Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically performing processing from strip-shaped cutting of regular laver to bagging. 2. Description of the Related Art As shown in FIGS. 7 and 8, the applicant has previously proposed a device for cutting fixed laver into small strips and packing the same into a bag (Japanese Patent No. 3081810). The bag filling device includes a laver supply device (100) that draws out and supplies one by one the laminated stock of fixed size seaweed, and a horizontal cutting device that cuts the supplied fixed size seaweed to a predetermined width orthogonal to the supply direction.
(2) and a plurality of buckets (31) (31) arranged below the horizontal cutting device (2) at equal intervals in the circumferential direction, and intermittently rotating in accordance with a predetermined number of cuts of the horizontal cutting device (2). A bucket roller (3) for receiving the strip of seaweed falling from the horizontal cutting device; a vertical cutting device (4) arranged below the bucket roller (3) for cutting the strip of seaweed into strips in the vertical direction; The two films F1 and F2 are rolled up from both sides of the strip laver falling path, which is disposed below the device (4), the strip laver is sandwiched between the films, and the films F1 and F2 are perpendicular to the film moving direction and the film moving direction. And a heat-sealing sealing device (6) for performing heat-sealing in the direction in which the small bags are sealed. [0003] The horizontal cutting device (2) is used to cut a predetermined number of sheets of seaweed one by one, and a predetermined number of cut strips of seaweed are stored in a bucket (31) of a bucket roller (3). When rotating the bucket roller (3) to drop it into the lower vertical cutting device (4), one bucket
The plurality of strips of seaweed in (31) fall not in a bundle but in pieces. For this reason, a deviation occurs in the timing at which a plurality of band-shaped laver passes through the vertical cutting device (4), and the strip-shaped laver falls apart from the vertical cutting device (4). Further, the strip-shaped laver may pass through the vertical cutting device (3) in an obliquely inclined state and be cut into strips longer than the setting. [0004] When the strip-shaped laver falls between the packaging films F1 and F2 in a fragmented state, and when the strip-shaped laver contains a longer length than the set length, the heat-sealing seal for separating the bags of the films F1 and F2 from each other is used. There was a problem that strip-shaped laver was interposed in the planned portion, resulting in incomplete heat-sealing seals and defective products. The present invention is to clarify a strip-shaped laver bagging apparatus which solves the above-mentioned problem. [0005] A strip-shaped laver packing apparatus of the present invention supplies a laver supply device (100) for supplying a plurality of standard laver N in a stacked state, and supplies the supplied laver. Transverse cutting device (2) for cutting to a predetermined width orthogonal to the direction, and transverse cutting device

A heat-sealing sealing device (6) for winding two films F1 and F2, sandwiching a strip of laver between the films, heat-sealing the films F1 and F2 in a direction orthogonal to the direction of film transfer, and separating and sealing the small bags. It is constituted by and. [Action and effect] Since a plurality of sheets of standard laver N are cut horizontally, the cut laver N1 is cut vertically with a plurality of laminations, and the cut laver N2 is cut.
, A plurality of pieces in a lump fall between the furums F1 and F2 almost simultaneously. As in the past, nori was not supplied and cut one by one, so strip-shaped laver longer than the setting was not discharged. Also, the strip-shaped laver was disintegrated between the packaging films F1 and F2. Can also be prevented from falling. For this reason, there is no risk that strip-shaped seaweed longer than the setting is included or that strip-shaped seaweed falls apart in time between the films F1 and F2 and falls off. Part of strip nori N

(10) is provided, and a film F is provided in front of the reversing roller (10).
1.Pouch cutting device that cuts each bag in the flow direction of F2
(7) is deployed. The pouch cutting device (7) includes a longitudinal cutting portion (71) for cutting two inner welding portions in the longitudinal direction of the welding portion among the four band-like welding portions S1 in the film traveling direction.
And a transverse cutting portion (72) disposed downstream of the longitudinal cutting portion and cutting the band-like welded portion S2 in a direction perpendicular to the film traveling direction in the longitudinal direction of the welded portion. The vertical cutting section (71) is composed of a disk-shaped rotary blade (71a) and a receiving roller (71b), and the horizontal cutting section (72)
Is a bar-shaped fixed blade (7) in the same manner as in the transverse cutting device (2).
2a) and a rotating bar-shaped cutting blade (72b). First and second conveyors of laver supply device (100)
(103), (104), the horizontal cutting device (2), the vertical cutting device (4), the heat sealing and sealing device (6) and the pouch cutting device (7) are driven by a common drive source and operate at a constant timing. . However, the fixed laver N pulled out one by one from the stocker (101) onto the first conveyor (103) is moved by the conveyer (105) to the parallel rod (10) at the ascending position of the delivery device (105).
5a) Handed over. This operation is repeated four times, and when the four fixed laver N are overlapped on the parallel rod (105a), the parallel rod descends and transfers the fixed laver N onto the second conveyor (104). The overlapping fixed laver N is conveyed to the horizontal cutting device (2) by the second conveyor (104). The parallel rod (105a) of the delivery device (105) rises again and waits until four fixed laver overlap on the parallel rod. The four-layered fixed laver N transported to the downstream side by the second conveyor (104) is fed to the horizontal cutting roller (21) waiting the groove (24) toward the second conveyor (104). ) Enters the groove (24) and hits the groove bottom. Overlapping laver is prevented from further progressing and slips against the second conveyor (104). The horizontal cutting roller (21) is rotated by one pitch to cut a quarter length of the standard laver N into a strip shape. The horizontal cutting roller (21) has a groove (24) on the opposite side to the second conveyor (1).
Stopping toward 04), the seaweed of 3/4 length of the standard seaweed enters the groove. In this way, one of the horizontal cutting rollers (21)
The strip laver N1 is discharged every pitch rotation. The seaweed shortened in the transport direction on the second conveyor (104) is pushed by the next fixed seaweed and enters the groove of the horizontal cutting roller (21). Since the horizontally long strip-shaped laver N1 cut by the horizontal cutting roller (21) is cut in a state in which four sheets of laver overlap, the lower vertical cutting device (4) is overlapped while maintaining the horizontal orientation. ) Falls between the vertical cutting rollers (41) and (42).
For this reason, the strip-shaped laver N1 can be cut into strips having a uniform length. Further, since the four strips of laver N1 are cut into strips in an overlapping state, the cut strips of laver N2 pass through the lower guide member (5) as a substantially lump of four strips.
At this time, the strip-shaped laver group is divided into three parts. The strip-shaped laver N2 passed through the guide member (5) is heat-sealed and sealed.
The film (6) falls between the two films F1 and F2 drawn between the rollers (61) and (62). At this time, the strip-shaped laver N2 is a guide member.
(5) The film F1, F2 that moves downward across the lower wall plate (53) and the wall plate (53) falls in a space surrounded on all sides by the films F1 and F2, so that it does not scatter outside. Is stored between the films F1 and F2 by a specified amount. The films F1 and F2 which are drawn between the rollers (61) and (62) while accommodating the strip-shaped laver press the outer peripheral portion of the concave portion (63) while passing the laver accommodating portion through the concave portion (63). It is heated and pressed by the rollers (61) and (62) to be sealed by heat welding. The sealed two-layer film is cut into pouches by the vertical cutting section (71) and the horizontal cutting section (72) of the bag cutting device (7). As described above, the strip-shaped laver N2 does not mix longer than the set length as in the prior art, and a plurality of four-layered laver N2 are almost simultaneously film F1, F2.
Since it is dropped in between and sealed by heat welding, it is possible to prevent the strip-shaped laver from being positioned at the portion to be sealed, thereby preventing the heat-sealing seal from being incomplete. In carrying out the present invention, it is one embodiment to cut the fixed nori N first into four rows or to divide the strip-like nori N1 into three parts in the horizontal direction and package them. Without being limited, the present invention can be variously modified within the scope described in the claims.
