Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts.

  The film coated trim glass can be recycled after the LCD glass substrate cutting process. FIG. 1 illustrates an exemplary embodiment of a glass recycling system 100 according to one or more embodiments. The glass recycling system 100 comprises a crusher system 102, a sorter system 104, a receiving system 106, and a film and dust collection system 108.

  The grinder system 102 grinds the film coated trim glass into a film coated cullet. The film coated cullet is then received by the sorter system 104 where the majority of the film is separated from the film coated cullet. The separated cullet is received by the receiving system 106 while the separated film is collected by the film and dust collection system 108. Alternatively, the film and debris recovery system 108 may be connected to the crusher system 102 and the sorter system 104, where some film and debris may be produced as described below.

  The crusher system 102 comprises a tilting device 200 and a crusher 300. FIG. 2 shows an exemplary embodiment of the tilting device 200. The film coated trim glass is introduced into a cart 404 (shown in FIG. 4a). After the cart 404 is moved to the cart weighing platform 202 to obtain the total weight (A), it is moved onto the tilter stage 204 so as to face the tilter board 206 and positioned. When positioning the cart on the tilter stage 204, two forks 208 and 210 extending from the tilter board 206 extend below the cart 404 (shown in FIG. 4a). A tilter motor 216 controls the tilter board 206 to move up and down. The safety fence 214 may have a lattice structure to prevent the unwanted access of any person or object.

  FIG. 3 shows an exemplary embodiment of a crusher 300. The input hopper cover 302 encloses and protects the feed port 402 (shown in FIG. 4 a) of the crusher 300. Below the input hopper cover 302 is connected a crusher housing 312, in which are located in-crusher 416 and 418 utilized to crush film-coated trim glass into film-coated cullet (see FIG. The in-mill crusher shaft 310 can be identified on one side of the crusher housing 312, as shown in FIG. 4a). A crusher motor 308 used to control the rotation of the crusher is connected to the other side of the crusher housing 312. A bridge breaker housing 304 is located on the input hopper cover 302 and protects one or more bridge breakers 408 (shown in FIG. 4 a) located inside the input hopper cover 302 and the bridge breaker shaft 306 Protruding from both sides of the bridge breaker housing 304 secures one or more bridge breakers 408. A crusher position sensor 314 is disposed in the crusher housing 312 to detect the current position of the in-crusher shaft 310. Further, to monitor if there is too much debris inside the crusher 300, eg, in the crusher 300, or if there is glass that can not be pushed into the crusher, the web camera 316 may be loaded with a hopper cover It may be located on 302 and connected to an LCD monitor (not shown).

  FIG. 4a shows a side view of a crusher system 102 comprising a tilting device 200 and a crusher 300 and its method of operation. As described above, the cart 404 containing the film coated trim glass is moved to the cart weighing platform 202 to obtain the total weight (A). The cart 404 is then moved onto the tilter stage 204 for positioning. In operating tilter 200, tilter motor 216 controls tilter board 206 to move upwardly with forks 208 and 210 extending from tilter board 206. The forks 208 and 210 together lift the cart 404 until it reaches the supply port 402 past the tilt shaft 212 (shown in FIG. 2). The board 206 with the cart 404 mounted thereon is tipped as the cart 405 shows to load the film coated trim glass 403 from the cart 405 into the crusher 300.

  The in-mill crushers 416 and 418 in the crusher housing 312 are film coated trim glass 403, for example, a film having a target average piece size of about 30 × 30 millimeters and a target maximum piece size of about 50 × 50 millimeters, for example. Grind into coated cullet 406. However, the size of the milled film-coated cullet should not be too small. This is because the smaller the shattered film-coated cullet, the easier it is to be sucked and carried away by the film and debris recovery system 108, thus reducing the recycling rate. The film covering the film-coated cullet 406 is also preferably broken into small pieces, separated from the cullet, and pre-sucked into the film and debris collection system 108.

  The one or more bridge breakers 408, which rotate around the bridge breaker shaft 306, promotes crushing by pushing the film coated trim glass 403 into the in-crushers 416 and 418. It should be understood that the one or more bridge breakers 408 are optional.

  The film coated cullet 406 falls onto the feeder 412 and is accumulated therein. Vibrator 410 vibrates feeder 412, causing film-coated cullet 406 to spring out of outlet 414 adjacent feeder 412 onto sorter 500, described in detail below.

  Further, after the film-coated trim glass 403 is loaded, the empty cart 404 is lowered by moving the forks 208 and 210 downward by the tilt motor 216. The empty cart 404 is then moved to the cart weighing platform 202 to obtain cart weight (B). Thus, the net weight of the film coated trim glass 403 can be calculated by subtracting the cart weight (B) from the total weight (A) for a subsequent inspection procedure.

  FIG. 4 b shows the in-crusher shredders 416 and 418 in the crusher housing 312. In the embodiment of FIG. 4b, the crushers 416 and 418 are each shown as having twelve claws made of blades, but any suitable number of claws may be applied, for example, depending on the size of the crusher. it can. In one embodiment, a plurality of in-mill crushers 416 and 418 repeatedly overlap one another to form an in-mill crusher set. In another embodiment, only one in-crusher crusher is disposed within crusher housing 312.

  FIG. 4c shows a bridge breaker 408 according to one or more embodiments described herein. Although the bridge breaker 408 is shown as jagged at one end, any shape suitable for pushing the film coated trim glass 403 into the bridge breaker 408 can be considered, and It can be easily understood that one or more bridge breakers 408 can be applied. At the other end of the bridge breaker 408 there is a hole 420 through which the bridge breaker shaft 306 can pivot about the bridge breaker shaft 306.

  The sorter system 104 may comprise a plurality of sorters 500. FIG. 5a shows the outside of the sorter 500 in one embodiment. The sorter 500 includes a case 501 covered by the lower cover 502 and the upper cover 504. The lower cover 502 and the upper cover 504 are fixed on the case 501 by a plurality of locks 532. The case 501 is supported by a plurality of springs 506 connected to a main frame 505 supported by a plurality of vibration isolators 514, 515 and 516. One or more counterweights 518 are used to balance the sorter 500.

  In this embodiment, the case 501 of the sorter 500 is inclined in the upward direction. The inlet 520 receives film-coated cullet and / or cullet from the outlet 414 of the grinder 300 or the outlet 530 of another sorter 500 below the case 401, and the outlet 530 is the film-coated cullet and / or cullet. Are discharged to the inlet 604 of the bucket elevator 602 or the inlet 520 of another sorter 500 above the case 401.

  The interior of the crusher 300 is monitored using two access doors 522 and 528 to determine, for example, whether there is too much debris in the sorter 500. The inspection doors 522 and 528 may be transparent and may be open. It can be easily understood that any number of inspection doors can be applied. Air enters the case 401 through the air inlet opening 526 and exits the case 401 through the film collection holes 524 and 525 to carry away the separated film as described in detail below.

  The lower motor 508 of the case 501 drives and rotates two eccentric cams 510 and 511 connected by a shaft (not shown), and these eccentric cams 510 and 511 rotate around the shaft. Eccentric cams 510 and 511 abut against springs 512 and 513 respectively, and springs 512 and 513 together abut against block 503 attached to the bottom of case 501.

  FIG. 5 b shows three non-flat plates 540, 542 and 544 placed in series inside the case 501 of the sorter 500. The non-flat plates 540, 542 and 544 may have serrated raised surfaces, ie the profiles of the non-flat plates 540, 542 and 544 may be serrated. The raised surfaces of the non-flat plates 540, 542 and 544 may also be at least one of: wavy; pleated; textured; stepped; The raised surfaces of the non-flat plates 540, 542 and 544 are illustrated as having equally spaced creases, but unequally spaced creases may be applied. Optionally, the raised surfaces of non-flat plates 540, 542 and 544 may be irregular. Further, non-flat plates 540, 542, and 544 may be removably connected to sorter 500 such that one or more non-flat plates 540, 542, and 544 may be independently cleaned or replaced. Although three non-flat plates 540, 542 and 544 are illustrated, any number of non-flat plates can be applied. Non-flat plates 540, 542 and 544 may be, for example, metals, alloys (eg carbon steel), or films from film-coated cullet when film-coated cullet hits non-flat plates 540, 542 and 544 as described below It may be made of any material having sufficient hardness to promote the separation of

  Referring again to FIG. 5a, when the sorter 500 is activated, the upper cover 502 and the lower cover 504 are closed and locked. Depending on the gearing configuration for driving the cam, in certain embodiments, the motor 508 may self-rotate at, for example, 60-120 rpm, such as about 100 rpm. Next, the motor 508 drives the two eccentric cams 510 and 511 to rotate at, for example, 0 to 1800 rpm via a frequency converter (not shown). Subsequently, the eccentric cams 510 and 511 cause the case 501 to reciprocate back and forth via the block 503 by repeatedly moving the springs 512 and 513 back and forth. The spring 506 generates vibrations of the case 501 and the non-flat plates 540, 542 and 544 therein by amplifying the movement of the entire case induced by the springs 512 and 513 to, for example, about 60-80 mm. In operation, vibration isolators 514, 515 and 516 function as a braking mechanism between sorter 500 and the ground.

  The film coated cullet and / or cullet enters the inlet 520 of the sorter 500 and falls onto the lower end of the non-flat plate 540. As the case 501 vibrates, the raised surfaces of the non-flat plates 540, 542, and 544 help the film-coated cullet and / or cullet bounce off the non-flat plates 540, 542, and 544. When the film-coated cullet falls on the non-flat plates 540, 542, and 544, the impact of the fall separates the film from the film-coated cullet, but these are pre-separated in the crusher 300 as described above. There is. The two intake pipes are connected at one end to the sorter 500 at the film collection holes 524 and 525 on the lower cover 502 and at the other end negative pressure in the case 501 and the dust collection system 108 Connected to the film to apply the Thus, the separated film in the case 501 is captured by suction and transferred to the film and dust collection system 108. It can be appreciated that any suitable number of film collection holes and pipes can be applied. The inspiratory air velocity is fine-tuned and balanced to reduce the rate of loss of cullet that results from the film and cullet captured by the debris collection system 108.

  By maintaining the vibration of the case 501, the separated film, separated cullet and film-coated cullet bounce and can be controlled as a function of the inclination of the non-flat plates 540, 542 and 544 and the rotational speed of the eccentric cam Advance (ie, climb) along the longitudinal direction of the case 50 at a speed of about 10 cm / sec. Since the specific gravity of the cullet and film is different, and the cullet is denser than the film, for example, the specific gravity of the cullet and film is about 2.383 and 0.9 respectively, the separated films are separated cullet and film-coated cullet A portion of the film that can be advanced faster than the separated film floats in the air, which tends to cause the separated film to be drawn by the pipe through the film recovery holes 524 and 525 compared to the separated cullet Is strong.

  It should be noted that when the film coated cullet reaches the outlet 530, the film may not be completely separated from the film coated cullet. In such a case, a plurality of sorters 500 may be arranged, ie the outlet 530 of one sorter may be located above the inlet 520 of another sorter, whereby the previous sorter If not separated, the film may be separated from the film coated cullet in a subsequent sorter.

  FIG. 5c shows another embodiment 560 of the sorter. The sorter 560 is arranged such that the non-flat plate of the sorter 560 is the descending step 564, ie the film coated cullet is received on the upper side of the sorter 560 and the film coated cullet and / or cullet is sorted It has the same structure and function as the sorter 500 except that it is discharged below the bowl 560, and comprises an eccentric cam 566 and springs 568, 570 and 572.

  The purpose of this step design is to assist the film-cullet separation by falling from the height of the step while the film-coated cullet moves forward along the longitudinal direction of the sorter 560. The sealing cover 562 at the top captures the film into the film and debris collection system 108 along with air intake while air enters the sorter 560 from a plurality of small holes on the step. As mentioned above, the separated film can be advanced faster than the separated cullet and the film-coated cullet, and part of the separated film floats in the air, whereby the separated film is separated It is more likely to be sucked by the sealing cover 562 compared to the cullet.

  Optionally, multiple obstacles (e.g., chains, baffles, etc.) can be placed on the steps to facilitate separation of the film from the film coated cullet. Specifically, the obstacle improves the cullet recycling rate by strengthening the impact to which the film-coated cullet is subjected. For example, the chain can be swung by vibration of sorter 560, thereby promoting film separation from film coated cullet. Multiple obstacles can be removably connected on one or more non-flat plates, which facilitates cleaning.

  FIG. 6 is a schematic view of a receiving system 600 comprising a bucket lift 602 and a receiving station 614. The inlet 604 of the bucket elevator 602 receives cullet and / or film coated cullet from the outlet 530 of another sorter 500. After receiving the cullet and / or the film-coated cullet, the bucket elevator 602 transfers the cullet and / or the film-coated cullet by the motor 608 through the outlet chute 610 of the bucket elevator 602 and the inlet 612 of the receiving station 614. , Transfer to the receiving station 614. Although the inspection door 606 is used to monitor the interior of the crusher, the inspection door 606 may be transparent and may be open. A cleaning door 624 can be located at the bottom of the bucket lift 602 to clean the interior of the bucket lift 602 if too much film and / or debris is accumulated. Preferably, the film and / or debris in the bucket lift 602 can also be aspirated with the film and debris collection system 108.

  When the receiving station 614 is collecting cullet and / or film-coated cullet, the receiving bucket (ie, raw material cullet hopper, not shown) having a capacity of about 1200 kg is floor-leveled with the opening facing upward Positioning on the vessel 622. The retractable cover 618 descends onto the receiving bucket to seal the opening of the receiving bucket, the sliding gate 620 on the retractable cover 618 is opened, and the cullet and / or the film-coated cullet is the receiving bucket It is discharged. When the target weight (ie weight set point) of the recovered cullet and / or film-coated cullet, as detected by floor scale 622, is reached, sliding gate 620 is closed and subsequently retractable cover 618 is opened. (Ie, lift the retractable cover 618). Next, the receiving bucket filled with the collected cullet and / or film-coated cullet is replaced with an empty receiving bucket. Thereafter, the retractable cover 618 is lowered to close the receiving bucket and the sliding gate 620 reopens. It should be noted that when the sliding gate 620 is closed, the bucket lift 602 can continue to transfer cullet and / or film coated cullet to the receiving station 614. In such a case, the cullet and / or film coated cullet accumulates on the closed sliding gate 620 and drops into the receiving bucket when the sliding gate 620 is reopened.

  After the receiving bucket filled with cullet and / or film coated cullet is removed from the receiving station 614, the weight of the cullet can be measured and the rate of recycling can be estimated. Acceptable, although at least some film-coated cullet may still be present in the recovered material, such as about 3% of the film-coated cullet in the recovered material (which corresponds to 97% film removal) The recycled material in the bucket is suitable for application to other manufacturing processes, such as the manufacture of glass sheets.

  It can be easily understood that the film removal rate increases as the number of sorters used in sorter system 104 increases, but at the same time the film and debris recovery without part of the separated cullet being collected in receiving system 106 Due to the fact that it is aspirated by the system 108, the recycling rate is expected to decrease.

  Turning to Figures 7a and 7b. The film and debris collection system 108 may comprise one or more films and debris collector 700. Preferably, by designing the plurality of films and debris collector 700 to operate alternately, the system continues to operate without interruption while the operator changes the bag. The film and debris collector 700 recovers the film debris generated from the sorter system 104 through the debris recovery inlet 722 into a bag disposed under the film and discharge gate 708 of the debris collector 700. The bag may, for example, be about 1 cubic meter in size and may for example be loaded with 200-300 kg. Preferably, the film and debris collector 700 may also recover film debris generated from the crusher system 102 and the receiving system 106.

  Motor 718 activates suction through pipe 716. A filter 720 (shown as 5 × 5) filters the film and / or debris that is drawn through the debris collection inlet 722. Both the compressed dry air buffer tank 712 and the reverse pulse spray 710 can be operated to supply compressed dry air from the inside of the debris collector housing 706 to the filter 720 to clean the film and / or debris deposited on the filter 720 . The filter 720 may be manually cleaned by unlocking the top cover 702. The film collected in the system can be automatically ejected to the bulk bag using the pulse injection system. The recovered film can be sold to a recycling company. Although the inspection door 714 is used to monitor the interior of the crusher, the inspection door 714 may be transparent and may be open.

  The following examples further illustrate various embodiments.

Example 1
In this embodiment, the sorter of FIGS. 5a and 5b is utilized. The loading amount of the inclination device 200 is 500 kg. The grinder 300 is 1 meter wide. The in-mill crushers 416 and 418 in the crusher 300 each have twelve claws made of blades. The rotation speed of the in-crusher 416 and 418 is 20 rpm. Three sorters are used in series in sorter system 104 to achieve a film removal rate of 97%. The overall system performance of this example is 800 kg / hour.

  The length of the sorter 500 is 1.2 m. A feature of the sorter 500 is that the case 401 is inclined in the upward direction at an angle of 25 ° to 35 °, preferably 30 ° from horizontal, whereby the film coated cullet is one or more non-flat plates 540, 542 And 544 below. The two eccentric cams 510 and 511 repeatedly move the springs 512 and 513 back and forth by about 50 mm, which is amplified by the spring 506 to about 50-70 mm, preferably 60 mm, and up to 80 mm.

  The raised surfaces of non-flat plates 540, 542 and 544 of sorter 500 have equally spaced wrinkles 550 separated by 10-20 mm. The height 548 of each crease is 5 mm, and the slope of the beveled edge 546 of each crease is 40-45 degrees with respect to the ground.

Example 2
In this embodiment, the classifier of FIG. 5c is used. The loading amount of the inclination device 200 is 800 kg. The crusher is 2 meters wide and the number of crushers is twice that of Example 1. Each in-crusher crusher in crusher 300 has six claws made of blades. The rotation speed of the crusher in the crusher is 50 rpm. Due to the large number of in-crushers and the high rotational speed, bridge crushers are not necessary in this embodiment. In this example, only one sorter is needed to achieve a film removal rate of 97%. The overall system performance of this example is 800 kg / hour.
