Description

  The present invention relates to a plate glass transfer device (Apparatus for transferring of glass panel), and more particularly to a plate glass transfer device provided with an air floating portion, a suction transfer portion, and a suction turning machine. The plate glass transport device of the present invention sucks and transports the plate glass to the center of the work table in the state where the plate glass is air-floated, turns the plate glass at the place by the suction turning machine, and then discharges it again by the suction transport device. Through the method, the plate glass is conveyed and rotated in a state where the contact between the conveying means and the rotating means and the plate glass is minimized, so that the surface damage occurrence rate of the plate glass can be significantly reduced. Therefore, the product quality can be enhanced. In addition, by making it possible to turn the sheet glass through the adsorption method, the sheet glass can be turned quickly and easily without the need for a separate contact turning device for turning the sheet glass, thereby improving the reliability of the apparatus. In addition, the work efficiency can be generally improved by rapid conveyance and rotation through the adsorption method. In addition, not only using the suction turning machine but also using the air floating part and the suction transport part, the sheet glass is suctioned and transported by the suction machine in the air floating state, as well as the transport of the plate glass through the cross-positioned suction machines A change of direction can also be made possible.

  In general, the plate glass direction changing device is a diverter system that moves the plate glass that has been transported on the workbench in the direction of travel, or that is transported by changing the direction in a perpendicular direction, and on the workbench. It can be roughly divided into a turn system in which the conveyed plate glass is advanced in the traveling direction or rotated at the place and then conveyed in a desired direction.

  Among such direction changing devices, the diverter-type plate glass direction changing device can only change the plate glass conveyed on the workbench at a right angle only in the traveling direction, and the plate glass itself is placed in its place. Could not rotate. A turn type plate glass direction changing device for solving the problem of the inability to rotate such a diverter type plate glass has been presented. An example of such a conventional turn type direction changing device is schematically shown.

  As shown in FIG. 1 to FIG. 6, a plate glass conveying device according to an embodiment of the present invention includes a work table 10, an air floating portion 20 arranged at the upper center of the work table 10 at a certain height, It comprises a suction turning machine 40 disposed on the upper part of the floating part 20 and first and second suction conveying parts 30 and 50 disposed at right angles to one side of the air floating part 20.

  The work table 10 has a quadrangular frame structure including a plurality of horizontal platforms 12 each having a vertical platform 11 standing upright at four corners and connecting the vertical platforms 11.

  The air floating portion 20 is disposed at a certain height above the work table 10, and is closely attached to the upper plate 21 having a plurality of air discharge holes 21 a formed on the surface and the bottom surface of the air discharge holes 21 a of the upper plate 21. An air fan 22 that generates air and an air chamber 23 including a filter 24 for filtering out foreign substances are provided on the air fan 22.

  Here, it is preferable that a filter 24 for filtering out foreign substances is provided on the air fan 22 of the air chamber 23.

  And the air discharge hole 21a of the air floating part 20 is formed over the entire length direction and width direction of the upper plate 21, and consists of a pair separated from each other at a constant interval in the same direction. The air discharge holes 21a are configured to intersect each other.

  In the upper plate 21 of the air floating portion 20, air leak holes 21 b are provided in portions other than the air discharge holes 21 a to allow air to leak downward so that air is not concentrated and saturated.

  The suction turning machine 40 is arranged at the upper center of the air floating portion 20 and sucks the plate glass 5 while being lifted up and down, and then rotates the suction glass. An adsorption plate 41 adsorbed on the upper surface, an adsorption rod 42 that moves the adsorption plate 41 up and down, and an adsorption cylinder 43 that drives the adsorption rod 42 are included.

  The suction plate 41 of the suction turning machine 40 is attached to each bottom surface of the cross-shaped support base 44 connected to the lower end portion of the suction rod 42 and includes a plurality of suction plates.

  The suction conveyance units 30 and 50 are arranged at right angles to one side of the air floating portion 20, and adsorbers 31 and 51 for sucking and conveying the conveyed glass sheet 5 in the length direction or the width direction. The machine 31, 51 has a structure including rotating belts 32, 52 for reciprocating back and forth in the length direction or reciprocating left and right in the width direction.

  Here, the rotating belts 32 and 52 have a kind of belt conveyor structure.

  The adsorbers 31, 51 are adsorbing plates 31a, 51a adsorbed on the upper surface or the bottom surface of the glass plate 5, adsorbing rods 31b, 51b for raising and lowering the adsorbing plates 31a, 51a, and adsorbing driving the adsorbing rods 31b, 51b. It consists of cylinders 31c and 51c.

  The adsorber 31 of the first adsorbing and conveying unit 30 is installed with the adsorbing plate 31a facing upward so that the bottom surface of the plate glass 5 can be adsorbed. The suction plate 51a is installed facing the lower part so that the upper surface of 5 can be sucked.

  A pair of rotating belts 32 and 52 of each of the suction conveyance units 30 and 50 are provided adjacent to each other, and on each of the rotating belts 32 and 52, the suction machines 31 and 51 are opposed to each other. It is desirable to be controlled by another controller (not shown) so as to reciprocate while changing the position with each other while being installed at the end of the direction.

  The first adsorbing / conveying unit 30 forms a cutout portion 26 by cutting out one side portion of the upper plate 21 of the corresponding air floating portion 20 over the entire length direction to form a cutout portion below the cutout portion 26. It arrange | positions in the space part 60, and the 2nd adsorption | suction conveyance part 50 consists of a structure arrange | positioned in the side part one side upper side of the air floating part 20. As shown in FIG.

  The pair of rotating belts 32 of the first suction conveyance unit 30 is provided with a receiving base 33 for supporting the rotating belts 32 on the bottom surface, and the receiving base 33 is connected to the moving rod 34a of the moving cylinder 34 and its width. When the adsorber 31 of the one-side rotating belt 32 adsorbs and conveys the plate glass 5 so that the respective distances can be moved in the directions, the adsorber 31 of the other-side rotating belt 32 adsorbs the new plate glass 5 The intermediate moving cylinder 34 being moved to the adjacent position of the suction position is moved directly below the cutout portion 26 that is the suction position of the glass sheet 5.

  Looking at the sheet glass turning and conveying process of the sheet glass conveying apparatus which is an embodiment of the present invention with such a configuration, when the sheet glass 5 is first conveyed to the work table 10 with the air floating part 20 activated, The suction unit 31 of the first suction transport unit 30 is activated and the suction plate 31 a is lifted to the bottom surface of the plate glass 5 and then sucked. At the same time, the suction belt 31 is transported in the length direction by the rotating belt 32.

  At this time, the other adsorber 31 disposed on the adjacent rotating belt 32 is moved to the front part for adsorbing the new glass plate 5 while the front adsorber 31 is advanced to the rear end of the length direction. After being moved and moved by the moving cylinder 34 to a position immediately below the cutout portion 26 that is the adsorption position of the plate glass 5, preparations for carrying the plate glass 5 newly carried are prepared.

  As described above, after one suction machine 31 transports the plate glass 5, the suction machine 31 of the adjacent rotating belt 32 moves to the front of the work table 10 and waits for transporting a new plate glass 5. The rotation motor of the rotating belt 32 can be automatically controlled so that the sheet glass 5 can be continuously conveyed while repeating the above.

  When the plate glass 5 is placed in the center of the work table 10 in this way, the suction turning machine 40 operates to lower the suction plate 41 to suck the upper surface of the plate glass 5 and then turn the plate glass 5 in the desired direction. Thereafter, the glass sheet 5 is adsorbed through the second adsorbing and conveying unit 50, and the conveying operation is performed so as to be discharged to the left as shown in FIG.

  On the other hand, the apparatus of the present invention can perform only the straight conveyance work of the plate glass 5 without operating the suction turning machine 40. At this time, the length of the plate glass 5 is absorbed by the rotating belt 32 while the suction machine 31 sucks the plate glass 5. Proceed in the direction.

  Here again, the other adsorbers 31 arranged on the adjacent rotating belt 32 move to the front part for adsorbing the new plate glass 5 while the adsorber 31 at the front part is advanced to the rear end part in the length direction. Then, after being moved by the moving cylinder 34 directly below the cut-out portion 26 that is the adsorption position of the plate glass 5, preparations for carrying the plate glass 5 newly conveyed are prepared.

  As described above, after one suction machine 31 transports the plate glass 5, the suction machine 31 of the adjacent rotating belt 32 moves to the front of the work table 10 and waits for transporting a new plate glass 5. It is possible to continuously convey the plate glass 5 while repeating continuously.

  In addition to the conveyance in the length direction, the plate glass 5 can be conveyed through the air floating portion 20 and the second suction conveyance unit 50 in the width direction through the above-described method.

  In addition to the regular linear conveyance in the length direction or the width direction, for example, the plate glass 5 is conveyed in the width direction through the second adsorption conveyance unit 50 and enters the position of the first adsorption conveyance unit 30. Then, since this 1st adsorption | suction conveyance part 30 attracts and it becomes possible also to convey the plate glass 5 in the length direction by which a direction changes at right angle, so-called direction change conveyance of the plate glass 5 is also possible.

  On the other hand, during the transfer operation, the amount of air supplied to the bottom surface of the plate glass 5 is increased due to an unexpected increase in the air discharge pressure, and a so-called swelling phenomenon occurs in which the central portion of the plate glass 5 swells upward. In order to prevent in advance, excessively supplied air is leaked to the bottom surface through the air leakage hole 21b at the center of the upper plate 21, while only the suction conveyance units 30 and 50 are in a state where the bottom surface of the plate glass 5 is floated by the control pressure of the appropriate pressure. Smooth transportation is possible using

  In this way, with the bottom surface of the plate glass 5 entering the work table 10 being floated by air, the plate glass 5 is adsorbed using the adsorbers 31 and 51 and the adsorption turning machine 40, and safely transported and turned. As a result, contact damage to the plate glass 5 generated during the rolling contact transportation of a conventional roller or the like does not occur at all, and the transportation can be performed quickly and smoothly and the work efficiency is generally improved. Of course, this can greatly improve the reliability of the product.

  As described above, the present invention has been described with reference to the above-described preferred embodiments. However, in addition to modifications in which such embodiments are simply applied in combination with conventional known techniques, the present invention is not limited to the claims and detailed description of the present invention. It goes without saying that all techniques that can be easily modified and used by those skilled in the art to which the present invention belongs are included in the technical scope of the present invention.
