Description

Machine tool intelligent management system

This creative department is related to CNC machine tools; in particular, it refers to a tool machine intelligent management system.

The known Computerized Numerical Control (CNC) refers to the computer-integrated control role of Computer Aided Design (CAD) and Computer Aided Manufacture (CAM), and further through Precisely edited precise instructions for automatic machine tool cutting.

The precise instruction refers to a process in which a machining program command is input into a memory of a numerical control system, compiled and calculated by a computer, and transmitted to a drive to drive the motor through a displacement control system to process the designed part. It contains moving instructions and other auxiliary commands that need to be used in the processing. The auxiliary commands include functional commands that have a certain meaning of actions or functions, which are composed of address codes (English letters) and two numbers. Common functional commands. Including G function (preparation function), M function (auxiliary function), T function (tool function), etc.

Knowing the application of CNC machine tools, practitioners first perform multiple tests and corrections on various types of tools used in cutting in the processing workshop, and hand-written or paper-cut tools for inspection and correction. The bar code method is used to write and classify the tool number, and then the detected and corrected tool is placed on the tool cart to be taken to the processing site. At the processing site, the practitioner places the tools on the tool cart one by one on the tool magazine of the CNC machine tool and arranges the tool holder in the tool holder. The "T15" in the machining program command is taken as an example. That means that the tool from the processing workshop to the processing site and numbered No. 15 should be placed in the tool magazine with the No. 15 tool holder. This allows the CNC machine tool to correctly access the tool when executing the machining program command. The workpiece is subjected to cutting.

However, in practice, the method of writing and classifying the tool by handwriting or paper bar code has the possibility of handwriting recognition or writing error, and the paper bar code is easily stained in the oily environment. Handwriting or paper bar code method is not perfect for the tool number writing and classification management.

In addition, during the process of removing the tool from the tool cart and placing it in the tool holder of the tool magazine, the practitioner may misplace the tool if it is not observed, for example, in the tool holder of the tool magazine No. 15 Placed as a tool that has been tested and corrected and programmed as No. 14, when the error is not found and enters the machining program, the magazine operates according to the machining program command and causes the No. 15 tool holder to be combined with the number of the tool holder When the No. 14 tool arrives at the position of the tool, the wrong No. 14 tool will be taken. In this case, the workpiece size after cutting will not be processed according to the machining requirements, and the tool will be damaged due to improper tool collision. Or the material to be processed is cracked and needs to be shut down to eliminate the problem, which will seriously delay the processing time.

In view of this, the purpose of this creation is to provide a machine tool intelligent management system that ensures that the tool can be correctly selected for processing.

In order to achieve the above objectives, an intelligent machine tool management system provided by the present invention includes a numerical control machine tool having a spindle, a tool magazine and a controller. The spindle is equipped with a tool at one end, the tool magazine accommodates a plurality of tools, and the controller has built-in processing program instructions. In addition, a plurality of electronic labels are respectively attached to a corresponding tool, and each electronic tag has a tool parameter corresponding to the tool, and a reader receives the electronic tag on the tool in the range in a non-contact manner. parameter.

The effect of this creation is to avoid the occurrence of processing errors caused by the practitioners misplaced the tool in the incorrect position of the tool holder.

The intelligent tool management system of the creation tool can effectively arrange and manage the tools used for machining, and can ensure that the tools can be correctly selected to prevent improper follow-up procedures, such as improper follow-up procedures. The wrong tool is processed, or it is the case that the tool improperly collides with the object to be processed. In order to explain the present invention more clearly, the management method of the preferred embodiment is described in detail in conjunction with the system architecture.

Referring to FIG. 1 , the intelligent management method of the machine tool according to the first preferred embodiment of the present invention mainly includes the steps of detecting the tool S1, storing the tool information S2, cutting the tool S3, cutting the tool information S4, and comparing the information S5, etc. Please refer to FIG. 2 to FIG. 5 again, and the description of each step and the equipment used in the implementation of the step is as follows.

In the inspection of the tool S1: Since the machine tool often needs to use a variety of different types and specifications of the tool during the machining process, the practitioner must prepare for the tool 1 that needs to be used during the machining process, including the tool 1 Measurement and setting. In practice, instruments commonly used to detect tool 1 such as tool setting device include measuring but not limited to tool length measurement and tool radius measurement, and setting is performed on the measured result. Further adjustments such as tool length correction, tool zero setting, tool offset value setting, etc., the measurement and setting results of the aforementioned tools are stored in the computer 3 in a parametric manner. It should be noted that the tool 1 in the foregoing detecting operation is often detected by being mounted to the tool holder 4; in addition, the detecting work of the tool 1 is commonly applied to a processing workshop, which refers to the task according to the task requirements. The work site plans a specific area, and the processing workshop of this embodiment refers to a place where a large number of tools and related testing instruments are stored therein.

In terms of storing the tool information S2: the practitioner will use the transmitter 5 (Transmitter) and the antenna (Antenna) (not shown) in the computer 3 and the Radio Frequency Identification System (RFID) in the processing shop. The tool parameters obtained by detecting the tool 1 and stored in the computer 3 are sent to the electronic tag 6 as an example of a read/write RFID tag in a non-contact manner, and the tool parameters include tool specifications and cutting parameters. And the rotational speed parameter and the like, and having a machining tool number that is not repeated, the electronic tag 6 is attached to a corresponding tool 1 by way of being coupled to the tool holder 4, and more specifically, stored in each electronic tag 6. The tool information is the detection result of the attached tool 1 and each electronic tag 6 has a recognition degree because it has a non-repeating machining tool number.

In the case of tool placement S3: After the practitioner prepares the tool for machining in the machining shop, the tool 1 should be placed together with the tool holder 4 on it to the tool holder of the tool magazine 7A of the CNC machine tool 7. In 7B, the tool 1 having the corresponding machining tool number is placed in the tool holder 7B in accordance with the number on the tool holder 7B. As shown in FIG. 5, the number of "1" to the number "21" is sequentially marked in the counterclockwise direction on the surface of the magazine 7A, which means that the magazine 7A can be used to place 21 tools 1 having different specifications. The tools are all on the shelves, indicating that they can enter the machining program. The aforementioned magazine 7A may be a disc magazine or a chain magazine capable of accommodating more tools.

In the tool information reading S4: When the practitioner opens the machining program through the operation panel 7D of the controller 7C of the numerical control machine tool 7, the tool 1 installed at one end (bottom end) of the spindle 7E is to be in accordance with the controller 7C. The machining program command is started to start high-speed rotation and displacement, and the workpiece 8 to be fixed on the table 7F is processed. Since a workpiece 8 usually needs to be processed by milling, cutting, drilling or threading to obtain a finished product, the tool 1 installed at one end of the spindle 7E is compiled according to the machining program instructions. If the execution of the tool number "T15" is executed, the end of the spindle 7E in the next machining program should be installed with the tool selected from the number "15" on the magazine 7A. 1. At the same time, the magazine 7A will be controlled to operate and transport the selected tool to the tool setting position. Before the selected tool is grasped, the reader 9 installed in the numerical control machine tool 7 will The tool parameters accompanying the electronic tag 6 attached to the tool 1 in the reading range are received in a non-contact manner. Taking the magazine 7A in Fig. 5 as an example, the position of the knife is located at the lowermost edge of the disk surface, and the reading range of the reader 9 refers to the distance from the reader 9 to the tool 1 at the position of the knife.

In the aspect of the comparison information S5: the controller 7C will automatically compare the machining tool number among the tool parameters received by the reader 9 with the execution tool number in the built-in machining program command, and compare the machining tool. When the number does not match the execution tool number, the control command is issued. Otherwise, if the machining tool number of the comparison matches the execution tool number, the controller 7C continues to execute the subsequent machining program according to the machining program command. For example, when the machining program command is executed to the executed execution tool number "T15", the magazine 7A is controlled to be operated to the tool holder 7B of the number "15" marked on the disk surface according to the machining program command. The tool 1 in the tool holder 7B comes together to the tool setting position, but the reader 9 receives the tool parameter in the electronic tag 6 attached to the tool 1 at the tool setting position but is a machining blade containing "T14". In the case of the number, the controller 7C issues a control command because the alignment is found to be mis-rotated. In an embodiment, the control command may be a stop command, so as to avoid the tool actually being programmed as "T14" being mistaken for the number " The tool of T15" is used for cutting, resulting in the workpiece size after cutting is not in line with expectations or improperly collided with the workpiece. The above situation occurs because the practitioner removes the tool from the processing workshop and places it in the tool holder of the tool magazine, which causes the tool position to be misplaced. It should be noted that the comparison between the machining tool number and the execution tool number is not limited to a digital comparison, and may be used for comparison by other code methods.

Therefore, the present tool receives the tool parameters in the electronic tag 6 attached to the tool 1 through the reader 9 and the comparison function of the controller 7C, and recognizes the selected tool before it is captured. Whether the tool position is misplaced further ensures that the tool is correctly selected for processing. In addition, the identification number of the tool is achieved by the electronic tag 6 having a non-repeating machining tool number, which improves the inconvenience caused by the handwriting or classification management of the tool by handwriting or paper bar code.

It is to be noted that, in addition to the control command, the controller 7C can be evenly displayed on the display screen 7G of the operation panel 7D, or can be reminded by sound or light. The function that the practitioner pays attention to so that the practitioner can eliminate the problem in time. Moreover, the controller 7C can also transmit instant information to a specific person having an electronic device that can read the information through a mobile application for monitoring.

The control commands in the above embodiments are used to control the shutdown. However, in other embodiments, the control commands may not be used to control the shutdown but are used as other controls, such as when the control command includes an execution knife among the machining program commands. When the number of the matching tool is matched, it can be used to control the operation of the tool magazine 7A and bring the correct tool 1 to the position of the tool. To achieve the foregoing objective, the intelligent management method of the machine tool according to the second preferred embodiment is provided in the present invention. The structure of the method of the first preferred embodiment is adjusted, as shown in FIG. 6, wherein after the tool is placed S3 and the tool information is read S4, the tool magazine 7A is operated in an indexing manner and read. The device 9 receives the tool parameters of the electronic tag 6 attached to all the tools 1 passing through the tool taking position one by one and transmits them to the controller 7C. The tool parameters include the tool number that is not repeated, and at the same time, the controller 7C The number on the tool holder 7B is linked and recorded with the machining tool number of the tool 1 stored in the tool holder 7B. For example, when the magazine 7A is operated to the number of the tool holder 7B. When "15" comes to the tool setting position, the machining tool number received by the reader 9 in the electronic tag 6 should be "T15" in the correct case, and the controller 7C will set the tool holder 7B number "15" and the tool. The machining tool No. "T15" of 1 generates the link and record. This step is defined as the tool and tool holder information collection S3-1.

When the practitioner finishes the tool and tool holder information collecting S3-1 operation and starts the numerical control machine tool 7 through the operation panel 7D to perform the machining program, the normal reader 9 receives the tool 1 located at the tool setting position. The number of the machining tool in the attached electronic tag 6 should match the number of the tool holder 7B which is also located at the tool setting position. However, if the practitioner removes the tool from the processing shop and places it in the tool holder of the tool magazine. During the process, if the tool position is misplaced, the machining tool number received by the reader 9 will be compared with the execution tool number in the machining program command after being compared by the controller 7C. At this time, the controller 7C The tool that finds the correct tool from the database is placed in the number of the tool holder, and the control command containing the machining tool number corresponding to the execution tool number is issued, and the tool magazine 7A is controlled with the shortest running stroke. The correct tool 1 is transported to the picking position so that the spindle 7E of the numerically controlled machine tool 7 can take the correct tool, and the aforementioned step of bringing the correct tool to the picking position is defined as the tool changing operation S6. At this point, the machining process can be continued without stopping the machine.

It can be seen from the above various embodiments that the management system for implementing the intelligent management method includes at least a numerical control machine tool 7, an electronic tag 6, and a reader 9, wherein the numerical control machine tool 7 further includes a spindle 7E, a tool magazine 7A, and a control. 7C; and if the management system further includes the transmitter 5, the management method will be more complete.

In addition, the present invention further provides an intelligent management method, which is applied to the machine tool system including the processing machine 10, the tool magazine 11 and the tool taking mechanism 12, wherein the processing machine 10 includes a spindle 10a and control. The tool 10b has a tool 1 mounted on one end of the spindle 10a, and a machining program command including a tool number is built in the controller 10b. The tool magazine 11 is independent of the processing machine 10 and has a plurality of tool holders 11a for accommodating various types. The tool has a non-repeating number for each tool position; and the tool taking mechanism 12 grabs the appropriate tool from the magazine 11 according to the machining program command.

Referring to FIG. 8 , the method includes steps of detecting a tool S1, storing tool information S2, tool placement S3, tool information reading S7, tool information connection and storage S8, and knife S9, wherein step S1 and step S2 are performed. The same as the above embodiment, the tool 1 in step S3 is placed in a different tool holder 11a of the magazine 11 belonging to the large-sized knife structure.

The method of the present embodiment refers to the tool information reading S7: the reader 9 whose front end is mounted by the manipulation moving mechanism (not shown) can read the respective tool holders 11a one by one in a non-contact manner. Store the tool parameters attached to the tool 1 with the electronic tag.

In the aspect of tool information connection and storage S8: when the reader 9 completes reading of each tool information, the controller 10b will automatically execute the tool number among the tool position, the tool number among the tool parameters, and the machining program command. Do information links and store them.

In terms of the tool S9: the tool taking mechanism 12 receives the execution tool number from the machining program command from the controller 10b, and further automatically grasps the tool 1 located in the tool magazine 11 and the tool number information in which the tool number information is connected. It should be noted that, in this step S9, the knife-taking mechanism 12 is based on the machining tool number in the electronic label on the tool, not the tool position, so that the tool position can be quickly found. Reduce time. The tool taking mechanism 12 brings the obtained tool to the processing machine 10 to continue the subsequent machining process. When the machining machine 10 includes the tool change arm 10c, the tool take-up mechanism 12 transfers the tool to the tool change arm 10c. The tool arm 10c is then exchanged with the tool on the main shaft 10a, and the tool removed from the main shaft 10c is placed in the empty tool position of the tool magazine 11 through the tool change arm 10c and the tool take-up mechanism 12.

Thereafter, step S7 and step S8 are restarted to wait for the execution of the next step S9. At this point, it is also possible to prevent the practitioner from mistaking the tool to misplace the tool at the incorrect position. It is also noted that, when based on the technology of the embodiment, it can be simultaneously applied to multiple tool machines and multiple sets of tool magazines for simultaneous use.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
