Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a string-like spacer supply device, and in particular, the present invention relates to a string-like spacer supply device, and in particular, a string-like spacer feeding device that continuously feeds string-like spacers of a predetermined length to be interposed between the upper and lower parts of articles stacked in multiple stages. It relates to the supply device.

[Conventional technology]

Conventionally, when stacking articles in tiers, hard spacers such as wood, metal rods, plastic rods, etc. are arranged on the articles manually or mechanically, the articles are loaded on top of the articles, and then the hard spacers are placed on top of the articles. It is common practice to arrange .

[Problem that the invention seeks to solve]

In the conventional technology, each time a layer of objects is loaded, hard spacers are brought in and arranged one by one on top of the objects, resulting in poor work efficiency and the need to secure a separate storage space for the spacers. In addition, for example, when stacking completed aluminum sash window frame shapes that have been plated and painted in multiple layers on a pallet, etc., long spacers are required, but the weight of the hard spacers themselves Because of its large size, it is difficult to mechanically supply it, requiring large-scale equipment, and requiring heavy labor when done manually. Also,
In addition to requiring considerable labor and time to recover the spacers, there were other problems such as the possibility of damaging the completed shaped material due to the hard spacers.

[Means for solving problems]

The present invention was developed for the purpose of solving the above-mentioned problems and providing a string-like spacer supplying device that continuously supplies light and soft string-like spacers to a predetermined length. When loading objects in multiple stages with string spacers interposed between the upper and lower sides of the objects to be loaded on the lifting platform, the string spacers are placed opposite each other with the object loading device in between. A spacer supply mechanism and a string spacer tensioning mechanism are provided, and the string spacer supply mechanism has a spacer holding mechanism that causes an end portion of the string spacer to be fed to protrude and face the loading device. , the string-like spacer tensioning mechanism includes a spacer tensioning body whose tip part moves reciprocatingly along the upper surface of the loaded object, and which chucks the terminal part of the protruding string-like spacer at the tip part, Further, the string-like spacer supply mechanism includes a cutter mechanism that cuts the string-like spacer in a state where the string-like spacer is stretched by a tension body 9 of the spacer and placed transversely on the loaded object. This is a string-like spacer supply device characterized by being provided with.

[Effect]

The apparatus according to the present invention having the above structure operates as follows.

The spacer holding mechanism in the string-like spacer supply mechanism holds the end portion of the string-like spacer in a state of protruding to a predetermined length toward the string-like spacer tensioning mechanism.

When retreating to the left in the figure, the chuck 10 is marked P.
The spacer S is moved back to the position shown in FIG. become.

At the next point in time, the cylinder 4j of the cutter mechanism 4 is actuated to extend the rod 4i, and the connecting rod 4k that connects the rod 4i is lowered as shown in FIG. lowers the left part in the figure around the shaft 4h. In conjunction with this swing, the left operating lever 4e descends to push down the cutter lever 4b, and the right operating lever 4e' rises to raise the cutter lever 4b', thereby causing the cutter 4 to move upward.
c and 4c' form a scissor blade-like sliding contact and cut the spacer S at that position.

On the other hand, the cylinder 9c of the tension body 9 causes the rod to contract, causing the sliding rod 9b in FIG. 5 to retreat to the left in the figure. 4, the opening/closing bodies 9f, 9f' rotate about the shaft 9e to disengage the teeth 9i, 9i'.

Near the end of the cut spacer S, which is held by the holding mechanism 5, another shape material E is placed on top of the spacer S of the shape material E using a forklift or the like.
After placing the group, the mounting table Db' of the lifting/lowering loading machine is lowered by the height of the spacer and the height of the profile E, and the tension body 9 is advanced again, and the chuck 10 moves the spacer S
Check the end portion S' of the spacer, move back, and place the spacer S on the object to be loaded. Then, the spacer S is cut by the cutter mechanism 4, and thereafter, the same spacer supply process is repeated and continued. These series of driving operations are automatically controlled by a sensor (not shown) provided at an appropriate position and a control mechanism that generally uses a microcomputer.

Note that the present invention is not limited to the above configuration. For example, the spacer delivery and supply adjustment mechanism 3 is attached to the upper part of the support column 2, but depending on the location, the cutter mechanism 4 may be disposed on the upper part of the support column 2, and the delivery adjustment mechanism is attached to the lower part of the support column. They may be hung or placed side by side.

Since the cutter mechanism 4 only needs to be able to cut the spacer S, the structure may be changed in any way.

The tension mechanism B may also use a cylinder as the sliding mechanism for the sliding body. The chuck 10 can also be of an electromagnetic opening/closing type.

〔effect〕

Since the present invention is constructed as described above, it has many excellent effects as follows.

(1) The end of the string-like spacer to be supplied should protrude from the holding mechanism and face the loading device, and the tip of the tensioning body should be used to check it and pull it along the top surface of the object to be loaded. The spacer is cut by the cutter mechanism on the spacer supply side with the spacer placed transversely on the object to be loaded, and after loading the object on the upper stage, the same spacer supply process is repeated and continued. String-like spacers can be mechanically and continuously supplied at predetermined length intervals, resulting in good work efficiency.

(2) Light and soft string-shaped (paper string) spacers are used instead of rigid square or plate-shaped spacers, so (a) supplying operations do not require heavy labor and require less energy; The device can be made smaller and simpler. (b) A large amount of objects can be loaded onto pallets, etc. (c) Spacers do not take up much storage space and can be easily collected after use. (d) It will not damage the loaded items.
