  Further, the first supply belt unit 13 and the second supply belt unit 17 are alternately arranged, the drive pulley 12 on the conveyance end side around which the endless belt of the first supply belt unit 13 is wound, and the second supply belt unit 17. By connecting the drive pulley 15 on the conveyance start end side around which the endless belt is wound to the same supply conveyor drive shaft 19, the conveyance end point of the first supply conveyor line 14 and the conveyance start end of the second supply conveyor line 18 are connected. Are overlapped in the transport direction. The supply conveyor drive shaft 19 is connected to a motor 20 which is a drive means of the supply conveyor, and drives the endless belts of the first supply conveyor line 14 and the second supply conveyor line 18 simultaneously by the motor 20.

  The first supply belt unit 13 and the second supply belt unit 17 are units in which pulleys are provided before and after the conveyance direction of the frame member extending in the conveyance direction, and endless belts are wound around the front and rear pulleys. The first supply belt unit 13 and the second supply belt unit 17 are attached to an apparatus main body frame (not shown).

  When a long article to be conveyed, for example, pepper, is supplied to the article conveyance conveyor 30 by the article supply conveyor 10, one piece is provided for the six rows of the first supply belt unit 13 and the second supply belt unit 17 shown in the figure. The pepper 60 is conveyed in a posture oriented in the width direction. In this case, also about the conveyance conveyor 30 and the articles | goods discharge conveyor 50, the single pepper 70 is similarly conveyed with the attitude | position which faced the width direction.

  The article conveying conveyor 30 is endless with a driven pulley 31 that is a rotation support means on the conveyance start end side, a drive pulley 32 that is a rotation support means arranged on the conveyance end side, and an intermediate pulley 33 that is a rotation support means arranged on the inclined upper end position. A conveyor belt line 36 is provided in which a plurality of conveyor belt units 35 around which a belt 34 is wound are arranged in parallel along the width direction. The conveyor belt unit 35 has a driven pulley 31, a drive pulley 32, and an intermediate pulley 33 attached to a frame 35 a extending in the conveyance direction. Each conveyor belt unit 35 has a conveyance start end side as a conveyance end side of the second supply belt unit 17. It is attached to the apparatus main body frame so as to overlap in the transport direction.

  In the present embodiment, the rotation axis of the driven pulley 31 is positioned on the drive shaft 19 rather than the rotation axis of the conveyance end pulley 16 of the second supply belt unit 17, and the second supply belt unit 17 arranged side by side. A conveyor belt unit 35 is disposed between the two. Further, the upper end of the driven pulley 31 of the transport belt unit 35 is positioned below the article transport surface of the second supply belt unit 17.

  The article discharge conveyor 50 includes a plurality of discharge belt units 53 each having an endless belt wound around a drive pulley 51 on the conveyance start end side and a pulley 52 on the conveyance end side, and arranged in parallel along the width direction. The discharge conveyor line 54 is provided, and the discharge belt units 53 and the conveyance belt units 35 are alternately arranged in the width direction. Further, the drive pulley 51 on the conveyance start end side around which the endless belt of the discharge belt unit 53 is wound and the drive pulley 32 on the conveyance end side around which the endless belt of the conveyance belt unit 35 is wound are connected to the same drive shaft 37 for the conveyance conveyor. By connecting to, the conveyance start end part of the discharge conveyor line 54 and the conveyance termination | terminus part of the conveyance conveyor line 36 are made to overlap in a conveyance direction. The conveyance conveyor drive shaft 37 is connected to a motor 38 which is a conveyance conveyor drive means, and the motor 38 drives the endless belts of the discharge conveyor line 34 and the conveyance conveyor line 36 simultaneously. The conveyance speed of the discharge conveyor line 54 rotated by the motor 38 is set to be equal to or slightly higher than the supply speed of the article supply conveyor line 10.

  In the present embodiment, the endless belt 34 constituting the transport belt unit 35 of the article transport conveyor 30 has an endless belt body 40 having the same width as the endless belt body 40 on the outer peripheral surface of the endless belt body 40 as shown in FIG. A plurality of corrugated corrugated beam portions 41, which are article supporting means that undulate along the conveying direction (longitudinal direction) of the belt main body 40, are formed at regular intervals. The corrugated beam 41 is formed by bending a flexible and elastically deformable belt-like member into a mountain shape having a height H, and bonding a trough to the outer peripheral surface of the endless belt body 40 with a hem width L in the longitudinal direction of the endless belt body 40. It is configured to be fixed with an agent. The belt-like member longer than the entire circumferential length of the endless belt main body 40 is made endless to form a frame-like corrugated crosspiece 41, and a trough therebetween is bonded and fixed to the outer peripheral surface of the endless belt main body 40 with an adhesive. May be.

  In addition, the endless belt body 40 is formed by the outer peripheral surface of the driven pulley 31 during the turning operation after the endless belt main body 40 in which the corrugated beam 41 is formed starts to wind around the driven pulley 31. The length of the corrugated beam portion 41 is set so that the space formed between the inner peripheral surface of the corrugated beam portion 41 and the outer peripheral surface of the endless belt main body 40 is maintained even when the main body 40 is curved in a convex shape. Has been.

While the portion of the endless belt main body 40 where the corrugated beam portion 41 is provided moves in the region where it is wound around the driven pulley 31, the corrugated beam portion 41 has a skirt on the front end side of the conveyance that is the outer shape of the driven pulley 31. If the waveform of the symmetrical shape along the conveyance direction starts to collapse, and moves to just half the position, the hem width when the corrugated beam portion 41 is moving on the straight conveyance path ( The linear distance L) is reduced to the diameter D of the driven pulley 31 (L> D). For this reason, the slope of the corrugated beam portion 41 is smaller than the slope angle (θ ₀ ) on the straight conveyance path. When the corrugated bar 41 further moves, the slope angle (θ ₁ ) of the front slope of the corrugated bar 41 gradually changes to return to the original slope angle (θ ₀ ). The slope on the front side of the crosspiece 41 is deformed so that the skirt is a fulcrum, and then returns to the original slope angle (θ ₀ ) through a horizontal posture position close to the horizontal. The state in which the slope on the front side of the corrugated bar 41 moves while changing the posture moves in such a way that the slope on the front side of the conveyance rises upward, and rises gradually forward in the conveyance direction after the horizontal posture. While moving up the slope.

  In the present embodiment, the article conveying surface of the second supply belt unit 17 is made to coincide with the height position at which the inclined surface of the corrugated beam portion 41 on the front side of the corrugated beam portion 41 becomes the horizontal posture position, and as described above, the conveying belt unit 35. This is why the upper end of the driven pulley 31 is positioned below the article transport surface of the second supply belt unit 17.

  A substantially horizontal posture of the corrugated beam 41 rising from below with respect to the pepper 70 that is the article to be conveyed that has been conveyed through the second supply belt unit 17 and has reached a delivery position that is an overlap portion with the conveyance belt unit 35. The inclined surface on the front side of the conveyance comes into contact, and the pepper 70 is supported so as to be lifted upward, and transferred to the conveyance belt unit 35. As the corrugated beam 41 passes through the position where the driven pulley 31 is wound and reaches the linear conveying path, the slope on the front side of the corrugated beam 41 rises and supports the pepper 70 on the back side in the conveying direction. Transport upward.

  In the present embodiment, when the shape of the corrugated beam portion 41 forming the corrugated protrusion on the horizontal conveyance path is a basic shape, the height H to the top of the corrugated beam portion 41 in the basic shape is at least higher than the height of the center of gravity of the conveyed article. The height is set high so as to reliably support the conveyed article in the inclined article conveying section 30a. Further, the height H of the corrugated bar 41 is set to be twice or less the height of the conveyed article. This is because, when the height H is too high, the corrugated beam portion 41 is bent too much when the conveyed article is supported at the delivery position of the conveyed article, and the driven pulley cannot be supported. When the corrugated beam portion 41 moves along the outer shape of the corrugated member 31, a large deformation of the inclined surface on the front side of the corrugated beam portion 41 cannot be obtained, and the inclined surface on the front side of the corrugated beam portion 41 is lowered as described above at the transfer position. This is because the behavior that rises is not obtained.

  For example, when the transported article is a white wart primary hybrid varieties called F1 which is the most cultivated variety for commercial purposes, the pepper has a cross-sectional diameter of 20 to 40 mm. If H is about twice the average height of pepper as 30 mm, it can be reliably supported.

  In the present embodiment, the belt-shaped member constituting the flexible elastically deformable corrugated beam portion 41 uses a polyester canvas coated with urethane coating, but is not limited to this, and is an endless belt body. When the portion provided with the 40 corrugated beam portions 41 is wound around the drive pulley 31, the flexibility that allows the deformation of the mountain-shaped slope as the hem width before and after the corrugated beam portion 41 changes in the conveying direction changes. For example, a plastic resin such as rubber or polyethylene can be used.

  Further, the corrugated beam portion 41 has a skirt width L in the basic shape described above that is not less than 2 times and not more than 4 times the height H, and not less than one-fourth of the circumference of the driven pulley 31 and not more than the circumference. That is, if the skirt width is too long with respect to the height of the corrugated beam portion 41 in the basic shape, when the corrugated beam portion 41 moves along the outer shape of the driven pulley 31, Since the direction is not greatly displaced with the skirt as a fulcrum, as described above, it is not possible to obtain a behavior in which the front slope of the corrugated beam portion 41 moves upward at the transfer position.

  Furthermore, even when the skirt width L of the corrugated beam portion 41 in the basic shape is too short or too long than the circumference of the driven pulley 31, the direction of the inclined surface on the front side of the corrugated beam portion 41 is greatly displaced with the skirt portion as a fulcrum. Therefore, as described above, it is not possible to obtain the behavior that the inclined surface on the front side of the corrugated beam portion 41 moves upward at the transfer position.

  On the other hand, in this embodiment, six rows of conveyor belt units 35 are arranged, and the corrugated beam portions 41 (solid portions in FIG. 1) in the odd-numbered conveyor belt units 35 are arranged in the same phase, and even rows are arranged. The corrugated beam portions 41 (filled portions in FIG. 1) of the conveyor belt unit 35 are arranged in the same phase, but are shifted from the odd-numbered row of corrugated beam portions 41 by a half phase. That is, in the top view of the transport conveyor line 36, the corrugated beam portions 41 on the adjacent transport belt units 35 are arranged in a staggered manner.

  In this way, in the conveyor line 36 configured with a plurality of conveyor belt units 35 arranged in parallel, the corrugated beam portions 41 are arranged in a staggered manner, so that the long article supplied from the article supply conveyor 10 to the article delivery position is provided. For example, the pepper 70 is supported and conveyed by the corrugated beam portion 41 as described below, and is discharged to the article discharge conveyor 50.

  The shift of the corrugated beam 41 is not limited to a half phase, and may be a phase of 1/3, 1/4, or may be shifted randomly in adjacent rows. It is only necessary that the front side and the back side in the conveyance direction of the long object can be alternately sandwiched by the plurality of corrugated bars 41.

  The peppers 70 are conveyed one by one toward the longitudinal direction of the first supply conveyor line 14, transferred to the second supply conveyor line 17, and supplied toward the article delivery position with the article conveyance conveyor 30.

In the article delivery position, when the corrugated beam 41 of the odd-numbered conveyor belt units 35 of the conveyor line 36 starts to rise upward toward the article delivery position, the corrugated beam of the even-numbered conveyor belt units 35 41 is present in front and rear in the conveying direction with a half phase shift with respect to the corrugated beam portions 41 of the odd-numbered conveying belt units 35. Paying attention to the corrugated beam 41 that is shifted forward in the half-phase conveying direction in the even-numbered conveying belt unit 35, above the corrugated beam 41 just before the article delivery position in all or part of the odd-numbered conveying belt unit 35. As the slope angle of the front-side slope of the corrugated bar 41 changes from θ ₁ to θ ₀ while the front-side slope of the corrugated beam portion 41 supports the bottom portion of the pepper 70 by the upward movement, the pepper 70 is pushed forward in the transport direction. As a result, the back side of the pepper 70 in the conveying direction is supported. At that time, since the corrugated beam 41 of the even-numbered transport belt unit 35 stands up on the front side of the pepper 70 in the transport direction, the front surface of the pepper 70 in the transport direction of the even-numbered transport belt unit 35 It contacts the rear surface of the corrugated bar 41 in the conveying direction. Accordingly, the pepper 70 is sandwiched between the corrugated beam 41 of the odd-numbered conveyance belt unit 35 and the corrugated beam 41 of the even-numbered conveyance belt unit 35 on the back side and the front side in the conveyance direction. The transport unit 30a can be transported stably without falling down on the upper side of the tilt.

  The pepper 70 conveyed through the article horizontal conveyance section 30b through the article inclination conveyance section 30a of the article conveyance conveyor 30 is located on the rear side in the conveyance direction of the corrugated beam section 41 of the even-number conveyance belt unit 35 at the conveyance end of the horizontal conveyance section 30b. Since the inclined surface is deformed so as to gradually fall down, the pepper 70 is transferred to and discharged from the discharge belt unit 53 of the discharge conveyor line 54 of the article discharge conveyor 50 without receiving an impact.

Other Embodiments In the above-described embodiment, one corrugated beam portion 41 as an article support means is provided on the outer peripheral surface of one endless belt main body 40 by one belt-like member. A corrugated bar 41 may be provided.

  In addition, although one endless belt body 40 is provided with a row of corrugated beam portions 41, for example, a wide endless belt having the width direction length of the six rows of conveyor belt units 35 shown in FIG. A plurality of rows of corrugated beam portions 41 provided at equal intervals may be provided. In this case as well, it is desirable to arrange the corrugated beam portions 41 in a staggered manner. In this case, it is desirable to provide a guide plate or the like for preventing the article from dropping on both sides of the wide endless belt. Of course, the article supply conveyor 10 may be configured similarly.

  In addition, the corrugated beam 41 forms a space between the belt-like member 40 by bending the belt-like member into a mountain shape, and moves the outer track of the driven pulley 31 from the basic shape moving along the straight conveyance path shape. By changing the skirt interval of the corrugated shape, the slope angle of the corrugated beam portion 41 is changed, and the front slope in the conveyance direction of the corrugated beam portion 41 is in a substantially horizontal posture, and is supplied at the delivery position of the transported article. However, the corrugated bar 41 need not be hollow, and may be a solid structure made of a flexible resin such as sponge. In short, it is only necessary that the slope angle of the corrugated beam portion 41 is changed by changing the skirt portion of the corrugated shape while moving the outer shape of the driven pulley 31 from the basic shape moving along the straight conveyance path shape.

  Of course, the convex shape of the corrugated beam portion 41 may be a polygonal shape such as a semicircular shape, a triangular shape, or the like, as viewed in the conveying direction (as viewed from the front of the article conveying conveyor 3). In short, the convex slope angle is changed by changing the convex skirt interval while moving the outer shape track of the driven pulley 31 from the basic shape moving along the straight conveyance path shape. However, the shape may be any shape that is substantially horizontal at the delivery position.

  On the other hand, the conveyance end portion of the second supply belt unit 17 of the article supply conveyor 10 and the conveyance start end portion of the conveyance belt unit 35 of the conveyance belt conveyor 30 are overlapped along the conveyance direction, so that the second at the delivery position of the conveyance article. Conveyed articles such as pepper on the supply belt unit 17 are delivered to the corrugated beam portion 41 of the conveyance belt unit 35. However, instead of the second supply belt unit 17, a transfer plate is provided in the gap between the conveyance belt units 35 arranged in parallel. May be arranged so that the transported article transferred from the first supply belt unit 13 to the transfer position is pushed and supplied onto the transfer plate with a pusher or the like toward the transfer position of the transfer article.

Further, in the first embodiment described above, the article inclined conveying unit 30a of the article conveying conveyor 30 is configured to convey the conveyed article obliquely upward, but is configured to convey the conveyed article obliquely downward. Also good . In this case, contrary to the first embodiment, as the corrugated beam portion 41 moves on the outer shape of the driven pulley 31, the inclined surface on the back side of the conveyance starts to be inclined, assumes a substantially horizontal posture at the transfer position, and lowers downward. Therefore, the conveyed article can be delivered to the article supply conveyor 10 without impact.

  On the other hand, the article supply conveyor 10, the article transport conveyor 30, and the article discharge conveyor 50 are not only constituted by endless belts, but are provided with endless chains on both sides in the width direction of the article transport path, and are plate members passed between the opposing chains. A plurality of slat conveyors may be provided at regular intervals along the conveying direction, and for example, the corrugated beam portion may be provided on each plate member.
