DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding an embossed tape (hereinafter referred to as "tape") sent from a molding machine onto a reel and automatically replacing the reel after the winding is completed.

[0002]

2. Description of the Related Art Conventionally, tapes sent from a molding machine are:
The end is picked up by a person and inserted into the tape insertion slot through the slit in the side plate of the reel, then wound on the reel.After winding is completed, the rear end of the tape is cut, and the reel is replaced manually. Was.

[0003]

However, such a conventional apparatus has the following disadvantages. 1 The tape is manually inserted into the tape insertion slot, and the tape is wound up. 2. When inserting the tape into the tape insertion slot, problems such as breaking the tape or winding the tape with insufficient insertion occurred due to individual differences and the degree of fatigue of each person. 3. In the conventional insertion and take-up automatic machines, since the opening size of the tape insertion slot of the reel is large and deep, usable reels are limited to special ones.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and automatically inserts the leading end of a formed and fed tape into a tape insertion slot of an empty reel to complete winding. It provides a device that automatically replaces the reel with a new empty reel, requiring no human intervention.This is a drawer that pulls out the embossed tape by holding the leading end, a tape insertion slot of the empty reel that is attracted to the tape winding shaft. After inserting the leading end of the tape into the insertion plate and rotating the tape winding shaft to complete the winding of the tape, crush the embossed part at the rear end of the tape and cut the tape at the part in front of the crushed embossed part The reeling machine that has completed winding is stored in the take-up reel storage shaft, a new empty reel is taken out from the empty reel mounting shaft,
The gist of the present invention is a reel winding and reel exchanging device for an embossed tape, comprising a reel transfer arm to be attracted to a tape winding shaft.

[0005]

In the apparatus of the present invention as described above, the leading end of the tape is clamped by a drawer, pulled out to the tape insertion slot of the reel, inserted into the tape insertion slot with the insertion plate, and the reel is rotated to take up the tape. When the winding is completed, the tape is cut by the flattening / cutting device, and then the reel that has been completely wound by the reel transfer arm is mounted on the winding storage shaft, and a new empty reel is mounted on the tape winding shaft. is there.

Hereinafter, the present invention will be described in detail with reference to FIGS. FIG. 1 is an explanatory view of a reel winding and reel changing device for a tape according to the present invention. As shown in FIGS. 1 (a) and 1 (b), a tape 1 continuously fed from a molding machine (not shown). Of the embossed portion 2 was crushed by the flattening / cutting device 3 at the position A, and at the same time, the tape 1 was cut in front of the crushed embossed portion, and the flattening / cutting device 3 was retracted to the position B and jumped out. The leading end 4 of the tape is turned 90 ° from the horizontal direction to the vertical direction, and is held by the drawer 6 in the insertion device 5 coming onto the tape 1 and moved in the horizontal direction to move the tape insertion port 8 of the empty reel 7.
Pull up. Then, as shown in (c), the upper plate 9 of the drawer 6 is raised to release the tape tip 4, and at the same time, the insertion plate 10 is lowered to insert the tape tip 4 while bending the tape tip 4. Then raise it. As a result, the leading end 4 of the tape is held so as not to come out of the tape insertion opening 8. A rotary actuator, an air cylinder, an electromagnetic cylinder, or the like is used for driving the flattening / cutting device 3 and the insertion device 5.

When the insertion of the tape is completed, as shown in FIG. 2, the tape winding shaft 11 holding the side wall of the empty reel 7 by vacuum is rotated by a motor to wind the tape 1 and a predetermined amount is wound. 1A, the flattening / cutting device 3 is returned to the position A, and the embossed portion 2 at the rear end of the tape wound on the reel is crushed, as shown in FIG. The tape 1 is cut at a position in front of the crushed embossed portion 2, and the flattening / cutting device 3 is retreated to the position B again,
The remaining tape tip 4 is protruded from the flattening / cutting device 2.

[0008] Next, the side wall of the reel 12 that has been wound up is placed on a first reel transfer arm (hereinafter referred to as an arm) 13.
Then, the suction pad 14 at the tip of the arm is moved in the direction of the turning axis of the arm to perform vacuum suction, and the arm 13 is turned to store the wound reel 12 on the take-up reel storage shaft 15. At the same time, the second arm 16 is turned to push out the empty reel 7 attached to the empty reel attachment shaft 17 with the empty reel pushing member 18 and to cause the suction pad 19 to vacuum-suck.
The arm 16 is turned to rotate the empty reel 7 to the tape winding shaft 1.
Then, the first tape insertion process is started again.

The material of the drawer 6 is made of iron or aluminum, and is knurled or a rubber plate is attached to prevent slippage when the tape is pulled out. In addition, the insertion plate 10
Is made of iron and made the surface slippery by Teflon processing, etc.
When the insertion plate 10 is pulled out after the tape insertion, the tape tip 4 is prevented from coming out of the tape insertion opening 8 together with the insertion plate 10. Examples of the material of the suction pad include rubber.
Silicone rubber is more stable and preferred. The arm is turned by a rotary actuator or a motor. The take-out of the reel may be performed by an air chuck if the positioning is reliable.

[0010]

Since the steps from tape cutting to winding and reel replacement are performed unattended, there is no individual difference in work, and trouble such as tape breakage can be solved.
