Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a bundle discharging device for sending the bundle to the next process in a bundle collecting and binding machine for collecting and binding electric wires in bundles. It is.

[Prior Art] One method of shipping electric wires is a bundling method in which the electric wires are wound into a hollow donut shape.

The bundled electric wires are then bound in four directions with binding cords by a bundler and tying machine so as not to lose their shape.

FIG. 1 shows an example of a conventional bundle discharging device for sending a wire bundle to the next process in a bundle collecting and binding machine. As shown in the figure, in the conventional bundle discharging device, an arm 1 is held by an arm holder 2 so as to be rotatable via a rotating shaft 3, and is normally in a position where it pushes a bundle 4 of electric wires etc. by its own weight. , when the arm holder 2 moves above the bundle 4 in the direction opposite to the discharge direction Q of the bundle 4, as shown by the arm movement curve P indicated by an arrow in the figure, the arm 1 comes into contact with the bundle 4, so that the arm 1 is lifted and moved about the rotating shaft 3 as indicated by the arrow in the figure. The bundle discharging device configured in this manner does not require any special additional power to lift the arm 1 and has the advantage of a simple structure, but on the other hand, since the bundle 4 and the arm 1 come into contact, the bundle 4 may be damaged or deformed. There were drawbacks such as.

FIG. 2 shows another example of the bundle discharging device of the bundle collecting and binding machine. As shown in the figure, this device is formed of a lifting arm 6 that lifts and lowers the arm itself by a lifting device 5 using power such as air or electricity to prevent the arm from coming into contact with the bundle 4. This is what I did. In this case, the lifting arm 6 does not come into contact with the bundle 4, but it is necessary to add a lifting device 5 for lifting and lowering the lifting arm 6 to the moving arm holder, which has the disadvantage of making the structure complicated and expensive. Ta.

[Problems to be solved by the invention] The present invention was created in view of the above points,
By improving a part of the simple bundle discharging device shown in FIG. 1, it is possible to easily raise and lower the arm without adding a special lifting device as shown in FIG. 2 described above. It is an object of the present invention to provide a bundle discharging device for a bundle collecting and tying machine that makes it possible to perform the present invention.

[Means for Solving the Problems] That is, the present invention includes an arm holder and an arm that are driven in the direction of discharging the bundle and the opposite direction to discharge the bundle of electric wires, and the arm that discharges the bundle is In the bundle discharging device of the bundle collecting and binding machine, the bundle discharging device has a lifting means for moving the arm without contacting the bundle when moving in the opposite direction, wherein the lifting means is rotatably attached to the arm holder. an attached shaft, the arm fixed to one end of the shaft and normally holding the bundle in a position to push the bundle by its own weight, a ring fixed to the other end of the shaft, and a ring installed parallel to this ring. and a rotatable lever having a pin and a roller that rotates the ring via a guide cam provided at a predetermined position near the bundle when the arm moves in the opposite direction, and raises and lowers the ring. The lifting means is characterized by a shaft rotatably attached to the arm holder, and a position fixed to one end of the shaft and usually pushing the bundle by its own weight. an arm held by the shaft, a ring fixed to the other end of the shaft, and a guide cam installed in parallel with this ring and placed at a predetermined position near the bundle when the arm moves in the opposite direction. It is made up of a rotatable lever with a pin and a roller that rotates the arm and raises and lowers the arm.

[Example] The present invention will be further described below based on the illustrated example. FIG. 3 shows an embodiment of the present invention. It should be noted that the same parts as in the prior art have been given the same reference numerals, so their explanation will be omitted. In this embodiment, the elevating means includes a shaft 3a rotatably attached to an arm holder 2, an arm 1 fixed to one end of the shaft 3a and normally held in a position to push the bundle by its own weight, and a shaft. The ring 7 is rotated via a ring 7 fixed to the other end of the arm 3a and a guide cam 8 arranged in parallel with the ring 7 and provided at a predetermined position near the bundle when the arm 1 moves in the opposite direction. , a pin 9 and rollers 10 that raise and lower the arm 1
It is possible to obtain a bundle discharging device for a bundle collecting and tying machine which is formed with a rotatable lever 11 having a rotatable lever 11 and which makes it possible to easily raise and lower the arm 1.

That is, one end of a rotatable shaft 3a was held by a moving arm holder 2, and the arm 1 was fixed to this shaft 3a so as not to rotate. A lever 11 that can freely rotate around the shaft 3a is held at the other end of the shaft 3a, but a pin 9 is provided on the shaft 3a side of the lever 11 so that when the arm holder 2 moves in the opposite direction to the ejection direction. It was made to hang on a ring 7 fixed to the shaft 3a. By doing this, when the arm holder 2 moves in the direction of the arrow A in the figure (the direction opposite to the bundle ejection direction), the roller 10 provided at the other end of the lever 11 is placed on the guide cam 8. The pin 9 provided on the lever 11 rotates the ring 7 upward, and the shaft 3a and the arm 1 fixed to the shaft 3a similarly rotate in the C direction. This will cause arm 1 to rise.

Therefore, the guide cam 8 is placed at the position where the bundle is placed.
, so arm 1 can be moved without touching the bundle.
can be passed. After passing through the bundle, the lever 11 is returned to its original position by the guide cam 8, and the arm 1 is lowered by its own weight until it hits the stopper 12, that is, to the normal position for pushing the bundle.

When the arm holder 2 moves in the bundle ejection direction, that is, in the direction of arrow B in the figure, the lever 11 is rotated by the guide cam 8 in the opposite direction to the arrow C in the figure, as in the case described above, but the pin 9 is rotated by the ring. 7, the arm 1 fixed to the shaft 3a does not rotate and can discharge the bundle.

In this way, according to this embodiment, the arm 1 can be lifted upward when passing through the bundle, that is, when moving in the direction A opposite to the direction in which the bundle is discharged, and when the arm 1 is moving in the direction B, which is the direction in which the bundle is discharged. The arm 1 can be lowered downward, but the arm 1 can be lowered without adding lifting equipment such as air or electricity as in the past.
Arm 1 can be raised and lowered.
can be easily lifted and lowered. Additional devices include a ring 7, a guide cam 8, and a lever 11.
Since it is small and simple, it can be easily applied to existing equipment.

Although the guide cam 8 is trapezoidal in this embodiment, it is not limited to this shape, and its shape may be determined depending on the bundle of objects, and its height, length, etc. may be adjusted when used over a wide range. Just make it possible.

Furthermore, in this embodiment, the bundle of electric wires is used as an object, but it goes without saying that the present invention is not limited to this.

[Effects of the invention] As explained above, the bundle discharging device of the bundle taker of the present invention does not require the addition of special elevating devices such as air or electricity as in the past, and can be made using simple parts such as rings, cams, levers, etc. By adding , the arm can be moved up and down easily, and it has the effect of being easy to apply with a small modification of the conventional device.

Further, since the arm moves up and down, the wire bundle and the arm do not come into contact with each other, so the wire bundle is not damaged or deformed, and its practical value is very great.
