Description

[Detailed description of the invention] The present invention relates to automatic storage equipment for yarn articles.

One step in a silk mill is the process of spinning yarn and winding it onto a bobbin, and the process of inspecting the wound yarn (spin bobbin).

The former process is becoming increasingly automated through mechanization24.
In contrast to the time-based operation, the latter relies on the judgment of female workers to sort out whether the bobbins are good or bad, so they can only work for a limited time each day. For this reason, it was necessary to temporarily store the bobbins, so the bobbins were placed on a pallet, which was then placed on a trolley and pooled. Empty bobbins to be supplied to the winder are similarly placed on pallets and stored on carts. Therefore, the method of storing bobbins and empty bobbins as described above requires a vast storage space and a large number of carts, and it is also necessary to sort and store the bobbins by type at a bobbin collection site. However, there were drawbacks such as complicated sorting management and extremely difficult to prevent contamination with other varieties. The present invention was obtained as a result of studies aimed at eliminating the drawbacks of the conventional storage methods as described above.

That is, in the present invention, shelves having a plurality of storage spaces both vertically and horizontally are arranged across a passage, and the shelves move reciprocally along the passage to take out pallets carrying bobbins or empty bobbins to the storage space. a storage device equipped with a stacker crane that performs the storage; an incoming conveyor and an outgoing conveyor connected to the shelves; and a conveying device in which a circulation path is formed by a conveyor provided between the incoming conveyor and the outgoing conveyor. At the same time, a thread-wound bobbin is installed on the side of the transport conveyor and on the discharge conveyor side.
a device for inspecting defects, and a device for supplying empty bobbins to the pallet emptied by the inspection device on the carrying-in conveyor side, and transporting the pallet with bobbins or empty bobbins placed in the storage space of the shelf; To provide an automatic storage facility for thread articles, which allows effective use of a storage space and allows accurate and easy sorting of thread bobbins.

FIG. 1 shows a schematic plan view of one embodiment of the automatic storage equipment of the present invention, and FIG. 2 shows the status of pallets when the automatic storage equipment is transported, and will be explained based on the drawings.

Reference numeral 1 denotes a shelf having a plurality of storage spaces both vertically and horizontally, and is arranged so as to form passages at predetermined intervals.

Reference numeral 2 is a stacker crane that reciprocates on the passage between the shelves to take pallets into and out of the storage space of the shelf 1, and 3 is a pallet delivery conveyor provided at one end of one of the shelves arranged across the passage.

Reference numeral 4 designates a pallet carrier conveyor provided at one end of the other shelf, and 5 designates a transport conveyor connected to the delivery conveyor 3 and the carrier conveyor 4 to form a circulation path.

6 is a bobbin quality/defective inspection device provided on the side of the transport conveyor and on the side of the carry-out conveyor 3, and 7 is an empty bobbin supply device provided on the carrier conveyor 4j.

The storage status of bobbins and empty bobbins in the automatic storage equipment will be explained.

The thread-wound bobbin sent from a winder or the like is placed on a pallet a in the state shown in FIG.

When it is time to inspect the bobbins in the above-mentioned state, the stacker crane 2 is operated to take out the block a'' on which the bobbins stored on the shelf 1 are placed and transport it to the carry-out conveyor 3. The pallet a passed through the conveyor 5 and passed to the bobbin poppin pass/fail inspection device 6.
The bobbins were sent to the pallet to sort out good and defective products, and each bobbin was taken out from the pallet at position A7 of the inspection device 6. Move.
Next, the empty bobbin a in Fig. 2-A is again sent to the empty bobbin supply device 7 by the conveyor 5, and at the opening of the empty bobbin supply device 7, the empty bobbin is supplied to the pallet.
The state shown in FIG. 21-A changes to the state shown in FIG. 2-B, and the bullet a' on which the empty bobbin is placed is sent to the carrier conveyor 4 by the conveyor 5. The pallet a' conveyed to the carrier conveyor 4 is conveyed by the stacker crane 2 to a predetermined storage space of the shelf 1, where it is temporarily stored and sent to a winder as required. As described above, the present invention has a shelf having a plurality of storage spaces arranged across a passage, which moves reciprocally along the passage to deliver pallets carrying bobbins or empty bobbins to the storage space. A circulation path is formed by a storage device equipped with a pick-up crane, a carry-in conveyor and a carry-out conveyor connected to shelves arranged across the passage, and a transfer conveyor provided between the carry-in conveyor and the carry-out conveyor. In addition to being composed of a conveyor device,
A device for inspecting whether the bobbins are good or bad is installed on the carry-out conveyor, and a device for supplying empty bobbins to the pallet emptied by the inspection device is installed on the carrier conveyor side, and the storage space of the shelf is equipped with a device for inspecting whether the bobbins are good or bad. By transporting and storing pallets on which empty bobbins are placed, the following effects are achieved.

(b) Pallets with empty bobbins placed on them are always stored on a shelf, so they can be supplied to the winding machine at any time.
Fully automated operation of the winder side for 24 hours can be made possible.

(b) Since the bobbins and empty bobbins are stored in pallets on each shelf, it is possible to easily manage the types of each thread and the type of empty bobbins.

(c) Using empty pallet a, a state in which an empty bobbin is placed (Fig. 2-B) and a state in which a bobbin is placed (Fig. 2-B)
Since the pallet is transported and stored using the pallet transport system (Fig. 1-C), it is possible to eliminate the need for a conventional cart for transporting pallets and a vast storage area for storing the cart.

(d) Since pallets are stored by circulating them between the shelves and each conveying device, empty pallets do not leave the field, making their management easy and making it possible to almost eliminate the need for spare pallets.
