Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag shaping device for a flat belt conveyor that shapes a grain bag during the transportation process when the grain bag is transported to a palletizer or the like.

[0002]

[Prior art]

 Conventionally, as a bag forming apparatus for this flat belt conveyor, there is one that uses a shaping roll that rotates in contact with the upper surface of the grain bag during conveyance.

[0003]

[Problems to be solved by the device]

 When the grains are put into a paper grain bag all at once, it is difficult to stack the grains because the grains are not evenly filled in every corner of the bag and the center bulges out. It is necessary to shape the grain bag into a flat shape. However, sufficient rotation cannot be achieved simply by rotating the shaping roll in contact with the upper surface of the grain bag, and when an extremely strong contact force is applied, the surface of the paper bag is wrinkled and unattractive. The present invention solves the above-mentioned drawbacks of the prior art, and aims to provide a bag shaping device for a flat belt conveyor that can reliably shape a paper grain bag that is difficult to shape.

[0004]

[Means for Solving the Problems]

 In a flat belt conveyor in which a grain bag 4 or the like is mounted on a flat belt 3 which is driven and rotated by a driving roll 1 and guide rolls 2 and 2, the central portion has a large diameter and both ends are in the conveying path. Is a drum-shaped shaping roll 5 having a small diameter, which is elastically contacted with the upper surface of the grain bag 4 and is rotatably mounted so as to be rotatably driven in a direction for urging the conveyance. The corresponding guide rolls are similarly formed into a drum-shaped shaping guide roll 6 having a large diameter at the central portion and small diameters at both ends, thereby forming a grain bag shaping device for a flat belt conveyor.

[0005]

[Operation and effect of the device]

 During transportation, the grain bag 4 mounted on the flat belt 3 elastically abuts on the upper surface of the grain bag 4 and is driven and rotated in a direction for urging the conveyance, and the center has a large diameter and both ends. Is a drum-shaped shaping roll 5 having a small diameter and a drum-shaped shaping guide roll 6 having a large center and guiding both sides of the flat belt 3 at the position corresponding to the shaping roll 5 and having small diameters at both ends. The bulging part in the center of the grain bag 4 is pressed from both the upper and lower sides to move the grains to the left and right sides of the grain bag 4 in sequence to fill the grains in every corner of the grain bag 4, and the upper and lower sides are flat. It can be reliably shaped into a shape.

【Example】

 The example in the figure shows a palletizer, which is a device for stacking grain bags on a pallet in multiple stages, and the device of the present invention was implemented on a flat belt conveyor for supplying the grain bags. The flat belt conveyor (A) includes conveyor frames 8 and 8 which are supported at their terminal ends by columns 7 and 7 and are formed in an inclined shape, a drive roll 1 mounted on the conveyor frames 8 and 8 and a plurality of guides. It is composed of rolls 2 and 2 and a flat belt 3 wound around them. At the end of the flat belt conveyor (A), there is a waiting conveyor (B) that receives the supply of the grain bag 4 from the flat belt conveyor (A) and stops it at a predetermined position, that is, the gripping position of the palletizer. It is provided.

The shaping roll 5 acts on the upper surface of the grain bag 4 being conveyed on the flat belt 3 and directly corrects the deformation of the grain bag 4. The part has a large diameter and both ends are formed into a small drum shape, and the surrounding working surface is made of elastic material. Numerals 9 and 9 are swinging arms, the lower end of which is rotatably supported on both outer sides of the conveyor frames 8 and 8 of a rotary shaft 10 which is erected between the conveyor frames 8 and 8, and the upper end of which is provided with A shaping roll 5 is mounted on a shaft 11. One side of the swing arm 9 is also used as a transmission case, and a chain 14 is hung between a sprocket 12 attached to the rotary shaft 10 and a sprocket 13 mounted on the upper part of the swing arm 9. Further, the gear 15 coaxially mounted on the sprocket 13 and the gear 16 at the end of the shaping roll shaft 11 are meshed with each other, and the shaping roll 5 is driven and rotated in the arrow (a) direction.

Reference numeral 17 denotes a swing support rod, the upper end of which is attached to a pin 18 which is rotatably held on the side surface of the swing arm 9, and the middle of which is rotatable on the side surface of the conveyor frame 8. The shaft 19 is slidably pushed through a through hole (not shown) formed perpendicularly to the axis of the shaft 19 held by the shaft. Reference numeral 20 denotes a pin, which is inserted into an appropriate position of the rocking support rod 17, and the abutment between the pin 20 and the shaft 19 restricts the rocking range of the rocking support rod 17, whereby the shaping roll 5 The descending position of is regulated. Further, a compression spring 21 is provided on the side of the swing support rod 17 protruding from the shaft 19, and a nut 22 is screwed on the tip of the swing support rod 17 so that the spring force can be adjusted. Reference numerals 23 and 23 denote guide plates, which are erected at the positions corresponding to the shaping rolls 5 of the conveyor frames 8 and 8 to correct the conveyance posture of the grain bag 4.

The shaping guide roll 6 is located slightly on the upstream side of the shaping roll 5 in the conveying direction and guides the back surface of the flat belt 3. As with the shaping roll 5, the center has a large diameter and both ends have a small diameter. It is shaped like a drum. Reference numeral 24 denotes an electric motor, which is configured to be able to drive the drive roll 1 of the flat belt conveyor (A) and the drive roll 28 of the standby conveyor (B) by the belt transmission mechanisms 25 and 26.

The standby conveyer (B) is provided at the end of the flat belt conveyer (A), and a narrow belt 30 is wound between a large number of rolls 29, 29 and the drive roll 28 to form a grain bag. 4 is configured to be conveyable, and between the rolls 29, 29 on both the left and right sides of the narrow belt 30 is formed as an insertion space for a gripping claw (not shown) of the palletizer. Reference numeral 31 is a stop plate, which is erected at the end of the standby conveyor (B) and provided with a limit switch 32 projecting forward from an opening in the center thereof. By contacting the motors 4, the electric power to the electric motor 24 is cut off and the conveyors (A) and (B) can be stopped.

Reference numeral 33 denotes a chain transmission, which is configured to transmit the power of the drive roll 1 to the rotary shaft 10. During transportation, the grain bag 4 mounted on the flat belt 3 has its transporting posture corrected by the guide plates 23, 23 on both sides, and then the shaping guide roll 6 performs shaping guidance from the back side of the flat belt 3. To do. Since the shaping guide roll 6 is formed in a drum shape with a large central part and small ends at both ends, the grain bag 4 being conveyed is lifted up at its central part to fill the filled grain on both left and right sides. And it is made to flow in the up-and-down direction and evenly filled in every corner of the grain bag.

Further, the shaping roll 5 is brought into contact with the upper surface of the grain bag 4 by an appropriate elastic force of the compression spring 21, and the central portion of the grain bag 4 is formed by the large diameter portion at the center of the shaping roll 5. The pressed and filled grains are flowed to the left and right sides and up and down to fill every corner of the grain bag 4, and the upper and lower sides are shaped flat. Further, the shaping roll 5 has a peripheral action surface made of an elastic material, and a rocking arm which is elastically urged downward about a rotary shaft 10 by a compression spring 21 interposed in the rocking support rod 17. It is supported by 9, 9 and performs proper shaping without damaging the bag due to proper elastic action. If the center portion of the shaping guide roll 6 has a large diameter and both ends have a small diameter, the same effect can be obtained even if the gap is not continuous and has a step.
