Description

Technical Field

[0001] The present application relates to the technical field of bottle spraying, and in particular to an automatic feeding system for producing spray-coated and baked glass containers. Background Art

[0002] At present, the sensory quality of glass containers has been significantly improved after deep processing such as imitation pottery, baking, frosting, etc., and they are deeply favored by the market. The spraying manufacturing of glass containers generally includes the following steps: surface treatment, spraying, drying, decals, baking, etc. In order to improve the production efficiency of glass containers, it is often necessary to use a dedicated spraying and baking production line to spray and bake glass containers.

[0003] In the related technology, a Chinese patent with announcement number CN209006032U proposes a glass bottle spraying production system, which includes a conveying device arranged in a loop, the conveying device is driven by a motor to move along the loop, the glass bottles are rotatably and evenly fixed on the conveying device, and the glass bottles are pressed and fixed on the conveying device; the conveying device is provided with a loading area, a pre-treatment device, a glass bottle fastening device, a spraying device, a drying device and a unloading area in sequence along the conveying direction, and the conveying device passes through the interior of the pre-treatment device, the glass bottle fastening device, the spraying device and the drying device; the conveying device is evenly provided with transmission rod slots, the transmission rods are inserted into the transmission rod slots, and a fixing seat is provided on the transmission rod, the fixing seat is used to fix the glass bottles, and the transmission rod slots are rotatably fixed on the conveying device.

[0004] The above-mentioned related technologies have the following defects: when using a conveying device to transport glass bottles, it is necessary to manually turn the glass bottles upside down on the transmission rod. In this case, the glass bottles can be stably fixed on the transmission rod under the drive of the glass bottle fastening device and rotate synchronously with the transmission rod. In addition, the conveying device can sequentially transfer the glass bottles to the spraying device, the drying device and the unloading area through the transmission rod, thereby completing the spraying process of the glass bottles. Considering that the conveying device is constantly moving in a circular direction, and the bottle mouth of the glass bottle is small in diameter, it is difficult to align the glass bottle and turn it upside down on the transmission rod, which in turn affects the feeding efficiency of the glass bottle. Summary of the invention

[0005] In order to improve the problem of low feeding efficiency of glass containers, the present application provides an automatic feeding system for the production of spray-coated and baked glass containers.

[0006] The automatic feeding system for producing spray-coated and baked glass containers provided in this application adopts the following technical solution:

[0007] An automatic feeding system for producing spray-coated and baked glass containers is arranged in the feeding area of ​​a glass container spray-coating production line, comprising:

[0008] A conveyor line, used for directional transmission of glass containers one by one, wherein a pair of limit plates for limiting the deflection of the glass containers are arranged on the conveyor line;

[0009] A plug-in mechanism is arranged at the end of the conveying line, and the plug-in mechanism includes a plug-in rod and a positioning seat. The plug-in rod is arranged perpendicular to the positioning seat, and one end of the plug-in rod away from the positioning seat extends between a pair of limit plates and is aligned with the bottle mouth of the glass container; and

[0010] The transfer mechanism is arranged on the side of the plug-in mechanism away from the conveying line and is used to clamp the transfer plug-in rod, so that the glass container is removed from the conveying line and stably placed vertically on the glass container spraying production line through the plug-in rod and the positioning seat.

[0011] Furthermore, a rack for placing the splicing rods and the positioning seats is provided below the conveyor line, and the splicing mechanism also includes a delivery component for transferring and delivering the positioning seats and splicing rods on the rack to the end of the conveyor line.

[0012] Furthermore, the delivery component includes a vertically arranged annular transmission line, a control system for driving the annular transmission line to start and stop, a mounting plate fixed on the annular transmission line and a clamping claw arranged on the mounting plate, and the positioning seat is clamped and adapted with the clamping claw. When the annular transmission line drives the positioning seat and the plug-in rod to move to the end of the conveyor line through the clamping claw, the plug-in rod can be aligned with the bottle mouth of the glass container, so that the glass container is sleeved on the plug-in rod under the transmission of the conveyor line, thereby completing the rapid loading of the glass container; when the annular transmission line drives the positioning seat and the plug-in rod to move to the top of the conveyor line through the clamping claw, the transfer mechanism can clamp the plug-in rod and positioning seat with the glass container and remove them from the clamping claw to the glass container spraying production line.

[0013] Furthermore, a distance sensor for monitoring the position of glass containers on the conveyor line is provided on the frame of the circular transmission line. The control system is electrically connected to the distance sensor. The distance sensor can adjust the rotation speed of the circular transmission line through the control system, so that before the glass container is transmitted to the end of the conveyor line, the circular transmission line has transferred the positioning seat and the plug-in rod on the rack and delivered them to the end of the conveyor line.

[0014] Furthermore, a visual sensor is provided at the end of the plug-in rod, and the visual sensor is electrically connected to the control system. The visual sensor controls the start and stop of the ring transmission line through the control system until the visual sensor detects that the end of the plug-in rod is aligned with the bottle mouth of the glass container.

[0015] Furthermore, an expansion and contraction part and an in-place switch are provided at one end of the plug-in rod away from the positioning seat. The in-place switch is electrically connected to the expansion and contraction part. When the mouth of the glass container is sleeved on the plug-in rod and the in-place switch is triggered, the in-place switch drives the expansion and contraction part to expand, so that the glass container is stably sleeved on the end of the plug-in rod.

[0016] Furthermore, the limit plate is adjustably arranged along the width direction of the conveyor line.

[0017] Furthermore, the transfer mechanism includes a manipulator and an image collector, and the image collector is electrically connected to the manipulator. When the image collector detects that the circular transmission line transfers the glass container to a vertical state, the image collector drives the manipulator to clamp the plug-in rod and the positioning seat with the glass container and remove them from the claws to the glass container spraying production line.

[0018] In summary, the beneficial technical effects of the present application are as follows: by adjusting the limit plate, the glass container can be stably and directed by the conveyor line, the plug rod is placed at the end of the conveyor line and aligned with the bottle mouth of the glass container, so that the glass container can be automatically sleeved on the plug rod under the transmission of the conveyor line, so that the plug rod can stably support the glass container. Then the transfer mechanism can clamp the transfer plug rod, so that the glass container is removed from the conveyor line and stably placed vertically on the glass container spraying production line through the plug rod and the positioning seat, reducing the manual operation of aligning and plugging the glass container onto the plug rod, making the installation and loading efficiency of the glass container higher, thereby improving the loading efficiency of the glass container during the spraying process.

DETAILED DESCRIPTION

[0024] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0025] The present application embodiment discloses an automatic feeding system for producing spray-coated and baked glass containers. Figure 1 and Figure 2 An automatic feeding system for producing spray-coated and baked glass containers is arranged in the feeding area of ​​the glass container spray-coating production line, and includes a conveyor line 1 for directional transmission of glass containers one by one, a plug-in mechanism arranged at the end of the conveyor line 1, and a transfer mechanism arranged on the side of the plug-in mechanism away from the conveyor line 1. Considering that the glass container needs to be erected upside down when spraying, the plug-in mechanism includes a plug-in rod 3 and a positioning seat 4. The plug-in rod 3 is arranged perpendicular to the positioning seat 4, and the end of the plug-in rod 3 away from the positioning seat 4 points to the conveyor line 1, and the bottle mouth of the glass container also faces the direction of the plug-in rod 3. Under the transmission of the conveyor line 1, the glass container can move toward the plug-in rod 3, so that the plug-in rod 3 is inserted into the glass container through the bottle mouth of the glass container. The transfer mechanism can clamp the transfer plug rod 3, so that the glass container is removed from the conveyor line 1 and is stably placed vertically on the glass container spraying production line through the plug rod 3 and the positioning seat 4. In order to prevent the glass container from tipping over during transportation on the spraying production line, a fixing part for fixing the positioning seat 4 is provided between the spraying production line and the positioning seat 4. In a feasible embodiment, the fixing part can be a clamping seat provided on the spraying production line, and the clamping seat can clamp and fix the positioning seat 4, so that the plug rod 3 is vertically mounted on the spraying production line; in another feasible embodiment, the fixing part is a pair of magnetic suction plates provided between the spraying production line and the positioning seat 4, the patch is fixed on the spraying production line, and the magnetic suction plate is fixed on the side wall of the positioning seat 4 away from the plug rod 3, so that under the action of the pair of magnetic suction plates, the plug rod 3 can be vertically mounted on the spraying production line.

[0026] In order to make the glass container be aligned and smoothly sleeved on the plug rod 3 under the transmission of the conveyor line 1, refer to Figure 1 and Figure 3A pair of limit plates 2 for limiting the deflection of glass containers are provided on the conveyor line 1. The glass container is located between the pair of limit plates 2. Considering that glass containers of different sizes have different outer diameters, the limit plates 2 are adjustable along the width direction of the conveyor line 1. An adjusting screw 18 is installed between the baffles on both sides of the conveyor line 1. The length direction of the adjusting screw 18 is consistent with the width direction of the conveyor line 1. The two limit plates 2 are slidably sleeved on the adjusting screw 18. Two pairs of positioning nuts 19 are also threadedly sleeved on the adjusting screw 18. The two pairs of positioning nuts 19 correspond to the two limit plates 2 one by one and are located on both sides of the limit plates 2. When in use, the two limit plates 2 can be adjusted according to the outer diameter of the glass container and the position of the plug rod 3 when pointing to the conveyor line 1, and the limit plates 2 are locked and positioned by the positioning nuts 19, so that the glass container can be quickly aligned and sleeved on the plug rod 3 as the conveyor line 1 is transmitted under the limiting action of the two limit plates 2.

[0027] Since the glass containers are mass-produced during spraying, it is necessary to continuously sleeve the glass containers on the plug-in rod 3. Figure 1 , Figure 2 and Figure 3 , a rack for placing the splicing rod 3 and the positioning seat 4 is provided below the conveyor line 1, and the splicing mechanism also includes a delivery assembly for transferring the positioning seat 4 and the splicing rod 3 on the rack and delivering them to the end of the conveyor line 1. In order to realize automatic feeding production, the delivery assembly includes a vertically arranged annular transmission line 6, a control system 7 for driving the annular transmission line 6 to start and stop, a mounting plate 8 fixed on the annular transmission line 6, and a clamping claw 9 provided on the mounting plate 8. The annular transmission line 6 is vertically arranged at the end of the conveyor line 1, and the control system 7 includes a driving motor and a control module. The control module can adjust the start and stop and the speed of the driving motor so that the annular transmission line 6 can operate and transmit at a suitable speed. The mounting plate 8 is fixedly installed on the annular transmission line 6 and can be raised and lowered together with the annular transmission line 6. Support rods are vertically installed at both ends of the mounting plate 8, and the support rods are located on the side of the mounting plate 8 away from the annular transmission line 6. Two claws 9 are provided, and the two claws 9 are fixedly mounted on the two support rods respectively. For the convenience of the claws 9, in the embodiment of the present application, the claws 9 are set to be C-shaped, and when the claws 9 are located between the annular transmission line 6 and the conveying line 1, the opening of the C-shaped claws 9 faces upward.

[0028] Reference Figure 1 , Figure 2 and Figure 3, the storage rack is set as a conveyor belt 5, the positioning seat 4 is located between the plug rod 3 and the annular transmission line 6, and the length direction of the plug rod 3 is consistent with the conveying direction of the conveyor belt 5, and the conveyor belt 5 can convey the plug rod 3 and the positioning seat 4 one by one in the direction of the annular transmission line 6. After the conveyor belt 5 conveys the plug rod 3 and the positioning seat 4 to a position close to the annular transmission line 6, and the positioning seat 4 extends out of the conveyor belt 5, the annular transmission line 6 rotates, which can drive the claw 9 to rise, so that the two ends of the positioning seat 4 are respectively clamped into the two claws 9, and as the claws 9 rise, the positioning seat 4 and the plug rod 3 are driven to rise synchronously. In order to prevent the positioning seat 4 from rotating in the claw 9 when the claw 9 lifts the positioning seat 4, so that the plug rod 3 cannot be level, the positioning seat 4 is set as a quadrangular prism structure, and the claw 9 is clamped and adapted to the positioning seat 4. In order to ensure that the clamping claw 9 can lift the positioning seat 4 and the plug-in rod 3 to the height of the conveyor line 1, so that the plug-in rod 3 can be aligned with the bottle mouth of the glass container above the conveyor line 1, the distance from the end of the conveyor belt 5 to the annular transmission line 6 is smaller than the distance from the end of the conveyor line 1 to the annular transmission line 6, and the end of the limit plate 2 is extended out of the end of the conveyor line 1. As the clamping claw 9 lifts the plug-in rod 3 and the positioning seat 4, the plug-in rod 3 can move from below the conveyor line 1 to above the conveyor line 1, and the end of the plug-in rod 3 away from the positioning seat 4 extends between a pair of limit plates 2, so that when the bottle mouth of the glass container is sleeved on the plug-in rod 3 during the process of conveying the glass container, the bottle mouth of the glass container extends out of the conveyor line 1, but the bottle body of the glass container is still located on the conveyor line 1.

[0029] To further ensure that the plug rod 3 can be aligned with the mouth of the glass container, it is necessary not only to ensure that the plug rod 3 is at the same height as the mouth of the glass container in the height direction, but also to ensure that the plug rod 3 is aligned with the mouth of the glass container in the horizontal direction. Figure 1 , Figure 3 and Figure 4 The conveyor belt 5 is provided with a limiting groove 16, which is arranged circumferentially along the transmission direction of the conveyor belt 5. The positioning seat 4 is provided with a limiting block 17 that is engaged with the limiting groove 16. When the conveyor belt 5 is transmitting the plug rod 3 and the positioning seat 4, the limiting block 17 is located in the limiting groove 16, so that the positioning seat 4 is not easy to move along the width direction of the conveyor belt 5 on the conveyor belt 5; after the position adjustment of the limiting plate 2 is completed, the claw 9 can lift the positioning seat 4 and the plug rod 3 to the top of the conveyor line 1 and align with the bottle mouth of the glass container on the conveyor line 1, so that the glass container is sleeved on the plug rod 3 under the transmission of the conveyor line 1, and the glass container is quickly loaded.

[0030] Reference Figure 1 and Figure 2A distance sensor 10 is installed on the frame of the circular transmission line 6 through the frame body. The distance sensor 10 is located on the side of the circular transmission line 6 close to the conveyor line 1. The distance sensor 10 can monitor the position of the glass container on the conveyor line 1. The control system 7 is electrically connected to the distance sensor 10. The distance sensor 10 can adjust the rotation speed of the circular transmission line 6 through the control system 7, so that before the glass container is transmitted to the end of the conveyor line 1, the circular transmission line 6 drives the claw 9 to lift the positioning seat 4 and the plug rod 3 on the conveyor belt 5 to the top of the conveyor line 1 and align them with the bottle mouth of the glass container until the bottle mouth of the glass container is sleeved on the plug rod 3.

[0031] In order to monitor the relative position of the plug rod 3 and the glass container, refer to Figure 1 , Figure 2 and Figure 4 A visual sensor 11 is provided at the end of the plug-in rod 3. The visual sensor 11 is installed at the center of the end of the plug-in rod 3. The visual sensor 11 is electrically connected to the control system 7. The visual sensor 11 controls the start and stop of the circular transmission line 6 through the control system 7 until the visual sensor 11 detects that the end of the plug-in rod 3 is aligned with the bottle mouth of the glass container.

[0032] In order to ensure that the glass container can be stably inserted and fixed on the insertion rod 3, refer to Figure 1 , Figure 2 and Figure 4 , an expansion and contraction part 12 and an in-place switch 13 are provided at one end of the plug-in rod 3 away from the positioning seat 4, the expansion and contraction part 12 is configured as an electric airbag, and the in-place switch 13 is configured as an infrared sensing switch; when the conveyor line 1 pushes the glass container to be sleeved on the plug-in rod 3, as the glass container continues to be inserted, when the in-place switch 13 detects the bottle mouth of the glass container, the in-place switch 13 can trigger the expansion and contraction part 12 to start, so that the electric airbag expands, so that the glass container is stably mounted on the plug-in rod 3, ensuring that when the transfer mechanism clamps the plug-in rod 3 for transfer, the glass container can be synchronously and stably transferred to the spraying production line.

[0033] For the setting of the transfer mechanism, refer to Figure 1The transfer mechanism includes a manipulator 14 and an image collector 15. The image collector 15 is electrically connected to the manipulator 14. Considering that the claw 9 is set in a C shape, the circumferential transmission line 6 drives the positioning seat 4 to be lifted through the claw 9. When the claw 9 moves to the top of the circumferential transmission line 6, the positioning seat 4 is easy to fall from the opening of the claw 9, so the image collector 15 is set above the circumferential transmission line 6; when the image collector 15 detects that the claw 9 drives the positioning seat 4 to move above the circumferential transmission line 6, the image collector 15 drives the manipulator 14 to start, so that the manipulator 14 clamps the plug rod 3 with the glass container and moves it out of the opening of the claw 9. At this time, the plug rod 3 and the glass container are in a vertical state, and the manipulator 14 can stably place the positioning seat 4 on the spraying production line, so that under the action of the fixing member, the glass container can be stably and vertically set on the spraying production line by the plug rod 3 and the positioning seat 4.

[0034] The implementation principle of the automatic feeding system for the production of spray-coated and baked glass containers in the embodiment of the present application is as follows: first, the positions of the two limit plates 2 on the conveyor line 1 are adjusted according to the size specifications of the glass container, and then the glass container is placed between the two limit plates 2 so that the bottle mouth of the glass container faces the annular transmission line 6. Then, a plurality of positioning seats 4 with plug-in rods 3 are placed on the conveyor belt 5 so that the limit blocks 17 on the positioning seats 4 are plugged into the limit grooves 16 on the conveyor belt 5. Then, the conveyor belt 5, the conveyor line 1 and the annular transmission line 6 are started. When the conveyor belt 5 transfers the positioning seat 4 to the side close to the annular transmission line 6 and the positioning seat 4 extends out of the conveyor belt 5, the annular transmission line 6 drives the claw 9 to rise. During the process of the claw 9 rising, the two ends of the positioning seat 4 are respectively inserted into the two claws 9. As the claw 9 continues to rise, the positioning seat 4 drives the plug-in rod 3 to move above the conveyor line 1. Driven by the distance sensor 10 and the visual sensor 11, the plug rod 3 is quickly aligned with the mouth of the glass container, ensuring that the mouth of the glass container can be smoothly sleeved on the plug rod 3 under the drive of the conveyor line 1. When the in-place switch 13 detects the mouth of the glass container, the in-place switch 13 can trigger the expansion and contraction member 12 to start, so that the expansion and contraction member 12 expands, so that the glass container is stably mounted on the plug rod 3. Finally, as the annular transmission line 6 drives the positioning seat 4, the plug-in rod 3 and the glass container to be lifted through the claw 9, when the image collector 15 detects that the claw 9 drives the positioning seat 4 to move above the annular transmission line 6, the image collector 15 drives the manipulator 14 to start, so that the manipulator 14 clamps the plug-in rod 3 with the glass container and moves it out from the opening of the claw 9. At this time, the plug-in rod 3 and the glass container are in a vertical state, and the manipulator 14 can stably place the positioning seat 4 on the spraying production line, so that under the action of the fixing parts, the glass container can be stably and vertically erected on the spraying production line by the plug-in rod 3 and the positioning seat 4, thereby completing the automatic loading of the glass container.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
