DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel tape or the like which is processed by a press machine and then wound on a take-up reel when the comb-shaped product tape having been pressed is wound on the take-up reel. Alternatively, the present invention relates to a sampling device of a winder that collects a sample of a wound product tape.

[0002]

2. Description of the Related Art Conventionally, in a sampling device of a winding machine,
Japanese Unexamined Utility Model Publication No. 61-58914 discloses a sampling device. In the sampling device described in this publication, a feeding device for feeding a product tape, and a conveying path for a product tape to be wound on a take-up reel in front of the feeding device. And a tray disposed below the sample formation site in front of the cutter.

At the time of sampling by the above apparatus, first, the transport of the product tape is stopped, and the cutter is operated to cut the product tape.

After that, the feeding device is operated, the product tape is fed from the cutter portion by the length of the sample, and the feeding device is stopped again. During the operation of the feeding device, winding of the take-up reel is resumed, and the portion cut by the cutter with respect to the take-up reel becomes a terminal to be taken up by the take-up reel, and a product tape is wound. Will be fully wound.

[0005] After the feeding device is stopped, the cutter is operated again to form a sample, and the sample is dropped on the tray and sampled.

Thereafter, the feeding device is operated to convey the product tape to a new take-up reel, and the take-up is resumed.

[0007]

However, in the conventional sampling apparatus, when the sample falls on the pan, the sample may be caught around the cutter and may not enter the pan.

Further, even if the sample falls into the tray, a plurality of samples are stored and mixed, so that it may be difficult to make the product tape wound on the take-up reel correspond to the sample. Yes, it was difficult to perform proper sampling.

In this case, a large number of saucers for receiving samples are prepared, and each saucer is sequentially arranged below the sample formation site, that is, at a drop position of the sample, and each sample is placed on one saucer. It is conceivable that it is stored and dealt with. However, such a configuration requires a large number of trays and a space for them, so that the number of manufacturing steps and manufacturing costs are increased, and a large space is required.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and suppresses an increase in the number of manufacturing steps and manufacturing costs, and, as a small space, properly collects a sample corresponding to a product tape to be wound on a take-up reel. It is an object of the present invention to provide a sampling device of a winder capable of performing the above operation.

[0011]

The sampling device according to the present invention operates the cutter until the comb-shaped product tape after pressing is wound from the feeding device to the winding reel. A sampling device for a winder that cuts a product tape and collects a sample, wherein an axial direction is arranged along the sample below the sample forming portion in a transport path of the product tape, and the rotation is performed intermittently. A shaft, a plurality of trays fixed to the rotating shaft, and sequentially arranged at the sample forming portion when the rotation of the rotating shaft is stopped, and extending parallel to and obliquely below the lower side in the rotating direction of the tray, And two alignment guides each having an upwardly extending stopper and being insertable into a concave portion of the comb portion of the sample.

[0012]

In the sampling device according to the present invention, the product tape is transported in advance into the concave portion of the predetermined receiving pan, and at the time of sampling, first, when one cutter is used, the product tape is removed. The transport is stopped, the transport is stopped, and the cutter is activated when the transport is stopped twice.
Predetermined distance in product tape transport direction (length of sample)
When two separated cutters are used, the two cutters are simultaneously operated when the transport of the product tape is stopped, to form a sample. The formed sample is stored in the concave portion of the tray because the concave portion of the tray is disposed in the transport path of the product tape. In addition, the product tape in front of the cut portion is wound on a take-up reel.

After the sample is formed, the rotating shaft is rotated, a new tray is placed at the sample forming site in the product tape transport path, and the tray containing the sample is placed obliquely downward on the upper portion of the alignment guide. Placed in the position. Then, the sample stored in the tray slides out of the tray, slides on the two alignment guides while inserting the two alignment guides into the recesses of the comb, and stops at the stopper of the alignment guide. Is stored.

Thereafter, the feeding device is operated, and the product tape is inserted into the new tray and conveyed to the take-up reel side. Thereafter, the above-described steps are repeated, and the sample is sequentially transferred to the take-up reel.
The book is aligned and stored on the book alignment guide.

Therefore, in the sampling device according to the present invention, since the samples are sequentially arranged on the two alignment guides, the samples are accommodated without being mixed with other samples, and correspond to the take-up reel wound up. , Can be sampled accurately.

In addition, the apparatus can be composed of about two or three trays and two alignment guides arranged on the rotating shaft, in addition to the feeding device and the cutter, thereby increasing manufacturing man-hours and manufacturing costs. It can be configured with a small space while holding it down.

When the sample S is aligned and stored on the alignment guides 82 and 83, it is detected that the photoelectric switch 84 is full, and the control device 38 stops the operation of the feeding device 30. Then, take out each sample S,
For example, it is attached to the corresponding take-up reel R.

The sample S may be a sample of the product tape W wound around the take-up reel R after being sampled, or a sample of the product tape W fully wound around the take-up reel R at the time of sampling. It may be appropriately attached to a predetermined take-up reel R according to the state of press working.

As described above, in the sampling device M1 of the embodiment, since the samples S are sequentially arranged on the two alignment guides 82 and 83, they are accommodated without being mixed with other samples S, and are taken up. In accordance with the take-up reel R, sampling can be performed accurately, and the same effects as described in the section of the operation and effect of the invention described above can be obtained.
