Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically supplying and taking out a bobbin in automatic small winding for winding a paper, a film or the like on a bobbin.

[0002]

2. Description of the Related Art Conventionally, in a paper / film winding device, an adhesive tape of a certain length is attached to the bobbin surface, and when the winding is completed, the driven side shaft of the bobbin fixed shaft is pulled out in the axial direction. The mainstream method was to manually attach a bobbin to which an adhesive tape had been attached after this. Further, this manual work has become a bottleneck and has become a barrier for a semi-automatic or automatic winding machine. In addition, when the bobbin is transferred by an arm or the like, both the empty bobbin and the wound bobbin cannot be horizontally maintained by a simple mechanism, which is a subject for study.

[0003]

SUMMARY OF THE INVENTION In order to solve the above problems, according to the present invention, when delivering a bobbin, both an empty bobbin and a bobbin after winding are maintained horizontally by a simple mechanism. An object of the present invention is to provide a bobbin supply device capable of performing

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the bobbin feeding device of the present invention will be described in detail below with reference to the drawings.

<First Embodiment> FIG. 1 is a schematic perspective view showing an embodiment of the present invention. The two columnar members 1 fixed at parallel intervals and the plate piece 2 having a U-shaped cutout are aligned so that the centers thereof are aligned at the same positions on the left and right sides of the columnar members so that the cutout 3 is on the upper side. Multiple sets are provided. Since one of the U-shapes receives the bobbin at a position where the web is not wound before and after winding, it has a radius of an empty bobbin, and the other is a position where the web is wound. Therefore, it has a radius of the diameter of the bobbin at the end of winding.

With this alone, when an empty bobbin is placed,
U having a radius of the bobbin at the end of the winding
The bobbin of the letter goes down and becomes slanted. In order to prevent this, the stopper 4 and the damper 5 are provided in the middle portion of the U-shape so that the empty bobbin becomes parallel when loaded. Further, the two columnar members 1 are equipped with a ball screw 6, a ball screw nut 7, and a motor 8 for rotating the ball screw as means for horizontally reciprocating in the longitudinal direction.

On the other hand, it is within the horizontal movement range of the two columnar members 1, has means for reciprocating up and down, and has the same shape as the U-shape provided on the two columnar members, and left and right U-shapes. Is provided with a bobbin delivery mechanism 9 which has a short distance and can move up and down inside the U-shape provided on the two columnar members. The means for reciprocating up and down is the linear motor (trade name) in the figure.
The type of horizontal reciprocating motion and vertical reciprocating motion is not limited as long as it can perform linear reciprocating motion such as a ball screw and an air cylinder.

FIG. 2 is a front view of FIG. 1, and it can be seen that the bobbin transfer mechanism 9 is located inside the two columnar members 1. From this state, the U-shaped arm 10 of the bobbin delivery mechanism 9 is lifted to receive the bobbin 11, and the bobbin is taken up by the bobbin chucking portion for winding the web around the bobbin located above the extension.

FIG. 3 is an explanatory view of a portion of the plate piece 2 having the U-shaped notch 3 on the left side surface of the present invention. In this example, the bobbin 11 is received on the outside of the upper portion of the collar having the fine groove.

FIG. 4 is an explanatory view of a portion of the plate piece 2 having the U-shaped notch 3 on the right side surface of the present invention. In the drawing, the empty bobbin 11 is received by the damper 5.
As shown by the dotted line, the state where the web is wound up becomes heavy and cannot be supported by the damper 5, as indicated by the dotted line.
It will be received by the notch 3 in the shape of a letter. At this time, the damper 5, the stopper and the notch 3 are provided in such a positional relationship that the core of the bobbin does not change.

FIG. 5 is an explanatory view of a bobbin chucking portion for winding the web around the bobbin. The U-shaped bobbin 11 provided on the two columnar members stops at the position of the U-shaped arm 10 of the bobbin transfer mechanism 9. After that, the U-shaped arm 10 of the bobbin transfer mechanism 9 moves up to receive the bobbin 11, and further moves up to bring it to the bobbin chucking portion. Then, the air cylinder 12 pushes the air cylinder shaft 13 from the right side to chuck the bobbin 11 on the drive shaft 14, and the U-shaped arm 10 of the bobbin transfer mechanism 9 descends. After this, the web is wound up, and when a predetermined amount has been wound up, the U-shaped arm 10 of the bobbin delivery mechanism 9 rises again, receives the bobbin 11 wound up on the web, and descends to form the two columnar members. The bobbin 11 wound with the web is delivered to the U-shape provided. In this way, the web can be successively wound small around the bobbin 11 set in the U-shape provided on the two columnar members.

<Embodiment 2> FIG. 6 corresponds to a second aspect of the present invention in which a plurality of pairs of columnar members 21 are directly provided with U-shaped notches 3 to form a cassette 22. The means for moving the cassette in the longitudinal direction is provided with a connecting shaft 26 on the motor 25, and a plurality of pinions (two in FIG.
It is provided). A rack 24 is provided on the cassette. The arm 2 of the air cylinder 27 is used as means for moving the cassette in a direction perpendicular to the longitudinal direction.
8 is expanded and contracted to adjust the position of the columnar member 21.

FIG. 7 is an explanatory view of the rack and pinion portion of FIG. 6 viewed from the A direction. Since there are two pairs of columnar members 21, even if the cassette 22 is moved to the position of the bobbin delivery mechanism 9 shown in the first embodiment, the rack 24 is not moved by the pinion 2.
Two pinions 23 are provided so as to engage with 3.

FIG. 8 is an explanatory view of the air cylinder 27, which is means for moving the cassette in the direction perpendicular to the longitudinal direction, as viewed from the direction A. The arm 28 of the air cylinder 27 is moved left and right to align the rack 24 portion of the cassette 22 with the pinion 23.

The number of the cassettes 22 is 2 rows × 20 units, which is most suitable in consideration of portability, moving distance to the transfer mechanism, and the like. It is also possible to provide a guide on the side plate of the cassette to facilitate stacking of the cassettes. In this way, material handling such as palletizing is possible and effective utilization is possible. As the material of the cassette, metal, resin, wood or the like is used, but resin is preferable from the viewpoint of weight.

[0019]

When the bobbin feeding device of the present invention is used,
Both when the bobbin is empty and after it is wound up, the bobbin can be handed over and conveyed while keeping the horizontal state, which reduces troubles. Also, by automating the bobbin replacement,
The tact time for bobbin replacement has been reduced, and it has become possible to operate from one machine to two machines per person, resulting in labor-saving effects. In the invention of claim 2, the number of bobbins can be increased, and since it is a cassette type, it can be attached and detached, so that it can be effectively used in common in other steps.
