To explain the operation of this device, the hopper 1
A certain amount of noodle band group w is supplied from the outside to the inside at regular intervals, and each noodle string group w thus supplied is supported by the receiving fittings 2b, 2b of the chain conveyor 2,
It is conveyed toward the rotary arm conveyor 3 with the movement of a and 2a.

The rotating arm transfer device 3 receives the noodle band group w reaching the transfer end of the chain conveyor 2 and transfers it to the metal fittings 3b and 3b, transfers it in an arc shape, and grasps the grasping part 4a of the rotary chuck 4 which stands by in an open state. 4b is supplied.

Subsequently, the tape feeding device 9 is appropriately moved through a supporting mechanism (not shown), and the leading end e of the binding tape t.
Is placed on the circumferential surface of the noodle band group w, and the rotary chuck 4 grasps the noodle band group w in relation to this. As a result, the tip e of the binding tape t is pressed by the tape pressing rod m and locked on the peripheral surface of the noodle band w, as shown in FIG.

After this state, the rotary chuck 4 is rotated a plurality of times in the direction of the arrow f1, whereby the noodle band w is also rotated together with the chuck 4. The binding tape t is fed by the tape feeding device 9 by the rotating force of the noodle string group w of this time.

The conveyor 7 discharges this noodle string bundle w1 to a specific location. On the other hand, the tape feeding device 9 is returned to the original position, and the same operation is repeated thereafter.

[0010]

In the conventional binding machine described above, since the binding tape is made of a resin material or the like, the temperature is high in the summer and softened, and the temperature is low in the winter. There is a phenomenon that it hardens.Therefore, if the same binding tape is used for binding, the pulling resistance given by the tape feeding device becomes too large in the summer and the elastic elongation of the binding tape becomes too large. On the contrary, in winter, the pullout resistance becomes too small and the elastic extension becomes too small, so that proper fastening force cannot be bound.

In order to deal with this, it is necessary to prepare a plurality of types of binding tapes having different performances with respect to temperature, and selectively use the binding tapes depending on the time of use, which makes the replacement of the tapes troublesome. In addition to this, there is a problem that the pull-out resistance of the tape feeding device must be readjusted each time the tape is replaced.

An object of the present invention is to provide a noodle string binding machine with a heater which can solve the above-mentioned conventional problems.

[0013]

In order to achieve the above-mentioned object, in the present invention, the binding tape imparts an appropriate pull-out resistance by the same rolling force of the noodle band group at a certain position. In a noodle band binding machine that operates so as to be drawn out through a feeding device and wrapped around a noodle band group, a tape heater that heats the binding tape to an appropriate substantially constant temperature is provided near the tape feeding device. Do like this.

According to the present invention, since the tape heater heats and holds the resin material tying tape at an appropriate temperature immediately before it is wound around the noodle strings, the tying tape can be used even in cold regions or in winter. The noodle string group is wound around the noodle string group in an optimal temperature state and appropriately stretched by its own elasticity, and the noodle string group is properly bound by an appropriate tensile force.

In carrying out the present invention, for example, the binding tape is not made of vinyl chloride or polyethylene material, and the tape heater uses the binding tape at 30 ° C to 60 ° C.
Shall be heated to any suitable temperature within the range. As a result, one type of binding tape will be sufficient throughout the year.

The tape heater is preferably formed by bending a plate material into a U-shape and fixing an electric heater to the inner surface of the frame. In this case, the binding tape passes through the inside of the U-shape frame. Eggplant According to this, the heater can easily guide the binding tape inward through the opening portion of the heater, and the heat can be easily accumulated in the frame to effectively heat the binding tape. .

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a binding tape t is appropriately and substantially constant between the tape supporting device 8 and the tape feeding device 9 of the conventional binding machine described with reference to FIG. Tape heater 10 for heating to temperature
Is specifically provided as follows.

That is, as shown in FIG. 3, the tape heater 10
Fixes the plate-shaped electric heater 11 to the inner surface of the frame 10a formed by bending the plate material into a U shape, and fixes the binding tape t so as to pass inside the frame 10a.

At this time, it is preferable that at least one of the electric heaters 11 is fixed to the lower surface of the inner surface of the frame 10a from the viewpoint of thermal efficiency, and that the heating wire is covered to prevent the binding tape t from burning. It is preferable to do so.

The binding tape t is generally formed of a vinyl chloride material or a polyethylene material, in which case the tape heater 10 can heat the binding tape t to any substantially constant temperature within the range of 30 ° C to 60 ° C. Make something.

Explaining an example of use of the binding machine according to the present invention described above, the electric heater 11 of the heater 10 is not energized during the summer, while it is energized when it is cold in the winter and the binding tape t is not shown. The controller is operated to heat to a constant temperature of 30 ° C. or higher.

As a result, the binding tape t is placed at the position of the noodle band group w grasped by the chuck 4 at about 20 ° C. to 3 ° C. throughout the year.
It will be maintained at about 0 ° C.

Therefore, if the binding tape t is made to exhibit an appropriate elasticity when the temperature is about 20 ° C. to 30 ° C., a reliable binding process can be performed throughout the year by using one type of the binding tape t. You will be told.

Especially when used in a cold region, the binding tape t needs to be kept at a relatively high temperature. In such a case, the binding tape t is placed at the position of the heater 10, for example, 6 mm.
It is heated to about 0 ° C., and the binding tape t heated in this way is cooled to the outside air before reaching the position of the noodle band group w, and is brought to an appropriate temperature at the moment of binding.

In practice, the optimum heating temperature of the binding tape t at the position of the heater 10 varies depending on the surrounding environment and the processing speed. Therefore, when setting the temperature of the heater 10, the binding process is performed at various tape temperatures. By repeating the trial a plurality of times, the set temperature is asymptotically determined so that the binding tape t exhibits optimal elasticity at the position of the noodle band group w.

During the binding process, the binding tape t is pulled out to the tape feeding device 9 by overcoming the pulling resistance of the roll winding tape of the tape supporting device 8 by the winding force of the noodle string group w rotated by the chuck 4. Further, it is pulled out to the position of the noodle band group w by overcoming the pulling resistance which is intentionally given by the feeding device 9 and adjusted to an arbitrary constant size.

Therefore, the tensile force acting on the binding tape t between the tape supporting device 8 and the tape feeding device 9 is smaller than the tensile force acting on it between the tape feeding device 9 and the noodle band group w position. This is the heater 10
This contributes to preventing the binding tape t, which is heated to the highest at the position of, from abnormally extending at the position of the heater 10.

Further, the binding tape t has different properties with respect to temperature depending on the material, and even if the same material is different depending on the dimensions such as the thickness thereof, in the present invention, the binding tape t can be arbitrarily heated in a wide temperature range, so that a wide range is obtained. Things can be used.

[0029]

According to the present invention configured as described above, the binding tape fed to the position of the noodle band group can be kept at an appropriate temperature regardless of the temperature, and therefore a small number of binding tapes are prepared. This makes it possible to always wrap the binding tape around the noodle band with an appropriate tensile force, regardless of changes in the four seasons or differences in use locations such as warm regions and cold regions.

Along with this, the work of exchanging the binding tape and the readjustment accompanying it is reduced.

According to the second aspect of the present invention, by using one kind of binding tape, it is possible to perform the binding processing with a proper fastening force over the whole year.

According to the third aspect of the present invention, since the U-shaped frame is formed, heat is easily accumulated inside the frame so that thermal efficiency in heating the tape is improved, and the tape is arranged in the tape path. At this time, the binding tape can be put inward from the opening portion of the frame, which facilitates the arrangement work.
