Description

Technical Field

[0002] In modern manufacturing, with the continuous expansion of production scale and the increasing processing accuracy, the traditional manual feeding operation has gradually revealed its limitations. This operation mode is not only inefficient, but also prone to operating errors due to manual fatigue, which in turn affects product quality and production efficiency. Therefore, seeking an efficient, fast and stable automatic feeding solution has become an important direction for the transformation and upgrading of the manufacturing industry, and automatic feeders have come into being.

[0003] Automatic feeders use automation technology to realize intelligent and precise material supply, thereby reducing dependence on manual operation and effectively reducing the risk of human error. However, with the continuous development of industrial automation, enterprises have higher and higher requirements for production efficiency, accuracy and cost control. For some parts with specific structures, such as plungers, in order to improve the efficiency of the production line, the products conveyed by the automatic feeder need to be used directly in the next process according to the feeding posture. Therefore, the raw materials conveyed by the automatic feeder are required to be arranged according to a certain placement posture, that is, the raw material conveying posture is required to have strict consistency, and then through the coordinated work with other automated equipment, the entire production line can be automated. The automatic feeder in the existing technology can generally only realize on-time and quantitative delivery. The problem of product consistency is mainly solved through manual intervention.

[0039] The present application provides a plunger pipeline automatic feeder, such as Figure 1 As shown, the plunger 10 is used for automatic feeding. The plunger 10 is cylindrical and has a first end 101 and a second end 102 relative to each other. It can be understood that since the main purpose of this application is to adjust the conveying posture of the plunger 10, the first end 101 and the second end 102 are not two ends with the same structure.

[0040] like Figures 2~4 As shown, the plunger-pipe automatic feeder includes a feeding trough 20 , a plunger vibration plate 30 , a conveyor belt assembly 40 , a material dropping assembly 50 , a material trough 60 , a material pushing assembly 70 , a material dropping assembly 80 and a feeding pipeline 90 .

[0041] The main purpose of this application is to realize feeding with a uniform conveying posture for disordered plungers 10, and its main structural components are a conveyor belt assembly 40 and a blanking assembly 50. Therefore, this patent starts with the structure of the conveyor belt assembly 40 and the blanking assembly 50.

[0042] The conveyor belt assembly 40 is used to convey the plunger 10 along a first direction, and the axial direction of the plunger conveyed by the conveyor belt assembly 40 is consistent with the first direction, that is, the plunger 10 is transversely arranged on the conveyor belt assembly 40 .

[0043] The blanking assembly 50 is disposed close to the discharge end 402 of the conveyor belt assembly 40 , and the blanking assembly 50 includes a blanking reversing block 51 , a blanking pushing block 52 and a blanking driving member 53 .

[0044] Specifically, the material-blanking reversing block 51 is arranged on one side of the conveyor belt assembly 40, and the material-blanking reversing block 51 is formed with a reversing channel 510 which passes through from top to bottom. The upper end of the reversing channel 510 is a reversing inlet 511, and the reversing inlet 511 has a front edge 512 close to the incoming end 401 of the conveyor belt assembly 40 and a rear edge 513 opposite to the front edge 511; the lower end of the reversing channel 510 is a reversing outlet 514, and the reversing outlet 514 is configured to only allow the plunger 10 to pass through with one end facing downward, that is, the size of the reversing outlet 514 only allows the plunger 10 to pass vertically.

[0045] Among them, the blanking push block 52 is formed with a feed channel 520, the lower end of the feed channel 520 is open and faces the incoming end 401 of the conveyor belt assembly 40 to form a first feed port 521, and the first feed port 521 is suitable for the two ends of the plunger 10 to pass through; the blanking push block 52 is slidably arranged and has a feeding position and a blanking position on the sliding stroke. When the blanking push block 52 is in the feeding position, the feed channel 520 corresponds to the conveyor belt assembly 40, and when the blanking push block 52 is in the blanking position, the feed channel 520 corresponds to the reversing channel 510; the blanking drive member 53 is used to drive the blanking push block 52 to slide. Specifically, the blanking drive member 53 can be an electric push rod, a cylinder or a hydraulic cylinder. It can be understood that in the embodiments of the present application, other parts where the cylinder appears can also be replaced by electric push rods or hydraulic cylinders.

[0046] That is, when the blanking cylinder pushes the blanking push block 52 from the feeding position to the blanking position, the plunger 10 inside the feeding channel 520 can be pushed from the conveyor belt assembly 40 to the top of the reversing channel 510. At this time, the plunger 10 falls into the reversing channel 510 under the action of gravity and falls out from the reversing outlet 514 in a vertical posture.

[0047] Since the orientation of the incoming plunger 10 of the conveyor belt assembly is uncertain, the first end 101 may be in front, or the second end 102 may be in front. Therefore, in order to ensure that the first end 101 is always facing upward when the plunger 10 falls, a material selection groove 522 is formed at the end of the feed channel 520. The material selection groove 522 is configured to match the first end 101 and prevent the second end 102 from entering. For example, in one embodiment, the first end 101 is a hemispherical structure and the second end is a cylindrical structure. Then, the material selection groove 522 can be designed as a hemispherical groove body that matches the hemispherical structure, so that the first end 101 of the hemispherical structure can enter, but the cylindrical second end 102 cannot enter.

[0048] Among them, the slot of the blanking selection groove 522 is located between the front edge 512 and the rear edge 513 in the first direction and is arranged close to the rear edge 513. In addition, the distance D between the slot and the front edge 512 in the first direction, the length L of the plunger 10, and the depth H of the blanking selection groove 522 satisfy the following relationship: LH<D<L.

[0049] According to the above relationship, it can be known that when the blanking push block 52 is in the blanking position, if the first end 101 faces forward, the first end 101 enters the blanking selection groove 522. Since LH<D, the second end 101 is located between the front edge 512 and the rear edge 513 at this time. The blanking selection groove 522 will prevent the first end 101 from falling, so the plunger will fall into the reversing channel 510 with the second end 102 facing downward, and fall out from the reversing outlet 514 in a vertical posture with the second end 102 facing downward.

[0050] On the contrary, if the second end 102 faces forward, the second end 102 cannot enter the material selection groove 522. Since D<L, at this time, the second end 101 is located between the front edge 512 and the rear edge 513, and the first end is located at the upper end of the front edge 512. The front edge 512 will prevent the first end 101 from falling, so the plunger will also fall into the reversing channel 510 with the second end 102 facing downward, and fall out from the reversing outlet 514 in a vertical posture with the second end 102 facing downward.

[0051] The above structural design ensures that no matter what the orientation of the plunger 10 of the conveyor belt assembly 40 is, the plunger 10 will fall with the second end 102 facing downward when passing through the reversing outlet 514, thereby ensuring the consistency of the feeding posture of the plunger 10, and then realizing the automated operation of the entire production line by working in coordination with other automated equipment.

[0052] In an embodiment of the present application, the material selection groove 522 can be directly formed on the material pushing block 52, but for the scenario where the internal structure of the material selection groove 522 is more complex, its processing will be difficult. Therefore, the material selection groove 522 can also be formed on other structures that cooperate with the material pushing block 52.

[0053] As in a preferred embodiment, the blanking assembly 50 also includes a blanking insert 53, and a receiving groove matched with the blanking insert 53 is formed on the blanking push block 52. The blanking insert 53 is fixed to the receiving groove, and the blanking selection groove 522 is formed on the blanking insert 53. The advantage of such a design is that the internal shape of the blanking selection groove 522 can be designed more finely to ensure that the blanking selection groove 522 strictly meets the characteristics of matching the first end 101 and preventing the second end 102 from entering, thereby achieving the effect of unifying the feeding posture of the plunger 10.

[0054] In an embodiment of the present application, the conveyor belt assembly 40 includes a conveyor belt 41, a conveyor belt motor 42, a conveyor belt cover plate 43, a conveyor belt support plate 44, a motor support plate 45, a conveyor belt material sensor 46, a material stop sensor 47, a front material stop unit 48 and a rear material stop unit 49.

[0055] Among them, the conveyor belt 41 is arranged along the first direction, and the conveyor belt 41 is preferably two parallel flat belts. The plunger 10 is placed between the two belts during transportation. The conveyor belt cover plate 43 is arranged on both sides of the conveyor belt 41 to prevent the plunger 10 from falling during transportation. The conveyor belt support plate 44 is connected to the conveyor belt cover plate 43, the motor support plate 45 is connected to the conveyor belt cover plate 43, and the conveyor belt motor 42 is installed on the motor support plate 45 and is connected to the conveyor belt 41 drive. The drive link can be a direct connection or an indirect connection through a synchronous belt. In this embodiment, an indirect connection with a synchronous belt is adopted.

[0056] The conveyor belt loading sensor 46 and the material stopping sensor 47 are sequentially arranged above the conveyor belt 41 along the first direction, and the front material stopping unit 48 and the rear material stopping unit 49 are sequentially arranged at the portion of the conveyor belt 41 close to the discharge end 402 along the first direction.

[0057] The conveyor belt material sensor 46 can sense the plunger 10 on the conveyor belt 41, thereby providing a signal basis for the subsequent operation of the blanking cylinder. The front stop unit 48 and the rear stop unit 49 adopt a design that combines a cylinder and a baffle, and are equipped with a stop sensor to prevent the plunger 10 from continuing to convey when the blanking cylinder is working.

[0058] In order to ensure that when the plunger 10 enters the feed channel 520 , the upper end of the blanking push block 52 has a blanking sensing hole 523 connected to the feed channel 520 , and a blanking sensor 54 is installed above the blanking sensing hole 523 .

[0059] It is understandable that in order to realize full process automation, all sensors and cylinder starts involved in this application need to be connected to a control system, which can be an electric control cabinet equipped with PLC or a central control computer in a production workshop.

[0060] After the connection is completed, the conveyor belt assembly 40 and the blanking assembly 50 can be connected to the automatic feeding process to realize automatic feeding.

[0061] In a preferred embodiment of the present application, the plunger pipeline automatic feeder is connected to the feeding trough 20 and the plunger vibration plate 30 at the front end of the conveyor belt assembly 40 and the blanking assembly 50 to achieve continuous feeding of the conveyor belt 41.

[0062] Among them, the upper end of the plunger vibration disk 30 has a feed trough 300, and the discharge port of the plunger vibration disk 30 is connected to the incoming end 401 of the conveyor belt assembly 40, that is, the messy plunger material is in the plunger vibration disk 30 and then fed to the conveyor belt 41 in sequence through its discharge port.

[0063] Preferably, a vibration plate sensor is installed on the side of the feed trough 300 to sense whether there is any residual material in the feed trough 300. When the residual material in the feed trough 300 is insufficient, the feed trough 20 starts to feed material into the feed trough 300.

[0064] The feeding trough 20 includes a shell 21, a feeding belt 22 and a feeding drive 23. A feeding port 211 is formed at the upper end of the shell 21 and a feeding cavity 210 is provided inside. The feeding belt 22 is obliquely arranged at the bottom of the feeding cavity 210. The feeding drive 23 is used to drive the feeding belt 22 to rotate and feed. The feeding drive 23 can use a servo motor or a stepper motor to realize the rotation of the feeding belt 22. In the present embodiment, the feeding drive 23 uses a feeding cylinder and a one-way bearing to realize the one-way rotation of the feeding belt 22.

[0065] The feeding port 211 is arranged at the lower end of the feeding belt 22 , and a vertically arranged feeding outlet pipe 212 is formed at the higher end of the shell 21 corresponding to the feeding belt 22 , and the lower end of the feeding outlet pipe 212 is arranged toward the feeding trough 300 .

[0066] Correspondingly, the plunger pipeline automatic feeder is connected to the material trough 60, the material pushing assembly 70, the material unloading assembly 80 and the feeding pipeline 90 at the rear ends of the conveyor belt assembly 40 and the material dropping assembly 50.

[0067] Among them, the upper end of the material trough 60 is open and its loading end 601 is arranged below the blanking reversing block 51, the pushing assembly 70 is used to push the plunger 10 in the material trough 60 to move toward the unloading end 602 of the material trough 60, the unloading assembly 80 and the feeding pipe 90 are both arranged at the unloading end 6020 of the material trough 60, and the unloading assembly 80 is used to unload the plunger 10 located at the unloading end 602 to the feeding pipe 90.

[0068] Specifically, a blanking guide 61 is installed at the feeding end 601 of the material trough 60, and a blanking guide hole 610 connecting the reversing outlet 514 and the material trough 60 is formed on the blanking guide 61. The material trough 60 is provided with a pushing sensor 62 corresponding to the blanking guide 61. The end of the feeding end of the material trough 60 forms a pushing opening. The pushing assembly 70 includes a pushing cylinder 71 and a pushing block 72. One end of the pushing block 72 is connected to the pushing cylinder 71, and the other end extends into the material trough 60 from the pushing opening. The pushing cylinder 71 is configured so that the pushing stroke is consistent with the width of the plunger 10, that is, the pushing cylinder 71 pushes the plunger 10 in the material trough to move a plunger 10 width each time.

[0069] The unloading assembly 80 and the feeding pipe 90 are arranged one by one on both sides of the unloading end 602 of the material trough 60. The material trough 60 corresponds to the openings on both sides of the unloading assembly 80. The number of unloading assemblies 80 can be one or more according to actual production needs. In the embodiment of the present application, the number of unloading assemblies 80 is two.

[0070] In this embodiment, the material discharge assembly 80 includes a material discharge cylinder 81 and a material discharge push block 82. One end of the material discharge push block 82 is connected to the material discharge cylinder 81, and the other end extends from the side of the material trough 60, and is used to push the plunger 10 at the corresponding position in the material trough 60 to the feeding pipe 90 on the other side under the drive of the material discharge cylinder 81. The distance D between the material discharge guide hole 610 and the material discharge push block 82 in the second direction is X is an integer multiple of the width dimension k of the plunger 10, that is, D X =nk, A full material sensor 63 is provided at the end of the unloading end of the material trough 60 for sensing whether the material trough is full, thereby facilitating the control of the start and stop of the pushing cylinder 71.

[0071] In the present application, the plunger 10 that has been reversing and adjusted by the blanking assembly 50 does not necessarily all fall in a predetermined posture. In this case, in order to prevent the system from shutting down due to material backflow, the present embodiment also includes a material backflow sensor 64, a material backflow assembly 65 and a material backflow connector 66.

[0072] Among them, the anti-material sensor 64 is arranged between the blanking guide 61 and the blanking component 80, the anti-material component 65 is arranged on the side of the anti-material sensor 64 close to the blanking end 602, and the interval between the anti-material component 65 and the anti-material sensor 64 is a preset integer multiple of the width dimension k of the plunger 10, the anti-material component 65 and the anti-material joint 66 are correspondingly arranged on both sides of the material trough 60, and the material trough 60 has openings on both sides corresponding to the anti-material component 65, the anti-material component 65 includes a anti-material cylinder 651 and a anti-material push block 652, one end of the anti-material push block 652 is connected to the anti-material cylinder 651, and the other end extends from the side of the material trough 60, and the anti-material cylinder 651 is configured so that when the anti-material sensor 64 senses the anti-material and the pushing cylinder 71 pushes a preset integer number of times, the anti-material cylinder 651 drives the anti-material push block 652 to push the plunger 10 at the corresponding position in the material trough to the anti-material joint 66 on the other side.

[0073] For example, in this embodiment, the interval between the reverse material component 65 and the reverse material sensor 64 is 6 times the width dimension k of the plunger 10. When the reverse material sensor 64 senses the reverse material and the pushing cylinder 71 pushes 6 times, the reverse material just reaches the corresponding position of the reverse material component 65. At this time, the reverse material cylinder 651 drives the reverse material pushing block 652 to push the plunger 10 at the corresponding position in the material trough to the reverse material joint 66 on the other side, which can effectively remove the reverse material. In order to fill the gaps left by the reverse material, the next pushing cylinder 71 can be designed to push twice in a row, or the next pushing distance can be twice the width dimension k of the plunger 10.

[0074] In a preferred embodiment of the present application, the feeding pipeline 90 includes a feed connector 91 and a delivery pipe 92 which are connected to each other. A plunger walkway 911 and a plunger port 912 are formed at the upper end of the feed connector 91. The delivery pipe 92 is connected to the lower end of the feed connector 91 and communicates with the plunger port 912. A blowing port communicating with the delivery pipe 92 is formed on the side of the feed connector 91. Preferably, a pipeline feed sensor 921 is provided near the feed connector 91 for sensing the feeding of the delivery pipe 92.

[0075] It is understandable that the above-mentioned automatic feeder as a whole is in the actual production process. Fig.10 As shown, it is relatively fixedly installed on a fixed bracket 100 inside the workshop to ensure the stable operation of the entire machine. The fixed bracket 100 can be hollow or closed with a switchable door panel. The lower end of the fixed bracket is preferably connected with a height-adjustable support foot, and the electric control cabinet 200 is installed on the fixed bracket 100.

[0076] In order to have a more comprehensive understanding of the embodiments of the present application, the fully automatic feeding process of the present embodiment is described in detail below:

[0077] After the device is started, combine Figures 1 to 10As shown, a sufficient amount of plunger 10 raw material is added to the inside of the shell 21 from the feeding port 211 manually or automatically, and the feeding belt 22, driven by the feeding cylinder and the one-way bearing, transports the plunger 10 raw material from the lower end to the higher end. Then, the plunger 10 raw material enters the feed trough 300 of the plunger vibration disk 30 from the feeding outlet pipe 212, and the vibration disk sensor continuously senses the amount of raw material inside the feed trough 300. When the amount is insufficient, the feeding signal is fed back to the electric control cabinet, and the feeding belt 22 starts feeding again.

[0078] The plungers entering the feed trough 300 of the plunger vibration plate 30 are dispersed as the plunger vibration plate 30 vibrates, and enter the conveyor belt 41 in turn in a transverse direction at the discharge port of the plunger vibration plate 30 .

[0079] Under the action of the conveyor belt 41, the plunger 10 located on the conveyor belt 41 reaches the discharge end 402 of the conveyor belt assembly 40, and passes through the blanking reversing of the blanking assembly 50, so that almost all of the plungers 10 fall out from the reversing outlet 514 in a vertical posture with the second end 102 facing downward, that is, fall out in a forward direction, and enter the blanking guide hole 610 of the blanking guide 61.

[0080] When the push sensor 62 senses that there is material, the conveyor belt motor 42 will not start. When there is no material in the push sensor 62, the conveyor belt motor 42 will start, and the conveyor belt 41 will be driven to move through the synchronous belt, thereby transporting the plunger 10 material.

[0081] It can be understood that when the conveyor belt material sensor 46 does not sense the presence of material, the plunger vibration plate 30 will be started to transport the plunger 10 material to the conveyor belt 41. When the push material sensor 62 has no material and the drop material sensor 54 senses the presence of material, the drop material cylinder will be started.

[0082] Preferably, the front stopper unit 48 and the rear stopper unit 49 are controlled by the same solenoid valve. When the cylinder of the front stopper unit 48 moves forward, the cylinder of the rear stopper unit 49 moves backward; when the cylinder of the rear stopper unit 49 moves forward, the cylinder of the front stopper unit 48. When the material sensor 54 senses that there is no plunger 10 material, the cylinder of the front stopper unit 48 will move backward, and the cylinder of the rear stopper unit 49 moves forward, and the plunger 10 material stuck in the cylinder of the front stopper unit 48 is transported forward. When the material sensor senses that there is material, the cylinder of the front stopper unit 48 moves forward, and the cylinder of the rear stopper unit 49 moves backward, the front stopper unit 48 blocks the plunger 10 material sent by the conveyor belt 41, and the rear stopper unit 49 opens and then sends away the plunger 10 material released by the front stopper 48. In this way, only one plunger 10 material is sent to the material dropping position each time, preventing the system from getting stuck.

[0083] After the push sensor 62 senses the presence of material, it determines that the cylinder for feeding the material into the subsequent machine tool processing is at the rear limit, and the push cylinder 71 also needs to be at the rear limit to ensure that no more material is pushed into the material trough 60. In addition, the reverse material cylinder 651 at this time also needs to be at the rear limit to prevent the reverse material cylinder 651 from being pushed out, causing the push cylinder 71 to be unable to push the plunger 10 to move in the material trough 60. At the same time, the induction light of the full material sensor 63 needs to be turned off to ensure that the material trough 60 is not full of material. According to the control of the PLC in the electric control cabinet, after the above conditions are met, the push cylinder 71 will push the plunger 10 of the material trough 60 The width of the material installer moves forward one grid.

[0084] When the material is sent to the reverse material sensor 64, the reverse material sensor 64 will judge whether the plunger material under the reverse material sensor 64 is on the front side or the back side according to the intensity of the light reflected back by the front and back materials. In the PLC, if the plunger 10 material sensed by the reverse material sensor 64 is reverse material, the reverse material signal will be assigned to the storage unit inside the PLC, and after 6 times of pushing the material, the reverse material just reaches the pushing position of the reverse material cylinder 651. At this time, the PLC sends the reverse material pushing signal to the reverse material cylinder 651, driving the reverse material pushing block 652 to push the plunger 10 at the corresponding position in the material trough to the reverse material joint 66 on the other side.

[0085] After the plunger 10 has gone through the previous steps, it will continue to push forward. As the falling materials are pushed into the material trough 60 one by one, the material in the material trough 60 will be filled. The full material sensor 63 senses it and proves that the material trough 60 is full of material. At this time, the two push cylinders 71 are also at the rear limit, the blowing of the feed joint 91 is not turned on, and the processing machine tool gives the signal of loading enable and starting feeding, then the two push cylinders 71 start to push the plunger 10 material into the corresponding feeding pipe 90. After the pipeline feeding sensor senses the plunger 10 pushed down in the feeding pipe 90, it immediately starts blowing, and blows the plunger 10 material in the feeding pipe 90 to the machine tool for processing. The sensor on the machine tool in the subsequent process senses the arrival of the plunger and stops blowing. The delivery of the plunger 10 material is completed at this point.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
