DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment for carrying out the present invention will be described in detail with reference to the drawings attached to the application.

[0012] In the following embodiment, a skewered food manufacturing device using minced chicken meat will be described, but the device can also be configured in the same way to manufacture skewered food using materials that are less elastic than dumpling dough made from rice flour, such as minced meat of animal or fish meat, glutinous rice material, ohagi material, domyoji material, warabimochi material, kudzu material, etc.

[0013] In addition, in the embodiment shown below, a case where a flat skewer is used as the skewer P is shown, but the same configuration can also be used when a skewer P other than a flat skewer, such as a five-sided skewer, a square skewer, a round skewer, or a gun skewer, is used.

[0014] In the following description, the vertical direction is referred to as the up-down direction, the skewering direction along the horizontal direction (the direction in which the skewer P is pushed out) is referred to as the front-to-back direction, and the direction perpendicular to the vertical direction and the skewering direction is referred to as the left-to-right direction. In some drawings, one of the front-to-back directions (the skewering direction) is indicated by an arrow x, and one of the up-to-down directions (upward) is indicated by an arrow z.

[0015] FIG. 1 is a front view showing an embodiment of a skewered food manufacturing apparatus 1 according to the present invention, and FIG. 2 is a functional block diagram of the skewered food manufacturing apparatus 1 of FIG.

[0016] As shown in FIGS. 1 and 2, the skewered food manufacturing apparatus 1 of this embodiment is generally composed of a dough supplying device 40, a forming device 10, a skewering device 20, a skewered food conveying device (not shown), and a positioning connecting mechanism 50.

[0017] The dough supplying device 40 is disposed above the forming device 10 and supplies dough made from ground chicken meat to the forming device 10. The forming device 10 forms formed foods from the dough supplied by the dough supplying device 40 and holds the formed formed foods at a predetermined skewering position. The skewering device 20 skewers the formed foods held at the skewering position by the forming device 10 with skewers P. The skewering device 20 is provided separately from the forming device 10 and can be separated from the forming device 10. The skewered food transporting device has a belt conveyor (not shown) that transports skewered formed foods skewered by the skewering device 20 and released from the forming device 10. The positioning connecting mechanism 50 detachably connects the forming device 10 and skewering device 20 to prevent relative movement between them.

[0018] In the skewered food manufacturing apparatus 1 of this embodiment, the forming device 10 and the skewering device 20 are detachably connected, but the skewering device may be incorporated into the forming device. Figures 3 to 6 are drawings for explaining the basic configuration and operation of the skewered food manufacturing apparatus 1, and therefore the shapes of the forming rolls shown in Figures 3 to 6 differ from the shapes of the forming rolls of the present invention shown in Figures 7 and 8. The dough supplying device 40 is not shown in any figures other than Figure 2.

[0019] The dough supply device 40 is configured to include a dough hopper 41 and a screw conveying device 42 having a pair of screws (not shown), and is disposed above the molding device 10. Dough made from ground chicken meat is placed in the dough hopper 41, and the screw conveying device 42 supplies the dough in the dough hopper 41 to the molding device 10.

[0020] 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 dough supplied from the dough supply device 40 between the first and second forming rolls 10A and 10B. The rotation axis of the first and second forming rolls 10A and 10B both extend in the front-to-rear direction.

[0021] The skewering device 20 is generally composed of a skewer hopper 21 into which a large number of skewers P (in this embodiment, a large number of flat skewers) are fed, a skewer alignment roll 22 that takes out the skewers P fed into the skewer hopper 21 one by one and aligns and transports them, a skewer rail 23 (see Figure 6) having a skewer guide groove 24 on its periphery into which the skewers P aligned and transported by the skewer alignment roll 22 fall one by one, and a skewer push-out device 25 that pushes the skewers P that have fallen into the skewer guide groove 24 forward toward the forming device 10. The rotation axis of the skewer alignment roll 22 extends in the front-to-rear direction.

[0022] The positioning and connecting mechanism 50 guides and positions the skewering unit 27 at the assembly position, and also connects the skewering device 20 to the forming device 10, thereby maintaining the skewering unit 27 in an assembled state.

[0023] The skewered food formed by the forming device 10 and skewered at the skewering position of the skewering device 20 is released from the second forming roll 10B of the forming device 10 and falls onto the skewered food conveying device 40 for transport.

[0024] Next, a detailed description will be given of the main parts of the skewering device 20 of the skewered food production apparatus 1 shown in Fig. 2. Fig. 3 is a side view of the main parts of the forming device 10 and skewering device 20 of the skewered food production apparatus 1.

[0025] In Figure 3, the skewers P (flat skewers in this embodiment) used in the skewered food production apparatus 1 of this embodiment are placed into the skewer hopper 21. A pendulum device 61 is provided inside the skewer hopper 21 to level the skewers P and sequentially discharge them from the bottom surface of the skewer hopper 21. The pendulum device 61 is configured with a pendulum member 62 and a pendulum cam 63, and the pendulum member 62 levels the skewers P in the skewer hopper 21 and sequentially discharges them from the bottom surface of the skewer hopper 21.

[0026] The skewers P discharged from the skewer hopper 21 by the pendulum device 61 are guided to a first skewer conveying path 64A that is inclined upward at a predetermined angle. At the lower end of this first skewer conveying path 64A, a skewer feeding blade 65 is provided that carries the skewers P sequentially discharged from the skewer hopper 21 one by one onto the first skewer conveying path 64A.

[0027] Moreover, above the first skewer conveying path 64A, a rotary brush 66 is provided which rotates in a direction returning the skewers P on the first skewer conveying path 64A to align the skewers P on the first skewer conveying path 64A.

[0028] At the upper end of the first skewer conveying path 64A, a second skewer conveying path 64B is provided which is inclined downward at a predetermined angle and conveys downward the skewers P which have reached the upper end of the first skewer conveying path 64A.

[0029] A skewer pressing member 67 is provided above the second skewer conveying path 64B to press down the skewers P being conveyed on the second skewer conveying path 64B from above, and a skewer pressing roll 68 is provided at the tip of the skewer pressing member 67 to press down the skewers P stored in the skewer grooves 31 of the skewer alignment roll 22 from above through the second skewer conveying path 64B.

[0030] The skewer alignment roll 22 of the skewering device 20 is arranged with its outer peripheral surface close to the lower end of the second skewer conveying path 64B, and stores the skewers P conveyed on the second skewer conveying path 64B in the skewer groove 31 and conveys them to a skewer waiting position behind the skewering position of the molded food.

[0031] 3 and 5, a skewer rail 23 having a skewer guide groove 24 is disposed at the skewer waiting position for the molded food product, and the skewer rail 23 has a skewer guide groove 24 that accommodates the skewers P that have fallen from the skewer groove 31 of the skewer alignment roll 22 so that their width direction is vertical. A skewer pushing device 25 is provided in the skewer guide groove 24 to push the skewers P toward (forward from) the molded food product formed by the forming rolls 10A and 10B.

[0032] The skewer alignment roll 22 and the skewer extrusion device 25 are driven intermittently in synchronization with the intermittent driving of the first forming roll 10A and the second forming roll 10B. As the first forming roll 10A and the second forming roll 10B rotate, the first forming groove portion 17A and the second forming groove portion 17B reach the position (skewering position) of the skewer rail 23 as shown in Figure 8. When the forming of the molded food is completed, the first forming roll 10A and the second forming roll 10B stop rotating. At this time, the skewer P in the skewer guide groove 24 is pushed out by the skewer extrusion device 25 in the direction (forward) toward the molded food formed by the first forming groove portion 17A and the second forming groove portion 17B, and the molded food is skewered.

[0033] The skewered food skewered by the skewering device 20 leaves the first forming groove 17A of the first forming roll 10A and the second forming groove 17B of the second forming roll 10B, and is carried out by the skewered food transport device.

[0034] 4 is a side view of the main part of the forming device of FIG. 2, FIG. 5 is an enlarged side view of the main part of the forming device of FIG. 2, and FIG. 6 is a cross-sectional view of the main part of the forming device and skewering device of FIG.

[0035] 4 to 6, the skewered food manufacturing apparatus 1 of this embodiment is configured with a pair of forming rolls consisting of a first forming roll 10A that is intermittently driven to rotate and a second forming roll 10B that is also intermittently driven to rotate and is positioned diagonally below the first forming roll 10A. The first forming roll 10A and the second forming roll 10B are positioned so that their outer circumferential surfaces are in contact with each other.

[0036] The outer circumferential surface of the first forming roll 10A is formed with a plurality of first forming grooves 17A arranged at regular intervals (spaced apart by a predetermined angle), and the outer circumferential surface of the second forming roll 10B is formed with a plurality of second forming grooves 17B arranged to correspond to the first forming grooves 17A of the first forming roll 10A. In this embodiment, the outer diameter of the first forming roll 10A and the outer diameter of the second forming roll 10B are the same (same diameter), and the number of first forming grooves 17A and the number of second forming grooves 17B are the same (same number). The first and second forming grooves 17A, 17B are groove-shaped recessed in an arc shape from the outer circumferential surfaces of the first and second forming rolls 10A, 10B and extend in the front-to-rear direction.

[0037] Dough is inserted between the first forming roll 10A and the second forming roll 10B from a dough supplying device 40, and the supplied dough is clamped between the first forming roll 10A and the second forming roll 10B to form a formed food product. The first and second forming rolls 10A, 10B rotate intermittently so that the first and second forming grooves 17A, 17B temporarily stop at the skewering position.

[0038] In other words, as the first and second forming groove portions 17A, 17B reach the skewering position where the outer peripheral surface of the first forming roll 10A and the outer peripheral surface of the second forming roll 10B meet, the forming device 10 sandwiches the dough between the first forming groove portion 17A and the second forming groove portion 17B to form a formed food product, holds the formed formed food product at the skewering position for a predetermined time, and then moves the formed food product from the skewering position by the first and second forming rolls 10A, 10B.

[0039] The state in which the first and second forming grooves 17A, 17B have reached the skewering position refers to a state in which the center plane 16A of the first forming groove 17A (a plane passing through the deepest position of the first forming groove 17A and the central axis of rotation of the first forming roll 10A) has reached the skewering position, and the center plane 16B of the second forming groove 17B (a plane passing through the deepest position of the second forming groove 17B and the central axis of rotation of the second forming roll 10B) has reached the skewering position. In this state, the center plane 16A of the first forming groove 17A and the center plane 16B of the second forming groove 17B are substantially flush with each other.

[0040] The first forming roll 10A is provided with a plurality of first skewer insertion grooves 32A (the same number as the first forming grooves 17A) corresponding to the plurality of first forming grooves 17A, and the second forming roll 10B is provided with a plurality of second skewer insertion grooves 32B corresponding to the plurality of second forming grooves 17B. In this embodiment, the number of first skewer insertion grooves 32A and the number of second skewer insertion grooves 32B are the same.

[0041] A first roll rear end plate portion 18A and a first roll front end plate portion 19A, which are circular and have approximately the same outer diameter (same diameter) as the first forming roll 10A, are fixedly provided on the rear end surface and the front end surface of the first forming roll 10A, respectively, and a second roll rear end plate portion 18B and a second roll front end plate portion 19B, which are circular and have approximately the same outer diameter (same diameter) as the second forming roll 10B, are fixedly provided on the front end surface and the rear end surface of the second forming roll 10B, respectively.

[0042] The first and second skewer insertion grooves 32A, 32B have arc-shaped recesses that are shallower and smaller than the first and second forming grooves 17A, 17B, and are recessed from the outer circumferential surfaces of the first and second roll rear end plate portions 18A, 18B. The first skewer insertion groove 32A is positioned so that its center plane (a plane passing through the deepest position of the first skewer insertion groove 32A and the central axis of rotation of the first forming roll 10A) substantially coincides with the center plane 16A of the first forming groove 17A. The second skewer insertion groove 32B is positioned so that its center plane (a plane passing through the deepest position of the second skewer insertion groove 32B and the central axis of rotation of the second forming roll 10B) substantially coincides with the center plane 16B of the second forming groove 17B.

[0043] The first skewer insertion groove 32A and the second skewer insertion groove 32B face each other at the skewering position to define the skewer insertion section 33. In this embodiment, the skewer insertion section 33 is cylindrical, with its center on the tangent line between the first forming roll 10A and the second forming roll 10B. The skewer P pushed out by the skewering unit 27 moves on the skewer rail 23, passes through the skewer insertion section 33, and is inserted into the molded food product P.

[0044] As shown in Fig. 7, the first forming roll 10A and the second forming roll 10B are arranged such that the circumferential surfaces thereof are in contact with each other in a state where the first forming roll 10A is positioned above the second forming roll 10B, and rotate intermittently so that the first and second forming groove portions 17A and 17B temporarily stop at the piercing position where the circumferential surfaces are in contact with each other. During the process in which the first and second forming groove portions 17A and 17B reach the piercing position, a food dough is sandwiched between the first forming groove portion 17A and the second forming groove portion 17B to form a formed food. <> <>

[0045] <> The state where the first forming roll 10A is positioned above the second forming roll 10B means that the rotation center axis OA of the first forming roll 10A is positioned above the piercing position (piercing insertion portion 33) where the first forming roll 10A and the second forming roll 10B are in contact with each other, and the rotation center axis OB of the second forming roll 10B is positioned below the piercing position (piercing insertion portion 33). <> <>

[0046] <> The groove depth LB of the second forming groove portion 17B from the piercing insertion position by the piercing device 20 is shallower than the groove depth LA of the first forming groove portion 17A from the piercing insertion position (LB < LA). The plane passing through the rotation center axis OA of the first forming roll 10A and the rotation center axis OB of the second forming roll 10B passes through the tangent line (roll tangent line) of the first forming roll 10A and the second forming roll 10B, and substantially coincides with the center plane 16A of the first forming groove portion 17A, the center plane 16B of the second forming groove portion 17B, the center plane of the first piercing through groove portion 32A, and the center plane of the second piercing through groove portion 32B at the piercing position. The groove depth LA of the first forming groove portion 17A from the piercing insertion position is defined by the distance from the roll tangent line to the deepest position of the first forming groove portion 17A, and the groove depth LB of the second forming groove portion 17B from the piercing insertion position is defined by the distance from the roll tangent line to the deepest position of the second forming groove portion 17B. <> <>

[0047] <> The shapes and numbers of the first and second forming groove portions 17A and 17B are not limited to the form example of Fig. 7, and other shapes and numbers may be used. Fig. 8 shows other form examples of the first and second forming groove portions 17A and 17B. <> <>

[0048] <> According to this embodiment, the groove depth LB of the second forming groove portion 17B from the skewer insertion position is shallower than the groove depth LA of the first forming groove portion 17A from the skewer insertion position, so the forming space defined by the first forming groove portion 17A and the second forming groove portion 17B at the skewer insertion position is deeper above the skewer P and shallower below the skewer P. Therefore, even when using a material that is less elastic than dumpling dough made from rice flour or the like and that is easily deformed by its own weight, it is possible to reduce displacement of the skewer from the center of the formed food.

[0049] The present invention is not limited to the above-described embodiments, which have been described as examples, and various modifications can be made depending on the design, etc., even if they are other than the above-described embodiments, as long as they do not deviate from the technical idea of ​​the present invention.
