【Example】

Next, an embodiment of the present invention will be described with reference to the drawings. Supports 1 and 2 are erected on the left and right sides with a distance wider than the left and right width of the pallet P. Both pillars 1 , 2 is supported on the ground by supports 3 and 4 extending in the front and back direction, and is slightly above the supports 3 and 4. On the other hand, the left and right pillars 1 and 2 are integrally connected by a connecting frame 5. Pillar 1 , 2 has a square cylindrical shape and supports sprockets 6 and 7 at the top and bottom of the inside, respectively, and a chain 8. is wrapped around it. The lower sprockets 6 and 6 are rotary shafts supported between the supports 1 and 2. It is fixed to the rotating shaft 9. Another sprocket 10 is fixed to this rotating shaft 9, and A sprocket fixed to the output shaft of the motor 11 with a deceleration brake mounted on the connection frame 5. A chain 13 is wound between the chain 12 and the jacket 12 to receive power transmission.

[0007] Rails 14 are attached to both the left and right sides of the pillars 1 and 2, and the rails 14 are An elevating support stand 15 is attached to a chain 8 within the columns 1 and 2 so that it can move up and down. The left and right lifting supports 15, 15 are integrally fixed by a connecting frame 16, and connected to this connecting frame 16. A horizontal guide rail 17 is attached with bolts 18.

[0008] The horizontal guide rail 17 is installed with one side protruding largely to the side as shown in the figure. However, on the protruding side, the mounting position of the horizontal guide rail 17 to the connecting frame 16 must be changed. By doing this, it can be changed on either the right or left side. The horizontal guide rail 17 is connected to the support column 1, Similar to 2, it has a hollow rectangular cylindrical shape and has sprockets 19 and 20 pivoted on both left and right ends inside. Chain 21 is wrapped around it. Also, a deceleration block is installed at one end of this horizontal guide rail 17. Attach the motor 22 with a rake and attach one of the sprockets 20 to its output shaft. It is attached. Furthermore, rails 23 are installed on the upper and lower sides of this horizontal guide rail 17. The movable support base 24 is attached to the internal chain so that it can move left and right along this rail 23. It is attached to 21.

[0009] The movable frame 25 is attached to the movable support base 24, but the attachment is done by the base 26. is made rotatable with a pin 27 and fixed with a bolt 28, and when the bolt 28 is removed, it can be moved. The movable frame 25 can be rotated from a state where it protrudes forward to a state where it follows the horizontal guide rail 17. I try to do that. Furthermore, a motor 29 with a deceleration brake is attached to the base 26. Ru.

0010 The movable frame 25 is a shaped steel 30 having a substantially U-shaped cross section, and has a pulley 3 pivoted at its internal tip. 1 and a pulley 32 attached to the output shaft of the motor 29. 33 is wrapped around it. Pulleys 31, 32 and timing belt 33 are endless band transmission The mechanism 120 is composed of a sprocket and a chain. Sometimes I do. With this movable frame 25 sandwiched between the rollers 34 and 35 from above and below, the support stand 36 is I am wearing it. This hanging support stand 36 is attached to the timing belt 33 inside the steel mold 30. The timing belt 33 is connected with the connecting tool 37, and when the timing belt 33 moves, it becomes a hanging support stand. 36 moves back and forth on the moving frame 25. 38 is the opening side of the shaped steel 30. With a cover to cover, fit the roller 40 onto the mounting pin 39 of this cover 38 and set the timing. This is a guide to prevent the belt 33 from sagging.

[0011] The article holder 110 is constructed as follows. A hanging frame 41 is rotatably suspended from the lower part of the hanging support stand 36 using a support shaft 42. I'm growing up. On the upper side of the hanging frame 41, the frame 41 is rotated around a support shaft 42. A rotating electric cylinder 43 for rotating and an opening/closing cylinder for operating an opening/closing mechanism to be described later. An electric cylinder 44 is attached. The rod tip of the rotating electric cylinder 43 is , is connected to a shaft 45 extending downward from the hanging support 36, and this electric cylinder 4 The suspension frame 41 rotates by 90° by the expansion and contraction of step 3.

0012 Two rotating shafts 46 and 47 are supported through the hanging frame 41, and both rotating shafts 46 , 47, plate-shaped brackets 48, 49 are fixed to both ends thereof. Brackets 48 and 49 The side view shape is approximately triangular, and an outer opening/closing frame 50 is attached to each outer lower end, The upper and inner lower parts of both brackets 48 and 49 are connected by links 51 and 52, respectively. The inner opening/closing frame 53 is attached to the lower end of both links 51 and 52. . The outer opening/closing frame 50 has a fork-shaped scooping body bent inward in an L-shape. 54 are attached at predetermined intervals to scoop out the underside of the article. inner opening/closing frame 53, it points straight downward, the lower end bends slightly inward, and the lowest end points outward and downward. A guide body 55 having a shape similar to that shown in FIG.

[0013] The upper part of one bracket 48 and the rod tip of the opening/closing electric cylinder 44 are connected by a link 56. Such an electric cylinder 44 and brackets 48, 49 The electric cylinder 44 expands and contracts with a structure in which these are connected by links 51, 52, and 56. Then, the guide body 55 moves in and out in parallel, and the scooping body 54 moves around the rotating shafts 46 and 47. You will move inward and outward with your mind in mind.

[0014] A pallet transfer device 60 is arranged between the left and right supports 3 and 4 on the ground. The pallet transfer device 60 rotates around a frame 61 made of band iron, shaped steel, etc. Rotating shafts 62 and 63 are supported, and chains 64 and 64 are wound around the front and back on both left and right sides. Attach sprockets 65 and 66 to the rotating shafts 62 and 63, and A motor 67 with a deceleration brake is connected to the end of the shaft 2. Also, frame 61 The front and rear portions are connected to each other by a pivot shaft 68 so as to be bendable at substantially intermediate positions. The front and rear horizontal frames 69 and 70 that constitute the frame 61 are brought into contact with the inside of the supports 3 and 4. It is fixed with bolts 71 and also serves as reinforcement for the columns 1 and 2.

[0015] On the rear side of the main body, there is a pallet that feeds pallets P one by one onto the pallet transfer device 60. A let supply device 80 is installed. The pallet supply device 80 stacks pallets P and rotates the handle 81. Then, the pallets P fall one by one, slide on the downward inclined roller conveyor 82, and the pallets P fall down one by one. The pallet is moved onto the pallet transfer device 60 and is sent to a predetermined position by the movement of the chain 64. P stops.

[0016] Items such as paddy bags are placed on the side A of the horizontal guide rail 17 that protrudes beyond the pillars 1 and 2. supply. Move the hanging frame 41 above this article and scoop it with the scooping body 54. Raise the item, move it onto the pallet P, and scoop it up while regulating the falling position with the guide body 55. The scraping body 54 is opened, dropped, and placed on a predetermined position on the pallet P. After stacking items on pallet P in multiple stages, use a forklift from the front to palletize them. This involves scooping up the kit P and moving it to a predetermined position in the warehouse.
