Description

Technical Field

[0001] This application relates to the technical field of weighted clothing production, and particularly to a filling system and its usage method. Background Art

[0002] In traditional weighted clothing material filling, the method of filling one by one manually is mostly adopted, which belongs to a labor-intensive production line. Due to the diverse specifications of weighted clothing, there are significant differences in the material formula and gram weight filled for different specifications. For the same specification of weighted clothing and on both sides of the same weighted clothing, high precision is required for the filling amount. Also, since the filling mostly uses a mixed material of fine-grained iron sand and ore sand, there is a dust problem. This results in a high labor intensity for workers, a poor working environment, low production efficiency, and the product quality being completely dependent on humans. In this regard, considering how to effectively improve the working environment, increase production efficiency, reduce production costs, and achieve automated production while ensuring the filling quality of weighted clothing has become the technical background factor driving the continuous development and improvement of the weighted clothing filling unit.

[0055] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0057] To facilitate the understanding of the filling system provided by the embodiment of the present application, its application scenario will be described first. The filling system provided by the embodiment of the present application is applied to weighted vests or other products that need to be filled with filling materials. In the traditional filling of weighted vest materials, the method of filling one by one manually is mostly used, which has problems such as dust, and at the same time causes great labor intensity of the staff, poor working environment, low production efficiency, and the product quality completely depends on people. For this reason, the embodiment of the present application provides a filling system to improve the production efficiency of weighted vests. The filling system provided by the embodiment of the present application will be described in detail below with reference to specific drawings and embodiments.

[0058] Refer to Figure 1 as shown in Figure 1The structural schematic diagram of the filling system provided by the embodiments of the present application is shown. The filling system provided by the embodiments of the present application mainly includes a feeding unit 20, a weighing unit 30, a conveying unit 40, and a filling unit 10. Among them, the feeding unit 20 is used to provide the filling material for filling; the weighing unit 30 is used to weigh the required filling material; and the conveying unit 40 is used to convey the filling material to the filling unit 10, and the filling unit 10 is used to fill the load-bearing clothing. The following will be described in detail with specific drawings and embodiments.

[0059] The feeding unit 20 provided by the embodiments of the present application is used to provide the required filling material. In an implementable solution, the feeding unit 20 can be used to transfer the packaged filling material and can unpack the filling material so that the filling material can enter the weighing unit 30 for weighing.

[0060] The weighing unit 30 provided by the embodiments of the present application is used to weigh the filling material. In use, the unpacked filling material from the feeding unit 20 can fall into the weighing unit 30 for weighing. When the filling material from the feeding unit 20 falls into the weighing unit 30, the weighing unit 30 weighs it. After the weighing unit 30 weighs the required filling material, the feeding unit 20 stops feeding the weighing unit 30.

[0061] The conveying unit 40 is used to transfer the filling material weighed by the weighing unit 30 into the filling unit 10. In specific settings, the conveying unit 40 includes a conveying component 500500 and a tipping and discharging device 600. Among them, the conveying component 500500 is used to convey the filling material from the weighing unit 30 to the tipping and discharging device 600, and the tipping and discharging device 600 fills the conveyed filling material into the filling unit 10 by tipping. As Figure 3 shown, in specific settings, the conveying component 500500 includes a conveying line 520 and an aggregate hopper 510 carried on the conveying line 520. The aggregate hopper 510 is used to carry the filling material weighed by the weighing component. In use, the aggregate hopper 510 and the conveying line 520 are arranged in a separable manner. The aggregate hopper 510 is only carried by the conveying line 520, and the two are detachably connected (such as snap connection or other detachable connection methods). When the aggregate hopper 510 is located below the weighing unit 30, the filling material weighed by the weighing unit 30 can fall into the aggregate hopper 510, and the conveying line 520 conveys the aggregate hopper 510 carrying the filling material to a set position, which is the position where the aggregate hopper 510 cooperates with the tipping and discharging device 600. The tipping and discharging device 600 is used to transfer the filling material in the aggregate hopper 510 at the set position to the filling unit 10, so as to convey the filling material from the weighing unit 30 to the filling unit 10.

[0062] Refer to together Figure 5 andFigure 6 , Figure 5 shows a schematic structural diagram of the filling unit 10 provided by an embodiment of the present application, Figure 6 and shows a schematic structural diagram of the filling assembly. The filling unit 10 includes a filling assembly and a gas supply unit. The filling assembly is used to carry the filling material filled by the tipping discharging device 600 and to convey the filling material to the filling area of the load-bearing garment. When filling the filling material, it is filled by its own weight. The gas supply unit is used to supply gas to the filling area of the load-bearing garment to facilitate the filling of the filling material. At the same time, the gas supply unit is also used to supply gas to the filling assembly to facilitate the falling of the filling material.

[0063] Specifically, the filling assembly includes a barrel assembly and a filling head. Among them, the barrel assembly is used to carry the filling material transferred by the tipping discharging device 600, and the filling head is connected to the barrel assembly to provide a channel for the filling material to be filled into the filling area of the load-bearing garment. When the filling head is in use, the filling head is inserted into the filling area of the load-bearing garment.

[0064] In a specific example, the feeding end of the barrel assembly 110 is a closable feeding end. When feeding is required, the feeding end of the barrel assembly 110 can be opened; after feeding is completed, the feeding end of the barrel assembly 110 can be closed. When using the closable barrel assembly 110, it is possible to reduce the entry of external impurities into the filling area of the load-bearing garment along with the filling material, ensuring the cleanliness of the filling material, and at the same time reducing the volatilization of the filling material and reducing the dust in the environment.

[0065] The filling head 130 is connected to the barrel assembly 110 and is used to convey the filling material contained in the barrel assembly 110 to the filling area of the load-bearing garment. As Figure 7 shown, Figure 7 shows a schematic structural diagram of the filling head. Specifically, the filling head 130 includes a filling pipe 131 and an air inflation pipe 132 surrounding the filling pipe 131. Among them, the filling pipe 131 is connected to the barrel assembly 110, and the air inflation pipe 132 is connected to the gas supply unit 200. In addition, the gas supply unit 200 is also connected to the barrel assembly 110.

[0066] During specific connection, the filling head 130 includes a filling pipeline 131 communicating with the barrel assembly 110 and an inflation pipeline 132 located in the filling pipeline 131. The inflation pipeline 132 is connected to a gas supply pipeline 120, and the gas supply pipeline 120 also communicates with the barrel assembly 110. That is, when the gas supply pipeline 120 supplies gas, it can supply gas to the inflation pipeline 132 and the barrel assembly 110 respectively. In one example, the gas supply pipeline 120 communicates with the gas supply assembly 210 of the gas supply unit 200, so that the gas supply assembly 210 supplies gas to the inflation pipeline 132 and the barrel assembly 110 through the gas supply pipeline 120. When the structure of the inflation pipeline 132 located in the filling pipeline 131 is adopted, the filling pipeline 131 wraps the inflation pipeline 132, so that after the inflation pipeline 132 inflates the filling area, the filling material can be filled from the filling head 130 into the filling area. In addition, the inflation pipeline 132 and the filling pipeline 131 are coaxially arranged, so that the gas and the material are synchronous and do not affect each other during the conveying process, improving the filling and filling efficiency.

[0067] During use, first insert the filling head 130 into the filling area of the load-bearing garment. Since the two layers of fabric forming the filling area are attached to each other when the filling material is not filled, the filling material cannot be filled into the filling area. That is, the outlet of the filling pipeline 131 of the filling head 130 is blocked by the two attached layers of fabric. When the filling material is assembled into the barrel assembly 110, since the filling pipeline 131 is blocked, it remains in the barrel assembly 110 and the filling pipeline 131. When filling the filling material, first supply gas through the gas supply assembly 210. The airflow is divided into two paths through the gas supply pipeline 120. One of the paths inflates the filling area of the load-bearing garment through the inflation pipeline 132, so as to separate the two attached layers of fabric. Under the action of gravity, the filling material located in the filling pipeline 131 falls into the filling area. At the same time, the other path of airflow enters the barrel assembly 110 through the gas supply pipeline 120, so as to reduce the negative pressure situation in the barrel assembly 110 caused by the falling of the filling material, ensuring that the filling material can be stably conveyed to the filling area through the filling pipeline 131. In addition, when the airflow enters the barrel assembly 110 through the gas supply pipeline 120, the filling material can also be cleaned by the airflow, ensuring that all the filling material can be filled into the load-bearing garment, avoiding the residue of the filling material, and ensuring the accuracy of the filling amount of the filling material.

[0068] As can be seen from the above solution, the filling system provided by the embodiments of the present application feeds materials through the feeding unit 20, weighs the required filling materials through the weighing unit 30, transfers the weighed filling materials to the barrel assembly of the filling unit 10 through the conveying unit 40, and when the barrel assembly inflates the load-bearing garment, the air supply unit synchronously inflates the barrel assembly and the filling area of the load-bearing garment to facilitate the filling of the filling materials into the filling area, thereby realizing the automated production of the load-bearing garment filling, improving the production efficiency, reducing the labor intensity of the workers, and at the same time, improving the qualified rate of the products compared with manual filling of the filling materials.

[0069] Refer to Figure 2 , Figure 2 shows a schematic structural diagram of the feeding unit 20 provided by the embodiments of the present application. The feeding unit 20 provided by the embodiments of the present application includes a hoisting device 310 and an unpacking device 320. Among them, the hoisting device 310 is used to hoist the material bag carrying the filling materials. The hoisting device 310 is slidably assembled on the slide rail 330 and can slide along the slide rail 330. The slide rail 330 is located above the unpacking device 320 and is parallel to the horizontal direction, so that the hoisting device 310 can move along the slide rail 330 to realize feeding. In addition, the hoisting device 310 can be lifted and lowered by a hoist so that the packaging bag carrying the filling materials can be lowered onto the unpacking device 320 for unpacking. The unpacking device 320 has a bin 321 that can carry the filling materials after unpacking. The bin 321 is located above the weighing unit 30 and can supply materials to the weighing unit 30. In an implementation scheme, the bin 321 has a discharge pipeline, and a feeder 322 is provided on the discharge pipeline.

[0070] Refer to Figure 2 and Figure 3 , Figure 3 shows a schematic diagram of the cooperation between the weighing unit 30, the feeding unit 20 and the conveying unit 40 provided by the embodiments of the present application. The weighing unit 30 includes an electronic scale 410 and a container 420 placed on the electronic scale 410. The container 420 is used to carry the filling materials flowing out of the discharge pipeline of the unpacking device 320. The filling materials are weighed by the electronic scale 410. In addition, the container 420 also has a discharge port, which is used to convey the filling materials to the aggregate hopper 510 in the conveying unit 40. Among them, a control valve is also provided at the discharge port to control the opening and closing of the discharge port.

[0071] In use, first, the hoisting device 310 moves the material bag carrying the filling material above the unpacking device 320. The hoisting device 310 descends, and the unpacking device 320 unpacks the material bag, and the filling material falls into the unpacking device 320. The feeder 322 of the unpacking device 320 is opened, and the filling material falls into the container 420 of the weighing unit 30. After the electronic scale 410 weighs the required filling material, the feeder 322 on the unpacking device 320 is closed, and the control valve at the discharge port of the container 420 is opened, and the filling material falls into the aggregate hopper 510 on the conveying line 520, so as to realize the transfer of the filling material from the feeding unit 20 to the conveying unit 40.

[0072] Refer to together Figure 4 , Figure 4 shows a schematic structural view of the tipping discharging device 600 provided by an embodiment of the present application. The tipping discharging device 600 provided by an embodiment of the present application includes a support column 610 and a clamping assembly. Among them, the support column 610 is arranged in the height direction, and a rack 630 is arranged on the support column 610, and the length direction of the rack 630 is also in the vertical direction. The clamping assembly includes a support block 621 and a clamping member 622. The support block 621 is slidably connected to the support column 610, and a driving gear 623 is rotatably connected to the support block 621, and the driving gear 623 meshes with the rack 630. The clamping member 622 is fixedly connected to the driving gear 623, and the clamping member 622 is used for clamping the aggregate hopper 510. When the support block 621 slides relative to the support column 610, the driving gear 623 rotates relative to the rack 630, thereby driving the clamping member 622 to rotate relative to the support block 621. By setting an appropriate tooth speed ratio, when the support block 621 slides to a position, the clamping member 622 is located at a position matching the aggregate hopper 510 on the conveying line 520, and when the support block 621 slides to another position, the clamping member 622 rotates to a position matching the cartridge assembly.

[0073] In an implementable solution, the support block 620 can be driven to slide by a driving motor. For example, the driving motor drives the support block 620 to slide through a synchronous belt, or drives the support block 620 to slide through a lead screw assembly.

[0074] In an implementable solution, the clamping member 650 can adopt a clamping structure. And the two opposite arc-shaped structures of the clamping member 650 can be driven to open and close by a cylinder to realize clamping or releasing the aggregate hopper 510.

[0075] In a specific implementable solution, the clamping member 650 can be fixedly connected to the driving gear 640 through a support arm, so that when the clamping member 650 rotates relative to the support column 610, a swinging effect can be realized.

[0076] It should be understood that when the above-mentioned feeding unit 20, weighing unit 30, and conveying unit 40 are specifically arranged, there are multiple unpacking devices 320 in the feeding unit 20 to carry different filling materials, and the weighing unit 30 and the conveying unit 40 can be used in a one-to-one correspondence with the unpacking device 320 to ensure that each filling material can be weighed and conveyed. When the filling materials need to be mixed before filling, two or more unpacking devices 320 can also correspond to one weighing unit 30. At this time, filling materials of different types or different particle sizes are fed to the same weighing unit 30.

[0077] To facilitate the coordination of the above-mentioned feeding unit 20, weighing unit 30, conveying unit 40 and filling unit 10, the filling system provided in the embodiment of the present application also includes a control device, which is used to control at least some of the above-mentioned units to realize the automatic operation of the controlled units.

[0078] In one example, the silo 321 in the feeding unit 20 has a sensor for detecting the material level (such as a rotary resistance material level, a solid tuning fork material level meter, etc.), and when the sensor detects that the material level is normal, the silo 321 supplies materials normally. When the material level is abnormal, that is, when there is less filling material in the silo 321, the control device controls the alarm device to sound an alarm, and the control device controls the feeding unit 20 to stop feeding the weighing unit 30, and at the same time, controls the lifting device 310 to lift the material package to the unpacking device 320 for unpacking until the material level in the silo 321 is normal.

[0079] In one example, the control device can compare the weight fed back by the weighing unit 30 with the first set weight. If the weight fed back by the weighing unit 30 is less than the first set weight, the feeding unit 20 is controlled to feed at high speed; if the weight fed back by the weighing unit 30 is greater than the first set weight, the feeding unit 20 is controlled to feed at variable frequency. Specifically, according to the feeding characteristics of the feeder 322, the weighing process can be divided into the initial weighing period and the final weighing period in the weighing time domain, with the purpose of matching the weighing algorithm so that the working state of the feeder 322 changes with the weighing curve. Among them, when the weight fed back by the weighing unit 30 is less than the first set weight, it is the initial weighing period, and the feeder 322 runs fast and has a strong feeding capacity. As the weighing process enters the final weighing period (the weight fed back by the weighing unit 30 is greater than the first set weight), the running state of the feeder 322 is controlled by the weighing curve, and its running speed is gradually reduced, and the feeding capacity is correspondingly reduced to achieve accurate feeding. In the specific setting, the feeding capacity of the feeder 322 is closely related to its structure, specifications and material state, and must be matched according to actual needs. The larger the capacity, the better. For example, if a spiral feeder is required to output 6kg of gray iron ore filler within 15s, the average particle size of the filler particles is 0.8mm, in bead shape, and the feeding accuracy is controlled within ±10g, based on the above information, it can be considered to use Variable-frequency screw feeder, controlled by a weighing curve. Before the material is weighed to 5 kg, the running speed of the screw feeder is relatively fast to improve the weighing efficiency. After weighing to 5 kg, it enters the variable-frequency operation stage, and the running speed becomes lower and lower until the weighing value reaches 6 kg ± 5 g. The electronic scale 410 feeds back the weighing value to the control device in real time. The control device compares it with the weighing curve value in combination with the feedback signal, and the whole weighing process will proceed orderly in the process of gradually fitting the weighing curve. The above-mentioned weighing curve is an algorithm that compares the feedback signal and then controls when and in what state the feeder 322 should operate.

[0080] When specifically controlling the feeder, its specific control logic is as follows: X is the current real-time weighing value, Y is the target set value, and △M is the difference from the target, then △M = Y - X. The weighing curve reflects the relationship between the difference △M and the motor running frequency F, and the two satisfy △M ∝ F. Since different materials have different specific gravities and fluidities, the weighing curve will be different, which is related to the response time of the material state to the system. Therefore, the weighing curve as a whole shows a piecewise function distribution. Taking the target set value of 3 kg as an example, in the early stage of weighing, that is, when △M ≥ 1 kg, the motor runs at the power frequency, the material is discharged faster, and the discharge amount per unit time is constant; in the middle stage of weighing, that is, when 0.3 kg < △M < 1 kg, the motor gradually reduces the frequency from 50 Hz to 15 Hz; in the late stage of weighing, that is, when △M ≤ 0.3 kg, the motor gradually reduces from 15 Hz to 0 Hz, that is, the motor stops rotating and the weighing ends. The above weighing process is a control method based on the frequency domain. From the perspective of time-domain control, within a unit time, the change rate of the motor speed in the late stage of weighing is larger than that in the middle stage of weighing. The specific corresponding relationship refers to Table 1.

[0083] In an example, when the weighing unit 30 supplies materials to the conveying unit 40, the system further includes a first sensor for detecting the aggregate hopper 510 located below the weighing unit 30. The control device is further configured to control the conveyor line 520 to stop and control the weighing unit 30 to pour the filling material into the aggregate hopper 510 when the first sensor detects the aggregate hopper 510. Specifically, a first sensor is arranged below the electronic scale 410 or other positions. When the conveyor line 520 conveys the aggregate hopper 510, it is detected by the first sensor whether the aggregate hopper 510 is transported to a position matching the weighing unit 30. When the first sensor detects that the aggregate hopper 510 moves to a position matching the weighing unit 30, the conveyor line 520 is controlled to stop transporting the aggregate hopper 510, and the control valve of the weighing unit 30 is controlled to open, and the weighing unit 30 pours the weighed filling material into the aggregate hopper 510.

[0084] Continue to refer toFigure 6 As shown, when filling the weighted clothing, there may be multiple filling areas. Therefore, when setting up the filling assembly 100, the number of cartridge assemblies 110 in the filling assembly 100 is at least two, and each cartridge assembly 110 corresponds to a filling head 130 to synchronously fill different filling areas of the weighted clothing. Additionally, when there are differences in the filling amounts or materials in different filling areas of the weighted clothing, different cartridge assemblies 110 can hold cartridges 112 with different amounts or hold filling materials of different materials to meet the requirement of synchronously filling different filling areas of the weighted clothing.

[0085] Continue to refer to Figure 6 In the embodiment of the present application, the cartridge assembly 110 mainly includes a cartridge 112 and a hopper 111. Here, the hopper 111 is a component that cooperates with the tipping discharging device 600. The filling material transported by the tipping discharging device 600 is directly poured into the hopper 111. The cartridge 112 is fixedly connected to the hopper 111 and the two are in communication. The filling material poured into the hopper 111 can directly fall into the cartridge 112. The cartridge 112 is in communication with the filling head 130. Exemplarily, one end of the cartridge 112 away from the hopper 111 is connected to the filling head 130 through a flexible tube 140, and the filling pipeline 131 is in communication with the flexible tube 140, so that the filling material can directly flow into the filling pipeline 131 through the flexible tube 140. At the same time, the air supply pipeline 120 is in communication with the cartridge 112, so that when the filling material is falling, air can be supplied to the cartridge 112 to facilitate the falling of the filling material.

[0086] In an implementable solution, the flexible tube 140 is detachably connected to the filling head 130. Specifically, there is a pipeline for transmitting air in the flexible tube 140. This pipeline is in communication with the inflation pipeline 132 in the filling head 130, and the other end extends to one end of the flexible tube 140 close to the cartridge 112 and is used to connect to the air supply pipeline 120. When connecting to the air supply pipeline 120, a quick connector is connected to one end of the cartridge 112 close to the flexible tube 140, and a quick connector is also provided at one end of the flexible tube 140 close to the cartridge 112. When the air supply pipeline 120 is in communication with the cartridge 112 and the inflation pipeline 132 respectively, it can be detachably connected through the quick connector.

[0087] In an example, the flexible tube 140 can be a common flexible tube such as a hose or a snake-shaped tube. Of course, other implementable flexible tubes 140 can also be used, and no specific limitation is made in the embodiment of the present application.

[0088] In an implementable solution, the end of the cartridge 112 in communication with the flexible tube 140 adopts an inverted conical structure to facilitate the falling of the filling material.

[0089] In addition, the barrel assembly 110 further includes a one-way valve 113, which is used to seal and isolate the hopper 111 and the barrel 112. The conduction direction of the one-way valve 113 is from the hopper 111 to the barrel 112. That is, when filling materials flow from the hopper 111 into the barrel 112, under the action of the gravity of the filling materials, the one-way valve 113 opens, and the filling materials can fall from the hopper 111 into the barrel 112. After the filling materials completely fall from the hopper 111 into the barrel 112, the one-way valve 113 closes and seals the connection between the hopper 111 and the barrel 112, thereby sealing the feeding end of the barrel assembly 110. The one-way conductivity of the one-way valve 113 is fully utilized to maintain the pressure in the barrel 112 during the filling process to prevent the filling materials from flowing back.

[0090] The one-way valve 113 provided in the embodiment of the present application includes a valve body and a valve plate. The valve body is respectively connected to the barrel 112 and the hopper 111. The valve plate is rotatably connected to the valve body, and the valve plate is pressed against the valve body by the elastic force provided by a torsion spring. During use, when the filling materials fall, the filling materials push the valve plate to rotate, the valve plate opens, and the torsion spring undergoes elastic deformation. After the filling materials completely fall into the barrel 112, the valve plate rotates under the action of the torsion spring, presses against the valve body, and forms a seal. During specific sealing, a sealing gasket is provided on the valve plate or the valve body, and the sealing is achieved through the sealing gasket.

[0091] It should be understood that when the valve body is respectively connected to the barrel 112 and the hopper 111, sealing can also be performed through a sealing gasket to reduce dust.

[0092] Continue to refer to Figure 7 , the filling head 130 provided in the embodiment of the present application is a duckbill-shaped filling head 130. The inflation pipeline 132 is located in the middle area of the filling pipeline 131. When adopting the duckbill-shaped structure, the end of the filling head 130 inserted into the filling area of the load-bearing garment is flat, so as to facilitate inserting the filling head 130 into the filling area of the load-bearing garment before the load-bearing garment is filled.

[0093] Refer to Figure 6 and Figure 8 , Figure 8 shows a schematic structural diagram of another angle of the filling assembly. The filling assembly 100 provided in the embodiment of the present application further includes a barrel bracket 160, which is used to support the barrel assembly 110. During specific setting, the barrel assembly 110 is fixed on the barrel bracket 160, so as to support the barrel assembly 110 through the barrel bracket 160, so that the barrel assembly 110 can be kept stable.

[0094] In specific settings, the barrel support 160 includes two parts, one part is used to support the barrel assembly 110, and the other part is used to cooperate with the air supply unit 200. Exemplarily, the barrel support 160 includes a support cross beam 161 and a support vertical beam 162 fixedly connected to the support cross beam 161. In specific settings, the support cross beam 161 and the support vertical beam 162 form a T-shaped structure. Among them, the support cross beam 161 is used to support the barrel assembly 110, and the support vertical beam 162 is used to fix the barrel support 160 to other support devices. For example, when the filling assembly 100 is assembled on the conveyor belt, the barrel support 160 can be fixed on the conveyor belt through the support vertical beam 162. When the conveyor belt rotates, the barrel assembly 110 can be conveyed.

[0095] Continue to refer to Figure 8 As shown, the support cross beam 161 provided in the embodiment of the present application is a cross beam with a U-shaped cross section. Through holes are provided on the two cross plates of the support cross beam 161, and the through holes can be used to pass through the barrel assembly 110. In one example, the hopper 111 and the barrel 112 are connected by a connecting flange. When the barrel assembly 110 is installed on the support cross beam 161, it can be abutted against the cross plate of the support cross beam 161 through the connecting flange, so as to support the barrel assembly 110. There is no need to use a connecting piece for fastening connection between the two, and the barrel assembly 110 can be supported by the support cross beam 161. When supporting the barrel assembly 110 in the above manner, on the one hand, it is convenient for the installation of the barrel assembly 110, and on the other hand, after the barrel assembly 110 fails, the barrel assembly 110 can be directly pulled out from the support cross beam 161, which is convenient for maintenance or replacement.

[0096] It should be understood that when the number of barrel assemblies 110 in the filling assembly 100 is multiple, the multiple barrel assemblies 110 can be supported synchronously by one barrel support 160.

[0097] Continue to refer to Figure 8 As shown, the filling assembly 100 provided in the embodiment of the present application further includes a clothes hanger 150 for supporting the load-bearing garment. The clothes hanger 150 is arranged on the barrel support 160 to facilitate filling the filling material into the load-bearing garment. When in use, the load-bearing garment can be first hung on the clothes hanger 150, and then the filling head 130 can be inserted into the filling area of the load-bearing garment.

[0098] In a specific example, the clothes hanger 150 is detachably hinged to the barrel support 160 through a pin shaft, and the clothes hanger 150 can rotate relative to the barrel support 160 through the pin shaft. When adopting this method, it is convenient for workers to put the load-bearing garment on the clothes hanger 150. At the same time, it is also convenient to replace clothes hangers of different sizes according to different models of the load-bearing garment.

[0099] Refer to together Figure 5 、 Figure 8 And Figure 9, the air supply unit 200 of the filling unit 10 provided by the embodiments of the present application includes an inflation pile 220 and an air supply assembly 210. Among them, the inflation pile 220 and the filling assembly 100 can be arranged in a detachable fixed connection manner. When arranged in this way, the air supply assembly 210 of the air supply unit 200 is detachably connected to the air supply pipeline 120.

[0100] Exemplarily, the inflation pile 220 includes a column 221 and a positioning plate 223 slidably assembled on the column 221. In addition, it further includes a driving mechanism for driving the positioning plate 223 to slide. Among them, the sliding direction of the positioning plate 223 is along the vertical direction, and the positioning plate 223 is used to cooperate with the barrel bracket 160. When the positioning plate 223 slides to a set position, the positioning plate 223 is in positioning cooperation with the barrel 112 to facilitate the positioning cooperation and conduction between the air supply assembly 210 and the air supply pipeline 120.

[0101] When the positioning plate 223 is in positioning cooperation with the barrel bracket 160, a positioning block 224 is provided on the positioning plate 223, and at the same time, a positioning hole 1611 for cooperating with the positioning block 224 is provided on the barrel bracket 160. As Figure 8 shown, the positioning hole 1611 is opened on the support vertical beam 162 of the barrel bracket 160. Exemplarily, the number of positioning blocks 224 is multiple, and the number of corresponding positioning holes 1611 is also multiple to improve the stability of the positioning cooperation. As Figure 8 shown, the number of positioning holes 1611 is two, and the number of corresponding positioning blocks 224 is also two. Through the cooperation between the positioning hole 1611 and the positioning hole 240, precise positioning between the inflation pile 220 and the filling assembly 100 is achieved through non-rigid connection.

[0102] When the driving mechanism drives the positioning plate 223 to slide to the set position, the positioning block 224 is inserted into the positioning hole 1611, thereby positioning and fixing the barrel bracket 160 of the filling assembly 100 and the positioning plate 223. To facilitate positioning, when setting the positioning block 224, the end of the positioning block 224 inserted into the positioning hole 1611 adopts a conical guiding structure to facilitate alignment.

[0103] In one example, the driving mechanism can adopt a double-axis cylinder. Of course, other linear driving mechanisms can also be adopted, which will not be elaborated in the embodiments of the present application.

[0104] When the air supply assembly 210 cooperates with the air supply pipeline 120, an air supply module 222 is provided on the positioning plate 223, and a gas receiving module 163 is provided on the barrel bracket 160. Specifically, the gas receiving module 163 is fixed on the support vertical beam 162 of the barrel bracket 160. The above-mentioned air supply module 222 is communicated with the air supply assembly 210, while the gas receiving module 163 is communicated with the air supply pipeline 120.

[0105] When the positioning plate 223 slides relative to the column 221, it can drive the air supply module 222 to slide relative to the air receiving module 163 to approach or move away from the air receiving module 163. When the positioning plate 223 slides to a set position, the air supply module 222 is hermetically connected to the air receiving module 163 to conduct the air supply component 210 and the air supply pipeline 120. The above-mentioned air supply module 222 and the air receiving module 163 are hermetically connected by providing a gasket on at least one of the air supply module 222 and the air receiving module 163. When the positioning plate 223 slides to a set position, the air supply module 222 presses against the air receiving module 163 and squeezes the gasket, thereby achieving sealing.

[0106] In an implementable solution, the air supply component 210 is communicated with the air supply module 222 through a fluid control valve to supply air to the air supply module 222 by the on-off of the fluid control valve. In addition, a throttle speed control valve can also be provided on this air path to adjust the air supply volume.

[0107] The filling unit 10 provided by the embodiment of the present application further includes a conveyor belt. The number of filling assemblies 100 is multiple, and the multiple filling assemblies 100 are fixed on the conveyor belt and move through the conveyor belt. In addition, the number of air supply piles 200 is at least one; when any filling assembly 100 moves through the conveyor belt to a position where it cooperates with one of the air supply units 200, this air supply unit 200 can be used to supply air to this filling assembly 100. Specifically, the filling assembly 100 can be fixed on the conveyor belt through the cartridge bracket 160 and conveyed through the conveyor belt, while the inflation pile 220 is fixed on one side of the conveyor belt. When the filling assembly 100 rotates to a set position, the turnover and discharging device 600 transfers the filling material into the cartridge assembly 110. At the same time, the air supply module 222 on the air supply pile 200 abuts against and conducts with the air receiving module 163 on the cartridge bracket 160, and the air supply component 210 can supply air to the air supply pipeline 120. The filling material can be filled into the filling area of the load-bearing garment. After filling one load-bearing garment, the subsequent filling assemblies 100 are sequentially conveyed through the conveyor belt, and the filling of the load-bearing garment is realized through the cooperation of the turnover and discharging device 600 and the inflation pile 220. It can be seen from this that when the above method is adopted, pipeline-type filling can be realized, and the filling efficiency of the load-bearing garment is improved.

[0108] As can be seen from the above description, the filling unit 10 provided by the embodiments of the present application has a simple structure and is convenient for maintenance. It utilizes compressed air assistance and realizes automatic filling by means of the fluidity of the filling material itself. When multiple cartridge assemblies 110 are adopted, synchronous filling of the left and right sides and the back of the load-bearing garment can be achieved according to the actual formulation process. When the cartridge assemblies 110 are transported by the conveyor belt, the number of inflation piles 220 and filling and filling assemblies 100 can be flexibly configured according to the actual production rhythm to maximize the use efficiency of the equipment. In addition, when the filling unit 10 cooperates with equipment such as an unpacking platform, a weighing device, a conveying device, and a tipping and discharging device 600, the entire filling process can be automatically operated, greatly improving production efficiency, saving production costs, and getting rid of the dependence on operators. In addition, by adjusting the specifications of the hanger 150 and the corresponding air supply pressure and flow rate, filling and filling of different specifications of clothes can be satisfied, and it has a wide adaptability.

[0109] When the filling assembly 100 is transported by the conveyor belt, the transportation of the filling assembly 100 can also be controlled by the control device. Specifically, the filling unit 10 further includes a photoelectric sensor for detecting the filling assembly 100 and a stopper for preventing the conveyor belt from transporting. The control device is further configured to control the stopper to prevent the conveyor belt from continuing to transport the filling assembly 100 when the photoelectric sensor detects that the filling assembly 100 moves to a position where it cooperates with one of the air supply units. When controlled in this way, automatic control of the cooperation between the filling assembly 100 and the air supply unit 200 can be achieved. In addition, the control device can also control the positioning plate 223 to slide to a set position when the filling assembly 100 moves to a position where it cooperates with the air supply unit 200, so that the positioning block 224 in the air supply unit 200 is in positioning cooperation with the positioning hole 1611 in the filling assembly. At the same time, the air supply module 222 is hermetically connected to the air receiving module 163 to conduct the air supply assembly 210 and the air supply pipeline 120.

[0110] In addition to the above control, the control device can also control the cooperation between the tipping and discharging device 600 and the filling assembly. Exemplarily, the control device is further configured to control the tipping and discharging device 600 to fill the filling material into the cartridge assembly in the filling assembly when the photoelectric sensor detects that the filling assembly moves to a position where it cooperates with one of the air supply units. When the filling assembly 100 moves to a position where it cooperates with the air supply unit 200, the filling assembly 100 also moves to a position where it cooperates with the tipping and discharging device 600. Therefore, the control device can control the tipping and discharging device 600 to transfer the filling material into the filling assembly.

[0111] In an implementable solution, the control device is further configured to control the air supply unit to supply air to the cartridge assembly and the inflatable pipeline respectively after the tipping and discharging device 600 fills the cartridge assembly in the filling assembly with the filling material. That is, after the filling material is transferred to the filling assembly 100, the filling of the load-bearing garment can be started. Therefore, the control device controls the air supply unit 200 to supply air to the cartridge assembly 110 and the inflatable pipeline 120 respectively to facilitate the filling of the filling material.

[0112] In a specific control mode, the control device is further configured to gradually reduce the air supply volume of the air supply unit to the inflatable pipeline and gradually increase the air supply volume to the cartridge assembly when controlling the air supply unit to supply air to the cartridge assembly and the inflatable pipeline respectively. When filling the load-bearing garment, since the two layers of fabric of the load-bearing garment are attached in the early stage, a relatively large amount of air needs to be blown in to make the filling area bulge, and the excess air can leak through the gaps in the fabric. At the same time, since there is a relatively large amount of filling material in the previous cartridge 112 and the air pressure is approximately equal to the external air pressure, the required air volume is small. However, as the filling time increases, the filling material in the filling area of the load-bearing garment gradually increases, while the filling material in the cartridge 112 gradually decreases. Therefore, the required air volume in the filling area of the load-bearing garment decreases, while the required air volume in the cartridge increases. To ensure the smooth filling, when controlling the air volume distribution, the air volume entering the cartridge and the filling area is changed according to the filling situation of the filling material. At the same time, as the air volume entering the cartridge increases, a positive pressure can also be provided to increase the filling speed of the filling material. And after the filling is completed, the cartridge can be cleaned with a relatively large amount of air to ensure the accuracy of the filling of the filling material.

[0113] When the entire filling system is in use, first, according to the process formula, the feeder 322 located at the bottom of the corresponding silo 321 will start to work, and deliver the filling material in the corresponding silo 321 to the weighing line. When the delivery amount reaches the set value, the feeder 322 stops feeding. At this time, the container 420 located on the weighing unit 30 will release the weighed filling material to the collecting hopper 510 located on the weighing unit 30. The collecting hopper 510 moves along the conveying line 520 to the turning and unloading device 600 station. After detecting that the filling component is in place, it starts to work. The turning and unloading device 600 clamps the collecting hopper 510 and turns the filling material into the hopper corresponding to the filling component. At this time, the filling material entering the hopper will press the one-way valve to open, and the filling material will then flow into the bottom of the filling component for temporary storage. With the operation of the filling conveyor line 520, when the filling assembly reaches the air filling unit area of ​​the canning unit and is detected by the detection element, the filling assembly is positioned, and the electromagnetic reversing valve on the air filling pile is opened, and the double-axis cylinder extends to drive the air supply module and the positioning block to move downward, and the positioning block cooperates with the positioning hole on the top of the barrel bracket to make the air supply module and the air receiving module align and fit, and then the fluid control valve on the air filling pile is opened, and the compressed air passes through the air supply module, the air receiving module, the blowpipe on the barrel and the filling head in turn along the air pipe, and finally reaches the weight-bearing clothes to expand the weight-bearing clothes to form an internal cavity. Before the airflow enters the blowpipe on the barrel, it will be divided into a path to enter the barrel. At this time, the filling material enters the expanded weight-bearing clothes with its own fluidity until the filler in the barrel is completely filled. Because the weight-bearing garment itself has a certain degree of air permeability, it needs to be continuously supplied with air during the filling stage. The compressed air in the barrel can promote the fluidity of the filler on the one hand, and prevent the backflow of the filler that has entered the weight-bearing garment due to the pressure difference on the other hand. At this point, the filler filling stage is completed.

[0114] To facilitate understanding of the filling system provided in the embodiment of the present application, the embodiment of the present application further provides a method for using the filling system, the filling system being any of the filling systems in the above examples, and the method for using the filling system comprising the following steps:

[0115] Step 001: feeding materials to the weighing unit 30 through the feeding unit 20, and weighing the required filling materials through the weighing unit 30;

[0116] Specifically, when weighing, the weight fed back by the weighing unit 30 is compared with the first set weight. If the weight fed back by the weighing unit 30 is less than the first set weight, the feeding unit 20 is controlled to feed at a high speed; if the weight fed back by the weighing unit 30 is greater than the first set weight, the feeding unit 20 is controlled to feed at a variable frequency. Figures 1 to 9 Related description in .

[0117] Step 002: Convey the weighed filling material to the set position through the hopper carried by the conveying component 500500, and transfer the filling material in the hopper at the set position to the filling unit 10 through the tipping discharging device 600;

[0118] Specifically, detect the position of the filling component through the photoelectric sensor; when the filling component moves to the position where it cooperates with one of the air supply units, control the stopper to prevent the conveyor belt from continuing to convey, and control the tipping discharging device 600 to fill the filling material into the cartridge component in the filling component. For details, please refer to the relevant description above Figures 1 to 9 in it.

[0119] Step 003: Carry the filling material transferred by the tipping discharging device 600 through the cartridge component of the filling component, and fill the filling material in the cartridge component into the load-bearing garment through the filling pipe in the filling head; and inflate the filling area in the load-bearing garment through the inflation pipe in the filling head by the air supply unit, and supply air to the cartridge component.

[0120] Specifically, control the air supply volume of the air supply unit to the inflation pipe to gradually decrease, and the air supply volume to the cartridge component to gradually increase. For details, please refer to the relevant description above Figures 1 to 9 in it.

[0121] In the above technical solution, the feeding unit 20 is adopted for feeding, the weighing unit 30 weighs the required filling material, the conveying unit 40 transfers the weighed filling material to the cartridge component of the filling unit 10, and when the cartridge component inflates the load-bearing garment, the air supply unit synchronously supplies air to the cartridge component and the filling area of the load-bearing garment to facilitate the filling material to be filled into the filling area, thus realizing the automated production of load-bearing garment filling, improving the production efficiency, reducing the labor intensity of workers at the same time. At the same time, compared with manual filling of filling materials, the qualified rate of products is improved.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in this application, and all of them should be covered within the protection scope of this application.
