By driving the swing mechanism 12, the first support surface 111a, the second support surface 112a, and the third support surface 113a swing upward or downward integrally. The swing mechanism 12 is arranged rearwardly and downwardly of the first support plate 111 .

The rocking mechanism 12 has a rotating shaft 12a, an eccentric cam 12b, a rotating body 12c, a shaft body 12d, and a holding body 12e. The rotating shaft 12a is a shaft that rotates around an axis parallel to the width direction of the first conveying section 3A. The eccentric cam 12b is attached eccentrically to the rotating shaft 12a and rotates together with the rotating shaft 12a. In this embodiment, the rotor 12c is composed of a bearing. The rotor 12c has a circumferential surface that contacts the eccentric cam 12b. The shaft 12d is a shaft around which the first support plate 111 pivots. 12 d of shafts are arrange|positioned in parallel with the rotating shaft 12a. The shaft 12 d is inserted through a pair of projecting bodies 12 h projecting from the rear surface side of the first support plate 111 . Both ends of the shaft 12d are fixed to the side walls 7 (7L, 7R).

The holder 12e is arranged on the opposite side (back side) of the first support plate 111 from the first support surface 111a. The holder 12e has a holding shaft 12f and a pair of holding pieces 12g. The holding shaft 12f is arranged parallel to the rotating shaft 12a. The holding shaft 12f rotatably holds the rotor 12c. When the rotating body 12c is a bearing, the inner ring of the bearing is fixed to the holding shaft 12f, and the outer ring of the bearing is rotatable with respect to the holding shaft 12f (with respect to the inner ring) and contacts the eccentric cam 12b. A contact plate 12n is arranged on the rear surface side of the first support plate 111 so as to contact the rear surface of the first support plate 111 . The first support plate 111 and the contact plate 12n may be fixed (connected) or may be in contact without being fixed. The contact plate 12n and the first support plate 111 operate integrally.

A sprocket 12m for adjusting tension is meshed with the outer peripheral side of the chain 12j.

When the second sprocket 19c is rotated by driving the driving mechanism 19, which will be described later, the sprocket 12k rotates together with the connecting shaft 24. As shown in FIG. Rotation of the sprocket 12k is transmitted to the sprocket 12i through the chain 12j, the rotating shaft 12a rotates together with the sprocket 12i, and the eccentric cam 12b rotates.
As described above, the eccentric cam 12b is eccentrically attached to the rotor 12c. Therefore, as shown by the phantom line in FIG. 8, when the eccentric cam 12b rotates with the rotation of the rotary shaft 12a, the position (height) of the outer peripheral surface of the eccentric cam 12b changes. Along with this, the position (height) of the rotating body 12c, which has a circumferential surface that contacts the eccentric cam 12b, changes. As a result, the contact plate 12n and the first support plate 111 swing upward or downward about the shaft 12d together with the holder 12e that holds the rotor 12c. Further, the second support plate 112 and the third support plate 113 integrally formed with the first support plate 111 swing upward or downward. As a result, the first support surface 111a, the second support surface 112a, and the third support surface 113a swing upward or downward.

By swinging the first support surface 111a upward and downward by the swing mechanism 12 in this manner, a large number of headed vegetables stored in the container 11 and placed on the first support surface 111a can be loosened. . In addition, by swinging the second support surface 112a and the third support surface 113a upward and downward by the swing mechanism 12, the headed vegetables placed on the second support surface 112a and the third support surface 113a can be tilted along the inclination. can be moved onto the first support surface 111a. As a result, it becomes possible to smoothly convey the headed vegetables by the appropriate amount (in the case of the present embodiment, one by one) by the first conveying section 3A.

The first transport unit 3A transports the headed vegetables stored in the storage unit 11 one by one upward (from the bottom to the top) away from the first support surface 111a. The headed vegetables are conveyed forward by the first conveying section 3A as they go upward.
As shown in FIGS. 5, 9 to 11, etc., the first conveying section 3A has a moving body 15, a first plate 16, and a second plate 17. As shown in FIG.

A plurality of attachment bodies 20 are arranged side by side along the length direction of the first cable 15L and the second cable 15R (the transport direction A1 of the first transport section 3A). The plurality of mounting bodies 20 are arranged at predetermined intervals in the transport direction A1. The pitches (intervals) of the arrangement of the plurality of mounting bodies 20 are preferably set to be equal, but may be partially different. The pitch at which the mounting bodies 20 are arranged is set to be larger than the outer diameter of the head portion VG1 of the head vegetable VG.

As shown in FIG. 11 and the like, the mounting body 20 has a substrate 20a and a mounting portion 20b. A base end portion of the projecting portion 21 is fixed to the surface of the substrate 20a. Accordingly, the protruding portion 21 protrudes from the mounting body 20 . The back surface of the substrate 20a faces and abuts the surface (definition surface 22d) of the support member 22, which will be described later. The mounting portion 20b includes a first mounting portion 20b1 and a second mounting portion 20b2. The first attachment portion 20b1 extends from the left end portion of the substrate 20a while being bent at right angles. The second attachment portion 20b2 extends from the right end portion of the substrate 20a while being bent at right angles. The first attachment portion 20b1 and the second attachment portion 20b2 are arranged in parallel. The first attachment portion 20b1 is attached to one of the two cords (first cord 15L). The second attachment portion 20b2 is attached to the other of the two cords (second cord 15R).

As described above, the projecting portion 21 protrudes from the mounting body 20 and is attached to the moving body 15 via the mounting body 20 . As a result, the projecting portion 21 moves together with the mounting body 20 and the moving body 15 . The protruding portion 21 protrudes in a direction away from the moving body 15 so as to support the headed vegetable (specifically, the headed portion VG1 of the headed vegetable VG).
The projecting portion 21 is composed of a columnar or cylindrical rod. However, the shape of the projecting portion 21 is not limited to this. The projecting portion 21 includes two projecting portions spaced apart in the device width direction. The two projections are one projection 21L arranged on one side in the device width direction (first cord body 15L side) and the other projection arranged on the other side in the device width direction (second cord body 15R side). 21R. The distance between the one protruding portion 21L and the other protruding portion 21R is set smaller than the outer diameter of the headed portion VG1 of the headed vegetable VG.

As shown in FIGS. 9 and 11, the support member 22 is arranged between the first cord 15L and the second cord 15R. The support member 22 is arranged between the first mounting portion 20b1 and the second mounting portion 20b2 of the mounting body 20. As shown in FIG. The support member 22 extends along the conveying direction A1 of the first conveying section 3A, and extends from the starting end to the terminal end of the first conveying section 3A in the conveying direction A1. The starting end in the conveying direction A1 is the portion where conveyance of the headed vegetables is started in the first conveying portion 3A, and the terminal end in the conveying direction A1 is the portion where the conveying of the headed vegetables ends in the first conveying portion 3A (first This is the portion where headed vegetables are discharged from the conveying portion 3A.

Specifically, the starting end is located at the upper portion (upper side of the loop) of the loop-shaped movement path of the moving body 15 in a side view, where the movement path extends linearly from the arc-shaped path (the portion wound around the second sprocket 19c). It is in the vicinity of a change point where the path changes. The end portion is located near the point of change from the linear path to the arcuate path (the portion wound around the first sprocket 19b) in the upper portion of the movement path of the moving body 15 (upper side of the loop).

As shown in FIGS. 9, 11, and 12, the support member 22 has an upper plate 22a, one side plate 22b, and the other side plate 22c. The upper plate 22a is arranged on the rear surface side of the substrate 20a of the mounting body 20. As shown in FIG. The one side plate 22b is bent downward from one side (left side) of the upper plate 22a in the device width direction. The other side plate 22c is bent downward from the other side (right side) of the upper plate 22a in the device width direction. One side plate 22b and the other side plate 22c extend parallel to each other.

The support member 22 has a defining surface 22d that defines the attitude of the projecting portion 21. As shown in FIG. 22 d of regulation surfaces are comprised from the surface of the upper plate 22a of the support member 22, and are arrange|positioned between the 1st cord 15L and the 2nd cord 15R. The defining surface 22d abuts against the back surface of the substrate 20a of the mounting body 20, thereby supporting the mounting body 20 so that the protruding portion 21 is in an upright state. In other words, the regulating surface 22d abuts against the rear surface of the substrate 20a of the mounting body 20, thereby regulating the protruding portion 21 in the upright posture. The protruding portion 21 protrudes from the mounting body 20 and extends in a direction away from the defining surface 22d in the upright state.

As shown in FIGS. 4, 5, 11, 12, and 14, the defining surface 22d includes a first defining surface 22d1 and a second defining surface 22d2. The first defining surface 22d1 is arranged on the upstream side (starting end side) of the first conveying section 3A in the conveying direction A1. Specifically, the first defining surface 22d1 is arranged in a range from the starting end portion to the middle portion in the transport direction A1 of the first transport portion 3A. The second defining surface 22d2 is arranged on the downstream side (terminating end side) of the first conveying section 3A in the conveying direction A1. Specifically, the second defining surface 22d2 is arranged in a range from the middle portion to the end portion in the transport direction A1 of the first transport portion 3A. Therefore, the boundary 22e between the first regulating surface 22d1 and the second regulating surface 22d2 is located in the middle of the first conveying section 3A in the conveying direction A1.

The second defining surface 22d2 is inclined with respect to the first defining surface 22d1. The inclination angle of the second defining surface 22d2 with respect to the first defining surface 22d1 is an obtuse angle. The inclination angle of the second defining surface 22d2 with respect to the first defining surface 22d1 is set, for example, within a range of 140° to 160° (preferably about 150°). The first defining surface 22d1 and the second defining surface 22d2 are inclined with respect to the horizontal plane so as to shift upward toward the front. The angle of inclination of the first defining surface 22d1 with respect to the horizontal plane is greater than the angle of inclination with respect to the horizontal plane of the second defining surface 22d2. For example, the tilt angle of the first defining surface 22d1 with respect to the horizontal plane is 40° to 50°, and the tilting angle of the second defining surface 22d2 with respect to the horizontal plane is 15° to 20°.

As shown in FIGS. 5 and 11 to 15, the support member 22 has an extension plate 22g extending forward and downward from the front end of the upper plate 22a. The upper surface (extension surface) of the extension plate 22g is bent from the front end portion of the second defining surface 22d2 and extends forward and downward. As shown in FIG. 12, the projecting portion 21 falls down when the mounting body 20 moves forward beyond the extension plate 22g (when it is no longer supported by the extension plate 22g). The movement of the projecting portion 21 will be explained later.

As shown in FIGS. 4 and 5, the first plate 16 and the second plate 17 extend in the transport direction A1 along the defining surface 22d. The first plate 16 and the second plate 17 are bent in the same manner as the regulation surface 22d at the middle portion in the transport direction A1. The first plate 16 has a bent portion 16c and the second plate 17 has a bent portion 17c. The bent portion 16c of the first plate 16 and the bent portion 17c of the second plate 17 are located slightly behind the position corresponding to the boundary portion 22e between the first defining surface 22d1 and the second defining surface 22d2 in the transport direction A1. there is

Hereinafter, the portion forward of the bent portion 16c of the first plate 16 is referred to as "first plate front portion 16a", and the portion rearward of the bent portion 16c is referred to as "first plate rear portion 16b". Further, a portion forward of the bent portion 17c of the second plate 17 is referred to as a "second plate front portion 17a", and a portion rearward of the bent portion 17c is referred to as a "second plate rear portion 17b". The first plate rear portion 16b and the second plate rear portion 17b extend along the slope of the first defining surface 22d1. The first plate front portion 16a and the second plate front portion 17a extend along the slope of the second defining surface 22d2.

As shown in FIGS. 4, 5, and 13, the first plate 16 has a first front extension portion 16d that bends from the front end of the first plate front portion 16a and extends forward and downward. The second plate 17 has a second front extending portion 17d that bends from the front end of the second plate front portion 17a and extends forward and downward. An extension plate 22g is arranged between the first extension portion 16d and the second extension portion 17d. The first forward extension 16d and the second forward extension 17d extend along the extension plate 22g.

As shown in FIG. 14, the upper portion (the upper side of the loop) of the moving body 15 (cords 15L and 15R) extends along the defining surface 22d, and is the boundary between the first defining surface 22d1 and the second defining surface 22d2. It is bent at a position corresponding to the portion 22e. A fifth sprocket 19f is arranged at the bent portion of the cords 15L and 15R. The moving body 15 changes so that the angle with respect to the horizontal plane becomes smaller at the position corresponding to the boundary portion 22e. As a result, the transport direction A1 changes from the direction of the arrow A11 to the direction of the arrow A12 (so that the angle of the transport direction A1 with respect to the horizontal plane becomes smaller) at the position corresponding to the boundary portion 22e.

As shown in FIG. 14, the regulating surfaces (the first regulating surface 22d1 and the second regulating surface 22d2) and the plurality of mounting bodies 20 are arranged between the tips of the projecting portions 21 adjacent to each other in the conveying direction A1 in the middle of the conveying direction A1. It constitutes an expansion mechanism that expands the interval between. The extension mechanism will be described below.
The support member 22 supports the mounting body 20 so that the projecting portion 21 is in an upright state from the starting end portion to the terminal end portion of the first conveying portion 3A in the conveying direction A1. In the upright state, the projecting portion 21 is in a state of being raised in a direction perpendicular to the defining surface 22d. Since the second regulating surface 22d2 is inclined with respect to the first regulating surface 22d1, the mounting body 20 changes from being supported by the first regulating surface 22d1 to being supported by the second regulating surface 22d2. , the projecting direction of the projecting portion 21 changes. As a result, when the mounting body 20 is supported by the second defining surface 22d2, the distance L2 between the tips of the projections 21 adjacent to each other in the conveying direction A1 is It is larger than the interval L1 between the leading end portions of the projecting portions 21 adjacent to each other in the conveying direction A1 in the state where the protruding portions 21 are located. In other words, the distance between the leading ends of the protruding portions 21 adjacent in the transport direction A1 increases in the transport direction A1 at the intermediate portion in the transport direction A1.

As shown in FIG. 14 , in the middle portion of the conveying direction A1, the distance between the tips of the projecting portions 21 adjacent to each other in the conveying direction A1 is widened, so that a plurality of balls are formed between the projecting portions 21 adjacent to each other in the conveying direction A1. Even if the vegetables VG are pinched (clogged) and conveyed, a gap GP is generated between the headed vegetables VG and the projecting portion 21 on the upper side. Therefore, the state in which the headed vegetables VG are sandwiched (clogged) between the adjacent projecting parts 21 is eliminated, and the unnecessary headed vegetables VG on the upper side that are not directly supported by the projecting parts 21 are dropped from the projecting parts 21. be able to. As a result, it becomes possible to reliably and smoothly convey the head vegetables VG in appropriate amounts (for example, one by one).

In addition, the mounting body 20 and the support member 22 constitute a posture changing mechanism in which the protruding portion 21 is in an upright state from the starting end portion to the terminal end portion in the conveying direction A1, and the protruding portion 21 is in a collapsed state at the terminal end portion. there is The posture changing mechanism will be described below.
The attachment body 20 is rotatably attached to the moving body 15 . As shown in FIGS. 11 and 12, the attachment portion 20b of the attachment body 20 is attached to a fixture 15a fixed to the moving body 15 via a pivot 15b. The mounting portion 20b is rotatable together with the projecting portion 21 with the pivot 15b as a fulcrum. As a result, the protruding portion 21 is attached to the moving body 15 so that the posture can be changed between the standing state and the lying state. As shown in FIG. 12, the mounting body 20 rotates about the pivot 15b to change the attitude of the projecting portion 21 from the upright state to the laid down state. In FIG. 12, reference numeral 21a denotes the projecting portion 21 in the standing state, reference numeral 21c denotes the projecting portion in the lying down state, and reference numeral 21b denotes the projecting portion which has started to shift from the standing state to the lying state.

The supporting member 22 supports the mounting body 20 by restricting the rotation of the mounting body 20 so that the projecting portion 21 is in an upright state. , the mounting body 20 is allowed to rotate. The support member 22 supports (restricts rotation of) the mounting body 20 from the starting end to the terminal end of the first transporting section 3A in the conveying direction A1, and releases the support (rotating) of the mounting body 20 at the terminal end. movement).

As shown in FIG. 12, the movement path of the moving body 15 is a path that gradually descends forward after passing the terminal end in the conveying direction A1. As a result, when the support by the support member 22 is released after passing the terminal end in the conveying direction A1, the projecting portion 21 assumes a forward tilting posture and moves forward and downward while increasing the forward tilting angle.
Therefore, the projecting portion 21 is in an upright state (see the projecting portion 21a in FIG. 12) in the section where the mounting body 20 is supported by the support member 22 (the section extending from the starting end to the terminal end in the conveying direction A1). In the section where the mounting body 20 is not supported by the support member 22 (the section past the terminal end in the conveying direction A1), the action of gravity causes the mounting body 20 to fall forward and downward (forward in the conveying direction A1) and fall down (see the projecting portion 21c in FIG. 12). ).

The protruding portion 21 lowers the position of the tip portion when the standing state is shifted to the lying state. As a result, when the outer leaves VG2 and the roots VG3 of the head vegetable VG are entangled with the protrusions 21, the protrusions 21 can be pulled out (releasing) downward from the outer leaves VG2 and the roots VG3.
In this way, even if the outer leaves VG2 and the roots VG3 of the headed vegetables VG are entangled with the projecting portion 21, the projecting portion 21 falls down at the terminal end portion of the first conveying portion 3A in the conveying direction A1 and becomes a lodged state. , the projecting portion 21 can be smoothly separated from the outer leaf VG2. Therefore, it is possible to reliably discharge the headed vegetables VG toward the equipment (second conveying device 2B) of the next process without damaging them.

As shown in FIGS. 4, 5, 13, 15 to 18, etc., the first conveying device 2A includes a discharging portion 25 for discharging headed vegetables from the terminal end of the first conveying portion 3A in the conveying direction A1. ing. The discharging section 25 is inclined downward toward the second conveying device 2B, and discharges the headed vegetables upstream in the conveying direction A2 of the second conveying section 3B. Therefore, the discharge section 25 is also a supply section that supplies headed vegetables to the second transport section 3B.

As shown in FIGS. 13 and 15 to 18, the discharge portion 25 includes an inclined plate 25a, a first side plate 25b, a second side plate 25c, passages (first passage 25d, second passage 25e), and a first standing wall 25f. , and a second upright wall 25g.
The inclined plate 25a extends so as to be inclined downward (as it goes forward) away from the end portion of the first conveying portion 3A in the conveying direction A1. A surface (upper surface) 25i of the inclined plate 25a is an inclined surface. The inclined surface constitutes a rolling surface 25i on which the headed portion VG1 of the headed vegetable VG rolls along the inclination. As shown in FIGS. 13 and 15, the inclined plate 25a is attached to the front wall 9 via a downward extending portion 25h extending downward from the inclined plate 25a. The inclined surface (rolling surface) 25i of the inclined plate 25a is arranged in front of the support member 22 with a space therebetween. Thus, a gap G1 is formed between the inclined surface (rolling surface) of the inclined plate 25a and the support member 22. As shown in FIG. The gap G1 is formed when the mounting body 20 moves together with the moving body 15 and crosses the terminal end of the first conveying section 3A in the conveying direction A1, and the support of the mounting body 20 by the supporting member 22 is released (the projecting portion 21 collapses). This is a gap for the mounting body 20 to pass through (allowing the protruding portion 21 to fall down) when the protruding portion 21 is brought into the above state. In other words, the mounting body 20 passes through the gap G1 when the projecting portion 21 shifts from the upright state to the collapsed state.

The gap G1 communicates with the passages (first passage 25d, second passage 25e). The gap G1, the first passage 25d, and the second passage 25e are connected in a substantially U shape in plan view.
The inclined plate 25a is composed of a rear inclined plate 25a1 and a front inclined plate 25a2.
The rear inclined plate 25a1 is arranged in front of the support member 22 (in front of the extended plate 22g) and between the first forwardly extending portion 16d and the second forwardly extending portion 17d. The rear inclined plate 25a1 is arranged in front of the support member 22 with a space therebetween. As a result, the inclined surface (rear rolling surface) 25i1 of the rear inclined plate 25a1 is arranged in front of the support member 22 with a gap therebetween.

The front inclined plate 25a2 is arranged in front of the rear inclined plate 25a1. The inclined surface (front rolling surface) 25i2 of the front inclined plate 25a2 is located in front of the inclined surface (rear rolling surface) 25i1 of the rear inclined plate 25a1 and close to the inclined surface (rear rolling surface) 25i1. are placed. The inclination of the rear rolling surface 25i1 and the inclination of the front rolling surface 25i2 may be the same, or the inclination of the front rolling surface 25i2 may be larger than the inclination of the rear rolling surface 25i1. Incidentally, the rear inclined plate 25a1 and the front inclined plate 25a2 may be connected and integrated.

The first side plate 25b extends along the inclination of the inclined plate 25a on one side (left side) in the width direction (device width direction) of the inclined plate 25a. The second side plate 25c extends along the slope of the inclined plate 25a on the other side (right side) in the width direction (device width direction) of the inclined plate 25a. The first side plate 25b is composed of a rear first side plate 25b1 and a front first side plate 25b2. The second side plate 25c is composed of a rear second side plate 25c1 and a front second side plate 25c2. The rear first side plate 25b1 is attached to the first forward extension 16d. The rear second side plate 25c1 is attached to the second forward extension 17d. The front first side plate 25b2 is attached to the left portion of the front wall 9 via a downward extending portion 23L extending downward from the front first side plate 25b2. The front second side plate 25c2 is attached to the right portion of the front wall 9 via a downward extending portion 23R extending downward from the front second side plate 25c2. Thus, the front first side plate 25b2 extends from the first plate 16, and the front second side plate 25c2 extends from the second plate 17. As shown in FIG. The front first side plate 25b2 and the rear first side plate 25b1 may be integrated, and the front second side plate 25c2 and the rear second side plate 25c1 may be integrated.

The passages (first passage 25d, second passage 25e) are provided on the sides (one side and the other side in the device width direction) of the inclined surface 25a. The passages (the first passage 25d and the second passage 25e) are passed when the protruding portion 21 shifts from the upright state to the collapsed state.
The first passage 25d is a space (slit) formed between the inclined plate 25a and the first side plate 25b. The first passage 25d is composed of a rear first passage 25d1 and a front first passage 25d2. The rear first passage 25d1 is formed between the rear inclined plate 25a1 and the rear first side plate 25b1. The front first passage 25d2 is formed between the front inclined plate 25a2 and the front first side plate 25b2. The one protrusion 21L passes through the first passage 25d when the mounting body 20 passes through the gap G1 and the protrusion 21 is in the collapsed state.

The second passage 25e is a space (slit) formed between the inclined plate 25a and the second side plate 25c. The second passage 25e is composed of a rear second passage 25e1 and a front second passage 25e2. The rear second passage 25e1 is formed between the rear inclined plate 25a1 and the rear second side plate 25c1. The front second passage 25e2 is formed between the front inclined plate 25a2 and the front second side plate 25c2. The other protrusion 21R passes through the second passage 25e when the mounting body 20 passes through the gap G1 and the protrusion 21 falls down.

The headed vegetables VG conveyed by the first conveying unit 3A are discharged when the support of the mounting body 20 by the supporting member 22 is released (the protruding portion 21 is in a collapsed state) beyond the terminal end in the conveying direction A1. It is discharged from the section 25 . Specifically, as shown in FIGS. 16 and 24, the headed vegetable VG leaves the projecting portion 21 and moves forward and downward while rolling on the rolling surface 25i along the slope of the inclined plate 25a. At this time, the outer leaf VG2 or the root VG3 of the head vegetable VG can pass through (invade) the first passage 25d or the second passage 25e. Therefore, the rolling of the head portion VG1 is not hindered by the outer leaf VG2 or the root VG3, and the head vegetable VG is smoothly moved (rolled) and transferred to the next process equipment (second conveying device 2B). be able to.

The first upright wall 25f rises from the other side (left side) of the first side plate 25b in the device width direction and extends along the slope of the inclined plate 25a. The first standing wall 25f is composed of a front first standing wall 25f2 and a rear first standing wall 25f1. The front first upright wall 25f2 rises from the other side (left side) of the front first side plate 25b2 in the device width direction. The rear first upright wall 25f1 rises from the other side (left side) of the rear first side plate 25b1 in the device width direction. In this embodiment, the front first upright wall 25f2 and the rear first upright wall 25f1 are separated from each other by being formed of different members, but they may be formed continuously by one member.

The second upright wall 25g rises from one side (right side) of the second side plate 25c in the device width direction and extends along the slope of the inclined plate 25a. The second upright wall 25g is composed of a front second upright wall 25g2 and a rear second upright wall 25g1. The front second upright wall 25g2 rises from one side (right side) of the front second side plate 25c2 in the device width direction. The rear second upright wall 25g1 rises from one side (right side) of the rear second side plate 25c1 in the device width direction. In this embodiment, the front second upright wall 25g2 and the rear second upright wall 25g1 are separated from each other by being formed of different members, but they may be formed continuously by one member.

Since the discharge part 25 has the first standing wall 25f and the second standing wall 25g, the headed vegetables VG can be pushed to the side (left or right) of the discharge part 25 while rolling on the rolling surface 25i. You can prevent it from falling out.
The distance between the first upright wall 25f and the second upright wall 25g differs between the relatively near side and the far side with respect to the end portion of the first conveying portion 3A in the conveying direction A1. Specifically, the distance between the front first upright wall 25f2 and the front second upright wall 25g2 is wider than the distance between the rear first upright wall 25f1 and the rear second upright wall 25g1. As a result, it is possible to more reliably prevent the headed vegetables VG from falling while rolling on the rolling surface 25i.

The discharge portion 25 has a first extending wall 25j formed continuously with the first standing wall 25f and a second extending wall 25k formed continuously with the second standing wall 25g. . The first extended wall 25j bends from the rear end portion of the rear first upright wall 25f1 and extends toward one side (leftward) in the device width direction. The second extended wall 25k is bent from the rear end portion of the rear second upright wall 25g1 and extends toward the other side (rightward) in the device width direction.

FIG. 19 shows another embodiment of the discharge section 25. As shown in FIG. Other embodiments will be described below with respect to the differences from the above-described embodiment.
In the discharge part 25 of another embodiment, the inclined plate 25a is composed of one member. That is, the configuration is such that the rear inclined plate 25a1 and the front inclined plate 25a2 in the above embodiment are integrated. The first side plate 25b and the second side plate 25c are not provided. The first standing wall 25f is fixed to the first forward extending portion 16d via the first fixing plate 26L. The second standing wall 25g is fixed to the second forward extending portion 17d via a second fixing plate 26R. Each of the first upright wall 25f and the second upright wall 25g is composed of one member. That is, the front first upright wall 25f2 and the rear first upright wall 25f1 in the above embodiment are formed continuously by one member, and the front second upright wall 25g2 and the rear second upright wall 25g1 are formed by one member. It is a configuration formed continuously by members.

The first upright wall 25f and the second upright wall 25g extend longer than the inclined plate 25a in the direction away from the terminal end of the first transport section 3A in the transport direction A1 (forward and downward). As a result, the headed vegetables VG can be guided from the side by the first upright wall 25f and the second upright wall 25g until the headed vegetables VG finish rolling on the rolling surface 25i of the inclined plate 25a. The vegetables VG can be reliably discharged toward the equipment (second conveying device 2B) of the next process.

The first upright wall 25f extends longer than the second upright wall 25g in the direction away from the terminal end of the first transport section 3A in the transport direction A1 (forward and downward). The first upright wall 25f is arranged on the upstream side (starting end side) in the transport direction A2 of the second transport section 3B from the second upright wall 25g. Therefore, the headed vegetables discharged from the discharging part 25 to the second conveying part 3B are prevented from moving toward the upstream side in the conveying direction A2 by the first standing wall 25f, and smoothly move toward the downstream side (end side). be transported.

The distance between the first upright wall 25f and the second upright wall 25g differs between the relatively near side and the far side with respect to the end portion of the first conveying portion 3A in the conveying direction A1. Specifically, the distance between the first upright wall 25f and the second upright wall 25g is wide on the side relatively close to the terminal end in the transport direction A1 and narrow on the side far from it. More specifically, the distance between the front first upright wall 25f2 and the front second upright wall 25g2 gradually narrows away from the terminal end in the transport direction A1. As a result, the headed vegetables VG can be reliably received from the end portion of the first conveying portion 3A in the conveying direction A1. The rear first upright wall 25f1 and the rear second upright wall 25g1 are arranged parallel to each other with a constant distance therebetween. The interval between the rear first upright wall 25f1 and the rear second upright wall 25g1 is narrower than the interval between the front first upright wall 25f2 and the front second upright wall 25g2.

A second forwardly extending portion 17d of the second plate 17 is formed with an extended portion 17e that gradually expands in a direction approaching the first plate 16 from rear to front. Due to the formation of the expanded portion 17e, when the headed vegetable VG moves from the support member 22 to the rolling surface 25i, the headed vegetable VG is pushed at three points: the support member 22, the rolling surface 25i, and the expanded portion 17e. Supported. As a result, the head vegetable VG can be smoothly and reliably transferred from the support member 22 to the rolling surface 25i. It should be noted that the first forward extending portion 16d of the first plate 16 may be formed with an expanded portion that gradually expands in a direction approaching the second plate 17 from the rear toward the front.

The first passage 25d is formed between the first forward extension 16d and the inclined plate 25a. The second passage 25e is formed between the second forward extension 17d and the inclined plate 25a. The width of the first passage 25d and the width of the second passage 25e are different. Specifically, the width of the first passage 25d is wider than the width of the second passage 25e.
Next, the 2nd conveying apparatus 2B is demonstrated.

As shown in FIG. 1, the second conveying device 2B is arranged downstream of the first conveying device 2A in the conveying direction A1. As shown in FIGS. 1, 4, 17, 18, etc., the second conveying device 2B is arranged so as to overlap the discharging section 25 of the first conveying device 2A. The 2nd conveying apparatus 2B has the 2nd conveying part 3B which receives and conveys the head vegetables discharged|emitted from the discharge part 25 of 2 A of 1st conveying apparatuses.

As shown in FIGS. 17, 18, and 20 to 23, the second transport section 3B has two rollers 30A and 30B arranged in parallel. Of the two rollers 30A and 30B, one roller (hereinafter referred to as "first roller 30A") is arranged on the rear side (first conveying device 2A side), and the other roller (hereinafter referred to as "second roller 30B") ) is arranged on the front side (the side opposite to the first conveying device 2A). In this embodiment, there are two rollers, but there may be three or more, for example, four rollers may be arranged in parallel.

The two rollers 30A, 30B are arranged between the front wall plate 31 and the rear wall plate 32. As shown in FIG. The front wall plate 31 is arranged in the front part of the second transfer device 2B, and the rear wall plate 32 is arranged in the rear part of the second transfer device 2B. The front wall plate 31 and the rear wall plate 32 are attached to the second frame 6B.
The rotation axis of the first roller 30A (hereinafter referred to as "first rotation axis 33A") and the rotation axis of the second roller 30B (hereinafter referred to as "second rotation axis 33B") are arranged parallel to each other. . In FIGS. 18 and 20, the central axis of the first rotating shaft 33A is indicated by a dashed line CLA, and the central axis of the second rotating shaft 33B is indicated by a dashed line CLB. The length of the first roller 30A (the length in the direction of the first rotating shaft 33A) and the length of the second roller 30B (the length in the direction of the second rotating shaft 33B) are equal.

As shown in FIG. 20, the first roller 30A and the second roller 30B are inclined so as to gradually decrease from the upstream side (starting end side) toward the downstream side (terminating end side) in the conveying direction A2 of the second conveying portion 3B. are doing. The inclination of the first roller 30A (the inclination angle of the central axis CLA of the first roller 30A with respect to the horizontal line) is equal to the inclination of the second roller 30B (the inclination angle of the central axis CLB of the second roller 30B with respect to the horizontal line). The inclination of the first roller 30A and the inclination of the second roller 30B are set, for example, within a range of 5° to 10° (5° as an example).

As shown in FIG. 21, a drive mechanism 35 that rotates the first roller 30A and the second roller 30B is provided on one side (left side) of the first roller 30A and the second roller 30B in the rotation axis direction. The drive mechanism 35 has a motor 35a, a drive sprocket 35b, a driven sprocket 35c, a chain 35d, a transmission shaft 35e, a first bevel gear 35f, a second bevel gear 35g, a third bevel gear 35h, and a fourth bevel gear 35i.

The drive sprocket 35b is attached to the rotating shaft of the motor 35a. A chain 35d is stretched between the driving sprocket 35b and the driven sprocket 35c. A driven sprocket 35c, a first bevel gear 35f, and a second bevel gear 35g are attached to the transmission shaft 35e. A third bevel gear 35h is attached to the first rotating shaft 33A. A fourth bevel gear 35i is attached to the second rotating shaft 33B. The third bevel gear 35h meshes with the first bevel gear 35f. The fourth bevel gear 35i meshes with the second bevel gear 35g.

When the motor 35a is driven, the drive sprocket 35b rotates together with the rotating shaft of the motor 35a. Rotation of the drive sprocket 35b is transmitted to the driven sprocket 35c via the chain 35d, and the driven sprocket 35c rotates. When the driven sprocket 35c rotates, the first bevel gear 35f and the second bevel gear 35g rotate together with the transmission shaft 35e. The rotation of the first bevel gear 35f rotates the third bevel gear 35h, thereby rotating the first rotating shaft 33A. The rotation of the second bevel gear 35g causes the fourth bevel gear 35i to rotate, thereby rotating the second rotating shaft 33B. The first bevel gear 35f and the second bevel gear 35g are mounted in opposite directions, the first bevel gear 35f meshing with the front side of the third bevel gear 35h, and the second bevel gear 35g meshing with the rear side of the fourth bevel gear 35i.

By driving the drive mechanism 35, the first roller 30A and the second roller 30B are rotated inward (opposing sides face downward). As a result, the outer leaves VG2 of the headed vegetables VG can be pulled in and sandwiched between the first roller 30A and the second roller 30B (see FIG. 22). The second conveying unit 3B sandwiches the outer leaves VG2 of the headed vegetables VG between two rollers (between the first roller 30A and the second roller 30B), The headed vegetables VG are transported in the direction of the rotating shaft 33B) (transportation direction A2).

As shown in FIG. 23 and the like, the first roller 30A has a first roller body 30A1, a ridge portion 30A3, and a first brush portion 30A2. The first roller body 30A1 is a cylindrical or columnar member having a first rotating shaft 33A.
The ridge portion 30A3 protrudes from the surface of the first roller main body 30A1 and is spirally provided along the surface of the first roller main body 30A1. The spiral direction of the protrusion 30A3 is from the inner side (second roller 30B side) of the first roller 30A to the outer side (second roller 30B side). The ridge portion 30A3 is made of an elastic material such as rubber or soft synthetic resin. The ridge portion 30A3 is configured by, for example, spirally winding a string-like member (a rubber string, a rubber tube, etc.) made of an elastic material around the surface of the first roller body 30A1.

The first brush portion 30A2 protrudes like a brush from the surface of the first roller main body 30A1. The first brush portion 30A2 is configured by arranging a plurality of hair bundles arranged in a spiral. A plurality of tufts of bristles that constitute the first brush portion 30A2 are planted in a number of holes that are spirally arranged in the surface of the first roller body 30A1, and protrude from the surface of the first roller body 30A1. The first brush portion 30A2 and the ridge portion 30A3 alternately appear along the direction of the central axis CLA of the first roller 30A (conveyance direction A2). In other words, the first brush portion 30A2 is provided between the ridges 30A3 adjacent to each other with an interval in the transport direction A2.

As shown in FIG. 18, in the length direction (conveyance direction A2) of the first roller 30A, the width W1 of the region where the first brush portion 30A2 is provided is larger than the width W2 of the ridge portion 30A3. As shown in FIG. 21, the height of the ridge portion 30A3 (the height from the surface of the first roller main body 30A1) is higher than the height of the first brush portion 30A2.
As shown in FIG. 23, the second roller 30B has a second roller body 30B1 and a second brush portion 30B2. The second roller body 30B1 is a cylindrical or columnar member having a second rotating shaft 33B. The second brush portion 30B protrudes like a brush from the surface of the second roller main body 30B1. The second brush portion 30B is configured by arranging a plurality of hair bundles arranged in a spiral. A plurality of tufts of bristles forming the second brush portion 30B are planted in a large number of holes formed spirally on the surface of the second roller body 30B1, and protrude from the surface of the second roller body 30B1.

A protrusion amount LB of the second brush portion 30B from the surface of the second roller body 30B1 is larger than a protrusion amount LA of the first brush portion 30A2 from the surface of the first roller body 30A1. As a result, the tufts of bristles forming the second brush portion 30B are easier to deform (bend) than the tufts of bristles forming the first brush portion 30A2.
When the first roller 30A and the second roller 30B rotate inward, the headed vegetables VG are transported in the transport direction A2 while being placed on the first roller 30A by the spiral of the protrusion 30A3. The conveying speed (moving speed in the conveying direction A2) of the second conveying portion 3B is higher than the conveying speed (moving speed in the conveying direction A1) of the first conveying portion 3A. As a result, it is possible to prevent the headed vegetables conveyed from the first conveying section 3A from accumulating on the upstream side of the second conveying section 3B.

In the case of this embodiment, the first roller 30A has the ridge portion 30A3 and the second roller 30B does not have the ridge portion, but the second roller 30B has the same ridge portion as the first roller 30A. It is good also as a structure which has. In this case, the ridge portion of the second roller 30B is provided in a spiral shape extending in the same direction as the spiral arrangement of the tufts of the second brush portion 30B.
Two rollers (first roller 30A, second roller 30B) are such that the height H1 of the upper surface of one roller (first roller 30A) is higher than the height H2 of the upper surface of the other roller (second roller 30B). are arranged with a height difference (H2-H1) that is lower than the This height difference is a height difference obtained by comparing the heights of the upper surfaces of the two rollers at the same position in the conveying direction A2. The height of the upper surface of the roller is the height from the installation surface of the highest position of the roller at a specific position in the conveying direction A2. Specifically, the height of the upper surface of the first roller 30A is the height from the mounting surface of the upper end of the protrusion 30A3 at a specific position in the conveying direction A2, and the height of the upper surface of the second roller 30B is It is the height from the installation surface of the upper end of the second brush portion 30B2 at the same specific position in the transport direction A2. The height difference (H2-H1) is formed over the entire length in the transport direction A2.

In the case of this embodiment, as shown in FIGS. 23 and 22(a), the height difference (H2-H1) is determined by making the outer diameter of the first roller 30A smaller than that of the second roller 30B. It is formed by arranging the rotating shaft 33A below the second rotating shaft 33B.
However, the configuration for forming the height difference (H2-H1) is not limited to this. For example, as shown in FIG. 22(b), the height difference (H2-H1) equalizes the outer diameter of the first roller 30A and the outer diameter of the second roller 30B, and rotates the first rotating shaft 33A to the second rotation. It may be formed by arranging it below the shaft 33B. Further, as shown in FIG. 22(c), the height difference (H2-H1) is obtained by making the outer diameter of the first roller 30A smaller than the outer diameter of the second roller 30B, and rotating the first rotating shaft 33A to the second rotation. It may be formed by arranging it at the same height as the shaft 33B.

As shown in FIGS. 17, 18, 21 and 23, a guide plate 37 is provided above the first roller 30A. The guide plate 37 extends along the length direction (conveyance direction A2) of the first roller 30A. The guide plate 37 is inclined so as to gradually fall from the upstream side toward the downstream side in the transport direction A2.
The guide plate 37 has a first portion 37a and a second portion 37b. The first portion 37a and the second portion 37b are integrally formed side by side in the front-rear direction. The first portion 37a is arranged between the rear wall plate 32 and the first roller 30A in the front-rear direction. When viewed from the length direction (conveyance direction A2) of the first roller 30A, the front side (first roller 30A side) and the rear side (opposite side to the first roller 30A side) of the first portion 37a have the same height. is. The second portion 37b is inclined so as to become gradually lower from the front side to the rear side (as it approaches the first roller 30A).

As shown in FIG. 18, the discharge section (supply section) 25 of the first conveying device 2A is arranged on the left side of the guide plate 37 (the starting end side in the conveying direction A2). The discharge portion (supply portion) 25 has an inclined plate 25a, a first side plate 25b, and a second side plate 25c that extend above the guide plate 37. As shown in FIG. Of the inclined plate 25a, the first side plate 25b, and the second side plate 25c, only the first side plate 25b and the second side plate 25c may extend above the guide plate 37. FIG. In this case, the inclined plate 25a must extend at least forward of the rear wall plate 32. As shown in FIG.

As shown in FIG. 24, the discharge section (supply section) 25 supplies headed vegetables VG above the first roller 30A. More specifically, the discharge section (supply section) 25 supplies the headed vegetables VG above the first roller 30A from the direction perpendicular to the first rotating shaft 33A with respect to the first roller 30A. The headed vegetables VG discharged from the discharge part (supply part) 25 pass over the guide plate 37 and are supplied above the first roller 30A.

As shown in FIGS. 17, 18, 21 and 23, a guide member 38 is arranged above the second conveying section 3B. Specifically, the guide member 38 is arranged above the second roller 30B. The guide member 38 extends in the conveying direction A2 (longitudinal direction of the second roller 30B) and is arranged so as to gradually descend from the upstream side toward the downstream side in the conveying direction A2. The guide member 38 extends over a range from the starting end portion to the middle portion in the conveying direction A2. Specifically, the guide member 38 extends over a range from above the starting end (left end) of the second roller 30B to above the lengthwise middle portion. In the transport direction A2, the length of the guide member 38 is shorter than the length of the second roller 30B and longer than half the length of the second roller 30B. The terminal end (right end) of the guide member 38 is positioned to the right of the lengthwise middle portion of the second roller 30B.

The guide member 38 has a front plate portion 38a, an upper plate portion 38b, and a rear plate portion 38c. The front plate portion 38a is fixed to the second frame 6B in front of the second roller 30B and extends upward from the second frame 6B. The upper plate portion 38b extends rearward (toward the first roller 30A) from the upper end of the front plate portion 38a. The rear plate portion 38c extends rearward and downward from the rear end of the upper plate portion 38b. The surface of the rear plate portion 38c is an inclined surface 38d facing obliquely upward and rearward. The inclined surface 38d transitions from front to back as it extends downward. In other words, the inclined surface 38d transitions from the first roller 30A (one roller) side to the second roller 30B (the other roller) side as it extends upward. The lower end of the inclined surface 38d is positioned between the first rotating shaft 33A of the first roller 30A and the second rotating shaft 33B of the second roller 30B, and the height H1 of the upper surface of the first roller 30A and the height of the second roller 30B. It extends to a position lower than the height H2 of the upper surface of the second roller 30B.

As shown in FIG. 23, the headed vegetables VG discharged (supplied) from the discharge portion (supply portion) 25 above the first roller 30A collide with the guide member 38 and are prevented from moving toward the second roller 30B (forward). Therefore, it is placed mainly on the first roller 30A. At this time, the headed vegetables VG are allowed to tilt (roll) toward the second roller 30B by coming into contact with the inclined surface 38d of the guide member 38. As shown in FIG. Therefore, the impact when the headed vegetables VG hit the guide member 38 is alleviated, and the headed vegetables VG can be prevented from rebounding or being damaged. Further, since the lower end portion of the inclined surface 38d extends to the above-described low position, it is possible to prevent the headed vegetables VG from hitting the lower end portion of the inclined surface 38d and being damaged.

As shown in FIG. 24, the headed vegetables VG mainly placed on the first roller 30A are transported downstream in the conveying direction A2 along the guide member 38 while repeating rotation on the first roller 30A. and transported. Since the height of the upper surface of the first roller 30A is lower than the height of the upper surface of the second roller 30B, the headed vegetable VG becomes unstable and rotates. becomes easier.

The headed vegetable VG rotates (see arrow P1) in a direction orthogonal to the conveying direction A2 by the rotation of the first roller 30A and the second roller 30B, and the first roller 30A and the second roller 30B are inclined downward. Rotation (see arrow P2) around the conveying direction A2 is also performed. As the head vegetable VG rotates in multiple directions, there are many opportunities for the outer leaf VG2 to be in a downward posture.

When the outer leaves VG2 of the headed vegetables VG face downward, the outer leaves VG2 are drawn between the first roller 30A and the second roller 30B. As shown in FIG. 22, the headed vegetables VG whose outer leaves VG2 are drawn between the first roller 30A and the second roller 30B assume a downward posture in which the outer leaves VG2 face downward.
In this way, the headed vegetables VG assume a downward posture in which the outer leaves VG2 face downward while being conveyed by the second conveying section 3B. Then, the headed vegetables VG in the downward posture are transferred from the second conveying section 3C to the third conveying section 3C in the state of the downward posture.

Next, the 3rd conveyance part 3C is demonstrated.
As shown in FIGS. 1 and 2, the third transport section 3C is arranged downstream of the second transport section 3B in the transport direction A2. The third conveying unit 3C conveys the headed vegetables VG conveyed by the second conveying unit 3B further downstream (to the right).

A portion of the first pinching belt 71 and a portion of the second pinching belt 72 overlap in the conveying direction A3 of the third conveying portion 3C.

The first pinching belt 71 includes one side belt 71L and the other side belt 71R. The one-side belt 71L is arranged on one side of the third transport section 3C in a direction orthogonal to the transport direction A3 (hereinafter referred to as "third orthogonal direction"). The other side belt 71R is arranged on the other side in the third orthogonal direction. The one-side belt 71L and the other-side belt 71R are endless, and are wound around a plurality of pulleys.

As shown in FIG. 25, the fourth pulley 74 and the seventh pulley 77, and the fifth pulley 75 and the eighth pulley 78 are close to each other. As a result, the one-side belt 71L and the other-side belt 71R are in contact with each other. The one-side belt 71L and the other-side belt 71R move from the left to the right (toward the third conveying direction A3, which is the direction away from the second conveying section 3B) on the sides that contact each other.

As shown in FIGS. 25 and 28, the first pinching belt 71 pinches the outer leaves VG2 of the headed vegetables VG between the one-side belt 71L and the other-side belt 71R, and moves while pinching the outer leaves VG2. By doing so, the head vegetables VG are conveyed from the downstream side to the upstream side (in the conveying direction A3). When the headed vegetables VG are conveyed by the first pinching belt 71, the posture when transferred from the second conveying section 3B is maintained. That is, the posture of the headed vegetables VG conveyed by the first pinching belt 71 is a downward posture in which the outer leaves VG2 are downward.

The second pinching belt 72 conveys the headed vegetables VG conveyed by the first pinching belt 71 further downstream. The second pinching belt 72 is composed of one belt.

As shown in FIGS. 39 and 42 , the rotation drive mechanism 143 (hereinafter referred to as “first rotation drive mechanism 143 ”) has a motor 145 and a first transmission mechanism 146 .

The rotational driving force of the motor 145 is transmitted to the first shaft 141La and the second shaft 141Ra via the first transmission mechanism 146 . As a result, the first shaft 141La and the second shaft 141Ra rotate inward (the opposing sides face downward) about the central axis. As a result, the first rotating body 141L and the second rotating body 141R also rotate inward relative to each other around the central axis.

Subsequently, the first elastic plate 142L and the second elastic plate 142R move downward along the curved surface of the head portion VG1 while flexing and curving. (see virtual lines 142L2 and 142R2). As a result, the spread of the roots VG3 of the head vegetables VG can be suppressed and evened out. At this time, the outer leaves VG2 of the headed vegetables VG are firmly sandwiched between the wavy curved lower belts 93L and 93R. Therefore, it is possible to align the roots VG3 while preventing the headed vegetables VG from falling.

Next, the root pulling part 170 will be described.
The root pulling-in unit 170 pulls downward the roots VG3 of the headed vegetables VG conveyed by the fourth conveying unit 3D.

The first drawing roller 171L is fitted onto the first shaft 141La. The second pull-in roller 171R is fitted onto the second shaft 141Ra. The first pull-in roller 171L rotates around an axis (around the first shaft 141La) extending in the transport direction A4 of the fourth transport section 3D. The second pull-in roller 171R rotates around an axis (around the second shaft 141Ra) extending in the transport direction A4 of the fourth transport section 3D.

The rotational driving force of the motor 145 is transmitted to the first shaft 141La and the second shaft 141Ra via the first transmission mechanism 146 . As a result, the first shaft 141La and the second shaft 141Ra rotate inward (the opposing sides face downward) about the central axis. As a result, the first pull-in roller 171L and the second pull-in roller 171R rotate inward (opposing sides face down) around the central axis.

As shown in FIG. 43, the first pull-in roller 171L and the second pull-in roller 171R mutually rotate inwardly around the center axis, so that the root VG3 of the headed vegetable VG is pulled by the first pull-in roller 171L and the second pull-in roller 171L. It is drawn between 171R. At this time, as shown in FIG. 36, the outer leaves VG2 of the head vegetable VG are firmly sandwiched between the wavy curved lower belts 93L and 93R, so that the root VG3 of the head vegetable VG is positioned downward. It will be in a state of being extended linearly. As a result, even if the root VG3 of the head vegetable VG spreads downward, the root VG3 can be extended straight.

The head vegetable VG with the roots VG3 extended by the root pulling-in unit 170 is transported further downstream (to the right) in a suspended state with the outer leaves VG2 sandwiched by the lower belts 93L and 93R. and sent to the root cutting unit 180.

The center shaft 183La of the first feed roller 183L and the center shaft 183Ra of the second feed roller 183R are oriented vertically, and these center shafts 183La and 183Ra are located to the left of the center shaft 181a of the root cutting blade 181 (root pulling-in). 170 side). The outer peripheral surfaces of the first feed roller 183L and the second feed roller 183R are in contact with or close to each other on the inner sides (the sides facing each other), and rotate in opposite directions to each other (to the left on the sides facing each other). As shown in FIGS. 39 and 40, the position where the first feed roller 183L and the second feed roller 183R abut or come close to each other substantially coincides with the outer periphery of the root cutting blade 181 in the vertical direction.

The rotation direction of the first feed roller 183L and the second feed roller 183R is the direction from the left to the right (the same direction as the transport direction A4 of the fourth transport section 3D) on the side (inner side) that contacts or approaches each other. is.

The headed vegetable VG moves to the root feeding section 182 with the root VG3 stretched by the root pulling section 170, whereby the root VG3 is drawn between the first feeding roller 183L and the second feeding roller 183R. pinched. The root VG3 sandwiched between the first feed roller 183L and the second feed roller 183R is moved rightward (toward the root cutting blade 181) by the rotation of the first feed roller 183L and the second feed roller 183R. It is cut by the rotation of the cutting blade 181 .

Here, the moving speed of the root VG3 accompanying the rotation of the first feed roller 183L and the second feed roller 183R is faster than the transport speed of the fourth transport section 3D. That is, the rotation speed (peripheral speed) of the first feed roller 183L and the second feed roller 183R is faster than the moving speed of the lower belt 93L and the lower belt 93R.

According to this configuration, the vegetable head VG placed on the surfaces of the rollers 30A and 30B becomes unstable and easily rotates. Therefore, by repeating the rotation of the headed vegetables VG, the outer leaves VG2 are pulled downward between the one roller 30A and the other roller 30B in a short period of time, and the outer leaves VG are stabilized in the downward posture. As a result, the posture of the headed vegetables VG can be stabilized in a short conveying distance.

Further, one roller 30A and the other roller 30B are inclined so as to gradually decrease from the upstream side toward the downstream side in the transport direction A3 of the transport section 3B.
According to this configuration, the headed vegetables VG are rotated in the direction perpendicular to the conveying direction A2 by the rotation of the first roller 30A and the second roller 30B, and in addition, the first roller 30A and the second roller 30B are rotated. Since it is inclined downward, it also rotates around the conveying direction A2. As the head vegetables VG rotate in multiple directions, there are many opportunities for the outer leaves VG2 to face downward, and in a short period of time, the outer leaves VG2 face downward, and the rollers 30A and 30A are separated from each other. roller 30B.

Further, the conveying device (second conveying device) 2B includes a guide member 38 arranged above the conveying section 3B and extending in the conveying direction A3. It has an inclined surface 38d that transitions from the roller 30B to the other roller 30B.
According to this configuration, the headed vegetables VG are allowed to tilt (roll) toward the second roller 30B by contacting the inclined surface 38d of the guide member 38. As shown in FIG. Therefore, the impact when the headed vegetables VG hit the guide member 38 is alleviated, and the headed vegetables VG can be prevented from rebounding or being damaged.

In addition, the lower end of the inclined surface 38d is located between the rotating shaft (first rotating shaft) 33A of one roller 30A and the rotating shaft (second rotating shaft) 33B of the other roller 30B, and It extends to a position lower than the height of the upper surface of roller 30B and the height of the upper surface of the other roller 30B.
According to this configuration, it is possible to prevent the headed vegetables VG from hitting the lower end portion of the inclined surface 38d and being damaged.

Also, the outer diameter of one roller 30A is smaller than the outer diameter of the other roller 30B.
According to this configuration, it is possible to provide a height difference in which the height of the upper surface of one roller 30A is lower than the height of the upper surface of the other roller 30B.
Further, the rotating shaft 33A of one roller 30A is arranged below the rotating shaft 33B of the other roller 30B.

According to this configuration, it is possible to provide a height difference in which the height of the upper surface of one roller 30A is lower than the height of the upper surface of the other roller 30B.
Further, the conveying device (second conveying device) 2B includes a supply unit 25 that supplies headed vegetables VG to the conveying unit 3B, and the supply unit 25 supplies the headed vegetables VG above one roller 30A.
According to this configuration, the headed vegetables VG supplied above the one roller 30A by the supply unit 25 can be smoothly conveyed by the rotation of the one roller 30A.

The preparation device 1 also includes the conveying device 2 and a first cutting device 4 that cuts the roots VG3 of the vegetables VG conveyed by the conveying device 2 .
According to this configuration, the first cutting device 4 can cut the root VG3 of the vegetable VG conveyed by the conveying device 2 with the root VG3 facing downward. Therefore, the cutting process of the root VG3 of the vegetable VG can be performed satisfactorily.

The preparation device 1 also includes a second cutting device 5 that cuts the outer leaves VG2 of the vegetables VG conveyed by the conveying device 2 .
According to this configuration, the second cutting device 5 can cut the outer leaves VG2 of the vegetables VG conveyed by the conveying device 2 with the roots VG3 facing downward. Therefore, the outer leaf VG2 of the vegetable VG can be reliably cut.
