Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fish pricking device that is useful in fish processing plants that process dried sardines and the like.

[Conventional technology]

Traditionally, when processing whole dried sardines at a seafood processing plant, a worker would manually pierce a series of 12 sardines with the stick using a needle with a sharp tip. I was doing it.

[Problem that the invention seeks to solve]

However, this manual fish-eye stabbing work has a very low efficiency, and in recent years, female workers have shunned this type of seafood processing work, resulting in problems such as a lack of manpower.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a fish holding member that holds fish lined up one by one and a corrugated fish receiving slope plate that feeds fish with their heads downward. a support part, a stabbing rod firing device that pierces the eyes of a plurality of fish supported by the fish support part in a series from orthogonal directions, a water current device that flows water on a fish receiving inclined plate of the fish support part and pushes the fish away; The fish support part is formed of a switch, etc., and the fish support part is provided with a locking rod that lowers and locks the fish when skewered, and the holding member is composed of a fixed plate and a fish clamping plate that reciprocates laterally. A flat L-shaped jig of a size corresponding to the size of the fish is attached to the pinching plate, and the lower end of the fish receiving inclined plate swings downward to release a series of fish after being skewered. The firing device consists of a stinging rod reservoir section that stores a large number of stinging rods and loads the stinging rods one by one into the firing section from the lower end, and a firing section that pushes the rear end of the loaded stinging rods to make the stinging rods fly out. The water flow device is composed of a water discharge pipe installed on the upper edge of the fish receiving inclined plate, a gutter for collecting flowing water, and a circulation pump.

[Effect]

According to this invention, when fish are inserted and fed into the fish support part one by one with their heads facing downwards (at this time, their backs are facing upwards), the fish are swept away by the water current and are placed at the lower end of the fish receiving slope plate. When the fish is lined up against the clamping member and the operation switch is pressed, the fish clamping plate first moves and clamps the fish with the clamping member, at the same time raising the tilted fish on its back, and then the lowered locking rod holds the fish. In this state, the fish's eye is stabbed with a stick sticking out from the perpendicular direction, and finally the lower end of the fish receiving inclined plate swings downward and the skewer separates from the clamping member and the locking rod. Fish in this state will fall due to flowing water and their own weight.

〔Example〕

Embodiments of the invention will be described based on the accompanying drawings. In the fish pricking device of the present invention, a corrugated fish receiving slope plate 2 is attached to a holding member 1 fixed to a frame that holds fish A arranged in parallel, such as sardines, one by one. a fish support part 3, a firing device 5 for a stabbing rod 4 that successively pierces the eyes of a plurality of fish A supported by the fish support part 3 from the side in an orthogonal direction;
It consists of a water flow device 6 (see FIG. 2) that flows water on the inclined plate 2 of the fish support section 3 to push the fish away, an operation switch 7 (see FIG. 1), and the like.

The fish support section 3 has a horizontal plate 1 which is attached to a portal frame 9 projecting from the front end of the work table 8 so as to be movable up and down, in order to temporarily hold the fish A during skewering.
0, a large number of vertical locking rods 11 are arranged downward in parallel.

As shown in FIG. 6, the clamping member 1 consists of a flat fixing plate 12 and a flat L-shaped fish clamping plate 13 that reciprocates from side to side.A fish A is inserted between the two, and the fish clamps A flat L-shaped jig 14 (see FIG. 7) of a size corresponding to the size of the fish is attached to the grinding board 13.

As shown in FIG.
It is fixed to the frame via the frame and placed on the flat plate 16 at the lower end of the inclined plate 2 (see FIGS. 4 and 12), and is attached to a horizontal rotation shaft 17 disposed at the bottom of the work table 8. A certain plate cam 18 causes the fish clamp plate 13 to move laterally via the central support shaft 15 to widen the gap, and when the plate cam 18 raises the spring 19, the fish clamp plate 13 is attached to the outside of the fish clamp plate 13. The fish clamping plate 13 returns to the fixing plate 1 due to the restoring force of the coil spring 20.
2 will make the fish A softer.

In addition, the jig 14 is attached so that the stinging rod 4 pushed out from the stinging rod firing device 5 just passes through the eye of the fish A, and as shown in FIG. A plurality of grooves 21 for inserting the cutting board are provided, and the thickness t ₁ of the short horizontal board 22 having an L-shaped planar shape and the thickness t ₂ of the long vertical board 23 from the inner surface of the groove 21 are varied. Make and prepare the fish and replace as appropriate depending on the size of the fish in each lot. Of course, the fish to be stabbed should be of approximately the same size within the lot.

The fish receiving inclined plate 2 is supported by a workbench middle plate 25 so as to be able to swing downward via a horizontal shaft 24 (see FIG. 12) on the back surface of the approximately central portion, and is attached to a horizontal rotating shaft 17. Via the lever 27 that engages with the cam 26, it swings downward intermittently, forming a steep slope (see Figure 5 D and Figure 12), and the series of fish A after being skewered fall off from the holding member 1, falling into running water and It comes to be released onto the guide rod 49 due to its own weight.

The lower end of the locking rod 11 is supported by a transparent plate 28 provided with a small hole, and is raised vertically by an electromagnetic device 29 at the top. It descends due to the restoring force of a certain coil spring 30 and gently holds and locks the fish A.

This locking rod 11 is lowered to a position biased toward the fixing plate 12 at the neck of the fish A in the gap between the fixing plate 12 of the holding member 1 holding the fish A and the fish holding plate 13. , since it descends to the side of the hard neck, it does not damage the fish body and serves to straighten the tilted fish body so that its back is upward. The electromagnetic device 29 is the plate cam 1
After the fish clamping plate 13 of the clamping member 1 is operated by the limit switch 31 engaged with the clamping member 1, the locking rod 11 is lowered at a good timing. Note that the locking rod 11 can be expanded and contracted via a joint 50 in the middle.

As shown in FIG. 9, the stinging rod firing device 5 includes a stinging rod storage box 32 that stores a large number of stinging rods 4 horizontally in a bundle and discharges the stinging rods one by one from the lower end;
It consists of a cylinder 35 located below this storage box 32, which has horizontal grooves 33 of equal pitch on its circumference and rotates intermittently to supply one by one to a firing part 34 below, and a firing part 34. As shown in FIG. 11, the cylinder 35 is intermittently rotated via a lever 37 which is oscillated by a plate cam 36 attached to the horizontal rotating shaft 17.

Further, the ejection part 34 is constructed by attaching two protrusions 40 to a chain 39 that is rotated by a pair of chain wheels 38. Become. The chain wheel 38 is rotated by a motor 41 via a transmission device. It should be noted that the firing section can also use another mechanism such as an air cylinder.

As shown in FIGS. 2 and 12, the water flow device 6 includes a water discharge pipe 42 piped to the upper edge of the fish receiving inclined plate 2, an upper gutter 43 for collecting flowing water, middle gutter 44, 45, and Lower gutter 46, water collection pipe 47 that collects water from each gutter, and circulation pump (not shown)
The water discharge pipe 42 is connected to a water pipe 48 connected to a circulation pump. The water discharged from the water discharge pipe 42 flows down on the fish receiving inclined plate 2 and serves to smoothly push the fish A on the corrugated plate into the holding member 1 without damaging them.

The operation switch 7 is installed in a conspicuous position close to the operator who inserts fish into the fish receiving inclined plate 2, and the operator inserts the required number of fish to be skewered, for example, 12, into the fish receiving inclined plate 2. Then, press the ON button to activate each part of the machine, and when one skewer is completed, the machine will automatically stop. Note that the OF button is for pausing.

In the fish pricking device, the fish may be supplied to the work table 8 by a conveyor, and the fish are simply inserted one by one into the fish receiving inclined plate 2 by hand, which is the conventional method for all operations. This will greatly improve efficiency compared to when it was done manually.

〔effect〕

As described above, the fish pricking device according to the present invention can greatly improve efficiency compared to the conventional manual work performed by female workers, and can alleviate the labor shortage in fish processing work. can be resolved. In addition, even if the size of the fish changes from lot to lot, this fish eye pricking device allows you to accurately penetrate the fish eye simply by changing the jig, and even though it is a mechanical device, it does not take into account water flow or the restoring force of the spring. It has the effect of not causing any damage to the fish body when used.
