Fig. 7 is a view showing part A of Fig. FIG. 8 is a block diagram illustrating a process of driving a stepping motor in a conveyor constructed in a sleeve automatic insert system according to the present invention.

A winding machine 110 for winding a hot or cold-worked steel sheet round is constituted by a body 113 in which a driving device is accommodated and a rotary shaft 115 protruding from one side of the body 113 and winding the steel sheet is protruded . Therefore, the steel sheet fed to the rotating shaft 115 is rolled into a coil shape and shipped. At this time, the rotation shaft 115 is inserted into the pipe-shaped sleeve S made of paper, so that the steel sheet is wound on the outer surface of the sleeve S. Therefore, it is prevented that the steel plate is wrinkled in a state of being wound in a concentric shape.

The sleeve automatic insertion system 100 according to the present invention is characterized in that the rotating shaft 115 of the winding machine 110 is automatically inserted into the sleeve S. [

To this end, the present invention is configured as follows.

3 and 4, a conveyor 120 disposed at the side of the winding machine 110 and configured to supply the sleeve S is constructed and disposed between the conveyor 120 and the winding machine 110 The robot arm 130 is configured to pick up the sleeve S and transfer it to the rotation shaft 115 to operate to insert the rotation shaft 115. The robot arm 130 includes a finger 133 that can grip and release the sleeve, so that any person skilled in the art can understand the detailed description.

3 to 5, the conveyor 120 includes a side plate 121 configured to guide the sleeve S to left and right sides. The conveyor 120 is connected to the front end of the side plate 121 on both sides, And a conveyance plate 125 is disposed on the left and right sides of the inside of the front support plate 124 and fixed with a nut 128 through which the nut 124 is fixed.

The screw shaft T is rotatably supported by the front support plates 124 on both sides and is configured to be fastened to the nuts 128 on both sides. The step motor M is fixed to the screw shaft T and fixed to the outer surface of the one side front support plate 124. The step motor M is fixed to the front support plate 124 on both sides, 125 are formed.

The screw shaft T is divided into a left screw and a right screw, respectively, and fastened to the respective nuts 128. Therefore, when the screw shaft T rotates in the forward and reverse directions by the step motor M, the conveying plate 125 is configured to be opened and closed.

Referring to a more specific configuration of the conveyor 120, a leg 123 configured to be arranged toward the robot arm 130 and configured to be supported on a floor surface for a supporting function is constructed. The legs 123 are configured to be lower toward the front (robot arm side).

A bottom plate 122 supported by the legs 123 and inclined downward toward the robot arm 130 and formed only up to the side plate 121 is formed. Since the bottom plate 122 is supported by the leg 123 configured to be lower toward the front, it is naturally inclined downward toward the front.

A bar B is fixed to the upper surface of the bottom plate 122 so as to extend to the feeding plate 125 and is opposed to the bar plate B, B) is configured to be rotatable. The roller (L) protrudes upward of the bar (B) so that it can support the sleeve (S). A plurality of sets of the bar (B) and the roller (L) are arranged laterally so as to easily support the long sleeve (S). The set consisting of the bar (B) and the roller (L) is arranged between the two side transfer plates (125). The guide shaft G can pass through the screw shaft T and the guide shaft G so that the sleeve S can be guided through the front support plates 124.

The side plate 121 is configured to be fixed to both side surfaces of the bottom plate 122 and to guide the sleeve S in the longitudinal direction of the bottom plate 122.

6, since the sleeve S is hingedly connected to the rear end portion V of the front support plate 124 and extends rearward to abut the inner surface of the side plate 121, the sleeve S is guided between the front side support plates 124 A guide plate 160 is formed. Therefore, even if the front support plate 124 is narrowed or widened, the guide plate 160 rotates so that the end portion (the end portion on the opposite side of the hinge-connected side) can contact the inner surface of the side plate 121.

7, a weight sensor 126 mounted at a rear portion of the conveyor 120, that is, at a position where the sleeve S is initially seated, for sensing the weight of the sleeve S is constructed. The weight sensor 126 is configured to be supported by the bottom plate 122 as a load cell and to transmit the weight of the sleeve S as data. An air cylinder 127 is mounted on the conveyor 120 so as to be disposed behind the weight sensor 126 and configured to push the sleeve S seated on the weight sensor 126 forward.

8, the weight data of the sleeve S is received from the weight sensor 126 and the length of the sleeve S is recognized through the weight data. Thereafter, the step motor M is driven, The controller C is programmed to adjust the width of the transfer plate 125 and then drive the air cylinder 127 to push the sleeve S. [

Since the sleeve S has various lengths, the sleeve S corresponding to each length has an inherent weight. Therefore, since the length of the sleeve S corresponding to each weight is stored in the control unit C, the control unit C can receive the weight data and recognize the length of the sleeve S immediately. The stepping motor M is operated so as to spread with a width corresponding to the length of the sleeve S in a state in which the transfer plate 125 is completely in close contact.

Further, when a plurality of the winding machines 110 are provided, the robot arm 130 is configured in each of the winding machines 110. The rails 140 are arranged from the upper portion of the conveyor 120 to the upper portion of the robot arm 130 so that the sleeve S can be supplied to the robot arm 130 remote from the conveyor 120.

The rail 140 is fixed to a support 150 supported on the bottom surface of the rail 140. The conveyor 143 is mounted on the rail 140 and can be spontaneously conveyed. A stepping motor is mounted on the conveying device 143 so as to be movable forward and backward along the rail 140. In addition, the conveying device 143 is configured to have a stiffness 147, and a step motor is installed to unroll and wind the rope 149. And the rope 149 is provided with a finger 145 capable of holding the sleeve S therein. The fingers 145 are configured such that the air cylinders are mounted and are able to pick up and release the sleeve S spontaneously.

Hereinafter, an operation example of the sleeve automatic insert system 100 according to the present invention will be described.

First, the sleeve S is placed on the weight sensor 126, as shown in Fig. 7, with the width of the front support plate 124 not matching the length of the sleeve S. [ Then, the control unit C receives the weight of the sleeve S, recognizes the length corresponding to the sleeve S, and then drives the step motor M. At this time, the step motor M is driven so that the front support plates 124 on both sides come into close contact with each other. In this state, the front support plate 124 is opened so as to accommodate the length of the sleeve S. At this time, a width of +5 mm to +10 mm of the length is suitable.

When the front support plate 124 is opened, the operator rotates the guide plate 160 so that the rear end portion is brought into close contact with the inner surface of the side plate 121.

In this state, the control unit C actuates the air cylinder 127 so that the rod is elevated to push the sleeve S out. Then, the sleeve S rolls forward along the inclined bottom plate 122. At this time, the roller (L) smoothly rolls the sleeve (S). And is received between the front support plates 124 through the guide plates 160 on both sides.

Then, the robot arm 130 is operated, and the fingers 133 pick up the sleeve S and transfer it to the winding machine 110. After the rotation shaft 115 of the winding machine 110 is inserted into the sleeve S, the sleeve S is placed and the finger 133 returns to the original position.

Then, since the steel sheet is supplied to the rotating shaft 115, the steel sheet can be wound concentrically around the sleeve S.

In the case of the winding machine 110 located far away from the conveyor 120, the conveying device 143 allows the rail 140 to be conveyed to the top of the front support plate 124 by self-power. After the robber 147 is operated to lower the rope 149, the fingers 145 hold the sleeve S and operate the robber 147 to wind up the rope 149. Then, the conveying device 143 is moved along the rail 140 to the winding machine 110. Then, the stabilizer 147 is operated to loosen the rope 149. The robot arm 130 grips the sleeve S gripped by the finger 145 and the finger 145 puts the sleeve S. [ Then, the stabilizer 147 is operated to wind up the rope 149, and then the conveying device 143 is returned to the original position by raising the rail 140 again. The robot arm 130 supplied with the sleeve S transfers the sleeve S to the rotary shaft 115 of the winding machine 110 and inserts the rotary shaft 115 into the sleeve S. [

According to the present invention as described above, it is possible to automatically feed the sleeve S and to insert the rotary shaft 115 without depending on the work of the operator. Further, since the width of the front support plate 124 can be smoothly adjusted to the sleeves S having various lengths, one conveyor 120 can be applied to the sleeves S of all lengths. Therefore, it is not necessary to provide the conveyor 120 for each length of the sleeve S. As a result, the productivity can be improved and the production cost can be lowered due to the reduction of labor costs.
