Description

Technical Field

[0001] This utility model relates to the field of bottle cap conveying technology, specifically a bottle cap single-row sorting and conveying device. Background Technology

[0002] Plastic bottle caps are sealing components made from polyolefin materials such as polyethylene (PE) or polypropylene (PP) through injection molding or compression molding processes. They are mainly used for packaging beverages, food, pharmaceuticals, and chemical products. The production process of plastic bottle caps involves material conveying using conveying equipment. The existing technology is authorized by publication number CN 218595417. U's patent discloses a sorting and conveying device for bottle cap production, including a fixed base plate. A conveyor belt mechanism is mounted on the top outer wall of the fixed base plate. Connecting side plates are mounted on both side walls of the conveyor belt mechanism, and guide components are mounted on the top outer walls of the connecting side plates. Support plates are mounted on both side walls of the fixed base plate. A sorting plate is fixedly mounted on one side wall of each support plate. A groove is formed in the sorting plate, and a top block is provided inside the groove. An oblique air hole is formed on the top block. An air inlet pipe is provided on the sorting plate, and the oblique air hole is connected to the air inlet pipe. Through-beam photoelectric sensors are mounted on both side walls of the sorting plate. Through the sorting plate, top block, oblique air hole, and through-beam photoelectric sensors, the conveying device can accurately remove bottle caps facing the wrong direction during transport, thereby improving efficiency. To improve subsequent production efficiency, when the device removes defective bottle caps during the conveying process, the entire bottle cap needs to be inserted into the groove to be selected. However, the groove is a circular structure with a small gap between itself and the bottle cap, and the device cannot ensure that every defective bottle cap is inserted into the groove. The screening rate of defective bottle caps needs to be improved. At the same time, the device uses air blowing to remove defective bottle caps. However, since both the defective bottle cap and the air blowing element are located in the groove, the bottle cap may be obstructed by the sliding limit between the bottle cap and the groove during the air blowing process, causing the bottle cap to tilt and fly out, which affects the unloading operation of defective bottle caps. Therefore, we propose a single-row sorting and conveying device for bottle caps. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a single-row sorting and conveying device for bottle caps. This device uses two-point comparison detection to detect unqualified plastic bottle caps during the single-row sorting and conveying process. The plastic bottle cap detection is performed on a flat surface, eliminating the need for insertion into grooves to detect unqualified products, thus improving the device's accuracy in screening unqualified plastic bottle caps. Simultaneously, the device uses a transmission element to horizontally squeeze and remove unqualified plastic bottle caps from the conveying equipment. The removal of unqualified plastic bottle caps is controllable and convenient, effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bottle cap single-row sorting and conveying device, including a conveyor, wherein limiting plates are provided at both the front and rear ends of the upper side of the conveyor, and a rejection mechanism is also included;

[0005] The rejection mechanism includes grooves, inclined slides, detection elements, rejection components, and a conveyor plate. The grooves are symmetrically opened laterally on the side of the limiting plate away from the longitudinal center of the conveyor. Inclined slides are slidably connected inside the grooves. Detection elements and rejection components are respectively provided on the outside of the conveyor. The rejection components are installed in conjunction with the inclined slides. A conveyor plate is provided at the upper rear end of the conveyor. This device uses two-point comparison detection to detect unqualified plastic bottle caps during the single-row sorting and conveying process. The plastic bottle cap detection is on a plane, eliminating the need for the plastic bottle caps to be inserted into the grooves to detect unqualified products, thus improving the accuracy of the device in screening unqualified plastic bottle caps. At the same time, the device uses horizontal extrusion through transmission elements to remove unqualified plastic bottle caps from the conveying equipment. The operation of rejecting unqualified plastic bottle caps is controllable and convenient.

[0006] Furthermore, it also includes a microcontroller, which is located outside the conveyor. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminal of the conveyor is electrically connected to the output terminal of the microcontroller, which facilitates the control of electrical components within the device.

[0007] Furthermore, the rejection mechanism also includes a synchronizing rod, which is respectively disposed between the upper sides of two longitudinally adjacent inclined slide plates, so that the two longitudinally adjacent inclined slide plates in the bottle cap single-row sorting conveyor can move laterally synchronously.

[0008] Furthermore, the detection element includes a connecting seat one, a laser sensor one, and a laser sensor two. The connecting seat one is located at the upper front end of the conveyor. The upper end of the connecting seat one is provided with a horizontally distributed laser sensor one and a laser sensor two. The laser sensor one is located to the right of the laser sensor two. Both the laser sensor one and the laser sensor two are bidirectionally electrically connected to the microcontroller. The plastic bottle caps in the single-row sorting conveyor are detected by comparing the thickness at two points.

[0009] Furthermore, the rejection assembly includes a second connecting seat, an electro-hydraulic push rod, a rejection seat, and guide rods. The second connecting seat is located at the upper right front end of the conveyor. The front side of the second connecting seat is equipped with an electro-hydraulic push rod, the input end of which is electrically connected to the output end of the microcontroller. The telescopic end of the electro-hydraulic push rod is equipped with a rejection seat, which is installed in conjunction with two inclined sliding plates on the front side. The front side of the rejection seat is equipped with two symmetrically distributed guide rods, the front ends of which are slidably connected to a circular hole on the front side of the second connecting seat, to reject unqualified plastic bottle caps in the single-row sorting conveyor.

[0010] Furthermore, the rejection mechanism also includes a connecting seat three, a telescopic column, and a spring. The connecting seat three is symmetrically arranged laterally on the front side of the limiting plate. The connecting seat three and the laterally adjacent inclined slide plate are provided with vertically symmetrically distributed telescopic columns and springs. The springs are all movably connected to the outer ends of the vertically adjacent telescopic columns, so that the two laterally adjacent inclined slide plates in the bottle cap single-row sorting conveyor can automatically close after they are separated from each other.

[0011] Furthermore, a connecting seat is provided on the right side of the conveyor, and an arc-shaped limiting seat is provided in the middle of the upper side of the connecting seat. A photoelectric sensor is provided between the front and rear ends of the upper side of the connecting seat. The photoelectric sensor is bidirectionally electrically connected to the microcontroller to detect and limit the plastic bottle cap at the far right of the bottle cap single-row sorting conveyor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This bottle cap single-row sorting and conveying device has the following advantages:

[0013] 1. When using the bottle cap single-row sorting and conveying equipment, the device uses the thickness difference between two points by the detection element and the conveyor to detect unqualified plastic bottle caps in the single-row sorting and conveying process. The plastic bottle caps are all on a plane during the detection process, so there is no need to insert the plastic bottle caps into the groove to detect unqualified products, thus improving the accuracy of the device in screening unqualified plastic bottle caps.

[0014] 2. When using a bottle cap single-row sorting conveyor, defective plastic bottle caps can be horizontally and longitudinally squeezed out of the conveyor by components such as rejection components, grooves and inclined slides, using inclined extrusion to avoid them.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This embodiment provides a technical solution: a bottle cap single-row sorting and conveying device, including a conveyor 1, with limiting plates 3 at both the front and rear ends of the upper side of the conveyor 1, and also includes a microcontroller 2, which is located outside the conveyor 1. The input end of the microcontroller 2 is electrically connected to an external power supply, and the input end of the conveyor 1 is electrically connected to the output end of the microcontroller 2.

[0020] When the device is used to sort and convey plastic bottle caps in a single row, the plastic bottle caps are guided by the connecting shell at the left end of the device through the external feeding equipment and enter the upper left chain plate of the conveyor 1 at a certain interval. Then, the microcontroller 2 starts the conveyor 1, and the internal motor causes the sprocket to drive the chain to move back and forth in a cycle. During the movement of the chain, the chain plate is pulled to carry the plastic bottle caps at its upper end horizontally from left to right. The longitudinal gap between the two limiting plates 3 is slightly larger than the maximum diameter of the plastic bottle cap. The two limiting plates 3 cooperate with each other to limit the longitudinal movement of the plastic bottle caps as they move from left to right with the chain plate of the conveyor 1. It also includes a rejection mechanism 4.

[0021] The rejection mechanism 4 includes a groove 41, an inclined slide plate 42, a detection element 44, a rejection assembly 45, and a chute 49. The grooves 41 are symmetrically opened laterally on the side of the limiting plate 3 away from the longitudinal center of the conveyor 1. The inclined slide plate 42 is slidably connected inside the grooves 41. The detection element 44 and the rejection assembly 45 are respectively provided on the outside of the conveyor 1. The rejection assembly 45 is installed in cooperation with the inclined slide plate 42. The chute 49 is provided at the upper rear side of the conveyor 1.

[0022] The detection element 44 includes a connecting base 441, a laser sensor 442, and a laser sensor 443. The connecting base 441 is located at the upper front end of the conveyor 1. The upper end of the connecting base 441 is equipped with horizontally distributed laser sensors 442 and 443, with laser sensor 442 located to the right of laser sensor 443. Both laser sensors 442 and 443 are bidirectionally electrically connected to the microcontroller 2. During the single-row, right-hand conveying of bottle caps, the microcontroller 2 activates laser sensors 442 and 443. Both laser sensors 442 and 443 emit light signals that illuminate the upper surface of the vertically downward conveyor chain plate and reflect back to their initial positions. Based on the propagation time and speed of the light signal, the vertical distance between the two sensors is measured, and the measurement result is transmitted to the microcontroller 2 as an electrical signal. The lateral distance between the laser emission points of the two sensors 443 is half the maximum diameter of the bottle cap. The closed surfaces of the two adjacent inclined slide plates 42 are longitudinally aligned. When the plastic bottle cap passes through the laser sensor 443, the distance measurement result of the laser sensor 443 changes. When the plastic bottle cap passes through the laser sensor 442, the distance measurement result of the laser sensor 442 changes. Then, the microcontroller 2 compares the distance measurement changes of the laser sensor 442 and the laser sensor 443. If the difference between the two is close to the thickness value of the plastic bottle cap, then the plastic bottle cap is a defective product with the bottom facing up. This device uses two-point comparison detection to detect defective plastic bottle caps in the single-row sorting and conveying process. The plastic bottle cap detection is on a plane, and there is no need to insert the plastic bottle cap into the groove to detect defective products, thus improving the accuracy of the device in screening defective plastic bottle caps.

[0023] The rejection assembly 45 includes a second connecting seat 451, an electro-hydraulic push rod 452, a rejection seat 453, and a guide rod 454. The second connecting seat 451 is located at the upper right end of the front side of the conveyor 1. The front side of the second connecting seat 451 is provided with an electro-hydraulic push rod 452. The input end of the electro-hydraulic push rod 452 is electrically connected to the output end of the microcontroller 2. The telescopic end of the electro-hydraulic push rod 452 is provided with a rejection seat 453. The rejection seat 453 is installed in conjunction with two inclined sliding plates 42 on the front side. The front side of the rejection seat 453 is provided with two guide rods 454 that are symmetrically distributed laterally. The front ends of the guide rods 454 are slidably connected to the circular hole 1 opened on the front side of the second connecting seat 451.

[0024] The microcontroller 2 activates the electro-hydraulic actuator 452, causing its telescopic end to move the rejection seat 453 longitudinally backward. During the longitudinal backward movement of the rejection seat 453, the guide rod 454 adaptively slides along the corresponding circular hole. The sliding connection between the two supports the radial pressure applied to the telescopic end of the electro-hydraulic actuator 452 by the rejection seat 453, thereby preventing damage to the telescopic end of the electro-hydraulic actuator 452 due to radial pressure. The diameter of the guide rod 454 is the same as the diameter of the circular hole. After the rejection seat 453 moves longitudinally backward to a certain position, the left and right edges of the rear end of the rejection seat 453 are aligned with the front end. The inclined surfaces of the corresponding inclined slide plate 42 on the side are pressed into contact, and the inclined surface of the front inclined slide plate 42 is pressed into the corresponding groove 41 to avoid position. The two adjacent inclined slide plates 42 in the lateral direction separate and open from each other. Then the rear groove of the rejection seat 453 contacts the outer arc surface of the plastic bottle cap placed in the opposite direction at this position. The contact pressure pushes the unqualified plastic bottle cap to move backward to the conveyor plate 49 for discharge. The diameter of the rear groove of the rejection seat 453 is larger than the maximum diameter of the plastic bottle cap, thereby ensuring that the plastic bottle cap can be in the rear groove of the rejection seat 453 during the longitudinal backward movement of the rejection seat 453.

[0025] An inclined plate is provided at the upper rear end of conveyor 1. Guided by the inclined plate, plastic bottle caps are moved longitudinally backward from the chain plate to the upper rear edge of conveyor 1 and enter the chute 49. When the rejecting seat 453 moves the defective plastic bottle caps to the chute 49, the left and right sides of the front of the rejecting seat 453 are still in a state of compression contact with the corresponding inclined sliding plates 42. Then, the microcontroller 2 controls the extension and retraction of the electro-hydraulic push rod 452 to drive the rejecting seat 453 to move longitudinally forward and reset. The compression and reset force of the spring 48 then causes the front... The inclined slide plate 42 on the side drives the inclined slide plate 42 on the rear side to reset along the corresponding groove 41 through the synchronous rod 43, thereby automatically sealing the opening and closing part of the limit plate 3. The microcontroller 2 controls the extension and reset stroke of the extension end of the electro-hydraulic push rod 452 based on its own timing unit and the moving speed of the extension end of the electro-hydraulic push rod 452 per unit time. The device removes unqualified plastic bottle caps from the conveying equipment by horizontal squeezing through the transmission element. The operation of removing unqualified plastic bottle caps is controllable and convenient.

[0026] The rejection mechanism 4 also includes a connecting seat 46, a telescopic column 47, and a spring 48. The connecting seat 46 is symmetrically arranged on the front side of the front limiting plate 3. The connecting seat 46 and the horizontally adjacent inclined slide plate 42 are both provided with vertically symmetrically distributed telescopic columns 47 and springs 48. The springs 48 are movably sleeved with the outer ends of the vertically adjacent telescopic columns 47. The inclined surface of the front inclined slide plate 42 is pressed into the corresponding groove 41 to avoid position. The telescopic end of the telescopic column 47 and the spring 48 retract. The retraction of the spring 48 enables the two horizontally adjacent inclined slide plates 42 to automatically close and contact for power storage. After the device has been used for a period of time, the connecting seat 46 and its connecting elements are completely removed and replaced. The connecting seat 46 is fixed to the corresponding limiting plate 3 with screws to avoid aging of the spring 48 on the right side of the connecting seat 46.

[0027] The rejection mechanism 4 also includes a synchronizing rod 43, which is respectively set between the upper sides of two longitudinally adjacent inclined slide plates 42. The front inclined slide plate 42 drives the longitudinally rear inclined slide plate 42 to move synchronously through the synchronizing rod 43.

[0028] A connecting seat 5 is provided on the right side of the conveyor 1. An arc-shaped limiting seat 6 is provided on the upper middle part of the connecting seat 5. A photoelectric sensor 7 is provided between the front and rear ends of the upper side of the connecting seat 5. The photoelectric sensor 7 is bidirectionally electrically connected to the microcontroller 2. When the plastic bottle cap moves to the connecting seat 5 with the chain plate of the conveyor 1, the arc-shaped limiting seat 6 limits the plastic bottle cap to the right at this position. At the same time, the microcontroller 2 activates the photoelectric sensor 7. The photoelectric sensor 7 is a through-beam type. When the plastic bottle cap passes through the through-beam gap of the photoelectric sensor 7, the electrical signal transmitted by the photoelectric sensor 7 to the microcontroller 2 changes. Then the microcontroller 2 shuts down the conveyor 1. When the plastic bottle cap in the arc-shaped limiting seat 6 is removed by the external device on the right side of the device, the microcontroller 2 starts the conveyor 1 again to continue conveying the plastic bottle cap in the arc-shaped limiting seat 6 through the same principle.

[0029] The working principle of the bottle cap single-row sorting and conveying device provided by this utility model is as follows: When the device is used to sort and convey plastic bottle caps in a single row, the plastic bottle caps are guided by the external feeding device through the connecting shell at the left end of the device itself and enter the upper left chain plate of the conveyor 1 at a certain interval. Then, the microcontroller 2 starts the conveyor 1, and the internal motor causes the sprocket to drive the chain to move back and forth in a cycle. During the movement of the chain, the chain plate is pulled to move the plastic bottle caps at its upper end horizontally from left to right. The longitudinal gap between the two limiting plates 3 is slightly larger than the maximum diameter of the plastic bottle caps. The two limiting plates 3 cooperate with each other to longitudinally limit the plastic bottle caps as they move from left to right with the chain plate of the conveyor 1. The bottle caps are sorted and conveyed to the right in a single row. During the process, the microcontroller 2 activates laser sensor 442 and laser sensor 443. Both laser sensors 442 and 443 emit light signals that illuminate the upper surface of the conveyor chain plate on the vertically downward side and are reflected back to their initial positions. The vertical distance between the two sensors is measured based on the propagation time and speed of the light signals, and the measurement result is transmitted to the microcontroller 2 as an electrical signal. The lateral distance between the laser emission points of laser sensors 442 and 443 is half the maximum diameter of the bottle cap, and laser sensor 443 is longitudinally aligned with the closed surfaces of the two laterally adjacent inclined sliding plates 42. When the plastic bottle cap passes by laser sensor 443, the distance measurement result of laser sensor 443 changes. When the plastic bottle cap passes by laser sensor 442, the ranging result of laser sensor 442 changes. The microcontroller 2 then compares the ranging changes of laser sensor 442 and laser sensor 443. If the difference between the two is close to the thickness of the plastic bottle cap, the bottle cap is considered defective because the bottom is facing upwards. The microcontroller 2 then activates the electro-hydraulic actuator 452, causing its extension end to move the rejection seat 453 longitudinally backwards. During this backward movement, the rejection seat 453 causes the guide rod 454 to slide adaptively along the corresponding circular hole. This sliding connection between the two supports the radial pressure applied to the extension end of the electro-hydraulic actuator 452 by the rejection seat 453, thus preventing the extension end of the electro-hydraulic actuator 452 from being damaged. When radial pressure causes damage, the diameter of the guide rod 454 is the same as the diameter of the first circular hole. When the rejection seat 453 moves longitudinally backward a certain position, the left and right edges of the rear end of the rejection seat 453 press against the inclined surface of the corresponding inclined slide plate 42 on the front side. The inclined surface of the inclined slide plate 42 on the front side slides into the corresponding groove 41 under pressure to avoid a misalignment. The telescopic end of the telescopic column 47 and the spring 48 retract. The inclined slide plate 42 on the front side drives the inclined slide plate 42 on the rear side to move synchronously through the synchronizing rod 43. The two adjacent inclined slide plates 42 on the lateral side separate and open. Then, the rear groove of the rejection seat 453 contacts the outer arc surface of the plastic bottle cap placed in the opposite direction at this position. The contact pressure pushes the unqualified plastic bottle cap backward to the conveyor plate 49 for discharge.The diameter of the rear groove of the rejection seat 453 is larger than the maximum diameter of the plastic bottle cap, thus ensuring that the plastic bottle cap can be placed in the rear groove of the rejection seat 453 during the longitudinal backward movement of the rejection seat 453. The upper rear end of the conveyor 1 is provided with an inclined plate. The inclined plate guides the plastic bottle cap to move longitudinally backward from the chain plate to the upper rear edge of the conveyor 1 and enter the chute plate 49. When the rejection seat 453 moves the unqualified plastic bottle cap to the chute plate 49, the left and right sides of the front of the rejection seat 453 are still in a state of compression contact with the corresponding inclined slide plate 42. Then, the microcontroller 2 controls the extension end of the electro-hydraulic push rod 452 to drive the rejection seat 453 to move forward longitudinally and reset. The compression and reset force of the spring 48 causes the inclined slide plate 42 on the front side to drive the inclined slide plate 42 on the rear side to reset along the corresponding groove 41 through the synchronous rod 43, thereby automatically sealing the opening and closing part of the limit plate 3. The microcontroller 2, according to its own timing unit and in combination with the extension of the electro-hydraulic push rod 452, controls the extension end of the chute plate 453 to reset the rejection seat 453. The speed of movement of the retractable end per unit time is used to regulate the extension and reset stroke of the telescopic end of the electro-hydraulic actuator 452. When the plastic bottle cap moves to the connecting seat 5 along with the chain plate of the conveyor 1, the arc-shaped limiting seat 6 limits the plastic bottle cap to the right at this position. At the same time, the microcontroller 2 activates the photoelectric sensor 7. The photoelectric sensor 7 is a through-beam type. When the plastic bottle cap passes through the through-beam gap of the photoelectric sensor 7, the electrical signal transmitted by the photoelectric sensor 7 to the microcontroller 2 changes. Subsequently, the microcontroller 2 shuts down the conveyor 1. After the plastic bottle cap in the arc-shaped limiting seat 6 is removed by the external device on the right side of the device, the microcontroller 2 starts the conveyor 1 again to continue conveying the plastic bottle cap in the arc-shaped limiting seat 6 using the same principle. After the device has been used for a period of time, the connecting seat 3 46 and its connecting elements are completely removed and replaced. The connecting seat 3 46 is fixed to the corresponding limiting plate 3 with screws to prevent the spring 48 on the right side of the connecting seat 3 46 from aging.

[0030] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STC15, the conveyor 1 can be a GB6074 chain conveyor, the laser sensor 442 and the laser sensor 443 can both be E3C-LDA6, the electro-hydraulic actuator 452 can be a DYZW integral straight micro electro-hydraulic actuator, and the photoelectric sensor 7 can be an E3Z through-beam photoelectric sensor. The microcontroller 2 controls the operation of the conveyor 1, the laser sensor 442, the laser sensor 443, the electro-hydraulic actuator 452, and the photoelectric sensor 7 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
