Description

PLC CONTROL ALGORITHM IN ROUND CHANNEL MACHINE AND DEVELOPMENT IN THIS MACHINE

Technological Field:

The present invention relates to the PLC control algorithm and the development of the machine in the round channel machine, which is especially used in the development or production of a high diameter round channel.

Known State of the Technology:

Nowadays, the ventilation and air conditioning systems are used to transport and distribute the air which is used as the heat carrier fluid to the desired places in the most appropriate way by means of air ducts. Air ducts are processed in the air conditioning plant and the air brought to the desired comfort conditions is delivered to the places of use and the polluted air is thrown out at the places of use. Machines used for bending sheet metal in cold and cylindrical shape are called roller bending machines. They are manpowered and motorized types. Electrical and hand tools have been produced in various ways for the processing of sheet metal and to the desired dimensions. Electrical and hand tools have been produced in various ways for the processing of sheet metal and to the desired dimensions. By using these tools, the sheet metal part which is drawn in projects can be cut. In sheet metal work, the cutting process which is the stage after the measurement process is started. Cutting, is the process of dividing the materials into two according to the desired dimensions. According to the scope of the cutting process, it can be cut using hand shears, sleeve scissors and guillotine.

After the marking on the edge dimensions where the thin sheet parts will be joined to each other, special passages formed by bending and bending the work pieces separately and in various ways are called the latch. The clamps which are necessary for joining the two ends of the slab-cutting sheet are bent using the clamping machine. The shape of the clamp is removed from the machine and the shape of the clamp is checked by miter and by looking. If there is a disorder, it is connected to the machine and corrected by the rammer. Clamps are bent ready to be rolled. Cylinder machines are used to roll the plate.

In the roller machine, by means of the arm which moves the lower execution roller up and down, the plate is compressed. The top execution roller is fixed and one side can be removed from the machine to remove one side and the other side after removing the cylinder parts. The bending roller moves up and down to determine the diameter of the cylinder to be bent. The bending part is placed in the roller machine and the lower execution roller is tightened. The swiveling roller moves the execution roller until the desired diameter is reached. When the sheet is rolled, care must be taken to ensure that the clamp sections are not blocked by entering between the rollers. A fully rounded shape should be obtained by making the piece back several times in order to make the piece completely rounded.

When the anchor parts of the sheet are touched together, the workpiece is taken by removing the top execution roller of the roller machine. The clamp locations of the cylinder part removed from the roller machine are combined. To prevent the anchor from pulling on an anvil, the clamp is pounded with a rammer and the cylinder channel is made. If there is any deterioration in the ovality, the workpiece placed in the machine is brought back to the desired shape by removing the upper execution roller from the cylinder machine. The same process is done on this pipe by making support legs on both ends of the large diameter pipe if there is no cylinder anvil.

The cylindrical tubular sheet is made of sheet material and the structures of the ducts are kept in a smooth circle and the rims are shaped outward. This process is called cord drawing and machine is called cord machine. The cord machine makes this process with the rollers. Depending on the job to be done a wide variety of reels are needed. Cord pulling process is installed in the cord machine by selecting the appropriate spool. Adjusting the distance of the support piece adjusts the cord distance. The thrusters are tightened so that the settings do not deteriorate. The upper rollers are fixed to each other by the roller shift lever. The channel to be drawn is placed between the rollers and the top roller tightening screw is tightened. Then the sleeve is turned into the inserted channel and cord being pulled.

In the patent application US6000261,“Portable spiral pipe manufacturing machine and production method” is described. The invention is a machine for forming pipes which can be easily transported to various positions.

In the patent application US8522587, "Machine used in the production of spiral ventilation pipes" is described. There is a common workbench of a spiral tube manufacturing device comprising a winding impeller around the circumference of a metal plate element. There is a wave bending device that cuts the metal plate element fed from the opening machine to a straight line and forms a single folded portion and a double folded portion on both sides of the fluctuating and cut metal plate element. It is mentioned that the metal plate element fed from the wave bending apparatus has a ball wheel which bends upwardly the protruding wave portions. The patent application US20120103046 Al discloses a "spiral tube forming machine". In US6460236 Bl publication, "An apparatus for ventilation pipes" is described. In GB959889, the application "Tubing machine" is described.

In the aforementioned patent / utility model applications, spiral pipe manufacturing machines are mentioned. The diameters of the spiral pipes to be produced in said systems cannot be adjusted in a practical way. However, production is not easy and problems arise during manufacturing. Especially in the production of round ducts to be produced in different diameters, the diameter adjustment takes time. The biggest problem of the existing systems is the installation of the new mold. This situation requires both extra time and labor force to slow down the production speed. These applications developed semi-automatic systems by eliminating mold change. Because these systems need operator labor, they have not been able to provide convenience. The patent application US2008/0000280A1 discloses a "Spiral tube machine". In this application, the diameter adjustment is made by using a pneumatic or actuator or hydraulic motor. This saves time by eliminating the problem of installing new mold on the machine for every new diameter found in existing systems. However, this system is also controlled by the operator by adjusting the diameter. Therefore, the creation of the new diameter setting cannot be performed fully automatically. In the light of this information, it is possible to adjust the diameter of the system more quickly. The product of the present invention has not been able to fully meet the need of the sector. As a result, there is a need for a new technology which is simple to use and does not take time to manufacture, which can be used in the diameter adjustment unit, which can overcome the above mentioned disadvantages, and servo motor in the plate opening angle adjustment unit, which can be controlled by PLC and quickly to adjust the diameter.

Definition of the Invention:

The present invention is a PLC control algorithm on a round channel machine which can overcome the aforementioned disadvantages and the development of this machine. It is a new technology which is simple to use and does not take time to manufacture, which allows the adjustment of the diameter quickly by adjusting the diameter of the diameter adjustment unit and the servo motor in the plate input angle adjustment unit, controlled by PLC. The diameter value to be produced by the PLC control unit together with the product of the present invention is selected from the control panel. Based on this selection process, the diameter adjustment unit drives are opened automatically. This process is synchronized with the driver in the hair input angle adjustment unit by moving to the defined position becomes ready for production. The product of the present invention is ready in a short time for the size of each diameter to be produced with this feature. In existing systems, the time losses of the molds being changed or ready for production by pneumatic, hydraulic and actuator motor are completely eliminated. The product of the present invention has created a significant advantage by minimizing the need for both time and labor force.

With the help of spot welding machine in the product of the present invention; when the sheet is finished, new sheet is installed. In this step, the starting point of the new sheet is overlapped by the point which is close to the exit of the previous sheet (ie with the point where the previous sheet ends). Thus, the continuity of the withdrawal of the sheet is ensured during production. With the spot welding machine, the production continues without stopping for the new sheet without any need for re-entry and adjustment. Thus, the production speed was prevented and the production speed was increased.

In the patent application TR201410235 of the Applicant, the "Automatic Round Channel Machine with Servo System" is described. The applicant has found in his application that improvements to the algorithm of the PLC system are needed. In the light of this situation, by making improvements on the relation of servo motors with PLC system, it has completely automated the process of making the diameter adjustment in the production of round channel.

By the easy fixing of the components forming the invention, it is easy to install and the costs are low due to the short installation time. The invention also has a solid structure.

The algorithm steps of the product of the present invention are essentially as follows; The PLC control unit (K) has four diametrical servo motors (3.1) and one servo motor (4.1) signal to the servo motor (100) and the four diametrical servo motors (3.1) on the screw shafts (3.3) (200) and the linear servo motor (4.1) on the ball screw (4.4). and the angle servo motor (4.1) being moved circumferentially around the rack (4.4) (300) (Figure-8, Figure-9, Figure-l3).

The invention has an angle servo motor (4.1) which moves from the PLC control unit (K) simultaneously with the diameter servo motors (3.1) (Figure-6, Figure-8, Figure-9, Figure-l 1). The invention moves the angle servo motor (4.1) circumferentially about the roller opening unit (6) around the rack (4.4) (300) (Figure-9, Figure-l3). Together with the product of the present invention, four diameter servo motors (3.1) and one angle servo motor (4.1) move simultaneously to reference points by selecting the Go to reference (R) from the digital display on the PLC control unit (K) (Figure-6, Figure -8, Figure-9). In accordance with the diameter selected from the diameter list (C) on the digital display in the PLC control unit (K), the invention selects the command (P) from the digital display (K) in the PLC control unit to select the four diameter servo motors (3.1) and the angle of the servo motor (4.1) to move to points that correspond to the size of the selected diameter at the same time (Figure-6, Figure-8, Figure-9, Figure- 12). At the same time, the strip position command (S) is selected from the digital display on the PLC control unit (S), and according to the diameter position values, the diameter belt adjustment unit (9) is opened to the size of the diameter (Figure-4, Figure-6).

A main drive motor (1), a hydraulic unit (2), a servo motorized diameter adjustment unit (3), positioned to be on the side of the hydraulic unit (2), a servo motorized hair entry angle adjustment unit positioned at the rear side of the system (4) ), the round channel machine (5), which includes the main frame (5) on the system, the roller opening unit (6) associated with the servo motor sheet metal entry angle adjustment unit (4) and the diameter belt adjustment unit (9) associated with the servo motor diameter adjustment unit (3). M), with the development made; hand wheel (8) with four diameter servo motors (7), (3.1) and one angle servo motor (4.1), manually positioned between the roll- opening machine (6) and the servo-motorized diameter adjustment unit (3). The belt- loop adjustment unit (9) to be adjusted according to the precise diameter of the belt consists of the adjustment button (Figure-l, Figure-2, Figure-3, Figure-4, Figure-5).

The invention has a spot welding machine (7) which provides the end point of the sheet to be finished in the roll-opening machine (6) and the starting part of the sheet roll to be inserted to the upper part of the sheet (Figure-2, Figure-6). With the product according to the invention, the last diameter is recorded by selecting the command (G) from the digital display on the PLC control unit (G) in the machine's memory by making changes by the hand wheel (8) (Figure-6, Figure-l2). Detailed Description of the Invention:

The components of the invention are basically; main drive motor (1), hydraulic unit (2), servo-motorized diameter adjustment unit (3), servo motorized hair input angle adjustment unit (4), main chassis (5), roll opening unit (6), spot welding machine ( 7), hand wheel (8), diameter belt adjustment unit (9), belt adjustment button (10) and PLC control unit (K) (Figure-l, Figure-2, Figure-3, Figure-4, Figure- 5). All these parts form the round channel machine (M). The commands on the digital display of the PLC control unit (K) are basically; diameter list (C), axis list (E), update command (G), go to position (P), go to reference (R) and lane position command (S) (Figure-6, Figure-l2).

Axis list (E); X, Y, Z, A and B axes. Axis letters can also be differentiated according to firms. The axis list (E) shows the axis position of the drives and the position where the diameter should be for the selected operation (Figure- 12). Diameter list (C) allows selecting the size of the diameter to be produced and how many pieces to produce (Figure-l2). It can be changed by the operator to be manufactured and can be updated with the update command (G) after replacement (Figure-l2).

The servo motor diameter adjustment unit (3) in the product of the present invention consists of five basic parts (Figure-9). These parts are the diameter servo motor (3.1), pulley (3.2), ball screw (3.3), mechanism (3.4) and support pulley (3.5) (Figure-9). The hair opening angle adjustment unit (4) of the servo motor in the product of the present invention consists of four basic parts (Figure-8). These are the angle servo motor (4.1), the combined gear unit group (4.2), the pinion gear (4.3) and the rack (4.4) (Figure-8).

The operation of the product of the present invention is as follows; firstly, the machine is energized. The system is controlled by the signals sent to the drives by the PLC control unit (K) (Figure-6). If there is an error, the signals sent by the PLC control unit (K) to the digital display indicate the cause of the error (Figure-l 1). These errors are corrected by the operator If there is no error, the PLC control unit (K) switches to the operating mode by sending signals to the system's drivers. By selecting the Go to reference command (R) on the digital display by the operator, the PLC control unit (K) enables the axes to move to the reference points by sending four located diameter servo motors (3.1) and one current angle servo motor (4.1) (Figure-9, Figure-l l). This process includes four available diameter servo motors (3.1) and one located angle servo motor (4.1), each driver has their own axis in the opposite direction of the switch is seen as a point of reference to the movement of the switch by taking all the drivers when they go to the reference point PLC it sends the signal to the control unit (K) (Figure-8, Figure-9). After this step, the reference points are used to cover these points for each process until the machine is de- energized.

At this stage, the operator selects the diameter of the product to be produced via the digital display from the diameter list (C). The four diameter servo motors (3.1) that move the axes according to the selected diameter and one angle servo motor (4.1) send signals to the drives (Figure-8, Figure-9, Figure-l2). On the incoming signal, the PLC control unit (K) selects the drive position adjustment unit (3) and the servo motor input angle adjustment units (4) to the predefined diameter positions by selecting the go-to- position command (P) according to the predefined diameter position values. (Figure-8, Figure-9, Figure-l2). By simultaneously selecting the strip position command (S), the diameter zone adjustment unit (9) is also opened to the diameter to be treated (Figure-4, Figure-l2). This is done by the sensor and belt motor associated with the diameter control unit (9) and the signal from the PLC control unit (K) (Figure-4). The diameter band counts the holes on the adjustment unit (9) according to the diameter of the sensor (Figure 4). Based on this counting process, the sensor moves the belt motor. In addition, it is possible to adjust the diameters that are sensitive with the arm on the belt motor. The diameter belt adjustment unit (9) can also be moved by the belt adjustment knob (10) (Figure-4, Figure- 10). The operation of the servo motor diameter adjustment unit (3) is as follows; The signal from the PLC control unit (K) to the driver of the four diameter servo motor (3.1) drives these motors and moves the actuator (3.4) up and down by rotating the screw shaft (3.3) with the action taken by the pulley (3.2) driven from it. Figure-9). With its movement, it fixes the support roller (3.5) fixed to it in the diameter adjustment position defined in the PLC control unit (K) system (Figure-9). This diameter of the PLC control unit (K), the center of the four axis to apply this process to all axes at the same time (Figure-9).

The operation of the steel entry angle adjustment unit (4) is as follows; when the servo motor diameter adjustment unit (3) starts with the order taken from the PLC control unit (K), the servo motorized metal sheet angle adjustment unit (4) is also moved by the signal from the PLC control unit (K) to the angle servo motor (4.1) drive and the combined drive group (4.2) is driven by it (Figure-8). The combined gear unit group (4.2) allows it to move the pinion gear (4.3) fixed to it on its rack (4.4) fixed to the main frame (5) by turning it about its axis (Figure-8). Thus, the round channel to be produced by moving the roll opener unit (6) fixed to the servo motorized sheet opening angle adjustment unit (4) is fixed on the main frame (5) by bringing it to the position suitable to the angle of the diameter defined in the PLC control unit (K) for the tape sheet (5) (Figure-8).

If the operator deems it necessary, he / she can selectively change the position of the machine by selecting the command from the digital display (G) by changing the hand wheel (8) in the positions (Figure-3, Figure-l2). When the servo-motorized diameter adjustment unit (3) and the servo motorized sheet metal input angle adjustment unit (4) are positioned according to the selected diameter, the information is sent to the PLC control unit (K) from the drives (Figure-8, Figure-9, Figure-l l). The PLC control unit (K) starts the production of the product by pressing the operator to start mode in PLC control unit (K) after the machine is ready (Figure-l 1).

The operation of the spot welding machine (7) is as follows; when the sheet is finished, new sheet is installed. In this step, the starting point of the new sheet is overlapped by the point near the exit of the previous sheet (i.e. with the point where the previous sheet ends) (Figure-2). Thus, the continuity of the withdrawal of the sheet is ensured during production. With the spot welding machine (7), the production continues without stopping for the new sheet without the need for re-entry and adjustment (Figure-2).
