Description

APPARATUS FOR DISTRIBUTING AND PROVIDING LOAD

Technical Field

[1] The present invention relates to an apparatus for distributing and providing a load; and more particularly, to an apparatus for distributing and providing a load, which is capable of effectively loading a paper roll and sufficiently securing a traffic line of a clamp forklift by disposing a guide groove rail formed to be diverged from one receiving end to a plurality of destination ends and diagonally disposing a load providing unit to the receiving end of the guide groove rail in order to smoothly provide the paper roll to carts, and has a simple structure by disposing the guide groove rail so as to provide economic benefits such as a low installation cost and a reduced manufacturing cost through reducing the number of process and the number of parts. Background Art

[2] Generally, a paper roll is supplied to a printing machine or a corrugated paper manufacturing machine as a raw material.

[3] Since the paper roll is generally heavy and huge, a forklift or a crane is used to lift the paper roll up and loads the paper roll on a conveyor connected to the printing machine or the corrugated paper manufacturing machine.

[4] However, the printing machine or the corrugate manufacturing machine consumes various paper rolls which are different in a size and a form. Therefore, different loading equipments such as a forklift or a crane are required to lift up or to load the various paper rolls to the printing machine or the corrugate manufacturing machine according to the size and the form of the roll paper.

[5] If different loading equipments are used to supply the paper roll according to the size and the form of the paper roll, it requires a longer operating time and more man power to supply the paper roll to the printing machine or the corrugated paper manufacturing machine. Therefore, productivity is degraded.

[6] In order to overcome such an obstacle, a conventional roll paper conveying apparatus was introduced by the applicant of the present invention in Korea Patent Application No. 2004-0099127 and No. 2004-0159091.

[7] The conventional paper roll conveying apparatus has disadvantages such as difficulties for securing a traffic line of a clamp forklift around the conveying apparatus because a huge space is required to supply the paper roll using the clamp forklift.

[8] Also, the convention paper roll conveying apparatus has a complicated structure assembled of numerous parts which increases an installation cost of the printing machine or the corrugated paper manufacturing machine. As a result, a manufacturing cost of a product increases too. Disclosure of Invention

Each of the line rail grooves 18 and 20 includes a guide groove 32 formed in the ground and guide frames 34 buried in the guide groove 32 to be stacked one on another in the guide groove 32. [47] The guide groove rail 8 is formed to allow the carts 10 to departure from and to return to a same location. That is, the first line rail groove 18 and the second line rail groove 20 are closely arranged at the departure location and the return location in order to place the cart 10 at the same location. [48] In other words, the guide groove rail 8 is formed to allow the cart 10 to reach different destination locations although the carts return at a same location. [49] FIG. 4 is a perspective view of the cart 10, FIG. 5 is a plan view of the cart 10 and

FIG. 6 is a cross-sectional view of the cart 10. [50] Referring to FIGs. 4 to 6, the cart 10 is disposed to alternatively travel along the guide groove rail 8 in order to convey the paper rolls. [51] The cart 10 includes base frames 36, a fixing plate 38, a steering plate 40, a wheel unit 42, a guide roller 44 and a link-chain ring 46. [52] The base frames are disposed in parallel to be separated at a predetermined distance in order to stably load the paper roll 16 without shaking. Each of the base frames has a predetermined length, and supporting protrusions 48 formed at both ends thereof to face one another. [53] The fixing plate 38 is formed to secure a predetermined area to fix the base frames thereto. Such a fixing plate 38 is not limited by a shape. That is, the fixing plate 38 may be formed in various shapes according to a design. The fixing plates 38 are fixed at bottoms of both ends of the base frames are fixed. [54] The steering plate 40 is formed in an extended shape of the fixing plate 38. The steering plate 40 is rotatably assembled at the bottom of the fixing plate 38 through a rotation shaft 50, and a plurality of bearings is interposed between the steering plate 40 and the fixing plate 38. In order to reduce a friction force between the fixing plate 38 and the steering plate 40, metal balls 54 are interposed in a shape of a ring. [55] The wheel unit 42 is disposed at the steering plate 40 and includes an external wheel 56 and two internal wheels 58 based on the base frame 36. [56] When the wheel unit 42 goes over the guide groove rail 8, the wheel unit 42 may be caught by the guide groove rail 8 or damaged by the impact made by the weight of the paper roll. The wheel unit 42 includes two internal wheels 58 in order to prevent the wheel unit 42 from being caught or damaged. [57] The guide roller 44 is disposed at the bottom of the steering plate 40 horizontally to a supporting shaft 60 in order to guide the cart 10 to travel and to return along the guide groove 32. [58] The guide roller 44 turns the steering plate 40 at a predetermined angle according to a traveling direction of the cart 10 in order to dynamically control the wheel unit 42 according to the traveling direction of the cart 10.

[59] The link chain ring 46 is disposed at a bottom extended from the rotation shaft 50 to pull the cart 10.

[60] The link chain ring 46 is formed at a level below the wheel unit 42 to effectively generate a pulling power to pull the cart 10.

[61] In order to reduce the number of parts and the number of processes, the guide groove rail 8 is provided and the guide groove rail 8 is disposed at front of a load- taking-in plate 62 of the load providing unit 14. The guide groove rail 8 allows the carts 10 to return to a same location after finishing operations.

[62] FIG. 7 is a cross-section view illustrating a driving unit of the chat 10.

[63] Referring to FIG. 7, the driving unit 12 is disposed to be buried in order to selectively drive the carts 10 along the guide groove rail 8 according to preset information.

[64] The driving unit 12 includes a link chain 64 disposed to be guided along the guide frame 34 in the guide groove rail 8, and both ends of the link-chain 64 are connected to the link-chain rings 46 formed at a front and a back of the cart 10, respectively.

[65] The driving unit 12 further includes link-chain sprockets 66 disposed at both sides thereof to be surrounded by the link chain 64, and a driving motor 68 for transferring a power to one of the link chain sprockets 66.

[66] FIG. 8 is a view illustrating the load providing unit, and FIG. 9 is a plan view of the load providing unit.

[67] Referring to FIGs. 8 and 9, the load providing unit 14 is diagonally disposed at a receiving end of the guide groove rail 8 where the cart 10 receives the paper roll 16.

[68] The load providing unit 14 is diagonally arranged from the guide groove rail 8 at a predetermined angle and includes a loading unit 70 and a load-taking-in plate 62.

[69] The loading unit 70 includes lifters 72 for rising and loading a paper roll 16 on the cart 10 located at the loading guiding region 30 of the guide groove rail 8, a circumference supporting roller 74 disposed between the lifters 72 at the first line rail groove side, and a taper supporting roller 76 disposed between the lifters 72 at the second line rail groove side to be parallel from the circumference supporting roller 74.

[70] The load-taking-in plate 62 is disposed vertically to the circumference of the taper supporting roller 76 of the loading unit 70 and is diagonally disposed from the loading unit 70 at a predetermined angle. A distributing unit 78 is disposed to be near the loading unit 70 and a load-pushing unit 80 is installed to be separated from the distributing unit 78 at a predetermined distance in order to convey a huge material or a large paper roll to the loading unit 70 through the load-taking-in plate 62.

[71] The distributing unit 78 stops the paper roll 16 conveyed along the load-taking-in plate 62 by the load-pushing unit 80 by lifting up a stopper 88 configured of a derail preventing member 82, a moving restricting member 84 and a buffering member 86. The stopper 88 is dynamically operated by a cylinder 90.

[72] The load-pushing unit 80 pushes up the paper roll 16 transshipped from a clamp forklift to the distributing unit 78 by lifting up a second operating plate 94 with a first operating plate 96 using a cylinder 92.

[73] The lifter 72 or the cylinder 90 in the distributing and providing apparatus 2 may be selectively uses one of an oil pressure and an air pressure. Also, one of the units in the distributing and providing apparatus 2 may be use an electric power according to a design thereof.

[74] Hereinafter, the operations of the apparatus for distributing and providing a load according to the present invention will be described. In a manufacturing field with the distributing and providing apparatus disposed, a clamp forklift loads a paper roll 16 on the load-taking-in plate 62 of the load providing unit 14.

[75] The distributing unit 78 stably holds the paper roll 16 using the moving restriction member 84 and the derail preventing member 82. Then, the distributing unit 78 pushes the paper roll 16 to the guide groove rail 8 to place the paper roll 16 between the loading guiding region 30 at a predetermined time before the cart 10 returns at the receiving location. Generally, the distributing unit 78 pushes the paper roll 16 to place the paper roll 16 between the loading guiding region 30 after the cart 10 leaves from the receiving location and before the cart 10 returns to the receiving location.

[76] The distributing unit 78 stably provides the paper rolls by repeatedly stopping and pushing the paper rolls 16.

[77] That is, the paper roll 16 travels to the distributing unit 78 along the load-taking-in plate 62 and is stopped by the distributing unit 78. The paper roll 16 is stably maintained using the moving restriction member 84 and the derail preventing unit 82. Then, the distributing unit 78 pushes the paper roll 16 to continuously travel to the taper supporting roller 76. When the paper roll 16 reaches the taper supporting roller 76, the taper supporting roller 76 turns the traveling direction of the paper roll 16. Then, the circumference supporting roller 74 and the taper supporting roller 76 conveys the paper roll 16 to the guide groove rail 8.

[78] The lifters 72 rise up the paper roll 16 from the taper supporting roller 76 and the circumference supporting roller 74. Then, the cart 10 enters in the loading guiding region 30 of the guide groove rail 8 where the circumference supporting roller 74 and the taper supporting roller 76 are disposed.

[79] After the cart 10 completely enters and stops at the loading guiding region 30, the lifters 72 puts the paper roll 16 on the cart 10 and returns to the initial state in order to allow the cart 10 to smoothly travel along the guide groove rail 8. [80] Since the paper roll 16 seats on the base frames 36 with the supporting protrusions

48, the cart 10 stably holds the paper roll 16 without shaking.

[81] Then, the driving unit 12 moves the cart 10 with the paper roll 16 loaded to the temporal pick-up unit 6 by driving the driving motor 68 to turn the link chain 64 attached to the cart 10.

[82] The temporal pick-up unit 6 picks up the paper roll 16 and loads the paper roll on the carrier turntable 22. The carrier turntable 22 conveys the paper roll at a predetermined distance and turns the conveying direction of the paper roll. Then, the paper roll 16 is transshipped to a next conveyor to convey to a final destination location.

[83] When the paper roll 16 is loaded on the cart 10, the driving unit 12 drives the driving motor 68 disposed at one side of the guide groove rail 8 to turn the link chain 64. Since the link chain 64 is winded around the link chain sprockets 66 disposed at the both ends of the guide groove rail 8, is guided along the guide frame 34 and is attached at the cart 10 through the link chain ring 46 extended from the rotation shaft 50, the driving unit 12 pulls the cart 10.

[84] The cart 10 is pulled no matter where the cart 10 is on the guide groove rail 8.

[85] That is, the cart 10 with the paper roll loaded travels in a forward direction from the loading guiding region 30 by pulling the link chain ring 46. Herein, the guide roller 44 disposed at a front side of the supporting shaft 60 of the steering plate 40 of the cart 10 guides the cart 10 to travel along the guide groove rail 8 to the loading guiding region 30 of the first line rail groove 18. Therefore, the cart 10 travels forwardly and backwardly along the first line rail groove 18, only.

[86] As described above, the guide groove rail 8 is formed to be diverged to different destination locations from a single departure location. That is, the guide groove rail 8 is diverged to allow the cart to reach different angle changing devices and to return a same receiving location. Therefore, it is possible to install the apparatus for distributing and providing the load according to the present invention with a low installation cost.

[87] If the cart 10 enters the diverge guiding region 28 after traveling along the loading guiding region 30, the cart 10 stably crosses the second line rail groove 20 using two internal wheels 58 in order to reach to the pick-up guiding region 26.

[88] Then, the temporal pick-up unit 6 lifts the paper roll 16 from the cart 10 at the pickup guiding region 26 of the guide groove rail 8. After the temporal pick-up unit 6 lifts the paper roll 16 up, the driving unit 12 controls the driving motor 68 to turn the link chain sprocket 66 to pull the link chain 64. Then, the cart 10 returns to the loading unit 70 along the first line rail groove 18 by the guide roller 44 at the rear side.

[89] Another cart 10 travels on the second line rail groove 20 alternatively from the cart

10 traveling on the first line rail groove 18 through performing same operations. [90] The driving unit 12 may be separated installed for each of the carts 10 or may be installed to control the carts 10 alternatively in order to allow the carts 10 to alternatively travel forwardly and backwardly without interfered each others.

[91] Since the cart 10 on the second line rail groove 20 is operated through same processes compared to the cart 10 on the first line rail groove 18, details thereof are omitted.

[92] 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.
