Description

Technical Field

[0001] The present invention relates to the field of underwear machines, and in particular to a production monitoring system and method for underwear machines cluster. Background Art

[0002] like Figure 1 As shown, a lingerie machine typically has a discharge pipe 9 and a fabric outlet 10. A second suction pipe 11 is installed on the side wall of the outlet 10. The other end of the second suction pipe is connected to the machine's own exhaust fan. The second suction pipe is also equipped with a suction valve controller 12 to control the suction level. After the lingerie machine produces a piece of underwear, the exhaust fan draws air outward, creating a negative pressure in the discharge pipe. Under this negative pressure, the underwear passes through the discharge pipe and the fabric outlet and falls into a collection basket near the lingerie machine. Quality inspectors then inspect each piece of underwear in the collection basket, rejecting any defective pieces. The machine operator then performs repairs and adjustments on the lingerie machine that produced the defective pieces. In actual production, a workshop often has multiple underwear machines. A single quality inspector needs to inspect underwear preforms produced by multiple underwear machines. However, due to physical limitations, it is impossible for the inspector to constantly move between the machines and inspect each underwear preform immediately after it is produced. Instead, the inspector often has to wait until a machine has produced multiple underwear preforms before conducting a unified inspection. This reduces the inspector's workload, but when an underwear machine malfunctions, it is often not discovered in time, resulting in multiple underwear preforms becoming defective and increasing production costs. Therefore, it is necessary to propose a monitoring system that eliminates the need for inspectors to move between the machines and can promptly inspect the underwear preforms produced by each underwear machine. Summary of the Invention

[0003] The present invention solves the above problems and provides an underwear machine cluster production monitoring system that centrally transports underwear blanks, eliminates the need for quality inspectors to move between underwear machines, and can timely inspect the underwear blanks produced by each underwear machine and remotely control each underwear machine.

[0004] The technical solution adopted by the present invention to solve its technical problems is an underwear machine cluster production monitoring system, including: a product conveying channel, which includes a terminal discharge port and several feed ports. Each feed port is successively connected to the discharge pipes of each underwear machine through a temporary storage mechanism and a channel conversion mechanism. An air suction device is provided in the product conveying channel to form a negative pressure in the product conveying channel to convey the products of each underwear machine to the collection box at the terminal discharge port; a terminal controller, which is arranged near the terminal discharge port and is used to separately control each underwear machine to stop work and transmit product defect information to the corresponding sub-terminal device; the sub-terminal device is located near each underwear machine and corresponds to the underwear machine one by one. The sub-terminal device includes a display screen and control buttons. The display screen is used to display the product problem information received from the terminal controller, and the control buttons are used to control the corresponding temporary storage mechanism, channel conversion mechanism and display screen.

[0005] As a preferred solution of the above solution, the channel conversion mechanism includes a three-way joint, a first baffle, a first cylinder, a second baffle and a second cylinder. The first end of the three-way joint is connected to the discharge pipe of the underwear machine, the second end is connected to the temporary storage mechanism, and the third end is connected to the original cloth outlet of the underwear machine. The first baffle is arranged at the second end of the three-way joint, and the second baffle is arranged at the third end of the three-way joint. The first baffle is driven by the first cylinder, and the second baffle is driven by the second cylinder. The first cylinder and the second cylinder are jointly controlled by the terminal controller and the sub-terminal device. Different telescopic combinations of the first cylinder and the second cylinder can change the conduction state of the three ends of the three-way joint, so as to control whether the underwear embryo enters the temporary storage mechanism or enters the original cloth outlet of the underwear machine.

[0006] As a preferred solution of the above solution, the temporary storage mechanism includes a first transition part, a second transition part, a third baffle and a third cylinder. The first end of the first transition part is connected to the channel conversion mechanism, the second end of the first transition part is connected to the second end of the second transition part, the first end of the second transition part is connected to the feed port of the product conveying channel, and the third baffle is arranged at the connection between the first transition part and the second transition plate. The third baffle is driven by the third cylinder.

[0007] As a preferred solution of the above solution, a first through hole is provided on the side of the first transition part, and the first through hole is connected to the air suction valve controller of the underwear machine through a first air suction pipe. A first grid fence matching the inner wall of the first transition part is provided in the first transition part. The setting of the first grid fence can prevent the underwear embryo from being sucked into the first air suction pipe.

[0008] As a preferred embodiment of the above solution, the terminal controller includes a host that communicates with each sub-terminal device, a remote controller for controlling the shutdown of each underwear machine, and an underwear machine operation status panel. The underwear machine operation status panel is provided with indicator lights corresponding to the number of underwear machines, and the status of the indicator lights corresponds to the operation status of the underwear machines.

[0009] As a preferred embodiment of the above solution, the control end of the third cylinder is connected to the output end of the PLC controller, and the input ends of the PLC controller are respectively connected to each underwear machine. After an underwear blank is completed, the underwear machine will send a signal. After receiving the signal, the PLC controller controls the operation of the third cylinder. The PLC can also sort the concurrent signals to prevent multiple underwear blanks from entering the product conveying channel simultaneously.

[0010] The present invention also provides a method for monitoring the cluster production of underwear machines. Using the above system, it includes the following steps:

[0011] S1: After the underwear machine completes the underwear blank, the product conveying channel conveys the underwear blanks produced by each underwear machine to the terminal discharge port;

[0012] S2: Inspect each underwear blank coming out of the terminal discharge port. If a defect is found in the underwear blank, determine the underwear machine that produced the underwear blank according to the machine number on the underwear blank. Control the underwear machine to stop working through the terminal controller and send the defect information of the underwear blank to the corresponding sub-terminal device, and then enter step S3; when the underwear machine stops working, the corresponding indicator light on the underwear machine operation status panel lights up. At the same time, make the first baffle close the second end of the three-way joint, and the second baffle retracts to connect the underwear machine discharge pipe and the original cloth outlet;

[0013] S3: The weaver repairs the underwear machine according to the defect information displayed on the sub-terminal device. After the repair, start the underwear machine and check whether there are defects in the underwear blanks falling from the original cloth outlet of the underwear machine. If there are defects, repair it again. If not, make the second baffle close the third end of the three-way joint through the control button, and the first baffle retracts to conduct the discharge pipe and the temporary storage mechanism, so that the underwear blank can enter the temporary storage mechanism. At the same time, eliminate the defect information displayed on the sub-terminal device and turn off the corresponding indicator light of the underwear machine.

[0014] Quality inspectors can inspect the lingerie blanks produced by all lingerie machines without walking between each lingerie machine. When problems are found, they can remotely control the malfunctioning lingerie machine to stop production, adjust the state of the corresponding channel conversion mechanism to prevent the lingerie blanks produced by this lingerie machine from entering the product conveying channel again, and at the same time transmit the specific problems to the corresponding sub-terminal device for the loom fixer to perform maintenance. During maintenance, the lingerie blanks produced by the lingerie machine fall from its original cloth outlet, which is convenient for the loom fixer to judge whether the problem is solved. After the problem is solved, the defect information is eliminated again, and the channel conversion mechanism is adjusted so that the lingerie blanks produced by this lingerie machine can enter the product conveying channel again.

[0015] As a preferred solution of the above scheme, after the terminal controller controls the lingerie machine to stop, it cannot control this lingerie machine until the loom fixer eliminates the defect information of this lingerie machine on the sub-terminal device of this lingerie machine.

[0016] As a preferred solution of the above scheme, after the lingerie machine completes one lingerie blank, the lingerie machine sends a release signal to the PLC controller, and the PLC controller controls the first transition part and the second transition part of the corresponding temporary storage mechanism to be temporarily conducted, so that the lingerie blank enters the product conveying channel.

[0017] As a preferred solution of the above scheme, after the PLC controller receives the release signals of multiple lingerie machines at the same time, it sorts the conduction sequences of the temporary storage mechanisms of each lingerie machine that sends the release signal.

[0018] The advantages of the present invention are: quality inspectors can inspect the lingerie blanks produced by all lingerie machines without frequently walking between each lingerie machine. After finding that there are defects in the lingerie blanks, they can timely control the lingerie machine producing this lingerie blank to stop production and transmit the defect information to the corresponding sub-terminal device for the loom fixer to perform maintenance; when the loom fixer performs maintenance, the lingerie blank falls from the original cloth outlet of the lingerie machine, which is convenient for the loom fixer to observe whether there are defects in the lingerie blank nearby and confirm whether the problem is solved.

Detailed implementation mode

[0025] The technical solution of the present invention will be further described below through embodiments and in conjunction with the accompanying drawings.

[0026] Embodiment:

[0027] A production monitoring system for a lingerie machine cluster in this embodiment, as Figure 2 shown, includes a product conveying channel 10, a terminal controller 7, a collection box 6, a sub - terminal device 2, a channel conversion mechanism 3, and a temporary storage mechanism 4. The product conveying channel 10 includes a terminal discharge port and a plurality of feed ports. Each feed port is sequentially connected to the discharge pipes of each lingerie machine 1 through the temporary storage mechanism 4 and the channel conversion mechanism 3. An air suction device is provided in the product conveying channel 10 to form a negative pressure in the product conveying channel to convey the products of each lingerie machine to the collection box 6 at the terminal discharge port; the terminal controller 7 is arranged near the terminal discharge port and is used to separately control each lingerie machine 1 to stop work and transmit product defect information to the corresponding sub - terminal device 2; the sub - terminal device 2 is located near each lingerie machine 1 and corresponds to the lingerie machine 1 one by one. The sub - terminal device 2 includes a display screen and control buttons. The display screen is used to display the product problem information received from the terminal controller, and the control buttons are used to control the corresponding temporary storage mechanism, channel conversion mechanism, and display screen.

[0028] As Figure 3As shown in the figure, the channel conversion mechanism 3 includes a three-way joint 31, a first baffle 34, a first cylinder 35, a second baffle 32 and a second cylinder 33. The first end of the three-way joint 31 is connected to the discharge pipe 9 of the underwear machine, the second end is connected to the temporary storage mechanism, and the third end is connected to the original fabric outlet 5 of the underwear machine. The first baffle 34 is arranged at the second end of the three-way joint 31, and the second baffle 32 is arranged at the third end of the three-way joint. The first baffle 34 is driven by the first cylinder 35, and the second baffle 32 is driven by the second cylinder 33. When the second cylinder 33 extends and the first cylinder 35 contracts, the second baffle 32 blocks the third end of the three-way joint 31, and the three-way joint 31 is communicated with the temporary storage mechanism. At this time, the underwear blank produced by the underwear machine cannot fall through the original fabric outlet 5 of the underwear machine and can only enter the temporary storage mechanism. When the second cylinder 33 contracts and the first cylinder 35 extends, the third end of the three-way joint 31 is communicated with the original fabric outlet 5 of the underwear machine, and the three-way joint 31 is disconnected from the temporary storage mechanism. At this time, the underwear blank produced by the underwear machine can only fall through the original fabric outlet 5 of the underwear machine.

[0029] The temporary storage mechanism includes a first transition part 41, a second transition part 42, a third baffle 44 and a third cylinder 43. Both the first transition part 41 and the second transition part 42 are frustum-shaped, with the smaller area end as the first end and the larger area end as the second end. The first end of the first transition part 41 is connected to the second end of the three-way joint 31 in the channel conversion mechanism 3, the second end of the first transition part 41 is connected to the second end of the second transition part 42, and the first end of the second transition part 42 is connected to the feed port of the product conveying channel. The third baffle 44 is arranged at the connection between the first transition part and the second transition plate, and the third baffle 43 is driven by the third cylinder. The first transition part 41 is provided with a first through hole on its side surface. The first through hole is connected to the air suction valve controller 12 of the underwear machine through a first air suction pipe 13. A first grid fence matching the inner wall of the first transition part is arranged in the first transition part. When the third cylinder contracts, the third baffle contracts, and the first transition part 41 is communicated with the second transition plate 42, and the underwear blank can enter the product conveying channel. When the third cylinder extends, the third baffle extends to cut off the first transition part 41 and the second transition part 42, and the underwear blank cannot enter the product conveying channel. When the three-way joint 31 communicates the discharge pipe 9 and the temporary storage mechanism, and the third baffle cuts off the first transition part and the second transition part, after the exhaust fan runs, a negative pressure is formed at the first transition part 41. After the underwear machine produces an underwear blank, the underwear blank is sucked into the first transition part under the action of the negative pressure, and the first grid fence can prevent the underwear blank from entering the first air suction pipe 13.

[0030] The third cylinder in each temporary storage mechanism is connected to the output end of the PLC controller. The input ends of the PLC controller are respectively connected to each underwear machine. When the existing underwear machine finishes one underwear embryo, it will send an underwear embryo completion signal. After receiving the underwear embryo completion signal, the PLC controls the third cylinder to conduct the first transition part and the second transition part, so that the underwear embryo can enter the product conveying channel. When multiple underwear machines send underwear embryo completion information signals at the same time, the PLC will sort the conduction sequences of the corresponding temporary storage mechanisms to ensure that only one underwear embryo enters the product conveying channel at the same time.

[0031] As Figure 4 As described above, the terminal controller 7 includes a host 71, a remote controller 72 and an underwear machine operation status panel 73. The underwear machine operation status panel 73 is provided with indicator lights corresponding to the number of underwear machines. The status of the indicator lights corresponds to the operation status of the underwear machines. When the underwear machine stops working, the corresponding indicator light lights up. The remote controller 72 is used to control the stop of each underwear machine 1 and is also used to control the conduction state of the channel conversion mechanism 3. When the remote controller 72 controls a certain underwear machine 1 to stop working, it simultaneously controls the channel conversion mechanism corresponding to the underwear machine 1 to conduct the discharge pipe 9 and the cloth outlet 5 of the underwear machine 1, so that the underwear embryo produced by the underwear machine cannot enter the product conveying channel. At the same time, in order to avoid repeated operations, when the remote controller controls a certain underwear machine to stop working, the remote controller cannot control the underwear machine again until the blocker operates on the sub-terminal device corresponding to the underwear machine. The host 71 communicates with the sub-terminal devices 2 corresponding to each underwear machine and can send information to each sub-terminal device 2 separately. When the quality inspector finds a defect on a certain underwear embryo, the underwear machine that produces the underwear embryo is determined through the machine number on the underwear embryo. The remote controller 72 is used to control the underwear machine to stop working and cut off the connection between the underwear machine and the product conveying channel. At the same time, the defect information of the underwear embryo is input through the host and sent to the sub-terminal device. The defect information of the underwear embryo includes broken lines, horizontal lines, etc. It should be noted that the underwear embryo produced by the underwear machine needs to be cut to remove the excess fabric before becoming a real underwear, and the machine number is woven on the fabric that needs to be cut when the underwear machine produces the underwear embryo. Each underwear machine has its own unique machine number.

[0032] In this embodiment, there are three control buttons in the sub-terminal device 2, namely the cancellation key, the release key and the channel conversion key. The release key can control the third cylinder in the temporary storage mechanism 4 and can manually release the underwear embryo in the temporary storage mechanism 4. The cancellation key can cancel the information displayed on the display screen in the sub-terminal device 2. After the information on the message display screen is cancelled, the remote controller of the terminal controller 7 resumes the control right of the underwear machine corresponding to the sub-terminal device, and at the same time the channel conversion mechanism connects the discharge pipe of the underwear machine and the temporary storage mechanism. The channel conversion key is used to separately control the conduction state of the channel conversion mechanism, which is convenient for the staff to inspect the products of the underwear machine on site.

[0033] Correspondingly, this embodiment further provides a method for monitoring the cluster production of underwear machines. Using the above-mentioned underwear machine cluster production monitoring system, as Figure 5 shown, it includes the following steps:

[0034] S1: After the underwear machine completes the underwear blank, the product conveying channel conveys the underwear blanks produced by each underwear machine to the terminal discharge port; after the underwear machine completes the underwear blank, the underwear machine sends a release signal to the PLC controller, and the PLC controller controls the temporary conduction of the first transition part and the second transition part of the corresponding temporary storage mechanism, so that the underwear blank enters the product conveying channel. After the PLC controller receives the release signals of multiple underwear machines at the same time, it sorts the conduction sequences of the temporary storage mechanisms of the underwear machines that send the release signals.

[0035] S2: Inspect each underwear blank coming out of the terminal discharge port. If a flaw is found in the underwear blank, determine the underwear machine that produced the underwear blank according to the machine number on the underwear blank, control the underwear machine to stop working through the terminal controller, and send the flaw information of the underwear blank to the corresponding sub-terminal device, and enter step S3; when the underwear machine stops working, the indicator light corresponding to the operating status panel of the underwear machine lights up, and at the same time, the first baffle closes the second end of the three-way joint, and the second baffle retracts to connect the underwear machine discharge pipe and the original cloth outlet; after the terminal controller controls the underwear machine to stop, it cannot control the underwear machine until the fitter eliminates the flaw information of the underwear machine on the sub-terminal device of the underwear machine.

[0036] S3: The fitter repairs the underwear machine according to the flaw information displayed on the sub-terminal device. After the repair, start the underwear machine, check whether there is a flaw in the underwear blank falling from the original cloth outlet of the underwear machine. If there is a flaw, repair it again. If not, use the control button to make the second baffle close the third end of the three-way joint, and the first baffle retracts to conduct the discharge pipe and the temporary storage mechanism, so that the underwear blank can enter the temporary storage mechanism, and at the same time, eliminate the flaw information displayed on the sub-terminal device and turn off the indicator light corresponding to the underwear machine.

[0037] In the underwear machine cluster production monitoring system and method of this embodiment, the quality inspector can inspect the underwear blanks produced by all underwear machines without having to walk around frequently between each underwear machine. After finding a flaw in the underwear blank, the underwear machine that produced the underwear blank can be controlled to stop working in time and the flaw information can be transmitted to the corresponding sub-terminal device for the fitter to repair; when the fitter is repairing, the underwear blank falls from the original cloth outlet of the underwear machine, which is convenient for the fitter to observe whether there is a flaw in the underwear blank nearby and confirm whether the problem is solved.
