Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to an anti-dumping cosmetic glass bottle conveying device. Background Art

[0002] Cosmetics are usually stored in containers made of plastic, glass, metal and other materials. Glass bottles are one of the most common cosmetic containers. In the production process of cosmetic glass bottles, conveying the glass bottles is a key link in the entire production process. From the molding and production of glass bottles to the subsequent processing steps such as cleaning, labeling, and filling, conveying equipment is required to accurately transport the glass bottles to each workstation to ensure the continuity and efficiency of production.

[0003] In the prior art, conveyor belts are usually used to transport and transfer cosmetic glass bottles. Among them, a bottle-clamping transition conveyor belt is a common device used for conveying glass bottle containers. The glass bottle container is placed between two opposing conveyor belts, and the two conveyor belts are used to flexibly tighten the bottle body. As the two conveyor belts run synchronously, the glass bottle can be conveyed. This device can avoid blocking the bottom of the glass bottle, thereby facilitating coding at the bottom of the bottle.

[0004] However, the above-mentioned bottle clamping and transferring machines usually have a single function and only have the function of conveying glass bottles. They are unable to assist in completing key processes such as bottle cleaning and appearance inspection, and thus cannot meet actual production needs. Summary of the Invention

Sliding holes are evenly distributed on the top of the circular shell, and each sliding hole is connected to the piston hole one by one. Connecting holes are provided on the inner wall of the rotating section and connected to each piston hole. A piston body is adapted to be installed in each piston hole, and a guide rod is fixed on the top of each piston body. Each guide rod passes through the corresponding sliding hole and extends to the top of the circular shell. The top of each guide rod is fixed with a vertically upward extending push rod through a connecting plate, and the top of the push rod has a rubber head.

[0012] Preferably, a convex ring is fixed on the inner wall of each piston hole and located below the communicating hole, and a spring is sleeved on the outside of each guide rod, with the top end of the spring fixed to the bottom of the convex ring and the bottom end fixed to the top of the piston body.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] A concave section is formed on the running track of the first conveyor belt, a guide plate is arranged in the concave section, and a plurality of rubber ribs are arranged on the side of the guide plate. When the bottle body is transported to the concave section, it is squeezed and contacted with the rubber ribs and rotates. The adjustment component drives the bottle body to rise and fall, and the rubber ribs are used to scrape off dirt around the bottle body. The guide plate, the first conveyor belt, and the mounting plate form a dirt suction chamber, which is connected to an industrial vacuum cleaner through a dirt suction pipe for suction, and can discharge dirt to achieve bottle cleaning. This solves the problem that the conveying device in the traditional technology cannot coordinate to complete bottle cleaning. By combining the cleaning sponge and the industrial camera, the appearance inspection of the entire outer surface of the bottle and the bottom of the bottle can be realized. Before the appearance inspection, the bottom and the bottle body can be pre-cleaned to improve the accuracy of the inspection.

[0019] When the suction cup sucks the bottom of the bottle under negative pressure, due to the negative pressure environment in the rotating section, the piston body can be drawn upward under the action of the connecting hole, and the support rods are pushed upward synchronously under the connection action of the guide rod and the connecting plate. Finally, each support rod fits with the bottom of the bottle. The support rods evenly distributed around the suction cup fit with the bottom of the bottle, providing effective auxiliary support, which can prevent the bottle from tilting sideways during the lifting process and ensure the stability of bottle transportation.

[0020] By setting a spring, the initial negative pressure can be resisted. After the suction cup completely absorbs the bottom of the bottle, negative pressure continues to be generated. The pressure is enough to overcome the elastic force of the spring, causing the spring to compress and accumulate force, thereby causing the push rod to move up and collide with the bottom of the bottle, thereby avoiding the push rod moving up too quickly and colliding with the bottom of the bottle in advance, causing the suction cup and the bottom of the bottle to not be fully fitted and resulting in the inability to absorb the bottom of the bottle.

[0025] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Example

[0028] See also Figures 1-12 The present invention provides an anti-dumping cosmetic glass bottle conveying device, comprising a platform 1 and a pair of machine cover shells 3. The two machine cover shells 3 are arranged above the platform 1 through an adjustment mechanism 2. The adjustment mechanism 2 is used to drive the two machine cover shells 3 to move closer to or away from each other. A first belt conveyor mechanism 4 is provided in one machine cover shell 3, and a second belt conveyor mechanism 5 is provided in the other machine cover shell 3. A driving mechanism 8 is provided on one side of the platform 1. The driving mechanism 8 is used to drive the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5 to operate simultaneously. Among them, Figure 3 and Figure 4 As shown, the first belt conveyor mechanism 4 includes a first conveyor belt 42, a pair of first guide rollers 41 and four reversing rollers 44. The first guide rollers 41 and the reversing rollers 44 are respectively rotatably mounted in the housing 3. The first conveyor belt 42 is sleeved on the two first guide rollers 41 and passes around the corresponding reversing rollers 44 in sequence. The first conveyor belt 42 is located between the four reversing rollers 44 to form a concave section 43. The second belt conveyor mechanism 5 includes a second conveyor belt 52 and a pair of second guide rollers 51 . The two second guide rollers 51 are rotatably mounted in the machine housing 3 , and the second conveyor belt 52 is sleeved on the two second guide rollers 51 .

[0029] A bottle conveying channel is formed between the first conveyor belt 42 and the second conveyor belt 52. The driving mechanism 8 can drive the first guide roller 41 and the second guide roller 51 on one side to rotate simultaneously, thereby pulling the first conveyor belt 42 and the second conveyor belt 52 to run simultaneously, and placing the cosmetic glass bottle between the first conveyor belt 42 and the second conveyor belt 52 from the upstream side. The bottle body is squeezed by the first conveyor belt 42 and the second conveyor belt 52, and the glass bottle is clamped. The running first conveyor belt 42 and the second conveyor belt 52 can convey the glass bottle to the downstream, and during the conveying process, the glass bottle is prevented from falling due to the clamping effect on the glass bottle.

[0030] It is worth noting that a cleaning sponge block (not shown in the figure) is provided above the stand 1 and upstream of the concave section 43 in the present application. The cleaning sponge block is located below the bottle conveying channel. When the bottles are conveyed, the cleaning sponge block contacts the bottom of the bottles to clean the bottom of the bottles. The industrial inspection camera is arranged below the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5 and between the concave section 43 and the cleaning sponge block, so as to photograph the bottom of the bottles passing by for appearance inspection.

[0031] See also Figure 5 and Figure 6 , mounting plates 93 are fixed at the upper and lower parts of the housing shell 3 on one side. The positions of the two mounting plates 93 correspond to the positions of the inner concave section 43. A guide plate 9 is fixed between the two mounting plates 93. A plurality of rubber ribs 91 are vertically spaced apart on the side of the guide plate 9 close to the second belt conveyor mechanism 5. Each rubber rib 91 extends along the length direction of the platform 1. The end surface of each rubber rib 91 close to the second belt conveyor mechanism 5 is kept flush with the conveying surface of the first conveyor belt 42. When the bottle body is conveyed to the concave section 43, the bottle body is squeezed and contacted with the rubber strip 91. Since the guide plate 9 is fixed, the bottle body rotates along the surface of the rubber strip 91 under the friction driving action of the second conveyor belt 52 on the other side, and is conveyed downstream in a rolling manner. Among them, an adjustment component 6 is provided on the platform 1 below the two machine cover shells 3 and corresponding to the position of the concave section 43. Through the operation of the adjustment component 6, the bottle body is driven to rise and then fall during the downstream transportation process. By arranging the industrial inspection camera between the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5 and on the downstream side of the concave section 43, the rolling bottle body is photographed and inspected. Since the bottle body rotates, the entire circumference of the bottle body can be photographed and inspected.

[0032] In addition, before inspecting the outer appearance of the bottle body, the bottle body is moved up and down by adjusting the assembly 6, and the bottle body rotates on its own. The rubber ribs 91 in squeeze contact with the bottle body can be used to scrape off dirt on the entire circumferential side surface of the bottle body, thereby cleaning the outer wall of the bottle body and reducing the impact of dirt on the inspection accuracy.

[0033] Among them, multiple rubber ribs 91 are arranged from top to bottom, and the cleaning areas of multiple rubber ribs 91 complement each other in the vertical direction. The outer wall of the entire bottle body can be cleaned without lifting the bottle body a large distance, thereby avoiding the bottle body from being separated from between the rubber ribs 91 and the second conveyor belt 52 due to lifting a large distance.

[0034] In addition, the first conveyor belt 42, the second conveyor belt 52 and the rubber strips 91 are made of elastic materials and can adaptively deform to maintain clamping when the bottles are transported or lifted. Example

[0035] See also Figure 3 、 Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that: A dirt suction chamber 94 is formed between the guide plate 9, the first conveyor belt 42, and the two mounting plates 93. An elongated opening 92 communicating with the dirt suction chamber 94 is provided on the guide plate 9 between two adjacent rubber ribs 91. A dirt suction pipe 95 communicating with the dirt suction chamber 94 is connected to the upper mounting plate 93. The dirt suction pipe 95 extends through the upper portion of the housing 3 and is connected to an industrial vacuum cleaner (not shown). The industrial vacuum cleaner generates a negative pressure suction effect, forming a suction airflow that passes through the elongated opening 92, the suction cavity 94 and the mounting plate 93 in sequence, which can scrape the bottle body and suck out the dirt accumulated on the rubber ribs 91, thereby preventing excessive accumulation of dirt on the rubber ribs 91 and causing secondary contamination to the bottle body.

[0036] Among them, the elongated opening 92 extends along the length direction of the rubber rib 91, ensuring that the suction and decontamination range is sufficient to cover the elongated opening 92, thereby improving the decontamination effect on the rubber rib 91. In addition, the mounting plate 93 and the guide plate 9 serve as accessories for installing the rubber rib 91 and as a barrier to form the suction chamber 94. The structural layout of the first conveyor belt 42 at the concave section 43 allows the first conveyor belt 42 to serve as a barrier on the other side of the suction chamber 94, killing two birds with one stone. Example

[0037] See also Figure 7-Figure 9 The difference between this embodiment and embodiment 2 is that: The adjustment assembly 6 includes a power guide rail 61, a cylinder 62 and a suction device 7. The power guide rail 61 is installed on the stand 1 and extends along the conveying direction. The cylinder 62 is vertically fixed to the top of the movable seat 611 on the power guide rail 61. The telescopic end of the cylinder 62 is fixedly installed with a mounting seat 63. The suction device 7 is arranged above the mounting seat 63 and is used to suck the bottom of the bottle with negative pressure.

[0038] Among them, the holding device 7 includes a suction cup 71 and an air guide tube 72. The air guide tube 72 includes a rotating section 721, an L-shaped section 722 and a flexible section 723. The L-shaped section 722 is fixed on the mounting seat 63. The rotating section 721 is rotatably mounted on the vertical end of the L-shaped section 722 through a connecting sleeve 724. The suction cup 71 is mounted on the top of the rotating section 721. The flexible section 723 is connected to the horizontal end of the L-shaped section 722 and is connected to the air distribution system (not shown in the figure).

[0039] When the bottle reaches the concave section 43, the cylinder 62 extends to push the mounting seat 63 and the suction device 7 upward until the suction cup 71 contacts the bottom of the bottle. The air distribution system then draws negative pressure to hold the bottle in place. At the same time, the power guide rail 61 drives the movable seat 611 to move downstream, thereby driving the cylinder 62, the cylinder 62, and the suction device 7 to move downstream as a whole, ensuring synchronization with the downstream conveyance of the bottle. The cylinder 62 continues to extend to push the bottle body upward, and the cylinder 62 retracts to drive the bottle body downward, thereby providing drive for the lifting and lowering adjustment of the bottle body at the concave section 43.

[0040] In addition, since the rotating section 721 is rotatably connected to the L-shaped section 722 , the rotating section 721 and the suction cup 71 are capable of rotating to accommodate the self-rotation of the bottle body at the concave section 43 .

[0041] Among them, the rotating section 721 and the L-shaped section 722 are metal tubes to ensure effective supporting strength. The flexible section 723 is made of a rubber hose, which has the ability to bend and deform. At the same time, a certain length is reserved for the flexible section 723 to adapt to the position changes caused by the power guide rail 61 and the cylinder 62 during operation. Example

[0042] See also Figure 9 The difference between this embodiment and embodiment 3 is that: A circular shell 73 is fixedly mounted on the outside of the rotating section 721. Piston holes 731 are arranged in a circular array around the rotating section 721 in the circular shell 73. Sliding holes 732 are evenly distributed on the top of the circular shell 73. Each sliding hole 732 is connected to a piston hole 731 in a one-to-one correspondence. A connecting hole 733 is provided on the inner wall of the rotating section 721 to communicate with each piston hole 731. A piston body 74 is adapted to be installed in each piston hole 731. A guide rod 75 is fixed to the top of each piston body 74. Each guide rod 75 passes through the corresponding sliding hole 732 and extends to the top of the round shell 73. The top of each guide rod 75 is fixed with a vertically upward extending support rod 76 through a connecting plate.

[0043] When the suction cup 71 sucks the bottom of the bottle under negative pressure, due to the negative pressure environment in the rotating section 721, the piston body 74 can be pulled upward under the connection of the connecting hole 733, and the push rod 76 is pushed upward synchronously under the connection of the guide rod 75 and the connecting plate, and finally each push rod 76 is in contact with the bottom of the bottle.

[0044] Since the suction cup 71 is in flexible contact with the bottom of the bottle, the support rods 76 evenly distributed around the suction cup 71 fit with the bottom of the bottle, providing effective auxiliary support, which can prevent the bottle from tilting during the lifting process and ensure the stability of bottle transportation.

[0045] The top of the supporting rod 76 is provided with a rubber head 761 . The rubber head 761 is made of a soft material and plays a protective role when in contact with the bottom of the bottle.

[0046] In addition, a convex ring 78 is fixed on the inner wall of each piston hole 731 and below the connecting hole 733, and a spring 77 is sleeved on the outside of each guide rod 75. The top end of the spring 77 is fixed to the bottom of the convex ring 78, and the bottom end is fixed to the top of the piston body 74.

[0047] In the initial stage when the suction cup 71 is sucked onto the bottom of the bottle, the negative pressure generated in the rotating section 721 is insufficient to overcome the elastic force of the spring 77, causing the suction piston 74 to move upward and drive the push rod 76 to contact the bottom of the bottle. After the suction cup 71 has completely sucked onto the bottom of the bottle, the negative pressure continues to be generated, which is sufficient to overcome the elastic force of the spring 77, causing the spring 77 to compress and accumulate force, thereby moving the push rod 76 upward to contact the bottom of the bottle, thereby preventing the push rod 76 from moving up too quickly and colliding with the bottom of the bottle in advance, causing the suction cup 71 to not completely contact the bottom of the bottle and thus failing to suck the bottom of the bottle. On the other hand, after the negative pressure holding is cancelled, the elastic force of the spring 77 is used to drive the piston body 74 to move downward and reset. Example

[0048] See also Figure 2 、 Figure 10 and Figure 11 The difference between this embodiment and embodiment 4 is that: The adjustment mechanism 2 includes a bidirectional threaded rod 22 and a nut seat 23. Two first brackets 21 are symmetrically fixed above the stand 1. The bidirectional threaded rod 22 is rotatably mounted on the two first brackets 21. A rocker 231 is mounted on one end of the bidirectional threaded rod 22. Nut seats 23 are fixed to the bottom surfaces of the two machine housings 3. The two nut seats 23 are threadedly matched and fit on both sides of the bidirectional threaded rod 22. Two arch frames 24 are fixed above the stand 1, and rails 25 are fixed on the top of the two arch frames 24, wherein the cross-section of the rails 25 is T-shaped, and sliding seats 26 are fixed at the bottom surface of the hood shell 3 corresponding to the positions of the two rails 25. The sliding seats 26 are slidably installed on the corresponding rails 25 respectively, and the cooperation between the rails 25 and the sliding seats 26 plays a guiding and limiting role for the two hood shells 3.

[0049] By shaking the rocker 231, the bidirectional threaded rod 22 is driven to rotate forward. Under the guiding and limiting action of the track 25 and the sliding seat 26 on the machine cover shell 3, the rotating bidirectional threaded rod 22 threadably drives the two nut seats 23 and drives the two machine cover shells 3 to approach each other. By shaking the rocker 231, the bidirectional threaded rod 22 is driven to reverse. Similarly, the two machine cover shells 3 can be driven away from each other, thereby realizing the spacing adjustment of the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5 to adapt to bottles of different diameters, with high versatility.

[0050] The driving mechanism 8 includes a driving motor 82, a shaft 83 and a worm 84. A motor base 81 is fixed to the frame 1, the driving motor 82 is fixed to the motor base 81, and the shaft 83 is fixed to the output shaft of the driving motor 82. Two frames 841 are fixed to the bottom surfaces of the two housings 3, and a worm 84 is rotatably mounted on the two frames 841 on the same side. The two worm gears 84 are respectively mounted on both sides of the shaft 83 through the holes 842 thereon. The first guide roller 41 and the second guide roller 51 on one side extend through to the bottom of the machine cover shell 3 and are fixedly mounted with a worm gear 85. The two worm gears 85 are respectively engaged with the corresponding worm gears 84.

[0051] By driving the motor 82, its output shaft drives the shaft 83 to rotate, and the rotating shaft 83 drives the two worms 84 to rotate. The two worms 84 are synchronously engaged to drive the worm wheel 85 on the same side to rotate, and then synchronously drive the first guide roller 41 and the second guide roller 51 to rotate, thereby realizing the simultaneous operation of the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5.

[0052] Among them, Figure 12 As shown, both worms 84 can slide along the shaft 83 , and both channels 842 have key slots 843 . A strip key 831 is fixed on the outer wall of the shaft 83 , and the strip key 831 is correspondingly limited and mounted in the two key slots 843 .

[0053] The two worm gears 84 can slide on the shaft 83 to adapt to the spacing adjustment of the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5. At the same time, through the limiting cooperation between the strip key body 831 and the channel 842, it is ensured that the worm gear 84 can only slide and adjust along the shaft 83 and cannot rotate on its own, thereby ensuring the effectiveness of the transmission.

[0054] By setting the above-mentioned driving mechanism, the first belt conveyor mechanism 4 and the second belt conveyor mechanism 5 can share the same driving source while being able to adjust the distance between them, thereby reducing the driving cost.

[0055] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field.
