Description
本発明は床材剥離装置に関するものである。 The present invention relates to a floor material peeling device.
従来より、ビルなど建築物のコンクリート等の床下地上に貼り付けられた塩化ビニル製タイル、Ｐタイル、クッションフロアー等の床材を張り替える際には、古い床材を剥離する必要がある。このような剥離作業に使用する床材剥離装置として、従来より、種々の形態の装置が提案されている。
2. Description of the Related Art Conventionally, when replacing floor materials such as vinyl chloride tiles, P tiles, and cushion floors that are pasted on a floor substrate such as concrete of a building or the like, it is necessary to remove old floor materials. As a floor material peeling device used for such peeling work, various types of devices have been conventionally proposed.
近年、電車などの車両の通路に貼られた長尺シートの張り替えやオフィスビルの一室やマンションの通路の床の張り替えなど、狭い空間での床材剥離作業が増えており、小回りが効き取り扱いし易く、床材を剥離する力が強い床材剥離装置が要求されている。 In recent years, floor material peeling work has been increasing in narrow spaces, such as re-installing long sheets attached to the passages of vehicles such as trains and re-filling floors of aisles in office buildings and condominiums. There is a demand for a floor material peeling device that is easy to do and has a strong force for peeling the floor material.
このような要求に対し、特許第５２６３７４６号の装置は小回りが効き取り扱いし易いが、床材を剥離する力は弱いものである。 In response to such a demand, the device of Japanese Patent No. 5263746 is effective in providing a small turning and is easy to handle, but has a weak force for peeling a floor material.
特許第２６０８８２９号の装置は床材を剥離する力が強く、プーリーに掛け渡されたクローラにより前進や後退や旋回ができ、作業者に大きな力を強いることは少ないが、床材離用刃板から手押しハンドルに至るまでの装置の全長が長いので、装置を旋回させる際に広い旋回半径を必要とするものである。 The device of Japanese Patent No. 2608829 has a strong force for peeling off the floor material, and the crawler that is hung on the pulley allows it to move forward, backward, and swivel. Since the entire length of the device from the handle to the push handle is long, a large turning radius is required when turning the device.
また、特開２００２−１８８２９８号広報の装置は、床材を剥離する力は十分あるが、装置を旋回させる場合には作業者に苦労を強いるものである。 Further, the device disclosed in Japanese Patent Laid-Open No. 2002-188298 has a sufficient force for peeling off the floor material, but when turning the device, it puts a hard work on the operator.
図３を用いて特開２００２−１８８２９８号広報の装置を旋回させる方法を説明する。図３（ａ）は装置を旋回させる為に、床材剥離用刃板を床から浮かせた状態である。装置の上面には重りが取り付けてあり、装置の自重は約１２０Ｋｇあるので、作業者は自身の上半身の体重を手押しハンドルの先端にかけて装置を傾ける。この時、装置が後方に傾くので、手押しハンドルを握っている作業者の身体は、装置の後方へ離れる。作業者はこのような姿勢で、床材剥離用刃板が床につかない様に保ちながら、自分自身が車輪を中心に回りながら装置を旋回させる。 A method of turning the device disclosed in Japanese Patent Laid-Open No. 2002-188298 will be described with reference to FIG. FIG. 3A shows a state in which the floor material separating blade plate is lifted from the floor in order to rotate the apparatus. Since a weight is attached to the upper surface of the apparatus and the weight of the apparatus is about 120 kg, the operator leans the weight of the upper half of the body of the operator to the tip of the hand push handle and tilts the apparatus. At this time, since the device tilts rearward, the body of the worker who holds the push handle separates to the rear of the device. In such a posture, the worker turns the device while rotating around the wheel by himself while keeping the floor material peeling blade plate so as not to touch the floor.
図３（ｂ）は、装置を時計回りに１８０°旋回させた時の軌跡を示している。点Ｏは旋回の中心であり、左右の車輪の中間点である。円弧Ａ１からＡ２は床材剥離刃板の移動軌跡であり、点Ｏから円弧Ａ１からＡ２までが床材剥離装置の回転半径である。円弧Ｂ１からＢ２は作業者の腰の移動軌跡であり、点Ｏから円弧Ｂ１からＢ２までが作業者の回転半径である。Ｗは装置の回転半径と作業者の回転半径の和であり、特開２００２−１８８２９８号広報の装置ではＷは約１４００ｍｍであり、装置を旋回させる際には少なくとも１４００ｍｍの床幅を必要とする。 FIG. 3B shows a locus when the device is turned clockwise by 180°. Point O is the center of turning and is the midpoint between the left and right wheels. The arcs A1 to A2 are the movement trajectories of the floor material peeling blade plate, and the arcs A1 to A2 from the point O are the turning radii of the floor material peeling device. The arcs B1 to B2 are the loci of movements of the waist of the worker, and the circles B1 to B2 from the point O are the turning radii of the worker. W is the sum of the radius of gyration of the device and the radius of gyration of the operator. In the device disclosed in Japanese Patent Laid-Open No. 2002-188298, W is about 1400 mm, and a floor width of at least 1400 mm is required to rotate the device. ..
また、従来の装置では、床材剥離用刃板を交換するなど、メンテナンスの際には、装置を横に倒したり、ひっくり返したりする必要があり、この動作は作業者にとっては負担となるものである。 In addition, in the conventional device, it is necessary to tilt the device sideways or turn it over for maintenance such as exchanging the floor material peeling blade plate, and this operation is a burden to the operator. Is.
以上の様に、従来技術の床材剥離装置は、装置を旋回させる際に、広い床幅を必要とするので、作業現場での装置の取り回しが困難であるという課題と、装置を旋回させる時やメンテナンスの際に作業者に大きな力を強いるという課題を有しており、床材を剥離する力が強くて小回りが効いて取り扱いし易い床材剥離装置はまだ提案されていない。
As described above, the conventional floor material peeling device requires a wide floor width when the device is turned, so that it is difficult to handle the device at the work site and when the device is turned. There is a problem that the operator is required to exert a large force during maintenance, and a floor material peeling device that has a strong force for peeling the floor material, is effective for a small turn, and is easy to handle has not yet been proposed.

In the floor material peeling device (1), since the turning member (13) is configured to contact the floor in front of the center of gravity of the floor material peeling device (1) in the front-rear direction, the floor material peeling blade plate (11). ) Separates from the floor and is in a state of being grounded to the floor by the wheels (12) and the turning member (13). In the floor material peeling device (1) of the present invention, the floor material peeling blade plate (11) is separated from the floor by about 50 mm.
続いて、本発明の床材剥離装置（１）を用いて床材剥離作業を行っている状態を説明する。運転スイッチ（５）をＯＮしてモーター（７）を回転させると、床材剥離用刃板（１１）は前後に摺動し、車輪（１２）は前進方向に駆動するが、床材が剥がれにくい所もあるので、作業者は手押しハンドル（２８）を前方へ押して力を加えながら、蛇行しないように修正しながら床材を剥がしていく。 Next, a state where floor material peeling work is performed using the floor material peeling apparatus (1) of the present invention will be described. When the operation switch (5) is turned ON and the motor (7) is rotated, the floor material peeling blade plate (11) slides back and forth, and the wheels (12) drive in the forward direction, but the floor material peels off. Since there are difficult places, the worker pushes the hand handle (28) forward to apply force, and removes the floor material while making corrections so as not to meander.
また、図１（ａ）の状態では旋回部材（１３）は固定されていないので、アーム（１４）の係止受部（１６）を設けている側の重量を重り（図示せず）を設けるなど重くしておき、旋回部材（１３）が接地しないようにしている。 Further, since the turning member (13) is not fixed in the state of FIG. 1(a), the weight of the side of the arm (14) on which the lock receiving portion (16) is provided is weighted (not shown). For example, the turning member (13) is prevented from coming into contact with the ground.
また、前進を一時停止させたり、進め方向を変えたい場合は、作業者はクラッチレバー（４）を握って車輪（１２）の回転を止める。 When the operator wants to stop the forward movement or change the forward direction, the operator holds the clutch lever (4) and stops the rotation of the wheels (12).
続いて、本発明の床材剥離装置（１）を旋回させる方法を説明する。図２（ａ）は、旋回部材（１３）が床に接地されて固定され、車輪（１２）と旋回部材（１３）が床に接地して床材剥離用刃板（１１）だけが床から離れた状態から、作業者が手押しハンドル（２８）を前方へ押して、車輪（１２）も床から浮かせて保持している状態である。 Next, a method of turning the floor material peeling device (1) of the present invention will be described. In FIG. 2A, the turning member (13) is grounded and fixed to the floor, the wheels (12) and the turning member (13) are grounded to the floor, and only the floor material separating blade (11) is removed from the floor. The operator pushes the hand push handle (28) forward from a state in which the wheel (12) is lifted from the floor and holds it.
本発明の床材剥離装置（１）では、手押しハンドル（２８）の根元を、車台（２）の、旋回部材（１３）に近いところに取り付けているので、作業者は小さい力で床材剥離装置（１）を図２（ａ）の状態に、旋回部材（１３）だけ接地した状態に保持できる。 In the floor material peeling device (1) of the present invention, since the base of the hand-pushing handle (28) is attached to the chassis (2) near the turning member (13), the worker peels the floor material with a small force. The device (1) can be held in the state of FIG. 2(a), with only the turning member (13) being in contact with the ground.
図２（ａ）の状態で、作業者は床材剥離装置（１）を、旋回部材（１３）の旋回中心で旋回させる。すなわち旋回部材（１３）の接地板（１３ａ）を床に接地させて旋回軸（１３ｂ）を接地板（１３ａ）に対して旋回中心で旋回させるのである。 In the state of FIG. 2A, the worker turns the floor material peeling device (1) around the turning center of the turning member (13). That is, the grounding plate (13a) of the turning member (13) is grounded to the floor, and the turning shaft (13b) is turned around the turning center with respect to the grounding plate (13a).
本発明の床材剥離装置（１）では、ハンドルグリップ（３）が、車台（２）の後端よりも前方の位置になるように手押しハンドル（２８）を取り付けているので、作業者は床材剥離装置（１）から離れることなくの旋回の中心に近いところに立つことができる。 In the floor material peeling apparatus (1) of the present invention, since the handle grip (3) is attached with the hand-pushing handle (28) so that the handle grip (3) is located at a position in front of the rear end of the chassis (2), the operator is forced to use the floor. It is possible to stand near the center of turning without leaving the material peeling device (1).
図２（ｂ）は、床材剥離装置（１）を時計回りに１８０°旋回させた時の軌跡を示している。点Ｏは旋回の中心であり、旋回部材（１３）の旋回中心点である。円弧Ａ１からＡ２は床材剥離刃板（１１）の移動軌跡であり、点Ｏから円弧Ａ１からＡ２までが床材剥離装置（１）の回転半径であり、円弧Ｂ１からＢ２は作業者の腰の移動軌跡であり、点Ｏから円弧Ｂ１からＢ２までが作業者の回転半径である。
Ｗは床材剥離装置（１）の回転半径と作業者の回転半径の和であり、発明の床材剥離装置（１）では、Ｗは約１０００ｍｍであり、１０００ｍｍの床幅がれば床材剥離装置（１）を旋回させることができる。
FIG.2(b) has shown the locus|trajectory at the time of rotating the flooring material peeling apparatus (1) 180 degrees clockwise. Point O is the center of turning and is the turning center point of the turning member (13). Arcs A1 to A2 are the movement loci of the floor material peeling blade plate (11), arcs A1 to A2 are the turning radii of the floor material peeling device (1), and arcs B1 to B2 are the waist of the worker. And the arcs B1 to B2 from the point O to the turning radius of the operator.
W is the sum of the radius of gyration of the floor material peeling device (1) and the radius of gyration of the operator. In the floor material peeling device (1) of the invention, W is about 1000 mm, and if the floor width is 1000 mm, the floor material is The stripping device (1) can be swiveled.
続いて、旋回部材（１３）の固定、すなわちアーム（１４）とセットレバー（１８）を解除する方法について図２（ａ）を用いて説明する。作業者は手押しハンドル（２８）を自分の方向へ引いて図２（ａ）の状態から車輪（１２）を床に接地させ、更に手押しハンドル（２８）を自分の方向へ引くとアーム（１４）は反時計回りに回動し、係止部（１９）が係止部受部（１６）から外れる。セットレバー（１８）は、セットレバー重り（２０）により反時計回りに回動し、プランジャー（２２）がプランジャー受け孔（２２）にはまり込む直前で停止する。作業者はセットレバー取手（２５）を持ち上げて、プランジャー（２２）をプランジャー受け孔（２２）にはまり込ませるとセットレバー（１８）は固定される。アーム（１４）の係止受部（１６）を設けている側の重量を重り（図示せず）を設けるなど重くしているので、アーム（１４）が図２（ａ）において時計周りに回動して旋回部材（１３）が浮き上がり解除が完了する。 Subsequently, a method of fixing the turning member (13), that is, a method of releasing the arm (14) and the set lever (18) will be described with reference to FIG. The operator pulls the hand push handle (28) toward his/her direction to ground the wheel (12) to the floor from the state shown in FIG. Rotates counterclockwise, and the locking portion (19) is disengaged from the locking portion receiving portion (16). The set lever (18) is rotated counterclockwise by the set lever weight (20) and stopped immediately before the plunger (22) is fitted into the plunger receiving hole (22). The operator lifts the set lever handle (25) to fit the plunger (22) into the plunger receiving hole (22), whereby the set lever (18) is fixed. Since the weight of the side of the arm (14) on which the lock receiving portion (16) is provided is made heavy by providing a weight (not shown), the arm (14) rotates clockwise in FIG. 2(a). The swiveling member (13) is lifted by moving and the release is completed.
図３は、旋回部材（３３）の別の実施形態を説明した図である。床材剥離装置（１）の構成はほぼ同じであるので、同じ作用のものは図１の符号と同様の符号で表示している。 FIG. 3 is a diagram illustrating another embodiment of the turning member (33). Since the floor material peeling device (1) has almost the same configuration, the same functions are indicated by the same reference numerals as those in FIG.
旋回部材支持軸（２７）はアーム（１４）に固定されて回転しないようにされており、旋回部材支持軸（２７）に旋回部材（３３）が図３（ｂ）に示すように旋回部材支持軸（２７）の中央付近に固定されている。この旋回部材（３３）は、床に接地する接地面（３３ａ）が球面とされており、床面に点で接地するようにしており、旋回部材（３３）だけで接地させた状態とした場合に旋回しやすい構成としているのである。旋回部材（３３）だけで接地させる手順や、解除の手順は図１、図２を用いた実施形態で説明した内容と同様の手順である。本実施形態においても、床材剥離装置（１）の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板（１１）が床から離れ、車輪（１２）と旋回部材（３３）により床に接地された状態となる。 The swivel member support shaft (27) is fixed to the arm (14) so as not to rotate, and the swivel member support shaft (27) supports the swivel member (33) as shown in FIG. It is fixed near the center of the shaft (27). The turning member (33) has a spherical grounding surface (33a) that comes into contact with the floor, and is designed to be grounded at a point to the floor surface. When the turning member (33) alone is grounded It has a structure that makes it easy to turn. The procedure for grounding only with the turning member (33) and the procedure for releasing are the same procedures as described in the embodiment using FIGS. 1 and 2. Also in this embodiment, since the floor material stripping device (1) contacts the floor in front of the center of gravity in the front-rear direction, the floor material stripping blade plate (11) separates from the floor and the wheels (12). With the turning member (33), the floor is grounded.
図４は、図３の旋回部材（３３）と同様の部材を旋回部材支持軸（２７）に床材剥離装置（１）の本体左右端部付近にそれぞれ旋回部材（４３ａ）と旋回部材（４３ｂ）として設けたものである。旋回部材（４３ａ）には接地面（４３ｃ）が、旋回部材（４３ｂ）には接地面（４３ｄ）がそれぞれ旋回部材（３３）と同様に球面状に設けられている。 FIG. 4 shows a swivel member (43a) and a swivel member (43b) which are similar to the swivel member (33) in FIG. 3 and which are attached to the swivel member support shaft (27) near the left and right ends of the floor material peeling device (1). ) Is provided. The turning member (43a) is provided with a grounding surface (43c), and the turning member (43b) is provided with a grounding surface (43d) in the same spherical shape as the turning member (33).
右旋回する場合は右の旋回部材（４３ｂ）を中心に回転させてもよく、あるいは、左旋回する場合は左の旋回部材（４３ａ）を旋回の中心として床材剥離装置（１）を回転させるのである。 When making a right turn, the right turning member (43b) may be rotated, or when making a left turn, the floor turning device (1) is turned around the left turning member (43a) as a turning center. Let them do it.
本実施形態においても、床材剥離装置（１）の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板（１１）が床から離れ、車輪（１２）と旋回部材（４３ａ）、旋回部材（４３ｂ）により床に接地された状態となる。 Also in this embodiment, since the floor material stripping device (1) contacts the floor in front of the center of gravity in the front-rear direction, the floor material stripping blade plate (11) separates from the floor and the wheels (12). With the turning member (43a) and the turning member (43b), the floor is grounded.
図５は、旋回部材（４５）を駆動源（４６）で昇降させる構成とした実施形態である。図５の実施形態においては駆動源（４６）はシリンダとしている。旋回部材（４５）はシリンダのロッドの先端に回転自在に取り付けられている。
駆動源（４６）は、床材剥離装置（１）の底部に設けるのが望ましいが、スペースがないようであれば、床材剥離装置（１）の側面や上面に設けてもよい。側面や上面にシリンダを設けた場合、床材剥離装置（１）の底部で昇降させる旋回部材（４５）と連結するための金具等を適宜設計し取り付けておけば良いのである。このシリンダは油圧式でも空圧式でも良い。
本実施形態においても、床材剥離装置（１）の前後方向の重心よりも前方で床に接地する様にしているので、床材剥離用刃板（１１）が床から離れ、車輪（１２）と旋回部材（４５により床に接地された状態となる。
シリンダに油又は空気を送るためのユニットも床材剥離装置（１）の側面や上面の床材剥離作業の邪魔にならない位置に適宜金具等で取り付けてカバーなどを設置しておくと良い。またシリンダ以外の例えばパンタグラフ式の昇降機構を採用することも可能である。また、旋回部材は回転自在に設けた実施形態で説明したが、図３で説明した実施形態の旋回部材（３３）と同様なものであっても良い。
FIG. 5 shows an embodiment in which the turning member (45) is moved up and down by the drive source (46). In the embodiment of FIG. 5, the drive source (46) is a cylinder. The turning member (45) is rotatably attached to the tip of the rod of the cylinder.
The drive source (46) is preferably provided at the bottom of the floor material peeling device (1), but may be provided on the side surface or the top surface of the floor material peeling device (1) if there is no space. When the cylinder is provided on the side surface or the upper surface, a metal fitting or the like for connecting to the swivel member (45) that moves up and down at the bottom of the floor material peeling device (1) may be appropriately designed and attached. This cylinder may be hydraulic or pneumatic.
Also in this embodiment, since the floor material stripping device (1) contacts the floor in front of the center of gravity in the front-rear direction, the floor material stripping blade plate (11) separates from the floor and the wheels (12). And the turning member (45 causes the floor to be grounded.
It is preferable that a unit for sending oil or air to the cylinder is appropriately attached with a metal fitting or the like at a position on the side surface or the upper surface of the floor material peeling device (1) that does not interfere with the floor material peeling work and a cover or the like is installed. It is also possible to employ, for example, a pantograph type lifting mechanism other than the cylinder. Further, although the turning member has been described in the embodiment in which it is rotatably provided, it may be the same as the turning member (33) of the embodiment described in FIG.
また、床材剥離用刃板（１１）の交換などのメンテナンスの際にも、セットレバー（２５）を押し下げて旋回部材（１３）が下に突き出した状態で固定すれば、旋回部材（１３）と車輪（１２）が床に接地して床材剥離用刃板（１１）が床から浮いた状態になるので、作業者は床材剥離装置（１）を倒さなくても交換などのメンテナンスできる。 Also, during maintenance such as replacement of the floor material peeling blade plate (11), the turning member (13) can be fixed by pushing down the set lever (25) so that the turning member (13) projects downward. Since the wheel (12) and the wheel (12) are in contact with the floor and the floor material peeling blade plate (11) floats from the floor, the operator can perform maintenance such as replacement without tilting the floor material peeling device (1). ..
また、アーム支点（１５）を後方に取り付けて旋回部材（１３）や図３〜図５に開示した実施形態において、床材剥離装置（１）の前後方向の重心位置よりもやや後方にすれば、床材剥離装置（１）は床材剥離用刃板（１１）と旋回部材（１３）が接地した状態にできる。このようにした場合、床材剥離装置（１）を旋回させる場合（図２（ａ）の場合）、作業者は手押しハンドル（２８）を少し後方へ（作業者自身が自分の方に引き寄せる方向）に保持することになるので、作業者はより安定した姿勢で旋回できる。なお、このようにした場合、床材剥離用刃板（１１）を交換する際は、刃物ブラケット（１０）の後方の床にリン木をあてがうなどの方法で床材剥離用刃板（１１）を床から浮かせば床材剥離装置（１）を倒さなくても床材剥離用刃板（１１）を交換することができる。
Further, if the arm fulcrum (15) is attached to the rear side and in the embodiment disclosed in the swiveling member (13) and FIGS. The floor material peeling device (1) can be in a state where the floor material peeling blade plate (11) and the turning member (13) are grounded. In this case, when the floor material peeling device (1) is turned (in the case of FIG. 2A), the worker pushes the hand handle (28) slightly backward (in the direction in which the worker pulls it toward himself). ), the worker can turn in a more stable posture. In this case, when replacing the floor material peeling blade plate (11), the floor material peeling blade plate (11) is applied by applying phosphorus wood to the floor behind the blade bracket (10). If the floor material is lifted from the floor, the floor material peeling blade plate (11) can be replaced without tilting the floor material peeling device (1).
