Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyed product aligning device in a flat belt conveyor for accurately aligning the posture of a conveyed product such as a grain bag in the process of being conveyed.

[0002]

[Prior art]

 2. Description of the Related Art In a conveying process using a flat belt conveyor, a conveyed product aligning device that corrects a conveyed posture of conveyed products by guides acting on both sides of the conveyed products is known.

[0003]

[Problems to be solved by the device]

 In the prior art as described above, when aligning relatively large weighted products having a high friction coefficient, such as grain bags, the guiding action of the guide body makes it possible to align the posture accurately in a short transportation distance. Is difficult. The present invention solves the above-mentioned drawbacks of the prior art and attempts to accurately align the conveyed objects with a short conveying distance.

[0004]

[Means for Solving the Problems]

 Carrying posture by acting from both sides of the transported object 4 on both sides of the transport path of the flat belt conveyor that transports the transported transported object 4 on the flat belt 3 driven and rotated by the driving roll 1 and the guide rolls 2 and 2. Guides 5 and 5 for correcting the above, and guides for guiding only the central portion of the flat belt 3 to the back side of the flat belt 3 at a position corresponding to the arrangement of the guides 5 and 5 slightly above the other conveying surface. It is configured as an apparatus for aligning conveyed objects on a flat belt conveyor provided with 6.

[0005]

[Operation and effect of the device]

 In the course of the conveyance, the conveyance object 4 mounted on the flat belt 3 is aligned by correcting the conveyance posture and left and right positions by the guide bodies 5 and 5 provided on both sides of the conveyance path. A guide body 6 is provided on the rear surface side of the flat belt 3 at the corresponding position to guide only the right and left central portions of the flat belt 3 slightly above the other conveying surfaces. Thus, since the objects 4 are aligned while being supported in a small area, the conveyed objects 4 can be accurately aligned in a short conveying distance.

【Example】

 The flat belt conveyor has conveyor frames 8 and 8 which are supported in an inclined shape and supported by left and right columns 7 and 7, a driving roll 1 and a plurality of guide rolls 2 which are mounted on the conveyor frames 8 and 8. , 2 and a flat belt 3 wound around them. 9 is a shaping roll, which acts on the upper surface of the grain bag 4 which is a conveyed object on the flat belt 3 to perform shaping, and has a width substantially the same as that of the flat belt 3 and a large diameter in the central portion. Both sides are formed in a drum shape with a small diameter, and the peripheral working surface is made of elastic material.

Reference numerals 10 and 10 denote rocking frames, the lower ends of which are pivotally supported by shafts 11 which are erected on the conveyor frames 8 and 8, and the shaping roll 9 described above is mounted on the shaft 12 at the upper part. One side of the rocking frame 10 is also used as a transmission case, and a chain 15 is wound between a sprocket 13 attached to the shaft 11 and a sprocket 14 provided on the upper part of the rocking frame 10, and further. A gear 16 coaxially mounted on the sprocket 14 and a gear 17 at the end of the shaping roll shaft 12 are meshed with each other so that the shaping roll 9 can be driven and rotated in the arrow A direction.

Reference numeral 18 denotes a rocking support rod, the upper end of which is attached to a pin 19 which is rotatably held on the side surface of the rocking frame 10, and the middle thereof is rotatably mounted on the side surface of the conveyor frame 8. It is slidably inserted into a through hole (not shown) opened orthogonally to the axis of the shaft 20 to be held. Reference numeral 21 denotes a pin, which is inserted and fixed at an appropriate position of the rocking support rod 18, and the sliding range of the rocking support rod 18 is restricted by the contact between the pin 21 and the shaft 20. The descending position of 9 is regulated. Further, a compression spring 22 is provided on the side of the swing support rod 18 protruding from the shaft 20, and a nut 23 is screwed on the tip of the swing support rod 18 so that the spring force can be adjusted.

As with the shaping roll 9, the guide roll 2 of the flat belt 3 positioned corresponding to the shaping roll 9 is also formed in a drum shape with a large diameter at the center and small diameters at both ends. Reference numeral 24 denotes an electric motor, which drives and rotates the drive roll 1 by the belt 25, and drives the shaft 11 from the drive roll 1 through the chain 26. On both sides of the conveying path on the front side of the shaping roll 9, the first guide bodies 5 and 5 are provided upright at an interval w substantially the same as the width of the grain bag 4 to be conveyed. Second guide bodies 28, 28 are erected on both sides with a space W slightly wider than the space w between the first guide bodies 5, 5. The first guide bodies 5, 5 and the second guide bodies 28, 28 are continuously and integrally provided by a plate body, and are attached to a mounting plate 27 fixed to the conveyor frames 8, 8.

The guide roll 2 that guides the back surface of the flat belt 3 at the positions corresponding to the first guide bodies 5 and 5 is formed such that the center portion of the left and right sides has a large diameter with a constant width, and the flat belt 3 that guides the other flat surface. It is configured as a guide body 6 that guides the upper part of the room. The rotation of the electric motor 24 is transmitted to the drive roll 1 via the belt 25, and the flat belt 3 wound around the drive roll 1 and the guide rolls 2 and 2 is rotated in the arrow B direction. The shaft 11 is driven from the drive roll 1 via the chain 26, then the sprocket 13 attached to the shaft 11 drives the sprocket 14 by the chain 15, and the gear 16 is coaxially mounted on the sprocket 14. The shaping roll 9 is driven and rotated in the direction of arrow a by the engagement of the gear 17 at the end of the shaping roll shaft 12.

The rounded grain bag 4 loaded with the grain is loaded on a flat belt conveyor and is transported. In the transporting process, the grain bag 4 is first aligned by the first guide bodies 5, 5. A guide body 6 is provided on the rear surface side of the flat belt 3 at a position corresponding to the arrangement of the guide bodies 5 and 5 but which guides only the center position of the flat belt 3 in the left-right direction to a position slightly higher than the other conveying surfaces. Since the grain bag 4 being conveyed is supported by the flat belt 3 surface on the guide body 6 in a small area, the conveyance posture of the grain bag 4 and its left and right positions can be accurately corrected with a short conveyance distance. Are aligned and conveyed to the lower side of the shaping roll 9.

The grain bag 4 conveyed below the shaping roll 9 is elastically urged downward and has a drum-shaped shaping roll 9 having a large diameter in the center and small diameters on both sides. By the rotation in the promoting direction, the filling in the grain bags 4 is sequentially pushed from the center to both sides for shaping, and the shaping action makes the grain bags 4 into a flat shape suitable for stacking. It Due to this shaping action, the grain bag 4 is shaped from a rounded shape to a flat shape, so that the width of the grain bag 4 is slightly widened. 1 Since it is erected at a distance W slightly wider than the guide bodies 5 and 5, it does not hinder the shaping operation and guides both sides of the widened grain bag 4 after shaping. Transported without disturbing the posture. The same effect can be obtained even if a plurality of guide bodies 6 are provided or if they are provided continuously in the transport direction.
