Description

Technical Field

[0001] The invention belongs to the field of down filling machines and down filling methods, and in particular relates to an intelligent down filling machine utilizing a flow pulse down filling method and a weighing down filling method, an intelligent down filling method and a production execution system thereof. Background Art

[0002] The existing filling method usually uses a flow filling machine for flow filling and a weighing filling machine for weighing filling. In the flow filling method, the filling time is generally calculated in advance by the system to fill the down of a given gram weight, that is, the corresponding gram weight of the down needs to spray the corresponding gram weight of gas for a continuous jet time. However, this jet method has a large error when filling large gram weight down. The reason is that when filling down, the jet head will carry the down at the down outlet and spray it out. The filling mixing box can only stir the down in the down bin to replenish the down outlet. There is a time difference in replenishment. During the replenishment process, the density of the down at the down outlet is less than the average density of the filling mixing box, which causes errors in the accuracy of the filling. The weighing filling method is more used for small gram weight filling, and it is not suitable for large gram weight filling. For example, when a down jacket cover needs to be filled, the down jacket will be divided into sleeve parts, hat parts, body parts and other parts, and the down channel widths of these parts may be different. Therefore, a down jacket will require both a flow filling machine and a weighing filling machine.

[0003] Moreover, due to the different densities of different fabrics, the required filling time is also different. It is difficult for the system to accurately calculate the correct filling time. Manual filling operations are often required when filling each pile channel, and it is impossible to fill the pile channel at one time, which is time-consuming and labor-intensive.

[0004] To this end, it is necessary to provide an economical and effective down filling machine, an intelligent down filling method and a production execution system thereof, which can perform both flow filling and weight filling, and can solve the problem of inaccurate filling weight in the flow mode for filling large gram weights, and no down coming out in the weighing mode for filling small gram weights. The structure of one nozzle corresponding to one touch screen can realize the switching of the flow mode and the weighing mode of the whole machine, and can realize the simultaneous use of the flow mode and the weighing mode to fill the same garment fabric; and it is necessary to determine the filling time through the intelligent down filling system for accurate filling to improve work efficiency. Summary of the invention

Moreover, the intelligent down filling system determines the actual down filling time corresponding to the fabric to be filled through the first down filling test, and accurately fills the subsequent down channels by adjusting the subsequent down filling time, saving manual operation procedures and improving work efficiency.

[0016] Preferably, the center of the baffle is coaxial with the agitator.

[0017] Preferably, the down filling machine comprises a down filling stirring box, and both sides of the down filling stirring box are respectively provided with a down filling control system.

[0018] Furthermore, according to the user's operation on the control component, the down filling machine has three down filling modes: weighing mode, flow mode and mixed filling mode;

[0019] In weighing mode, the control component controls the outlet of the pile channel converter to correspond to the weighing component, the weighing pile filling nozzle discharges pile, and the flow filling nozzle does not discharge pile;

[0020] In the flow mode, the control component controls the outlet of the pile channel converter to correspond to the flow filling nozzle, the flow filling nozzle discharges pile, and the weighing filling nozzle does not discharge pile;

[0021] In the mixed filling mode, the control component controls the outlet of the pile channel converter to correspond to the flow filling nozzle, the flow filling nozzle discharges the pile, and the weighing filling nozzle discharges the pile.

[0022] A down filling method using the down filling machine, the down filling machine mainly comprising a down filling stirring box and a down filling control system; the down filling control system comprises a down filling component, a workbench and a control component; the method comprises:

[0023] Step 1: The production execution system allocates the fabric to be filled with down to the corresponding workbench according to the preset process, manually inserts the weighing filling nozzle and the flow filling nozzle into the filling port of the down channel of the fabric to be filled with down, obtains the filling table information preset in the production execution system in the control component and extracts the filling initial value corresponding to the current fabric to be filled with down in the control component; the user selects whether to turn on the weighing filling nozzle and / or the flow filling nozzle on the touch screen of the control component according to the obtained initial value; wherein the filling table includes the filling information of all material components that need to be filled at the current workstation; the initial value includes the initial value of the maximum down channel gram weight, the initial value of the minimum down channel gram weight, the initial value of the minimum filling time and the initial value of the maximum filling time;

[0024] Step 2: randomly setting a down weight as a preset down weight, the control component calculates a corresponding down filling time as the preset down filling time, and then performs a first down filling test;

[0025] Step 3: The control component starts the agitator of the down filling stirring box, and the external down filling pipe starts to feed down into the down inlet. After the down filling material enters the upper box through the down inlet, it falls into the lower box and then enters the down filling component;

[0026] Step 4: The control component controls the down filling component to fill down into the down channel of the fabric to be filled with down. When the preset down filling time is over, the down filling component stops working, and the external down filling tube stops feeding down into the down inlet.

[0027] Step 5: The workbench weighs the current fabric weight, and the control component determines whether the actual filling weight is consistent with the preset filling weight; if they are consistent, the preset filling time is used as the filling time of other pile channels of the fabric to be filled, and the user inserts the weighing and flow filling nozzle into the filling port of the pile channel of other fabrics to be filled, and returns to step 3 to continue filling the remaining pile channels of the fabric to be filled until the fabric is filled and moved out of the workbench; otherwise, the touch screen in the control component prompts that the weight of the corresponding pile channel is incorrect, and the user manually controls the filling time to fill the pile; then, the control component calculates the filling time of the pile channel according to the actual filling weight before filling, the preset filling time and the initial value corresponding to the fabric to be filled according to the following formula:

[0028] T pre =(T max / g max +T min / g min ) / 2×g act (1)

[0029] Among them, T pre T is the filling time of the velvet channel. max is the initial value of the maximum filling time, g max is the initial value of the maximum velvet weight, T min is the minimum initial value of filling time, g min is the minimum initial value of velvet weight, g act It is the actual filling weight;

[0030] The control component uses the calculated down filling time as the preset down filling time for the next down filling, and returns to step 3 to continue the down filling operation until the fabric is finished being filled and moved out of the workbench.

[0031] In step 3, before the filling material enters the filling component, the step further includes: when the light sensor located on the side wall of the lower box detects that the material is accumulated to its horizontal position, a signal is sent to the control component, and the control component instructs the baffle to cover the opening.

[0032] Furthermore, in step 4, “the control component controls the filling component to fill the down channel of the fabric to be filled with down” specifically includes:

[0033] When the user only chooses to open the weighing filling nozzle, the control component controls the outlet of the pile channel converter to correspond to the weighing component, the weighing filling nozzle discharges the pile, and the flow filling nozzle does not discharge the pile. At this time, the control component controls the outlet of the pile channel converter to correspond to the weighing component, and the filling material enters the corresponding inlet of the weighing component from all the outlets of the filling mixing box through the pile channel converter / filling pipe. The weighing component weighs the filling material at the same time. When the weight of the filling material reaches the preset value of the control component, the control component controls the flow control valve group to open, driving the filling material in the weighing component to enter the filling pipe from the outlet of each weighing component. The filling pipes are merged and connected to the weighing filling nozzle to fill the pile channel;

[0034] When the user only chooses to open the flow filling nozzle, the control component controls the outlet of the pile channel converter to correspond to the flow filling nozzle, the flow filling nozzle discharges the pile, and the weighing filling nozzle does not discharge the pile. At this time, the control component controls the outlet of the pile channel converter to correspond to the inlet of the flow filling nozzle, and the filling material enters the inlet of each flow filling nozzle from the outlet of the filling mixing box through the pile channel converter to fill the pile channel;

[0035] When the user chooses to open the weighing filling nozzle and the flow filling nozzle at the same time, the control component controls the outlet of the pile channel converter to correspond to the flow filling nozzle, the flow filling nozzle discharges the pile, and the weighing filling nozzle discharges the pile. At this time, the outlet of the pile channel converter corresponds to the inlet of the flow filling nozzle, and the filling material enters the inlet of each flow filling nozzle through the pile channel converter from at least one pile outlet of the filling mixing box, and fills the pile channel. At the same time, the filling material enters the inlet of the corresponding weighing component through the filling pipe from the remaining pile outlets of the filling mixing box for weighing. The weighing component weighs the filling material at the same time, and then the filling material enters the filling pipe from the outlet of each weighing component. The filling pipes are connected to the weighing filling nozzle after merging, and the filling channel is filled with pile.

[0036] A production execution system for executing the down filling machine, wherein the operating unit of the production execution system is the down filling machine. The production execution system further comprises: a confirmation unit, which is used to receive the fabric to be filled with down identified by the control component, and to correspond the category of the fabric to be filled with down to the initial value set by itself, and to send the initial value to the control component.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The filling machine combines the two modes of flow filling and weighing filling in one. A set of filling components can be used to complete flow filling and weighing filling. The structure of one nozzle corresponding to one touch screen can realize the switching of the flow mode and weighing mode of the whole machine, and the same fabric can be filled in the flow mode and weighing mode at the same time.

[0039] 2. For fabrics to be filled with down of the same density, the filling condition of the first fabric is tested, and the subsequent filling time is adjusted to accurately fill the subsequent down channels, which effectively improves work efficiency and solves the problems of inaccurate filling weight with large gram flow rate and no down filling with small gram weight.

The purpose of such a configuration is to fill the fabric with down on both sides at the same time, which is conducive to improving work efficiency.

[0057] Embodiment 2:

[0058] Figure 3 The embodiment 2 is different from the embodiment 1 in that the down filling machine is a down filling stirring box, and a down filling control system is arranged on one side of the down filling stirring box.

[0059] When the site space is limited or according to processing needs, the filling control system can be set up on only one side.

[0060] A down filling method using the down filling machine, the down filling machine mainly comprises a down filling stirring box and a down filling control system; the down filling control system comprises a down filling component, a workbench and a control component; the method is specifically as follows:

[0061] Step 1: The preset MES system (manufacturing operation management system) will allocate raw materials, such as fabrics to be filled, to corresponding workstations (the workstations correspond to corresponding workbenches 10) according to the preset procedures, and manually insert the weighing filling nozzle 9 and the flow filling nozzle 7 into the filling port of the fabric to be filled. When the MES system pushes the fabric to be filled to the filling station, the user clicks the "Get Filling Table" button on the touch screen of the control component 8 of the filling machine. At this time, the control component of the filling machine will grab the filling table of all material parts that need to be filled on the workbench 10 from the MES system, and According to the component name displayed in the filling machine interface, the user only needs to select the filling component, and the filling weight of the component will be automatically added to the filling table of the filling machine. The user obtains the filling table information and extracts the filling initial value corresponding to the current fabric to be filled; then the user selects whether to turn on the weighing filling nozzle 9 and / or the flow filling nozzle 7 on the touch screen of the control component 8 according to the obtained initial value; wherein, the filling table includes the filling information of all material components that need to be filled at the current station; the initial value includes the maximum pile weight initial value, the minimum pile weight initial value, the minimum filling time initial value and the maximum filling time initial value;

[0062] Among them, the production execution system described in this embodiment is an MES system, the operating unit of the MES system is a filling machine, and the confirmation unit of the MES system is used to receive the fabric to be filled identified by the control component 8, and correspond the category of the fabric to be filled with the initial value set by itself, and send the initial value to the control component.

[0063] Step 2: To determine whether the initial value obtained in the previous step is accurate, a pile weight is randomly set as the preset weight, and the control component 8 calculates the corresponding filling time as the preset filling time, and then performs the first filling test.

[0064] Step 3: The control component 8 starts the agitator 4 of the down filling mixing box 1. At this time, the baffle between the upper box body and the lower box body is not closed. The down filling material enters the upper box body through the down inlet 3, falls into the lower box body, and then enters the down filling component; the two agitators 4 stir the down filling material to keep the material in the down filling mixing box 1 fluffy at all times. When the photo sensor located on the side wall of the lower box body detects that the material is accumulated to the horizontal position of the photo sensor, it sends a signal to the control component, and the control component instructs the baffle 5 to cover the opening to prevent excessive down from falling from the lower box body and clogging the down filling tube.

[0065] Step 4: The control component controls the filling component to fill the down channel of the fabric to be filled with down. When the preset filling time is over, the filling component stops working, and the external filling tube stops feeding down into the down inlet. Specifically, according to Figure 2 As shown:

[0066] When the user only chooses to open the weighing filling nozzle 9, the two flow filling nozzles 7 do not work, and only the weighing filling nozzle 9 performs the filling of the down channel. At this time, the control component 8 controls the outlet of the down channel converter 14 to correspond to the weighing component 13, and the filling material enters the corresponding four inlets of the weighing components 13 from the four down outlets 16 of the down filling mixing box 1 through the down channel converter 14 / down filling pipeline 11. The four weighing devices weigh the filling material at the same time. When the weight of the filling material in the four weighing devices reaches the preset value of the PLC controller, the four compressed air solenoid valves controlled by the PLCC controller are opened in turn, and the compressed air flows into the vacuum flow valve. The vacuum flow valve generates a vacuum airflow, which drives the filling material in the weighing component to enter the filling pipeline from the outlet of each weighing component. The four-way filling pipelines are connected to the weighing filling nozzle to fill the down channel until the filling is completed and enter the next step.

[0067] When the user only chooses to open the flow filling nozzle 7, as shown in the figure, the weighing filling nozzle 9 in the middle does not work, and only the two outermost flow filling nozzles 7 perform the filling of the pile channel. At this time, the control component 8 controls the outlet of the pile channel converter 14 to correspond to the inlet of the flow filling nozzle 7, and the filling material enters the inlet of each flow filling nozzle 7 from the outermost pile outlet 16 of the filling mixing box 1 through the pile channel converter 14 to fill the pile channel until the filling is completed and enters the next step.

[0068] When the user chooses to open the weighing filling nozzle 9 and the flow filling nozzle 7 at the same time, the two flow filling nozzles 7 and the one weighing filling nozzle 9 are both working. The outlet of the pile channel converter 14 corresponds to the inlet of the flow filling nozzle 7, and the filling material enters the inlet of each flow filling nozzle 7 from the two outermost pile outlets 16 of the filling mixing box 1 through the pile channel converter 14 to fill the pile channel, and at the same time, the filling material enters the inlet of the two weighing components 13 located in the middle through the filling pipe 11 from the two pile outlets in the middle of the filling mixing box 1 for weighing. When the weight of the filling material in the two weighing devices reaches the preset value of the PLC controller, the PLC controller controls the two corresponding compressed air solenoid valves to open in sequence, and the compressed air flows into the vacuum flow valve, and the vacuum flow valve generates a vacuum airflow, driving the filling material in the weighing component to enter the filling pipe 11 from the outlet of each weighing component 13, and the two filling pipes 11 are combined and connected to the weighing filling nozzle 9 to fill the pile channel until the filling is completed and enters the next step.

[0069] Step 5: The workbench 10 weighs the current fabric weight, and the control component 8 determines whether the actual filling weight is consistent with the preset filling weight; if they are consistent, the preset filling time is used as the filling time of the remaining pile channels of the fabric to be filled, and the user inserts the weighing filling nozzle 9 and the flow filling nozzle 7 into the filling ports of the pile channels of other fabrics to be filled, and returns to step 3 to continue filling the remaining pile channels of the fabric to be filled until the fabric is filled and moved out of the workbench; otherwise, the touch screen in the control component prompts that the weight of the corresponding pile channel is incorrect, and the user manually controls the filling time to fill the pile; then, the control component 8 calculates the filling time of the pile channel according to the actual filling weight before filling, the preset filling time and the initial value corresponding to the fabric to be filled according to the following formula:

[0070] T pre =(T max / g max +T min / g min ) / 2×g act (1)

[0071] Among them, T pre T is the filling time of the velvet channel. max is the initial value of the maximum filling time, g max is the initial value of the maximum velvet weight, T min is the minimum initial value of filling time, g min is the minimum initial value of velvet weight, g act It is the actual filling weight;

[0072] The control component 8 uses the calculated down filling time as the preset down filling time for the next down filling, and returns to step 3 to continue the down filling operation until the fabric is finished being filled and moved out of the workbench.

[0073] Although the present invention has been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can make many modifications without departing from the purpose of the present invention, all of which are within the protection of the present invention.
