Description

Conveyor Equipment {CONVEYOR SYSTEM}

The present invention relates to a conveyor apparatus, and more particularly, a support trolling portion is placed under the frame of a telescopic conveyor of a blanking line in a TWB (Tailor Welded Blank) facility to directly place a lower side of an endless belt. The present invention relates to a conveyor apparatus which prevents the belt from sagging in the lower direction, thereby equalizing one rotation cycle of the belt, and has flanges at both edges of the support trolling portion to prevent the belt from falling out. .

Recently, the application of TWB (Tailor Welded Blank) technology has emerged in the production of structures such as body panels of automobiles and electric vehicles, and research and development on these are being actively conducted.

The conventional method is to cut the plate and shape each, and then use the spotted point to manufacture the car body parts.TWB technology is to cut and weld iron plates of various materials and thicknesses as necessary, such as cutting a suit, and then press-form Refers to a series of techniques for manufacturing parts.

Therefore, as a result of continuous research to develop an effective, high productivity, low cost, and low weight in the automotive industry, one of them was the application of the TWB welding system. It is possible to reduce the weight and to reduce the weight, and to weld two steel sheets or several steel sheets of different strength, strength, thickness and bare and galvanized state by laser welding, and then molded in one part. Has the properties required for each site.

In particular, the blanking line of the TWB (Tailor Welded Blank) facility punches the steel plate in a desired shape and then moves to the laser welding line through the telescopic conveyor facility.

In general, as shown in the diagram schematically showing the belt operation of the telescopic conveyor of FIG. 1, the telescopic conveyor 30 is used to press the metal plate material remaining after the press-molded in the production line of the vehicle to be transported to a certain place to fall, The belt 10 is mounted between the driven roll shaft 32 and the drive roll shaft 34, and the roll shaft for tension and eccentricity adjustment of the belt 10 between the driven roll shaft 32 and the drive roll shaft 34. 12 is provided, the tension and eccentricity of the belt 10 can be adjusted by the roll shaft 12 as well as the overall length of the whole can be adjusted.

That is, when one end of the roll shaft 12 which rotates the belt 10 is not aligned with the other end exactly and is oriented to one side, the roll shaft 12 is wound around the roll shaft 12 to be rotated. A smooth rotation of the belt 10 does not proceed with the eccentricity toward the roll shaft 12 in which the belt 10 is pulled to one side, and a rotation speed difference occurs in the longitudinal direction of the roll shaft 12.

When the belt 10 is rotated and passed through the roll shaft 12, the belt 10 is eccentric to one side and is damaged by a structure installed around the belt 10 or smoothly moves the metal plate during transportation. Since it cannot be conveyed, the operator adjusts and adjusts the tension and the tension of the belt 10 from time to time.

Conventional telescopic conveyor equipment has a problem that the belt located in the lower side of the rotating belt is bent or stretched downward, resulting in time and material waste.

In addition, in the conventional telescopic conveyor equipment, the belt is wound around the roller rotates, there is a problem that is separated to the outside of the roller.

The present invention was devised to solve the above problems, and the object of the present invention is to provide a support controller below the frame of the telescopic conveyor of the blanking line of the TWB facility to directly support the lower side of the belt. As a result, the belt can be improved by transferring the belt to both edges of the support controller by reducing the downward deflection of the belt as much as possible, thereby making the belt rotation time uniform. It is to provide a conveyor apparatus to prevent.

The present invention for solving the above problems is a frame that is supported on the bottom, driven rollers are provided along the edge of the frame and are rotatably formed, respectively, a belt having a crawler shape, rotatably formed inside the frame As the belt is wound, the roller is transported when the belt is rotated by an external operation and a tension roller is provided on the lower side of the frame corresponding to the driven roller and the driven roller. Characterized by a conveyor device comprising a support trolling portion for preventing the lower side of the belt sag by supporting the lower side of the belt located between the rollers.

In addition, the conveyor apparatus according to the present invention has the effect of adjusting the tension of the belt by forming all or part of the rollers for winding the belt to be moved to the outside of the frame.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

Figure 2 is a side cross-sectional view showing the installation state of the telescopic conveyor according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing the support trolling portion of the telescopic conveyor according to an embodiment of the present invention.

And, Figure 4 and Figure 5 is an operation showing the operating state of the roller tension adjusting unit of the telescopic conveyor in accordance with an embodiment of the present invention.

As shown in Figure 2, the conveyor apparatus according to an embodiment of the present invention frame 100, driven roller 110, driving roller 120, auxiliary tension roller 130, the support trolling unit 140 and tension It consists of adjusting parts (200a, 200b).

In more detail, the frame 100 is fixedly supported on the bottom, forms the outer shape of the conveyor apparatus, driven roller 110, main roller 120, auxiliary tension roller 130, support trolling unit 140 and tension It serves to connect the control unit (200a, 200b).

In particular, the frame 100 is provided with a pair to face each other, the driven roller 110, the main roller 120, the auxiliary tension roller 130 and the support trolling unit 140 facing at least one It is interposed between the frames 100.

Preferably, all of the driven roller 110, the main roller 120, the auxiliary tension roller 130 and the support trolling unit 140 is interposed between the frame 100.

This is to prevent the narrowing of the work space as the driven roller 110, the main roller 120, the auxiliary tension roller 130 and the support trolling unit 140 protrudes to the outside of the frame 100, to be protected. .

In addition, the driven roller 110 is rotatably mounted to the frame 100, and a plurality of driven rollers 110 are provided at predetermined or irregular intervals along the edge of the frame 100.

Thus, the driven roller 110 serves to wind the belt 50 of the caterpillar shape.

That is, the belt 50 is mounted in direct contact with a portion of the outer circumferential surface of each driven roller 110.

In addition, the main roller 120 is forcibly rotated during the external operation, is rotatably mounted on the inner side of the frame 100 and the belt 50 is wound.

Therefore, the main roller 120 transmits a conveying force to the belt (50).

That is, when the main roller 120 is rotated, the belt 50 in contact with the outer circumferential surface of the main roller 120 is forcibly transferred, thereby rotating the driven roller 110 in contact with the belt 50. .

In particular, the main roller 120 is provided with one, it is directly connected to the motor 122 is to receive a rotational force when driving the motor 122.

In addition, the main roller 120 is preferably mounted on the inside of the frame 100 so as not to protrude to the outside.

This is to prevent injuries generated during forced rotation due to the exposure of the main roller 120.

Therefore, the belt 50 is bent into the frame 100 to be wound on the main roller 120, thereby maintaining a predetermined tension (tension).

Thus, the main roller 120 also serves to give tension to the belt 50 by being mounted inside the frame 100.

On the other hand, because the interval between the driven roller 110 and the distance between the driven roller 110 and the main roller 120 is spaced between the frame corresponding to the position adjacent to the driven roller 110 and the main roller 120 ( The auxiliary tension roller 130 is rotatably mounted to 100.

Thus, the belt 50 is wound around each other in the driven roller 110 and the auxiliary tension roller 130 to generate a sufficient tension.

In addition, the portion of the belt 50 passing downward of the frame 100 is not in contact with the driven roller 110 or the main roller 120 over a relatively long distance.

Accordingly, the belt 50 passing through the lower side of the frame 100 is preferably supported by the support trolling unit 140 connected to the frame 100.

In particular, the auxiliary tension roller 130 serves to maximize the tension applied to the belt 50 in contact with the driven roller 110, the main roller 120 and the support trolling unit 140.

In particular, when the shaft 141 and the support controller 142 directly contact, the support controller 142 may not be rotated by the friction with the shaft 141, so that the belt 50 at a normal speed It will not be transported.

Therefore, the bearing member 144 is interposed between the shaft 141 and the support controller 142 serves to allow the support controller 142 to rotate independently.

At this time, the bearing member 144 is preferably a ball bearing.

As a result, since the support controller 142 is in contact with the upper outer circumferential surface without being wound around the belt 50, the feeding speed of the belt 50 may be reduced due to mutual contact.

On the other hand, the shaft 141 may be mounted by inserting each end into the corresponding frame 100, but by rotating together when the support controller 142 is rotated, it is impossible to properly control the feed speed of the belt 50.

Thus, the shaft 141 is inserted into the frame 100 so that each end does not protrude to the outside of the corresponding frame 100, the frame 100 is a plate 146 on the outer surface exposed the shaft 141 In addition, the shaft 141 and the plate 146 are preferably fastened by the fastening member 148.

Therefore, the shaft 141 is prevented from rotating by being fixed by the fastening member 148.

At this time, the fastening member 148 is preferably a fastening element such as a bolt or screw.

In addition, the support controller 142 protrudes the flange 143 along the peripheral edge of both sides.

The flange 143 prevents the belt 50 spanning the support controller 142 from escaping to the outside of the support controller 142, thereby preventing the conveyance failure of the belt 50.

On the other hand, the tension control unit (200a, 200b) is at least one of the support roller 110, the main roller 120, the support trolling unit 140 of the support roller 142 and the auxiliary tension roller 130, that is, peel The roller 110, 120, 142 or 130 required to serve to adjust the tension of the belt 50 by mounting the frame 100 to be movable in the outward direction of the frame 100.

That is, at least one of the central axis 112 of the driven roller 110, the central axis 124 of the main roller 120, the central axis 132 of the auxiliary tension roller 130 and the support controller 142. The roller is provided with tension adjusting parts 200a and 200b.

In particular, as an embodiment, the tension adjusting unit 200a, 200b according to the present invention is presented in two ways, but may be modified in various forms.

In addition, the position shifting member 214 is composed of a pair inserted into both sides of the frame 100 to be in line with the long diameter of the long hole 212.

Thus, the pair of position moving members 214 are in contact with both circumferential surfaces opposite to each other based on the center of the central axis 112 of the driven roller 110.

Accordingly, when the central axis 112 is moved by pushing any one of the pair of position shifting members 214, the other position shifting member 214 is driven by an external force or naturally. It is moved by the movement of 112).

At this time, since the driven roller 110 is wound on the belt 50, a pair of position shifting members 214 are framed as a force is generated to push the inner side of the frame 100 together with the central axis 112. It must be inserted and fixed in position.

In more detail, the frame 100 passes through the insertion hole 216 so as to insert each of the pair of position moving members 214, and the tab 217 is formed on the inner surface of the insertion hole 216.

In addition, the pair of position shifting members 214 are changed in the insertion hole 216 as the tabs 215 are formed on the circumferential surface thereof so as to be engaged with the tabs 217 formed in the insertion holes 216. Will be maintained.

As shown in FIG. 5, the tension adjusting part 200b according to another embodiment of the present invention includes a long hole part 222, a coupling hole part 223, a bracket 225, and a binding member 227.

For convenience, the long hole 222 is formed in the frame 100 to move the auxiliary tension roller 130 in the lower direction of the frame 100 to adjust the tension of the belt 50.

Of course, at least one of the driven roller 110, the main roller 120, the support controller 142 and the auxiliary tension roller 130 may be mounted to be movable along the long diameter inside the long hole 222. .

In particular, the long hole 222 is formed in a rectangular shape to adjust the tension while pulling the belt 50 by moving the auxiliary tension roller 130 in the lower direction of the frame 100.

At this time, the central axis 132 of the auxiliary tension roller 130 is inserted into the long hole 222 is moved by an external force.

Here, the central axis 132 of the auxiliary tension roller 130 is formed in an angular shape so as not to rotate inside the long hole 222.

In addition, the coupling hole 223 is formed through the central axis 132.

In more detail, the coupling hole 223 is formed in the central axis 132 to be parallel to the long hole 222.

In addition, the coupling hole 223 forms a tab 224 on the inner surface.

In addition, the bracket 225 is formed on the side of the frame 100, and forms the through-hole communication hole 226 so as to be in line with the coupling hole 223.

At this time, the bracket 225 is preferably formed detachably to the frame 100 for maintenance.

In addition, the binding member 227 is inserted into the communication hole 226 of the bracket 225, and forms a tab 228 on the circumferential surface.

Thus, the binding member 227 is coupled to the central axis 132 of the auxiliary tension roller 130 while the tab 228 is engaged with the tab 224 of the coupling hole 223.

At this time, the binding member 227 is a fastening element such as a bolt or screw.

Therefore, when the binding member 227 is rotated by an external force in a state where it is no longer raised by the bracket 225, the central axis 132 and the auxiliary tension roller 130 connected to the central axis 132 is It moves along the axial direction of the binding member 227.

As a result, the auxiliary tension roller 130 is provided to give a tension to the belt 50 while moving in the lower direction of the frame 100, or to adjust the tension of the belt 50 while moving in the upper direction of the frame 100 do.
