By the way, when winding up a water-absorbing mat that has absorbed rainwater or the like, the mat is squeezed and the water is discharged. This drainage floods the entrance where the water-absorbing mat has been laid. Moreover, when the rolled-up water-absorbing mat is transported, drainage water drips from the water-absorbing mat. As a result, it becomes necessary to wipe down the entrance and transportation route using a mop or the like.

Therefore, this specification discloses a water-absorbing mat carrier and a water-absorbing mat winding device that can suppress scattering of waste water during winding and transportation of the water-absorbing mat.

The water absorbent mat carrier disclosed herein includes a winding shaft, winding wheels, a pair of side water absorbing bodies, a tray, and transport wheels. The winding shaft is formed with an insertion slit along the axial direction into which the starting end of the water-absorbing mat is inserted. The winding wheels are provided at both axial ends of the winding shaft. The pair of side water absorbers are provided at both ends in the axial direction of the water absorbent mat wound around the winding shaft. The tray is radially spaced apart from the take-up shaft and extends along the axial direction of the take-up shaft. Transport wheels are provided on the tray.

When the water-absorbing mat is wound up, water is discharged from both axial ends of the water-absorbing mat being wound up. This waste water is absorbed by a pair of side water absorbers. Furthermore, during transportation, a tray is placed below the winding shaft and the water-absorbing mat wound on the winding shaft, so that the tray can receive drainage water dripping from the water-absorbing mat during transportation.

Further, in the above configuration, the side water absorbent body may be provided with an attachment/detachment slit so that it can be attached to and detached from the winding shaft.

According to the above configuration, it becomes possible to remove the side absorbent body that has absorbed wastewater from the water absorbent mat carrier. Further, by providing the attachment/detachment slit, it becomes possible to adjust the distance between the pair of side water absorbers to match the width of the water absorbent mat.

Further, the water-absorbing mat winding device disclosed in this specification includes the above-described water-absorbing mat carrier and water collector. The water collector includes a casing provided with an opening into which the terminal end of the water absorbing mat is inserted, and in which the terminal end water absorbent body is housed.

According to the above configuration, water discharged from the rear end of the water-absorbing mat during the winding process is absorbed into the water collector.

According to the water-absorbing mat carrier and the water-absorbing mat winding device disclosed in this specification, it is possible to suppress the scattering of waste water when winding up and transporting the water-absorbing mat.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, a water absorbent mat carrier and winding device according to an embodiment of the present invention will be explained using the drawings. The shape, material, number, and numerical values described below are examples for explanation, and can be changed as appropriate depending on the specifications of the water absorbent mat carrier and winding device. Further, in the following description, the same reference numerals are given to the same elements in all the drawings.

<Overall configuration>
The winding device for a water-absorbing mat according to the present embodiment includes a carrier 10 (see FIG. 1) and a water collector 50 (see FIG. 4). As shown in FIG. 5, which will be described later, the water absorbent mat 60 is wound up on the carrier 10. At this time, water discharged from both axial ends of the water absorbent mat 60 being wound up is absorbed by the pair of side water absorbers 34 and 35 (see FIGS. 2 and 3). Further, water discharged from the end of the water absorbent mat 60 during winding is absorbed by the water absorbent body 56 for the end of the water collector 50 (see FIGS. 5 and 6).

After winding up the water-absorbing mat 60, the water-absorbing mat 60 is transported to the carrier 10. During this transportation, the tray 20 (see FIGS. 7 and 8) of the carrier 10 is placed below the water absorption mat 60. With this arrangement, drainage water dripping from the water absorption mat 60 during transportation is collected in the tray 20.

<Water absorption mat>
FIG. 5 shows an example of a water-absorbing mat 60 that is an object to be rolled up by the winding device according to the present embodiment. The water-absorbing mat 60 includes a waterproof layer 62 as a base layer and a water-absorbing layer 64 as an upper layer. The base layer is composed of a sheet of water-impermeable material such as a rubber sheet. The water absorption layer 64 is made of, for example, pile fabric.

The water-absorbing mat 60 is laid, for example, on the entrance floor of a building. When water accumulates in the water absorbing layer 64 during rainy weather, etc., the mat 60 is replaced with a new water absorbing mat 60. During this exchange, the winding device according to this embodiment is used.

<Transporter>
1 to 3 illustrate a carrier 10, which is a part of the winding device according to the present embodiment. The carrier 10 for the water-absorbing mat 60 is capable of winding up and transporting the water-absorbing mat 60, as will be described later.

Note that FIG. 1 is a perspective view of the carrier 10 viewed from above. In FIG. 2, the carrier 10 is illustrated from below with the handle 38 on the left side of the page. Further, in FIG. 3, the carrier 10 is illustrated from below with the handle 38 on the right side of the drawing.

To clarify these angles, three orthogonal axes (X-axis, Y-axis, and Z-axis) are shown in FIGS. 1-3. The X-axis extends parallel to the axial direction of the winding shaft 32. The Y axis is perpendicular to the X axis, and the XY plane is parallel to the bottom wall 21 of the tray 20. Further, the Z axis is perpendicular to the X axis and the Y axis, and is parallel to the handle 44 of the carrier 10 (see FIG. 5).

1 to 3, the carrier 10 includes a tray 20, winding wheels 30, 31, a winding shaft 32, a pair of side water absorbers 34, 35, a handle 38, casters 39, and a removable handle 44. (See FIG. 5).

The winding shaft 32 is a rotating shaft member whose axial ends are rotatably supported (pivotally supported) by extension pieces 22A, 23A extending from the side walls 22, 23 of the tray 20. Insertion slits 32A are formed in the winding shaft 32 along the axial direction except for both axial ends. The insertion slit 32A is formed to penetrate the diameter of the winding shaft 32. As will be described later, a winding start end 60A (see FIG. 6) of the water absorbent mat 60 is inserted into the insertion slit 32A.

For example, when the water absorption mat 60 to be wound has a wide variety of sizes, the winding shaft 32 and the insertion slit 32A are arranged so that the width of the most of them exceeds the width of the mat, that is, the dimension perpendicular to the winding direction. Axial dimensions are determined.

A pair of winding wheels 30 and 31 are provided at both ends of the winding shaft 32 in the axial direction. The winding wheels 30 and 31 are configured to rotate together with the winding shaft 32. For example, the winding wheels 30 and 31 are ring-shaped, and both ends of the winding shaft 32 in the axial direction are inserted into the center hole and fixed to each other.

A pair of side water absorbers 34 and 35 are provided on the winding shaft 32. The side water absorbers 34 and 35 are provided closer to the axial center of the winding shaft 32 than the winding wheels 30 and 31 are. Further, the side water absorbers 34 and 35 are provided at both axial ends of the water absorbent mat 60 wound around the winding shaft 32. The side water absorbers 34 and 35 are made of sponge, for example.

For example, the side water absorbers 34 and 35 have a ring shape, and are provided with attachment/detachment slits 34A and 35A that penetrate in the radial direction. These attachment/detachment slits 34A, 35A enable the side water absorbers 34, 35 to be expanded from an O-shape to a C-shape, and can be attached to and detached from the winding shaft 32.

Utilizing this attachment/detachment function, the axial positions of the side water absorbers 34 and 35 on the winding shaft 32 can be adjusted. For example, as shown in FIGS. 5 and 6, with the starting end 60A of the water absorbent mat 60 inserted into the insertion slit 32A, the side water absorbers 34 and 35 are arranged at both ends of the water absorbent mat 60 in the width direction. The axial positions of the water absorbers 34 and 35 on the winding shaft 32 are adjusted.

As will be described later, the side water absorbers 34 and 35 are provided to absorb water discharged from both axial ends of the water absorbent mat 60 being wound up. By performing the position adjustment as described above, drainage from the water absorbing mat 60 can be reliably absorbed into the side water absorbing bodies 34 and 35.

Referring to FIGS. 1-3, tray 20 is radially spaced apart from take-up shaft 32. Referring to FIGS. Furthermore, the tray 20 extends along the axial direction of the winding shaft 32.

The tray 20 has a box shape open to the winding shaft 32, and includes, for example, a rectangular bottom wall 21 and side walls 22, 23, 24, and 25 provided on each of the four sides of the bottom wall. The distance between the side walls 24, 25 is, for example, greater than the diameter of the winding wheels 30, 31. Further, the separation distance between the side walls 22 and 23 is formed to be equal to or exceed the axial dimension of the winding shaft 32, for example.

The side walls 22 and 23 facing each other along the axial direction of the winding shaft 32 are provided with extension pieces 22A and 23A extending toward the winding shaft 32 side. A winding shaft 32 and winding wheels 30, 31 are pivotally supported on the extension pieces 22A, 23A. That is, the winding shaft 32 and the winding wheels 30, 31 (in addition to these, the side water absorbers 34, 35) rotate relative to the tray 20.

Note that a rotation direction control mechanism (not shown) may be provided between the tray 20 and the winding wheels 30, 31. This rotational direction control mechanism includes a locking mechanism that stops the rotation of the winding wheels 30 and 31 relative to the tray 20, and a ratchet and mechanism that can restrict the rotational direction of the winding wheels 30 and 31 relative to the tray 20. Further, the ratchet mechanism may be provided with a switching lever that limits the direction of rotation to either forward or reverse.

Furthermore, a handle 38 is provided on the extension piece 22A of the side wall 22. On the other hand, the side wall 23 is provided with casters 39 which are wheels for transportation.

Further referring to FIGS. 1 and 5, a support ring 40 is provided on the exposed surface of the bottom wall 21 of the tray 20. As shown in FIG. For example, a support ring 40 is provided at the center portion of the bottom wall 21 in the longitudinal and lateral directions. The support ring 40 includes an insertion hole 42 whose axis is perpendicular to the exposed surface of the bottom wall 21 .

A removable handle 44 is inserted into the insertion hole 42. The support ring 40 and handle 44 may be provided with a retaining mechanism. For example, an L-shaped groove (not shown) is formed on the inner peripheral surface of the support ring 40. Furthermore, a guide protrusion (not shown) that projects in the radial direction is provided at the tip (lower end) of the handle 44.

The handle 44 is inserted into the support ring 40 so that the guide projection is inserted into the groove. Further, by rotating the handle 44 with respect to the support ring 40, the handle 44 is prevented from coming off from the support ring 40.

<Water collector>
FIG. 4 illustrates a water collector 50 that is part of the winding device according to this embodiment. The water collector 50 includes a casing 52 and an end water absorber 56. The casing 52 is a box body provided with an opening 52A, and its longitudinal dimension is, for example, equivalent to the axial dimension of the winding shaft 32 of the carrier 10.

A handle 54 is provided on the casing 52 so that it can be carried by an operator. A water absorbent body 56 for termination is housed in the casing 52 . The end water absorbent body 56 is made of, for example, a sponge.

<Winding process>
5 and 6 illustrate a winding process of the water absorbing mat 60 using the winding device according to this embodiment. During this winding process, the handle 44 is inserted into the support ring 40 of the tray 20. Thereafter, the starting end 60A of the water-absorbing mat 60 laid on the entrance floor of the building or the like is inserted into the insertion slit 32A of the winding shaft 32. The starting end 60A of the water-absorbing mat 60 is, for example, one of the opposing short sides of the rectangular water-absorbing mat 60.

Next, the positions of the side water absorbers 34 and 35 (see FIGS. 2 and 3) are adjusted so that they are arranged at both ends of the water absorbent mat 60 in the axial direction. For example, the side water absorbers 34 and 35, which have been opened in a C-shape by the attachment/detachment slits 34A and 35A, are moved in the axial direction of the winding shaft 32.

Furthermore, the rear end 60B of the water absorption mat 60 is inserted into the opening 52A of the water collector 50. The rear end 60B of the water-absorbing mat 60 is, for example, the other side of the rectangular water-absorbing mat 60 that faces the starting end among the opposing short sides.

As illustrated in FIG. 6, the operator moves the carrier 10 toward the water collector 50 while holding the handle 44 and tilting the carrier 10 forward. During the movement, the winding wheels 30 and 31 and the winding shaft 32 rotate, and the water-absorbing mat 60 is accordingly wound around the winding shaft 32.

During this winding process, the water absorbed in the water absorption layer 64 of the water absorption mat 60 is drained. More specifically, water is discharged from both axial ends of the water absorbing mat 60 wound around the winding shaft 32.

Here, as described above, a pair of side water absorbers 34 and 35 are arranged at both axial ends of the wound water absorbent mat 60. Therefore, water discharged from the water-absorbing mat 60 being wound is absorbed by the side water-absorbing bodies 34, 35.

Furthermore, by winding up the water-absorbing mat 60, water in the water-absorbing layer 64 (see FIG. 5) is moved (pushed) toward the rear end 60B. The water discharged from the rear end of the water absorbing mat 60 is absorbed by the end water absorbing body 56 in the water collector 50, thereby suppressing drainage to the surrounding area.

After winding up the water absorbing mat 60, for example, the side water absorbing bodies 34, 35 are removed from the winding shaft 32. Further, the water absorbing body 56 for the end of the water collector 50 is also removed from the casing 52. These water absorbers discharge waste water through a drain port (not shown) or the like.

<Transportation process>
7 and 8 illustrate a process of transporting the water-absorbing mat 60 by the transporter 10 according to the present embodiment. For example, a hook-and-loop bind belt 70 is wound around the water-absorbing mat 60 and the tray 20 that have been completely wound up. Further, the rotation of the winding wheels 30 and 31 is stopped by a lock mechanism (not shown).

Furthermore, upon transportation, the handle 44 (see FIG. 6) is removed from the carrier 10. Further, the tray 20 is positioned below the water absorption mat 60 and the winding shaft 32. When the operator lifts the handle 38, the casters 39, which are transportation wheels, touch the ground. In this state, the carrier 10 and the water absorption mat 60 are transported.

During this transportation process, the drain water dripping from the water absorption mat 60 is caught by the tray 20. For example, in order to accommodate a sufficient amount of drainage, a portion of the tray 20 that is located relatively lower during transportation may be configured to be deep. For example, referring to FIG. 2, the side walls 24 and 25 may be formed so that the side on the caster 39 side is higher than the side on the handle 38 side. Further, the side wall 23 may be formed to be higher than the opposing side wall 22.

When the water-absorbing mat 60 is transported to a collection point, such as in front of a collection vehicle, a locking mechanism (not shown) is released, and the winding shaft 32 becomes free (or can rotate in the opposite direction to the winding direction). The water absorption mat 60 is pulled out.

As described above, according to the transporter 10 for the water-absorbing mat 60 according to the present embodiment and the winding device including the water collector 50, when transporting the water-containing water-absorbing mat 60 from the installation point to the collection point, It is possible to suppress the scattering of wastewater on the transportation route from the installation point to the collection point.
