The inner ring of the rear bearing 53 of the robotic arm swing feeding drive shaft at the front end is abutted by the rear step of the robotic arm swing feeding drive shaft 43, and the outer ring of the rear bearing 53 of the robotic arm swing feeding drive shaft at the rear end is positioned by a retaining ring (not marked in the figure).
[0071] The robotic arm device used in this embodiment of the fully automatic knitting machine is used in conjunction with the fully automatic knitting machine.
[0072] In use, the end of the woven material moves downward along the left wall of the feed trough 5 on the frame plate 37 (the right cavity of the feed trough 5 is controlled by other devices of the fully automatic braiding machine to prevent a large amount of woven material from falling in at the same time and causing congestion) to the material trough 54 opened in the middle of the upper side of the material receiving plate 2 between the upper right side of the left end "I" part of the moving clamping arm 3 and the upper part of the left end face of the stationary clamping arm 4, which is the gripper jaw. At this time, under the action of external force, the robotic gripping and releasing power shaft crank arm 18 rotates counterclockwise with the robotic gripping and releasing power shaft 39, and then swings counterclockwise together with the gripping and releasing swing inner rod 26 and the gripping and releasing swing surface rod 11 (see Figure 1 and Figure 5 Next, the clamping and releasing swing cam 33, which is held between the moving and stationary clamping arm sliding block bearing 10 and the stationary clamping arm sliding block bearing 31, swings downward and disengages from the clamping of the moving and stationary clamping arm sliding block bearings 10 and 31. At this time, under the action of the reset spring 34 of the clamping and releasing swing mechanism, the moving clamping arm sliding block 8 moves the moving clamping arm 3 to the right, while the stationary clamping arm sliding block 29 moves the stationary clamping arm 4 to the left, until the robotic arm clamp formed by the upper right side of the left end "I" of the moving clamping arm 3 and the upper part of the left end face of the stationary clamping arm 4 clamps the knitted material. Then, under the action of external force, the robotic arm swing feeding push shaft crank arm 44 rotates the robotic arm swing feeding push shaft 43 and the robotic arm swing feeding push rod 9 in a counterclockwise direction (see Figure 1 and Figure 5 As the upper end of the robotic arm's swing feeding push rod 9 abuts against the upper left step of the arc-shaped groove 51 in front of the slide bottom plate 7, the counterclockwise rotation of the robotic arm's swing feeding push rod 9 causes the slide bottom plate 7, along with the moving clamp arm 3 and the stationary clamp arm 4 and the woven material they clamp, to swing downwards and to the left to the discharge hole 1 of the frame plate 37. Then, under the action of external force, the robotic arm's clamping and releasing power shaft crank arm 18 rotates clockwise, causing the robotic arm's clamping and releasing power shaft 39 to rotate. This, in turn, causes the clamping and releasing swing inner rod 26, along with the clamping and releasing swing surface rod 11, to swing clockwise (see...). Figure 1 and Figure 5The clamping and releasing swing cam 33 swings upward, squeezing apart the moving and stationary clamping arm sliding block bearings 10 and 31, allowing them to clamp the clamping and releasing swing cam 33. Simultaneously, the moving clamping arm sliding block 8 moves the moving clamping arm 3 to the left, and the stationary clamping arm sliding block 29 moves the stationary clamping arm 4 to the right, thus releasing the gripper's grip on the knitting material. Next, the automatic knitting machine's pushing device pushes the loosened knitting material to the left from the receiving trough 54 to the discharge hole 1, where it is fed into the automatic knitting machine by the feeding rollers. Then, under external force, the manipulator's swing feeding push shaft crank arm 44 rotates clockwise along with the manipulator's swing feeding push shaft 43 and the manipulator's swing feeding push rod 9 (see...). Figure 1 and Figure 5 At this point, the upper end of the robotic arm swing feeding push rod 9 gives up its contact with the upper left step of the arc-shaped groove 51 in front of the slide bottom plate 7. Therefore, under the action of the robotic arm swing feeding reset spring 22, the slide bottom plate 7 also rotates clockwise, bringing the moving clamp arm 3 and the stationary clamp arm 4 back to their original positions. Thus, the clamping and swing feeding process of a piece of woven material is completed.
[0073] Example 2:
[0074] The robotic arm device used in the fully automatic knitting machine in this embodiment is an improvement on Embodiment 1. The difference between it and Embodiment 1 is that:
[0075] First, the robotic gripper release power assembly consists of a robotic gripper release power shaft 39, a robotic gripper release power bearing seat 38, a robotic gripper release power shaft crank arm 18, a robotic gripper release power shaft crank arm joint 19 (a fisheye joint, i.e., a self-lubricating rod end joint bearing), a robotic gripper release power cam connecting rod 24, and a robotic gripper release power cam mechanism (not shown in the figure).
[0076] The front end of the robotic arm gripping and releasing power shaft 39 is connected to the middle of the gripping and releasing swing inner rod 26. Its rear end extends out of the right side of the frame plate 37 and then through the robotic arm gripping and releasing power bearing seat 38 located behind the frame plate 37. One end of the robotic arm gripping and releasing power shaft crank arm 18 is then fitted onto it. The other end of the robotic arm gripping and releasing power shaft crank arm 18 is hinged to the robotic arm gripping and releasing power shaft crank arm joint 19 through the robotic arm gripping and releasing power shaft crank arm pin 17. The upper end of the robotic arm gripping and releasing power cam connecting rod 24 is connected to the lower end of the robotic arm gripping and releasing power shaft crank arm joint 19, and the lower end of the robotic arm gripping and releasing power cam connecting rod 24 is connected to the robotic arm gripping and releasing power cam mechanism.
[0077] Secondly, the power assembly for the swing feeding of the robotic arm consists of a swing feeding drive shaft 43, a rear bearing seat 41 for the swing feeding drive shaft, a crank arm 44 for the swing feeding drive shaft, a crank arm joint 46 for the swing feeding drive shaft (which is a fisheye joint, i.e., a self-lubricating rod end joint bearing), a power cam connecting rod 25 for the swing feeding drive, and a cam mechanism for the swing feeding drive (not shown in the figure).
[0078] The robotic arm swing feeding drive shaft 43, which passes through the rear end of the robotic arm swing feeding drive bearing seat 48, passes through the rear bearing seat 41 of the robotic arm swing feeding drive shaft located in the middle right part behind the frame plate 37, and then one end of the robotic arm swing feeding drive shaft crank arm 44 is fitted. The other end of the robotic arm swing feeding drive shaft crank arm 44 is hinged to the robotic arm swing feeding drive shaft crank arm joint 46 through the robotic arm swing feeding drive shaft crank arm pin 45. The upper end of the robotic arm swing feeding drive power cam connecting rod 25 is connected to the lower end of the robotic arm swing feeding drive shaft crank arm joint 46, and the lower end of the robotic arm swing feeding drive power cam connecting rod 25 is connected to the robotic arm swing feeding drive cam mechanism.
[0079] During its use, when the robotic arm gripping and releasing power cam mechanism moves the robotic arm gripping and releasing power cam connecting rod 24 upward, it drives the robotic arm gripping and releasing power shaft crank arm 18 and the robotic arm gripping and releasing power shaft 39 to rotate counterclockwise. This, in turn, causes the gripping and releasing swing inner rod 26 and the gripping and releasing swing surface rod 11 to swing counterclockwise together (see...). Figure 1 and Figure 5 Next, the clamping and releasing swing cam 33, which is held between the moving and stationary clamping arm sliding block bearing 10 and the stationary clamping arm sliding block bearing 31, swings downward and disengages from the clamping of the moving and stationary clamping arm sliding block bearings 10 and 31. At this time, under the action of the reset spring 34 of the clamping and releasing swing mechanism, the moving clamping arm sliding block 8 moves the moving clamping arm 3 to the right, while the stationary clamping arm sliding block 29 moves the stationary clamping arm 4 to the left, until the robotic arm clamp formed by the upper right side of the left end "I" part of the moving clamping arm 3 and the upper part of the left end face of the stationary clamping arm 4 clamps the knitted material. Then, the robotic arm swing feeding push cam mechanism moves the robotic arm swing feeding push power cam connecting rod 25 downward, causing the robotic arm swing feeding push shaft crank arm 44, along with the robotic arm swing feeding push shaft 43 and the robotic arm swing feeding push rod 9, to rotate counterclockwise (see Figure 1 and Figure 5As the upper end of the robotic arm's swing feeding push rod 9 abuts against the upper left step of the arc-shaped groove 51 in front of the slide bottom plate 7, the counterclockwise rotation of the robotic arm's swing feeding push rod 9 causes the slide bottom plate 7, along with the moving clamp arm 3 and the stationary clamp arm 4 and the woven material it clamps, to swing downwards and to the left to the discharge hole 1 of the frame plate 37. At this point, the robotic arm's gripping and releasing power cam mechanism moves the robotic arm's gripping and releasing power cam connecting rod 24 downwards, causing the robotic arm's gripping and releasing power shaft crank arm 18, along with the robotic arm's gripping and releasing power shaft 39, to rotate clockwise. This, in turn, causes the gripping and releasing swing inner rod 26, along with the gripping and releasing swing surface rod 11, to swing clockwise (see...). Figure 1 and Figure 5 The manipulator swings upward with the clamping release swing cam 33, squeezing apart the moving and stationary clamping arm sliding block bearings 10 and 31, allowing them to clamp the clamping release swing cam 33. Simultaneously, the moving clamping arm sliding block 8 moves to the left with the moving clamping arm 3, and the stationary clamping arm sliding block 29 moves to the right with the stationary clamping arm 4, thus releasing the gripper from the fabric. Next, the automatic knitting machine's pusher pushes the loosened fabric to the left from the receiving trough 54 to the discharge hole 1, where it is fed into the automatic knitting machine by the feed rollers. Then, the manipulator swing feeding push cam mechanism moves upward with the manipulator swing feeding push power cam connecting rod 25, causing the manipulator swing feeding push shaft crank arm 44 and the manipulator swing feeding push shaft 43, along with the manipulator swing feeding push rod 9, to rotate clockwise (see...). Figure 1 and Figure 5 At this point, the upper end of the robotic arm swing feeding push rod 9 gives up its contact with the upper left step of the arc-shaped groove 51 in front of the slide bottom plate 7. Therefore, under the action of the robotic arm swing feeding reset spring 22, the slide bottom plate 7 also rotates clockwise, bringing the moving clamp arm 3 and the stationary clamp arm 4 back to their original positions. Thus, the clamping and swing feeding process of a piece of woven material is completed.
[0080] Everything else is basically the same as in Example 1, and will not be repeated here.
[0081] The robotic arm device for the fully automatic weaving machine of the present invention is used in conjunction with the fully automatic weaving machine and can weave various types of mats, curtains, and decorative fabrics.
