Description

TECHNICAL FIELD The present invention relates to a cross roll storage device for a loom.

2. Description of the Related Art In recent years, in the weaving factory, due to the problem of labor shortage and the demand for labor saving, a series of weaving cloth rolls woven into the cloth rolls of the loom are doffed, and a series of empty cloth rolls are supplied. Attempts have been made to automate the process. At this time, prepare an empty cross roll on the trolley in advance,
In many cases, this is moved to the machine stand of the full-cloth winding cross roll. In this case, it was conventionally performed manually to transfer the empty cross roll to the trolley.

Problems to be solved by the present invention However, in recent years, the demand for diversification of the market has led to an increase in the number of weaving factories equipped with a large number of weaving machines having different widths. In such a factory, there is a problem in terms of how to store cross rolls having different lengths and how to appropriately mount a desired empty cross roll on a truck for an auto doffer.

Therefore, in storing the empty cross rolls, the present invention does not simply store the empty cross rolls having different machine widths in a regular manner in the storage device, but takes special care when supplying the empty cross rolls to the storage device. However, when supplying empty cross rolls from this storage device to the bogie for the auto doffer, it is possible to automatically supply the appropriate empty cross rolls to looms of different widths. It is intended to provide the cross roll storage device.

SOLUTION: A bucket capable of accommodating a plurality of cross rolls having different lengths is supported by a pair of bucket conveyors having an outer peripheral surface thereof in a machine frame in a vertically circulatory manner. Around the bucket conveyor, an envelope cover is attached to prevent the contained cross roll from jumping out while the bucket conveyor is circulating, and the cover is provided with a cross roll supply port and a discharge port. A selection command device for selecting a desired cross roll from a plurality of cross rolls accommodated in the bucket conveyor, and a desired cross roll in response to a command from the selection command device, at a position near the discharge port of the cover. Is provided with a device for pushing out from the bucket conveyor to the discharge port.

EXAMPLE An example of an apparatus for carrying out the present invention will be specifically described with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a plurality of cross rolls A ₁ , A having different lengths in a bucket 1a on the outer peripheral surface thereof. ₂
...... This is a bucket conveyor that can accommodate A _n , and the conveyor is attached to the machine frame 6 by a chain 5 hung between the sprockets 2, 3, and 4 so that it can circulate vertically.

Reference numeral 7 denotes a motor which is a drive source of the bucket conveyor 1, and the motor is connected to the sprocket 2 via a gear transmission mechanism 8. Reference numeral 9 denotes an envelope cover that surrounds the periphery of the bucket conveyor 1 and prevents the cross roll A _n from jumping out of the bucket 1a during the circulation movement of the bucket conveyor 1. The cover is an obliquely upper side in FIG. is not open, the is formed as the supply port 9a of the cross roll a _n, outlet 9b is provided which can discharge the one by one cross roll a _n in the right central.

Reference numeral 10 is a selection command device for selecting a desired cross roll from a plurality of cross rolls A ₁ , A ₂ ... A _{n having} different lengths accommodated in the bucket 1a of the bucket conveyor 1. The device is a cross command device. The primary sensors X ₁ , X ₂ ... X _n operated by the gripping arms 21 for gripping the cross rolls arranged on the doffing cart for gripping the rolls and the buckets 1 a of the bucket conveyor 1 are accommodated. It comprises secondary sensors Y ₁ , Y ₂ ... Y _n operated by cross rolls A ₁ , A ₂ ... A _{n having} different lengths, and the selection device is a discharge port of the envelope cover 9. It is located near 9b. The number of sensors is arranged corresponding to the number of cross rolls having different lengths, and the case of three is illustrated in FIG. In FIG. 3, the primary sensors X ₁ , X ₂ ... X _n of the cross roll selection device 10 are a filler 11 rotatably supported by a shaft 12 and a proximity switch 13 for detecting the approach of the filler. When the cross roll gripping arm 21 presses the filler 11, the filler 11 rotates about the shaft 12 as a fulcrum and
The proximity switch 13 detects one end of 11 and the drive motor 7
Is configured to operate.

On the other hand, the secondary sensors Y ₁ , Y ₂ ... Y _n consist of a filler 14 rotatably mounted on a shaft 15 and a proximity switch 16, and a cross roll A _n accommodated in the bucket conveyor 1 By pressing this filler 14,
It is configured such that 14 rotates clockwise about a shaft 15 as a fulcrum, a proximity switch 16 detects this, and the proximity switch 16 operates a drive motor 18.

Reference numeral 17 is a device that receives a command from the cross roll selection command device 10 and pushes out the cross rolls A _n one by one to the outside from the circulation path of the bucket conveyor 1. The device 17 is a drive motor 18 that rotates forward and backward, It is composed of a gear transmission mechanism 19 that meshes with gears attached to the rotary shaft of the drive motor 18, and a rack 20 that meshes with these gears and that reciprocates in the horizontal direction.

An example of apparatus embodying the present invention has been constructed as described above, then the described operation thereof, the cross roll A ₁ of different advance lengths, A ₂ ...... A _n bucket conveyor 1
Is inserted through the supply port 9a opened above the cover 9 for covering. No special precautions are required for this insertion, and it is perfectly appropriate. Thus, around the bucket conveyor 1, as shown in FIG. 2, cross rolls A _n with different lengths are provided.
Is full and is in a waiting state. Now, a bogie (not shown) for cloth dough cross roll auto doffer approaches, and the pair of cross roll gripping arms 21 arranged on the bogie crosses the selection command device 10, for example, the primary sensor X ₁ . When pressed, the drive motor 7 receives the signal from this sensor X _1.
Sprocket 2,3,4 through the gear transmission mechanism 8
Is driven, the bucket conveyor 1 circulates through the chain 5 hung on the sprocket. Here, when the cross roll A ₁ having the same length as the length of the cross roll gripping arm 21 approaches the discharge port 9b of the covering cover 9, this cross roll A ₁ is the second of the selection command device 10.
Press the next sensor Y ₁ .

The pushing device 17 receives the signal from the secondary sensor Y _1.
The drive motor 18 is operated to move the rack 20 to the right in FIG. 2 via the pinion gear 19. Then, the cross roll A ₁ is pushed by the rack 20 and leaves the circulation path of the bucket conveyor 1, and is captured by the cross roll gripping arm 21.

Next, when there is a request from the loom side having a different machine width, the pair of cross roll gripping arms 21 of the carriage are adjusted by the arm width corresponding to the machine width, and the gripping arms 21 of the selection command device 10 are adjusted. Press the primary sensor X ₂ .

Then, in response to the signal from the primary sensor X ₂ ,
As with the next sensor X ₁ , bucket conveyor 1
Circulates, and the cross roll A ₂ having the same length as the cross roll gripping arm 21 presses the secondary sensors X ₁ and X _2, and as a result, the cross roll is pushed by the pushing device 17.
A ₂ is captured by the gripping arm 21.

Thus, thereafter, the cross rolls having a desired length are sequentially selected and automatically supplied to the gripping arm of the carriage.

Advantageous Effects of the Invention The present invention stores a plurality of cross rolls having different lengths in the bucket conveyor as described above, and stores the desired cross rolls so that the desired cross roll can be automatically selected from the stored cross rolls. As a result, compared to the conventional one, by simply mounting cross rolls of arbitrarily different lengths on this storage device, appropriate cross rolls can be used for the doffing cart and the machine width without manpower. As a result, it can be automatically supplied, which has the effect of contributing to factory automation of the loom factory.
