Japanese Patent Laid-Open No. 10-304834

  However, in the conventional sheet-like laver adsorption mechanism, one end of the adsorption head is pivotally supported on the substrate by a single spindle, and the adsorption head rotates by an angle around the spindle to suck and separate the sheet-like laver. Therefore, the suction head itself is not maintained in a state parallel to the opening, and thereby the suction force due to the negative pressure of the blower is not uniform, and the sheet-like laver may not be reliably sucked and separated. .

  Therefore, the present invention was created in view of the existing circumstances as described above, and the adsorbing pad is maintained in a state parallel to the opening for taking out the sheet-like nori from the nori hopper. By making it possible to adsorb and separate the sheet, the suction force due to the negative pressure of the blower is made uniform so that the sheet-like nori can be reliably adsorbed and separated, and the adsorbed and separated sheet-like nori is reliably transferred to the supply position. An object of the present invention is to provide a sheet-like laver adsorption mechanism for an automated laver winding apparatus capable of performing the above.

  In order to solve the above-mentioned problems, in the present invention, the inside of the laver hopper is cut to a required size in advance with a blower type adsorption pad that moves in the contact and separation direction with respect to the opening for taking out the sheet-like laver from the laver hopper. The sheet-like seaweed is taken out one by one, and this is fed to the feeding part side of the formed cooked rice with a feeding mechanism, and the suction pad arranged on the opening part side is attached to the opening part. In order to make it possible to adsorb and separate sheet-like seaweed while maintaining the parallel state, a pair of synchronously rotatable support shafts connected to a rotation drive source and one end fixed to one support shaft and the other end to one One swivel link arm pivotally attached to one end of the suction pad adjacent to the other support shaft, one end fixed to the other support shaft, and the other end of the suction pad adjacent to the other support shaft The other swivel pivotally attached to the end Link is constituted by an arm, but with a four-bar parallel link mechanism formed by the pivotable parallel to each other with the turning link arm.

  The suction pad is formed by forming a cavity formed by sucking air from the intake port of the base through the suction pad by a blower and branching it toward the opening side of the laver hopper so as to adsorb the sheet-like seaweed. Can be.

  The suction pad is provided with a substantially L-shaped suction port cover on the opening edge side of the cavity so that the suction port of the base is always closed while maintaining communication with the cavity throughout the swivel movement range of the suction pad. It can consist of

  The feeding mechanism is located near the position of the suction pad that has moved away so as to sandwich one end of the sheet-like seaweed adsorbed by the suction pad at the position where the suction pad has moved away from the opening of the nori hopper by the four-bar parallel link mechanism It may be arranged in

  The feed mechanism is disposed so as to be opposed to the drive roller connected to the rotation drive source so as to be able to come into contact with and away from the drive roller, and to swing back and forth via a support shaft connected to the rotation drive source. And a driven roller pivotally attached to the moving arm.

  The suction pad can be configured to be detachable from the swivel link arm.

  The adsorption pad can be configured to adsorb the smooth surface side of the sheet-like seaweed.

  In the sheet-like laver adsorption mechanism of the laver winding apparatus according to the present invention configured as described above, the adsorption pad that moves in the contact / separation direction with respect to the opening for taking out the sheet-like nori of the nori hopper is a four-node parallel link When the suction pad approaches the opening due to the swing movement of the pair of swing link arms of the mechanism, air is sucked from the suction port of the base through the suction pad cavity by the blower, and the sheet-like seaweed is absorbed by the suction pad. .

  Further, when the suction pad moves away from the opening of the laver hopper by the four-bar parallel link mechanism, one end of the sheet-like seaweed that is attracted to the suction pad is received by the drive roller, At the same time, the driven roller is rotated to the driving roller side through the swinging arm and brought into pressure contact, and one end of the sheet-like seaweed is sandwiched between the driving roller and the driven roller, and then the driving roller is rotationally driven to remove the sheet-like seaweed. Supply to the supply side of the shaped cooked rice.

  The intake port cover always closes the intake port of the base while maintaining communication with the cavity over the swivel movement range of the suction pad, and prevents leakage of suction air from the intake port.

  According to the present invention, it is possible to easily adsorb and separate the sheet-like seaweed while maintaining the adsorption pad in a parallel state with respect to the opening for taking out the sheet-like seaweed of the seaweed hopper. The suction force due to the pressure is made uniform, and the sheet-like nori can be reliably adsorbed and separated, and the adsorbed and separated sheet-like nori can be reliably transferred to the supply position.

The sheet-like nori can be easily adsorbed and separated while maintaining the parallel state, and the sheet-like nori can be stably supplied to the forming mechanism.

  The suction pad is formed by forming a cavity formed by sucking air from the intake port of the base through the suction pad by a blower and branching it toward the opening side of the laver hopper so as to adsorb the sheet-like seaweed. Therefore, the suction force due to the negative pressure of the blower can be made uniform, and the sheet-like nori can be reliably adsorbed and separated.

  The suction pad is provided with a substantially L-shaped suction port cover on the opening edge side of the cavity so that the suction port of the base is always closed while maintaining communication with the cavity throughout the swivel movement range of the suction pad. Therefore, it is possible to prevent the suction air from leaking from the intake port, and to suppress the attenuation of the suction force due to the negative pressure of the blower.

  The feed mechanism is located near the position of the suction pad that has moved away so as to sandwich one end of the sheet-like seaweed adsorbed by the suction pad at the position where the suction pad has moved away from the opening of the nori hopper by the four-bar parallel link mechanism Since the sheet-like seaweed adsorbed by the adsorbing pad and the sheet-like nori detachment from the adsorbing pad by the feeding mechanism can be performed intermittently without interfering with each other, the molded rice supply unit Can be reliably transported to the side.

  The feed mechanism is disposed so as to be opposed to the drive roller connected to the rotation drive source so as to be able to come into contact with and away from the drive roller, and to swing back and forth via a support shaft connected to the rotation drive source. It is provided with a driven roller pivotally attached to the moving arm, so that one end of the sheet-like seaweed adsorbed to the adsorbing pad by both rollers can be securely sandwiched, and the supply of shaped cooked rice The conveyance to the part side can be performed smoothly.

  Since the suction pad can be attached to and detached from the revolving link arm, the suction pad can be easily cleaned and becomes hygienic.

  Since the adsorbent pad adsorbs the smooth surface side of the sheet-shaped nori, the scattering of nori dregs can be reduced.
