Description

[Technical Field]

[0001] The present invention relates to a reinforcement height adjustment mechanism. [Background technology]

[0002] Conventionally, when manufacturing rebar mesh units in which rebars are arranged, assembly work has generally been performed based on construction drawings. Rebar mesh units are manufactured by placing the rebars one by one, mainly by manual labor. When handling large-diameter or long rebars in large-scale construction projects, depending on the type of rebar, the weight of each rebar can be heavy, and multiple workers must transport each rebar to the designated location and perform the rebar placement work. Because this work is extremely labor-intensive, in some cases, rebar placement work is performed using rebar placement devices or rebar placement robots (see Patent Documents 1, 2, and 3 listed below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 1-75131 [Patent Document 2] Japanese Patent Application Publication No. 1-75132 [Patent Document 3] Japanese Patent Application Publication No. 4-347264 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the height at which the reinforcing bars are arranged is always treated as a constant height, there is a problem in that it cannot handle cases where the reinforcing bar arrangement heights are different for multiple straight bars, such as in reinforcing bar units in which multiple straight bars are arranged perpendicular to curved bars.

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and provides a reinforcement height adjustment mechanism that can arrange multiple reinforcing bars with different reinforcement heights from a constant height. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following means. In other words, the reinforcement height adjustment mechanism of the present invention comprises a reinforcement mechanism that arranges multiple reinforcing bars at different heights, a height detection mechanism that detects the reinforcement height of each of the multiple reinforcing bars, and an up / down movement mechanism that moves the reinforcement mechanism in the up / down direction depending on the detection result of the height detection mechanism.

[0007] In the reinforcement height adjustment mechanism configured in this manner, the height detection mechanism detects the reinforcement height of each of the multiple reinforcing bars. The vertical movement mechanism moves the reinforcement mechanism up and down depending on the detection result of the height detection mechanism. The reinforcement mechanism that has moved up and down places reinforcement from a predetermined height. Therefore, multiple reinforcing bars with different reinforcement heights can be placed from a constant height.

[0008] In the reinforcement height adjustment mechanism according to the present invention, the height detection mechanism may be provided in the reinforcement mechanism.

[0009] In the reinforcement height adjustment mechanism configured in this way, the height detection mechanism is provided in the reinforcement mechanism. Therefore, when the reinforcement mechanism moves to the reinforcement location, the height detection mechanism also moves and detects the reinforcement height, so that the reinforcement height can be detected efficiently.

[0010] Furthermore, the reinforcement height adjustment mechanism according to the present invention may include a guide portion arranged corresponding to the reinforcement height, and the height detection mechanism may have a roller portion movable along the guide portion.

[0011] In the reinforcement height adjustment mechanism configured in this way, the roller part of the height detection mechanism can move along the guide part arranged corresponding to the reinforcement height. Therefore, as the reinforcement mechanism moves to the reinforcement location, the roller part moves along the guide part, allowing for smooth movement of the height detection mechanism.

[0012] In addition, in the reinforcement height adjustment mechanism of the present invention, the height detection mechanism may have a detected part that can move together with the roller part, and a sensor that is fixed to the reinforcement mechanism and detects the height of the detected part.

[0013] In the reinforcement height adjustment mechanism configured in this way, the sensor fixed to the reinforcement mechanism detects the height of the detection part that moves together with the roller part. Therefore, the reinforcement height can be detected by detecting the height of the detection part that moves as the reinforcement mechanism moves to the reinforcement location.

[0014] In addition, in the reinforcement height adjustment mechanism of the present invention, the sensor may have an upper sensor and a lower sensor arranged below the upper sensor, and the up-down movement mechanism may move the reinforcement mechanism in the vertical direction to a height at which both the upper sensor and the lower sensor can detect the detection part.

[0015] In the reinforcement height adjustment mechanism configured in this way, the vertical movement mechanism moves the reinforcement mechanism up and down to a height where both the upper and lower sensors can detect the detection part. Therefore, by moving the reinforcement mechanism up and down depending on the relative vertical positions of the upper and lower sensors and the detection part, multiple rebars with different reinforcement heights can be placed from a constant height.

[0016] In addition, in the reinforcement height adjustment mechanism of the present invention, the height detection mechanism has a support part fixed to the reinforcement mechanism and a sliding part that can slide in the vertical direction relative to the support part, and the roller part and the detected part may be provided on the sliding part.

[0017] In the reinforcement height adjustment mechanism configured in this manner, the roller unit and the detected unit are provided on a sliding unit that can slide up and down relative to the support unit fixed to the reinforcement mechanism, thereby allowing the support unit fixed to the reinforcement mechanism to move smoothly up and down relative to the roller unit and the detected unit.

[0018] In addition, the reinforcement height adjustment mechanism of the present invention may have a through hole formed in the support part that penetrates in the vertical direction, and the sliding part may be inserted into the through hole so as to be slidable in the vertical direction.

[0019] In the reinforcement height adjustment mechanism configured in this way, the sliding part is inserted into a through-hole formed in the support part so as to penetrate the support part in the vertical direction so as to be movable in the vertical direction, and therefore the support part is reliably guided in the vertical direction by the sliding part. [Effects of the Invention]

[0020] According to the reinforcing bar height adjustment mechanism of the present invention, a plurality of reinforcing bars having different reinforcing bar heights can be arranged from a constant height. [Brief explanation of the drawings]

[0022] A reinforcement height adjusting mechanism according to one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a reinforcement device equipped with a reinforcement height adjustment mechanism according to one embodiment of the present invention. As shown in FIG. 1, the reinforcement arrangement device 100 includes a reinforcement stand 1, a curved reinforcement arrangement device 2, and a straight reinforcement arrangement device 3.

[0023] Fig. 2 is a perspective view showing a reinforcing bar unit arranged by the reinforcing bar arrangement device 100. Fig. 3 is a plan view showing a reinforcing bar unit arranged by the reinforcing bar arrangement device 100. As shown in Figures 2 and 3, the length direction of the curved reinforcement A along the horizontal direction is defined as the curved reinforcement direction X, and the length direction of the straight reinforcement B along the horizontal direction is defined as the straight reinforcement direction Y. The curved reinforcement direction X and the straight reinforcement direction Y are perpendicular to each other. The reinforcement arrangement device 100 arranges a reinforcing bar unit C in which multiple curved reinforcement A and multiple straight reinforcement B are perpendicular to each other. The multiple curved reinforcement A are arranged at intervals in the straight reinforcement direction Y. The multiple straight reinforcement B are arranged at intervals in the curved reinforcement direction X.

[0024] As shown in FIG. 1, the reinforcement frame 1 has a support base 10, a curved reinforcement support base 11, and a straight reinforcement support base 16.

[0025] The support base 10 is installed on an installation surface. The support base 10 has a framework shape with a lattice formed inside the four-sided frame, for example, made up of multiple members extending in the curved muscle direction X and multiple members extending in the straight muscle direction Y.

[0026] The curved bar support stand 11 has multiple curved bar support members 12. The curved bar support members 12 are linear members extending in the linear bar direction Y. The curved bar support members 12 are supported by a support base 10. The multiple curved bar support members 12 are arranged at intervals in the curved bar direction X. Since the curved bar A has a shape that is convex toward the center and upward in the curved bar direction X, among the multiple curved bar support members 12, the curved bar support members 12 arranged toward the center of the curved bar direction X are arranged higher than the curved bar support members 12 arranged at the end sides of the curved bar direction X. The curved bar support members 12 have multiple downwardly recessed grooves 12a formed at intervals in the linear bar direction Y. The curved bars A are placed in the grooves 12a.

[0027] The straight bar support stand 16 has multiple straight bar support members 17. The straight bar support members 17 are curved members that extend in the curved bar direction X and convex upward. The straight bar support members 17 are supported by the support base 10. The multiple straight bar support members 17 are arranged at intervals in the straight bar direction Y. The straight bar support members 17 have multiple downwardly recessed grooves 17a formed at intervals in the curved bar direction X. Straight bars B are placed in the grooves 17a.

[0028] The curved reinforcement arrangement device 2 can move the support base 10 in the straight reinforcement direction Y. The curved reinforcement arrangement device 2 moves from the position shown in FIG. 1 to one side Y1 in the straight reinforcement direction Y to the start point 1A, and then moves to the other side Y2 in the straight reinforcement direction Y, while arranging curved reinforcement A in the groove 12a of the curved reinforcement receiving member 12.

[0029] The straight reinforcing bar arrangement device 3 can move the support base 10 in the curved reinforcing bar direction X. The straight reinforcing bar arrangement device 3 moves from the position shown in Fig. 1 to one side X1 in the curved reinforcing bar direction X to the start point 1A, and then moves to the other side X2 in the curved reinforcing bar direction X while placing straight reinforcing bars B in the grooves 17a of the straight reinforcing bar receiving member 17. Note that the straight reinforcing bar arrangement device 3 may be configured to arrange straight reinforcing bars B, and then the curved reinforcing bar arrangement device 2 may arrange curved reinforcing bars A.

[0030] Fig. 4 is a perspective view of the linear reinforcing bar arrangement device, Fig. 5 is a side view showing the movement of the linear reinforcing bar arrangement device, and Fig. 6 is an enlarged side view of the linear reinforcing bar arrangement device. The mechanisms provided in the curved reinforcing bar arrangement device 2 and the straight reinforcing bar arrangement device 3 will be explained using the drawing of the straight reinforcing bar arrangement device 3. As shown in Fig. 4, the curved reinforcing bar arrangement device 2 and the straight reinforcing bar arrangement device 3 each include a device main body 20, a reinforcing bar placing section 21, a reinforcing bar push-up section (not shown), a reinforcing bar delivery section 23, a reinforcing bar temporary placement section 25 (see Fig. 6), a staggered adjustment device (not shown), and a reinforcing bar height adjustment mechanism 4. The curved reinforcing bar arrangement device 2 does not necessarily have to include the reinforcing bar height adjustment mechanism 4.

[0031] The device main body 20 is movable in the curved bar direction X relative to the support base 10. A plurality of straight bars B can be placed on the upper side of the reinforcing bar placing section 21. The straight bars B placed on the reinforcing bar placing section 21 have not yet been arranged by the reinforcing bar height adjustment mechanism 4. The reinforcing bar placing section 21 is configured to arrange the plurality of straight bars B close to one side X1. For example, the reinforcing bar placing section 21 has an axis oriented in the straight bar direction Y and is equipped with a conveyor that rotates so that the upper side moves to one side X1.

[0032] The reinforcing bar push-up unit is movable upward and downward and pushes upward the straight bars B that are positioned nearest to one side X1 among the plurality of straight bars B placed on the reinforcing bar placing unit 21.

[0033] The upper surface of the reinforcing bar feed-out section 23 is gradually inclined downward as it approaches the one side X1. The straight bar B pushed up by the reinforcing bar push-up section moves by rolling along the upper surface of the reinforcing bar feed-out section 23 toward the one side X1.

[0034] As shown in Figure 6, the rebar temporary restraints 25 are capable of receiving the straight rebars B that have rolled over the top surface of the rebar delivery section 23. A plurality of the rebar temporary restraints 25 are arranged at intervals in the straight rebar direction Y. The straight rebars B are stretched between the plurality of the rebar temporary restraints 25. A staggered adjustment device (not shown) adjusts the position of the straight rebars B in the straight rebar direction Y.

[0035] The reinforcing bar height adjustment mechanism 4 scoops up the straight reinforcing bars B placed on the reinforcing bar temporary placement section 25 and arranges them in a predetermined position. The reinforcing bar height adjustment mechanism 4 includes a guide member (guide section) 30, a reinforcing bar arrangement mechanism 40, a height detection mechanism 50, and a vertical movement mechanism 60 (see FIG. 9).

[0036] As shown in Fig. 1, the guide members 30 are arranged corresponding to the height of the multiple straight reinforcements B to be arranged. The guide members 30 are curved members that extend in the curved reinforcement direction X and are convex upward. The guide members 30 are supported by a support base 10.

[0037] As shown in Figure 6, the reinforcement mechanism 40 places straight reinforcing bars B in the grooves 17a of the straight reinforcing bar receiving member 17. Because the straight reinforcing bar receiving member 17 has an upwardly convex curved shape, the height of the multiple straight reinforcing bars B to be placed depends on the height of the grooves 17a of the straight reinforcing bar receiving member 17. The reinforcement mechanism 40 places the multiple straight reinforcing bars B at different heights.

[0038] As shown in Fig. 4, the reinforcement mechanism 40 has a plurality of reinforcement members 41 and a plurality of connecting members 41a. The plurality of reinforcement members 41 are arranged at intervals in the linear reinforcement direction Y. The connecting members 41a connect adjacent reinforcement members 41. The plurality of reinforcement members 41 can operate synchronously by being connected by the connecting members 41a.

[0039] The reinforcing bar 41 includes a conveyor support portion 42 , a pair of upper and lower gears 43 , 43 , a conveyor 44 , and a plurality of gripping members 45 .

[0040] The conveyor support part 42 is a member that is long in the vertical direction. A pair of gears 43, 43 are provided on the upper and lower parts of the conveyor support part 42. The gear 43 is connected to the conveyor support part 42 so as to be rotatable around an axis that is in the linear line direction Y. The gear 43 is rotatable clockwise when viewed from one side Y1. The conveyor 44 is wound around the pair of gears 43, 43. As the pair of gears 43, 43 rotate, the conveyor 44 is also rotatable clockwise when viewed from one side Y1.

[0041] As shown in Fig. 6, multiple gripping members 45 are fixed at intervals in the longitudinal direction of the conveyor 44. The position and orientation of the gripping members 45 change as the conveyor 44 rotates. The gripping members 45 have a pair of claws 46, 47. The pair of claws 46, 47 protrude in a direction away from the conveyor 44. The protruding length of the claw 46 is longer than the protruding length of the claw 47.

[0042] FIG. 7 is a perspective view showing the height detection mechanism 50. As shown in FIG. As shown in Fig. 7, the height detection mechanism 50 detects the height of each of the multiple straight reinforcing bars B. The height detection mechanism 50 is provided on the other side Y2 of the straight reinforcing bar arrangement device 3. The installation position of the height detection mechanism 50 can be set appropriately. The height detection mechanism 50 has a connecting member 51, a sensor 52, a support member (support portion) 53, a sliding member (sliding portion) 54, a detected member (detected portion) 55, and a roller (roller portion) 56.

[0043] The connecting member 51 is fixed to the conveyor support part 42 that is arranged furthest on the other side Y2 among the plurality of conveyor support parts 42. The connecting member 51 protrudes from the conveyor support part 42 to the other side Y2. Note that the connecting member 51 may be fixed to a member other than the conveyor support part 42 in the reinforcement mechanism 40.

[0044] The connecting member 51 is provided with an upwardly extending erected portion 511. The erected portion 511 is provided with a pair of sensor support portions 512, 512 extending toward the other side Y2. The pair of sensor support portions 512, 512 are disposed opposite to each other in the curvature muscle direction X.

[0045] FIG. 8 is a front view showing the height detection mechanism 50. As shown in FIG. As shown in Fig. 8, the sensor 52 has an upper sensor 521 and a lower sensor 522. The upper sensor 521 is provided on one of the pair of sensor support portions 512, 512. The lower sensor 522 is provided on the other of the pair of sensor support portions 512, 512. The lower sensor 522 is disposed below the upper sensor 521. The upper sensor 521 and the lower sensor 522 are fixed to the reinforcement mechanism 40 via a connecting member 51. The upper sensor 521 and the lower sensor 522 are disposed opposite to each other in the curved reinforcement direction X. The upper sensor 521 and the lower sensor 522 are, for example, metal sensors.

[0046] 7, the support member 53 is fixed to the connecting member 51. The support member 53 is fixed to the reinforcement mechanism 40 via the connecting member 51. The support member 53 is a cylindrical member whose axial direction is the vertical direction. The support member 53 has a through-hole 531 formed therein that penetrates in the vertical direction.

[0047] FIG. 8 is a front view showing the operation of the height detection mechanism 50. As shown in FIG. 8, the sliding member 54 is a columnar member whose axis is in the vertical direction. The vertical middle portion of the sliding member 54 is inserted into the through-hole 531 of the support member 53. The sliding member 54 is formed with a guide hole 541 extending in the vertical direction. The tip of the guide shaft portion 58 fixed to the support member 53 is arranged so as to be guided in the vertical direction in the guide hole 541. This allows the sliding member 54 to slide in the vertical direction inside the through-hole 531 of the support member 53.

[0048] The detected member 55 is a cylindrical member with its axis extending in the vertical direction. A sliding member 54 is inserted into a through-hole inside the detected member 55, and the detected member 55 is fixed to the sliding member 54. The sliding member 54 is disposed above the support member 53. The sliding member 54 is made of a magnetic material. Figure 8(b) shows the steady state, in which the upper sensor 521 and the lower sensor 522 detect the presence (OFF) or absence (ON) of the detected member 55 (from a fail-safe perspective).

[0049] The roller 56 is provided at the lower end of the sliding member 54. The roller 56 is rotatable around the axial direction of the straight line direction Y. By rotating, the roller 56 is able to move on the upper surface of the guide member 30 in the curved line direction X. The sliding member 54, the detected member 55, and the roller 56 are able to move vertically as a unit.

[0050] Next, the operation of the height detection mechanism 50 will be described. As shown in FIG. 6, the device main body 20 itself moves horizontally on the support base 10 along the curved reinforcement direction X. The rollers 56 of the height detection mechanism 50 move along the upper surface of the guide member 30. The sliding member 54 is vertically slidable relative to the support member 53 provided on the reinforcement mechanism 40. As the sliding member 54 moves up and down, the relative vertical positions of the upper sensor 521 and the lower sensor 522 and the detected member 55 change. The upper sensor 521 and the lower sensor 522 detect the detected member 55, thereby detecting the height of the guide member 30. Since the guide member 30 is positioned corresponding to the height of the straight reinforcement B to be placed, the height of the straight reinforcement B to be placed is detected via the height of the guide member 30.

[0051] 8(b), both the upper sensor 521 and the lower sensor 522 detect the detected member 55. In this case, the height detection mechanism 50 transmits a detection signal (no height change signal) that does not change the height of the reinforcement mechanism 40 to a control unit (not shown).

[0052] 8(a), the sliding member 54 is positioned lower relative to the sensor 52 than in the state shown in Fig. 8(b). In this state, the upper sensor 521 does not detect the detected member 55, and only the lower sensor 522 detects the detected member 55. In this case, the height detection mechanism 50 transmits a detection signal (lowering signal) to the control unit to lower the reinforcement mechanism 40.

[0053] 8(c), the sliding member 54 is positioned higher relative to the sensor 52 than in the state shown in Fig. 8(b). In this state, only the upper sensor 521 detects the detected member 55, and the lower sensor 522 does not detect the detected member 55. In this case, the height detection mechanism 50 transmits a detection signal (raising signal) to the control unit to raise the reinforcement mechanism 40.

[0054] FIG. 9 is a perspective view showing the vertical movement mechanism. 9, the vertical movement mechanism 60 moves the reinforcement mechanism 40 in the vertical direction in accordance with the detection result of the height detection mechanism 50. The vertical movement mechanism 60 has a motor 61, a first conveyor 62, a conveyor rotation shaft 63, a first gear 64, a second gear 65, a third gear 66, a fourth gear 67, a second conveyor 68, and a conveyor connecting member 69.

[0055] The control unit receives the detection result of the height detection mechanism 50 as a detection signal and transmits a rotation signal to the motor 61. The motor 61 receives the rotation signal and rotates. The motor 61 is provided with an output shaft 611 that extends in the linear line direction Y.

[0056] The conveyor rotation shaft 63 extends in the line direction Y. The conveyor rotation shaft 63 is provided in the device main body 20. A first gear 64 and a second gear 65 are provided on the conveyor rotation shaft 63. The first gear 64 and the second gear 65 are rotatable together with the conveyor rotation shaft 63 around an axis whose axial direction is the line direction Y. A first conveyor 62 is wound around the output shaft 611 and the first gear 64. The first conveyor 62 is wound in a long loop in the vertical direction.

[0057] The third gear 66 and the fourth gear 67 are provided on the device main body 20 with their axes aligned with the linear line direction Y. The third gear 66 is disposed above the fourth gear 67. The third gear 66 and the fourth gear 67 are disposed on one side X1 of the second gear 65. The second conveyor 68 is wound around the second gear 65, the third gear 66, and the fourth gear 67.

[0058] The conveyor connecting member 69 connects the second conveyor 68 and the conveyor support portion 42 of the reinforcement mechanism 40.

[0059] Next, the operation of the vertical movement mechanism 60 will be described. When the height detection mechanism 50 sends a no-height-change signal to the control unit, the control unit does not send a signal to the vertical movement mechanism 60, or sends a signal not to rotate the motor 61. In this case, the vertical movement mechanism 60 does not operate.

[0060] When the height detection mechanism 50 sends a lowering signal to the control unit, the control unit sends a rotation signal to the motor 61 to rotate the motor 61 in the direction to lower the up-down movement mechanism 60. The output shaft 611 of the motor 61 rotates in direction P1. The first conveyor 62 wound around the output shaft 611 also rotates, causing the conveyor rotation shaft 63 to rotate in direction Q1. As the conveyor rotation shaft 63 rotates in direction Q1, the second conveyor 68 wound around the second gear 65 rotates in direction R1. As a result, the reinforcement mechanism 40 connected to the second conveyor 68 via the conveyor connecting member 69 descends (see the right side of Figure 5). The reinforcement mechanism 40 descends to a height where both the upper sensor 521 and the lower sensor 522 can detect the detection target member 55.

[0061] When the height detection mechanism 50 sends an elevation signal to the control unit, the control unit sends a rotation signal to the motor 61 to rotate the motor 61 in the direction to raise the vertical movement mechanism 60. The output shaft 611 of the motor 61 rotates in direction P2. The first conveyor 62 wound around the output shaft 611 also rotates, causing the conveyor rotation shaft 63 to rotate in direction Q2. As the conveyor rotation shaft 63 rotates in direction Q2, the second conveyor 68 wound around the second gear 65 rotates in direction R2. This causes the reinforcement mechanism 40, which is connected to the second conveyor 68 via the conveyor connecting member 69, to rise (see the center of Figure 5). The reinforcement mechanism 40 rises to a height where both the upper sensor 521 and the lower sensor 522 can detect the detection target member 55.

[0062] Next, the operation of the reinforcement mechanism 40 will be described. When the vertical movement mechanism 60 sets the reinforcement mechanism 40 to a predetermined height, the conveyor 44 rotates so that the side facing the start point 1A of the reinforcement frame 1 descends. When the gripping members 45 grip the straight reinforcing bars B, the straight reinforcing bars B fall between the claws 46, 47 of the gripping members 45 that have reached the lower end or the vicinity of the lower end of the conveyor support 42. The straight reinforcing bars B are placed in the grooves 17a of the straight reinforcing bar receiving member 17. During the stage of placing the straight reinforcing bars B, the rollers 56 are always in contact with the guide members 30, and the reinforcement mechanism 40 is positioned so that both the upper and lower sensors 521 and 522 can detect the detection target member 55. Therefore, the reinforcement is placed at a constant height relative to the straight reinforcing bar receiving member 17. When reinforcement is completed in one groove 17a, the linear reinforcement arrangement device 3 moves to the other side X2 and performs reinforcement in the adjacent groove 17a. The height detection mechanism 50 is activated, and the up / down movement mechanism 60 is activated according to the detection result of the height detection mechanism 50, and the reinforcement arrangement mechanism 40 is activated. This series of operations is repeated.

[0063] The reinforcement mechanism 40 of the curved reinforcement arrangement device 2 operates in the same manner. The curved reinforcement arrangement device 2 does not necessarily have to include the guide member 30, the height detection mechanism 50, and the up-down movement mechanism 60.

[0064] As shown in Figure 6, the position where the reinforcement mechanism 40 places the reinforcement is directly below the conveyor support part 42. The position where the height detection mechanism 50 detects the height of the straight reinforcement B to be placed is the position of the roller 56. There is a length L1 difference between the position directly below the conveyor support part 42 and the position of the roller 56 in the curved reinforcement direction X. For this reason, the guide member 30 is offset by a length L1 in the curved reinforcement direction X with respect to the straight reinforcement receiving member 17.

[0065] In the reinforcement arrangement device 100 configured in this manner, the height detection mechanism 50 detects the height of each of the multiple straight reinforcing bars B to be arranged. The vertical movement mechanism 60 moves the reinforcement arrangement mechanism 40 up and down depending on the detection result of the height detection mechanism 50. The reinforcement arrangement mechanism 40 that has moved up and down arranges the straight reinforcing bars B from a predetermined height. Therefore, multiple straight reinforcing bars B with different reinforcement heights can be arranged from a constant height.

[0066] The height detection mechanism 50 is provided in the reinforcement mechanism 40. Therefore, when the reinforcement mechanism 40 moves to the reinforcement location in the curved reinforcement direction X, the height detection mechanism 50 also moves and detects the reinforcement height, so that the reinforcement height can be detected efficiently.

[0067] Furthermore, the rollers 56 of the height detection mechanism 50 can move along the guide members 30 that are arranged corresponding to the reinforcement height. Therefore, as the reinforcement arrangement mechanism 40 moves to the reinforcement arrangement location, the rollers 56 move along the guide members 30, allowing the height detection mechanism 50 to move smoothly.

[0068] Furthermore, the sensor 52 fixed to the reinforcement mechanism 40 detects the height of the detection target member 55, which is movable together with the roller 56. Therefore, by detecting the height of the detection target member 55 that moves as the reinforcement mechanism 40 moves to the reinforcement placement location, the reinforcement height can be detected.

[0069] Furthermore, the vertical movement mechanism 60 moves the reinforcement mechanism 40 up and down to a height where both the upper sensor 521 and the lower sensor 522 can detect the detected member 55. Therefore, the reinforcement mechanism 40 is moved up and down depending on the relative positions of the upper sensor 521, the lower sensor 522, and the detected member 55 in the vertical direction, and multiple straight reinforcements B with different reinforcement heights can be arranged from a constant height.

[0070] Furthermore, the roller 56 and the detected member 55 are provided on a sliding member 54 that is slidable in the vertical direction relative to the support member 53 fixed to the reinforcement mechanism 40. Therefore, the support member 53 fixed to the reinforcement mechanism 40 can be smoothly moved in the vertical direction relative to the roller 56 and the detected member 55.

[0071] Furthermore, the sliding member 54 is inserted so as to be slidable in the vertical direction through a through-hole 531 formed so as to penetrate the support member 53 in the vertical direction. Therefore, the support member 53 is reliably guided in the vertical direction by the sliding member 54.

[0072] Furthermore, in the past, multiple workers had to coordinate their work on long, heavy rebars on poor footing, resulting in a poor working environment.By using the rebar placement device 100, it is possible to automatically place straight rebars B on the rebar placement frame 1 from the optimal rebar placement height, even when creating rebar units C in which the rebar placement height varies depending on the rebar placement position.

[0073] Furthermore, by using the reinforcement arrangement device 100, it is possible to expect improvements in the above-mentioned work, increased safety, and labor savings, as well as shortening the reinforcement arrangement work time itself.

[0074] In addition, by combining the reinforcement device 100 with a QR code (registered trademark) creation system that reads reinforcement positions, etc., there is the advantage that operation data can be easily set, which can also be used to improve the work efficiency and quality of the entire reinforcement work.

[0075] The shapes and combinations of the components shown in the above-described embodiment are merely examples, and various modifications can be made based on design requirements, etc., within the scope of the present invention.

[0076] For example, in the embodiment described above, the height detection mechanism 50 is provided in the reinforcement mechanism 40, but this is not limiting. The height detection mechanism 50 may be provided in the reinforcement frame 1 and configured to detect the reinforcement height at a predetermined position.

[0077] The reinforcement height adjustment mechanism 4 is also provided with guide members 30 arranged corresponding to the reinforcement height, but is not limited to this. The height detection mechanism 50 may be configured to directly detect the height of the groove 17a of the straight reinforcing bar receiving member 17 to be reinforced.

[0078] Furthermore, the sensor 52 includes the upper sensor 521 and the lower sensor 522, but is not limited to this. The height of the guide member 30 may be detected by a single sensor.

[0079] Furthermore, sliding member 54 is slidable in the vertical direction relative to through-hole 531 formed in support member 53, but is not limited to this. Support member 53 may be provided with a rail for guiding sliding member 54 in the vertical direction, and sliding member 54 may be movable in the vertical direction along the rail.
