Bulk bag opening device with swing unit

Abstract

Proposed is a bulk bag opening device including a transfer unit that transfers a bulk bag, a cutting unit that cuts the transferred bulk bag, and a discharge unit that discharges contents to a hopper. The bulk bag opening device includes a swing unit having a length adjustment means provided outside the bulk bag to be spaced apart therefrom by a predetermined distance and accessing to the bulk bag, and a grip means provided on an end of the length adjustment means to grip the bulk bag, thereby shaking and emptying the contents remaining in the bulk bag.

What is claimed is: 
     
         1 . A bulk bag opening device with a swing unit, the device comprising a transfer unit that transfers a bulk bag, a cutting unit that cuts the transferred bulk bag, and a discharge unit that discharges contents to a hopper,
 wherein the bulk bag opening device comprises:   a swing unit comprising length adjustment means provided outside the bulk bag to be spaced apart therefrom by a predetermined distance and accessing to the bulk bag, and grip means provided on an end of the length adjustment means to grip the bulk bag, thereby shaking and emptying the contents remaining in the bulk bag.   
     
     
         2 . The bulk bag opening device of  claim 1 , wherein the swing unit is equipped with a vibrator. 
     
     
         3 . The bulk bag opening device of  claim 1 , wherein the length adjustment means is an actuator operated by a cylinder or a motor. 
     
     
         4 . The bulk bag opening device of  claim 1 , wherein the swing unit comprises moving means connected to the length adjustment means to be movable along a side of the bulk bag. 
     
     
         5 . The bulk bag opening device of  claim 1 , wherein the cutting unit comprises blades arranged in four directions from a center so that diagonal lines of a lower surface of the bulk bag moving downward are cut across each other. 
     
     
         6 . The bulk bag opening device of  claim 1 , wherein the transfer unit moves the bulk bag down to seat the bulk bag on an upper portion of the hopper of the discharge unit, the cutting unit cuts the bulk bag, and then a lifting speed is adjusted by the transfer unit so that the contents in the bulk bag naturally flow and are transferred to the hopper, thus minimizing dust generation, and the swing unit grips and swings the bulk bag lifted to a certain height.
