When (S28) not having glue in prompting the 3rd de-bubble bucket, open the first de-bubble bucket and to following gluing mechanism glue is provided, the glue behind the controlled filter continues to carry out de-bubble in the injection second de-bubble bucket;
When (S29) glue in the prompting second de-bubble bucket was full, circulation was carried out above-mentioned steps (23)-(28) and is accomplished until work.
Below in conjunction with Fig. 5-Fig. 8; Glue supply method to using glue feedway 1 of the present invention is elaborated; After system starts working; Whether the 5th sensor 101a in the inspection recycling bin 10 has signal earlier, if there is the glue of then explaining in the recycling bin 10 full, then earlier the glue vacuum in the recycling bin 10 is sucked filter vat 30 inner filtrations; Do not have glue in it if the 5th sensor 101b in the recycling bin 10 has signal then to explain, then extract the glue in the Raw material pail 20; Glue vacuum in recycling bin 10 or the Raw material pail 20 are sucked carry out filtration first time in first filter vat 31; The glue filtrator of glue in it filters the back and sucked by vacuum and carry out the filtration second time in second filter vat 32; In second filter vat 32, after the glue filtrator filters, sucked in the 3rd filter vat 33 and filter for the third time by vacuum; After glue filtrator in the 3rd filter vat 33 filters, after waiting for de-bubble, uses by the protection glue that obtains clean.
Then; Open first combination valve 411 and the solenoid valve 413 at vacuum gas port place at the glue-feeder place of the first de-bubble bucket 41, pumped vacuum systems vacuumizes processing to the first de-bubble bucket, 41 inside, and first mozzle 415 of glue through the glue-feeder place drains in the first de-bubble bucket 41; First mozzle 415 can separate protection glue body particle as much as possible; Constantly eliminate the bubble that wraps up between the glue particle in the process that glue in the first de-bubble bucket 41 rises under the condition of vacuumizing, when first sensor 416a sends the signal that detects glue, add full glue in the first de-bubble bucket 41; First combination valve 411 that close the glue-feeder place this moment stops to add glue; Close the solenoid valve 413 at vacuum gas port place again after waiting for certain hour, and open the solenoid valve 412 at compression gas port place and first combination valve 414 at gum outlet place, in the first de-bubble bucket 41, feed pressurized air; With being transported to down gluing mechanism 50 after the extrusion of the glue in it; In the process that glue is forced out, its residual bubble is further removed, and then obtains the protection glue that accords with production requires; In the first de-bubble bucket 41 glue add full in; Open second combination valve 421 and the solenoid valve 423 at vacuum gas port place at the glue-feeder place of the second de-bubble bucket 42, the glue after filtering is added in the second de-bubble bucket 42 carry out de-bubble, in the process of adding, glue is carried out de-bubble; When the second sensor 426a detects glue; Glue in the second de-bubble bucket 42 adds full, and second combination valve 421 that close the glue-feeder place this moment stops in it, to add glue; Still, constantly eliminate the bubble in the glue to vacuumizing processing in the second de-bubble bucket 42; In the second de-bubble bucket 42 glue add full in; Open the 3rd combination valve 431 and the solenoid valve 433 at vacuum gas port place at the glue-feeder place of the 3rd de-bubble bucket 43; Glue after filtering sucked in the 3rd de-bubble bucket 43 carry out de-bubble; In the process of adding, glue is carried out de-bubble, gluing mechanism 50 used under meanwhile the glue in the first de-bubble bucket 41 continued to supply with; When first sensor 416b sends signal; Glue in the first de-bubble bucket 41 is all exported; The solenoid valve 423 that close the vacuum gas port place of the second de-bubble bucket 42 this moment; And open the solenoid valve 422 at compression gas port place and second combination valve 424 at gum outlet place, to the second de-bubble bucket 42 in, feed pressurized air, with the extrusion of the glue in it and be transported to down gluing mechanism 50 for use; Still injecting glue in the 3rd de-bubble bucket 43 this moment, do not have glue and wait to add glue in the first de-bubble bucket 41 next time; When the 3rd sensor 436a sends the signal that detects glue; Glue in the 3rd de-bubble bucket 43 adds full, and the 3rd combination valve 431 that close the glue-feeder place this moment stops in it, to add glue; But still to vacuumizing processing in the 3rd de-bubble bucket 43; With the bubble in the continuous elimination glue, gluing mechanism 50 uses under the glue sustainable supply in the second de-bubble bucket 42, restarts the glue after filtering is injected in the first de-bubble bucket 41 and carries out de-bubble; When the second sensor 426b sends signal; Glue in the second de-bubble bucket 42 is exported fully, and close the solenoid valve 433 at the vacuum gas port place of the 3rd de-bubble bucket 43 this moment, and opens the solenoid valve 432 at compression gas port place and the 3rd combination valve 434 at gum outlet place; In the 3rd de-bubble bucket 42, feed pressurized air; With the glue pressure place in it and be transported to down gluing mechanism 50, this moment, the first de-bubble bucket 41 still added glue, and the second de-bubble bucket 42 empties to wait for and adds glue next time; When filling it up with glue once more in the first de-bubble bucket 41, stop in it, to add glue, the glue after will filtering simultaneously injects in the second de-bubble bucket 42 and carries out de-bubble, and the 3rd de-bubble bucket 43 continues to following gluing mechanism glue to be provided; When the glue of the 3rd de-bubble bucket 43 all extrudes, open 41 pairs of following gluing mechanisms of the first de-bubble bucket again glue is provided, and the glue behind the controlled filter continues to carry out de-bubble in the injection second de-bubble bucket 42; When adding full glue in the second de-bubble bucket 42 once more, the glue after filtering injected in the 3rd de-bubble bucket 43 carry out de-bubble, control the first de-bubble bucket 41 and continue glue to be provided gluing mechanism down; Three de-bubble buckets so recycle; The memory space of protection glue is increased greatly,, and pass through control the interpolation protection glue time and the extrusion protection glue time of three de-bubble buckets with the satisfied needs that continue production; Strengthen the de-bubble effect, make the protection glue after the de-bubble satisfy the needs that Blu-ray Disc is produced.
Because glue feedway 1 of the present invention comprises recycling bin 10, Raw material pail 20, filter vat 30 and de-bubble bucket 40, de-bubble bucket 40 and comprises the three first de-bubble bucket 41, the second de-bubble bucket 42, the 3rd de-bubble buckets 43 that are set up in parallel; The upper end of first, second, third de-bubble bucket 41,42,43 all has vacuum gas port, compression gas port and glue-feeder; The lower end of first, second, third de-bubble bucket 41,42,43 all has gum outlet; Said vacuum gas port is communicated with pumped vacuum systems, and said compression gas port is communicated with compressed air system, and said glue-feeder is communicated with filter vat 30 sealings; Said gum outlet is communicated with said 50 sealings of gluing mechanism down; Be respectively arranged with mozzle 415,425,435 in the first, second, third de-bubble bucket 41,42,43, an end of mozzle 415,425,435 is connected in said glue-feeder place, and the other end of said mozzle 415,425,435 extends to de-bubble bucket 41,42,43 bottoms; Protection glue is sucked by vacuum and flows in the first, second, third de-bubble bucket 41,42,43 through mozzle 415,425,435 respectively; Mozzle 415,425,435 can separate the liquid particles of protecting glue, get in the first, second, third de-bubble bucket 41,42,43 glue rise the vacuum system effect under or the process of decline under the pressurized air effect in, can eliminate the bubble that wraps up between the glue particle effectively; To satisfy the needs that Blu-ray Disc is produced; Have higher de-bubble effect, and at least two de-bubble bucket periodic duties, protection glue memory space increased.
The above disclosed the preferred embodiments of the present invention that are merely can not limit the present invention's interest field certainly with this, so according to the equivalent variations that claim of the present invention is done, still belong to the scope that the present invention is contained.
