1 to 3 to support the embodiment of the present invention, six first ball splines 162 are provided in all of the first blocks 120 and six first ball splines 162 are provided in the second blocks 122, The number of the splines 172 is not limited as long as the ring belts 200 to be described later are wound in an even number.

The first ball spline 162 installed in the first block 120 and the second ball spline 172 installed in the second block 122 are provided in the same number, 162 and 172 are arranged on the same line.

For reference, six first ball splines 162 are referred to as first 1-1 ball splines to first 1-6 ball splines, and six second ball splines 172 are referred to as first- Are referred to as a 2-1 ball spline to a 2-6 ball spline to help understand the explanation.

If it is assumed that a 1-1 ball-spline is provided from one end of the first block 120 and a 1-6 ball spline is provided at the other end, the 1-1 ball- The splines are spaced apart to form a set in which the ring belt 200 is wound. The first to third ball splines and the first to fourth ball splines are also spaced apart from each other, The first and second ball splines and the first to sixth ball splines are also spaced apart to form one set of belts 200 that are wound and another ring belt 200 is wound .

Further, the first to third ball splines and the first to fourth ball splines and the first to fifth ball splines, in which the ring belts 200 are not wound together, They can be disposed as close as possible within a range in which interference does not occur.

On the other hand, it is assumed that a plurality of second ball splines 172 provided in the second block 122 are provided with a 2-1 ball spline from one end and a 2-6 ball spline installed on the other end The second-1 ball spline and the second-2 ball spline are arranged in a spaced-apart state to form a set in which the ring belt 200 is wound, and the second-third ball spline and the second- The second splines and the second 2-6 ball splines are also spaced apart from each other by a predetermined distance so as to form another set of ring belts (200) (200) is wound.

The second-2 ball spline and the second-second ball spline, which are positioned in connection with each other and in which the ring belt 200 is not wound around each other, and the 2-4 ball spline and the 2-5 ball spline, They can be disposed as close as possible within a range in which interference does not occur.

The first ball spline 162 and the second ball spline 172 may be positioned so as to correspond to each other on the same line.

For example, the first 1-1 ball spline of the first ball spline 162 and the 2-1 ball spline of the second ball spline 172 may be positioned in a collinear manner.

The first ball spline 162 and the second ball spline 172 are installed so as to penetrate through the first block 120 and the second block 122 respectively and the first block 120 and the second block 122 (Not shown) of the first block 120 and the second block 122. The first block 120 and the second block 122 can be moved together with each other according to the horizontal movement of the first block 120 and the second block 122. [

The first shaft 160 and the second shaft 170 may be inserted into the first ball spline 162 and the second ball spline 172, respectively.

As shown in FIG. 4, the first shaft 160 and the second shaft 170 are formed in a cam shape in which concave portions and convex portions are formed instead of a shaft having a circular section, The first ball spline 162 and the second ball spline 172 may be formed with insertion holes corresponding to the cam shape.

Accordingly, when the first shaft 160 and the second shaft 170 are rotated, the first ball spline 162 and the second ball spline 172 can rotate together and the first shaft 160 and the second ball spline 172 can rotate. The first ball spline 162 and the second ball spline 172 can be moved in the longitudinal direction with respect to the two-shaft 170, and the detailed operating relationship therebetween will be described later in detail.

On the other hand, the coupler 180 can couple or separate the ends of the first shaft 160 and the second shaft 170.

That is, a first shaft 160 rotatably installed with respect to the first block 120 among the pair of blocks 120 and 122, and a second shaft 160 rotatably installed with respect to the second block 122 170 can be engaged or disengaged.

For example, the first shaft 160 installed in the first ball spline 162 inserted in the first ball spline 162 and the second shaft 160 inserted into the second -1 ball spline in the second ball spline 172, By joining the ends of the shaft 170, the first shaft 160 and the second shaft 170 can be formed into a single module so that the first shaft 160 and the second shaft 170 can rotate at the same time.

5, the coupler 180 is connected to one end of the first shaft 160 and one end of the second shaft 170 in the same axial direction, 160 and a seating groove 182 for receiving a portion of the end of the second shaft 170. [

At this time, the seating groove 182 formed in the first and second members is formed into a groove having a convex portion and a concave portion corresponding to the sectional shapes of the first shaft 160 and the second shaft 170 . That is, with the first member and the second member engaged to hold both ends of the first shaft 160 and the second shaft 170, the overlapping mounting grooves 182 of the first member and the second member The first ball spline 162, and the second ball spline 172, as shown in FIG.

Accordingly, the coupler 180 is rotated in conjunction with the rotation of the first shaft 160, and the second shaft 170 is interlocked with the coupler 180, thereby facilitating the rotation.

For reference, the coupler 180 is divided into a first member and a second member, and the first member and the second member may be mutually engaged or separated as a coupling member such as a bolt 186 and a nut 188 However, it is needless to say that any conventionally known method such as a clamp can be applied as long as the first shaft 160 and the second shaft 170 are combined or separated to be positioned on the same axis.

The coupler 180 separates the first shaft 160 and the second shaft 170 as necessary so that a predetermined space is formed between the first shaft 160 and the second shaft 170, The ring belt 200 can be easily inserted and removed through the space when the ring belt 200 wound around the ring belts 162 and 172 is replaced so that the replacement operation of the ring belt 200 can be easily performed , And the operational relationship therebetween will be described later in detail.

The first ball spline 162 and the first shaft 160 as described above and the second ball spline 172 and the second shaft 170 are rotated by the drive unit to be rotated, 200 can be rotated together with the same rotation speed.

The drive unit may be configured to include a plurality of pulleys 150, at least one drive motor 130, and at least one belt or chain 140.

A pulley 150 may be installed at one of the shaft ends of the first shaft 160 and the second shaft.

Although the pulley 150 is installed at one end of the first shaft 160 in the embodiment of the present invention, the pulley may be installed at one end of the second shaft 170, A pulley may be installed at one end of the first shaft 160 and the second shaft 170, respectively.

As described above, when the first 1-1 ball spline and the 1-2 first ball spline form a set in the first ball spline 162, the first shaft 1 inserted into the first 1-1 ball spline, The first shaft 160 inserted into the first ball spline and the first shaft 160 inserted into the first ball spline also constitute one set of pulleys and the pulleys installed at one end of the first shafts 160 constitute one set .

Thus, the pulleys constituting one set are wound by one belt or chain 140, and the belt or chain 140 can be rotated by the drive motor 130. [

The driving pulley 132 is connected to the belt or the chain 140 so that the driving pulley 132 is connected to the driving pulley 132 when the driving motor 130 is driven. So that the belt or chain 140 is rotated and the pulleys 150 constituting one set can be rotated.

The operation of the transfer device 100 according to the embodiment of the present invention will now be described.

1 and 2, when an electric signal is applied to at least one drive motor 130 to drive the drive pulley 132, the belt or chain 140 rotates, Accordingly, the pulleys 150 of each set connected to the belt or the chain 140 are interlocked and rotated.

Accordingly, each of the first shafts 160 connected to one end of each pulley 150 is rotated in conjunction with the first ball spline 162, and the first ball spline 162 is also rotated to rotate.

At this time, the first shafts 160 are not formed as a shaft having a circular cross-sectional shape, but are formed as camshafts having convex portions or concave portions formed on either one of them, and the first ball splines 162 The insertion holes corresponding to the cam shape are formed and inserted so that the first ball spline 162 rotates in conjunction with the rotation of the first shafts 160.

Accordingly, the ring belt 200 wound around the first ball splines 162 is rotated in conjunction therewith.

That is, the first 1-1 ball spline forming one set of the first ball splines 162 and the ring belt 200 wound around the 1st 1-2 ball spline are rotated, and the first -3 ball spline and the ring belt 200 wound on the first-fourth ball spline are made, and the ring gear belt 200 wound on the first-fifth ball spline and the first-sixth ball spline 200).

In addition, the first shafts 160 rotate together with the first shafts 160, and the second shafts 170, to which the one ends of the first shafts 160 are coupled by the coupler 180, The second ball spline 172 is rotated in conjunction with the second ball spline 172.

At this time, the second shafts 170 are not formed as a shaft having a circular cross-sectional shape, but are formed as camshafts having convex portions or concave portions formed on either one of them, and the second ball splines 172 The insertion holes corresponding to the cam shape are formed and inserted so that the second ball spline 172 is rotated in conjunction with the rotation of the second shafts 170.

Accordingly, the ring belt 200 wound around the second ball splines 172 is rotated in conjunction with the rotation.

That is, rotation of the ring-shaped belt 200 wound around the 2-1 ball spline and the 2-2 ball spline constituting one set of the second ball splines 172 is performed, and the rotation of the ring- The rotation of the ring belt 200 wound around the -3 ball spline and the 2-4 ball spline is performed, and the rotation of the ring belt 200 wound around the 2-5 ball spline and the 2-6 ball spline 200 are also rotated.

A plurality of ring belts 200 wound around the first ball splines 162 and a plurality of ring belts 200 wound around the second ball splines 172 are rotated at the same speed, The glass G1 seated on the ring belts 200 is accurately conveyed in one direction at a constant speed.

Reference numerals 190 in the drawings denote guide rollers disposed between the ball splines 162 and 172 to prevent the ring belt 200 from sagging and to guide the rotation of the ring belt 200 in one direction.

3, when a glass G1 having a predetermined size is transported and a glass G2 having a different size, for example, a small size, is transported, The distance between the blocks 120 and 122 may be reduced and the transfer may be performed as described above.

That is, if the gap between the pair of blocks 120 and 122 is reduced by a gap adjusting device such as a ball screw, a linear motor, a hydraulic or pneumatic cylinder, the small size glass G2 can be transported in a state of being seated.

When the interval between the pair of blocks 120 and 122 is reduced, the first block 120 and the second block 122 move in opposite directions, as shown in FIG. 3. At this time, A first ball spline 162 rotatably installed on the first block 160 and a second ball spline 172 rotatably installed on the second block 122 are disposed on the first shaft 160 and the second shaft 162, 2 shaft 170 in the longitudinal direction.

In this case, since the pair of blocks 120 and 122, that is, the first block 120 and the second block 122 are horizontally moved along the guide rail 300 installed on the base plate 110, The spacing can be adjusted while maintaining a side-by-side relationship.

Conversely, when the glass G1 having a small size is transported while the distance between the pair of blocks 120 and 122 is narrowed as shown in Fig. 3, As described above, the distance between the pair of blocks 120 and 122 may be increased by a gap adjusting device such as a ball screw, a linear motor, a hydraulic or pneumatic cylinder, or the like, as shown in FIGS.

As described above, when the glass (G1, G2) of various sizes is transferred using the transfer device 100 according to the embodiment of the present invention, the glass (G1, G2) There may be a case where the belt 200 is damaged or the tension is lost so that the belt 200 can not exhibit its function.

In this case, the ring gear 200 is replaced with a new one. In the transfer apparatus 100 according to the embodiment of the present invention, the first shaft 160 and the second shaft 170 are separated by the coupler 180 The ring belt 200 can be easily replaced by the detachment of the coupler 180.

5, the coupler 180 coupling the first shaft 160 and the second shaft 170 is disengaged as the disengagement of the coupling members such as the bolts 186 and the nuts 188 The first shaft 160 and the second shaft 170 can be separated from each other and the ring 170 wound on the circumferential groove 164 of the ball splines 162 and 172, The belt 200 is pulled toward the end of the first shaft 160 or the second shaft 170 or the new ring belt 200 is pulled in from the end of the first shaft 160 or the second shaft 170 So that the operation of replacing the ring belt 200 can be carried out very easily by fitting it into the peripheral groove 164 of the ball splines 162 and 172 again.

In other words, when the ring belt 200 is to be replaced, the ball splines 162 and 172 are separated from the blocks 120 and 122 so that the replacement operation is very troublesome. However, in the embodiment of the present invention, The replacement of the ring belt 200 can be easily performed only by separating the coupler 180 coupling the two separated shafts 160 and 170. [

For example, the transfer device 100 according to the embodiment of the present invention is described as an example for selectively transferring glass G1 and G2 having different sizes. However, in addition to glass, The substrate, the wafer, etc.).

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
