Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for arranging fish, butterflies, etc. in the same direction.

(Prior Art and its Problems) In general, natural foods vary in shape and size, making it difficult to standardize their handling during processing and processing steps.

For example, in the processing of fish, there is a step of aligning the heads before processing, and the aligning machine shown in FIG. 1 has conventionally been used.

This device is intended for lining up large fish such as mackerel, and a wire mesh b is fixed to the bottom of a pedestal a, slides c and c fixed at both ends are inserted through guide rods d, and appropriate This is an alignment machine in which a pedestal a is driven to reciprocate from side to side along a guide rod d.

When a fish is dropped into the center of the pedestal a during reciprocating movement using a gutter e, etc., the mesh catches gills and scales,
Because fish are slimy and have bullet-shaped heads, they move forward in the direction their heads point without resistance, but do not move forward in the direction their tails point. Move forward only in the right or left direction you are facing.

Therefore, guiding troughs (not shown) are placed at both ends to guide the fish along the curved path shown by the dashed line.

With this conventional sorting machine, when a large number of fish are dropped onto the pedestal, the pedestal simply slides from side to side in a horizontal position, so fish facing the opposite direction will be on top of the moving fish, facing toward the edge. Also, because the guide gutter is bent, the fish collide with each other and end up facing the opposite direction, making it impossible to align all the fish in the same direction during processing, so the orientation of the fish must be corrected manually. was necessary.

In addition, with this sorting machine, small fish such as sardines cannot be lined up well because the gills are weakly caught, and furthermore, when the fish loses freshness, the slime disappears, causing trouble in sorting.

Also, by adopting the same principle, we published Japanese Patent Application Publication No. 48-38297
The device No. 1 has been proposed. This device consists of a multistage continuous arrangement of a fish reservoir that vibrates from side to side, a sorting conveyor, and a discharge conveyor, and when fish facing different directions are dropped from the front and back of the sorting conveyor, fish facing backwards pass through a reversing chute that reverses. , the fish are ejected in two lines facing forward.

However, this device is designed on the assumption that it is not possible to line up all the fish in the same direction on the sorting conveyor, and the fish that pass through the reversing chute fall onto the sorting conveyor that vibrates from side to side. A reliable reversal cannot be expected due to differences in size or timing.

(Technical Problem) The present invention is an apparatus in which a receiving frame on which a wire mesh is stretched is vibrated, and fish, etc. that have fallen onto the frame are arranged and discharged. The challenge was to align them.

(Technical means) The technical means for solving this technical problem are: (a) The front part of the receiving frame is supported by the machine base via a link rod, and (b) The rear part is rotated by a drive means. This is to support the shaft body.

(Effect of technical means) The rear part of the receiving frame performs circular motion in a direction perpendicular to the longitudinal direction, but since the front part of the receiving frame is supported by the machine base via a link rod, the receiving frame moves in the vertical direction. Then, a complex rocking movement is performed in the front and rear directions, and a phenomenon occurs in which the entire receiving frame is lifted up.

Therefore, a fish that falls onto the wire mesh fixed to the receiving frame will be thrown back and forth once due to the compound movement of the receiving frame, but a fish with its head facing the front side will be caught when the wire mesh moves toward the front side. The opening edge on the rear side of the mesh hole catches scales and fins, and the bullet-shaped head of the fish and the slimy surface cause the fish to intermittently move over the wire mesh toward the front. They move forward and are sent out from the front side of the receiving frame with their heads aligned.

Fish that turn sideways or backwards are pushed back by the front opening edge of the hole providing resistance to the scales and fins as the wire mesh moves toward the rear, and the intermittent combined movement of the wire mesh. While dancing on the wire mesh, the animal gradually turns its head forward and is sent forward on the wire mesh in the same manner as described above.

Incidentally, even if a fish lands on top of a fish that has fallen onto the wire mesh, this is a temporary phenomenon and can be easily resolved by the combined movement of the receiving frame.

Therefore, the fish are lined up in the same direction on the same wire mesh and discharged.

In the case of foods whose ends are caught on the opening edge of the mesh hole, such as Stribeans (ingen beans) or double-cut butterburs, the direction of revolution of the revolving axis that is supported by the receiving frame is reversed, and the receiving frame is rotated. These foods are fed from the front side of the receiving frame, with the direction facing the rear side.

As a result, the ends of the food items will be caught in the mesh and will be advanced vertically toward the rear side of the receiving frame. Items lying sideways on the wire mesh will try to roll down to the front side of the wire mesh, but due to the difference in thickness and slight deformation at both ends, they will not roll down while rolling on the wire mesh. They will gradually be aligned in the vertical direction.

Therefore, by changing the shaking direction (shaking direction) depending on the shape of the food, it is possible to accurately align the food on the same wire mesh.

(Effects of the present invention) As a result of being able to discharge fish etc. on the same surface and in the same direction, the discharge route is unified and it becomes possible to connect directly to the subsequent process, thereby reducing the work in the subsequent process of processing. This has the advantage of being extremely efficient, and the device itself can be made compact and the work space can be used effectively.

A technique for arranging fish using the mesh by swinging the surface of the wire mesh is disclosed in Japanese Patent Application Laid-open No. 123899/1983. However, the net surface of this device uses a simple rocking system in which the left and right side edges are moved up and down, and the fish take advantage of their body shape to turn sideways during the rocking, and the fish face at right angles to the rocking direction. The product is discharged in two directions, and is not configured to be directly connected to subsequent processes.

(Embodiment) A crank or eccentric mechanism may be used to drive the revolution shaft supported at the rear of the receiving frame.

The length of the link rod and the mounting position between the receiving frame and the machine base can be configured to be constant. This keeps the movement of the receiving frame constant at all times, which is sufficient if the same product, for example sardines, is to be lined up continuously.

If the mounting position of the drive means such as a link rod, crank or eccentric mechanism, and the support frame and/or machine base can be changed, the locus of the swing motion of the support frame can be changed, for example, the support point of the support frame can be changed. By moving it to the front part, the swing width of the front end of the receiving frame can be reduced.

The locus of the swing motion of the receiving frame can also be changed by making the length of the link rod adjustable.

The wire mesh stretched over the receiving frame is preferably a mesh with as little unevenness as possible, and a punched wire mesh formed by punching holes in a metal plate is suitable.

The movement of the receiving frame and the shape of the mesh holes should be determined by taking into account the type and properties of the workpiece, the desired alignment speed, etc.
The choice will be decided.

(Example) Next, a specific example of the above technical means will be described with reference to the drawings.

FIRST EMBODIMENT FIG. 2 shows a partially cutaway right side view of the alignment machine. A machine base 1 is formed by appropriately combining frames 2, and above it a receiving frame 11 is slightly slanted forward. It is placed in the state of.

A rotating shaft 4 supported by bearings 3, 3 fixed to the rear upper surface of the machine base 1 passes through and is fixed to eccentric wheels 12, 12, which have an outer ring 13 wrapped around the bottom of a receiving frame 11 with a metal fitting 14. The rotation of the motor 6 is received by a pulley 5 fixed to a rotating shaft 4, so that the rear part of the receiving frame 11 rotates.

A pair of left and right link rods 15 are arranged at the front lower part of the receiving frame 11, and their upper ends are pinned to the bottom of the receiving frame 11, and their lower ends are pinned to the machine frame 2, respectively.

Side walls 16, 16 are attached to the left and right side edges of the receiving frame 11, and a punched wire mesh 17 shown in FIG. The fish are guided to fall onto the wire mesh 17.

As shown in FIG. 6, a flow rate adjustment plate 22 is attached to the front part of the receiving frame 11 so as to be able to swing left and right on a wire mesh 17, and the flow rate adjustment plate 22 can be adjusted to adjust the amount of fish supplied corresponding to two post-processes with different processing capacities. (It goes without saying that this flow rate adjustment plate is unnecessary if there is only one post-process).

The size, shape, and density of the punched holes 18 in the wire mesh 17 need to be changed depending on the type, size, shape, etc. of the workpiece. This is because the hooking action of the rear opening edge 19 of the hole 18 based on the compound movement of the wire mesh 17 urges the workpiece to move forward in the forward direction.
The purpose is to prevent the workpiece from moving forward in the opposite direction. Small circular holes are good for Ingen beans, but they cannot promote forward movement for fish, and as shown in Figure 5, the holes are
It is best to have an opening edge perpendicular to the direction of travel.

It goes without saying that the size of the hole must also be considered so that the workpiece does not fall through the punched hole.

In the above embodiment, an eccentric mechanism was used, but as shown in FIG.
4 and 24 may be used.

Second Embodiment The second embodiment has a configuration in which the attachment position of the link rod can be changed. FIG. A link rod 33 with pins 34, 34 protruding from the upper and lower ends of the plate is provided so that the pin insertion hole can be selected.

FIG. 9 also shows that the rails 35, 35 are attached to the front part of the receiving frame 11 and the frame 2, and the link rod 37 is
It is configured so that pins 38, 38 protruding from the upper and lower ends of the stopper 3 slide.
By fixing the position of the pin 38 using the pins 9 and 40, the attachment position of the link rod 37 can be changed.

Regarding the telescopic structure of the link rod, a known telescopic structure such as forming the link rod with an inner cylinder and an outer cylinder, and selecting the length by inserting pins or bolts into the inner and outer cylinders at desired positions, should be adopted. Good.
