Detailed Description
Referring to fig. 1 and 3, an embodiment of the present invention provides an automatic loading and unloading mechanism, which includes a drum clamp 200, a material frame 300, a positioning mechanism 400, a multi-axis mechanical arm 500, and a mechanical gripper module 600. Wherein the spool clamp 200 includes a clamp base 210, and a fixing jaw 220 and a first tape head jaw 230 provided on the clamp base 210, the fixing jaw 220 for fixing the spool to the clamp base 210, and the first tape head jaw 230 for holding the tape head of unwinding the roll. The material rack 300 is used for accommodating the roll jigs 200, and may accommodate a plurality of roll jigs 200. The positioning mechanism 400 is disposed at one side of the material frame 300, and is used for fixing the roll clamp 200, so as to facilitate the separation of the roll material from the roll clamp 200. The multi-axis mechanical arm 500 is disposed at one side of the material rack 300, and a mechanical gripper module 600 is disposed at the end of the multi-axis mechanical arm 500, so as to drive the mechanical gripper module 600 to move in space. The robot gripper unit 600 includes various facing spool gripping jaws 630 and gripper jaws 620, wherein the spool gripping jaws 630 are used to grip a spool of web material, and the spool may be removed from the spool gripper 200 or loaded onto the spool gripper 200. The spool clamping jaw 630 is further provided with a second tape head clamping jaw 633, and the second tape head clamping jaw 633 can clamp the spool while the spool clamping jaw 630 clamps the spool, and simultaneously, the tape head of the coiled material can be connected with the first tape head clamping jaw 230 of the spool clamp 200. The clamp jaws 620 are used to hold the spool clamp 200, remove the spool clamp 200 from the work stack 300, or replace the spool clamp 200 in the work stack 300.
According to the automatic feeding and discharging mechanism provided by the embodiment of the invention, the winding drum clamp 200 can clamp the tape head of the coiled material through the first tape head clamping jaw 230, and the winding drum of the coiled material is fixed on the bottom plate 210 through the fixing clamping jaw 220, so that the relative position between the winding drum and the unwound tape head is fixed, the coiled material is prevented from being dispersed after the tape head is unwound, and a large amount of coiled material with the tape head is stored on the material frame 300. While the robot gripper unit 600 includes gripper jaws 620 that grip the spool gripper 200 and spool jaws 630 that grip the spool, the spool and the spool gripper 200 may be transported. The material frame 300 side is provided with a positioning mechanism 400 for fixing the spool holder 200, facilitating the removal of the spool from the spool holder 200. The second head clamping jaw 633 capable of clamping the coil stock head is further arranged on the winding drum clamping jaw 630, the coil stock head which is unreeled can be connected from the winding drum clamp 200, and the unreeled head is sent to a specific mechanism on the equipment, so that the need of manually assisting in unreeling the coil stock head when the equipment is used for reel change is avoided. The automatic feeding and discharging mechanism can manually unwind the heads of a large number of coiled materials in advance, mount the unwound coiled materials on the reel clamp 200, and then mount the reel clamp 200 in the material frame 300. When the equipment operates, the equipment can automatically change the coiled material with the unwinding head onto the equipment under the condition of unattended operation for a long time, so that the full-automatic loading and unloading of the equipment are realized, a large number of operators are prevented from being arranged to take charge of the loading and unloading of the coiled material of each equipment, the automation degree of the equipment is improved, the number of the equipment which can be attended by a single person on a production line is improved, a certain manpower resource is liberated, and the manpower cost is reduced.
It will be appreciated that the automatic loading and unloading mechanism described above may be fixedly disposed on one side of the flyer mechanism of the apparatus. Or set up on AGV robot 100, as shown in fig. 1 and 2, can flow between many equipments automatically, and after the coil stock on the work or material rest 300 runs out, can remove to fixed manual feeding department automatically, the manual work will install the reel anchor clamps 200 of coil stock on the work or material rest 300 to retrieve the empty reel on the work or material rest 300, further improve the degree of automation in whole workshop. Preferably, the number of axes of the multi-axis mechanical arm 500 is preferably more than 4, and in this embodiment, the six-axis mechanical arm is used to drive the mechanical gripper module 600, so that the reel and the reel clamp 200 can be more flexibly taken and placed.
Referring to fig. 7, in some apparatuses, a roll of a coil stock needs to be fixed on a roll shaft of the apparatus by a specific roll gland 720 to prevent the roll from being separated from the shaft when rotating, and accordingly, when feeding and discharging the roll stock, the roll gland 720 on the shaft needs to be removed first to remove an empty roll from the shaft and to load a new roll stock. Referring to fig. 3 and 4, in some embodiments, the robotic gripper module 600 further includes a gland jaw 640 and a positioning camera 650, oriented differently from each other and from the spool jaw 630 and the clamp jaw 620. The gland jaws 640 are used to grip the spool gland 720 to facilitate removal of the spool gland 720 from the reel changer 700 of the apparatus. And because the position accuracy of dismouting reel gland 720 is higher in the position accuracy requirement of just dismouting reel, and the arm sets up on movable AGV robot, and the arm is not absolutely fixed for the position of equipment, needs location camera 650 to take a picture reel change carousel 700, fixes a position reel pivot and reel gland 720 on the carousel to ensure that multiaxis arm 500 can accurately dismantle reel gland 720 to the reel pivot. It can be appreciated that, under the condition that the automatic feeding and discharging mechanism is fixedly arranged at one side of the equipment and the repeated positioning accuracy of the mechanical arm and the driving device of the reel changing turntable 700 is high, the positioning camera 650 is not required to perform the pre-photographing positioning on the reel changing turntable 700 due to the relatively fixed position during the feeding and discharging of the reel changing.
It will be appreciated that the fixed jaw 220 and the first chuck jaw 230 on the spool clamp 200 preferably employ a passive clamping fixture that is clamped by the spring drive, since the spool clamp 200 requires a transfer, and an electric or pneumatic drive is inconvenient. The drum clamping jaw 630, the clamp clamping jaw 620, the second clamping jaw 633 and the clamping jaw on the mechanical clamping hand module 600 and the positioning mechanism 400 need to have the capability of actively opening and closing, and controllable clamping mechanisms such as an electric clamping jaw or a clamping finger cylinder are preferably adopted.
Referring to fig. 3 and 4, since the spool is generally cylindrical, in order to ensure that the spool can be clamped more stably, the spool clamping jaw 630 generally adopts more than three-finger clamping jaw cylinders, and the clamping jaw 620 and the second head clamping jaw 633 can meet the requirement by adopting two-finger clamping jaw cylinders because the clamping surfaces are flat. In this embodiment, spool clamp 630 employs a three finger clamp cylinder 631. The reel clamping jaw 630, the positioning camera 650, the gland clamping jaw 640 and the clamp clamping jaw 620 are all connected with the multi-axis mechanical arm 500 through the hand clamping module base 610, and the hand clamping module base 610 can rotate under the drive of the rotating shaft at the tail end of the multi-axis mechanical arm 500. The distance of the ends of the three spool gripping fingers 632 of the spool gripping jaw 630 from the center of the three finger gripping jaw cylinder 631 is determined according to the diameter of the spool to be gripped. The length of the collet fingers 632 needs to be greater than the length of the spool shaft on the device to avoid interference with the spool shaft during loading and unloading. Accordingly, the second tape head clamping jaw 633 needs to be disposed on the gripper module base 610 through the extension plate 634, so that the distance from the end of the clamping finger of the second tape head clamping jaw 633 to the gripper module base 610 is equal to the distance from the end of the reel clamping finger 632 to the gripper module base 610, and when the reel clamping jaw 630 can clamp the reel on the clamp base 210, the second tape head clamping jaw 633 can clamp the tape head for unwinding the coiled material.
In some devices, in order to firmly limit the spool on the spool spindle by the spool gland 720, a locking mechanism 721 is generally disposed between the spool gland 720 and the spool spindle, and when the spool gland 720 is disassembled, the locking mechanism 721 needs to be unlocked first. To solve the above technical problem, the gland clamping jaw 640 includes a gland clamping jaw for clamping the main body of the spool gland 720, and a buckle triggering mechanism for triggering the buckle mechanism 721 on the spool pressing plate, so that the spool gland 720 and the spool rotating shaft can be separated. Referring to fig. 3 and 4, in general, the spool gland 720 has a spindle sleeve 722 that mates with the spool spindle, and the gland clamping jaws facilitate clamping of the spool gland 720 by clamping the spindle sleeve 722. Referring to fig. 7, in the present embodiment, a rotary shaft sleeve 722 and a circular cover plate 724 are connected by a cylindrical sleeve base 723, the sleeve base 723 is clamped as a clamping part by a gland clamping jaw to clamp the spool cover plate 724, the gland clamping jaw includes a gland clamping cylinder 641 and an L-shaped gland clamping plate 642, the gland clamping cylinder 641 is a two-finger clamping cylinder, one end of the two L-shaped gland clamping plates 642 is connected with the gland clamping cylinder 641, and the other end is provided with a groove matched with the circumferential shape of the sleeve base 723 to ensure that the gland clamping plate 642 can firmly clamp the sleeve base 723. The structure of the buckle triggering mechanism needs to be designed according to the unlocking action of the actually adopted buckle mechanism, if the buckle triggering mechanism is in rotary unlocking, the buckle triggering mechanism can be a rotary cylinder or a motor and the like, and if the buckle triggering mechanism is in pressing unlocking, the buckle triggering mechanism can be a cylinder or an electric push rod and the like. Referring to fig. 7, in the present embodiment, the fastening mechanism 721 is a hook rotatably disposed on the drum gland 720, the bottom of the hook is rotatably connected with the sleeve base 723, a torsion spring is disposed between the hook and the sleeve base 723, and a fastening slot (not shown) matching with the hook portion at the upper end of the hook is disposed on the peripheral surface of the drum rotating shaft. The lower extreme of pothook is provided with presses the portion, and correspondingly, buckle trigger mechanism includes buckle trigger cylinder 643 and buckle push pedal 644, buckle push pedal 644 is connected with the piston rod of buckle trigger cylinder 643, buckle trigger cylinder 643 sets up between two gland splint 642, when gland clamping jaw clamping sleeve base 723, can make the buckle push pedal 644 and the portion of pressing of pothook opposite, buckle trigger cylinder 643 outwards release buckle push pedal 644 this moment, make buckle push pedal 644 press down the portion of pressing, make the pothook outwards overturn, the hook portion of the upper end of pothook can be separated with the draw-in groove in the reel pivot for reel gland 720 can be separated with the reel pivot.
It will be appreciated that the arrangement of the spool clamp jaw 630, clamp jaw 620, gland clamp jaw 640 and positioning camera 650 on the gripper module base 610 should be designed with the goal of not interfering with the respective functional actions of each other, and that the orientation between adjacent mechanisms should be perpendicular to each other in order to provide sufficient action space for each mechanism on the robot gripper module 600. In this embodiment, before taking and placing the reel and the reel gland 720, the reel clamping jaw 630, the clamp clamping jaw 620 and the gland clamping jaw 640 need to take a picture of the reel changing turntable 700 through the positioning camera 650, and are arranged on three adjacent sides of the positioning camera 650 with the positioning camera 650 as a center, so that when the mechanical clamping arm module 600 switches functions each time, only 90 degrees of rotation are needed, the efficiency of switching functions of the mechanical clamping arm module 600 is improved, and the beats of feeding and discharging actions are improved.
Referring to fig. 1 and 2, in the present embodiment, in order to facilitate management of rolls and empty reels, the material rack 300 includes an upper material rack 320 for storing the reel jigs 200 with rolls and a lower material rack 310 for storing the reel jigs 200 with empty reels, and a plurality of drawer positions 311 matching the width of the reel jigs 200 are provided inside each of the upper material rack 320 and the lower material rack 310 in a vertical direction, and storage of the reel jigs 200 is achieved by inserting the reel jigs 200 into the drawer positions 311.
