In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0028] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a film transport trolley moving and positioning device, including a slitting machine 1, a track 2, a film transport trolley 3, a driving assembly 4 and a controller (not shown); the slitting machine 1 includes a frame (not shown), a winding servo (not shown) and a winding arm 11, the winding servo is connected to the frame, the winding arm is connected to the output end of the winding servo, and the winding arm 11 is used to fix the film roll 100; the track 2 is arranged below the winding arm 11; the film transport trolley 3 is slidably connected to the track 2; the driving assembly 4 is connected to the film transport trolley 3, and the driving assembly 4 can drive the film transport trolley 3 to move along the track 2; the controller is electrically connected to the winding servo and the driving assembly 4, and the controller is used to control the driving assembly 4 to drive the film transport trolley 3 to move from the starting position of the track 2 to the preset position of the track 2. When the film transport trolley 3 is in the preset position, the central axis of the film transport trolley 3 coincides with the radial direction of the film roll 100.

[0029] As one of the optional implementations of this embodiment, the preset position is calculated by the following formula:

[0030] Where x is the distance from the starting position to the preset position; d is the horizontal distance from the starting position to the rotation center of the winding arm 11; a is the distance from the rotation center of the winding arm 11 to the fixed center of the film roll 100; b is the radius of the film roll 100; and c is the vertical height from the outer end point of the film roll 100 to the rotation center of the winding arm 11. Specifically, the above formula can be programmed into a PLC program and embedded into the controller to implement the controller's control functions. For implementation scenarios with different size standards, simply modify the corresponding parameters.

[0031] like Figure 1 As shown, g is the height from the horizontal plane to the rotation center of the winding arm 11, and f is the distance from the rotation center of the winding arm 11 to the central axis of the film transport trolley 3. a, b, c, d, and g all have fixed values ​​and can be obtained through measurement. The specific solution process for x is as follows:

[0032] n=b+c, ​​e, a, n are the three right-angled sides of a right triangle. According to the Pythagorean theorem, we know that: e 2 =a 2 -n 2 ;

[0033] f=e, .

[0034] As one of the optional implementations of this embodiment, a pressure sensing component 5 is provided at a preset position.

The pressure sensor 52 is disposed on the top surface of the ramp 51, which is disposed on the track 2. When the film transport trolley 3 moves to a preset position, it moves along the ramp 51 to the pressure sensor 52 on the ramp 51. The pressure sensor 52 is squeezed and senses a pressure change, thereby determining that the film transport trolley 3 has moved to the preset position. The pressure sensor 52 is electrically connected to the controller, which feeds back the pressure change information to the controller, which then controls the winding arm 11 to lower the film roll 100.

[0036] As one of the optional implementations of this embodiment, the track 2 is provided with a receiving groove 21 at a preset position, and the pressure sensing component 5 further includes a spring 53, one end of which is connected to the bottom of the ramp 51, and the other end of which is connected to the bottom of the receiving groove 21. When the film transport trolley 3 moves to the preset position, the film transport trolley 3 presses against the ramp 51, and the spring 53 is compressed and hidden in the receiving groove 21, so that the surface of the ramp 51 is flush with the surface of the track 2, thereby preventing the ramp 51 from affecting the placement height of the film transport trolley 3 on the track 2.

[0037] As one of the optional implementations of this embodiment, the film transport trolley 3 includes a vehicle body 31 , a tray 32 and a plurality of wheels 33 . The plurality of wheels 33 are arranged at the bottom of the vehicle body 31 , and the tray 32 is arranged at the top of the vehicle body 31 .

[0038] As an optional implementation of this embodiment, the tray 32 is provided with an inverted triangular groove 321. Both sides of the inverted triangular groove 321 can fit the outer circumference of the film roll 100 to limit the film roll 100 so as to achieve stable placement of the film roll 100.

[0039] As one of the optional implementations of this embodiment, track 2 is a linear track, and drive assembly 4 includes a motor 41, a nut (not shown), and a screw 42. The end of screw 42 is connected to the output end of motor 41. Screw 42 is threadedly connected to the nut, which is connected to film transport carriage 3. Motor 41 drives screw 42 to rotate, thereby driving film transport carriage 3. By controlling the number of rotations of screw 42, the displacement of film transport carriage 3 can be precisely controlled.

[0040] The steps for using the film transport trolley mobile positioning device provided in this embodiment are as follows:

[0041] 1. The operator starts the drive assembly 4, which drives the film transport trolley 3 to move. The film transport trolley 3 moves from the starting position along the track 2 to the preset position.

[0042] 2. The operator presses the lower film roll laying button on the slitting machine 1 , and the winding arm 11 drops the film roll 100 onto the tray 32 of the film transport trolley 3 .

[0043] 3. The operator presses the film roll clamping button of the winding arm 11 to open the film roll 100, and the film roll 100 falls onto the tray 32 of the film transport trolley 3.

[0044] 4. The operator presses the reel arm upright button on the slitting machine 1, and the reel arm 11 rotates upright.

[0045] 5. The operator starts the drive assembly 4, and the film transport trolley 3 carrying the film roll 100 moves along the track 2 to the starting position.

[0046] 6. The operator operates the film transport trolley 3 to transport the film roll 100 to the packaging area.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
