Description

Technical Field

[0001] This utility model relates to the field of wireless control technology, and more specifically, to a wireless control system for a fabric cart. Background Technology

[0002] In the textile, logistics, and intelligent manufacturing fields, fabric trolleys (or material handling trolleys) are known to be automated devices used to transport fabric rolls, semi-finished products, or finished products. They are widely used in garment factories, warehousing centers, and flexible production lines. However, traditional wired control or manual operation of fabric trolleys suffers from low flexibility, complex wiring, and high maintenance costs. Therefore, a wireless control system has been introduced to wirelessly control the fabric trolleys to perform corresponding operations, thus meeting the needs of compact spaces and dense equipment in textile workshops, avoiding the risk of cable entanglement, and improving mobility.

[0003] However, in actual use, the existing wireless control system uses conductive rails for power supply, that is, it provides power to the moving fabric trolley through fixedly installed conductive rails. It still requires operators to control it on-site. The operator needs to move with the fabric trolley to the corresponding feeding port position to stop the trolley and control the forward and backward movement of the fabric trolley and the electric push rod valve. Because it requires on-site operation, it is a hybrid solution of wired power supply and wireless control. It lacks the layout of control lines and cannot achieve interoperability between the control system and the network.

[0004] Therefore, this utility model proposes a wireless control system for fabric carts as a further improvement, so as to realize the interconnection of the control system and further facilitate remote control by staff. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] As attached Figure 1 The wireless control system for a fabric trolley shown includes: a transfer module 1, a position signal module 2, a signal processing module 3, and a remote control module 4.

[0038] Specifically, for the scenario of conveying materials via belt pulleys, the transfer module 1 is located on the fabric trolley; the position signal module 2 is located at the material inlet of the belt pulley; the signal processing module 3 is located in the electrical cabinet 5 set up on site; and the remote control module 4 is located in the remote power room so that the operator can remotely control the fabric trolley to transfer the fabric.

[0039] Signal processing module 3 includes: relay module 31, wireless transmission module 32, and wireless receiving module 33;

[0040] The electrical cabinet 5 is also equipped with a power switch 51 and a switching power supply 52. ​​The power switch 51 is used to provide 220V AC power to the electrical cabinet 5. The switching power supply 52 is used to provide power to the wireless transmitter module 32 and the wireless receiver module 33.

[0041] The transfer module 1 includes: a moving module 11 for driving the trolley to move and a module 12 for controlling the opening and closing of the valve;

[0042] The remote control module 4 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via cables.

[0043] The mobile module 11 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via the relay module 31; wherein, the mobile module 11 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via the relay module 31 and wireless signals.

[0044] The opening and closing module 12 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via the relay module 31; wherein, the opening and closing module 12 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via the relay module 31 and wireless signals.

[0045] The location signal module 2 is connected to both the wireless transmitting module 32 and the wireless receiving module 33 via cables.

[0046] In this system, if the trolley needs to be moved, the operator controls the remote control module 4. The remote control module 4 sends a corresponding electrical signal to the wireless transmission module 32 via a cable. Upon receiving the electrical signal, the wireless transmission module 32 sends the corresponding instruction to the mobile module 11 via the relay module 31 and then via wireless signal. The mobile module 11 executes the operation of moving the trolley according to the instruction. Subsequently, the mobile module 11 feeds back its status information to the wireless receiving module 33 via wireless signal and relay module 31. The wireless receiving module 33 then transmits the information to the remote control module 4 via cable. Finally, the remote control module 4 displays the corresponding information on the display screen so that the operator can perform the next operation. Therefore, the operator can remotely control the fabric trolley.

[0047] Similarly, if valve control is required, the operator controls the remote control module 4. The remote control module 4 sends a corresponding electrical signal to the wireless transmitter module 32 via a cable. Upon receiving the electrical signal, the wireless transmitter module 32 sends the corresponding instruction to the opening / closing module 12 via the relay module 31 and wireless signal. The opening / closing module 12 executes the valve opening / closing operation according to the instruction. Subsequently, the opening / closing module 12 feeds back its status information to the wireless receiver module 33 via the wireless signal and relay module 31. The wireless receiver module 33 then transmits this information to the remote control module 4 via a cable. Finally, the remote control module 4 displays the corresponding information on the display screen so that the operator can perform the next operation. Therefore, the operator can remotely control the opening / closing module 12 used to control the valve without the need for on-site personnel.

[0048] Among them, the position signal module 2 transmits the position signal of the fabric trolley to the wireless transmission module 32 through a cable: that is, the signal of the presence of the fabric trolley at the material inlet and the signal of the absence of the fabric trolley.

[0049] If the wireless transmitter module 32 receives a signal from the material inlet indicating that there is a fabric trolley, the wireless transmitter module 32 sends a stop command to the mobile module 11 via the relay module 31. The mobile module 11 then receives the command and stops the fabric trolley. Subsequently, the mobile module 11 sends its status information back to the wireless receiver module 33 via the wireless signal and the relay module 31. The wireless receiver module 33 then transmits the information to the remote control module 4 via a cable. Finally, the remote control module 4 displays the relevant information on the screen so that the operator can perform the next step.

[0050] If the wireless transmitting module 32 receives a signal that there is no material feeding trolley at the material inlet, the wireless transmitting module 32 sends a feedback instruction to the mobile module 11 via the relay module 31. The mobile module 11 then sends its status information to the wireless receiving module 33 in real time via the wireless signal and the relay module 31. The wireless receiving module 33 then transmits the information to the remote control module 4 via a cable. Finally, the remote control module 4 displays the relevant information on the display screen so that the operator can perform the next step of the operation. Therefore, the operator can accurately locate the stopping position of the material feeding trolley.

[0054] The opening and closing module 12 is connected to the wireless transmitting module 32 and the wireless receiving module 33 via the second relay 312.

[0066] The proximity sensor 21 is composed of multiple sensors. When the fabric trolley approaches the material inlet, the proximity sensor 21 is activated. Then, the proximity sensor 21 transmits a stop signal to the wireless transmission module 32 through a cable. The wireless transmission module 32 transmits the stop signal to the movement module 11 through the first relay 311. After the movement module 11 stops, it feeds back the position signal of the fabric trolley to the wireless receiving module 33 through the first relay 311, thus accurately locating the stopping position of the fabric trolley.
