Figure 3b is a state of damage occurrence of the bearing (69), Figure 3b is a state of lubricating oil supply failure of the conveyor belt of the conventional conveyor portion, Figure 3c is a state of damage occurrence of the roller chain conveyor 70 of the conventional conveyor portion, Figure 3d Is a partially enlarged perspective view of the chain 76 of the roller chain conveyor of the conventional conveyor part, and FIG. 3E is a perspective view of the tension reinforcement apparatus 95 of the roller chain conveyor of the conventional conveyor part.

2a and 2b, the conveyor unit 90 for transferring the conventional wire coil 71 is composed of a conveyor belt 60 and a roller chain conveyor (70).

Looking at the configuration of the conveyor unit 90 briefly, the conveyor belt 60 of the conveyor unit 90 is a sprocket (62) rotated in one motor 73 and the reduction gear 74 and this It is composed of a conveyance belt 61 is engaged and rotated.

In addition, the side of the sprocket 62 is mounted with a first chain gear 64 connected to the central axis 62a of the sprocket 62 and wound with a chain 66, the central axis bearing Supported by (63), the chain 76 is rotated in engagement with the first chain gear 64 and the second chain gear 65 spaced apart. In addition, the gear 65a coaxially spaced apart from the second chain gear 65 rotates in engagement with the chain 76 provided on the side of the roller chain conveyor 70.

The roller chain conveyor 70 includes a plurality of rollers 72 installed in contact with the chain 76 and the inner side of the chain 76 and supported to transport the wire coil 71.

When the motor 73 is rotated by the above-described configuration, the kenveyor belt 60 and the roller chain conveyor 70 are simultaneously rotated by chain driving and gear coupling.

In this case, referring to FIG. 1, the large diameter wire coil 71, which is generally rolled in a hot state, is wound alternately in two reelers 91, and then transported horizontally onto the conveyor belt 60. It is placed on the conveyance belt 61.

Subsequently, the wire coil 71 placed on the conveyor belt 60 undergoes a pattern process that is cooled differently according to the material, and then the conveyor at a constant speed for inspection and product quality at the back end of the product after cutting and packaging process. On the conveyance belt 61 of the belt 60 is conveyed, and then caught on the hanger 75 is conveyed to the subsequent process.

However, when the end portion 71a of the wire rod coil 71 is not easily wound in the drum of the winding machine reeler 91 during the process of transferring the wire coil 71 using the conveyor belt 60, The wire coil 71 has a phenomenon that the end portion 61 of the wire belt 71 is further released due to the acceleration of the transfer belt 61 while driving on the conveyor belt 60, and thus the wire coil 71 ), A winding defective portion 71b is generated at the lower end of the.

In addition, referring to Figures 2a and 2b, the wire coil 71 is moved from the conveyor belt 60 to the roller chain conveyor 70, the wire rod is poor winding while running on the roller chain conveyor (70). The end portion 71a of the coil 71 is sandwiched between the rollers 72, so that the chain 76 bounces as shown in FIG. 3C, thereby causing the rollers ( 72 directly hits the lower portion of the wire coil 71 to damage the lower portion of the wire coil 71, or the chain 76 constitutes the chain 76 due to the force that the chain 76 bounces. Small roller pins 76a are broken and cracks 76b are generated in the chain 76, so that the transfer operation is interrupted as a whole.

In addition, a tension reinforcing device (95) consisting of a support roller (96) installed at the end of the connecting table (97) fixed to the support (98) by a bolt (99) is installed on the lower inner surface of the chain (76). While the running tension of 76 is kept constant, the tension reinforcing device 95 only maintains the tension of the chain 76 in a fixed fixed setting position, so that the chain 76 is used for a long time. If the tension is increased, there is a problem that can not give tension to the elongated chain 76, the end portion 71a of the wire coil 71 is sandwiched between the rollers 72, the chain 76 bounces There is a problem in that it is not possible to impart proper tension to the chain 76 even when the chain 76 is prevented from deviating from the existing travel space.

In addition, referring to Figures 3a and 3b, the conventional conveyor belt 60, the central shaft (68a) for supporting the rollers 68 and the rolling bearing 69 in the conveying belt 61 is bent due to overloading In addition, the rolling bearing 69 is broken, and as a result, the rollers 68 falling out have a problem of acting as a stopper that prevents the movement of the conveyance belt 61.

In order to solve this problem, it is necessary to continuously supply lubricating oil to the rolling bearing 69 in the conveyance belt 61. Conventionally, the tip of the grease supply device 67 disposed on the rollers 68 side is transferred to the rollers. Nipples (not shown) arranged on the side of 68 were supplied with grease, which is a lubricant while being touched, and the viscosity of the grease was high so that the grease was not properly supplied to the rolling bearing 69, and then lumped to the bottom 67a. There is a problem that the lubrication supply process is not performed smoothly as a whole fall into the) form.

The present invention has been proposed in order to solve the above-mentioned conventional problems, when the conveyor belt and the roller chain conveyor device of the conveyor for conveying the large diameter wire coils are overloaded, a phenomenon that the chain of the roller chain conveyor bounces.

First, when the chain 76 is momentarily bounced off or out of the roller chain conveyor 70 of the conveyor unit 90 to the upper portion of the roller 72 driving gear 65a, the chain Although the rollers 72 collide against the lower portion of the buffer rail 11 installed at an upper portion with a slight height distance from the 76, an impact force is applied to the rubber property of the buffer rail 11. As a result, the buffer rail 11 is dispersed and absorbed into the entire buffer rail 11. In addition, the second buffer spring 14 directly installed on the upper portion of the buffer rail 11 also absorbs the impact applied to the lower portion of the buffer rail 11 by its elastic force, so that the roller 72 and the parts connected thereto are Allow for cushioning to prevent breakage.

On the other hand, the first buffer spring 14 serves to adjust the elasticity of the second buffer spring 13, by turning the support rod 15 to the support end (15a) the first buffer spring ( 14) by adjusting the degree of pressing, since the elastic force of the first and second buffer springs 13 and 14 can be adjusted according to the impact received by the shock absorbing rail 11, the chain 76 springs up when an impact occurs. It is possible to control the degree of the rising height, so that the chain 76 does not deviate to the surroundings and serves to slide well along the driving path so that the cracks or cuts in the chain 76 do not occur.

On the other hand, the wheel 21 of the tension adjusting unit 20 acts as a flow wheel, and does not maintain the tension of the chain 76 at a constant position as in the conventional tension reinforcement device 95, the When the chain 76 is stretched or sag due to springing during use, the operation bar 28a of the hydraulic cylinder 28 is in the A direction (Fig. 6A) by its hydraulic force and the elastic force of the spring 29. And tension is applied while the wheel 21 is tightly coupled to the inner surface of the chain 76 so that the chain 76 always has a tension.

On the contrary, when the chain 76 contracts, the operation bar 28a of the cylinder 28 contracts in the B direction (see FIG. 6A) by the hydraulic force and the elastic force of the spring 29. While the wheel 21 is not in close contact with the chain 76, only the appropriate tension is applied to the chain 76.

On the other hand, Figures 8a and 8b is a layout and operation diagram of each of the lubricant supply unit 30 of the damage prevention device 100 according to the present invention.

8A and 8B, the feeding holes 31 of the lubricating oil supply unit 30 are normally connected to the supply shaft 32 so that the nozzle holes 31a are discharged from the discharge holes 32a. And the rollers 68 mounted on the conveyance belt 61 are moved while hitting the lower flat contact surface 31b of the feed cams 31 in order. 31 is rotated by an angle θ, and thus, when the feed cams 31 are rotated to a preset rotational position, the discharge holes 32a and the nozzle holes 31a are arranged to fit together. Lubricant is supplied to the rollers 68 through the outlets 32a and the nozzle holes 31a.

The lubricating oil is supplied only when the rollers 68 respectively rotate the feed cams 31 by an angle θ so that the discharge holes 32a and the nozzle holes 31a correspond to each other. In addition, since the feed cams 31 are returned to their original positions according to the eccentric weight, the discharge holes 32a and the nozzle holes 31a are not disposed to match, and thus the supply of lubricant oil is stopped. Accordingly, the rollers 68 may be supplied with only the necessary portion of the lubricating oil, thereby preventing the waste of excessive lubricating oil supply.

According to the action of the breakage prevention device 100 according to the present invention as described above, even when an overload is transmitted to the conveyor unit 90, the breakage phenomenon due to the phenomenon of the whole splashing is prevented in advance, and the lubricating oil is conveyed to the conveyor belt 60. Is supplied smoothly to extend the life of the conveyor belt 60.

As described above, according to the breakage preventing device for conveying the wire rod coil according to the present invention, even if the conveyance of the roller chain conveyor constituting the conveyor part bounces when the overload is transmitted to the conveyor, the shock is alleviated. Since the chain is not easily separated from the driving mirror, it is possible to maintain a constant tension at all times, so there is a useful effect that the occurrence of damages and breakages is greatly reduced as a whole.

In addition, according to the breakage prevention device of the wire transfer coil conveying unit according to the present invention, since the lubricant is smoothly supplied to the conveyor belt of the conveyor unit, the conveyor belt is not easily worn even if used for a long time, its life is extended, the necessary part Lubricant is supplied only to have a useful effect of preventing the waste of lubricant supply.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
