Description

Technical Field

[0001] The present invention relates to the technical field of bottling production equipment, and in particular to a low-friction and high-efficiency conveying slide device for bottle caps. Background Art

[0002] Currently, most companies still use traditional conveyor belts for bottle cap delivery in bottling production lines. This method typically uses a motor-driven belt or chain to move the caps, which are arranged on a vibrating plate or robotic arm before being transported to the capping station by a conveyor belt. However, this method has many drawbacks:

[0003] High energy consumption: The conveyor belt system needs to run continuously and consumes electricity even at low speed or no-load state. In addition, due to the large friction resistance, the power loss is obvious, and long-term operation leads to energy waste.

[0004] Complex structure: The conveyor belt system usually includes multiple components such as the drive motor, tensioning mechanism, guide device, support frame, etc. The equipment is bulky, and the installation and debugging process is cumbersome, which increases the difficulty of production line layout.

[0005] Inconvenient maintenance: The conveyor belt or chain is easy to wear and needs to be replaced regularly. At the same time, transmission components such as bearings and gears may suffer from poor lubrication or mechanical fatigue after long-term operation, resulting in increased failure rate and high maintenance costs.

[0006] In addition, on the aseptic production line of bottle caps, traditional conveyor belt transportation faces more severe challenges:

[0007] Hygiene hazards: Dust and microorganisms are easily accumulated in the gaps and joints of the conveyor belt, which are difficult to clean and disinfect thoroughly. They may contaminate the bottle caps and affect the sterility of the product.

[0008] High cleanliness requirements: Sterile environments usually require avoiding open transportation, but traditional conveyor belts are difficult to achieve completely closed operation, which increases the difficulty of clean room environment control.

[0009] Therefore, the existing bottle cap conveying method is difficult to meet the stringent requirements of modern food, medicine and other industries for high efficiency, energy saving and aseptic production, and a more optimized conveying solution is urgently needed. Summary of the Invention

[0046] Example 1:

[0047] Please refer to Figure 1-8 As shown, this embodiment provides a low-friction and high-efficiency conveying slide device for bottle caps, comprising a frame assembly 10, and a rolling assembly 20 and an air source assembly 30 mounted on the frame assembly;

[0048] The frame assembly 10 includes a frame base 11 and a frame top cover 12; the frame base 11 serves as a bottom bearing component and has corresponding load-bearing and supporting capabilities; the frame top cover 12 is detachably covered on the top of the frame base 11; a conveying channel 13 is formed between the frame base 11 and the frame top cover 12, and an inlet flange 14 and an outlet flange 15 are respectively provided at both ends of the conveying channel 13, the inlet flange 14 is used to connect to the bottle cap supply device, and the outlet flange 15 is used to connect to the bottle cap receiving device.

[0049] An inlet connecting channel 141 is formed between the inlet flange 14 and the frame base 11, one end of the inlet connecting channel 141 forms a bottle cap inlet 1411, and the other end is connected to the conveying trough 13; the top of the inlet flange 14 is connected to a main gas source pipeline 16, and a main gas source channel 161 is formed in the main gas source pipeline 16, one end of the main gas source channel 161 forms a gas source connection port 162, and the other end is connected to the inlet connecting channel 141.

[0050] An outlet connecting channel 151 is formed between the outlet flange 15 and the frame base 11 . One end of the outlet connecting channel 151 forms a bottle cap outlet 1511 , and the other end is communicated with the conveying channel 13 .

[0051] The rolling assembly 20 is disposed at the bottom of the conveying channel 13 and is used for rolling contact with the bottle caps;

[0052] The gas source assembly 30 includes a gas supply pipe and a gas supply device (not shown), one end of the gas supply pipe is connected to the gas source connection port 162, and the other end is connected to the gas supply device;

[0053] Based on the above structure, during use, the bottle caps are oriented and arranged by a bottle cap supply device such as a vibration plate or a manipulator and then enter the bottle cap inlet 1411 of the inlet flange 14; the gas is input into the conveying channel 13 through the main gas source channel 161 by the air supply device, and the air supply device generates a stable and controllable cap-transporting airflow in the conveying channel 13, and provides power through the cap-transporting airflow to make the bottle caps float or roll forward in the air duct, and transport the bottle caps from the bottle cap inlet 1411 to the bottle cap outlet 1511 to avoid mechanical friction. The bottle cap low-friction and high-efficiency conveying slide device of this embodiment only needs a fan to provide airflow during operation, and does not require continuous mechanical transmission, which reduces energy consumption by 30% to 50%. In addition, there are no complex transmission parts, which reduces mechanical wear and has low maintenance costs. The conveying channel 13 formed between the frame base 11 and the frame top cover 12 is used to convey the bottle caps, which is conducive to forming a closed conveying environment, can avoid dust and microbial contamination, and meets the aseptic standards such as GMP and FDA. It can effectively solve the problems of high energy consumption, high pollution, and difficult maintenance of traditional conveyor belts. Through a simple mechanical structure, wind power is efficiently utilized, the friction loss of the bottle caps during transportation is reduced, and the purpose of high-speed and low-loss conveying of the bottle caps is achieved.

[0054] In this embodiment, the conveying channel 13 is arranged horizontally, and the main gas source pipeline 16 is arranged obliquely; that is, an acute angle is formed between the main gas source channel 161 and the conveying channel 13, and the acute angle is the angle A, preferably, 15°≤A≤30°. The main gas source channel 161 has a tapered section 1611, and a throat 1612 is formed at the end of the tapered section 1611. The cross-section of the tapered section 1611 gradually decreases from the gas source connection port 162 to the throat 1612. The throat 1612 is arranged at the connection between the main gas source channel 161 and the inlet connection channel 141. Specifically, an inclined plate 163 is fixed at the connection between the main gas source pipeline 16 and the inlet flange 14. The inclined plate 163 is arranged in the main gas source channel 161, and an angle B is formed between the inclined plate 163 and the conveying channel 13, B<A; thereby forming a tapered section 1611 in the main gas source channel 161.

[0055] During use, the air source assembly 30 supplies compressed air from the inclined main air source pipe 16. The gas will undergo a process of compression to diffusion after passing through the tapered section 1611 and the throat 1612, and a Venturi tube structure is formed at the connection between the main air source channel 161 and the inlet connecting channel 141. The back pressure area formed by the inlet connecting channel 141 in the opposite direction of the airflow can suck the bottle caps into the conveying path to complete contactless feeding, avoiding external contamination, and is particularly suitable for aseptic production lines.

[0056] Furthermore, a compensation air source pipe 17 is provided on the rack top cover 12, and a compensation air flow channel 171 is formed in the compensation air source pipe 17. One end of the compensation air flow channel 171 is connected to the conveying trough 13, and the other end is used to communicate with the air source component 30; an angle C is formed between the compensation air flow channel 171 and the conveying trough 13, preferably, 15°≤C≤30°.

[0057] The main gas source pipeline 16 has a diversion pipeline 164, which is arranged near the gas source connection port 162. A diversion channel is formed in the diversion pipeline 164. One end of the diversion channel is connected to the main gas source channel 161, and the other end is connected to the compensation air flow channel 171 through the connecting pipe 18.

[0058] The compressed air supplied by the air source assembly 30 enters the main air source pipeline 16 and is diverted through the diversion pipeline 164. The diverted gas enters the middle section of the conveying channel 13 through the connecting pipe 18 and the compensation air flow channel 171 to compensate for the power loss of the main air flow in the process of conveying the bottle caps. The diverted gas forms a second Venturi tube structure at the connection between the compensation air flow channel 171 and the conveying channel 13, that is, the middle section of the conveying channel 13. The generated back pressure area will accelerate the bottle caps again in the conveying path.

[0059] In a longer conveying path, multiple compensation air source pipes 17 can also be set. Several compensation air source pipes 17 are arrayed at specific intervals in the length direction of the rack top cover 12 to achieve multi-stage power compensation and speed increase of the bottle caps in the conveying trough 13.

[0060] The conveying channel 13 of this embodiment may also have a climbing end or a reversing section. A climbing air source pipe or a guiding air source pipe may be set on the climbing end and the reversing section. The climbing air source pipe or the guiding air source pipe blows toward the conveying pipe at a specific speed and angle. The climbing air source pipe strengthens the airflow to assist the bottle caps in climbing, and the guiding air source pipe provides a guiding airflow to assist the bottle caps in turning, etc. In this way, the conveying path can be flexibly adjusted to achieve flexible production.

[0061] An outlet air flow channel 152 may also be provided in the outlet flange 15 . By connecting the outlet air flow channel 152 to the air source assembly 30 , the bottle caps at the outlet connecting channel 151 may be more smoothly delivered from the bottle cap outlet 1511 .

[0062] The main air source pipeline 16, the compensation air source pipeline 17, the climbing air source pipeline, the guide air source pipeline, and the outlet air flow channel 152 can all share an air supply device, or each can be equipped with an independent air supply device for independent control. The air supply device can use a variable frequency fan connected to a flow sensor to adjust the wind speed in real time to ensure the control of the bottle caps during the transportation process.

[0063] As an extension, the air supply pipe can be equipped with HEPA filtration or sterile positive pressure air duct, and the sterile positive pressure air duct can integrate air filtration and UV sterilization modules to meet the sterility requirements of medicine and food grade.

[0064] In this embodiment, the conveying trough 13 is further provided with a trough base 131 and a quick-release sealing plate 132. The trough base 131 is fixed to the frame base 11, and the quick-release sealing plate 132 is connected to the frame top cover 12. The provision of the trough base 131 and the quick-release sealing plate 132 can improve the airtightness of the conveying trough 13, reduce airflow loss, and prevent contamination inside the conveying trough 13.

[0065] Specifically, the channel base 131 has side panels and a bottom plate, and a connecting groove 1311 is formed on the bottom surface of the bottom plate; a connecting hole 111 is provided on the rack base 11, and fasteners 1312 are provided in the connecting groove 1311 and the connecting hole 111, and the channel base 131 is fixed to the rack base 11 by the fasteners 1312.

[0066] A limiting groove 1321 is formed within the quick-release sealing plate 132, allowing only one bottle cap to pass through. A low-friction coating can also be provided within the limiting groove 1321 to reduce wear on the bottle cap. Furthermore, a quick-release screw 1322 and a quick-release nut 1323 are provided at the top of the quick-release sealing plate 132; a connecting groove 121 is provided at a corresponding position on the frame top cover 12; the quick-release screw 1322 passes through the connecting groove 121 and connects to the quick-release nut 1323.

[0067] Furthermore, a first installation slot 1313 and a second installation slot 1314 are respectively defined on two opposite side plates of the channel base 131 .

[0068] The rolling assembly 20 includes a plurality of roller array modules 21, each of which includes a first connecting rod 211, a second connecting rod 212, and a plurality of roller units 213. One end of the roller unit 213 is pivotally connected to the first connecting rod 211, and the other end is pivotally connected to the second connecting rod 212. The plurality of roller units 213 are linearly arrayed between the first connecting rod 211 and the second connecting rod 212.

[0069] The first connecting rod 211 is inserted into the first installation slot 1313 , and the second connecting rod 212 is inserted into the second installation slot 1314 .

[0070] Through the rolling assembly 20, the low-friction and high-efficiency conveying slide device of the bottle cap can combine the high efficiency of airflow conveying and the stability of mechanical guidance, and is particularly suitable for high-precision, high-cleanliness, and high-speed production environments; this embodiment divides the traditional continuous integrated roller row into multiple independent roller row modules 21, and each section of the roller row module 21 can be disassembled, replaced or repaired separately, reducing maintenance time and maintenance costs. Different bottle cap specifications can be matched with different independent roller row modules 21, thereby improving the flexibility of the production line; the modular rolling assembly 20 improves overall flexibility, energy saving and controllability.

[0071] A gas diffusion area is formed at the top of the limiting groove 1321. When the continuous bottle caps enter the conveying pipe, the cap-carrying airflow contacts the bottle caps so that the cap-carrying airflow is diverted again. One part is used to displace the bottle caps in the conveying direction, and the other part flows to the top of the bottle caps. The flow rate of the gas above the bottle caps will be faster than that below the bottle caps. The negative pressure formed above the quick-release cap channel will generate an upward lift on the bottle caps. Secondly, even if the bottle caps are in rolling contact with the roller row module 21, the roller unit 213 applies centrifugal force to the bottle caps in contact with it during the rotation process, and the centrifugal force drives the bottle caps to be thrown out along the tangent direction of the contact point. Under the combined action of the lift and centrifugal force, the bottle caps are suspended in the limiting groove 1321, reducing the contact area between the bottle caps and the roller row module 21, thereby reducing the loss of the bottle caps during the conveying process.

[0072] The quick-release sealing plate 132 can be quickly disassembled and assembled according to different cap types through the quick-release screw 1322 and the quick-release nut 1323. The cross-sectional size of the cap limiting groove 1321 allows the low-friction and high-efficiency conveying slide device of the bottle cap to be quickly matched with the bottle cap production line to achieve rapid changeover.

[0073] Preferably, the top surface of the rack base 11 of this embodiment is provided with a lower step surface, and the bottom surface of the rack top cover 12 is provided with an upper step surface.

[0074] The rack top cover 12 is hinged to one side of the rack base 11 by a hinge, so that the rack top cover 12 can be flipped relative to the rack base 11. By flipping the rack top cover 12, the upper step surface and the lower step surface are engaged to close the conveying chute 13, or the upper step surface and the lower step surface are separated to open the conveying chute 13.

[0075] A jam detection assembly is provided between the rack base 11 and the rack top cover 12. The jam detection assembly includes a sensing block 191 and a proximity switch 192. The sensing block 191 is fixed to the upper step surface, and the proximity switch 192 is fixed to the lower step surface.

[0076] It also includes a main control system, which includes a jam detection module and a human-computer interaction module. The jam detection module is signal-connected to the jam detection component, and the jam detection module is electrically connected to the air supply device. When the jam detection module receives a disconnection signal between the sensing block 191 and the proximity switch 192, the jam detection module controls the air supply device to stop supplying air, and outputs a jam warning message through the human-computer interaction module.

[0077] By hingedly connecting the rack cover 12 to the rack base 11, the rack cover 12 relies on its own weight to tightly fit the stepped surface of its lower portion against the stepped surface of the rack base 11 during operation. During operation, when different types of bottle caps or deformed bottle caps are sucked into the low-friction, high-efficiency bottle cap conveying slide device, the lateral thrust of the gas will squeeze the bottle caps and cause them to become stuck in the limiting groove 1321, impairing gas diffusion. The accumulated gas will push the rack cover 12 upward. At the same time, if the proximity switch 192 fails to detect the sensor block 191, it will send a signal to the main control system to shut down the gas supply, thereby stopping the conveying system and initiating the troubleshooting procedure.

[0078] In other embodiments, a bottle cap conveying monitoring module is further included. A window 122 is provided on the surface of the frame top cover 12, and a light-transmitting plate material is used at the corresponding position of the quick-release sealing plate 132. By setting a sensor probe or an AI camera probe in the window 122, the bottle cap conveying status within the limiting groove 1321 is obtained in real time. The bottle cap conveying status may include information such as the conveying posture of the bottle cap and the spacing between the bottle caps. Based on the bottle cap conveying status, the air supply rate of the air source assembly 30 is adjusted to achieve dynamic control of the bottle cap conveying process.

[0079] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
