Description

Technical Field

[0001] The invention relates to the technical field of glass deep processing, and in particular to a glass lowering system for producing hollow glass. Background Art

[0002] After the glass is processed, it needs to be packaged and stored. In order to save the volume occupied by the glass, manufacturers usually stack the glass. When the storage environment of the glass is relatively humid, broken bonds and mildew will appear on the surface of the glass; and when capillary phenomenon occurs between the two pieces of glass, dust particles or moisture in the air are inhaled to produce a chemical reaction, causing the two pieces of glass to stick together, which is difficult to separate when used. Therefore, the glass is isolated by laying spacer paper; the paper laying machine used for laying spacer paper is usually arranged at the end of the production line, and a manipulator or robot grabs the glass and places it on the paper laying platform for laying paper.

[0003] Chinese patent application No. 201710591992.3 discloses a high-speed online paper laying and unloading stacking system for electronic glass, comprising a glass conveying unit, a finished product distribution unit, a manual unloading platform and a mechanical unloading unit arranged in sequence; a glass positioning unit is provided between the glass conveying unit and the finished product distribution unit, and an online paper laying unit is also provided above the glass conveying unit, the online paper laying unit and the finished product distribution unit are connected by an obliquely arranged paper laying belt, a sliding cutter is provided at the feeding port of the paper laying belt, and the belt surface size of the paper laying belt matches the size of the paper to be laid, two sets of transmission mechanisms are provided on the finished product distribution unit, and the transmission directions are respectively directed to the side where the manual unloading platform and the mechanical unloading unit are located, the glass conveying unit and the online paper laying unit are arranged up and down, saving the time for paper laying; the glass that has completed paper laying is transmitted to the manual unloading platform or the mechanical unloading unit, and the glass that has completed paper laying is withdrawn in time, thereby improving production efficiency.

[0004] However, in this technical solution, the glass that has been paper-lined needs to be stacked by a manual unloading table or a mechanical unloading unit, and the glass plates with the spacer paper still need to be transferred to the stacking rack one by one. At the same time, an electrostatic system is often required to apply positive and negative charges to the spacer paper and the glass to enhance the adsorption firmness between the two to ensure that the spacer paper on the glass does not float up during the subsequent unloading process, which limits the improvement effect on the glass unloading stacking process. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and to provide a glass unloading system for the production of insulating glass. By means of carrying parts such as electric suction cups that are grouped on a support conveying track, the carrying parts on the conveying track can transport the glass twice to a packaging stand for stacking during a single cycle of movement. Compared with the unloading operation of picking up the glass one by one by a robotic arm device, the efficiency of glass stacking is improved and the electrostatic adsorption process is replaced, thereby solving the problem of insufficient efficiency of glass stacking unloading.

[0048] (5) The present invention provides a paper loading mechanism, so that the spacer paper loaded in the paper bin rolls down to one end of the paper bin along with the inclined partition, and then the paper rollers are clamped to the barrel shaft of the spacer paper close to each other, and then the paper shifting part picks up the spacer paper wound on the barrel shaft, so that the paper laying machine continues to lay paper; it is convenient to pick up the paper shifting part so as to directly lay paper, thereby reducing the operation of manually replacing the barrel shaft of the spacer paper in the paper laying machine, and further improving the efficiency of stacking glass.

[0065] Embodiment 1

[0066] like Figure 1-5 As shown, this embodiment provides a glass unloading system for insulating glass production, including a paper laying machine 1, and also includes:

[0067] A roller unit 2 for conveying the glass 10 to the paper laying machine 1 is arranged on one side of the paper feeding end of the paper laying machine 1;

[0068] A packaging stand 3 for carrying the glass 10 is arranged between the roller unit 2 and the paper laying machine 1; and

[0069] A stacking unit 4 for stacking the glass 10 on the roller unit 2 onto the packaging rack 3. The stacking unit 4 is arranged between the roller unit 2 and the packaging rack 3;

[0070] The stacking unit 4 comprises:

[0071] A support 41, on which a conveying track 42 is fixed, and the conveying track 42 passes over the packaging stand 3 and the roller unit 2;

[0072] Transport components 43, at least one group of transport components 43 is movably disposed on the conveying track 42; and

[0073] Carrying parts 44, a plurality of carrying parts 44 are respectively fixed on the transport components 43;

[0074] The group of carrying parts 44 are respectively located on the conveying tracks 42 above the roller unit 2 and the packaging stand 3. The transport assembly 43 enables the carrying part 44 above the roller unit 2 to move the grabbed glass 10 to the packaging stand 3. At the same time, after the carrying part 44 above the packaging stand 3 completes stacking of the glass 10, it is reset to the roller unit 2 by the transport assembly 43.

[0075] In this embodiment, by means of the carrying parts 44 such as electric suction cups arranged in groups on the conveying track 42 of the bracket 41, during the process of stacking the glass 10, when the carrying part 44 holding the glass 10 moves to the packaging rack 3, another carrying part 44 arranged in groups completes the stacking of the glass 10 and moves and resets to the roller unit 2 such as the conveyor belt. At the same time, the paper laying machine 1 in this process completes the paper laying action of the glass 10 stacked on the packaging rack 3 once, and so on and so forth, so that the carrying part 44 on the conveying track 42 transports the glass 10 to the packaging rack 3 for stacking twice during the process of completing a single cycle movement, which improves the efficiency of stacking the glass 10 compared with the operation of the robot device picking up the lower pieces of glass 10 one by one;

[0076] It is worth noting that when the glass 10 is stacked on the packaging rack 3, in order to ensure that a stacked glass 10 does not fall and collide with the stacked glass 10 on the packaging rack 3 after the electric suction cup of the carrying part 44 is released, when the transport component 43 arrives above the packaging rack 3, the transport component 43 will drive the carrying part 44 to descend until the transport component 43 detects that the distance to the stacked glass 10 on the packaging rack 3 meets the stacking condition of the glass 10 on the carrying part 44, for example, a distance sensor is installed on the transport component 43 to detect the distance to the top of the stacked glass 10 on the packaging rack 3, and then the electric suction cup of the carrying part 44 releases the glass 10, so that the glass 10 is stacked one by one;

[0077] It is also worth mentioning that traction ropes are connected between the transport components 43 arranged in groups on the conveying track 42, so that the active drive of a single transport component 43 along the conveying track 42 drives the passive movement of other transport components 43 along the conveying track 42, and maintains the distance accuracy between the grouped transport components 43 on the conveying track 42.

[0078] Specifically, Figure 3-4 As shown, the conveying track 42 includes one or more of a reciprocating track 421 in which a single carrying portion 44 is movably provided and arranged in groups, or a loop track 422 in which at least one group of carrying portions 44 is movably provided.

[0079] In this embodiment, for example, the conveying track 42 is arranged as a linear or linear reciprocating track 421, so that the carrying part 44 can only achieve repeated stacking of the glass 10 by reciprocating movement on the conveying track 42; further, the conveying track 42 can also be arranged as a loop track 422 with a closed loop structure, so that the carrying part 44 moves in the same direction to achieve repeated stacking of the glass 10, and the moving path of the carrying part 44 on the conveying track 42 is fully utilized to stack the glass 10 on the roller unit 2 onto the packaging stand 3;

[0080] It is worth noting that if Figure 3 As shown, several groups of roller units 2, packaging racks 3 and paper laying machines 1 can also be arranged on the path of the conveying track 42, and the several roller units 2 arranged in the path of the conveying track 42 can be matched to make the groups of carrying parts 44 arranged at intervals along the loop track 422, and the distance between the carrying parts 44 can match the spacing distance between the several roller units 2 and the several packaging racks 3 on the conveying track 42, so as to achieve stacking of multiple pieces of glass 10 during the process of a single carrying part 44 moving one circle along the conveying track 42.

[0081] Specifically, Figure 6-8 As shown, the transport component 43 includes:

[0082] A connecting portion 431, wherein the connecting portion 431 is movably mounted on the conveying track 42;

[0083] A driving part 432 fixed on the connecting part 431 is drivingly connected to the conveying track 42; and

[0084] The telescopic portion 433 has two ends fixed on the connecting portion 431 and the carrying portion 44 respectively.

[0085] In this embodiment, the driving part 432, such as a track motor, pulls the connecting part 431, such as a block installed on the conveying track 42, to move, so that the glass 10 fixed on the electric suction cup of the carrying part 44 moves to the packaging stand 3, and then the telescopic part 433, such as an electric push rod, extends to lower the glass 10 on the electric suction cup of the carrying part 44, and cooperates with the infrared distance sensor installed on the telescopic part 433 to detect the distance between the glass 10 and the spacer paper laid on the packaging stand 3, so that the glass 10 on the electric suction cup of the carrying part 44 is lowered to the position of contacting the spacer paper for stacking; in this embodiment, the different reflectivity of the glass 10 and the spacer paper to the infrared distance sensor is used to identify the distance to the laid spacer paper;

[0086] Similarly, a stress sensor or a pressure sensor can be installed on the electric suction cup of the carrying part 44, so that when the telescopic part 433 descends, when the glass 10 on the electric suction cup of the carrying part 44 contacts the packaging stand 3 and transfers part of the gravity, the load on the electric suction cup is reduced and detected by the stress sensor or the pressure sensor. At this time, the movement of the telescopic part 433 is stopped and the electric suction cup releases the lower glass 10.

[0087] Specifically, Figure 4 As shown, it also includes an adjustment component 5 for changing the position of the carrying portion 44 relative to the conveying track 42, and the adjustment component 5 includes one or more of a lateral adjustment portion 51 for adjusting the horizontal position or a longitudinal adjustment portion 52 for adjusting the height position.

[0088] In this embodiment, the lateral adjustment part 51 adopts, for example, a truss arranged perpendicular to the travel direction of the conveying track 42, so that the telescopic part 433 in the transport assembly 43 is slidably installed on the connecting part 431 through the truss, and in the reciprocating track 421 or the loop track 422 arranged in groups, the carrying part 44 holding the glass 10 and the vacant carrying part 44 on the adjacent conveying track 42 are intersected and passed, and at the same time, the truss of the lateral adjustment part 51 makes the intersecting carrying parts 44 move away from each other;

[0089] Similarly, the longitudinal adjustment part 52 controls the electric push rod of the telescopic part 433 to shrink the length of the electric push rod less than the length when the glass 10 is grasped after the stacking of the glass 10 is completed, or makes the path height of the conveying track 42 from the packaging stand 3 to the roller unit 2 higher than the path height of the conveying track 42 from the roller unit 2 to the packaging stand 3, so that the carrying parts 44 on adjacent conveying tracks 42 are staggered in height when they meet;

[0090] This avoids interference on the path of the conveying track 42 during the stacking process of the glass 10, and enables the stacking of large-sized glass 10 by the densely arranged conveying tracks 42.

[0091] More specifically, Figure 4 , 6 -8, further comprising a guide assembly 6 for adjusting the running state of the transport assembly 43, the guide assembly 6 being fixedly mounted on the conveying track 42 above the packaging stand 3, and the guide assembly 6 comprising:

[0092] a conductor 61 arranged along the conveying track 42 and forming a loop; and

[0093] The switching part 62 is movably disposed on the connecting part 431 and is used to form a closed loop between the driving part 432 or the telescopic part 433 and the conductor 61 .

[0094] In this embodiment, according to the arrangement of the conveying track 42 and the packaging rack 3 in the unloading system, the guiding assembly 6 is installed accordingly, and the track motor of the driving part 432 and the electric push rod of the telescopic part 433 in the transport assembly 43 are respectively connected to the conductor 61 through the switching part 62. When the transport assembly 43 contacts the guiding assembly 6, the switching part 62 is actuated to disconnect the connection between the conductor 61 and the track motor of the driving part 432, and the operation of the driving part 432 is stopped; similarly, the switching part 62 is actuated to connect the conductor 61 with the electric push rod of the telescopic part 433, thereby controlling the carrying part 44 to descend and stack the glass 10 onto the packaging rack 3;

[0095] It is worth mentioning that the conductor 61 and the switching part 62 can also be used to control the connection status of the driving part 432 and the telescopic part 433 in the transportation component 43, so that the closed loop state formed by the conductor 61 can be controlled as an electrical signal, and then non-electrically driven elements, such as hydraulic motors or cylinders, can be used in the driving part 432 and the telescopic part 433, thereby increasing the applicability of the transportation component 43.

[0096] Specifically, Figure 7-8 As shown, the switching unit 62 includes:

[0097] A positioning member 621, wherein the positioning member 621 is detachably mounted on the conveying track 42 above the packaging stand 3;

[0098] The conductive member 622 is movably disposed on the connecting portion 431 , and the conductive member 622 is provided with electrical contacts 6221 in directions toward the conductor 61 , the driving portion 432 , and the telescopic portion 433 , respectively.

[0099] When the transport component 43 on the conveying track 42 contacts the guide component 6, the conductive member 622 is pushed by the positioning member 621 to slide along the connecting portion 431, so that the electrical contact 6221 of the conductive member 622 is converted from contacting with the conductor 61 and the driving portion 432 respectively to contacting with the conductor 61 and the telescopic portion 433 respectively.

[0100] In this embodiment, the positioning member 621 is fixed on the conveying track 42 above the packaging stand 3. When the transportation component 43 drives the carrying part 44 to move to the position of the guide component 6, the conductive member 622 is interfered by the position of the positioning member 621 on the conveying track 42, and then moves along the connecting part 431. The electrical contacts 6221 on the surface of the conductive member 622 are arranged in pairs, and the area of ​​the electrical contacts 6221 of the conductive member 622 toward the driving part 432 and the telescopic part 433 is smaller than the area of ​​the electrical contacts 6221 toward the conductor 61, so that the sliding transformation of the conductive member 622 in the connecting part 431 maintains the contact state of the electrical contact 6221 with the conductor 61, and the electrical contact 6221 of the conductive member 622 is only in contact with one of the driving part 432 or the telescopic part 433, thereby realizing the control effect of the switching part 62 on the transportation component 43.

[0101] Embodiment 2

[0102] like Figure 1-3 , 9-11, where the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0103] The paper laying machine 1 comprises:

[0104] A traction mechanism 11 for guiding the spacer paper to the surface of the stacked glass 10 is arranged on both sides of the packaging stand 3 and is transmission-connected to the paper laying machine 1;

[0105] A paper loading mechanism 12, which is used to replenish the paper spacer in the paper laying machine 1, is fixedly arranged above the paper laying machine 1; and

[0106] The lifting assembly 13 is fixedly disposed below the traction mechanism 11 and is used to adjust the height of the traction mechanism 11 .

[0107] In this embodiment, after the stacking unit 4 completes stacking of glass 10 each time, the paper feeding end of the paper laying machine 1 will lay paper on the glass 10 stacked on the packaging stand 3, and the spacer paper separated from the paper laying machine 1 will be guided by the traction mechanism 11 to cover the surface of the glass 10. When the spacer paper on the cylinder shaft in the paper laying machine 1 is consumed, the empty cylinder shaft is removed and a new cylinder shaft is loaded through the paper loading mechanism 12. During the paper laying process, the lifting component 13, such as an electric lifting rod, according to the thickness data of the stacked glass 10, after completing the paper laying of the previous piece of stacked glass 10, the traction mechanism 11 is synchronously raised upwards, and then the spacer paper between the traction mechanism 11 and the paper feeding end of the paper laying machine 1 is raised and cut and separated.

[0108] Specifically, Fig.10 As shown, the traction mechanism 11 includes:

[0109] A rotating part 111, which is used for pulling the spacer paper to move toward the surface of the stacked glass 10, is installed on the paper laying machine 1;

[0110] The winding part 112, which is drivingly connected to the rotating part 111, is distributed on both sides of the packaging stand 3; and

[0111] The guide parts 113 , which are used to fix the spacer paper, are fixed on the winding part 112 .

[0112] In this embodiment, the rotating part 111 and the winding part 112 in the traction mechanism 11 can adopt a sprocket and a chain belt mechanism installed on a rod mechanism, and the guide part 113 can adopt an electrostatic strip. When a piece of glass 10 is stacked on the packaging stand 3, the sprocket of the rotating part 111 drives the chain belt of the rotating part to make the electrostatic strip of the guide part 113 sweep back and forth along the surface of the glass 10. At the same time, during the paper laying process, a static electricity removal device is set at the paper outlet end of the paper laying machine 1 to remove static electricity on the spacer paper, and the spacer paper is attached to the surface of the static electricity strip to cover the glass 10. When the winding part 112 continues to operate to make the static electricity strip separate from the glass 10 area, the spacer paper is attached to the surface of the glass 10.

[0113] It should be added that, when the stacked glass 10 is transferred to the outside of the packaging stand 3 , the rod mechanism for installing the traction mechanism 11 is retracted into the paper laying machine 1 , releasing the moving space for the packaging stand 3 .

[0114] Specifically, Fig. 9 , 11 As shown, the paper feeding mechanism 12 includes:

[0115] A paper bin 121 for loading a plurality of spaced paper roll shafts is fixedly arranged on the top of the paper laying machine 1;

[0116] A paper roller 122, which is used to clamp the paper roller 122 of the spacer paper tube shaft and is movably arranged on the side wall at one end of the paper bin 121; and

[0117] The partition 123 is tilted and fixed in the paper bin 121 , and an opening 1230 is formed at the bottom end of the partition 123 and one end of the paper bin 121 , which is larger than the diameter of the partition paper cylinder shaft and smaller than the diameter of the partition paper.

[0118] In this embodiment, when the spacer paper rotated and clamped on the paper roller 122 is used up, the movable paper rollers 122 arranged on the side wall of the paper bin 121 move away from each other, so that the barrel shaft falls and is discharged along the opening 1230 at the bottom end of the partition 123, and the spacer paper loaded in the paper bin 121 rolls down to one end of the paper bin 121 along the inclined partition 123, and then the paper rollers 122 are arranged close to each other and clamped to the barrel shaft of the spacer paper, and then the paper picking part picks up the spacer paper wound on the barrel shaft, so that the paper laying machine 1 continues to lay paper;

[0119] It is worth noting that the rotation direction of the spacer paper loaded in the paper bin 121 is opposite to the rotation direction of the paper roller 122, so that it is convenient to pick up the paper-moving part for direct paper laying, reducing the operation of manually replacing the spacer paper roller shaft in the paper laying machine 1, and further improving the efficiency of stacking the glass 10.

[0120] Embodiment 3

[0121] like Figure 1-3 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The differences between the third embodiment and the first embodiment are as follows:

[0122] It also includes a transfer assembly 31 for transferring the stacked glass 10, and the transfer assembly 31 is fixedly arranged at the bottom of the packaging stand 3;

[0123] The transfer assembly 31 includes a turning portion 311 for adjusting the posture of the packaging stand 3 and a loading portion 312 for receiving and packaging stacked glasses 10 .

[0124] In this embodiment, after the glass 10 on the packaging rack 3 is stacked to the capacity of a packaging unit, the flipping part 311, such as the hydraulic rod group and the slide installed at the bottom of the packaging rack 3, moves the packaging rack 3 to one side to leave the position of the stacking unit and then flips it. At the same time, before the flipping action of the packaging rack 3, the loading part 312, such as the stacking rack installed on the hydraulic rod group, is placed on one side of the packaging rack 3 and contacts the side and upper surface of the stacked glass 10, so that the flipping part 311 cooperates with the loading part 312 to perform synchronous flipping, and the packaged stacked glass 10 is stably transferred out, so as to continue to stack the glass 10 on the packaging rack 3.

[0125] It should be added that Figure 3 As shown, for a lower sheet system having a plurality of groups of roller units 2, a packaging stand 3 and a paper laying machine 1, the mechanisms of the lower sheet system can be suspended so that a lifting space is provided under the packaging stand 3 for the operation of the transfer assembly 31; similarly, a movably arranged roller unit 2 or paper laying machine 1 can be provided on one side of the packaging stand 3, and when the stacking of the glass 10 is completed and needs to be transferred, it can be moved away to serve as a space for the movement of the loading part 312.

[0126] Working steps

[0127] Step 1: When the carrying part 44 holding the glass 10 moves to the packaging rack 3, another carrying part 44 arranged in a group completes the stacking of the glass 10 and moves back to the roller unit 2 such as the conveyor belt. At the same time, the paper laying machine 1 completes the paper laying action of the glass 10 stacked on the packaging rack 3 once, and repeats this process, so that the carrying part 44 on the conveying track 42 transports the glass 10 to the packaging rack 3 for stacking twice in the process of completing a single cycle of movement;

[0128] Step 2: When the transport component 43 arrives above the packaging rack 3, the transport component 43 drives the carrying part 44 to descend until the transport component 43 detects that the distance to the stacked glasses 10 on the packaging rack 3 meets the stacking condition of the glasses 10 on the carrying part 44. For example, a distance sensor is installed on the transport component 43 to detect the distance to the top of the stacked glasses 10 on the packaging rack 3, and then the electric suction cup of the carrying part 44 releases the glasses 10, so that the glasses 10 are stacked one by one.

[0129] Step 3: When the glass 10 fixed on the electric suction cup of the carrying part 44 moves to the packaging stand 3, the telescopic part 433, such as the electric push rod, is extended to lower the glass 10 on the electric suction cup of the carrying part 44, and the infrared distance sensor installed on the telescopic part 433 detects the distance between the glass 10 and the spacing paper laid on the packaging stand 3, so that the glass 10 on the electric suction cup of the carrying part 44 is lowered to the position of contacting the spacing paper for stacking;

[0130] Step 4: When the carrier 44 holding the glass 10 and the vacant carrier 44 on the adjacent conveying track 42 intersect and pass by, the truss of the lateral adjustment part 51 makes the intersecting carriers 44 move away from each other; the longitudinal adjustment part 52, for example, controls the electric push rod of the telescopic part 433 to make the contraction length after completing the stacking of the glass 10 smaller than the length when holding the glass 10, so that the carriers 44 on the adjacent conveying tracks 42 are staggered in height when intersecting;

[0131] Step 5: When the transport component 43 contacts the guide component 6, the switch unit 62 is actuated to disconnect the conductor 61 from the track motor of the drive unit 432, and the operation of the drive unit 432 is stopped; then the switch unit 62 is actuated to connect the conductor 61 to the electric push rod of the telescopic unit 433, and then the carrying unit 44 is controlled to descend to stack the glass 10 onto the packaging rack 3;

[0132] Step six, when the transport component 43 drives the carrying part 44 to move to the position of the guide component 6, the conductive member 622 is interfered by the position of the positioning member 621 on the conveying track 42, and then moves along the connecting part 431, so that the sliding transformation of the conductive member 622 in the connecting part 431 maintains the contact state of the electrical contact 6221 and the conductor 61, and the electrical contact 6221 of the conductive member 622 is only in contact with one of the driving part 432 or the telescopic part 433, thereby realizing the precise control of the switching part 62 over the transport component 43.

[0133] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
