Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an automatic feeding system. Background Technology

[0002] Powdered additives are used in rubber production. These additives are weighed and produced according to the process formula by an automatic powder batching system, then packaged into powder packages and placed into loading containers. After production, the system automatically records the process data into reports. Then, a manual worker removes the powder packages from the loading containers at the material handling station and places them onto a transfer cart. The cart is then manually transported to the rubber weighing station of the internal mixing system in the rubber production equipment. The type and weight of the material in the transfer cart are verified manually. Once the weight is verified, the powder is fed into the internal mixer of the rubber production equipment according to the production process requirements. Because the material handling, transfer, and verification processes are generally performed manually, and large-scale rubber production processes require tens or even hundreds of kilograms of powder, this not only results in high labor intensity and low transfer efficiency, but also increases the risk of package breakage during powder transfer and errors such as misuse, similar weights, and / or expired powder during verification. Therefore, an automatic feeding device is urgently needed to automate material handling, transfer, and verification. Utility Model Content

[0020] The present invention achieves the following technical advantages over the prior art:

The electronic tag records information such as material type, weight, and validity. The identification mechanism of the verification device can identify and verify the information on the electronic tag, verifying whether the material in the loading container meets the process requirements. If it meets the requirements, the weight of the material is verified by the weighing mechanism of the verification device. If the verification is successful, the material is transported to the feeding device through the output device and fed into the production equipment. If the verification fails, the material is discharged through the error-detection device. The entire process is automated without human intervention, which can not only effectively improve efficiency, but also avoid damage during transportation and errors caused by manual verification, as the material is located inside the loading container.

However, in the automatic feeding system of this utility model, the electronic tag also contains material production process data. The identification mechanism of the verification device can transmit the material production process data to the production settings, which is conducive to tracing the production status of materials and other information. When applied to rubber production, it can solve the above problems. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] This embodiment provides an automatic feeding system, such as Figures 1 to 19As shown, the system includes a loading container 1, an input device 2, a verification device 3, an error-correcting device 4, an output device 5, and a feeding device 6. The loading container 1 is used to load materials and attach electronic tags. The electronic tags include at least material type information, material weight information, and material expiration date. The input device 2 receives and conveys the loading container 1 containing materials along the process flow. The verification device 3 includes a bidirectional conveying mechanism, an identification mechanism, and a weighing mechanism. The bidirectional conveying mechanism conveys the loading container 1 bidirectionally between the input device 2 and the weighing mechanism. The identification mechanism identifies the information in the electronic tags and verifies the material type and expiration date. The identification mechanism is located on the conveying path of the bidirectional conveying mechanism. The weighing mechanism weighs the material and compares the weight with the material weight information in the electronic tag to verify the material weight information. The error-correcting device 4 receives loading containers 1 that fail verification from the input device 2 and discharges them. The output device 5 receives loading containers 1 that pass verification from the input device 2 and continues to convey them along the process flow. The feeding device 6 is used to receive the loading container 1 conveyed by the output device 5 and to feed the material in the loading container 1 into the production equipment 7.

[0054] Working principle:

[0055] After the loading container 1 containing materials is sent to the input device 2, the input device 2 will transport the loading container 1 to the verification device 3. The bidirectional conveying mechanism of the verification device 3 will receive the loading container 1 and transport it to the weighing mechanism. During the transport process, the identification mechanism will identify the electronic tag on the loading container 1 to obtain the material type information, material expiration date information, and material weight information. If the material type information and material expiration date information are verified to be correct, the bidirectional conveying mechanism will continue to transport the material, and the weighing mechanism will weigh the loading container 1. If the verification is not qualified, the material will be transported back to the input device 2. The weighing mechanism will obtain the material weight information (automatically excluding the weight of the loading container 1 itself) and compare it with the identified material weight information to determine whether it is qualified. Then, the bidirectional conveying mechanism will transport the loading container 1 back to the input device 2. Qualified loading containers 1 will be transported to the output device 5, and from the output device 5, they will be transported to the feeding device 6. Then, the feeding device 6 will feed the material in the loading container 1 into the production equipment 7 for production. Qualified loading containers 1 will be transported to the error removal device 4 for discharge. After discharge, they can be manually processed.

[0056] In one implementation, such as Figures 1 to 19 As shown, production equipment 7 is rubber production equipment, and the material is powdered additives.

[0057] In one implementation, such as Figures 1 to 19As shown, the electronic tag also includes material production process data, and the identification mechanism can transmit the material production process data information to the production equipment 7. Specifically, the identification mechanism and the production equipment 7 can be connected via Ethernet, and data interaction can be performed using a database intermediate table to obtain production process data, facilitating subsequent data traceability.

[0058] In one implementation, such as Figures 1 to 19 As shown, it also includes a control device, which coordinates the control of the loading container 1, input device 2, verification device 3, error correction device 4, output device 5, and feeding device 6. The control device includes a PLC controller or a microcontroller.

[0059] In one implementation, such as Figures 1 to 19 As shown, the material is a bag containing powder. Of course, the material can also be a bag containing lumpy material, or even just lumpy material; it is not limited to powder. This powder can be an additive used in the rubber production process, and the corresponding production equipment 7 is rubber production equipment. Alternatively, it can be other materials, in which case the corresponding production equipment 7 can be used.

[0060] In one implementation, such as Figures 1 to 19 As shown, the loading container 1 includes a barrel body 11, with a discharge port at the bottom of the barrel body 11, and a sealing bottom plate 12 hinged to the discharge port. The barrel body 11 is used for loading materials and attaching electronic tags. During transportation, the sealing bottom plate 12 closes to seal the discharge port, preventing the material inside the barrel body 11 from being exposed. When feeding is required, the sealing bottom plate 12 is flipped down to expose the discharge port, allowing the material to fall out naturally. Specifically, the sealing bottom plate 12 can be hinged to the barrel body 11 via a hinge 13 or a similar hinge mechanism.

[0061] In one implementation, such as Figures 1 to 19As shown, the input device 2 includes a lifting track 21, on which a lifting platform 22 is mounted. The lifting platform 22 is equipped with a first roller conveyor line 23 and a first double-speed chain track 24. The first roller conveyor line 23 conveys horizontally, and its conveying direction is parallel to the plane of the lifting track 21. The first double-speed chain track 24 conveys horizontally, and its conveying direction is perpendicular to the plane of the lifting track 21. The first double-speed chain track 24 is positioned within the roller gap of the first roller conveyor line 23. The verification device 3, the error correction device 4, and the output device 5 are all located beside the lifting path of the lifting platform 22. The verification device 3 is located in the conveying direction of the first double-speed chain track 24, and the output device 5 and the error correction device 4 are both located in the conveying direction of the first roller conveyor line 23. The verification device 3, the output device 5, and the error correction device 4 can be at the same height or at different heights, depending on actual needs and space requirements. Preferably, the output device 5 and the error correction device 4 are located in opposite conveying directions of the first roller conveyor line 23.

[0062] Working principle: Initially, the lifting platform 22 is located at the bottom of the lifting track 21. Other conveying equipment (not shown) sends the loading container 1 containing materials to the first double-speed chain track 24 of the lifting platform 22. The first double-speed chain track 24 conveys in the forward direction, transporting the loading container 1 to the first roller conveyor line 23. Then, the lifting platform 22 rises to the calibration device 3, and the first double-speed chain track 24 conveys in the reverse direction, sending the loading container 1 to the calibration device 3 for calibration. After calibration, the loading container 1 is sent back to the first double-speed chain track 24, which then conveys in the forward direction, transporting the loading container... 1. If the loading container 1 passes the inspection, the lifting platform 22 moves to the output device 5 (including rising, falling, or remaining stationary, depending on the height relationship between the output device 5 and the inspection device 3), and the loading container 1 is transported to the output device 5 by the first roller conveyor 23. If the loading container 1 fails the inspection, the lifting platform 22 moves to the error removal device 4 (including rising, falling, or remaining stationary, depending on the height relationship between the output device 5 and the inspection device 3), and the loading container 1 is transported to the error removal device 4 by the first roller conveyor 23, and discharged by the error removal device 4.

[0063] In one implementation, such as Figures 1 to 19 As shown, the lifting platform 22 is also equipped with guide rollers 25. The guide rollers 25 are arranged along the conveying direction of the first roller conveyor line 23, the axis of the guide rollers 25 is set vertically, and the guide rollers 25 are located between the first double-speed chain track 24 and the lifting track 21.

[0064] In one implementation, such as Figures 1 to 19As shown, the lifting platform 22 can be raised and lowered by a drive chain. Specifically, a drive chain and a drive sprocket are installed inside the lifting rail 21. The lifting platform 22 is slidably connected to the lifting rail 21, and the lifting platform 22 and the drive chain are fixedly connected. A drive motor is installed outside the lifting rail 21. The drive motor drives the drive sprocket to rotate, which in turn drives the drive chain to rotate, thus raising and lowering the lifting platform 22. Alternatively, the lifting platform 22 can be driven by a screw and nut. The screw is installed inside the lifting rail 21, and the nut is rotatably connected to the lifting platform 22. The screw and nut are threaded together, and the screw is driven by a drive motor. The lifting platform 22 is slidably connected to the lifting rail 21, and the rotation of the screw drives the nut to rise and fall, thus raising and lowering the lifting platform 22. The lifting platform 22 can also be raised and lowered by a rack and pinion mechanism. The rack is fixed to the lifting rail 21, and the gear is rotatably connected to the lifting platform 22. The gear and rack mesh, and a drive motor is installed on the lifting platform 22 to drive the gear to rotate. The lifting platform 22 is slidably connected to the lifting rail 21, and the rotation of the gear drives the lifting platform 22 to rise and fall. Of course, the above are just a few simple examples. Any method that can achieve the lifting of the lifting platform 22 can be adopted according to actual needs.

[0065] In one implementation, such as Figures 1 to 19As shown, the bidirectional conveying mechanism includes a suspended second-speed chain track 31. The suspension method can be varied, such as installing a support frame 8 on the ground and mounting the second-speed chain track 31 on the support frame 8, or hanging it from the factory ceiling and fixing the second-speed chain track 31 to the hanger. The specific method used depends on actual needs and factory space requirements. The second-speed chain track 31 can overlap with the conveying direction of the first-speed chain track 24 on the lifting path of the lifting platform 22. That is, when the lifting platform 22 rises and falls, the second-speed chain track 31 and the first-speed chain track 24 can connect, allowing the second-speed chain track 31 to receive the loading container 1 from the first-speed chain track 24, or to send the loading container 1 back to the first-speed chain track 24. The identification mechanism includes a radio frequency identification (RFID) device 32, which is located beside the second double-speed chain track 31. The radio frequency direction of the RFID device 32 is perpendicular to the conveying direction of the second double-speed chain track 31, enabling the RFID device 32 to identify the electronic tag during the conveying of the loading container 1 to the weighing mechanism. The weighing mechanism includes an electronic scale 33 and a lifting device 34. The electronic scale 33 is located between the two tracks of the second double-speed chain track 31. The lifting device 34 can drive the electronic scale 33 to rise and fall. When the second double-speed chain track 31 delivers the loading container 1 above the electronic scale 33, the lifting device 34 drives the electronic scale 33 to rise, lifting the loading container 1 away from the second double-speed chain track 31 for weighing. After weighing, the lifting device 34 drives the electronic scale 33 to fall, placing the loading container 1 back on the second double-speed chain track 31, which then sends the loading container 1 back to the first double-speed chain track 24.

[0066] In one implementation, such as Figures 1 to 19 As shown, the error correction device 4 includes a second roller conveyor line 41. The second roller conveyor line 41 can overlap with the conveying direction of the first roller conveyor line 23 on the lifting path of the lifting platform 22. That is, when the lifting platform 22 is raised to a certain position, the second roller conveyor line 41 and the first roller conveyor line 23 can connect, and the second roller conveyor line 41 can receive the unqualified loading container 1 conveyed by the first roller conveyor line 23. Preferably, the error correction device 4 is located below the verification device 3 and can be set on the ground. At the same time, the error correction device 4 and the output device 5 are respectively set in two conveying directions of the first roller conveyor line 23. That is, the first roller conveyor line 23 can send the loading container 1 to the output device 5 in the forward direction, and the first roller conveyor line 23 can send the loading container 1 to the error correction device 4 in the reverse direction. Of course, this is only a preferred method and can be adjusted according to specific needs.

[0067] In one implementation, such as Figures 1 to 19As shown, the output device 5 includes a suspended third roller conveyor 51. The suspension can be achieved by installing a support frame 8 on the ground, with the third roller conveyor 51 mounted on the support frame 8, or by installing a hanger on the factory ceiling, with the second double-speed chain track 31 fixed to the hanger. The specific method used depends on actual needs and factory space requirements. The third roller conveyor 51 and the second double-speed chain track 31 can share a single support frame 8 or hanger. The third roller conveyor 51 can overlap with the conveying direction of the first roller conveyor 23 on the lifting path of the lifting platform 22. That is, when the lifting platform 22 is raised to a certain point, the first roller conveyor 23 and the third roller conveyor 51 can connect, with the third roller conveyor 51 receiving the qualified material loading container 1 conveyed by the first roller conveyor 23. Preferably, the third roller conveyor 51 and the second double-speed chain track 31 can be at the same height, but they can also be at different heights, depending on actual needs and factory space requirements.

[0068] In one implementation, such as Figures 1 to 19 As shown, the feeding device 6 includes a gripper mechanism located behind the end of the third roller conveyor line 51, with the gripper jaws facing the third roller conveyor line 51. After the loading container 1 is conveyed to the end by the third roller conveyor line 51, the barrel 11 that continues to transport the loading container 1 will be gripped by the gripper mechanism, while the bottom cover plate 12 will be suspended without support. Subsequently, the bottom cover plate 12 will flip down, exposing the discharge port, and the material will be naturally discharged from the discharge port under the action of gravity, falling into the feed port of the production equipment 7.

[0069] In one implementation, such as Figures 1 to 19 As shown, the gripper mechanism includes a U-shaped frame 61, grippers 62, and a telescopic cylinder 63. The U-shaped frame 61 is fixedly installed at the end of the third roller conveyor line 51. The opening of the U-shaped frame 61 faces the third roller conveyor line 51, and the opening of the U-shaped frame 61 forms a suspended area. There are two grippers 62, which are horizontally rotatably connected to the two arms of the U-shaped frame 61. Each set of grippers 62 is driven to rotate by the telescopic cylinder 63, so as to open and close the grippers 62 and clamp the barrel 11.

[0070] In one implementation, such as Figures 1 to 19 As shown, each gripper 62 also has an insertion slot, and the barrel extension of the barrel body 11 is provided with a plug-in block 14. The height of the plug-in block 14 corresponds to the height of the insertion slot. When the gripper 62 is closed, the plug-in block 14 will be inserted into the insertion slot. This can limit the barrel body 11 in the height direction and avoid the problem that the barrel body 11 will fall because the barrel body 11 is too smooth or the total weight of the barrel body 11 and the material is too large, and the gripper 62 alone cannot clamp the barrel body 11.

[0071] In one implementation, such as Figures 1 to 19As shown, the surface of the barrel 11 can be treated with anti-slip material to improve the clamping force of the gripper 62. Anti-slip treatments include roughening the surface of the barrel 11 or applying anti-slip rubber or anti-slip coating, etc.

[0072] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
