  FIG. 1 is a perspective view showing the overall configuration of the apparatus. 1 is a conveyor installed horizontally by legs 2a and the like in a horizontal direction on a machine base 2, and is formed from two parallel rows of thin belts 1a and 1b. It is configured. The conveyor 1 has small holes 1 'extending in the longitudinal direction in the belts 1a and 1b, and sucks air from below the belts 1a and 1b, thereby adsorbing the laver packaging film (film material) F. It is comprised so that it can be conveyed by. The air suction type conveyor 1 is provided with an air duct (not shown) below the thin belts 1a and 1b. By sucking air through holes provided on the upper surface of the ducts, the belt 1a , 1b, which can suck air through the small holes 1 '. This conveyor 1 adsorbs the laver wrapping film F supplied onto the conveyor 1 from below the stocker 3 and intermittently conveys it in the direction of arrow A with the drive motor M1 (see FIG. 16) in this state. is there.

  As shown in FIG. 3, the laver wrapping film F is a rectangular bag-like film in which a rectangular laver N is packaged, and rectangular extension film portions F1 and F2 are formed at the rear end thereof in the left-right direction. As a whole, it is T-shaped. The seaweed packaging film F is stored in a stacked state in the stocker 3 from the upper opening 3 ′, and is supported by an engagement bar or the like (not shown) in the lower part inside the stocker 3.

  In the following description, the front side in the apparatus of FIG. 1 is referred to as “front”, the rear side is referred to as “rear”, the right side with respect to the sheet according to the conveying phrase of the conveyor is referred to as “upstream”, and the left side as “downstream” .

  A laver suction frame 4 with a plurality of film suction nozzles 4a attached to the upper part is provided at the lower part of the stocker 3, and as shown in FIG. 2, the laver suction part 4 rises in the direction of arrow B. The suction nozzle 4a sucks the lowermost sheet of the laver packaging film F, and the suction nozzle 4a descends to the lower side of the conveyor 1 as shown in FIG. The sheet is placed on the conveyor 1 that is stopped.

  When the laver wrapping film F is placed on the conveyor 1 directly below the stocker 3, the extension film portions F1 and F2 are positioned on the thin belts 1a and 1b and are adsorbed to the belts 1a and 1b. The front end portion is placed on the upper surface of the nori front end support plate 1c provided along the thin belt 1b on the front side of the conveyor 1 (see the position of the two-dot chain line on the film F in FIG. 3).

  Since the conveyor 1 is intermittently driven, the laver wrapping film 1 is driven in the direction of arrow A at a timing next to the time when the laver wrapping film 1 is placed on the conveyor 1, and the laver wrapping film F is conveyed to the film alignment position 5. (Refer to the solid line position of the film F in FIG. 3), it temporarily stops (state in FIG. 3). In addition, the intermittent drive of the conveyor 1 may be such that the drive is stopped at regular intervals by controlling the conveyor drive time, or the stop position of the laver wrapping film F (the film alignment position 5 and the air injection position 22 below). ) May be provided with a sensor (such as an optical sensor) that detects the arrival of the film F, and the driving of the conveyor 1 may be temporarily stopped based on the detection of the sensor.

Next, the configuration of the alignment portion at the film alignment position 5 will be described.
At the alignment position 5, an up-and-down inclined plate 6 is provided at a lower level position than the belts 1 a and 1 b between the thin belts 1 a and 1 b (see FIGS. 1 and 9). As shown in FIG. 12, the up-and-down inclined plate 6 is supported and fixed to a pair of support columns 7 and 7 in a state where it is inclined to the front side at a predetermined angle (about 45 degrees from the horizontal position).

It is comprised so that it can reciprocate.

  Since the up-and-down inclined plate 6 is connected to the nori suction frame 4, the up-and-down movement of the inclined plate 6 is the same as the up-and-down timing of the nori suction unit 4. Therefore, the up-and-down inclined plate 6 rises and sucks the laver packaging film F, descends and places the film 1 on the conveyor 1, and then the conveyor 1 moves to align the laver packaging film F with the film alignment. At the next timing, the laver suction frame 4 rises and sucks the next laver wrapping film F, but at the same timing, the up-and-down inclined plate 6 rises and the films are aligned as shown in FIG. The operation of lifting the rear side of the laver wrapping film F located at the position 5 is performed.

And the inner surface 11b 'of the said film edge part locking piece 11b is provided in parallel with the conveyance direction of the said conveyor 1 (refer FIG. 9, FIG. 13).

  As shown in FIG. 13, the tilting plate 11 is pivotally supported 13 at the rear end of the bearing plate 14 on the back side so as to be pivotable in the directions of arrows F and G at the upper end of the column 12, and on the back side of the horizontal plate 11a. A horizontal shaft 15 is pivotally supported between the pair of bearing plates 14 and 14 provided. The upper end of the drive arm 16 is pivotally supported at the center of the horizontal shaft 15, and the other end of the drive arm 16 is pivotally supported at one end of a crank 17 of the drive motor M3 (FIG. 13). reference). Therefore, when the drive motor M3 is rotationally driven (in the direction of arrow H, see FIG. 10), the drive arm 16 is moved up and down via the crank 17, whereby the tilt plate 11 is the same as the conveyor 1. It is configured to be able to reciprocate at a predetermined timing between two positions, a horizontal position of height and an inclined position inclined in the direction of arrow F from the horizontal position.

  The tilting angle of the tilting plate 11 is the same as the tilting angle of the lifting / lowering tilting plate 6 and tilts about 45 degrees in the direction of arrow G at the timing when the lifting / lowering tilting plate 6 is positioned upward. The inclined surface 6a of the up-and-down inclined plate 6 and the plate surface of the horizontal plate 11a of the tilting plate 11 are configured to be inclined at the same angle (see FIG. 4).

  At a position close to the tilting plate 11 on the downstream side of the tilting plate 11, a film position regulating plate 19 is fixed to the column 12 with a support angle 12 ′ in a direction perpendicular to the conveying direction of the conveyor 1. ing. As shown in FIG. 4, the film position regulating plate 19 includes a front projecting piece 19 a for regulating the position of the front side edge f <b> 1 on the downstream side of the laver packaging film F and the side portion on the downstream side of the laver packaging film F. A rear projecting piece 19b that restricts the position of the side edge f2 is provided. Then, as shown in FIG. 5, in the state where the up-and-down inclined plate 6 is raised and the inclined plate 11 is inclined and the laver wrapping film F is inclined, the film position adjusting movable plate 20 described later is moved in the arrow D direction. The front projecting piece 19a and the rear projecting piece 19b are in contact with the front side edge f1 and the side side edge f2 on the downstream side of the laver packaging film F, respectively. Positioning is performed in a direction orthogonal to the traveling direction.

  A film position adjusting movable plate 20 having substantially the same shape as the film position regulating plate 19 is provided on the upstream side of the tilting plate 11. The film position adjusting movable plate 20 is composed of an alignment plate 20a positioned in a direction perpendicular to the conveying direction of the conveyor 1, and a fixed plate 20b fixed to a retracting pin 21 ′ (FIG. 5) of the solenoid 21. A rear projecting piece that contacts the upstream side edge f2 ′ of the laver wrapping film F and presses the film F parallel to the conveying direction of the conveyor 1 (in the direction of arrow A). 20c and a front protrusion 20d that presses the film F parallel to the conveying direction of the conveyor 1 (in the direction of arrow A) by contacting the upstream side edge f1 ′ on the upstream side of the film F are formed. .

  The solenoid 21 is fixed to a fixed angle 21 "in an inclined state in which the solenoid 21 rises from the upstream side toward the downstream side. The film position adjusting movable plate 20 rises from the upstream side toward the downstream side. The fixed plate 20b is fixed to a protruding and protruding pin 21 ′ (FIG. 5) of the solenoid 21 that protrudes and protrudes along the inclined center line p. Therefore, when the solenoid 21 protrudes, the movable plate 20 moves to the inclined center line. As shown in FIG. 5, the rear projecting piece 20c and the front projecting piece 20d are inclined in the laver packaging film F by moving in the arrow D direction along the inclined center line p while rising along the p. The film F is slightly moved in the direction of arrow A (a direction orthogonal to the conveying direction of the conveyor 1) in contact with the upstream front side edge f1 ′ and the side part side edge f2 ′, and on the downstream side of the film F Front side By positioning f1 and the side edge f2 on the front protrusion 19a and the rear protrusion 19b of the position restricting plate 19, the film F is accurately positioned so as to be orthogonal to the conveying direction of the conveyor 1. Is.

  On the downstream side of the film alignment position 5, an air jet part 22 is provided adjacent to the alignment position 5. In the air injection section 22, an air injection pipe 23 is installed on the support section 23 ′ (FIG. 11) above the conveyor 1 and orthogonal to the traveling direction of the conveyor 1. A plurality of air injection holes 24 are provided at regular intervals on the left and right side surfaces of the air injection pipe 23 (FIG. 14), so that air of a predetermined pressure can be supplied to the air injection pipe 23 from the rear end. It is configured.

  Therefore, air is injected from the injection hole 24 of the air injection pipe 23 toward the upstream side (arrow a ′ direction) and the downstream side (arrow a direction) (see FIG. 8). In this air injection part 22, the laver wrapping film F temporarily stops just below the air injection pipe 23 as shown in FIG. At this time, the front end portion of the laver packaging film F is supported on a laver front end support plate 1d provided horizontally at the same height as the thin belt 1b.

  And by injecting air into the said pipe 23 at the timing when the said film F arrives just under the said pipe 23, air is injected to the upstream and downstream from the said injection hole 24, The said extension film of the said film F When the portions F1 and F2 are bent inward as shown by a two-dot chain line in FIG. 11, the bent extension film portions F1 and F2 are stretched in the left-right direction by the pressure of the air (FIG. 11 arrow).

  Thereafter, the conveyor 1 further moves intermittently in the direction of arrow A, and conveys the laver packaging film F to the laver packaging part (not shown) on the downstream side. In FIG. 1, reference numeral 25 denotes a U-shaped air shielding plate, and an upstream shielding plate 25 a and a downstream shielding plate 25 b are erected on the conveyor 1 with their lower ends close to each other. When the air shielding plate 25 injects air from the pipe 23, the other air-sealed packaging is located adjacent to the upstream and downstream sides of the seaweed packaging film F located in the air-injecting portion 22. This is for preventing the film F from being sprayed.

  Next, the electrical configuration of the present invention will be described. As shown in FIG. 16, the present invention includes a control unit (CPU or the like) 30 that operates each device in accordance with the operation procedure shown in FIG. The control unit 30 includes a motor M1 for driving the conveyor, a drive motor M2 for the laver suction unit 4, a drive motor M3 for the tilting plate 11, a solenoid 21, an air supply unit C1 including a compressor, and air to the air injection pipe 23. The air supply machine C2 which consists of a compressor etc. to introduce is connected, and the said control part 30 operates said each apparatus according to the operation | movement procedure shown in FIG.

Next, the operation of the present invention will be described with reference to the flowchart of FIG. Note that steps connected by a dotted line in FIG. 17 indicate steps having substantially the same timing.
First, it is assumed that the air supply machine C1 for the conveyor is operated and air is sucked from the small holes 1 ′ of the conveyor 1. The conveyor 1 is initially in a stopped state. The control unit 30 rotates the motor M2 for driving the laver suction part, raises the laver suction part 4, sucks one piece of the laver wrapping film F from the stocker 3 (FIG. 17P1-2), and lowers the thin belt. One laver wrapping film F is placed on 1a, 1b (FIG. 17P2-2, FIG. 3). At this time, the seaweed packaging film F is in a state of being adsorbed to the conveyor 1 by the air sucked from the small holes 1 ′ of the conveyor 1. At this time, at the film alignment position 5, steps P1-1 (up and down inclined plate 6 rising, tilting plate 11 tilting), P2-1 (solenoid drive), P3-1 (up and down tilting plate 6 lowering and tilting) in FIG. The operation up to the return of the plate 11 is performed.

  Next, the control unit 30 rotates the drive motor M1 to drive the conveyor 1 in the direction of arrow A to convey the laver wrapping film F to the alignment unit at the film alignment position 5 and temporarily stop (FIG. 17P4-1, FIG. 3). reference). At this time, the left and right extension film portions F1 and F2 of the film F are positioned above the elevating and tilting plate 6, the front end portion is positioned on the horizontal surface 11a of the tilting plate 11, and the front edge f3 of the film F is It exists in the position which opposes the film edge part latching piece 11b (position of FIG. 3).

  Next, the control unit 30 rotationally drives the drive motor M2 to raise the lifting and lowering tilting plate 6, and rotationally drives the drive motor M3 to tilt the tilting plate 11 forward (P1-1 and FIG. 4 through FIG. 17P5). reference). Then, the rear part including the extension film parts F1 and F2 of the laver packaging film F is released from the suction of the conveyor 1 as the elevating / lowering inclined plate 6 rises, and is lifted and inclined forward as shown in FIG. At this time, since the tilting plate 11 is also tilted forward at the same angle as the lifting / lowering tilting plate 6, the laver wrapping film F and the front surface (sloped surface 6a) of the lifting / lowering tilting plate 6 tilted at the same angle. It tilts forward while being placed on the horizontal surface 11a of the tilting plate 11, and as a result, the lower front edge f3 of the laver wrapping film F engages with the film end locking piece 11b, whereby the conveyor 1 The positional deviation in the front-rear direction (Q1 in FIGS. 15 (a) and 15 (b)) is corrected, and the positioning in the front-rear direction (direction perpendicular to the conveying direction of the conveyor 1) with respect to the conveyor 1 is accurately performed. On the other hand, the position F ′ of the front end portion (lower front edge) of the seaweed packaging film is accurately positioned (see FIGS. 15A and 15B).

  Next, the control unit 30 drives the solenoid 21 once (FIG. 17P2-1). When the solenoid 21 projects the projecting pin 21 ′, the film position adjusting movable plate 20 moves obliquely upward along the direction of arrow D, whereby the rear projecting piece 20c of the movable plate 20 is moved to the laver wrapping film F. The front protrusion 20d of the movable plate 20 abuts the upstream side edge f1 'of the laver wrapping film F to the upstream side edge f2' and presses the edge in the direction of arrow A (FIG. 4 to FIG. 5).

  As a result, the laver wrapping film F is slightly moved in the direction of arrow A along the film end locking piece 11b in the inclined state, and the side edge f2 and the front side on the downstream side of the film F The edge f1 is in contact with the rear protrusion 19b and the front protrusion 19a of the film position restricting plate 19 respectively, and thereby the film F is displaced in the rotational direction horizontally intersecting the conveyor 1 (FIG. 15B). (C) Q2) is corrected, and the side edge of the laver wrapping film F is positioned at an accurate position (solid line position in FIG. 15) perpendicular to the traveling direction of the conveyor 1.

  Next, the control unit 30 returns the solenoid 21 so that the film position adjusting movable plate 20 is separated from the upstream side of the seaweed packaging film F (the state of FIG. 17P2-1 and FIG. 6).

  Thereafter, the control unit 30 rotates the drive motor M2 to lower the up-and-down inclined plate 6 to a position below the conveyor 1, and rotationally drives the drive motor M3 to move the tilt plate 11 to the conveyor. And return to a position that is level with 1 (FIG. 17P3-1). Then, as shown in FIG. 7, the laver wrapping film F returns to the horizontal state after being accurately positioned in the above steps, and the rear side of the film F having the extended film portions F <b> 1 and F <b> 2 returns to the conveyor 1 again. Adsorbed. In this state, the laver wrapping film F is in a state where both the displacement in the front-rear direction and the displacement in the rotation direction with respect to the conveyor 1 are corrected as described above, and the accurate rice wrapping position in the subsequent rice wrapping process. Can be sent to.

  Next, the control unit 30 moves the conveyor 1 until the nori wrapping film F is located in the center of the nori wrapping film F, and the conveyor 1 is temporarily stopped at the position. (FIG. 8, FIG. 17P4-1).

  Then, the control part 30 supplies air to the said air injection pipe 23 via the air supply machine C2 (FIG. 17P1-3). Then, air is injected from the injection hole 24 of the injection pipe 23 toward the extension film portion F1 and the extension film portion F2 of the laver wrapping film F. Accordingly, if the extension film portions F1 and F2 are bent, the film portion F1 is pulled back to the upstream side and the film portion F2 is pulled back to the downstream side by the jet air, and the film portions F1 and F2 are bent. Is fixed.

  Then, the said control part 30 drives the conveyor 1 intermittently, and conveys the said laver packaging film F to the next rice packaging process (FIG. 17 P2-3). When the stop switch is pushed, the control unit 30 recognizes at step P5 and stops the apparatus.

  As described above, the present invention can accurately position a film material such as a laver wrapping film F with respect to the direction of travel of the conveyor. For example, the laver wrapping film F can be accurately conveyed without deviation until the rice wrapping process in the subsequent stage. The generation of defective packaging can be greatly suppressed.

  In addition, in a state in which a film material such as laver wrapping film F is inclined, the positional deviation in the width direction orthogonal to the conveyor conveyance direction and the positional deviation in the rotation direction in the direction intersecting the conveyor conveyance direction can be corrected. The corrected film F can be placed on the belt again.

  Further, a film material such as a laver wrapping film F can be always inclined at a constant angle, and an accurate positioning operation can be performed.

  In addition, since the film material such as laver wrapping film can be lifted and inclined from the upper surface of the belt and the film F can be positioned in an inclined state separated from the upper surface of the belt, the positioning operation can be performed without any trouble even in the suction type conveyor 1. It can be performed.

  Furthermore, bending of an extended film portion of a film material such as a laver packaging film can be corrected.

  Thus, according to the present invention, for example, when a film material such as a laver wrapping film F is conveyed on the conveyor 1, the film F can be accurately positioned with respect to the conveyor 1 in the conveyance process. In the subsequent packaging process, rice or the like can be accurately packaged, and the effect of greatly suppressing the occurrence of defective packaging can be achieved.

  In addition, the adsorption type conveyor 1 that adsorbs and conveys a film material such as a laver packaging film F with air or the like also exhibits an effect that the film material can be positioned without any trouble.

  In addition, the film F can be positioned only in the rectangular portion excluding the extension film portions F1 and F2 of the T-shaped seaweed packaging film F. Even if the extension film portions F1 and F2 are bent, the positioning of the film F is possible. Can be done accurately.

  The film material conveying device according to the present invention is widely used for various devices that require film material conveyance and positioning in addition to alignment of nori wrapping film in a rolled sushi production device or alignment of nori in a rice ball production device, for example. It is something that can be done.
