DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] An embodiment of a plate body regulating mechanism for a winding device according to the present invention will be described with reference to the drawings. In the following description, the arrows in each drawing indicate F, B, R, L, U, and D, respectively.

[0017] As shown in FIGS. 1 to 4, the unwinding and winding device 10 generally comprises a plate body 20, a holder 40, a unwinding and winding shaft 80, and a motor M1 as a driving means.

[0018] In this embodiment, the plate body 20 is composed of one plate 21. The plate 21 is made of metal, and as shown in Figs. 1 to 4, is in the form of a long thin plate, and its cross section in the short direction is formed in an arc shape with a concave upper side, and has the uprightness to allow linear movement and flexibility to allow for unwinding and winding. The plate 21 is a repurposed measuring tape part of a convex (steel tape measure). In addition, due to the flexibility of the plate 21, when it is bent in the longitudinal direction, it changes from an arc shape to a straight line in the short direction, and when it is wound up, it becomes a tightly packed spiral shape, making it compact.

[0019] The holder 40 is made of metal, and includes a first storage section 50, a second storage section 60, and a lower storage section 70, as shown in FIGS.

[0020] The first storage section 50 has a pair of side walls 51, 51, a connecting section 52, and a direction regulating section 53, and is formed in a cylindrical shape with both ends closed, separating the inside from the outside, and is capable of storing the plate 21.

[0021] The side walls 51 are formed in a disk shape and are disposed so as to face each other in the left-right direction.

[0022] The connecting portion 52 is formed in a cylindrical shape, and its left and right ends are connected to a pair of side walls 51, 51. An opening 52a having a width allowing the plate 21 to pass through is provided at the bottom of the connecting portion 52.

[0023] The direction control section 53 is formed in a rectangular tube shape that is long in the left-right direction and short in the up-down direction, and is connected to the opening 52a of the connecting section 52. The direction control section 53 allows the plate 21 to move in and out in the front-to-back direction, and is also capable of controlling the direction in which the plate 21 is unrolled and wound up.

[0024] In this embodiment, the direction restricting section 53 includes a guide section 54 formed such that a lower wall extends further rearward than an upper wall. The guide section 54 is in contact with the plate 21 and is capable of guiding the plate 21 from a region surrounded by the pair of side walls 51, 51 and the connecting section 52 toward the direction restricting section 53. In detail, the guide section 54 is formed such that, when viewed from the left-right direction, it extends obliquely upward from the front to the rear and its rear end portion extends obliquely downward, and its rear end portion is connected to a rear wall 62 of a second storage section 60 described later.

[0025] The second storage section 60 has a front wall 61, a rear wall 62, and side walls 63, 63, and is arranged with a space outside the first storage section 50, and is formed so that its lower end side (one end side) communicates with the first storage section 50 and its upper end side (the other end side) is closed.

[0026] The lower storage section 70 has a rear wall 71, a bottom wall 72, and side walls 73, 73, and is arranged below the first storage section 50 and below and behind the second storage section 60, with a space between the first storage section 50 and the second storage section 60, and is capable of storing a motor M1, a chain 84, a power supply (not shown), a controller unit, etc. (described later).

[0027] The payout / winding shaft 80 includes a shaft member 81 and a bobbin 85, as shown in FIGS.

[0028] The shaft member 81 is made of metal and is formed in a cylindrical shape. The bobbin 85 is also made of metal and includes a cylindrical shaft portion 86 and flange portions 87, 87 extending in an annular shape from the ends of the shaft portion 86 in the axial direction.

[0029] In this embodiment, the payout / winding shaft 80 is integrally formed with the shaft member 81 by fitting a shaft portion 86 of a bobbin 85 onto the outer periphery of the shaft member 81 .

[0030] The unwinding and winding shaft 80 is attached via a bearing 82, with the left and right ends of the shaft member 81 inserted into the side walls 51, 51 of the first storage section 50, respectively, and is rotatable with the left and right directions as the rotation axis relative to the pair of side walls 51, 51.

[0031] A driven gear 83 is attached to the right end of the shaft member 81 of the payout / winding shaft 80 .

[0032] The motor M1 is an existing motor, and as shown in Figures 1 to 4, is disposed at the right rear of the lower storage section 70. A drive gear M1b is attached to a rotating shaft M1a of the motor M1.

[0033] A chain 84 is stretched between the drive gear M1b and the driven gear 83, so that the drive force of the motor M1 can be transmitted to the unwinding / winding shaft 80.

[0034] Plate 21 is fixed to shaft portion 86 of bobbin 85 of unwinding / winding shaft 80 and wound around it so as to be able to be unwound. In the state shown in Fig. 3, most of plate 21 is disposed within first storage portion 50, and with plate 21 inserted through opening 52a and direction regulating portion 53, the tip portion is disposed so as to be exposed.

[0035] The unwinding and winding device 10 is controlled by a controller unit (not shown) that receives power from an external power source (not shown) and has control, input, output, communication, and power connection functions. The controller unit (not shown) is connected to the motor M1, and causes the plate 21 to be unwound from the unwinding and winding device 10 and then wound up.

[0036] The main part of the present invention will now be described.

[0037] The unwinding / winding device 10 is provided with a plate body regulating mechanism 100 for regulating the wound plate 21 so that it does not loosen from the unwinding / winding shaft 80 and spread away from the unwinding / winding shaft 80 during unwinding / winding.

[0038] In this embodiment, the plate body regulating mechanism 100 includes a regulating member 110, a coil spring 120 serving as a biasing member, and a direction changing portion 130, as shown in FIGS.

[0039] The restricting member 110 is made of a synthetic resin that is not easily stretched, has a sheet shape, and is formed so as to be narrower than the width of the plate 21 in the left-right direction.

[0040] The coil spring 120 is an existing coil spring, and has an upper end fixed to the upper end of the second storage section 60 and a lower end connected to the other end of the regulating member 110, which will be described later. In this embodiment, three coil springs 120 are provided.

[0041] The direction changer 130 is made of metal, formed into a cylindrical shape, has a surface treatment applied to make the plate 21 easier to slide on, and is disposed at the boundary between the first storage section 50 and the lower side (one end side) of the second storage section 60. The length of the direction changer 130 in the left-right direction is shorter than the inside length of the flange sections 87, 87 of the bobbin 85, and is disposed so as not to come into contact with the flange sections 87, 87. The direction changer 130 changes the direction of the regulating member 110.

[0042] One end of the regulating member 110 is fixed to the periphery of the direction regulating portion 53 of the connecting portion 52 , and the other end is fixed to the upper end portion of the second storage portion 60 via a coil spring 120 .

[0043] From the above, it can be said that one end of the regulating member 110 is fixed around the periphery of the direction regulating portion 53, and the other end is fixed at a location different from the one end at the other end side of the second storage portion 60.

[0044] The regulating member 110 is disposed so as to rise diagonally upward to the left from the periphery of the direction regulating portion 53, and is disposed so as to be in contact with the outer peripheral surface 21a of the plate 21 wound around the unwinding winding shaft 80. At this time, the regulating member 110 is disposed so as not to be in contact with the outer peripheral surface 21a on the lower side of the plate 21, and is disposed so as to be curved while coming into contact with the outer peripheral surface of the direction changing portion 130, makes a U-turn, and faces upward, and is connected to the lower end of the coil spring 120.

[0045] From the above, it can be said that, when viewed from the axial direction of the unwinding / winding shaft 80, the regulating member 110 is in contact with the outer circumferential surface 21a of the plate 21 wound around the unwinding / winding shaft 80 except for at least a portion, and is disposed so as to form an opening portion that is open on one side and closed on the other side, and the plate 21 is unwinded / wound through the opening portion of the regulating member 110. It can also be said that the plate 21 is able to pass between the fixed portion on one end side of the regulating member 110 and the direction changing portion 130.

[0046] The function and operation of the plate body regulating mechanism 100 will be described. In the state shown in Figs. 1 to 3, most of the plate 21 is stored in the first storage section 50, and a portion is exposed. The regulating member 110 contacts the plate 21 except for a lower portion of the outer circumferential surface 21a of the plate 21, and is folded back upward at the direction changing section 130.

[0047] In this state, the outer diameter of the plate 21 wound around the unwinding / winding shaft 80 is at its maximum, the regulating member 110 is pulled out of the second storage section 60, and the coil spring 120 is in an extended state.

[0048] The plate body restriction mechanism 100 restricts the plate 21 by the biasing force (pulling force) of the coil spring 120 so that the plate 21 does not loosen from the unwinding / winding shaft 80 and spread away from the unwinding / winding shaft 80 .

[0049] FIG. 4 shows the state in which the plate 21 is fully unwound. At this time, the outer diameter of the plate 21 wound around the unwound winding shaft 80 is at its minimum, the coil spring 120 is compressed, and the regulating member 110 is pulled back into the second storage section 60.

[0050] In the plate body regulating mechanism 100, the regulating member 110 is pulled out of the second storage section 60 when the outer diameter of the plate 21 is large, and is pulled back into the second storage section 60 when the outer diameter of the plate 21 is small. The regulating member 110 always presses the outer peripheral surface 21a of the plate 21 due to the elastic deformation of the coil spring 120, and is capable of responding to changes in the outer diameter caused by the unwinding and winding of the plate 21 wound around the unwinding and winding shaft 80.

[0051] Here, the configuration of the plate body regulating mechanism 100 described above that corresponds to the claims and the effects thereof will be described.

[0052] The plate body regulating mechanism 100 is A plate 21 as a plate body 20 having a long thin plate shape, at least a part of a cross section in a short direction is formed by bending and / or curving, and having an uprightness that allows linear movement and a flexibility that allows it to be unwound and wound up; A holder 40 including a pair of side walls 51, 51 and a connecting portion 52 connecting the pair of side walls 51, 51, and a direction restricting portion 53 connected to the connecting portion 52, allowing the plate 21 to move in and out and restricting the payout / winding direction of the plate body; a winding shaft 80 around which the plate 21 is fixed and wound, the winding shaft 80 being rotatably disposed relative to the pair of side walls 51, 51; A motor M1 as a driving means connected to the unwinding / winding shaft 80 to enable the plate 21 to be unwound and wound; The plate 21 is held by the holder 40 so as to be capable of being unwound and wound, The reel includes a restricting member 110 that is formed in a sheet shape and is biased by a coil spring 120 as a biasing member to restrict the plate 21 from spreading away from the unwinding / winding shaft 80; The regulating member 110 has one end fixed around the periphery of the direction regulating portion 53 and the other end fixed to the holder 40 at a location different from the one end, and is arranged so that, when viewed from the axial direction of the unwinding / winding shaft 80, the regulating member 110 comes into contact with the outer circumferential surface 21a of the plate 21 wound around the unwinding / winding shaft 80 except for at least a portion, and is arranged so that an opening portion that is open on one side is formed and that the other side is closed. The plate 21 passes through the opening of the regulating member 110 and is unwound and wound up.

[0053] According to this, the plate body regulating mechanism 100 allows the plate 21 to be unwound and wound without interference between the regulating member 110 and the plate 21, and can regulate the plate 21 from spreading away from the unwound and wound shaft 80 when the plate 21 is unwound and wound.

[0054] In addition, the plate body regulating mechanism 100 is The holder 40 is a first storage section 50 including a pair of side walls 51, a connecting section 52, and a direction restricting section 53, the first storage section 50 being formed in a cylindrical shape with both ends closed, separating the inside from the outside, and storing the plate 21; a second storage section 60 that is disposed outside the first storage section 50, communicates with the first storage section 50 at one end side, and has a closed other end side; Equipped with A direction change portion 130 for changing the direction of the regulating member 110 is provided at the boundary between the first storage portion 50 and one end side of the second storage portion 60. The regulating member 110 has one end fixed to the periphery of the direction regulating portion 53 and the other end fixed to the other end of the second storage portion 60. The plate 21 can pass between a fixed portion on one end side of the regulating member 110 and the direction changing portion 130 .

[0055] According to this, the plate body regulating mechanism 100 can be arranged by folding back the regulating member 110 at the direction changing portion 130, so that the device can be made compact.

[0056] [About modified examples] The plate regulating mechanism of the payout winding device of the present invention is not limited to the above-mentioned embodiment, and various design modifications are possible without departing from the gist of the invention shown in the above-mentioned embodiment.

[0057] For example, although the regulating member 110 is in the form of a sheet, it may be in the form of a line or a strip, including a convex tape like the plate 21.

[0058] Furthermore, the restricting member 110 is made of synthetic resin that is difficult to stretch, but it may be made of rubber, metal, or other material that is difficult to stretch.

[0059] The restricting member 110 may be formed in a line, band, or sheet shape and may be elastically deformable. In this case, the other end of the restricting member 110 may be directly fixed to any location in the first storage section 50 without using the coil spring 120, and the second storage section 60 may be eliminated.

[0060] Furthermore, although the coil spring 120 is used as the biasing member, a member other than the coil spring 120 may be used as long as it can accommodate changes in the outer diameter caused by unwinding and winding the plate 21 .

[0061] Further, although the unwinding / winding shaft 80 is constituted by the shaft member 81 and the bobbin 85, it may be constituted by the shaft member 81 only.

[0062] Further, the driving and control method of the unwinding and winding device 10 in the present invention is not limited to the above-mentioned method, and can be changed appropriately according to the usage mode, for example, to be driven manually and / or by a motor.

[0063] In the present invention, the material of the plate 21 constituting the plate body 20 can be any material other than metal, so long as it has the uprightness to allow linear movement and the flexibility to allow reeling and winding.

[0064] Further, the direction changing portion 130 may be made of other members such as a roller, a pulley, etc., as long as the direction changing portion 130 can change the direction of the regulating member 110 .

[0065] Moreover, a configuration without the direction changing section 130 is also possible.

[0066] Moreover, the holder 40 may be configured without the connecting portion 52 .

[0067] In addition, the direction regulating portion 53 can be connected to the pair of side walls 51, 51, or to the pair of side walls 51, 51 and the connecting portion 52.

[0068] Further, in the above embodiment, one end side of the regulating member 110 is fixed around the direction regulating portion 53, but it is also possible to fix it at the direction regulating portion 53.

[0069] In addition, the plate body regulating mechanism 100 can be applied to the snow removal device of Patent Application No. 2023-052464, previously filed by the applicant.

[0070] In addition, the plate body regulating mechanism 100 can be applied to a pay-out / wind-up device for paying-out and winding up plate bodies for other purposes, in addition to the snow removal device of the above-mentioned Patent Application No. 2023-052464.

[0071] In addition, the sliding bodies described as the respective embodiments and modified examples of Patent Application No. 2023-052464 previously filed by the applicant can be used for the plate body 20.

[0072] Modified examples of the regulating member will be described with reference to Figures 5(a), 6, and 7. In the following description, the same reference numerals are used for configurations corresponding to those in the above embodiment, and the description thereof will be omitted in whole or in part.

[0073] The regulating member 110A includes two elastically deformable metallic linear members 111A, a metallic shaft 112A, and a metallic roller 113A.

[0074] A shaft 112A is suspended between two linear members 111A, and a roller 113A is attached to the outside of the shaft 112A so as to be rotatable relative to the shaft 112A.

[0075] More specifically, a hole 112Aa is formed in the shaft 112A so as to be perpendicular to the axis, the linear member 111A is inserted through the hole, and a stopper 114A is attached near the hole 112Aa to fix the shaft 112A.

[0076] The regulating member 110A has one end fixed to the periphery of the direction regulating portion 53, and the other end directly fixed to the first storage portion 50. In this modification, the second storage portion 60 can be eliminated.

[0077] Similarly to the regulating member 110, the regulating member 110A is in contact with the outer peripheral surface 21a of the plate 21 wound around the reel-out and winding shaft 80 except for at least a portion when viewed from the axial direction of the reel-out and winding shaft 80, and is disposed so as to form an opening portion that is open on one side and close on the other side, and the plate 21 is reeled out and wound through the opening portion of the regulating member 110A. The regulating member 110A is disposed in the center of the plate 21 in the left-right direction (width direction) as shown in FIG. 6.

[0078] The regulating member 110A reduces frictional resistance with the outer circumferential surface 21a of the plate 21 by contacting the outer circumferential surface 21a of the plate 21 with the rotatable rollers 113A.

[0079] 3 and 4, one end of the linear member 111A is fixed around the direction restricting portion 53, and the other end is connected to a coil spring 120 as a biasing member, so that the restricting member 110A is biased toward the outer peripheral surface 21a of the plate 21.

[0080] Also, the stopper 114A may be eliminated, and the shaft 112A may be made movable along the linear member 111A.

[0081] Alternatively, the rollers 113A may be omitted, and the outer circumferential surface of the shaft 112A may be brought into contact with the outer circumferential surface 21a of the plate 21. In this case, the shaft 112A serves as a contact member that comes into contact with the plate body 20.

[0082] Also, it is possible to fix the shaft 112A to the linear member 111A without providing the hole 112Aa in the shaft 112A.

[0083] 5(b), the regulating member 110A may be configured such that three linear members 111A are used, a shaft 112A is spanned between the linear members 111A, and rollers 113A are attached to the outside of the shaft 112A in two rows in the width direction of the regulating member 110A. Furthermore, it is also possible to use three or more linear members 111A and attach two or more rows of rollers 113A in the width direction of the regulating member 110A.

[0084] Moreover, the shaft 112A and the roller 113A may be made of synthetic resin.

[0085] Also, as shown in FIG. 8, the restricting member can be formed in a net shape.

[0086] In FIG. 8(a), the regulating member 110B is made of a metal material that is not easily stretched, and includes two linear members 111B and a mesh body 112B formed in a lattice shape and spanning between the linear members 111B.

[0087] In this case, one end of the regulating member 110B is fixed around the direction regulating portion 53, and the other end is connected to a coil spring 120 serving as a biasing member, and is biased toward the outer peripheral surface 21a of the plate 21.

[0088] In FIG. 8(b), the regulating member 110C itself is made of synthetic resin or the like and is elastically deformable. Unlike FIG. 8(a), the regulating member 110C is configured to have only a mesh body 112C and no members corresponding to the two linear members 111B at both ends in the short direction.

[0089] In this case, the regulating member 110C may be fixed at one end to the periphery of the direction regulating portion 53, and the other end may be fixed directly to the first storage portion 50.

[0090] The width, number of lattices, and shape of the mesh members 112B and 112C can be appropriately changed depending on the manner of use.

[0091] It is also possible to form it into a shape as shown in FIG.

[0092] In FIG. 9(a), the regulating member 110D is formed from a metal member that is difficult to stretch, and has two linear members 111D and a plurality of connecting bodies 112D formed in a ring shape that are spanned between the linear members 111D, with one end side fixed around the periphery of the direction regulating portion 53 and the other end side connected to a coil spring 120 as a biasing member, and biased toward the outer peripheral surface 21a of the plate 21.

[0093] In FIG. 9(b), the regulating member 110E itself is made of synthetic resin or the like so as to be elastically deformable, and unlike FIG. 9(a), it is configured with only a plurality of connecting bodies 112E formed in a ring shape, and no members corresponding to the two linear members 111D at both ends in the short direction.

[0094] In this case, the regulating member 110E may be fixed at one end to the periphery of the direction regulating portion 53, and the other end may be fixed directly to the first storage portion 50.

[0095] In addition, the connectors 112D and 112E may be arranged in not only one row but also two or more rows in the width direction of the connectors 112D and 112E.

[0096] Furthermore, connector 112D and connector 112E may have a shape other than a ring, such as a polygonal ring or an elliptical ring.

[0097] Configurations such as regulating member 110A, regulating member 110B, regulating member 110C, regulating member 110D, and regulating member 110E can also regulate the plate body 20 from spreading away from the unwinding / winding shaft 80 when the plate body 20 is being unwound.

[0098] The restricting member may also be formed in a ladder shape.

[0099] Here, the "contact portion" in claim 3 refers to a portion of the regulating member 110, the regulating member 110A, the regulating member 110B, the regulating member 110C, the regulating member 110D, and the regulating member 110E that comes into contact with the plate 20.
