Description

  The present invention relates to a floor wax peeling apparatus that can efficiently and easily remove wax applied to a floor of a store or the like, dirt attached to the floor, and the like.

Patent Document 1 describes a deposit removal method that includes an injection device on the abdomen of a vehicle body and can remove deposits on a floor surface or a road surface by a manual push operation.
Japanese Patent Laid-Open No. 2002-4234

In the deposit removal method described in Patent Document 1, a plurality of injection nozzles are swung in a direction substantially parallel to the floor surface or reciprocated in a substantially horizontal direction to inject crushed pieces together with a gas flow. However, since the spray nozzle is reciprocated, the moving speed of the spray nozzle gradually decreases at the left and right movable ends, and after suspending, it is accelerated again. Since the moving speed is slow at the end, there is a problem that the deposit on the floor surface is peeled off more than the central movable area, and uniform planar peeling is impossible.
In particular, in the wax peeling operation on the floor surface, it is desired to peel the applied wax layer to a uniform thickness without leaving the applied wax layer to some extent. In the reciprocating spray nozzle configuration, a dent is formed at the boundary between the part where the wax layer is peeled off and the part where the wax layer is not peeled. Since the movable end portion of the injection nozzle is located further on the portion that is recessed at the first time because the peeling operation is performed, the recess becomes deeper and the wax that does not need to be peeled is peeled off. was there.
It is an object of the present invention to provide a floor wax peeling device that can peel a wax material applied to a floor surface or the like as uniformly as possible.

  In a floor surface wax peeling apparatus that self-runs while spraying particles 3 together with a gas flow 2 from a spray nozzle 1 that can swing back and forth to the left and right, and a wax material Fw on the floor surface Y. The injection nozzle 1 is located at the extreme end position Cm of the left and right end region C1 in the left and right end region C1 of the left and right reciprocating swinging region CA of the injection nozzle 1 and in the intermediate portion from the tip of the injection nozzle 1 to the floor surface Y. It is set as the structure of the floor surface wax peeling apparatus which provides the shielding member S which reduces gradually the collision amount to the floor surface Y of the injected gas flow 2 and the fluid 3 as it approaches.

  Further, in the left and right end region C1 of the injection nozzle 1, the amount of collision of the gas flow 2 and the particles 3 with the floor surface Y is reduced until the predetermined position Cx where the left and right oscillation of the injection nozzle 1 approaches the extreme end position Cm. Between the predetermined position Cx and the extreme end position Cm, a shielding member S is provided that keeps the gas flow 2 and the amount of collision of the granules 3 with the floor surface Y at a substantially constant amount while gradually decreasing. It is set as the structure of the floor surface wax peeling apparatus of claim | item 1.

According to the first aspect of the present invention, the right and left end region C1 of the left and right reciprocating swing region C of the injection nozzle 1 and the right and left end region C1 of the injection nozzle 1 at the intermediate portion from the tip of the injection nozzle 1 to the floor surface Y are provided. Is provided with a shielding member S for gradually reducing the amount of collision of the gas flow 2 and the particles 3 with the floor surface Y as approaching the extreme end position Cm, and in particular, the horizontal oscillation speed of the injection nozzle 1 is slow. The amount of collision of the gas flow 2 and the particles 3 that collide with the floor surface Y is gradually decreased by the shielding member S as it approaches the left and right end region C1 and the farthest end position Cm where the left and right swing speed becomes slower. Therefore, the wax material Fw can be peeled off substantially uniformly over the entire left and right reciprocating rocking area CA of the injection nozzle 1.
Moreover, the peeling depth of the wax material Fw in the left and right end region C1 of the right and left reciprocating swing region C of the injection nozzle 1 can be easily adjusted by the shielding member S having a simple configuration.

  According to the second aspect of the present invention, in the left and right end region C1 of the injection nozzle 1, the gas flow 2 and the bed of the granule 3 are obtained until a predetermined position Cx where the left and right oscillation of the injection nozzle 1 approaches the extreme end position Cm. The amount of collision with the surface Y is gradually reduced, and the amount of collision between the gas flow 2 and the granular material 3 with the floor surface Y is maintained at a substantially constant amount from the predetermined position Cx to the extreme end position Cm. Since the member S is provided, the left and right end region C1 of the left and right reciprocating rocking area CA when performing the peeling operation of the next row after performing the peeling work in the left and right reciprocating rocking area CA width of the injection nozzle 1. In the case of performing a peeling operation in which a part of the polymer is peeled off, even if the peeling of the polymerized portion results in a double peeling between the forward path and the return path, the polymerization is performed on the floor surface Y that has been initially peeled in the forward path and the return path. The level difference from the double peeled floor surface that has been peeled off is small, and the wax material is peeled uniformly over the entire floor surface Y. It can be carried out.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows the operation principle of the floor wax peeling apparatus using the present invention, and the structure thereof will be described together with FIG.

This electromagnetic clutch is for enabling the left and right front wheels 10 to roll freely when turning or changing the direction of the floor wax peeling device. The operator pushes and pulls the handle 44 to add a caster angle. By changing the direction of the rear wheel 11, it can be easily routed with a light force.
At the front lower side of the vehicle body 6, a blast injection recovery device B capable of peeling and removing the floor wax is projected forward, the blast injection recovery device B is grounded, and the particles 3 are removed from the injection nozzle 1 provided inside. The floor wax can be peeled off or removed by being jetted together with the gas flow 2 and running while colliding with the floor surface Y.
The granules 3 of the floor wax peeling apparatus of the present invention are resin beads J obtained by granulating resinous coarse fragments into a predetermined size, and the gas stream 2 is supplied from a separate compressor C by an air hose 19.

Further, the blast jet recovery device B is provided with a vacuum recovery unit 5 for collecting the injected resin beads J and the wax particles W separated or removed by the jetting collision. The grains W are collected again into the granule tank 15. The granule tank 15 is provided with a net-like separation plate 16 capable of separating the resin beads J and the separated wax particles W, and the reusable resin beads J fall below the separation plate 16 and become dust. The resin beads J that cannot be reused and the wax particles W that have been peeled off are sucked into the vacuum device 17 provided at the rear of the particle tank 15, and the dust box 18 provided at the lower end of the vacuum device 17 and capable of being pulled out rearward. Accumulated in. Reference numeral 51 denotes a front cover that covers the blast injection recovery apparatus B, and reference numeral 52 denotes a side cover of the vehicle body 6.
A fan 22 is provided on the upper portion of the vacuum device 17, and the air in the vacuum chamber 20 is sucked through the filter D and discharged to the outside. The vacuum chamber 20 and the particle tank 15 are in communication with each other. When the inside of the vacuum chamber 20 becomes negative pressure, the inside of the particle tank 15 also becomes negative pressure, and the resin beads J and the wax particles W are discharged from the blast jet recovery device B. Is sucked upward of the granule tank 15. At that time, the reusable resin beads J fall downward by the sorting plate 16 and are again sprayed from the spray nozzle 1. Further, the finely divided resin beads J and wax particles W that cannot be reused are not dropped because they are light in mass, and are sucked to the vacuum chamber 20 side.

  The vacuum fan 22, the self-propelled motor M, and the electrical control unit of the floor wax peeling machine are powered by AC 100 to 110 V for general households, and each operation switch is provided on the upper frame 14. It can be done according to the kind. 23 is a power switch, 24 is a travel switch for turning on and off the motor M, 25 is a blast switch for turning on and off the injection of the resin beads J, and 26 is a jet of compressed air P from the inside of the filter D in the vacuum device 17 This is a cleaning switch that can eliminate clogging of the filter D. Reference numeral 27 denotes a travel speed adjusting volume, and 28 denotes an hour meter.

In front of the lower frame of the vehicle body 6, a pair of left and right injection devices 4 are provided inward, covered with a blast box 54 with a bottom opening, and the gas flow 2 and resin beads J injected therein and the wax particles peeled off. A blast injection recovery device B configured to be able to recover W is disposed, and the blast injection recovery device B is configured in a thin box shape that is inclined forward and downward when viewed from the side, so that a wax peeling operation having substantially the same width as the lateral width of the vehicle body 6 can be performed. Is possible. When the blast jet recovery device B is disposed in front of the vehicle body 6, it is possible to perform wax peeling as far as the wall in the work progressing direction, and efficient wax peeling work can be performed.
The blast jet recovery apparatus B can be moved up and down around the lifting fulcrum shaft 30 by manually operating the lifting lever 29 up and down. The elevating fulcrum shaft 30 is provided on an elevating base 31, and the elevating base 31 is pivotally supported 32 on a base swinging shaft protruding forward from the left and right central portion of the lower frame 12. Accordingly, the blast jet recovery device B is configured to be integrally movable up and down and swingable left and right. The blast injection recovery device B is lowered and grounded by its own weight. A brush-like brush 45 and an elastic sheet 46 are attached to the grounding portion of the blast jet recovery device B, and the brushes 45 and the elastic sheet 46 are grounded for fine irregularities on the floor surface, and the injected resin beads In this configuration, J does not scatter from inside the blast jet recovery apparatus B to the outside. A pair of left and right rollable grounding wheels 7 are provided at the lower rear of the blast injection recovery device B. The grounding wheel 7 can adjust the grounding wheel 7 in the vertical direction by turning the bolt 33, that is, the grounding condition of the bottom surface of the blast injection recovery device B when the grounding wheel 7 is grounded can be adjusted. The bolt 34 is a lock bolt that prevents the position of the bolt 34 from changing after the grounding wheel 7 is adjusted.

Thus, since the blast injection recovery device B can be moved up and down integrally with the vehicle body 6 and can be swung left and right, the bottom surface of the blast injection recovery device B is deformed, curved, or uneven on the floor surface. On the other hand, the contact with the ground surface is surely achieved, the gap with the floor surface Y is not formed, and the resin beads J and the wax particles W are not scattered outside the blast jet recovery apparatus B.
Further, the grounding wheel 7 can always keep the distance between the bottom surface of the blast injection recovery device B and the floor surface, and can make the blast injection recovery device B bottom surface faithfully follow the ground according to the shape of the floor surface. Furthermore, since the grounding wheel 7 is configured to be adjustable in the vertical direction, it is possible to adjust the grounding pressure at the bottom surface of the blast injection recovery device B according to the floor surface state.

Above the blast injection recovery device B, a drive motor KM for driving the injection device 4 to the left and right is attached to the motor base 48, and the drive motor KM is superposed on the longitudinal width A of the blast injection recovery device B in a side view. Arranged.
Thereby, the front-rear width A1 of the entire blast injection recovery apparatus B can be configured to be thin and compact, and the blast injection recovery apparatus B can be downsized. The output shaft of the drive motor KM is attached rearward, and the drive is transmitted in the order of the drive arm 35, the intermediate arm 36, the slide plate 37, the swing shaft arm 38, and the swing shaft 39. Projected into device B. In this configuration, the pair of left and right injection devices 4 can be swung by a single drive motor KM. The pair of left and right injection devices 4 are connected so that when one injection device 4 swings to the right, the other injection device swings to the right. Each rotating part is provided with a bearing (not shown), and the injection device 4 can be swung left and right with a light driving force. A nozzle arm 40 having the injection nozzle 1 attached to the lower end is fixed to the front end of the swing shaft 39, and a resin bead J supply hose 41 using a flexible resin material or vinyl material at the middle portion thereof and the gas flow 2 A supply hose 42 is connected.
The pair of left and right resin bead J supply hoses 41 are inserted into the blast injection recovery device B from the inner position in the vicinity of the swing shaft 39 on the upper surface of the blast injection recovery device B. 4 is connected to the middle part. The supply hose 41 is of a transparent type so that the resin beads J can be seen flowing.
On the other hand, the supply hose 42 for the compressed air 2 is inserted into the blast injection recovery device B from the outer position near the rocking shaft 39 on the upper surface of the blast injection recovery device B, wound in a letter-shaped form, and then injected into the injection device 4. Connected to the middle part.

  By winding the supply hoses 41 and 42 in a square shape and arranging them, the supply hoses 41 and 42 are not burdened even if the jet nozzle 1 below the rocking shaft 39 is swung left and right. Therefore, the durability of the supply hoses 41 and 42 can be improved. Further, the supply hose 41 wound in the shape of a letter toward the pair of left and right injection devices 4, 4 is connected to the inner ends of the supply hoses 41, 41 by a holder 43. The holder 43 is formed of a member having flexibility larger than the diameter of the supply hose 41, and the supply hose 41 is provided on the inner front surface or the inner rear surface of the blast injection recovery device B as the injection device 4 swings left and right. Even if the arrangement is such that the holder 43 comes into contact with the supply hose 41, the holder 43 comes in contact with the supply hose 41. The supply hoses 41 and 42 are preferably wound only once, and need not be wound a plurality of times.

  As shown in FIG. 9, in the intermediate part from the tip of the injection nozzle 1 to the floor surface Y, a part of the gas flow 2 and the particles 3 injected in the left and right end region C1 of the injection nozzle 1 that swings left and right. The shielding member S which shields is provided. The left-right swing speed of the injection nozzle 1 gradually decreases as it approaches the extreme end position Cm in the left-right end area C1, and is temporarily accelerated after being stopped. Therefore, the injection nozzle 1 fluctuates in the left-right end area C1. As the moving speed becomes slower, the wax material Fw on the floor surface Y is peeled off more than the central swinging region. However, by providing the shielding member S, the injection nozzle 1 can be placed at the most in the left and right end region C1. As the end position Cm approaches, the amount of collision of the gas flow 2 and the particles 3 with the floor surface Y can be gradually reduced, and the wax material Fw can be peeled uniformly over the entire left and right reciprocating rocking area CA. Can do.

Although the shielding member S in the present embodiment is provided behind the injection direction of the side-view injection nozzle 1, the same effect can be obtained even if it is arranged forward.
Further, the shielding member S in the left and right end region C1 of the injection nozzle 1 is inclined in plan view until the injection nozzle 1 swings to the predetermined position Cx, and until it swings from the predetermined position Cx to the extreme end position Cm. It is formed from the parallel part 56 in planar view parallel to the jet nozzle 1 swinging direction between them. FIG. 10 is a diagram showing changes in the injection range of the gas flow 2 and the particles 3 injected from the injection nozzle 1 toward the floor surface Y. In the state of FIG. 10A in which the injection range is not shielded, all the gas flow 2 and the particles 3 collide with the floor surface Y, but when the spray nozzle 1 swings, a part of the spray range is a shielding member. The state shown in FIG. 10B is blocked by S, and the amount of shielding in the spray range increases as the spray nozzle 1 approaches the extreme end position Cm by the inclined portion 55 of the shield member S. As shown in FIG. 10C, the shielding member S is formed with a parallel portion 56 in the same direction as the swinging direction of the injection nozzle 1 from the predetermined position Cx, and the injection range even if the injection nozzle 1 swings. The amount of shielding does not increase or decrease.

FIG. 11 shows waxes when the shielding member S is not used, when the shielding member S55 formed only by the inclined portion 55 is used, and when the shielding member S56 formed by the inclined portion 55 and the parallel portion 56 is used. The peeling state of the material Fw is shown.
When the shielding member S is not used, the wax material Fw peeling depth in the left and right end region C1 where the swinging speed of the spray nozzle 1 is slowed becomes deeper. However, if the shielding member S55 is used in the left and right end region C1, the peeling becomes uniform. The peeling operation in these wax peeling machines is generally performed while reciprocating as shown in FIG. 12, and when one row of peeling operations is completed, in the next row, the range of the wax material Fw peeled off in the front row Is partially polymerized and peeled off. At that time, when the shielding member S55 is used, if the peeling range is polymerized for the next row peeling operation, the wax material Fw is excessively peeled, but formed from the inclined portion 55 and the parallel portion 56. When the shielding member S56 is used, a slight shortage of peeling occurs in the left and right end regions C1 in the first row peeling operation, but if the peeling operation is performed by polymerizing a portion where the peeling is insufficient in the next row peeling operation. The uniform wax material Fw can be peeled over the entire peeled surface.

Next, the filter D of the vacuum device 17 will be described. The filter D has a cylindrical shape with an open top having a large surface area due to a corrugated cross section, and the inside of the vacuum chamber 20 and the granular tank 15 is maintained at a negative pressure by sucking the air inside the fan D with the fan 22. . If the filter D is clogged, the suction force is insufficient and the suction performance from the blast jet recovery device B is deteriorated. Therefore, it is necessary to replace the filter D periodically. However, clogging of the filter D is a frequently occurring problem, and it is difficult to remove the filter D and clean it every time it occurs.
In the vicinity of the fan 22 of the vacuum device 17 of the present embodiment, there is provided an ejection port 47 for ejecting compressed air for cleaning. The compressed air P is ejected from the inside of the filter D to remove dust adhering to the outer periphery of the filter D. Thus, the filter D performance can be recovered. In this filter D cleaning, when the cleaning switch 26 is turned ON, the filter backwash solenoid valve 50 is released, and a part of the air supplied from the compressor C can be intermittently injected into the filter D. Backwashing is performed at regular intervals. Or after a day of peeling work. The filter D is a cartridge type and can be easily replaced by opening the filter cover 53 at the rear of the vacuum device 17.

A diffusion plate 8 that diffuses the compressed air P ejected from the ejection port 47 is provided inside the filter D. The diffusion plate 8 is for diffusing the compressed air P inside the filter D, and is formed of a horizontally long plate. The diffuser plate 8 is provided in two upper and lower stages, and is arranged so that the upper and lower phases are different.
FIG. 13 shows the inside of the vacuum device 17, FIG. 13 (a) shows the state during the peeling work (in the vacuum by the fan 22), and FIG. 13 (b) shows the compressed air from the jet outlet 47. The state when P is ejected is shown. The compressed air P is ejected inward from above the filter D, but the backwashing of the filter D becomes insufficient only by ejecting. In particular, it is difficult to eliminate clogging at the top of the filter D where the compressed air P is not directly injected. In the present invention, the diffusion plate 8 made of a horizontally long plate is provided inside the filter D, and the compressed air P to be ejected is diffused to eliminate clogging at the top of the filter D. Is possible. The diffusing plate 8 is configured in two upper and lower stages, and the upper and lower phases are arranged 90 degrees different from each other, so that the filter D can be backwashed efficiently with a low cost and simple configuration.

The blast jet recovery apparatus B of the present invention is regulated so that the gas flow 2 is not jetted from the jet nozzle 1 when it is not in contact with the floor. A specific structure is provided with detection means UK such as a limit switch for detecting the up-and-down ascending / descending state of the blast injection recovery device B. When the detection means UK detects the rise of the blast injection recovery device B, the supply of the gas flow 2 is performed. Automatically shut off. Further, even when the blast switch 25 is turned on even when the blast injection recovery device B is raised at the start of the operation, the ON operation of the blast switch 25 is invalidated, and the gas flow 2 is discharged from the injection nozzle 1. It is regulated not to be injected.
Further, even when the blast injection recovery device B is lowered and grounded, the injection of the gas flow 2 is restricted unless the blast switch 25 is turned on after the travel switch 24 is turned on. This is because if the peeling operation is performed at a fixed position while the vehicle body 6 is stopped, the wax material Fw may be excessively peeled and the floor surface Y itself may be damaged.

  A vacuum recovery unit 5 is provided at the rear of the blast injection recovery device B, and the wax material Fw is removed while recovering the gas flow 2 and the particles 3 and the peeled wax particles W injected from the injection nozzle 1. Do. If the jetting from the jet nozzle 1 and the running are stopped simultaneously during running while performing the peeling operation, the particles 3 on the front floor surface Y in the blast box 54 and the separated wax particles W are not collected. In the present embodiment, when the injection from the injection nozzle 1 is stopped during forward traveling, the traveling is not stopped immediately, but after traveling a predetermined distance forward. It is controlled to automatically stop running. By doing so, the wax particles W remaining on the floor surface Y can be recovered while traveling forward a predetermined distance.

  However, simply by advancing a predetermined distance and then automatically stopping, the blast box 54 collides with the obstacle SH in an attempt to advance a predetermined distance even when an obstacle SH such as a wall or a step is ahead. Therefore, in the vicinity of the floor surface Y in front of the blast box 54, detection means SK for detecting a front obstacle SH is provided. When this detection means SK is operated, the forward traveling and the injection from the injection device 4 are stopped, and after a predetermined distance, the vehicle is controlled to return to the original reverse start position again. Thus, when there is an obstacle SH ahead, the wax particles W remaining on the floor surface Y in the blast box 54 are swept up by the front brush 45 and the elastic sheet 46 by moving backward once. The particles 3 and the wax particles W swept up can be recovered by advancing again.

  FIG. 9 is a control flow chart for regulating the gas flow 2 from the injection nozzle 1 and the resin bead J injection conditions in the floor wax peeling apparatus of this embodiment. In step S1, it is determined whether the power switch 23 is ON. If ON, the fan 22 of the vacuum device 17 is rotated to activate the vacuum recovery function. Next, when the travel switch 24 is turned ON, a determination of YES is made in step S2, the motor M mounted on the vehicle body 6 rotates according to the setting of the speed setting volume 27, and the vehicle body 6 starts traveling. From this state, if the blast switch 25 is ON in step S3, it is determined in step S4 whether or not the blast injection recovery device B is in contact with the floor, that is, whether or not the detection means UK is in an undetected state. If both step S3 and step S4 are determined as YES, injection of the gas flow 2 and the resin beads J from the injection device 4 is started. In the present embodiment, the injection is not started unless both step S2 and step S4 are determined to be YES, that is, the injection is started when the vehicle is running and the blast injection recovery device B is not in contact with the floor. However, as long as at least the scattering of the resin beads J can be prevented, the restriction requirement that the injection is not performed during traveling may be released.
