BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding cord cutting device,
In particular, it relates to a device for cutting a binding string of a binding assembly.

[0002]

2. Description of the Related Art Generally, a pallet container holding a predetermined number of beer bottles and the like is stacked in several rows and is transported by bundling the upper part of a stack assembly. It was cut and the string was pulled up and collected. Therefore, it was necessary to always have a specialized worker for stringing.

Therefore, there has been proposed an automatic string take-out and unwinding machine which is capable of automatically cutting and collecting the string that binds the pallet loading containers and the like. FIG. 6 is a front view of a cutting device used in a conventional automatic stringing and unwinding machine. Reference numeral 1 in the figure
Reference numeral 01 denotes a plate, and the plate 101 is formed with a guide slit 101a and a guide portion 101b for guiding a cord to the guide slit 101a. A cutter 102 is held on the plate 101 so as to be movable in the vertical direction in the figure, and a spring 103 is interposed between the cutter 102 and the plate 101. The spring 103 constantly urges the cutter 102 upward in the drawing.

FIG. 7 is a schematic view for explaining the operation of the above cutting device. The cutting device 104 is attached to the drive chain 105, and by this drive chain 105, the cutting device 1
04 moves in the direction of the arrow in the figure. In addition, a plurality of cases 10 are provided on the side of the drive chain 105 (on the right side of the drawing).
, 106, ... Are stacked, and a binding assembly 108 bound by a binding string 107 is arranged. In such a situation, when the drive chain 105 operates and the cutting device 104 moves in the direction of the arrow in the figure, the binding cord 107 is hooked on a string hooking rod (not shown) or the like and pulled toward the cutting device side, and the guide portion 101b. Guided by the guide slit 1
01a and abuts on the cutter 102. Then, the binding cord 107 is moved by the cutting device 104 so that the cutter 102
Works to push the spring 103 downwards in the figure against the urging force of the spring 103. However, when the urging force of the spring 103 exceeds a certain level, the cutter 1 is urged by the urging force of the spring 103.
02 moves upward in the figure. At this time, the binding cord 107 is cut.

[0005]

However, in the cutting device having the above-mentioned structure, when the cord is cut, the positions of the blades to be abutted are almost always the same, so that the life of the blades is short. is there. Also, when the string is multi-winding, if the tension of each winding of the multi-winding string is different, it can only be cut with a sharp blade, so the blade must always be managed to be sharp to some extent. However, there is a problem that the number of times of polishing increases.

The present invention has been made in view of the above problems, and extends the life of the blade and, even in the case of multiple winding, a binding cord that does not need to be managed by increasing the number of times of polishing. An object is to provide a cutting device.

[0007]

SUMMARY OF THE INVENTION The present invention comprises a substrate, a clamp member provided on the substrate for clamping the binding cord, and a cutter for cutting the binding cord, and the assembly bound by the binding cord. In the binding string cutting device arranged on the side of the body, movably provided on the substrate,
The cutter includes a holding member that holds the cutter, and an elastic member that is interposed between the holding member and the substrate and that urges the holding member in one direction. The cutter includes two rotary blades. The tie string is cut between the two rotary blades.

[0008]

When the board moves, the binding string comes into contact with the cutter. Further, when the substrate moves, the holding member holding the cutter moves against the substrate against the biasing force of the elastic member. Then, when the biasing force of the elastic member reaches a certain magnitude, the holding member moves with respect to the substrate by this biasing force. By this movement, the binding string is cut by the cutter composed of the two rotary blades.
