Description

Technical Field

[0001] The utility model belongs to the technical field of glass bending, and in particular relates to a piece taking device and a production line for hard-axis reverse-bending glass. Background Art

[0002] Curved glass is widely used in the fields of architecture, home appliances and automobiles. When making hard-axis reverse-bend glass, the glass is usually bent downward on the hard-axis bending equipment, that is, bent into a "︵" shape. Since hard-axis reverse-bend glass bends downward, direct transportation will cause the reverse-bend glass to fall into the gap between the lower forming rollers, so hard-axis reverse-bend glass cannot be directly unloaded from the rollers.

[0003] For example, the unloading device for rigid-axis reverse-bending glass of patent application number CN202323027916.X can realize automatic unloading of rigid-axis reverse-bending glass, but it is arranged on the side of the glass bending production line perpendicular to the glass conveying direction. After taking the glass, the entire unloading device moves outward to drive the reverse-bending glass to completely exit the rigid-axis reverse-bending forming equipment before stacking the glass. The entire unloading process is relatively cumbersome, inefficient, and has a low degree of automation and occupies a large area. Usually, in order to maximize the use of production plants, glass manufacturers will set up multiple side-by-side glass production lines, resulting in the side of each glass production line not having the installation and operation space for the unloading device of the above patent. Moreover, the unloading device of the above patent uses a rotating method to realize the lifting and lowering of the grabbing assembly. When the grabbing glass is rotated and lifted, the glass and the grabbing assembly shake greatly, which can easily cause the glass to be bumped. Summary of the invention

After the suction cups suck the glass, the rotating mechanism can drive the glass to rotate by a certain angle through its movement, so that both sides of the glass do not fall into the roller gaps of the conveying mechanism, and then the glass is placed on the conveying mechanism and directly conveyed out. In addition, by dividing the sheet taking bracket into two brackets and arranging two slide rails, the overall length after the sheet taking bracket is retracted can be shortened, thereby shortening the total length of the sheet taking device and further reducing the floor area.

Detailed implementation manners

[0033] The following will further elaborate on the present invention in conjunction with the drawings and embodiments, but it shall not be used as a basis for any limitation to the present invention. Embodiment

[0034] As Figure 1 shown, a hard-axis reverse-bending sheet-taking device 104 is arranged behind the hard-axis bending equipment 103 in the glass conveying direction, and the center line of the sheet-taking device 104 is parallel to the center line of the hard-axis bending equipment 103. The center line is as Figure 1 shown, and its direction is the same as the glass conveying direction. With such a setting, the center line of the sheet-taking device 104 is the same as the glass conveying direction, that is, the entire glass production line is in a straight line, occupying a small area.

[0035] As Figure 2As shown in the figure, the sheet taking device 104 includes a frame 1, a lifting bracket 2, a sheet taking assembly 3 and a conveying mechanism 4. The conveying mechanism 4 is arranged at the lower part of the frame 1 and is used for conveying the bent glass 5. The conveying mechanism 4 is a conventional glass conveying mechanism, such as a roller path with chain drive, which will not be elaborated here. A lifting guide 11 is arranged on the frame 1. Preferably, the lifting guide 11 is arranged on the longitudinal beams at the four corners of the frame 1. In other embodiments, the lifting guide 11 can be arranged at other positions on the frame 1. The lifting bracket 2 is arranged at the upper part of the frame 1 and is slidably connected with the lifting guide 11, and can be lifted up and down along the lifting guide 11. In this embodiment, the lifting guide 11 is a lifting slide rail. In other embodiments, the lifting guide 11 can be other parts such as a lifting chute or a lifting guide rod, as long as it can guide the lifting bracket 2 to lift vertically.

[0036] It should be noted that in this embodiment, the frame 1 of the hard shaft bending sheet taking device 104 is an independent frame, and the sheet taking device 104 can also share a frame with the hard shaft bending device 103.

[0037] The sheet taking assembly 3 is connected with the lifting bracket 2 and can slide back and forth along the glass conveying direction. The sheet taking of the bent glass 5 is realized by the up and down lifting of the lifting bracket 2 and the back and forth sliding of the sheet taking assembly 3, with stable structure, high automation degree and high sheet taking efficiency.

[0038] The sheet taking assembly 3 includes a sheet taking bracket 31, a suction cup bracket 32 arranged at the front end of the sheet taking bracket 31, a plurality of suction cups 33 arranged below the suction cup bracket 32, and a rotating mechanism 34 arranged above the suction cup bracket 32. A slide rail is arranged on the lifting bracket 2, and the sheet taking bracket 31 is slidably connected with the slide rail of the lifting bracket 2. The sliding connection method can be that a motor is arranged on the lifting bracket 2, a gear is arranged at one end of the output shaft of the motor, a rack is arranged on the sheet taking bracket 31, the gear and the rack are meshed, the motor rotates, drives the gear to rotate, drives the rack to move back and forth, and further drives the sheet taking bracket 31 to slide back and forth on the lifting bracket 2. The sliding connection method can also be that a cylinder or a hydraulic cylinder drives the telescopic rod to extend and retract, and further drives the sheet taking bracket 31 to slide back and forth on the lifting bracket 2.

[0039] As Figure 5 shown, when viewed from the glass conveying direction, the lifting bracket 2 is trapezoidally arranged, the upper end of the lifting bracket 2 is shorter, the lower end is longer, and the lower part of the lifting bracket 2 has a concave space for the sheet taking assembly 3 to slide. This lifting bracket 2 has a more stable structure and stronger bearing capacity.

[0040] In this embodiment, there are multiple slide rails on the lifting bracket 2. The multiple slide rails are divided into several first slide rails 21 and several second slide rails 22. The first slide rails 21 are arranged at the top of the concave space of the lifting bracket 2, and the second slide rails 22 are arranged at the sides of the concave space of the lifting bracket 2. The length directions of the first slide rails 21 and the second slide rails 22 are parallel, and the height directions are perpendicular to each other. Sliders are provided at corresponding positions of the glass picking bracket 31, and the sliders are respectively connected to the first slide rails 21 and the second slide rails 22, so that the force exerted by the glass picking assembly 3 on the lifting bracket 2 is more evenly distributed, making the structure of the glass picking device 104 more stable, with stronger load-bearing capacity, and capable of grasping a larger reverse-bent glass 5. Preferably, there are 2 first slide rails 21 and also 2 second slide rails 22. It can be understood that the number of the first slide rails 21 and the second slide rails 22 can be arbitrary.

[0041] As Figure 3 , Figure 4 shown, the upper end of the suction cup holder 32 passes through the glass picking bracket 31. The suction cup holder 32 can only rotate relative to the glass picking bracket 31, and there is no space for front-back movement or left-right movement in the horizontal plane, making the suction cup holder 32 relatively stable during movement and avoiding shaking of the suction cup holder 32 during the glass picking process. The upper end of the suction cup holder 32 is connected to the rotation mechanism 34, and the rotation mechanism 34 can drive the suction cup holder 32 to rotate. The rotation mechanism 34 includes a driving member 341 and a rotation connecting member 342. The driving member 341 can be a cylinder, a hydraulic cylinder, etc. As Figure 4 shown, the two ends of the rotation connecting member 342 are respectively connected to the upper end of the suction cup holder 32 and the driving member 341. In the initial position, the two ends of the rotation connecting member 342 are offset in the direction perpendicular to the glass conveying direction in the horizontal plane. The driving member 341 drives the rotation connecting member 342 to rotate, and then drives the suction cup holder 32 to rotate. After the glass is reverse-bent and formed, it cannot be directly conveyed because the two sides of the reverse-bent glass 5 are parallel to the roller path of the conveying mechanism 4, and the two sides of the reverse-bent glass 5 will be inserted into the gap between the roller paths. By rotating the glass by a certain angle through the rotation mechanism 34, the two sides of the reverse-bent glass 5 are not parallel to the roller path of the conveying mechanism 4, so that the conveying mechanism 4 can directly convey the reverse-bent glass 5.

[0042] Preferably, the rotation angle is 90°. A 90° rotation angle is easy to control, and the reverse-bent glass 5 is not prone to deviation during conveying after rotation, and is easier to operate when conveyed to the next working station or stacked for the next piece. Of course, as long as the glass is rotated by a certain angle so that the two sides of the reverse-bent glass 5 do not fall into the roller gap, the rotation angle can be 30°, 45°, 120°, 135°, etc.

[0043] In other embodiments, the rotation mechanism 34 can be a rotating motor, and the rotating motor is connected to the upper end of the suction cup holder 32 to drive the suction cup holder 32 to rotate.

[0044] The suction cup 33 is connected to the suction cup holder 32 through a suction cup rod. The upper end of the suction cup rod is fixedly connected to the suction cup holder 32. The lower end of the suction cup rod is spherical, and the upper end of the suction cup 33 is sleeved on the lower end of the suction cup rod and can rotate freely around the spherical part at the lower end of the suction cup rod. The suction cup 33 is connected to the vacuum air path. The suction cup 33 can rotate relatively, so that the suction cup 33 can better fit the curved surface of the reverse-bent glass 5, making the adsorption of the reverse-bent glass 5 more stable.

[0045] The sheet taking device 104 further includes a lifting assembly. The lifting assembly includes a lifting motor and multiple lifting chains. The lifting motor is arranged at the upper end of the frame 1. One end of the multiple lifting chains is connected to multiple lifting points of the lifting bracket 2. The multiple lifting points are dispersedly arranged on the four peripheral edges of the lifting bracket 2. For example, four lifting points can be arranged at the four corners of the lifting bracket 2, or six lifting points can be arranged on two opposite sides of the lifting bracket. The dispersed arrangement of the lifting points makes the lifting process more stable and the force on the lifting bracket 2 more balanced. The entire lifting bracket 2 can be driven to lift by one lifting motor.

[0046] The sheet taking device 104 further includes a counterweight 6. The counterweight 6 is arranged on one side or both sides of the frame 1 in the conveying direction. The other ends of the multiple lifting chains are connected to the counterweight 6. The counterweight 6 makes the lifting process more stable and can also make the required power of the lifting motor smaller.

[0047] In other embodiments, the lifting assembly can adopt a cylinder or a hydraulic cylinder. In this case, multiple cylinders or hydraulic cylinders need to be arranged to ensure the stability of lifting.

[0048] Sheet taking process:

[0049] The sheet taking assembly 3 slides forward along the glass conveying direction until the suction cup 33 moves above the reverse-bent glass 5. The lifting bracket 2 descends, driving the suction cup 33 to fit the reverse-bent glass 5. The vacuum air path works to extract the air inside the suction cup 33, so that the suction cup 33 sucks the reverse-bent glass 5. Then the lifting bracket 2 rises, driving the reverse-bent glass 5 to rise. Subsequently, the rotating mechanism 34 acts, driving the reverse-bent glass 5 to rotate 90°. At this time, the sheet taking assembly 3 slides backward until the reverse-bent glass 5 moves above the conveying mechanism 4, or the reverse-bent glass 5 first moves above the conveying mechanism 4 and then rotates 90°. Finally, the lifting bracket 2 descends, the vacuum air path stops working, and the reverse-bent glass 5 is placed on the conveying mechanism 4. The conveying mechanism 4 conveys the reverse-bent glass 5 to the next working station. The entire sheet taking process separately controls the lifting action and the forward and backward sliding actions, making the overall sheet taking action more stable, not causing the shaking of the reverse-bent glass 5, and avoiding the collision of the reverse-bent glass 5 during the sheet taking process. Embodiment

[0050] The difference from Embodiment 1 is that in this embodiment, the sheet taking assembly 3 is divided into two sections, the front and the rear. The sheet taking assembly 3 includes a front sheet taking bracket and a rear sheet taking bracket. The rear sheet taking bracket is slidably connected to the slide rail of the lifting bracket 2, and the rear sheet taking bracket can slide back and forth along the slide rail of the lifting bracket 2. A slide rail is also provided on the rear sheet taking bracket, and the front sheet taking bracket is slidably connected to the slide rail of the rear sheet taking bracket, and the front sheet taking bracket can slide back and forth along the slide rail of the rear sheet taking bracket. The sliding connection method can adopt the method in Embodiment 1 and will not be elaborated here. In this embodiment, the suction cup holder 32, the suction cups 33, and the rotating mechanism 34 are all arranged on the front sheet taking bracket. Dividing the sheet taking bracket 31 into two brackets, the front and the rear, can make the front sheet taking bracket retract below the rear sheet taking bracket, that is, reduce the overall length of the sheet taking bracket, and further enable the total length of the sheet taking device 104 to be set shorter, further reducing the floor area. The sheet taking device 104 in this embodiment is suitable for taking sheets of the smaller reverse-bent glass 5. Embodiment
