Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass stacking, in particular to a flat glass double-grab patching process. BACKGROUND

[0002] The single-grab process is usually used in the vertical stacking of the float glass production line, that is, only one glass plate can be grabbed in one grabbing action. With the continuous improvement of production process technology, especially in the grabbing of small and medium-sized glass plates, the double-grab process has gradually become the mainstream, that is, two glass plates can be grabbed in one grabbing action. The double-grab process has obvious advantages, that is, two glass plates can be grabbed at a time, greatly improving the production efficiency. However, the double-grab process also has its problems that must be overcome. Before the glass plates are grabbed by the double-grab process, the patching process must be performed. If the double-grab process is used for production, it must be ensured that the glass plates fed to the stacker each time are two glass plates in pairs. Due to various unexpected situations, such as falling plates, it cannot be ensured that the glass plates fed during production are in pairs. Therefore, the single-falling glass plates must be paired to ensure that the output glass plates after patching are two glass plates in pairs. SUMMARY

[0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present application is to provide a flat glass double-grab patching process capable of pairing single-falling glass plates.

[0004] To achieve the above-mentioned purposes and other related purposes, the present application provides a flat glass double-grab patching process using a flat glass double-grab patching device, which comprises: a lifting and translating device, and two roller device arranged in parallel;

[0005] Each roller device comprises an upstream roller and a downstream roller arranged in sequence, and the glass plate is conveyed from the upstream roller to the downstream roller. The lifting and translating device comprises a translating mechanism and a lifting mechanism connected with the translating mechanism. The lifting and translating device is arranged below the downstream rollers of the two roller devices, and the lifting mechanism can drive the translating mechanism to move above the downstream rollers of the two roller devices. The direction in which the translating mechanism drives the glass plate to move is perpendicular to the direction in which the roller device conveys the glass plate to move.

[0006] The flat glass double-grab patching process comprises the following steps:

[0007] 1) determining whether the same side of the roller equipment is non-continuous lack of glass plate or the same side of the roller equipment is continuous lack of glass plate; when one of the two roller equipment is not continuous lack of two glass plates, step 2) is performed; when one of the two roller equipment is continuous lack of two glass plates, step 3) is performed; the roller equipment which lacks glass plate in the two roller equipment is lack of glass roller, and the roller equipment which does not lack glass plate in the two roller equipment is ready glass roller;

[0008] 2) when the downstream roller of the ready glass roller has glass plate, the downstream roller of the lack of glass roller lacks glass plate, and the upstream roller of the ready glass roller has glass plate, the upstream roller of the ready glass roller and the downstream roller of the ready glass roller stop, the lack of glass roller drives the glass plate on the upstream roller of the lack of glass roller to move to the downstream roller of the lack of glass roller, at this time, the glass plate on the downstream roller of the lack of glass roller and the glass plate on the downstream roller of the ready glass roller form a pair;

[0009] 3) when the downstream roller of the ready glass roller has glass plate, the upstream roller of the ready glass roller has glass plate, and the upstream roller of the lack of glass roller lacks glass plate, the downstream roller of the lack of glass roller lacks glass plate, the ready glass roller and the lack of glass roller stop, the lifting mechanism drives the translation mechanism to move above the downstream roller of the two roller equipment, after the translation mechanism drives the glass plate on the downstream roller of the ready glass roller to move directly above the downstream roller of the lack of glass roller, the lifting mechanism drives the translation mechanism to move below the downstream roller of the two roller equipment, so that the glass plate on the translation mechanism is placed on the downstream roller of the lack of glass roller; then, the ready glass roller drives the glass plate on the upstream roller of the ready glass roller to move to the downstream roller of the ready glass roller, at this time, the glass plate on the downstream roller of the lack of glass roller and the glass plate on the downstream roller of the ready glass roller form a pair.

[0010] Preferably, the flat glass double-grabbing patch equipment further comprises a controller, which acquires information of lack of glass on the roller equipment to determine whether the same side of the roller equipment is non-continuous lack of glass plate or the same side of the roller equipment is continuous lack of glass plate; the lifting and translation equipment and the two roller equipment are connected with the controller.

[0011] Preferably, the translation mechanism is a belt transmission mechanism or a roller transmission mechanism.

[0012] As described above, the flat glass double-grab patching process of the present application has the following beneficial effects: the flat glass double-grab patching process can effectively inhibit the scratching of the upper surface of the glass plate, and no mark is left on the upper surface of the glass plate after the patching is completed; and the flat glass double-grab patching process is a fast, reliable and fully automatic patching process.

[0038] Each roller device comprises an upstream roller and a downstream roller arranged in sequence, and the glass plate 300 is conveyed from the upstream roller to the downstream roller, and the glass plates 300 conveyed on the two roller devices are one-to-one corresponding; the lifting and translating device 200 comprises a translating mechanism 210 and a lifting mechanism 220 connected with the translating mechanism 210, the lifting and translating device 200 is arranged below the downstream rollers of the two roller devices, and the lifting mechanism 220 can drive the translating mechanism 210 to move above the downstream rollers of the two roller devices; the direction in which the translating mechanism 210 drives the glass plate 300 to move is perpendicular to the direction in which the roller device conveys the glass plate 300 to move; the direction in which the glass plate 300 is conveyed from the upstream roller to the downstream roller is A in the figure Figure 1

[0039] The flat glass double-grab patching process comprises the following steps:

[0040] 1) Determine whether the roller devices are the same side non-continuous glass plate 300 or the same side continuous glass plate 300; when one of the two roller devices is not continuously absent of two glass plates 300, the roller devices are the same side non-continuous glass plate 300, and step 2) is performed; when one of the two roller devices is continuously absent of two glass plates 300, the roller devices are the same side continuous glass plate 300, and step 3) is performed; the roller device in which the glass plate 300 is absent in the two roller devices is the glass-absent roller 120, and the roller device in which the glass plate 300 is not absent in the two roller devices is the glass-complete roller 110;

[0041] ​2) When there is a glass plate 300 on the downstream roller 112 of the full glass roller, there is no glass plate 300 on the downstream roller 122 of the glass deficient roller, and there is a glass plate 300 on the upstream roller 111 of the full glass roller, and there is a glass plate 300 on the upstream roller 121 of the glass deficient roller, the upstream roller 111 of the full glass roller and the downstream roller 112 of the full glass roller stop, the glass plate 300 on the upstream roller 111 of the full glass roller is in a waiting state, the glass plate 300 on the upstream roller 121 of the glass deficient roller is driven by the glass deficient roller 120 to move to the downstream roller 122 of the glass deficient roller, at this time, the glass plate 300 on the downstream roller 122 of the glass deficient roller and the glass plate 300 on the downstream roller 112 of the full glass roller form a pair; the two glass plates 300 forming a pair are transported downstream together for double-grabbing mode stacking;

[0042] 3) When there is a glass plate 300 on the downstream roller 112 of the full glass roller, there is a glass plate 300 on the upstream roller 111 of the full glass roller, and there is no glass plate 300 on the upstream roller 121 of the glass deficient roller, and there is no glass plate 300 on the downstream roller 122 of the glass deficient roller, the full glass roller 110 and the glass deficient roller 120 stop, the translation mechanism 210 is driven by the lifting mechanism 220 to move above the downstream rollers of the two roller devices, the glass plate 300 on the downstream roller 112 of the full glass roller is supported by the translation mechanism 210, after the glass plate 300 on the downstream roller 112 of the full glass roller is driven by the translation mechanism 210 to move directly above the downstream roller 122 of the glass deficient roller, the lifting mechanism 220 drives the translation mechanism 210 to move below the downstream rollers of the two roller devices, so that the glass plate 300 on the translation mechanism 210 is placed on the downstream roller 122 of the glass deficient roller; then, the glass plate 300 on the upstream roller 111 of the full glass roller is driven by the full glass roller 110 to move to the downstream roller 112 of the full glass roller, at this time, the glass plate 300 on the downstream roller 122 of the glass deficient roller and the glass plate 300 on the downstream roller 112 of the full glass roller form a pair; the two glass plates 300 forming a pair are transported downstream together for double-grabbing mode stacking.

Compared with the prior art patching method of adsorbing the upper surface of the glass plate by the suction cup, the flat glass double-grab patching process can effectively prevent the upper surface of the glass plate 300 from being scratched, and the upper surface of the glass plate 300, that is, the air side of the glass, is not left any suction cup marks after the patching is completed.

[0044] The flat glass double-grab patching process can complete the entire patching process within 6 seconds, and this patching process does not occupy any time of other processes; for the entire production line, although the patching process is added, it does not occupy any production time. Therefore, the entire patching process is fast and efficient. The flat glass double-grab patching process is a fast, reliable, and fully automatic patching process.

[0045] The flat glass double-grab patching device further includes a controller, which acquires information about the lack of glass on the roller device to determine whether the roller device is a same-side non-continuous lack of glass plate 300 or a same-side continuous lack of glass plate 300; the lifting and translating device 200 and the two roller devices are connected to the controller. The controller controls the operation and stop of the lifting and translating device 200 and the two roller devices according to the acquired information about the lack of glass on the roller device, so that the flat glass double-grab patching is fully automatically controlled.

[0046] The translating mechanism 210 is a belt transmission mechanism. The upstream roller and the downstream roller have the same structure, and both the upstream roller and the downstream roller include a plurality of rotatable rollers.
