Description

  The present invention relates to a floor wax coating apparatus mounted on an electric carriage that runs on a floor surface, and in particular, rotates around the same rotation spindle in the horizontal direction below the rotation spindle in which a plurality of wax applicators are suspended. Further, the present invention relates to a floor surface wax coating apparatus which is arranged radially and is configured such that the wax coating tool rotates.

The conventional method of applying the wax liquid to the floor surface is to immerse a mop-like wiping cloth in a container containing the wax liquid, and then move the wiping cloth back and forth and left and right to spread the wax liquid on the floor surface. Has been done.
However, such manual waxing has been problematic in that it takes time and effort, resulting in a difference in workmanship depending on the skill of the operator and a large physical burden caused by moving the wiping cloth.

As a wax application method that replaces the manual wax application using this cloth, a traveling application device that applies a floor coating agent such as wax to the floor while moving on the floor using the power of an electric motor. Several coating methods have been proposed so far.
For example, Japanese Utility Model Laid-Open No. 5-80452 states that “a floor polisher that polishes the floor by rotating the pad (buff) at high speed with a motor while the operator pushes the operating handle with his / her hand. "Floor surface polishing machine having a wax coating function devised to polish the floor surface with a pad while applying wax" (Patent Document 1) is disclosed.
Japanese Patent Laid-Open No. 3-101869 discloses a floor coating agent applicator in which an applicator for applying a coating agent solution to a floor surface is attached to a mobile machine body, while the applicator vibrates up and down. Discloses a floor coating agent applicator provided with an applicator drive mechanism that rotates in accordance with the oscillating motion (Patent Document 2). Further, Japanese Patent Application Laid-Open No. 2009-045171 discloses a method for supplying a wax liquid to a floor surface. A traveling wax coating and drying apparatus (Patent Document 3) is disclosed in which a coating surface of a wax supply and coating apparatus for coating is constituted by a roll of a cylindrical porous resin body having continuous pores.

The invention disclosed in Patent Document 1 utilizes a floor surface polisher that is widely used at present, and impregnates a wax roller provided in front of a circular coating pad rotating at high speed with wax. The wax roller is used to apply wax to the floor surface.
However, when a roller is used as an applicator, excessive wax is applied to both ends of the roller, and uniform application over the entire width of the roller is difficult. However, there is a problem that the coating amount at both ends of the roller becomes excessive and the finished appearance of the wax coating is impaired.

  The invention disclosed in Patent Document 2 applies wax while rubbing the floor surface. When dust that has fallen on the floor surface adheres to the applicator, it subsequently follows the direction of travel of the wax application device. As a result, streaky coating flaws occur and a good finished surface cannot be obtained.

  The invention disclosed in Patent Document 3 uses a cylindrical porous resin body having continuous pores as a coating roll, and the rotation speed of the coating roll is made faster than the traveling speed of the apparatus to increase the floor surface. Although the problem of air bubbles being mixed into the coating film due to air entrainment during rotation of the roll, which was a drawback of the resin roll, has been solved, the wax coating on both ends of the roller, which is a drawback of the roller system, has been solved. The problem of overdose has not been completely solved.

It is a rotary joint that is supplied to a lead-out hole 34 that penetrates the rotary shaft 33 of each wax applicator 30.
The wax distributor 49 includes an upper lid and a lower lid, and the upper lid and the lower lid are fastened with bolts with an O-ring interposed therebetween. The upper lid is threaded to connect with the rotary joint 49 and then drilled. The lower lid has holes in three directions around the liquid reservoir space and its periphery, and is threaded so that it can be jointed with the joint. The wax liquid is supplied from the distributor 49 to the rotating shaft 33 of each wax applicator 30 through the tube 48 in three directions. The tube 48 is provided with an open / close valve such as a ball valve capable of adjusting the flow rate to each wax applicator 30.

The embodiment and operation of the floor wax applicator 2 having three wax applicators 30 shown in FIGS. 3 and 4 will be described in detail below.
A DC geared motor having a hollow shaft output of 200 W and a gear ratio of 30 is attached to the circular substrate 46 of the floor wax coating apparatus 2 as the electric motor 45 that rotates the rotating main shaft 37 that is installed vertically. A rotation main shaft 37 having a lead-out hole 34 through which a wax liquid with an inner diameter of 6 mm flows was inserted into the hollow shaft portion of the electric motor 45, and then the main gear 40 was fastened to the rotation main shaft 37.
Further, the three arms 36 that support the rotation shaft 33 of the wax applicator 30 are radially spaced from the rotation main shaft 37 at intervals of 120 degrees, and the inter-axis distance from the rotation main shaft 37 to the rotation shaft 33 of the wax applicator 30 is set. It was arranged as 237.5 mm.
Each of the three arms 36 holds and rotates an intermediate shaft 39 for transmitting the rotational force of the rotation main shaft 37 to the wax applicator 30 at an intermediate portion and a wax applicator 30 at an end portion. The intermediate shaft 39 is fastened with a slave gear 41 that meshes with a master gear 40 provided on the rotary main shaft 37 and a main pulley 42, and the slave pulley 43 is fastened with the rotary shaft 33. Then, the rotating base 32 to which the wax applicator 30 is attached is fixed to the lower part.

The wax coating member 31a has a white base made of polyester fiber used in a floor cleaning machine for building maintenance as a lining base, and a commercially available wipe (trade name) is glued to the diameter 15 inches (380 mm). A 30 mm-thick one was used and bonded to the bracket board 31b with a hook-and-loop fastener, and then removably screwed to the rotating base 32 fixed to the rotating shaft 33 of the wax applicator 30 with a bolt.
When using a slightly thicker wiping cloth, a large number of holes may be made in the bracket board 31b, and the wiping cloth may be sewn with a string.
Further, the wax application member 31a is not limited to the configuration in which the backing base and the wiping cloth are bonded together as described above. For example, the porous PVA foam resin or the porous urethane foam resin body described in Patent Document 3 is used. The wax application member 31a may be used.
Further, in place of the method in which the wax liquid is directly dropped onto the floor surface from the needle nozzle 35 provided at the lower portion of the rotating shaft 33, the wax-applied member 31a with the central portion cut out is porous having fine continuous pores. A method of embedding a foamed resin body and supplying a wax liquid directly from the lower end of the rotating shaft 33 to the porous foamed resin body can also be suitably implemented in the present invention. Homogeneous wax coating on the floor surface equivalent to the case where the wax solution is spread from the foamed resin body impregnated with the wax solution onto the outer wiping cloth and the wax solution is directly applied to the floor surface from the needle nozzle 35. Is possible.

The wiping cloth may be either a non-woven cloth or a woven cloth. The shape is preferably circular, but may be rectangular as long as it can be applied by impregnating with a wax solution, and the wax applicator 30 is attached to the bracket board 31 according to the shape. If applicable, it can be applied to the reference examples and the practice of the present invention.

The supply of the wax liquid to the wax applicator 30 is penetrated from the wax tank 4 shown in FIG. 1 through the wax supply pump 5, the electromagnetic on-off valve 6 and the tube 48 shown in FIG. The wax solution is sent to the outlet 34 of the wax liquid, and then equally distributed in three directions by the wax distributor 49 attached to the lower end of the rotation main shaft 37, and provided on the upper portion of the rotation shaft 33 of each wax applicator 30. The three wax applicators 30 themselves rotate (rotate) because they are sent to the rotary joint 47 and are appropriately lowered from the end of the rotary shaft 33 to the floor surface through the lead-out hole 34 penetrating through the center of the rotary shaft 33. By the rotation of the three wax applicators 30 around the rotation main shaft 37, the wax liquid is evenly distributed over the entire coating area.
From the wax tank 4 fixed to the electric carriage 1 to the lead-out hole 34 of the rotation main shaft 37 through the supply pump 5, the electromagnetic on-off valve 6 and the tube 48, and from the wax distributor 49 provided below the rotation main shaft 37 through the tube 48. Rotating joints 47 are attached to the upper portion of the rotating main shaft 37, between the rotating main shaft 37 and the wax distributor 49, and to the upper portion of the rotating shaft 33 so that the wax liquid can be reliably supplied to the outlet hole of the rotating shaft 33. . As a result, the tube 48 connecting the wax distributor 49 and the rotary shaft 33 is smoothly and stably dropped onto the floor surface from the lower end of the wax applicator 30 without being entangled with the rotating portion of the floor surface wax application device 2. be able to.

In addition, the arm 36 to which the rotational force transmission mechanism such as the wax applicator 30, the rotation shaft 33, the main and sub gears 40 and 41, the main and sub pulleys 42 and 43, and the belt 44 is attached is radially attached from the rotation main shaft 37. Therefore, it is preferable because the degree of freedom of attachment of the tube 48 connecting the wax distributor 49 and the upper end of the rotary shaft 33 is increased and the weight of the apparatus can be reduced.
Since the wax tank 4 is always disposed above the floor surface, the wax liquid may fall from the lower end of the wax applicator 30 to the floor surface due to the siphon effect even when the wax operation is stopped. Therefore, the electromagnetic valve 6 is provided between the wax supply pump 5 and the tube 48 in order to prevent dripping of the wax liquid on the floor surface due to the siphon effect. Any electromagnetic valve 6 can be used as long as it can prevent dripping of the wax liquid due to the siphon effect.
In addition, when the wax application operation is finished and moved to the next application location, when the wax application device 2 is pulled up while being rotated by the actuator 3, a few drops of the wax liquid fall and splash, and the applied floor surface is soiled. Occurs. For this reason, in this invention, the fall and scattering of a wax liquid are suppressed by mounting | wearing the lower end of the rotating shaft 33 to which said wax applicator 30 was attached with the needle nozzle 35. FIG. As a result of the test, if the diameter of the dripping port of the needle nozzle 35 is 0.2 to 0.3 mm, the surface tension is superior to the gravity of the wax liquid at the tip of the needle nozzle 35. It was found that can be deterred.

When the floor wax coating apparatus 2 of the reference example is extended to the floor surface by extending the rod of the electric actuator 3, and when the rotating spindle 37 is rotated by the electric motor 45 while dripping the wax, the rotational force is applied by the rotational force transmission mechanism. An arm mounted on the rotary main shaft 37 through a rolling bearing 38 by the reaction between the floor surface and the wax coating tool 30 caused by friction between the floor 30 and the wax coating tool 30 as the wax coating tool 30 rotates by being transmitted to the rotary shaft 33 of the tool 30. 36 rotates in the direction opposite to the rotation direction of the wax applicator 30. In this way, the wax applicator 30 connected to the rotation main shaft 37 by the rotational force transmission mechanism rotates (rotates), and the arm 36 to which the wax applicator 30 is attached can be rotated around the rotation main shaft 37. .
At this time, depending on the state of the floor to which the wax is applied, the pressure at which the lower surface of the wax applicator 30 comes into contact with the floor is applied by the weight of the floor wax application device 2 or by the extension of the rod of the actuator 3. Therefore, it can be controlled appropriately.
The rotation speed at which the wax coating tool 30 rotates around the rotation main shaft 37 on the floor surface is the rotation number of the rotation main shaft 37, the rotation speed of the wax coating tool 30, and the friction state between the floor surface and the wax coating tool 30. It depends on the pressing force of the wax applicator 30 on the floor surface. In addition, since the ratio of the rotation speed of the wax applicator 30 itself and the rotation speed of the arm 36 around the rotation main axis can be changed by the respective gear ratios of the main gear 40 and the slave gear 41, and the main pulley 41 and the slave pulley 42, The rotation ratio of the rotation main shaft 37 and the rotation speed of the wax applicator 30 can be made different by appropriately selecting the gear ratio between the main and sub gears and the gear ratio between the main and sub pulleys.
As described above, the rotation speed of the arm 36 around the rotation main axis and the rotation speed of the wax applicator 30 are different from each other because the rotation speed of the arm 36 around the rotation main axis and the rotation speed of the wax application tool 30 are the same. In this case, the wax applicator 30 does not rotate when viewed from the arm 36.
That is, the three wax applicators 30 are rotated around the rotation main shaft while being fixed to the arm 36, and the wax applicator 30 rotates around the rotation main shaft while rotating (spinning). This is because the improvement of the wax application performance by the heavy rotation mechanism cannot be obtained.

A wax coating experiment was performed on the floor surface using the traveling wax coating apparatus 1 equipped with the wax coating apparatus 2 of the first reference example. In the experiment, the rotational speed of the electric motor 45 is set to 60 to 120 rpm, the pressing force to the floor surface of the floor surface wax coating apparatus 2 is set to 10 to 25 kgf, and the wax coating amount is set to 5 to 10 g / m <2>. It was performed by applying wax to the floor surface of the plastic tile (P tile) at a traveling speed of 1 to 2 km / h of the apparatus 1.
In addition, the acrylic urethane copolymer resin type commercial item (Rinley, brand name Permo R-1) was used for the wax.
as a result,
1. The wax could be applied uniformly and evenly over the entire surface.
2. The left and right ends in the direction of application were not excessively applied, and even when overcoated, the wax could be applied uniformly to such an extent that the boundary between the ends could not be identified.

As described above, in comparison with the conventionally proposed floor wax coating apparatus, excellent coating performance was obtained in the horizontal direction below the rotating spindle 37 that was suspended. A plurality of wax applicators 30 rotating around are arranged radially, and the plurality of wax applicators 30 are configured to rotate respectively, and a wax liquid is dropped from the center of the wax application member 31a. There is. That is, if a wax is applied to the floor surface by rotating one wax applicator having a diameter corresponding to the application area width, the rotation axis of the wax applicator and the rotation of the wax applicator itself are caused by rotational shake. Although it is difficult to finish the entire width of the coating area to a uniform coating surface, in this reference example , each of the wax applicators 30 is counteracted by rotating and rotating around the rotation spindle 37 by rotating the plurality of wax applicators 30 around each other. Thus, the uniformity of coating is improved, and the followability to the unevenness of the floor surface is improved, and a more uniform wax coating effect is obtained.
Further, by dropping the wax liquid from the center of the wax coating member 31a, the wax liquid is allowed to permeate the entire surface of the wax coating member 31a without being scattered around the wax coating member 31a. When the wax is applied to the floor surface with a single wax applicator having a diameter corresponding to the above, the amount of wax liquid dripping from the center is inevitably large, and the permeation to the peripheral part is also uniform. It becomes difficult, and the amount of the wax applied differs between the central portion and the peripheral portion of the wax applicator, resulting in uneven coating.
However, in the wax application device 2 of the present reference example , the same amount of wax liquid is distributed to the plurality of wax applicators 30, and the diameter of the wax application member 31a also has a diameter corresponding to the application area width. Since it is smaller than the tool, the permeation of the wax liquid into the peripheral portion is performed quickly, and the wax applicator 30 rotates even if there is a variation in the permeation speed and the application amount of the wax for each wax application member 31a. The effect of leveling this by the rotation around the main shaft 37 is obtained. Further, even if the wax liquid is dropped directly on the floor surface from the tube 48 branched in three directions by the wax distributor 49 between the radially arranged arms 36, it is suitable for the purpose of this reference example. It is more preferable to drop the wax liquid from the lower end of the rotating shaft 33 of the wax applicator 30.

  Further, in addition to the rotation of the wax applicator 30 and the rotation around the rotation main shaft 37, the pressing force to the floor surface of the wax applicator 30 is adjusted by the extension amount of the rod of the electric actuator 3 that suspends the entire wax applicator 2. As a result, uniform wax coating can be obtained, and smooth running and coating can be achieved even if there are large irregularities on the floor surface. At this time, the pressing force on the floor surface of the wax applicator 30 can be calculated from the total weight of the wax application device 2 by measuring the contraction allowance of the coil spring 12, so that the floor surface wax application device 2 to be used is replaced. Even if the working conditions change, it is possible to carry out the coating work with the target appropriate pressing force.

In the first reference example, the case where the number of the wax applicators 30 is three has been described. However, the present invention can be applied to the case where the number of the wax applicators 30 is two, five, and six.

Reference example 2

In the reference example 1 described above, the rotational force transmission mechanism that transmits the rotational force of the rotary shaft 37 that is suspended is transmitted to the rotation shaft 33 of the wax applicator 30. However, as shown in FIG. 6, the distance between the main pulley 42 fastened to the rotating main shaft 37 and the sub pulley 43 fastened to the rotating shaft 33 of the three wax applicators 30 is 1. Similar to Reference Example 1, the rotation of the wax applicator 30 and the rotation spindle can be achieved by suspending either a double-sided toothed belt, a flat belt, or a sprocket chain (see FIG. 6, indicated by reference numeral 44). A double rotation with the surrounding rotation is obtained.

As a first embodiment of the present invention, a case where four wax applicators 30 are arranged radially at intervals of 90 degrees around the rotation main shaft 37 will be described. Figure 6 is a structural view as seen from the rear of the electric dolly 1 wax coating paint with device 2 of the first embodiment, FIG. 7 shows a block diagram of the torque transmitting mechanism floor surface waxing device 2 .
This Example 1 Reference Example 1 differs, as seen in FIG. 7, the rotational force to the two wax applicator 30 attached to the opposite one the two arms 36 of the four arms 36 The idler gear 50 is provided between the main gear 40 and the slave gear 41 of the transmission mechanism, and the other mechanisms are the same as those of the wax coating apparatus 2 of the reference example 1.
In this embodiment, by providing the idler gear 50, the rotational directions of the two wax applicators 30 incorporating the idler gear 50 and the two wax applicators 30 not incorporated are reversed, Furthermore, the rotational rotation speed of the wax applicator 30 can also be varied by two. In the same manner as in Reference Example 1, the arm 36 disposed via the rolling bearing 38 provided on the outer periphery of the rotating main shaft 37 suspended by the reaction caused by the friction between the rotating wax applicator 30 and the floor surface is rotated. By doing so, the four wax applicators are rotated around the rotation main shaft 37.
That is, the apparatus of Example 1 is the following floor wax coating apparatus.

Furthermore, the remaining one to three units of the wax applicator (30) are B rotational force transmission mechanisms that transmit the rotational force of the rotational main shaft (37) in the reverse rotation direction,

A floor wax coating apparatus characterized by being configured to rotate (spin) in a direction. "
Were subjected to coating with the same floor as in Reference Example 1 by waxing device 2 of this first embodiment, the wax coating apparatus 2 of the first embodiment, as compared with that of Example 1, with a wax coating member 30 The number of contact points of the wax applicator 30 per unit floor area is increased, the application is further uniformized, and the paint areas generated at the left and right ends in the traveling direction of the electric carriage 1 are increased. The pitch of the wavy trajectory (see FIG. 10) was also narrowed, and the result was that the end of the coating area was closer to a straight line.

In Reference Examples 1 and 2 and Example 1 , the main gear 40 is fastened and fixed to the rotation main shaft 37, and the arm 36 is freely rotated by mounting the arm 36 on the outer periphery of the rotation main shaft 37 via a rolling bearing 38. Although is, in the second embodiment, as shown in FIG. 8, the fastening arm 36 to rotate the main shaft 37, and fixed, rotatably mounted main gear 40 to the rotating spindle.
The following floor wax application device.
“Four arms (36) are attached radially in the horizontal direction below the rotating spindle (37), and the wax applicator (30) is attached to each end of the arm (36). 4 units are arranged to freely rotate (spin),
One to three of the wax applicators (30) are first rotational force transmission mechanisms that transmit the rotational force of the rotational main shaft (37) in the direction of forward rotation.
That is, a main gear (40) provided on the rotating main shaft (37) provided vertically, and a slave gear (41) provided on an upper portion of the intermediate shaft (39) provided vertically on the intermediate portion of the arm (36). A main pulley (42) provided below the intermediate shaft (39), a slave pulley (43) provided on a rotary shaft (33) to which the wax applicator (30) is mounted, and the master slave pulley It is configured to rotate (spin) in the direction of forward rotation by a first rotational force transmission mechanism formed by a belt (44) connecting between the two,

The floor surface wax coating apparatus is configured to rotate (spin) in the direction of . "
Therefore, when the electric motor 45 is rotated, the arm 36 starts to rotate due to the rotation of the rotation main shaft 37, and at the same time, the slave gear 41 rotates around the main gear 40 fixed to the substrate 46. When the slave gear 41 rotates, the intermediate shaft 39 to which the slave gear 41 is fastened rotates, and at the same time, the main pulley 42 attached to the intermediate shaft 39 also rotates. When the main pulley 42 rotates, the sub pulley 42 connected to the belt 44 and the rotation shaft 33 of the wax applicator 30 to which the sub pulley 42 is fastened rotate, and the wax applicator 30 fastened to the rotation shaft 33 is rotated. The rotation of the wax applicator 30 and the rotation around the rotation main shaft 37 are realized. Since the other mechanisms are the same as those of the wax application device 2 of the first embodiment, the rotational directions of the wax applicator 30 on the side where the idler gear 50 is attached and the wax applicator 30 on the side where the idler gear is not attached are Reverse.
In this case, in order to suppress the load of the electric motor due to the reaction caused by the difference in the rotation speed, the main gear 40, the slave gear 41, and the main pulley are set so that the rotation speed on the floor surface of the four wax applicators 30 is substantially the same. 42, it is preferable to select the ratio of 43 teeth of the sub pulley as appropriate.

Reference example 3

In this reference example 3 , the above-described reference examples 1, 2 and example 1 rotate the wax applicator 30 around the rotation main shaft 37 by utilizing the reaction caused by the rotation of the plurality of wax applicators 30 and the friction with the floor surface. Unlike the double rotation mechanism, the rotation of the wax applicator 30 and the rotation of the arm 36 on which the wax applicator 30 is mounted around the rotation main shaft 37 can be individually controlled. The configuration is shown in FIG.

As shown in FIG. 9, the wax coating apparatus 2 of the present reference example 3 is provided with an electric motor 45 for rotating the rotation main shaft 37 and an electric motor 45 ′ for rotating the arm 36 on the substrate 46, and the arm 36 is rotated. The spur gear 52 attached to the electric motor 45 ′ and the spur gear 53 mounted on the rotary main shaft 37 via the rolling bearing 38 are meshed with each other, and the spur gear 53 is also in contact with the rotary main shaft 37. The arm 36 is fastened with bolts 38 via bolts, and is a mechanism that freely rotates with respect to the rotation main shaft 37.
Further, a bevel gear 54 is attached to the lower part of the arm 36, and the bevel gear 55 in which the bevel gear 54 and the rotation shaft 56 are orthogonal to each other arranges the four wax applicators 30 around the rotation main shaft 37. Four of the four bevel gears 55 are arranged at intervals, and the shaft 59 of each of the four bevel gears 55 is supported and suspended by two brackets 60 incorporating a rolling bearing 38 in parallel with the arm 36. A bevel gear 56 is attached to the tip of the shaft 59, and two bevel gears 57 and 58 that are paired with the bevel gear 56 are attached to the rotary shaft 33 that rotates the wax applicator 30.
Two bevel gears 57, 58 attached to a rotary shaft 33 that rotates the wax applicator 30.
Of these, the upper bevel gear 57 is fixed to the rotary shaft 33, while the lower bevel gear 58 is rotatably mounted on the rotary shaft 33 via a rolling bearing 38. On the contrary, if the lower bevel gear 58 is fixed to the rotary shaft 33 and the upper bevel gear is rolled on the rotary shaft 33 and mounted freely via the bearing 33, the rotation direction of the wax applicator 30 is reversed. Can do.
In FIG. 9, the wax liquid supply mechanism is the same as that in the first embodiment, and thus the description thereof is omitted.

In the case of the wax application device 2 described in Reference Examples 1 and 2 and Example 1 , the pressing force on the floor surface of the wax applicator 30, the rotational speed around the rotation main shaft 37, the rotation of each wax applicator 30 ( Rotation) The reaction force due to friction between the wax applicator 30 and the floor surface depends on the speed difference, and it is difficult to arbitrarily control the rotation speed around the rotation spindle, whereas in the case of the fifth embodiment, Since the rotation of the rotation spindle 37 and the rotation of the wax applicator 30 are performed by separate electric motors 45 and 45 ', the rotation speed of the wax applicator 30 and the rotation speed around the rotation spindle can be arbitrarily controlled. Therefore, it is possible to select an optimum application condition at each application site.

The wax applicator 2 of the present reference example 3 includes four wax applicators 30 around the rotation main shaft 37, and the rotation shaft of the wax applicator 30 is combined with a bevel gear that is orthogonal to the rotational force of the electric motor 45 '. , And the rotation of the two wax applicators 30 arranged in a point-symmetrical position with respect to the rotation main shaft 37 are opposite to each other, and the floor surface by the rotation of the four applicators 30 Reactions due to friction will cancel each other.
That is, only the rotation of the wax applicator 30 does not cause a force to rotate the wax applicator 30 around the rotation main shaft 37. Accordingly, the rotation of the wax applicator 30 around the rotation main shaft 37 transmits the rotation of the electric motor 45 ′ to the arm 36 via the spur gears 52, 53, and the arm 36 can be freely moved with respect to the rotation main shaft 37. By being rotatably mounted, the wax applicator 30 attached to the arm 36 rotates around the rotation main shaft 37.
Also, from the configuration of the wax application device shown in FIG. 9, the electric motor 45 ′ is removed, and the rotational direction and the rotational speed of the two bevel gear groups mounted on the rotary shafts 33 suspended from both ends of the arm 36 are set. In other words, even if there is only one electric motor 45 that rotates the rotation main shaft 37, the rotation of the wax application tool 30 itself and the periphery of the rotation main shaft 37 are caused by the reaction of friction with the floor surface of the wax application tool 30. A double rotation with 30 rotations is obtained.
In this reference example 3 , the case where the wax applicator 30 is arranged in four directions at intervals of 90 ° from the rotation main shaft has been described. However, the wax applicator 30 is arranged in three directions at intervals of 120 ° from the rotation main shaft 27. It is also possible to arrange them in five directions at intervals of 72 °.

The wax coating apparatus 2 of the present invention rotates around the rotation main shaft with a radius between the rotation main shaft 37 on which the plurality of wax applicators 30 are suspended and the rotation shaft 30 of the wax applicator 30 as a radius, and The applicator moves in the traveling direction of the electric cart 1 while rotating around the radius. Accordingly, the trajectory of the left and right ends of the wax application region by the wax application device 2 of the present invention is not a straight line, and as shown in FIG. 10, the cycloid curve is compressed in the traveling direction and the shape near the vertex is cut continuously. Draw the waveform.
The pitch of the locus, the width from the peak to the valley, the number of wax applicators 30, the number of rotations around the rotation main axis of the wax applicator 30, the radius of the trajectory drawn by the wax applicator 30 rotating around the rotation main axis, It depends on the traveling speed of the carriage 1. The smaller the width d of the unapplied portion, the more efficiently the wax application operation to the floor surface.
The width d of the portion where the wax is not applied includes the wax application speed V (km / h), the rotation speed R (rpm) around the rotation main axis of the wax application tool 30, and the rotation locus around the rotation main axis at the end of the wax application tool 30. The radius r and the number S of wax applicators 30 can be calculated.
As shown in FIG. 11, when a plurality of wax applicators 30 rotate around the rotation main shaft 37, the rotation center of the preceding wax applicator 30 a and the rotation of the end of the wax applicator 30 around the rotation main shaft are rotated. When the line connecting the center of the trajectory comes to a position orthogonal to the traveling direction of the electric carriage 1, the wax application width becomes the widest, and then the electric carriage 1 moves by a distance x and the subsequent wax coating tool 30b rotates. When the line connecting the center of the center and the center of the rotation locus around the rotation main axis of the end of the wax applicator 30 comes to a position orthogonal to the traveling direction of the electric carriage 1, the wax application width becomes the widest again. Therefore, the wax application width is the narrowest at the intermediate point of the movement distance x, and the position is the intersection Q of the rotation trajectories around the rotation main axes of the two wax application tools 30 at the distance x.
Now, let r be the radius of the rotation locus around the rotation main axis at the end of the wax applicator 30, and the line connecting the centers O and O ′ of the rotation trajectories around the rotation main axes at the ends of the two wax applicators 30a and 30b from the intersection Q. Is the length of the perpendicular line up to y, and θ is the angle between the line Y connecting the intersection point Q with the center O of the rotation locus around the rotation main axis of the end of the wax applicator 30 and the perpendicular line y. The difference in coating width between the widest point (mountain) and the narrowest point (valley), that is, the width d of the portion where the wax is not applied is d = ry− ………………………… 1)
y = rcosθ …………………………… (2)
θ = sin−1 {(x / 2) / A} (3)
Given in.

On the other hand, if the traveling speed of the electric carriage 1 is V (km / h), the moving distance (speed) per second is 10,000 / 36 × V (mm).
Further, when the rotation speed of the wax applicator 30 around the rotation main shaft is R (rpm) and the number of the wax applicators 30 is S, the angle formed by the adjacent wax applicators 30a and 30b with the center of the rotation main shaft 37. Is 360 / S (degrees), and the time t (seconds) until the preceding wax applicator 30a leaves the apex and the subsequent wax applicator 30b reaches the apex is a moving angle at a rotational speed R / 60 per second. 360 / S degree divided by
t = (360 / S) ÷ (R / 60)
It becomes.
The distance x traveled by the traveling wax coating apparatus 1 during time t is:
x = (360 / S) ÷ (R / 60) × 10000/36 × V (mm)
= 6 × 10 7 × V / SR ……………………… （4）
It becomes.
Therefore, in the above equations (1) to (4), the number S of the wax applicators 30, the radius r of the rotation locus around the rotation main axis of the wax applicator 30, the rotation speed R around the rotation main axis of the wax applicator 30, If the value of the traveling speed V of the traveling wax coating apparatus 1 is given, the width d of the portion where the wax is not applied can be obtained.

Now, when trying to apply wax to the floor surface where the width of the portion where the wax is not applied is d by the wax applicator whose radius of rotation around the rotation main axis at the end of the wax applicator 30 is d, Equation (3) Leads to the condition that x must be constant. Since x is defined by the equation (4), the traveling speed V of the electric carriage 1 and the rotational speed R around the rotation main shaft of the wax applicator 30 are proportional to each other under a constant x condition. Therefore, it can be understood that the rotational speed R around the rotation main axis of the wax applicator and the number S of the wax applicators are in an inversely proportional relationship.
The wax coating in the room with the wax coating device 2 mounted on the electric carriage 1 generally has a short coating work distance in a straight line and the frequency of the folding work is very high. There are many. Therefore, in the electric cart 1 equipped with the wax application device of the present invention, the supply voltage to the electric motor 45 so as to reduce the rotational speed R around the rotation main axis of the wax applicator in proportion to the traveling speed V of the electric cart 1. The width d of the portion where the wax is not applied is set to a predetermined value, and uniform application of the wax to the floor surface is efficiently performed, and the amount of power supplied from the battery 14 to the electric motor 45 is suppressed. Consideration is given so that a larger area of wax can be applied.

  The length in the running direction of the portion where the wax cannot be applied is also about the running speed V of the electric carriage, the number S of wax applicators, the rotational speed R around the rotation spindle of the wax applicator, and the rotation spindle 37 around the end of the wax applicator. It depends on the radius A of the rotation trajectory. When the number S of wax applicators is as small as two, the number S of wax applicators and the rotational speed R around the rotation main axis of the wax applicator are in an inversely proportional relationship in the equation (4). By increasing the rotation speed around the rotation main axis of the wax applicator, the width d and length of the portion where the wax cannot be applied can be reduced.
