Even if not illustrated in the description of the present invention, technical content that can be easily derived by a technician of the relevant technology through variance, design change, substitution, etc. based on the present application in order to improve the performance of the container surface polishing apparatus 100 It would be natural to fall within the scope of the rights of

Looking at the state of use of the container surface polishing apparatus 100 to which the technology of the present invention is applied as described above is as follows.

First, when the container 104 is mounted on the container 116 of the container mounting part 110, a vacuum force is generated by the operation of the vacuum means connected to the container 116 so that the container 104 is vacuum-adsorbed and not moved. Is done.

The adhesion pad 117 interposed on the upper part of the mounting body 118 is in close contact with the container 104 to eliminate the fear of vacuum leakage, and the mounting pipe 121 connected to the vacuum hole 120 formed in the mounting body 118 Since it is connected to the vacuum means through the container 104 is held firmly until the vacuum is released.

Of course, if the container 104 is not aligned in a straight line with respect to the moving direction by using the left and right adjusters 124 and 125 of the container splitter 119 protruding to one side of the mounting body 118, maintain a straight line. It would be natural to avoid being biased in either direction left or right.

In this state, when the moving cylinder 114 advances the moving plate 1123 to move the mounting device 116 to which the container 104 is mounted, the side polishing parts 130 installed on both sides of the frame 105 are It is operated to polish both sides of the container 104, and the top surface of the container 104 is polished while passing through the side polishing part 130 and passing the top polishing part 150 with the continuous advance of the moving plate 123.

Of course, the moving cylinder 114 may return to its original position after passing through the upper surface polishing part 150, and may be repeatedly polished several times depending on the type of container 104, and the surface polishing apparatus of the present invention It would be okay to arrange (100) in series or in parallel to perform continuous polishing.

In the case of the mounting device 116 installed on the upper surface of the movable plate 112, the height of the movable plate 112 can be adjusted in the up and down directions corresponding to the type of the container 104 to be polished. Since the mounting pipe 121 connected to the lower side of the mounting body 118 is coupled to the mounting hole 122 formed in the moving plate 112 and is intercepted by the adjusting screw, loosen the adjusting screw and tighten the mounting pipe 121 ) It is possible to adjust by moving the moving plate 112 in the up and down directions.

Looking at the process of polishing both sides of the container 104 by the side polishing part 130 and the top polishing part 150, when the container 104 is moved by the container mounting part 110, the brush motor 140 It is operated to rotate the brush wheel 142, and since the container 104 passes between the brush wheels 142, both sides of the container 104 are polished by the rotating brush wheel 142.

In the case of the side polishing part 130, it is possible to freely adjust the height and angle corresponding to the type of the container 104 and use it as follows.

Fixing the vertical body 132 connected to the bracket 131 fixed to the frame 105, the horizontal body 133 connected to the vertical body 132 and the brush housing 134 connected to the horizontal body 133 It is connected by means, and since the fixing hole is in the form of a long hole or an arc, it is possible to adjust the movement in the vertical direction, the movement in the horizontal direction, and the angle by loosening and tightening the fixing means. It becomes possible to respond.

And, the brush housing 134 and the horizontal body 133 are connected by a hinge 135 so that when the container 104 moves forward, it rotates in the forward direction, and when the container 104 moves backward, it rotates in the backward direction to brush the surface of the container 104 It is possible to prevent the wheel 142 from digging into a lot.

The brush housing 134 is able to return to its original position while moving in the forward and backward directions of the container 104 by fixing the tension control bar 136 to the horizontal body 133 and this tension control bar 136 Since both sides of the brush housing 134 and the tension control means 137 are connected to each other, the brush housing 134 is moved forward and backward by the hinge 135 and then returns to its original position.

And after passing through the side polishing part 130, the Youngna motor 157 of the upper polishing part 150 operates to rotate the polishing brush 155, and in the process of passing through the upper polishing part 150, the container 104 The upper surface of the is to be polished.

In particular, in the case of the upper surface polishing part 150, it always descends downwards due to its own weight, but when the container 104 passes as it is in this state, the amount of polishing increases, so both sides of the upper surface polishing frame 152 The rising damper 160 installed on the container 104 lifts the upper polishing frame 152 upward when entering the container 104, so that the surface can be properly polished.

That is, the spring 167 interposed on the damping rod 161 constituting the rising damper 160 is supported by the spring settable 168, and when the spring 167 is relaxed, the upper surface polishing frame surface 2) descends. In this state, when the spring 167 is compressed to increase the anti-reaction force, the upper surface polishing frame 152 is lifted upward.

Therefore, in the case of increasing the amount of polishing on the upper surface of the container 104, the spring settable 168 is lowered to relax the spring 167 to lower the upper surface polishing frame 152 so that the polishing brush 155 becomes the container 104 ), and if you want to reduce the amount of polishing on the upper surface of the container 104, raise the spring bandage 168 to compress the spring 168 and raise the upper polishing frame 152 for polishing. Adjustment is possible by making the brush 155 touch less on the surface of the container 104.

Although it is possible to adjust the amount of polishing, it is possible to use the upper surface polishing frame 152 by adjusting the height of the upper surface polishing frame 152 using the rising damper 160 in response to the height (or thickness) of the supplied container 104.

The container mounting part 110, the side polishing part 130, and the upper surface polishing part 150 are electrically controlled so that they can be moved clearly by a controller that is approved for detection such as a sensor and a timer (not shown). What is achieved is well known, so a detailed description is omitted.

The present invention as described above improves polishing efficiency and enables comfortable and safe work while maintaining uniform quality by mechanically polishing the surface of a container in a shape such as a square, which cannot be polished by simple rotation, such as a circle or a cylinder. While maximizing productivity.
