Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention involves forming a steel tape using a press, polymerizing the pressed product tape with paper tape, and winding it onto a take-up reel, and a paper tape reel. This relates to the reel cassette to be accommodated.

0002

[Prior Art] A conventional winding machine is equipped with a winding reel and a paper tape reel in the winding machine body, winds a product tape on the winding reel, and each time it becomes a finished product reel, an empty finished product reel is removed. The take-up reel was replaced, and each time the paper tape on the paper tape reel ran out, a new paper tape was attached to the paper tape reel. Each time the take-up reel is replaced, the starting end of the paper tape must be attached to the reel shaft of the take-up reel.
In the winding machine disclosed in Japanese Patent Application Laid-open No. 1234216/1984, the work of replacing the winding reel and pasting the starting end of the paper tape is performed by a changing robot that moves along the front of the machine.

0003

[Problem to be Solved by the Invention] When the work of pasting the starting end of paper tape is performed using a replacement robot, the starting end of the paper tape that is nipped by the tension device may be tilted or sometimes curved.
A problem arises in that the paper edge is not gripped by the paper edge gripping device. Moreover, even if the starting end of the paper tape is held, the starting end of the paper tape is only pressed against the reel shaft of the take-up reel, so that the attachment is not performed reliably. Also, care must be taken in selecting the adhesive; if the drying time is too long or too short, the adhesive will not bond and will peel off. Therefore, since the paper tape is not wound when the take-up reel is rotated, an operator has to check and repair the take-up reel every time the take-up reel is replaced. For this reason, workers cannot leave the winding machine for long periods of time, so there has been a demand for complete automation of the winding reel exchange.

As is well known, paper tape is not a rigid body, so it is difficult to fully automate it. Therefore, the present invention provides a reel cassette that accommodates the take-up reel and paper tape reel that were conventionally provided in a winder in a reel cassette, and replaces each reel cassette when replacing the take-up reel, thereby making it possible to automate the replacement of the take-up reel. We aim to provide the following.

[0005]

[Means for Solving the Problems] This invention provides a cassette body with a take-up reel support shaft and a paper tape reel support shaft, and also provides a paper tape guide shaft above the paper tape reel support shaft, and the paper tape guide shaft supports the take-up reel. The gist of this invention is a reel cassette for a winder, which is characterized by being disposed above the shaft.

[0006]

[Function/Effect] When the take-up reel is attached to the take-up reel support shaft, and the paper tape on the paper tape reel attached to the paper tape reel support shaft is suspended around the paper tape guide shaft and wound onto the reel shaft of the take-up reel, the paper tape The paper tape between the guide shaft and the reel shaft of the take-up reel is wound onto the reel shaft with an appropriate tension applied diagonally downward.

Therefore, by simply feeding the starting end of the pressed product tape along the paper tape between the paper tape guide shaft and the reel shaft and feeding it near the reel shaft, the product tape and the paper tape will overlap and be attached to the reel shaft. Automatically wound.

Reel cassettes are compact and lightweight, making them easy to handle.If a reel cassette moving device is attached to the winding machine, the reel cassette can be automatically replaced, making it easier to replace the take-up reel and paper tape reel. This invention can be easily automated and has a great effect in contributing to the automation of winding machines.

If the paper tape V breaks during winding, the operation of the winding machine is stopped by a detection command from the photoelectric switch 118.

[0035] The operation of the winding machine having such a configuration will be explained.

When the winding of the winding reel 28 of the reel cassette at the winding position S is completed and the finished product reel is obtained, the reel cassette moving device 60 on the reciprocating rail side is moved as described above.
are operated at the same time to move the reel cassettes 1 on the forward and backward rails 32, 33 intermittently by a predetermined interval P, and the next reel cassette 1 is sent to the winding position S.

When the reel cassette 1 stops at the winding position S, the feed roller 94 immediately operates to feed the product tape W forward, and also operates the air cylinder 42 of the reel rotation device 40 to move the drive gear 51 to the reel cassette. meshes with the gear 22 of. The starting end of the product tape W guided by the guide plates 92, 111, and 93 reaches the guide roller 9.
6, the curved guide plate 97 changes the direction downward and guides it into the guide tube 102.

When the starting end of the product tape W fed into the guide tube 102 is guided by the inclined surface 102a and approaches the outer periphery of the reel shaft 29, the reel drive motor 50 is activated to separate the product tape W and the paper tape V. is polymerized and taken up on the take-up reel 28.
I'm going to wind it up.

Polymerized tape W wound around the take-up reel 28,
As the diameter of the V increases, the rotary actuator 99 is rotated counterclockwise at a low speed in FIG. actuator 99
rotation is controlled.

When winding of a predetermined length is completed, the rotation of the feed roller 94 and the reel drive motor 50 is stopped, and the air cylinder 114 is activated to retract the product tape guide plate 111 to a vertical position, and then a pair of cutting steps are performed. Product tape W with cutter 108
Cut the end of the sample and the end of the sample at the same time.

After cutting the product tape, the reel drive motor 50 is instantaneously rotated to wind up the end portion of the product tape W connected to the cutting cart 108 to form a finished product reel. Immediately, the air cylinder 42 of the reel rotating device is actuated to move the drive gear 51 to the retracted position, and the rotary actuator 99 is rapidly rotated to move to the retracted position. The rotary actuator 99 may be rotated immediately after the feed roller 94 stops rotating.

By repeating the above automatic operation of the winding machine, the reel cassette 1 containing finished product reels is intermittently fed onto the forward rail 32, and a plurality of reel cassettes (10 in this embodiment) are sent onto the forward rail 32. ) can be stored.

The operator sets the cassette exchange table 83 at a position facing the reel cassette 1 on the forward rail 32, and
Pull out the reel cassette onto the cassette exchange table 83. The paper tape V connected to the finished product reel and the guide shaft 11 is cut and the terminal end is stuck to the finished product reel with adhesive tape. Inspect the sample and, if necessary, attach the sample to the finished product reel with adhesive tape.

[0044] Remove the finished product reel and empty the take-up reel 28.
After attaching the tape to the reel shaft, attach the starting end of the paper tape to the reel shaft 2.
Paste it on 9. The starting end of the cut paper tape is held between the guide shaft 11 and the leaf spring 54 and hangs down.
The starting end pasting work is easily performed. At this time, the state of consumption of the paper tape reel is checked, and if there is a risk that there will be insufficient paper tape for the next winding, the paper tape is replaced with a new paper tape before starting end pasting work is performed. After replacing the take-up reel 28,
Move the reel cassette 1 on the cassette exchange table 83 to the forward rail 3.
2 Push back up.

[0045] Take-up reel 28 of a plurality of reel cassettes
The replacement will be carried out sequentially. This work of replacing a plurality of take-up reels can be performed at once while the take-up reel is in operation.

The above embodiment is an example of how the reel cassette 1 is used when the product tape W is formed into an upward convex shape as shown in FIG. When winding the product tape onto the take-up reel 28, the flat side of the product tape (lower side in Figure 11)
must be wound so that it faces the reel shaft 29. Therefore, when the product tape is formed into a downward convex shape, the left and right sides of the reel cassette 1 are reversed (the take-up reel 28 is placed to the right of the paper tape reel 30) in FIG. Use it by placing it on. At this time, the reel drive motor 50 is controlled to rotate in the opposite direction to that in the above embodiment, and the cut sample falls into the sample receiving box 18 on the right side of FIG.

[0047] In the above embodiment, a winding machine was described that was used as a winding machine that automatically exchanges reel cassettes. It can also be used in winding machines where the reel cassette mounting table is fixed to the winding position on the machine stand and the reel cassette is replaced manually. In this case, the reel support shaft 2
5 (in place of the chain wheel 26), a reel drive motor 50 is provided in the column, and the clutch attached to the reel drive motor 50 is engaged with and disengaged from the clutch on the reel support shaft 25. , the reel support shaft 25 can be rotated.

[0048] In place of the leaf spring 54, the upper pipe 2
A roller may be rotatably supported on a bracket hinged to the guide shaft 11, and the roller may be placed on the guide shaft 11, or the leaf spring 54 or the roller may not be attached.
Since an appropriate winding tension is applied to the paper tape V between 1 and the reel shaft 29, it is practical. If it is not necessary to take a sample for each take-up reel, it is not necessary to provide a sample receiving box. Additionally, it is preferable to attach the product tape support shaft 55 in order to smoothly wind up the end of the product tape after cutting, but even without this, the normal product tape W is small and light, so paper tape It can be polymerized with V and wound up.
