[Action]

First, in the case of the bivalve drilling device according to the first claim,
The bivalve is loaded into the bivalve carrier from a predetermined position. Since the endless body of the bivalve conveying means rotates in one direction, the bivalve is carried into any bivalve holding part of the plurality of bivalve holding parts. For this loading, the loading direction of bivalves does not matter. The bivalve that has been carried into any bivalve holding portion is conveyed in one direction as it is while being guided by the guide means. On the other hand, since the endless body of the bivalve posture correcting means is rotating in the other direction and acts to bias the bivalve held in the bivalve holding portion in the other direction, the bivalve is an endless body of the bivalve conveying means. Is urged to rotate in the same direction as the rotating direction of.
Therefore, even if the bivalve is carried in in an arbitrary direction, the rotation of the bivalve will correct its posture to a predetermined posture. The bivalve mollusc that has been conveyed to a predetermined position in a state where it is corrected to a predetermined posture is then punched in the ear portion by a punching machine. The bivalve that has been made a hole is further transported by the bivalve transporting means, and then unloaded. In the case of the bivalve piercing device according to the second aspect,
The endless body of the bivalve transport means and the bivalve posture correcting means rotate the endless body in the same direction, thereby rotating the bivalve in the other direction while abutting the bivalve holding portion to correct the posture. Is. When tilting each part including the device body by α °,
The bivalves are transported with being inclined by α °. As a result, the bivalve will come into contact with the endless bodies of the guide means and the bivalve posture correcting means with sufficient contact resistance, thereby preventing the bivalve from slipping during the posture correcting action of the bivalve posture correcting means. Therefore, the posture of the bivalve can be surely corrected within a limited distance. Further, even when the entire apparatus is inclined upward by β ° in the carry-out direction, sufficient contact resistance can be generated to prevent the bivalve from slipping.

【Example】

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. First, there is an apparatus main body 1, and the apparatus main body 1 is constructed by assembling various steel materials (for example, angle materials). Further, as shown in FIG. 3, the apparatus body 1 is fixed in a state of being inclined by α ° (45 ° in the case of this embodiment) with respect to the horizontal plane. The reason why the apparatus body 1 is inclined in this way will be described later. A scallop transfer means 3 is attached to the apparatus body 1. That is, the drive motor 5 is arranged, and the drive sprocket 7 is fixed to the rotary shaft of the drive motor 5. A driven sprocket 9 is arranged separately from the drive sprocket 7 and
A roller chain 11 as an endless pair is rotatably wound around the driven sprocket 9. A plurality of scallop shell holders 13 are attached to the roller chain 11 at a predetermined pitch. As shown in FIGS. 2 to 5, the scallop holding portion 13 is fixed to the roller chain 11 and has a horizontal member 14 protruding up to the belt 31 in a direction orthogonal to the rotation direction of the roller chain. , A vertical member 16 erected from the horizontal member 14,
It is composed of an inclination member 15 provided at those corners. Then, the scallops 19 loaded one by one from the scallop loading unit 17 are loaded and held in an arbitrary scallop holding unit 13 among the plurality of scallop holding units 13. The scallops 19 thrown in and held in an arbitrary scallop shell holding portion 13 are sequentially conveyed to the right in the drawing as the roller chain 11 rotates clockwise in FIG. Will be carried out more. Further, as shown in FIGS. 1 to 3, the apparatus body 1 is provided with a scallop posture correcting means 23 at a position facing the scallop feeding means 3. That is, the drive motor 25 is arranged, and the drive pulley 27 is fixed to the rotation shaft of the drive motor 25. On the other hand, a driven pulley 29 is arranged, and these drive pulley 27 and driven pulley 29 are arranged.
A belt 31 as an endless body is wound around. The belt 31 rotates in the opposite direction (counterclockwise in FIG. 2) to the roller chain 11 of the scallop transfer means 3 already described. That is, by rotating the belt 31 in the opposite direction with respect to the roller chain 11, the scallop 19 held by the scallop holding portion 13 is biased to correct its posture. This will be described in detail with reference to FIGS. 2 to 4. For example, it is assumed that the scallop 19 is carried in in the state shown at the left end in FIG. In this state, the roller chain 11 rotates clockwise in the figure, so that the scallops 19 are sequentially conveyed in the right direction in the figure. On the other hand, since the belt 31 is rotating counterclockwise in the figure and the belt 31 contacts the lower end of the scallop 19, the scallop 19 is rotationally biased in the clockwise direction in the figure. Thereby, the posture of the scallop 19 is gradually corrected, and the ears 20 thereof are corrected to a predetermined posture in which the ears 20 are directed downward. Further, when the scallop 19 is corrected to a predetermined posture, the ear 20 contacts the inclined portion 15 of the scallop holding portion 13 as shown in FIG. 4, so that further rotation is restricted. In addition, from the time of loading, if it is loaded in a predetermined posture,
Since the rotation is restricted from the beginning, it is transported as it is. A punching machine 33 is installed in front of the carry-out section 21. The punching machine 33 is composed of a drill portion 37 for making a hole having a predetermined diameter at a predetermined position of the ear portion 20 of the scallop 19, and a scallop fixing portion 39 for pressing and holding the scallop 19. Then, the scallop shell 19 that has been transported to a predetermined position by the scallop shell transporting means 3 is pressed and fixed by the scallop shell fixing portion 39, and in that state, the drill portion 37 is used for perforation. A positioning sensor 41 is installed at a position facing the punching machine 33. The positioning sensor 41 is specifically a limit switch. The positioning sensor 41 detects that the scallop 19 has reached a predetermined drilling position,
The punching machine 33 is activated. The pierce portion of the scallop 19 is preferably 4 mm horizontally from the contact point between the ear 20 and the inclined portion 15 and 4 mm above the contact point with the belt 31, as shown in FIG. Is the position. By setting such a position, it is possible to surely make a hole regardless of the size of the scallop 19. That is, as shown in FIG. 5, the positioning sensor 41 includes a retractable member 42 and a roller 44 rotatably attached to the retractable member 42. Then, by rotating the roller chain 11, the horizontal member of the scallop shell holding portion 13
When 14 hits the roller 44, the retractable member 42 is urged substantially upward in the drawing. On the other hand, when the horizontal member 14 of the scallop holder 13 passes, the protruding / retracting member 42 is allowed to project. With such an operation, the position of the scallop shell holder 13, that is, the position of the scallop shell 19 is detected, and the operation of the scallop shell transport means 3 and the operation of the punching machine 33 are controlled. Guide members 43, 45 are installed on both sides of the roller chain 11 of the scallop carrier means 3 to guide the scallop 19 to be transported. At the punching position, a part of the guide member 45 is cut out so that the punching operation by the punching cut 33 is allowed. The rotating operation of the roller chain 11 of the scallop transfer means 3 is a constant intermittent operation, and the operation of the punching machine 33 is also a constant intermittent operation. Then, the scallops 19 are conveyed by a predetermined pitch by the intermittent rotation motion of the roller chain 11, and when the scallops 19 are conveyed to the perforation position, the perforator 33 operates so as to be synchronized with the perforation position. In this case, the belt 31 may rotate at all times, or may rotate intermittently in synchronization with the roller chain 11. In the former, scallop 19
Is forcibly fixed by the scallop fixing part 39 at the time of perforation, and therefore slips on the belt 31. Therefore, the belt 31 may be damaged or worn by the scallop 19. The latter is desirable because it can prevent this. By the way, the main purpose is to incline the device body 1 by 45 °. This is because the scallop 19 is brought into contact with the belt 31 of the scallop posture correcting means 23 and the guide member 43 with appropriate contact resistance. This is because the slip of 19 is prevented and the rotation for posture correction is made smooth. Incidentally, if the scallop 19 is not tilted, it is necessary to sandwich the scallop 19 from both sides in order to obtain the required contact resistance, and at that time, the force of sandwiching must be adjusted depending on the size of the scallop 19. Become. The operation will be described based on the above configuration. First, the scallops 19 are loaded one by one through the loading unit 17. On the other hand, the roller chain of the scallop transfer means 3
11 is rotating clockwise in FIG. 2, and the belt 31 of the scallop position correcting means 23 is rotating counterclockwise in FIG. The scallops 19 carried in are sequentially put and held in an arbitrary scallop shell holder 13 among the plurality of scallop shell holders 13 that are rotating. The scallops 19 loaded and held in the scallop shell holding portion 13 are conveyed by a predetermined pitch by the intermittent rotation motion of the roller chain 11. This will be described in more detail. Scallop transfer means 3
Turning on / off of the drive motor 5 is forced by the positioning sensor 41. When the retractable member 42 of the positioning sensor 41 is urged by the horizontal member 14 of the scallop holder 13, the drive motor 5 is turned off, and is turned on after the set time has elapsed. That is, ON / OFF is repeated according to the pitch of the scallop shell holder 13. At that time, the scallop is corrected to a predetermined posture by the action of the belt 31 of the scallop posture correcting means 23. That is, when the scallops are conveyed in one direction by the scallops conveying means 3, the belt 31 of the scallops posture correcting means 23 imparts posture correction force, and as a result, the posture of the scallops 19 is gradually corrected to a predetermined posture. To go. Then, when transported to the punching position, the punching operation by the punching machine 33 is performed. That is, by the action of the positioning sensor 41, the drive motor 5 of the scallop carrier means 3 is turned off, and at the same time, the punching machine 33 is turned on to perform a predetermined punching operation. As a result, the scallop shell 19 having a hole of a predetermined diameter drilled in the ear portion 20 is further transported by the scallop shell transporting means 3 and is delivered via the unloading portion 21. Hereinafter, by repeating the same operation, a predetermined number of scallops 19 are perforated. As described above, according to this embodiment, the following effects can be obtained. First of all, it is possible to carry in any direction without paying attention to the loading direction of the scallops 19, and it is possible to automate all the punching work on the scallops 19, so that the work efficiency can be greatly improved, Work safety can be improved. Since the scallop 19 is perforated after being corrected to a predetermined posture, the quality of perforation is constant, and no special skill is required for the operator who handles the device. In the case of this embodiment, the entire apparatus 1 including the apparatus body 1 is
Since the scallops 19 are tilted at 45 ° and the scallops 19 are tilted at 45 °, they are conveyed.
Due to the relationship with the belt 31 of 23, the scallop 19 can be smoothly rotated for the posture correction. Therefore, the posture can be surely corrected within a limited distance. Next, a second embodiment will be described with reference to FIG. In this case, the scallop shell conveying means 3 of the first embodiment is the scallop shell posture correcting means, and the scallop shell posture correcting means 23 is the scallop shell conveying means. In other words, the scallops 19 are conveyed by the belt 31, and at that time, the scallops 19 are brought into contact with the scallop shell holding portion 13 and rotated in the other direction to correct the posture thereof. The present invention is not limited to the above-mentioned one embodiment. First, although the scallop was shown as an example in the above-mentioned one embodiment, it can be applied to various other bivalves. Also, the inclination angle of the device is not limited to 45 °,
It can be set to any inclination angle. Of course, the thing which does not make it incline is also contained in this invention. Regarding the on / off control of the drive motor 5, a pulse generator is attached to the output shaft of the drive motor 5 in order to handle high-speed processing, and the feed amount is calculated and controlled by the number of pulses. Good. In addition, the configuration of each part is not limited to that shown in the drawings, and for example, when the entire apparatus is carried out in the carry-out direction by β ° (for example,
It is conceivable to make an upward slope of only 7 °). Also in this case, there is an effect of preventing the scallop 19 from slipping.

As described above in detail, according to the bivalve piercing device of the present invention, the piercing work can be automated, so that the work efficiency and the work stability can be improved, and The quality can be kept constant. Also, by inclining by α °, it is possible to prevent the bivalve from slipping during posture correction and provide a smooth correction motion.
