DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a continuous bivalve feeding device according to the present invention will be described below with reference to FIGS. 1 to 12. In this embodiment, the bivalve continuous feeding device according to the present invention is applied to scallops. First, there is a hopper 1, into which a plurality of scallops 3 are thrown. Inside the hopper I, a first conveyance/unloading means 5 is installed. This first conveyance/unloading means 5 includes a drive motor (not shown), a pair of rotating bodies 7.7 rotated by this drive motor, and these rotary bodies 7.
．． Of the above-mentioned rotating bodies 7.7, one of the rotating bodies 7 is arranged at the bottom of the hopper 1, and the other one is arranged at the bottom of the hopper 1. The rotating body 7 is disposed on the L side of the 1' edge of the hopper 1, and the heald 9 is configured to rotate in the direction of force shown by arrow a in the figure. Projections 11 are fixed to the heald 9 at a predetermined pitch. A plurality of scallops 3 placed in the hopper 1 are conveyed one by one from the bottom of the hopper 1 toward the -L edge by the heald 9. That is, the projection 11.1
One scallop 3 is placed per hour and transported. In the middle of the conveyance of the first conveyance/export means 5, a front/back detection means 13 is installed. 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 shell 3 is brown and the back side is white, and the front and back sides are determined by detecting the difference in brightness. The scallop 3 transported by the first transport/export means 5 to the -1- direction position of the hopper 1 is dropped into the second transport/export means 17 via the chute 15. A reversing means 19 is provided at the end position of the chute I5. 1- The reversing means 19, as shown in FIG.
A link 23 fixed to the rotating shaft of the link 2;
a link 25 rotatably connected to the link 25;
a link 27 rotatably connected to the link 27;
The shaft 29 is fixed to the shaft 29, and the baffle plate 31 is fixed to the 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 I5, so the scallops 3 remain as they are during the second conveyance.
It falls into the carrying out means 17. On the other hand, if it is found through detection by the front/back detection means I3 that the scallop 3 or its back side is directed upward, the rotary tread 7 noite 21 is brought into an excited state (1). As shown in FIG. 10, the links 233 to 27 are operated 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 scallop 3 falling through the shoe 115 collides with the baffle plate 31, thereby causing the scallop 3 to turn over. The second transport/unloading means 17 includes a chute 33, a gate means 35 installed at the end position of the chute 33, and the like. The entrance portion 37 of the chute 33 has an enlarged diameter, and a partition plate 39 is attached thereto. That is, the scallops 3 that have been inverted by the already extended inverting means 19 fall to the left side of the partition plate 39 in FIG. 3, and the scallops 3 that have not been inverted fall to the right side of the partition plate 39 in FIG. It is something. 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 A''. The rotating member 41 has a link 4
Another link 49 is rotatably connected to the fixed L'-pi link 47, and this link 49
Further, another link 51 is rotatably connected to the child end of the link. The link 51 is configured to rotate around a shaft 53. On the other hand, the F part of the link 51 is provided with a chain 55 of a conveyance/correction means, which will be described later, so as to move in the direction already indicated by the arrow in the figure.
They are protruded at specified pitches. 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 closure by the shutter 43 is released, and instead the next movement of the scallop 3 is regulated by the stopper 45. Due to this action, the scallops are transported out one by one. In the case of this example, 60
Scallops U3 are carried out at a rate of ~200 pieces/min. A first stage 59 for detecting the number of pieces is installed in the middle of the conveyance of the chute 33. 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, when the scallops 3 in the hopper 1 are carried out by the first conveyance/export means 5, there are cases where the scallops 3 are not placed between the protrusions 11 and 11 (the scallops 3 fall out). Assuming such a situation, the conveying speed of the first conveying/exporting means 5 is set to be slightly faster. For this reason, the above scallop 3
If the scallops 3 are not removed, the chute 33 will be oversupplied with scallops 3 and stagnate. Therefore, as described above, the number of stuck pieces is detected by the number detecting means 59, and the on/off of the first transport/conveyance 11 stage 5 is controlled. . Starfish 143 transported by the second transport/export means 17
is transported through the chute 60 and transported/straightened +E'L stage 61
It will fall to 1-. This conveyance/correction means 6
The configuration of 1 will 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 the 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 68 and a protrusion 69 protruding from the plate 68, and a pair of adjacent brackets 67 and 67 are installed facing the plate 68. The fixed 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 move the housing space 71 at a predetermined pitch.
It is located in Elastic lower 1st stage 7; 3 is Hole 1-75
and a spring rod 79 connected to this bolt 75 via a compression coil spring 77. The scallops 3 that have fallen into the accommodation space 71 are
The spring rods 79 of the plurality of elastic means 73 are
collide with As a result, the posture of the scallop 3 is gradually corrected and assumes a predetermined posture. Scallop 3 transported and corrected by the transport and correction means 61
is conveyed by the third conveyance/unloading means 81 and, as shown in FIG. 1, is supplied to the -6 punching machine 84 via the conhair 82. The third transport/unloading means 81 includes a driver (not shown), a pair of rotating bodies 83.83 rotated by the drive motor, and a pair of rotating bodies 83.83.
The chain 85 wound and stretched on the
an arm 87 attached at a predetermined pitch, and a pair of fingers 89 attached to the tip of this arm 87.
It consists of 89. Then, the scallop 3 that has been conveyed and straightened by the conveying and straightening means 61 is elastically held and conveyed by the pair of fingers 89 and 89. 3. 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 detection means 13 detects the front and back of the scallop shell 3. That is, it is determined whether the surface of the scallop 3 is facing north. When the surface of the scallop 3 is facing upward, the reversing means 19 is turned off, and the scallop;
If the surface is not facing upward, the reversing means 19 is turned on. The scallops 3 transported by the 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 -, the reversing means 19 is turned off, and the scallop 3 is placed on the right side of the partition plate 39 in Figure 3. go. On the other hand, when the surface of the scallop 3 is facing downward, the inversion step 19 is turned on and the baffle plate 331 projects into the conveyance path. The scallops 3 that fall onto this protruding baffle plate 31 collide with each other, causing the scallops 3 to turn around and fall on the left side of the partition plate 39 in FIG. The scallop shell 3 dropped onto the second transport/export means 17 is directed upward.
They are conveyed through the chute 33, and at the terminal position are taken out one by one by the gate means 35. 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 fifth scallop 3. Due to this action, the scallops 3 are carried out one by one through the chute 60 to the conveyance/correction means 610. The number detection means 59 measures the number of scallops 3 in front of the gate means 35 of the chute 33, and based on the detected value,
The stage 5 is turned on and off as appropriate, thereby preventing excessive scallops from stagnating in the chute 33. The scallop that fell into the conveyance/correction means 610; 3 is
Since it is not conveyed in a predetermined direction, its posture is corrected by IE. That is, the scallops 3 carried out from the second conveyance/export means 17 are placed in the accommodation space 71 between the adjacent brackets 67 and 67.
fall inside. 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, the scallop FL3 collides with the spring rod 79 of the elastic stage 73 during the conveyance, and is thereby rotated in the direction shown by arrow C in the figures. By repeating this several times, the ears of scallop;
``321'' is corrected to a predetermined posture pointing downward 1. In the above step (■-), the predetermined posture may be changed from 1↑11 when it collides with the spring bar 79 of the elastic means 73. In this case, is scallop 3 or elastic F stage 7:3 spring bar 7
Even if it collides with 9, it does not rotate and is carried as it is without kicking the spring bar 79 of the elastic step 7:3. The scallops 3 which have been transported to a predetermined location and whose posture has been corrected by the transport/straightening stage 61 are transported by the third transport/export means 81 and supplied to the punching machine 84 via the stiff hairs 82 . That is, it is elastically held and conveyed by a pair of fingers 89 and 89 attached to the tip of an arm 87 that rotates as the chain 85 rotates. Thereafter, a plurality of scallops 3 are continuously transported and supplied by the same action. According to this embodiment, the following effects can be achieved. First, it becomes possible to automate the work of supplying the scallops 3 to the punching machine 84, thereby reducing the labor required for the work and shortening the work time. When feeding the scallops 3 to the punching machine 84, they are supplied in a uniform manner, so that holes can be punched accurately in the predetermined positions of the ears 3a of the scallops ↓3. can. Since the ear part 3a of the scallop 3 has a small space, it is difficult to machine the hole if it is not positioned accurately. However, according to the bivalve continuous feeding device of the present invention, the ear part 3a or the adjacent Since it is fitted between the brackets 67 and 67 and its posture is stabilized, positioning can be done accurately. In addition, since the front and back sides of the scallops 3 and their postures are all automatically unified, the scallops 3 can be thrown into the hopper 1 casually. Next, a second embodiment will be described with reference to FIG. In this embodiment, the configuration of the reversing means 19 is changed. That is, a link 91 is rotatably connected to the link 27 of the reversing means 19 of the first embodiment. On the other hand, an air cylinder 93 is arranged, and this air cylinder 93 has a cylinder 95 and a cylinder 95.
A piston rod 97 is slidably housed within the piston rod. The above link 9 is attached to this piston rod 97.
1 is connected to the rotation rjj function. Then, by appropriately driving the air cylinder 93, the baffle plate 31 is moved into and out of the conveyance path. The rest of the configuration is the same as that of the first embodiment, and the explanation thereof will be omitted. Therefore, the same effects as in the first embodiment can be achieved. Next, a third embodiment will be described with reference to FIGS. 14 to 16. In this embodiment, the configuration of the reversing means 19 is changed, and the reversing means 19 is incorporated in the third conveying/exporting means 81. In other words, the arm 87 is rotatable with respect to the chain 85. The gear 101 is attached and the gear 101 is fixed. On the other hand, a solenoid (or air cylinder) 103 is arranged, and a rack 107 is fixed to the plunger 105 of this solenoid 103. Then, by selectively energizing the solenoid 103, the plunger 105 is caused to protrude, and the gear 10 is
1 and rack +07 are engaged. Thereby, the gear +01 or 180' is forcibly rotated, and the scallop shell 3 held by the pair of fingers 89 and 89 is reversed. 1. In this case, detection of the front and back sides of the scallop 3 is performed midway through the transport path of the third transport/export means 81. Based on the detection result, the solenoid 103 is appropriately excited. Even with such a configuration, the same effects as in each of the embodiments described above can be achieved. Further, according to this embodiment, since the scallops 3 are not caused to collide with the baffle plate 31, there is also the effect that there is no risk of damaging the scallops 3. Furthermore, the present invention is not limited to the above embodiments. For example, the two-piece dish is not limited to scallops, but can be applied to any two-piece dish whose front and back sides can be distinguished. In addition, front and back detection by the front and back detection means 1; 3, reversing means 1
The reversing operation according to No. 9 may be performed at a location other than the location shown in each embodiment in section +iii. In short,
It is sufficient if the front and back sides can be unified and fed to the punching machine. In addition, the elastic means 73 is not limited to what is shown in the drawings.
Elastically deformable materials such as elastic rubber or leaf springs may also be used.

【Effect of the invention】

As detailed above, according to the two-piece tool continuous supply device according to the present invention, the operation of supplying the two-piece tool to the punching machine can be automated,
It has the effect of reducing the labor required for work, shortening work time, and improving work efficiency.
