DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pallet transporting apparatus according to a preferred embodiment of the present invention and a pallet for transporting the pallet transporting apparatus will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

1 is a perspective view showing a pallet transporting apparatus 100 according to an embodiment of the present invention.

Referring to the drawings, the pallet transporting apparatus 100 may have a support block 110, an elevating unit 130, a base 150, and a transporting unit 170.

The support block 110 is a structure for supporting the pallet 200.

The elevating unit 130 is configured to elevate at least a part of the supporting block 110 along the elevation direction E with respect to the rest. At least a portion of the support block 110 may be a portion that supports the pallet 200.

The elevating unit 130 may have a driving body 131 and a moving body 133. [ The driving body 131 is configured to be moved along the crossing direction C that crosses the up and down direction E. The driven body 133 is configured to be pushed up along the lifting direction E by the movement of the driving body 131. [ The driven body 133 is connected to at least a part of the support block 110 and is configured to be moved up and down with it.

The base 150 is disposed below the driven member 133 and guides the driving member 131 along the crossing direction C. [ The base 150 may also be arranged to support a portion of the support block 110.

The conveying unit 170 is formed to extend along the crossing direction C and conveys the base 150 along the crossing direction C.

According to this configuration, the support block 110, the elevation unit 130, and the base 150 can be transported along the crossing direction C by the transport unit 170.

The support block 110 and the like are stopped at the transported position and at least a part of the support block 110 can be lifted and lowered by the lifting unit 130 along the lifting direction E. [

This rise during the ascending and descending is achieved by moving the driven body 131 engaged with the driving body 131 in the ascending and descending direction E by moving the driving body 131 along the crossing direction C. Thereby, the pallet 200 can be located at a height set along the lifting direction E. The driven body 133 is supported by the driving body 131 moved along the crossing direction C intersecting with the up-and-down direction E, so that the driven body 133 can be firmly held at the elevated position.

The lowering is achieved by a part of the moving body 133 and the supporting block 110 being lowered by their own weight as the driving body 131 moves in a direction different from the preceding and the other direction along the crossing direction C. At this time as well, since the driven body 131 supports the driven body 133, the driven body 133 and the like gradually descend.

The supporting block 110, the elevating unit 130, and the base 150 will be described with reference to Figs. 2 and 3. Fig.

FIG. 2 is a perspective view of the support block 110, the elevation unit 130, and the base 150 of FIG. 1 viewed from one direction, and FIG. 3 is a perspective view thereof as viewed from a direction different from FIG.

Referring to these drawings, the support block 110 may have a fixing module 111 and a moving module 116.

The fixing module 111 is a portion fixed to the base 150. The securing module 111 may be arranged substantially perpendicular to the base 150.

The moving module 116 is relatively movably connected to the fixing module 111 along the lifting direction E thereof. To this end, the transfer module 116 may be arranged to face the securing module 111. The transfer module 116 may also be arranged substantially perpendicular to the base 150.

The transfer module 116 may have a pedestal 117, clamping units 119 and 120, a moving cylinder 121, and a leveling unit 125.

The pedestal 117 is a structure for supporting the pallet 200. The pedestal 117 can be a plane perpendicular to the elevation direction E. The pedestal 117 may have an opening hole 118 formed at the center thereof.

The clamping units 119 and 120 are for clamping the pallet 200 placed on the pedestal 117. The clamping units 119 and 120 may have a reference clamper 119 and a variable clamper 120. The reference clamper 119 is installed on one side of the pedestal 117 and can be fixed to the pedestal 117. On the other hand, the variable clamper 120 is installed on the other side of the pedestal 117 in correspondence with the reference clamper 119. Further, the variable clamper 120 is formed so as to be displaced so as to be closer to or away from the reference clamper 119.

The moving cylinder 121 is configured to move the variable clamper 120 toward or away from the reference clamper 119. The moving cylinder 121 may employ a pneumatic cylinder. Further, the moving cylinder 121 can be installed in the opening hole 118 of the pedestal 117.

The leveling unit 125 is a configuration that allows the pedestal 117 to be fixed by adjusting the level with respect to the rest of the moving module 116. [ This will be described with reference to Figs. 5 and 6. Fig.

2 and 3, the lifting unit 130 can have the driving body 131 and the driven body 133 as described above. Here, the driving body 131 may be a driving cam having an inclined face 132 whose height increases from one end to the other end. The driven member 133 may be a driven roller corresponding to the inclined surface 132 of the drive cam. Here, the driving body 131 is moved in the cross direction C by the operation of the driving cylinder 135 connected to the driving body 131.

The lifting unit 130 may further have a lifting rail 137, a slider 138, a biasing member 139, and a stopper 140.

The lifting rails 137 are connected to the fixing module 111 of the support block 110. The lifting unit 130 is arranged along the lifting direction E.

The slider 138 is connected to the movement module 116 of the support block 110 and is slidably engaged with the lift rail 137.

The biasing member 139 resiliently biases the moving module 116 toward the securing module 111. To this end, the biasing member 139 may be an elastic body having opposite ends connected to the fixing module 111 and the moving module 116, respectively. Specifically, the biasing member 139 is illustrated as a coil spring arranged in the elevation direction E in this embodiment.

The stopper 140 is a structure for restricting the height at which the movement module 116 ascends with respect to the fixed module 111. [ The stopper 140 may have a bracket 141 and a restricting pin 142. The bracket 141 is disposed so that one side is connected to the moving module 116 and the other side is extended toward the fixing module 111 side. On the other side of the bracket 141, a limiting hole 141a is formed. The restriction hole 141a may be a long hole extending in the elevation direction E. The restriction pin 142 is protruded from the fixing module 111 and inserted into the restriction hole 141a.

The base 150 may have a base plate 151 and a guide rail 153. The base plate 151 may have a generally plate-like shape. The guide rails (153) are arranged on the base plate (151) along the cross direction (C). The guide rail 153 is slidably engaged with the driving body 131.

According to this configuration, the driving body 131 can be moved in the cross direction C by being guided by the guide rail 153 by the operation of the driving cylinder 135. The moving body 133 is supported by the lower portion of the inclined surface 132 and is gradually supported by the higher portion due to the movement of the driving body 131,

With the lifting of the moving body 133, the moving module 116 to which the moving body 133 is connected is also raised. At this time, the elevation of the moving module 116 relative to the fixing module 111 is achieved by the relative sliding of the lifting rail 137 and the slider 138. In addition, the movement of the moving module 116 relative to the fixing module 111 may be limited by the stopper 140. [ Further, in order to return the elevated moving module 116 to the original position with respect to the fixing module 111, the biasing member 139 is operated.

Next, the structure in which the support block 110, and in particular the pedestal 117, clamps the pallet 200 will be described with reference to Fig.

4 is a side view of a recessed portion showing a state in which the pallet 200 is seated on the support block 110. Fig.

Referring to FIG. 2, a receiving groove 215 may be formed on a side surface of the pallet 200. The receiving groove 215 is substantially in the form of a V (V), and may have a downward sloped surface.

In response to the pallet 200, the reference clamper 119 and the variable clamper 120 are engaged with the receiving recess 215 to clamp the pallet 200. At this time, the reference clamper 119 and the variable clamper 120 have pressing protrusions 119, 120 corresponding to the receiving recesses 215.

The pressing protrusions 119 and 120 are formed with inclined surfaces 119a and 120a. The inclined surfaces 119a and 120a may be an upward inclined surface so as to be engaged with the inclined surfaces of the receiving recesses 215. [

According to this configuration, the force applied to the pallet 200 by the press protrusions 119 and 120 through the receiving recess 215 includes a force in the vertical direction as well as a force in the horizontal direction.

As a result, not only the pallet 200 is held in the horizontal position, but also in the vertical direction, the pallet 200 can be strongly adhered to the support block 110 and supported without a gap.

Next, the leveling unit 125 described above will be described.

FIG. 5 is an exploded perspective view showing the leveling unit 125 of FIG. 2, and FIG. 6 is a sectional view showing a state where the leveling unit 125 of FIG. 5 is fastened to the pedestal 117.

Referring to these figures, the leveling unit 125 may have an upper nut 126, a lower nut 127, and a crimp bolt 128.

The upper nut 126 may have a wrench groove 126a, a bolt groove 126b, a screw thread 126c, and a polygonal protrusion 126d. The wrench groove 126a is a structure for accommodating the wrench. The bolt groove 126b is communicated with the wrench groove 126a and penetrates to the polygonal protrusion 126d. The thread 126c is formed on the outer surface and is fastened to the thread of the thread groove 117a of the pedestal 117.

The lower nut 127 may have a projection groove 127a for receiving the polygonal projection 126d of the upper nut 126. [ At this time, the inner surface of the projection groove 127a has a polygonal section corresponding to the polygonal projection 126d. The lower nut 127 has threads 127b exposed on its outer surface. The thread 127b is screwed into the thread of the thread groove 117a.

And the compression bolt 128 is inserted into the bolt groove 126b.

The upper nut 126 is connected to the lower nut 127 while the polygonal projection 126d of the upper nut 126 is fitted in the projection groove 127a of the lower nut 127. [ In this state, it is fitted into the screw groove 117a of the pedestal 117.

At this time, when a wrench is inserted into the wrench groove 126a and turned, the upper nut 126 and the lower nut 127 are rotated together to be inserted into the screw groove 117a. In the process, the threads 126c and 127b of the upper nut 126 and the lower nut 127, respectively, which are spaced apart from each other are removed by the compression of the compression bolt 128, (127) are brought into complete contact with each other.

In other words, the degree of tightness of the upper and lower nuts 126 and 127 can be adjusted according to the tightness of the compression bolt 128. Thereby, the leveling unit 125 located at the four corners of the pedestal 117 can be operated to adjust the level of the pedestal 117.

Next, the structure of the pallet 200 transported by the pallet transporting apparatus 100 or more will be described with reference to Fig.

7 is an exploded perspective view of the pallet 200 of FIG.

Referring to this figure, the pallet 200 supports the lens barrel LH. The pallet 200 may have a lower plate 210 and an upper plate 230.

The lower plate 210 may have a body 211, a mounting portion 213, a receiving groove 215, and an alignment hole 217.

The body 211 has the form of a generally rectangular plate. The mounting portion 213 protrudes from the center of the body 211. The receiving groove 215 may be formed on the side surface of the body 211 as described above. The alignment hole 217 corresponds to the alignment pin 123 (Fig. 2) of the pedestal 117, and is opened to receive the alignment pin 123.

The upper plate 230 may have a body 231 and a seating groove 233.

The body 231 has the form of a generally rectangular plate. The body 231 may be detachably mounted on the mounting portion 213 of the lower plate 210. The seating groove 233 is a portion where the lens barrel LH is seated.

With this arrangement, the pallet 200 can be firmly clamped to the pedestal 117, as described above with reference to Fig.

In addition, the upper plate 230 of different sizes can be exchanged according to the size change of the barrel LH. Thereby, it is possible to prevent waste due to replacement of the pallet 200 as a whole.

The pallet transporting apparatus and the pallet to which the pallet transporting apparatus and the pallet are transported are not limited to the construction and operation of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
