Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a movable article elevator. Especially suitable for raising and lowering plate materials.

[0002]

[Prior art]

 The article elevator has a structure in which a horizontally placed article table is moved up and down by pulling a wire. The vertical drive is performed by pulling or returning the wire using a motor.

[0003]

[Problems to be solved by the device]

 Since the article mounting table is fixed horizontally, it is always a large projecting table on the side of the column for loading wide articles such as plate materials, which is inconvenient for installation, transportation, and storage. . Moreover, if the plate material is placed horizontally on the mounting table, the work is troublesome for a wide plate.

[0004]

[Means for Solving the Problems]

 The fixed column that is erected on the base is provided with a movable column that can move in the vertical direction, and the fixed column is equipped with a wire winding device. Each has a wire guide reel attached thereto, and one end of the article mounting table is hung and rotatably supported at the intermediate portion of the movable support column. One end of the wire is fixed to the other end of the mounting table, and the other end of the wire is wound from the upper guide reel of the moving support column through the lower guide reel to the winding device. An article lifter configured such that an article placing table is rotated to be raised to a predetermined position by winding, and a moving column is further raised by winding a wire.

[0005]

[Action]

 In the case of the elevator according to the present invention, when the article is lifted, a wire may be wound up to raise the article placing table rotatably attached to the moving support column while rotating, and the placing table is moved to a predetermined position. The movable support column rises while standing up, and the mounting table rises following it.

Further, when lowering the article, the reverse operation of the above may be performed. In other words, when the wire is unwound, the movable column lowers to a predetermined position, and then the article mounting table rotates and hangs down to its original state. It should be noted that the article placing table hangs down while rotating from the raised state because the center of gravity of the article placing table is tilted in a direction that hangs down from the vertical direction of the rotation axis, so that the rotational force acts on the rotation axis. is there.

【Example】

 The drawings show embodiments of the present invention. FIG. 1 is a front view, partly in section, showing a state when the article elevator according to the present invention is lowered. Reference numeral 1 is a base, and 1a is a height adjusting tool. On this base, a rectangular cylindrical fixed column 2 is erected. The column is inserted into the receiving groove 1b having substantially the same shape and can be inserted and removed. The lower end of the column may be directly fixed to the base by welding, but it is convenient for transportation and storage if it can be separated from the base.

Reference numeral 3 denotes a movable column, which is a rectangular cylinder and is provided inside the hollow of the fixed column so as to be vertically movable. The lower end of this strut is supported on the base, and the upper end projects above the fixed strut. The movable column may be supported by the fixed column, and may be configured to be supported in parallel with the fixed column, as long as it can be driven while being guided during vertical movement.

Reference numeral 4 is a wire winding device provided on the fixed column. Reference numerals 5 and 6 are wire guide reels attached to the upper and lower portions of the moving column. Reference numeral 7 denotes an intermediate portion of the movable column, that is, an article mounting table whose one end is rotatably supported between the upper and lower guide reels and is supported in a suspended state. Reference numeral 8 denotes a wire, one end side of which is fixed to the other end of the article mounting table, and the other end of the wire is attached to the winding device through the above-mentioned upper guide reel and the lower guide reel and wound. . Reference numeral 7a is a base, and 7b is an arm, one end of which is fixed to the base and the other end of which is rotatably supported by the mounting pieces 3a, 3a. Reference numeral 9 is a wide plate-like article, which is held vertically and placed on the base.

FIG. 2 shows a normal state in which the wire 8 is wound by the handle 4 a of the winding device 4 so that the article mounting table rotates and rises to move to the position of the upper end of the moving column 3. . In other words, the article mounting table is erected and the arm 7b comes into contact with the stopper 3b of the movable column, and the rotation thereof is stopped. The arm of the article mounting table or the base may be brought into direct contact with the moving column to stop the rotation thereof.

When the wire is further wound from this state, the force acts on the guide reel 6 to raise the moving support column 3. In other words, the article mounting table 7 is moved up following the support column. FIG. 3 is a front view of the state.

FIG. 4 shows details of the article mounting table. A pair of arms 7b, 7b are attached to both sides of a substantially L-shaped base 7a for supporting an article such as a plate material 9, and the other end of the arms is rotatable with respect to the mounting pieces 3a, 3a of the moving support column 3. Is supported by. Further, an arm 7b is attached to the central portion of the base 7a, and the other end of the arm is rotatably supported by a mounting piece 3a of the movable column. However, one end of the wire 8 is fixed to the base mounting portion of the arm. Therefore, when the wire is pulled, a pulling force acts on the arm 7b to rotate the arm. The fixed position of the wire can be designed so that the base is rotated by the rotation of the arm. An auxiliary arm for supporting the base may be set appropriately.

FIG. 5 shows a principle diagram of the winding device 4. Various structures are conceivable, one of which is shown. Gears A, A ', B, B'and worm gears C, C'are incorporated in the case 4e. 4a is a handle and 4c is a wire winding roller. When the handle 4a is rotated, the gear A rotates via the shaft, and the gear A'of the pair rotates. Further, the gears B and B'rotate via the shaft. Furthermore, the take-up roller 4c is rotated by being transmitted to the worm gears C and C'through the shaft. Therefore, the wire 8 can be wound. 4d is an insertion axis of a commercially available electric drill. This is linked to the shaft of the worm gear. When the tip of the drill is inserted into the insertion shaft and the electric drill is rotated, the worm gears C and C'rotate and the winding roller 4c rotates. This device can be electrically or manually wound. Of course, either one may be used.

It will be understood that, next, in order to lower the article mounting table, the reverse procedure of raising the article mounting table may be taken. When the handle 4a is turned in the opposite direction, the wire is loosened, and the moving column is lowered and stopped at a predetermined position. When the wire is further loosened, the article mounting table rotates and descends. As described above, since the article placing table has the center of gravity on the side where the article placing table falls when the article placing table is in the upright position, it gradually descends when the wire is loosened.

Although the embodiments of the present invention have been described above, those skilled in the art can fully understand that there are many design changes within the scope of the technical idea.

【effect】

 The article elevator according to the present invention is very convenient for vertical movement of a plate or the like because the article table is configured to rise while rotating and then to rise in a straight line, unlike the conventional one that vertically moves. It does not take up space when not in use. It has a more compact structure and is highly practical.
