Description

Technical Field

[0001] The present invention relates to the technical field of intelligent textile machinery, and particularly to a mobile cloth roller cutting device based on an intelligent unloading trolley. Background Art

[0002] During the cloth weaving process of a textile machine, due to the long duration of weaving, the finished cloth is wound around a cloth shaft into a roller shape and then taken down. Currently, manual replacement of the roll is generally adopted. However, since the cloth shaft full of cloth is heavy, manual shaft replacement is time-consuming and laborious, with low efficiency. With the continuous progress of technology, more and more machines have replaced manual repetitive and labor-consuming work.

Detailed implementation mode

[0024] An embodiment of the present invention provides a mobile cloth roller cutting device based on an intelligent unloading trolley, as Figures 1-7 shown, including a carrier 3 and two groups of unloading mechanisms 5. A plurality of groups of drive wheels 2 are arranged at the bottom of the carrier 3, and a drive motor is arranged on the drive wheels 2. The drive motor is used to drive the drive wheels 2 to rotate.

[0025] As Figure 1 shown, the two groups of unloading mechanisms 5 are arranged on the carrier 3. The unloading mechanism 5 is used to unload the cloth shaft 12. The unloading mechanism 5 includes a first rotating arm 51, a supporting arm 52, a supporting arm rack 53, and a supporting arm gear 54. The first rotating arm 51 is rotatably connected to the carrier 3, and a motor connected to the rotating shaft of the first rotating arm 51 is arranged on the carrier 3. This motor is used to drive the first rotating arm 51 to rotate. The top of the first rotating arm 51 is arc-shaped, and the supporting arm 52 is consistent with the arc of the top of the first rotating arm 51. The supporting arm 52 is respectively slidably adapted along the arc direction of the top of the first rotating arm 51. The supporting arm rack 53 is arranged at the bottom along the arc direction of the supporting arm 52. The supporting arm gear 54 is pivotally connected to the first rotating arm 51 and meshes with the supporting arm rack 53. A gear motor connected to the supporting arm gear 54 is arranged on the rotating arm 13. The gear motor is used to drive the supporting arm gear 54 to rotate, so as to drive the supporting arm 52 to rotate along the arc direction of the top of the first rotating arm 51.

[0026] As Figure 1As shown in the figure, a cloth cutting mechanism 6 is provided at the front end of the discharging mechanism 5 on the carrier 3. The cloth cutting mechanism 6 includes a second rotating arm 61, a support arm 62, a first clamping arm 63, a second clamping arm 64, a first gear 65, a second gear 66, and a laser cutting gun 68. The second rotating arm 61 is rotatably connected to the front end of the carrier 3. A motor connected to the rotating shaft of the second rotating arm 61 is provided on the carrier 3, and this motor is used to drive the second rotating arm 61 to rotate. The support arm 62, the first clamping arm 63, and the second clamping arm 64 are all semi-circular. The support arm 62 is provided at the top of the second rotating arm 61. The first clamping arm 63 and the second clamping arm 64 are respectively slidably fitted on both sides of the top of the support arm 62 along the arc direction of the top of the support arm 62. Arc-shaped racks are provided at the bottoms of the first clamping arm 63 and the second clamping arm 64 along their arc directions. Two sides of the support arm 62 are pivotally connected with the first gear 65 and the second gear 66. The first gear 65 and the second gear 66 are respectively engaged with the arc-shaped racks at the bottoms of the first clamping arm 63 and the second clamping arm 64. The first gear 65 and the second gear 66 are respectively used to drive the first clamping arm 63 and the second clamping arm 64 to rotate along their arc directions, and the rotating directions of the first clamping arm 63 and the second clamping arm 64 are different. When the first clamping arm 63 and the second clamping arm 64 completely extend out of the support arm 62, a ring shape is formed among the support arm 62, the first clamping arm 63, and the second clamping arm 64. Two gear motors respectively connected with the first gear 65 and the second gear 66 are provided inside the support arm 62, and these two gear motors are respectively used to drive the first gear 65 and the second gear 66 to rotate. Corresponding top plates 67 are provided at the ends where the first clamping arm 63 and the second clamping arm 64 extend out of both ends of the support arm 62. Two laser cutting guns 68 are respectively provided on the two top plates 67. When the first clamping arm 63 and the second clamping arm 64 completely extend out of the support arm 62, the two laser cutting guns 68 are obliquely corresponding up and down. The laser lines emitted by the laser cutting guns 68 do not directly irradiate corresponding to each other, but are obliquely corresponding, and the two laser lines intersect, avoiding mutual damage of the laser cutting guns 68. The laser cutting gun 9 is an existing commercially available product for cloth cutting, and details are not elaborated here.

[0027] As Figure 6 shown, when the discharging trolley travels to the head of the textile machine where discharging is required, the support arm 62 is adjusted to cover the cloth shaft 12. After the first clamping arm 63 and the second clamping arm 64 rotate to clamp the cloth 13, the laser cutting gun 68 is started to cut the cloth. Then the trolley travels along the length direction of the cloth shaft 12. When the trolley reaches the discharging position, the laser cutting gun 68 completely cuts the cloth 13. Finally, the cloth shaft 12 is unloaded by using the discharging mechanism 5. This device cuts the cloth 12 while the trolley is traveling, greatly shortening the interval time between cloth cutting and discharging, and having high efficiency.

[0028] As Figures 2-3As shown in the figure, corresponding cutting torch power-off mechanisms 7 are provided on two top plates 67. The cutting torch power-off mechanism 7 includes a limit groove 71, a conductive wheel 72, a guide rail 73, a guide block 74 slidably fitted on the guide rail 73, and a spring 75. The limit groove 71 is provided on the top plate 67. The guide rail 73 is arranged on both sides inside the limit groove 71 along the depth direction of the limit groove 71. The conductive wheel 72 is pivotally connected to the guide block 74. The spring 75 is provided at the bottom of the guide block 74. When the two conductive wheels 72 are in contact, the circuit of the laser cutting torch 68 is disconnected through the trigger circuit. When the first clamping arm 62 and the second clamping arm 64 are fully extended, the spring 75 is used to make the two conductive wheels 72 abut against each other. During cutting, the two conductive wheels 72 are clamped on the upper and lower sides of the fabric 13.

[0029] As Figure 7 shown, the trigger circuit includes a controller, an electromagnet 14, an alarm 15, a normally closed dry reed switch 16, a normally open dry reed switch 17, a magnet switch 18, and a main switch 19. The electromagnet 14, the alarm 15, and the laser cutting torch 68 are connected in parallel. The magnet switch 18 is arranged on the branch circuit in front of the electromagnet 14. The front and rear connection terminals of the magnet switch 18 are the two conductive wheels 72. The normally closed dry reed switch 16 is arranged on the branch circuit in front of the laser cutting torch 68. The normally open dry reed switch 17 is arranged on the branch circuit in front of the alarm 15. The main switch 19 is arranged on the main circuit and is connected to the controller. The normally open dry reed switch 17 and the normally closed dry reed switch 16 are a kind of magnet-sensitive special switches and are existing mature components.

[0030] Principle of the trigger circuit: When the cloth cutting mechanism 6 is in place, the two laser cutting torches 68 correspond to the upper and lower sides of the fabric 13. The two conductive wheels 72 are clamped on the upper and lower sides of the fabric 13. Then the controller controls the main switch 19 to close, making the trigger circuit energized. At this time, the laser cutting torch 68 works energized. Then the controller controls the trolley to travel along the length direction of the fabric 13. When the laser cutting torch 68 reaches the tail and completely cuts off the fabric, at the same time, the two conductive wheels 72 also disengage from the fabric 13 and come into direct contact with each other; the two conductive wheels 72 connect the circuit of the electromagnet 14, and the electromagnet 14 is magnetized. At this time, the normally closed dry reed switch 16 is demagnetized and disconnected, and the laser cutting torch 68 stops working powered off. The normally open dry reed switch 17 is magnetized and closed, connecting the circuit of the alarm 15, making the alarm 15 alarm to remind that the fabric 13 has been completely cut. Then the controller controls the main switch 19 to turn off the circuit.

[0031] The trigger circuit can prevent the laser cutting torch 68 from continuing to work when the fabric 13 is completely cut, and prevent the laser cutting torch 68 from causing cutting damage to the fabric on the cloth shaft 12.

[0032] As Figure 2 shown, a leveling mechanism 8 is provided on the support arm 52. The leveling mechanism 8 can automatically level the cloth shaft 12 placed on the support arm 52 to the middle position of the support arm 52.

[0033] As shown Figure 5 in FIG. Figure 5 , the leveling mechanism 8 includes an intermediate wheel 81, two side wheels 82, three water chambers 83, and three pistons 84 movably connected to the water chambers 83 in a piston type. One of the water chambers 83 is disposed in the middle of the support arm 52, and the other two water chambers 83 are disposed in the support arm 52 and symmetrically arranged on both sides of the middle water chamber 83. An intermediate wheel 81 and two side wheels 82 are respectively pivotally connected to the tops of the three pistons 84, and the three water chambers 83 are connected by a connecting pipe 85. Under normal conditions, the water injection volume in the two side water chambers 83 is half of their capacity, and the water injection volume in the middle water chamber 83 is in a full state.

[0034] Since the initial state of the cloth shaft 12 entering the support arm 52 is not at the center position of the support arm 52. When the cloth shaft 12 enters the support arm 52, once the cloth shaft 12 contacts the side wheel 82 on the side, the friction between the cloth shaft 12 and the support arm 52 is greatly reduced, and under the action of its own gravity, while driving the side wheel 82 to rotate, the cloth shaft 12 moves towards the center of the support arm 52. When the cloth shaft 12 rolls to the center position of the support arm 52, the cloth shaft 12 presses the intermediate wheel 81, and the intermediate wheel 81 presses the piston 84 downward, so that the water in the middle water chamber 83 is squeezed into the two side water chambers 83. The pistons 84 in the two side water chambers 83 squeeze the side wheels 82 outwards, and the two side wheels 82 limit the upper sides of both sides of the cloth shaft 12, so that it is stably supported at the middle position of the support arm 52.

[0035] As shown Figure 1 in FIG. Figure 1 , the device further includes a chassis 1 and a reversing mechanism 4. A plurality of groups of driving wheels 2 are disposed at the bottom of the chassis 1. The reversing mechanism 4 includes an annular slide rail 41 and an annular slider 42 slidably fitted in the annular slide rail 41. The annular slide rail 41 is disposed on the chassis 1, and the carrier 3 is connected to the annular slider 42. A plurality of through fixing holes are vertically formed on the chassis 1 and the carrier 3, and the upper and lower fixing holes are connected by fixing bolts 43.

[0036] When the cloth cutting mechanism 6 needs to change the direction to cut the cloth of the textile machine on the other side, first unscrew the fixing bolt 43, then rotate the carrier 3 by 180°, and then screw the fixing bolt 43 back on.

[0037] As shown Figure 4 in FIG. Figure 4 , a mechanism cavity 10 is formed in the middle of the bottom of the carrier 3, a through hole 11 corresponding to the mechanism cavity 10 is formed on the chassis 1, and an anti-slip mechanism 9 is disposed in the mechanism cavity 10. The anti-slip mechanism 9 can support on the ground.

[0038] The anti-skid mechanism 9 includes an anti-skid plate 91, an electric push rod 92, a guide rod 93 and a guide sleeve 94. The electric push rod 92 is vertically arranged in the mechanism cavity 10, the anti-skid plate 91 is arranged on the output end at the bottom of the electric push rod 92, the guide rod 93 is vertically arranged in the mechanism cavity 10, the anti-skid plate 91 is concave, and the top two ends of the anti-skid plate 91 are connected to the guide sleeve 94.

[0039] When the cloth cutting mechanism 6 has finished cutting the cloth 13 and needs to put down the cloth shaft 12 , the electric push rod 92 pushes the anti-slide plate 91 to the ground to prevent the trolley from tipping over or deflecting during the process of putting down the cloth shaft 12 .

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
