FIG. 1 is a front view of a bow and arrow recovery device provided in the lower part of the floor of the archery where the Karakuri doll bow-drawn children are placed, and FIG. 2 is a front view of the bucket part installed below the floor below the target. 3 is a right side view of FIG. 2, FIG. 4 is a right side view showing a first chain conveyor installed below the bucket, FIG. 5 is a plan view of FIG. 4, and FIG. FIG. 7 is a left side view showing a third chain conveyor, and FIG. 7 is a front view showing an arrow pushing mechanism at the front end of the third chain conveyor.

  In FIG. 1, when Karakuri doll bow pulling child D placed in the archery takes arrow A from Yadate S, pulls bow B, draws bow B, and shoots arrow A, arrow A hits target T Then, it falls on the floor G. As shown in FIGS. 2 and 3, the bucket 2 is installed on the floor G below the target T via the spring 1, and the arrow A falls into the bucket 2. At this time, the vibrator 3 attached to the outer surface of the bucket 2 is operated. As a result, the arrow A falls to the bottom 2 a without being caught by the inner wall of the bucket 2. The bottom 2a of the bucket 2 is formed in a size that is parallel to the injection direction of the arrow A and accommodates the arrow A, and is further closed by a horizontal shutter 4. A magnetic sensor 5 is attached to the front and back of the bottom portion 2a to detect the fall of the arrow A. Note that a photoelectric sensor may be used instead of the magnetic sensor 5.

  When the magnetic sensor 5 detects the fall of the arrow A, the solenoid 6 shown in FIG. 3 is actuated to move the shutter 4 to the right and open, and the arrow A is an arrow pedestal on the chain conveyor 7. Drop on 8 The arrow receiving base 8 has a V-shaped main body 8c at the upper end of L metal fittings 8b erected on the left and right sides of a horizontal plate 8a supported so as to be rotatable about a vertical axis on a support base 7a on a chain conveyor 7. It is supported so that it can rotate around its axis. A weight 8d is suspended below the main body 8c, and the main body 8c is always supported so as to keep the upper position. Although not shown, a magnet is disposed between the support base 7a and the horizontal plate 8a so as to hold the position each time the horizontal plate 8a is rotated 180 degrees.

  The arrow A that has fallen on the arrow cradle 8 is held on the main body 8c. In this state, the magnetic sensors 9 arranged on the left and right of the arrow A detect the metal of the heel portion of the arrow A, and determine the front-rear direction of the arrow A. In FIG. 2, the emission direction of the arrow A, that is, the direction in which the right side of the drawing is a ridge is defined as a positive direction. Here, when the arrow A is in the opposite direction (the heel is on the left side), the pinion 12 driven by the motor 11 (FIG. 4) disposed in the chain conveyor 7 is moved forward, and the pinion at the lower end of the support shaft of the horizontal plate 8a. After connecting to 8e, rotate 180 degrees to correct in the positive direction.

  When the arrow A falling on the arrow pedestal 8 is in the forward direction, and since it is in the opposite direction, the main body 8c is reversed, and then the chain conveyor 7 is placed at a right angle to the exit direction of the arrow A as shown in FIGS. Advance in the direction. A chain conveyor 13 is disposed in front of the chain conveyor 7 in the direction opposite to the direction of emission of the arrow A. On the chain conveyor 13, arrow receiving bases 14 and 15 are arranged at intervals slightly shorter than the length of the arrow A, and when the chain conveyor 7 moves forward, the chain conveyor 7 stands by at the reverse position of the front end of the chain conveyor 7. As the chain conveyor 7 advances, the arrow A carried by the arrow pedestal 8 is transferred to the arrow pedestals 14 and 15 while being inverted at the front end.

The chain conveyor 17 is provided with an arrow pedestal 18 that receives the arrow A from the arrow pedestals 14 and 15 of the chain conveyor 13. When the chain conveyor 13 moves forward, it is below the arrow transfer position near the front end of the chain conveyor 13. Waiting. When the chain conveyor 17 is not in operation, the chain conveyor 17 rotates about the sprocket shaft at the rear end and descends to the horizontal direction, and the front end of the chain conveyor 17 is hidden below the floor G to operate the bow-drawn child D. I do not impair the appearance of.

  When the chain conveyor 13 starts moving forward, the chain conveyor 17 is also rotated, and the front end rises to the pushing position behind the arrow stand S. When the chain conveyor 13 moves forward and the arrow receiving bases 14 and 15 stop at the arrow transfer position, the chain conveyor 17 is activated, and the arrow receiving base 18 receives the arrow A from the arrow receiving bases 14 and 15 and obliquely upwards. Advance. When the arrow cradle 18 moves forward and reaches the pushing position behind the arrow stand S, the chain conveyor 17 stops. As shown in FIG. 7, an extrusion mechanism 20 supported on the chain conveyor 17 side is provided at this pushing position.

  The push-out mechanism 20 includes a motor 21 with a speed reducer, a pinion (not shown) rotated by the motor, a rack 22 and a push-out bar 23. When the chain conveyor 17 is operated, the rack 22 and the push-out bar are arranged. When the chain conveyor 17 is operated and the arrow receiving base 18 on which the arrow A is placed is stopped at the pushing position, the motor 21 with a speed reducer is activated to advance the rack 22, and the tip of the push bar 23 is moved forward. Is pushed against the rear end of the arrow A to advance. The forward stop position and the backward stop position of the rack 22 are detected by the micro switches 24 and 25 provided before and after the rack 22.
