Strip continuous product is or those with winding means such as the core and the winding drum, so that belting for safety belts formed of thick fabric, continuous product itself does not include the winding means Some are provided in a wound state. In any case, the conventional feeding device sequentially feeds the wound material while being supported by the support shaft. Therefore, when replacing the wound material, it is necessary to always attach the wound material to the support shaft, and it is very labor-intensive in the process that is performed manually, and the cost increases when using special equipment. There were drawbacks.

  Further, when a continuous material is fed out from a wound material mounted on a support shaft, it often causes slack, so that it is usually necessary to arrange a tension roller, and there is a drawback that the structure of the apparatus is complicated.

  In view of the above disadvantages of the prior art, the present invention eliminates the need for attaching the wound material to the support shaft when replacing the wound material, and improves work efficiency and simplifies the overall device structure. An object of the present invention is to provide a device for feeding a continuous product in a wound state.

In order to achieve the above object, the invention described in claim 1 uses a horizontal mounting table 3 provided with a peripheral wall 4 so that the hooked winding drum 7 around which the continuous material 1 is wound does not slide down. A part of the peripheral wall 4 of the mounting table 3 is provided with a notch portion 5 having a width that allows the continuous object 1 to be pulled out, and a guide pin 6 that guides the continuous object 1 is erected in the notch part 5.
The winding drum 7 with the hook around which the continuous material 1 is wound is placed so that the side surface thereof comes into contact with the surface of the mounting table 3, and one end of the continuous material 1 is connected to the mounting table 3 via the guide pin 6. The continuous drum 1 wound around the take-up drum 7 is fed out by pulling out to the outside and rotating the take-up drum 7 on the mounting table 3 by a pulling force from the outside.

The mounting table 3 is formed of a material that generates an appropriate frictional resistance with the side surface of the winding drum 7 . That is, the winding drum 7 is idled by the pulling force of the continuous material 1 and is formed of a material that generates a resistance force that prevents the winding drum 7 from excessively rotating due to inertia.

According to the first aspect of the present invention, it is not necessary to mount the take-up drum 7 on the support shaft when the continuum 1 is attached or replaced, and the work efficiency can be improved. In particular, in the method of the traditional you attach and detach the winding drum 7 by hand, but was sometimes forced to hard labor, it is possible to perform the work more easily According to the first aspect of the present invention. In addition, there is an effect that the apparatus can be simplified and the manufacturing cost can be reduced.

Since the mounting table 3 is made of a material that generates an appropriate frictional resistance with the side surface of the winding drum 7, the winding drum 7 is idled by the pulling force of the continuum 1, and the winding drum 7 is driven by inertia. Produces resistance that does not over-rotate.
When the continuous object 1 is pulled, the take-up drum 7 rotates on the mounting table 3 while rotating and the continuous object 1 is fed out. At this time, due to the presence of the peripheral wall 4, the winding drum 7 does not fall and reluctantly moves within the region surrounded by the peripheral wall 4.

Hereinafter, the dispensing apparatus consecutive of wound state according to the present invention, the embodiments implemented as dispensing apparatus of the band-like material such as belts material of the safety belt will be described with reference to the accompanying drawings.

FIG. 1 is a front view of the whole continuous material feeding device in a wound state, FIG. 2 is a plan view, and FIG. 3 is a front view of a cutting device that intermittently draws out the belt material as a continuous material and cuts the belt material. FIG. 4 is a perspective view of the mounting table.
Feeding of the continuous of wound state illustrated embodiment apparatus, in knitted or woven fabric of strong fibers, for example, a strip der Ru continuous product having a width of about 5cm winding drum winding turn was state or al sequentially It is an apparatus for drawing out, cutting to a desired dimension, and supplying it to the next step.

As shown in FIGS. 1 and 2, the winding drum 7 wound with a continuous material is placed on the mounting table 3 that is formed as a horizontal surface without being pivotally supported, and the side surface of the winding drum 7 is applied to the surface of the mounting table 3. It is placed in contact. Stage 3 of the illustrated embodiment, the plane of the substantially square, so that the winding drum 7 on the outer peripheral sliding off, is provided with a high peripheral wall 4 than the width of the winding drum 7.

A part of the peripheral wall 4 is provided with a notch part 5 for drawing out the continuous object 1 and two guide pins 6 and 6 are erected so that the continuous object 1 does not directly contact the notch part 5 of the peripheral wall 4. doing. The mounting table 3 is made of a smooth synthetic resin, and the peripheral wall 4 is made of, for example, stainless steel.
In this case, the material of the table 3, in relation to the material and the weight of the winding drum 7, a winding material 2 when forcibly pull the one end of the continuous material 1 winding drum 7 is table 3 above The material 1 is selected by pulling (continuously) the continuous material 1 at the time of (1) and pulling out the continuous material 1 and having a frictional resistance that prevents the wound material 2 from over-rotating due to inertia.

When the continuous object 1 is pulled , the take-up drum 7 that is a wound object is rotated on the mounting table 3 while rotating and the continuous object 1 is fed out. At this time, due to the presence of the peripheral wall 4, the winding drum 7 does not fall and reluctantly moves within the region surrounded by the peripheral wall 4. The guide pin disposed in the cutout portion 5 of the peripheral wall 4 is disposed at a position where the continuous object 1 is largely folded back (substantially 170 degrees in the drawing), and the guide pin 6 has a cylindrical shape that does not idle. Thereby, it functions as a resistor for the continuous object 1 that is fed out, and even if the continuous object is rewound a little on the mounting table 3, it is possible to prevent the continuous object from being immediately fed out of the mounting table. Due to the frictional resistance of the mounting table and the frictional resistance of the guide pin, it is not necessary to provide a means for preventing slack such as a tension roller between the mounting table 3 and the drive portion for pulling out the continuous object 1.

  In the case where the continuous object 1 is a belt-like object, the surface of the belt-like object fed out from the mounting table 3 is in the vertical direction. The drawn continuous belt-like continuous object is turned to a horizontal state via the guide rollers 9 and 10, and is sent out to the driving device 11 for forcibly feeding the continuous object.

  The driving device 11 includes two sets of nip roller units 12 and 13 and a cutting unit 14. That is, the continuum 1 is forcibly pulled out by the two sets of nip roller units 12 and 13 by a necessary amount, the upstream nip roller unit 12 is stopped, and then the downstream nip roller unit 13 is operated to pin the continuum. The continuum 1 is cut by the cutting unit 14 while maintaining the tension. That is, the continuous object 1 is sent out intermittently.

  When the continuous object 1 is continuously fed out at a constant speed, there is little possibility of over-rotation of the wound object, but when there is a speed change in the feeding-out, there is a possibility of over-rotation. For this reason, it is preferable that the feeding (feeding) speed of the nip roller units 12 and 13 is driven with the speed change as small as possible. The inertial force acting on the wound object 2 on the mounting table 3 changes depending on the speed change and the overall feeding speed.

The excessive rotation of the wound material 2, that is, the winding drum 7 generated by the inertial force, varies depending on the frictional resistance between the winding drum 7 and the mounting table 3, the feeding speed of the continuous object 1, and the speed change of the feeding speed. Therefore, practicing the present invention, the material selection and surface treatment of the table 3 in consideration of the frictional resistance between the side surface of the winding drum 7, by the speed setting delivery by nip roller unit is the winding material 2 It is possible to realize a stable operation state in which the winding drum 7 does not cause excessive rotation as much as possible.

1 to 4, continuous product 1 is a belt-like material, shows a device for feeding the wound material 2 or we required length of the state of winding a continuous material 1 itself. That is, the side surface of the take-up drum 7 that is the wound product 2 around which the continuous product 1 is wound comes into contact with the mounting table 3, and excessive rotation is prevented by the frictional resistance .

Continuous product 1, because it was wound up drum 7 wound, so that the side surface of the winding drum 7 abuts the surface of the table 3. Therefore, the material of the side surface of the winding drum 7 and the material of the mounting table 3 are selected as a combination of materials that generate an appropriate frictional resistance. The mounting table 3 preferably uses a synthetic resin material in order to realize a smooth and constant state. On the other hand, the side surface of the winding drum 7 is preferably made of a material that does not damage the mounting table 3.

  The winding drum 7 is generally made of metal or wood from the viewpoint of strength. In this case, in view of generation of frictional resistance with the mounting table 3 and protection of the mounting table 3, a relatively soft material such as cloth is attached to the side surface of the winding drum 7, and a fiber is coated to implement the present invention. Can be made without any problems.

Continuous product 1, because it was wound up drum 7 wound, not only strip as a continuous material 1, wire, such as a rope, can be implemented as a delivery device for the cord-like material. In the present invention, since a winding drum is used as the wound material, the material is always placed between the winding table 7 and the mounting table 3 by selecting the material of the winding drum 7 or the side surface of the winding drum regardless of the material of the continuous material 1. An optimum frictional force can be generated, and a stable delivery state can be realized.
