It is the perspective view which showed typically the garbage cleaning evaluation apparatus in one Embodiment of this invention. It is the perspective view which showed typically the garbage cleaning evaluation apparatus in another embodiment of this invention.

Hereinafter, the dust cleaning evaluation apparatus and dust cleaning evaluation method of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view schematically showing a dust cleaning evaluation apparatus (first embodiment) according to an embodiment of the present invention. The dust evaluation apparatus 10 of the present embodiment has a flooring 1 having a cleaning floor 1a installed on the upper surface of a base 6. On the floor surface 1a, hairs 9 are disposed as dust in the center of the floor 1a. The dust is wiped off with a floor wiper 8 which is a cleaning tool. The floor wiper 8 is attached to a head 5, and the head 5 is connected to the movable mechanism 2 via a connecting shaft 4 and a connecting support portion 3 as a connecting tool. The head 5 and the connecting shaft 4 are pivoted by a shaft-like member 5a erected on the protruding bases on both sides in the center of the upper surface of the head 5 being inserted into a hole of an annular portion 4a formed at the end of the connecting shaft. ing. Although the method of fixing the floor wiper 8 to the head 5 is not shown in detail, a predetermined clamping fixture is provided on the head 5, thereby pinching and fixing the important part of the floor wiper. . Thus, the floor wiper 8 is to prevent removal relative reciprocation m _4.

In this embodiment, the movable mechanism 2 is attached along the rail portion 7 so as to be movable in parallel. Although such an attachment form is not particularly limited, a rail (not shown) is provided on the rail portion 7, and an engaging portion (not shown) of the movable mechanism 2 is engaged in an unfixed state so as to engage with the rail 7. The form to make is mentioned. And this movable mechanism has a drive means (not shown), and when this drive means is energized, it moves in parallel along the rail. For example, a ball screw parallel to the rail may be rotated by a drive motor, and the movable mechanism 2 may be supported by the rail portion 7 via the connecting portion engaged with the ball screw, and may be moved in parallel m _1. . As a modification of the present embodiment, the movable mechanism 2 is not allowed to run on its own, but is installed outside and connected to the drive mechanism 2 by a drive transmission unit such as a wire, belt, chain or the like linked from the drive means. The drive transmission unit may be connected and wound around a rotary shaft provided in the drive unit so that the drive mechanism 2 is retracted and moved. In order to make it further reciprocate, two drive means may be applied, or the drive transmission part may be formed in an annular shape so that the movable mechanism 2 reciprocates depending on the rotation direction.

The dust collection evaluation apparatus of the present embodiment further includes a control means (not shown). This control is connected to the drive means (not shown) in a commandable manner, and the drive means is energized by a command issued from this, and the movable mechanism 2 is parallel to the rail portion 7 as described above. To move. The connection between the control unit and the driving unit may be a wired connection or a wireless connection. When the movable mechanism 2 reciprocates in this way, the head 5 moves along with the connecting tool (the connecting support part 3 and the connecting shaft 4), and the floor wiper 8 is a cleaning tool attached thereto. Performs the same reciprocating motion as the movable mechanism 2. Thus, the floor wiper is slides on repeated floor surface 1a (see reciprocation m _4), continue to collect while attaching the hair 9 which are interspersed thereon.

In the present embodiment, the control means gives a command to the drive means and urges it as described above to reciprocate the movable mechanism 2. At this time, i. Reciprocating distance of the movable mechanism 2, ii. Reciprocating speed of the movable mechanism 2, iii. The angle θ between the head 5 and the connecting shaft 4, vi. Preferably, at least one of the loads pressing the cleaning tool 8 against the floor surface 1 is controlled to be constant. At this time, the above i. And ii. These control items can be controlled by operating the drive means by the control means as described above. On the other hand, control item iii. For the above, it is assumed that the height h of the rail portion 7 is set to be adjustable. For example, the rail portion 7 is fixed to a support frame having a height adjustment mechanism (not shown), and the height adjustment mechanism is operated according to a command from the control means to change the height h, and the rail portion 7 is moved up and down. It can be realized by m ₂ . More specifically, when operating by the control means so as to vary the height h, attachment shaft 3a of the connecting support part 3 if floating state, connection support portion 3 is rotated (see arrow m ₃₎ . As a result, the rail portion 7 moves up and down, and item iii. The angle θ between the head 5 and the connecting shaft 4 can be changed. For the control item iv, the load for pressing the head 5 against the floor surface is controlled by providing a load changing means (not shown) on the connecting shaft 4. For example, the load can be controlled by attaching an air cylinder to the connecting shaft 4 and changing the supply pressure of the air cylinder.

Furthermore, in the present embodiment, the control unit at _least includes the distance of the reciprocating movement m ₁ of the movable mechanism 2, the height h of the movable mechanism 2 from the floor surface 1, and the angle θ between the head 5 and the connecting shaft 4. It is preferable that the two-axis control can be performed within a desired range. By doing in this way, the sliding movement state of the floor wiper can be controlled more accurately, and various evaluation forms can be realized under the control.

  Specific conditions for each control item may be set as appropriate according to the type of target garbage and cleaning tools. For example, in a typical flooring wiper, wiping of hair, dust, and granular dust is assumed. In this case, the reciprocal distance (stroke) in the above item i is preferably 50 to 1500 mm, and more preferably 500 to 1500 mm. Considering the same usage pattern, the reciprocating speed in the above item ii is preferably 100 to 2500 mm / s, and more preferably 500 to 2000 mm / s. The angle θ in the above item iii is preferably 5 to 90 °. The load in the item iv is preferably 0.5 to 5 kgf as a vertical load applied to the cleaning tool 8.

  The method of evaluating the dust collection performance in the present embodiment is not particularly limited. For example, the evaluation is performed based on the amount of dust 9 such as hair collected by sliding movement of the cleaning tool 8 such as the floor wiper. be able to. The collected amount may be measured from the amount of dust collected on the cleaning tool 8 or may be calculated from the amount of dust left on the floor surface 1a. According to the dust collection evaluation apparatus 10 of the present embodiment, comparative evaluation with very little variation can be performed by the parallel movement of the movable mechanism with respect to the floor surface and the parallel sliding of the cleaning tool. The movement of the arm that is wiped and wiped is reproduced as it is, and a mechanism with a joint is adopted as a coupling tool, and the mechanism is rotated and slid like a pendulum (moving in a fan shape). Pushing and pulling (movement like a rag to bend and stretch the elbow) can be considered, but according to this embodiment, the condition does not change from the beginning to the end of the evaluation, and there is little variation due to stable parallel movement The garbage collection performance evaluation suitable for evaluation becomes possible.

  FIG. 2 is a perspective view schematically showing a dust cleaning evaluation apparatus (Embodiment 2) according to another embodiment of the present invention. The present embodiment further includes a photographing mechanism 11 in addition to the configuration of the apparatus of the first embodiment. In the apparatus 20 according to the second embodiment, the floor material 21 is made of a transparent material that hardly generates static electricity. For example, a glass plate can be used, and the base 6 is composed of only a frame, and dust is scattered. The upper surface 21a can be seen through the lower surface 21b on the back side. The photographing mechanism 11 is set so that the photographing lens 11a faces the lower surface 21b of the floor material 21, and the upper surface side of the floor surface is seen through from the lower surface side. Also in the apparatus of this embodiment, the form of reciprocating movement of the movable mechanism 2, the coupling tool (the coupling support portion 3, the coupling shaft 4), and the head 5 is the same as that of the first embodiment, and the cleaning tool (floor wiper) associated therewith. The dust 9 is adhered and collected by reciprocating sliding of 8. By using image processing in the photographing apparatus, dust can be captured by coordinates and image analysis can be performed.

According to the second embodiment, the photographing mechanism 11 is reciprocated in synchronism with the cleaning tool 8 on the floor material 21, that is, so that the surface to be cleaned of the cleaning tool 8 is always set to a position where photographing can be performed. Move m ₅ . Examples of such a reciprocating means include the embodiment shown as a combination of the movable mechanism 2 and the rail portion 7 described above. If an example is shown, the imaging | photography mechanism 11 will be connected and fixed to the support rod 12 fixed to the base 13 by the connection part 11b like what was illustrated. Then, the pedestal 13 may be attached to a rail (not shown) of the rail portion 14, and may be able to run on its own by a driving means (not shown) joined to the pedestal 13, or a driving means (externally installed by a wire or the like ( It may be reciprocated by a not shown). In order to accurately capture the image of the collection surface, the pedestal 13 can obtain an image from directly below by mechanically connecting to the movable mechanism 2 or performing synchronization by electrical control.

  According to the dust evaluation apparatus of the second embodiment, the photographing mechanism 11 attracts the dust 9 such as hair on the upper surface 21a from the lower surface 21b side of the transparent floor surface 21 to the cleaning tool 8 such as a floor wiper. Can be grasped in detail, and the state of adhering can be analyzed in detail in addition to evaluation based on the amount of adhering dust. This makes it possible to elucidate the mechanism by which garbage is collected, and to set the detailed functions of cleaning tools and further improve development, including the type of garbage, the condition of the floor, and the external environment such as humidity and temperature. Can be connected.

  In each said embodiment, although the sheet-shaped cleaning tool was demonstrated to the example about this invention, this invention is limited to this and is not interpreted. For example, in addition to a sheet-like one, a mop-like one or a three-dimensional one can be used to achieve evaluation without variations according to the present invention by adopting a head suitable for it.

  Hereinafter, the present invention will be described in more detail based on examples, but the present invention should not be construed as being limited thereto.

Example 1
The dust evaluation apparatus shown in FIG. 1 was produced. The flooring material used was a wooden flat plate that had been subjected to surface processing applied to ordinary household flooring, the length in the longitudinal direction was about 1000 mm, and the width was about 300 mm. Ten hairs were scattered on the cleaning floor. A 100 mm × 250 mm floor wiper was attached to the head of the dust evaluation apparatus and fixed as shown. The size of the abutting surface between the floor surface and the floor wiper was 100 mm × 250 mm. After being attached to the head, the floor wiper was neutralized. Next, the parallel movement distance was 900 mm, the movement speed was changed as shown in the table below, the angle θ between the head and the connecting shaft was 52 °, the movable mechanism was reciprocated 10 times, and the hair collection test was performed 3 times. Similarly, the test was performed by spraying 10 grains of sesame on the floor surface. The results are shown in Table 1 below.

(Comparative Example 1)
A dust collection test was conducted in the same manner except that the dust evaluation apparatus was used and the head was held by a human hand. The results are shown in Table 1 below. The number of collections in Table 1 is the number of garbage (hair, sesame) that could be collected, and is an average value of three times (N = 3). The variation represents the maximum value-minimum value of the number of collected N = 3.

  As can be seen from the above results, according to the present invention, it is understood that a highly accurate evaluation result with little variation can be obtained in the evaluation of dust collection. In the case of hair, the collection rate is high, so it can be collected either by human or by device, and the difference in variation is small, but in the case of sesame that does not have a very high collection rate, There was a marked difference in the results of the variations. In addition, it is possible to eliminate the individual differences of evaluators and the mental influences of people, improve the quality as quality assessment, and contribute to automation and standardization of evaluation by not involving human work. I understand.

(Example 2 and Comparative Example 2)
In the same manner as in Example 1, dust cleaning evaluation was performed using commercially available floor wipers A to D. The order of the dust cleaning performance evaluated by the number of collected hairs and sesame seeds was such that A was extremely excellent, B was normal, and C and D were slightly poor. As a result of evaluating this by actually cleaning it with the hand of a panel (person), the same order as the above was obtained. On the other hand, as compared with the result of the garbage collection test conducted by human hands as in Comparative Example 1, the results are highly variable and difficult to conclude, and the order may be misaligned.
From this result, according to the dust evaluation apparatus and dust evaluation method of the present invention, it is possible to perform evaluation that reflects the performance when actually applied to cleaning, is highly accurate with no variation, and conforms to the performance in actual use. I understand that there is.
