  An example of the present invention will be described.

  First, the drawings will be explained. FIG. 1 is an overall side view, FIG. 2 is an overall plan view, FIG. 3 is an overall front view, FIG. 4 is an overall rear view, and FIG. FIG. 6 is a perspective view showing the relationship between the vibrating rod and the bush shown in FIG. 5, and FIG. 7 is an enlarged front view of a rubber band (O-ring).

  In the figure, reference numeral 1 denotes a vibrator provided on a mounting base H such as a frame, a base, or a processing machine. The vibrator 1 is provided with a vibrating rod 2 for supporting a rubber band A in a substantially horizontal state. . In addition, the tip 200 of the vibrating rod 2 has one vertical end surface 2 a that constitutes the groove 4. The tip 200 is detachably provided with a bush 5 having the other end face 5a (inclined end face) constituting the groove 4 and a groove bottom 5b. The bush 5 is made of resin, and can be replaced in accordance with damage and the ring dimension and form of the rubber band A. The vertical end surface 2a of the tip 200, the other end surface 5a of the bush 5 and the groove bottom 5b have a structure substantially corresponding to the annular dimension (width and height) of the rubber band A. Further, the rubber band A is separated by making one vertical end surface 2a of the vibrating rod 2 into a vertical shape. In the drawing, reference numeral 400 denotes a semi-groove groove constituted by the other end face 5a and the groove bottom 5b. Further, by making the other end surface 5a an inclined end surface, for example, ironing of bundled or stacked rubber bands A is ensured, and one rubber band A is reliably left in the groove 4, that is, reliable and smooth. Allows separation. In the figure, 6 indicates a stopper.

  In the figure, reference numeral 7 denotes a support base, and the support base 7 is provided with a cylinder 8 (moving means). The movable rod 10 provided on the rod 800 of the cylinder 8 is provided with a separation link 11 so as to be movable. A horizontal portion 1102 and a wedge portion 1100 are formed on the upper end 11a of the separation link 11, and this wedge is formed. The separation link 11 is configured to move in one direction “arrow a” from the tip 200 of the vibrating rod 2 toward the rear 201 via the portion 1100, and in the other direction “arrow b” (the reverse of one direction). Has a non-movable (fixed) structure. By moving in one direction, the rubber band A can be inserted and / or mounted on the vibrating rod 2 and fixed in the other direction, so that one rubber band A can be surely dropped in the groove 4. That is, the separation link 11 and the fixed rubber rubber A among the plurality of rubber bands A at the tip portion of the vibration rod 2 are dropped into the groove 4, and the dropped rubber band A is formed into the groove 4. The one rubber band A is separated while being locked by one vertical end surface 2a so as not to be separated from the one.

  A universal means 12 is provided between the rod 800 and the movable rod 10 to guarantee the movement of the rod 800 and to make sliding contact with the upper surface 2b of the vibrating rod 2 of the separation link 11 (movement in the longitudinal direction). ).

In the figure, reference numeral 1101 denotes a buffer member provided on the movable end surface of the separation link 11, which is intended to be replaced when the buffer member 1101 is worn out and to be surely separated. In this example, resin is used to avoid reliable separation and damage to the rubber band A.

  In the figure, reference numeral 14 denotes a guide means having one end supported by the movable rod 10, and this guide means 14 is intended to prevent the movable rod 10 from moving forward and backward and to prevent blurring, and to the upper surface 2b of the vibration rod 2 of the separation link 11. The structure ensures sliding contact, and ensures the reliable movement of the separation link 11 and / or the rod 800, and also plays a role of eliminating damage to the rod 800, the separation link 11, and the like. The guide means 14 includes a rod 1400 and a base 1403 provided on the support base 7 having a through hole 1401 for guiding the rod 1400. In addition, a structure in which unevenness is formed on a part or the whole of the upper surface 2b to be aligned and separated in advance is also possible.

  The structure of the rubber band feeding device is constructed in the order of the vibration rod 2, the rod 800 of the cylinder 8 and the rod 1400 of the guide means 14 from the lower side, but the movement of the separation link 11 and the effective use of the space In view of the above, this is a preferred example and is not limited. For example, the guide means 14 can be provided along with the vibration cage 2.

  Accordingly, the operation of the rubber band feeding device of the present invention will be described. While pressing the separating link 11 in the direction of the arrow “A”, a large number of rubber bands A are mounted on the vibrating rod 2 (one surface A1 of the rubber band A is attached). And the other surface A2 is in a free state). At this time, the rubber band A can be inserted into the vibrating rod 2 and suspended without any resistance by moving the separation link 11 in the direction of “arrow A”. By separating the rubber band A from the separation link 11 after the mounting, the separation link 11 is automatically returned in the direction of “arrow B”, and the rubber band A is not detached from the vibrating rod 2. As described above, the rubber band A is supported on the one side A1 (upper), and there is little clumping, and in the unlikely event that the banding is schematically shown in FIG. is there.

  Then, in this state, the vibrator 1 is driven (may be driven in advance), and vibration is applied to the vibration rod 2 so as to impart a slight vibration to the mounted rubber band A. Are aligned and separated, and the vibrating rod 2 is moved to the tip 200. Through this movement, when several rubber bands A reach the groove 4, the rod 800 and / or the rod 1400 located on the tip 200 side moves backward (movement in the direction of “arrow A”, hereinafter The same), and the separation link 11 is retracted by utilizing the retreat.

  Since the separation link 11 and / or the buffer member 1101 move so as to slidably contact the upper surface 2b of the vibrating rod 2 at the time of the above-described retreat, one rubber band A is left in the groove 4 and the other rubber bands A are moved backward. Transport in the direction. The rubber band A is left in the groove 4 one by one through the movement of the separation link 11 and its sliding contact. Therefore, the rubber band A remaining in the groove 4 is in a free state and can be easily grasped and transported by hand or a transport robot. In addition, it is possible to catch each process with a sensor and control reliable feeding and machine movement.

  Thereafter, the rubber bands A can be fed out one by one sequentially by repeating the above-described operation. In the present invention, in the case of an O-ring, it is set on a factory automation line, and it is surely and automatically delivered one by one, can be adapted to the flow work, and can be supplied one by one reliably. In addition, when a container containing goods such as merchandise and food is fastened with a rubber band, this operation can be performed reliably and easily. It can also be used to tighten containers.
