Description

Technical Field

[0001] An upper and lower sheet transfer device for a glass plate belongs to the technical field of glass production. Background Art

[0002] A glass loading table is a device that transports glass (especially glass plates) from a glass rack to subsequent processes. For example, the technical solutions disclosed in the Chinese utility model patent with the application number 201720050063.7, the application date of January 16, 2017, and the patent name of "A Glass Loading Table for Automatic Scoring and Breaking", and the Chinese utility model patent with the application number 201921640561.2, the application date of September 29, 2019, and the patent name of "A Device for Preventing Sucker from Lifting Sheets on a Glass Loading Table".

[0003] In the prior art, a temporary transfer rack is generally provided at the output end of the glass loading table. After the glass is output from the glass loading table, it is first placed on the temporary transfer rack and then sent to subsequent processes in sequence. Since the distance between the subsequent process and the temporary transfer rack is sometimes large, the secondary transfer is still difficult. The Chinese utility model patent with the application number 201520151180.3, the application date of March 17, 2015, and the patent name of "A Flip Arm Structure of a Glass Loading Table" discloses a technical solution. In this technical solution, the bottom of the frame of the glass loading table is provided with pulleys, so after taking the glass, it can be directly sent to the subsequent process. Although this technical solution omits the process of secondary transfer, it still requires manual transportation, which not only has a large labor intensity but also has certain safety hazards. Therefore, designing a technical solution to avoid manual long-distance secondary transfer after taking the glass has become an urgent problem in this field. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide an upper and lower sheet transfer device for a glass plate. By setting a moving bottom plate with pulleys, connecting the front and rear processes through the sliding bottom plate, respectively setting flipping mechanisms at the feeding end and the discharging end of the moving bottom plate, and connecting the flipping mechanisms at both ends through an auxiliary transfer mechanism, after taking the glass, the transfer of the glass plate is realized by using the auxiliary transfer mechanism, omitting the transfer rack and reducing the labor intensity at the same time.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: The upper and lower sheet transfer device for this glass plate includes a fixed bottom plate, on which a flipping mechanism is installed, and on the surface of the flipping mechanism, there are suction cups for adsorbing the glass plate. It is characterized in that: A moving bottom plate is slidably arranged above the fixed bottom plate. The two ends of the moving bottom plate are respectively a feeding end and a discharging end. Flipping mechanisms are respectively arranged at the feeding end and the discharging end. An auxiliary transfer mechanism is also arranged on the surface of the moving bottom plate, and the auxiliary transfer mechanism is connected to the flipping mechanisms at the feeding end and the discharging end.

[0006] Preferably, the auxiliary transfer mechanism includes a plurality of pulley frames arranged on the surface of the moving bottom plate. All the pulley frames are arranged in sequence along the width direction of the moving bottom plate. Each pulley frame is stepped along the length direction of the moving bottom plate, and a plurality of universal wheels are arranged on the top of each pulley frame.

[0007] Preferably, between the fixed bottom plate and the moving bottom plate, they are slidably connected through a guide rail mechanism arranged on both sides of the fixed bottom plate.

[0008] Preferably, the flipping mechanism includes a cross beam swingably arranged at the feeding end or the discharging end of the moving bottom plate. On the surface of the cross beam, a plurality of support frames are arranged at intervals. On the surface of each support frame, a suction cup frame is respectively arranged. A plurality of suction cups are arranged on the upper part of each suction cup frame.

[0009] Preferably, the support frames are arranged at the gaps between adjacent two pulley frames.

[0010] Preferably, the support frame and the suction cup frame on its surface are connected by auxiliary connecting rods on both sides. Auxiliary connecting rods are respectively arranged at the front and rear ends on each side of the support frame.

[0011] Preferably, all the auxiliary connecting rods at the front ends of all the support frames are connected by a connecting shaft.

[0012] Preferably, driving mechanisms are respectively arranged at the feeding end and the discharging end of the moving bottom plate. The output shafts of the driving mechanisms at both ends are respectively connected to the support frames at the corresponding ends through main connecting rods.

[0013] Preferably, a lifting cylinder is arranged at the bottom of one of the support frames, and the piston rod of the lifting cylinder is connected to the corresponding suction cup frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

After taking the sheet, the auxiliary transfer mechanism is used to realize the transfer of the glass plate. At the same time, the transfer rack is omitted, and the labor intensity is reduced.

[0016] In the upper and lower sheet transfer device of this glass plate, by setting a lifting cylinder, an upward lifting force is applied to the glass plate simultaneously when picking up the sheet, which can avoid the situation where multiple glass plates move simultaneously due to the adhesion of adjacent two glass plates during transfer, thus avoiding danger.

[0021] Figures 1 to 3 is the best embodiment of the present utility model. The following further describes the present utility model in conjunction with the attached Figures 1 to 3 drawings.

[0022] As Figures 1 to 2 shown, an upper and lower sheet transfer device of a glass plate (hereinafter referred to as the transfer device) includes a fixed bottom plate 13. On both sides of the surface of the fixed bottom plate 13, guide rail mechanisms 12 are respectively arranged. The two guide rail mechanisms 12 are arranged along the width direction of the fixed bottom plate 13, and each guide rail mechanism 12 is arranged along the length direction of the fixed bottom plate 13. A moving bottom plate 11 is arranged on the surfaces of the two guide rail mechanisms 12. The moving bottom plate 11 is slidably arranged on the surface of the fixed bottom plate 13 through the guide rail mechanisms 12. The power for the movement of the moving bottom plate 11 can be realized through a structure well-known in the art, such as a linear motor, which will not be elaborated herein.

[0023] On the surface of the moving bottom plate 11, a plurality of pulley frames 14 are arranged at intervals along its width direction, and each pulley frame 14 is arranged along the length direction of the moving bottom plate 11. A number of universal wheels 2 are evenly arranged on the upper surface of each pulley frame 14. In this transfer device, one end is the feeding end and the other end is the discharging end, and the feeding end and the discharging end share the universal wheels 2 at the top of all pulley frames 14. After the glass plate is transferred to the surface of this transfer device from the feeding end, it is transferred to the discharging end through all the universal wheels 2, and then further transferred to the subsequent process by the discharging end.

[0024] The feeding end and the discharging end are symmetrically arranged. Taking the feeding end as an example: On both sides of the end face of the feeding end of the moving bottom plate 11, there is a stretching frame 15 horizontally arranged respectively. At the outer ends of the upper surfaces of the two stretching frames 15, there is a rotating shaft mechanism 10 arranged respectively. On the upper surfaces of the two rotating shaft mechanisms 10, there is a cross beam 9 horizontally arranged. The cross beam 9 is hinged to the surface of the stretching frame 15 through the rotating shaft mechanisms 10 on both sides.

[0025] On the upper surface of the cross beam 9, there are multiple support frames 3 evenly arranged. The support frames 3 are sequentially arranged in the gaps between two adjacent pulley frames 14. The outer ends of all the support frames 3 are fixed on the surface of the cross beam 9. The inner ends of the left and right support frames 3 horizontally extend above the moving bottom plate 11. Above each support frame 3, there is a suction cup frame 1 arranged respectively. On the upper surface of each suction cup frame 1, multiple suction cups 6 are sequentially arranged along its length direction. When the suction cup frame 1 fits with its corresponding support frame 3, the upper surface of the suction cup 6 is lower than the top of the universal wheel 2.

[0026] Between each support frame 3 and the suction cup frame 1 above it, there is a secondary connecting rod 5 connecting them. In each group of corresponding support frames 3 and suction cup frames 1, the secondary connecting rods 5 are respectively arranged on both sides of the support frame 3 and the corresponding suction cup frame 1, and there are two secondary connecting rods 5 respectively arranged on each side of the support frame 3 and the corresponding suction cup frame 1. The lower part of each secondary connecting rod 5 is hinged to the support frame 3, and the upper part is hinged to the corresponding suction cup frame 1.

[0027] The 2N (N is the number of support frames 3) secondary connecting rods 5 on both sides of the front ends of all the support frames 3 are fixed through a connecting shaft 16 penetrating all the support frames 3. Therefore, when any suction cup frame 1 swings above its corresponding support frame 3, it can drive all the suction cup frames 1 to swing synchronously above their respective corresponding support frames 3. At the lower part of one of the support frames 3, there is a lifting cylinder 4. The end of the piston rod of the lifting cylinder 4 is hinged to the corresponding suction cup frame 1 (or hinged through a connecting rod). Therefore, when the lifting cylinder 4 acts, it can drive all the suction cup frames 1 to swing above their respective corresponding support frames 3.

[0028] On the upper surface of the moving bottom plate 11, there is also a driving mechanism 8 arranged. The driving mechanism 8 can be realized through a common driving motor and a reducer. The two output shafts of the driving mechanism 8 respectively extend out from its two sides. At the ends of the two output shafts of the driving mechanism 8, they are respectively hinged to the bottoms of the support frames 3 on both sides through main connecting rods 7.

[0029] The specific working process and working principle are as follows:

[0030] When taking the glass sheet, the moving bottom plate 11 moves towards the glass plate side under the action of the driving device and stops moving when it reaches the end. The driving mechanism 8 works. The output shafts on both sides thereof drive the supporting frames 3 connected thereto to swing respectively through the main connecting rods 7. When the two supporting frames 3 swing, they further drive all the supporting frames 3 to swing through the cross beam 9. At this time, the cross beam 9 and all the supporting frames 3 on its surface swing around the rotating shaft mechanism 10 as the axis.

[0031] After all the supporting frames 3 finish swinging, or during the swinging process, the lifting cylinder 4 acts to make the suction cup holder 1 connected thereto swing on the surface of the corresponding supporting frame 3. As can be seen from the above, at this time, all the suction cup holders 1 swing synchronously on the upper parts of their corresponding supporting frames 3, as Figure 3 shown in the state. When the suction cup holder 1 and the supporting frame 3 swing to the end, the suction cups 6 are attached to the surface of the glass plate. By performing a vacuum pumping operation on all the suction cups 6, all the suction cups 6 adsorb the outermost glass plate.

[0032] Then the lifting cylinder 4 acts first to reset all the suction cup holders 1. At this time, an upward and swinging force is applied to the adsorbed glass plate simultaneously. Under the combined action of the two forces, the adsorbed glass plate is separated from another adjacent glass plate. By the lifting cylinder 4 first providing an upward lifting force to the adsorbed glass plate, it can be avoided that when transporting, due to the adhesion of two adjacent glass plates, the situation where multiple glass plates move simultaneously occurs, thus avoiding danger.

[0033] After the adsorbed glass plate is lifted, the driving mechanism 8 rotates in the reverse direction simultaneously, driving the cross beam 9 and all the supporting frames 3 to reset simultaneously, so that the glass plate is gradually transferred to the upper part of this transfer mechanism in a horizontal state. When the cross beam 9 and all the supporting frames 3 are reset, the vacuum pumping operation on all the suction cups 6 is cancelled. At this time, the suction cups 6 only play a supporting role for the glass plate. And the glass plate is transferred to the upper part of all the universal wheels 2, and the universal wheels 3 support the glass plate. At this time, the suction cups 6 fall to a position lower than the universal wheels 2.

[0034] Then an operator pushes the glass plate towards the output end of this transfer mechanism. After the glass plate is transferred to the output end under the action of all the universal wheels 2. The driving mechanism 8 at the output end acts, driving the cross beam 9 and all the supporting frames 3 to rise simultaneously. After all the suction cups 6 at the output end contact the bottom surface of the glass plate, a vacuum pumping operation is performed on all the suction cups 6 at the output end to adsorb the glass plate.

[0035] Then the moving bottom plate 11 moves towards the subsequent process under the action of the driving device and stops moving when it reaches the end. While the driving mechanism 8 is working (or before or after), the piston rod of the lifting cylinder 4 at the output end outputs, and together with the cross beam 9, makes the glass plate be transferred to the outside of this transfer mechanism and sent to the next process, and so on.

[0036] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
