[Best Mode-1]
Here, FIG. 1 is a side view of the sphere transport device, FIG. 2 is a perspective view of the sphere transport device, FIG. 3 is a side view of the sphere transport device with an increased transport distance, and FIG. 4 is a sphere transport with the transport direction changed. It is a side view which shows an apparatus.

  In the figure, a sphere transport device is a device that transports a sphere a in the vertical direction, and a sphere transport path 1 serving as a transport path for transporting the sphere a is formed in the vertical direction. On one side of the sphere conveyance path 1, a plurality of drive rollers 2, for example, two in FIG. 1 and FIG. 2 and five in FIG. Each drive roller 2 is arranged in parallel up and down. The lowermost drive roller 2a, the uppermost drive roller 2b, and the intermediate drive roller 2c are all of the same shape.

  The driving roller 2 has a cylindrical shape, and the cylindrical peripheral surface is in contact with the sphere a. The driving roller 2 is placed horizontally. Both ends of the drive roller 2 placed horizontally are respectively supported by bearings (not shown) constituting both sides of the spherical body transporting device. The drive roller 2 is arranged so as to rotate around a horizontal axis.

  The upper and lower drive rollers 2 are interlocked and connected to a roller drive motor (not shown), and rotate in the same direction by driving the roller drive motor so that the spherical body a cooperates with the concave arc-shaped fixed wall 3 in cross section and faces upward. Or it conveys downward.

  On the opposite surface of the driving roller 2 on the other side of the spherical conveying path 1, a concave arc having a cross section in which the width of the spherical conveying path 1 is maintained at a constant interval with the side peripheral surface of the cylindrical driving roller 2. A plurality of mold fixing walls 3 are arranged in the vertical direction, for example, two in FIGS. 1 and 2 and five in FIG. The center of curvature of the concave arc of the concave arc-shaped fixed wall 3 in the cross section coincides with the rotation center of the driving roller 2 facing each other, and the width of the spherical transport path 1 is kept constant.

  Since the force for sandwiching the sphere a uses an elastic force and a frictional force, when the material of the sphere a is a soft elastic material, for example, in the case of a tennis ball, the surface material of the driving roller 2 may be a hard material, but the sphere a is a hard material. For example, in the case of a golf ball, the surface material of the driving roller 2 uses a soft elastic material to increase the contact area and frictional force between them.

  Between the lower surface of the lowermost drive roller 2a, which is the lower end side of the spherical transport path 1, and the lower end of the lowermost section-shaped concave arc-shaped fixed wall 3a, it is an intake side for upward transport, and is suitable for downward transport.

Further, the lowermost surface of the lowermost drive roller 2a is adjusted so that the gap with the floor surface is slightly smaller than the diameter of the sphere a.

  Similarly, between the rearmost end surface of the uppermost drive roller 2b on the upper end side of the spherical transport path 1 and the upper end of the uppermost concave arc-shaped fixed wall 3a on the uppermost section, it is the intake side in the downward transport, In the upward conveyance, a spherical upper portion entrance / exit portion 1b serving as a take-out side is formed. The upper and lower spherical portion 1b faces upward.

  Further, in the sphere transport device shown in FIG. 4, the sphere a is transported by bypassing the obstacle, and is transported by changing the direction of movement of the sphere a. A lower straight portion 1c, a detour portion 1d, and an upper straight portion 1e are formed from the lower side toward the upper side. As shown in FIGS. 1 to 3, a lower sphere entrance / exit portion 1a is formed on the lower end side of the sphere conveyance path 1 shown in FIG. 4, and an upper sphere entrance / exit portion 1b is formed on the upper end side.

  The lower straight portion 1c of the spherical body conveyance path 1 is formed in a straight line shape directly upward from the floor surface. In the drawing, two drive rollers 2d, 2e and two concave arc-shaped fixed walls 3d, 3e are arranged in the vertical direction. The upper cross-section concave arc-shaped fixed wall 3e extending from the lower straight portion 1c to the detour portion 1d has a short arc length. The upper drive roller 2e corresponding to the upper cross-section concave arc-shaped fixed wall 3e is disposed on a diagonally lower extension line of a later-described drive roller 2f disposed in the detour portion 1d. The lower part entrance / exit part 1a of the sphere is formed on the lower end side between the driving roller 2d and the fixed wall 3d having a concave cross section.

  On the upper side of the lower straight portion 1c, a spherical body conveyance path 1 of a detour portion 1d is formed. The detour portion 1d extends in a slanting right upward direction in the drawing and ends in a slanting upward leftward direction from the intermediate position. Two drive rollers 2f are disposed obliquely on the upper side of the portion extending obliquely to the upper right in the drawing, and two cross-section concave arc-shaped fixed walls 3f are disposed on the lower oblique side. One drive roller 2k is arranged at an intermediate position on the extension of the direction. In the drawing, two drive rollers 2g are arranged to be inclined to the left diagonally upward direction in the drawing and extend in a diagonally upward leftward direction from the intermediate position, and a concave arc is formed on the upper side. Two concave arcuate fixed walls 3g are arranged obliquely upward and to the left.

  Corresponding to the driving roller 2k at the intermediate position, a concave arc-shaped fixed wall 3k in the cross section is arranged in the vertical direction on the right side in the drawing, and a concave arc in the cross section is inclined to the upper right in the downward direction. A mold fixing wall 3m is disposed, and a concave arcuate mold fixing wall 3n having a concave arc shape is disposed on the upper side of the mold fixing wall 3n so as to be inclined obliquely upward to the left. Note that these three cross-section concave arc-shaped fixed walls 3k, 3m, and 3n may be formed on the same arc and formed by one cross-section concave arc-shaped fixed wall.

The sphere conveyance path 1 of the upper straight portion 1e is formed again in the direction directly above the portion where the detour portion 1d ends. In the drawing, three drive rollers 2h, 2i, 2j and three concave-arc-shaped fixed walls 3h, 3i, 3j are arranged in the vertical direction. The lower cross-section concave arc-shaped fixed wall 3h continuous from the detour portion 1d to the upper straight portion 1e has a short arc length. The lower drive roller 2h corresponding to the lower cross-section concave arc-shaped fixed wall 3h is disposed on an obliquely upper extension line of the drive roller 2g disposed in the detour portion 1d. On the upper end side between the driving roller 2j and the arc-shaped fixed wall 3j having a concave cross section, the upper and lower spherical portion 1b is formed.

Next, the operation based on the configuration of the best mode-1 for carrying out the invention will be described below.
In the sphere conveying device shown in FIGS. 1 to 3, the lowermost driving roller 2a entrains and picks up the sphere a from the sphere lower entrance portion 1a on the floor surface side and clamps it on the concave arc-shaped fixed wall 3a. In FIG. 1 and FIG. 2, the rotational force causes the drive roller 2b (the drive roller 2c in FIG. 3) to move upward. Next, in FIG. 1 and FIG. 2, the sphere a is moved upward by a rotational force while being sandwiched between the driving roller 2b and the concave arc-shaped fixed wall 3b. The length of the arc of the concave arc-shaped fixed wall 3 is determined by the radius of the driving roller 2, the diameter of the sphere a, and the moving direction of the sphere a. In the spherical body conveying apparatus shown in FIG. 3, the spherical body a is conveyed upward to a desired position while repeating this between the intermediate driving roller 2c and the concave arc-shaped fixed wall 3c. The sphere a transported in the sphere transport path 1 moves upward while rotating. The sphere a transported upward is discharged from the sphere upper entrance / exit 1b. When transporting upward, each drive roller 2 rotates counterclockwise in the direction of the arrow in the drawing.

On the other hand, when the sphere a is transported downward, when the sphere a is inserted into the sphere upper entrance / exit portion 1b, the uppermost driving roller 2b entrains the sphere a and sandwiches it between the arc-shaped fixed walls 3b having a concave cross section. 1 and 2 is moved down to the driving roller 2a (the driving roller 2c in FIG. 3) while being pressed. Next, in FIGS. 1 and 2, the sphere a is moved downward by the rotational force while being clamped by the driving roller 2a and the concave arc-shaped fixed wall 3a. The length of the arc of the concave arc-shaped fixed wall 3 is determined by the radius of the driving roller 2, the diameter of the sphere a, and the moving direction of the sphere a. In the sphere conveyance device shown in FIG. 3, the sphere a is conveyed downward to a desired position while repeating this between the intermediate driving roller 2c and the concave arc-shaped fixed wall 3c. The sphere a transported in the sphere transport path 1 moves downward while rotating. The spherical body a conveyed downward is discharged | emitted from the spherical lower part entrance / exit part 1a. When transporting downward, each drive roller 2 rotates in the clockwise direction opposite to the arrow direction in the drawing.

  Further, in the spherical body conveying apparatus shown in FIG. 4, the lowermost driving roller 2d takes up and picks up the spherical body a from the spherical lower portion entrance / exit portion 1a on the floor side, and rotates while pinching the concave circular arc shaped fixed wall 3d. The lower straight portion 1c is moved up to the drive roller 2e by force. Next, the spherical body a is inclined and moved to the detour portion 1d by the rotational force while being pinched by the driving roller 2e and the concave arcuate fixed wall 3e. The sphere a that has reached the detour portion 1d is sandwiched between the driving roller 2f and the arc-shaped fixed wall 3f having a concave cross section, and is rotated diagonally upward to the driving roller 2k at the intermediate position by the rotational force in the sphere conveyance path 1 of the detour portion 1d. Tilt to move. At an intermediate position, the sphere a changes its moving direction from a right diagonally inclined upward movement to a reverse left diagonally inclined upward movement by rotational force while being pinched between the driving roller 2k and the concave arc-shaped fixed walls 3m, 3k, 3n, While being pinched by the drive roller 2g and the concave arc-shaped fixed wall 3g, the rotational force causes the spherical conveying path 1 of the detour portion 1d to move obliquely upward to the left from the drive roller 2k at the intermediate position to the lower portion of the upper straight portion 1e. To do. The sphere a that has reached the lower portion of the upper straight portion 1e is lifted and moved upward by a rotational force while being sandwiched between the driving roller 2h and the concave arcuate fixed wall 3h, and the driving rollers 2i and 2j of the upper straight portion 1e. And the spherical conveying path 1 between the arcuate fixed walls 3i and 3j having a concave cross section are lifted and moved directly upward by a rotational force while being pinched. The length of the arc of the concave arc-shaped fixed wall 3 is determined by the radius of the driving roller 2, the diameter of the sphere a, and the moving direction of the sphere a. The sphere a transported in the sphere transport path 1 moves upward while rotating. The sphere a transported upward is discharged from the sphere upper entrance / exit 1b. When transporting upward, each drive roller 2 rotates counterclockwise in the direction of the arrow in the drawing.

On the other hand, when the sphere a is transported downward, when the sphere a is inserted into the sphere upper entrance 1b, the uppermost drive roller 2j entrains the sphere a and sandwiches it between the concave arcuate fixed walls 3j having a cross section. While pressing, the upper straight portion 1e is moved down to the driving roller 2h by the rotational force. Next, the spherical body a is inclined and moved down to the detour portion 1d by the rotational force while being clamped by the driving roller 2h and the concave arc-shaped fixed wall 3h. The sphere a that has reached the detour portion 1d is sandwiched between the driving roller 2g and the concave arc-shaped fixed wall 3g of the cross section, and is rotated diagonally downward to the left in the sphere conveyance path 1 of the detour portion 1d to the driving roller 2k at the intermediate position by the rotational force. Tilt to move. At the intermediate position, the sphere a changes its moving direction from a right slanting downward movement to a reverse left slanting slanting downward movement by a rotational force while being sandwiched between the driving roller 2k and the concave arc-shaped fixed walls 3n, 3k, 3m in cross section, While being pinched between the driving roller 2f and the concave arc-shaped fixed wall 3f, the rotational force causes the spherical portion 1d of the detour portion 1d to move obliquely downward to the left from the driving roller 2k at the intermediate position to the upper portion of the lower straight portion 1c. To do. The sphere a that has reached the upper portion of the lower straight portion 1c is moved downward to the driving roller 2d directly below and the concave arcuate fixed wall 3d by the rotational force while being sandwiched between the driving roller 2e and the concave arcuate fixed wall 3e. . The length of the arc of the concave arc-shaped fixed wall 3 is determined by the radius of the driving roller 2, the diameter of the sphere a, and the moving direction of the sphere a. The sphere a transported in the sphere transport path 1 moves downward while rotating. The spherical body a conveyed downward is discharged | emitted from the spherical lower part entrance / exit part 1a. When transporting downward, each drive roller 2 rotates in the clockwise direction opposite to the arrow direction in the drawing.

[Best Mode-2]
Here, FIG. 5 is a side sectional view of the sphere collection device, FIG. 6 is a side view of the sphere collection device, and FIG. 7 is a plan view of the sphere collection device.

  In the figure, a sphere collection device is a device that collects spheres a such as golf balls scattered on the ground while moving. The sphere collection device is provided with a sphere collection chamber 11 for accommodating the collected sphere a. The sphere collection chamber 11 has, for example, a box shape, and an inclined plate 11 a that is inclined downward toward the rear is attached to the bottom surface inside the sphere collection chamber 11 and is accommodated in the sphere collection chamber 11. The spherical body a is moved rearward by the inclined plate 11a and accumulated. Further, a net or the like for preventing the collected sphere a from jumping out is provided on the upper surface of the sphere collection chamber 11.

  Drive wheels 12 a are respectively attached to the outer front sides of the left and right side surfaces of the spherical body collection chamber 11. Further, non-driven caster type rear wheels 12b are respectively attached to the rear side outside the left and right side surfaces of the spherical body collection chamber 11. The left and right drive wheels 12a are linked to a drive wheel motor 13 disposed on the lower side of the inclined plate 11a, and are rotated by driving the drive wheel motor 13 to move the sphere collection device.

  A sphere transport path 1 serving as a transport path for sending the recovered sphere a to the recovery chamber 11 is formed upward at the front of the sphere recovery chamber 11. A plurality of, for example, two drive rollers 2 are arranged in the vertical direction on one side of the spherical body conveyance path 1, that is, on the front side in the drawing.

  The driving roller 2 has a cylindrical shape, and the cylindrical peripheral surface is in contact with the sphere a. The drive roller 2 is placed horizontally in the left-right width direction of the sphere collection chamber 11. Both ends of the horizontally placed driving roller 2 are respectively supported by bearings (not shown) that protrude to the front sides of the left and right sides of the sphere collection chamber 11. The drive roller 2 is disposed so as to rotate about a horizontal axis in the width direction of the sphere collection chamber 11.

  The upper and lower drive rollers 2 are linked to a roller drive motor 14 installed on the lower side of the sphere collection chamber 11, and are rotated by driving of the roller drive motor 14 to cause the sphere a to have a concave arc-shaped fixed wall 3 having a concave cross section. In this way, the ball is transported upward and is fed into the sphere collection chamber 11 in cooperation.

  The opposite surface of the driving roller 2 on the other side of the spherical conveying path 1, that is, the width of the conveying path on the side of the spherical body collecting chamber 11 in the drawing is a constant distance from the side peripheral surface of the cylindrical driving roller 2. A plurality of, for example, two arcuate fixed walls 3 having a concave cross-section to be maintained are arranged vertically. The center of curvature of the concave arc of the concave arc-shaped fixed wall 3 in cross section coincides with the center of rotation of the driving roller 2 facing each other, and the width of the conveyance path is kept constant.

  The sphere stop plate 15 is a plate that prevents the sphere a fed into the sphere collection chamber 11 through the sphere conveyance path 1 from jumping forward, and is a tangential upper portion of the rearmost end of the circular side peripheral surface of the upper drive roller 2b. Attached vertically to the side.

  Since the force for sandwiching the sphere a uses an elastic force and a frictional force, when the material of the sphere a is a soft elastic material, for example, in the case of a tennis ball, the surface material of the driving roller 2 may be a hard material, but the sphere a is a hard material. For example, in the case of a golf ball, the surface material of the driving roller 2 uses a soft elastic material to increase the contact area and frictional force between them.

  A sphere take-in portion 16 is formed between the lower surface of the lowermost drive roller 2a on the lower end side of the sphere conveyance path 1 and the lower end of the lowermost cross-section concave arc-shaped fixed wall 3a. The sphere taking-in part 16 faces the ground. The sphere a on the ground can be taken in smoothly. Further, the lowermost surface of the lowermost drive roller 2a is adjusted such that the gap with the ground is slightly smaller than the diameter of the sphere a.

  In front of the driving roller 2, that is, in front of the sphere conveyance path 1, a sphere scraping device 17 that scrapes out the sphere a entering the concave portion of the ground and discharges it toward the sphere capturing portion 16 at the rear is arranged to be movable up and down. Yes.

  The spherical scraping device 17 includes a drive shaft 17a extending in the left-right width direction, a plurality of arcuate scraping blades 17b attached to the drive shaft 17a, and a pair of arms 17c that supports both ends of the drive shaft 17a to be movable up and down. , And a scraping drive motor 17d for rotating the drive shaft 17a. The drive shaft 17a is linked to a scraping drive motor 17d through a transmission chain 17e.

The base end side of the arm 17c is rotatably supported by the upper part of the front side of the left and right side surfaces of the sphere collection chamber 11, and the arm 17c rotates in the vertical direction around the base end side. This is a mechanism for raising and lowering the drive shaft 17a that supports the motor. Further, each of the raking blades 17b is attached to the drive shaft 17a so that the concave portion faces rearward with the arcuate direction of the raking blades 17b facing downward so that the sphere a is scraped.

Next, the operation based on the configuration of the best mode-2 for carrying out the invention will be described below.
A scraping blade 17b constituting the spherical scraping device 17 in front of the driving roller 2 is rotated by the power of the scraping driving motor 17d, and moves the spherical body a such as a golf ball toward the driving roller 2a. The sphere scraping device 17 works to scrape out the sphere a entering the concave portion of the ground and to give the sphere an initial speed to help the drive roller 2a pick up. In the area where the ground is leveled, the spherical scraping device 17 raises and stores the base end side as the center of rotation.

  The driving roller 2a entrains and picks up the sphere a from the sphere taking-in part 16 from the floor surface or the ground, and lifts the sphere a up to the driving roller 2b by a rotational force while being pressed by the concave arc-shaped fixed wall 3a. The taken sphere a moves upward while rotating in the sphere conveyance path 1.

  Next, the sphere a is raised by a rotational force while being sandwiched between the driving roller 2 b and the concave arc-shaped fixed wall 3 b in cross section, and dropped into the sphere collection chamber 11. At this time, the sphere a is prevented from jumping forward when discharged from the driving roller 2 b by the sphere stopper plate 15, and is prevented from jumping outside by a net or the like stretched on the upper surface of the sphere collection chamber 11. It is. The sphere a dropped and accommodated in the sphere collection chamber 11 rolls on the inclined plate 11a, moves to the rear side, and is accumulated.

  It should be noted that the rotational speed of the drive roller 2 is appropriately about twice the peripheral speed of the drive wheel 12a. The peripheral speed of rotation of the raking blade 17b is appropriately about twice the peripheral speed of the drive wheel 12a.

  The present invention is not limited to the best mode for carrying out the invention, and it goes without saying that various modifications can be made without departing from the spirit of the invention.
