Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco equipment technology, specifically relating to a small-material batching and filling line. Background Technology
[0002] Tobacco additives, including flavorings and sugars, are used to improve the flavor of tobacco and reduce its irritation during combustion. In tobacco production, various tobacco additives need to be mixed in a mixing tank before being packaged into filling containers according to usage requirements. Specific usage needs generally fall into two categories: production line additives and externally sold additives. Production line additives require precise weight control to meet production line requirements and avoid affecting product quality. Externally sold additives do not have the same weight control precision requirements. Furthermore, externally sold additives are generally packaged in large containers, while production line additives are packaged in small containers. The measuring scales used for large and small containers also have different ranges and measurement accuracies. Guided by these usage needs, existing mixing tanks require frequent changes of different measuring scales and adjustments to filling heights (due to the different heights of the large and small containers) when filling large and small containers separately. This adds unnecessary work (including adjusting the position of the measuring scale and zeroing it), leading to reduced filling efficiency. Utility Model Content
[0003] This utility model provides a small-material separate barrel filling line to solve the technical problem of reduced filling efficiency caused by the need to change the corresponding weighing scale during the filling process of small barrels and large barrels in the existing mixing tank.
[0004] This utility model includes:
[0005] frame;
[0006] A three-axis robotic arm is mounted on the frame, and the end of the three-axis robotic arm is also provided with a rotating gripper.
[0007] At least one raw material barrel lifting device is located on one side of the frame;
[0008] At least one mixing tank is located on the other side within the frame;
[0009] The bottom of the mixing tank is provided with two drain ports, and a small bucket station and a large bucket station are located directly below the two drain ports.
[0010] The small bucket station is equipped with a first weighing scale, and the large bucket station is equipped with a second weighing scale. The first weighing scale is used to place and weigh the small bucket, and the second weighing scale is used to place and weigh the large bucket.
[0011] The mixing tank of this invention can simultaneously or separately fill large and small containers with small materials.
[0012] Furthermore: the drain outlet is a dispensing valve, and the dispensing valve is connected to an extension pipe;
[0013] The two extension pipes are respectively connected to the bottom of the mixing tank, or the two extension pipes are connected in parallel to the main pipeline and connected to the bottom of the mixing tank through the main pipeline. The beneficial effect of this step is that by extending the distance between the two drain ports through the extension pipes, interference between the large tank station and the small tank station can be avoided.
[0014] Furthermore: The measuring platform of the first weighing scale is provided with a limiting groove, which is adapted to the small bucket. The beneficial effect of this step is that the limiting groove ensures that the inlet of the small bucket is aligned with the drain outlet above.
[0015] Furthermore: the limiting groove is either protruding or recessed. The beneficial effect of this step is that the protruding or recessed type can be selected according to the equipment used to convey and transfer the small barrel.
[0016] Furthermore: the three-axis robotic arm includes a pair of parallel crossbeams, which are located at the top of the frame;
[0017] It also includes longitudinal beams, which are movably mounted on a pair of the transverse beams;
[0018] The longitudinal beam is provided with a sliding block that can move horizontally, and the sliding block is provided with a sliding rod that can move vertically. The bottom of the sliding rod is provided with a rotating gripper. The beneficial effect of this step is that the raw material barrel on the lifting device is grabbed by the three-axis robotic arm and the raw material is poured into the mixing tank.
[0019] Furthermore, since the volumes of the various mixing tanks are different, the beneficial effect of this step is that a suitable mixing tank can be selected according to the required amount of small materials.
[0020] Furthermore, each of the mixing tanks is provided with a filling port on its top surface, and each filling port is provided with a cover that can be opened and closed. The beneficial effect of this step is that the cover enables automated control and reduces manual operation.
[0021] The beneficial effects of this utility model are:
[0022] This application provides at least two drain outlets and corresponding workstations at the bottom of the mixing tank, enabling filling at different workstations without the need to change the weighing scale and workstations, thus improving filling efficiency. Attached Figure Description

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0034] This application implements, for example Figures 1-5 As shown, a small-material bin filling line is provided, which can fill small and large bins simultaneously or separately without changing the filling position and weighing scale, thus improving filling efficiency.
[0035] This utility model includes:
[0036] Framework 1;
[0037] A three-axis robotic arm 2 is mounted on the frame 1, and a rotating gripper 25 is provided at the end of the three-axis robotic arm 2.
[0038] At least one raw material barrel lifting device 3 is provided on one side of the frame 1;
[0039] At least one mixing tank 4 is located on the other side within the frame 1;
[0040] The bottom of the mixing tank 4 is provided with two drain ports, and directly below the two drain ports are a small bucket station 5 and a large bucket station 6.
[0041] The small bucket station 5 is equipped with a first weighing scale, and the large bucket station 6 is equipped with a second weighing scale. The first weighing scale is used to place and weigh the small bucket, and the second weighing scale is used to place and weigh the large bucket (the second weighing scale is not shown in the figure). The weight of the small material in the small bucket and the large bucket is weighed by the weighing scale to achieve the purpose of controlling the filling volume.
[0042] This invention utilizes an automatic raw material feeding device or manual feeding to feed raw material barrels onto a raw material barrel lifting device 3. The lifting device 3 raises the barrels to a height that a three-axis robotic arm 2 can grip. After gripping the barrels, the robotic arm 2 moves in three dimensions, aligning the barrels with the filling port of the mixing tank 4. The rotating jaws 25 then pour the raw materials from the barrels into the filling port. The mixing tank 4 then mixes the raw materials to form small batches (composed of several raw materials). Finally, the mixing tank 4 can simultaneously or separately fill large and small barrels with these small batches. In this configuration, regardless of whether the mixing tank 4 is filling small or large barrels, there is no need to change the filling position, switch the weighing scale, or adjust the scale, thus improving filling efficiency.
[0043] Generally, the small barrels are used for production on our own production line, and the filling volume of a single barrel is small and the filling time is short. Therefore, an automatic loading and unloading device will be set between the production line and this utility model. The small barrels are sold externally, and the filling volume of a single barrel is large and the filling time is long. Therefore, the large barrels will be produced by manual loading and unloading.
[0044] In addition, a weighing device is also installed under the support of the mixing tank 4 to weigh the total weight of the mixing tank 4 and the small materials inside, so as to determine whether the capacity of the small materials inside the mixing tank 4 has reached the maximum limit.
[0045] Based on the above, the filling control methods for the mixing tank 4 and the small and large containers can be divided into several types. One is the individual control method, which involves separately detecting the weight of each component in the mixing tank 4, small container, and large container, determining the remaining material in each, and then controlling whether to add raw materials to the mixing tank 4 and continue filling the small and / or large containers based on the remaining material data. Another is the linkage control method, which involves subtracting the weight of the small container from the weight of the mixing tank 4 to obtain the weight of the large container, and then implementing linkage control. Relatively speaking, the advantage of this control method is that it can reduce the need for weighing the large containers, but the disadvantage is that the control program is complex. In addition to the above control methods, other control methods may also be used.
[0046] In one embodiment, the drain outlet is a dispensing valve, which can accurately control the flow rate and on / off state of the small material, and the dispensing valve is connected to an extension pipe 41;
[0047] The two extension pipes 41 are respectively connected to the bottom of the mixing tank 4, or the two extension pipes 41 are connected in parallel to the main pipeline and connected to the bottom of the mixing tank 4 through the main pipeline;
[0048] In this embodiment, it is preferable to connect two extension pipes 41 in parallel to the main pipeline, and then connect the main pipeline to the bottom of the mixing tank 4. The extension pipes 41 can be connected to the main pipeline in the form of a T-shaped pipe. The reason for adopting the above method is that the bottom of the general mixing tank 4 is conical (to generate a potential energy difference at the bottom of the viscous material, thereby improving its fluidity). The main pipeline is connected to the lowest point of the conical bottom, which facilitates the flow of the material.
[0049] Then, the distance between the two drain ports is increased by extending the extension pipe 41 to avoid interference between the large barrel station 6 and the small barrel station 5; especially when the small barrel station 5 is equipped with an automatic loading and unloading device.
[0050] Based on the above technical solution, a limiting groove is provided on the measuring platform of the first weighing scale, and the limiting groove is adapted to the small bucket;
[0051] Regardless of whether the small buckets at station 5 are handled by an automatic loading / unloading device or manually, the small volume of the buckets dictates a short filling time and a high frequency of bucket replacement. Therefore, it is necessary to improve the efficiency of positioning the buckets under the drain outlet. Slow positioning will severely impact filling efficiency. Thus, a limiting groove is needed to ensure that the bucket inlet aligns with the drain outlet above.
[0052] Based on the above technical solutions, the limiting groove can be either protruding or recessed. Among the protruding and recessed limiting grooves, the setting method of the recessed limiting groove is relatively simple. It is only necessary to ensure that the shape of the recessed groove is consistent with the bottom shape of the small bucket and that there is a certain depth. However, the setting method of the protruding limiting groove is more diverse, such as three-sided surrounding (three sides are attached to the side wall of the small bucket) or four-sided surrounding (four sides are attached to the side wall of the small bucket). In the three-sided surrounding structure, the small bucket can be pushed in from the open, and in the four-sided surrounding structure, the small bucket is inserted from the top. As for the baffle that constitutes the three-sided or four-sided surrounding structure, it can be set with a flat plate, crossbar, or other structure. The specific form of the limiting groove can be selected as protruding or recessed according to the equipment for conveying and transferring the small bucket.
[0053] In one embodiment, the three-axis robotic arm 2 includes a pair of parallel crossbeams 21, the crossbeams 21 being disposed on the top of the frame 1;
[0054] It also includes a longitudinal beam 22, which is movably mounted on a pair of cross beams 21. In this embodiment, the longitudinal beam 22 is selected as a frame structure to improve stability.
[0055] The longitudinal beam 22 is provided with a sliding block 23 for translation, and the sliding block 23 is provided with a sliding rod 24 for vertical movement. The bottom of the sliding rod 24 is provided with a rotating gripper 25. The raw material barrel on the raw material barrel lifting device 3 is grabbed by the three-dimensional movement and rotation functions of the three-axis robotic arm 2 and the raw material is poured into the mixing tank 4.
[0056] In one embodiment, the several mixing tanks 4 have different volumes, and a suitable mixing tank 4 can be selected according to the required amount of small materials. This avoids using large tanks to mix small amounts of small materials, thus reducing energy waste.
[0057] In one embodiment, each of the mixing tanks 4 is provided with a filling port on its top surface. Each filling port is provided with a cover plate 42 that can be opened and closed. The cover plate 42 can be automatically controlled by a linear reciprocating motion mechanism such as a cylinder or an electric push rod, thereby reducing manual operation.
[0058] This utility model can be combined with an automated control program to control the feeding and discharging of raw material barrels and the pouring into the mixing tank 4, and the simultaneous or separate filling of small barrel station 5 and large barrel station 6 by the mixing tank 4. This not only saves unnecessary preparation work such as changing the weighing scale and adjusting the filling height, thus improving filling efficiency, but also has room for improvement in subsequent automated control.
