Description

Technical Field

[0001] This invention relates to the field of adhesive filling equipment technology, and in particular to an automatic adhesive filling device and filling method. Background Technology

[0002] Adhesives used in industrial or residential applications, such as glass glue, silicone, and structural adhesives, are often designed as long, cylindrical rigid tubes. The common adhesive production process begins with the processing of the rigid tube, including sealing the tube head and applying a film to the outer wall. The bottom of the tube remains open, and the tube is fed onto a dispensing machine with the bottom opening facing upwards for dispensing. After dispensing, the opening is sealed with a cap, thus completing the adhesive production. Existing technologies include, for example, Chinese patent document CN115010073A, which discloses a filling system and method for resin adhesive production, and Chinese patent document CN114906785B, which discloses an adhesive... Automatic filling equipment with controllable dispensing for pharmaceutical production can achieve automated filling and improve production efficiency. However, the capping caps used for capping consist of an integrally connected hollow cylindrical part and a hollow conical part. Considering the capping force and sealing requirements, they are mostly automatically capped by machines. The caps that are randomly conveyed may be in a flat position with the opening facing up, a flat position with the opening facing down, or a side-standing position with the opening facing outward. How to keep the cap in a flat position with the opening facing up during the capping process becomes a problem. Manual support is inefficient, and considering that the caps are small in size and irregular in shape, it is also difficult to use a robotic arm to grasp them in a directional manner. Therefore, it is not conducive to further improving the efficiency of automated filling. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an automatic adhesive filling device and filling method to solve the problem of low capping efficiency in existing automatic adhesive filling processes.

[0004] To achieve the above objectives, the present invention provides an automatic adhesive filling device, including a machine base, a material tank on one side of the machine base for holding paste-like adhesive material, a discharge pipe connected to the material tank, and a turntable on the machine base for holding rigid tubes. The material is poured into the rigid tubes through the discharge pipe.

[0005] The turntable is connected to the machine base. Multiple tube holes are spaced around the circumference of the turntable. One end of the rigid tube is open. The machine base is equipped with upper tube position, filling position, capping position and lower tube position at each tube hole. The turntable rotates intermittently. When the tube hole is rotated to the upper tube position in sequence, the rigid tube is inserted into the tube hole with the opening of the rigid tube facing upward. When the tube hole rotates intermittently to the filling position, the material is poured into the rigid tube through the discharge pipe.

[0006] A capping mechanism is provided on one side of the machine, and a feed inlet is provided on one side of the capping mechanism. A feed conveyor belt is provided through the feed inlet to convey the cap into the capping mechanism. The cap includes a hollow cylindrical part and a hollow conical part. The open end of the hollow conical part is integrally connected to the hollow cylindrical part. When the cap is fed on the feed conveyor belt, the top wall of the feed inlet pushes the cap so that the cap is in a flat position. The discharge end of the feed conveyor belt is provided with an inclined slide, and the bottom end of the inclined slide is provided with a first vertical channel. The flat cap slides down along the inclined slide and the first vertical channel.

[0007] The bottom end of the first vertical channel is provided with a first receiving conveyor belt, and the bottom end of the first receiving conveyor belt is provided with a second receiving conveyor belt. When the hollow cylindrical part of the plug reaches the first receiving conveyor belt, it is discharged laterally along the first receiving conveyor belt. When the hollow conical part of the plug reaches the first receiving conveyor belt, it turns and falls onto the second receiving conveyor belt along the end of the first receiving conveyor belt, so that the hollow cylindrical part of the plug reaches the second receiving conveyor belt and is discharged laterally along the second receiving conveyor belt. When the tube hole intermittently rotates to the capping position, the plug that is discharged laterally is pressed downward into the opening of the rigid tube.

[0008] When the pipe tunnel is intermittently rotated to the lower pipe position, the sealed hard pipe discharges material along the lower pipe position.

[0009] Preferably, the discharge end of the first receiving conveyor belt is provided with a second vertical channel, the discharge end of the second receiving conveyor belt is provided with a third vertical channel, the bottom ends of the second and third vertical channels are provided with discharge conveyor belts, the side ends of the discharge conveyor belts are provided with discharge push cylinders, the outer side of the capping mechanism is provided with a capping slide, one end of the capping slide is provided with a hole above the capping position, and a capping push cylinder is provided on the capping slide above the hole. When the cap is discharged laterally with the discharge conveyor belt, the cap is pushed out laterally by the discharge push cylinder so that the cap slides along the capping slide to the hole, and is pushed down by the capping push cylinder to press the cap into the opening of the rigid pipe.

[0010] Preferably, the second vertical channel is located on the adjacent side of the third vertical channel. Both the second and third vertical channels include a vertical tube section and an inclined tube section integrally connected to the bottom end of the vertical tube section. A rod frame is provided between the bottom ends of the inclined tube sections of the second and third vertical channels. A movable rod is rotatably connected to the rod frame. The movable rod rotates parallel to the plane of the opening end of the inclined tube section. One end of the movable rod is located at the opening at the bottom end of the inclined tube section of the second vertical channel, and the other end is located at the bottom end of the inclined tube section of the third vertical channel. An inner rod parallel to the length direction of the inclined tube section is connected to it. A through groove is provided on the inclined tube section of the third vertical channel. When the plug slides down along the inclined tube section of the second vertical channel, it pushes one end of the movable rod, causing the movable rod to rotate, so that the inner rod is inserted into the inclined tube section of the third vertical channel along the through groove to block the plug in the inclined tube section of the third vertical channel.

[0011] Preferably, a baffle is provided on one side of the end of the discharge conveyor belt, the discharge push cylinder is fixed to the top of the baffle, a baffle is connected to the baffle, the baffle is located on the end of the discharge conveyor belt, when the plug is discharged laterally with the discharge conveyor belt, it abuts against one side of the baffle and is pushed out laterally by the discharge push cylinder.

[0012] Preferably, the movable end of the discharge pusher cylinder is designed to fit the outer wall of the hollow cylindrical part of the plug, and the end of the discharge slide near the discharge conveyor belt is designed to gradually open.

[0013] Preferably, the inclined slide includes an upper slide connected to the discharge end of the feeding conveyor belt and a bottom slide connected to the bottom end of the upper slide. The inclined slide is composed of slide rods arranged opposite to each other. The two slide rods of the upper slide are arranged in parallel, and the two slide rods of the bottom slide are gradually opened from top to bottom. When the plug in the flat state slides down the inclined slide, it slides down to the bottom end of the bottom slide and falls through the opening between the slide rods.

[0014] Preferably, a filling pusher cylinder is provided at the filling position, and a sealing plate is connected to the movable end of the filling pusher cylinder. A fixed tube is vertically inserted through the sealing plate, and the top end of the fixed tube is connected to the discharge pipe. The filling pusher cylinder extends downward, driving the bottom end of the fixed tube to be inserted into the opening of the rigid pipe. The sealing plate covers the opening of the rigid pipe, and the material is filled into the rigid pipe through the discharge pipe.

[0015] Preferably, each pipe hole has an opening at its bottom end, and a lower pipe pusher cylinder is provided on the machine platform below the lower pipe position. A lower pipe slide is provided on one side of the lower pipe position. The lower pipe pusher cylinder extends upward, and the movable end of the lower pipe pusher cylinder pushes the hard pipe upward along the opening. The pushed hard pipe is discharged along the lower pipe slide.

[0016] Preferably, a detection position is provided between the upper tube position and the filling position. The detection position includes a detection frame erected on the machine platform, and a detection sensor is connected to the top of the detection frame for detecting the rigid tube on the tube hole.

[0017] The present invention also provides an automatic adhesive filling method, comprising the following steps:

[0018] The machine platform is equipped with upper pipe position, filling position, capping position and lower pipe position at each pipe hole. The turntable rotates intermittently, and when each pipe hole is rotated to the upper pipe position, the hard pipe is inserted into the pipe hole with the opening of the hard pipe facing upward. When the pipe hole rotates intermittently to the filling position, the material is poured into the hard pipe through the discharge pipe. There is a capping mechanism on one side of the machine platform. When the pipe hole rotates intermittently to the capping position, the capping mechanism seals the opening of the hard pipe. When the pipe hole rotates intermittently to the lower pipe position, the capped hard pipe is discharged along the lower pipe position.

[0019] When the plug is in a side-standing position on the feeding conveyor belt, it is pushed by the top wall of the feed inlet to make it lie flat. The flat plug slides down along the inclined slide and the first vertical channel. If the hollow cylindrical part of the plug lands on the first receiving conveyor belt, it is discharged laterally with the first receiving conveyor belt. If the hollow conical part of the plug lands on the first receiving conveyor belt, the plug flips backward and falls to the end of the first receiving conveyor belt onto the second receiving conveyor belt, so that the hollow cylindrical part of the plug lands on the second receiving conveyor belt and is discharged laterally with the second receiving conveyor belt. This achieves the goal of discharging the plug in a flat position in the same direction. The plug that is discharged laterally is pressed down into the opening of the rigid pipe.

[0020] The beneficial effects of this invention are as follows: When the rigid tube is intermittently rotated to the upper tube position, filling position, capping position, and lower tube position via a turntable, the upper tube, filling, capping, and lower tube processes are performed during the intermittent intervals. Specifically, when the cap is in a side-standing position on the feeding conveyor belt, the top wall of the feeding port pushes the cap to a flat position. The flat cap slides down along the inclined slide and the first vertical channel. If the hollow cylindrical part of the cap lands on the first receiving conveyor belt, it is carried by the first receiving conveyor belt... The conveyor belt discharges material laterally. If the hollow cone of the cap lands on the first receiving conveyor belt, the cap flips backward and falls along the end of the first receiving conveyor belt onto the second receiving conveyor belt, so that the hollow cylinder of the cap lands on the second receiving conveyor belt and discharges material laterally with the second receiving conveyor belt. This achieves the goal of discharging the caps in a flat position in the same direction. The laterally discharged caps are pressed downward into the opening of the rigid tube, which solves the problem of low capping efficiency in the existing automatic adhesive filling process.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0041] like Figure 1 , Figure 5 , Figure 7 , Figure 8As shown, an automatic adhesive filling device includes a machine base 1. A material tank is provided on one side of the machine base 1 for holding paste-like adhesive material. A discharge pipe 2 is connected to the material tank. A turntable 4 is provided on the machine base 1 for holding rigid tubes 3. Material is poured into the rigid tubes 3 through the discharge pipe 2. The turntable 4 is rotatably connected to the machine base 1. Multiple tube holes 41 are spaced apart around the circumference of the turntable 4. One end of the rigid tube 3 is open. At each tube hole 41, the machine base 1 has an upper tube position, a filling position, a capping position, and a lower tube position. When the machine rotates intermittently, causing each pipe hole 41 to rotate sequentially to the upper pipe position, the rigid pipe 3 is inserted into the pipe hole 41 with its opening facing upwards. When the pipe hole 41 rotates intermittently to the filling position, material is poured into the rigid pipe 3 through the discharge pipe 2. A capping mechanism 5 is provided on one side of the machine base 1, and a feed inlet 51 is opened on one side of the capping mechanism 5. A feed conveyor belt 6 passes through the feed inlet 51 to convey the cap 7 into the capping mechanism 5. The cap 7 includes a hollow cylindrical part 71 and a hollow conical part 72. The open end of the hollow conical part 72 is connected to the hollow cylindrical part 71. In the integrated connection, when the plug 7 is fed onto the feeding conveyor belt 6 while standing upright, the top wall of the inlet 51 pushes the plug 7 to make it lie flat. The discharge end of the feeding conveyor belt 6 is provided with an inclined slide 8, and the bottom end of the inclined slide 8 is provided with a first vertical channel 9. The flat plug 7 slides down along the inclined slide 8 and the first vertical channel 9. The bottom end of the first vertical channel 9 is provided with a first receiving conveyor belt 10, and the bottom end of the first receiving conveyor belt 10 is provided with a second receiving conveyor belt 11. The hollow cylindrical part 71 of the plug 7 falls onto the first receiving conveyor belt. When the first receiving conveyor belt 10 discharges material laterally, the hollow conical part 72 of the plug 7 falls onto the first receiving conveyor belt 10 and then turns along the end of the first receiving conveyor belt 10 to fall onto the second receiving conveyor belt 11, so that the hollow cylindrical part 71 of the plug 7 falls onto the second receiving conveyor belt 11 and discharges material laterally with the second receiving conveyor belt 11. When the pipe hole 41 intermittently rotates to the capping position, the plug 7 that is discharged laterally is pressed down into the opening of the hard pipe 3. When the pipe hole 41 intermittently rotates to the lower pipe position, the capped hard pipe 3 discharges material along the lower pipe position.

[0042] This invention is based on an existing adhesive filling machine, including a machine base 1. A material tank is located on one side of the machine base 1 for holding paste-like adhesive materials. A discharge pipe 2 is connected to the material tank. A turntable 4 is provided on the machine base 1 for holding rigid tubes 3. Specifically, a hydraulic cylinder is located at the top of the material tank, and the bottom end of the hydraulic cylinder is connected to a piston plate inside the material tank. The piston plate is pushed downwards by the movable end of the hydraulic cylinder, squeezing the material inside the material tank, causing the discharge pipe 2 to discharge material outwards under high pressure. A conventional on / off valve is provided at one end of the discharge pipe 2 to control the opening and closing of the discharge pipe 2 and to fill the rigid tube 3 with material. In this invention, the turntable 4 is rotatably connected to the machine base 1. Multiple tube holes 41 are spaced apart around the circumference of the turntable 4. One end of the rigid tube 3 is open, meaning the head of the rigid tube 3 is sealed. The bottom remains open, with the opening facing upwards. On the machine base 1, there are upper pipe positions, filling positions, capping positions, and lower pipe positions at each pipe hole 41. The turntable 4 rotates intermittently, causing each pipe hole 41 to rotate sequentially to the upper pipe position. When the hard pipe 3 is inserted into the pipe hole 41, the opening of the hard pipe 3 faces upwards. When the pipe hole 41 rotates intermittently to the filling position, material is poured into the hard pipe 3 through the discharge pipe 2. A capping mechanism 5 is provided on one side of the machine base 1. When the pipe hole 41 rotates intermittently to the capping position, the opening of the hard pipe 3 is capped and sealed by the capping mechanism 5. When the pipe hole 41 rotates intermittently to the lower pipe position, the capped hard pipe 3 is discharged along the lower pipe position. That is, when the hard pipe 3 rotates intermittently with the turntable 4 to the upper pipe position, filling position, capping position, and lower pipe position, the upper pipe, filling, capping, and lower pipe processing are carried out during the intermittent interval time.

[0043] Specifically, a feed inlet 51 is provided on one side of the capping mechanism 5, and a feed conveyor belt 6 passes through the feed inlet 51 to convey caps 7 into the capping mechanism 5. The cap 7 includes a hollow cylindrical part 71 and a hollow conical part 72. The open end of the hollow conical part 72 is integrally connected to the hollow cylindrical part 71. The caps 7 on the feed conveyor belt 6 are conveyed one by one, but the caps 7 that are conveyed may be in a flat position with the opening facing upward, a flat position with the opening facing downward, or a side-standing position with the opening facing outward. When the cap 7 is in a side-standing position on the feed conveyor belt 6, because the cap 7 has a flat overall design, the side-standing cap 7 has the highest height and passes through the feed inlet 51. The top wall pushes the stopper 7 to make it lie flat. If the side end of the hollow cylindrical part 71 abuts the top wall of the feed inlet 51, considering that the stopper 7 is not often in a side-standing position, if it is found manually that the stopper 7 has not been fed for a long time, the stopper 7 can be manually straightened to make it lie flat for feeding. Alternatively, a detection push rod can be provided at the feed inlet 51. When the existing detection components such as photoelectric sensors and pressure sensors located at the top wall of the feed inlet 51 detect the stopper 7 abutting at the feed inlet 51, the detection push rod is triggered to push the stopper 7 outward to avoid blocking the material. In addition, multiple transverse rollers can be arranged at the top wall of the feed inlet 51, such as... Figure 9 As shown, the roller rotates axially, which helps the stopper 7 to turn until the stopper 7 is in a flat position and feeds through the feed inlet 51;

[0044] The discharge end of the feeding conveyor belt 6 is equipped with an inclined slide 8. The bottom end of the inclined slide 8 is equipped with a first vertical channel 9. The plug 7, lying flat, slides down along the inclined slide 8 and the first vertical channel 9. The bottom end of the first vertical channel 9 is equipped with a first receiving conveyor belt 10, and the bottom end of the first receiving conveyor belt 10 is equipped with a second receiving conveyor belt 11. Specifically, the end of the first receiving conveyor belt 10 is located directly below the first vertical channel 9, and the second receiving conveyor belt 11 is arranged parallel to the bottom of the first receiving conveyor belt 10. The plug 7, lying flat, slides down along the first vertical channel 9. If the hollow cylindrical portion 71 of the plug 7 falls onto the first receiving conveyor belt 10, as... Figure 11 As shown, most of the hollow cylindrical portion 71 contacts the first receiving conveyor belt 10 and is discharged laterally along with the first receiving conveyor belt 10. If the hollow conical portion 72 of the plug 7 falls onto the first receiving conveyor belt 10, as... Figure 12 As shown, this corresponds to the tip of the plug 7 contacting the first receiving conveyor belt 10. Under the forward conveying force of the first receiving conveyor belt 10, the plug 7 flips backward, as... Figure 13 , Figure 14 , Figure 15 As shown, the material is transferred from the end roller of the first receiving conveyor belt 10 to the second receiving conveyor belt 11, so that the hollow cylindrical part 71 of the plug 7 falls onto the second receiving conveyor belt 11 and is discharged laterally with the second receiving conveyor belt 11, thereby achieving the discharge of the plug 7 in a flat position in the same direction. When the tube hole 41 intermittently rotates to the capping position, as... Figure 4 As shown, the horizontally discharging cap 7 is pressed downward into the opening of the rigid tube 3, which solves the problem of low capping efficiency in the existing automatic adhesive filling process.

[0045] In embodiments of the present invention, such as Figure 1 , Figure 7 , Figure 8As shown, the discharge end of the first receiving conveyor belt 10 is provided with a second vertical channel 12, and the discharge end of the second receiving conveyor belt 11 is provided with a third vertical channel 13. The bottom ends of the second vertical channel 12 and the third vertical channel 13 are provided with a discharge conveyor belt 14. The side end of the discharge conveyor belt 14 is provided with a discharge pusher cylinder 15. The outer side of the capping mechanism 5 is provided with a capping slide 16, which is fixedly connected to the outer side of the capping mechanism 5. One end of the capping slide 16 is located above the capping position and has an opening... A cap-pressing cylinder 17 is fixedly installed above the drain hole 161 on the cap-discharge slide 16. Specifically, a baffle 18 is provided on one side of the end of the discharge conveyor belt 14, and the discharge cylinder 15 is fixed to the top of the baffle 18. A baffle 19 is connected to the baffle 18 and is located at the end of the discharge conveyor belt 14. The movable end of the discharge cylinder 15 is designed to fit against the outer wall of the hollow cylindrical part 71 of the cap 7. The cap-discharge slide 16 is close to the discharge conveyor belt. One end of the conveyor belt 14 is designed to gradually open, so that when the cap 7 is discharged laterally along the discharge conveyor belt 14, it abuts against the side of the baffle 19. When the filled rigid tube 3 is intermittently rotated to the capping position along the tube hole 41, the cap 7 is pushed out laterally by the discharge push cylinder 15, so that the cap 7 slides along the cap discharge slide 16 to the drain hole 161. The cap 7 leaks down along the drain hole 161 into the rigid tube 3 at the capping position, and is then pushed down by the capping push cylinder 17 to press the cap 7 into the opening of the rigid tube 3. After capping, the capping push cylinder 17 and the discharge push cylinder 15 return to their original positions. The plug 7 on the discharge conveyor belt 14 is conveyed laterally and continues to abut against the baffle 19, waiting for the next capping action. The movable end of the discharge push cylinder 15 is designed to fit against the outer wall of the hollow cylindrical part 71 of the plug 7. The end of the plug slide 16 near the discharge conveyor belt 14 is designed to gradually open, which facilitates the plug 7 pushed towards the plug slide 16 to gradually be aligned and be capped accurately and efficiently.

[0046] In embodiments of the present invention, such as Figure 1 , Figure 7 , Figure 8 As shown, the second vertical channel 12 is located on the adjacent side of the third vertical channel 13. Both the second vertical channel 12 and the third vertical channel 13 include a vertical tube section and an inclined tube section integrally connected to the bottom end of the vertical tube section. Since the plugs 7 on the first receiving conveyor belt 10 and the second receiving conveyor belt 11 are in a flat position with the opening facing down, the plugs 7 fall into the second vertical channel 12 and the third vertical channel 13, and are in a side-standing position. Finally, they slide down along the inclined tube section onto the discharge conveyor belt 14. Due to the lateral conveying action of the discharge conveyor belt 14, the plugs 7 discharged on the discharge conveyor belt 14 are in a flat position with the opening facing up, which facilitates the discharge and capping.

[0047] In particular, to avoid mutual interference when adjacent inclined tube sections are being fed, such as Figure 1 , Figure 7 , Figure 8 , Figure 16 , Figure 17 As shown, a rod frame 20 is provided between the bottom ends of the inclined tube sections of the second vertical channel 12 and the third vertical channel 13. The rod frame 20 can be fixed to the tube wall of the adjacent inclined tube section. A movable rod 21 is rotatably connected to the rod frame 20. The movable rod 21 rotates parallel to the plane of the opening end of the inclined tube section. One end of the movable rod 21 is located at the opening of the bottom end of the inclined tube section of the second vertical channel 12, and the other end is located at the bottom end of the inclined tube section of the third vertical channel 13, and is connected to an inner rod 22 parallel to the length direction of the inclined tube section. A through groove 131 is opened on the inclined tube section of the third vertical channel 13 to allow the inner rod 22 to pass through. Figure 16 As shown, the portion of the movable rod 21 located at the bottom opening of the inclined tube section of the second vertical channel 12 is designed as a straight rod, while the portion of the movable rod 21 located at the bottom of the inclined tube section of the third vertical channel 13 is designed as a bent rod. Figure 16 The inner rod 22 is perpendicular to the end of the bent rod, that is, parallel to the length direction of the inclined tube.

[0048] In the initial state, such as Figure 16 As shown, the inner rod 22 is not fully inserted into the inclined tube section, which will not affect the material feeding. When the plug 7 slides down along the inclined tube section of the second vertical channel 12, the outer end of its hollow cylindrical part 71 pushes one end of the movable rod 21, causing the movable rod 21 to rotate, so that the inner rod 22 is inserted into the inclined tube section of the third vertical channel 13 along the through groove 131, as shown. Figure 17 As shown, the plug 7 in the inclined tube section of the third vertical channel 13 is used to block the plug 7 in the inclined tube section of the second vertical channel 12 until the plug 7 in the inclined tube section of the second vertical channel 12 completely slides off and moves away from the movable rod 21. Then the movable rod 21 rotates back to its original position, and the plug 7 in the inclined tube section of the third vertical channel 13 will slide off. Specifically, a torsion spring or other elastic component can also be provided at the rotating connection of the movable rod 21 to facilitate the rotation and reset of the movable rod 21. If the plug 7 slides off along the inclined tube section of the second vertical channel 12, the inner rod 22 cannot be inserted into the through groove 131, indicating that there is a plug 7 sliding off in the inclined tube section of the third vertical channel 13 at this time. Then the plug 7 in the inclined tube section of the second vertical channel 12 will only start to slide off after the plug 7 in the inclined tube section of the third vertical channel 13 completely slides off. That is, the adjacent inclined tube sections do not interfere with each other when feeding.

[0049] In embodiments of the present invention, such as Figure 1 , Figure 7 , Figure 8 , Figure 10As shown, the inclined slide 8 includes an upper slide 81 connected to the discharge end of the feed conveyor belt 6 and a lower slide 82 connected to the bottom end of the upper slide 81. The inclined slide 8 is composed of slide rods 80 arranged opposite each other. The two slide rods 80 of the upper slide 81 are arranged in parallel, and the two slide rods 80 of the lower slide 82 are arranged to gradually open from top to bottom. When the plug 7 in a flat state slides down the inclined slide, regardless of whether the opening of the plug 7 is facing up or down, the two slide rods 80 of the upper slide 81... The gap between them is smaller than the outer diameter of the hollow cylindrical part 71. As a result, the plug 7 is supported by the side walls of the inclined slide 8 and the slide rod 80. The plug 7 slides down quickly along the inclined slide 8, and the position of the plug 7 remains unchanged until it slides to the bottom end of the bottom slide 82. Since the opening size of the slide rods 80 on both sides of the bottom slide 82 is larger than the outer diameter of the hollow cylindrical part 71, the plug 7 slides down through the opening between the slide rods 80 and falls into the first vertical channel 9, and the position of the plug 7 remains unchanged.

[0050] In embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, a filling pusher cylinder 23 is provided at the filling position. The filling pusher cylinder 23 is fixedly mounted on the machine base 1. A sealing plate 24 is fixedly connected to the movable end of the filling pusher cylinder 23 via a connecting rod. A fixed tube 25 is vertically inserted through the sealing plate 24. The top end of the fixed tube 25 is connected to the discharge pipe 2 and extends downward through the filling pusher cylinder 23, as shown. Figure 3 As shown, the bottom end of the fixed tube 25 is inserted into the opening of the rigid tube 3, and the sealing plate 24 covers the opening of the rigid tube 3. Material is then poured into the rigid tube 3 through the discharge pipe 2. After filling, as shown... Figure 2 As shown, the filling pusher cylinder 23 drives the fixed tube 25 and the sealing plate 24 to move up to the top of the rigid tube 3, without affecting the rotation of the rigid tube 3 with the turntable 4.

[0051] In embodiments of the present invention, such as Figure 1 , Figure 5 , Figure 6 As shown, each pipe hole 41 has a through-hole 42 at its bottom end. The size of the through-hole 42 is naturally smaller than the outer diameter of the rigid pipe 3 to prevent the rigid pipe 3 from falling off. A lower pipe pusher 26 is provided on the machine base 1 below the lower pipe position. The lower pipe pusher 26 can be fixedly installed inside the machine base 1. The movable end of the lower pipe pusher 26 extends upward. A lower pipe slide 27 is provided on one side of the lower pipe position. When the filled rigid pipe 3 rotates to the lower pipe position with the turntable 4, it extends upward through the lower pipe pusher 26. The movable end of the lower pipe pusher 26 pushes the rigid pipe 3 upward along the through-hole 42. The pushed-out rigid pipe 3 is discharged along the lower pipe slide 27. Specifically, the lower pipe slide 27 is located outside the lower pipe position. This can be achieved by setting the position of the movable end of the lower pipe pusher 26 to be located at a position off the center of gravity at the head end of the rigid pipe 3. Figure 6As shown, the ejected rigid tube 3 falls outwards onto the lower tube slide 27 for discharge. After discharge, the movable end of the lower tube push cylinder 26 retracts and resets, and is located below the tube hole 41, without affecting the rotation of the turntable 4.

[0052] In embodiments of the present invention, such as Figure 1 As shown, a detection position is provided between the upper tube position and the filling position. The detection position includes a detection frame 28 erected on the machine base 1. A detection sensor 29 is connected to the top of the detection frame 28. The detection sensor 29 uses existing detection components such as photoelectric sensors to detect the hard tube 3 on the tube hole 41. Since the open end of the hard tube 3 is higher than the tube hole 41, if the detection sensor 29 of the detection position does not detect the hard tube 3, it means that the hard tube 3 is missing from the tube hole 41. Therefore, when the tube hole 41 is controlled to rotate to the filling position, the capping position, and the lower tube position, the filling, capping, and lower tube actions are not performed.

[0053] The upper pipe position is also equipped with an upper pipe conveyor belt 30. Since the hard pipe 3 generally needs to be sealed at the head end, when the pre-treated hard pipe 3 is conveyed to the upper pipe position in an orderly manner along the upper pipe conveyor belt 30, the opening direction is consistent. Since the hard pipe 3 has a regular shape and appropriate size, it can be manually picked up one by one and inserted into the pipe hole 41. Alternatively, the existing material picking robot arm can be used to grab and load the material. Specifically, the clamping arm is used to clamp the hard pipe 3 horizontally, and then it is turned and moved horizontally to the upper pipe position above the pipe hole 41, and then inserted downwards.

[0054] The present invention also provides an automatic adhesive filling method, comprising the following steps:

[0055] The machine 1 has an upper pipe position, a filling position, a capping position and a lower pipe position at each pipe hole 41. The turntable 4 rotates intermittently, and when each pipe hole 41 is rotated to the upper pipe position, the hard pipe 3 is inserted into the pipe hole 41 with the opening of the hard pipe 3 facing upward. When the pipe hole 41 is rotated to the filling position, the material is poured into the hard pipe 3 through the discharge pipe 2. A capping mechanism 5 is provided on one side of the machine 1. When the pipe hole 41 is rotated to the capping position, the opening of the hard pipe 3 is capped and sealed by the capping mechanism 5. When the pipe hole 41 is rotated to the lower pipe position, the capped hard pipe 3 is discharged along the lower pipe position.

[0056] When the cap 7 is in a side-standing position on the feeding conveyor belt 6, it is pushed by the top wall of the feeding port 51 to make the cap 7 lie flat. The flat cap 7 slides down along the inclined slide 8 and the first vertical channel 9. If the hollow cylindrical part 71 of the cap 7 falls onto the first receiving conveyor belt 10, it will be discharged laterally with the first receiving conveyor belt 10. If the hollow conical part 72 of the cap 7 falls onto the first receiving conveyor belt 10, the cap 7 flips backward and falls along the end of the first receiving conveyor belt 10 onto the second receiving conveyor belt 11, so that the hollow cylindrical part 71 of the cap 7 falls onto the second receiving conveyor belt 11 and is discharged laterally with the second receiving conveyor belt 11. Thus, the caps 7 are all discharged in a flat position in the same direction. The horizontally discharged caps 7 are pressed downward into the opening of the rigid tube 3, which solves the problem of low capping efficiency in the existing automatic adhesive filling process.
