Description

Technical Field

[0001] The utility model relates to the technical field of cutting float glass, in particular to a cutting device for cutting the edge of an extra-long float glass. Background Art

[0002] When producing extra-long glass, the edges are broken off on a roller conveyor using a roller press. The broken edges then fall into the cullet bin for recycling. However, the edge cleaner and cullet bin are already installed during glass production. When producing extra-long float glass that exceeds the cullet bin, the length (S) of the cut glass edge will be longer than the length (L) of the cullet bin below the edge cleaner. After cutting, the glass edges are too long to fall directly into the cullet bin.

[0003] Now the production line cannot be stopped for modification to expand the length of the glass silo. In this way, the production of ultra-long glass is limited by the maximum clearing length of the cullet silo, and it is impossible to produce glass longer than the length specification of the cullet silo. Utility Model Content

[0004] The utility model provides a cutting device for cutting the edge of extra-long float glass, which can provide a hardware basis for producing glass with a length greater than the length specification of the cullet bin without modifying the length of the cullet bin.

[0005] In order to solve the above technical problems, the utility model provides a cutting device for cutting the edges of extra-long float glass, comprising a glass transport module and a cullet silo with a length of L, the cullet silo being arranged downstream of the glass transport module, a bending device being arranged on the glass transport module for breaking the edges of the glass on both sides, and an edge cutting device being arranged downstream of the bending device; two sensing devices with a distance of L being arranged on the same side of the glass transport module for detecting whether the length of the glass is greater than L, the sensing devices being arranged upstream of the edge cutting device;

[0006] When the sensing device senses the glass at the same time, the edge cutting device cuts the broken glass edge along the width direction of the glass, and the length of the glass edge formed by cutting is less than L.

[0007] In some embodiments, the edge cutting device includes a crossbeam and a column supporting the crossbeam, and the crossbeam is mounted above the glass transport module; cutting components are respectively provided at both ends of the crossbeam to cut the edges of both sides of the glass.

[0008] In some embodiments, the method further includes a lifting device and a conveying device that drives the lifting device to move along the beam; the cutting component is arranged below the lifting device and drives the cutting component to move up and down.

[0009] In some embodiments, guide rails connected to the lifting device are further provided on the upper and lower sides of the crossbeam, and the lifting device moves along the guide rails driven by the transmission device.

[0010] In some embodiments, the transmission device includes a drive motor and a synchronous conveyor belt. The drive motor is arranged at one end of the beam, and the synchronous conveyor belt is arranged inside the beam and is driven by the drive motor to transmit along the length direction of the beam.

[0011] In some embodiments, the cutting component includes a cutter wheel and a cutter head, and the cutter wheel drives the cutter head to rotate for cutting.

[0012] In some embodiments, the crossbeam includes a middle crossbeam and two side crossbeams, the middle crossbeam is perpendicular to the traveling direction of the glass, and the two side crossbeams have an inclination angle inclined toward upstream compared to the middle crossbeam.

[0013] In some embodiments, the inclination angle ranges from 14° to 18°.

[0014] In some embodiments, the sensing device is a photoelectric switch.

[0015] In order to solve the above technical problems, the present invention provides a cutting method for the cutting device for cutting the edge of ultra-long float glass, comprising the following steps:

[0016] Step 1: Determine whether the sensing device can sense the glass at the same time. If not, directly transmit the glass edge to the broken glass bin; if it can be sensed, proceed to step 2;

[0017] Step 2: Collect the rising edge signal of the photoelectric switch and the real-time speed of the glass conveying module to calculate the real-time position of the glass; when the glass moves to the cutting position, the edge cutting device cuts the edge at least once along the width direction, so that the length of the cut edge is less than L.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The utility model arranges an edge cutting device downstream of the edge breaking device and two sensing devices upstream of the edge cutting device, each at a distance equal to the length of the cullet bin, on one side of the glass transport module. When the sensing devices simultaneously sense glass, the edge cutting devices are activated to cut the broken edges along the width direction, so that the length of the cut edges is less than the length of the cullet bin and can fall smoothly into the cullet bin. Therefore, it is possible to produce glass with a length greater than the cullet bin length without having to modify the cullet bin length. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Reference Figure 1-5 This embodiment provides a cutting device for cutting the edges of extra-long float glass, comprising a glass transport module 1 and a cullet silo 7 with a length L of 4 meters. The cullet silo 7 is located downstream of the glass transport module 1. The glass transport module 1 is further provided with a rolling and bending device 3 for breaking the edges of the glass 5 on both sides in the width direction. The bent edges of the glass are transported to the cullet silo 7 by the glass transport module 1. In order to allow the edges of glass 5 longer than 4 meters to fall into the cullet silo 7, in this embodiment, an edge cutting device 4 is provided downstream of the rolling and bending device 3. Two photoelectric switches 2 are provided upstream of the edge cutting device 4, each 4 meters apart, as sensing devices. The photoelectric switches 2 are IFT206, PNP type, with a sensing distance of 4 mm. The two photoelectric switches 2 are provided on the same side of the glass transport module 1.

[0031] When the two photoelectric switches 2 do not sense the glass 5 at the same time, the length of the transported glass 5 is less than 4 meters, and the edge can fall directly into the broken glass silo 7. When the two photoelectric switches 2 sense the glass 5 at the same time, the length of the transported glass 5 is greater than 4 meters. At this time, the edge cutting device 4 cuts the broken glass edge along the width direction of the glass, so that the length of the glass edge formed by cutting is less than 4 meters, and it can fall smoothly into the broken glass silo 7.

[0032] Specifically, the edge cutting device 5 includes a crossbeam and columns 49 supporting the crossbeam. The columns 49 are located on both sides of the glass transport module 1, and the crossbeam is mounted above the glass transport module 1. Servo motors 43 (model 1FK7042-2AC71-1PA0, 0.75kW) are installed at both ends of the crossbeam. A synchronous conveyor belt 44 is installed inside the crossbeam along its length, linked to the servo motor 43. Driven by the servo motor, the synchronous conveyor belt 44 is driven along the length of the crossbeam (i.e., the width of the glass).

[0033] The servo motor 43 and the synchronous conveyor belt 44 together form a transmission mechanism. A cylinder 45, acting as a lifting mechanism, is connected to the synchronous conveyor belt 44. Driven by the transmission mechanism, the cylinder 45 moves along the length of the beam. Below the cylinder 45 is a cutting assembly comprising a cutter wheel 46 and a cutter head 47. Driven by the cutter wheel 46, the cutter head 47 rotates to cut the edges of the glass 5. The cutter head 47 is made of alloy steel with a diameter of 6.5 mm; the cutter wheel 46 has a polyurethane outer ring with a diameter of 60 mm. The cylinder input pressure must be within the range of 0.35 to 0.45 MPa.

[0034] The edge cutting device of this embodiment first determines whether the glass 5 transported by the glass transport module 1 exceeds 4 meters by using two photoelectric switches 2 installed upstream of the edge cutting device 4 at a distance of 4 meters. When only one of the two photoelectric switches 2 is on, it means that the glass 5 is less than 4 meters and no cutting action is required. When both photoelectric switches 2 are on at the same time, the glass 5 is greater than 4 meters and needs to be cut. The system calculates the real-time position of the glass 5 based on the collected rising edge signals of the photoelectric switches and the real-time speed of the roller 11 of the glass transport module 1. When the glass 5 is transported to the edge cutting position, the edge cutting device 4 drives the synchronous conveyor 44 to move via the servo motor 43, thereby driving the cylinder 45 to move along the crossbeam to the set edge cutting position. The cylinder 45 lowers the cutter head 47 and the cutter wheel 46 to cut the edge of the glass formed after the edge breaking at least once, so that the length of the cut glass edge is less than 4 meters and can fall smoothly into the broken glass silo 7.

[0035] Specifically, when the glass 5 is greater than 4 meters and less than 6 meters, the system will perform two cutting operations. When the glass 5 is greater than 6 meters, the system will perform three cutting operations. The length L of the cullet bin 7 can be other lengths and is not limited to this embodiment. The number of cutting operations performed by the system is also not limited to this embodiment, as long as the edge can be cut to a length smaller than the cullet bin length 7.

[0036] In order to ensure that the cutting wheel 46 and the cylinder 45 can operate stably and reduce the deviation in cutting accuracy caused by shaking, in this embodiment, guide rails 48 connected to the cylinder 45 are further provided on the upper and lower sides of the beam, and the cylinder 45 moves along the guide rails 48 driven by the transmission device.

[0037] Since the glass 5 is constantly moving forward on the roller conveyor, if the moving direction of the cutting component is parallel to the roller conveyor 11, the cutting marks on the glass 5 will be at an angle, and the glass 5 cannot be cut flat. Therefore, in order to cut the glass 5 flat, in this embodiment, the crossbeams include a middle crossbeam 42 and two side crossbeams 41. The middle crossbeam 42 is perpendicular to the moving direction of the glass 5 (i.e., parallel to the roller conveyor 11), and the two side crossbeams 41 have an upstream inclination of 14°-18° compared to the middle crossbeam 42. The conveying device is provided on the two side crossbeams 41, and the cutting component moves along the two side crossbeams 41, so that the cutting component can form an angle with the roller conveyor 11, so that the glass 5 is cut flat.

[0038] The specific implementation methods are as follows:

[0039] Step 1: Determine whether the photoelectric switch 2 can sense the glass 5 at the same time. If it cannot sense the glass 5, it means that the glass 5 is less than 4 meters, and the edge of the glass is directly transferred to the broken glass bin 7. If it senses the glass 5, it means that the glass 5 is more than 4 meters, and the edge cutting action in step 2 needs to be performed.

[0040] Step 2: Collect the rising edge signal of the photoelectric switch and the real-time speed of the glass conveying module 1, calculate the number of meters the glass 5 has advanced, and thus calculate the real-time position of the glass 5;

[0041] When the glass 5 reaches the starting position for cutting, the cylinder 45 lowers the cutter head 47, which then moves along the two side beams 41 under the drive mechanism, cutting the edge at least once along the width direction, ensuring that the length of the cut edge is less than L. When the glass 5 reaches the target position for cutting, the cylinder 45 actuates, raising the cutter head 47, completing the cutting process. The cut glass edge can then fall into the cullet bin, and the finished glass sheet undergoes edge cleaning by the edge cleaning machine 6 downstream.

[0042] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
