direction and at the same speed.

At the same time as each device is driven as described above, the viscous material quantitative supply device 8, core supply device 9, etc. are also driven in conjunction with each other, so that the molded cup 7 stopped below the viscous material quantitative supply device 8. Each molding recess 1
5, a fixed amount of viscous material M1 is supplied as shown in FIG. 10A, and when this forming cup 7 stops under the next core supply device 9, as shown in FIG. 10B The molded recess 15 is formed by the core supply device 9.
A core material M2 such as a boiled egg is placed on top of the viscous material M1 inside, but before the forming cup 7 arrives at the viscous material quantitative supply device 8, the forming bar 17 inside each forming recess 15 is positioned at the deepest position P1 of the molding recess 15 as shown in the figure.

That is, if the molding bar 17 is located right above the molding recess 15 and the first cam driven part 22 is located right below the rotating shaft 18 as shown in FIG. When the formed cup 7 moves from the lower return path 3 to the starting end of the upper horizontal conveyance path 2, as the formed cup 7 moves forward, the first cam follower 22 moves as shown in FIG. 11B.
is rotated by the cam surface 45a of the first fixed cam 45 to the rear position of the rotating shaft 18, and the molding bar 17 is rotated 90 degrees forward and downward from the position directly above the molding recess 15. Therefore, the second cam driven portion 24 is displaced to a position directly below the rotating shaft 18.

Next, when the molded cup 7 passes the position of the second fixed cam 46, the second cam driven part 24 enters between the pair of upper and lower cam surfaces 46a and 46b of the second fixed cam 46, as shown in FIG. 11C. As a result, the second cam driven portion 24 is rotated to the rear position of the rotating shaft 18 by the lower cam surface 46b. Therefore, the molding bar 17 is rotated backward and downward by 90 degrees to the deepest position P1 within the molding recess 15.

That is, the cam surface 45a of the first fixed cam 45 moves the first cam driven part 22 to the rear or front position of the rotary shaft 18 only when the first cam driven part 22 is in the lower half region relative to the rotary shaft 18. It is something that displaces it in either direction. Therefore, when the molded cup 7 passes the position of the first fixed cam 45, the second cam driven portion 24 is always in the latter half region with respect to the rotating shaft 18, and never in the first half region. As a result, the second cam follower 24 is always rotated backward by the pair of upper and lower cam surfaces 46a and 46b of the second fixed cam 46, and there is no possibility that it will be rotated forward ahead of the rotating shaft 18.

In other words, when the forming cup 7 moves to the starting end position of the upper horizontal conveyance path 2, the forming bar 1
No matter what position 7 is in, this forming bar 1
The first cam driven part 22 and the second cam driven part 24 interlocked with the first fixed cam 45 and the second fixed cam 46
By acting on Figures 10A and 11
As shown in FIG. C, the molding bar 17 is always positioned at the deepest position P1 of the molding recess 15 (directly below the rotating shaft 18).

As described above, with the forming bar 17 located at the deepest position P1 of the forming recess 15, the viscous material M1
When the forming cup 7 supplied with the mandrel M2 passes through the position of the low-speed rotation means 26 in the forming bar rotating device 10, the gear ring 23 engages with the fixed roller chain 29 as shown in FIG. 10C. By rolling, each molding bar 17 is
rotates within the molding recess 15 by a predetermined number of rotations, for example, about one rotation, around the rotation shaft 18. Therefore, the viscous material M1 in the molding recess 15
As the forming bar 17 rotates at low speed, the core M2
It rotates slowly around the core M2, and roughly wraps around the core M2. When this molded cup 7 passes the next high speed rotation means 27,
As shown in FIGS. 10D and E, the gear 23 meshes with the rotating endless roller chain 32, so that the endless roller The molding bar 17 rotates within the molding recess 15 many times at a high speed corresponding to the rotational speed of the chain 32. As a result, the viscous material M1 in the molding recess 15 becomes the spherical inner bottom surface 15 of the molding recess 15.
As the molding bar 17 rotates at high speed in sliding contact with a, it rotates at high speed around the core M2, and is molded so as to completely wrap around the core M2.

In this way, the forming bar 17 is rotated by the high-speed rotating means 27.
In the first half of the stroke where is driven to rotate at high speed,
The material holding path portion 39a of the endless belt 39 of the material holding belt device 11 is connected to each forming cup 7.
are in contact with the surface of the object and are moving together. Therefore, as shown in FIGS. 10D and E, when the forming bar 17 protrudes upward from the forming recess 15 and rotates, the forming bar 17 touches the endless belt 3.
9 while pushing up the material pressing path portion 39a against the weight of the pressing roller 40,
The viscous material M1, which rotates following the rear side of the forming bar 17, is held down by the endless belt 39 and separated from the forming bar 17. As a result, the viscous material M1 and the core M2 in the molding recess 15
The material holding path portion 39a of the endless belt 39 prevents the material from rotating together with the forming bar 17, and the viscous material M1 in the forming recess 15 is reliably cored by the forming bar 17. It is wrapped around the tool M2.

Since the forming bar 17 in the forming cup 7 is rotated at high speed as described above by the high-speed rotation means 27 of the forming bar rotation device 10 even after being separated from the material holding belt device 11, in this step, As shown in FIG. 10F, the peripheral surface of the viscous material M1 surrounding the core M2 is beautifully molded by the spherical inner bottom surface 15a of the molding recess 15, resulting in a substantially spherical molded product surrounding the core M2. Finished in 47.

The molded cup 7 that has escaped the molding process caused by the rotation of the molding bar 17 rotates around the drive gear 4 from the upper horizontal conveyance path 2 of the circulation transfer device 1, moves to the lower return path 3, and moves downward. Molded product discharge section 1
2, but this molded product discharge section 12 has a first
8 and 10G, an endless roller chain 48 capable of forcibly rotating is disposed at a position where it can engage the gear 23, and the molding bar rotating device 10 is rotated at high speed. In the same way as when the molding bar 17 is rotated by the rotating means 27, the molding bar 17 is forcibly rotated within the molding recess 15 which is facing downward, thereby molding is performed from within the molding recess 15 which is facing downward. The product 47 can be forcibly scraped out. Of course, instead of the endless roller chain 48 which is forcibly driven to rotate, the forming bar rotating device 1 is used.
It is also possible to provide a fixed roller chain or the like which engages the toothed wheel 23 as well as the low speed rotation means 26 of 0.

The molded product 47 discharged from the molded product discharge section 12 as described above is supplied to the automatic deep-frying machine 13 via the chute 14, and undergoes a deep-frying process to become a deep-fried food with a core.

Note that the molding bar rotating device 10 is not limited to that of the above embodiment. For example, it may be configured with only either the low speed rotation means 26 or the high speed rotation means 27. Further, the material holding belt device 11 is not essential to the present invention.

In the above embodiment, the core-containing molded product 47 having a substantially spherical shape is molded, but by changing the shape of the molding recess 15 of the molding cup 7 and the molding bar 17, it is possible to mold a cylindrical core-containing molded product 47 like a burdock. It is possible to mold a molded product in any shape of a rotating surface. Of course, solid materials are generally used as the core M2, but
In some cases, semi-solid substances such as cream and bean paste can also be used.

(Operations and Effects of the Invention) As described above, according to the continuous molding machine for core-containing foods of the present invention, a predetermined amount of molding is carried out by an appropriate means into the molding recess of each molding cup that rotates in a row in the circulation path. By supplying the viscous material and the core, when the molding cup passes through the position of the molding bar rotating device, the molding bar in the molding recess is moved along the inner bottom surface of the molding recess, which has an arcuate longitudinal section. The viscous material inside the molding recess can be rotated automatically to wrap around the core, but before supplying the viscous material or the core into the molding recess, The bar can be automatically positioned at the deepest position within the molding recess.

That is, by the first fixed cam 45 acting on the first cam driven part 22 provided on the driving rotating shaft 18 of the molding bar, the second cam driven part 24 is once positioned in the latter half region with respect to the rotating shaft 18. However, since the second fixed cam 46 then positions the second cam driven part 24 at the rear position of the rotating shaft 18, no matter what position the second cam driven part 24 is in, the final result is By positioning the second cam driven portion 24 at a rear position of the rotating shaft 18, it is possible to position the molding bar at the deepest position of the molding recess.

As described above, according to the configuration of the present invention, a viscous material can be processed using an extremely simple structure consisting of two cam driven parts provided on the rotating shaft for driving the forming bar and two fixed cams provided on the path side. The molding bar can be reliably positioned at the deepest position of the molding recess before the supply position of the core, and the viscous material and core can be reliably supplied to the molding recess without being obstructed by the molding bar. It can be done well.

By using the molding machine of the present invention, it is possible to reliably and continuously mass-produce various food materials with cores to be supplied to the deep-frying and baking processes without relying on human labor. Homogenization and cost reduction can be achieved.
