Define E.

  Sector gears 57 and 58 having a series of teeth 57A and 58A that mesh with each other are attached to the shafts 47 and 50, respectively. As a result, the upper arm member 49 and the lower arm member 52 are connected to each other, and are opened and closed with the same rotation angle. The upper arm member 49 is attached with a tension coil spring 59 that urges the upper arm member 49 and the lower arm member 52 toward each other, that is, in a closed leg direction.

  A horizontal fish conveyance path including the horizontally opposed region E of the endless chains 45 and 46 is provided with a V-groove (V-shaped) guide member 60 along the fish conveyance path. The guide member 60 receives the upper endless chain 45 on the inner side, and has a slit-like opening (not shown) through which the lower endless chain 46 runs at the bottom of the V groove.

  The carry-out side chain conveyor 70 takes out the fish body to be processed from between the brush tips of the pair of rotating brushes 11 and 12, and the other side (extraction side) of the pair of rotating brushes 11 and 12, that is, FIG. , Arranged on the left side in FIG.

  The carry-out side chain conveyor 70 has a pair of upper and lower endless chains 75, 76 that are spanned between two sprockets 71, 72, 73, 74. The endless chains 75 and 76, like the endless chains 45 and 46, are roller chains in which a large number of link plates A are connected by rollers (not shown), and projecting pieces C for catching fish are integrally formed on the link plates A. ing. The protruding direction of the projecting piece C of the endless chains 75 and 76 is a side facing each other in a horizontally opposed region F of the endless chains 75 and 76 described later.

  The sprockets 71 and 73 are driven at the same speed by driving means by an electric motor not shown in the drawing. Accordingly, as shown in FIG. 1, the upper endless chain 75 rotates in the clockwise direction, and the lower endless chain 76 rotates in the counterclockwise direction. The pair of upper and lower endless chains 75 and 76 sandwich the fish body to be processed from both the upper and lower sides and take out the fish body to be processed from between the bristles of the pair of rotating brushes 11 and 12.

  Specifically, the upper sprockets 71 and 73 are rotatably supported by the upper arm member 79 by horizontal shafts 77 and 78. The upper arm member 79 is attached to a fixed frame (not shown) so as to be able to rotate substantially vertically about the axis of the shaft 78, in other words, about the rotation center of the splot 73 on the fish discharge side. .

  A tension plot 84 is attached to the upper arm member 79 by a tension arm 83. A tension plot 86 is attached to the lower arm member 82 by a tension arm 85. The tensions plot 84 gives the required tension to the upper endless chain 75 and the tensions plot 86 gives the required tension to the lower endless chain 76. The tension plots 84 and 86 are horizontally opposed regions in which the endless chains 75 and 76 are opposed to each other in parallel with each other over a predetermined section on the transport inlet side (sprockets 73 and 74 side) of the endless chains 75 and 76. Define F.

  Sector gears 87 and 88 having a series of teeth 87A and 88A meshing with each other are attached to the shafts 78 and 81, respectively. As a result, the upper arm member 79 and the lower arm member 82 are connected to each other, and the legs are opened and closed with the same rotation angle. The upper arm member 79 is attached with a tension coil spring 89 that urges the upper arm member 79 and the lower arm member 82 toward each other, that is, in a closed leg direction.

  A horizontal fish conveyance path including the horizontally opposed region F of the endless chains 75 and 76 is provided with a V-groove (V-shaped) guide member 90 along the fish conveyance path. The guide member 90 receives the upper endless chain 75 on the inner side, and has a slit-like opening (not shown) through which the lower endless chain 76 runs at the groove bottom of the V groove.

  The operation of the fish slimming device having the above-described configuration will be described.

  The device is in an on state, that is, the rotary brush device 10, the carry-in side chain conveyor 40, and the carry-out side chain conveyor 70 are all in a drive state, and the fish body W to be stripped such as sea bream is placed on the carry-in guide member 60. The fish body W is put between the endless chains 45 and 46 of the carry-in side chain conveyor 40.

  As a result, the fish body W is sandwiched from the upper and lower sides by the endless chains 45, 46, and the protruding pieces C of the endless chains 45, 46 are caught by the fish body by biting into the fish body surface. A pair of rotating brushes 11 and 12 are fed toward the brush tips.

  The vertical distance between the endless chains 45 and 46 on the right entrance side of the carry-in side chain conveyor 40 in FIGS. 1 and 2 depends on the setting of the distance between the axes of the splots 41 and 42 on the fish entrance side. Therefore, the fish body W can be easily and smoothly inserted between the endless chains 45 and 46.

  When the fish body W enters the horizontally opposed region E of the endless chains 45 and 46, the upper arm member 49 and the lower arm member 52 are pulled while being interlocked by the action of the sector gears 57 and 58 according to the thickness of the fish body W or the like. The leg is rotated against the spring force of the coil spring 59. As a result, the pair of endless chains 45, 46 can properly sandwich the fish W to be processed from both sides regardless of the thickness of the fish W to be conveyed without causing slipping or dropping. W is reliably conveyed toward the brush bristles of the rotating brushes 11 and 12.

  Furthermore, since this conveyance is performed in a state in which each projecting piece C of the endless chains 45 and 46 has caught the fish body W by biting into the fish body surface, the fish body is slender and has a slim surface that is slippery like a shark. Even in W, reliable conveyance is performed. The bite of the projecting piece C on the fish body surface is suitable for fish whose skin is strong like a carp, and the bite of the projecting piece C on the fish body surface does not damage the fish body.

  In this way, the fish that is fed between the bristles of the rotating brushes 11 and 12 is reliably conveyed by the carry-in side chain conveyor 40 while the main bristles 13 and 14 of the rotating rotating brushes 11 and 12 are rotating. The surface is rubbed by the tip.

Since the rotary brushes 11 and 12 have long-haired footbrush hairs 13a and 14a and short-haired footbrush hairs 13b and 14b that are different in length from each other when viewed in the axial direction, the long-haired feet on the surface of the swelled fish body. The tip ends of either the brush hairs 13a, 14a and the short bristle brush hairs 13b, 14b abut. Specifically, the tip of the long bristle foot brush bristles 13a and 14a hits the thin dorsal fin and belly fin side, and the tip of the short bristle foot brush bristles 13b and 14b hits the thick central part. As a result, regardless of the size of the fish body W, the surface of the fish body can be removed uniformly over the entire surface of the fish body.

  And the fish which comes out between the brush hair tips of the rotating brushes 11 and 12 is sandwiched from the upper and lower sides by a pair of endless chains 75 and 76 of the carry-out side chain conveyor 70, and between the brush hair tips of the rotating brushes 11 and 12. It is forcibly taken out and conveyed.

  When the fish enters the horizontally opposed region E of the endless chains 75, 76, the upper arm member 79 and the lower arm member 82 are interlocked by the action of the sector gears 87, 88 according to the thickness of the fish, etc. The leg is turned against the spring force of 89. As a result, the pair of endless chains 75, 76 reliably sandwich the fish to be processed from both sides, regardless of the thickness of the fish being transported, without causing slipping or dropping. Next, it is carried out from between the brush bristles of the rotary brushes 11 and 12. In addition, this conveyance is also reliably performed in a state in which the protruding pieces C of the endless chains 75 and 76 have bitten and captured the fish body surface.

  Further, the fish transported by the carry-in side chain conveyor 40 and the carry-out side chain conveyor 70 is also prevented from falling off by being guided by the guide members 60 and 90, and the fish body is conveyed by the carry-in side chain conveyor 40 and the carry-out side chain conveyor 70. The fish will be transported reliably.

  Assume that the fish conveyance speed (chain speed) by the carry-in side chain conveyor 40 is Va, the peripheral speed of the brush bristles of the rotating brushes 11 and 12 is Vb, and the fish conveyance speed (chain speed) by the carry-out side chain conveyor 70 is Vc. Va = Vc or Va <Vc, and the peripheral velocity Vb at the tip of the bristle is set sufficiently higher than the conveying speeds Va and Vc. These speeds may be set to appropriate values according to the type and state of the fish to be transported.

  Under the reliable conveyance of the fish body, the “slimming” on the surface of the fish body is continuously scraped off by the rotating brushes 11 and 12, and the sliming is reliably and satisfactorily performed.

In addition, it is preferable that the surface of the fish body is removed by the rotating brushes 11 and 12 while the rotating brushes 11 and 12 and the fish body are wet by watering, and the slime is washed away.
In contrast, in this embodiment, water is supplied from the water supply nozzles 100 and 101 into the hub portions 11A and 12A of the rotary brushes 11 and 12, and the water is ejected by centrifugal force as the rotary brushes 11 and 12 rotate. Water spouts outward from the holes 11B and 12B. As a result, the slime can be washed away with a small amount of water.
