Description
Description AUTOMATIC CONVEYING AND DISCHARGING APPARATUS
Technical Field
[1] The present invention relates to an automatic conveying and discharging apparatus; and more particularly, to an automatic conveying and discharging apparatus for quickly and accurately conveying different sizes and shapes of loads to a predetermined location of a roll conveyer or a rail unit regardless of locations thereof by lifting up the load using a moving carrier and conveying the lifted-up load to the predetermined location without disturbing other loads, and having a structure for securing space for easy installation in order to allow economic installation. Background Art
[2] Sheet material is generally supplied as a roll. In order to process the sheet material, the sheet material is unrolled from the roll, and the unrolled sheet is conveyed to a processing machine such as a steel sheet processing machine. The processing machine cuts the sheet material in various shapes and stacks the processed sheets according to the sizes thereof. Then, the stacked sheets are conveyed to a loading place. After cutting the unrolled sheet, the processing machine may discharge the sheet.
[3] A roller conveyer or a belt conveyer is generally used as a conventional apparatus for supplying and discharging a sheet material. Hereinafter, the roller conveyer is described as an example of the conventional apparatus for supplying and discharging the sheet material.
[4] After the sheep processing machine cuts and stacks the sheet material, the processed sheets are placed on the roller conveyer which is automatically rotated by man power or mechanical driving force, and the roller conveyer conveys the processed sheets to the loading place or the discharging place.
[5] However, the roller conveyer has a shortcoming that the roller conveyer sequentially discharges the loads in the order of placing the loads on the roller conveyer only. That is, the roller conveyer discharges the loads only in a first- in first-out manner.
[6] That is, loads cannot be appropriately placed on the roller conveyer or differently discharged from the roller conveyer according to its size or shape when various loads having different lengths and shapes are placed on random locations of the roller conveyer.
[7] After placing loads on the roller conveyer, the loads maintain positions thereof until they are discharged. Therefore, the durability thereof is degraded due to the weight. Also, it is difficult to detect the locations of the loads and the loads are scattered on the
roller conveyer. Therefore, the operation efficiency is degraded.
[8] Moreover, large space is required to secure a passage for a fork-lift for lifting up and placing a heavy load on the roller conveyer. Disclosure of Invention

according to an embodiment of the present invention.
[48] Referring to FIG. 3, the forward/backward driving unit 22 according to the present embodiment includes a link chain 24, link chain sprockets 54 and a driving motor 56. The link chain 24 such a wire is disposed as long as the length of the rail 4 to be connected to the wheel unit 12. The link chain sprockets 54 such as a wire-poly are disposed to be separated at a predetermined distance, and the link chain 24 is arranged to wind around the link chain sprockets 54. The driving motor 56 drives the link chain sprockets 54 to be rotated.
[49] FIG. 4 is a view of a moving carrier holding a load according to an embodiment of the present invention, and FIG. 5 is a view of a moving carrier lifting up a load according to an embodiment of the present invention.
[50] Hereinafter, the operations of the automatic conveying and discharging apparatus 2 according to the present embodiment will be described with reference to FIGs 4 and 5.
[51] Referring to FIGs. 4 and 5, the automatic conveying and discharging apparatus 2 according to the present embodiment conveys a load supplied from the supply conveyer 4 to a predetermined location of the rail 6 through the roller conveyer 8.
[52] For example, a plurality of the rail units 6 may be arranged to be adaptable to a manufacturing environment, such as a first rail unit, a second rail unit and so on. That is, the number of the rail units 6 may vary according to the manufacturing environment.
[53] Then, the driving motor 56 of the forward/backward driving unit 22 rotates the link chain sprockets 54 such as the wire-poly to move the link chain 24 such as the wire in a predetermined direction in order to move the moving carrier 10 located on one of the rail units 6 where the load is placed on the roller conveyer 8 to a predetermined position.
[54] The predetermined position of the moving carrier 10 is determined using sensing units such as a typical encoder or a sensor.
[55] When the moving carrier 10 is located on the load, the hoist 46 of the hoist unit 20 lowers the elevating plate 32 to locate at the rail. Then, the motor 34 is driven to rotate the screw bar 36 to lower the supporting bar 38. Then, the finger holders 40 are inserted into the entering holes 42 while lowering the supporting bar 38.
[56] When completely lowering the supporting bar 38, the finger holders 40 are inserted into the holes of the pallet of the load or under the load.
[57] After completely inserting the finger holders 40 into the holes of the pallet or under the load, the hoist 46 of the hoist unit 20 is driven to roll up the link chain 52, and the elevating plate 32 is, accordingly, raised in balance. That is, the elevating plate 32 lifts up the load to reach the side reinforcing plate 16.
[58] Since the finger holders 40 are supported by the supporting members 44 of the
entering holes 42 formed at the lower portion of the elevating plate 32, the finger holders 40 are not outwardly bended while lifting up the load. Therefore, the load can be lifted up by the finger holders 40 disposed at the elevating plate 32.
[59] After the moving carrier 10 completely lifts up the load, the forward/backward driving unit 22 moves the moving carrier 10 to a predetermined location of the rail unit 6.
[60] When the moving carrier 10 moves to the predetermined location of the rail unit 6, the hoist unit 20 lowers the elevating plate 32 to place the load that is holed by the finger holders 40 on the predetermined location of the rail unit 6.
[61] When the load is placed on the predetermined location of the rail unit 6 as described above, the motor 34 of the elevating plate 32 is driven to rotate the screw bar 36 to rise the supporting bar 38. Then, the finger holders 40 come out from the supporting members 44 through the entering holes 42 and are raised to be located at the side surface of the elevating plate 32.
[62] The conveying operation of the moving carrier 10 ends when the finger holders 40 are placed at the side surface of the elevating plate 32. The moving carrier 10 waits for a next conveying operation.
[63] As described above, the elevating plates 32 are connected to the hoists 46 of the hoist units 20, and it is possible to control the elevating plates 32, the hoist units 20 and the forward/backward driving unit 22 using a controller (not shown) such a computer.
[64] Each of the finger holders 10 is consisted of a plurality of joints connected through hinges. When the finger holders 10 are lowered with the elevating plate 32 in order to lift up the load, each of the joints of the finger holders 10 is inwardly bended and located under the load. Herein, the hinges of the finger holders 10 allow the joints to be rotated in one direction only. Therefore, after the finger holders 10 are placed under the load, the finger holders 10 can support the load to lift up because the hinges restrict the joints of the finger holders from being outwardly bended.
[65] As described above, the automatic conveying and discharging apparatus 2 according to the present invention may lift up the load with the pallet or the load only. For example, when a load is placed on a pallet 58 having a plurality of convex members and a plurality of concave member which are alternatively formed at a predetermined distance on the bottom of the pallet 58, the automatic conveying and discharging apparatus 2 lifts up the load with the pallet by inserting the finger holders 40 under the convex members of the pallet 58. Or the automatic conveying and discharging apparatus 2 lifts up the load only by inserting the finger holders 40 above the concave members of the pallet 58.
[66] Therefore, the automatic conveying and discharging apparatus 2 according to the present invention can place various sizes or shapes of loads on predetermined different
locations or can discharges various sizes or shapes of loads placed on different locations without being disturbed by other loads.
[67] While the present invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
