Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a non-error angle step-back mechanism for a glass stacker. Background Art

[0002] There are many types of stacking equipment in flat glass production lines, among which flat gripping and vertical stacking equipment require a step-back mechanism to meet the stacking requirements of the glass. The step-back mechanism is usually arranged on the main machine or the pallet carrier. The present invention is mainly aimed at the pallet carrier with a step-back mechanism. At present, the advantages of this mechanism are simple structure and single movement, but the disadvantage is that it only has a single forward and backward function. When placing the glass in normal work, the angle between the suction cup frame and the backrest of the glass pallet must be fixed, otherwise it is easy to cause scratches on the glass surface. In actual production, the consistency of glass pallets of some manufacturers is poor. After the rack is replaced, there may be a deviation between the backrest of the new pallet and the set backrest. When the deviation exceeds 0.1%, it will become one of the reasons for the scratches on the bottom of the glass when placing the glass.

[0039] The tops of the first cross roller bearing 7 and the second cross roller bearing 8 are respectively fixedly arranged on both sides of the bottom of the moving platform 12 .

[0040] The left side moving pair 3 includes: two first wheels 3-2, a first bracket 3-3, and two first pins 3-4;

[0041] The bottom of the first bracket 3-3 has a first groove, and the first wheel 3-2 is rotatably disposed in the first groove through the first pin shaft 3-4;

[0042] The first bracket 3 - 3 is fixed to the inner ring of the first cross roller bearing 7 , and the bottom of the moving platform 12 is fixed to the outer ring of the first cross roller bearing 7 .

[0043] Wherein, the left side driving mechanism 5 comprises: a first reduction motor 5-1, a first gear 5-2, and a first rack 5-3;

[0044] The first reduction motor 5-1 is fixedly arranged on one side of the first bracket 3-3, the first rack 5-3 is fixedly arranged on the first fixed support 1, one side of the first gear 5-2 is fixedly connected to the rotating shaft of the first reduction motor 5-1, and the first gear 5-2 is meshed with the first rack 5-3;

[0046] The right side moving pair 4 includes: two second wheels 4-2, a second bracket 4-3, and two second pins 4-4;

[0047] The bottom of the second bracket 4-3 has a second groove, and the second wheel 4-2 is rotatably disposed in the second groove through the second pin shaft 4-4;

[0048] The two slide grooves 9-2 are fixedly arranged on the upper part of the second bracket 4-3, and the fixed bracket 11 is slidably arranged on the upper part of the second bracket 4-3 through the slider 9-1 and the slide groove 9-2;

[0055] When in use, when the distance measuring sensors 14 on both sides of the glass stacker suction cup frame detect that the position angle of the backrest of the glass container 13 placed on the moving platform 12 is offset, the left-side driving mechanism 5 and the right-side driving mechanism 6 can be driven to move forward or backward on the first guide rail 3-1 and the second guide rail 4-1, so as to adjust the angle of the moving platform 12 and correct the position angle of the backrest of the glass container 13; wherein, since the left-side driving mechanism 5 and the right-side driving mechanism 6 can be driven separately, the moving platform 12 can utilize the rotation of the first cross roller bearing 7 and the second cross roller bearing 8 during the process of moving forward and backward by using the left-side driving mechanism 5 and the right-side driving mechanism 6, so that the angle between the moving platform 12 and the first guide rail 3-1 and the second guide rail 4-1 changes, thereby adjusting the position angle of the backrest of the glass container 13, such as Figure 1 As shown, when the distance measuring sensor detects that L1 and L2 do not match the set value L, it only needs to drive the left driving mechanism 5 and / or the right driving mechanism 6 to make the distance between L3 and L4 change in reverse until L1=L2=L.

[0056] In summary, the present invention can automatically correct the consistency deviation of the backrest of the glass pallet and the position deviation when the pallet is placed on the support table, thereby reducing scratches on the bottom of the glass caused by improper placement when using the stacking equipment.
