Description

[Detailed Description of the Invention] The present invention relates to a surface cleaning machine for cleaning the surfaces of bedding such as pine mattresses, mattresses, comforters, etc.

Hitherto, as disclosed in Japanese Unexamined Patent Publication No. 57-125797, there has been known a method of regenerating a futon without having to rehash it, and a futon surface washer is used to carry out the method. By the way, this surface cleaning machine is equipped with a chamber containing a pair of rotating cleaning brushes on a single belt conveyor, and separate water sprays or detergent sprays are installed near each brush, and water and detergent sprays are disposed from these sprays. Brushing is performed by spraying detergent at high pressure onto the contact area between the rotating cleaning brush and the futon on the conveyor.

However, with this configuration, only one side of the futon can be washed, and when washing the other side of the futon next, it is necessary to transport and turn the futon (turning it inside out), which is difficult to do if the futon was washed in the previous wash. It was hard work because it had absorbed water and had become heavy.

Therefore, an object of the present invention is to provide a bedding surface cleaning machine that is easy to use and can clean either one or both sides of bedding such as a futon with simple operations.

That is, the present invention includes a main conveyor installed substantially horizontally, a detergent scatterer installed above the main conveyor, and a rotating cleaning brush installed behind the spreader and above the main conveyor. , a movable carry-out conveyor disposed continuously at the conveyance end of the main conveyor, and a switching mechanism provided to support at least the main conveyor side of the carry-out conveyor to separate the carry-out conveyor from the conveyance end of the main conveyor; This bedding surface cleaning machine is provided with a return conveyor which is installed below a main conveyor, and whose conveyance start end protrudes from the conveyance end of the main conveyor, and whose protruding portion is inclined upward.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is the fuselage, and its pair of left and right partition walls 2, 2
In between, there are a main conveyor 3, a detergent sprayer 4, 5, a rotating cleaning brush 6, bedding detectors 7, 8, a bedding press conveyor 9, an output conveyor 10, a return conveyor 11,
An auxiliary return member 12, a bedding tray 13, and a drainage tray 14 are provided, respectively. Further, inside the machine body 1, a detergent feeding mechanism 15, a switching mechanism 16, and a drive mechanism (not shown) are provided outside between the partition walls 2, 2. and the rotating cleaning brush 6 are operated.

The main conveyor 3 is installed substantially horizontally. The detergent spreaders 4 and 5 are installed above the main conveyor 3, for example, on the conveyance start end side of the main conveyor 3. These dispersing bodies 4, 5 are formed by attaching injection nozzles 4b, 5b to conduits 4a, 5a that extend across the partition wall. The spray nozzles 4b of the front detergent sprayer 4 can spray detergent over the entire widthwise area of the bedding A with a single width ing. The spray nozzle 5b of the rear detergent sprayer 4 is disposed together with the nozzle 4b so as to be able to spray detergent over the entire widthwise area of the bedding B of semi-double width and double width Y. One of the bedding detectors 7 detects the bedding A and B and is disposed approximately in the center between the partition walls 2 and 2, and the other bedding detector 8 detects the bedding B. and is arranged on one partition wall 2 side. For example, a limit switch is used for each detection body 7. The detergent feeding mechanism 15 also includes a detergent tank (not shown), a pump 15a, and a pair of on-off valves 15 connected to the discharge side of the pump 15a.
b, 15c, etc. One on-off valve 15b communicates with the conduit 4a and opens in conjunction with the detection operation of one of the bedding detectors 7, and similarly, the other on-off valve 15c communicates with the conduit 5a. The valve is opened in conjunction with the detection operation of the other bedding detection body 8. The detergent spray bodies 4, 5 and the detergent feeding mechanism 15 spray the detergent at a pressure of, for example, 6 to 8 kg per square starch (in the case of cotton-filled futons), and the bedding detector 7 detects the detergent according to the width of the bedding. Detergent can be sprayed without waste.

The rotating cleaning brush 6 is installed above the main conveyor 3 and behind the detergent sprayers 4 and 5. The support arm 17 of this brush 6 is rotatable about a pivot 18, and the distance l between the rotating cleaning brush 6 and the main conveyor 3 can be adjusted depending on the thickness of the bedding. This brush 6 is connected to the partition wall 2,
The brush has a length approximately equal to the width between the two, and is rotated in the forward direction relative to the feeding direction of the bedding to brush the surface of the bedding. The bedding press conveyor 9 has detergent sprayers 4 and 5 and a rotating cleaning brush 6.
is located between. This conveyor 9 may be omitted, but in this embodiment, the bedding is conveyed between the main conveyor 3 and the main conveyor 3 to prevent the bedding from getting caught between the main conveyor 3 and the rotating cleaning brush 6. This was provided to make it easier and smoother.

The carry-out conveyor 10 is disposed continuously at the conveyance end of the main conveyor 3, and is connected to the switching mechanism 1.
6. The switching mechanism 16 is provided to support at least the main conveyor 3 side of the carry-out conveyor 10, and separates the carry-out conveyor 10 from the conveyed paper end of the main conveyor 3 during its operation. That is, the switching mechanism 16 is
It is formed from a rotating arm 19 that pivotally supports each roller shaft end of the carry-out conveyor 10, and a cylinder 20 connected to the main conveyor 3 side of this arm 19.
The rotation center of the arm 19 also serves as a roller shaft 21 located at the conveyance end of the discharge conveyor 10. Therefore, when the cylinder 20 raises its rod, the carry-out conveyor 10 is rotated around the roller shaft 21 and separated from the conveyance end of the main conveyor 3, as shown by the two-dot chain line in FIG. It is something that will be done. This allows the bedding that has been washed on one side to fall downward from between the main conveyor 3 and the discharge conveyor 10. In addition, 22 in FIG. 4 is an escape groove of the roller shaft.

The return conveyor 11 is installed below the main conveyor 3. The auxiliary return member 12 is installed between the main conveyor 3 and the return conveyor 11 and protrudes from the conveyance end of the main conveyor 3.
This return member 12 receives the bedding falling from the conveyance end of the main conveyor 3 and guides it to the return conveyor 11 while reversing it. Note that this embodiment shows a case where the auxiliary return member is formed by a belt conveyor in order to further improve the guiding performance. In addition, the bedding tray 13 is transferred to the return conveyor 11.
The drain tray 14 is placed close to the lower surface of the main conveyor 3.
The bedding tray 13 and the drain tray 14 may be omitted, and the drain tray 14 receives the detergent passing down the main conveyor 3.

Note that each of the above-mentioned conveyors is formed by extending a plurality of endless belts between rollers.

In order to wash the surface of the bedding with this surface cleaning machine, first, the switching mechanism 16 is operated to move the carry-out conveyor 10 away from the main conveyor 3, and then one side of the bedding is washed. In other words, by conveying the bedding on the main conveyor 3, detergent is sprayed according to the width of the bedding to the detergent spraying bodies 4, 5, bedding detection body 7,
8 and a detergent feeding mechanism, and then brushed by a rotating cleaning brush 6 after passing through a bedding presser conveyor 9. In this way, the bedding that has been washed on one side is dropped from the conveyance terminal end of the main conveyor 3, guided by the auxiliary return member 12, and delivered to the return conveyor 11. During this transfer, the bedding that has been washed on one side is turned over, that is, turned inside out. Therefore, the return conveyor 11 conveys the bedding to the front side of the machine body 1 with the other unwashed side facing up, and the bedding is taken out into the bedding tray 13. Next, after operating the switching mechanism 16 to arrange the carry-out conveyor 10 so as to be continuous with the conveyance end of the main conveyor 3, the other unwashed surface of the bedding is washed. That is, the rear end portion of the bedding taken out to the bedding tray 13 (positioned at the upper end of the bedding tray 13 due to the above-mentioned return conveyance) is grabbed and raised, and the bedding is placed onto the main conveyor 3 with this rear end portion first. Just put it on.
Then, the other unwashed side is brushed and washed as described above, and the washed bedding is delivered to the discharge conveyor 10 and sent to the rear of the aircraft 1 via this conveyor 10. is discharged.

Note that although the above-described embodiment is configured as described above, the present invention is not limited to this embodiment. For example, the front end side of the main conveyor 3 may be bent diagonally downward to make it easier to place bedding, or an introduction conveyor having the same effect may be arranged. Furthermore, the auxiliary return member 12 may be constructed of a diagonal plate material instead of a belt conveyor, or the starting end of the return conveyor 11 may be constructed by protruding from the conveyance terminal end of the main conveyor and slanting upward. No problem.
In the above embodiment, the carry-out conveyor 10 is rotated to be continuous or separate from the main conveyor 3, but the position of the carry-out conveyor 10 may be changed by moving the whole carry-out conveyor 10 up and down. Furthermore, by moving the entire unloading conveyor 10 in the front-back direction or in the left-right horizontal direction, the unloading conveyor 10
You may also change the position of. Moreover, a plurality of sets of rotating cleaning brushes 6 may be used. In addition, when carrying out the present invention, the specific structure, shape, position, etc. of the main conveyor, detergent sprayer, rotating cleaning brush, unloading conveyor, switching mechanism, return conveyor, etc. shall be Of course, it can be configured and implemented in various ways.

The gist of the present invention described above is the structure described in the scope of the above-mentioned utility model registration claims. Therefore, by disposing an output conveyor that is moved by a switching mechanism at the conveyance end of the main conveyor and by providing a return conveyor below the main conveyor, the main conveyor can be moved while the output conveyor is separated from the main conveyor. Bedding that has been washed on one side can be turned over and conveyed back on the conveyor, so bedding that becomes heavy due to water as one side is washed can be automatically turned inside out without manual intervention. It can be returned to an operating position where it can be loaded onto the main conveyor. This eliminates the need for heavy labor such as moving bedding around, which absorbs water and becomes heavy.
You can easily wash both sides of the bedding. In addition, if you connect an output conveyor to the main conveyor continuously at the end of the conveyance, it is possible to wash only one side of the bedding, so you can use both double-sided and single-sided cleaning.
Easy to use. Moreover, when cleaning both sides,
Since the transport start end of the return conveyor protrudes from the transport end of the main conveyor and is tilted upward, the reversal of the bedding can be carried out reliably with a simple structure. Since no rotating cleaning brush is installed, the machine does not require large dimensions in the vertical direction as a washing machine for relatively thick bedding, and has the advantage that it can be made more compact.
