Description

  The present invention relates to a filling device for a container that transports bulk products such as agricultural products and industrial products and stores them in a container.

  It is carried out to improve the handleability by transporting bulk products such as harvested agricultural products and industrial products on a conveyor line and storing them in a container in a predetermined amount. By putting it in a container, it is possible to store it safely and move a large amount of roses at a time. This is used in the field of transportation of many articles, and as one of them, various techniques for accommodating in a container so as not to damage the object to be conveyed have been proposed.

  For example, as an example of a crop harvesting machine, Japanese Utility Model Publication No. 3-48420 discloses a potato harvester in which a storage tank is arranged in a machine frame below the end of a feed conveyor that conveys harvested potatoes, on both sides of the storage tank. A discharge conveyor is installed, and a discharge conveyor that can travel in either direction is installed between the two discharge ports at the bottom of the storage tank. The left and right container stages are placed on the wooden frame under the two discharge ports via a hydraulic device. A potato harvester is shown that is tiltably mounted and has a potato storage container mounted on its container stage.

  In this potato harvester, the potato was transferred from the storage tank on the harvester to the shipping container in the past. Damage is prevented, unloading work time is greatly reduced, and work efficiency is improved.

  In addition, as an example of an installation type crop transportation storage device, Japanese Patent No. 3408497 discloses a transport conveyor for transporting crops in a predetermined direction, and is arranged below the delivery side end of the transport conveyor so as to cross the predetermined direction. And a delivery conveyor capable of delivering crops from each of both delivery side ends by forward and reverse rotation, and a container placement portion disposed below each of the delivery side ends of the delivery conveyor. An agricultural product transport and storage device, wherein the delivery conveyor slides the delivery conveyor in the delivery direction, thereby changing the delivery position of the crop into the container, and the upper surface of the crop accumulated in the container. A slide mechanism for flattening the container mounting portion is provided, and each container mounting portion can be lowered as the amount of farm products accumulated in the container increases. A lifting mechanism is provided, and at the delivery side end of the delivery conveyor, there is a crop detection unit that detects the distance to the crop in the container below it, and the lifting mechanism has a distance to the crop within the set value. If it becomes, the conveyance storage apparatus for agricultural products controlled so that a container mounting part may be lowered | hung is shown.

  In this agricultural work transport and storage device, the drop height of the crop can be lowered according to the accumulation state of the crop by the slide mechanism of the delivery conveyor and the lifting mechanism of the container, and the horizontal delivery position can be changed by the slide mechanism of the delivery conveyor Thus, the upper surface of the crop accumulated in the container can be made substantially flat. Therefore, it is said that crops are piled up in a mountain shape in the container and the crops are not damaged by the collapse, and the internal capacity of the container can be used effectively.

  In addition, since the delivery conveyor can deliver the crop from each of the two delivery side ends, if a predetermined amount of the crop is accumulated in the container placed on one of the container placement parts, the crop is accumulated. The container can be exchanged for an empty container, and during the container replacement work, the work for storing the crop from the delivery conveyor can be stored in the container mounted on the other container mounting section. The work can be done very efficiently.

  However, the apparatus as shown in the above-mentioned conventional document has a configuration in which a delivery conveyor as a conveying means protrudes on the container, which is bothersome and troublesome when lifting the container for replacement. If the vertical distance between the delivery conveyor and the container is increased, the drop into the container will increase.

  In addition, in the conventional apparatus configuration, if the conveying means is not positioned on the container to be exchanged, there is a problem that the tilt angle of the container is restricted or containers having different sizes cannot be used. For example, the conveying means as shown in Patent Document 2 is composed of a single belt conveyor that slides to the left and right, and even if the distance between two containers is increased by design, the container is tilted when a container larger than a certain value is used. The end of the transport means does not reach the inner part of the container, and the distance that the loaded transport object rolls on the inner wall of the container becomes long, and the transport object is damaged. Further, when the distance between the two containers is increased in design, the apparatus is also increased in size.

  Even if the container on the filling side is inclined about 45 °, the conveying means is plunged long by using the diagonal length of the container, and the conveying means is not projected on the other container, When used, the entry distance of the transport means is reduced, and the other end protrudes greatly on the other container. In the case of crops, if the tilt angle of the container is small in the initial stage of filling and the slope of the throwing surface is steep, the speed of rolling inside the container increases, resulting in damage and corruption. In the initial stage of filling, it is desirable to inject the container so that it is placed with a small drop by tilting the container near 90 ° to loosen the slope of the throwing surface.

  In view of this, the present invention includes a horizontally long conveying means having conveying end portions at both left and right ends and capable of switching the conveying direction. The container mounting table is provided with a container mounting table on which containers are respectively placed below both transport ends, and the container mounting table is provided with a tilting mechanism that shortens the falling distance from the transport end into the container. After filling the container, the filling device that changes the transport direction to the other container and fills the container is easy to replace the container, the container tilt angle is not regulated, and containers of various sizes are used An object of the present invention is to provide a filling device for a compact container which is possible and does not damage the object to be conveyed.

The proximity sensors 47a and 47b are sensors that detect the same metal as the proximity sensors 46a and 46b. When the lower conveying conveyor 20 slides and its conveying ends 20a and 20b are located near the upper sides of the opposing surfaces of the two containers 7L and 7R, the full detection piece 27 is detected by the proximity sensors 47a and 47b. Keep it.

  Container detection sensors 28a and 28b and filling detection sensors 29a and 29b are provided in the vicinity of both longitudinal ends of the conveyor frame 22a of the lower conveyor 20 respectively. The container detection sensors 28a and 28b are optical sensors, and are fixed to the conveyor frame 22a in a state where the sensor portion is directed obliquely downward in the sliding direction of the lower transport conveyor 20, and the wall surface with the end of the lower transport conveyor 20 at the slide destination.

  In addition, a pair of slope plates 31 inclined obliquely outward and downward are provided on both conveying end portions 20 a and 20 b of the lower conveying conveyor 20 in the same manner as the upper conveying conveyor 10.

  As described above, the upper conveying conveyor 10 and the lower conveying conveyor 20 constitute the conveying means 5, and the driving roller 40, the idle roller 41, and the lateral regulating roller 45 laterally project the lower conveying conveyor 20 from the upper conveying conveyor 10. By sliding to the bottom, the extension mechanism of the transport means 5 is configured based on the length of the lower transport conveyor 20 in the transport direction.

  The container mounting table 50 has a rectangular plate-like bottom surface portion 50a and a rectangular frame-shaped side surface portion 50b substantially perpendicular to the bottom surface portion 50a in a substantially L shape so that the rectangular parallelepiped containers 7L and 7R can be placed thereon. Configure. And this container mounting base 50 is arrange | positioned so that the side part 50b may be opposed below each of both conveyance edge part 20a, 20b of the lower conveyance conveyor 20. FIG. At this time, the upper end of the side surface portion 50b and the upper ends of the containers 7L and 7R are set to have substantially the same height and are located slightly below the lower transport conveyor 20.

  In addition, the containers 7L and 7R shown in FIG. 1 of the present embodiment are outer containers of about 1700 mm in width, about 1100 mm in depth, about 1410 mm in height, and about 1600 mm in width, about 1000 mm in depth, about 1000 mm in depth, and about 1300 mm in height. A steel net is stretched between the side rails, which is common for agricultural products. The containers 7L and 7R are placed so that the opposing surfaces are in contact with the respective side surface portions 50b so as to be in the same position in the depth direction of FIG. In this embodiment, the distance between the containers 7L and 7R is about 2400 mm.

  The vertical member of the side surface portion 50b of the container mounting table 50 is provided with a plurality of height adjustment holes 50c in the vertical direction, and the bottom surface portion 50a is fastened and fixed by bolts and nuts through the height adjustment holes 50c. The mounting height of the bottom surface portion 50b can be adjusted by changing the position of the height adjustment hole 50c. For example, when using containers with half the height of the containers 7L and 7R, the mounting position of the bottom surface portion 50a is adjusted so that the upper end of the side surface portion 50b and the upper end of the container are substantially the same height. Put.

  The vicinity of the upper end of the vertical member of the side surface portion 50b is pivotally attached to the machine frame 3 around the horizontal left and right direction shown in FIG. Then, a pair of cylinders 52a and 52b are provided from the approximate center between both side surface portions 50b toward both side surface portions 50b. The cylinders 52a and 52b are hydraulic cylinders, the base is fixed to the machine frame 3, the rod tip is fixed to the side surface 50b, and the container mounting table 50 is pivoted about the rotation center 51 by the expansion and contraction of the rod. Try to rotate. A hydraulic unit 53 having a pump for generating hydraulic pressure and a control valve is provided in the machine frame 3 in the vicinity of the bases of both cylinders 52a and 52b, and the bottom surface 50a of the container mounting table 50 is parallel to the ground in response to a command from the control panel. And the most lowered position rotated by 85 ° so that the side surface portion 50b is in a substantially horizontal state. Further, the cylinders 52a and 52b are provided with a switch for detecting an extended end and a contracted end so as to have the above-mentioned operating angle, and are controlled by a control panel.

  Next, an example of the operation and control method of the container filling device 1 according to the present invention will be described. The left and right in the description are the left and right in FIG.

  The containers 7L and 7R are placed in a state where both the container placing tables 50 are in the lowest position, and the operation is performed by operating the control panel. While the right container mounting table 50 is stopped at the lowest position, the cylinder 52a is extended, the left container mounting table 50 is rotated to the highest position and stopped, and the lower conveyor 20 is slid to the left. And rush into the container 7L.

  And if the container detection sensor 28a provided in the vicinity of the left end of the lower conveyance conveyor 20 approaches and detects the inner surface of the container 7L, the slide is stopped. Even when the inner wall of the container 7L is not detected, the limit detection piece 26b provided on the lower conveyor 20 stops the position on the proximity sensor 46a as the slide limit. The lower transfer conveyor 20 that can slide about 1600 mm to the left and right is in a state in which the transfer end 20a has sufficiently reached the vicinity of the lower corner 7a in the container 7L having an inclined height of about 1300 mm.

  Next, the upper conveyor 10 and the lower conveyor 20 are driven and rotated so that the upper surfaces of the belts 11 and 21 rotate to the left. From the end of the supply conveyor C that transports the crops from outside the machine, the crops are put into an enclosure formed by the conveyor frames 12 a and 12 b and the gate plate 16 at the substantially center of the upper transport conveyor 10. By introducing the crops into the enclosure, it is prevented from overflowing out of the conveyor, and when the belt 11 turns, a predetermined amount of crops flows under the gate plate 16.

  The input crop is transported on the transport conveyor 10, slides down the slope plate 17 from the transport end 10 a, is transferred onto the belt 21 of the lower transport conveyor 20, and is transported to the left transport end 20 a by the lower transport conveyor 20. Then, it slides down the slope plate 31 from the transport end 20a and is put into the container 7L. At the time of delivery between the conveyors and loading into the container 7L, the slope plates 17, 31 prevent the pulleys of the transport end portions 10a, 20a from dropping and being damaged.

  Since the container 7L is inclined so that the surface on the side surface portion 50b side of the container mounting table 50 is inclined outward by 5 °, that is, substantially horizontal, the input crops roll in the container 7L at a high speed. Instead, it accumulates from the lower corner 7a with a small drop. Therefore, the outer periphery of the input crop is not damaged.

  And if the upper surface of the crop which the filling detection sensor 29a of the conveyance end part 20a of the lower conveyance conveyor 20 accumulate | stored continuously is detected for about 2 second, the rod of the cylinder 52a will be slightly contracted and the container mounting base 50 will be lowered | hung. Then, the filling detection sensor 29a does not detect the distance from the upper surface of the crop, and the lower transport conveyor 20 continuously accumulates the crop in the conveyor 7L. Since the input positions of the agricultural products from the lower conveyor 20 are concentrated, a mountain is formed in the container 7L. Subsequent crops are continuously put on top of the mountain, so the mountain grows as it collapses around. If it is a distorted sphere shape such as potato, it will not collapse smoothly and it will take time to collapse, so the filling detection sensors 29a, 29b will not collapse when the detection is continued for about 2 seconds, and the filling at that position is completed It is desirable to control.

  When the filling detection sensor 29a continuously detects the upper surface of the crop that is accumulated again and does not collapse for about 2 seconds, the rod of the cylinder 52a is further contracted as described above, and the container mounting table 50 is lowered while rotating a predetermined amount. . At this time, if the container detection sensor 28a of the lower transfer conveyor 20 does not detect the separation from the inner wall of the container 7L, the lower transfer conveyor 20 is again slid into the container 7L within a range where the limit detection piece 26b does not exceed the proximity sensor 46a. Perform the action.

  The above operation pattern is repeated until the bottom surface portion 50a of the container mounting table 50 reaches the lowest lowered position where the bottom surface portion 50a is parallel to the ground, and the accumulation state changes as shown in FIGS. It will be filled. When the container mounting table 50 is in the lowest lowered position, as shown in FIG. 8D, the farm products in the container 7L are accumulated in a state where the left side is a mountain and the downward slope is directed to the right. And in the lowest position, the input of the crop from the lower conveyance conveyor 20 is continued.

  When the container 7L is in the lowest position, when the upper surface of the accumulated crop is continuously detected by the filling detection sensor 29a for about 2 seconds, the lower conveyor 20 is slid to the right by a small amount. Then, the crops thrown in from the lower conveyance conveyor 20 roll on the right slope formed by the crops accumulated in the container 7L and are accumulated from below. Then, if the slope formed by the crop accumulates so as to move to the right and the crop input position no longer collapses, the filling detection sensor 29a lowers again when the crop is continuously detected for about 2 seconds. A small amount of the conveyor 20 is slid to the right.

  By repeating the sliding operation of the lower conveying conveyor 20, the accumulation upper surface of the crop is formed flat from the upper end 7c of the container 7L. At this time, the cylinder 52b starts to be extended, and the right container mounting table 50 is rotated to the highest position. When the transfer end 20a of the lower transfer conveyor 20 slides to the vicinity of the upper end 7d of the container 7L and the proximity sensor 47a detects the full detection piece 27 provided above the lower transfer conveyor 20, the filling of the container 7L is completed.

  As soon as the filling of the container 7L is completed, the turning of the upper transport conveyor 10 and the lower transport conveyor 20 is temporarily stopped, the lower transport conveyor 20 is slid rightward, and the right end thereof enters the container 7R. When the container detection sensor 28b of the lower conveyor 20 detects the inner surface of the container 7R, the slide is stopped, the upper conveyor 10 and the lower conveyor 20 are driven in reverse, that is, the conveying direction is switched to the right direction. 10th and 20th crops are put into the container 7R. Thereafter, the operation is similar to the above-described filling of the container 7L.

  Then, when the agricultural product is being carried into the container 7 </ b> R, the filled container 7 </ b> L is dropped from the container mounting table 50, and an empty container is mounted on the container mounting table 50, thereby replacing the container 7 </ b> L. Is completed. By repeating the operations described above, the containers can be filled alternately.

  During the filling operation to the container 7R as described above, the lower transfer conveyor 20 enters and enters the container 7R, so that the transfer means 5 is not positioned above the container 7L, and the container lifting operation is performed. Sometimes it is not necessary to pay attention to contact with the device, and the replacement work can be performed easily.

  Further, since the conveying means 5 is not positioned on the container to be exchanged, the tilt angle of the container is not restricted, and containers of different sizes can be used. For example, if the conveying means is a single conveyor of a certain length and the length in the conveying direction is the same as the distance between containers, the conveying means can be configured not to be positioned on the anti-filling side container, When a container larger than a certain size is used, the end of the transport means does not reach the inner part of the container, and the distance that the loaded transport object rolls on the inner surface of the container becomes long, and the transport object is damaged. Further, when the distance between the two containers is increased in design, the apparatus is also increased in size.

  In addition, the container on the filling side is inclined by about 45 °, the length of the diagonal of the container is used to make the conveying means enter long, and the conveying means is not projected on the other container, but smaller than a certain value. When a container is used, the entry distance of the conveying means is reduced, resulting in the other end protruding on the other container. In the case of agricultural products, if the tilt angle of the container is small at the initial stage of input and the slope of the throwing surface is steep, the speed of rolling in the container increases, resulting in damage and corruption. By using the filling device 1 as described above, there is no need to worry about the container replacement work, and even when containers of various sizes are initially charged, the container is tilted nearly 90 ° at the initial stage to loosen the slope of the throwing surface, It becomes possible to put it in as if it was placed with a small drop.

  Even in the case of containers for storing crops, the size may differ depending on the manufacturer and crop, and it is not uncommon to use many types of containers. The ability to use containers of different sizes without damaging the object to be conveyed as described above is a great advantage for the user.

  In addition to the above effects, if the conveying means is extendable and has a long expansion / contraction amount, the installation position of the two containers can be brought close to each other to form a compact filling device. The installation-type filling device can reduce the installation space and can be easily loaded on a mobile device such as a harvester.

  The present invention described above is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist. For example, although the example which comprised the conveying means 5 with the upper conveyance conveyor 10 and the lower conveyance conveyor 20 which are the belt conveyors of the upper and lower two steps was shown, the thing which expands-contracts three steps or more may be sufficient. Of course, the filling device is not limited to the installation type, and may be attached to a mobile vehicle such as a harvesting machine.

  In addition, although the lower conveyance conveyor 20 is configured to slide left and right at the lower stage of the upper conveyance conveyor 10, for example, two independent conveyors that slide to the left and right are provided at the lower stage of the left and right conveyance ends of the upper conveyance conveyor 10, respectively. It may be provided. Further, the slide of the lower conveyor in this case is not limited to horizontal, and for example, it may be slid and extended and contracted obliquely downward in the transport direction for the purpose of reducing the drop of the input from the transport end.

  Moreover, although the example which comprised the upper conveyance conveyor 10 with the belt conveyor was shown, the slope and chute | shoot board which can change an inclination direction like a seesaw may be used. The upper conveyor 10 and the lower conveyor 20 are not limited to belt conveyors, and may be various conveyors such as roller conveyors and vibration conveyors.

  In addition, although the conveying means 5 expansion / contraction mechanism is configured by the lower conveying conveyor 20 slidingly protruding from the upper conveying conveyor 10, the conveying means is constituted by a single belt conveyor, and pulleys at the left and right conveying ends. You may comprise so that only can move and expand and contract.
