  While receiving the seaweed from the front by a pair of left and right seaweed receiving seats, and prepared in a biased state to press from behind by a seaweed pressing roller fitted into the seaweed storage tray,

  First, the laver is first driven by an output shaft of a reversible motor for driving a rotating arm that projects from the installation box and has a base end of a horizontal rotating arm that lies horizontally at a position immediately before the laver storage tray. , By moving the back of the laver by a certain angle, sucking out the eccentric position on the corresponding feeding direction side of the laver one by one by the air sucking force of the laver sucking pad attached to the tip of the rotating arm,

  Subsequently, the laver in the process of being pulled out and separated by the backward movement of the pivoting arm is bent and deformed by a laver bending guide rising from the middle part of the laver storage tray,

  Similarly, when the pivoting arm reaches the return end point, by releasing the air suction force of the nori pad, the laver is restored to its expanded form, and bent from the nori feeding direction side of the nori storage tray. It will project to the outside laterally by a certain length almost corresponding to the deformed amount,

  Control is performed to rotate the reversible motor for driving the rotating arm based on an output signal from a sensor that detects that the protruding seaweed has been artificially picked and lost.

  Further, in claim 2 subordinate to claim 1, the laver sowing pad that protrudes backward and integrally from the middle part of the rotating arm is moved in the same way as the laver of the rotating arm during the backward movement of the rotating arm. It is characterized in that the laver is distorted and deformed like a whisper by being pressed against the laver earlier than the sucking pad.

  On the other hand, in claim 3, as a device used for carrying out the laver feeding method, the top surface of the tabletop installation box is configured to be in a downwardly inclined posture state at a certain angle via a pair of front and rear hinges and a bottom support rod. Nori storage tray supported by

  While being interposed between the left and right of both receiving seats, in a position that has been retracted a certain distance forward from these, nori flexion guide that also stood up from the front end of the laver storage tray,

  A laver pressing roller that is fitted into the laver storage tray so as to freely roll and is used to push forward the laver from the rear, based on the forward and downward tilted state of the tray,

  Horizontally mounted to the position just before the laver storage tray, with the base end as the center of rotation, the laver comes into contact with the laver by an output shaft that protrudes from the reversible drive motor stored and installed in the installation box. A revolving arm that is reciprocated by a certain angle in the forward and backward direction,

  A nori pad that is attached and integrated backward to the tip of the rotating arm corresponding to the feeding direction side of the laver, and

  An air suction path for connecting the vacuum pump stored and installed in the installation box and the nori suction pad of the rotating arm;

  For an air suction hose which is located immediately before the tip of the rotating arm and is integrally suspended from an installation box and has an air vent hole which is formed to open forward in communication with the middle of the air suction path. An attendant,

  An on-off valve that is suspended in a pendulum manner from the front of the relay stand, and that keeps the air vent hole sealed at all times by its own gravity;

  In order to open the air vent hole of the relay stand, it comprises a pressing screw rod protruding rearward and integrally located corresponding to the opening / closing valve from the tip of the rotating arm,

  During the return movement of the swivel arm, the laver sucked from the tray is pulled forward and separated by the laver sucker pad of the swivel arm that has moved backward in contact with the laver in the laver storage tray. , Bent and deformed with the seaweed bending guide as a fulcrum,

  As soon as the reversing end point of the pivot arm, the pressing screw 杆 presses the open / close valve, and as soon as the air release hole is opened, the seaweed released from the seaweed sucking pad is restored to the unfolded form, In addition, it will protrude from the feeding direction side of the laver storage tray to the lateral outward side by a certain length substantially corresponding to the amount of bending deformation,

  It is set that the laver feeding detection sensor that detects the fixed portion of the fixed length is set to control the reversing motor for rotating the arm every time it detects that the laver is lost. Features.

  Further, in claim 4 subordinate to claim 3, a nori sear pad that can intervene between the nori receiving seat located on the side opposite to the nori feeding direction side and the nori flexure guide is provided in the middle of the rotating arm. Projecting from the back in one piece,

  The seaweed spreading pad is pushed to the seaweed earlier than the seaweed pad of the rotating arm that intervenes between the seaweed receiving seat located on the seaweed feeding direction side and the seaweed bending guide, and the seaweed is followed by It is characterized by the fact that it is set so as to be distorted and deformed like that.

  In claim 5 which is also dependent on claim 3, the air vent hole opening / closing valve is suspended by a hinge attached to the top surface of the air suction hose relay stand,

  The weight attached to the lower end of the opening / closing valve is extended and extended from the relay stand by a certain length in the lateral direction, and the weight extension surface is set to be pressed by the pressing screw 突出 protruding from the tip of the rotating arm. It is characterized by that.

  In claim 6, which is also dependent on claim 3, by wrapping the brake shoe around the output shaft of the reversible motor for rotating arm which projects from the top surface of the installation box and hangs up so that the strength of the braking force can be adjusted. It is set to relieve the pressure shock of the sucking pad against the seaweed.

  In claim 7, which is also dependent on claim 3, a plurality of parallel rolling guide rails extending in the front-rear direction from the bottom surface of the laver storage tray are projected, and the heavy laver is pressed against the rolling guide rails. While the roller can be inserted and removed from above,

  The bottom support rod of the laver storage tray was periodically lifted and lowered by a reversing motor for lifting operation stored and installed in the installation box, so that a positive rolling shock was applied to the laver pressing roller. It is characterized by that.

  In claim 8 that is also dependent on claim 3, the laver sucking pad of the rotating arm and the vacuum pump are connected in communication by a plurality of parallel air suction paths.

  According to the above configuration of claim 1, the laver sucked by the laver sucking pad of the rotating arm is pulled out from the laver storage tray and separated in the process of returning to the front of the rotating arm, Since it is bent and deformed by the laver bending guide that stands up from the tray, when the suction force is released for a certain length substantially corresponding to the amount pulled into the bent deformation state, the laver storage tray is fed in the feeding direction side. It will protrude from the side to the outside.

  As a result, the overgrown portion of the seaweed can be used as a picking allowance, and the sushi cooker can surely pick it up quickly without causing the problems of the prior art described at the beginning. When the seaweed is no longer picked up, the reversing motor for rotating arm is rotated by the output signal from the seaweed feeding detection sensor that detects this, and the nori of the seaweed by the reciprocating motion of the rotating arm is rotated. Since the feeding action is performed by itself, it is extremely convenient as an automatic feeding method for laver.

  In particular, if the configuration of claim 2 is adopted, the nori padding in the middle part presses the nori in front of the nori blotting pad attached to the tip of the rotating arm, and the storage that follows the nori Since the seaweed in the tray is unraveled and deformed as if it is crawl, each piece of seaweed can be accurately sucked by the following nori pad, and there is no risk of mistakes in the feeding action of the seaweed.

  According to the configuration of claim 3, as a device for carrying out the laver feeding method, all the necessary members such as the laver storage tray, the rotating arm, and the relay table for the air suction hose are mounted on the desktop installation box. In addition, the reversible motor for driving the rotating arm, the vacuum pump, and the reversible motor for raising and lowering the bottom support rod of the laver storage tray can be stored and installed inside the installation box. As a laver feeding device, there is an effect that it can be conveniently installed and used on a cooking table such as a sushi restaurant.

  If the configuration of claim 4 is adopted, the eccentric position occupying the side opposite to the feeding direction side of the laver is first distorted and deformed by the laver spreading pad of the rotating arm, and the subsequent laver in the laver storage tray Each piece of seaweed that has been sown can be reliably sucked out of the eccentric position on the feeding direction side by the laver sucking pad of the subsequent rotating arm, and the stability and reliability of the laver feeding action is remarkably improved.

  If the structure of Claim 5 is employ | adopted, the air extraction hole can be always urged | biased by the gravity of the weight attached to an on-off valve, and a pressing screw rod for opening this can be always sealed. There is also the convenience that the operating length can be adjusted by moving the arm back and forth as a literal screw rod.

  If the structure of Claim 6 is employ | adopted, the rotational speed of a rotation arm will be braked appropriately, and the nori sucking pad may press the nori too much strongly, and the nori retreat or the mistake of the sucking may be ensured. Can be prevented.

  Furthermore, if the structure of Claim 7 is employ | adopted, the nori in a laver storage tray can be squeezed forward by giving a positive rolling shock to a laver press roller, and between the adjacent laver This has the effect of preventing the possibility of the occurrence of uneven gaps and the inadvertent depression.

  If the configuration of claim 8 is adopted, the laver sucking pad of the rotating arm is connected to the vacuum pump through a plurality of air suction paths. The sucking pad can be used for sucking without mistakes, which also contributes to the reliability of the laver feeding action.

  1 to 18 showing the entire seaweed feeding device, (B) is a tabletop assembled from a stainless steel plate or other metal plate into a rectangular parallelepiped. This is an installation box of the type, for example, installed on a cooking table of a sushi restaurant. (1) is an inverted U-shaped box body, and (2) is a detachable bottom lid.

  (T) is a laver storage tray that extends a predetermined length (L1) along the front-rear direction (longitudinal direction) of the installation box (B), and includes a pair of left and right side surfaces (3) and a bottom surface (4). Is shaped into a U-shape in front view with a constant groove width (W1), and has a predetermined width for so-called warship roll (A) sushi as illustrated in FIGS. (W2) An aligned bundle in a posture in which strip-shaped laver (M) cut into a length (L2) (about 150-160 mm) and a length (L2) (about 150-160 mm) is erected by a certain amount (for example, about 300). Can be stored as. The groove width (W1) of the tray (T) is substantially the same as the width (W2) of the laver (M).

  Such strip-shaped laver (M) is quickly wound one by one by a chef's advanced technique on a so-called shari ball (sushi sushi lump) of a certain size that has been mechanically prepared separately. The sea urchin, salmon roe, and other topping materials (5) will continue to be added to the sushi of Gunkan Maki (A).

  (6) is a rolling guide rail for a plurality of laver pressing rollers that integrally rise from the bottom surface (4) of the laver storage tray (T), and is in the front-rear direction (longitudinal direction) of the tray (T). A concave groove (8) that extends in parallel and that correspondingly sinks from the circumferential surface of the laver pressing roller (7) is fitted in and used freely from above, so that it does not swing as much as possible. It has become.

  Finally, the laver pressing roller (7) has a constant length substantially equal to the width (W2) of the laver (M) as shown in FIGS. Based on the posture state, the laver (M) stored as an aligned bundle in the tray (T) is pushed forward from behind by rolling on its own along the rolling guide rail (6). It is something to be made.

  Accordingly, as long as the laver pressing roller (7) is a heavy object capable of applying a pressing force to the laver (M), for example, a stainless steel round bar or a round tube may be adopted, but the illustrated embodiment Then, while molding from polyacetal resin (preferably trade name: Duracon) and other hard synthetic resins, a heavy core rod (9) such as steel and a light core rod (10) such as polystyrene foam are formed in the hollow interior. It is embedded and integrated in a pair of left and right parallel states.

  In addition, when such a laver pressing roller (7) is fitted into the rolling guide rail (6) of the laver storage tray (T) and used, the heavy core rod (9) feeds the laver (M), which will be described later. The rolling guide rail (6) has a plurality of strips on the laver storage tray (T) along the longitudinal center line (O-O) so that the rolling guide rail (6) has a directivity that is necessarily arranged to the side (left side as viewed from the front in the figure). ) With respect to the left and right asymmetric arrangement.

  That is, the laver (M) stored as an aligned bundle in the laver storage tray (T) is transferred from the tray (T) to either the left or right side (left side as viewed from the front in the figure), as will be described later. The laver (M) is fed out one by one, but when the laver (M) in the feeding direction is eccentrically pressed from the front by the laver sucking pad of the rotating arm, which will be described later, the soaking action is stable and reliable. Therefore, a counter force that withstands the retreat of the seaweed (M) is added to one side (left side) of the corresponding position of the seaweed pressing roller (7) by the heavy core rod (9). .

  However, if such a purpose can be achieved, the burying of the light core rod (10) may be omitted, and a rolling guide rail having an asymmetrical arrangement state may be further added.

  The front end of the laver storage tray (T) having the predetermined length (L1) is projected as a bottom extension piece (4a) partially longer than the left and right side faces (3). The piece (4a) is supported in a state where it floats from the top surface of the installation box (B) via the hinge (H) to the front base plate (11) fixedly installed on the top surface of the installation box (B). ing. (12) is a horizontal pivot that connects a substantially horizontal blade plate piece (13) and a vertical blade plate piece (14) of the hinge (H), and the laver storage tray (T ) Can act as shown in FIG.

  (15) is a plurality of fixing screws for fastening the horizontal blade plate (13) of the hinge (H) and the bottom extension piece (4a) of the laver storage tray (T), and (16) is a hinge (H ) Are a pair of left and right long screw rods that fasten the vertical blade plate piece (14) to the base board (11). The laver storage tray (T) can be detached from the installation box (B) and disassembled. (17) is a fixing nut of the screw rod (16). Therefore, it is convenient for cleaning work and replacement work of the laver storage tray (T).

  Further, (18) is a pair of left and right side struts standing upright integrally from the bottom extension piece (4a) of the laver storage tray (T), and a stacked tandem state in which an idler partition collar (19) is interposed between each pair. In addition, a plurality (three in the illustrated example) of laver-receiving rollers (20a) and (20b) that are freely fitted and pivotally mounted are stored in the laver storage tray (T) as an aligned bundle in a standing posture. The left and right ends of the seaweed (M) are received from the front.

  Further, as is apparent from FIGS. 3 and 5 and FIGS. 11 to 13, among the laver receiving rollers (20 a) and (20 b) arranged in parallel as a pair of left and right, the laver (M) feeding direction side (from the front in the drawing) One laver catching roller (20a) located on the left side when viewed from the front end corner of the laver storage tray (T) faces a laver sucking pad of a rotating arm described later. Can be reliably pulled out and separated without the resistance of the receiving roller (20a).

  In contrast, the other nori receiving roller (20b) on the other side (also on the right side when viewed from the front) has a certain distance (X1) from the corner of the front edge of the nori storage tray (T). The other end (right side) of the laver (M) that faces the longitudinal center line (OO) side (inner side) and is deformed by being pressed by a laver spreading pad of a rotating arm described later is deformed. The seaweed storage tray (T) is stably received so as not to be removed from the front.

  (21) is a separate intermediate strut that stands up integrally from the bottom extension piece (4a) of the laver storage tray (T), and a plurality of laver bending guide rollers (22) are also stacked in a tandem state. In addition, it is pivotably fitted and freely fitted.

  In this case, as is apparent from FIGS. 3, 5, 7, and 8, the laver bending guide roller (22) on the intermediate strut (21) is more forward than the left and right pair of the laver receiving rollers (20a) and (20b). The laver (M) in a ready state, which is in a position retracted by a certain fixed distance (Y) and received by the both receiving rollers (20a) and (20b), is not yet in contact.

  Moreover, the laver bending guide roller (22) is eccentric from the longitudinal center line (OO) of the laver storage tray (T) by a certain distance (X2) from the laver (M) feeding direction side (left side). It comes into contact with the laver (M) in the process of being pulled forward and separated by the laver sucking pad of the rotating arm, which will be described later. Thus, the seaweed (M) can be bent smoothly by itself.

  In any case, the laver catching rollers (20a) and (20b) and the laver bending guide roller (22) are stacked as a plurality of stacked beaded states, respectively, to the corresponding side struts (18) and intermediate struts (21). Since it is fitted so as to roll freely, the seaweed (M) is only in line contact, and there is no possibility of giving excessive resistance to the feeding action of the seaweed (M).

  However, as long as the pair of left and right nori catching rollers (20a) and (20b) can function as a nori catching seat in the nori storage tray (T), a free ball or a fixed state can be used instead of the freely rolling roller. A conical protrusion or the like may be employed. As for the laver bending guide roller (22) in the middle part, as long as it functions as a bending guide for the laver (M), it is possible to adopt a fixed cylinder instead of the free-rolling roller.

  On the other hand, (23) is coupled with a hinge (H) that supports the front end portion of the laver storage tray (T), in order to keep the tray (T) in a forward downward inclined posture state of a certain angle (α), Similarly, it is a bottom support rod that receives the vicinity of the rear end of the tray (T), and vertically penetrates the top surface of the installation box (B). (24) is a bearing sleeve of the bottom support rod (23), and is fitted and fixed to the top surface of the installation box (B).

  (25) is a reversible motor for raising and lowering the bottom support rod installed horizontally in the box (B) via a hanger bracket (26) that hangs down integrally from the top surface of the installation box (B). The lifting arm (28) integrally extending and extending from the horizontal rotation output shaft (27) is engaged with the lower end of the bottom support rod (23), and the laver storage tray (T) The bottom support rod (23) can be moved up and down.

  In other words, a certain amount of laver (M) stored as an aligned bundle in a standing posture is placed in the laver storage tray (T) in the inclined state of the above-mentioned predetermined angle (α). Even if the pressing force of (7) is received, if the amount of the laver (M) is reduced when the laver feeding action from the front gradually decreases in the stationary state, there is a variation gap between the neighboring laver (M). Even if the seaweed (M) does not fall down, there is a risk of causing a feeding error, which becomes more noticeable as the constant angle (α) becomes gentler.

  As a preventive measure, every time the laver (M) is fed out one by one or intermittently every time a suitable plurality of pieces such as three are fed out, the lifting arm (28) of the reversible motor (25) The bottom support rod (23) of the laver storage tray (T) is moved up and down as shown in FIG. 14 to give a shock that the laver pressing roller (7) rolls positively, It is surely pressed from the rear and packed in an orderly manner.

  (29) is an upper limit restricting stopper which is integrally extended from the hanger bracket (26) of the reversible motor (25) for raising and lowering the bottom support rod, and the raising and lowering arm (28) of the output shaft (27). The upper limit of the bottom support rod (23) is defined by receiving it. (30) is a cushioning material such as rubber, and is backed and integrated with the bottom surface (4) of the laver storage tray (T) to relieve shock when rising in the tray (T).

  As a precaution, if the fixed angle (α) of the laver storage tray (T) is steeper than about 20 degrees, the aligned laver (M) stored in the laver storage tray (T) also has a corresponding steep angle. As a result of the inclined posture, it is difficult to confront the state of contact with the laver sucking pad and the laver sowing pad of the rotating arm, which will be described later, and the pressing force of the laver pressing roller (7) is too strong. M) is a resistance to smoothly feeding out.

  However, if the constant angle (α) is a gentler angle than about 5 degrees, when the laver storage tray (T) is moved up and down, the laver pressing roller (7) rolls backward. The seaweed storage tray used within a numerical range of about 5 to 20 degrees because there is a risk that the seaweed (M) cannot be effectively squeezed forward and the seaweed (M) may overturn. It is preferable that (T) is periodically lifted and lowered by the bottom support rod (23).

  In addition, the code | symbol (31) of FIGS. 6-8 is a cushion material which absorbs the shock at the time of the fall in the said laver storage tray (T), The back end part of the bottom face (4), and the top face of an installation box (B) A compression coil spring or rubber interposed between the upper and lower sides.

  Next, (32) is a horizontal rotating arm that lies horizontally in front of the laver storage tray (T), and its one end side (right side as viewed from the front in the figure) is the base end, The output shaft (34) that is suspended from the reversible drive motor (33) is fitted to and integrated with a thin head. The reversible motor (33) for driving the rotating arm is in a fixed storage state that hangs down from the top surface of the installation box (B) via the motor mounting flange (35), and only the output shaft (34) is installed in the installation box. It penetrates the top surface of (B).

  Similarly, (36) is a relational state in which the nori (M) in the laver storage tray (T) can be opposed to the rear surface of the tip of the rotating arm (32) on the side of feeding (M) of the laver (M). The seaweed sucker pad is affixed to and integrated with an air suction path (37) made of an elastic material such as rubber or sponge and perforated at the tip of the rotating arm (32). It is connected to an air suction port (not shown) of the vacuum pump (41) via an air suction path such as a three-air suction hose (38) (39) (40).

  Moreover, the rotating arm (32) has the output shaft (34) of the reversible motor (33) as the rotation center (P) and the laver (M) in the laver storage tray (T) as shown in FIGS. When the laver sucking pad (36) is moved backward in contact with the seaweed sucking pad (36), the laver feeding guide roller (22) and the laver receiving roller (20a) located on the feeding direction side (left side) of the laver (M) ) And interfacing with the laver (M), the eccentric position of the laver (M) can be absorbed. (R1) indicates the turning radius of the nori pad (36) in the turning arm (32).

  The vacuum pump (41) is also fixedly installed in the stowed state on the bottom cover (2) of the installation box (B), so that the bottom support rod (23) of the laver storage tray (T) is moved up and down. Like the reversible motor (25) to be driven and the reversible motor (33) to drive the rotating arm (32), there is no possibility of being exposed to cooking water. The air discharge hose of the vacuum pump (41) is led out from the installation box (B), but is not shown.

  (42) is a horizontal screw leg that protrudes backward and integrally from the middle part of the rotating arm (32), and the nori padding seat (43) at the protruding tip (rear end) has a rubber seat (43). A seaweed pad (44) made of an elastic material such as a sponge or sponge is pasted and integrated in a state where it can face the seaweed (M) in the seaweed storage tray (T).

  Moreover, the rotating arm (32) uses the output shaft (34) of the driving reversible motor (33) as the rotation center (P), and the laver in the laver storage tray (T) as shown in FIGS. M) the nori seaweed padding pad (44) when it is moved backward in contact with M), and the nori receiving roller located on the opposite side (right side) of the laver bending guide roller (22) (20b), more preferably intervening between the nori receiving roller (20b) on the opposite side and the longitudinal center line (OO) of the laver storage tray (T), and the above The eccentric position of the seaweed (M) can be pressed by making surface contact with the seaweed (M) slightly earlier than the seaweed blotting pad (36) at the tip.

  That is, the eccentric position of the laver (M) on the opposite side (right side) to the laver feeding direction side is preliminarily pressed by the laver sowing pad (44), and as a result, the laver (M) is deformed and deformed. The eccentric position on the feeding direction side (left side) is set so as to be sucked back by the laver sucking pad (36).

  In that case, about the speed with which the seaweed sowing pad (44) acts earlier than the seaweed sucking pad (36), the screw leg (42) is moved forward and backward from the rotating arm (32). It can be adjusted appropriately. (45) indicates a fixing nut of the screw leg (42), and (R2) indicates a turning radius of a nori pad (44) attached to the turning arm (32). ) Is shorter than the turning radius (R1).

  (S) is a L-shaped stopper support base in side view, and the horizontal floor piece (46) is placed at the top of the installation box (B) in a state of being parallel to the position just before the motor mounting flange (35). It is fixed to the surface. Similarly, (47) is a state in which a vertical wall piece (48) of the stopper support (S) is passed through, and a horizontal rotation angle restriction that is screwed and fastened from the front to the rotation arm (32). It is a stopper and receives the front surface of the rotating arm (32).

  In addition, when the rotating arm (32) is viewed from above as shown in FIG. 5 and FIGS. 11 to 13, the output shaft (34) of the driving reversible motor (33) is used as the rotation center (P). From a position at which the nori pad (36) at the tip can face the laver (M) in the laver storage tray (T) substantially parallel to the surface and can be received by the rotation angle restricting stopper (47) Is reciprocated in the front-rear direction by a certain angle (β) (for example, about 25 to 35 degrees), and the certain angle (β) is appropriately adjusted by the advance / retreat operation of the restriction stopper (47). It can also be adjusted. (49) is a fixing nut of the restriction stopper (47).

  Further, (50) suppresses the rotational speed of the reversible motor (33) for driving the rotating arm, and alleviates a sudden pressure shock of the padding (44) and the sucking pad (36) especially against the further laver (M). A pair of left and right brake shoes wound around a thick neck portion of the output shaft (34), which is made of a belt material such as leather or felt and whose both ends are separated as shown in FIG. 3 and FIGS. Are attached to the brake screws ５１ (51a) (51b).

  Moreover, both the brake screws 51a and 51b are screwed and fastened to the vertical wall piece 48 of the stopper support base S in the horizontal penetrating state. Thus, the braking force of the output shaft (34) can be adjusted. (52) is a nut for fixing the one brake screw 杆 (51b), and (53) is a compression coil spring wound around the other brake screw 杆 (51a). Therefore, one brake screw 杆 (51b) is positioned. By adjusting the remaining braking screw rod (51a) only against the compression coil spring (53) while maintaining the fixed state, the adjustment operation of the braking force can be performed conveniently.

  Furthermore, (C) is vertically suspended from the top surface of the installation box (B) taller than the rotating arm (32) at a position immediately before the vicinity of the tip of the rotating arm (32). An air suction hose relay stand, in which an approximately L-shaped air suction branch (54) serving as an air suction path is perforated.

  One end of the air suction branch (54) is connected to the air suction path (37) opened at the tip of the rotating arm (32) via the first air suction hose (38). Similarly, the other end of the air suction branch (54) is connected to the air suction port of the vacuum pump (41) via the second and third air suction hoses (39) and (40).

  (55) is a joint stand having communication holes for the second and third air suction hoses (39) and (40), and is located next to the motor mounting flange (35) on the top surface of the installation box (B) ( It is integrally suspended from the right side in the figure, and the rotary arm (32) reciprocates in the front-rear direction by a certain angle (β) by stably supporting the second air suction hose (39). The first and second air suction hoses (38) and (39) are provided with a level difference that does not interfere with each other.

(57) is an open / close valve for the air vent hole (56), and is pendulum-type connected to the front of the relay stand (C) via a hinge (58) attached to the top surface of the relay stand (C). It is suspended. Reference numeral (59) denotes a sealing material such as rubber that is attached to and integrated with the rear surface of the flat opening / closing valve (57) that is in surface contact with the relay stand (C). The air release hole (56) is closed. Keep airtight.

  Reference numeral (60) denotes a weight attached to the lower end portion of the on-off valve (57) suspended as the pendulum type, and the on-off valve (57) is moved by its own gravity as shown in FIGS. The air punching hole (56) is pressed and urged in a direction to be always closed.

  Moreover, the weight (60) has a certain length (L3) from the air suction hose relay stand (C) and the on-off valve (57) to the lateral side (left side as viewed from the front in the figure) as shown in FIGS. ) And the weight extension surface (60a) is in a front-rear positional relationship facing the tip of the rotating arm (32).

  From the front surface of the distal end of the rotating arm (32), a horizontal pressing screw rod (61) of the weight extension surface (60a) is integrally projected, and the rotating arm ( 32), with the output shaft (34) of the reversible motor for driving (33) as the rotation center (P), as shown in FIGS. 16 to 18, moves forward from the laver (M) in the laver storage tray (T). Each time the actuator moves backward, the weight extension surface (60a) is pressed by the pressing screw 杆 (61), and the on-off valve (57) opens the air vent hole (56) of the air suction hose relay stand (C). It is designed to be opened.

  In that case, the pressing screw rod (61) of the weight extension surface (60a) is advanced and retracted from the front, so that the degree of the pressing and the sealing state of the air vent hole (56) can be accurately positioned and adjusted. it can. (62) is a fixing nut of the pressing screw 杆 (61), and (63) is a sound deadening pad made of rubber or the like, which is attached to and integrated with the tip head (front end) of the pressing screw 杆 (61). Metal touch with weight extension surface (60a) is prevented.

  That is, the nori pad (36) attached to the tip of the rotating arm (32) is moved backward from the nori storage tray (T) by the forward movement of the rotating arm (32). When M) is sucked one by one and returned to the front, the pressing screw ６１ (61) attached to the tip of the rotating arm (32) is attached to the weight extension surface of the on-off valve (57) ( 60a) is pushed forward to open the air vent hole (56) of the air suction hose relay stand (C), so that the sucking force of the nori pad (36) is released. is there.

  As described above, the laver (M) is pulled out forward from the laver storage tray (T) by the laver sucker pad (36) of the rotating arm (32), and in the process of being separated, the laver bending guide roller (22) ) And bends and deforms using this as a fulcrum, and is pulled out longer by a certain length substantially corresponding to the amount of bending.

  Therefore, when the sucking force of the sucking pad (36) is released, the seaweed (M) is restored to the original developed form, and is received by the front surface of the nori receiving roller (20a) located on the feeding direction side (left side). As a result, the seaweed storage tray (T) protrudes laterally outward from the laver feeding direction side (left side) by a certain length (L4) (for example, about 20 mm). The overgrown portion (m) of the seaweed (M) fed out from T) can be reliably picked by the sushi cook of Gunkan Maki (A) with the fingertip of one hand.

  For the overhang portion (m) that serves as a picking margin for the laver (M), the fixed angle (β) for reciprocating movement of the rotating arm (32), the mounting position of the laver bending guide roller (22), and the like are selected. Thus, the length can be adjusted to the appropriate constant length (L4).

  Further, (64) is a laver feeding detection sensor directed to the overhanging portion (m) of the laver (M), and preferably comprises a reflective photoelectric switch, corresponding to the side surface of the installation box (B) ( It is fixedly supported on the left side via a sensor bracket (65).

  When the seaweed feeding detection sensor (64) detects the overhanging portion (m) of the seaweed (M), the seaweed (M) still remains without being picked. While the reversible motor (33) for driving the rotating arm (32) is kept stopped, the detection sensor (64) is also turned on after the standby time (for example, about 1 to 2 seconds) set by the preliminary timer has elapsed. When the overhang portion (m) of the seaweed (M) is not detected, the reversing motor (33) for rotating the arm is rotated each time so that the laver (M) is fed out. It has become.

  (66) is an operation switch installed on the same side (left side) as the laver feed detection sensor (64) in the installation box (B). Unless the operation switch (66) is turned on, the laver feeding device is not operated.

  In addition, the printed wiring board (sequencer) of such an electric control circuit is also stored and installed in the installation box (B). The entire installation box (B) is covered with a transparent synthetic resin opening / closing cover from above during use, but the hinge (679) for pivotally mounting the opening / closing cover is shown in the figure.

  In using the present invention configured as described above, the installation box (B) is installed on a cooking table such as a rotating sushi restaurant, and is supported in a state of being inclined downward at a certain angle (α). A pair of left and right laver-receiving rollers (20a) from the front of the laver storage tray (T) as an aligned bundle with a certain amount of strip-like laver (M) (about 300 sheets illustrated above) standing upright. ) (20b) is stored in a state where it is received, and the laver pressing roller (7) fitted in the laver storage tray (T) is prepared in a biased state in which the laver (M) is pressed from behind.

  Then, the sushi cook of the warship roll (A) may stand on the laver (M) feed direction side (left side as viewed from the front in the figure) and turn on the power switch and the operation switch (66). FIG. 11 shows an initial state in which the rotating arm (32) stops moving backwards forward during the operation.

  That is, since there is no laver (M) drawn out from the laver storage tray (T) at the beginning of operation, it is waiting for the time set by the pre-timer (about 1 to 2 seconds as exemplified above) Based on the output signal of the seaweed feeding detection sensor (64) that detects the absence of the seaweed (M), the rotating arm (32) automatically reciprocates in the front-rear direction by one stroke, One piece of laver (M) is fed out from T), and is kept in a state of projecting laterally outward by a certain length (m) from the laver feeding direction side (left side) as shown in FIG.

  Therefore, if the sushi chef picks it up with the fingertip of one hand, based on the output signal of the laver feeding detection sensor (64) that detects that the laver (M) is lost, the rotating arm (32) From the stopped state of FIG. 11, as shown in FIG. 12, it moves backward in contact with the laver (M) in the laver storage tray (T), and the laver sprinkling pad (44) in the middle part of the laver (M) ).

  At that time, the laver (M) is pressed at a position eccentric to the side opposite to the feeding direction side (right side when viewed from the front in the figure), so that it is distorted and deformed as shown in FIG. ), The horizontal end (left end) of the feeding direction side moves to the opposite side (inside) as shown by the arrow (E) in the figure, The left seaweed catching roller (20a) at the corner of the front end corner that was catching is detached.

  Then, the position where the nori (M) deformed and deformed in this way is decentered toward the feeding direction side (left side) is continuously brought into surface contact by the nori sucking pad (36) corresponding to the tip of the rotating arm (32). It is pushed into the state and sucked into the sucking pad (36).

  In this case, as shown in FIGS. 14 and 15, the rotating arm (32) is located at the rearward movement end point away from the air suction hose relay stand (C), and the air suction branch path at the relay stand (C). Since the air vent hole (56) of (54) is sealed by the on-off valve (57) that receives the gravity of the weight (60), the air suction force of the vacuum pump (41) absorbs the seaweed (M). As a force, it works effectively on the seaweed blotting pad (36).

  The laver (M) sucked by the seaweed sucker pad (36) is moved backward by the revolving arm (32) toward the front, and the middle part of the seaweed bending guide roller (22) as shown in FIG. Is bent with the bending guide roller (22), which is free to rotate, as a fulcrum, and then pulled forward and separated, the arrow (F) in FIG. ), It is transferred by itself to the feeding direction side (left side).

  As a result, at the end of the backward movement of the rotating arm (32), the pressing screw rod (61) attached to the tip thereof presses the overhang extension surface (60a) of the weight (60), thereby When the open / close valve (57) opens the air vent hole (56) of the air suction hose relay stand (C), the seaweed (M) released from the seaweed sucking pad (36) of the rotating arm (32) is 16, restored to the unfolded state as indicated by the chain line in FIG. 16, and a nori catching roller (20 a) facing the corner of the front end corner on the side of the laver feeding direction (left side) by a certain length (m) pulled out and transferred first. As a state of contact with the front surface of the paper, it protrudes laterally outward from the feeding direction side.

  Therefore, the sushi cooker can reliably pick up with the fingertip of one hand using the overhang portion (m) of the seaweed (M) fed out in this way as the picking allowance.

  By repeating such a process, the laver (M) can be smoothly and smoothly fed out one by one from the storage tray (T), and the laver storage tray (T ) Is lifted up and down to give a positive rolling shock to the laver pressing roller (7), and the laver (M) is pushed forward. In addition, the laver feeding device of the illustrated embodiment has a processing capacity for delivering about 40 laver (M) per minute.

  FIG. 19 shows a partially modified embodiment of the present invention corresponding to FIG. 15, in which a plurality of air suction passages (37) are provided on the laver sucking pad (36) of the rotating arm (32). Also, the air suction hose relay stand (C) is provided with a plurality of air suction branch passages (54) and air vent holes (56), respectively, and one end portion of each air suction branch passage (54), The air suction passages (37) are connected to each other by the first air suction hose (38), and the other end of the air suction branch passage (54) and the vacuum pump (41) are connected to the second and third air suction hoses. (39) The communication connection is established by (40).

  By adopting such a configuration in which a plurality of air suction paths are arranged in parallel, even if the laver (M) is in a punctured state, it can be sucked out without error by the sucking pad (36). There is an effect that a reliable feeding operation can be performed.
