DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for binding long objects such as aluminum sashes.

[0002]

2. Description of the Related Art As a conventional method of binding long objects, for example, as shown in Japanese Utility Model Publication No. 3-22148, two types of long aluminum sashes having different length dimensions are firstarily provided for each type. As a binding body, the surroundings of the aluminum sash material are wound in a state of being overlapped in a state where a tensile force is applied by a plastic stretch film to perform a binding treatment, and then each primary binding body is accumulated, and the lengthwise direction is collected. There has been known a bundling method in which an intermediate portion is appropriately bundled at a time and a space is formed between the overlapping portions so that no scratch is generated on the opposing surfaces thereof.

[0003]

However, in the conventional tying method, the primary tying is integrated and tied together, so that it takes two steps and is troublesome, and a plastic stretch for tying. There are many problems such as consumption of a large amount of film. Therefore, the present invention solves the conventional problems, and in a single step, consumes a small amount of a bundling film, thereby bundling a long object without causing a shift and generating a scratch on an opposing surface. And a binding device therefor.

[0004]

According to the present invention, in order to achieve the above object, two long objects A and B, which are objects to be tied, are arranged at an interval, and a tying object is provided within the interval between the two objects. After the start end of the narrow film F is inserted, the two long objects A and B are closed and joined together, and then the rear end side of the sandwiched narrow film F for binding is joined. The two long objects A and B are wound around at least once and cut, and the cut ends are fixed to the wound narrow film F for bundling to obtain two long objects. A and B are united. A narrow film F for binding is provided on the side surface of the standing binding substrate 1.
The winding drum 2 provided with the mounting shaft 6 of the film roll 5 on which the film is wound is rotatably mounted. Inside the winding drum 2, a narrow film F for binding which moves upward, backward, downward, and forward is moved. , And a cutter 10 for cutting the rear end of the thin film F, which has been bound, and a long object which is two objects to be bound at the binding position of the winding drum 2. The apparatus comprises a clamper 11 for joining A and B to form a long-length binding apparatus.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a tying device for carrying out the method of tying a long object according to the present invention. As shown in FIG.
The ends of the long objects are bound by a narrow film for binding. The bundling device is installed symmetrically to bind both ends of the two long objects A and B. However, since the left and right bundling devices have the same structure, only one will be described and the other will be omitted. The binding device includes a winding drum 2, a gripper 8, a cutter 10, and a clamper 11. The winding drum 2 is erected so as to bind an end of a long object to be bound. Is attached to the side surface of the bound substrate 1, and is supported and guided by three guide rolls 3 inscribed in the winding drum 2, and is rotated by a belt 4 wrapped around the peripheral surface of the winding drum 2. It is configured.
As shown in FIG. 1, a narrow film for binding (hereinafter simply referred to as a film) F is provided on the side surface of the winding drum 2 as shown in FIG.
And a guide roll 7 for guiding a film F drawn out slightly apart from the mounting shaft 6, respectively. The gripper 8 is disposed in an opening 9 provided in the binding substrate 1 in the winding drum 2 and is configured to move upward, backward, downward, and forward as shown by arrows in FIG. The film F is inserted between the two long objects A and B while holding the start end of the film F therebetween. The cutter 10 is arranged at the end of the opening 9 of the binding substrate 1 in the winding drum 2 in the same manner as the gripper 8 as shown in FIG. Is configured to be cut. Winding drum 2
A clamper 11 is disposed in front of the winding drum 2. The two long objects A and B, which are the objects to be tied, which are transported by the two clampers disposed above, not shown, are disposed at the center of the winding drum 2. It is placed at an interval on a guide bar 12 provided at the front binding position, and the long object A,
After the film F is inserted between B, the film F is brought into close contact with each other and operates so as to sandwich the film F. Note that the left and right bundling devices are configured so that their intervals can be adjusted according to the length of the long object to be bound.

Next, the method of binding long objects will be described. FIGS. 3 to 6 show the binding method in order.
This is an example of the binding of different types of long objects having different widths as the objects to be bound. And the binding material uses a narrow film, but especially the films are easy to adhere,
When using a plastic stretch film such as polyethylene or polybutadiene, which has the property of expanding and contracting in the length direction, the films are directly contacted without using adhesive or heat when fastening the cut ends of the unity. Can be easily fastened. First, the gripper 8 holding the starting end of the film F is interposed between the long objects A and B transported and arranged at an interval at the binding position in front of the center of the winding drum 2 as shown in FIG. The film F is moved to the upper position T and the film F is arranged between the long objects A and B. Then, as shown in FIG. 4, the long objects A and B are brought into close contact with each other to hold the film F therebetween. Next, the winding drum 2 is rotated clockwise, and the film F is wound around the long objects A and B by one rotation as shown in FIG. At this time, the gripper 8 holding the film F at the upper position T releases the film F and retreats to the chain line position shown in FIG. 2 so as not to hinder the winding of the film F. Next, the gripper 8 moves to the lower position, and when the winding drum 2 makes one rotation and the film F returns to the original position shown in FIG. 3, the gripper 8 moves forward and the rear end of the film F as shown in FIG. Hold the part. Then, the cutter 10 moves forward and cuts and retreats above the gripper 8. FIG. 6 shows a cross section of a long bundle of the long objects after the binding, and the film F includes two long objects A and B.
The film F is wound and bound around it while being sandwiched therebetween, and the cut end of the bundle is fixed to the wound film F by any fastening means such as an adhesive, heat, or pressure welding.
FIG. 7 is a perspective view of a long object that has been bound and shows a state in which both ends are bound by a film F. Even if the long objects A and B having different widths are bound. By binding the film F between the long objects A and B, the occurrence of displacement during transportation is prevented, and a small space is formed on the facing surface other than the binding part of the long objects A and B. This is a bundling method that has an advantage that contact scratches do not occur because of the formation of the contact holes. In addition, it is also possible to use a stretch film as a binding material, apply a tensile force, bind the film, and generate wrinkles on the film surface, thereby forming a space in the binding portion to prevent the occurrence of contact scratches. .

[0007]

The present invention has the above-mentioned structure, and has a binding film sandwiched between two long objects to be bound, and is wound around the periphery at least once to bind the film. As a result, the bundling process can be completed in one step, automation is easy, the amount of bundling film used is small, and the bundling film sandwiched between two long objects is being transported. It has many excellent effects of preventing displacement and preventing scratches on the opposing surface. In addition, the bundling device enables the bundling to be automated with a simple mechanism.The bundling drum on which the film roll of the bundling film is attached is rotated around the material to be bound to bind it efficiently. It has excellent effects such as the ability to work.
