  The rotary drive source 31 has a rotating shaft, and the hoisting cable 4 is connected to the rotating shaft. The rotational drive source 31 is rotationally driven so that the hoisting rope 4 can be wound and unwound. The rotational drive source 31 is driven by receiving supply of electricity, air, oil or the like, or is driven manually. As the rotational drive source 31, for example, a motor such as an electric motor, a hydraulic motor, or a pneumatic motor is used. In addition, the rotational drive source 31 of this embodiment is comprised with the electric motor.

  The rotational drive source 31 is fixed to the lower surface of the top plate 15 of the outer case 1. The rotation drive source 31 is attached to the lower surface of the top plate 15 so that the axis of the rotation shaft is parallel to the front-rear direction.

  The hoisting rope 4 is constituted by a long member such as a belt, a wire, or a chain. In addition, the hoisting rope 4 of this embodiment is comprised with the belt. The drive device 3 of the present embodiment includes a right cable 41 and a left cable 42 as the lifting cable 4. As shown in FIG. 2, the right cable 41 and the left cable 42 are connected to each other while being displaced in the front-rear direction on the rotation axis. The right cable 41 and the left cable 42 are both wound around the rotation shaft when the rotation shaft rotates in the forward direction. Further, the right rope 41 and the left rope 42 are both rewound when the rotary shaft rotates in the reverse direction while being wound around the rotary shaft.

  As shown in FIG. 1, the hoisting rope 4 includes a first end 43 that is an end portion in the longitudinal direction, and a second end 44 that is an end portion opposite to the first end 43. The first end 43 of the hoisting rope 4 is connected to the rotation shaft of the rotation drive source 31 as described above. Further, as shown in FIG. 3, a connecting hole 45 is provided at the second end 44 of the hoisting rope 4. The second end 44 of the hoisting rope 4 is connected to the fixed body 5 through the connecting hole 45. The connecting hole 45 is formed by folding the tip of the hoisting cord 4 and sewing the tip to the other part of the hoisting cord 4.

  As shown in FIG. 1, the fixed body 5 is fixed to the upper part in the outer case 1. More specifically, the fixed body 5 is fixed to the lower surface of the top plate 15 of the outer case 1. The fixed bodies 5 are respectively attached to both ends of the top plate 15 in the left-right direction. As shown in FIG. 4, the fixed body 5 includes a main body portion 50 and a pulley 57. The fixed body 5 is not limited to the top plate 15 of the outer case 1 but may be fixed to the upper portions of the left side plate 14 and the right side plate 13.

  The main body 50 includes a lateral surface portion 51 fixed to the top plate 15 and an elevation surface portion 53 that extends downward from both front and rear end portions of the lateral surface portion 51. A fixing tool insertion hole 52 is formed in the lateral surface portion 51. The lateral surface portion 51 is fixed to the top plate 15 via a fixing tool inserted into the fixing tool insertion hole 52. Each of the facing elevation portions 53 is provided with a through hole 54 that communicates with each other. As shown in FIG. 3, the shaft 55 is inserted into the through hole 54. The shaft 55 enters the through hole 54, the connecting hole 45 of the lifting rope 4, and the through hole 54 in this order, thereby connecting the second end 44 of the lifting rope 4 to the fixed body 5. A retaining pin 56 is attached to the shaft 55 inserted into the through hole 54 and the connecting hole 45.

  The pulley 57 is rotatably supported on the main body 50. The pulley 57 is attached to a pulley shaft 58 that is erected between the vertical surfaces 53 of the main body 50. The central axis of the pulley 57 is parallel to the front-rear direction. At both ends of the pulley 57 in the central axis direction, flange pieces 59 projecting radially outward (radially outward) are provided.

  As shown in FIGS. 1 and 5, a support 6 is fixed to the upper part of the elevating shelf 2. The support 6 is hung on an intermediate portion in the longitudinal direction of the hoisting rope 4 (that is, between the first end 43 and the second end 44). The support 6 is fixed to both ends of the elevating shelf 2 in the left-right direction. The support 6 includes a bracket 61 that is fixed to the upper surface of the upper plate 21 of the elevating shelf 2, and a pulley 78 that is pivotally supported by the bracket 61.

  As shown in FIG. 6, the bracket 61 includes a fixed base 62 and a pulley base 73. The fixed base 62 includes a horizontal plate portion 63, a first vertical plate portion 64, and a second vertical plate portion 68. The horizontal plate 63 has a length in the front-rear direction and a width in the left-right direction. The horizontal plate portion 63 is fixed to the upper surface of the upper plate 21 of the elevating shelf 2 via a fixing tool.

  The first vertical plate portion 64 extends upward from an end edge on the outer side in the width direction of the horizontal plate portion 63 (the outer side in the left-right direction of the outer case 1). The first vertical plate portion 64 has a height in the vertical direction and a width in the front-rear direction. As shown in FIG. 7, a guide portion 65 is provided on the outer side surface of the first vertical plate portion 64.

  The guide part 65 includes a stator 66 and a biasing element 67. The urging element 67 is urged toward the stator 66 by a coil spring or the like. As shown in FIG. 2, the guide portion 65 includes guide rails 16 fixed to the inner surfaces of the left side plate 14 and the right side plate 13 of the outer case 1, and a stator 66 and an urging element on both sides (both sides in the front-rear direction). It is attached so that it may be pinched by 67. The guide part 65 prevents the lifting shelf 2 from rattling back and forth by sandwiching the guide rail 16. The guide rail 16 has a length in the vertical direction, and is provided over the entire length of the movement range of the support 6.

  As shown in FIG. 6, the second vertical plate portion 68 extends upward from the inner edge in the width direction of the horizontal plate portion 63 (center side in the left-right direction of the outer case 1). The second vertical plate portion 68 has a reverse L-shape when viewed from the front. As shown in FIG. 5, a rotation shaft 69 is installed between the upper surface of the second vertical plate portion 68 and the horizontal plate portion 63. The rotation shaft 69 is rotatable around the vertical axis. A male screw portion 70 is provided on the outer peripheral surface of the rotation shaft 69. A screw head 71 is provided at the lower end of the rotation shaft 69. Further, at the upper end of the rotation shaft 69, a retaining portion 72 for retaining the second vertical plate portion 68 is provided.

  A pulley base 73 is screwed onto the rotating shaft 69. When the rotation shaft 69 rotates, the pulley base 73 moves in the vertical direction. That is, the bracket 61 of this embodiment is provided with a height adjustment mechanism that can adjust the height position of the pulley base 73.

  The upper plate 21 of the lifting shelf 2 is provided with a communication hole 27 at a location corresponding to the rotation shaft 69 in a state where the support 6 is fixed to the lifting shelf 2. The screw head 71 at the lower end of the rotation shaft 69 is configured to be able to rotate through the communication hole 27.

  As illustrated in FIG. 6, the pulley base 73 includes a moving plate portion 74 and a support plate portion 75. As shown in FIG. 5, the moving plate portion 74 is provided with a screw hole 76. The screw hole 76 is screwed to the rotation shaft 69. The support plate portion 75 extends upward from both ends of the movable plate portion 74 in the front-rear direction. A pulley shaft 77 is installed between the opposing support plate portions 75. The pulley base 73 rotatably supports the pulley 78 via the pulley shaft 77.

  The pulley 78 attached to the support 6 rolls on the middle part of the hoisting line 4. The pulley 78 is disposed between the second end 44 of the hoisting rope 4 and the pulley 57 of the fixed body 5. In other words, the pulley 78 is supported between the fixed end portion fixed to the fixed body 5 and the portion supported by the pulley 57 of the fixed body 5 on the lifting rope 4.

  When the rotational drive source 31 is driven, the drive device 3 having such a configuration operates as follows. When the rotation drive source 31 is driven, the rotation shaft rotates (this is assumed to be normal rotation), and thereby the rotation shaft winds up the hoisting rope 4. Then, the hoisting rope 4 moves in the longitudinal direction and raises the support body 6. As a result, the lifting shelf 2 rises.

  On the other hand, when the rotation drive source 31 is driven and the rotation shaft rotates in the reverse direction, the rotation shaft feeds the lifting / lowering line 4. Then, the lifting / lowering line 4 moves in the longitudinal direction to lower the support body 6. As a result, the lifting shelf 2 is lowered.

  The lifting and lowering storage device of the present embodiment is assembled as follows, for example. The operator fixes the driving device 3 and the fixed body 5 to the lower surface of the top plate 15 of the outer case 1. Further, the operator fixes the support 6 to the upper surface of the upper plate 21 of the lifting shelf 2.

  Next, the operator passes the second end 44 side of the lifting / lowering rope 4 connected to the rotation shaft of the driving device 3 through the upper side of the pulley 57 of the fixed body 5, and then passes the lower side of the pulley 78 of the support body 6. Pass through. Thereafter, the operator connects the connection hole 45 of the second end 44 of the hoisting rope 4 to the fixed body 5 via the shaft 55.

  In this regard, in the conventional lifting storage device, the second end 44 of the lifting rope 4 is fixed to the bracket 61 fixed to the lifting shelf 2. As shown in FIG. 8, the conventional bracket 61 is provided with a plate-shaped fixing bracket 81 instead of the pulley base 73. The fixing bracket 81 is provided with a slit-like opening 82 through which the second end 44 of the hoisting rope 4 is inserted. The connecting hole is inserted into the opening 82 through the second end 44 of the hoisting rope 4 from above. The elevator cable 4 is fixed by passing the shaft 55 through 45. The length of the fixing bracket 81 in the front-rear direction is smaller than the length of the fixing base 62 in the front-rear direction. For this reason, the insertion location of the shaft 55 must be a narrow location surrounded by the first vertical plate portion 64, the second vertical plate portion 68, and the fixing bracket 81, and an intricate back side location. Therefore, it was difficult for the operator to insert and remove the shaft 55.

  On the other hand, in the lifting and lowering storage device of the present embodiment, the through hole 54 is provided in the elevation surface portion 53 of the fixed body 5 and is provided at a place where the operator's finger or hand can easily reach. Is easy to secure a work space centering on the shaft 55 and is easy to work.

  As described above, the lifting and lowering storage device of the present embodiment includes the outer case 1, the lifting shelf 2, and the driving device 3. The outer case 1 opens downward. The elevating shelf 2 is provided so as to be movable up and down with respect to the outer case 1. The elevating shelf 2 is stored in the outer case 1 when it is raised, and can be loaded and unloaded when lowered. The driving device 3 moves the lifting shelf 2 up and down via the lifting rope 4 connected to the rotation drive source 31. An end (second end 44) opposite to the rotary drive source 31 side in the lifting / lowering line 4 is fixed to the upper part in the outer case 1. A support 6 that is hung on an intermediate portion in the longitudinal direction of the lifting / lowering rope 4 is fixed to the upper part of the lifting / lowering shelf 2. And if the lifting / lowering line 4 is wound up by the rotational drive source 31, the support body 6 will raise. Further, when the lifting / lowering line 4 is rewound by the rotation drive source 31, the support 6 is lowered.

  As described above, according to the lifting and lowering storage device of the present embodiment, the lifting shelf 2 is lifted and lowered using a structure like a so-called movable pulley, so that the end of the lifting rope 4 opposite to the drive source is lifted and lowered. It can be fixed at a location different from the bracket of the shelf 2. As a result, the workability of the worker can be improved.

  Moreover, according to the lifting / lowering storage apparatus of this embodiment, since the support body 6 operates like a so-called moving pulley, the tension applied to the lifting / lowering rope 4 becomes half the load applied by the support body 6. As a result, the torque required for the rotary drive source 31 can be reduced, and the tension applied to the lifting / lowering line 4 can be reduced without increasing the number of the lifting / lowering lines 4. Thereby, when using a motor as the rotational drive source 31, it is also possible to use a small motor with a small torque.

  Moreover, the hoisting rope 4 of this embodiment is a belt. The support 6 includes a pulley 78 that rolls on the belt, and a bracket 61 that rotatably supports the pulley 78. The bracket 61 is fixed to the lifting shelf 2.

  For this reason, the lifting shelf 2 can be lifted and lowered more efficiently, and the load on the rotary drive source 31 and the lifting rope 4 can be reduced.

  In the lifting / lowering storage device of the present embodiment, the support 6 fixed to the lifting / lowering shelf 2 includes a height adjusting mechanism. This height adjustment mechanism makes it possible to adjust the distance between the lifting rope 4 and the lifting shelf 2.

  For this reason, the raising / lowering storage apparatus of this embodiment can finely adjust the level of the raising / lowering shelf 2 easily.

  In the lifting / lowering storage device of this embodiment, the support body 6 is provided with the pulley 78, but instead of the pulley 78, a shaft-shaped member may be used. The shaft-shaped member may roll on the lifting / lowering line 4 or may be in sliding contact with the lifting / lowering line 4 without rotating. When a chain is used as the lifting / lowering line 4, a sprocket may be used instead of the pulley.
