For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0024] Please refer to Figure 1 and Figure 2 In one embodiment of a down collecting device of the present invention, the down collecting device includes a workbench 1, a first three-way pipe 21, two collecting boxes 3, a second three-way pipe 22, a vacuum pump 4, and a bracket 5;
[0025] The workbench 1 includes a work table 11, a baffle 12 and a lower hopper 13; the table top of the work table 11 is rectangular and is used to place down products. The table top of the work table 11 is provided with hollow holes 111 distributed in a rectangular array. The hollow holes 111 are distributed all over the table top, and the falling down can pass through these hollow holes 111; the baffle 12 is U-shaped, and the baffle 12 is fixedly connected to the edge of the work table 11 and exposed at the front side of the work table 11, which is convenient for workers to stand on the workbench. The operation is performed on the front side of the work table 11, and a circular through hole 121 is opened on one side of the baffle 12. The through hole 121 allows the filling port of the filling machine 8 to pass through and enter the top of the work table 11, so as to facilitate the collection of down; the lower hopper 13 is in an inverted square cone shape, and the upper end of the lower hopper 13 is fixedly connected to the lower surface of the work table 11 and covers all the hollow holes 111. The lower end of the lower hopper 13 is connected to the air inlet pipe of the first three-way pipe 21, and the down falling from the hollow holes 111 passes through the lower hopper 13 and enters the first three-way pipe 21.
[0026] In addition, the two outlet pipes of the first three-way pipe 21 are respectively connected to one end of the two collection boxes 3, and the two outlet pipes are respectively installed with a one-way valve 211 to prevent the air carrying down from flowing back; the two inlet pipes of the second three-way pipe 22 are respectively connected to the other end of the two collection boxes 3, and one outlet pipe of the second three-way pipe 22 is connected to a vacuum pump 4. The vacuum pump 4 can extract the air inside the collection box 3 through the second three-way pipe 22, thereby generating a negative pressure in the collection box 3, which is convenient for collecting the external down; the connection between the three pipes of the second three-way pipe 22 is installed with a three-way solenoid valve 221. The three-way solenoid valve 221 is a device for controlling the flow direction of a fluid (such as a gas or liquid) and is widely used in automated control systems. It has an electromagnetic coil inside. When current passes through it, the coil generates a magnetic field, pushing the valve core to move, thereby changing the flow path of the fluid. The three connecting ports of the three-way solenoid valve 221 of this embodiment are respectively connected to the three pipes of the second three-way pipe 22, and the flow of air can be switched between the two inlet pipes of the second three-way pipe 22 according to the state of the electromagnetic valve.
[0027] In addition, two collection boxes 3 are provided on the bracket 5, and two weighing sensors 6 connected to the above-mentioned three-way solenoid valve 221 are installed in the bracket 5. The two weighing sensors 6 can respectively measure the weight of the two collection boxes 3. The weighing sensor 6 is a device for measuring the weight or force of an object, which is widely used in industries such as industry, commerce, medical treatment and scientific research. It usually converts the applied force or weight into an electrical signal for subsequent processing. Specifically, the bracket 5 includes an upper support plate 51, a lower support plate 52 and four connecting rods 53; two collection boxes 3 are placed on the upper surfaces of the upper support plate 51 and the lower support plate 52, respectively, and two weighing sensors 6 are embedded in the upper surfaces of the upper support plate 51 and the lower support plate 52. When the collection box 3 is placed on the weighing sensor 6, the weighing sensor 6 is subjected to gravity; the four connecting rods 53 connect the four corners of the upper support plate 51 and the lower support plate 52, and the lower ends of the connecting rods 53 pass through the lower support plate 52 to support the upper support plate 51 and the lower support plate 52.
[0028] When this embodiment is in use, the vacuum pump 4 extracts the air from one of the collection boxes 3 through the second three-way pipe 22, so that negative pressure is generated in the collection box 3, so that the air above the workbench 1 carries the newly released down through the hollow hole 111 and enters the collection box 3 through the first three-way pipe 21; Figure 3 Compared with the passive collection method of the existing collection box 9 shown, the vacuum active suction method of this embodiment can collect the down before it floats up.
[0029] In this embodiment, during the down collection process, when the weight of a collection box 3 measured by one load cell 6 reaches a preset value, a controller connected to the load cell 6 and the three-way solenoid valve 221 controls the three-way solenoid valve 221 to switch the air flow to the second three-way pipe 22 corresponding to the other load cell 6. The other collection box 3 then continues to collect down, while the full collection box 3 is processed. The above steps are repeated to achieve uninterrupted down collection. It should be noted that the controller may be a PLC controller, with the output signal of the load cell 6 connected to the input port of the PLC controller, and the output port of the PLC controller connected to the three-way solenoid valve 221.
[0030] Specifically, the two air outlet pipes of the first three-way pipe 21 and the two air inlet pipes of the second three-way pipe 22 can be configured to detachably connect the two collection boxes 3. After the collection boxes 3 are full of down, the collection boxes 3 can be removed to process the down inside and then reinstalled, making them convenient to use. The specific detachable connection method between the first three-way pipe 21 and the second three-way pipe 22 and the collection boxes 3 can adopt the connection method of the pipe joint 7. The pipe joint 7 is a commonly used detachable pipe connection method. It usually consists of two parts: a pipe with an external thread and a joint with an internal thread. By rotating the pipe joint 7, it can be connected to the collection box 3 and the two three-way pipes to form a reliable connection. Of course, other detachable connection methods can also be used, such as a clamp connection.
[0031] Furthermore, a filter screen located inside the air inlet pipe can be provided at the place where the collecting box 3 is connected to the second three-way pipe 22, and the second three-way pipe 22 is connected to the interior of the collecting box 3 through the filter screen. The filter screen can prevent the down in the collecting box 3 from passing through the second three-way pipe 22 and entering the interior of the vacuum pump 4, thereby improving safety.
[0032] Furthermore, an alarm 31 electrically connected to the weighing sensor 6 can be fixedly connected to the outer top wall of the collection box 3. When the weighing sensor 6 measures that the weight value of the collection box 3 reaches a preset value, it sends a signal to the alarm 31 to trigger an alarm, which facilitates timely processing by the staff.
[0033] The usage or working principle of this utility model is as follows:
[0034] A down-filled product is placed on the tabletop of the work table 11, so that the down-filled interface of the down-filled product is connected to the filling port of the down filling machine 8 that passes through the through hole 121. When down floats out from the gap between the filling port and the down-filled interface, the vacuum pump 4 can extract the air inside one of the collection boxes 3 through the second three-way pipe 22, so that negative pressure is generated in the collection box 3, so that the air above the tabletop of the work table 11 carries the down that has just floated out through the hollow hole 111 and enters the collection box 3 through the lower hopper 13 and the first three-way pipe 21.
[0035] When the above-mentioned collection box 3 is full of down, the value measured by the corresponding weighing sensor 6 reaches a preset value, thereby outputting an electrical signal to the controller, and the PLC controller controls the three-way solenoid valve 221 to switch to the air inlet pipe of the second three-way pipe 22 corresponding to another weighing sensor 6, and uses another collection box 3 to continue collecting down. During this period, the collection box 3 that is full of down is processed, and the above steps are repeated to collect down continuously.
[0036] The control logic of the PLC controller is as follows:
[0037] State 1: When the weighing sensor 6A is activated (the collection box 3A is full of down), the three-way solenoid valve 221 switches to the air inlet pipe 2 of the second three-way pipe 22 (air flows to the collection box 3B).
[0038] State 2: When the weighing sensor 6B is activated (the collection box 3B is full of down), the three-way solenoid valve 221 switches to the air inlet pipe 1 of the second three-way pipe 22 (air flows to the collection box 3A).
[0039] State 3: If both the load cells 6A and 6B are inactive, the three-way solenoid valve 221 remains in the initial state.
[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
