Description

Wire Rod Unloading Lifter

The present invention relates to a device for safely lifting a commercialized wire rod and safely unloading it on a truck, and more specifically, handling defects due to the rolling movement of the product during unloading, that is, ring kinking, scratches caused by poor gaps, and rolling. When unloading, the direction of the unloaded product is changed so that it is impossible to unload by colliding with the unloaded product first, and the acceleration due to rolling movement occurs when unloading the slope of the facility, and it prevents the straps from bursting or being damaged by the elasticity caused by the impact of the stopper. It relates to a wire coil unloading lifter device having a function to unload a product without using a lifter.

In general, looking at the process of manufacturing the wire coil, as shown in Figure 1, when the iron wire (2) loaded through the rolling roll (1) passes through the laying head (3), the spiral wound wire (4) If this is integrated into the reform tube 5, the wires that have been scattered and moved for a long time become a wire rod coil (hereinafter, referred to as a coil) 20 having a lump form.

In the mandrel 6 which is rotated by a drive motor not shown, the integrated coil 20 is transferred from the mandrel 6 to the outside by using a C-HOOK 7 and transferred. It inspects with the magnifying glass 8, and removes a defect part with the cutter 9, and simultaneously collects a specimen. Subsequently, after the packing process of compressing the coil 20 as a crimping mechanism 10 and binding the band 20 to a band, the coil product is completed by attaching a label tag 12 that is weighed as a scale 11 and recorded various information. After the commercialization of the coil 20 is transferred to the cradle 31 of the coil unloader 30 as a sea hook (7), and then unloaded as a coil unloader (30) to be put in a warehouse and shipped. .

The conventional method of unloading the coil 20 as the coil unloader 30 is, as shown in FIG. 2, when the sea hook 7 carrying the coil 20 arrives at the coil unloader 30, the cradle. When the cradle 31 is lifted and the coil 20 and the seed hook 7 are separated from each other due to the lifting operation of the cylinder 31a mounted on the lower surface of the 31, the seed from the coil 20 When the hook 7 is pulled out and the lifted cradle 30 is inclined to one side by the cylinder 31a, the cylindrical coil 20 begins to roll by its own weight, and the coil 20 which begins to roll is loaded with a bogie ( By the tilting table 33 until it reaches 34, it continues to reach the trolley 34, which is stopped by the stopper 35 installed so that the rolling movement does not deviate from the trolley 34. When the three coils 20 are sequentially loaded on the trolley 34, the three coils 20 are fabricated using the sea hook 37 of the ceiling crane 36 as shown in FIG. It will be rolled up at the same time and received in the warehouse.

However, as shown in Figs. 2 and 3, due to the functional characteristics of the facility when unloading the coil 20 transferred as the sea hook (7) on the trolley 34 as a conventional coil unloader (30) Since the coil 20 is rolled and unloaded, as shown in FIG. 4 (a), the ring 20 protrudes to the outside of the coil 20 in contact with the tilting table 33 during rolling movement. 22 is generated, and when the coil 20 reaches the bogie 34, it is rolled up with acceleration, so that the coil 20 of the coil 20 is installed on the stopper 35 installed to secure a stable position on the bogie 34. As shown in FIG. 4 (b), the band 24, which is bound due to the impact, may frequently be damaged, as well as the surface of the coil 20 whose rolling direction is changed during the unloading operation. First, the collision with the coil 20 unloaded to the trolley | bogie 34 caused the problem which made unloading work difficult.

As shown in FIG. 3, when the three coils 20 are loaded onto the trolley 34 to be stored in the warehouse with the ceiling cranes 36, the coils of the coils 20 are irregularly formed. Since it is difficult to accurately control the spacing between the first and the first loaded coil 20 and the rolling coil 20 is brought into contact with the severe friction scratches 23 on both ends of the coil 20. In addition, the label tag 12 that records and attaches the coil product information during the contacting process may cause damage, contamination, or dropping, thereby making it difficult to identify the coil.

Therefore, the present invention has been devised to solve the conventional problems as described above, the purpose of which can be loaded on the trolley without rolling the coil on the cradle to prevent damage to the coil products, to prevent collision between products unloading operation This is to provide a wire rod unloading lifter device that can be smooth, warehouse automation.

Referring to the operation and effects of the wire rod unloading lifter device having the configuration as described above are as follows.

As shown in FIGS. 9 and 10, the wire coil unloading lifter device 100 according to the present invention is installed on one side between the trolley 34 and the cradle 31, which is a conventional coil unloader 30, and a coil. When the sea hook 7 carrying 20 arrives at the cradle 31, the cradle 31 is lifted by the cylinder 31 a so that the coil 20 at the upper portion is raised to the sea hook 7. The inner diameter part is separated from In this state, as soon as the release of the seed hook 7 is completed, a limit switch (not shown) for detecting the release of the seed hook 7 is driven by a signal, and the driving motor 71 is operated to be transmitted therefrom. When the reduced power is decelerated by the reduction gear 72 at an appropriate rotation ratio and the reduced power is transmitted to the driven sprocket 75 through the driving sprocket 73 and the chain member 74, the rotation shaft 53 is supported by the arm support 62. ) Is assembled so as to be rotatable, and the arm 51 waiting in the vertical state is rotated 90 ° toward the cradle 31 supporting the coil 20 so that the upper hanger 41 is in the coil 20. It stops when it is located in the center of the neck.

The stop of the arm 51 is detected by a detection signal generated while the detection bar 88 of the fixed ring 86 assembled to the rotation shaft 53 is detected by the fourth sensor member 84 disposed at the 0 ° position. This is achieved by stopping the drive of the drive motor 71.

When the arm 51 for swinging the coil 20 is turned 90 °, the hanger 41 at the upper end thereof is retracted by the operation cylinder 42 so as not to interfere with the coil 20 so that the second sensor member ( The operation cylinder 42 is inflated by the detection signal of the fourth sensor member 84 confirming that the arm 51 is rotated 90 degrees toward the cradle 31 in the initial state detected by 82.

By retracting the actuating cylinder 42 by the detection signal of 85, the hanger 41 is retracted to the rear and drawn out from the inner diameter of the coil 20, and the withdrawal completion of the hanger 41 is completed. It is confirmed by the second sensor member 82 for sensing.

In addition, the reverse operation of the operation cylinder 42 is stopped by the monitoring signal of the second sensor member 82, and the driving motor 71 is stopped again to operate the arm 51 in the opposite direction. Since the arm 51 rotates forward, the arm 51 is rotated again to the cradle 31 in order to reenter the cradle 31 and move the coil 20 waiting to move, wherein the arm 51 is rotated. The size of the rotation of the arm 51 is rotated by only 90 ° so that the arm 51 can stand in a vertical position until the sea hook 7, which is waiting in the cradle 31, is released. Is stopped by the stop driving of the drive motor 71 by a detection signal generated when the detection bar 88 installed on the fixing ring 86 is detected by the third sensor member 83 disposed at 90 °. 90 ° forward rotation, 180 ° reverse rotation and 90 ° forward rotation of these arms 51 One cycle, that is, once one operation is completed, as one coil 20 is transferred to the trolley 34, the same operation is repeated to continuously roll the coil 20 mounted on the cradle 31. It can be safely transported onto the trolley 34.

As mentioned in the above configuration in the coil transfer process, the hanger 41 is loaded by the weight of the coil given to the hanger 41 by the hanger holder 52 and the hanger support 44 when the coil 20 is walked and transferred. It can support enough, and reduce excessive force. And, the guide wheel 43 of the hanger support 44 is located on the guide flaw 45 on both sides of the hanger 41 to facilitate the forward and backward operation of the hanger 41 and at the same time the hanger 41 It will also play a role.

When the three coils 20 are placed on the trolley 34 by the repeated rotation operation of the arm 51, the three coils 20 are wound up by the three hooks 37 of the ceiling crane 36 in the same manner as in the prior art, and are then stored in the warehouse. Will be relocated.

According to the present invention as described above, when the plurality of coils 20 are unloaded on the trolley 34 and are simultaneously transported, the arm 20 is pivoted without rolling the coils 20 on the tilting table 33. Since the coil 20 can be lifted from the cradle 31 and unloaded on the trolley 34 as the hanger 41 mounted on the top, various handling defects generated by rolling movements, that is, ring bending ( 22), the friction flaw 23 generated by the contact between the standby coil 20 and the coil 20 being unloaded, the unloading due to the collision of the unloaded coil 20, the impact of the stopper 35 It can prevent the crimping | compression-bonding which arises, the burst of the band 24, etc.

Therefore, when various handling defects occur in the coil 20, by unwinding the coil 20, which is already bound and packaged so as not to be delivered to the demand, post-processing and removing some defective parts, and then eliminating the double-packing, The amount of binding material used can be reduced, the error rate can be improved, and the safety and work efficiency can be significantly improved compared to the conventional one. In addition, the effect of preventing damage and contamination of the label tag 12 to easily identify various types of coil information is obtained.
