DETAILED DESCRIPTION OF THE INVENTION
[0052] In this detailed description, preferred embodiments of the wheeled military land vehicle assembly/disassembly automation system are described only for a better understanding of the subject and without any limiting effects.
[0053] In
[0054] The body mounting apparatus (111) has been specially designed to safely fix the military vehicle body (700) to be mounted/disassembled to the towers (100, 150) by using the PLC system (400) controlled main mounting body lock pins (112). Here, there are pin slots/lugs on the mounting body (700) where the pins will locate; the pins (112) provide safely locking by entering these lug slots. The locking takes place not mechanically (without man power) but completely by PLC System (400) controlled (automatic) pneumatic system.
[0055] The vertical movement system (113) shown in
[0056] When the towers (100, 150) reach their desired position (on the X and Y axis) on the rail (500), the PLC system (400) provides the ground lock system (114) shown in
[0057] The vertical movement lock system (119) shown in
[0058] On the tower (100, 150), there is an area scanner sensor (130) mounted with standard connectors and shown in
[0059] The tower horizontal movement system (133) that allows the drive tower (100) to move to the desired position around the program by moving on the anchor rail (500) on the X axis of the slave tower (150) with the control of the PLC system (400) is shown in
[0060] The PLC (Programmable Logical Controller) system (400) is the central control and management unit that control all moving elements and safety systems within the program limits within the automation system. It has its own database and is programmable. The vehicle body (700) and work piece (800) information (size, weight, mounting points, mounting coordinates, etc.) to be reassembled/disassembled to the PLC system (400) can be predefined via the control panel (300). From the information entered in the database, before the assembly/disassembly, the vehicle body (700) type and work piece (800) type are selected on the control panel (300), and the process steps predefined in the program are performed automatically by the PLC system (400). It is the automation system that provides all the inspection and control of the tower systems (100, 150) and automatically guided device (600). All movements within the automation cell (900) are automatically inspected and controlled by PLC system (400). It has a wireless communication infrastructure. All the sensors and switches on the system provide data flow to the PLC system control (400), and by this data, the positions of the towers (100, 150) and automatically guided vehicle (600) (on the X, Y and Z axes), all safety pins and warning system are controlled. Also, the PLC system control (400) unit instantly transmits the information about the status of the system within the mounting cell (900) from the screen on the control panel (300) by evaluating the data received from the sensors and switches. By controlling the system and safety limits (area information, carrying capacity, vehicle and subsystem information) predetermined to the PLC system (400) control as the real time by the logical controller, when a situation against to the work safety occurs, the system has the infrastructure to end the operation steps in a controlled and safe manner by performing audible and visual warnings via the warning system (140, 603) and via the screen (300). The information recorded in the database of the PLC system (400) has a flexible structure that can be changed, updated, added and removed at any time by means of the user interface and it can be improved.

[0073] The working principle (operation steps) of the assembly/disassembly automation system is as follows:
[0074] The technical information (size, weight, mounting points, working height, mounting coordinates, etc.) of the main body (700) and work piece (800) to be processed on the database of PLC (400) system are predefined to the system on the control panel (300). These data are stored in the database for the later use.
[0075] The operator selects the type of vehicle body (700) and subsystem (800) (axle complex type, suspension type, power group type, etc.) to be processed (assembly/disassembly) on the control panel (300) that has been predefined to the system.
[0076] The PLC system (400) activates the tower movement systems (133) and automatically brings the towers (100, 150) to the most suitable position on the rail (500) for the body (700) mounting on the X and Y axis. This process can also be performed manually by the operator by selecting the tower manual mode on the control panel (300) and using the direction buttons on the screen.
[0077] Safety system: The tower (100, 150) moved on the rail (500) apart from the program stops safely based on the tower stopper (510) when the rail (500) reaches the border point.
[0078] In both methods, when the vehicle body (700) reaches the programmed position, the safety switches (117) send a signal to the PLC system (400) and the tower ground lock system (114) automatically positions the towers (100, 150) by fixing them.
[0079] Safety system: The movements given from the control panel (300) while the towers (100,150) are being adjusted according to the type/variant (measures) are limited with the switches (117). The tower ground lock system (114) will not be activated before the switches (117) are activated. In addition, the vehicle body (700) cannot be connected to the towers (100, 150) and the tower vertical movement system (113) cannot be commanded without the drive (100) and the slave tower (150) ground locking system (114) being activated.
[0080] Simultaneously with the activation of the ground locking system (114), the vertical movement system (113) of the tower activates and brings the mounting body apparatus (111) to the most appropriate position on the Z axis where the vehicle body (700) can be connected according to the operator. In this process, if desired by the operator, the manual mode can be selected on the control panel (300) and manually by using the direction buttons on the screen.
[0081] The vehicle body (700) is placed on the mounting apparatus (111) on the towers (100, 150). When the existence/absence sensor (131) detects the vehicle body (700), the PLC system (400) controlled main mounting body lock pins (112) automatically become active and fix the vehicle body (700) to the mounting apparatus (111). During the locking, the lock pins (112) trigger the lock switch (132) and transmit the information whether the locks are activated or not to the PLC (400) system.
[0082] Safety system: When the vehicle body (700) is placed on the towers (100,150), the main body lock pins (112) do not work if the existence/absence sensors (131) do not become active. In addition, the towers (100, 150) cannot be moved until the safety switches (132) are activated, that is, the locking process is performed safely.
[0083] Before the locking is performed safely, the vehicle body (700) is automatically brought to the pre-programmed assembly/disassembly height with the vertical movement system (113) triggered by the PLC system (400) for the assembly of the subsystem (800).
[0084] Safety system: The safety lock system (123) is in a continuously locked position to keep the mounting apparatus (111) fixed to the tower during the operation. When the body mounting apparatus (111) is desired to be moved up/down on the Z axis from the PLC system (400) or the manual control panel (300), with the control of the PLC (400) system, the lock bolt (122) is automatically retracted and the mounting table (111) becomes free. It prevents the tower (100, 150) from leaving (falling) the mounting body (700) in case of failure.
[0085] This process can be performed manually by selecting the manual mode on the control panel (300) if desired by the operator and using the directional keys on the screen. However, in manual use, while being lifted with the servo movement (113), the synchronous lifting mode (both towers at the same time) should be selected, since the vehicle body is fixed on the towers (100, 150); asynchronous movement of the system towers (100, 150) is not allowed. When the vehicle body (700) reaches the desired position manually, the vertical movement lock system (119) is activated on the control panel (300) upon the instruction of the operator.
[0086] Safety system: For the optimum mounting height (on Z Axis) that the automatically guided vehicle (600) should be activated, the process continues until the “Height Sufficient” tab turns from red to green on the screen. Otherwise, the automatically guided vehicle (600) movement will not start.
[0087] When the lockings become active, the area scanning sensors (130) on the towers (100, 150) are automatically activated.
[0088] Safety system: The minimum and maximum movement of the mounting apparatus (111) on the towers (100, 150) on the Z axis are limited by the vertical movement safety switches (125). Also, the automatically guided vehicle (600) cannot be activated before the vehicle body (700) on the towers (100, 150) reaches a sufficient height for the assembly/disassembly.
[0089] When the vehicle body (700) is brought to the height programmed for the safe assembly/disassembly, the automatically guided vehicle (600) at the home (zero/start) point is automatically activated by the control of the vehicle PLC system (604). According to the type of work piece (800) to be mounted on the vehicle body (700), it automatically adjusts itself to the optimum height on the Z axis where the work piece (800) will be loaded on the vehicle (600). This process can also be performed manually with the control handle (601) on the vehicle (600).
[0090] While the automatic guided vehicle (600) is in the home (zero/start) position, the subsystem (800) to be assembled is placed on the upper plate complex (605) by centering it with the help of work piece positioning pins (612).
[0091] Safety system: The work piece (800) cannot be incorrectly placed on the top plate complex (605); the work piece positioning pins (612) will prevent this.
[0092] According to the type of work piece (800) to be assembled/disassembled, there is a manual jack system on the carrier plate (611) that enables the operator to position any structure of the subsystem according to the Z axis if necessary. (For example: In the axle complex assembly; it is used to lift/align the axle arms to the mounting slots.) There is no obligation to use.
[0093] With another method, the work piece (800) previously placed on the upper plate complex (605) is easily shifted onto the scissor platform complex (608) with the help of balls (615) and the upper plate centering pins (614) are placed on the platform (616) and fixed on the automatically guided vehicle (600) with the plate fixing apparatus (617).
[0094] Safety system: While the automatically guided vehicle (600) is in the home (zero/start) position, the operator controls that the upper plate centering pins (614) on the work piece carrier plate (611) are securely seated on the scissor platform complex (47), these pins (614) ensures that the work piece carrier plate (611) is in the fixed position.
[0095] The operator makes the process selection (these selection modes have been predefined to the system), where the X, Y and Z position (coordinate) record is located, through which the work piece (800) will be guided through the control panel (300).
[0096] By activating the upper car movement system (X Axis) (631) on the upper car complex (609) with the vehicle PLC control (604), it automatically enables the automatically guided vehicle (600) to reach to the X coordinate predetermined in the program with the subsystem (800).
[0097] The vehicle (600), which reaches the position determined in the X coordinate, again activates the hydraulic unit (646) of the vehicle PLC system (604) and applies a 60 mm stroke to the lower car complex (610) of the hydraulic cylinders (610) on the Z axis and cuts the contact of the upper car complex (609) with the ground. When the contact of the upper car complex (609) with the ground cuts, the vehicle (600) becomes movable on the Y axis on the lower car complex (610). This time, by activating the lower car movement system (Y Axis) (651) on the lower car complex (610) with the control of the PLC system (604), it automatically ensures that the automatically guided vehicle (600) reaches to the Y coordinate predetermined in the program together with the subsystem (800).
[0098] The movement of the automatically guided vehicle (600) on the X and Y axis can also be performed manually by using the vehicle control (601) if desired by the operator.
[0099] Safety system: The automatically guided vehicle (600) cannot collide with any obstacles that may appear in its way, when the area scanner sensors (606) encounter the obstacle; the PLC system (604) becomes active and ends the movement of the vehicle (600).
[0100] Immediately after the automatically guided vehicle (600) is positioned at the X and Y coordinates, simultaneously the PLC system control (604) activates the scissor structure movement motor (620) and the scissor movement starts automatically. The work piece (800) continues the Z movement on the scissor platform complex (608) and stops when it reaches the preadjusted final position.
[0101] Safety system: Automatically guided vehicle (600) cannot move the subsystem (800) to a position different from the position selected from the control panel, as required by the program. The encoders connected to the scissor structure movement motor (620), horizontal movement motors (X Axis) (632) and (Y Axis) (652) send the motor rotation direction, speed and rotation angle information to the vehicle PLC system (604) system in real time. The vehicle PLC system (604) processes this data and makes the necessary adjustments automatically.
[0102] Movement of the automatically guided vehicle (600) on the Z axis can also be performed manually by using the vehicle control (601) if desired by the operator.
[0103] Safety system: The vehicle PLC system (604) confirms the distance sensor (Z Axis) (628) that sees the main mounting body (700) on the tower (100, 150) where the lifting work will be on the Z axis.
[0104] When the automatically guided vehicle (600) reaches the position programmed on the Z axis, it takes its final position for the work piece (800) assembly. The operator reaches the step on the vehicle (600) to complete the assembly of the subsystem (800) ergonomically and completes the assembly operation by fixing the work piece (800) to the main vehicle body (700) using the connection bolts for the final assembly.
[0105] It commands the automatically guided vehicle (600) to go to its home position by the operator via the control panel (300) or via the vehicle control (604). The automatically guided vehicle (600) goes to the zero (home) point by applying the steps it performs on the Z, Y and Z axes for the assembly with the control of the vehicle PLC (604) system in reverse and takes the position for the second work piece (800) assembly.
[0106] Safety system: Automatically guided vehicle (600) ensures that it returns to its home position after the operation with the servo motors (620, 632 and 652), the limit switch (700) and the limit sensor Again safety system: When a situation against the work safety occurs during the manual or automatic operation, the system can be stopped safely by using the emergency stop buttons on the PLC system (400), the control panel (300) and the vehicle PLC system (604).
[0107] The PLC system (400) control provides a continuous flow of the data from the sensors and switches, and automatically informs the operator about the status of the system in all operation steps in an audio and video way. When an unsafe situation occurs, it automatically stops the system safely.
[0108] The scope of protection of this application is determined in the claims, and it is obvious that a person skilled in the art can set forth the innovation presented in the invention by using the similar configurations and/or apply this structure to other similar fields used in the related technique. Thus, it is apparent that such structures will be lack of exceeding the criteria of the innovation and especially the state of the art.
