  Hereinafter, a food coating device 1 according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the food coating device 1 includes a belt conveyor 2, a liquid flow-down unit 3, a liquid storage unit 4, a conveyance assisting unit 5, and a drop delay unit 6.

  The belt conveyor 2 conveys the object 10 with an endless annular belt 23. The liquid flow-down means 3 is provided above the belt conveyor 2. The liquid storage means 4 is provided below the belt conveyor 2. The conveyance assisting means 5 is provided inside the endless annular belt 23. The belt conveyor drop delay means 6 is provided near the downstream end of the belt conveyor 2.

  As shown in FIG. 1, the belt conveyor 2 has an endless annular belt 23, an upstream pulley 21, and a downstream pulley 22. In FIG. 1, the direction indicated by arrow A is the direction from the upstream side to the downstream side in the transport direction.

  As shown in FIG. 2, the endless annular belt 23 includes six multi-row belts 23a and three multi-row belts 23b. In the multi-row belt 23a and the multi-row belt 23b, the endless annular belt 23 is hung on the upstream pulley 21 on the upstream side, and the endless annular belt 23 is hung on the downstream pulley 22 on the downstream side. The multi-row belt 23a and the multi-row belt 23b are arranged in parallel at right angles to the transport direction.

  As shown in FIGS. 2 and 3, the upstream pulley 21 has a cylinder 21a and a cylinder 21b having different radii fixed to the rotation axis. As shown in FIG. 7, when the target object 10 is placed, the upper side in FIG. 7 is one end of the target object 10 and the lower side is the other end of the target object 10.

  As shown in FIGS. 2 and 7, a part of the pulley on the other end side of the object 10 is a column 21b. The pulley of the other part of the object 10 is a cylinder 21a.

  As shown in FIGS. 2 and 3, the six multi-row belts 23a are hung on the side peripheral surface of the column 21a having a large radius. The three multi-row belts 23b are hung on the side peripheral surface of the cylinder 21b having the smaller radius. A plurality of grooves for guiding the multi-row belts 23a are formed on the side peripheral surface of the column 21a at predetermined intervals in the axial direction. Grooves for guiding the multi-row belts 23b are formed on the side peripheral surface of the column 21b.

  When the rotation shaft that fixes the cylinder 21a and the cylinder 21b rotates, the transport speed of the multi-row belt 23b hung on the cylinder 21b becomes slower than the transport speed of the multi-row belt 23a hung on the cylinder 21a. .

  As shown in FIG. 4, the downstream pulley 22 has a plurality of extending portions that extend radially. A recess into which the multi-row belt 23a or the multi-row belt 23b fits is formed at the tip of each extending portion. The downstream pulley 22 contacts the multi-row belt 23a or the multi-row belt 23b at the tips of the plurality of extending portions.

  As shown in FIG. 2, as many downstream-side pulleys 22 as the total number of multi-row belts 23a and multi-row belts 23b are attached to the shaft at predetermined intervals in the axial direction. Each of the downstream pulleys 22 is not fixed to the shaft and can freely rotate with respect to the shaft.

  In FIGS. 1 and 2, the upstream pulley 21 and the downstream pulley 22 are rotated in the direction of arrow α by a drive motor (not shown). By the rotation of the upstream pulley 21 and the downstream pulley 22, the multi-row belt 23a and the multi-row belt 23b can be circulated between the upstream side and the downstream side in the transport direction.

  The multi-row belt 23a and the multi-row belt 23b are arranged in parallel from the upstream pulley 21 toward the downstream pulley 22.

As shown in FIG. 1, the liquid flow-down means 3 causes the liquid 30 to flow down toward an object conveyed by the belt conveyor 2.
The liquid flow-down means 3 has a chute plate 31 that guides the position at which the liquid 30 flows down. The chute plates 31 are provided at four places at intervals in the carrying direction.

  Each chute plate 31 is movable in the width direction of the belt conveyor 2 as shown by a double-headed arrow B in FIG. By moving the chute plate 31, the range of the object to be coated with the liquid 30 can be adjusted.

  As shown in FIG. 1, a liquid supply pipe 47 is connected to the liquid flow-down means 3 and the liquid storage means 4. The liquid 30 is supplied from the liquid storage means 4 to the liquid flow-down means 3 through the liquid supply pipe 47.

  1 and 2, although the configuration is partially omitted, the liquid 30 stored in the liquid storage means 4 is supplied to the liquid flow-down means 3, and the liquid 30 flowed down by the liquid flow-down means 3 is recovered. It is possible to circulate the liquid 30 by storing the recovered liquid 30 in the liquid storage means 4 and supplying the liquid 30 to the liquid flow-down means 3 again.

  As shown in FIG. 6, the liquid storage unit 4 has an outer box 42 and an inner box 41.

  The inner box 41 is fixed inside the outer box 42 by an inner box fixing member 43.

  A fluid can be stored in the outer box 42. As for the fluid, the fluid stored in the outer box 42 can be circulated by the pump 48, the fluid supply pipe 45, and the fluid discharge pipe 46. By circulating the fluid and cooling or heating the fluid, it is possible to suppress the temperature change of the fluid.

  The inner box 41 can store the coating liquid 30. The inner box 41 is a space for storing the liquid 30 of the liquid storage means. A cylindrical body 44 penetrates through the inner box 41. Both ends of the tubular body 44 are open to the internal space of the outer box 42. Therefore, the fluid stored in the outer box 42 can pass through the inside of the cylindrical body 44.

  Since the temperature change of the fluid stored in the outer box 42 is suppressed, the temperature of the coating liquid 30 stored in the inner box 41 can be suppressed by the fluid passing through the cylindrical body 44.

  As shown in FIGS. 1, 2 and 7, the conveyance assisting means 5 includes upstream gears 54a and 54b, downstream gears 55a and 55b, chains 51a and 51b, a bridge portion 52, and a claw portion 53. Have.

  The upstream gears 54a and 54b are a pair of gears that face each other in the width direction of the belt conveyor 2. The downstream gears 55a and 55b are also a pair of gears facing each other in the width direction of the belt conveyor 2.

  The chain 51a is spanned by an upstream gear 54a and a downstream gear 55a that are lined up in the transport direction. The chain 51b is spanned by an upstream gear 54b and a downstream gear 55b that are lined up in the transport direction. The two chains 51a and 51b are arranged in parallel in the carrying direction.

  A plurality of bridging portions 52 are provided at predetermined intervals between the two chains 51a and 51b that are parallel to each other.

  As shown in FIGS. 2 and 7, a plurality of claw portions 53 are formed so as to extend upward from the respective bridging portions 52. The claw portion 53 projects upward from between the multi-row belts 23a and 23b.

  The upstream gears 54a and 54b and the downstream gears 55a and 55b rotate in the direction of arrow β in FIG. The claw portion 53 moves in the same direction as the conveyance direction of the belt conveyor 2.

  The speed of the multi-row belt 23 in the transport direction is lower than the speed of the claw portions 53 in the transport direction. Therefore, in a section in which the claw portion 53 projects upward from between the multi-row belts 23a and 23b and moves in the same direction as the multi-row belts 23a and 23b, the pawl portion 53 is placed on the multi-row belt 23a and the multi-row belt 23b. The object 10 placed is pressed against the claw portion 53.

  When the food coating device 1 is, for example, a frying buttering device, the object 10 is shrimp and the liquid 30 is a batter. The chute plates 31 for allowing the batter to flow down are provided at four positions with intervals in the transport direction.

  If the shrimp passes under the chute plate 31 on the most upstream side and is coated with the batter, the shrimp may be bent due to the high viscosity of the batter.

  However, by pressing the shrimp, which is the object 10, against the claw portion 53, it is possible to prevent the shrimp from bending even when passing below the chute plate 31 on the downstream side. Thereby, the batter can be uniformly coated on the surface of the shrimp.

  The drop delay means 6 is provided near the downstream end of the belt conveyor 2. The drop delay means 6 has a support member 61 and a swing member 62.

  The other end of the object 10 conveyed while being placed on the belt conveyor 2 contacts the swing member 62. Due to the contact between the other end of the object 10 and the swinging member 62, the fall of the other end of the object 10 is delayed at the downstream end of the belt conveyor than the one end of the object 10 falls. .
