The following describes in detail an embodiment of the present invention, with reference to the drawings attached to this application.

In the following examples, a skewered food production device using minced chicken meat will be described, but the same configuration can also be used for skewered food production devices using minced meat such as game or fish meat, glutinous rice material, ohagi material, domyoji material, warabimochi material, kudzu material, etc.

In addition, the following examples show the use of flat skewers P, but the same configuration can also be used when using five-sided skewers, square skewers, round skewers, gun skewers, etc.

Figure 1 is a side view showing one embodiment of a skewered food production apparatus 100 according to the present invention, Figure 2 is a top view of the skewered food production apparatus 100 shown in Figure 1, and Figure 3 is an internal explanatory diagram illustrating the main internal components of the skewered food production apparatus shown in Figure 1.

In Figures 1 to 3, the skewered food manufacturing apparatus 100 of this embodiment is comprised of a dough supplying device 30 that supplies dough made from ground chicken meat, a forming device 10 that forms formed foods from the dough supplied by the dough supplying device 30, a skewering device 20 that skewers the formed foods formed by the forming device 10 with flat skewers P, and a skewered food transporting device 40 consisting of a belt conveyor that removes and transports the skewered formed foods skewered by the skewering device 20 from the forming device 10.

The dough supply device 30 is equipped with a dough hopper 31 and a screw conveying device 37 having a pair of screws 33a, 33b, which will be described in detail later with reference to Figure 5. Dough made from ground chicken meat is placed into the hopper 31, and the screw conveying device 37 supplies the dough in the hopper 31 to the molding device 10.

The forming device 10 is equipped with a pair of first and second forming rolls 10a and 10b, and forms a formed food product by sandwiching the dough supplied from the dough supply device 30 between the first and second forming rolls 10a and 10b.

The skewering device 20 has a skewer hopper 21 into which a large number of skewers, in this embodiment a large number of flat skewers P, is fed. The skewer roll 22 removes the flat skewers P fed from the skewer hopper 21 one by one, aligns them, and transports them. The flat skewers P aligned and transported by the skewer roll 22 are dropped onto a skewer rail 230 (shown in Figure 7, which will be explained later). The flat skewers P dropped onto this skewer rail 230 are then pushed toward the molding device 10 by a skewer extrusion device 23, where they are skewered into the molded food products.

The skewered food product formed by the forming device 10 and skewered by the skewering device 20 is released from the second forming roll 10b of the forming device 10, falls onto the skewered food conveying device 40, and is transported in the direction of the arrow shown in Figure 2.

Figure 4 is a side view showing details of the dough supply device 30 of the skewered food manufacturing apparatus 100 shown in Figure 1, and Figure 5 is a top view showing details of the screw conveying device 37 of the dough supply device 30 shown in Figure 4.

In Figure 4, the dough supply device 30 of this embodiment is composed of a dough hopper 31 into which dough made from ground chicken meat is poured, and a screw conveying device 37 disposed below the dough hopper.

The dough hopper 31 is equipped with a stirring blade 312 that stirs the dough inside the dough hopper 31, and a screw-type extrusion device 313 that extrudes the dough inside the dough hopper 31 downward.

The dough extruded by the extrusion device 313 in the dough hopper 31 is guided to the screw conveying device 37.

As shown in Figure 5, the screw conveying device 37 has a pair of screws 33a, 33b arranged horizontally opposite each other and rotating in opposite directions. The dough guided from the extrusion device 313 is conveyed horizontally along the horizontal conveying path 32 and discharged from a nozzle 34 provided on the horizontal conveying path 32.

Here, as shown in Figure 5, the pair of screws 33a, 33b are each attached to the output shaft of a gearbox 35. Rotation of the input shaft 35a of the gearbox 35 rotates the screw 33a in the R1 direction and the screw 33b in the R2 direction, thereby allowing the dough introduced from the extrusion device 313 in the dough hopper 31 to be transported horizontally along the horizontal transport path 32 to the die 34.

In this embodiment, the side wall 31a of the dough hopper 31 and the housing 37a of the screw conveying device 37 each have a double structure, and a temperature-regulating medium such as cold water input from port P1 is circulated through the double structure of the side wall 31a of the dough hopper 31, port P2, the double structure of the housing 37a of the screw conveying device 37, and port P3, thereby making it possible to appropriately control the temperature of the dough supplied from the dough supplying device 30 to the molding device 10.

If the temperature of the dough supplied from the dough supply device 30 to the forming device 10 is not appropriate, the dough will run, preventing proper formation of the formed food in the forming device 10 and proper skewering by the skewering device 20, which will be described later.

Next, we will explain in detail the main parts of the skewering device 20 of the skewered food manufacturing apparatus 100 shown in Figure 2.

Figure 6 is a side view showing details of the main parts of the skewering device 20 of the skewered food manufacturing apparatus 100 shown in Figure 2.

In Figure 6, the skewers used in the skewer food production apparatus 100 of this embodiment (flat skewers P in this embodiment) are placed into the skewer hopper 21. Inside the skewer hopper 21 is a pendulum device 120 that flattens the flat skewers P and sequentially discharges them from the bottom. This pendulum device 120 is composed of a pendulum member 121 and a pendulum cam 122, and the pendulum member 121 flattens the flat skewers P in the skewer hopper 21 and sequentially discharges them from the bottom.

Flat skewers P discharged from the skewer hopper 21 by the pendulum device 120 are guided to the first skewer conveying path 140-1, which is inclined upward at a predetermined angle. At the lower end of this first skewer conveying path 140-1, a skewer feed blade 150 is provided, which conveys the flat skewers P sequentially discharged from the skewer hopper 21 one by one onto the first skewer conveying path 140-1.

In addition, a rotating brush 160 is provided above the first skewer conveying path 140-1, which rotates in the direction returning the flat skewers P on the first skewer conveying path 140-1 to align the flat skewers P on the first skewer conveying path 140-1.

A second skewer conveying path 140-2 is provided at the upper end of the first skewer conveying path 140-1, inclined downward at a predetermined angle to convey flat skewers P downward once they reach the upper end of the first skewer conveying path 140-1.

Above the second skewer conveying path 140-2, a skewer pressing member 170 is provided to press down from above the flat skewers P being conveyed on the second skewer conveying path 140-2, and at the tip of the skewer pressing member 170, a skewer pressing roll 171 is provided to press down from above the flat skewers P that have been stored in the skewer grooves 22a of the skewer roll 22 from the second skewer conveying path 140-2.

The skewer roll 22 of the skewering device 20 is positioned so that the generatrix of its outer surface is close to the lower end of the second skewer conveying path 140-2, and stores flat skewers P conveyed along the second skewer conveying path 140-2 in the skewer grooves 22a and conveys them to the skewering position on the molded food product.

As shown in Figures 7 and 8, a skewer rail 230 is positioned at the skewering position of the molded food product, and has a skewer guide groove 240 that accommodates flat skewers P that fall from the skewer groove 22a of the skewer roll 22 so that their width direction is vertical. This skewer guide groove 240 is equipped with a skewer pusher 23 that pushes the flat skewers P toward the molded food product formed by the forming rolls 10a and 10b.

The skewer alignment roll 22 and skewer extrusion device 23 are driven intermittently in synchronization with the intermittent driving of the first forming roll 10a and second forming roll 10b. As the first forming roll 10a and second forming roll 10b rotate, the first groove portion 11a and second groove portion 11b reach the position of the skewer rail 23, as shown in Figure 8. When the molding of the molded food is complete, the first forming roll 10a and second forming roll 10b stop rotating. At this time, the flat skewer P in the skewer guide groove 240 is pushed by the skewer extrusion device 23 toward the molded food formed by the first groove portion 11a and second groove portion 11b, and the molded food is skewered.

The skewered food PD skewered by the skewering device 20 leaves the first groove 11a of the first forming roll 10a and the second groove 11b of the second forming roll 10b and is discharged onto the skewered food conveying device 40.

Figure 9 is a side view showing details of the forming device 10 of the skewered food manufacturing apparatus 100 according to the present invention, Figure 10 is a top view of the forming device 10 shown in Figure 9, and Figure 11 is a front view of the forming device 10 shown in Figure 9. Also, Figure 12 is a diagram showing an outline of the drive mechanism of the forming device 10 shown in Figure 9.

In Figures 9 to 12, the skewered food manufacturing apparatus 100 of this embodiment is equipped with a pair of forming rolls: a first forming roll 10a, which is driven intermittently, and a second forming roll 10b, which is in contact with the first forming roll 10a and is positioned below the first forming roll 10a.

The first molding roll 10a has multiple first grooves 11a formed at regular intervals on its circumferential surface, and the second molding roll 10b has multiple second grooves 11b formed to correspond to the first grooves 11a of the first molding roll 10a.

Dough is inserted between the first forming roll 10a and the second forming roll 10b from the dough supply device 30, and this dough is clamped between the first forming roll 10a and the second forming roll 10b to form a molded food product.

An air inlet 20, which will be described in detail later, is provided at the bottom of the second groove portion 11b of the second forming roll 10b.

In addition, at the contact point between the first forming roll 10a and the second forming roll 10b, a skewer rail 230 of the skewering device 20 is provided for skewering the molded food formed by the first forming roll 10a and the second forming roll 10b.

This skewered food manufacturing device 100 is configured to skewer molded foods using flat skewers P. The flat skewers P aligned by the skewer roll 22 of the skewering device 20 fall onto the skewer rail 230 provided at the interface between the first and second forming rolls 10a and 10b. The flat skewers P that have fallen onto this skewer rail 230 are then pushed by the skewer extrusion device 23 onto the molded food formed by the first and second forming rolls 10a and 10b, thereby forming the skewered food PD.

The dough side guides 140 are located at both ends of the first forming roll 10a and the second forming roll 10b and are provided to prevent the dough extruded from leaking sideways when the first forming roll 10a and the second forming roll 10b form the food product. The scrapers 150a and 150b are provided to collect any remaining meatball dough remaining on the surfaces of the first forming roll 10a and the second forming roll 10b after forming.

After the skewered food PD is formed by the first and second forming rolls 10a and 10b and skewered by the skewering device 20, it passes the point where the first and second forming rolls 10a and 10b meet and then falls freely from the second forming roll 10b onto the skewered food conveying device 40. To assist the skewered food PD in separating from the first and second forming rolls 10a and 10b, the skewered food manufacturing device 100 of this embodiment is provided with a skewer push-out plate 160 that abuts against one end of the flat skewer P of the skewered food PD when the skewered food PD separates from the first and second forming rolls 10a and 10b.

The skewer push-out plate 160 is driven by an air cylinder 170 in synchronization with the intermittent driving of the forming rolls 10a and 10b, and moves the flat skewers P of the skewered food PD in a direction away from the second forming roll 10b. The position to which the skewer push-out plate 160 is moved by this air cylinder 170 is regulated by a stopper 161, which prevents the flat skewers P from flying out of the skewered food PD.

The air cylinder 170 is composed of a guided air cylinder having a guide 171 and an actuator 172, and is configured to move the skewer pusher plate 160 a predetermined distance in the horizontal direction.

In addition, in the skewered food manufacturing apparatus 100 of this embodiment, when the skewered food PD is removed from the first forming roll 10a and the second forming roll 10b, air is blown out from the air inlet 120 between the bottom of the second groove portion 11b of the second forming roll 10b and the skewered food PD, making it easy and reliable to remove the skewered food PD from the second forming roll 10b.

Air is blown into the air inlet 120 of the second forming roll 10b through an air outlet pipe 190 from an air supply device (not shown). This air separates the bottom of the second groove portion 11b of the second forming roll 10b from the skewered food PD, making it easy and reliable to remove the skewered food PD from the second forming roll 10b.

The skewered food transport device 40, which consists of a belt conveyor, transports the skewered food PD that falls from the first forming roll 10a and the second forming roll 10b in the direction of the arrow shown in Figure 2.

In the skewered food manufacturing apparatus 100 of this embodiment, when the skewered food PD is released from the first forming roll 10a and the second forming roll 10b, a skewer push-out plate 160 is provided that abuts against one end of the flat skewer P of the skewered food PD, and air is blown in from the air blowing inlet 120 of the second forming roll 10b. The driving of this skewer push-out plate 160 and the blowing of air from the air blowing inlet 120 are synchronized with the intermittent driving of the first forming roll 10a and the second forming roll 10b.

As shown in Figure 12, this synchronization is achieved by providing a skewered food release position detection dog 113 on the intermittent drive shaft 12b of the forming roll 10b, detecting this skewered food release position detection dog 113 with a skewered food release position detection sensor 114, and controlling the air cylinder 170 and an air supply device (not shown) based on the detection output.

Figure 13 is a cross-sectional view (Figure 13(A)) and an end view (Figure 13(B)) showing details of the second forming roll 10b of the skewered food production apparatus 100 shown in Figure 1. Also, Figure 14 is a perspective view (Figure 14(A)) and an end view (Figure 14(B)) of the second forming roll 10b of the skewered food production apparatus 100 shown in Figure 1, seen from the intermittent drive shaft 12b side.

As shown in Figures 13 and 14, the second forming roll 10b used in the skewered food manufacturing apparatus 100 of this embodiment has one end connected to the intermittent drive shaft 12b, multiple second grooves 11b formed on its circumferential surface, and air inlets 120 formed in the end face at locations corresponding to the bottoms of the second grooves 11b.

When the skewered food PD is removed from the first forming roll 10a and the second forming roll 10b, air is blown into the air inlet 120 from an air supply device (not shown) through an air outlet pipe 190.

Figure 15 shows a cross-sectional view (Figure 15(A)) and an end view (Figure 15B) of the first forming roll 10a and second forming roll 10b of the skewered food manufacturing apparatus 100 shown in Figure 1.

As shown in Figure 15, the first forming roll 10a has multiple first grooves 11a formed at regular intervals on its circumferential surface, and an intermittent drive shaft 12a is connected to one end of the first forming roll 10a.

The second forming roll 10b contacts the first forming roll 10a from below, has an intermittent drive shaft 12b connected to one end, and has multiple second grooves 11b formed on its circumferential surface corresponding to the first grooves 11a. Air inlets 120 are formed on its end face at locations corresponding to the bottoms of the second grooves 11b.

The above describes one example of the present invention, but the present invention is not limited to the above embodiment, and many modifications are possible using the ordinary creative abilities of those skilled in the art, provided they fall within the scope of the technical concept of the present invention.
