Description

Apparatus for discharging down-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a down discharge apparatus, and more particularly, to a down discharge apparatus which discharges a predetermined amount of down from a down storage tank.

Ducks, which are ducks and goose hair, are excellent in warmth and light weight, and are widely used in clothing and bedding. Down is a mixture of ducks, goose's neck, chest hair and feathers. Generally, the ratio of hairs to feathers included in the down is 4: 1 to 9: 1. The higher the ratio of the hairs, the lighter and warmer the hairs are used.

Down products such as clothes and bedclothes that are used down have a structure in which down-charged parts are charged down. Down is not unlike cotton, and each one is independent, so if you use the down product for a long time, the down will be stuck to one side.

In order to solve such a problem, the down-product is divided into a plurality of parts by sewing, in which the down-charged parts can be charged down. Down charge of the down product is blown into the down charge section by a predetermined pressure using a down injection tool connected to the down storage tank.

When the down is injected as described above, a problem may occur that the down-charged portion is not charged with a certain amount of down. As a result, the amount of the down charge to be charged in the down-charged portion is not constant, which may result in a problem that the uniformity of the down product is inferior. In some cases, there is a problem that the necessary down-time is charged in the down-charged portion and the down-state is wasted.

Korean Patent No. 10-0919967 (September 25, 2009)

In order to solve this problem, it is possible to consider a method in which the weight of the down which the operator drains from the down storage tank is metered by the weighing scale, and then the down-loaded portion is charged by the metered amount. In this case, since the worker has to quantify the amount of the down-load, the work speed for manufacturing the down-product may be significantly lowered.

The user (worker) has to weigh the down by using the balance. However, the down may deviate from the process of weighing the down or moving the weighed down to the down charge unit. This is because it is not easy to handle the down in the open space.

Accordingly, it is an object of the present invention to provide a down discharge device capable of discharging a certain amount of down from a down storage tank.

Another object of the present invention is to provide a down discharge device capable of solving the problem that the operation speed for manufacturing a down product is lowered according to the down measurement.

In the down discharge apparatus according to the present invention, the down discharge valve includes a second air supply and a second shutter. The second air supplier is installed in the down drain pipe and provides the down drain pipe with air for moving down from the tank body to the down drain pipe. The second shutter is installed in the down drain pipe close to the second air supply unit and opens and closes the down drain pipe.

In the down discharge apparatus according to the present invention, the down discharge section includes a porous tube, a sac tube, and an air output tube. The perforated pipe is formed in the down drain pipe far from a position where the down discharge valve is installed in a direction in which down discharge is performed, and a plurality of air discharge holes are formed. The sac tube is surrounded by the perforated tube. The air outlet tube is connected to the sac plate, and discharges air discharged to the sac plate through the air discharging hole to the outside of the sac plate. At this time, the down drain pipe is protruded out of the sac catheter.

First Embodiment

1 is a block diagram showing a configuration of a down discharge device according to a first embodiment of the present invention.

Referring to FIG. 1, the down discharge apparatus 100 according to the first embodiment measures an amount of down discharged from the down storage tank 30 and discharges the discharged down discharge by a predetermined amount. The down discharge apparatus 100 includes an input unit 10, A down weight measuring unit 60, a down discharging unit 70, and a control unit 90. In addition, the down discharge apparatus 100 according to the first embodiment may further include a storage unit 20.

The input unit 10 provides a plurality of keys for operating the down discharge device 100, and generates a selection signal according to the user's selection of the key to transmit the generated selection signal to the control unit 90. The user can set the discharge amount of the down through the input unit 10 and instruct the discharge of the down. The input unit 10 may be an input device such as a pointing device such as a button, a keypad, a touch pad, or a touch screen.

The storage unit 20 stores a program necessary for controlling the operation of the down discharge device 100 and information generated during the execution of the program. The storage unit 20 stores a program necessary for setting a discharge amount of the down and an execution program for discharging the down discharge to the set discharge amount. The storage unit 20 stores information on the set down amount of the down. The set down amount of the down may be provided in a default form or may be set according to the user's setting through the input unit 10. [

The down storage tank 30 stores down. Down storage tank 30 can be supplied with the down through the down supply pipe 33 formed at the upper part and down can be discharged to the outside through the down discharge pipe 43 formed at the lower part. The down supply pipe 33 is provided with a down supply valve 35 for opening and closing the down supply and the down discharge pipe 43 is provided with a down discharge valve 45 for opening and closing the down discharge. As will be described later, the down feed valve 35 and the down drain valve 45 feed down in an air transfer manner.

The down weight measuring unit 60 measures the weight of the down stored in the down storage tank 30. The down weight measuring unit 60 measures the amount of down-down in the down-storing tank 30 when the down-weight discharging unit 60 discharges the down-weight to the control unit 90. At this time, a load cell may be used as the down weight measuring unit 60.

The down discharge unit 70 discharges the down from the down storage tank 30 to the outside. The down drainage unit 70 discharges the downward amount of the downward drainage tank 30 in a predetermined amount, which is set to the outside, in cooperation with the down drainage valve 45 under the control of the control unit 90.

The control unit 90 is a microprocessor that performs the overall control operation of the down discharge device 100. The control unit 90 can set the amount of down to be discharged according to the selection signal through the input unit 10. [ The control unit 90 controls the down storage tank 30, the down weight measuring unit 60, and the down discharge unit 70 such that the set down amount is discharged from the down storage tank 30.

That is, the control unit 90 discharges the down through the down discharge unit 70 to the down storage tank 30 when the down discharge signal is inputted through the input unit 10. The control unit 90 measures the amount of change of the down state in the down-storing tank 30 through the down-weight measuring unit 60. When the set amount is discharged, the control unit 90 blocks the discharge of the down through the down discharge unit 70.

Downstream storage tank 30, down weight measurement unit 60, down discharge unit 70, and down discharge pipe 70, except for the end of down supply pipe 33 and the end of down discharge pipe 43 protruding out of down discharge unit 70, The storage unit 20 and the control unit 90 may be embodied in a case 80. The input unit 10 may be disposed on the outer surface of the case 80.

The down discharge device 100 according to the first embodiment will be described in more detail with reference to FIGS. 1 and 2. FIG. 2 is a view showing the down discharge apparatus 100 of FIG.

Down storage tank 30 includes tank body 31, down feed pipe 33, down feed valve 35, down drain pipe 43 and down drain valve 45.

The tank body 31 has a storage space for storing the down. An air discharging portion 57 is formed at the upper end of the tank body 31 to discharge air. At this time, the air discharging part 57 may be formed directly on the upper end of the tank body 31 through a plurality of holes passing through the tank body 31. Or the air discharging part 57 is formed in the form of a lid covering the upper end of the tank body 31 with the upper end opened, and a plurality of holes may be formed in the lid. At this time, the hole formed in the air discharge part 57 may be formed to have a size capable of selectively discharging air except for downward from the inside of the tank body 31.

The down feed pipe 33 is formed on the top of the tank body 31 and provides a passage for supplying the down into the tank body 31.

The down feed valve 35 is provided in the down feed pipe 33 and opens and closes the supply of the down into the tank body 31 under the control of the control unit 90. The down supply valve 35 includes a first air supply 37 and a first shutter 39. [ The first air supplier 37 is installed in the down-feed pipe 33 and provides air to the down-feed pipe 33 for moving the down from the down-feed pipe 33 into the tank body 31. The first shutter 39 is installed in the down-feed pipe 33 close to the first feeder, and opens and closes the down-feed pipe 33.

The down drain pipe 43 is formed at the bottom of the tank body 31 and provides a passage for discharging down to the outside of the tank body 31.

The down discharge valve 45 is provided in the down discharge pipe 43 and opens and closes the discharge of the downward out of the tank body 31 under the control of the control unit 90. The down discharge valve 45 includes a second air supply 47 and a second shutter 49. The second air supplier 47 is installed in the down discharge pipe 43 and provides air to the down discharge pipe 43 for moving the down from the tank body 31 to the down discharge pipe 43. The second shutter 49 is installed in the down discharge pipe 43 close to the second air supply 47 and opens and closes the down discharge pipe 43.

At this time, the down discharge valve 45 is installed in the down discharge pipe 43 close to the tank body 31 rather than the down discharge port 70.

The controller 90 opens and closes only the down supply valve 35 and closes the down discharge valve 45 when the tank body 31 is down. The control unit 90 opens and closes only the down discharge valve 45 and closes the down supply valve 35 when discharging down the tank body 31.

The down discharge unit 70 includes a porous tube 71, a sac tube 75 and an air discharge tube 77, and may further include a third air supplier 78. The perforated pipe 71 is formed in the down drain pipe 43 distant from the position where the down drain valve 45 is installed in the down drain direction and a plurality of air drain holes 73 are formed. The sac cask 75 surrounds the perforated pipe 71. The air outlet tube 77 is connected to the sac shell 75 and discharges air discharged to the sac shell 75 through the air discharge hole 73 out of the sac shell 75.

At this time, the down drain pipe 43 is protruded out of the sac cask 75 at an outlet portion through which down is discharged.

The porous pipe (71) may be formed to have the same inner diameter as the down discharge pipe (43). For example, the porous pipe 71 can be implemented by forming a plurality of air vent holes 73 directly in the down-stream pipe 43. It is preferable that the air vent hole 73 is formed in such a size that only the air other than the down air can escape.

The down discharge unit 70 discharges the air discharged down with the down discharge pipe 43 to the outside through the air discharge pipe 77 because the air is supplied to the down charge unit through the down discharge pipe 43 In order to restrain it. When more air than necessary is injected into the down-charged section together with the down-flow, the down-flow injected into the down-charged section may cause the problem of coming out of the down-charged section by the injected air.

The down discharge unit 70 may further include a third air supply unit 78 so that air can be discharged to the outside through the air discharge pipe 77 more smoothly. The third air supply 78 is connected to the air output tube 77 and injects air into the air output tube 77 to form a flow of air from the sac tube 75 toward the air output tube 77.

At this time, the control unit 90 controls the down discharge valve 45 and the third air supplier 78 to communicate with each other when controlling the discharge of the down. That is, the control unit 90 opens the down discharge valve 45 and injects air into the air discharge pipe 77 through the third air supply unit 78 when discharging down. The control unit 90 cuts off the down discharge valve 45 to shut off the air injection to the air discharge pipe 77 through the third air supply unit 78 when the discharge of the down discharge is blocked.

As described above, the down discharge apparatus 100 according to the first embodiment can measure the amount of down discharged from the down storage tank 30 and discharge it by a predetermined amount. That is, the down weight can be discharged by a predetermined amount based on the amount of down stored in the down storage tank 30 through the down weight measuring unit 60 provided in the down storage tank 30.

The down discharge apparatus 100 according to the first embodiment is capable of injecting a down amount of metered quantity directly to the down charge section through the down discharge pipe 43, It is possible to minimize the problem of the downward deviation from the outside.

Since the down discharge apparatus 100 according to the first embodiment collectively performs the down weighing and injection, it is possible to improve the work speed for manufacturing the down product and to improve the productivity.

Second Embodiment

3 is a view showing a down discharge device 200 according to a second embodiment of the present invention.

3, the down discharge apparatus 200 according to the second embodiment includes an input unit 10, a storage unit 20, and a down storage tank 30, similar to the down discharge apparatus 100 according to the first embodiment. A down weight measuring unit 60, a down discharge unit 170, and a control unit 90. The down discharge device 200 according to the second embodiment further includes a lattice plate 51, a first air gun 53 and a second air gun 55. The down discharge device 200 according to the second embodiment has a configuration in which the configuration of the down discharge part 170 is different from that of the down discharge part according to the first embodiment.

Therefore, in the description of the down discharge device 200 according to the second embodiment, description of the same components as those of the first embodiment will be omitted, and new or changed components will be mainly described.

The down storage tank 30 includes a tank body 31, a down feed pipe 33, a down feed valve 35, a down discharge pipe 43 and a down discharge valve 45 and includes at least one grid plate 51, And further includes a first air gun 53 and a second air gun 55.

At least one of the grid plates 51, first air gun 53 and second air gun 55 suppresses or eliminates the downward convergence of down into down storage tanks 30, .

At least one grid plate 51 is provided inside the tank body 31 above the down discharge pipe 43 to prevent the downflow of the tank body 31 from falling down below the tank body 31. That is, when the size of the tank body 31 is not less than the proper size, there is a possibility that the down-weight is pushed down toward the bottom of the tank body 31 due to the weight of the down body. In order to solve such a problem, it is possible to solve the problem that the downward movement of the downward movement is directed toward the bottom of the tank body 31 by providing the grid plate 51 inside the tank body 31.

Of course, when the size of the grid formed on the grid 51 is too small, the down-grid can not be moved by the grid 51 and may accumulate on the grid 51. Therefore, in consideration of such a problem, it is preferable that the size of the lattice formed on the lattice plate 51 is formed to have a size enough to pass down. The size of the lattice is preferably adjusted according to the capacity and height of the tank body 31.

At least one first air gun 53 is installed on the tank body 31 adjacent to at least one grid plate 51 and supplies air to at least one grid plate 51 under the control of the controller 90, (51). That is, even if the lattice formed on the lattice plate 51 is formed to have a size enough to allow the downward to pass through, a problem may occur that the lattice is accumulated on the lattice. Therefore, by blowing air to the grid plate 51 by using the first air gun 53, the downward movement of the grid plate 51 can be suppressed while preventing the downward accumulation on the grid plate 51 unnecessarily.

At least one second air gun 55 is installed in the tank body 31 on which the downward discharge pipe 43 is formed and the downward flow of the downward discharge pipe 43 is controlled by the controller 90, &Lt; / RTI > That is, in the process of discharging down to the down drain pipe 43, the down drain pipe 43 is connected to the inlet of the down drain pipe 43 connected to the tank body 31. If the down-flow is too much, the down-drain pipe 43 may not be smoothly discharged. Therefore, by using the second air gun 55 to blow air into the tank body 31 at the inlet of the down-drain pipe 43, the down-flow to the inlet of the down-drain pipe 43 is dispersed inside the tank body 31 . Therefore, downflow can be smoothly discharged through the down drain pipe (43).

On the other hand, the down discharge device 200 according to the second embodiment has disclosed an example including both the lattice plate 51, the first air gun 53 and the second air gun 55, but the present invention is not limited thereto. That is, at least one of the lattice plate 51, the first air gun 53, and the second air gun 55 may be provided in the down discharge device 200.

The down discharge portion 170 includes a porous tube 71, a sac tube 75, an air discharge tube 77, and a third air supply 78. At this time, the porous pipe (71) is formed between the down drain pipes (43) and formed to have an inner diameter larger than the inner diameter of the down drain pipe (43). By forming the inner diameter of the porous pipe 71 larger than the inner diameter of the down drain pipe 43, it is possible to lower the down flow rate discharged to the outlet of the down drain pipe 43, There is an advantage that it can be performed smoothly.

The partition wall 76 can be formed inside the sac plate 75 so as to stably support the sac plate 75 while maintaining a more stable airtightness between the porous plate 71 and the sac plate 75. [ The partition wall 76 may include a first partition wall 76a formed at the start point of the pore tube 71 and a second partition wall 76b formed at the end point of the pore tube 71. [

As described above, the down discharge apparatus 200 according to the second embodiment can measure the amount of down discharge discharged from the down storage tank 30 in the same manner as the discharge discharge apparatus 100 according to the first embodiment, have. That is, the down weight can be discharged by a predetermined amount based on the amount of down stored in the down storage tank 30 through the down weight measuring unit 60 provided in the down storage tank 30.

Third Embodiment

4 is a view showing a down discharge portion 270 of the down discharge device according to the third embodiment of the present invention.

4, the down discharge apparatus according to the third embodiment has the same structure as the discharge apparatus 100, 200 according to the first or second embodiment except for the down discharge unit 270 have.

The down discharge portion 270 of the down discharge device according to the third embodiment includes a perforated pipe 71, a sacrificial pipe 75, an air discharge pipe 77, and a third air supply 78. At this time, the porous pipe (71) is formed between the down drain pipes (43) and formed to have an inner diameter larger than the inner diameter of the down drain pipe (43).

The down discharge unit 270 is opened in front of the sac packing pipe 75 in such a direction that the down discharge is performed so that the outside air can be sucked. Therefore, if the air is supplied to the air output pipe 77 through the third air supplier 78 when the down is discharged through the down discharge pipe 43, air is supplied through the open portion 79a of the sac packing 75, The air discharged from the porous pipe 71 to the jet pipe 75 can be smoothly discharged to the outside through the air output pipe 77 because the air is supplied to the air output pipe 77 through the cat pipe 75.

The partition wall 76 can be formed inside the sac plate 75 so as to stably support the sac plate 75 between the porous plate 71 and the sac plate 75. [ The partition wall 76 may be formed at the starting point of the porous tube 71.

A filter 79 may be installed in the opening 79a to prevent foreign substances from being sucked in the process of sucking air through the open portion 79a of the sac shell 75. [

The down discharge apparatus according to the third embodiment can measure the amount of down discharge from the down storage tank 30 and discharge it in a fixed amount as in the case of the down discharge apparatus 100 according to the first embodiment . That is, the down weight can be discharged by a predetermined amount based on the amount of down stored in the down storage tank 30 through the down weight measuring unit 60 provided in the down storage tank 30.

It should be noted that the embodiments disclosed in the present specification and drawings are only illustrative of specific examples for the purpose of understanding, and are not intended to limit the scope of the present invention.
