[0032] The on-line quick transfer and classification method of the glass tube on-line quick transfer and classification system includes the following working steps.

[0033] 1) In the initial state, as Figure 1 and Figure 5 shown, the first group of supporting protrusions of the inner group chain conveyor mechanism 1 is below the incoming pipe route of the incoming pipe conveying device 11, and the first group of supporting protrusions and the second group of supporting protrusions of the outer group chain conveyor mechanism 2 are on the conveying line of the incoming pipe conveying device 11;

[0034] 2) The outer group chain conveyor mechanism 2 and the incoming pipe conveying device 11 have the same rotation efficiency to gradually bring the incoming pipes of the incoming pipe conveying device 11 onto the supporting protrusions of the outer group chain conveyor mechanism 2;

[0035] 3) When the photoelectric switch 6 detects that all the supporting protrusions of the outer group chain conveyor mechanism 2 are carrying the glass tubes 5, it starts to move forward rapidly. At this time, the inner group chain conveyor mechanism 1 and the incoming tube conveying device 11 have the same rotation efficiency to continue receiving incoming tubes. During the period when the outer group chain conveyor mechanism 2 drives the glass tubes to move forward rapidly, the PLC determines whether the incoming tubes on the incoming tube conveying device 11 are type A tubes or type B tubes according to the information detected by the industrial camera 12. When the type A tubes move to the front of the pushing cylinder 7, the PLC controls the pushing cylinder 7 to act to push the type A tubes off the supporting protrusions of the outer group chain conveyor mechanism 2 one by one, so that they fall into the subsequent equipment, while the type B tubes fall onto the tube receiving and supporting plate 8 one by one when the supporting protrusions move to the bottom end of the conveying track;

[0036] 4) When the number of glass tubes on the tube receiving and supporting plate 8 reaches the preset number, if there are remaining glass tubes on the outer group chain conveyor mechanism 2, it stops operating. After the glass tubes on the tube receiving and supporting plate 8 are conveyed to the next working station, the outer group chain conveyor mechanism 2 operates again. When the type A tubes move to the front of the pushing cylinder 7, the PLC controls the pushing cylinder 7 to act to push the type A tubes off the supporting protrusions of the outer group chain conveyor mechanism 2 one by one, so that they fall into the subsequent equipment, and the glass tubes belonging to type B fall onto the tube receiving and supporting plate 8 when the supporting protrusions move to the bottom end of the conveying track. When there are no more glass tubes on the outer group chain conveyor mechanism 2, the outer group chain conveyor mechanism 2 moves rapidly below the incoming tube route to prepare to take over the inner group chain conveyor mechanism 1 to receive the glass tubes;

[0037] 5) In steps 3) and 4), the outer group chain conveyor mechanism (2) and the inner group chain conveyor mechanism (1) alternately repeat the actions of steps 3) and 4), and so on.

[0038] When the number of glass tubes on the tube receiving and supporting plate 8 reaches the preset number, the tube receiving and supporting plates 8 symmetrically arranged at both ends of the glass tubes move rapidly inward to tidy up the glass tubes on the tube receiving and supporting plate 8, and then move rapidly outward to make the glass tubes on the tube receiving and supporting plate 8 break away from the tube receiving and supporting plate and fall onto the first support plate 9. After that, the tube receiving and supporting plate 8 quickly returns to its original position to wait for receiving type B glass tubes.

[0039] The tube receiving and supporting plate 8 is connected to a radial displacement driving mechanism to drive the front-layer tube receiving plate to move radially, so that only one glass tube can fall onto the tube receiving and supporting plate 8 each time.

[0040] When the number of glass tubes on the first support plate 9 reaches the preset quantity, the first support plate 9 moves downward under the drive of the first support plate driving mechanism. At this time, the second support plate 10 moves backward, upward, and forward under the drive of the second support plate driving mechanism to move above the first support plate 9 to continue receiving the glass tubes falling from the tube receiving and supporting plate. At this time, the glass tubes on the first support plate 9 are bundled and then transferred out of the first support plate 9;

[0041] When the number of glass tubes on the second pallet 10 reaches the preset quantity, the second pallet 10 moves downward under the drive of the second pallet driving mechanism. At this time, the first pallet 9 moves backward, upward, and forward under the drive of the first pallet driving mechanism to move to the first pallet 9 to continue receiving the glass tubes that fall from the tube supporting pallet. At this time, the glass tubes on the second pallet 10 are bundled and then transferred out of the first pallet 10, and so on.

[0042] The utility model provides an on-line rapid transfer and classification system for glass tubes. For the double-channel structure design to adapt to the classification and transfer of two types of glass tubes, and at the same time for the design of a rapid transfer mechanism synchronized with the incoming tubes. The system includes an on-line rapid transfer device and a classification device. The inner group chain conveyor mechanism and the outer group chain conveyor mechanism in the on-line rapid transfer device act alternately to receive the incoming tubes to ensure the continuous operation of the equipment. The PLC judges whether the glass tube is type A or type B according to the current glass tube detection result transmitted from the front, and controls the rapid action of the push cylinder of the classification device to push the type A glass tubes from the on-line rapid transfer device into the type A tube collection mechanism. If the current glass tube detection result belongs to type B, the glass tube enters the type B tube collection device under the drive of the on-line rapid transfer device.

[0043] The utility model provides an on-line rapid transfer and classification system for glass tubes, which can further subdivide the cut glass tubes. Based on the re-detection of this type of glass tubes, the glass tubes are subdivided into multiple grades. The utility model is aimed at the traditional glass drawing production line for large-scale application, and can be directly connected to the incoming tube conveying equipment, enabling enterprises to realize the on-line subdivision and packaging of qualified glass tubes with only a low transformation cost without large-scale equipment renovation and update, so as to select the best from the good, which has great advantages.
