Description

Technical Field

[0001] The utility model belongs to the technical field of glass conveying, and particularly relates to a curved glass conveying unit and a conveying device. Background Art

[0002] Curved glass needs to be conveyed by a conveying device. For example, the conveying device for curved tempered glass with the patent application number CN201921303611.8 uses arc plates, a flexible shaft roller path and a transition shaft to realize the conveying of glass. Multiple arc plates and corresponding multiple flexible shaft roller paths need to be set to realize the conveying of glass. The structure is complex, the cost is high, and the heights of all arc plates and flexible shaft roller paths need to be adjusted to keep the glass on a conveying plane. There is no positioning of the glass during the conveying process, and the glass is prone to sway left and right during the conveying process, resulting in unstable conveying. Summary of the Invention

[0003] The purpose of the utility model is to provide a curved glass conveying unit and a conveying device with stable conveying and simple structure.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A curved glass conveying unit includes a conveying shaft and a plurality of edge conveying wheels. Conveying rollers are arranged on the conveying shaft. A plurality of the edge conveying wheels are all arranged above the conveying rollers and on both sides of the conveying rollers; the axes of the edge conveying wheels are inclined.

[0006] The beneficial effects are as follows: The conveying rollers and the edge conveying wheels jointly form a conveying plane for the curved glass, simplifying the structure of the conveying device, and the height of the conveying shaft is easy to adjust, so that the conveying plane of the curved glass remains consistent in the glass conveying direction. The conveying wheels on both sides increase the supporting points on both sides of the curved glass, effectively supporting both sides of the curved glass, so that the shape of the curved glass remains stable during the conveying process.

[0007] Further, the surface of the conveying roller has a concave arc.

[0008] The beneficial effects are as follows: The concave arc on the surface of the conveying roller increases the contact position and friction force with the bottom of the curved glass, making the curved glass more stable during the conveying process.

[0009] A curved glass conveying device for conveying curved glass includes a plurality of conveying units, and the conveying units adopt any one of the above-mentioned conveying units; a plurality of the conveying units are arranged in parallel at intervals along the glass conveying direction, and the center lines of the plurality of conveying units in the horizontal plane are all on a straight line.

[0010] The beneficial effects are as follows: The structure is simple and the conveying is stable.

[0011] Further, it further includes two groups of top limiting wheels; the two groups of top limiting wheels are respectively located on both sides perpendicular to the glass conveying direction and above the edge conveying wheels; each group of top limiting wheels includes a plurality of top limiting wheels, and the plurality of top limiting wheels are arranged at intervals along the glass conveying direction; the axis of the top limiting wheel is horizontally arranged.

[0012] The beneficial effect is that the top limiting wheels limit the top of both sides of the curved glass, prevent the curved glass from shaking left and right, and can straighten the top surfaces of both sides of the curved glass.

[0013] Further, it further includes two groups of profiling side limiting wheels; the two groups of profiling side limiting wheels are respectively located on both sides perpendicular to the glass conveying direction and above the edge conveying wheels; each group of profiling side limiting wheels includes a plurality of profiling side limiting wheels, and the plurality of profiling side limiting wheels are arranged at intervals along the glass conveying direction; the axis of the profiling side limiting wheel is vertically arranged.

[0014] The beneficial effect is that the profiling side limiting wheels further prevent the curved glass from shaking left and right, and form a certain clamping effect on both sides of the curved glass, which can effectively avoid the warping of the edges of the curved glass.

[0015] Further, the surface of the profiling side limiting wheel has an arc shape adapted to the shape of the edge of the curved glass.

[0016] The beneficial effect is that it can help the shaping of both sides of the curved glass.

[0017] Further, the plurality of edge conveying wheels on each side perpendicular to the glass conveying direction are respectively arranged on a first edge bracket; the first edge bracket can be lifted and adjusted left and right.

[0018] The beneficial effect is that the position of the conveying wheels can be adjusted by adjusting the first edge bracket, so as to adapt to the conveying of curved glass with different sizes and different curvatures.

[0019] Further, the two groups of top limiting wheels and the two groups of profiling side limiting wheels are arranged at the entrance of the conveying device.

[0020] The beneficial effect is that the glass can be positioned at the initial stage when the glass enters the conveying device. As the glass is conveyed and cooled and tempered, the shape of the glass is gradually fixed. Only the conveying rollers and conveying wheels are needed in the middle and later stages to ensure the stable conveying of the glass. It is beneficial to simplify the structure and cost of the conveying device.

[0021] Further, each group of top limiting wheels and each group of profiling side limiting wheels are arranged on a second edge bracket; the second edge bracket can be lifted and adjusted left and right.

[0022] Its beneficial effects are that by adjusting the second side bracket, the positions of multiple profiling side limit wheels and multiple top limit wheels can be adjusted to adapt to the conveyance of curved glass with different sizes and curvatures.

[0023] The beneficial effects of the present utility model are as follows: The curved glass is conveyed by the combined action of the conveying rollers and the side conveying wheels, which simplifies the structure of the conveying unit, and each conveying unit is consistent in the glass conveying direction, making the conveyance of the curved glass more stable. The top limit wheels and the profiling side limit wheels are used to limit the curved glass, making the conveyance further stable and capable of calibrating the shape of the curved glass.

[0030] The following will further elaborate on the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for any limitation to the utility model.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

Example 1

[0032] As shown in the Figure 1 accompanying drawings, a curved glass conveying unit includes a conveying shaft 1 and a plurality of edge conveying wheels 2. A conveying roller 101 is provided in the middle of the conveying shaft. A plurality of edge conveying wheels 2 are all arranged above the conveying shaft and on both sides of the conveying roller 101. The axes of the edge conveying wheels 2 are inclined. The included angle between the axis of the edge conveying wheel and the axis of the conveying roller 101 is α, and α is an acute angle. The conveying roller 101 and the edge conveying wheels 2 cooperate to convey the curved glass 7.

[0033] In this embodiment, each conveying unit includes a conveying shaft 1 and two edge conveying wheels 2, and a conveying roller 101 is provided in the middle of the conveying shaft 1. In other embodiments, each conveying unit may include a conveying shaft 1 and four edge conveying wheels 2, and a plurality of conveying rollers 101 are provided in the middle of the conveying shaft 1. The four edge conveying wheels 2 are respectively arranged above the conveying shaft 1 and on both sides of the conveying rollers 101, forming more support points on both sides of the curved glass 7.

[0034] Using the conveying roller 101 and the edge conveying wheels 2 to replace the arc plate, the soft shaft roller path, and the transition shaft in the patent of CN201921303611.8 simplifies the structure of the conveying device, and it is easy to ensure the consistency of the height of the conveying shaft in the glass conveying direction during installation, so that the conveying surface of the curved glass 7 remains horizontal. While the comparative document needs to ensure the accuracy of each arc plate and the height of each soft shaft roller path to ensure that the conveying surface of the curved glass 7 remains horizontal, and the adjustment is complex. The edge conveying wheels 2 increase the support points on both sides of the curved glass 7, effectively supporting both sides of the curved glass 7, so that the shape of the curved glass 7 remains stable during the conveying process.

[0035] In this embodiment, the surface of the conveying roller 101 has a concave arc. Specifically, the surface of the conveying roller 101 can be an integral concave arc, or two oblique lines in an inverted "V" shape, and the intersection of the two oblique lines is transitioned by an arc. The concave arc on the surface of the conveying roller 101 increases the contact area and friction between the conveying roller 101 and the curved glass 7, making the curved glass 7 more stable during the conveying process. In other embodiments, the surface of the conveying roller 101 is a horizontal straight line, which can also play the role of conveying the curved glass 7.

[0036] The edge conveyor wheel 2 can be a follower or a driver. In this embodiment, the edge conveyor wheel 2 is a follower and has no power of its own. Instead, it rolls freely as the curved glass 7 is conveyed. In other embodiments, a transmission mechanism can be provided for the edge conveyor wheel 2 to actively convey the glass. The transmission mechanism can be a conventional transmission method such as shaft transmission, chain transmission, or belt transmission. When the edge conveyor wheel is a driving wheel, it is only necessary to ensure that its conveying speed is consistent with the conveying shaft, and the curved glass 7 can be conveyed more smoothly. Embodiment 2

[0037] As shown in the attached Figure 2 to the attached Figure 4 As shown, a curved glass conveying device for conveying curved glass includes a plurality of conveying units, and the conveying units adopt the conveying units described in Embodiment 1; the plurality of conveying units are arranged in parallel at intervals along the glass conveying direction, and the center lines of the plurality of conveying units in the horizontal plane are all on a straight line.

[0038] The conveying device is further provided with a top limiting wheel 3 and a profiling side limiting wheel 4.

[0039] The conveying device includes two groups of top limiting wheels 3. Each group of top limiting wheels 3 includes a plurality of top limiting wheels 3, and the plurality of top limiting wheels 3 are arranged at intervals along the glass conveying direction. The two groups of top limiting wheels 3 are respectively located on both sides perpendicular to the glass conveying direction and above the edge conveyor wheel 2. Specifically, the top limiting wheels 3 are located above the two side edges of the curved glass 7 perpendicular to the glass conveying direction. The axes of the top limiting wheels 3 are horizontally arranged. The bottom surface of the top limiting wheels 3 is in contact with the top surfaces of the two sides of the curved glass 7 for limiting the top of the two sides of the curved glass 7 to prevent the curved glass 7 from shaking left and right, and the bottom of the top limiting wheels 3 is straight to straighten the edges of the curved glass 7.

[0040] The conveying device further includes two groups of profiling side limiting wheels 4. Each group of profiling side limiting wheels 4 includes a plurality of profiling side limiting wheels 4, and the plurality of profiling side limiting wheels 4 are arranged at intervals along the glass conveying direction. The two groups of profiling side limiting wheels 4 are respectively located on both sides perpendicular to the glass conveying direction and above the edge conveyor wheel 2. Specifically, the profiling side limiting wheels 4 are located outside the two side edges of the curved glass 7 perpendicular to the glass conveying direction. The axes of the profiling side limiting wheels 4 are vertically arranged. The profiling side limiting wheels 4 further prevent the curved glass 7 from shaking left and right and form a certain clamping effect on the edges of the curved glass 7, which can effectively avoid warping of the edges of the curved glass 7.

[0041] Preferably, the surface of the profiling side limiting wheel 4 has an arc shape adapted to the edge shape of the curved glass 7, so that it is basically consistent with the edge line of the curved glass 7, which can help shape the two side edges of the curved glass 7.

[0042] Preferably, the two sets of profiling side limit wheels 4 and the two sets of top limit wheels 3 are only provided at the entrance of the conveying device. That is, on the basis of the first several conveying units at the front end in the glass conveying direction, two sets of profiling side limit wheels 4 and two sets of top limit wheels 3 are provided, and the conveying units in the middle and rear end in the glass conveying direction are still the conveying units described in Embodiment 1. The glass is limited at the initial stage when the curved glass 7 enters the conveying device, and the curved shape of the curved glass 7 is calibrated, especially the shape of both sides of the curved glass 7. As the curved glass 7 is conveyed and cooled, the shape of the curved glass 7 is gradually fixed, and only the conveying rollers 101 and the edge conveying wheels 2 are needed in the middle and rear sections to ensure the stable conveying of the curved glass 7. This is beneficial to simplifying the structure of the conveying device and reducing the manufacturing cost.

[0043] Of course, the two sets of profiling side limit wheels 4 and the two sets of top limit wheels 3 can be provided in the entire conveying device, that is, all the conveying units in the conveying device are provided with profiling side limit wheels 4 and top limit wheels 3 on the basis of the conveying units described in Embodiment 1.

[0044] A plurality of edge conveying wheels 2 on each side perpendicular to the glass conveying direction are respectively arranged on the first edge bracket 5. The first edge bracket 5 can be lifted and adjusted left and right. The adjustment method of the first edge bracket 5 can be manually adjusted and then fixed on the frame of the conveying device before use, or can be automatically adjusted by a driving mechanism such as a cylinder, a hydraulic cylinder, a motor, etc. By adjusting the first edge bracket 5, the position of the edge conveying wheels 2 can be adjusted, so as to adapt to the conveying of curved glass 7 with different sizes and different curvatures.

[0045] A set of profiling limit wheels 4 and a set of top limit wheels 3 on the same side perpendicular to the glass conveying direction are arranged on the second edge bracket 6, and the second edge bracket 6 can be lifted and adjusted left and right. In this embodiment, the second edge bracket 6 is movably connected to the first edge bracket 5. For example, a chute is arranged on the first adjustment bracket 5, and the second edge bracket 6 is provided with a height adjustment bolt and a slide bar inserted into the chute. After the first edge bracket 5 is adjusted, only the height of the second edge bracket 6 needs to be finely adjusted by the height adjustment bolt, and the left and right distance of the second edge bracket 6 is finely adjusted by the movement of the slide bar in the chute. By adjusting the second edge bracket 6, the positions of the plurality of profiling side limit wheels 4 and the plurality of top limit wheels 3 can be adjusted to adapt to the conveying of curved glass 7 with different sizes and different curvatures.

[0046] In other embodiments, the second edge bracket 6 can be independently adjusted, and the adjustment method can be manual adjustment or automatic adjustment using a conventional driving mechanism.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced by referring to the above embodiments. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention is within the scope of protection of the claims pending for approval.
