DETAILED DESCRIPTION

[0022] The following will be combined Figure 1-3 , a liquid automatic metering and pouring machine for production involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0023] The present invention provides an automatic liquid metering and discharging machine for production, which can not only be used to automatically meter and mix fragrance raw materials of different specifications according to quality requirements, but can also be used to automatically meter and mix other liquid materials.

[0024] In the embodiments of the present application, Figure 1-3 As shown, an automatic liquid metering and discharging machine for production includes: an outbound conveyor belt 2, a first weighing device 3, a return conveyor belt 9, and a manipulator 6. The outbound conveyor belt 2 is used to transfer material barrels; the first weighing device 3 is arranged on the side of the outbound conveyor belt 2 close to the input end; the return conveyor belt 9 is arranged on one side of the outbound conveyor belt 2, for transferring material barrels, and the transfer direction is opposite to the transfer direction of the outbound conveyor belt 2; the manipulator 6 is used to pour the material in the material barrel transferred to the output end of the outbound conveyor belt 2 into the temporary storage container 7; and transfer the material barrel after pouring the material to the input end of the return conveyor belt 9; a second weighing device 11, the second weighing device 11 is arranged on the side of the return conveyor belt 9 close to the input end.

[0025] The uncapped barrel is placed at the input end of the outbound conveyor belt 2 and is then transported to the output end of the outbound conveyor belt 2. The outbound conveyor belt 2 is a roller-type conveyor belt, which is conveniently coupled with a weighing device to transfer the barrel to the first weighing device 3. The first weighing device 3 is embedded in the outbound conveyor belt 2 and is controlled by a bottom telescopic device, such as a cylinder, to move the first weighing device 3 up and down. After the barrel is transferred, the cylinder extends, lifting the first weighing device 3, thereby weighing the barrel.

[0026] After the material barrel is transferred to the first weighing device 3, it is weighed and recorded as W1. Then, when the material barrel is transferred to the output end of the outbound conveyor belt 2, the robot 6 grips and flips it, pouring the material in the barrel into the temporary storage container 7. The clamped and emptied material barrel is then placed on the input end of the return conveyor belt 9. Driven by the return conveyor belt 9, it is transferred to the output end of the return conveyor belt 9. The return conveyor belt 9 adopts a roller conveyor belt, which is convenient for cooperating with the weighing device. The barrel is transferred to the second weighing device 11. The second weighing device 11 is embedded in the return conveyor belt 9 and the bottom telescopic device controls the up and down movement of the second weighing device 11.

[0027] When the material barrel is transferred to the second weighing device 11, the material barrel is weighed and recorded as W2, and then the material barrel is transferred to the output end of the return conveyor belt 9 and is recovered. The weight of the material in the barrel is W2-W1.

[0028] By using the automatic metering and pouring machine provided in this embodiment, spices in different barrels can be automatically mixed according to the required weight, thereby improving the accuracy of the weighing process as much as possible, reducing errors caused by manual operation, and thus improving product quality.

[0029] Of course, in order to further improve the degree of automation, in some embodiments, a decapping machine 1 is further included, which is arranged at the input end of the outbound conveyor belt 2 and is used to decap the barrels. In this way, the action of decapping the barrels after loading can be automated.

[0030] To facilitate loading of the material in the raw material barrel 18, the automatic metering and unloading machine of this embodiment further includes a residual material barrel channel unit 10, a third weighing device 5, and a material suction device 4. The residual material that is sucked onto the outbound conveyor belt 2 during the suction process is called a raw material barrel. After the suction process, it is sent to the return conveyor belt 9 via the transfer conveyor belt and is called a residual material barrel.

[0031] The third weighing device 5 is arranged on the side of the outbound conveyor belt 2 close to the output end; and the third weighing device 5 is controlled to move up and down by the bottom telescopic device, and the residual material barrel channel unit 10 connects the outbound conveyor belt 2 and the return conveyor belt 9, and is used to transport the barrel back and forth between the outbound conveyor belt 2 and the return conveyor belt 9; one end of the residual material barrel channel unit 10 is arranged between the second weighing device 11 and the output end of the return conveyor belt 9, and the other end of the residual material barrel channel unit 10 is arranged between the first weighing device 3 and the third weighing device 5; the suction device 4 is used to suck the material in the barrel on the first weighing device 3 into the barrel on the third weighing device 5.

[0032] The residual material barrel channel unit 10 includes: a transmission conveyor belt 16, a power device 15 and a baffle 17. The two ends of the transmission conveyor belt 16 are respectively connected to the outbound conveyor belt 2 and the return conveyor belt 9; the power device 15 is arranged above the transmission conveyor belt 16, and the baffle 17 is arranged on the power device 15, which is used to drive the barrel to move in the direction of outbound conveyor belt 2-transmission conveyor belt 16-return conveyor belt 9 or return conveyor belt 9-transmission conveyor belt 16-outbound conveyor belt 2.

[0033] After the whole barrel is filled according to the required amount of each raw material, there will inevitably be residual material that needs to be measured. Therefore, this embodiment uses the residual material barrel channel unit 10, the third weighing device 5 and the suction device 4 to measure the residual material before filling.

[0034] After the whole barrel pouring process is completed according to the demand for each raw material, the final tailings demand for a certain raw material may be 1 kg or 1.5 kg. Therefore, the whole barrel pouring process can no longer be used. The raw material barrel can only be used to quantitatively suck the material into the tailings temporary storage barrel through the peristaltic pump and the dosing valve, and then the material can be poured.

[0035] The final tailings intake volume for a particular raw material is determined by the computer system. The required tailings intake volume for that raw material is calculated by subtracting the cumulative volume of the entire barrel from the amount specified in the recipe. The peristaltic pump is controlled by the dosing valve to ultimately achieve tailings intake. Therefore, this embodiment utilizes the residual material barrel channel unit 10, the third weighing device 5, and the suction device 4 to achieve metering of the tailings prior to discharge.

[0036] During the tailings suction process, a tailings temporary storage bucket 12 is first placed on the return conveyor belt 9. When it is transferred to the position opposite to the transmission conveyor belt 16, the return conveyor belt 9 pauses or slows down, and the power device 15 drives the baffle 17 to push the tailings temporary storage bucket 12 onto the transmission conveyor belt 16, and then pushes it to the outbound conveyor belt 2, and then transports it to the third weighing device 5 through the outbound conveyor belt 2.

[0037] At this time, the raw material barrel 18 is placed at the input end of the outbound conveyor belt 2. The stopper provided on the outbound conveyor belt 2 can restrict the temporary storage barrel 12 from continuing to move with the outbound conveyor belt 2. When the raw material barrel 18 moves onto the first weighing device 3, the outbound conveyor belt 2 stops moving, the stopper is retracted, and the suction device 4 is started to suck the material in the raw material barrel 18 into the temporary storage barrel 12. Usually, the temporary storage barrel 12 is empty at the beginning.

[0038] It should be noted that the outbound conveyor belt 2 may also be a segment-controlled roller conveyor belt, so that the transportation of the tail material temporary storage barrel 12 and the raw material barrel 18 can be controlled separately without setting a gear lever.

[0039] The suction device 4 includes a peristaltic pump 13 and a dosing valve 14. The peristaltic pump 13 is used to draw material from the material barrel located on the first weighing device 3 into the material barrel located on the third weighing device 5. The dosing valve 14 is in communication with the third weighing device 5 and controls the suction of the peristaltic pump 13 based on the weight information fed back by the third weighing device 5. The third weighing device 5 below the tailings temporary storage barrel 12 provides the dosing valve 14 with the weight information of the tailings temporary storage barrel 12. The dosing valve 14 controls the suction accuracy based on this feedback. When the suction process is complete, the peristaltic pump 13 is reversed to recover the remaining material in the pipe of the suction device 4.

[0040] The first weighing device 3 can be used to calculate the amount of material lost in each raw material barrel, and the third weighing device 5 can be used to calculate the amount of material gained. The difference between the two needs to be kept within a preset range.

[0041] The extracted raw material barrels 18 are transported through the residual material barrel channel unit 10 to the return conveyor belt 9 for recycling. Similarly, a single residual material storage barrel 12 can be used to hold the contents of four, five, or even more raw material barrels. Once collected, the outbound conveyor belt 2 is activated, transporting the residual material storage barrel 12 to the output end of the outbound conveyor belt 2. The coordinate robot 6 then dumps the contents of the residual material storage barrel 12 into the temporary storage container 7.

[0042] In some embodiments, the first weighing device 3, the second weighing device 11 and the third weighing device 5 are electronic scales. In order to achieve higher precision, the precision of the electronic scales can be high-precision electronic scales.

[0043] In some embodiments, the power device 15 is an electric push rod or a screw assembly driven by a servo motor. Any mechanism capable of driving the baffle 17 to pull or push the barrel can be used. In addition to the two mechanisms described above, linear modules can also be used. These are all relatively mature technologies in the prior art and will not be described in detail here.

[0044] In some embodiments, guide guardrails for guiding and protecting the barrels are provided on the outbound conveyor belt 2 and the return conveyor belt 9. The guide guardrails are used to better transport the barrels and to better turn the barrels when transferring between the return conveyor belt 9 and the outbound conveyor belt 2.

[0045] The beneficial effects of the automatic liquid metering and discharging machine for production provided in this application include but are not limited to:

[0046] 1. The raw materials are automatically measured by the electronic scale on the automatic metering and discharging machine and then automatically poured into the temporary storage container by the robot. The production process is stable and the metering and discharging speed is fast.

[0051] 6. The automatic metering and discharging machine fully automates metering and discharging, reducing the possibility of metering and discharging errors under manual operation, thereby maximizing the quality of the final product.

[0052] 7. When the automatic metering and discharging machine is used in conjunction with the label, the production batch of the product can be clearly identified through the label information, thereby achieving product quality traceability.
