Description

  The present invention relates to a ball picking machine for picking up tennis, golf and other balls into a collecting container.

Conventionally, a ball pickup machine using the rotation of blades has a required number of four blades formed of an elastic material such as rubber around the rotation shaft at a smaller interval than the diameter of the ball. The ball is bounced into the collection container with elasticity. (For example, see Patent Document 1)
Published practical use Showa 51-75360 specification (1st page-2nd page, Fig. 1)

  However, since the blade of this ball picking machine does not employ a structure in which the blade is sufficiently elastically deformed and then separated from the restraining member by stopping its tip against the restraining member. It is clear from experiments conducted by the present inventors that the ball that pushes up the introduction plate in the case of falling off the blade rolls back to the original position and is not collected into the collection container. Was not reached.

  In view of the present situation, the present invention forcibly causes the elastic deformation of the jumping blade that rotates by pushing the ball by the restraining member, and applies the repulsive force of this elastic deformation to the ball to jump into the collection container. It is an object of the present invention to make it possible to provide a ball pickup machine that can collect a ball into a collection container by rotating a jumping blade.

The present invention adopts the following configuration in order to solve the above problems.
In the ball picker that advances toward the ball that collects the collector body while rotating the jumping blade, jumps to the collection container attached to the picker body by the rotation of the jump blade, and collects it,
The jumping blade is formed of an elastic material having elasticity that can project a ball by a repulsive force when elastically deformed, and the jumping blade is formed below the ball introduction portion of the pickup body in correspondence with the jumping blade. A restraining member that hits the tip of the blade is provided, and the jumping blade that rotates by pushing the ball with the restraining member is elastically deformed backward in the rotational direction until the tip is released from the restraining member, and the repulsive force is applied to the blade. , The ball was jumped into the collection container.

  The bending part which makes an elastic deformation easy is formed near the attachment part to the rotating shaft of the said jumping blade.

In the ball picker that advances the pickup body toward the ball to be collected while rotating the jumping blade, jumps to the collection container attached to the picker body by the rotation of the jumping blade, and collects it.
The above-mentioned jumping blade is attached to the rotating shaft by a spring hinge, and when the jumping blade rotates around the hinge, the spring of the hinge is deformed so that the ball can be projected to the required distance by its repulsive force. Corresponding to the jumping blade, a restraining member that hits the tip of the jumping blade is provided below the ball introduction part of the main body of the pickup, and the tip of the jumping blade that rotates by pushing the ball with the restraining member from the restraining member The hinge spring is elastically deformed by rotating it backward in the rotational direction until it comes off, and the repulsive force is applied to the jumping blade to cause the ball to jump into the collection container.

  The effect of claim 1 When the collector body is advanced to the surface on which the ball to be collected is moved, the restraining member forcibly causes the elastic deformation of the jumping blade and applies the repulsive force to the ball. It is possible to automatically and efficiently perform the operation of picking up.

  Effect of Claim 2 Since the bending part provided in the attachment side of the jumping blade makes deformation of the jumping blade easier and easier, the failure of the jumping blade can be reduced.

  The effect of claim 3 When the jumping blade is attached to the rotating shaft with the spring hinge, the spring of the spring hinge is deformed by the rotation of the jumping blade to generate a repulsive force to jump the ball. Failures that break can be reduced.

  Embodiments of a ball collecting machine according to the present invention will be described below with reference to the drawings.

  In FIG. 1 and FIG. 2 showing this embodiment, reference numeral 1 denotes a ball pickup device according to the present invention. This ball pickup machine 1 advances the pickup body 2 toward the balls 4 to be collected while rotating the jumping blades 3, and the recovery container in which the balls 4 are attached to the pickup body 2 by the rotation of the jumping blades 3. 5 and is characterized in that the jumping blade 3 is formed of an elastic material and the ball introduction portion 6 is provided with a restraining member 7 for forcibly causing elastic deformation of the jumping blade 3. .

  The pick-up machine main body 2 is formed in a hollow frame-like body having a square cross section, and a net, bag, or other appropriate collection container 5 is detachably attached to the opening 8 at the rear end. The rubber band 9 or other appropriate stopping means is used to fix the ball 4 to the collecting body 2 so as not to be separated. And the introduction part 6 of the ball | bowl 4 is opened under the front part of the pick-up machine main body 2, and the part which faces the introduction part 6 is slightly between the introduction part 6 and the opening part 8 of a rear end. An inclined bottom portion 10 is provided which is flat and gradually increases behind it, and a guide piece 11 is provided above the bottom portion 10 for guiding the ball 4 jumped by the jumping blade 3 to the opening 8 of the collection container 5. It is provided.

  The introduction member 6 of the ball 4 in the pickup main body 2 is provided with the stop member 7 for forcibly causing the elastic deformation of the jumping blade 3 as described above. The restraining member 7 is formed at the tip of the flat portion 10 ′ of the bottom portion 10 of the pickup main body 2, and the height of the flat portion 10 ′ of the bottom portion 10 is pushed by the jumping blade 3 to move. The ball 4 can ride up without being caught, and the tip of the jumping blade 3 engages with the restraining member 7 and is elastically deformed to generate a repulsive force sufficient for the jumping blade 3 to jump the ball 4. Then, it is set so as to be disengaged from the restraining member 7, and the restraining member 7 has an inclined structure in which the rear side is higher than the front side.

  In order to provide the jump blade 3 inside the finder main body 2, a rotary shaft 12 is horizontally mounted on the front side of the finder main body 2, and a portion of the rotary shaft 12 positioned in the finder main body 2 is arranged. As shown in FIGS. 3 (a) and 3 (b), a square cross section is assumed. And, to the two opposing faces of this square cross section, a required number of jumping blades 3 formed in a strip shape with an elastic plate such as steel, synthetic resin, rubber, etc. are attached at intervals at which the balls 4 do not pass through, For attachment, one end of the jump blade 3 is attached to the rectangular cross section of the rotary shaft 3, the suppressor 13 is overlaid thereon, a screw 14 is passed through the suppressor 13 and the jump blade 3, and the screw 14 is rotated to the rotary shaft. By tightening to 12.

  As described above, the length of the jumping blade 3 attached to the rotary shaft 12 is preferably such that the tip is slightly separated from the surface 15 with the ball 4 so that the surface 15 is not rubbed during rotation. In the above-described embodiment, the two-set type projects from the rotary shaft 12 in two directions, but the four-set type projects from the rotary shaft 12 in four directions.

  The part of the rotary shaft 12 attached with the diving blade 3 that goes out of the main body 2 is a circular shaft 12a as shown by the dotted lines in FIGS. 3 (a) (b) and 4 (a) (b), This circular shaft 12a is fitted to a bearing 16 provided as shown in FIG. 1 on both sides of the picker body 2, and a wheel 17 is attached to the outer part of the bearing 16 so that the picker body 2 1 and 2, when the pusher 18 is pushed forward and the pickup body 2 is advanced, the wheel 17 rolls on the surface 15 with the ball to rotate the rotating shaft 12, and thus the rotation. The jumping blade 3 attached to the shaft 14 is also rotated so that the ball 4 jumps into the collection container 5.

  In the ball pickup machine 1 having the above configuration, when the target to be picked up is a tennis ball 4, the height of the stop member 7 provided at the entrance 6 of the pickup machine body 2 is about 3 mm higher than the surface 15 on which the ball 4 is located. When the pickup body 2 is advanced toward the ball 4, the wheel 17 rolls to rotate the jump blade 3 on the rotary shaft 12. For this reason, when the tip of the jumping blade 3 hits the ball 4 as shown in FIG. 3A, the ball 4 is pushed to move to the introduction portion 6 of the pickup body 2 and the ball 4 is held by the restraining member 7. As shown in FIG. 3B, the flat portion of the bottom portion 10 is placed as shown in FIG. 3B, and the tip is engaged with the restraining member 7 so that the progress is suppressed at this portion.

  However, since the base side of the jumping blade 3 continues to rotate, as shown in FIG. 4A, the jumping blade 3 undergoes elastic deformation that curves backward in the rotation direction, and eventually the tip is detached from the restraining member 7, As shown in FIG. 4 (b), the elastically repelling force deforms to be bent forward in the rotational direction and applies a jumping force to the ball 4. In this case, the jumping distance is the jumping blade. When 3 is formed of a 0.3 mm steel plate, it is 30 to 50 cm, and the ball 4 jumps into the collection container 5 attached to the pick-up machine body 2 with a sufficient surplus force. It has been proved that the operation of catching the ball 4 rolling on the surface 15 by the rotation of 3 and collecting it in the collection container 5 is performed reliably and stably.

  In picking up the ball, a person pushed the handle 18 to propel the picker body 2, but the picker body 2 is equipped with a motor or the like that is operated by a charger, although not shown in the drawing. If the rotating shaft 14 and the wheel 17 are rotated by a motor or the like, the main body of the picker is made to run freely, and a person can obtain a picker that only needs to be operated by the handle 18, and is less fatigued and efficient. An increasing ball picker is obtained.

  The ball picking machine according to the present invention can also collect golf, table tennis, and other balls in the same manner as described above if the balls to be collected change and the specifications and conditions of each part are changed accordingly. Can do.

  In this embodiment, the diving blade 3 of the first embodiment has a flat plate structure as a whole, and one end is attached to the rotating shaft 12, whereas the portion of the diving blade 3 attached to the rotating shaft 12 is close to FIG. As shown in FIG. 5 (a), the plate material is bent to form a bent portion 19 that forms a circular shape, or one leg 20a of the coil spring 20 is joined to one end of the jumping blade 3 as shown in FIG. The other leg 20b is fixed to the rotary shaft 12 so that the coil portion 20c of the coil spring 20 becomes the bent portion 19, and it is impossible to apply force to the bent blade 3 when these bent portions 19 are applied. Therefore, it is preferable that the jumping blade 3 not provided with the bending portion 19 can be easily broken from the vicinity of the mounting portion.

  In this embodiment, the ball 4 is caused to jump by a rotational movement around the attachment portion of the jumping blade 3. Therefore, although the structure of the diving blade 3 is different from that shown in the first embodiment, the structure and operation of the constituent members other than the diving blade 3 are the same as those shown in the first embodiment. Are denoted by the same reference numerals, and descriptions thereof are omitted.

  As shown in FIGS. 7 and 8, the jumping blade 3 used in this embodiment is formed on a single plate of metal or synthetic resin, and one end is attached to the angular cross section of the rotating shaft 12 with a spring hinge 21. The spring hinge 21 used for this attachment has one piece 21a and the other piece 21b connected to the cylindrical portions 21c and 21d alternately attached to the two so as to be rotatable through the shaft 22, and further, the cylindrical portions 21c and 21d The coil spring 23 is disposed with the coil portion 23a fitted on the shaft 22 so that one leg 23b of the coil spring 23 is engaged with one piece 21a of the spring hinge 21, and the other leg 23c is The spring hinge 21 is biased in the opening direction by the coil spring 23 by engaging with the other piece 21 b of the hinge 21.

  The jumping blade 3 is formed with a right-angled bent edge 24 at the end on the attachment side, and a cushion piece 25 formed of rubber or the like is attached to the upper surface of the bent edge 24 so that the cushion material 25 rotates. When the jumping blade 3 is stopped at a position where it hits the angular cross section of the shaft 12 and the rotated jumping blade 3 is returned by the repulsive force of the coil spring 23 of the spring hinge 21, the bent edge 24 is rotated. The impact which collides with 12 is relieved.

  In the ball picking machine 1 having the diving blade 3 configured as described above, when the picking machine main body 2 is advanced toward the ball 4 scattered on the surface 15, the wheel 17 rolls and the diving blade 3 is rotated by the rotating shaft 12. Rotate. For this reason, when the tip of the jumping blade 3 hits the ball 4 as shown in FIG. 9A, the ball 4 is pushed and moved to the introduction portion 6 of the pick-up machine body 2, and the ball 4 is moved to FIG. 9B. As shown in FIG. 1, the flat member is placed on the flat portion of the bottom portion 10 so as not to be held by the restraining member 7, and the tip is engaged with the restraining member 7 and rotation is restrained at this portion.

  However, since the rotation of the rotary shaft 12 continues, the jumping blade 3 rotates around the shaft 22 of the spring hinge 21 in the rotational direction to deform the coil spring 23 as shown in FIG. When the repulsive force is accumulated and the tip of the jumping blade 3 is disengaged from the restraining member 7, the coil spring 23 applies the repulsive force to the jumping blade 3, and the jumping blade 3 is moved as shown in FIG. Since the ball 4 is rotated and a jumping force is applied to the ball 4, the ball 4 is jumped into the collection container 5 and collected.

  It can be used to collect many scattered balls easily and efficiently in tennis or golf practice fields.
