Description

  TECHNICAL FIELD The present invention relates to a seaweed tearing apparatus that mainly cuts long seaweeds such as stem seaweed along the longitudinal direction thereof into thin lines.

  In general, seaweed as seaweed is processed into so-called dried wakame and salted wakame using leaf portions, and the middle muscle and stem portions removed when processing remain as so-called stem wakame. This stem seaweed is also used for food, but in that case, it is cut along the longitudinal direction and processed into a thin line (thread). Conventionally, this processing is performed by using a needle base in which needles are implanted, holding one end of a stalk wakame by hand, and rubbing with a needle while manually rubbing the needle base into a thin line shape. However, since the processing efficiency is low in manual work, various processing apparatuses that can automatically perform processing have been proposed.

Conventionally, as this type of processing apparatus, for example, one end of a stem squirrel is clamped and placed on a rotating belt along a moving direction, and a holder in which needles are arranged at a predetermined interval is lowered at a starting end position. The rotating belt is moved in the moving direction, lifted at the end position, moved to the starting position, and repeatedly lowered again. (For example, published in Japanese Patent Laid-Open No. 60-41471).
In addition, conventionally, for example, supplying stem wakame from a hopper, feeding it while holding the stem wakame with a low speed induction roll, and receiving the stem wakame fed from this induction roll with a receiving roll coated with a hard synthetic resin A roll-shaped needle holder in which needles are arranged at predetermined intervals with respect to the receiving roll is rolled at high speed, and the needle protrudes in front of the receiving roll and then retracts. Some stalks that reach the receiving rolls are crushed and torn (for example, see JP-A-60-176666).

JP-A-60-41471 JP 60-176666 A

By the way, in the former former processing apparatus, the holder in which the needles are arranged is lowered at the start position, moved in the moving direction of the rotating belt, raised at the end position, moved to the start position, and lowered again. Since the process is repeated, there is a problem that the apparatus becomes large and the moving distance of the needle holder becomes long, so that the processing speed is slow and the processing efficiency is deteriorated. Further, since the needles are arranged at predetermined intervals, there is a problem that the seaweed is not easily thinned even if it is repeatedly sown.
On the other hand, in the latter latter processing apparatus, since the roll-shaped needle holder in which the needles are arranged with respect to the receiving roll is rolled at a high speed, the processing speed is fast, but the holding of the stem wakame is fed at a low speed. Due to the induction roll, the posture of the stem wakame becomes irregular, so it is difficult to tear the stem wakame in its longitudinal direction, and therefore, many of the pieces are torn off, and the same as the former device Since the needles are arranged at predetermined intervals, the seaweed is difficult to thin even if it is repeatedly crushed.

  The present invention has been made in view of the above points. The seaweed can be surely torn along the longitudinal direction, and can be surely thinned to improve the quality of the product and increase the processing speed. It is an object of the present invention to provide a seaweed tearing device that improves processing efficiency.

In order to achieve such an object, the seaweed tearing device according to the present invention is a seaweed tearing device that tears an elongated seaweed along its longitudinal direction into a thin line shape, and has one end portion of the seaweed as described above. A clamp mechanism for clamping, and a drum having an outer peripheral surface on which the other end side of the seaweed clamped by the clamp mechanism is placed and rotated in a direction to separate the other end side of the seaweed from the clamp mechanism; A rotation drive unit that rotates the drum, and a plurality of the outer peripheral surfaces of the drum that are wound from the one side in the axial direction of the drum toward the other side by the rotation of the drum. The needles are arranged in a row so that the interval between the plurality of needles gradually or gradually decreases from one side to the other side in the axial direction of the drum, and the clamp mechanism is moved in the axial direction of the drum. It has a configuration which is to function.
In this case, it is preferable to determine the positional relationship between the drum and the clamp mechanism so that the needle penetrates into a portion as close as possible to one end of the seagrass clamped by the clamp mechanism.

  Thus, when processing seaweed, first, in a state where the clamp mechanism is positioned on one side of the drum, bundle a plurality of seaweeds and clamp one end of the seaweed onto the clamp mechanism, and the other end of the seaweed on the drum The drum is rotated by the rotation drive unit. By rotating the drum, first, the needle row on the side where the needle interval is coarse enters and penetrates the seaweed, and the needle repeatedly crawls and tears the seaweed. For this reason, seaweed is first thinned relatively coarsely. When the clamp mechanism is moved sequentially from one side of the drum to the other side, the seagrass also moves in accordance with this, and the interval between the needles is gradually narrowed. As it comes to be sown, the seaweed with coarse thickness is gradually subdivided. In this case, if necessary, the clamp mechanism may be reciprocated by a required distance. Therefore, as compared with the conventional method of repeatedly piercing with a row of needles arranged at a predetermined interval, the seaweed can be surely torn along the longitudinal direction and can be surely thinned, thereby improving the quality of the product. be able to. In the case of rowing with a needle line having a narrow interval from the beginning, the seaweed is easily cut off and the yield is deteriorated, but in the present invention, the seaweed is difficult to cut off because it can be gradually subdivided. Can be greatly improved. Furthermore, since the drum provided with the needles is rotated and rolled, the processing speed is high, and therefore the processing efficiency can be greatly improved. When the seagrass fragmentation is in the desired state, the drum stops rotating, the clamp mechanism is released, and the seagrass is removed from the clamp mechanism. One end of this clamped seaweed is still thick, but if necessary, cut this part or hold it in a bundled state and use a needle stand with a conventional needle implanted. You may process suitably, such as tearing with a needle | hook and rubbing with a fine line shape, rubbing to a needle stand by manual labor.

And if necessary, the needle rows in which the plurality of needles are arranged are provided in a plurality of rows along the circumferential direction of the drum. Since the frequency at which seaweed is sown by the needle row per drum rotation increases, the processing speed can be increased accordingly.
Further, if necessary, in all or a part of the needle rows, the needles are inclined toward the downstream side in the rotation direction of the drum. As a result, when the needle enters the seagrass, the needle comes into an acute angle, so that the needle can be surely stuck and can be subdivided reliably.
Furthermore, if necessary, there is provided a rod-like needle stand that has a planting surface on which each needle of the needle row is implanted and whose longitudinal direction is attached to the outer peripheral surface of the drum along the axial direction of the drum, A plurality of needle stands are provided at predetermined intervals on the outer peripheral surface of the drum. As a result, seaweed once sown by the needle is placed on the outer peripheral surface of the drum between the needle base with the needle row, so that the seagrass is intermittently lifted up to the needle stand by the needle row. Compared to the case where the needle is directly planted on the outer peripheral surface of the drum, and compared to the case where the needle is continuously pierced with the needle, the needle is easily pierced in the seaweed. The needle can be surely stabbed, and it can be reliably subdivided.

  Furthermore, if necessary, the needle base is configured to include a first planting surface that faces the downstream side in the rotation direction of the drum and a second planting surface that heads the upstream side in the rotation direction of the drum. A plurality of needle rows are provided on the planting surface, and a part or all of the needles of the needle row are provided on the second planting surface. As a result, since there are multiple needle rows on the first planting surface, the probability of needle sticking into the seagrass is increased, and in this respect, needle sticking can be ensured and the fragmentation is ensured. can do. In addition, since the needle is also provided on the second planting surface, this needle has a little gap from the needle on the first planting surface, and the angle is different, so that another portion of the seagrass can be seeded. It is possible to reliably subdivide in this respect.

  If necessary, the clamp mechanism includes a base that can move in the axial direction of the drum via a rail with respect to the machine base, and a gripping part that is supported by the base and grips one end of the seaweed. And a moving drive unit for moving the clamp mechanism. Thereby, since the movement of the clamp mechanism can be automated, the machining efficiency can be improved accordingly.

  In this case, if necessary, the movement drive unit is connected to a chain having one end attached to one end of the base in the moving direction and the other end attached to the other end of the base in the moving direction, and movement of the base of the machine base. A guide roller provided on one end side and the other end side of the direction and guided by a chain being wound around, a sprocket provided on a machine base below the base and meshed with the chain, and rotating the sprocket And an electric motor that moves the base via the chain. Since it is a chain drive, the device can be simplified.

  Further, if necessary, a control unit for the movement drive unit is provided, and the control unit moves the clamp mechanism from a starting end position on one side in the axial direction of the drum to a terminal position on the other side through a predetermined intermediate position. The clamp mechanism is configured to have a function of reciprocating a predetermined number of times between the end position and the midway position when the end position is reached, and then returning the clamp mechanism to the start position. Thereby, since the movement of the clamp mechanism can be automated, the machining efficiency can be improved accordingly. In addition, when the clamp mechanism reaches the end position, it is reciprocated a predetermined number of times between the end position and the middle position, so that the seaweed can be repeatedly sown by the needle row with the narrowest needle interval, and thus more reliably. It can be made thinner and the product quality can be improved.

  Further, if necessary, the gripping part is supported so as to be rotatable about an axis perpendicular to the axis of the drum with respect to the base, and the gripping part is rotated in cooperation with the gripping part. The manual handle is provided. As a result, when the gripping part is rotated with the manual handle while moving the clamp mechanism, the seaweed also tries to rotate, so that another part of the seaweed can be spread. Can be subdivided reliably.

  Further, if necessary, the gripping portion includes a base body, one gripping body projecting from one end of the base body, and the other gripping body projecting from the other end of the base body. The gripping body is configured to include a one gripping body main body and a substantially U-shaped one clamp member that is provided at a distal end portion of the one gripping body main body and holds seaweed, and the other gripping body is configured as the other gripping body. A main body, a substantially U-shaped other clamp member which is provided at a tip of the other gripping body main body and holds seaweed while holding the seaweed in cooperation with the one clamp member; And a pressing mechanism that presses the clamp member. Since the sea grass is held by the substantially U-shaped one clamp member and the other clamp member, the sea grass is securely clamped.

  Furthermore, if necessary, the pressing mechanism includes a male screw rod provided with the other clamp member at the tip and supported by the other gripping body main body so as to be able to advance and retreat, and a male screw formed thereon, and the male screw rod. An operating handle to be operated and a nut having a female screw provided in the other gripping body main body and screwed into the male screw of the male screw rod are configured. Since the male screw rod is screwed onto the nut and tightened by the operation handle, the seagrass is securely grasped.

  In this case, if necessary, the nut is split and formed, and the nut is provided at one end and is rotatably provided on the other gripping body main body. The nut is screwed onto the male screw of the male screw rod by rotation. An operating rod which can be moved to a screwing position to be engaged and a release position where the screwing is released, biasing means for biasing the operating rod to the screwing position of the nut, and the mounting rod provided on the operating rod. And a knob portion for rotating the operating rod against the urging force of the urging means to position the nut at the release position. As a result, when gripping seaweed, the knob is operated and the operating rod is rotated against the urging force of the urging means to position the nut at the release position, and the male screw 杆 is moved to clamp the other The member is separated from the one clamp member. In this case, since the male screw rod is released from the nut, the movement is free, and it is not necessary to rotate the nut one by one, so that the operability is improved accordingly. In this state, place one end of the seaweed between the one clamp member and the other clamp member, and operate the knob to rotate the operating rod against the urging force of the urging means to position the nut in the release position. Then, the male screw rod is moved, and the other clamp member is pressed against the seaweed on the one clamp member. Also in this case, since the male screw rod is released from the nut, the movement is free, and it is not necessary to rotate the nut one by one, so that the operability is improved accordingly. Then, when the hand is released from the knob portion, the operating rod is rotated by the urging force of the urging means, the nut is positioned at the screwing position, and the male screw of the male screw rod is screwed into the nut. In this state, the male screw rod is rotated by the operation handle, screwed into the nut and tightened, and one end of the seaweed is gripped and fixed. In this case, since the process of screwing the male screw is extremely short, the operability is improved.

  Moreover, it is set as the structure which supported the said other holding body rotatably with respect to the said base | substrate as needed. When the one end of the seaweed is gripped between the one clamp member and the other clamp member, the other gripping body can be rotated and shifted with respect to the base body, so that the seaweed can be easily clamped.

  If necessary, the gripping portion is provided on the base body, a belt that holds one end side of the base body and the other end side is movably held with respect to the one end side, and holds the seaweed, and is rotatably provided on the base body. And the other end of the belt is fastened to wind the belt so that the wrapped seaweed can be held in the winding direction, and the belt can be rewound to release the seaweed holding direction. A reel that is rotated, a holding position that is provided between the reel and the rotation shaft of the reel and that allows rotation in the winding direction of the reel and restricts rotation in the rewinding direction; It comprises a ratchet mechanism that can be switched between two release positions that restrict rotation and allow rotation in the rewind direction, and a lever that rotates the reel. Since the seaweed is held by the loop-shaped belt, gripping is ensured, and the reel can be held and released just by rotating it via the ratchet mechanism, so operability is extremely improved and workability is improved. Be made.

  In this case, it is effective to provide a reel lock mechanism for releasably locking the reel. Since the reel does not move carelessly, the operation of the apparatus can be surely performed.

  According to the present invention, when processing seaweed, the needle enters the seaweed by the rotation of the drum, and the needle repeatedly crawls and tears the seaweed. In this case, when the clamp mechanism is sequentially moved from one side of the drum to the other side, the seaweed is also moved in accordance with this, but since the interval between the needles is gradually narrowed, the seaweed is gradually separated. Since it is sown by a narrow needle row, the seaweed with coarse thickness is gradually subdivided. Therefore, as compared with the conventional method of repeatedly piercing with a row of needles arranged at a predetermined interval, the seaweed can be surely torn along the longitudinal direction and can be surely thinned, thereby improving the quality of the product. be able to. In the case of rowing with a needle line having a narrow interval from the beginning, the seaweed is easily cut off and the yield is deteriorated, but in the present invention, the seaweed is difficult to cut off because it can be gradually subdivided. Can be greatly improved. Furthermore, since the drum provided with the needles is rotated and rolled, the processing speed is high, and therefore the processing efficiency can be greatly improved.

In this case, since the male screw rod 71 is released from the nut 73, the movement becomes free and it is not necessary to rotate the nut 73 one by one, so that the operability is improved accordingly. In this state, one end portion of the seaweed W is placed between the one clamp member 64 and the other clamp member 66 and the knob portion 76 is operated to rotate the operation rod 74 against the urging force of the urging means 75. The nut 73 is positioned at the release position Y, the male screw rod 71 is moved, and the other clamp member 66 is pressed against the seaweed W on the one clamp member 64. Also in this case, since the male screw rod 71 is released from the nut 73, the movement becomes free, and it is not necessary to rotate the nut 73 one by one, so that the operability is improved accordingly. Further, when the one end of the seaweed W is gripped between the one clamp member 64 and the other clamp member 66, the other gripping body 62 can be rotated and shifted with respect to the base body 60. Therefore, the seaweed W can be easily clamped.

  Then, when the hand is released from the knob portion 76, the operating rod 74 is rotated by the urging force of the urging means 75 so that the nut 73 is positioned at the screwing position X, and the male screw of the male screw rod 71 is attached to the nut 73. Screw together. In this state, the male handle 71 is rotated by the operation handle 72 and screwed into the nut 73 and tightened, and one end of the seaweed W is gripped and fixed. In this case, since the process of screwing the male screw is extremely short, the operability is improved. Further, since the male screw rod 71 is screwed onto the nut 73 and tightened by the operation handle 72, the seagrass W is securely gripped. Since the seaweed W is held by the substantially U-shaped one clamp member 64 and the other clamp member 66 by tightening the male screw rod 71, the seaweed W is reliably clamped.

  When the seagrass W has been clamped, the start button is pushed. As a result, the drum 10 is rotated by the rotation drive unit 20 as shown in FIG. 9, and first, as shown in FIG. 8A, the needle row NL on the side where the needle N is coarse is stuck in the seaweed W. The needle N repeatedly hits the seaweed W and splits. For this reason, the seaweed W is thinned relatively coarsely first. Then, as shown in FIG. 8B, the clamp mechanism C is sequentially moved from one side of the drum 10 to the other side by the movement drive unit 42, and the seaweed W is also moved sequentially according to this, and the needle N Since the interval is gradually narrowed, the seaweed W is gradually beaten by the needle rows NL having a narrow interval, so that the seaweed W having a coarse thickness is gradually subdivided. When the clamp mechanism C reaches the end position A2 on the other axial side of the drum 10 and the end sensor 81 detects this, the clamp mechanism C is reciprocated a predetermined number of times between the end position A2 and the midway position A3. For this reason, the seaweed W can be repeatedly sprinkled by the needle row NL having the narrowest interval between the needles N, and therefore, the submerged can be more reliably subdivided.

  Further, in the process of moving the clamp mechanism C, as shown in FIG. 5, the grip portion 50 can be rotated by the manual handle 53. In this case, since the seaweed W is also going to rotate, another part of the seaweed W can be sown, and also in this respect, it can be surely subdivided. Further, since a plurality of needle bases 30 are provided at predetermined intervals on the outer peripheral surface 11 of the drum 10, the needle N is once attached to the outer peripheral surface 11 of the drum 10 between the needle base 30 with the needle row NL and the needle base 30. When the seaweed W that has been sown is placed, and the seaweed W is intermittently lifted to the needle base 30 and sown by the needle row NL, the needle N is directly implanted on the outer peripheral surface 11 of the drum 10. Compared with the case where the needle N is pierced with the needle N continuously, the needle N can be easily pierced into the seaweed W. Also in this respect, the puncture of the needle N can be ensured. Can be Furthermore, as shown in FIG. 9, the needle row NL implanted on the first implantation surface 31 of the needle base 30 has its needles N inclined toward the downstream side in the rotation direction R of the drum 10. Therefore, when the needle N penetrates the seaweed W and enters, the needle N comes to be stuck at an acute angle, so that the needle N can be reliably stuck and can be reliably subdivided. Furthermore, since a plurality of needle rows NL are provided on the first planting surface 31, the probability that the needle N will pierce the seagrass W increases accordingly. In this respect, the needle N can be reliably pierced. Can be subdivided. Also, since the needle N is provided on the second planting surface 32, the needle N is slightly spaced from the needle N of the first planting surface 31, and the angle is different. Another site can be crushed, and in this respect it can be reliably subdivided.

  As described above, according to the present tearing device S, the seaweed W is reliably torn along the longitudinal direction as compared with the conventional method in which the needle row NL is repeatedly arranged at predetermined intervals. Therefore, it can be surely made thinner and the product quality can be improved. In addition, when the needle rows NL are narrowly spaced from the beginning, the seaweed W is easily cut off and the yield is deteriorated. However, in the tearing device S, the seaweed W can be subdivided gradually. Therefore, the yield is greatly improved. Furthermore, since the drum 10 provided with the needle N is rotated and rolled, the processing speed is fast, and therefore the processing efficiency can be greatly improved. Furthermore, since a plurality of needle rows NL in which a plurality of needles N are arranged are provided along the circumferential direction of the drum 10, the frequency at which the seaweed W is beaten by the needle rows NL per rotation of the drum 10 increases. Therefore, the processing speed can be increased accordingly.

Thereafter, when the clamp mechanism C reaches the start position A1 and the start sensor 80 detects this, the clamp mechanism C is stopped and the drum 10 is also stopped, and the processing of the seaweed W is finished. Then, the clamp of the clamp mechanism C is released and the seaweed W is removed from the clamp mechanism C. Also in this case, the knob 76 is operated to rotate the operating rod 74 against the biasing force of the biasing means 75 so that the nut 73 is positioned at the release position Y, and the male screw rod 71 is moved to clamp the other side. The member 66 is separated from the one clamp member 64. Therefore, since the male screw rod 71 is released from the nut 73, the movement becomes free and it is not necessary to rotate the nut 73 one by one, so that the operability is improved accordingly.
In the removed seaweed W, one end of the clamped seaweed W is not thick because the needle N does not pass through it, but if necessary, this part is cut or bundled as it is. It may be appropriately processed such as gripping and tearing with a needle while rubbing it on the needle base by hand using a needle base in which a conventional needle is implanted. In this way, the seaweed W is subdivided by repeating the above operation.

  10 and 11 show another gripping portion 90 of the clamp mechanism C in the seaweed tearing device S according to the embodiment of the present invention. The grip 90 includes a base 92 having a tongue piece 91 provided on the rotating shaft 51 and projecting toward the drum 10 at the lower end. At the tip of the tongue piece portion 91 of the base 92, one end side is drawn through and held by a pair of holes 93, and the other end side is held movably with respect to the one end side to hold one end portion of the seaweed W. A belt 94 made of flexible plastic is provided to be held together with the tip of the tongue piece 91. A guide member 95 through which the other end side of the belt 94 is drawn is provided at one end of the belt 94. Since the guide member 95 is larger than the inner diameter of the hole 93, one end of the belt 94 is prevented from being detached from the hole 93. ing. In addition, the other end of the belt 94 is fastened to the base 92, and the winding direction Ka in which the belt 94 is wound and held can be held, and the belt 94 is rewound to release the holding of the seaweed W. A reel 96 that is rotated in the rewind direction Kb is provided. The reel 96 is rotatably supported on a rotating shaft 98 that is supported by a pair of bearing plates 97 that are erected on the tongue piece 91 of the base 92. Between the reel 96 and the rotation axis 98 of the reel 96, a holding position that allows the reel 96 to rotate in the winding direction Ka and restricts the rotation in the rewinding direction Kb, and the reel 96 winding direction. A known ratchet mechanism 99 that can be switched by a switching lever (not shown) is provided at two release positions that restrict the rotation of Ka and allow the rotation in the rewinding direction Kb. A lever 100 for rotating the reel 96 is provided outside the one bearing plate 97 in cooperation with the reel 96.

  Further, a reel lock mechanism 101 is provided for locking the reel 96 so that the rotation of the reel 96 can be released. The reel lock mechanism 101 is provided with a pair of mounting plates 102 projecting toward the drum 10 at the upper end of a base 92 and spaced apart at a predetermined interval, and an engaging recess 103a that engages the lever 100 at the tip between the mounting plates 102. The engagement piece 103 having a slidable arrangement is provided. The pair of mounting plates 102 are provided with coaxial insertion holes. Bolts 105 that are secured by nuts 104 are inserted into the insertion holes, and the engagement pieces 103 are provided with long holes 106 that are inserted through the bolts 105. It has been. By engaging the engaging recess 103a with the lever 100 when the engaging piece 103 advances, the bolt 105 and the nut 104 are tightened to lock the rotation of the reel 96 via the lever 100, and the bolt 105 and the nut 104 are loosened. Then, the engagement piece 103 is moved backward, the engagement recess 103 a is separated from the lever 100 to release the lock, and the rotation of the reel 96 by the operation of the lever 100 is allowed.

  Therefore, when the seaweed W is gripped by the gripping portion 90, the bolts 105 and nuts 104 of the reel lock mechanism 101 are loosened, the engagement piece 103 is retracted, the lock is released, and the ratchet mechanism 99 is positioned at the release position. By operating the lever 100, the belt 94 is rewound to widen the loop of the belt 94. In this state, one end of the seaweed W is inserted into the loop of the belt 94 and held. Then, this time, the ratchet mechanism 99 is positioned at the holding position, the belt 94 is wound up by the operation of the lever 100, and the held seaweed W is held. Thereafter, the lever 100 is positioned at the neutral position, the engagement piece 103 of the reel lock mechanism 101 is advanced, the engagement recess 103a is engaged with the lever 100, and the bolt 105 and the nut 104 are tightened to lock. Thereby, the seaweed W is clamped. In this case, since the seaweed W is held by the loop-shaped belt 94, gripping is ensured, and the seaweed W can be held only by rotating the reel 96 via the ratchet mechanism 99, so that the operability is extremely good. Thus, workability is improved.

  Then, similarly to the above, when the seagrass W has been clamped, the start button is pushed, and the seagrass W is crushed and split. During this operation, the reel 96 is locked by the reel lock mechanism 101, and the reel 96 does not move carelessly, so that the operation of the apparatus is reliably performed. When the series of operations is completed, the bolt 105 and nut 104 of the reel lock mechanism 101 are loosened to release the engagement piece 103 to release the lock, and the ratchet mechanism 99 is positioned at the release position and the lever is released. The belt 94 is rewound by the operation of 100, and the loop of the belt 94 is expanded. In this state, one end of the seaweed W is extracted from the loop of the belt 94. In this way, these operations are repeated to subdivide the seaweed W.

  In addition, in the seaweed tearing apparatus S according to the above-described embodiment, the configuration of the clamp mechanism C and its gripping portions 50, 90, etc. is not limited to the above-described configuration, and may be appropriately changed. Moreover, in the seaweed tearing processing apparatus S according to the above-described embodiment, the example of the seaweed Wakame has been described as the seaweed W. However, the present invention is not necessarily limited thereto, and may be applied to various seaweeds W such as kelp. Of course it is good.
