Description

Technical Field

[0001] The invention relates to the technical field of annealing conveying devices, and in particular to a glassware annealing conveying device and a conveying method. Background Art

[0002] Glass products may crack during the annealing process. Some of the cracking is caused by excessive tensile stress at the edge of the glass plate, that is, the edge is too tight. In the annealing position, if the temperature of the edge of the glass plate is too high than the temperature in the middle, longitudinal cracking will occur. In addition, if there are foreign objects in the glass, it will cause transverse cracking.

[0003] Chinese patent CN220182037U discloses a broken glass cleaning device for an annealing position of a glass production line. A guide plate with a slope is arranged at the bottom of a collecting hood, and the broken glass is guided to discharge ports on both sides by the guide plate. Two groups of scrapers that can move synchronously to the front and rear sides to scrape out the broken glass are arranged above the guide plate, ensuring that the broken glass can be quickly and synchronously scraped out to the front and rear sides, making cleaning more convenient, avoiding the safety hazard of manually drilling under a conveyor frame for cleaning, making it safer to use, and having higher cleaning efficiency.

[0004] The above-mentioned device collects broken glass by setting up multiple groups of collecting hoods. However, in actual use, when the length of the annealing furnace is long, the number of collecting hoods arranged will increase accordingly, making the overall device more complicated. In addition, when glass breaks in the annealing furnace, it is unclear where the glass is broken in the annealing furnace. Therefore, it is difficult to clean the broken glass in time through this device. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a glassware annealing conveying device and a conveying method to solve the above technical problems. Summary of the invention

When the partition is aligned with a partition below the chain as the chain moves, the sliding rod below can be driven to slide outward relative to the rod sleeve through the extrusion of the upper and lower inclined plates, so that the clamping assembly on the fixed frame below is disconnected from the scraper.

[0009] As a further solution of the present invention: the rod sleeve is fixedly connected to the fixed frame through a support rod.

[0010] As a further solution of the present invention: openings and through slots connected to the openings are arranged on both sides of the annealing furnace, and the through slots are arranged in a T-shape.

On the other hand, it also avoids the scraper from contacting and rubbing with the bottom plate for a long time. Only when the glassware is broken, the corresponding scraper will fall to the bottom plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] like Figure 1-Figure 5 As shown, a glassware annealing conveying device and conveying method include two chains 4 arranged opposite to each other, a partition 1 for carrying glassware is installed between the two chains 4, and a plurality of through holes are evenly opened on the partition 1. Specifically, in order to connect the partition 1 with the chain 4, the present solution is provided with a fixing frame 5 on the outer side of the partition 1, and the fixing frame 5 is fixedly installed between the two chains 4. The installation of a rigid member between the two chains 4 is a mature technical means in the mechanical field, and its specific installation structure is not described in detail here.

[0032] An annealing station is provided at a certain section of the chain 4. Specifically, an annealing furnace 2 is provided at the annealing station. A heating unit is provided in the annealing furnace 2 to keep the glassware warm, thereby eliminating the stress on the glassware. However, in actual use, it is still inevitable that the glassware will break. In order to clean the broken glass, a scraper 7 is slidably provided on one side of the fixed frame 5 in this solution.

[0033] Further, a rod sleeve 9 is provided on the inner side of the partition 1, the rod sleeve 9 is connected to the fixed frame 5, and a sliding rod 8 is elastically installed at one end of the rod sleeve 9 away from the partition 1, the sliding rod 8 is arranged in an L shape, and a top plate 10 is fixedly provided at one end of the sliding rod 8 located outside the rod sleeve 9, and inclined plates 1001 are fixedly provided on both sides of the top plate 10, the inclined plates 1001 are inclined, and the end of the inclined plate 1001 away from the top plate 10 is deflected in a direction away from the sliding rod 8, referring to Figure 2-Figure 3 As shown, the top plates 10 located at the upper and lower parts of the chain 4 are on the same vertical plane, that is, as the chain 4 rotates, the top plates 10 on the upper and lower sides can overlap on the vertical plane. Figure 3As shown, the center line of the chain 4 is marked as m, the top plate 10 located at the upper part of the chain 4 is below the line m, and the top plate 10 located at the lower part of the chain 4 is above the line m. Through this setting, in the initial state, the upper and lower top plates 10 will not contact or squeeze each other during the relative movement.

[0034] The fixed frame 5 is provided with a clamping assembly that cooperates with the scraper 7. In actual use, when the glassware on the upper partition 1 is broken, the gravity on the partition 1 will be reduced, so that the sliding rod 8 connected to the partition 1 can be retracted into the rod sleeve 9, so that the top plate 10 connected to the partition 1 can cross the line m. After that, the partition 1 will be aligned with a partition 1 below the chain 4 during the movement of the chain 4. During this process, the inclined surfaces on the upper and lower top plates 10 will contact and squeeze, thereby driving the sliding rod 8 connected to the lower partition 1 to slide outward relative to the rod sleeve 9. When the sliding rod 8 slides outward relative to the rod sleeve 9 to disconnect the clamping assembly from the scraper 7, the scraper 7 can slide downward relative to the fixed frame 5, which is beneficial to cleaning the glass debris in the annealing furnace 2.

[0035] Reference Figure 1-Figure 7 , Fig. 9 As shown, openings 204 are provided on both sides of the annealing furnace 2 so that glassware placed on the partition 1 can enter and exit the annealing furnace 2. In addition, through grooves 203 connected to the openings 204 are provided on both side surfaces of the annealing furnace 2. The through grooves 203 are arranged in a T shape, and through this structure, the upper and lower sliding rods 8 and the rod sleeves 9 and other structures can enter and exit the annealing furnace 2.

[0036] A bottom plate 202 is fixedly provided near the bottom end inside the annealing furnace 2, and the top surface of the bottom plate 202 is aligned with the bottom surface of the through groove 203. In actual use, when the scraper 7 slides downward relative to the fixed frame 5, it can fall onto the bottom plate 202, thereby pushing the broken glass on the bottom plate 202 to the outside of the annealing furnace 2 through the through groove 203.

[0037] A slide bar 14 is fixedly arranged on one side of the scraper 7 close to the fixed frame 5, and a slide groove slidably matched with the slide bar 14 is provided on the side of the fixed frame 5, and the cross-sections of the slide groove and the slide bar 14 are both set to be T-shaped. The above-mentioned clamping assembly includes a clamping block 20 elastically connected to the fixed frame 5, and a clamping groove matched with the clamping block 20 is provided on the slide bar 14. When the clamping block 20 is in a pop-up state and inserted into the clamping groove, the scraper 7 is confined to one side of the fixed frame 5;

[0038] Furthermore, a slide plate 16 is slidably arranged in the rod sleeve 9, and the slide plate 16 is made of iron, and a connecting rod 17 is fixedly arranged between the slide plate 16 and the slide bar 8. In addition, a fixed block 11 is fixedly arranged in the rod sleeve 9, so that the connecting rod 17 passes through the fixed block 11 and slidably cooperates with it, and a limit spring is fixedly arranged between the fixed block 11 and the slide bar 8, so as to achieve elastic cooperation between the slide bar 8 and the rod sleeve 9. The purpose of fixing the limit spring between the slide bar 8 and the slide plate 16 here is: when the partition 1 is in the lower half of the chain 4, the slide bar 8 on one side of the partition 1 can be supported by the limit spring, and when the partition 1 is in the upper half of the chain 4, the slide bar 8 on one side of the partition 1 can be pulled by the limit spring, so that the top plates 10 on the upper and lower slide bars 8 can be located at the positions on both sides of the line m;

[0039] A pull rope 12 is fixedly arranged between the slide plate 16 and the clamping block 20 . The pull rope 12 passes through the rod sleeve 9 , the partition plate 1 and the fixing frame 5 and can slide relative to the rod sleeve 9 , the partition plate 1 and the fixing frame 5 .

[0040] In actual use, a ring-shaped electromagnet 13 is fixedly installed at the bottom end of the rod sleeve 9. The electromagnet 13 is located on the side of the slide plate 16 away from the fixed block 11. When the electromagnet 13 is energized, it can attract the slide plate 16, thereby driving the slide bar 8 to slide into the rod sleeve 9. Specifically, when the glassware on the partition 1 is broken, the pressure on the partition 1 is reduced, and the electromagnet 13 is in a energized state.

[0041] During the annealing process, the glassware is placed on the partition 1, and the partition 1 and the fixed frame 5 are moved by the chain 4, so that the glassware is driven into the annealing furnace 2 for annealing. When the glassware on a partition 1 located in the upper part of the chain 4 is broken, the pressure on the partition 1 will be reduced, so that the electromagnet 13 in the rod sleeve 9 installed on one side of the partition 1 can be in an energized state, and the suction force between the electromagnet 13 and the slide plate 16 can pull the slide bar 8 to slide in the direction of the rod sleeve 9, so that the top plate 10 at one end of the slide bar 8 can cross the line m, and as the chain 4 rotates, the partition 1 carrying the broken glass will be in contact with a partition 1 in the lower part of the chain 4. Gradually overlap, during which the inclined plates 1001 on the upper and lower top plates 10 will contact and squeeze each other. Since the upper slide bar 8 is attracted by the electromagnet 13, when the upper and lower inclined plates 1001 are squeezed, the slide bar 8 connected to the lower partition plate 1 can be driven to move in a direction away from the rod sleeve 9, so that the block 20 can be pulled by the pull rope 12, so that one end of the block 20 is moved out of the slot. After the block 20 is separated from the slot, the scraper 7 can slide downward relative to the fixed frame 5 and contact the bottom plate 202. When the scraper 7 moves with the fixed frame 5, the scraper 7 can be used to push the glass debris falling on the bottom plate 202 to one side of the annealing furnace 2 and finally lead it out through the through slot 203.

[0042] When the two top plates 10 are offset, the slide bar 8 connected to the lower partition 1 will be reset. When the chain 4 drives the partition 1 to move to the end of the chain 4 and flip over, the scraper 7 will be reset under the action of gravity. When the block 20 coincides with the slot, the block 20 can be reinserted into the slot, which is conducive to its reuse. At the same time, when the electromagnet 13 at the upper partition 1 loses power, the slide bar 8 can also be reset, which is conducive to its subsequent use.

[0043] In summary, this device is provided with a scraper 7 on one side of the fixed frame 5. When the glass on a partition 1 is broken, the scraper 7 on the partition 1 located at the lower half of the chain 4 and overlapping with the partition 1 can fall onto the bottom plate 202. Through this structure, on the one hand, the position of the broken glass can be located, so that the scraper 7 can push the broken glass out of the annealing furnace 2 in time, which is beneficial to ensure the normal annealing of the remaining glassware. On the other hand, it also avoids the scraper 7 from contacting and rubbing with the bottom plate 202 for a long time. Only when the glassware is broken, the corresponding scraper 7 will fall onto the bottom plate 202.

[0044] like Figure 4 , Figure 6-Figure 10 As shown, bosses 6 are fixedly provided at the corners of the fixed frame 5, and a positioning rod 19 is fixedly provided between the upper and lower bosses 6, and the positioning rod 19 passes through the partition 1 and slidably cooperates with the partition 1;

[0045] When the pressure on the partition 1 decreases, the electromagnet 13 is in a powered state. In order to achieve this process, two embodiments are provided in this scheme:

[0046] The first embodiment: a pressure sensor is installed on the top surface of the lower boss 6 to detect the pressure change on the partition 1. Here, the distance between the partition 1 and the boss 6 is small. The pressure sensor can be connected to the electromagnet 13 through a programmer or a controller (PLC or single-chip microcomputer, etc.). When the pressure on the partition 1 decreases, the pressure sensor can detect this signal and trigger the electromagnet 13 to put it in a powered state. Of course, a time relay can also be installed between the pressure sensor and the electromagnet 13, so that the electromagnet 13 can be powered and then be powered again.

[0047] Second embodiment: mounting grooves can be provided on both side surfaces of the partition 1, and a blocking block 22 is fixedly provided on the inner wall of the mounting groove, and a detection unit 23 is embedded on the inner wall of the fixed frame 5. The detection unit 23 can be an infrared sensor, etc. In actual use, a support spring is sleeved on the outer side of the positioning rod 19, and the support spring is located between the partition 1 and the lower boss 6. The above-mentioned detection unit 23 can be connected with the electromagnet 13 through a signal. In actual use, when the pressure on the partition 1 is reduced, the partition 1 can move upward relative to the positioning rod 19. During this process, the blocking block 22 will pass through the infrared sensor, so that the infrared sensor can detect this signal and trigger the electromagnet 13 to put it in an energized state. Of course, a time relay can also be installed between the detection unit 23 and the electromagnet 13, so that the electromagnet 13 can be in a de-energized state again after being energized for a period of time. When the partition 1 flips to the bottom with the chain 4, since the detection unit 23 and the blocking block 22 are always in a staggered state, the electromagnet 13 located in the lower half of the chain 4 can always be in a de-energized state.

[0048] The method of controlling the electromagnet 13 by detecting pressure changes is a mature technical means in the electrical field, and its working principle and circuit connection are not described in detail here.

[0049] like Figure 1-Figure 5 As shown, sprockets are provided at both ends of the chain 4, and support columns are provided on the outer sides of the sprockets. Specifically, a rotating shaft is fixedly provided on the sprocket, and the rotating shaft passes through the support column and is rotatably connected thereto. In actual use, a motor is installed on one of the support columns, and the rotating shaft passes through one end of the support column and is transmission-connected to the output shaft of the motor, thereby driving the chain 4 to rotate.

[0050] Sealing plates 3 are provided on both sides of the annealing furnace 2 . The sealing plates 3 are located at the opening 204 and can move in the vertical direction. In actual use, the sealing plates 3 can be driven to move up and down by a traction mechanism such as a winch, so as to close the opening 204 .

[0051] like Figure 6 As shown, a support rod 15 is fixedly arranged between the rod sleeve 9 and the fixed frame 5;

[0052] The partition 1 is provided with a rope groove at the pull rope 12 , which is conducive to the movement of the pull rope 12 relative to the partition 1 .

[0053] like Figure 5 As shown, a support bar 201 is fixedly installed on the inner wall of the annealing furnace 2 , and the support bar 201 is located below the chain 4 for supporting the chain 4 .

[0054] like Figure 7 As shown, an annular plate 18 is fixedly provided on the outer surface of the partition 1, and an annular groove slidably connected to the annular plate 18 is provided on the boss 6. The annular plate 18 is sealed with the annular groove, and a guide hole connected to the annular groove is provided on the boss 6. Through this structure, the partition 1 can have a buffer when moving, making its movement smoother.

[0055] like Figure 6 , Figure 8 As shown, a guide plate 21 is fixedly sleeved on the outer side of the slide rod 8, and a guide groove is provided on the guide plate 21. The guide groove is arranged along the thickness direction of the guide plate 21, and a notch that slides with the guide plate 21 is provided on the inner wall of the rod sleeve 9. Through this structure, there is a buffer when the slide rod 8 moves relative to the rod sleeve 9, which is conducive to the stable movement of the slide rod 8.

[0056] like Fig. 9 As shown, a groove for slidingly cooperating with the clamping block 20 is provided on the inner wall of the fixing frame 5 , and a spring is fixedly arranged between the inner end surface of the groove and the clamping block 20 .
