  Preferably, the operating part is arm-shaped. Preferably, the reciprocating operation of the operation unit is a rotation, and the counting unit performs counting when the operation unit is oriented at a predetermined threshold angle by the rotation.

  The turning radius of the operating unit or the threshold angle may be variable.

  The round bar number counter may further include a receiving surface at the edge of the abutting surface on the front side in the relative movement direction so as to gradually move away from the round bar in contact with the abutting surface. Good.

  The present invention related to the counting method of the round bar, the abutment surface of the round bar number counter abuts the top of the round bar in a state where the outer peripheral surfaces are in contact with each other on the conveyance line, This is a round bar counting method in which round bars are counted by relatively moving the contact surface and the round bar.

  Provided are a round bar number counter and a round bar counting method capable of easily and accurately counting the number of round bars.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a plan view showing a round bar number counter 2 according to an embodiment of the present invention. FIG. 2 is a side view of the round bar number counter 2. The round bar number counter 2 includes a counter body 4, a contact portion 6, and an operation portion 8. The contact part 6 is made of a substantially plate-shaped member. The bottom surface 10 of the contact portion 6 is a flat surface.

  The operation unit 8 has an arm shape. The operation unit 8 includes an arm unit 9 and a rotating body 14. The operation unit 8 is attached to the counter body 4. The operation unit 8 is attached to the side surface 12 of the counter body 4. One end of the operating unit 8 is attached to the counter body 4 so as to be rotatable. The other end of the operating unit 8 is a free end. The operation unit 8 has a rotating body 14 at the other end. The rotating body 14 is provided so as to be rotatable with respect to the arm portion 9. The rotation axis z1 of the operating unit 8 and the rotation axis z2 of the rotating body 14 are substantially parallel (see FIG. 1). A rotation plane P <b> 1 of the operation unit 8 is substantially parallel to the side surface 12 of the counter body 4.

  The counter body 4 has a display unit 16. The display unit 16 displays a numerical value with a predetermined number of digits. Although not shown, the counter body 4 has a counting unit. The counting unit is built in the counter body 4. The number of reciprocating motions of the operating unit 8 counted by the counting unit is displayed on the display unit 16. As the structure of the counting unit and the display unit, a known counter structure such as a hand-held counter or a ratchet counter can be adopted. The structures of the counting unit and the display unit 16 are not particularly limited. The structure of the counting unit may be mechanical or electronic. The structure of the display unit 16 may be mechanical or electronic such as a liquid crystal display.

  FIG. 3 shows an example of how the round bar number counter 2 is used while showing one step in the production of the round bar steel material. The round bar number counter 2 is used to count the number of round bar steel members 18. The round steel bars 18 are juxtaposed on the upper surface 22 of the gantry 20. The gantry 20 constitutes a part of a conveying line for the round bar steel material 18. A plurality of round bar steel members 18 arranged in parallel on a plane in contact with each other constitute a round bar steel group 19. The plurality of round steel bars 18 are arranged in parallel so that their longitudinal directions are parallel to each other. The upper surface 22 of the gantry 20 is a flat surface and is slightly inclined. The plurality of round steel bars 18 are arranged in parallel on a plane while being in contact with each other. The plurality of round steel bars 18 have substantially the same outer diameter.

  In the process shown in FIG. 3, a predetermined number of round bar steel members 18 among the round bar steel members 18 arranged in parallel on the upper surface 22 of the gantry 20 are dropped on the transport roller 24. A stopper 26 is provided at the end of the gantry 20. When the stopper 26 is accommodated below, the round bar steel material 18 falls on the transport roller 24 due to gravity. When the necessary number of round bar steel members 18 are dropped onto the conveying roller 24, the stopper 26 is protruded upward to stop the round bar steel members 18 from dropping. In order to drop the necessary number of round bar steel members 18 on the conveying roller 24, accurate counting of the round bar steel members 18 is necessary.

  The round bar number counter 2 is placed on a plurality of round bars arranged in parallel on a plane in contact with each other. The bottom surface 10 of the contact portion 6 contacts the top of the round bar. The bottom surface 10 of the contact portion 6 is a contact surface 28.

  The width of the contact surface 28 (the width in the direction k of the line of intersection between the rotation plane P1 of the operating unit 8 and the plane parallel to the contact surface 28) is defined as a width W (see FIG. 1). The width W is set to be twice or more the outer diameter d of the round steel bar 18. By making the width W more than twice the outer diameter d of the round bar steel material 18, the round bar number counter 2 always has two or more round bar steel materials regardless of the relative positional relationship with the round bar steel group 19. 18, the posture of the round bar counter 2 is stabilized. Stable counting can be performed by the counter 2 for the round bar with a stable posture.

  In counting, the contact surface 28 and the plurality of round bar steel members 18 (that is, the round bar steel member group 19) relatively move while the contact surface 28 is in contact with the top of the round bar steel member 18. For example, the round bar steel group 19 may be fixed, and the round bar number counter 2 may move on the round bar steel group 19. The round bar number counter 2 may be fixed, and the round bar steel group 19 may move.

  The round bar number counter 2 is disposed so that the abutting surface 28 abuts on the top of the round bar steel 18 and the direction k is substantially orthogonal to the longitudinal direction of the round bar steel 18. The relative movement direction of the round bar number counter 2 is a direction substantially orthogonal to the longitudinal direction of the round bar steel 18. This relative movement direction is substantially parallel to the rotation plane P <b> 1 of the operation unit 8.

  The rotating body 14 disposed at the other end of the operating unit 8 contacts the surface (upper surface) of the round bar steel group 19. Due to the relative movement between the round bar number counter 2 and the round bar steel group 19, the rotating body 14 moves up and down following the upper surface of the round bar group 19. Due to this vertical movement, the operation unit 8 rotates. This rotation is a reciprocating motion. The operation unit 8 repeats right rotation and left rotation within a predetermined phase range. Since the rotating body 14 is rotatable, it can smoothly move on the upper surface of the round bar steel group 19. Even when there is a gap between adjacent round steel bars 18, the operation unit 8 can reciprocate, so that the counting by the round bar counter 2 is possible.

  The front in the relative movement direction of the round bar number counter 2 with respect to the round bar steel group 19 is defined as the front m1, and the rear in the relative movement direction of the round bar number counter 2 with respect to the round bar steel group 19 is defined as the rear m2 (see FIG. 3). The round bar number counter 2 is arranged such that the free end side (rotating body 14 side) of the operating unit 8 is located behind the rotational axis z1 side of the operating unit 8 m2.

  The upper surface of the round steel bar group 19 constitutes an uneven surface formed by a semicircular continuous shape. Due to the unevenness, the rotating body 14 moves up and down, and the operation unit 8 reciprocates. The rotating body 14 does not need to follow the upper surface of the round steel bar group 19 completely. The follow-up of the rotating body 14 may be performed to the extent necessary to count the number of round steel bars 18.

  The operation unit 8 is urged to rotate so that the free end side (the rotating body 14) is pressed against the upper surface of the round bar steel group 19. In other words, the operation unit 8 is urged to rotate downward. This biasing is performed by, for example, a torsion spring. By this biasing, the follow-up of the operation unit 8 becomes more reliable. This energization is not essential. For example, the operation unit 8 may be configured to follow the upper surface of the round bar steel group 19 only by gravity.

  When the round bar counter 2 moves relative to the round bar steel group 19, the operating unit 8 reciprocates in a predetermined phase range and rotates. The phase of the operation unit 8 can be specified by, for example, an angle between the longitudinal direction of the operation unit 8 and a plane h parallel to the contact surface 28. An angle θ1, an angle θ2, and an angle θ3, which will be described later, indicate angles formed between the longitudinal direction of the operation unit 8 and a plane h parallel to the contact surface 28.

  When the round bar number counter 2 relatively moves on the round bar steel group 19, the operation unit 8 reciprocates and rotates in the range from the angle θ1 to the angle θ2. When the operating portion 8 has an angle θ1, the rotating body 14 is in contact with the top of the round steel bar 18. When the operating portion 8 has an angle θ2, the rotating body 14 is in contact with a portion other than the top portion of the round bar steel material 18.

  When the operation unit 8 is oriented at a predetermined threshold angle θ3 by the rotation, the counting unit performs counting. The threshold angle θ3 is set between the angle θ1 and the angle θ2. In other words, the relationship of [angle θ1 ≦ threshold angle θ3 ≦ angle θ2] is established. The counting unit performs one count by one reciprocating motion in which the angle of the operating unit 8 reaches from the angle θ1 to the angle θ2 and further returns from the angle θ2 to the angle θ1. The display unit 16 accumulates and displays the numbers counted by the counting unit. The number displayed on the display unit 16 increases by one reciprocating motion when the angle of the operating unit 8 changes from the angle θ1 to the angle θ2 and further returns from the angle θ2 to the angle θ1.

  The round bar number counter 2 is configured so as not to hinder the reciprocating motion of the operating unit 8. In the movement from the angle θ1 to the angle θ2, the members other than the operation unit 8 in the round bar number counter 2 do not interfere with the rotation of the operation unit 8.

  The angle θ1 and the angle θ2 can change depending on various conditions. The angle θ1 can vary depending on, for example, the distance between the rotation axis z1 of the operation unit 8 and the contact surface 28 and the rotation radius R of the operation unit 8 (see FIGS. 4 and 5). The angle θ <b> 2 can vary depending on, for example, the outer diameter of the round steel bar 18 and the turning radius R of the operating unit 8.

  FIG. 4 shows a case where the outer diameter of the round bar steel material 18 is relatively small, and FIG. 5 shows a case where the outer diameter of the round bar steel material 18 is relatively large. Depending on the outer diameter of the round bar steel material 18, it may be necessary to adjust the turning radius R and the threshold angle θ <b> 3 of the operating portion 8. From the viewpoint of expanding the range of the outer diameter d of the round bar that can be counted, it is preferable that the turning radius R of the operating portion 8 is variable. From the viewpoint of expanding the range of the outer diameter d of the round bar that can be counted, it is preferable that the threshold angle θ3 is variable. Since the turning radius R or the threshold angle θ3 is variable, the versatility of the round bar counter 2 is enhanced. In order to make the turning radius R of the operating unit 8 variable, for example, the operating unit 8 may be detachable, or the operating unit 8 may be extendable. Since the operation unit 8 is detachable, the operation unit 8 can be replaced with another operation unit 8 having a different rotation radius R.

  As described above, from the viewpoint of enabling stable counting, the width W is preferably at least twice the outer diameter d of the round bar steel material 18. The width W is preferably variable from the viewpoint of expanding the range of the outer diameter d of the round bar that can be stably counted. In order to make the width W variable, for example, it is preferable that the contact portion 6 is detachable. By making the contact portion 6 detachable, the contact portion 6 having a different width W can be replaced.

  As described above, when the outer diameter d is changed, the angle θ1 and the angle θ2 can be changed. On the other hand, the threshold angle θ3 only needs to be set in a range between the angle θ1 and the angle θ2. As long as the relationship of [angle θ1 ≦ threshold angle θ3 ≦ angle θ2] is satisfied, even if the angle θ1 or the angle θ2 changes, it is not necessary to change the threshold angle θ3. Therefore, even if the turning radius R and the threshold angle θ3 are fixed, the range of the outer diameter d of the round bar that can be measured by the round bar counter 2 is wide. In the experiment of the present inventor, a round bar having an outer diameter d in the range of 18 mm to 95 mm can be counted by the single specification round bar counter 2 having a constant value such as the turning radius R and the threshold angle θ3. It was confirmed.

  From the viewpoint of suppressing erroneous counting, the threshold angle θ3 is more preferably larger than the angle θ1, more preferably [θ1 × 1.1] or more, and [θ1 × 1.2] or more. It is particularly preferred. From the viewpoint of suppressing erroneous counting, the threshold angle θ3 is more preferably smaller than the angle θ2, more preferably [θ2 × 0.9] or less, and [θ1 × 0.8] or less. It is particularly preferred.

  The round bar counter 2 can be carried and can be easily used at a desired site.

  FIG. 6 is a view showing a usage state of the round bar counter 29 according to the modification. The configuration of the round bar number counter 29 is the same as that of the round bar number counter 2 described above except for the most upstream part 6a described later. In FIG. 6, the same reference numerals as those in FIG. 3 are given to the same components as the round bar number counter 2 and the usage state thereof, and description thereof is omitted as appropriate.

  A most upstream portion 6 a is provided on the upstream side of the contact portion 6 of the round bar number counter 29. The upstream side means the upstream side of the round steel bar conveying line. In FIG. 6, the left side is the upstream side and the right side is the downstream side. The most upstream part 6 a is provided on the front side in the relative movement direction of the contact part 6. In the usage pattern of FIG. 6, the front side m1 in the relative movement direction coincides with the upstream side of the transport line. The most upstream part 6 a is provided to be bent or curved from the upstream edge part of the contact part 6. The direction of this bending or bending is the opposite side to the round bar steel material arrangement side. When the round bar steel material is disposed below the round bar number counter 29, the bending or bending direction is the upper side. In addition, the contact part 6 and the most upstream part 6a are integral.

  The bottom surface (outer surface) of the most upstream portion 6a is adjacent to the bottom surface 10 of the contact portion 6 (that is, the contact surface 28). The bottom surface (outer surface) of the most upstream part 6 a constitutes a receiving surface 30. The receiving surface 30 extends so as to gradually move away from the round bar 32 in contact with the contact surface 28 at the edge of the contact portion 6 on the front side in the relative movement direction. In the state of use as shown in FIG. 6 in which the round bars are arranged below, the receiving surface 30 is inclined so as to rise from the downstream side to the upstream side of the transport line. The receiving surface 30 may be a flat surface or a curved surface.

  The receiving surface 30 has the following effects. As shown in FIG. 6, when a round bar 34 having an outer diameter larger than that of the round bar 32 being counted flows from the upstream side of the transport line, the receiving surface 30 comes into contact with the top round bar 34. By this contact, the round bar number counter 29 is smoothly transferred onto the thicker round bar 34. By the receiving surface 30, the round bar number counter 29 smoothly moves from the top of the round bar 32 to the top of the round bar 34 having a larger outer diameter. When the transition is made to the round bar having a larger outer diameter by the receiving surface 30, it is not necessary to reset the round bar number counter 29 or stop the transport line. Repositioning or stopping the line can increase the counting time and induce counting errors. The receiving surface 30 facilitates continuous counting of round bars having different outer diameters, and increases the counting accuracy.

  The reciprocating motion of the operating part may not be rotation. For example, the reciprocating motion of the operating unit may be a linear motion. In this case, a push button type or the like may be exemplified as the operation unit. On the other hand, the above-described embodiment in which the reciprocating motion of the operating part is turned is preferable in that the reciprocating motion of the operating part can be easily smoothed and the counting accuracy can be increased.

  The present invention can be applied to counting various round bars as well as round steel bars.
