Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a V-guide bonding machine for a resin belt, and more particularly, to a V-guide bonding machine for continuously and thermally welding a V guide for meandering prevention to the back surface of a resin belt.

[0002]

2. Description of the Related Art In a resin conveyor belt for conveying relatively light articles such as those related to food and distribution, a V guide for preventing meandering is often provided on the back surface in order to align and detect the articles to be transferred. The V guide is usually attached continuously in the belt length direction to the center of the back side of the conveyor belt in the width direction, and as a V guide attaching device, a belt B is conventionally fixed in the length direction as shown in FIG. Pinch rolls A, A transported at a speed, a roll D for supplying a V guide material C to a central portion in the width direction of the belt B to be transported, and hot air reaching the melting temperature to the V guide material C and the central portion of the belt B A device provided with a heating jet nozzle E for spraying a belt is transported in a direction indicated by an arrow X, and at the same time, a V guide material C is supplied by a roll D to supply a heating jet nozzle E.
There is known a method in which both surfaces facing each other are melted by hot air blown from the surface, the melted portions are opposed to each other, and then uniformly pressed by a manual roll F or the like to perform heat welding.

[0003]

However, the above-mentioned apparatus has a problem that the width of the pinch rolls A, A with respect to the belt is constant and cannot be applied to a belt wider than the pinch rolls A, A. Since the subsequent V guide material C is pressed by the manual roll D, there is a problem in that the adhesive strength becomes uneven and the adhesive strength cannot be made uniform.

Further, when the belt is long, a roll for winding and storing these belts is required. In addition, since the entire apparatus is fixed to a large gantry, it is necessary to transport the conveyor belt to the apparatus. There was a disadvantage.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a V guide attaching machine for a resin belt which can attach a V guide very easily and has excellent uniform linearity. It was done as.

[0006]

That is, the resin belt V guide attaching machine of the present invention has a carriage which can be moved linearly at a constant speed, and a carriage which is supported by the carriage and which is fixed at a predetermined position on the base surface of the lower surface of the carriage. A heated jet nozzle for blowing hot air toward the nozzle and a resin belt V guide attached face facing the spraying surface of the heated jet nozzle are supplied reversely, and the resin belt V guide is pressed in the base direction. And a guide pulley.

[0007]

Next, an embodiment of the present invention will be described. FIG. 1 is a side sectional view of an embodiment of the present invention, FIG. 2 is a front view of the embodiment,
FIG. 3 is a side view showing a use state of the embodiment. The resin belt V guide attaching machine 1 of the present invention uses a motor M as a drive source, and blows out a hot wind toward a truck 2 which can be moved linearly at a constant speed and a fixed portion P on a base surface 3 on the lower surface of the truck 2. Heating nozzle 4 to be heated, and an adhering surface C1 of a resin belt V guide C facing the spraying surface P of the heating jet nozzle 4
Is supplied in reverse to face each other, and V guide C for resin belt is provided.
And a guide pulley 5 for pressing in the direction of the base surface 3.

In the above embodiment, the straight running of the carriage 2 is such that one of the wheels 2A of the carriage 2 is fitted to a straight guide rail 2B installed in parallel with the end of the belt as shown in FIG. Then, by moving along the guide rail 2B, it is made to move linearly. If a certain curvature is defined for the guide rail, the V guide according to the curvature can be adhered. Further, the guide pulley 5 may be configured to be freely rotated to supply the V guide as the carriage moves, or may be configured to be driven and rotated by the motor M at a speed synchronized with the movement speed of the carriage.

[0009]

In order to attach the V guide C to the resin belt B using the resin belt V guide attaching machine 1 of the present invention, first, the resin belt V guide attaching machine 1 is placed on the resin belt B laid flat. The guide rail 2B
The guide pulley 5 guides the V guide C to hold the end between the resin belt B on the lower surface and the guide pulley 5.

In this manner, heated air is ejected from the heated jet nozzle 4 and the adhesive surface of the V guide C and the resin belt B
Are heated to the melting temperature and the carriage 2 is gradually moved. With this movement, the V guide C is sent to the surface of the resin belt B by the guide pulley 5, and the hot melt surface is pressed by the guide pulley 5 and adhered. At this time, the pressing force of the guide pulley 5 is obtained by the weight of the bogie and the like, and is always constant. Therefore, the V guide C is uniformly and thermally welded to the resin belt B in a constant state.

[0011]

[Effect of the Invention] As described above, the present invention is constructed such that a heating jet nozzle and a guide pulley are mounted on a carriage and the carriage is welded while moving along the resin belt. Adhesive work can be performed at any place as long as there is a place where it can be deployed and placed, and there are no restrictions on the location, and since the V guide that is heated and welded as it moves is pressed by the guide pulley with a constant pressing force, the adhesive force is also constant It has various practical effects, for example,
