[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 and 2 As shown, an automatic roll-up device for a carpet-making machine includes an intermediate support 4 and a PLC controller. The rectangular intermediate support 4 is fixed to the ground by anchor bolts. Roll-up changing devices are hinged to both sides of the intermediate support 4. Each roll-up changing device includes a support frame 10, on which two rollers 12 are mounted parallel and spaced apart. The roll material is placed between the two rollers 12. A support plate 13 is provided between the two rollers 12. Both ends of the support plate 13 are fixedly connected to the support frame 10 via connecting plates 6. A through hole is provided on the support plate 13, and along the axis of the through hole... A through-beam photoelectric switch 15 is provided, which is used to detect whether there is a roll of material 14 on the roll changing device; an inclined plate 16 is provided above the intermediate support 4, and the inclined plate 16 is fixedly connected to the intermediate support 4 through the bracket 3; a first hydraulic cylinder 1 is also included, one end of the first hydraulic cylinder 1 is hinged to the connecting plate 6 in one of the roll changing devices, and the other end of the first hydraulic cylinder 1 is hinged to the first hinge seat 2 fixedly set on the ground; the photoelectric switch 15 is connected to the input terminal of the PLC controller, and the solenoid valve used to control the extension and retraction of the first hydraulic cylinder 1 is connected to the output terminal of the PLC controller.
[0021] To facilitate a better understanding of this patent by those skilled in the art, Figure 1The left-hand roll-changing device is designated as roll-changing device A, and the right-hand roll-changing device is designated as roll-changing device B. Normally, the roll 14 on roll-changing device A is fed into the carpet-making machine, while roll-changing device B holds a spare roll 14. When the through-beam photoelectric switch 15 detects that the roll 14 on roll-changing device A has been used up, it sends a signal to the PLC controller. Upon receiving this signal, the PLC controller drives the first hydraulic cylinder 1 by controlling the solenoid valve. The extension and retraction of the first hydraulic cylinder 1 causes the roll-changing device B, which is hinged to it, to rotate around the central support 4. During the rotation of roll-changing device B, the roll 14 on it rolls onto roll-changing device A due to gravity and the movement of the device, thus completing the roll-changing process. This ensures continuous production of the carpet-making machine and avoids shutdowns caused by untimely manual roll-changing.
[0022] It also includes a second hydraulic cylinder 11, one end of which is hinged to a connecting plate 6 in another winding device, and the other end of which is hinged to a fixedly installed second hinge seat 7. A solenoid valve for controlling the extension and retraction of the second hydraulic cylinder 11 is connected to the output terminal of a PLC controller. For example... Figure 3 As shown, before the roll 14 is rolled from the roll-changing device B to the roll-changing device A, the second hydraulic cylinder 11 drives the roll-changing device A to tilt at a certain angle. In this way, when the roll 14 rolls onto the roll-changing device A, it will not roll off onto the ground, thus ensuring the safety of the device.
[0023] The roll changing device also includes a first limit switch 8 and a second limit switch 5. The two first limit switches 8 are respectively mounted on the first hinge seat and the second hinge seat, and the two second limit switches 5 are respectively mounted on both sides of the bracket 3. A trigger plate 9 for triggering the first limit switches 8 is fixedly connected to one side of the support frame 10. The second limit switches 5 are triggered by the roller 12. The first limit switches 8 and the second limit switches 5 are connected to the input terminal of the PLC controller. These switches are connected to the input terminal of the PLC controller to detect the tilt angle of the roll changing device and provide feedback signals so that the PLC controller can control the start and stop of the roll changing device.
[0024] like Figure 4 and 5 As shown, the two first limit switches 8 are SQ1 and SQ2, the two second limit switches 5 are SQ3 and SQ4, the solenoid valves controlling the extension and retraction of the first cylinder 1 and the second cylinder 11 are three-position three-way solenoid valves, the two ends of the two three-position three-way solenoid valves are YA1, YA2, YA3 and YA4, respectively, and SQ1, SQ2, YA1, YA2, YA3 and YA4 are connected to the output terminal of the PLC controller.
[0025] A ramp 19 is provided on one side of one of the roll changing devices. The ramp 19 facilitates the operator to load the roll 14 12 onto the roll changing device.
[0026] A safety light curtain 18 is installed between the ramp plate 19 and the roll changing device, and the safety light curtain 18 is connected to the input terminal of the PLC controller. When the safety light curtain 18 detects a person or object in the area between the roll changing device and the ramp plate 19, the PLC controller keeps the roll changing device inactive to ensure safety during use.
[0027] It also includes an audible and visual alarm 17, which is connected to the output of the PLC controller. When the photoelectric switch 15 detects that no roll material 14 has been loaded onto the roll changing device B within 10 minutes, the audible and visual alarm 17 is activated and then stops after two minutes, reminding the staff to load the roll material 14 onto the roll changing device B to ensure the continuity of the carpet making machine.
[0028] A silencer button 20 is connected to the input terminal of the PLC controller. If the sound and light alarm 17 is activated and the staff arrives at the site within two minutes, the staff can manually turn off the sound and light alarm 17 using the silencer button 20 to avoid noise disturbance from the sound and light alarm 17 when the roll material 14 is being loaded.
[0029] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
