Therefore, when the two girder members 126 move laterally with respect to the two basic members 121 by the lateral movement mechanism 125, the two beam members 133 also laterally move with respect to the two basic members 121. do.

On the upper side of each beam member 133, as shown in FIG. A short elevating member 134 is arranged with a small gap between it and the beam member 133 . The elevating member 134 is movable in the longitudinal direction with respect to the beam member 133. In order to smoothly move the elevating member 134 in the longitudinal direction with respect to the beam member 133, the elevating member 134 shown in FIG. As shown in FIG. 31 showing the member 134 in cross section, a longitudinal guide means 135 is provided between the beam member 133 and the lifting member 134 .

The front-back guide means 135 according to the present embodiment is connected to the lifting member 134 via a base member 136A (see also FIG. 26) of the pantograph mechanism 136 connected to the lower portion of the rear high portion 134B of the lifting member 134. As shown in FIGS. 33 and 34, which are cross-sectional views of the position where the bearing member 137 and the front-rear guide means 135 are arranged, the bearing member 137 is horizontally supported with its axial direction extending in the left-right direction. A shaft member 138, two guide rollers 139 rotatably attached to both ends of the shaft member 138, and two bearing members 137 are provided separately in the left-right direction, and their axial directions are vertical. and side rollers 141 rotatably attached to the shaft members 140 . The guide roller 139 and the side roller 141 are arranged inside a beam member 133 formed of channel material with a pair of upwardly opening lips 133A. The side roller 141 is shown in FIG. As shown, they are provided at both front and rear ends of the bearing member 137 . Therefore, the vertical movement of the lifting member 134 with respect to each of the beam members 133 is performed while the weight of the lifting member 134 is supported by the guide rollers 139. It moves accurately in the front-rear direction with respect to the beam member 133 without being shaken in the left-right direction. Therefore, the lifting member 134 also serves as a front-rear moving member that also moves in the front-rear direction.

As shown in FIG. 30, between the beam member 133 and the elevating member 134, or between the front girder member 126 and the elevating member 134 among the two girder members 126 to which the beam member 133 is connected. A forward/rearward movement mechanism 142 with a linear cylinder for moving the elevating member 134 in the forward/rearward direction with respect to the beam member 133 is arranged between them. Like the left-right movement mechanism 125, the front-rear movement mechanism 142 includes an electric motor, a male screw member rotated by the electric motor, and a female screw member screwed to the male screw member. Due to the movement of the female screw member due to forward and reverse rotation of the motor, the elevating member 134 moves forward and backward with respect to the beam member 133 while being guided by the forward and backward guide means 135 .

As shown in FIG. 25, the front-rear movement mechanism 142 of the present embodiment is provided on both sides in the left-right direction of the beam members 133 and the elevating members 134 that are arranged at the left and right end portions of the receiving table 120 . There are two types of back-and-forth moving mechanisms 142A and 142B. One of the back-and-forth moving mechanisms 142A is the front beam member 126 of the two beam members 126 to which the beam member 133 is connected, and the lifting member 134 side member. The other front-rear movement mechanism 142B is the beam member 133 and the pantograph mechanism 136 which is a member on the lifting member 134 side. It is bridged between the base members 136A. By arranging the two types of front-rear moving mechanisms 142A and 142B on both sides of the beam member 133 and the elevating member 134 in the left-right direction, the shutter curtain 1 is wound around the elevating member 134 as described later. Even if the weight of the winding shaft 2 , which is heavy as a whole, acts on the lift member 134 , the lift member 134 can be moved forward and backward relative to the beam member 133 as predetermined.

Note that one end of the forward/backward moving mechanism 142 is connected to the elevation member 134 instead of being connected to the base member 136A of the pantograph mechanism 136, so that the forward/backward moving mechanism 142 is connected to the beam member 133. Of the girder members 126 , it may be bridged between the front girder member 126 and the elevating member 134 or between the beam member 133 and the elevating member 134 .

As shown in FIG. 26, the pantograph mechanism 136 arranged between the high portion 134B formed at the rear portion of the lifting member 134 and the bearing member 137 of the longitudinal guide means 135 is arranged in a diamond shape. four link members 145-148 and a shaft for rotatably connecting the mutually approaching ends of the upper two link members 145, 146 to the upper member 136B connected to the higher portion 134B. 149, 150, shafts 151, 152 for rotatably coupling the ends of the two lower link members 147, 148 that are close to each other to the base member 136A, and one of the left and right directions. An electric motor 154 attached to a shaft 153 that rotatably connects the ends of two link members 146 and 148 arranged side by side, and a male screw that rotates forward and backward by the driving force of the electric motor 154. A rod 155 and two link members 145 and 147 screwed on the outer circumference of this male threaded rod 155 and arranged on the other side in the horizontal direction are attached to a shaft 156 that rotatably connects the ends of the two link members 145 and 147. and a female screw member 157. When the male threaded rod 155 is rotated forward and reverse by the electric motor 154, the female threaded member 157 moves in the longitudinal direction of the male threaded rod 155, so that the rhombic shape formed by the four link members 145 to 148 is deformed to form a lift member. 134 moves up and down with respect to the beam member 133 .

Therefore, the pantograph mechanism 136 also serves as a vertical movement mechanism 143 for vertically moving the lifting member 134 with respect to the beam member 133 . FIG. 35 shows a state in which the lifting member 134 is lifted with respect to the beam member 133 by the vertical movement mechanism 143. As shown in FIG.

Further, as shown in FIG. 31, between the beam member 133 and the lifting member 134, an X-shaped link mechanism 160 in which the first link member 158 and the second link member 159 are crossed in an X-shape is provided. are placed. As shown in FIGS. 33 and 34, the elevating member 134 is attached to the beam member 133 formed of a channel material having a pair of upwardly opening lip portions 133A, as shown in the cross-sectional view taken along the line S32-S32 in FIG. As shown in FIG. 32, the beam member 133 and the elevating member 134 are formed of a channel material with a pair of downwardly opening lips 134A. 160 are arranged in the left-right direction, and the first link member 158 and the second link member 159 of both X-shaped link mechanisms 160 are arranged at the central portion where these first and second link members 158 and 159 intersect. They are connected by a central shaft 161 that is rotatably provided. As can be seen from FIGS. 31 and 32, at one end of the first link member 158 in the length direction, a shaft 162A is rotatably supported by a bearing member 162 fixedly arranged inside the elevating member 134. A roller 163 is attached to the other end so as to be rotatable about a shaft 163A. Rollers 164 and 165 are attached to both ends of the second link member 159 in the longitudinal direction so as to be rotatable about shafts 164A and 165A. Roller 164 is arranged inside lifting member 134 , and rollers 163 and 165 are arranged inside beam member 133 .

As shown in FIG. 32, the roller 164 is placed on the inner upper surface of the lip portion 134A of the lifting member 134. As shown in FIG. Further, the shafts 162A, 163A, 164A, and 165A are common to the first link member 158 and the second link member 159 of the X-shaped link mechanism 160, which are arranged two left and right inside the beam member 133 and the elevating member 134. axis.

In the X-shaped link mechanism 160 described above, when the lifting member 134 is moved back and forth with respect to the beam member 133 by the back-and-forth movement mechanism 142, the rotation of the rollers 163 to 165 moves the lifting member 134 back and forth with respect to the beam member 133. move in the direction Further, when the elevation member 134 is vertically moved with respect to the beam member 133 by the vertical movement mechanism 143 by the pantograph mechanism 136, the first link member 158 and the second link member 159 are rotated around the center shaft 161. Due to the deformation of the X-shaped link mechanism 160 and the rotation of the rollers 163 to 165, the elevating member 134 moves vertically with respect to the beam member 133. As shown in FIG.

In this embodiment, the vertical movement mechanism 143 by the pantograph mechanism 136 is provided at one end in the length direction of the beam member 133 and the elevation member 134, specifically, the length of the beam member 133 and the elevation member 134. 30, 31 and 35, the X-shaped linkage 160 is located at the longitudinal end of the beam member 133 and the lift member 134 in the longitudinal direction. Alternatively, since it is arranged substantially in the center, the vertical movement of the lifting member 134 with respect to the beam member 133 by the vertical movement mechanism 143 can be performed while maintaining the parallel state or substantially parallel state of the lifting member 134 with respect to the beam member 133. It is possible.

As shown in FIG. 32, two wall members 166 are fixedly arranged on the upper surface of the lifting member 134 with a space left and right, and as shown in FIG. has a length in the front-back direction, a groove 167 whose length is in the front-back direction is formed on the upper surface of the lifting member 134 between two wall members 166 (FIG. 30). see also). As shown in FIG. 25, such grooves 167 are provided on the upper surface of each of the two elevating members 134 arranged at the left and right ends of the receiving table 120 . A mounting member 168 for mounting the winding shaft 2 on which the shutter curtain 1 is wound on the lifting member 134 is inserted into each groove 167 and has a vertical dimension larger than that of the wall member 166 . These mounting members 168 are provided on the receiving table 120 separately in the longitudinal direction of the winding shaft 2 in order to support the winding shaft 2 around which the shutter curtain 1 is wound. It is a supporting member.

As shown in FIGS. 25 and 30, the mounting member 168 according to the present embodiment is arranged in a horizontal direction perpendicular to the axial direction of the winding shaft 2 or in a substantially horizontal direction. It consists of two mounting half-members 168A. In addition, since the respective mounting half members 168A are placed in the grooves 167, the operator manually slides the mounting half members 168A to change the positions of the respective mounting half members 168A by sliding them forward and backward within the grooves 167. so that the longitudinal spacing of the two mounting halves 168A is adjustable.

In the receiving table 120 according to the present embodiment described above, when the two beam members 126 are moved in the horizontal direction with respect to the basic member 121 by the horizontal movement mechanism 125 shown in FIG. The two beam members 133 attached to the beam members 133 also move in the left-right direction, and the lifting members 134 arranged above these beam members 133 move through the pantograph mechanism 136 and the front-rear guide means 135 to move the beam members 133. are connected in the left-right direction, the elevating member 134 moves in the left-right direction together with the beam member 133, and the mounting member 168 arranged on these elevating members 134 also moves in the left-right direction. Further, when the lifting member 134 moves in the front-rear direction with respect to the beam member 133 by the front-rear moving mechanism 142 described above, the mounting member 168 also moves in the front-rear direction. Furthermore, when the elevation member 134 moves vertically with respect to the beam member 133 by the vertical movement mechanism 143 of the pantograph mechanism 136, the mounting member 168 also moves vertically.

Therefore, as supporting members for supporting the winding shaft 2 on which the shutter curtain 1 is wound, two mounting members 168 are arranged on the receiving table 120 apart in the lengthwise direction of the winding shaft 2. is arranged on the receiving table 120 so as to be capable of three-dimensional movement in the left-right, back-and-forth, and up-down directions by the left-right movement mechanism 125, the front-back movement mechanism 142, and the up-and-down movement mechanism 143.

Further, in the present embodiment, the two first intermediate members 122 and the second intermediate member 123, which are members constituting the receiving table 120, and the two intermediate members 123 coupled to the second intermediate member 123, are provided. The girder member 126 and the two beam members 133 coupled to each girder member 126 form a horizontal movement table 144 (see FIG. 25) that moves in the horizontal direction with respect to the basic member 121 by the horizontal movement mechanism 125. is configured. In addition, the elevating member 134 that moves in the front-rear direction with respect to the beam member 133 by the front-rear movement mechanism 142 also serves as a front-rear moving table that can move in the front-rear direction with respect to the left-right moving table 144. In this embodiment, Since there are two elevating members 134 , two front-rear moving bases are also provided on the receiving base 120 .

In addition, in this embodiment, two-dimensional movement is performed in the left-right direction and the front-rear direction by the left-right movement mechanism 125 and the front-rear movement mechanism 142 with respect to the basic member 121 by the left-right movement table 144 and the front-rear movement table by the elevating member 134 . Since a table is constructed and two mounting members 168 are arranged on the two lifting members 134, the two mounting members 168 are arranged on this two-dimensional movable table. There will be

In addition, since each lifting member 134, which is a front-rear moving base, moves vertically with respect to the left-right moving base 144 by the vertical movement mechanism 143, each front-rear moving base moves up and down with respect to the left-right moving base 144. One mounting member 168 consisting of two mounting half-members 168A is arranged for each of these front and rear movable bases.

Furthermore, in the present embodiment, each elevating member 134 is a member that moves vertically with respect to the beam member 133, and also serves as a front-rear moving base that moves longitudinally with respect to the beam member 133. Therefore, the receiving table 120 has a structure in which the members are shared.

In the receiving table 120 described above, a battery for supplying electric power to the electric motor of the left/right movement mechanism 125, the electric motor of the front/rear movement mechanism 142, and the electric motor 154 of the pantograph mechanism 136 serving as the up/down movement mechanism 143. , and a control device for controlling these electric motors are mounted on the cradle 120, although not shown. Further, the respective electric motors are driven and controlled by the control device to which a signal is sent from an operation device operated by an operator. Transmission of signals from the operating device to the control device may be wireless or wired using an electric cable. If it is wireless, the receiving table 120 is easy to handle because an electric cable is not connected to the receiving table 120 .

In addition, in this embodiment, the control device that receives the signal from the operating device individually drives the electric motors 154 of the two pantograph mechanisms 136 arranged as the vertical movement mechanisms 143 at the left and right ends of the receiving table 120 . It is to be controlled. For this reason, each pantograph mechanism 136 is individually driven by an operation by an operation device and a control device that operates based on this operation, thereby allowing each of the pantograph mechanisms 136 to move vertically. The height positions of the mounting members 168 arranged on the member 134 can be individually adjusted.

Furthermore, in this embodiment, the control device individually controls the electric motors of the front-rear movement mechanisms 142 provided for each of the two beam members 133 and the lifting members 134 arranged at the left and right ends of the receiving table 120. It is driven and controlled. Therefore, each of the forward and backward moving mechanisms 142 is also individually driven by the operation of the operation device and the control device that operates based on this operation, and thereby each of the forward and backward moving mechanisms 142 moves forward and backward. The position in the front-rear direction of the mounting member 168 arranged on the lifting member 134 can also be individually adjusted.

FIG. 24 shows a state in which the receiving table 120 described above is set on the forks 181 of a forklift vehicle 180. This forklift vehicle 180, which is lifting means for lifting the receiving table 120, is shown in FIG. 3 is brought to the floor 34 in the building where the installation work of the doorway shutter device described in 3 is carried out. The fork 181 that moves up and down with respect to the main body of the forklift vehicle 180 has a vertically extending portion 181A that extends in the vertical direction, and a forward extending portion 181C that extends forward from the lower end of the vertically extending portion 181A via a connecting portion 181B. It is L-shaped or substantially L-shaped. After the receiving table 120 is placed on the floor 34, the forklift vehicle 180 is moved forward by lowering the fork 181 so that the forward extending portion 181C of the fork 181 is formed by the rectangular tubular member of the receiving table 120. It is inserted inside the base member 121 . As a result, the receiving table 120 is set on the forks 181 of the forklift vehicle 180 .

FIG. 25 shows the relationship between the basic member 121 and the fork 181 at this time, with the fork 181 indicated by a chain double-dashed line. An opening 121A for inserting the vertically extending portion 181A and the connecting portion 181B of the fork 181 is formed in the upper surface of the rear end of each basic member 121, and the rear end surface of the basic member 121 is also opened in the opening 121A. It is supposed to At the rear end of each basic member 121, a slip-out prevention means 183 is provided that blocks a part of the opening 121A that opens the rear end face of the basic member 121. As shown in FIG. The escape prevention means 183 consists of a bolt 184 with which the shaft portion 184A crosses the opening 121A in the lateral direction, and a nut 185 screwed onto the end portion of the shaft portion 184A outside the basic member 121. A shaft portion 184A forming a main part of the slip-out preventing means 183 is located behind a connecting portion 181B that connects the vertically extending portion 181A and the forward extending portion 181C of the fork 181 in a curved manner. A portion of the opening 121A that opens the rear end surface of the base member 121 is partially closed (see also FIG. 24 showing the removal preventing means 183).

For this reason, after the receiving table 120 is set on the forks 181 of the forklift vehicle 180 as described above, when the removal preventing means 183 consisting of the bolt 184 and the nut 185 is attached to the basic member 121, the basic member 121 extends forward of the fork 181. The forward escape from the projecting portion 181C is prevented by the shaft portion 184A of the bolt 184 of the escape prevention means 183 coming into contact with the connecting portion 181B of the fork 181, thereby preventing the receiving table 120 from falling off the fork 181. can be set in a stable state. In addition, since the pull-out prevention means 183 consists of the bolt 184 and the nut 185 that can be separated from the basic member 121 , by separating the bolt 184 and the nut 185 from the basic member 121 , the receiving table 120 can be attached to the fork 181 . It is also possible to remove from

Therefore, the receiving table 120 according to the present embodiment is an attachment table that is detachably set on the fork 181 of the forklift vehicle 180 which is a lifting means for lifting the receiving table 120 .

As described above, the shutter curtain 1 is wound by the winding shaft 2 by the winding device 30, and the winding shaft 2 on which the shutter curtain 1 is wound in this way is moved from the winding device 30 to the receiving table. 120. This transfer operation is illustrated in FIG. 36, in which the main body of the forklift vehicle 180 is omitted and the forks 181 are indicated by two-dot chain lines. When this transfer operation is performed, the receiving table 120 set on the front extending portion 181C of the fork 181 is moved by the movement of the forklift vehicle 180 on the floor 34 and the lifting of the fork 181. By 30, the position below the winding shaft 2 on which the shutter curtain 1 is wound has been reached. Further, the length dimension of the receiving table 120 in the lateral direction, which is the axial direction of the winding shaft 2, is L1. The distance between the second cradle 32 and the strut 41 in the left-right direction is L2, and since L1 is smaller than L2, the cradle 120 set on the forward extending portion 181C of the fork 181 is moved to the second position. Between the post 35 of the first receiving table 31 and the supporting post 41 of the second receiving table 32, the position below the winding shaft 2 on which the shutter curtain 1 is wound can be reached.

After that, by moving the forklift vehicle 180 forward and backward, the position of the mounting member 168 arranged on the receiving table 120 in the front-rear direction is adjusted to the first supporting portion 51 of the first receiving table 31 of the winding device 30 . 12(B). After retracting the pressing means 68 attached to the shutter curtain from the driven gear 55 attached to the neck portion 10A as indicated by the two-dot chain line, the fork 181 is raised to lift the receiving table 120, whereby the shutter curtain is lifted. The winding shaft 2 on which 1 is wound is placed from the winding device 30 to the receiving table 120 between the supporting column 35 of the first receiving table 31 and the supporting column 41 of the second receiving table 32. 37, the winding shaft 2 on which the shutter curtain 1 is wound is transferred to the winding device 30 and placed on the mounting member 168. to the receiving table 120.

At least the bottom surface portion of the mounting member 168 that contacts the elevating member 134 is made of natural rubber, synthetic rubber, or the like, which has a high coefficient of friction with the metal of which the elevating member 134 is made. Even if the winding shaft 2 on which the shutter curtain 1 is wound is mounted on the mounting member 168, the two mounting half members 168A constituting the mounting member 168 move backward from the winding shaft 2. never do.

The driven gear 55 is removed from the winding shaft 2 transferred from the winding device 30 to the receiving table 120 as described above, and the pillow block 11 described with reference to FIG. 1 is arranged on the neck portion 10A. .

In FIG. 38, a forklift is used to bridge the winding shaft 2 on which the shutter curtain 1 is wound between two brackets 8 attached to the high building frame 7 shown in FIG. A state in which the vehicle 180 is driven to the installation site of the shutter device, and the fork 181 is raised to raise the receiving table 120 and the winding shaft 2 is shown with the forklift vehicle 180 indicated by a two-dot chain line.

In order to bridge the winding shaft 2 between the two brackets 8, as can be seen from FIG. The height position of the winding shaft 2 mounted on the mounting member 168 is raised to a position close to the height position where the bracket 8 is arranged, and then the operator operates the operation device described above to The vertical movement mechanism 143 provided on the receiving table 120 is driven to raise the elevating member 134 so that the height position of the winding shaft 2 mounted on the mounting member 168 is aligned with the height position of the bracket 8 . In addition, the left-right movement table 144 is moved in the left-right direction by the left-right movement mechanism 125 so that both ends of the winding shaft 2 placed on the placing member 168 in the length direction are shifted in the left-right direction to the brackets 8 . match the horizontal position of the

After that, the operator operates the operating device to drive the forward/backward moving mechanism 142 provided on the receiving table 120 to advance the lifting member 134, thereby moving the winding shaft 2 placed on the placing member 168. It is moved to the position where the bracket 8 is arranged, and the neck portion 10 of the winding shaft 2 is inserted into the concave portion 8A provided in the bracket 8 so as to open forward. By carrying out this insertion work for each of the two brackets 8, both ends in the length direction of the winding shaft 2 are horizontally or substantially horizontally bridged between the two brackets 8, and the winding shaft 2 is wound by these brackets 8. A spindle 2 is held.

As can be seen from the above description, the shutter curtain winding shaft construction apparatus according to the present embodiment includes a winding device 30 for winding the shutter curtain 1 with the winding shaft 2 and the shutter by the winding device 30. A receiving table 120 for receiving the winding shaft 2 on which the curtain 1 is wound from the winding device 30, and the receiving table 120 is set on a fork 181. When the fork 181 is lifted, the winding shaft 2 is wound. and a forklift vehicle 180 that is transferred from the device 30 to the receiving table 120 . Therefore, after the shutter curtain 1 is wound by the winding shaft 2 by the winding device 30 brought to the installation site of the shutter device, it is brought to the installation site of the shutter device, and the receiving table 120 is set on the fork 181. By raising the fork 181 of the forklift vehicle 180, the winding shaft 2 around which the shutter curtain 1 is wound can be transferred from the winding device 30 to the receiving table 120, and the forklift vehicle 180 is driven. By performing such operations as above, the necks 10 of the winding shaft 2 around which the shutter curtain 1 is wound are attached to the brackets 8 provided on the building frame 7 at two intervals in the axial direction of the winding shaft 2. It is possible to carry out the work for horizontal or substantially horizontal suspension, and for this reason, from the work for winding the shutter curtain 1 on the winding shaft 2, each neck 10 of the winding shaft 2 is attached to two brackets. A series of operations up to the operation for horizontally or substantially horizontally spanning the bridge 8 can be easily and rationally carried out.

When performing the above work, for example, the floor 186 on which the forklift vehicle 180 shown in FIG. , the height positions of both ends of the winding shaft 2 in the length direction do not match the height positions of the concave portions 8A of the two brackets 8. As shown in FIG. Therefore, in such a case, the electric motors 154 of the two pantograph mechanisms 136 arranged at the left and right ends of the receiving table 120 are separately driven and controlled by the operation of the operating device by the operator. The height positions of both ends of the winding shaft 2 in the length direction are individually adjusted by the mounting members 168 provided on each of the two elevating members 134 . After the height positions of both ends in the vertical direction are aligned with the height positions of the concave portions 8A of the two brackets 8, the lifting member 134 is advanced by driving the forward/backward moving mechanism 142 arranged on the receiving table 120. Then, the neck portions 10 at both longitudinal ends of the winding shaft 2 are inserted into the concave portions 8A of the two brackets 8, respectively.

As can be seen from the above description, in this embodiment, the two vertical movement mechanisms 143 arranged as the pantograph mechanisms 136 on the receiving table 120 can be individually driven by the operating device and the control device. The vertical support position of the winding shaft 2, which is supported by two mounting members 168 spaced apart in the lengthwise direction of the winding shaft 2 on the receiving table 120, can be individually controlled by the vertical movement mechanisms 143. By driving, it is possible to individually adjust the lifting operation of the winding shaft 2 on which the shutter curtain 1 is wound up to the height of each end of the winding shaft 2 in the longitudinal direction. This can be done while matching the height positions of the two brackets 8 .
