The device of the present invention can not only improve the production efficiency of a textile workshop, but also help eliminate safety hazards.
[0025] The operating process of the present invention is:
[0026] The automatic up-and-down shaft drive mechanism of the large cloth roll loom is controlled by the control system to control the action of each mechanism respectively. The control system controls the action of each part of the mechanism using existing technology, which will not be described in detail. After the automatic up-and-down shaft drive mechanism of the large cloth roll loom is powered on, the control system is automatically initialized. The control system resets various parameters to initial values. The controller in the control system queries the remaining battery power and resets the up-and-down shaft drive mechanism to its initial state. After the initialization is completed, if the remaining power is higher than the working allowable value, the wireless communication controller in the control system sends an online request to the main control center. When the wireless communication controller receives the permission instruction sent by the main control center, it successfully goes online. The specific actions are as follows:
[0027] Automatic cloth dropping, automatic transfer of full cloth rolls, automatic cloth unloading and automatic loom shaft change,
[0028] Automatic Cloth Dropping: When the central control center receives a signal indicating a loom is nearing completion, it sends a cloth drop command to the automatic loading and unloading shaft drive mechanism of the nearest large cloth roll loom, which has an empty shaft and is not fully loaded with cloth rolls. The cloth drop command includes the loom type and the location of the loom to be dropped. Upon receiving the cloth drop command, the vehicle 1 calculates the most appropriate route based on its own position and the location of the loom to be dropped, and moves along the route. When the vehicle 1 reaches the front of the loom, it decelerates and activates the relative position sensor between the vehicle 1 and the loom, guiding the vehicle 1 to align and move directly in front of the loom. When the automatic upper and lower shaft drive mechanism of the large cloth roll loom moves to the expected position, the wireless communication controller queries the expected movement trajectory and the lowering or upper shaft point of the clamping claw 13 of the upper and lower shaft mechanism 2 of the loom type through the loom type, and the wireless communication controller controls the upper and lower shaft mechanism 2 to move along the expected lowering shaft trajectory to the lowering shaft point. At this time, the clamping claw 13 hooks the end of the full cloth roll. After hooking the end of the full cloth roll, the telescopic electric cylinder 24 drives the finger 28 to rotate, and the outer side of the finger 28 contacts and clamps the full shaft.
[0029] After the upper and lower shaft mechanism 2 completes the shaft dropping action, the wireless communication controller controls the driving arm to continue to swing backward.
[0030] Automatic transfer of full cloth rolls: The automatic up-and-down shaft drive mechanism of the loom drives the full cloth roll to the front of the cloth inspection rack. The relative position sensor guides the trolley to align with the cloth inspection rack. The car body 1 reaches the cloth unloading position and is ready to unload the cloth.
[0031] Automatic cloth unloading action: The wireless communication controller controls the clamping claws 13 in the upper and lower shaft mechanism 2 to hook the full cloth roll, and the clamping claws 13 clamp the two ends of the extended shaft of the full cloth roll. Then the upper and lower shaft mechanism 2 unloads the full cloth roll to the cloth inspection buffer rack, and the loom automatically reverses the upper and lower shaft transfer vehicle 1 to the cloth unloading position, and the upper and lower shaft mechanism 2 returns to the initial position.
[0032] Automatic shaft changing of the loom: The wireless communication controller controls the clamping claw 13 in the upper and lower shaft mechanism 2 to hook the empty shaft. After hooking the empty shaft, the vehicle body 1 is moved to the shaft changing position. The empty shaft is connected to the loom through the arc-shaped moving trajectory of the clamping claw 13 in the upper and lower shaft mechanism 2, and the upper and lower shaft mechanism 2 completes the shaft changing action.
[0033] The present invention provides a hook device 16 on the clamping claw 13 of the hook of the upper and lower shaft mechanism 2, which drives the finger 28 to rotate the end of the clamping shaft 27 through the telescopic electric cylinder 24, ensuring the good stability of the full shaft and the empty shaft during the movement of the upper and lower shaft mechanism 2; the upper and lower shaft mechanism 2 is equipped with a pulling auxiliary device 14 on the driven swing arm 4, which provides a gradually increasing reverse force to the driving arm as the driving arm rotates during the extension of the clamping claw 13, thereby reducing the maximum driving torque required by the driving arm during the drop process, thereby reducing the power of the main motor 30 for the driving arm. , which is beneficial to prolonging the working time of the robot; the frame is installed with an arc slide rail 53, and the slider on the arc slide rail 53 is connected to the driving arm in the upper and lower shaft mechanism 2 through a connecting pin 55, which improves the lateral stability of the upper and lower shaft mechanism 2 during movement, and reduces the control complexity of the robot while realizing the functions of automatic cloth dropping, automatic cloth unloading, and automatic shaft changing. The present invention can realize the automatic cloth dropping, automatic transportation, automatic cloth unloading, and automatic shaft changing of large-diameter cloth rolls, and has excellent adaptability to full shafts with the same diameter of the extended shafts at both ends but different cloth roll diameters.
