Unexamined-Japanese-Patent No. 2017-200738

  Here, in the work using the covering work support device of Patent Document 1, since the sheet is positioned with respect to the sticking surface by the magnetic attraction force, basically, the work can be performed by one worker. However, at present, work related to coating is often performed without using magnetic attraction. When performing work on coating without using magnetic attraction (for example, when coating a sheet on a frame (frame) of a backboard to manufacture a so-called backboard), basically, the sheet to be coated is a sheet It is necessary to carry out the direct work (for example, work to fix a sheet to a covering subject and to correct the distortion of a sheet to a covering subject. Hereinafter, "direct covering work") for covering the There is. Then, when performing work using the covering work support device, it is difficult for one worker to directly perform the covering work while moving the device. The work is performed by a mobile worker (hereinafter referred to as "mobile worker") and a worker (hereinafter referred to as "directly coated worker") who directly performs the coating operation.

  When the mobile worker and the direct coating worker cooperate to perform the coating operation using the coating operation support device (mobile carriage) of Patent Document 1, the mobile worker pulls the device and moves it in the first direction 105. Direct covering workers to perform direct covering work efficiently by performing direct covering work while being directly positioned in the second direction 106 with respect to the apparatus. Can. In this case, the transfer operator does not intervene between the sheet body (the portion where the sheet 101 is wound) and the direct covering operation, and the direct covering operator is in the position near the sheet body, covering operation support device This is because the coating operation can be performed directly with little distortion occurring in the sheet 101 fed from the sheet main body according to the movement of the sheet. As the distance between the sheet body and the direct covering operator increases, the portion drawn out from the sheet body is bent by its own weight, and the efficiency of the direct covering operator's work decreases.

  Generally, pushing and moving the device is not necessary to move with the back toward the moving direction of the device rather than pulling and moving the device, and pushing the handle is more efficient than pulling it. The ability to apply force makes it easy for mobile workers to work. However, the covering operation support device of Patent Document 1 has the following problems when the mobile worker presses and uses the device. That is, in the case of the case where the mobile operator pushes and moves the apparatus, the mobile operator holds the handle 104 and presses the apparatus, so the direct coating operator performs the operation while being positioned behind the mobile operator. It will be. This is because in order to perform the direct covering operation properly, the covering operator needs to be located directly on the opposite side of the moving direction of the device with respect to the sheet body. In this case, while the work related to the covering is being performed, the moving worker is directly interposed between the covering operator and the sheet main body, so that the position of the direct covering operator and the sheet main body is separated by that much As a result, there is a problem that the direct coating operator can not work efficiently.

  The present invention has been made to solve such problems, and it is not only the case of pulling and moving the device, but also the worker who directly performs the covering work when the device is pushed and moved. The purpose is to enable efficient work.

  In order to solve the problems described above, in the present invention, a support member extending along the ground, a caster provided on the support member, and one end of the support member in the front-rear direction are provided. A covering work support device for a handle for applying a moving force, and a support bar provided on the other end side of the support member in the front-rear direction with respect to the handle and capable of inserting the core of a rolled sheet , And the handle and the support bar are spaced apart in the front-rear direction so as to form a working space between the handle and the support bar so that the operator can stay.

  According to the present invention configured as described above, when the mobile worker who moves the device pushes and moves the device, the direct coating worker who performs the work related to the direct coating has a handle operated by the mobile worker and It is possible to work while staying in the working space formed between the seat body and the supporting bar attached. For this reason, when the covering operation support device is used by pressing, the moving operator does not intervene between the sheet main body and the direct covering operator, and the direct covering operator works at a position closer to the sheet main body. The work can be performed efficiently in a state in which the influence of the bending of the sheet fed out from the sheet main body is small. In addition, when the mobile worker moves the apparatus by pulling it, the direct coating worker can work while staying on the opposite side of the handle with the pointer rod in between. Also in this case, the transfer operator is not interposed between the sheet main body and the direct cover operator, and the direct cover operator can efficiently work at a position near the sheet main body. That is, according to the present invention, not only in the case of pulling and moving the device but also in the case of pressing and moving the device, the worker who performs the direct work on the covering can perform the work efficiently.

  FIG. 4 (B) is an example of a sheet coated on the frame 7 of FIG. 4 (A). The sheet 14 shown in FIG. 4B is a cloth member which has substantially the same size and shape as the front surface of the frame 7 when the sheet 14 is spread. On the back surface of the sheet 14, a sheet upper side surface fastener 15 made of a surface fastener is attached along the upper side when the surface is viewed from the front, and a sheet lower side surface fastener 16 is attached along the lower side. The surface fastener 17 is attached, and the sheet left side surface fastener 18 is attached along the left side. The sheet 14 is coated on the front surface of the frame 7 by connecting the surface fasteners 15 to 18 on the sheet 14 side to the surface fasteners 8 to 11 on the frame 7 side.

  The covering work support device 1 according to the present embodiment covers the sheet against the surface of the object to be covered, like the work of covering the sheet 14 of FIG. 4B on the front of the frame 7 of FIG. It is used to support the work done by the worker at the time of work. In the following, the structure and function of the covering operation support device 1 and the covering operation support device 1 will be described taking the case of using the frame 7 of FIG. 4A as appropriate for covering the sheet 14 of FIG. The work etc. of the worker performed using it are explained.

  As shown in FIGS. 1 to 3, the covering operation support device 1 has a support member 20. The support member 20 includes a rear support member 21 (corresponding to “one support member” in the claims of the utility model registration) and a front support member 22 disposed in front of the rear support member 21 so as to be separated from the rear support member 21. (Corresponding to "other support member" in the claims of the utility model registration). The rear support member 21 and the front support member 22 are connected by a rod-like connecting member 2 that connects the center in the width direction (= horizontal direction) of the rear support member 21 and the center in the width direction (= horizontal direction) of the front support member. It is connected in the state spaced apart to the front-back direction.

  The front support member 22 includes a support rod support 23 and a front caster support member 24 provided continuously with the support rod support 23 in front of the support rod support 23. Corresponding to the member). The support rod support 23 is a plate-like member extending along the ground, and when viewed from above, a substantially rectangular upper surface 23a is formed, with the sides in the left-right direction longer than the sides in the front-rear direction (See especially Figure 3).

  The connection member 2 is connected to the front caster support member 24 through the center in the left-right direction of the upper surface 23 a of the support rod support 23. The support rod support 23 is fixed to the connection member 2 by fixing the upper surface 23 a of the support rod support 23 and the lower surface of the connection member 2 by welding or other means. Further, at the rear end portion of the upper surface 23 a of the support bar support 23, a reinforcing member 25 is provided which reinforces the fixing of the support bar support 23 to the connection member 2. The height T1 of the upper surface 23a of the support rod support 23 from the ground is, for example, about "10 mm" to "20 mm", and the upper surface 23a is positioned very near to the ground. At the rear end of the support rod support 23, a pair of front foot support members 26R, 26L (which correspond to the "installation part" and "the other foot support" in the claims of the utility model registration request) projecting upward ) Are spaced apart in the left-right direction across the reinforcing member 25. The function of the front foot support members 26R, 26L will be described later.

  A pole-shaped right support rod 27R is erected on the right end portion of the support rod support 23 in a state of being erected upward. In addition, a pole-like left support rod 27L is erected at the left end portion of the support rod support 23 in a state of being erected upward. The length of the right side support bar 27R and the length of the left side support bar 27L are the same. Hereinafter, when the right side support bar 27R and the left side support bar 27L are not distinguished from one another, they are expressed as “support bars 27R and 27L”. The support rods 27R and 27L are the core of the sheet wound in a roll (a cylindrical core member around which the sheet is wound, or a center formed by winding the sheet if there is no core member). (The hollow part of the part) can be inserted. Hereinafter, for convenience of explanation, a roll-shaped portion wound around the support rods 27R and 27L in the sheet is referred to as a “sheet main body”, and a portion drawn out from the sheet main body is referred to as a “discharged sheet”. In FIG. 2, a state in which the sheet main body 28 configured by the sheet 14 in FIG. 4B is attached to the left support rod 27L is schematically represented by a broken line.

  The sheet rotates in a specific direction depending on the direction in which the covering work support device 1 is moved during the covering work and whether the covering object is positioned on the right side or the left side with respect to the covering work support device 1 It is selectively attached to one of the support rods 27R and 27L so as to rotate in a direction. How the rotational direction of the sheet when attached to the support rods 27R, 27L is determined, and how the support rods 27R, 27L for attaching the sheet are selected will be described later.

  The front caster support member 24 of the front support member 22 is a member integrally formed with the connection member 2 and has a shape such that the connection member 2 penetrates the hollow portion of the rectangular frame-like member when viewed from above (See especially Figures 1 and 3). A notch is formed below the left portion of the front caster support member 24, and a left front wheel caster 30 which is a caster (wheel) is provided in the notch. Although not shown, a notch is also formed below the right portion of the front caster support member 24 and a right front wheel caster is provided in the notch.

  The left front connecting member 31 is fixed to the left end of the upper surface of the front caster support member 24, and the left front stopper 32 is attached to the front of the left front connecting member 31. That is, the left front stopper 32 is attached and fixed to the front caster support member 24 via the left front connecting member 31. The left front stopper 32 is a member for positioning the support member 20 with respect to the ground in cooperation with other stoppers, and in response to the operation of the lever 33, a flat contact surface facing the ground is formed. The ground contact member 34 is configured to move. When the ground contact member 34 is locked while being moved downward, the movement of the ground contact member 34 is restricted while the contact surface is in contact with the ground, and a frictional force is generated between the contact surface and the ground to cause contact with the ground. The movement of the support member 20 is restricted. A right front stopper 37 is attached to the right end portion of the upper surface of the front caster support member 24 via the right front connecting member 36. The structure and function of the right front stopper 37 are similar to those of the left front stopper 32.

  As described above, the upper surface 23a of the support bar support 23 is located very near to the ground. By setting the position of the upper surface 23a of the support bar support 23 to a position close to the ground as described above, the following advantages can be obtained. That is, when the covering object to be covered with the sheet is erected on the ground like the frame 7 of FIG. 4, the sheet main body 28 attached to the lower end of the covering object and the support rods 27R and 27L. The lower end of the sheet can be made as close as possible, and when the discharged sheet drawn from the sheet body 28 is covered with the covering object, the discharge is performed to align the lower end of the covering object with the lower end of the discharged sheet. There is no need to pull the sheet downward, which makes the operation efficient.

  In the present embodiment, the front support member 22 is provided with the support rod support 23 for supporting the support rods 27R and 27L as separate members from the front caster support member 24 that supports the caster functioning as the front wheel. The support member 24 and the support rod support 23 are arranged to be offset in the front-rear direction. For this reason, the position of the upper surface 23a of the support rod support 23 (the position of the lower end of the support rods 27R and 27L) can be set lower than the upper end of the casters without being affected by the presence of the casters. For example, although a caster may be provided below the support bar support 23, in this configuration, the height of the support bar support 23 can not be made lower than the upper end of the caster. The height of the support bar support 23 is increased compared to the form.

  As shown in FIGS. 1 to 3, the rear support member 21 is configured by a rear caster support member 40 configured integrally with the connection member 2. That is, in the covering work support device 1, the connection member 2, the front caster support member 24 and the rear caster supporting member 40 are integrally configured, and function as a framework of the covering work support device 1. The rear caster support member 40 has a shape in which the connection member 2 penetrates the hollow portion of the rectangular frame-like member when viewed from above (in particular, see FIGS. 1 and 3). Notches are formed below the right and left portions of the rear caster support member 40, respectively. The left rear wheel caster 41 is provided in the notch of the left part, and the right notch is provided with the right. Rear wheel casters (not shown) are provided.

  The left rear stopper 43 is attached to the left end of the upper surface of the rear caster support member 40 via the left rear connection member 42, and the right rear stopper 45 is attached to the right end of the upper surface via the right rear connection member 44. It is attached. The structure and function of the left rear stopper 43 and the right rear stopper 45 are the same as those of the left front stopper 32 described above. The left rear connection member 42 and the right rear connection member 44 respectively function as a pair of rear foot support members 46R and 46L (corresponding to "installation part" and "one foot support part" in the claims of the utility model registration) . The function of the rear foot support members 46R and 46L will be described later.

  At the rear end of the rear caster support member 40, a handle 3 is provided. The handle 3 has a proximal end fixed to the rear caster support member 40 and extends upward from the proximal end while being gently curved rearward, and is a handle support member 48 to which the gripping member 4 is attached at the distal end. Have. The gripping member 4 is a rod-like member extending in the left-right direction. The operator can open both hands horizontally and grip the gripping member 4 with both hands while being positioned behind the handle 3 and with the front of the body facing forward.

  The handle 3 is a member for applying a force to move the covering work support device 1. With the front of the body facing forward, the worker horizontally opens both hands and grips the gripping member 4 with both hands. The operator can push the handle 3 to move the covering work support device 1 forward so that the covering work support device 1 moves forward while holding the gripping member 4 with both hands. Furthermore, the operator can pull the handle 3 so as to move the covering operation support device 1 rearward so that the covering operation support device 1 moves backward while holding the gripping member 4 with both hands. In addition, the worker can apply a suitable force to the handle 3 to move the covering work support device 1 while moving the covering work support device 1 forward or backward.

  As shown to FIGS. 1-3, the front support member 22 and the back support member 21 are spaced apart and arrange | positioned at the front-back direction. Thus, a working space 50 (see FIGS. 1 and 3) in which the ground is exposed is formed between the rear end of the front support member 22 and the front end of the rear support member 21. More specifically, a right working space 50R where the ground is exposed is formed in the area on the right side of the connection member 2 and between the front support member 22 and the rear support member 21. In the region between the front support member 22 and the rear support member 21, a left working space 50L is formed with the ground exposed. The right side work space 50R and the left side work space 50L are respectively large enough for workers to stay. The work space 50 is a space for a worker to stay and work in direct work related to coating (hereinafter, referred to as "direct coating work"). The direct covering operation is, for example, an operation of connecting the surface fastener on the side of the sheet 14 to the surface fastener on the side of the frame 7 while suppressing the bending of the sheet 14, etc. This means work, and does not include work for moving the covering work support device 1.

  Hereinafter, when covering the sheet | seat 14 of FIG. 4 (B) to the flame | frame 7 of FIG. 4 (A), the operation | work which a worker performs using the covering operation assistance apparatus 1 is explained in full detail. In addition, the work related to the covering using the covering work support device 1 is a worker who moves the covering work support device 1 (hereinafter, referred to as “moving worker”) and a worker who performs the covering work directly (hereinafter, “direct covering” It is performed by "worker".

  When covering the sheet 14 on the frame 7, first, the sheet main body 28 formed by winding the sheet 14 in a roll shape with respect to the core member is attached to one of the support rods 27R and 27L. FIG. 5 is a diagram used for explaining the method of selecting the support rods 27R and 27L to which the sheet main body 28 is attached and the rotation direction of the sheet main body 28 attached to the support rods 27R and 27L. In FIG. 5, the top view of the coating operation assistance device 1 is simplified and schematically represented. FIG. 5 is also used later to describe the positional relationship between the mobile worker and the direct coating worker when the coating operation support device 1 moves rearward.

  As described above, the covering work support device 1 can also be used as being moved forward as the advancing direction, and can also be used backward as the advancing direction. In the case where the covering object is positioned on the right side of the covering work support device 1 when the forward direction is the advancing direction, the sheet main body 28 is attached to the right side support rod 27R when the covering work support device 1 is used . Further, in this case, the sheet main body 28 is attached to the right side support rod 27R such that when the discharged sheet is fed out from the sheet main body 28, the sheet main body 28 rotates according to the arrow K1 in FIG.

  When the covering object is positioned on the left side of the covering work support device 1 with the front as the advancing direction, the sheet body 28 rotates in accordance with the arrow K2 in FIG. 5 when the discharged sheet is drawn out. It is attached to the left side support rod 27L. When the object to be covered is positioned on the right side (the left side in the direction of movement) of the covering operation support device 1 with the rear as the direction of movement, the sheet body 28 pulls the discharge sheet in FIG. Is attached to the right side support rod 27R while being rotated according to the arrow K3 of FIG. When the object to be covered is positioned on the left side (the right side in the direction of movement) of the coated working wire device _ with the rear as the direction of movement, the sheet body 28 pulls the discharged sheet in FIG. Is attached to the left support rod 27L while being rotated in accordance with the arrow K4 of FIG.

  In the following description, it is assumed that the traveling direction of the covering work support device 1 is the front, and the frame 7 as the covering object is located on the right side of the covering work support device 1 during use of the covering work support device 1 I assume. In this case, as described above, the sheet main body 28 is attached to the right side support bar 27R in a state of rotating according to the arrow K1 in FIG. 5 when the discharged sheet is delivered.

  FIG. 6 is a view used for explaining the operation of covering the sheet 7 on the frame 7. Each of FIGS. 6A to 6C shows the frame 7, the covering work support device 1 and the workers (moving workers and direct covering workers) viewed from above, respectively (A) → It becomes time series in the order of (B) → (C). In each of FIGS. 6A to 6C, the covering operation support device 1 is schematically drawn in a simplified manner.

  After the attachment of the seat body 28 to the right side support bar 27R is completed, the mobile operator appropriately applies a force while operating the handle 3, and as shown in FIG. 6A, the right side support bar 27R is a frame The covering work support device 1 is moved in the vicinity of the right side of 7 so as to be positioned slightly ahead of the right side.

  In this state, the direct coating worker stays in the right working space 50R and performs the following work in the right working space 50R. That is, as shown in FIG. 6A, the direct covering worker grips and pulls the end of the sheet 14 and feeds out the discharge sheet 51 from the sheet main body 28 to extend the frame right side surface fastener 10 extending in the vertical direction. Then, the sheet right side surface fastener 17 extending in the vertical direction is connected.

  After the connection between the frame right side surface fastener 10 and the sheet right side surface fastener 17 is completed, the mobile operator moves the covering work support device 1 forward by pushing the handle 3. Since the end of the discharge sheet 51 drawn out from the sheet body 28 is fixed to the frame 7 by the connection of the surface fastener, the discharge sheet 51 is moved along with the forward movement of the covering work support device 1. The tension acts, and the discharge sheet 51 is sequentially fed from the sheet main body 28. As shown in FIG. 6 (B), the direct covering worker is also moving according to the forward movement of the covering work support device 1 so as to be maintained in the right working space 50R. An operation is performed to connect the sheet upper side surface fasteners 15 of the discharge sheet 51 sequentially fed out to the frame upper surface side fasteners 8 and to connect the sheet lower side surface fasteners 16 to the frame lower side surface fasteners 9. As a result, in accordance with the forward movement of the covering operation support device 1, the range in which the sheet upper side surface fastener 15 and the frame upper side surface fastener 8 are connected, and the sheet lower side surface fastener 16 and the frame lower side surface fastener 9 The connected range gradually expands.

  When the covering work support device 1 is further moved forward, as shown in FIG. 6C, the right side support bar 27R of the covering work support device 1 is moved forward beyond the other end of the frame 7 and the sheet 14 The other end of the sheet is separated from the core member. The direct covering worker performs an operation of connecting the sheet left side surface fastener 18 extending in the up and down direction to the frame left side surface fastener 11 extending in the up and down direction while being positioned in the right side work space 50R. The sheet left side surface fastener 18 is connected to the fastener 11. Thus, the coating of the sheet 14 on the frame 7 is completed.

  Here, in the case of the operation illustrated with reference to FIG. 6, the covering operation support device 1 moves forward during the operation. In this case, the direct coating worker needs to be located rearward of the right side support bar 27R (opposite to the moving direction of the apparatus with respect to the right side support bar 27R) at the time of operation. Since the discharge sheet 51 is drawn out from the sheet main body 28 relatively backward as the covering work support device 1 moves forward, the work of covering the frame 7 while touching the discharge sheet 51 is performed. This is because it is necessary for the direct coating operator to be located rearward of the right side support bar 27R to which the sheet body 28 is attached.

  And in covering operation support device 1 concerning this embodiment, support rods 27R and 27L and handle 3 are estranged and arranged, and front support member 22 in which support rods 27R and 27L were provided, and handle 3 are provided. A right working space 50R is provided between the rear support member 21 and the rear support member 21. Therefore, when the mobile worker pushes and moves the coating operation support apparatus 1 while being located behind the handle 3, the mobile worker between the direct coating worker who stays in the right working space 50R and the right support rod 27R The covering operator directly covers the discharge sheet 51 fed from the sheet main body 28 at a position close to the sheet main body 28 attached to the right side support rod 27R without the moving operator being disturbed. It can be performed. For this reason, the direct coating worker can perform the work of connecting the surface fastener in a state in which the influence of the deflection generated due to the own weight of the discharge sheet 51 is small, and the work efficiency is good.

  In addition, the right side work space 50R is a space where the ground is exposed and a direct covering worker can work with his / her foot on the ground. For this reason, the direct covering worker who works in the right-hand working space 50R puts a foot on the ground and works in a stable state without being affected by the movement of the covering work support device 1 performed by the mobile worker. be able to.

  Further, during the operation of covering the sheet 14 with the frame 7, the direct covering operator can efficiently perform the operation when the distance between the sheet main body 28 attached to the support rods 27R and 27L and the frame 7 is short. This is because when the distance between the sheet body 28 and the sheet 7 is short, the sheet can be attached to the frame 7 in a state in which the deflection of the discharged sheet 51 drawn from the sheet body 28 is small. And in covering operation support device 1 concerning this embodiment, a pair of support rods 27R and 27L are provided upright at each end of support rod support stand 23 in the left-right direction (width direction). Therefore, regardless of the combination of the movement direction (front or back) of the covering work support device 1 and the relative position (right or left) of the frame 7 to the covering work support device 1, the side of the device is the frame 7 When the covering work support device 1 is disposed along the line, any one of the support rods 27R and 27L is always positioned near the frame 7. Therefore, by attaching the sheet main body 28 to the appropriate support rods 27R and 27L reflecting the moving direction of the device and the position of the frame 7, the covering object and the sheet main body 28 are always close during the operation. Direct coating workers can perform their work efficiently.

  If the width of the support bar support 23 is narrowed and one support bar is erected on the narrow support bar support 23, the movement direction and the covering object for the covering work support device 1 can be reduced. Regardless of the combination with the position, it is possible to make the coated object and the sheet body close. However, this method can not ensure a sufficient distance in the left-right direction between the castors, and the covering work support device 1 becomes an unstable device which is prone to fall in the left-right direction, and the work space 50 also becomes narrow. ,Not appropriate.

  In the above example, the work of the worker is described taking the case where the covering work support device 1 is moved forward and used as an example, but as described above, the covering work support device 1 is moved backward and used It is also possible. In this case, the mobile worker pulls and moves the covering work support device 1 while being positioned behind the handle 3 of the covering work support device 1. Further, the direct covering operator performs the direct covering operation in a state where the direct covering operator is located on the front side (the opposite side to the moving direction) than the front caster support member 24.

  FIG. 5 shows the positional relationship between the device, the mobile worker, and the direct coating operator when the coating operation support device 1 is used by moving it backward. As shown in FIG. 5, even when the covering work support device 1 is moved backward and used, the moving worker does not intervene between the support rods 27R and 27L to which the sheet main body is attached and the direct covering worker. The direct covering operator can perform the work of covering the discharged sheet drawn from the sheet main body at a position close to the sheet main body attached to the support rods 27R and 27L without the moving operator being in the way. Therefore, the direct coating operator can perform the work of connecting the surface fasteners in a state in which the influence of the deflection generated due to the own weight of the discharged sheet is small, and the work efficiency is good.

  Next, another way of using the coating operation support device 1 will be described. The frame 7 in FIG. 4A had a height such that the hand of the direct coating operator could easily reach the upper side of the frame 7. On the other hand, when the height of the object to be covered is such that the direct coverage worker can not reach (or hardly reach) the direct coverage worker, and the direct coverage worker stands on the ground, the direct covering operation is properly performed. In some cases it can not be done. In such a case, the covering work support device 1 is used in the following manner.

  That is, the stepladder 52 is prepared in advance. Then, the stepladder 52 is installed in the covering work support device 1. FIG. 7 is a view schematically showing how the stepladder 52 is installed in the covering work support device 1. In FIG. 7, the stepladder 52 is indicated by a broken line.
