Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a blind cleaning method that automatically cleans so-called Venetian blinds, etc., which have a large number of horizontally extending blades arranged vertically and spaced apart. It is related to the device.

[Conventional technology and problems]

Generally, so-called Venetian blinds are widely used, which are constructed by stacking a large number of horizontally extending blades vertically at intervals. Such blinds tend to have dust, cigarette tar, etc. attached to the blade surface.
They get dirty easily, but because each blade is not fixedly arranged to accommodate changes in the angle of sunlight and is flexible, it has a structure that is extremely difficult to clean.

Therefore, in the past, blinds had to be cleaned manually by wearing gloves, applying detergent or the like to the gloves, and wiping both sides of each blade with the gloves. Therefore, the cleaning operation is extremely inefficient and even damage to the blade may occur during cleaning.

Therefore, in order to automatically clean the blinds without manual operation, a blind cleaning device configured as shown in FIGS. 4 and 5, for example, is provided.
Proposed by the applicant.

In FIG. 4, the blind cleaning device 1 includes a blind supporting device 2 and a blind cleaning section 3. As shown in FIG. The blind support device 2 supports the blind B in a suspended state with its support arm 2a, and causes the support arm 2a to reciprocate in the vertical direction between a solid line position and a chain double-dashed line position using a drive device 2b. , the blind B is moved up and down at an appropriate period. In addition, the blind cleaning section 3 is
A cleaning tank 4 capable of accommodating the blind B when the support arm 2a of the blind support device 2 is at the two-dot chain line position, that is, at the lowered position of the blind B.
have.

Near the upper end of the cleaning tank 4, cleaning brushes 5 and 6 are disposed facing each other along the longitudinal direction so as to sandwich the blind B from both sides, and these cleaning brushes 5 and 6 are not shown. The cleaning brushes 5, 6 are horizontally reciprocated in opposite directions along the longitudinal direction as indicated by arrows P and Q by a known driving means, and are moved along the upper sides of the cleaning brushes 5, 6 onto the cleaning brushes 5, 6. Pipes 7 and 8 having nozzles for spraying water or the like are arranged parallel to each other.

According to the blind cleaning device 1 configured as described above, cleaning of the blind B is performed as follows. That is, first, the cleaning tank 4 is filled with a cleaning liquid (detergent liquid or simply fresh water, etc.), and the blind B is mounted on the support arm 2a of the blind support device 2.
Attach to. At this time, the blind B is in the position shown by the solid line in FIG.

Next, the support arm 2a of the blind support device 2
is reciprocated in the vertical direction by the drive device 2b,
As a result, the blind B is lowered and the cleaning tank 4
into the cleaning liquid inside and then rise up. At this time, the cleaning brushes 5 and 6 are horizontally reciprocated along the longitudinal direction of the blind B in opposite directions, that is, in the directions of arrows P and Q in FIG. 5, while sandwiching the reciprocating blind B from both sides. Then, the blind B is cleaned by brushing the surface of each blade of the blind B. Since the blade surface is already immersed in the cleaning liquid in the cleaning tank 4, this brushing removes dust and the like attached to the surface.

Thereafter, depending on the degree of contamination of the cleaning liquid, the cleaning liquid in the cleaning tank 4 is discharged from the cleaning tank 4,
The blind B is rinsed by introducing fresh water into the cleaning tank 4 through the nozzles 7 and 8.

However, in the blind cleaning device configured in this way, the support arm 2a of the blind support device 2 moves up and down while supporting the entire blind B in a suspended state, thereby lowering the blind into the cleaning tank 4. Because the blind support device is designed to rise from the cleaning tank, the height of the blind support device becomes very high.
Installation space for the blind cleaning device 1 is also required above. In particular, since it is tall when it is loaded onto the bed of a truck and moved, it is necessary to transport it with the blind support device 2 removed and reassemble the blind support device before use. Installation work was not easy and work efficiency was poor.

[Purpose of invention]

Therefore, an object of the present invention is to have a relatively low overall structure, so that the installation space is relatively small and it can be easily transported when moving.
An object of the present invention is to provide a blind cleaning device that can automatically clean blinds.

[Means and actions for solving problems]

According to the present invention, the present invention comprises a blind support device for supporting the blind in an expanded state and reciprocating the blind in the vertical direction relative to a cleaning tank, and a cleaning section for the blind, the cleaning section for the blind comprising: a cleaning tank accommodating the blind in the lowered position of the blind and capable of being filled with cleaning liquid;
cleaning brushes disposed opposite to each other along the longitudinal direction in the cleaning tank so as to sandwich the blind from both sides and horizontally reciprocated in opposite directions along the longitudinal direction; As the blind moves up and down in the cleaning tank,
In a blind cleaning device that uses a cleaning brush to brush the blade surface of a blind immersed in a cleaning solution, the blind support device is arranged on one side of the cleaning tank and is connected to a parallel rotating shaft extending in the longitudinal direction. The belt conveyor is wound around the belt surface and has a hook part for locking the blind to the surface of the belt.By rotating the belt conveyor around a rotating shaft, the blind can be fixed at least in the area above the cleaning tank. This is achieved by reciprocating in the vertical direction.

According to this invention, the cleaning of the blind can be automatically and easily and reliably performed, and the blind supporting device that moves the blind up and down to insert and remove the blind into the cleaning tank can be used to hold the blind in the unfolded state on a belt conveyor. The blind is supported by wrapping it around the belt, and by rotating the belt conveyor in this state, the blind is reciprocated in the vertical direction on one side of the belt conveyor, so the overall height of the blind support device is relatively small. This means that it can be configured with a low target.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on the embodiments shown in the drawings.

1 and 2 show an embodiment of a blind cleaning device according to the present invention, and the blind cleaning device 10 includes a blind support device 11 and a blind cleaning section 12.

The blind support device 11 is provided with a belt conveyor 113 that is wound around parallel rotating shafts 111 and 112 (four rotating shafts in the illustrated case) that are disposed on one side of a cleaning tank, which will be described later, and extend in the longitudinal direction. A hook portion 114 for locking the head box of the blind is provided on the surface of the belt. This hook portion 114
As shown in FIG. 2, this includes a locking plate 117 that is pressed by the action of a compression spring 116 against a plate-shaped substrate 115 that protrudes radially from the surface of the belt conveyor 113. The head box H of the blind B is clamped and fixedly held between the locking plate 117 and the locking plate 117.

In this way, the blind support device 11 is able to support the head box H of the blind B with its hook portion 114.
By locking, the blind B is wound around and supported along the surface of the belt conveyor 113 in the unfolded state, and by rotating one of the rotating drums 111, 112 by the drive device 118. In a region on one side of the belt conveyor 113, the blind B is moved vertically back and forth between the solid line position and the two-dot chain line position, thereby vertically moving the blind B at an appropriate period.

Note that the drive device 118 is configured to transmit rotational torque from a motor capable of forward and reverse rotation to the rotating drum 111 or 112 via a transmission mechanism such as a belt, gear, or chain, but only in one direction. It goes without saying that the rotational torque from the motor that rotates may be switched by gears.

Furthermore, without using the drive device 118 as a rotational drive means for the belt conveyor 113,
For example, by attaching a grip portion to one rotating shaft 111, it is of course possible to rotate the rotating shaft manually.

The blind cleaning unit 12 cleans the blind B at the lowered position, similar to the conventional example shown in FIG.
It has a cleaning tank 13 that can accommodate. Near the upper end of the cleaning tank 13, cleaning brushes 14 and 15 are disposed facing each other along the longitudinal direction so as to sandwich the blind B from both sides, and these cleaning brushes 14 and 15 are not shown. It is horizontally reciprocated in mutually opposite directions along the longitudinal direction by a known driving means, and has nozzles along the upper sides of the cleaning brushes 14 and 15 for spraying cleaning water and the like onto the cleaning brushes 14 and 15. The tubes 16, 17 are arranged parallel to each other.

The embodiment of the blind cleaning device according to the present invention is constructed as described above, and according to this blind cleaning device 10, the cleaning of the blind B is performed as follows.

First, the cleaning tank 13 is filled with cleaning liquid, and the head box H of the blind B is fixedly held on the hook part 114 of the belt conveyor 113.
By wrapping the blind B along the outer surface of the belt conveyor 113, the blind B is supported by the blind support device 11.
At this time, the blind B is in the position shown by the solid line in FIG.

Next, the belt conveyor 113 of the blind support device 11 is rotated in the direction of arrow X by the drive device 118, so that the blind B is reciprocated in the vertical direction in an area on one side of the belt conveyor 113, As a result, the blind B descends and enters the cleaning liquid in the cleaning tank 13, and then the belt conveyor 113 is rotated in the opposite direction to the arrow X, so that the blind B is raised, and this vertical movement is constant. Repeated in cycles.

At this time, the cleaning brushes 14 and 15 are horizontally reciprocated in mutually opposite directions along the longitudinal direction while sandwiching the vertically reciprocating blind B from both sides, thereby brushing the surface of each blade of the blind B. By doing this, the blind B is cleaned. Since the blade surface of this blind B has already been immersed in the cleaning liquid in the cleaning tank 13, dust and the like adhering to the blade surface are removed by this brushing.

Thereafter, if necessary, the cleaning liquid in the cleaning tank 13 is discharged from the cleaning tank 13, and fresh water is introduced into the cleaning tank 13 through the nozzles 16 and 17, thereby rinsing the blind B.

If the belt surface of the belt conveyor 113 is formed in a grid or net shape, the blind B can be rolled up and drained at the same time after washing, and if a dryer or the like is installed adjacent to the belt conveyor 113, The blind B can be quickly dried after washing.

[Effect of idea]

As described above, according to the blind cleaning device of the present invention, the blind support device that supports the blind in an expanded state and makes reciprocating movement in the vertical direction with respect to the cleaning tank is disposed on one side of the cleaning tank. It consists of a belt conveyor that is wound around a parallel rotating shaft extending in the longitudinal direction and has a hook part for locking a blind, for example, a head box, on the belt surface, and the belt conveyor is rotated around the rotating shaft. Since the blind is configured to be reciprocated in the vertical direction at least in the area above the cleaning tank, cleaning of the blind can be easily and reliably performed automatically, and the blind can be inserted into and removed from the cleaning tank. A blind supporting device for vertically moving the blind supports the blind by wrapping the blind in an expanded state around a belt conveyor, and rotates the belt conveyor to move the blind on one side of the belt conveyor. Since the blind supporting device is reciprocated in the vertical direction, the overall height of the blind supporting device can be made relatively low.

Furthermore, since the entire outer surface of the belt conveyor supports the blind, the belt conveyor itself may have a relatively low strength and may be made of plastic, for example.

Thus, according to the present invention, it is possible to provide an extremely excellent blind cleaning device that requires a relatively small installation space and can be easily transported due to its relatively low overall height. .
