Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of packaging, and particularly to an automatic barrel mouth capping device for packaging barrels. Background Art
[0002] Packaging barrels are widely used in the packaging of liquid products in various industries, such as edible oil, sauces, juices, solvents, coatings, waterproof materials, etc. Usually, after the above-mentioned liquid products are filled, they are finally sealed with a film at the barrel mouth and then capped. However, at present, the final capping process of packaging barrels mainly relies on manual labor. Especially for the sorting of barrel lids, it mainly relies on workers to turn the barrel lids one by one so that the openings of the barrel lids face down for subsequent manual or machine capping. When capping with a machine, generally, the packaging barrel also needs to be stationary to facilitate the machine to align with the barrel mouth for capping. Therefore, the above capping method has a high labor cost, and due to the frequent stop of the packaging barrel during transmission, the packaging efficiency is relatively low. Summary of the Invention
[0003] To solve the problems of high capping cost and low efficiency of packaging barrels in the prior art, the present invention provides an automatic barrel mouth capping device for packaging barrels. This device realizes the automatic sorting of barrel lids through a lid sorting system, and can complete the capping operation without the packaging barrel being stationary during capping through a synchronous moving mechanism.
[0004] The technical solution adopted by the present invention is as follows:
[0005] An automatic barrel mouth capping device for packaging barrels includes a conveying system for conveying packaging barrels, a capping system for capping the barrel mouths of packaging barrels, and a lid sorting system for cooperating with the capping system; the capping system includes a synchronous moving mechanism, a rotation driving mechanism, and a lid grasping mechanism. The synchronous moving mechanism is connected to the lid grasping mechanism to drive the lid grasping mechanism to move synchronously with the packaging barrel on the conveyor belt. The rotation driving mechanism is connected to the lid grasping mechanism to drive the lid grasping mechanism to rotate for capping. The lid grasping mechanism is used to grasp the barrel lids in the lid sorting system and install them at the barrel mouths of the packaging barrels.
[0006] Preferably, the lid sorting system includes a lid storage box, a lid taking mechanism, and a lid feeding track; the lid taking mechanism includes a chain plate conveyor belt. The chain plate conveyor belt is arranged on one side of the lid storage box. A plurality of supporting cover plates are arranged on the chain plate conveyor belt. The side of the chain plate conveyor belt facing the middle of the lid storage box moves from bottom to top. When the supporting cover plates pass through the lid storage box, they lift the barrel lids with the lid openings facing the middle of the lid storage box. The top of the chain plate conveyor belt on the side facing the lid storage box has an unloading lid part that slopes from bottom to top towards the lid storage box. One end of the lid feeding track is arranged below the side of the unloading lid part facing the middle of the lid storage box, and the other end of the lid feeding track extends downward to the below of the lid grasping mechanism.
[0007] Preferably, the synchronous moving mechanism includes a first servo motor, a lead screw, a limiting rod, a first telescopic mechanism, and a barrel mouth detector. The output shaft of the first servo motor is connected to the lead screw. A base is threadedly connected to the lead screw. The limiting rod is arranged parallel to the lead screw and penetrates through the base and is slidably connected to the base. The first telescopic mechanism is arranged on the base. The lid grasping mechanism is connected to the first telescopic mechanism through a rotary driving mechanism and is driven by the first telescopic mechanism to move up and down. The barrel mouth detector is arranged on one side of the conveying system for detecting the mouth of the packaging barrel. When the mouth of the packaging barrel passes by the barrel mouth detector, the first servo motor is started to drive the lead screw to drive the base to move at the same speed and in the same direction as the conveying system.
[0008] Preferably, the rotary driving mechanism includes a second servo motor. The second servo motor is connected to the first telescopic mechanism and is driven by the first telescopic mechanism to move up and down. The output shaft of the second servo motor is connected to the lid grasping mechanism and drives the lid grasping mechanism to rotate.
[0009] Preferably, the lid grasping mechanism includes a clamping seat and clamping pieces. The clamping seat is connected to the output shaft of the second servo motor. A plurality of clamping pieces are arranged on the outer side of the bottom of the clamping seat. The upper ends of the clamping pieces are rotatably connected to the clamping seat, and an elastic member is connected between the upper ends of the clamping pieces and the clamping seat.
[0010] Preferably, the lid sorting system further includes a weight sensor, a barrel lid detector, and a second telescopic mechanism. The weight sensor is arranged at the bottom of the lid storage box. The barrel lid detector is arranged on the lid feeding track. The two ends of the top of the side of the lid storage box opposite to the chain plate conveyor are respectively rotatably connected to the adjacent two side walls. The two ends of the bottom of the lid storage box close to the chain plate conveyor are respectively rotatably connected to the adjacent two side walls. The bottom of the lid storage box far from the chain plate conveyor and the side of the lid storage box opposite to the chain plate conveyor are slidably connected, and the sliding direction is along the vertical direction. The second telescopic mechanism is arranged at the bottom of the lid storage box to push the bottom of the lid storage box to rotate.
[0011] The beneficial effects of the present invention are as follows:
[0012] The lid sorting system sorts the barrel lids and cooperates with the lid covering system for automatic lid covering. The synchronous moving mechanism drives the lid grasping mechanism to grasp the lid and then move synchronously with the packaging barrel during lid covering, so that the rotary driving mechanism drives the lid grasping mechanism to rotate to accurately complete the lid covering operation, saving the labor cost of covering the packaging barrel and improving the efficiency of covering the packaging barrel.

Detailed implementation manners
[0018] The present invention will be described in detail below with reference to the drawings and embodiments.
[0019] Embodiment
[0020] An automatic barrel mouth capping device for a packaging barrel, comprising a conveyor system 1 for conveying the packaging barrel, an upper cover system 2 for capping the barrel mouth of the packaging barrel, and a cover sorting system 3 for cooperating with the upper cover system 2; the upper cover system 2 includes a synchronous movement mechanism 4, a rotation drive mechanism 5, and a cover grasping mechanism 6, the synchronous movement mechanism 4 is connected to the cover grasping mechanism 6 for driving the cover grasping mechanism 6 to move synchronously with the packaging barrel on the conveyor belt, the rotation drive mechanism 5 is connected to the cover grasping mechanism 6 for driving the cover grasping mechanism 6 to rotate for capping, and the cover grasping mechanism 6 is used for grasping the barrel cover in the cover sorting system 3 and installing it at the barrel mouth of the packaging barrel.
[0021] Taking the packaging with edible oil as an example for illustration, the packaging barrel is conveyed on the conveying system 1, and the conveying system 1 can be a conveyor belt. Of course, the device can also include a filling system and a heat-sealing system. The filling system belongs to the prior art and will not be elaborated too much. The filling system, the heat-sealing system, the lid sorting system 3 and the lid covering system 2 are arranged in sequence along the conveying direction of the conveying system 1. The heat-sealing system is used to seal the mouth of the packaging barrel with a film. The heat-sealing system can include two hot air guns, which are respectively arranged on both sides of the conveying system 1. The height of the air outlet of the hot air gun corresponds to the height of the mouth of the passing packaging barrel. After filling, an annular heat-sealing film can be sleeved on the mouth of the packaging barrel manually or by a machine. When the packaging barrel with the heat-sealing film passes by the hot air gun, it is heated by the hot air blown out by the hot air gun and then shrinks and fits on the mouth of the packaging barrel. Of course, to prevent the heat-sealing film from being blown off, a certain amount of viscous substance, such as edible glue, etc., can be covered at the bottom of the inner circle of the heat-sealing film, and only a small amount is needed to make the viscosity sufficient to prevent the heat-sealing film from being blown off by the hot air. The lid sorting system 3 sorts out the barrel lids, and the lid grasping mechanism 6 takes the barrel lids from the lid sorting mechanism. When the packaging barrel enters the position of the lid covering system 2, the synchronous moving mechanism 4 drives the lid grasping mechanism 6 to move synchronously with the packaging barrel, so that the barrel lid is kept directly above the mouth of the barrel, and then the rotation driving mechanism 5 drives the lid grasping mechanism 6 to rotate to screw the barrel lid onto the mouth of the barrel.
[0022] In one of the embodiments, the lid sorting system 3 includes a lid storage box 7, a lid taking mechanism 8 and a lid feeding track 9; the lid taking mechanism 8 includes a chain plate conveyor belt 10, the chain plate conveyor belt 10 is arranged on one side of the lid storage box 7, a plurality of supporting cover plates 11 are arranged on the chain plate conveyor belt 10, the side of the chain plate conveyor belt 10 facing the middle of the lid storage box 7 moves from bottom to top, and when the supporting cover plate 11 passes by the lid storage box 7, it lifts the barrel lid with the lid opening facing the middle of the lid storage box 7. The top of the chain plate conveyor belt 10 has a lid discharging part 12 that slopes from bottom to top and towards the lid storage box 7 on the side facing the lid storage box 7. One end of the lid feeding track 9 is arranged below the side of the lid discharging part 12 facing the middle of the lid storage box 7, and the other end of the lid feeding track 9 extends downward to below the lid grasping mechanism 6.
[0023] The barrel cover is placed in the cover storage box 7. The cover storage box 7 can have an opening on one side of the bottom for the chain plate conveyor belt 10 to pass through, or an opening on one side wall of the cover storage box 7 for the chain plate conveyor belt 10 to pass through. The depth of the supporting cover plate 11 is slightly less than the height of the barrel cover to prevent the barrel cover from falling through the hole for the supporting cover plate 11 to pass through. As the chain plate conveyor belt 10 operates, when the supporting cover plate 11 enters the cover storage box 7, the supporting cover plate 11 will lift some barrel covers. Since the weight on one side of the cover opening of the barrel cover is less than that on the other side, the barrel covers with the cover openings away from the chain plate conveyor belt 10 will be continuously supported by the supporting cover plate 11, while the barrel covers in other orientations will fall from the supporting cover plate 11 under the action of gravity. When the supporting cover plate 11 lifts the barrel cover to the cover unloading part 12, due to the inclination of the cover unloading part 12, the barrel cover will fall from the supporting cover plate 11 onto the cover feeding track 9 under the action of gravity, and the cover opening is downward. Then it slides down along the cover feeding track 9 to the lower part of the cover grasping mechanism 6. Limit plates are provided on both sides of the cover feeding track 9 to prevent the barrel cover from sliding out of the cover feeding track 9, and a limit plate is also provided at one end of the cover feeding track 9 located under the cover grasping mechanism 6. The overall height of the cover feeding track 9 gradually decreases so that the barrel cover can slide downward under the action of gravity. Its top end is first perpendicular to the conveying direction of the conveying system 1, and then gradually rotates 90 degrees and then slopes downward along the conveying direction to the lower part of the cover grasping mechanism 6.
[0024] In one embodiment, the synchronous moving mechanism 4 includes a first servo motor 13, a lead screw 14, a limit rod 15, a first telescopic mechanism 16 and a barrel mouth detector 17. The output shaft of the first servo motor 13 is connected to the lead screw 14. A base 18 is threadedly connected to the lead screw 14. The limit rod 15 is arranged parallel to the lead screw 14. The limit rod 15 passes through the base 18 and is slidably connected to the base 18. The first telescopic mechanism 16 is arranged on the base 18. The cover grasping mechanism 6 is connected to the first telescopic mechanism 16 through a rotation driving mechanism 5 and is driven by the first telescopic mechanism 16 to move up and down. The barrel mouth detector 17 is arranged on one side of the conveying system 1 for detecting the barrel mouth of the packaging barrel. When the barrel mouth of the packaging barrel passes by the barrel mouth detector 17, the first servo motor 13 is started to drive the lead screw 14 to drive the base 18 to move at the same speed and in the same direction as the conveying system 1.
[0025] The servo motor 13 drives the lead screw 14 to rotate, which can drive the base 18 to move. The lead screw 14 and the limit rod 15 are arranged along the conveying direction of the conveying system 1. According to the different rotation directions of the output shaft of the servo motor, the moving direction of the base 18 is also different. The lid grasping mechanism 6 is initially at one end of the lid feeding track 9 located below it. The first telescopic mechanism 16 first lowers the lid grasping mechanism 6 to grasp the barrel lid below, and then raises the lid grasping mechanism 6 to return to its original position. The position of the barrel mouth detector 17 is set such that when the barrel mouth is exactly below the barrel lid, the barrel mouth can be detected, that is, it can detect the side of the barrel mouth facing the downstream of the conveying system 1. The barrel mouth detector 17 can be an infrared sensor. When the barrel mouth detector 17 detects the barrel mouth, the servo motor rotates forward to drive the base 18 to move in the same direction as the packaging barrel, keeping the barrel lid grasped by the lid grasping mechanism 6 directly above the barrel mouth for lid covering. After the lid grasping mechanism 6 translates for a period of time, when the lid grasping mechanism 6 and the end of the lid feeding track 9 close to the lid grasping mechanism 6 are completely staggered vertically, the first telescopic mechanism 16 drives the lid grasping mechanism 6 to descend, and at the same time, the rotary drive mechanism 5 drives the lid grasping mechanism 6 to rotate for lid covering. When the rotary drive mechanism 5 drives the lid grasping mechanism 6 to rotate for a certain preset time and the lid covering is completed, the rotary drive mechanism 5 stops working. The first telescopic mechanism 16 drives the lid grasping mechanism 6 to rise and return to its original position and then stops working. The servo motor 13 rotates in reverse to drive the lid grasping mechanism 6 to move in the opposite direction to the packaging barrel and return to its original position, and then the above operations are repeated cyclically for the next lid covering. The distance between adjacent packaging barrels is controlled upstream of the conveying system 1 so that the lid grasping mechanism 6 can complete the lid grasping operation before the barrel mouth detector 17 detects the next barrel mouth. In this embodiment, the first telescopic mechanism 16 can be a cylinder, a hydraulic cylinder or a linear module, etc., as long as it can meet the required lifting accuracy and reaction speed.
[0026] To ensure that the lid grasping mechanism 6 can align with the barrel mouth accurately when covering the lid and the detection of the barrel mouth detector 17 is accurate enough, the packaging barrel needs to be centered during conveying. A centering mechanism needs to be set at the position of the conveying system 1 corresponding to the lid grasping mechanism 6. The centering mechanism includes two centering rods symmetrically arranged on both sides of the conveying system 1. The centering rods are arranged along the length direction of the conveying system 1. The distance between the two centering rods is adapted to the shorter side of the packaging barrel in the horizontal direction. The two ends of the centering rods are inclined and bent outward and extend vertically to the outside of the conveying system 1. When the packaging barrel is placed on the conveying system 1, the shorter side in the horizontal direction is placed along the length direction of the conveying system 1. When the packaging barrel is conveyed, it will be guided by the inclined and bent parts of the two centering rods and restricted by the middle parts of the two centering rods on the central axis of the conveying system 1 for conveying, so that the position of the barrel mouth of the packaging barrel when passing through the barrel mouth detector 17 remains the same, avoiding the lid grasping mechanism 6 being unable to align with the barrel mouth.
[0027] In one embodiment, the rotary drive mechanism 5 includes a servo motor 19, which is connected to the telescopic mechanism 16 and driven by the telescopic mechanism 16 to move up and down. The output shaft of the servo motor 19 is connected to the cover grabbing mechanism 6 and drives the cover grabbing mechanism 6 to rotate.
[0028] In one embodiment, the cover grabbing mechanism 6 includes a clamping seat 20 and a clip 21, the clamping seat 20 is connected to the output shaft of the servo motor 219, a plurality of clips 21 are provided on the outer side of the bottom of the clamping seat 20, the upper end of the clip 21 is rotatably connected to the clamping seat 20, and an elastic member 22 is connected between the upper end of the clip 21 and the clamping seat 20.
[0029] The clamp seat 20 can be arranged vertically in a cylindrical shape, and the clip 21 is connected to the clamp seat 20 by an elastic member 22. When the inner side of the clip 21 is subjected to force, the clip 21 rotates outward, and when the force disappears, it rotates inward and resets under the action of the elastic member 22. When the cover grabbing mechanism 6 is at the end of the cover feeding track 9 below it, the telescopic mechanism 16 first lowers the cover grabbing mechanism 6. Usually, the outer diameter of the bottom opening of the barrel cover is slightly larger than the outer diameter of the top. Multiple clips 21 can be arranged equidistantly, and the inner sides are located on the same circumference. The inner diameter of the circumference is preferably larger than the outer diameter of the top of the barrel cover and smaller than the outer diameter of the bottom opening of the barrel cover. When the cover grabbing mechanism 6 is lowered, the clip 21 is stretched open by the barrel cover, thereby clamping the barrel cover, and then the telescopic mechanism raises the cover grabbing mechanism 6 to complete the grabbing of the barrel cover. After the cover is put on, the clip 21 loses the force of the barrel cover and rotates inward and resets under the action of the elastic member 22. A groove is provided on the peripheral side of the clamp seat 20, and the two ends of the upper part of the clamping piece 21 facing the clamp seat 20 are connected to the rotating shaft through the ear pieces, and the two ends of the rotating shaft are rotatably connected to the two side walls of the groove. The elastic member 22 can be selected as a torsion spring, which is assembled on the rotating shaft of the clamping piece 21, and the two ends of the torsion spring are respectively connected to the clamp seat 20 and the clamping piece 21. Generally, ribs are provided along the height direction of the peripheral side of the barrel cover for the convenience of screwing, and the width of the clamping piece 21 can be adapted to the distance between the two ribs, so as to prevent the barrel cover and the clamping piece 6 from rotating relative to each other when the barrel cover is rotated by the clamping piece 6, and a non-slip pad, such as a rubber pad, can also be provided at the inner bottom end of the clamping piece 21 where the barrel cover is clamped.
[0030] In one of the embodiments, the lid sorting system 3 further includes a weight sensor 23, a bucket lid detector 24, and a second telescopic mechanism 25. The weight sensor 23 is disposed at the bottom of the lid storage box 7, the bucket lid detector 24 is disposed on the lid feeding track 9, both ends of the top of one side of the lid storage box 7 opposite to the chain conveyor belt 10 are rotatably connected to the adjacent side walls respectively, both ends of the bottom of the lid storage box 7 close to the chain conveyor belt 10 are rotatably connected to the adjacent side walls respectively, one side of the bottom of the lid storage box 7 away from the chain conveyor belt 10 is slidably connected to the side of the lid storage box 7 opposite to the chain conveyor belt 10, and the sliding direction is along the vertical direction. The second telescopic mechanism 25 is disposed at the bottom of the lid storage box 7 to push the bottom of the lid storage box 7 to rotate.
[0031] As the supporting cover plate 11 continuously lifts the bucket lid, the number of bucket lids with the opening facing away from the side of the chain plate conveyor belt 10 will gradually decrease, or the number of bucket lids that can be easily lifted by the supporting cover plate 11 will decrease. At this time, external force is required to interfere with the orientation of the bucket lid so that the bucket lid can be easily lifted. The weight sensor 23 is used to detect the weight of the lid storage box 7, and the bucket lid detector 24 is used to detect the bucket lids passing on the lid feeding track 9. Specifically, in this embodiment, a controller is further included, and the controller is respectively connected to the weight sensor 23, the bucket lid detector 24, the second telescopic mechanism 25, and the aforementioned first servo motor 13, the first telescopic mechanism 16, the second servo motor 19, and the bucket mouth detector 17. When the lid storage box 7 is empty, the controller takes the weight detected by the weight sensor 23 as the initial weight of the lid storage box 7. Subsequently, after adding bucket lids, the controller can obtain the total weight of the bucket lids in the lid storage box 7 by subtracting the initial weight from the weight detected by the weight sensor 23. If the weight of each bucket lid is preset, the number of bucket lids can also be calculated. The bucket lid detector 24 can be arranged at one end of the lid feeding track 9 below the lid unloading part 12 for detecting the bucket lids falling from the supporting cover plate 11 onto the lid feeding track 9. When the controller detects that no bucket lid has fallen onto the lid feeding track 9 within a preset period of time according to the data of the bucket lid detector 24, and detects that the number of bucket lids in the lid storage box 7 is small (the minimum weight of the bucket lids in the lid storage box 7 can be preset) according to the data of the weight sensor 23, it reminds the operator (an audible and visual alarm can be set to be connected to the controller) to add bucket lids to the lid storage box 7. When the controller detects that no bucket lid has fallen onto the lid feeding track 9 within a preset period of time according to the data of the bucket lid detector 24, and detects that the number of bucket lids in the lid storage box 7 is large according to the data of the weight sensor 23, it means that the bucket lids in the lid storage box 7 are just not easily lifted by the supporting cover plate 11, rather than the insufficient quantity. At this time, the controller starts the second telescopic mechanism 25, and drives the bottom of the lid storage box 7 to move up and down reciprocally through the second telescopic mechanism 25. The bottom of the lid storage box 7 rotates around the rotating shaft on the side close to the chain plate conveyor belt 10, and the side of the lid storage box 7 away from the chain plate conveyor belt 10 drives the side of the lid storage box 7 opposite to the chain plate conveyor belt 10 through sliding connection, so that the side of the lid storage box 7 opposite to the chain plate conveyor belt 10 rotates around the rotating shaft at its top. When the second telescopic mechanism 25 drives the bottom of the lid storage box 7 to move upward, both the bottom of the lid storage box 7 and the side of the lid storage box 7 opposite to the chain plate conveyor belt 10 rotate towards the inside of the lid storage box 7. When the second telescopic mechanism 25 drives the bottom of the lid storage box 7 to move downward, both the bottom of the lid storage box 7 and the side of the lid storage box 7 opposite to the chain plate conveyor belt 10 rotate towards the outside of the lid storage box 7. The movement of the bottom of the lid storage box 7 and the side of the box opposite to the chain plate conveyor belt 10 drives the bucket lids in the lid storage box 7 to tumble, changing the opening orientation of the bucket lids and increasing the number of bucket lids that can be easily lifted by the supporting cover plate 11.Of course, the controller can also be connected to the chain plate conveyor belt 10. When the bucket lid detector 24 detects that there is a bucket lid continuously at one end of the lid delivery track 9 under the lid unloading part 12 for a certain period of time (slightly longer than the time for the bucket lid to slide from the end of the lid delivery track 9 under the lid unloading part 12 until it cannot be detected by the bucket lid detector 24), it means that the bucket lids on the lid delivery track 9 have piled up. Then, the chain plate conveyor belt 10 can be paused to stop lifting the bucket lid. When the bucket lid detector 24 detects that there is no bucket lid at one end of the lid delivery track 9 under the lid unloading part 12, the chain plate conveyor can be started to continue lifting the bucket lid. The controller can be a PLC or other electronic components that can implement the above control functions.
[0032] The above-described embodiments merely represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
