As shown in FIGS. 1 and 2, the mass laundry pretreatment apparatus according to the present invention includes a main body housing 100.

At this time, the main body housing 100 is formed in a rectangular box shape having an open interior and an open top, a pair of inlet ports 110 are formed on both sides of the front surface as shown in FIG. 2 (a) As shown in FIG. 2 (b), a pair of outlets 120 are formed on both sides of the rear side.

In addition, a controller 130 for control is installed on a part of the upper surface of the main body housing 100, and the main body housing 100 is disposed on the front end of the large washing machine, so that the laundry can be directly introduced Respectively.

That is, the discharge port 120 is connected to the laundry loading port of the large washing machine.

A water supply pipe 140 is installed on both sides of the main body housing 100 and a water supply valve 142 is provided on the water supply pipe 140 to control the opening and closing of the water supply pipe 140 by the controller 130. At this time, the solenoid valve is an abbreviation of 'solenoid valve', and hereinafter, 'solenoid valve' will be expressed as 'sol valve'.

The first and second dams 150 and 152 are installed inside the main body housing 100 to divide the internal space into three chambers into a left chamber CH1, a center chamber CH2 and a right chamber CH3.

The first and second dams 150 and 152 may be installed at a height of less than a half of the height of the main body housing 100, ) Can be secured.

In addition, since the water supply pipe 140 is connected only to the left chamber CH1 and the right chamber CH2, the two chambers can receive water selectively under the control of the controller 130. [

1 (a). Referring to FIG. 1 (a), when the main housing 100 is projected from above, the ball screw 200 is rotatably mounted on one side of the upper end of the main housing 100, And a drive motor 210 is connected to one end of the ball screw 200. The drive motor 210 is fixed to one side of the main body housing 100, do.

In addition, the open upper surface of the ball screw 200 and the main body housing 100 is covered with the diaphragm 220, which is a plate-like plate, and the material need not be limited. That is, both thin steel plates and plastic plates are possible.

Particularly, the diaphragm 220 is fixed by a fixing pin (not shown) to a plurality of fixing blocks 230 fixed to the upper surface of the main body housing 100 in order to increase the vibration effect do.

In this case, the spot fixing may be performed by fixing one end of the fixing pin to the side surface of the diaphragm 220 by hinging, but it may be fixed by welding.

As described above, the diaphragm 220 has a structure in which the spot is fixed, that is, only the local portion is fixed and the remaining portion is not fixed, so that the entire plate can be easily shaken.

The vibrator 240 is installed on both sides of the top surface of the main body housing 100 and more precisely on both sides of the short side of the main housing 100 so that the vibrator 240 vibrates. ).

At this time, the vibrator 240 can be applied in various forms, but it is particularly preferable to use an ultrasonic vibrator.

A guide bar 250 is fixed to a lower surface of the diaphragm 220. Both ends of the guide bar 250 are fixed by a fixing bracket 252, .

Particularly, the first screw block SB1 and the first bar block BB1 are provided on the ball screw 200 and the guide bar 250, respectively. The first screw block SB1 includes a ball screw And the first bar block BB1 is configured to be slidably engaged with the guide bar 250 while being screwed to the guide bar 200 and moved to the left or right along the rotation direction of the ball screw 200 when the ball screw 200 rotates. .

In addition, the first screw block SB1 and the first bar block BB1 are connected to each other by the first linkage CT1. The first screw block SB1 and the first bar block BB1 are connected to each other through the second screw block SB2, CT2) - second bar block (BB2).

The first cylinder 260 is vertically fixed to the first connecting rod CT1 and the second cylinder 270 is vertically fixed to the second connecting rod CT2. The first fork 264 in the form of a lattice is integrally formed in the cylinder rod 262 and the second fork 274 in the form of a lattice is formed integrally with the second cylinder rod 272 of the second cylinder 270 do.

In this case, the first and second forks 264 and 274 should be sealed electromagnets, the control may be performed by the controller 130, and the wiring may be carried by the first and second cylinder rods 262 and 272.

2 (b), the first fork 264 is positioned in the left chamber CH1 and the second fork 274 is positioned in the center chamber CH2. ≪ / RTI >

The operation of the first and second cylinders 260 and 270 is controlled by the controller 130 in sequence.

On the other hand, the first and second turntables 300 and 310 are installed on the bottom surfaces of the left chamber CH1 and the right chamber CH3 as shown in FIGS. 1C and 3A, The turntables 300 and 310 are configured to be rotatable by a rotary shaft 330 that rotates the shaft 320 and a sealed shaft 320 fixed to the lower center of the turntable 300, And is driven under the control of the controller 130.

Here, the driving sources of the first and second turntables 300 and 310 and the accessories provided on the upper surface are the same, so that only the reference numerals will be described.

That is, four protruding rods 340 are installed on the upper surfaces of the first and second turntables 300 and 310 at 90 degrees in a radial direction. The protruding rods 340 are formed in an antenna- That is, in the form of a telescope.

In other words, the protruding portion protruding from the top surface of the first and second turntables 300 and 310 with a minimum protruding length and being protruded in a multi-stepped fashion is structured to be pulled downward by its own weight when no external force acts, At this time, the minimum protrusion is a base protrusion rod 342, which is firmly fixed to the bottom surface, and a plurality of protruding rods capable of being drawn out in a multi-stage can be provided therein.

Particularly, when the external force is not applied, the weight rod 344 may be provided in the shape of a semicircular cap at the upper end of the uppermost protruding rod so that the protruding rod 340 can be easily lowered and drawn into the base protruding rod 342 by its own weight have.

In addition, since the external force that protrudes the protruding rods 340 is water supplied to each chamber, the protruding height of the protruding rods 340 may vary according to the water level, That is, the water level of the water filled in the left chamber CH1 or the right chamber CH3. That is, the protruding rods 340 are designed to have a height lower than the height of the first and second dams 150 and 152.

A water inlet 350 is formed in the upper surface of the first and second turntables 300 and 310 so that water can flow into each of the protruding rods 340. The water inlet 350 is connected to the water channel 360 And is designed to communicate with the inside of the base protruding rod 342 and the inside of each protruding rod 340.

Therefore, when the left chamber CH1 and the right chamber CH3 are filled with water, a water pressure corresponding to the water level is applied, and water flows to the water inlet 350 by the water pressure and then moves along the water passage 360, The protruding rods 340 are automatically drawn out by the force of pushing up the water.

However, since the water level is maintained much higher than the protruding rods 340, the protruding rods 340 are maintained at the maximum extended state, that is, the protruding state as shown in the drawing, as long as the water is filled.

The reason for protruding the protruding rods 340 is to give a bend by grasping the laundry to be stitched in order to relieve the bark on the surface or the back surface of the laundry,

That is, since the first fork 264 or the second fork 274 is lowered between the protruding rods 340, the laundry to be laid therebetween is separated from the direction in which the first and second forks 264 and 274 are pressed, (340), and the hairpin is easily bent.

In addition, since the first and second turntables 300 and 310 are periodically rotated, the effect of shaking the hair pin is remarkably improved.

Of course, it will be more effective if the step motor is rotated to rotate in a certain direction and then to rotate in the opposite direction. However, considering that the water is filled, the rotation speed should not be fast.

As shown in FIGS. 1 and 3 (b), the center chamber CH2 is provided with a pair of swash plates 400 inclined toward the drain port 410 formed at the center of the width, A pair of sweepers 420 arranged in the width direction are provided on the side fixed to the first and second dams 150 and 152. The sweep fingers 420 are arranged such that a spring 470 Is bound on the flow block (440) by a connecting bar (460).

At this time, the connecting bar 460 is composed of two divided parts, and the two parts separated by the spring 470 are combined to form a single member. Therefore, it is possible to adjust the length by elasticity.

One end of the screw shaft 430 is fixed to the second dam 152 so as to be rotatable about its axis and the screw shaft 430 is fixed to the other end of the swash plate 400 by a screw drive And a screw drive motor 450 is fixed to the first dam 150 and is driven and controlled by the controller 130. [

In addition, the flow block 440 is screwed to the screw shaft 430 and is configured to be movable in either the left or right direction along the rotational direction when the screw shaft 430 rotates.

Therefore, when the second fork 274 is moved, the sweep puddle 420 may be damaged when the laundry, for example, the pillow garment remains on the slope of the swash plate 400 or the hairpin is not discharged to the drain port 410 As it moves, it sweeps it off.

The present invention having such a configuration has the following operational relationship.

First, when a certain amount of laundry is charged into the left and right chambers CH1 and CH2 via the inlet 110, the inlet 110 is closed and the water solenoid valve 142 is opened to supply a predetermined amount of water .

As the water is supplied, the protruding rods 340 on the first and second turntables 300 and 310 are protruded according to the water level. When the protruding rods 340 reach the maximum water level, the protruding rods 340 also protrude to the maximum, .

At this time, since the laundry is floating in the water, the protrusion rod 340 can be easily lifted without applying a large force.

The first and second cylinder rods 262 and 272 are lowered while the first and second forks 264 and 274 are lowered between the protruding rods 340. [ Thereby partially pressing the laundry.

At the same time, electricity is applied to the first and second forks 264 and 274 to be electrostatically charged. As the laundry flows, the first fork 264 instantaneously shakes the laundry, that is, the hairpin attached to the pillowcase, As shown in Fig.

The first and second forks 264 and 274 periodically perform such a lifting operation. When the first and second forks 262 and 274 are lifted up, the first and second turntables 300 and 310 are rotated at a predetermined rotation angle, Shaking, and then descending again.

Therefore, the hairpin or the like is easy to be shaken, and the hairpin or the like that is worn is perfectly adsorbed on the first fork 264.

Here, since the second fork 274 is lifted and lowered in the central chamber CH2, there is no hairpin adsorption effect by the electromagnet. Therefore, it is preferable that the signal is controlled so as not to be electrified unlike the first fork 264.

When the hair removal operation is completed for a predetermined period of time, the first and second forks 264 and 274 are lifted and then moved in accordance with the driving of the driving motor 210.

In this case, the ascending height of the first and second forks 264 and 274 must be higher than the first and second dams 150 and 152 naturally.

Then, the second fork 274 is placed on the right chamber CH3, and the first fork 264 is placed on the center chamber CH2.

This is because the ball screws 200 are rotated in accordance with the rotation of the driving motor 210 and the first and second screw blocks SB1 and SB2 move along with the first and second connecting blocks CT1 and CT2, And the first and second cylinders 260 and 270 move together, the first and second forks 264 and 274 can move naturally.

Thereafter, the first and second forks 264 and 274 are lowered in the center chamber CH2 and the right chamber CH3, respectively, and power is released from the first fork 264, which is lowered in the center chamber CH2, And the second fork 274, which is lowered in the right chamber CH3, is electrified by applying electric power to the second fork 274, The same action as that performed in the left chamber CH1 occurs.

The first and second forks 264 and 274 are alternately moved in the left chamber CH1, the center chamber CH2 and the right chamber CH3 to remove the bone fragments attached to the laundry and adsorb them.

At this time, the vibrator 240 is configured to vibrate under the control of the controller 130, so that the first and second forks 264 and 274 vibrate while descending, thereby further enhancing the bark separation efficiency of a hairpin or the like. In this case, the vibration vibrates the vibrating plate 220 to transmit a strong vibration to the first and second cylinders 260 and 270, and the first and second forks 264 and 274, which are connected to the first and second cylinders 260 and 270, .

Then, the billet and the laundry remaining on the swash plate 400 are swept into the sweepper 420.

Therefore, some of the laundry may come out in some cases, and the laundry may be collected from the drain port 410 and then introduced through the inlet 110 again.

By doing so, it is possible to completely separate and remove the shape of the hairpin or the like attached to the laundry, such as a ship's spine.

In addition, the chambers in which the blanks are separated are loaded with the water into the large washing machine while the discharge port 120 is opened. When the loading is completed, the chamber is washed according to a predetermined sequence in the large washing machine.

In this case, when the pillowcase is discharged, since the water level is high at first, water floating in the water escapes through the discharge port 120, so there is no fear of being caught in the protruding rods, and when the water level is lowered, the protruding rods descend, Since it has this round shape, it does not cause bad discharge. Even if there is a case where the discharge is not made, there is no big problem because it is discharged again in the subsequent process.

In addition, when the input unit 500 as shown in FIG. 4 is further provided on the front end of the main body housing 100, a more complete bone removing operation can be performed.

The input unit 500 illustrated in FIG. 4 includes a pair of branch pipes (not shown) branched in Y-shape so as to be connected to the input chamber 110 formed in the left chamber CH1 and the right chamber CH2 of the main body housing 100 A U-type trap pipe 520 having a single pipe shape connected to the branch pipe 510, a horizontal input pipe 530 connected to the U-trap pipe 520 horizontally, A large blower 540 connected to the end of the horizontal charging pipe 530, a charging conveyor 600 installed in a part of the length of the horizontal charging pipe 530, An opening / closing door 560 installed on the oil trap pipe 520 passing the permanent magnet 550 and a branching valve 560 installed at the branching portion of the branch pipe 510 to determine the direction of introduction of the laundry, Flap 570 as shown in FIG.

In this case, the branching flap 570 provided at the branching portion is not shown, but can be easily realized by configuring the rotation shaft of the branching flap 570 to be rotated by the micro-motor, Can be configured.

The opening / closing door 560 may be of a sliding type simple opening / closing type so as to periodically check the shape of the hairpin containing the hairpin 520 accumulated on the oil pipe 520 and scrape it.

Accordingly, when high-pressure wind is supplied through the large-size blower 540, the laundry, especially pillow-tops, which are put in one by one through the input conveyor 600 is blown by the wind, falls on the superstructure of the oil pipe 520, So that the bending angle of the relatively heavy hairpin is easily separated from the laundry in the process.

The separated hairpin can not proceed due to the permanent magnet 550 but stays on the inner bottom surface of the oil trap tube 520. The remaining laundry is blown by the air pressure to guide the branch flap 570 And is introduced into the main body housing 100 through the inlet 110.

With such a configuration, the bark separation efficiency is more effective, and the laundry can be easily input.

In addition, the input conveyor 600 installed in the input unit 500 may have the same shape as that of FIG.

5, the input conveyor 600 includes a drive pulley 610 driven by a power source, a driven pulley 620 corresponding to the drive pulley 610, and a drive pulley 610 driven by the drive pulley 610 and a driven pulley 620 A pair of belt-shaped belts 630 that are wound on the belt 630 and rotate in the form of an endless track, a cruciform fixing groove 632 formed on the inner surface of each of the belt-type belts 630, A p-type waveguide 640 having a gripping structure 642 that can be rotated within the range of the fixing groove 632 and having an upper end gently protruding to one side, and a driving pulley 610 having a driving pulley 610 and a driven pulley 620 Shaped waveguide 640 interferes with the lower end of the P-type waveguide 640 when the P-type waveguide 640 moves along the belt-shaped belt 630 to change the fixing position of the P- And a bar 650.

According to this configuration, the laundry is sandwiched between the plurality of P-type waveguide 640. At this time, the fitting of the laundry is fixed by the engagement of the P-type waveguide 640. Then, when the P-type wave earth 640 rotates in an endless track form, the laundry can be sequentially moved one by one.

In this case, it is preferable that the workpiece is sandwiched between the P-type waveguides 640 in a state where the worker grasps the laundry, and then the workpieces are inserted one by one. However, when it is necessary to realize the automation of the entire system, It can be improved by a method of sandwiching it by using.

Then, the preceding P-type waveguide 640 is caught by the catching bar 650 installed on the side of the driving pulley 610, and the holding construction 642 is positioned as shown in the upper side in FIG. 5 (a) The bottom of the p-type waveguide 640 is blocked while being caught by the waveguide 650, so that the position of the holding structure 642 is changed as shown in the lower side in Fig. 5 (a).

Then, the leading P-type waveguide 640 is opened with respect to the trailing P-type waveguide 640, and the grasped state of the laundry to be grasped at that moment is released, .

Then, when passing through the driven pulley 620, it is hooked back to the latching bar 650 and returned to its original position.

With such a configuration, the automatic input concept can be introduced while securing the activity of the input source of the laundry, thereby improving the processing efficiency.
