2. Description of the Related Art So-called slinging work in which articles such as rods and pipes are hung and placed at a predetermined position or picked up from the predetermined position is called a rope, wire or the like suspended from a crane in a ring shape. A sling worker who moves to an article by operation and waits near the article hangs the rope, wire, etc. on the end of the article, then lifts the article by a crane operation and moves it to a predetermined position, and there Remove the ropes, wires, etc. by hanging them down and placing them on the support bar that is generally called "Ringi".
Furthermore, a support rod was further arranged on the article thus placed, and the next article was placed on the support rod by the same crane operation and slinging work as described above. . In addition, when taking out the articles stacked in this way, the slinging work and the crane operation are carried out in the same manner, and every time one article is taken out, the slinging worker removes the supporting rods remaining after that. It was

However, the slinging work of hanging and picking up an article at a predetermined position or lifting and picking it up from that position requires a slinging operator and is extremely dangerous work. Therefore, in order to solve this problem, a device has been proposed which can automatically perform a slinging work without requiring a slinging worker. Such automatic slinging apparatus is disclosed in, for example, Japanese Patent Laid-Open No. 3-56393, Japanese Utility Model Laid-Open No. 63-154585, and Japanese Utility Model Laid-Open No. 63-2.
It is disclosed in Japanese Patent Publication No. 0701.

JP-A-3-56393 and Japanese Utility Model Laid-Open No. 63-
The automatic slinging device disclosed in each publication of No. 154585 mounts a pair of automatic slinging devices on a beam long in the lateral direction that can be suspended and moved by a crane or the like so that they can approach and separate from each other along the beam longitudinal direction. Each sling is provided with a pair of hanging arms arranged in a direction transverse to the longitudinal direction of the beam and capable of approaching and separating from each other, and a string-like body for slinging, such as a rope, a wire, or a chain linearly passed between the arms. It is of the type

The one disclosed in Japanese Utility Model Publication No. 63-20701 is a pair of droops in which the parts of each automatic slinging device are arranged in a direction transverse to the longitudinal direction of a beam supporting the slinging device so that they can approach and separate from each other. An arm and a string-like body for slinging, such as a non-bend back chain, which is supported so as to be able to move in and out of one hanging arm, is linearly extended from the one arm to the other hanging arm, and can be connected to the other arm. It is of the type provided.

Although the automatic slinging apparatus has been developed in this way, on the other hand, in the slinging operation of the article, the operation of handling the supporting bar is still performed in order to support the article with the supporting bar as described above. Needed,
In addition, since it is necessary to have sufficient space for all or part of the worker's body to enter, when transporting such articles by ship, vehicle, etc. or when storing them in a warehouse, There was a problem that the space for loading and the storage space in the warehouse could not be fully utilized.

Therefore, a multi-tiered shelving apparatus has been proposed which is capable of holding an article to be slung in a plurality of stages without the need for a conventional supporting rod or manpower. In this multi-tiered shelving device, when an article is placed on the lower shelf of the multi-tiered article support shelves, the upper shelves placed at the storage position are automatically fed out and the articles are taken out from the upper shelves. And the shelf automatically retracts to the storage position. For example, Japanese Patent Publication No. 49-96.
59, Japanese Examined Patent Publication No. 54-29796, JP-A-59-45.
28, JP-A-60-132804, JP-A-61-2.
7814, Japanese Patent Laid-Open No. 53-61874, Japanese Patent Publication No. 3-2
Publications such as 1427 teach this.

[0008]

Aside from the automatic slinging apparatus described above, the multi-level shelving apparatus still has the following problems. That is, each of the conventional multi-stage shelving devices has a problem that the structure is extremely complicated and the manufacturing cost is too high. The reason is that a drive device for moving the support shelves of each stage between the article support position and the storage position must be provided for each support shelf. Further, among the above-mentioned publications, Japanese Patent Laid-Open No. 53-6187
In multi-stage shelving devices disclosed in publications other than Japanese Patent Publication No. 4 and Japanese Patent Publication No. 3-21427, the support shelves stored in the apparatus frame in an upright position are lowered by the upper end of the support shelves to rotate the articles. Since it is configured to project laterally to the support position, the protruding and retracted support shelves are stored in the equipment frame in a standing posture, which inevitably increases the height of the equipment as a whole, and as a result, ships, vehicles, and warehouses. In addition to the problem that effective use of space is hindered, there is a problem that large shock, vibration and noise are generated when the support shelf is lowered and raised, and the support rack is supported due to this shock and vibration. There is also the fear that the intended item will fall.

In view of the above, the present invention provides an article support device capable of holding an article to be sled in a plurality of upper and lower tiers with a simplified structure and at a low cost, so that the article support arm of the article support device can be retracted to its retracted position. And an article support arm driving device for moving between the article support position and the article support position,
A first object of the present invention is to provide a slinging apparatus that is less expensive than the case where such a driving device is provided for each article supporting arm in the article supporting apparatus.

Further, the present invention provides a simple structure as a whole by a combination of an article supporting device which can safely hold an article to be sled, has less impact and vibration, and has a simple structure and is inexpensive, and the sling apparatus. A second object is to provide a slinging processing device that can be manufactured at low cost.

Further, the both slopes are provided when the article support arm in the retracted position is hooked by the article support arm hooking member to rotate to the article support position, or the article support arm in the article support position is hooked by the hooking member. When it is rotated to the retracted position with, from the time of its rising motion to the middle, the hooking member moves in an arc so as to gradually approach the rotation center of the article support arm, and therefore the rotation resistance moment gradually increases. In the meantime, the resistance from the arm supporting surface is reduced, and the article supporting arm can be smoothly rotated.

[0017]

The slinging apparatus according to the present invention is entirely suspended from the crane at the beam portion, and is arbitrarily moved up and down and horizontally moved to the slinging target article waiting in any place. Then, a pair of slings are engaged with both ends of the article, and then the sling device is hoisted while supporting the article, transported to a predetermined position, and hoisted.

When the articles thus hung up are mounted on the article supporting apparatus of the present invention, the mutual spacing between the pair of article supporting arm driving apparatuses in the sling apparatus is set to the mutual spacing between the left and right article supporting arm groups in the article supporting apparatus. Adjust accordingly. Further, in each article support arm driving device, the lateral arm is raised to the raising / retracting position. Further, in the article support device, all the arms except the lowermost arm among the plurality of article support arms at the left and right ends are retracted to the fixed frame.

The first article hung by the sling device is
The article supporting device is hung between a pair of front and rear fixed frames, and placed on the left and right lowest article supporting arms provided between the pair of fixed frames from the beginning.
Immediately after the article is placed on the lowermost support arm, or immediately before the article is placed, the article support arm, which is one step higher than the article support arm at the lowest stage, is mounted on the sling device. The pair of article support arm driving devices is rotated to the article support position. For this arm driving operation, the lateral arms for driving the article supporting arms in each article supporting arm driving device are transverse to the beam longitudinal direction, in other words, the transverse direction of the article supporting device, and The upper article support arm is arranged so as to face the retracted side, and in that state, the article support arm is lowered to the arm drive position. Thus, the article support arm hooking member of the lateral arm is arranged outside the article support arm which is still in the retracted position of the upper stage. In this state, immediately after the article is completely placed on the lowermost article support arm, or immediately before the completion of the article placement, the vertical member supporting the lateral arm in each article support arm drive device is rotated by the drive device. As a result, the article support arm on the upper side is rotated to the article support position. Thus, after the article is placed on the lowermost article support arm, the entire sling device is further lowered slightly, and then the pair of slings are removed from both ends of the article, and then the entire sling device is removed from the article support device. To prepare for loading the next item. The next article is placed on the article supporting arm at the second stage from the bottom arranged at the article supporting position as described above. The article support arm of the third stage is moved from its retracted position to the article support position in the same manner as described above, and is placed there. In this way, the articles are sequentially placed on the article support arms at the respective stages.

When the article is taken out from the article supporting device on which the article is mounted, as for the article on the uppermost article supporting arm, a pair of slings of the sling device are engaged with both ends of the article. It can be lifted and taken out without any problems. When taking out the article of the second step from the top, the mutual interval of the pair of slings in the sling device is set to be larger than the left and right length of the article, and in that state, the sling is placed near the end of the article. Place and engage the edge of the article. Thus, the article can be hoisted, but immediately before hoisting the article or immediately after the hoisting is started, the article support arm drive device moves the uppermost article support arm backward from the article support position to the retracted position on the fixed frame side. To move. Prior to this backward movement operation of the article support arm, the lateral arms in each article support arm driving device are arranged in parallel with the beam longitudinal direction, in other words, in the left-right direction of the article support device. , From that state to the arm drive position. Thus, the article support arm hooking member provided on each lateral arm is located outside the uppermost article support arm which is already empty but is still in the article support position. In this state, the vertical member supporting the lateral arm is rotated in the reverse direction by its driving device, whereby the uppermost arm is rotated backward from the article supporting position to the retracted position on the fixed frame side. Then, the article is hoisted and taken out by hoisting the slinging device.

Further, when taking out the article supported by the article supporting arm at the lower stage, the same operation as when taking out the article supported by the arm at the second stage from above is carried out from above. The empty article support arm in the second stage can be pivoted and retracted to its retracted position, and then lifted and taken out. Thus, the articles supported by the article supporting device can be sequentially lifted from the upper stage and taken out.
