Technical Field
The application relates to the technical field of measurement of specific variables, in particular to a slicing machine with a material detection function.
Background
With the development of technology, an automation means becomes reality in a plurality of industries, and provides conditions for improving productivity and efficiency. In general, the higher the degree of automation, the more significant the advantages it brings. If each process of production can be automated, the production line designed based on the process can obviously improve the production condition. However, industrial processes often involve multiple links, and the engagement between upstream and downstream places higher demands on the pipeline operation. For example, in the field of Chinese medicinal material production, the Chinese medicinal materials need to undergo sorting, slicing, drying, storage and other links. The Chinese medicinal materials in different batches have different water contents due to different collecting environments and different types of the medicinal materials, so that the subsequent drying process is also affected. If the drying time is insufficient, the moisture content of the product is high, which is unfavorable for storage. If the drying time is too long, the physical properties of the product may be affected, and the transportation and the maintenance of the drug effect may be affected. If a certain preparation can be made for a downstream drying process in a slicing link, the production line operation can be realized, and the product quality can be guaranteed.

The term "coupled" as used herein includes both direct and indirect coupling (coupling), unless otherwise indicated.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
The slicer of the present specification, as shown in fig. 1, includes a blade assembly, a moisture detection assembly, and a control assembly. The present specification has been made to design only a portion of the microtome for realizing the cutting function, the moisture detecting function, and the material transporting function, and as for other functions (e.g., an automatic shutdown function, a blade cleaning function, a blade protecting function, etc.) and an exterior design that the microtome needs to realize, in the related art, technical means that can be used to realize these functions are applicable to the present specification, as conditions allow.
Wherein the blade assembly comprises: a plurality of blades arranged in sequence; is configured to: when moving along the cutter direction, cutting the material, and after finishing cutting, moving along the opposite direction of the cutter direction for resetting. After reset, the relative position relationship between the blade and the material is shown in fig. 1. The dimension of the blade assembly in the direction of alignment is typically greater than the dimension of the material in that direction to ensure that the material does not have places where it cannot be cut. To achieve this, the number of blades included in the blade assembly may be determined based on actual production requirements. In an alternative embodiment of the present disclosure, the blade assemblies include adjacent blades that are equally spaced apart, and the distance between the blades is the target material size. The blade assemblies in this specification are of unitary construction at least when cutting is performed, and the blades in the blade assemblies act together when cutting is performed. In an alternative embodiment, the blade assembly further comprises a knife handle, and one end of each blade, which is not used for cutting, is connected with the knife handle, so that the knife handle is moved, and all the blades can be driven to move. If one blade fails, the blade can be independently disassembled to complete replacement. The same blade assembly comprises the same structural size of each blade so as to stabilize the cutting effect.
A moisture detection assembly comprising: the device comprises a detection unit, and a first probe and a second probe which are respectively connected with the detection unit. When cutting is executed, the blade assembly and the probe are integrally arranged, so that the probe moves along with the blade under the drive of the blade assembly, and one end of the probe can be inserted into a material to realize moisture detection. The first probe and the second probe are each configured to: inserting the cutter blade assembly into the material when the cutter blade assembly cuts the material so as to acquire data of the material representing moisture; the detection unit is configured to: and determining the moisture of the material based on the data acquired by the first probe and the second probe. In an alternative embodiment of the present disclosure, the moisture detection assembly is a moisture detection using halogen infrared moisture detection principles. Illustratively, a moisture detection product having a similar halogen infrared moisture detection principle, such as a halogen infrared moisture detector model H5216 (deke brand).
The relative positions of the probe and blade assembly are shown in fig. 1. The first probe is attached to one side of the middle blade in the middle of the arrangement sequence in the blade assembly, and the two positions are relatively compact. Considering that the material does not necessarily have a loose structure, the probe can not necessarily be inserted into the material, and how to detect the actual water content becomes a problem to be solved urgently. Particularly, for materials with higher water content or higher water holding capacity, water overflows at the material surface caused by cutting, at this time, the first probe can detect the overflowed water on the section, and the data detected by the first probe is likely to be slightly higher than the actual water content of the materials due to the extrusion of the blades to the materials. In an alternative embodiment of the present disclosure, to ensure accuracy of the detection as much as possible, the probe is processed into a needle-like structure toward one end of the material.
The second probe is arranged between the other side of the middle blade and the blade adjacent to the middle blade, the position is not affected by the water overflowed from cutting, and the detected result is irrelevant to the water holdup. If the material structure is loose, the probe can be inserted into the material, and the detection result of the second probe is more accurate. In addition, the second probe also does not have to be able to be inserted inside the material (influenced by properties of the material itself, such as toughness, dehydration rate, whether there is a cleaning process upstream) and possibly more moisture is detected on the surface of the material.
In some cases, the number of blades included in the blade assembly is even, there are two blades located in the middle of the blade assembly, and one of them is referred to as the middle blade in the present specification. In general, in order to ensure that materials can be uniformly cut, the materials need to be conveyed to the middle part of the blade assembly as much as possible, and then the parts on two sides of the materials can also be cut.
On the one hand, when the blade is driven to move downwards along the direction of the lower cutter, the probe is driven to be inserted into or props against the material, so that the detection of the moisture of the material is realized while the material is cut; on the other hand, the cutting positions of the first probe and the second probe relative to the blade are different, water overflows caused by partial defects of the materials caused by cutting can be detected by the probe, so that the water content in the materials possibly existing is higher, or the water holding capacity of the materials is higher, and factors which influence downstream drying can be detected.
The control assembly is respectively connected with the blade assembly and the moisture detection assembly; and the cutter is configured to control the cutter assembly to lower the cutter and control the feeding of the materials so that the cutting can be periodically performed, and after the cutting is finished, the materials are sent away under the control of the control assembly, and the uncut materials are conveyed to the cutting direction of the cutter again.
To achieve accurate detection, the detection unit in this specification is further configured to: the moisture content determined based on the data acquired by the first probe is used as first data; the moisture content determined based on the data acquired by the second probe is used as second data; in the case that the first data is larger than the second data (the possibility of the phenomenon that the water holding rate is higher, and the phenomenon that the second data deviates from the accurate data is likely to exist), weighting the second data by adopting preset weights to obtain target data, and enabling the target data not to be larger than the first data; the target data is used for representing the moisture content of the material; the preset weight is greater than 1, is determined based on the type of the material, and is positively correlated with the size of the material along the cutter-down direction.
According to the method, the weight is set for materials with different water holding capacities to weight the water content, so that the influence of the water holding capacity on the drying process is corrected, the drying effect is improved, and meanwhile, the process connection between the upstream and the downstream is guaranteed.
In an alternative embodiment of the present specification, in the case where the first data is not larger than the second data (indicating that there is less possibility of a phenomenon in which the water holding rate is high, the phenomenon in which the second data deviates from the accurate data is not so serious), the average value of the first data and the second data is taken as the target data. In a further alternative embodiment, in order to obtain more accurate results, the plurality of second probes are arranged along the extending direction of the blade, and the second data is an average value of data acquired by the plurality of second probes.
In order to further improve the detection accuracy, in a further alternative embodiment of the present specification, the moisture detection assembly further includes a pressure sensor. The pressure sensor is coupled to the blade assembly and configured to: and detecting the pressure caused by the material when the blade assembly performs cutting. If the material is brittle, the pressure will be smaller and the overflow caused by the blade extrusion will be less obvious. If the material is tough, the pressure will be larger, the overflow phenomenon caused by blade extrusion will be more obvious, and the water retention will have a larger influence on the detection result. The preset weight is positively correlated with the pressure.
In general, it is not possible for a microtome to cut only one type of material from beginning to end, and in the event that the material being cut changes, how to re-weight it. In an alternative embodiment of the present specification, the detection unit is further configured to: the detection unit is locally stored with a material coefficient table, and the material coefficient table is used for managing the corresponding relation between the type of the material and the preset material coefficient; the material coefficients are used to determine the weights. The material coefficients are determined empirically. The material coefficients can be determined experimentally for a new material by those skilled in the art.
In an alternative embodiment of the present disclosure, the duration of the specified time period is inversely related to the material coefficient of the material currently being cut and is not less than a preset duration. In particular operation, the preset time period may be set based on the cutting frequency of the blade assembly. Then, a target time length is determined, wherein the target time length is inversely related to the material coefficient of the material currently being cut. And then taking the sum of the preset time length and the target time length as the time length of the designated time period.
The microtome further includes an interaction component; the interaction component is connected with the moisture detection component; is configured to: and when the slicer is started, displaying the type of the material managed by the material coefficient table so as to determine the type of the material based on the selection of a user. The interaction component may also be used to input material coefficients.
In an alternative embodiment of the present disclosure, the microtome further comprises a conveyor assembly configured to: at least partially disposed in a lower knife direction of the knife assembly for conveying the material; the conveying component is connected with the moisture detection component so as to convey the cut materials with different moisture contents to a drying waiting area corresponding to the moisture contents based on the target data determined by the moisture detection component. For example, the drying waiting area includes a high moisture waiting area, a moisture waiting area, and a low moisture waiting area. The method comprises the steps of transmitting materials with higher moisture content indicated by target data to a high-moisture waiting area, transmitting materials with moderate moisture content indicated by the target data to a medium-moisture waiting area, and transmitting materials with lower moisture content indicated by the target data to a low-moisture waiting area.
Optionally, the conveyor assembly comprises tracks for carrying the material. In the related technical field, the technical means for conveying the materials to different areas can be realized, and the method is applicable to the specification under the condition of permission.
The transfer assembly may also be a conduit connecting upstream and downstream processes, and in an alternative embodiment of the present disclosure, an upstream process for cutting material may also include a material pretreatment process. Such as a peeling process. The dimension of the material processed by the upstream process in the direction of the lower cutter is not uniform, so that the dimension of some materials in the direction of the lower cutter is smaller, and the phenomenon that the probe cannot contact the material is likely to occur. Thus, in an alternative embodiment of the present description, the first probe and the second probe are movably arranged in the down direction. The control assembly is further configured to: if the detected first data and the detected second data are equal (there is a possibility that the probe cannot be sufficiently contacted with the material) within a specified time period (the duration of the specified time period is preset), the distance between the first probe and the second probe and the material is reduced, and the distance is not smaller than the minimum distance between the blade and the material. The adjustment may be effected by a motor drive.
When the moisture content of the material is detected, the phenomenon that residues or viscous juice of the material adhere to a probe caused by the factors such as the property of the material is unavoidable. To achieve cleaning of the probes, in an alternative embodiment of the present disclosure, the microtome further comprises a cleaning assembly having a porous or loose structure disposed around the first and second probes perpendicular to the direction of the knife, configured to: and cleaning one end of the first probe and the second probe towards the material when the first probe and the second probe move along the downward direction and the opposite direction of the downward direction. The relative positions of the cleaning assembly and probe are shown in fig. 2 when performing the cut. The relative positions of the probe and cleaning assembly when cleaning of the probe is performed are shown in fig. 3. The cleaning component and the blade component are arranged in a relatively fixed position. Optionally, the cleaning assembly comprises a sponge or cleaning gel.
Alternatively, cleaning may be performed periodically. Cleaning is only directed to the probe, and not the blade, and as the degree of cutting by the blade in contact with the material is greater than that of the probe, the possibility of adhering chips on the blade is greater than that of the probe, and if the blade is also cleaned, the cleaning assembly is possibly polluted, and the cleaning effect of the cleaning assembly is reduced. In the case where the cleaning agent is dissolved on the cleaning member, the cleaning agent may also contaminate the blade.
