Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to a fully automatic packaging machine for lightning arresters. Background Art

[0002] To put a small product into a box, the original packaging line is composed of four people, who are responsible for loading, coding, checking the coding quality, and sealing the boxes. The working method is very mechanical, which tests the patience of the on-site staff. As the working hours get longer, efficiency will inevitably decrease, the staff will become tired, and the product completion and quality level will decline. Due to the small size of the product, the huge shipment volume, and the demand for the product, the current manual packaging line can no longer meet the supply demand. If an assembly line is added on site, the same problem will arise.

[0003] In addition, with the continuous improvement of my country's industrial technology level and the continuous advancement of industrialization in recent years, modern and industrialized smart factories have begun to gain widespread popularity and application. In the modern manufacturing production process, the demand for the automation level of operating equipment and operation processes is increasing day by day. Achieving full automation of industrial production has gradually become a challenge that every industrial production enterprise needs to face.

[0004] Therefore, there is an urgent need for a packaging device for fully automatic packaging of small products to meet existing supply needs. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a fully automatic packaging machine for lightning arresters. The fully automatic packaging machine for lightning arresters of the present application integrates automatic loading, coding, coding detection, automatic feeding of bottom box coils, automatic heat sealing, automatic winding of covering coils and bottom box coils, realizing fully automatic continuous packaging of small electronic products such as lightning arresters. The fully automatic packaging machine has good stability, fast packaging speed and high efficiency, and the products after packaging are in the form of coils, occupying little space and being convenient for storage and transportation.

[0007] In which, the feeding mechanism includes a material sensor, an intermittent pressing component, a vacuum component, and a feeding trough connected to the material inlet end of one of the cavities of the turntable. The material sensor is located on the side of the feeding trough, and the material sensor is used to sense whether there is a product at one end of the feeding trough close to the cavity. The intermittent pressing component is located above the feeding trough, and the intermittent pressing component is used to intermittently press against the second product located in the feeding trough close to the cavity. The suction end of the vacuum component is connected to the cavity.

[0008] The feeding mechanism of the present application uses a vacuum component to draw a vacuum to suck the product located in the feeding trough closest to the cavity into the cavity. No mechanical action mechanism is required to push the feeding quickly. The intermittent pressing component is used to press against the second product located in the feeding trough close to the cavity to prevent the second product from being sucked away, thereby ensuring continuous and stable feeding.

[0009] It also includes a connecting seat, the feed trough is opened on the connecting seat, and a sealing block for covering the cavity and the feed trough is provided above the connecting seat and the cavity; the intermittent tightening assembly includes a first voice coil motor provided above the feed trough and an abutting column connected to the output end of the first voice coil motor; the intermittent tightening assembly also includes a tightening buffer assembly, the tightening buffer assembly includes a step hole opened in the sealing block for the abutting column to pass through, a sleeve provided in the step hole, a shoulder ring provided in the middle section of the abutting column, and a tightening buffer spring clamped between the upper end surface of the sleeve and the shoulder ring, and the sleeve is sleeved outside the abutting column.

[0010] The sealing block covers the feed trough and the cavity connected to the feed trough 4. When the first voice coil motor drives the abutment column to move downward, the buffer spring can play a certain buffering role, preventing the abutment column from moving downward too quickly, reducing the impact on the product, and avoiding damage to the product when abutting against the product.

[0011] Among them, the connecting seat is provided with a first assembly hole for installing the material sensor; the sealing block is provided with a second assembly hole, the second assembly hole is located above the cavity, and a feed sensor is provided in the second assembly hole for sensing whether the product has been loaded into the cavity.

[0012] The sensing position of the feeding sensor corresponds to the end of the cavity away from the cavity opening, so that the feeding sensor can sense and check whether the product is placed in place in the cavity, thereby improving the feeding accuracy.

[0013] The vacuum pumping assembly includes an air passage connected to the bottom of the cavity, a pipe connector connected to the lower end of the air passage, and a vacuum pumping device connected to the pipe connector.

[0014] Among them, the turntable includes a disc body, a lower cover plate and an upper cover plate. The disc body is arranged in a circular saw blade structure, and the cavity between two adjacent saw teeth forms a cavity. The lower cover plate is used to cover the lower end opening of the cavity, and the upper cover plate is used to cover the upper end opening of the cavity that is not connected to the feed trough.

[0015] The feeding mechanism of the present application conveys small-volume products through the feeding trough. When the material sensor senses the presence of a product at one end of the feeding trough close to the cavity, the vacuum component draws a vacuum to suck the product closest to the cavity in the feeding trough into the cavity, completing the feeding work. The driving component drives the turntable to rotate, and the next empty cavity reaches the feeding trough for connection. At the same time, the intermittent pressing component presses against the second product close to the cavity in the feeding trough to prevent the second product from being sucked away, thereby ensuring normal feeding. When the material sensor senses the absence of a product at one end of the feeding trough close to the cavity, the intermittent pressing component separates from the second product, and the second product moves along the feeding trough to the end of the feeding trough close to the cavity, and so on. This realizes continuous feeding of products, and the feeding is fast and stable.

[0016] It also includes a driving assembly for driving the driving wheel to rotate, and the wheel surface of the driving wheel is convexly provided with a circle of plug-in bodies that are matched with the bottom box coil.

[0017] One side edge of the bottom box coil and the cover coil is provided with plugging through holes for inserting the plug-in body at equal intervals.

[0019] Among them, the heat sealing assembly includes a guide seat and two sets of heat sealing pressing mechanisms. The guide seat is provided with a guide groove for the bottom box coil to pass through, and the two sets of heat sealing pressing mechanisms are symmetrically arranged on both sides of the guide groove; the heat sealing pressing mechanism includes a heating seat, a pressing block fixed to the heating seat, and a reciprocating drive mechanism for driving the pressing block to intermittently press one side of the covering coil. The heating seat is penetrated by a heating wire.

[0021] The output end of the swing cylinder reciprocates and contracts, thereby driving the end of the swing arm close to the heating seat to swing back and forth up and down, and then driving the heating seat and the pressing block to reciprocate up and down, to achieve intermittent pressing of one side of the covering coil, the heating wire heats the heating seat, and the heating seat transfers heat to the pressing block, and when the pressing block presses the covering coil and the bottom box coil, the heat is instantly transferred to the covering coil, so that the covering coil and the bottom box coil at the pressing position are bonded together.

[0022] The feeding mechanism includes a third mounting seat, a second voice coil motor fixed to the third mounting seat, and a ejector pin fixed to the output end of the second voice coil motor, and the ejector pin is located above one of the cavities of the turntable and the bottom box roll.

[0023] The second voice coil motor works to drive the ejector to move downward. The ejector passes through the cavity and pushes the arrester in the cavity into the small box of the bottom box coil, completing a feeding action. This reciprocating action continuously feeds the moving bottom box coil.

[0024] The ejector pin is fixed with a shaft shoulder piece, the ejector pin passes through the third mounting seat, a buffer compression spring is provided on the outer sleeve of the ejector pin, and the buffer compression spring is clamped between the third mounting seat and the shaft shoulder piece.

[0025] The arrangement of the buffer compression spring can play a role in shock absorption and enhance the running stability of the ejector.

[0026] A pressing roller assembly is provided above the driving wheel. The pressing roller assembly includes a roller and a linear drive structure for driving the roller to move downward and squeeze the heat-sealed cover roll. The roller and the driving wheel are in contact with each other.

[0027] A wheel surface groove is provided in the middle of the driving wheel for the small box of the bottom box coil to pass through. The driving wheel surfaces located on both sides of the wheel surface groove abut against the lower surfaces of both sides of the bottom box coil. Correspondingly, the rollers press downward against the upper surfaces of both sides of the covering coil, so that the driving wheel and the rollers cooperate to complete the edge sealing, pressing and leveling work of the bottom box coil and the covering coil.

[0028] Among them, the driving component includes a servo motor and an output shaft fixed to the output end of the servo motor, the driving wheel is fixed to the output shaft, the output shaft is also fixed with an active winding wheel, the winder is connected to a winding shaft, the winding shaft is fixed with a driven winding wheel, and a belt is connected between the active winding wheel and the driven winding wheel.

[0029] The winding speed of the reel is slightly greater than the linear speed of the driving wheel, so that the driving wheel and the reel can use the same servo motor as a power source.

[0030] It also includes a first sensor, a second sensor, an alarm and a controller. The first sensor is located above the bottom box roll, and the second sensor is located on the side of the bottom box roll. The first sensor, the second sensor, the drive component, the material sensor, the intermittent abutment component, the vacuum component, the first voice coil motor, the feeding sensor, the heat sealing component, the second voice coil motor, the stroke sensing switch, the pressure roller component, and the servo motor are all electrically connected to the controller.

[0031] Wherein, the lower cover is provided with a notch that reveals at least one cavity, and a defective product recovery box is provided below the notch. Along the rotation direction of the turntable: the notch is located behind the feeding mechanism.

[0032] The CCD detection component captures the inkjet coding pattern on the surface of the lightning arrester, detects whether the inkjet coding pattern is qualified, and records whether the product is qualified or unqualified. The turntable rotates to send the lightning arrester detected by the CCD detection component to the bottom of the feeding mechanism. If the lightning arrester is a recorded qualified product, the feeding mechanism will push the lightning arrester in the cavity into the small box corresponding to the bottom box coil. If the lightning arrester is a recorded unqualified product, the feeding mechanism will not work, and the unqualified product will leave the working station of the feeding mechanism as the turntable rotates. The unqualified product enters the top of the recycling box, falls through the gap to the recycling box and is collected.

[0033] The first sensor provided in the fully automatic packaging machine for lightning arresters of the present application can sense whether a lightning arrester is loaded in the bottom box coil to avoid empty packaging. The second sensor is located on the side of the bottom box coil and can read the number of small boxes passing through the bottom box coil, thereby obtaining the traveling speed of the bottom box coil and comparing it with the linear speed of the wheel surface of the driving wheel. When a difference occurs, the alarm is triggered to send an alarm signal so that the operator can discover and adjust it in time.

[0034] The beneficial effects of the present invention are as follows: the vibration disk of the present invention automatically completes the material sorting work of the lightning arrester and transports the lightning arrester to the feeding mechanism, the feeding mechanism accurately puts the lightning arrester into the corresponding cavity of the turntable, the driving component drives the turntable to rotate, the turntable transports the lightning arrester to the bottom of the inkjet component, the inkjet component sprays the code on the lightning arrester located below, and after the coding is completed, the turntable sends the lightning arrester to the bottom of the CCD detection component, the CCD detection component captures the coding pattern on the surface of the lightning arrester, detects whether the coding pattern is qualified, and records whether the product is a qualified product or an unqualified product, the bottom box unwinder, the cover unwinder, The winder and the driving wheel work, driving the bottom box coil and the covering coil to move forward. The turntable rotates to send the lightning arrester detected by the CCD detection component to the bottom of the feeding mechanism. If the lightning arrester is a qualified product recorded, the feeding mechanism works to push the lightning arrester in the cavity into the small box corresponding to the bottom box coil. If the lightning arrester is an unqualified product recorded, the feeding mechanism does not work, and the unqualified product leaves the working station of the feeding mechanism as the turntable rotates. The heat sealing component completes the heat sealing of the covering coil and the bottom box coil, and the winder rewinds the heat-sealed bottom box coil, and the packaging work of the lightning arrester continues in this way.

The inkjet coding component 6, CCD detection component 7 and feeding mechanism 8 are all located above the turntable 2 and are arranged in sequence along the rotation direction of the turntable 2.

[0055] Among them, the feeding mechanism 5 includes a material sensor 15, an intermittent pressing component 16, a vacuum component 17, and a feeding trough 14 connected to the material inlet end of one of the cavities 69 of the turntable 2. The material sensor 15 is located on the side of the feeding trough 14. The material sensor 15 is used to sense whether there is a product 34 at the end of the feeding trough 14 close to the cavity 69. The intermittent pressing component 16 is located above the feeding trough 14. The intermittent pressing component 16 is used to intermittently press against the second product 34 located in the feeding trough 14 close to the cavity 69. The suction end of the vacuum component 17 is connected to the cavity 69.

[0056] The feeding mechanism 5 of the present application uses a vacuum component to draw a vacuum to suck the product 34 located in the feeding trough 14 closest to the cavity 69 into the cavity 69. No mechanical action mechanism is required to push the feeding quickly. The intermittent pressing component 16 is used to press against the second product 34 located in the feeding trough 14 close to the cavity 69 to prevent the second product 34 from being sucked away, thereby ensuring the continuous and stable feeding operation.

[0057] Among them, it also includes a connecting seat 18, the feed trough 14 is opened on the connecting seat 18, and a sealing block 19 for covering the cavity 69 and the feed trough 14 is provided above the connecting seat 18 and the cavity 69; the intermittent tightening assembly 16 includes a first voice coil motor 20 provided above the feed trough 14 and an abutting column 21 connected to the output end of the first voice coil motor 20; the intermittent tightening assembly 16 also includes a tightening buffer assembly, the tightening buffer assembly includes a step hole 22 opened in the sealing block 19 for the abutting column 21 to pass through, a sleeve 23 provided in the step hole 22, a shoulder ring 24 provided in the middle section of the abutting column 21, and a tightening buffer spring 25 clamped between the upper end surface of the sleeve 23 and the shoulder ring 24, and the sleeve 23 is sleeved outside the abutting column 21.

[0058] The sealing block 19 covers the feed trough 14 and the cavity 69 connected to the feed trough 144. When the first voice coil motor 20 drives the abutment column 21 to move downward, the buffer spring 25 can play a certain buffering role, preventing the abutment column 21 from moving downward too quickly, reducing the impact on the product 34, and avoiding damage to the product 34 when abutting against the product 34.

[0059] Among them, the connecting seat 18 is provided with a first assembly hole 32 for installing the material sensor 15; the sealing block 19 is provided with a second assembly hole 33, the second assembly hole 33 is located above the cavity 69, and the second assembly hole 33 is provided with a feed sensor 26 for sensing whether the product 34 has been loaded into the cavity 69.

[0060] The sensing position of the feeding sensor 26 corresponds to the end of the cavity 69 away from the opening of the cavity 69, so that the feeding sensor 26 can sense and check whether the product 34 is placed in place in the cavity 69, thereby improving the feeding accuracy.

[0061] The vacuum assembly 17 includes an air passage 27 connected to the bottom of the cavity 69 , a pipe connector 28 connected to the lower end of the air passage 27 , and a vacuum device connected to the pipe connector 28 .

The lower cover plate 30 is used to cover the lower end opening of the cavity 69, and the upper cover plate 31 is used to cover the upper end opening of the cavity 69 that is not connected to the feed trough 14.

[0063] The feeding mechanism 5 of the present application conveys small-volume products 34 through the feeding trough 14. When the material sensor 15 senses the presence of a product 34 at one end of the feeding trough 14 close to the cavity 69, the vacuum component draws a vacuum to suck the product 34 closest to the cavity 69 in the feeding trough 14 into the cavity 69, completing the feeding work. The driving component 3 drives the turntable 2 to rotate, and the next empty cavity 69 reaches the feeding trough 14 for connection. At the same time, the intermittent pressing component 16 presses against the second product 34 close to the cavity 69 in the feeding trough 14 to prevent the second product 34 from being sucked away, thereby ensuring normal feeding. When the material sensor 15 senses the absence of a product 34 at one end of the feeding trough 14 close to the cavity 69, the intermittent pressing component 16 separates from the second product 34, and the second product 34 moves along the feeding trough 14 to the end of the feeding trough 14 close to the cavity 69, and so on. Continuous feeding of products 34 is achieved, and feeding is fast and stable.

[0064] The driving wheel 13 further comprises a driving assembly 38 for driving the driving wheel 13 to rotate. The wheel surface of the driving wheel 13 is convexly provided with a circle of plug-in bodies 39 that are matched with the bottom box coil.

[0066] Among them, a bottom box coil guide assembly 40 is provided between the bottom box unwinder 9 and the feeding mechanism 8, and a cover coil guide assembly 41 is provided between the cover unwinder 10 and the heat sealing assembly 12.

[0067] Among them, the heat sealing assembly 12 includes a guide seat 43 and two sets of heat sealing and pressing mechanisms 42. The guide seat 43 is provided with a guide groove 44 for the bottom box coil to pass through, and the two sets of heat sealing and pressing mechanisms 42 are symmetrically arranged on both sides of the guide groove 44; the heat sealing and pressing mechanism 42 includes a heating seat 45, a pressing block 46 fixed to the heating seat 45, and a reciprocating drive mechanism for driving the pressing block 46 to intermittently press one side of the covering coil. The heating seat 45 is penetrated by a heating wire 47.

[0069] The output end of the swing cylinder 50 reciprocates and contracts, thereby driving the end of the swing arm 49 close to the heating seat 45 to swing back and forth, and then driving the heating seat 45 and the pressing block 46 to move back and forth, thereby realizing intermittent pressing of one side of the covering coil. The heating wire 47 heats the heating seat 45, and the heating seat 45 transfers heat to the pressing block 46. When the pressing block 46 presses the covering coil and the bottom box coil, the heat is instantly transferred to the covering coil, so that the covering coil and the bottom box coil at the pressing position are bonded together.

[0071] The second voice coil motor 53 works to drive the ejector 54 to move downward. The ejector 54 passes through the cavity 69 and pushes the lightning arrester in the cavity 69 into the small box of the bottom box coil, completing one feeding action. This reciprocating action continues to feed the moving bottom box coil.

The wheel surfaces of the driving wheel 13 located on both sides of the wheel surface groove are in contact with the lower surfaces of both sides of the bottom box coil. Correspondingly, the rollers 59 press downward against the upper surfaces of both sides of the covering coil, so that the driving wheel 13 and the rollers 59 cooperate to complete the edge sealing, pressing and leveling work of the bottom box coil and the covering coil.

[0076] Among them, the driving component 38 includes a servo motor 61 and an output shaft 62 fixed to the output end of the servo motor 61, the driving wheel 13 is fixed to the output shaft 62, and the output shaft 62 is also fixed with an active winding wheel 63, the winding device 11 is connected to a winding shaft 64, and the winding shaft 64 is fixed with a driven winding wheel 65, and a belt 66 is connected between the active winding wheel 63 and the driven winding wheel 65.

[0078] It also includes a first sensor 35, a second sensor 36, an alarm 37 and a controller 67.

The turntable 2 rotates to send the arrester detected by the CCD detection component 7 to the bottom of the feeding mechanism 8. If the arrester is a recorded qualified product 34, the feeding mechanism 8 will work to push the arrester in the cavity 69 into the small box corresponding to the bottom box coil. If the arrester is a recorded unqualified product 34, the feeding mechanism 8 will not work, and the unqualified product 34 will leave the working station of the feeding mechanism 8 as the turntable 2 rotates. The unqualified product enters the top of the recovery box, falls into the recovery box through the gap 68 and is collected.

[0081] The first sensor 35 provided in the fully automatic packaging machine for lightning arresters of the present application can sense whether a lightning arrester is loaded in the bottom box coil to avoid empty packaging. The second sensor 36 is located on the side of the bottom box coil and can read the number of small boxes passing through the bottom box coil, thereby obtaining the traveling speed of the bottom box coil and comparing it with the linear speed of the wheel surface of the driving wheel 13. When a difference occurs, the alarm 37 is triggered to send an alarm signal so that the operator can discover and adjust it in time.

[0082] The beneficial effects of the present invention are as follows: the vibration disk 4 of the present invention automatically completes the material sorting work of the lightning arrester and conveys the lightning arrester to the feeding mechanism 5, the feeding mechanism 5 accurately puts the lightning arrester into the corresponding cavity 69 of the turntable 2, the driving component 3 drives the turntable 2 to rotate, the turntable 2 conveys the lightning arrester to the bottom of the coding component 6, the coding component 6 codes the lightning arrester located below, after the coding is completed, the turntable 2 conveys the lightning arrester to the bottom of the CCD detection component 7, the CCD detection component 7 captures the coding pattern on the surface of the lightning arrester, detects whether the coding pattern is qualified, and records whether the product 34 is a qualified product 34 or an unqualified product 34, the bottom box unwinder 9, the cover unwinder 10, The winder 11 and the driving wheel 13 work, driving the bottom box coil and the covering coil to move forward. The turntable 2 rotates to send the lightning arrester detected by the CCD detection component 7 to the bottom of the feeding mechanism 8. If the lightning arrester is a recorded qualified product 34, the feeding mechanism 8 works to push the lightning arrester in the cavity 69 into the small box corresponding to the bottom box coil. If the lightning arrester is a recorded unqualified product 34, the feeding mechanism 8 does not work, and the unqualified product 34 leaves the working station of the feeding mechanism 8 as the turntable 2 rotates. The heat sealing component 12 completes the heat sealing of the covering coil and the bottom box coil, and the winder 11 winds up the heat-sealed bottom box coil, and the packaging work of the lightning arrester continues in this way.

[0083] The fully automatic packaging machine for lightning arresters of the present invention integrates automatic loading, coding, coding detection, automatic feeding of bottom box coils, automatic heat sealing, automatic winding of cover coils and bottom box coils, realizing fully automatic continuous packaging of small electronic products 34, such as lightning arresters. The fully automatic packaging machine has good stability, fast packaging speed and high efficiency. After packaging, the product 34 is in the form of a coil, occupies little space, and is convenient for storage and transportation.

[0084] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
