A curved printing glass cassette 100 according to an embodiment of the present invention basically includes a frame 10 and a glass support 50.

The frame 10 includes a pair of side panels 20 provided with a space (glass loading space) in which the curved printing glass 4 is to be loaded, and a pair of side panels 20 having a plate shape, (40). And a bottom panel 11 may be additionally provided at the bottom.

The frame support 40 together with the side panel 20 determines the size of the glass loading space. The frame support 40 is detachably coupled to the side panel 20 by a fastening member such as a bolt. The frame support 40 may be coupled to the edge of the side panel 20 to maximize the glass loading space, but is not limited thereto.

The side panel 20 may be provided with an inlet and outlet hole 21 through which the washing water and the like can flow in and out of the curved printing glass 4 loaded in the glass loading space. The inlet and outlet holes 21 may be symmetrically arranged with respect to the center of the side panel 20.

The inlet and outlet holes 21 can be utilized in various processes for glass. For example, the washing water may flow into the glass loading space through the inlet and outlet holes 21 or may be discharged to the outside through the inlet and outlet holes 21 after the washing is completed.

In addition, the inflow and outflow holes 21 reduce the weight of the frame 10 and reduce the material required for manufacturing the frame 10.

The side panel 20 may have a two-row structure in which upper and lower portions of the position adjuster 30 are disposed to horizontally move the glass support 50 in a horizontal direction and to fix the glass support 50 in a desired position. The glass support 50 assembled to the lower position adjuster 30 functions as a lower support and the glass support 50 assembled to the upper position adjuster 30 can function as a side support.

The position adjustment unit 30 may include three elongated holes 31, 32, 33 extended in the horizontal direction. Positioning claws 36 and 37 are formed on the inner side lower portion of the upper elongated hole 31 and the upper side of the inner side surface of the lower elongated hole 33 so that the engagement protrusions 61 of the position adjusting cap 60 So that the position of the glass support 50 can be precisely adjusted. The direction adjusting unit 55 of the glass support 50 can be slidably fitted in the horizontal slit 32. [

The position adjusting unit 30 may be formed to face each of the pair of side panels 20. The position adjustment portions 30 formed on the respective side panels 20 are opposed to each other so that both ends of the glass support table 50 can be positioned perpendicular to the side panel 20 within the same range.

In the drawing, four upper position adjustment units 30 and lower position adjustment units 30 are provided for one side panel 20. Although it is shown that the position adjustment of one glass support 50 can be performed with respect to each one, it is only one embodiment, and depending on the design conditions, It is also possible that a plurality of glass supports 50 are assembled in the position adjusting unit so that the position adjustment can be performed.

The side panel 20 may be provided with a fixing hole for fixing the frame support 40 to a position where the curved printing glass 4 is not obstructed (for example, upper and lower ends or both lower ends) have.

The frame supports 40 are fixed to the fixing holes at both ends thereof so that the side panels 20 are spaced apart from each other by a predetermined distance to provide a glass loading space.

A frame supporting table 40 provided with a glass supporting part 52 on the outside may be fixed to the center part of the side panel 20 or a glass supporting part 40 may be provided outside the frame supporting table 40, 52 may be provided to function as a side support.

The glass support 50 is assembled between the pair of side panels 20 so as to be opposed to each other and supports the side or bottom of the curved printing glass 4 to be loaded in the glass loading space.

The glass support 50 functions as a side support or a lower support depending on its assembling position. The glass support 50 which is assembled to the position adjusting part 30 located on the upper side of the side panel 20 functions as a side support and the glass support 50 ) Function as a lower support.

The glass support 50 includes a shaft, a glass support 52, and a positioning cap 60.

The shaft is divided into a shaft body portion 51, a shaft end portion 54, and a direction adjusting portion 55. Shaft end portions 54 are provided at both ends of the shaft body portion 51 and direction adjusting portions 55 are formed at the ends of the shaft end portions 54.

A glass support portion 52 is protruded from the outside of the shaft body portion 51. The glass support 52 may be a rotator having a recessed groove 53 having a left-right asymmetric structure.

Referring to FIG. 6, the recessed portion 53 includes a first oblique surface 111 having a first inclination and a second oblique surface 112 having a second inclination. A horizontal plane 113 having a predetermined width is placed between neighboring recessed grooves 53. And the inclination angle of the oblique face, that is, the first inclination and the second inclination may be different from each other.

Assuming an imaginary line L lying in a direction perpendicular to the shaft body portion 51 at the lowest point of the recessed portion 53, the angle between the vertical imaginary line L and the first oblique surface 111 is A11 , And the angle between the vertical virtual line L and the second oblique surface 112 becomes A12. In this case, the total angle of the recessed portion 53 (i.e., the angle between the first and second oblique faces 111 and 112) is A1 (= A11 + A12).

In this embodiment, the angle A11 corresponding to the first oblique surface 111 of the curved surface of the curved printing paper 4 is larger than the angle A12 corresponding to the second oblique surface 112. [

In addition, the inter-angle A11 corresponding to the first oblique surface 111 may have the following relationship with the curved surface printing glass 4 to be stacked. The curved surface printing glass 4 has a curved surface portion 6 corresponding to a curved surface display portion placed in the recessed groove portion 53 and can have a predetermined curvature.

At this time, depending on the curvature of the curved surface portion 6 of the curved printing glass 4, when the intermediate portion of the curved printing glass 4 lies perpendicular to the shaft body portion 51, (A2) corresponding to the angle between the corner tangent (L1 in Fig. 7 and the tangent to the edge of the curved portion) of the curved surface portion 6 corresponding to the portion 5 and the curved surface display portion 3, The angle obtained by adding the predetermined margin A3 to the angle A11 with respect to the first oblique surface 111 can be made.

The curved printing glass cassette 100 according to the present embodiment can be loaded with curved printing glasses having various sizes and corner curvatures. Therefore, the inter-angle A11 of the recessed portion 53 with respect to the first oblique surface 111 is determined so as to have a margin A3 of a predetermined size or more with respect to the curved printing glass having the maximum curvature of curvature among the curved printing glass to be loaded . For example, the angle A11 may be on the order of 60 degrees ([deg.]).

When the second oblique surface 112 has the same inclination as the first oblique surface 111, the curved printing glass 4 will be able to be loaded in any direction. However, in this case, the space occupied by the first oblique surface 111 and the second oblique surface 112 is widened, so that the number of the curved surface printing glass 4 that can be stacked on the glass support table 50 of a limited length is reduced.

Therefore, the second oblique surface 112 is formed at an angle of inclination sufficient to facilitate loading and unloading of the curved printing paper 4 while stably supporting the edge of the curved printing paper 4, . For example, the angle A12 may be on the order of 25 degrees (degrees).

A point where the first and second oblique faces 111 and 112 meet at the recessed groove 53 and a point where the first oblique face 111 and the horizontal plane 113 meet and the second oblique face 112 and the horizontal plane 113 The point of meeting may be the R-cut process (see R1, R2, R3). It is possible to prevent the occurrence of damage on the corner portion and the surface of the curved printing paper 4 loaded in the recessed groove portion 53 by the R cutting process.

According to one embodiment, the glass support 52 may have a detachable structure comprising a plurality of glass support pieces 90a to 90e (see FIG. 11).

The glass support pieces 90a to 90e have a structure in which a shaft insertion hole is formed therein and a plurality of recessed portions 53 are formed around the glass support pieces 90a to 90e. A plurality of glass support pieces 90a to 90e are successively fitted into the shaft body portion 51 of one shaft and assembled to complete one glass support portion 52. [ At this time, the plurality of glass support pieces 90a to 90e can be coupled to the shaft body portion 51 in such a manner that they are attached using an adhesive means such as an adhesive.

It is possible to prevent the recessed portions 53 from being spaced apart from each other between the continuous glass support pieces 90 during assembly and to prevent the recessed portions 53 from being placed on both ends of the glass support piece 90. [ To this end, a part of the horizontal plane 113 is placed on both ends of the glass support part 52 formed around the glass support piece 90. When a part of the horizontal planes 113 at both ends are assembled together, And the like.

The glass support piece 90 according to the present embodiment is a portion directly in contact with the curved printing glass 4 and can be made of a soft material so as not to damage the curved printing glass 4. [

According to another embodiment, the glass support 52 may be formed as an integral structure with respect to one shaft (see Fig. 12). Here, the glass support 52 may be made of PTFE (polytetrafluoroethylene). In the case of the PTFE integral structure, there is an advantage that the shrinkage and expansion do not occur even when heat is applied, and the original shape (dimension) is maintained.

A method of manufacturing the glass support 50 having the integral structure is as follows.

The knurling region 92 is formed by knurling both ends of the shaft body portion 51, more specifically, at both ends of the shaft body portion 51 (Step S200). The knurling region 92 may be formed by a portion having a rough and irregular surface in order to prevent slippage, by serration in a horizontal or an oblique direction or by machining a serration on the outer surface. The knurling region 92 enhances the adhesion between the shaft body portion 51 and the PTFE material and allows the shrinkage expansion to be complemented in some knurling regions 92 when the product is subjected to heat.

The shaft having the knurled region 92 formed therein is placed in a chamber containing the PTFE material, followed by molding (Step S210). The molding process may include filling and compression, sintering, and annealing processes.

A cylindrical support 94 having a structure in which the PTFE layer compressed with the PTFE material is wrapped around the outer surface of the shaft body portion 51 through the molding process may be formed first. The PTFE layer constituting the outer layer of the cylindrical support 94 can be fixedly coupled to the shaft body portion 51 by the knurling region 92.

Here, the radius (R1 in Fig. 12) of the cylindrical support 94 is the distance from the central axis of the shaft body portion 51 to the horizontal surface 113 in the final finished glass support 50 (W1 in Figs. 6 and 12 ). ≪ / RTI > That is, the outer surface of the cylindrical support 94 is the horizontal surface 113 of the finished glass support 50.

Next, a recessed groove 53 is formed in the cylindrical support 94 through a cutting process (step S220). The recessed groove 53 may be formed to have a first oblique surface 111 and a second oblique surface 112 which are asymmetric as described above with reference to the drawings.

Referring to FIG. 8, the direction adjusting unit 55 may have a square shape in which the corner is R-cut or C-cut when viewed from the front. Of course, the corner may have a square shape without being cut or may have a circular shape.

Here, the length of the shaft body portion 51 and the shaft end portion 54 extending to form the step 56 inwardly at both ends thereof are the same as the interval between the inner side surfaces of the pair of side panels 20 . Therefore, the direction adjusting unit 55 can be fitted to the center long hole 32 of the position adjusting unit 30 formed on the side panel 20. [

The direction adjusting portion 55 is a portion slidably fitted in the central long hole 32 of the position adjusting portion 30 and the size thereof corresponds to the thickness of the central long hole 32. [ That is, the distance between the opposing sides of the direction adjusting unit 55 may be the same as the thickness of the central slot 32 or may be small within an error range.

The shaft end portion 54 has a smaller diameter than the shaft body portion 51 so that a step 56 is formed at a point where the shaft body portion 51 and the shaft end portion 54 meet.

At this shaft end 54, a positioning cap 60 can be assembled.

The position adjusting cap 60 is opened at one side and has a spring receiving portion 62 formed therein and a through hole 63 communicating with the spring receiving portion 62 is formed on the other surface.

A pair of locking protrusions 61 protrude from the outside of the other surface of the positioning cap 60. The distance between the pair of locking projections 61 corresponds to the distance between the position adjusting teeth 36 and 37 formed in the upper long hole 31 and the lower long hole 33 of the position adjusting portion 30, Each of the pair of locking projections 61 is caught by the valleys of the position adjusting teeth 36 and 37 formed in the upper and lower long holes 31 and 33, respectively.

The through hole 63 has a diameter through which the shaft end portion 54 can penetrate so that the positioning cap 60 having a length smaller than the shaft end portion 54 can be slidably moved at the shaft end portion 54 .

When the position adjusting cap 60 is assembled to the shaft end portion 54, a predetermined empty space is formed between the shaft end portion 54 and the position adjusting cap 60, and a spring 80 is inserted into the space. .

The diameter of the spring 80 is larger than the shaft end portion 54 and smaller than the shaft body portion 51 so that the spring 80 can be engaged with the shaft end portion 54 while being caught by the step 56. [ That is, after the spring 80 is fitted to the shaft end portion 54, the positioning cap 60 is assembled.

One end of the spring 80 is in contact with the step 56 and the other end is in contact with the bottom surface of the spring receiving portion 62 of the position adjusting cap 60. The spring 80 has an elastic force and is capable of responding to a change in distance between the step 56 and the bottom surface of the spring receiving portion 62 depending on the position of the position adjusting cap 60 assembled to the shaft end portion 54 The restoring force acts in a direction in which the distance between the step 56 and the bottom surface of the spring receiving portion 62 increases, that is, the position adjusting cap 60 moves away from the center of the shaft body portion 51. [

The direction adjusting unit 55 is formed with a fastening hole 58. The direction adjusting unit 55 is fitted to the center long hole 32 and then is fastened to the outside of the side panel 20 by fastening members 70, The position of the glass support table 50 can be more firmly fixed. Here, the fastening member 70 may be, for example, a bolt bolt which is easy to fasten and disassemble.

The process of assembling the glass support table 50 in the curved printing type glass cassette 100 according to the present embodiment is as follows.

First, a frame 10 having a glass loading space is manufactured by using the side panel 20 and the frame support 40.

In the case of the glass support member 50, after the spring 80 and the positioning cap 60 are assembled to the shaft end portion 54, an external force is applied to the guide member 50 so that the direction adjusting portion 55 formed at the end of the shaft end portion 54 is positioned Hole 63 of the adjustment cap 60 so as to be exposed to the outside.

The direction adjusting unit 55 exposed to the outside is fitted to the center long hole 32 of the position adjusting unit 30 to be assembled. At this time, the glass support 50 functions as a side support when the position adjusting unit 30 is at the upper side, and the glass support 50 functions as a lower support when the position adjusting unit 30 is at the lower side. When the direction adjusting portion 55 is engaged, the rotation of the glass supporting table 50 is prevented by the shape of the direction adjusting portion 55, thereby suppressing the generation of frictional force between the glass supporting table 50 and the curved surface printing glass 4, Can be prevented.

The position adjusting cap 60 is urged toward the inner side surface of the side panel 20 by the restoring force of the spring 80 and the engaging protrusion 61 is pressed against the inner surface of the side panel 20 by the restoring force of the spring 80, (36, 37) formed in the upper and lower slots (31, 33), thereby restricting the positional movement in the horizontal direction.

In addition, the glass support 50 may be secured using a fastening member 70 for a more rigid position fix.

In the case where the position of the assembled glass support 50 is finely adjusted in accordance with the size and / or shape of the curved print glass 4a to be loaded, the following procedure is followed.

First, when the fastening member 70 is fastened, the fastening member 70 is disassembled (see Fig. 10 (a)).

Then, an external force is applied to the position adjusting cap 60 toward the center of the shaft so that the engaging protrusion 61 deviates from the position adjusting teeth 36, 37. 9 (a)) to the released state (Fig. 9 (b)).

The glass support base 50 is slid along the central long hole 32 to adjust the position thereof (see Fig. 10 (b)).

The position adjusting cap 60 is urged toward the inner side surface of the side panel 20 by the restoring force of the spring 80 and the engaging projection 61 is moved to the position And is caught by the position adjusting teeth 36, 37 at the adjusted position. 9 (a)) in the released state (Fig. 9 (b)).

Thereafter, by fastening the fastening member 70, the glass support 50 can be firmly fixed at the adjusted position.

According to the present embodiment, the position of the glass support can be finely adjusted by simple operation as described above, and it is possible to prevent the right / left deviation at the adjusted position, so that it is possible to adapt to various sizes and / So that it is possible to cope with the problem and to provide stable support.

In the above description, it is assumed that both the upper and lower position adjusting units are provided, but the present invention is not limited thereto.

It is needless to say that one or more fixed supporting posts provided with a glass supporting portion instead of a glass supporting portion may be provided at a certain interval or at an arbitrary interval so as to function as a lower supporting portion.
