Description

  The present invention relates to a transport device that transports a bag filled with grains and the like, and more particularly to a configuration of a transport device that can be easily carried out to the next step provided at a transport path terminal portion.

A roller conveyor is provided to convey the grain bag between the bagging machine that weighs the grain while it is put into the grain bag and the lift device that raises the packed grain bag to a predetermined height. A carry-out device that smoothly conveys the granule bag is disclosed in Patent Document 1.
Conventionally, flat belt conveyors wrapped with flat belts increase the frictional resistance of the flat belt's bag mounting surface so that the bag can be conveyed without slipping and the frictional resistance of the backside of the flat belt guided by the rollers can be reduced. It is well known that the roller is configured to be small and rotate lightly.
JP 2001-151480 A

The carry-out device described in Patent Document 1 is a roller conveyor in which a large number of rollers are arranged side by side, and since the packed bag is directly conveyed on the roller, the grain bag is deformed between the rollers. It was not enough to move the grain bag with light force. Further, if some or all of the rollers are forcibly driven, there is a problem that the conveyor becomes complicated and expensive. Furthermore, in order to convey the grain bag on the conveyor in an upright and stable state, it is better to convey the grain bag with the longitudinal direction of the grain bag in the conveying direction, but the grain bag is made to stand upright at the end of the conveyance path. After horizontally sliding and rotating, it must be tilted onto the lift table of the next process, and a large force is required to horizontally rotate the grain bag that has been deformed and dropped between the rollers. It was what I needed. Further, when the grain bag is sent out at a high speed, a force for stopping the grain bag with a large inertial force at the end of the conveyance path is also required.
Therefore, the present invention can easily transport a heavy bag such as a grain bag with a light force, and suppresses the inertial force of the bag sent out at high speed on the conveyor at the time of conveyance at the end of the conveyance path. It is an object of the present invention to provide a transport device such as a grain bag that can efficiently carry out the work to the next process.

  Concatenated to the end of the transport path A of the bag 1 filled with grains and the like, provided with a flat belt conveyor 2 having the same transport direction B, and provided with a plurality of rollers 4, 4 for rolling and guiding the flat belt 3, The bag conveying device is configured to constitute a braking conveyor 2 in which the frictional resistance on the back side of the flat belt 3 guided by the rollers 4 and 4 is larger than the frictional resistance on the surface of the flat belt 3 on which the bag 1 is mounted.

  A bag conveying device comprising rollers 4 for rolling and guiding the flat belt 3 at rough intervals, and a bag 1 on which the mounted bag 1 is bent together with the flat belt 3 to bend downward between the rollers 4 and 4; To do.

  The invention according to claim 1 is provided with a flat belt conveyor 2 connected to the end of the conveying path A of the bag 1 filled with grains or the like and having the same conveying direction B, and rollers 4 for rolling and guiding the flat belt 3. 4 is provided, and a braking conveyor 2 is constructed in which the friction resistance on the back side of the flat belt 3 guided by the rollers 4 and 4 is larger than the friction resistance of the flat belt 3 on the bag 1 mounting surface. Therefore, even if the bag 1 filled with grains or the like is sent toward the conveyance end at a high speed, the frictional resistance on the back side of the flat belt 3 guided by the rollers 4 and 4 of the braking conveyor 2 connected to the conveyance path A end. Is large, the inertial force of the bag 1 can be appropriately braked and the bag 1 can be reliably stopped on the brake conveyor 2. Further, since the friction resistance on the bag 1 mounting surface side of the conveyor 2 is small, the friction resistance between the mounting surface of the flat belt 3 and the bag 1 is small, and the bag 1 is moved while being slid on the mounting surface or horizontally. It is easy to rotate.

  According to the second aspect of the present invention, the rollers 4 and 4 for rolling and guiding the flat belt 3 are arranged at rough intervals, and the loaded bag 1 is bent downward together with the flat belt 3 between the rollers 4 and 4. Even if the bag 1 filled with grains or the like is directed to the end of conveyance and sent out at a higher speed, the roller 4 between the rollers 4 and 4 arranged at the rough interval of the brake conveyor 2 connected to the end of the conveyance path A The bag 1 is bent to become resistance, and the inertial force of the bag 1 is moderately suppressed by braking, so that the bag 1 can be reliably stopped on the brake conveyor 2.

The present invention will be described by taking, as an example, the transportation of a grain bag after weighing bagging in a vertical grain sorting and weighing machine and the operation using a moving lifter at the time of unloading. A vertical grain sorting and weighing machine 10 shown in FIG. 1 is a conventionally known one, supplying brown rice after mashing from a hopper 11, and scraping rice from surrounding sorting nets while pulverizing with an internal mashing spiral. The cereal is leaked, and only the sized particles are fed to the upper tank 12 and supplied to the grain bag 1 on the weighing table 13. In addition, when the filling amount reaches a predetermined weight, the shutter 15 is closed, and the sized grains to be cerealed are stored in the tank 12 and the grain bag 1 is taken out from the weighing table 13 during that time.
A bag catch 16 and a conveyor 18 that stand the grain bag 1 and open the bag mouth 19 are placed on the weighing platform 13, and the bag catch 16 holds the bag mouth 19 of the grain bag 1. The sized particles supplied from the shutter 15 can be easily filled, and the grain bag 1 can be moved laterally by a conveyor 18 with a light force.
As shown in FIG. 2B, the conveyor 18 has a specific configuration in which a plurality of rotatable cylindrical rollers 4 and 4 are arranged side by side and are pivoted between a pair of side frames 9 and 9. The tension of the flat belt 17 can be adjusted by winding an endless flat belt 17 around the rollers 4a and 4a at the left and right ends of the roller 4 and moving and adjusting one of the rollers 4a and 4a horizontally. it can. The friction resistance of the flat belt 17 guided by the rollers 4 and 4 of the flat belt 17 is smaller than the friction resistance of the surface of the grain bag 1 and is usually 30 kg. Depending on the region, the grain bag 1 has a weight of 60 kg. Is a conventionally well-known conveyor configuration that allows the rollers 4a and 4a at both ends to rotate lightly even when placed.
In addition, about the grain bag 1 mounting surface of the flat belt 17, although it forms in a cross-sectional saw blade shape and the frictional resistance with the grain bag 1 is enlarged, it is also possible by making uneven surface and the surface rough. The grain bag 1 can be conveyed without slipping on the flat belt 17.

When the filling amount of the grain bag 1 reaches the predetermined weight on the weighing platform 13, the shutter 15 is closed, the bag mouth 19 of the grain bag 1 is removed from the bag catch 16, and the grain bag 1 is moved laterally on the conveyor 18. Let On the grain bag 1 conveying side, a conveyor 5 connected to the conveyor 18 and having substantially the same width and height as the conveyor 18 is disposed. The conveyor 5 has the same configuration as that of the conveyor 18, and a flat belt 6 is wound around a plurality of rotatable cylindrical rollers 4 and 4 arranged side by side. The flat belt 6 is guided by the rollers 4 and 4. It is the conventionally well-known conveyor 5 which made the friction resistance of the grain bag 1 mounting surface larger than the friction resistance of the flat belt 6 to be done.
The grain bag 1 moved from the conveyor 18 to the conveyor 5 is conveyed in an upright state toward the end of the conveyance path A after closing the bag mouth 19 on the conveyor 5.
In addition, the conveyance distance of the conveyor 5 can be set arbitrarily, and the conveyor 5 of a predetermined length may be connected. Also, as shown in FIG. You may form in a downward slope toward it.

A conveyor 2 having a short overall length is connected to the end of the conveyance path A of the conveyor 5. The configuration of the conveyor 2 is basically the same as that of the conveyors 5 and 18, but the configuration of the flat belt 3 is different. The flat belt 3 of the conveyor 2 has a friction resistance on the back side of the flat belt 3 guided by the rollers 4 and 4 larger than that of the grain bag 1 mounting surface. , And the reverse side frictional resistance guided by the rollers 4 and 4. In the flat belt conveyor, when the frictional resistance on the back surface side guided by the rollers 4 and 4 is increased, slippage between the outer ends of the rollers 4a and 4a, which are bent portions of the flat belt 3, is eliminated, and the rotation resistance of the rollers 4a and 4a Becomes larger. Moreover, if the frictional resistance of the flat belt 3 on the grain bag 1 mounting surface is reduced, the grain bag 1 can be easily slid on the flat belt 3.
The flat belt 3 can also be configured as a conveyor 2 by turning upside down and winding a belt manufactured by the same manufacturing method of the same material as the flat belts 6 and 17 that have been generally used. A conveyor 2 can be provided.
As shown in (a) of FIG. 3, when the grain bag 1 is slowly conveyed, the grain bag 1 stops early due to the rotational resistance of the conveyor 2. There is little frictional resistance of the grain bag 1 mounting surface, and the grain bag 1 can be easily moved on the conveyor 2.
Further, as shown in FIG. 3B, when the grain bag 1 is conveyed at a high speed, the inertial force in the conveying direction of the grain bag 1 is increased. Is suppressed, the grain bag 1 is not conveyed excessively, and does not fall off the conveyor 2.

FIG. 4 shows a working example of the present invention, which is a working mode for transporting and carrying out the grain bag 1 filled with the sized particles by the vertical grain sorter 10. The transport direction B can be changed in any direction with respect to the vertical grain sorter 10.
First, the grain bag 1 filled with a predetermined amount of sized particles on the weighing platform 13 is closed to the conveyor 5 at the position where the grain bag 1 is moved to the conveyor 5 and then conveyed toward the conveyor 2 connected to the end of the conveyance path A. To do. This conveyance raises the grain bag 1 and conveys it to the conveyor 2 so that the conveyance direction B becomes the longitudinal direction of the grain bag 1.
The grain bag 1 on the conveyor 2 carries out the moving work by bringing the movable lifter 20 close to the conveyor 2. The grain bag 1 to be stood and transported moves to the conveyor 2 by the inertial force in the transport direction B, arbitrarily slides and horizontally rotates the grain bag 1 according to the unloading direction of the next process, The movable lifter 20 is lowered onto the lifting table 21. Thereafter, it can be transported to another place such as a truck by the movable lifter 20.
FIG. 5 shows another example of work for moving the movable lifter 20 closer to the conveyor 2. FIG. 5C shows that the right side surface of the movable lifter 20 is moved closer to the conveying extension direction of the conveyor 2. The grain bag 1 is rotated about 90 degrees in the horizontal direction while standing on the conveyor 2, moved to the carry-out end on the conveyor 2, and then dropped onto the lifting table 21 of the movable lifter 20 and carried out. . On the other hand (d), the front side of the movable lifter 20 is moved closer to the conveying extension direction of the conveyor 2, and the grain bag 1 is moved on the conveyor 2 while standing. At the time of this movement, the conveyor 2 that can rotate in the conveying direction B rotates or slides on the flat belt 3 of the conveyor 2 having a small frictional resistance on the mounting surface, and the fork 22 of the movable lifter 20 is moved. Slide on the top. In these work modes, since there is no operation of bending the waist and lifting heavy objects, the grain bag 1 can be efficiently and easily carried out.

FIG. 6 shows an embodiment in which the conveyor 5 is formed so as to be inclined downward in the transport direction B, and a stationary lifter 23 is arranged in the next process of the conveyor 2.
The present invention is not limited to the conveyance of the grain bag 1 but can be used in a work mode in which the direction of the bag 1 is changed at the end of the conveyance path A in the conveyance of the bag 1 such as vegetables, fertilizer, and earth and sand.
