Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fish body transfer device used in a fish processing plant or the like for dividing fish bodies, particularly frozen fish bodies, into small pieces along the spine.

Conventionally, as a fish transport device, two sets of feed rollers shaped to fit the fish body are arranged symmetrically on the left and right sides of the fish transport line, and are linked by an interlocking member.
The two sets of feed rollers are pressed against the fish body by a pressure means and rotated in conjunction with each other in the feeding direction, and the feed roller shafts are provided in front and behind the two sets of feed rollers. A pair of auxiliary feed rollers are provided supported by a pair of swinging arms that oscillate around the center, and these auxiliary feed rollers are pressed against the fish body by pressure means and rotated in synchronization with the feed rollers. During feeding and unfeeding, the fish body is pinched by two sets of auxiliary feed rollers and feed rollers, so that slippage of the feed rollers does not occur even in the case of frozen fish bodies, and the fish body is pinched by the two sets of feed rollers. When this is done, a symmetrical motion of the feed roller with respect to the fish body transfer line is used so that the body axis of the fish body between the pinching parts always coincides with the fish body transfer line. Even when transporting frozen fish that are approximately the same thickness in the middle and suddenly become thinner at the head and tail,
Fish bodies are pulled in and pulled out automatically, and no human assistance is required. Therefore, fish bodies can be transferred by the fish supply staff alone without fatigue, and the transfer state is controlled by the feeding rollers. Because the body axis line and the transfer line match between the pinched areas,
If a processing tool such as a band saw is provided between the pinched parts, it is possible to reliably split the fish body into left and right halves along the body axis. However, the aforementioned two sets of feed rollers and auxiliary rollers are provided at the same height above the table, and when viewed from the side, the fish are transported straight. Therefore, when a fish body is cut into two parts vertically using a horizontal saw, the fish body 1 is cut straight as shown in Figure 1, but the spine a of the fish body is curved as shown in the figure. Because of this, the part of the fish meat indicated by b in the figure is lost, which reduces the meat yield. Therefore, the horizontal saw is raised and lowered according to the curvature of the spine, and the fish body is divided into upper and lower halves according to the curvature of the spine. A device was proposed, but this device has a complicated structure and is expensive, and it is difficult to time the lifting and lowering of the fish body transfer device and the horizontal saw, and if the timing is out of order, the meat harvesting yield will deteriorate. It was hot.

The device related to the present invention is intended to completely eliminate the above-mentioned problems by creating a height difference between two sets of feed rollers and an auxiliary feed roller, and moving the fish body in a curve that matches the curve of the fish's spine. It is.

In the apparatus configured as described above, a band saw 6 is placed between the auxiliary feed rollers 16, 16 at the front and the feed rollers 10, 10 to cut the fish body 1 with the head and tail into two vertically. If the small bones are aligned and fed from the caudal side, the fish body 1 will move the steeply sloped part of the caudal side to the feeding roller 1.
0 and 10, and at the same time, the intermediate portion of approximately the same thickness is also sandwiched between the auxiliary feed rollers 16, 16, and receives the transfer force of the rollers 10, 10 and 16, 16 at two locations. Since no slip occurs between the fish body and the rollers, the fish body 1 automatically moves to the rollers 10 and 10.
10 and 16, 16, the fish body 1 is tilted forward and downward due to the height difference between the auxiliary feed rollers 16, 16 and the feed rollers 10, 10, and is transferred toward the band saws 9 and 6. 10, 10 and 10',

0' and the auxiliary feed rollers 16', 16', the rollers 10', 10' and 16',
Due to the height difference with 16', the fish 1 will move further forward and upward, and the transport state seen from the side of the fish 1 will be a curved transport that matches the curvature of its spine a. It is cut into two parts at the top and bottom at part a.

Moreover, the above-mentioned feed rollers 10, 10 and 10',
10' means interlocking members 13, 13 and 13', 13'
Due to the interlocking action with the fish body transfer line In order to position the body so that it coincides with The deviation between the body axis and the fish body transfer line XX is determined by the front and rear feed rollers 10, 1.
This is not a problem unless the distance between 0 and 10', 10' is large, and if the fish body 1 is curved,
Due to the symmetrical movement of 0' and 10', figures 6 to 8 of the drawing
As shown in the figure, the direction of the fish body 1 is corrected and the body axis, that is, the midbone part, is automatically aligned with the band saw, so that even the curved fish body 1 can be placed on the band saw 6 at the position of the dorsal ossicles.
As a result, it will be divided into two parts, left and right.

As the fish body 1 is divided into quarters in this way, the head side end of the fish body 1 comes off the front feed rollers 10, 10, but at this time, the rear auxiliary feed roller 1
6' and 16' pinch the middle part of the fish body 1 with almost the same thickness, and the rear feed 1 pinches the steep slope on the head side of the fish body 1.
In cooperation with 0' and 10', a transfer force is applied to the fish body 1,
Fish bodies are also automatically pulled out to prevent slips.

In addition, the auxiliary feed rollers 16, 16 in this device
and 16', 16' are feed rollers 10, 10 and 1
0' and 10' as described above to ensure automatic transfer of the fish body 1, but each has an independent swinging arm 18,
18, 18', 18', and pressurizing means 1
9 and 19, when the feed rollers 10, 10 and 10', 10' perform the deflection operation of the fish 1, the fish body 1 is
According to the deviation of
It moves as shown in FIGS. 1 and 10, and reliably performs the feeding assisting action without interfering with the deflection action of the fish body 1.

The device related to the present invention has two parts that are shaped to fit the fish body.
Sets of feed rollers are arranged symmetrically on the left and right sides of the fish transfer line, and are supported by two sets of swinging arms linked by an interlocking member, and these two sets of feed rollers are moved by a pressure means. The rollers are pressed against the fish body and rotated in conjunction with each other in the feeding direction, and furthermore, a pair of auxiliary feed rollers are provided in front and behind the two sets of feed rollers, supported by a pair of swinging arms that swing around the feed roller shaft. , etc. By using a configuration in which the auxiliary feed roller is pressed against the fish body by a pressure means and rotated in synchronization with the feed roller, the fish body is also fed and sent out by pinching the fish body with two sets of the auxiliary feed roller and the feed roller,
Even in the case of a frozen fish, the feed roller should not slip. When a fish is pinched between two sets of feed rollers, the feed rollers should move symmetrically with respect to the fish transfer line to ensure smooth movement between the pinched areas. When transporting frozen fish, the body axis of the fish is always aligned with the fish transfer line, so the middle part is almost the same thickness, and the head and tail sides are suddenly thinner. However, since the pulling in and out of fish bodies is done automatically and does not require human assistance, fish supply personnel can transfer fish bodies alone without fatigue, and the transfer state is controlled by feeding rollers. Since the body axis line and the transfer line coincide between the pinching areas, if a processing tool such as a horizontal or vertical band saw is installed between the pinching areas, the fish body can be moved left and right along the body axis regardless of its curve. Not only can it be split into two parts, but the front and rear feed rollers and auxiliary feed rollers have a height difference, and this difference in height allows the fish to be transported in a curve that matches the curved line of the backbone. It has the unique effect of making it possible to cut the meat into upper and lower halves with almost no loss, thereby significantly improving the meat yield.
