Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a binding machine for binding coils formed by spirally winding iron wire, for example, to prevent the load from collapsing. The present invention relates to a body wrapping machine for winding and binding the body of a bundled coil formed by binding a plurality of locations at predetermined angles in a direction with a binding material covering the inner and outer surfaces of the coil.

Prior Art A conventional bundled coil 50 is shown in FIGS. 7 and 8. That is, for example, there are multiple locations at predetermined angle intervals in the circumferential direction of the coil 51 formed by spirally winding iron wire (in the example, three locations at 120 degree intervals).
are bound together with a binding material 52 extending over the inner and outer surfaces of the coil 51. According to such a bundled coil 50, when the coil 51 becomes loose due to vibrations during transportation work or transfer work, the binding material 52 moves as shown by the imaginary line in FIG. The angular bundling becomes disordered and the load collapses. In order to solve these problems, a body binding machine has been proposed, for example, as disclosed in Japanese Patent Publication No. 56-49211. This traditional format is
The bundled coil-shaped object is supported horizontally from the support means,
Then, the restraining coil is rotated (rotated) around the coil axis by the support means so that one main binding strip faces the binding machine, and then the secondary binding belt supplied from the binding machine is used as the main binding belt. Layer it on the binding strip,
These overlapping parts are fixed together with rivets or the like. Then, the binding coil is rotated again by the support means, and the next main binding strip is made to face the binding machine, and the free end is in the middle of the secondary binding strip to which it has already been fixed, and the main binding strip is Fix the overlapped part. By repeating this process, the body of the binding coil is made into a sub-binding band.

Problems to be Solved by the Invention According to the conventional method as described above, the bundled coil-shaped articles to be used for body binding must be fed one by one to the support means and must be taken out after binding. Therefore, for example, when transferring to or from a nearby transport device, a corresponding transfer device is required and time is required for the transfer operation. Moreover, the bundled coil-like object is a heavy object, and the supporting means for supporting and rotating it horizontally must be large and require a large amount of power, which is uneconomical. Then, by supporting and rotating it with rollers, there is a risk of damaging the outer surface of the binding coil-like object, and furthermore, it will promote loosening of the main binding band-like object.

By the way, if you support the bundled coils vertically,
It is also possible to supply binding material by fitting a binding material guide frame that is open on the inside, but according to this method, the binding material that comes off from the binding material guide frame and moves to the outer peripheral surface of the coil during tightening is weighed down by its own weight. This may cause it to sag, and the binding position may be slightly downward. In particular, when the outer diameter of the coil is small (small diameter) with respect to the binding material guide frame, the hanging becomes large.

An object of the present invention is to maintain the bundled coils vertically supported by a hanging conveyance device.
A coil that can bind the body without loading or unloading it onto a conveying device or rotating it, and which can always face the binding machine without shifting to a fixed position, regardless of changes in the outer diameter of the bundled coil. The object of the present invention is to provide a body wrap tying machine for.

Means for Solving the Problems In order to solve the above-mentioned problems, the body wrapping machine for coils according to the present invention has a vertical guide body installed on the side of a suspension conveyance path for suspending and conveying bundled coils vertically. A movable frame body guided by the movable frame body is provided, and the movable frame body includes a binding device, a binding material guide frame that can be freely fitted to the outside of the bundled coil and is open on the inside,
a binding material receiver that is attached to the binding material guide frame and can freely come into contact with and separate from the outer surface of the bundled coil side;
An actuating device for causing contact and separation is provided.

Effects According to the configuration of the present invention described above, after the bundled coils that have been suspended and conveyed vertically are stopped facing the guide body, the movable frame body is guided by the vertically oriented guide body to move the coil axis. By moving the binding material guide frame along the bundled coil, the binding material guide frame can be externally fitted and opposed to a predetermined position in the coil axial direction of the bundled coil,
By supplying the binding material into the binding material guide frame in this state, the binding material can be surrounded on the outside of the body of the bundled coil. Next, by bringing the binding material receiver into contact with the outer surface of the coil using the actuating device, the binding material that comes off the binding material guide frame and moves to the outer peripheral surface of the bundled coil during tightening is controlled.
The binding material receiver can support and guide the binding material from below, and then the binding material can be bound by a binding machine to perform trunk binding.

It is carried out by. A binding device 25 is disposed on the movable table 23. Reference numeral 26 denotes a binding material guide frame that can be fitted onto the bound coil 14 and is open on the inside, and is attached to the movable frame body 21 side via a holding frame 27. A binding material receiver that can come into contact with the outer surface of the bundled coil 14 side and can be moved away from the binding material guide frame 26 is provided at an appropriate location (two locations are shown in the embodiment, but the number of locations can be arbitrarily determined) of the binding material guide frame 26. There are 28. That is, the binding material receiver 28 is swingably attached via a vertical pin 29, and its swinging is performed by a cylinder device (an example of an actuating device) 30 provided between it and the holding frame 27. A tape-shaped (or linear) binding material 3 is attached to the movable frame 21.
A forced transfer device 32 and guide rollers 33 are provided for supplying and pulling back 1. Below the hanger stop position, that is, the binding position, a stabilizer 34 is provided which can be freely fitted and removed from the lower end of the vertical rod 9 and performs positioning by fitting.

According to the embodiment described above, first, the binding guide frame 26 is lowered as shown by the solid line in FIG.
The hanger 7 is transported by the hanging transport device 1, and the bundled coil 14 formed by supporting the hanger 7 is stopped at the binding position. Next, the stabilizer 34 is operated and fitted to the lower end of the vertical rod 9 as shown by the imaginary line in FIG. 1, thereby resting the hanger 7 side, that is, fixing it. Then, the movable frame body 21 is raised by the operation of the cylinder device 22, and the binding material guide frame 26 is fitted onto the bundled coil 14, and the bounding material guide frame 26 is fitted over the bundled coil 14, and the bounding material guide frame 26 is placed on the bundled coil 14 as shown in the imaginary line in FIG. 1 and in FIGS. 2 and 3. Place it opposite the corresponding location. At this time, the binding material receiver 28 is in the separated position. Next, the forced transfer device 32 is operated to feed the binding material 31 into the binding material guide frame 26. At this time, the binding material 31 is guided while being curved against elasticity, so that the supply is performed without coming off from the binding material guide frame 26. Then, each cylinder device 30 is operated, and the binding material receiver 28 is swung to bring its tip into contact with the binding material 16 as shown by the imaginary line in FIG. 2 and in FIG. 4. Note that the binding material receiver 28 may be oscillated before the binding material 31 is supplied, or may be brought into contact with the body of the coil 15. While holding the tip of the supplied binding material 31 on the binding device 25 side, the forced transfer device 3
2 is reversely operated to pull back the binding material 31.
As a result, the binding material 31 separates inward from the binding material guide frame 26, and comes into contact with the outer surface of the body of the bundled coil 14, as shown by the imaginary line in FIG. At this time, since the lower end of the binding material 31 is supported and guided by the binding material receiver 28, the binding material 31 is correctly moved to a predetermined position without hanging down. By further operating the forced transfer device 32, the body is tightened by the binding material 31. At this time, the movable base 23 is advanced by the tightening force or by the operation of the cylinder device 24, and the binding device 25 is moved forward.

By detecting and controlling the amount of elevation on the movable frame 21 side using the elevation level detection device 40, it is possible to perform bundling at one or more preferred locations depending on the coil height.

There are various locations where the coil 15 is bound with the binding material 16, such as four locations at 90 degree intervals as shown in FIG. 6, for example.

Effects of the Invention According to the configuration of the present invention described above, after the bundled coils that have been suspended and conveyed vertically are stopped at the binding location, the movable frame is guided by the vertical guide body along the coil axis. By moving the bundled coil, the binding material guide frame can be externally fitted and opposed to the predetermined position in the axial direction of the bundled coil, and in this state, by supplying the binding material into the binding material guide frame, , the binding material can be surrounded on the outside of the body of the bundled coil. Next, by operating the binding material receiver in contact with the outer surface of the coil by the actuator, the binding material that comes off the binding material guide frame inwardly during tightening and moves to the outer peripheral surface of the bundled coil is removed from the bundle. The binding material can be supported and guided from below by the material receiver, so that the binding material that has come off the binding material guide frame does not sag due to its own weight, and the outer peripheral surface of the bundled coil at the desired binding position is prevented. can be contacted correctly, and then
By tightening and tying the coils using a tying machine, the bundled coils can always be reliably tied at the desired position regardless of the outer diameter of the coils. In this way, the bundled coils can always be reliably bundled into the body without being loaded or unloaded while being supported vertically on the suspended conveyance device, making it possible to eliminate the need for a special transfer device and to improve the transfer speed. This eliminates the need for additional time and improves efficiency. Moreover, the body binding can be performed without rotating the bundled coil-like object, making it possible to eliminate the need for a rotation support means, and to prevent damage to the outer surface and occurrence of loosening.
