Description

Technical Field

[0001] This utility model relates to the technical field of proportioning equipment, and in particular to an automatic batching mechanism. Background Technology

[0002] Existing daily chemical fragrances, food flavorings, tobacco flavorings, and essential oils typically require a dozen or even dozens of raw materials blended in specific proportions. These raw materials include fine chemical raw materials and liquid raw materials purified from natural plants. They can be categorized as: alcohols, lipids, ethers, ketones, and aldehydes. Alcohols include ethanol, linalool, and leucopicrin; lipids include ethyl acetate, terpineol acetate, and cyclopentadecanol; ethers include p-cresol methyl ether, rose ether, and diphenyl ether; ketones include vanillin, ethionone, and ambroxol; aldehydes include coconut aldehyde, peach aldehyde, and blue aldehyde; and oils include sweet orange oil, Argentine lemon oil, and lavender oil.

[0003] Traditional manual mixing methods require operators to manually inject and mix a dozen or even dozens of raw materials into a mixing container to prepare the required reagent.

[0004] The existing manual ingredient preparation method has the following problems: it requires manually finding the corresponding raw materials and adding them to the ingredient container. Adding each raw material manually is time-consuming, especially when there are many types of raw materials, the whole process becomes extremely lengthy and the ingredient preparation efficiency is low.

[0005] Therefore, there is an urgent need for a batching mechanism that can replace manual labor to achieve automatic feeding. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide an automatic dispensing mechanism.

[0007] This utility model is achieved through the following technical solution: an automatic dispensing mechanism, including a frame and a rotary push-pull device, a guide block assembly is provided on the frame, the guide block array is composed of a number of sliders arranged in a circular array, each slider is slidably connected to a guide rail, the guide rail is arranged along the radial direction of the guide block assembly, and a liquid injection component is provided at one end of the guide rail.

[0008] The rotary push-pull device includes a rotary drive component and a rotary frame. The rotary drive component is connected to the rotary frame, which is located inside the slider assembly. A linear module is installed on the rotary frame, and a push-pull arm is installed on the linear module. The injection component is provided with a push-pull groove. When the push-pull arm rotates, the push-pull groove on the injection component forms an annular channel. The linear module drives the push-pull arm to move radially along the guide block assembly to move one of the injection components.

[0009] Preferably, the injection component is provided with an outlet nozzle.

[0010] Preferably, the push-pull arm is equipped with rollers; the rollers move in the annular channel.

[0011] Preferably, the frame is provided with a magnet support corresponding to the liquid injection component, the magnet support is provided with a magnet, and one end of the liquid injection component is provided with an armature; when the liquid injection component is in the initial position, the magnet attracts the armature on the liquid injection component.

[0012] Preferably, the system also includes a feed pipe and a raw material tank, with the liquid outlet connected to one end of the feed pipe and the other end of the feed pipe connected to the raw material tank. A control valve is installed on the feed pipe.

[0013] Preferably, the rotary drive component is a geared motor.

[0014] Preferably, the injection point is located at the center of the guide block assembly.

[0015] Preferably, the rotating frame is disc-shaped and has clearance grooves.

[0016] Preferably, the number of the injection components is 80-100.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model can replace manual labor to realize automatic feeding operation. The whole process does not require manual intervention, saving time and effort and greatly improving the feeding efficiency.

[0019] 2. In this invention, the injection components are arranged in a circular array, which can accommodate a large number of injection components at the same time, and the overall structure is relatively compact. When the injection component is in the initial position, the armature at one end of the injection component is attracted by a magnet. The attraction of the magnet can accurately position the injection component in the initial position. Without the attraction of the magnet, during the use of the equipment, one or more injection components may move under the action of external force, causing some injection components to be misaligned. The misalignment of the injection components will prevent the push-pull grooves on the injection components from forming a continuous annular channel, which will hinder the movement of the roller in the annular channel. However, this invention effectively solves the above problems by setting a magnet.

[0020] 5. In this utility model, a rotary push-pull device is used to radially push and pull the injection component, allowing it to reach above the mixing container for injection. This method eliminates the need for the mixing container to move during the mixing process; injection is achieved by fixing the mixing container and moving the injection component. This reduces positioning errors that may be caused by moving the mixing container, thus improving the accuracy of the injection position. Furthermore, this method avoids liquid splashing or instability that may result from moving the mixing container, which is especially important when handling high-precision, easily splashed, or materials with high stability requirements. This method eliminates the need for a complex conveying system to precisely control the position of the mixing container, reducing equipment complexity and maintenance costs, while also lowering the failure rate.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] like Figures 1 to 8As shown, an automatic batching device includes a control system, a feeding conveyor line 1, a discharging conveyor line 2, an inlet side rail 3, an outlet side rail 4, and a transition conveyor line 7. Several automatic batching mechanisms 9 and batching conveyor lines are arranged between the inlet side rail 3 and the outlet side rail 4, and the batching conveyor lines correspond one-to-one with the automatic batching mechanisms 9.

[0034] A first trolley 5 is installed on the inlet side rail 3, and a second trolley 6 is installed on the outlet side rail 4. One end of the inlet side rail is the receiving end, and the other end of the outlet side rail 4 is the turning end. One end of the feeding conveyor line 1 and one end of the transition conveyor line 7 are corresponding to the receiving end of the inlet side rail 3, and one end of the unloading conveyor line 2 and the other end of the transition conveyor line 7 are corresponding to the turning end of the outlet side rail 4.

[0035] The first trolley 5 is used to receive the batching container 11 transferred from the feeding conveyor line 1 or the transition conveyor line 7 and transfer the batching container 11 to the batching conveyor line; the second trolley 6 is used to receive the batching container 11 transferred from the batching conveyor line and transfer the batching container 11 to the unloading conveyor line 2 or the transition conveyor line 7; the automatic batching mechanism 9 is used to inject raw materials into the batching container 11 on the batching conveyor line.

[0036] In this utility model, the feeding conveyor line 1, the unloading conveyor line 2, the batching conveyor line and the transition conveyor line 7 all adopt roller conveyor lines.

[0037] The outer side of the ingredient container 11 is provided with an identification code for storing ingredient information, and a barcode scanning device is provided on one side of the receiving end of the inlet track 3. The ingredient information includes the types of all raw materials to be injected into the ingredient container 11. In addition, the ingredient information also includes the required weight of each raw material. The identification code used in this utility model is a QR code or a barcode.

[0038] A batching station is provided on the batching conveyor line; when the automatic batching mechanism 9 injects raw materials into the batching container 11 on the batching conveyor line, the batching container 11 stays at the batching station; a weighing device 10 for weighing the batching container 11 is provided below the batching station. Specifically, the weighing device 10 includes a fixed frame 8-1, a lifting device 8-2 is provided on the fixed frame 8-1, a weighing sensor 8-3 is provided at the upper end of the lifting device 8-2, and a contact part 8-4 for contacting the bottom of the batching container 11 is provided on the weighing sensor 8-3.

[0039] The lifting device 8-2 can be powered by a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The lifting drive device 14-1 is used to drive the weighing sensor 8-3 and the contact component 8-4 to move up and down. The weighing sensor 8-3 is electrically connected to the control system. When the weighing device 10 is not in operation, the upper end of the contact component 8-4 is lower than the upper surface of the batching conveyor line. At this time, when the batching container 11 is located at the batching position and is about to be batched, the lifting device 8-2 drives the contact component 8-4 to move upward, thereby pressing against the bottom of the batching container 11 and lifting the batching container 11 upward a certain distance, so that the bottom of the batching container 11 is removed from the batching conveyor line. The weighing sensor 8-3 weighs the batching container 11; by detecting the weight difference of the batching container 11 before and after each injection, the current injection weight of the raw material can be known.

[0040] In this utility model, the batching conveyor line adopts a roller conveyor line. The contact component 8-4 includes a base plate 8-4a and a top plate 8-4b arranged on both sides above the base plate 8-4a. There is a certain gap between adjacent rollers on the roller conveyor line, and the top plate 8-4b on the contact component 8-4 can pass through the gap.

[0041] Specifically, the automatic batching mechanism 9 includes a frame 9-1, a rotary push-pull device, and a conveying pipe. A guide block assembly is mounted on the frame 9-1. The guide block array 9-12 consists of several sliders arranged in a circular array. Each slider is slidably connected to a guide rail 9-6, which is arranged radially along the guide block assembly. One end of the guide rail 9-6 is equipped with a liquid injection component 9-7, which has a liquid outlet. The liquid outlet is connected to one end of the conveying pipe, and the other end of the conveying pipe is connected to the raw material tank 12. A control valve is mounted on the conveying pipe. The rotary push-pull device includes a rotary drive component 9-2 and a rotary frame 9-3. The rotary drive component 9-2 is connected to the rotary frame 9-3, which is located on the slide... Inside the block assembly, a linear module 9-4 is mounted on the rotating frame 9-3, a push-pull arm 9-5 is mounted on the linear module 9-4, and a roller 9-8 is mounted on the push-pull arm 9-5; the injection component 9-7 is provided with a push-pull groove 9-7a; the push-pull arm 9-5 is driven to rotate by the rotation drive component 9-2; when the push-pull arm 9-5 rotates, the push-pull groove 9-7a on the injection component 9-7 together form an annular channel, and the roller 9-8 moves in the annular channel; the push-pull arm 9-5 is driven to move radially along the guide block assembly by the linear module 9-4; when the push-pull arm 9-5 moves, it drives one of the injection components 9-7 to move between the injection position and the initial position, with the injection position located at the center of the guide block assembly.

[0042] In this embodiment, the rotary drive component 9-2 is a geared motor. The guide blocks 9-12 are arranged in a circular array, so that the guide block assembly as a whole has a circular structure.

[0043] When injecting liquid into the mixing container 11, the mixing container 11 moves to the mixing position on the mixing conveyor line, at which point the mixing container 11 is just below the liquid injection position. The push-pull arm 9-5 first rotates to the liquid injection component 9-7 of the raw material to be added, and then pulls the liquid injection component 9-7 to the liquid injection position by the radial movement of the push-pull arm 9-5. Then, the control valve on the conveying pipe connected to the liquid injection component 9-7 is opened, and the raw material in the raw material tank 12 is injected into the mixing container 11 through the conveying pipe and the liquid outlet. After the raw material injection is completed, the control valve is closed, and the push-pull arm 9-5 pushes the liquid injection component 9-7 to the initial position. Then, the push-pull arm 9-5 rotates to the liquid injection component 9-7 corresponding to the next raw material, and the next raw material is injected in the same way.

[0044] For example, when an automatic dispensing mechanism 9 needs to inject three kinds of raw materials into the dispensing container 11, the roller 9-8 on the push-pull arm 9-5 first rotates into the push-pull groove 9-7a on the injection component 9-7 corresponding to the first raw material. Then, the linear module 9-4 drives the push-pull arm 9-5 to move radially, pulling the injection component 9-7 to the injection position. Then, the control valve on the conveying pipe connected to the injection component 9-7 opens, and the raw material in the raw material tank 12 is injected into the dispensing container 11 through the conveying pipe and the liquid outlet. After the first raw material is injected, the control valve closes, and the push-pull arm 9-5 pushes the injection component 9-7 to move to the initial position. Then, the second and third raw materials are injected in the same way.

[0045] In this embodiment, an automatic dispensing mechanism 9 is equipped with 80-100 liquid dispensing devices, meaning that an automatic dispensing mechanism 9 can dispense 80-100 kinds of raw materials. The entire set of equipment contains a total of four automatic dispensing mechanisms 9, and the entire set of equipment can dispense up to 320-400 kinds of raw materials, thereby effectively meeting the dispensing needs of some complex reagents.

[0046] This utility model also includes a raw material tank storage rack 13, on which all raw material tanks 12 are stored uniformly.

[0047] The rotating frame is disc-shaped and equipped with clearance grooves 9-13. The clearance grooves 9-13 are straight grooves arranged radially along the rotating frame. When the push-pull arm 9-5 pulls a certain injection component 9-7 to the injection position, the clearance groove rotates to the position corresponding to that injection component 9-7, and the injection component 9-7 moves within the clearance groove.

[0048] Furthermore, a magnet bracket 9-9 corresponding to the liquid injection component 9-7 is provided on the frame 9-1, and a magnet 9-10 is provided on the magnet bracket 9-9. An armature 9-11 is provided at one end of the liquid injection component 9-7. When the liquid injection component 9-7 is in the initial position, the magnet 9-10 is attracted to the armature 9-11 on the liquid injection component 9-7. When the injection component 9-7 is in the initial position, the armature 9-11 at one end of the injection component 9-7 is attracted by the magnet 9-10. The attraction of the magnet 9-10 allows the injection component 9-7 to be precisely positioned in the initial position. Without the attraction of the magnet 9-10, during use, one or more injection components 9-7 may move under the action of external force, causing misalignment. This misalignment will prevent the push-pull groove 9-7a on the injection component 9-7 from forming a continuous annular channel, which will hinder the movement of the roller 9-8 in the annular channel. The present invention effectively solves the above problem by setting the magnet 9-10.

[0049] The first trolley 5 includes a first movable chassis 5-1 that can move along the entry side track 3. A first rotating device 5-2 is mounted on the first movable chassis 5-1. A first support frame 5-3 is mounted on the first rotating device 5-2. A first roller conveyor mechanism 5-4 is mounted on the first support frame 5-3. The second trolley 6 includes a second movable chassis that can move along the entry side track 3. A second rotating device is mounted on the second movable chassis. A second support frame is mounted on the second rotating device. A second roller conveyor mechanism is mounted on the second support frame.

[0050] The first rotating device 5-2 drives the first support frame 5-3 to rotate, thereby adjusting the orientation of the first support frame 5-3. The first roller conveying mechanism 5-4, mounted on the first support frame 5-3, is driven by a motor to rotate the rollers, which is used to move the dispensing container 11 on and off the first support frame 5-3. For example, when the dispensing container 11 on the feeding conveyor line 1 needs to be moved to the first support frame 5-3, the first rotating device 5-2 first drives the first support frame 5-3 to rotate, making it face and align with the feeding conveyor line 1. The dispensing container 11 is then transferred to the first support frame 5-3 via the feeding conveyor line 1 and the first roller conveying mechanism 5-4 on the first support frame 5-3.

[0051] Similarly, the second rotating device drives the second support frame to rotate, thereby adjusting the orientation of the second support frame. The second roller conveyor mechanism, mounted on the second support frame, is driven by a motor to rotate the rollers, used to move the dispensing container 11 in and out of the second support frame. For example, when the dispensing container 11 on the second support frame needs to be moved to the unloading conveyor line 2, the second rotating device first drives the second support frame to rotate, making it face and align with the unloading conveyor line 2. The dispensing conveyor line 2 and the second roller conveyor mechanism on the second support frame then transfer the dispensing container 11 onto the unloading conveyor line 2.

[0052] Among them, a blocking and releasing device 14 is installed at one end of the batching conveyor line near the output side track 4, one end of the transition conveyor line 7 near the receiving end, and the batching position of the batching conveyor line. The blocking and releasing device 14 includes a driving device 14-1 and a blocking bar 14-2 connected to the driving device 14-1. The driving device 14-1 drives the blocking bar 14-2 to rotate.

[0053] The drive device 14-1 drives the barrier bar 14-2 to rotate, and the rotation of the barrier bar 14-2 switches between the blocking state and the release state. For example, when the batching container 11 is located at the batching position and is about to be batched, the barrier release device 14 located at the batching position is in the blocking state, and the barrier bar 14-2 is positioned horizontally in front of the batching container 11, so that the batching container 11 is accurately located at the batching position; after the batching is completed, the barrier bar 14-2 rotates upward and the barrier release device 14 is in the release state, so that the batching container 11 can pass.

[0054] An automated ingredient dispensing method includes the following specific steps:

[0055] Step 1: The feeding container 11 on the feeding conveyor line 1 is transferred to the first trolley 5 at the receiving end. The scanning device scans the identification code on the feeding container 11. The control system reads the feeding information, determines the total number of feedings and the automatic feeding mechanism 9 that the feeding container 11 needs to pass through in each feeding. This automatic feeding mechanism 9 is the target automatic feeding mechanism 9.

[0056] Step 2: Determine the number of times the current ingredient is dispensed and determine if this is the last batch of ingredients. The number of times the current ingredient is dispensed is determined by the number of scans. For example, if the identification code is scanned for the second time during a batch, the number of times the current ingredient is dispensed is 2. If the identification code is scanned for the first time during a batch, the number of times the current ingredient is dispensed is 1.

[0057] The method for determining whether the current ingredient is the last ingredient is as follows: if the number of times the current ingredient is added is less than the total number of times the ingredients are added, then the current ingredient is not the last ingredient; if the number of times the current ingredient is added is equal to the total number of times the ingredients are added, then the current ingredient is the last ingredient.

[0058] Step 3: The first trolley 5 transports the batching container 11 to the target automatic batching mechanism 9 corresponding to the current batching. The batching container 11 is transferred from the first trolley 5 to the batching conveyor line corresponding to the target automatic batching mechanism 9. After the batching container 11 moves to the batching position on the batching conveyor line, it stops. At this time, the contact part 8-4 on the weighing device 10 moves upward to press against the bottom of the batching container 11 and lift the batching container 11 upward. The target automatic batching mechanism 9 injects the required types of raw materials into the batching container 11 in sequence. The weight of the raw materials injected each time is detected by the weighing sensor 8-3. After the raw materials are injected, the batching container 11 continues to move forward. The second trolley 6 moves to the position corresponding to the batching container 11, and the batching container 11 is transferred to the second trolley 6. The second trolley 6 moves to the turn-out end on the output side track 4.

[0059] Step 4: If the current batching is the last batching, the second trolley 6 transfers the batching container 11 to the unloading conveyor line 2; if the current batching is not the last batching, the second trolley 6 transfers the batching container 11 to the transition conveyor line 7, and then the transition conveyor line 7 transfers the batching container 11 to the first trolley 5 in the receiving position. The scanning device scans the barcode on the batching container 11, and steps 2 to 4 are repeated.

[0060] The following is a specific example of an automated ingredient dispensing method:

[0061] The automatic batching equipment has a total of four automatic batching mechanisms 9, designated as Automatic Batching Mechanism 1, Automatic Batching Mechanism 2, Automatic Batching Mechanism 3, and Automatic Batching Mechanism 4, arranged sequentially. Automatic Batching Mechanism 1 is closest to the feeding conveyor line 1, while Automatic Batching Mechanism 4 is furthest from it. The types of raw materials that each automatic batching mechanism 9 can handle are known and pre-stored in the control system.

[0062] Reagent A needs to be prepared. Reagent A is prepared from eight raw materials: raw material A, raw material B, raw material C, raw material D, raw material E, raw material F, raw material G, and raw material H. At this time, the ingredient information stored in the identification code on the ingredient container 11 includes the name of each raw material used to prepare reagent A and the weight of each raw material.

[0063] Among them, the No. 1 automatic dispensing mechanism has a liquid injection component 9-7 capable of injecting raw materials A, B, and C; the No. 2 automatic dispensing mechanism has a liquid injection component 9-7 capable of injecting raw materials E and F; and the No. 3 automatic dispensing mechanism has a liquid injection component 9-7 capable of injecting raw materials G and H. When the dispensing container 11 used to prepare reagent A moves to the first trolley 5 at the receiving end, the barcode scanning device scans the identification code on the dispensing container 11 to read the dispensing information. After obtaining the dispensing information, the control system determines the total number of dispensing operations and the number of automatic dispensing mechanisms 9 that the dispensing container 11 needs to pass through in each dispensing operation. In this example, a total of 3 dispensing operations are required, so the total number of dispensing operations is 3. The first batching process requires passing through automatic batching mechanism 1, so automatic batching mechanism 1 is the target automatic batching mechanism 9 for the first batching process; similarly, the second batching process requires passing through automatic batching mechanism 2, so automatic batching mechanism 2 is the target automatic batching mechanism 9 for the second batching process; the third batching process requires passing through automatic batching mechanism 3, so automatic batching mechanism 3 is the target automatic batching mechanism 9 for the third batching process.

[0064] The control system then determines whether the current batching is the last batching. Since the identification code is being scanned for the first time during the current batching, the count corresponding to the current batching is 1, which is less than the total number of batching counts. Therefore, the current batching is not the last batching.

[0065] Next, the first trolley 5 transports the batching container 11 to the No. 1 automatic batching mechanism. Then, the batching container 11 moves to the batching position on the batching conveyor line corresponding to the No. 1 automatic batching mechanism and stops. The contact part 8-4 on the weighing device 10 lifts the batching container 11 and weighs it. The No. 1 automatic batching mechanism injects raw material A, raw material B, and raw material C into the batching container 11 respectively. After the raw materials are injected, the contact part 8-4 on the weighing device 10 descends, and the batching container 11 moves to the second trolley 6. The second trolley 6 transports the batching container 11 to the turnout end on the output side track 4. Since this batching is not the last batching, the batching container 11 will be transferred to the transition conveyor line 7. The transition conveyor line 7 transfers the batching container 11 to the first trolley 5 at the receiving end.

[0066] Then the scanning device scans the identification code on the ingredient container 11 again, and then the second batching is performed. Raw material E and raw material F are injected into the ingredient container 11 through the No. 2 automatic batching mechanism. After the raw material injection is completed, the ingredient container 11 is moved to the second trolley 6, and the second trolley 6 transports the ingredient container 11 to the turn-out end on the output side track 4. Since this batching is not the last batching, the ingredient container 11 will be transferred to the transition conveyor line 7, and the ingredient container 11 will be transferred to the first trolley 5 at the receiving end through the transition conveyor line 7. Since the second batching is not the last batching, the ingredient container 11 will be transferred to the transition conveyor line 7, and the ingredient container 11 will be transferred to the first trolley 5 at the receiving end through the transition conveyor line 7.

[0067] The scanning device scans the identification code on the dispensing container 11 again, and then performs the third dispensing. Since the number of dispensing cycles corresponds to the total number of dispensing cycles, this dispensing cycle is the last one. During the third dispensing cycle, raw material E and raw material F are injected into the dispensing container 11 by the No. 3 automatic dispensing mechanism. After the raw material injection is completed, the dispensing container 11 moves to the second trolley 6, and the second trolley 6 transports the dispensing container 11 to the transfer end on the output side track 4. Since this dispensing cycle is the last one, the dispensing container 11 will be transferred to the unloading conveyor line 2, thus completing the entire dispensing process.

[0068] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
