Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fish skewering device useful in a seafood processing plant that processes dried sardines and the like.

[Conventional technology]

Traditionally, when processing whole dried sardines, etc. at a seafood processing plant, workers manually pierce, for example, 12 sardines in a series with a skewer with a sharp tip. That's what I was doing.

[Problem that the invention seeks to solve]

However, this manual work of skewering fish has a very low efficiency, and in recent years, female workers have shunned this type of seafood processing work, resulting in many problems due to a lack of manpower.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides a fish feeding device in which a plurality of fish trays on which fish are placed one by one are attached to an endless annular chain that is driven in circulation so that they can be raised and lowered via a spindle. a skewer support section that fixes and supports the rear part of the skewer with the tip of the skewer facing the front end of the fish feeding device; a skewer feeding device that supplies skewers one by one to the skewer supporting section; and a skewer discharging device that removes the skewered skewer from the skewer support, and the fish feeding device is equipped with a guide rail that raises and lowers the fish receiver before and after skewering it, and also presses or releases the fish before and after skewering the fish in the fish receiver. The skewer feeding device is provided with a skewer reservoir and a parallel crank mechanism for grasping the skewers one by one and feeding them to the skewer supporting portion. The fish receiving plate on which the fish is placed is tilted using an eccentric wheel mechanism.

[Effect]

According to this invention, when fish are manually placed one by one in the same direction on the forward-driven fish tray, the fish are placed on the tip of the fixed skewer supported by the skewer support at the front end of the fish feeding device. The fish pierce the fish one after another, and at the same time as the fish pierce the fish, the fish receiver and the holding plate members are lowered or released, respectively, and retreated from the fish. When a predetermined number of fish are pierced onto the skewers, the fish feeding device is temporarily stopped in response to a command from the counter, and the fish receiving plate of the skewer discharging device is tilted to release the skewers from the skewer support and discharge them. After one skewer has been fed to the skewer support, the fish feeding device is activated again and this movement is repeated.

〔Example〕

Embodiments of the invention will be described based on the accompanying drawings. As shown in FIGS. 1 and 2, this fish skewering device has a plurality of L-shaped cross-sectional fish trays 1 on which fish A, for example, sardines, are placed one by one, and are installed perpendicularly to a pair of endless annular chains 2. A fish feeding device 3 is installed in series on a frame 4 with the tip of a skewer 5 facing the front end of the fish feeding device 3 in the direction of fish transfer (see arrow direction A in Figure 1). A skewer support part 6 that supports the rear end of the skewer 5 to be inserted, a fish feeding device 7 that supplies the skewers 5 one by one to the skewer support part 6, and a fish feeding device 7 that supplies the skewers 5 with a predetermined number of fish, for example, 12, from here. It consists of a combination with a skewer discharging device 8 for detachment.

As shown in FIGS. 3 and 4, the fish feeding device 3 is provided with a holding plate 10 that holds down the fish A on the fish tray 1 via a coil spring 9. The fish receiver 1 has approximately the same length as the fish A, is attached to the chain 2 via an upright support shaft 11 that can be raised and lowered, and has a compression coil spring 1 attached to the opposite side.
2, the elasticity near the chain 2 is biased, and the fish A slides into contact with the upper surface of the side U-shaped guide rail 13 attached along the chain 2, and is temporarily separated from the chain 2. Immediately after being stuck on the skewer 5, the guide rail 13 disappears, so the elasticity of the compressed coil spring 12 causes the chain 2 to approach the chain 2 and fall rapidly (see arrow direction B in FIG. 3) and retreat from the skewer 5.

The guide rail 13 serves to separate the fish tray 1 from the chain 2 until just before the fish is skewered, and in the upper position where the fish A is manually placed on the fish pan 1, the guide rail 13 is a thick horizontal guide rail. 14.

The presser plate 10 has two upright bars 15 on the frame 4.
A block 16 is attached to this upright rod 15 so as to be able to move up and down, and is fixed to the tips of two horizontal arms 17 that are attached to this block 16 so as to be able to slide in the horizontal direction. The elasticity close to the block 16 is biased by the restoring elasticity. Further, the holding plate 10 is raised and lowered by a crank mechanism 18 attached to the end face of the block 16. The circular motion of the presser plate 10 is controlled by the coil spring 9, as shown in the direction of the arrow C in FIG.
6, descends using a crank mechanism 18 to abut the fish, moves forward while holding down the fish A as the fish receiver 1 moves forward, and immediately after skewering rises due to the operation of the crank mechanism 18 and retreats from the fish. Note that 36 is a drive section of the fish feeding device, and a drive section (not shown) of the crank mechanism 18 is provided separately.

As shown in FIGS. 5 to 7, the skewer support section 6 includes a two-part elastic chuck 20 having an opening 19 at the top, and a horizontal skewer 5 held by the chuck 20, which is repositioned for centering. Rack 21 for pairs
It consists of a centering part 23 of a pinion 22, and when the skewer 5 is pushed into the chuck 20 through the opening 19, the skewer is grabbed by its elasticity, and when pulled out with force, the skewer comes off. By rotating the upright pinion 22, the chuck 20 is caused to move slightly in the longitudinal direction.

As shown in FIGS. 2 and 5, the skewer feeding device 7 includes equal-length links 25 facing left and right, equal-length links 26 facing forward and backward in the plane of the drawing, and auxiliary links attached below them in a staggered manner. 26a, and one link 25 is fixed to an upright column 27, applying a parallel crank mechanism.A skewer clip 28 is attached to the lower end of the movable link 25, and is supported by the skewer support part 6. When the skewer 5 runs out, the switch is automatically turned on and the parallel crank mechanism is driven by the drive unit 30 to grip the center of the skewer 5 in the skewer reservoir 29 with the clip 28 (see Fig. 1) and support the skewer. 6 (see arrow direction D in FIG. 5). In addition, 24 is a stopper, and 3
0 is a drive unit equipped with a cam that drives the skewer feeding device at appropriate times. The skewer storage part 29 is a plate-shaped part made of an inclined surface, and allows the skewers to roll one by one under their own weight.

As shown in FIG. 8, the skewer discharging device 8 comprises an eccentric wheel 32 and a swing rod 3, each having a rectangular fish catch plate 31 with a smooth upper surface and having a length substantially the same as the entire length of the skewer 5.
3 (see arrow direction H in FIG. 8), the skewered fish on the fish receiving plate 31 slides down and is collected on the pair of receiving rods 34. Fish catch plate 31 is pin 3
5 is a fulcrum, and the fish A being skewered on the upper surface thereof slides sequentially while being pierced by the skewer 5.

FIGS. 9 and 10 show examples of gill stabbing. In the case of gill stabbing, fish feeding device 3
A short guide rail 38 with a slope 37 is provided on the top surface of one of the pair of guide rails 14 on which the fish receiver 1 slides.
The tip of the fish head on the fish receiver 1 is this guide rail 38
The skewer 5 advances while coming into contact with the skewer, and the skewer 5 comes to pierce the gill part which bends and opens just before skewering.

FIG. 11 and FIG. 12 show an embodiment of eye pricking. Since there is no need to bend the head in the case of fish head stabbing, in order to eliminate the slope of the guide rail 38, a contact plate 39 is attached here with screws so that the surface on which the tip of the fish head comes into contact is flat. In addition,
By removing this plate, you can easily change it to gill stabbing.

When using the fish skewering device according to the present invention, the fish A are sequentially placed in the same direction on the fish tray 1 which is manually advanced by an operator. At this time, fish A is placed with its head down and its back up, and the fish head is made to protrude from the fish receiver 1 (see Figure 9). This makes skewering easier, and the head is secured by the protruding part of the gills. bends evenly.

This fish skewering device also includes a counter for the number of fish to be pierced on one skewer, a command to stop the fish feeding device 3 and the fish holding plate 10, a command to stop the skewer feeding device 7,
Commands to stop the skewer discharge device 8 are automatically issued by various internal electrical devices, and the skewer reservoir 29 has a funnel-shaped skewer receiving section (not shown), in which a large number of skewers can be placed. When the skewers are inserted, the skewers automatically fall one by one into the skewer reservoir 29.

〔effect〕

As described above, the fish skewering device according to the present invention can automatically skewer fish, such as sardines, by simply manually placing them one by one on the fish tray. Since the skewers are skewered sequentially, the tips of the skewers do not swing and can be skewered accurately without damaging the fish body. Furthermore, since the driving force for transporting the fish is used for skewering, the device can be operated efficiently.

Furthermore, this fish skewering device has the advantage that it is possible to easily select eye skewering or gill skewering by attaching and detaching the contact plate of the fish feeding device.
