First, referring to FIG. 2, the structure of the housing seating means 110 will be described as follows.                     

A first workbench 111 is installed on the base rail R1 so as to rotate about a shaft S1 and guide rails 111a are formed on both sides of a lower portion of the first workbench 111. [

The first work table 111 is configured such that a center portion of the uppermost surface of the first work table 111 is open and a first upper plate 114 described later is pushed to the opened position, (114).

A first slider 112 is coupled to the guide rail 111a of the first work table 111 so as to be movable by a cylinder C1 and a ring gear G, And a circular plate 113 is provided rotatably by a gear W.

A first upper plate 114 is positioned above the circular plate 113 and is configured to be raised and lowered above the first work table 111 by a cylinder C2.

A first arm 115 is fixed to both ends of the axis S1 of the first work table 111 and a first swing cylinder 116 is fixed to both ends of the first arm 115 to rotate the first arm 115 by 90 degrees .

Therefore, the housing H placed on the first upper plate 114 is moved in the horizontal direction by the lateral movement of the first slider 112, by the lifting and lowering operation of the cylinder C, and by the motor M, the worm gear W, And its position and direction can be freely adjusted by the ring gear G. [

The second workbench 111 'is mounted on the base rail R1 so that the second workbench 111' is pivoted about the axis S2. The second workbench 111 'includes a base rail R1 (see FIG. 1) R1, and guide rails 111'a are formed on both sides of the lower portion of the second work table 111 '.

A second slider 112 'is movably installed on the guide rail 111'a of the second work table 111' by a cylinder C3 and a cylinder (not shown) is provided on the second slider 112 ' And a second upper plate 114 ', which is raised and lowered upward, is fixed to the cylinder C4. Here, P2 is a guide pin P2 for guiding the movement of the second upper plate 114 '.

A second arm 115 'is fixed to both ends of the axis S2 of the second work table 111' and a second arm 115 'is fixed to both ends of the second arm 115' so as to rotate the second arm 115 ' And a second swing cylinder 116 'is provided at an end thereof.

Hereinafter, the structure of the bearing extracting means 150 of the present invention will be described with reference to FIG.

A push cylinder 121 and a cylinder C are fixed to the ascending and descending plate 141. A support 122 is fixed to the lower portion of the push cylinder 121. In the support 122, (123). Here, P3 is a guide pin for guiding the movement of the lifting plate 141.

An extraction arm 124 is installed at the upper end of the rod cylinder 123 to selectively open the lower portion by the rod cylinder 123.

When the push cylinder 121 descends downward and the extraction arm 124 is inserted into the housing H, the rod cylinder 123 operates to open the lower portion of the extraction arm 124. At this time, the extraction arm 124 And the push cylinder 121 is actuated again to pull up the extraction arm 124 upward. At the same time, the push cylinder 121 is operated again to pull the extraction arm 124 upward.                     

Referring to FIGS. 1 and 3, the configuration of the moving means of the present invention will be described as follows.

A structure wheel 161 is installed at four corners of a bottom surface of the structure 120 so as to be coupled to the foundation rail R1 and a motor M1 is installed on one side of the structure 120, And the motor M1 are connected by a chain 162. Accordingly, when the chain 162 is rotated by the operation of the motor M1, the structure wheel 161 connected to the chain 162 is configured to move the structure 120 while rotating.

A first moving plate wheel 163 is installed at a bottom corner of the first moving plate 130 so as to be coupled to the guide rail R2 and a motor M2 is mounted on one side of the first moving plate 130 A small gear 164 is fixed to an end of the motor M2 and a rack 165 is formed in a lateral direction on one side of the upper surface of the structure 120 so as to be engaged with the small gear 164. Therefore, when the motor M2 is operated to rotate the small gear 164, the first moving plate 130 is moved along the guide rail R2 because the small gear 164 and the rack 165 engage with each other. do.

A second moving plate wheel 166 is installed at a bottom corner of the second moving plate 140 so as to be coupled to the guide rail R3 and a worm gear 167 is mounted on a side surface of the second moving plate 140, And a motor 168 for rotating the worm gear 167 is installed on the worm gear 167. [ Accordingly, when the motor 168 is operated to rotate the worm gear 167, the second moving plate 140 meshed with the worm gear 167 is configured to be pulled or pushed in the direction of the arrow.

On the other hand, in order to move the bearing B extracted by the bearing extracting means 150 to the washing field, a cleaning sheet moving carriage (not shown) is provided at the rear of the structure 120, So that the extracted bearing B is dropped.

To this end, the present invention provides an auxiliary guide rail R4 which is selectively extended to the rear of the structure 120 by a cylinder C5 on the upper part of the structure 120, So that the plate 130 can be moved further rearward.

In addition, a floor fixing cylinder F is provided at the rear lower portion of the structure 120 to prevent the structure 120 from being detached from the foundation rail R1.

Hereinafter, the operation of the present invention will be described.

The housing (H) is placed on the first top plate of the first work table (111) placed horizontally. Next, the cylinder C1 is operated to adjust the position of the first slider 112 while moving the first slider 112 along the guide rail 111a, and the cylinder C2 is operated to move the first slider 112 114 are pushed so that the housing H has an appropriate position and height.

In this state, the cylinder 116 'is operated to rotate the second arm 115' by 90 °. At this time, the second upper plate 114 'of the second work table 111' is brought into close contact with the housing H.

In this state, the cylinders 116 and 116 'again operate to rotate the first arm 115 and the second arm 115' in the opposite direction by 90 °. At this time, the housing H is seated on the upper surface of the second upper plate 114 'of the second work table 111', and the second slider 112 'moves the guide rail 111'a by the operation of the cylinder C3 And the second upper plate 114 'is moved up and down by the operation of the cylinder C4 to adjust the position and height of the housing H again.

When the housing H is put in the correct position of the second upper plate 114 ', when the chain 162 is rotated by the operation of the motor M1, the chain 162 again rotates the structure wheel 161 to rotate the base rail R1 The structure 120 is moved toward the housing H.

When the structure 120 reaches a predetermined position, the push cylinder 121a is operated to temporarily fix the housing H on the second upper plate 114 ', and then, by the operation of the motor M2 and the motor 168, The first moving plate 130 and the second moving plate 140 are adjusted to the right positions while moving along the guide rails R2 and R3, respectively.

The extraction arm 124 is sequentially inserted into the housing H by operating the cylinder C and the push cylinder 121 sequentially while the extraction arm 124 is positioned above the center of the housing H. [

When the extraction arm 124 is inserted into the housing H, the rod cylinder 123 is operated to open the lower portion of the extraction arm 124. At this time, the ring 124a of the extraction arm 124 has the bearing B It takes the bottom.

At this time, the push cylinder 121 and the cylinder C are operated to lift the extraction arm 124 holding the bearing B upward.

The motor M1 then operates to return the structure 120 to its original position and when the structure 120 returns to its original position the cylinder C5 is activated to withdraw the auxiliary guide rail R4 The first moving plate 130 is retreated along the auxiliary guide rail R4 so that the bearing B is positioned behind the structure 120. [

Although not shown in the drawing, a cleaning carriage is provided on the rear side of the structure 120, and the rod cylinder 123 is operated to cause the extraction arm 124 to drop onto the carriage so as to place the bearing B thereon.

The present invention is characterized in that means for adjusting the direction and position of the housing is provided on one side of the base rail and extraction means for extracting the bearing from the inside of the housing while moving along the base rail is provided on the other side of the base rail, It has a unique effect that the bearing can be extracted more simply and quickly.
