The laundry transportation device is configured to transport the laundry in one direction by being rotated in place with pressing the laundry placed on the conveyor or the supporting plate downward and to spray wash water, rinse water or fabric softener towards the laundry.
Hereinafter, a laundry transportation device with a nozzle according to the preferred embodiments of the present invention will be described in detail with reference to
The laundry transportation device with the nozzle according to the present invention includes a transporting device and a nozzle device as shown in
Herein, the first rotating member 100 is installed to rotate in place by a separately installed power source. The first rotation member 100 may be a gear or a pulley respectively disposed on the left and right sides on the front, and may be a conventional member capable of rotating in place by a power source. In one example, the first rotating member 100 on both sides of the fixing rod 110 may be rotated by a power source, respectively. As another example, the first rotating member 100 on one side may be a driving member that rotates by a power source, the first rotating member 100 on the other side may be installed to be a driven member. Definitely, since the first rotating member 100 on one side and the first rotating member 100 on the other side are connected by the fixing rod 110, it is natural to rotate both of them at the same time.
And also, the fixing rod 110 is a member installed by connecting the compatible first rotating member 100. The fixing rod 110 may be fixed to one or more transporting rollers 120 arranged at a predetermined interval. For example, as shown in
And the transporting roller 120 is mounted on the fixing rod 110 to press the laundry L downward, and is a roller for transferring the laundry L in one direction with rotating in place together with the fixing rod 110. The transporting roller 120 is a form which the inner space 121 is processed in the longitudinal direction. In addition, the transporting roller 120 may be made of a smooth material with a slight elasticity or impact absorption properties including rubber or synthetic resin to facilitate the transfer due to the high grip force with minimize the damage to the surface of the laundry L when the laundry L is pressured downward. Therefore, the supplying pipe 210 of the nozzle device may be installed through the inner space 121 of the transporting roller 120.
And, the transporting roller 120 may be mounted, for example, when three fixing rods 110 are approximately arranged in a triangular shape as shown in
The transporting device configured as described above, when the first rotating member 100 rotates in place, is rotated in place together with the fixing rod 110 and the transporting roller 120, the transporting roller 120 may be configured to press the laundry L downward to transfer in one direction. Here, the laundry L is in the state mounted on the support plate B. At this time, the top surface of the support plate B may be manufactured in a smooth plate shape, for example, the loaded laundry L can be transferred by the rotation of the transporting roller 120, to be fixed. As another example, the support plate B may be a belt of a conveyor rotating in a caterpillar, at this time, the belt may move as the same or similar speed as the rotational speed of the transporting roller 120. The belt may be in the usual flat form or may be in the form of a mesh.
Meanwhile, the nozzle device includes a second rotating member 200, a supplying pipe 210, a valve 220, one or more nozzles 230, and one or more detecting sensors 240.
First, the second rotating member 200 is a member for rotating the supplying pipe 210 within a predetermined range of angles. The second rotating member 200 is disposed on both the left and right sides of the supplying pipe 210 on the front, respectively; and, more particularly, it is positioned so as not to interfere with the first rotating member 100. The second rotating member 200 may be installed to rotate by a separate power source. For example, it may be installed in such a way that the second rotating member 200 on any one side is a driving member that rotates by a power source and the second rotating member 200 in the other side is a driven member. As another example, both of the second rotating member 200 are driving members rotated by the power source, and in any case, only one of the second rotating member 200 may be rotated, and the description thereof will be described hereinafter in detail. The second rotating member 200 is installed to reciprocate in the forward or reverse direction with respect to the direction of travel of the laundry L, and it is to allow the supplying pipe 210 and the nozzle 230 to reciprocate at the same angle as well as the second rotating member 200.
Next, the supplying pipe 210 is a pipe for supplying wash water, rinsing water, or fabric softener to the plurality of nozzles 230. It may be connected to tanks containing wash water, rinsing water or fabric softeners outside the supply pipe 219, and may be installed to supply wash water, rinsing water or fabric softeners supplied from the tanks to the nozzle 230. Here, the supplying pipe 210 may be one installed by connecting the compatible second rotating member 200, or may be two mounted on both sides of the second rotating member 200 toward the center on the front. At this time, when the supplying pipe 210 is two, the second rotating members 200 on both sides are installed to rotate by different power sources, in consideration of the size of the laundry L passing from below or the situation in which the laundry L is moved to one side, it may be controlled to rotate only the second rotating member 200 of any one side. To this end, a plurality of separating plates 250 may be further installed on both sides of the fixing rod 110 on the front side. That is, the end portion of the supplying pipe 210 opposite to the second rotating member 200 and the separating plates 250 may be fastened, and the mounting structure may be rotated in place of the supplying pipe 210 by the second rotating member 200.
Next, the valve 220 is installed to block or flow the wash water, rinsing water or the softener flowing into the supplying pipe 210. The valve 220 may be installed near the compatible second rotating member 200, respectively, or may be installed in the supplying pipe 210, or it may be installed in a separate pipe connecting the supplying pipe 210 and a plurality of tanks containing wash water, rinsing water or fabric softener. The valve 220 is opened and closed by a signal from the detecting sensor 240, and can operate to open one or both of each supplying pipe 210. Of course, the valve 220 may adjust the flow rate as well as opening and closing of the wash water, rinsing water or the fabric softener. The valve 220 may be a conventional valve including a solenoid valve to open and close wash water, rinsing water, or fabric softener.
Next, the nozzle 230 is mounted to the supplying pipe 210 to spray the wash water, rinsing water or fabric softener to the laundry L. The nozzle 230 may be installed at a predetermined interval in plural at the longitudinal direction of the supplying piper 210. At this time, the nozzle 230 may rotate together with the supplying pipe 210 that rotates within a predetermined range of angle by the second rotating member 200. For this reason, the wash water, rinsing water, or fabric softener sprayed to the laundry L through the nozzle 230 may be sprayed within a range or angles. The description thereof will be described hereinafter in detail.
Finally, a plurality of detecting sensors 240 are installed to detect the laundry L entering and passing through the nozzle 230. The detecting sensor 240 may be installed to detect the laundry L prior to the injection of the wash water, rinsing water or the fabric softener or the nozzle 230. The detecting sensor 240 mounted on the support plate B detects the entering laundry L and the size thereof, and supplies the signal to spray the wash water, rinsing water or fabric softener from the nozzle 230 according to the area of laundry L and to stop the wash water, rinsing water or fabric softener sprayed from the nozzle 230 when the laundry L passes. In addition, the signal of the detecting sensor 240 may be open and close the valve 220 to control the flow of wash water, rinsing water or fabric softener, and may control the operation of the power source for rotating the second rotating member 200.
In addition, the signal of the detecting sensor 240 may control the in-situ rotation of the transporting roller 120 by controlling the operation of the power source for rotating the first rotating member 100. For example, the signal of the detecting sensor 240 may be directly transmitted to the valve 220, the power source of the second rotating member 200, and the power source of the first rotating member 100. As another example, a signal of the detecting sensor 240 may be transmitted to a controller installed separately, and then the controller may generate a control signal for controlling the power source of the valve 220 and the second rotating member 200.
First, the detecting sensor 240 detects the laundry L entering with being placed on the supporting plate B S10. At this time, the plurality of detecting sensors 240 installed on both sides on the front side detect the laundry L; and, when the plurality of detecting sensors 240 detect the laundry L, wash water, rinsing water or fabric softener may be supplied to the supplying piper 210 by opening both sides of the valve 220. In addition, when only some of the detecting sensors 240 detects the laundry L, the wash water, rinsing water or fabric softener can be supplied only to one side supplying pipe 210 by opening only one side of the valve 220 in which the laundry L is detected.
Next, when the detecting sensor 240 detects the laundry L, the nozzle 230 sprays the wash water, the rinsing water or the fabric softener while the nozzle 230 reciprocates in an angle of range of 5 to 45 degrees in the traveling direction of the laundry L S20. That is, when the detecting sensor 240 detects the laundry L entering the nozzle 230, the nozzle 230 can spray the wash water, the rinsing water or the fabric softener while it has an angle range of 5 to 45 degrees in the traveling direction of the laundry L on the side with respect to the downward vertical line. This is to allow the laundry L to enter smoothly without falling from the supporting plate B.
Next, while the laundry L passes, the nozzle 230 sprays the wash water, the rinsing water or the fabric softener with reciprocating in the angular range of 45 degrees on the left and right sides with reference to the downward vertical line S30. This allows efficient washing or rinsing and can proceed with the laundry fixed.
Next, when the detecting sensor 240 recognizes the rear end of the laundry L, the nozzle 230 sprays the washing water, the rinsing water or the fabric softener while reciprocating in the angle range of 5 to 45 degrees in the reverse direction to the traveling direction of the laundry L on the side with respect to the vertical line S40. This is to allow the laundry L to proceed to the next step in the unfolded state as much as possible without disturbing the progress of the laundry L passing therethrough. Of course, the laundry L can be maintained in an unfolded state by the plurality of transporting rollers 120.
Finally, if the detecting sensor 240 detects the next laundry L, the process returns to the step S20, and if not detected, the operation is stopped.
As described above, washing and rinsing are carried out by maintaining the state in which the laundry L is unfolded by the plurality of transporting rollers 120 and the fixing rods 110 as it is, in this case, how the laundry is actually fixed will be described with reference to
As
