1 to 9, the roller processing apparatus 100 according to the first embodiment of the present invention includes a supply guide portion 101, a preheating portion 102, a welding portion 103, a discharge guide portion 104 The roller 10 including the supply control portion 105, the roller forming portion 106, the roller collecting portion 107, the collecting guide portion 108, the collecting / moving portion 109 and the roller reinforcing portion 110, As shown in Fig.

The roller 10 may be applied to a caterpillar, a conveyor belt, or the like, and may have a cylindrical shape. The roller 10 includes a pair of body portions 11 and a connecting portion 12, the body portions 11 each having a cylindrical shape and having an insertion groove 11a formed along the outer peripheral surface thereof, The connecting portion 12 is formed in a planar cross-section in each of the body portions 11 and is coupled to each other to connect the body portions 11. [ Here, the roller 10 is formed into a cylindrical shape by the body portions 11, and the connecting portion 12 is located between the body portions 11. [

The supply guide portion 101 is positioned along the one direction A. Here, the one direction A is a direction corresponding to the conveying direction of the roller 10. [ The roller 10 is positioned on the supply guide portion 101 and the central axis of the roller 10 is positioned in the horizontal direction so as to intersect the one direction A. [ Here, the central axis of the roller 10 means a virtual axis connecting the center of the body portion 11. [ The supply guide portion 101 can feed the roller 10 along the one direction A. [ The roller 10 may be guided along the supply guide portion 101 to the preheating portion 102.

The supply guide portions 101 are formed as a pair and each have a bar shape. These supply guide portions 101 are located along one direction A and are spaced apart from each other in parallel. When the roller 10 is positioned on the supply guide portion 101, a part of the supply guide portion 101 is inserted into the insertion groove 11a of the body portion 11 and the connection portion 12 is inserted into the supply guide portion 101 101, respectively. The roller 10 can be transported in the one direction A along the supply guide portion 101 without being separated from the supply guide portion 101. [

The supply guide portion 101 can be inclined. For example, the leading end portion of the feeding guide portion 101 may move upward and be positioned above the rear end portion of the feeding guide portion 101. The front end of the supply guide portion 101 is the end portion of the supply guide portion 101 where the roller 10 starts to flow and the rear end portion of the supply guide portion 101 is the supply guide portion 101 adjacent to the preheating portion 102, (101). As a result, the supply guide portion 101 is gradually inclined downward along the one direction A (i.e., closer to the preheating portion 102). The roller 10 positioned in the supply guide portion 101 can be naturally transferred along the supply guide portion 101 in one direction A and guided to the preheating portion 102.

The supply control unit 105 is located at the rear end of the supply guide unit 101 and guides the rollers 10 positioned on the supply guide unit 101 to the preheating unit 102 one by one. The supply control unit 105 includes a main control unit 151 and a sub-control unit 153. [

The main control unit 151 is located on the upper side of the supply guide unit 101 so as to be adjacent to the preheating unit 102 and can be moved up and down with respect to the upper surface of the supply guide unit 101. [

For example, when the main control unit 151 is moved downward and contacts the upper surface of the supply guide unit 101, the roller 10 may not be transported toward the preheating unit 102 by the main control unit 151 On the other hand, when the main control portion 151 is moved upward to be spaced from the upper surface of the supply guide portion 101 so as to correspond to the diameter of the roller 10, the roller 10 can be transported toward the preheating portion 102 .

The sub control unit 153 is located above the supply guide unit 101 so as to be spaced apart from the main control unit 151 in correspondence to the diameter of the roller 10. [ Here, the main control unit 151 is located between the preheating unit 102 and the sub control unit 153. The sub control unit 153 can also be moved up and down with respect to the upper surface of the supply guide unit 101 like the main control unit 151. [

For example, when the sub control unit 153 is moved downward and contacts the upper surface of the supply guide unit 101, the roller 10 may not be transported toward the preheating unit 102 by the sub control unit 153 On the other hand, when the sub-control portion 153 is moved upward and separated from the upper surface of the supply guide portion 101 so as to correspond to the diameter of the roller 10, the roller 10 can be transported toward the preheating portion 102 .

When the supply guide portion 101 is gradually tilted downward along the one direction A (i.e., closer to the preheating portion 102) with the rollers 10 positioned in the supply guide portion 101, (10) are moved toward the preheating section (102) along the supply guide section (101). At this time, the main control unit 151 is moved downward to be brought into contact with the upper surface of the supply guide unit 101, and the sub control unit 153 is moved upward, so as to correspond to the diameter of the roller 10, And is spaced from the upper surface. As a result, one of the rollers 10 in the supply guide portion 101 comes into contact with the main control portion 151 and stops, and stops the remaining rollers 10. In addition, the sub control unit 153 is moved downward, inserted between the rollers 10, and brought into contact with the upper surface of the supply guide unit 101. Thus, the roller 10 that is in contact with the main control unit 151 is also brought into contact with the sub control unit 153 as well. One roller 10 is positioned between the main control unit 151 and the sub control unit 153. [ Further, the supply guide portion 101 may not be inclined.

When the roller 10 is discharged from the preheating section 102 after being heated in the preheating section 102, the supply guide section 101 moves along one direction A (i.e., closer to the preheating section 102) The main control portion 151 is moved upward and is spaced from the upper surface of the supply guide portion 101 so as to correspond to the diameter of the roller 10. [ Therefore, only the roller 10 between the main control unit 151 and the sub control unit 153 is guided to the preheating unit 102 along the supply guide unit 101.

After the roller 10 is guided to the preheating portion 102, the main control portion 151 is moved downward to be brought into contact with the upper surface of the supply guide portion 101, and the sub control portion 153 is moved upward, 10 from the upper surface of the supply guide portion 101 so as to correspond to the diameter of the supply guide portion 101. The roller 10 is conveyed along the supply guide portion 101 and passes under the sub control portion 153 and contacts the main control portion 151. [ At this time, the sub control unit 153 is moved downward and contacts the upper surface of the supply guide unit 101 to place the roller 10, which is in contact with the main control unit 151, between the main control unit 151 and the sub control unit 153 .

The main controller 151 and the sub controller 153 are combined with each other so that the rollers 10 can be guided from the supply guide unit 101 to the preheating unit 102 one by one.

When the roller 10 is guided and positioned in the preheating portion 102, the leading end portion of the supply guide portion 101 moves downward so that the supply guide portion 101 is not tilted, 102). ≪ / RTI >

The preheating section 102 is connected to the supply guide section 101 and is positioned along the one direction A and receives the roller 10 conveyed from the supply guide section 101. The roller 10 is positioned on the preheating section 102 and the preheating section 102 rotates the roller 10 about the connecting section 12. At this time, the preheating section 102 heats the roller 10 about the roller 10, especially the connecting portion 12. Here, the connecting portion 12 is specifically a portion to be welded by the welding portion 103 described later.

The preheating section 102 increases the temperature of the connecting section 12 and the temperature of a part of the body section 11 adjacent to the connecting section 12 by heating the roller 10 so that the cooling rate Can be reduced. As a result, the hardness of the heat affected portion due to welding at the connection portion 12 is reduced, and the toughness of the heat affected portion is increased. The mechanical properties of the connecting portion 12 are improved through welding, the deposition of the hardened structure in the connecting portion 12 is prevented, and the strain and the residual stress can be alleviated.

The preheating section 102 includes a preheating drive section 121, a preheating body section 123, and a preheating transfer section 125.

The preheating drive unit 121 is arranged in pairs in the one direction A to correspond to the supply guide unit 101. [ The supply guide portions 101 of the present embodiment are formed as a pair, and are spaced apart from each other in parallel and positioned in a single direction (A), so that the preheating drive portion 121 is four. Each of the preheating drive parts 121 is formed in a circular plate shape. Further, the preheating drive parts 121 arranged in pairs in the one direction A have an outer circumferential surface positioned adjacent to each other, and have a central axis (that is, a rotation axis) positioned in parallel with each other.

When the roller 10 is guided from the supply guide portion 101 to the preheating portion 102, each of the body portions 11 is positioned between a pair of preheating drive portions 121 arranged along one direction A And the preheating drive parts 121 are inserted into the insertion groove 11a of the body part 11. [ In addition, the connection portion 12 is positioned between the four preheating drivers 121. As a result, the roller 10 is positioned on the preheating drivers 121. In addition, when the preheating drive unit 121 is rotated about the central axis, the roller 10 can be rotated about the connecting portion 12 as an axis.

The preheating body 123 is positioned above the preheating drive 121. Here, the preheating body part 123 may be positioned to correspond to between the four preheating drive parts 121. When the roller 10 is placed in the preheating drive 121, the preheating body 123 is positioned above the connection 12 of the roller 10. As a result, the preheating body portion 123 can heat the roller 10 by applying heat to the roller 10, particularly, the connecting portion 12. Since the roller 10 is rotated by the preheating drive unit 121, the preheating body 123 can heat the roller 10 uniformly along the circumferential direction in combination with the preheating drive unit 121.

The preheating body 123 of the present embodiment is shown to heat the roller 10 by emitting a flame, but it is not limited thereto and may be various components that can apply heat to the roller 10.

The preheating transfer section 125 is located below the preheating drive section 121 and is moved in the vertical direction. Here, the preheating transfer part 125 may be positioned so as to correspond to between the four preheating drive parts 121. When the roller 10 is placed in the preheating drive 121, the preheat transfer 125 is located below the connection 12 of the roller 10. Here, the upper surface of the preheating transfer part 125 is formed so as to be gradually tilted downward along one direction (that is, toward the welded part 103).

When the heating of the roller 10 is completed, the preheating transfer section 125 moves upward and contacts the roller 10. [ The roller 10 is further moved upward by the preheating transfer unit 125 and is rotated along the upper surface of the preheating transfer unit 125 when it is spaced from the preheating drive unit 121 and positioned above the preheating drive unit 121. As a result, the roller 10 can be transported toward the weld 103.

The welding portion 103 is connected to the preheating portion 102 and is positioned along the one direction A and is supplied with the roller 10 guided from the preheating portion 102. The roller 10 heated by the preheating section 102 is accommodated in the welding section 103 and the welding section 103 rotates the roller 10 about the connecting section 12. At this time, the welding portion 103 welds the roller 10, particularly the connecting portion 12, to the welding roller 10a.

The welding portion 103 includes an induction guide portion 131, a welding housing portion 133, a welding drive portion 135, a welding body portion 137, and a weld transfer portion 139.

The induction guide portion 131 is connected to the preheating drive portion 121 of the preheating portion 102 and is positioned along the one direction A. [ Here, the guide portion 131 may have a shape corresponding to the supply guide portion 101. The roller 10 can be guided from the preheating section 102 to the guiding guide section 131 and conveyed along the guiding guide section 131. [

The induction guide portions 131 are formed as a pair and each have a bar shape. The guide guide portions 131 are positioned along one direction A and are spaced apart from each other in parallel. A part of the guiding part 131 is inserted into the insertion groove 11a of the body part 11 and the connecting part 12 is inserted into the guiding part 131). The roller 10 can be conveyed in the one direction A along the guide guide portion 131 without being separated from the guide portion 131. [

The guide portion 131 may be formed with a concave mounting portion 131a. Here, the mounting portion 131a has a size corresponding to the roller 10. The roller 10 can be inserted along the guide portion 131 and inserted into the mounting portion 131a. As a result, the roller 10 can be positioned on the guiding guide portion 131 in a stopped state.

The welding housing part (133) accommodates the guide guide part (131). An inlet port 103a and an outlet port 103b are formed in the welding housing section 133. The inlet port 103a is formed so as to correspond to the front end of the induction guide section 131 and the outlet port 103b is formed to correspond to the rear end of the induction guide section 131. [

Further, the welding housing portion 133 includes an inlet door 133a and an outlet door 133b. The inlet door 133a is installed in the welding housing part 133 to open and close the inlet 103a and the outlet door 133b is installed in the welding housing part 133 to open and close the outlet 103b.

When the heating of the roller 10 is completed, the inlet door 133a opens the inlet 103a so that the roller 10 can be guided through the inlet 103a into the interior of the welding housing part 133. [ When the welding of the roller 10 is performed, the inlet door 133a closes the inlet port 103a and the outlet door 133b closes the outlet port 103b. As a result, the welding housing part 133 is completely sealed. When the roller 10 is produced by the welding roller 10a, the discharge door 133b opens the discharge port 103b and the welding roller 10a is discharged from the inside of the welding housing part 133 through the discharge port 103b Can be discharged.

The welding drive part 135 is formed as a pair and is positioned so as to correspond to the mounting part 131a inside the welded housing part 133. [ Here, the welding drive unit 135 is symmetrical with respect to the mounting portion 131a. When the roller 10 is inserted into the mounting portion 131, the roller 10 is positioned between the welding drives 135 and the welding drive 135 is positioned facing both longitudinal sides of the roller 10. The welding drive section 135 can contact both longitudinal sides of the roller 10 to rotate the roller 10. [ Here, the roller 10 can be rotated about the connecting portion 12 as an axis.

The welding body portion 137 is positioned above the mounting portion 131a and can be positioned so as to correspond to between the welding drive portions 135. [ The welding body portion 137 is positioned on the upper side of the connecting portion 12 of the roller 10 when the roller 10 is inserted into the mounting portion 131a and positioned between the welding drive portions 135. [ As a result, the welding body portion 137 can weld the roller 10, particularly, the connecting portion 12. Since the roller 10 is rotated by the welding drive section 135, the welding body section 137 can weld the roller 10 evenly along the circumferential direction in combination with the welding drive section 135, (10a).

On the other hand, when the welding body portion 137 welds the roller 10, the inlet port 103a is closed by the inlet door 133a and the outlet port 103b is closed by the discharge door 133b, (133) can be sealed. As a result, the spark due to the welding may not leak to the outside.

The welding transfer portion 139 is located on the bottom surface of the mounting portion 131a and can be positioned so as to correspond to between the welding drive portions 135 and can be moved up and down. When the roller 10 is inserted into the mounting portion 131a and positioned between the welding drive portions 135, the welding transfer portion 139 is positioned below the connecting portion 12 of the roller 10. [ Here, the upper surface of the welded transfer portion 139 is formed so as to be gradually tilted downward along the one direction A (that is, toward the discharge port 103b).

When the roller 10 is generated by the welding roller 10a, the welding drive part 135 is separated from the welding roller 10a. At this time, the welding transfer unit 139 moves upward and contacts the welding roller 10a. The welding roller 10a is further moved upward by the weld transferring section 139 and is rotated along the upper surface of the weld transfer section 139 when being spaced from the mounting section 131a and positioned above the mounting section 131a. Thus, the welding roller 10a can be transported toward the discharge port 103a of the welding housing part 133 and discharged.

The discharge guide portion 104 is connected to the guide portion 131 of the welding portion 103 and is positioned along the one direction A. The welding roller 10a is positioned on the discharge guide portion 104 and the central axis of the welding roller 10a is positioned in the horizontal direction so as to intersect the one direction A. [ The discharge guide portion 104 can transport the welding roller 10a along the one direction A. [ The welding roller 10a may be conveyed along the discharge guide portion 104 and guided to the collecting portion 200. [

The discharge guide portions 104 are formed as a pair and each have a bar shape. These discharge guide portions 104 are respectively connected to the induction guide portion 131 and located along one direction A, and are spaced apart from each other in parallel.
