【Example】

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which a bivalve mollusc posture correction device according to the present invention is incorporated into a bivalve continuous feeding process will be described below with reference to FIGS. 1 to 12. In this embodiment, the bivalve posture correction device according to the present invention is applied to a scallop. First, there is a hopper 1, into which a plurality of scallops 3 are thrown. Inside the hopper 1, a first conveying/exporting means 5 is installed. This first conveyance/export means 5 includes a drive motor (not shown), a pair of rotating bodies 7.7 rotated by the drive motor, and an endless body wound and stretched around these rotating bodies 7.7. It is composed of a belt 9 and a belt 9. Among the rotary bodies 7.7, one rotary body 7 is arranged at the bottom of the hopper 1, and the other rotary body 7 is disposed above the upper edge of the hopper 1. The heald 9 is configured to rotate in the direction indicated by arrow a in the figure. Projections II are fixed to the heald 9 at a predetermined pitch. A plurality of scallops 3 placed in the hopper 1 are transported one by one from the bottom of the hopper 1 toward the upper edge by the heald 9. That is, one scallop 3 is placed between the protrusions 11 and 11 and transported. Front/back detection means 13 is installed in the middle of the transport of the first transport/export means 5. The front and back detection means 13 is, for example, an optical sensor, and is used to determine the front and back sides of the scallop 3 based on brightness. That is, the front side of the scallop 3 is brown and the back side is white, and the front and back sides are determined by detecting the difference in brightness. The scallops 3 transported to a position above the hopper 1 by the first transport/export means 5 drop onto the second transport/export means 17 via the chute 15. Shoot 15 above
A reversing means 19 is provided at the lower end position. F. As shown in FIG. 8, the reversing means 19 includes a rotary solenoid 21, a link 2; 3 fixed to the rotating shaft of the rotary solenoid 21, and a link rotatably connected to the link 23. 25, a link 27 rotatably connected to this link 25, a shaft 29 fixed to this link 27, and a baffle plate 31 fixed to this shaft 29. If it is determined by the detection by the front/back detection means 13 that the front surface of the scallop 3 is directed upward, the rotary solenoid 21 is deenergized. As a result, as shown in FIG. 9, the baffle plate 31 is retracted from the falling path of the chute 15, so that the scallops 3 remain in the second conveyance state.
It falls into the carrying out means 17. On the other hand, if it is found by detection by the front/back detection means 13 that the back side of the scallop 3 is directed upward, the rotary solenoid 21 is brought into an excited state. Thereby, as shown in Figure 10, link 2
3 to 27 are activated to cause the baffle plate 31 to protrude into the falling path of the chute 15. Due to the protrusion of the baffle plate 31, the scallops 3 falling down the chute 15 collide with the baffle plate 31, thereby causing the scallops 3 to turn over. The second transport/unloading means 17 is composed of a chute 33 and a gate means 35 installed at the end position of the chute 33. The diameter of the artificial part 37 of the chute 33 is enlarged, and a partition plate 39 is attached. In other words, the scallop 3 that has been turned over by the turning means 19 that has already been extended
falls on the left side of the partition plate 39 in FIG. 3, and the scallop 3 that is not turned over falls on the right side of the partition plate 39 in FIG. The gate means 35 has a structure as shown in FIGS. 11 and 12. First, a rotating member 41 is arranged, and a shutter 43 and a stopper 45 are fixed to this rotating member 41. The rotating member 41 has a link 4
Another link 49 is attached to the link 47 to which 7 is fixed.
A further link 51 is rotatably connected to the end of this link 49. - The link 51 is configured to rotate around a shaft 53. On the other hand, below the link 51, a chain 55, which is a conveyance/portion means to be described later, is provided so as to move in the direction shown by the arrow in the figure. It is installed protrudingly. As shown in FIGS. 11(a) and 11(b), the movement of the chain 55 causes the link 51 to rotate via the protrusion 57, thereby causing the shutter 43 to close the exit of the chute 33. . On the other hand, when the rotational bias of the link 51 by the protrusion 57 is released, as shown in FIGS. 12(a) and 12(b),
The occlusion by the shutter 43 is released, and instead the next movement of the scallop 3 is regulated by the stopper 45. Through this action, the scallops 3 are carried out one by one. In the case of this example, 60~
Scallops 3 are carried out at a rate of 200 scallops/minute. During the conveyance of the chute 33, a number detecting means 59 is installed. The number detecting means 59 is configured as an optical sensor, an ultrasonic sensor, or a mechanical sensor. The number detecting means 59 detects the number of scallops 3 stagnant in the chute 33, and controls on/off of the first conveying/exporting means 5 as appropriate. The reason for this configuration is as follows. That is, the scallops 3 in the hopper 1 are transported by the first conveying/exporting means 5.
When carrying out the scallop 3, there may be cases where the scallop 3 is not placed between the protrusions 1N and 11 (the scallop 3 falls out). is set slightly earlier. Therefore, if the scallops 3 do not come off, the chute 33 will be oversupplied with scallops 3 and stagnate. Therefore, as already mentioned, the number of stuck pieces is detected by the number detecting means 59, and the first conveying/unloading means 5 is turned on.
The scallops 3 transported by the 1 and 2nd transport/export means 17 that control the turning off are transported through the chute 60,
The bivalve posture correction device 61 according to the present invention will now be used. The configuration of this bivalve mollusk posture correction device 61 will now be explained. As shown in FIG. 2, a pair of rotating bodies 63.6:3 rotated by a driver (not shown) is arranged.
The aforementioned chain 55 is wound and stretched around these pair of rotating bodies 63, 63. The chain 55 has
A plurality of brackets 67 are attached. This bracket 67 is composed of a plate body 68 and a protrusion 69 protruding from the plate body 68, and includes a pair of adjacent brackets 67, 67 and a fixing member installed opposite to the plate body 68. The guide 68' forms a housing space 71 in which the scallop 3 is housed in a predetermined posture. The protrusion 69
is formed into a substantially triangular plate when viewed from the front. On the other hand, the elastic means 73 moves into the accommodation space 71 at a predetermined pitch.
It is located in The elastic band/stage 73 is connected to the holt 75,
It consists of a spring rod 79 connected to this port 75 via a compression coil spring tongue 77. The scallops 3 that have fallen into the accommodation space 71 are
While being transported, the spring rods 79 of the plurality of elastic means 73
collide with As a result, the posture of the scallop 3 is gradually corrected and becomes a predetermined posture. The scallop 3 that has been conveyed and corrected by the bivalve posture correction device 61 is conveyed by the third conveying and unloading means 81, and as shown in FIG.

[Effect]

First, a plurality of scallops 3 are put into the hopper 1. The loaded scallops 3 are transported one by one from the bottom to the top of the hopper 1 by the belt 9 of the first transport/export means 5. At this time, the front and back sides of the scallop 3 are detected by the front and back detection means 13. That is, it is determined whether the surface of the scallop 3 is facing upward. When the surface of the scallop 3 is facing upward, the reversing means 19 is turned off, and when the surface of the scallop 3 is not facing upward, the reversing means 19 is turned on. The scallops 3 transported by the first transport/export means 5 are
It falls through the chute 15 onto the second conveying/exporting means 17 . At this time, if the surface of the scallop 3 is facing upward, the reversing means I9 is turned off, and the scallop 3 continues to fall down the right side of the partition plate 39 in FIG. 3. On the other hand, when the surface of the scallop 3 is facing downward, the reversing means 19 is turned on and the baffle plate 31 projects into the conveyance path. When the falling scallop 3 collides with this protruding baffle plate 31, it is reversed and
It falls on the left side in the figure. This causes all the scallops 3 to have their surfaces directed upward. The scallops 3 that have fallen onto the second conveyance/export means 17 are conveyed through the chute 33, and are conveyed out one by one by the gate means 35 at the terminal position. That is,
As the chain 55 moves, the end of the chute 33 is opened or closed by the shutter 43, and the stopper 45 allows or restricts the movement of the next scallop 3. Due to this action, the scallops 3 are carried out one by one through the chute 60 onto the bivalve posture correcting device 61. The number detection means 59 measures the number of scallops 3 in front of the gate means 35 of the chute 33, and the first conveyance/export means 5 is turned on and off as appropriate based on the detected value. . This prevents excessive scallops 3 from staying in the chute 33. The scallop 3 that has fallen onto the bivalve posture correcting device 61 is not conveyed in a predetermined direction and its posture is corrected. That is, the scallops 3 carried out from the second conveying/exporting means 17 fall into the accommodation space 71 between the adjacent brackets 67, 67. Since the posture in which the scallop 3 falls into the storage space 71 is arbitrary, it is necessary to correct it to a predetermined posture. That is, as shown in FIGS. 5 and 6, while being transported, the scallop 3 collides with the spring bar 79 of the elastic means 73, thereby causing the scallop 3 to rotate in the direction shown by arrow C in the figures. By repeating this several times, the ears 3a of the scallop 3
is corrected to a predetermined posture pointing downward. In the above process, the elastic means 73 may be in a predetermined posture even before colliding with the spring rod 79. In this case, even if the scallop 3 collides with the spring bar 79 of the elastic means 7:3, it will not rotate and will be transported without kicking the spring bar 79 of the elastic means 73. be. The scallop 3, which has been transported to a predetermined location and whose posture has been corrected by the knee mollusk posture correction device 61, is transferred to the third conveyance and
It is conveyed by the carrying-out means 8I and supplied to the punching machine 84 via the conhair 82. That is, it is elastically held and conveyed by a pair of fingers 89 and 89 attached to the tip of the am 87 that rotates as the chain 85 rotates. Thereafter, a plurality of scallops 3 are continuously transported and supplied by the same action. 1. With the above configuration, when feeding the scallops 3 to the punching machine 84, the posture is unified when feeding them.
A hole can be made accurately at a predetermined position in the ear part 3a of the scallop 3. Since the ear part 3a of scallop shell 3 occupies a small space, it is difficult to mechanically drill the ear part 3a if it is not positioned accurately. Since it is fitted between the two brackets and the position is stabilized, the positioning force is possible and accurate. . In addition, since the postures of the scallops 3 are automatically unified, it is possible to automate the work of supplying the scallops 33 to the punching machine 84, thereby reducing the labor required for the work and the writing time. It is possible to shorten the time. It should be noted that the present invention is not limited to the above embodiments. For example, bivalves are not limited to scallops, but can be applied to any bivalve that can distinguish the front and back sides. In addition, the elastic means 73 is not limited to what is shown in the figure.
Elastically deformable materials such as elastic rubber or leaf springs may also be used.

【Effect of the invention】

As described in detail above, the bivalve posture correction device according to the present invention automates the feeding of bivalve mollusks to the punching machine,
It has the effect of reducing the labor required for work, shortening work time, and improving work efficiency.
