[0002] In a glass processing production line, when the operation cycle of an upstream device is obviously faster than that of a downstream device, the phenomenon of glass sheet blockage will occur.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] The following will be described according to the accompanying Figure 1 to the accompanying Figure 9 The glass buffering device provided by the present application is introduced.

[0046] As Figure 1 , Figure 2 shown, the glass buffering device is mainly arranged at the conveying device, and can buffer the glass sheet flowing through the conveying device. In the present embodiment, the conveying device has a plurality of conveying rollers 100, which are arranged in parallel and at intervals. For the convenience of description, the arrangement direction of the conveying rollers 100 is defined as a preset first direction, and the axial direction of the conveying rollers 100 is defined as a preset second direction, and the preset first direction and the preset second direction are arranged perpendicularly.

[0047] The glass buffering device includes at least two lifting mechanisms 1, each of which can be supported from bottom to top at a position of the bottom surface of the glass sheet, and when the plurality of lifting mechanisms 1 collectively support the glass sheet, the glass sheet can be lifted and separated from the conveying rollers 100, achieving the effect of temporary storage.

[0048] Figure 1 is a perspective view of the glass buffering device and the conveying device in the zero storage state, Figure 2 is a perspective view of the glass buffering device and the conveying device in the full storage state (the glass sheet is not shown in the figure), Figure 3 is a front view of the glass buffering device and the conveying device in the zero storage state (along the preset first direction), Figure 4 is a front view of the glass buffering device and the conveying device in the full storage state. AsFigure 1 、 Figure 3 As shown in FIG. 1, a plurality of lifting mechanisms 1 are arranged along a preset first direction, each of which includes a first sprocket 111, a second sprocket 112, a lifting chain 114, a lifting piece 12, and a third sprocket 113. The first sprocket 111 is rotatably arranged above the conveying roller 100, the second sprocket 112 is rotatably arranged below the conveying roller 100, and the lifting chain 114 is connected to the first sprocket 111 and the second sprocket 112.

[0049] Continuing to refer to FIG. 1, Figure 2 to Figure 4 As shown in FIG. 1, the lifting chain 114 extends in the vertical direction and is arranged through the gap between two adjacent conveying rollers 100. Meanwhile, along a preset second direction, the lifting chain 114 is located at the end of the conveying roller 100 to avoid blocking the normal conveying of the glass sheet. Along the extension direction of the lifting chain 114, a plurality of lifting pieces 12 are connected to the lifting chain 114, and the lifting pieces 12 can abut against the lower surface of the supported glass sheet. When in the zero storage state, the lifting pieces 12 are hidden below the conveying roller 100 by rotating the lifting chain 114, so as to avoid the negative impact of the lifting pieces 12 on the normal conveying. When the blocking phenomenon occurs and needs to be stored, as shown in FIG. 2, at least part of the lifting pieces 12 are raised with the rotation of the lifting chain 114, so that the glass sheet is lifted away from the conveying roller 100 for temporary storage. When the blocking phenomenon is solved, the lifting pieces 12 can be moved to the conveying roller 100 below by rotating the lifting chain 114, so as to place the glass sheet on the conveying roller 100 and release the buffered glass sheet. Figure 4

[0050] As shown in FIG. 1, along the extension direction of the lifting chain 114, an accommodation space is formed between two adjacent lifting pieces 12, and each accommodation space can accommodate one glass sheet. That is, the factors that limit the capacity of the glass buffering device mainly include the internal size (mainly the height direction) of the glass buffering device, the size (height direction) of the accommodation space, and the number of lifting pieces 12. Figure 4

[0051] Therefore, as shown in FIG. 3, Figure 5 、 Figure 6 ​​As shown in the embodiment, a third sprocket 113 is further arranged below the conveying roller 100. The third sprocket 113 is rotatably arranged and abuts the lifting chain 114, so that the part of the lifting chain 114 below the conveying roller 100 has at least one bending. By bending the lifting chain 114, the length of the part of the lifting chain 114 below the conveying roller 100 is increased, so that the number of lifting members 12 connected by the part is increased. In this way, the capacity of the glass buffer device can be increased by increasing the number of lifting members 12 without changing the internal size of the glass buffer device and the size of the accommodating space, and the lifting members 12 can still be located below the conveying roller 100 in the zero storage state, so that the increase in the number of lifting members 12 does not negatively affect the conveying and buffering of the glass sheets.

[0052] As shown in the embodiment, Figure 4 , Figure 5 each lifting mechanism 1 includes two lifting assemblies 11 arranged along the preset second direction. Each lifting assembly 11 includes a lifting chain 114, a first sprocket 111, two second sprockets 112, and at least one third sprocket 113, and the lifting chain 114 in each lifting assembly 11 is connected to the first sprocket 111, the second sprockets 112, and the third sprocket 113 in the lifting assembly 11. In addition, the third sprocket 113 is located between the two second sprockets 112 along the extension direction of the lifting chain 114. The two second sprockets 112 are connected to the lifting chain 114 and can abut the lifting chain 114 along the preset first direction, so as to ensure that the lifting chain 114 passes through the gap between the conveying rollers 100 in the vertical direction.

[0053] As shown in the embodiment, Figure 5 , Figure 6 the part of the lifting chain 114 between the first sprocket 111 and the second sprockets 112 has a perpendicularity error of no more than 0.4 mm with respect to the preset first direction. The smaller the perpendicularity error, the more likely the lifting member 12 can maintain a relative fixation with the glass sheet during the lifting of the glass sheet by the lifting member 12, so as to avoid scratching the bottom surface of the glass sheet by the lifting member 12.

[0054] As shown in the embodiment, Figure 6 to Figure 8 the application discloses various arrangements of the third sprocket 113 to meet the restrictions of different installation conditions such as different conveying devices. As shown in the embodiment, Figure 6As shown, along the preset first direction, one third sprocket 113 is arranged between two second sprockets 112. Two second sprockets 112 abut against the lifting chain 114 from the inner side of the lifting chain 114, and the third sprocket 113 abuts against the lifting chain 114 from the outer side of the lifting chain 114, so that the part of the lifting chain 114 under the conveying roller 100 is bent into a W shape, thereby achieving the lengthening of the lifting chain 114 and the increase of the number of lifting members 12. The W-shaped arrangement is conducive to the arrangement of the glass buffer device in the case of limited space along the preset first direction.

[0055] As shown in some embodiments, Figure 7 As shown, along the preset first direction, one third sprocket 113 is arranged between two second sprockets 112. Two second sprockets 112 abut against the lifting chain 114 from the inner side of the lifting chain 114, and the third sprocket 113 abuts against the lifting chain 114 from the outer side of the lifting chain 114, so that the part of the lifting chain 114 under the conveying roller 100 is bent into a W shape, thereby achieving the lengthening of the lifting chain 114 and the increase of the number of lifting members 12. The W-shaped arrangement is conducive to the arrangement of the glass buffer device in the case of limited space along the preset first direction.

[0056] As shown in some other embodiments, Figure 8 As shown, along the preset first direction, one third sprocket 113 is arranged between two second sprockets 112. Two second sprockets 112 abut against the lifting chain 114 from the inner side of the lifting chain 114, and the third sprocket 113 abuts against the lifting chain 114 from the outer side of the lifting chain 114, so that the part of the lifting chain 114 under the conveying roller 100 is bent into a W shape, thereby achieving the lengthening of the lifting chain 114 and the increase of the number of lifting members 12. The W-shaped arrangement is conducive to the arrangement of the glass buffer device in the case of limited space along the preset first direction.

[0057] More specifically, in the present embodiment, the lifting member 12 comprises a hollow rod, and a connecting pin is arranged on the lifting chain 114, and the two ends of the hollow rod are connected to the connecting pin in a plug-in manner, so that the hollow rod is connected between two lifting chains 114 and can move following the rotation of the lifting chain 114. At the same time, compared with solid rod members, the hollow rod has a smaller weight, which can reduce the load of the lifting chain 114 and the driving mechanism 3 for driving the rotation of the lifting chain 114. Preferably, the hollow rod is rotatably arranged through the connecting pin, thereby further avoiding the hollow rod from scratching the bottom surface of the glass sheet and facilitating the reduction of error accumulation.

[0058] It should be noted that the driving mechanism 3 driving the lifting chain 114 can be a motor or other structure, or can be connected to the driving device driving the transmission device through a controllable transmission mechanism, thereby providing power for the action of the glass buffer device, and thus the specific structure of the driving mechanism 3 is not limited.

[0059] Optionally, in the embodiment, as shown in Figure 9 the glass buffer device further comprises a support 2 and a driving mechanism 3, the support 2 and the transmission device are fixedly arranged, the lifting mechanism 1 and the driving mechanism 3 are fixedly installed on the support 2, and the driving mechanism 3 is drivingly connected to the lifting chain 114 to provide power for the rotation of the lifting chain 114.

[0060] Specifically, the driving mechanism 3 comprises a driving assembly 31 and a transmission assembly 32, and the driving assembly 31 and the transmission assembly 32 are both installed on the support 2 and arranged above the conveying roller 100. The driving assembly 31, the transmission assembly 32 and the first sprocket 111 are drivingly connected, the driving assembly 31 drives the first sprocket 111 to rotate through the transmission assembly 32, thereby causing the lifting chain 114 to rotate.

[0061] More specifically, as shown in Figure 9 the transmission assembly 32 comprises a lifting shaft 321, a transmission chain 322 and a transmission wheel 323. At least two lifting shafts 321 are arranged in a preset first direction, and the axis direction of the lifting shaft 321 is parallel to the preset second direction. The two ends of the lifting shaft 321 are respectively connected with the first sprocket 111 in one of the lifting assemblies 11, and the lifting shaft 321 is sleeved with the transmission wheel 323, and part of the transmission chain 322 extends along the preset second direction to drivingly connect the at least two lifting shafts 321 through the transmission wheel 323. The driving mechanism 3 is directly drivingly connected with one of the lifting shafts 321, and is drivingly connected between the plurality of lifting shafts 321 through the transmission chain 322 and the transmission wheel 323, thereby realizing the synchronous action of the plurality of lifting assemblies 11.

[0062] Further specifically, in the embodiment, the driving assembly 31 comprises a hollow shaft speed reducer, and the transmission assembly 32 comprises a tensioning sleeve 325 and a tensioning piece 324, the tensioning sleeve 325 is connected between the lifting shaft 321 and the first sprocket 111, and the tensioning piece 324 abuts against the transmission chain 322 to tension the transmission chain 322. The tensioning piece 324 can compress the transmission chain 322 to avoid the accumulation of transmission errors caused by loosening and relaxation of the transmission chain 322, so that all the lifting chains 114 can rotate at the same time, avoiding the time difference when the glass sheet is lifted, causing the glass sheet to tilt around the preset second direction, and ensuring the position accuracy in the lifting direction.

[0063] The expansion sleeve 325 can stably connect the first sprocket 111 and the lifting shaft 321, for example, by generating a clamping force through bolts, so that the first sprocket 111 and the lifting shaft 321 are connected without keys, ensuring that the angle of each tooth of all the first sprockets 111 is consistent after debugging, thereby ensuring that the spacing between each glass sheet is consistent. In this way, during the storage process, only the lifting chain 114 needs to be moved according to the preset pitch (i.e., the distance between two adjacent lifting members 12), thereby ensuring the position accuracy in the preset first direction and in the vertical direction during storage.

[0064] It should be noted that the driving assembly 31 is arranged at the top of the glass storage device, which is beneficial to reduce the length of the transmission path between the driving assembly 31 and the first sprocket 111, and reduce the transmission error. Therefore, preferably, the glass storage device further comprises a ladder 4, which is detachably connected to the support 2 and adjustably connected to at least one side of the support 2 in the preset first direction. By moving the ladder 4 in the preset first direction, it is convenient for maintenance personnel to detect and maintain the driving mechanism 3 at any position, thereby improving the maintenance efficiency.

[0065] Exemplarily, in the embodiment, the support 2 is provided with an embedded groove 21 in the preset first direction, and the top of the ladder 4 is provided with a hook which can be embedded into the embedded groove 21 to fix the ladder 4. When it is necessary to move the ladder 4, the hook only needs to be slid along the extension direction of the embedded groove 21, so that the fixing position of the ladder 4 in the preset first direction can be changed. Preferably, the support 2 is provided with an embedded groove 21 on both sides in the preset first direction, so that the ladder 4 can be fixed at any position on the two sides of the glass storage device.

[0066] In one embodiment of the present application, a production line modification method is also disclosed, which is used to arrange the above-mentioned glass storage device on a glass production line. Specifically, the method comprises:

[0067] At least four first sprockets 111 are arranged above the conveying rollers 100, at least eight second sprockets 112 are arranged below the conveying rollers 100, one lifting chain 114 is arranged and connected between every two second sprockets 112 and a corresponding first sprocket 111, a lifting member 12 is arranged and connected on the lifting chain 114, so that the lifting chain 114 and the lifting member 12 can move through the gap between the conveying rollers 100, and a third sprocket 113 is arranged below the conveying rollers 100, the third sprocket 113 is connected and abuts with the lifting chain 114, so that the lifting chain 114 is bent at the abutting position.

[0068] It should be noted that, since the number of lifting chains 114 that can be set in different production lines is different, the number of lifting chains 114, the number of first sprockets 111, the number of second sprockets 112, the number of third sprockets 113 and the number of lifting members 12 in the present application are not limited, as long as the above-mentioned glass buffer device can be obtained by the method. Moreover, the order of the language description in the method does not limit the sequence of the actual installation steps, for example, the first sprocket 111 can be set first, or the second sprocket 112 can be set first, or the first sprocket 111 and the second sprocket 112 can be set at the same time, or the first sprocket 111, the second sprocket 112, the lifting chain 114 and the lifting member 12 can be set first, and then the third sprocket 113 is set and connected with the lifting chain 114, and the like, which all belong to the scope to be protected by the present application.

[0069] Exemplarily, in specific implementation, the support 2 can be set first, and the installation positions of the first sprocket 111 and the second sprocket 112 can be determined and checked in a marked manner on the support 2. Then, the first sprocket 111 and the second sprocket 112 are installed on the support 2 (or the rack of the conveying device) through the shaft mounting seat and the sprocket connecting shaft. Preferably, during installation, the midpoint position of the line connecting the two second sprockets 112 and the center position of the first sprocket 111 are coincidentally arranged in the vertical direction, so that the first sprocket 111 can be centrally arranged relative to the two second sprockets 112 in the preset first direction. Alternatively, in the present embodiment, as long as the deviation is not more than 0.25 mm, it can be considered as coincidentally arranged.

[0070] Then, the third sprocket 113, the lifting chain 114 and the lifting member 12 can be continuously installed, and the lifting chain 114 is tensioned, and finally the perpendicularity error between the lifting chain 114 and the conveying roller 100 is measured, which is ensured to be not more than 0.4 mm. Alternatively, the relative lifting value of each lifting chain 114 and the lifting member 12 when carrying the glass sheet can also be measured and compared, as long as the error of the relative lifting value is not more than 0.2 mm.

[0071] Of course, in some embodiments, there are cases where the first sprocket 111, the second sprocket 112, the lifting member 12 and the lifting chain 114 have been set, at this time, only the original second sprocket 112 is changed into a second sprocket 112 with a smaller diameter to adapt to the addition of the third sprocket 113, and the original lifting chain 114 is changed into a lifting chain 114 with a longer length and connected with more lifting members 12.

[0072] The third sprocket 113 is arranged below the conveying roller 100 and abuts against the lifting chain 114, so that the part of the lifting chain 114 below the conveying roller 100 has at least one bending. By bending the lifting chain 114, the length of the part of the lifting chain 114 below the conveying roller 100 is increased, so that the number of lifting members 12 connected by the part is increased. In this way, the capacity of the glass buffer device can be increased by increasing the number of lifting members 12 without changing the internal size of the glass buffer device and the size of the accommodating space, and the lifting members 12 can still be located below the conveying roller 100 in the zero storage state, so that the increase of the number of lifting members 12 does not have a negative impact on the conveying and buffering of the glass sheets.

In the present specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0074] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application.
