Claims (7)

  1. A rebar transport assist device that assists in the transport of rebars processed by a rebar bending machine, A rotatable shaft member extending in the direction of extension of the reinforcing bar, in the state in which the reinforcing bar to be processed is waiting at the reinforcing bar bending machine before bending, A transport assist member that is detachably supported on the shaft member and on which the workpiece reinforcing bar can be placed, The system includes a drive unit for driving the aforementioned shaft member, The drive unit drives the shaft member to position the transport assist member at multiple positions in the vertical direction. The shaft member rotates in the first direction, thereby moving the transport assist member from a high position in the vertical direction to a low position. The rebar transport assist device wherein the transport assist member is supported so as to be immovable with respect to the shaft member when subjected to a load in the first direction, and is supported so as to be movable with respect to the shaft member when subjected to a load in a second direction opposite to the first direction .
  2. A rebar transport assist device that assists in the transport of rebars processed by a rebar bending machine, A rotatable shaft member extending in the direction of extension of the reinforcing bar, in the state in which the reinforcing bar to be processed is waiting at the reinforcing bar bending machine before bending, A transport assist member that is detachably supported on the shaft member and on which the workpiece reinforcing bar can be placed, The system includes a drive unit for driving the aforementioned shaft member, The drive unit drives the shaft member to position the transport assist member at multiple positions in the vertical direction. The transport assist member includes a rod-shaped main body and a curved hook portion provided at one end of the main body. The shaft member includes a locking portion whose outer surface is non-circular in cross-sectional view. The aforementioned conveying assisting member, when mounted on the shaft member, is a rebar conveying assisting device in which the tip of the hook portion of the hook portion abuts against the locking portion and is locked in place by the rotational force due to the weight of the conveying assisting member itself.
  3. A rebar conveying assist device according to claim 2 , The tip of the hook portion of the hook is provided with a hooking portion that curves toward the main body when viewed from the side, The locking portion is composed of a protrusion or groove extending in the axial direction of the shaft member from the outer circumferential surface of the shaft member, in a rebar conveying assist device.
  4. A rebar conveying assist device according to claim 3 , A rebar conveying assist device wherein the distance between the hooking portion and the main body portion facing the hooking portion is set to be greater than the maximum diameter of the shaft member.
  5. A rebar conveying assist device according to claim 2 , A rebar conveying assist device, wherein the other end of the main body is provided with a holding tip that curves in the opposite direction to the direction in which the hook extends.
  6. A rebar conveying assist device according to claim 5 , The retaining tip portion is detachably attached to the main body portion, and is a rebar transport assist device.
  7. A rebar conveying assist device according to claim 5 or 6 , The retaining tip is provided to be movable relative to the main body, in a rebar transport assist device.

Description

This invention relates to a rebar conveying assistance device. Traditionally, reinforcing bars have been bent to achieve a predetermined shape. This bending process utilizes a reinforcing bar bending device (reinforcing bar bending machine) that employs the cooperation of a fulcrum member, a bending roller (force point member) that rotates around the fulcrum member, and a reaction force receiving part (reinforcing bar receiving member) that receives the force on the opposite side of the bending direction during the bending process. Patent Document 1 proposes a device for performing three-dimensional processing of reinforcing bars using bending rollers and pivot members. Japanese Patent Publication No. 2015-116594 This is a schematic perspective view of a rebar processing facility equipped with a rebar conveying assist device, which is one aspect of the present invention.Figure 1 is a schematic side view of the rebar processing equipment as seen from the right side.This is an enlarged side view showing the transport assist member in its engaged state with the shaft member.This is an enlarged side view showing the engagement between the hook portion of a transport assist member and the shaft member, where (a) is an enlarged side view showing the hook portion being attached to the shaft member, and (b) is an enlarged side view showing the state in which the hook portion is attached to the shaft member.This is an exploded perspective view of the transport support component.This is an enlarged cross-sectional view of a shaft member showing a modified example of the shaft member.This is a flowchart showing the method for bending reinforcing bars. Hereinafter, one embodiment representing one aspect of the present invention will be described with reference to the drawings. In the following explanation, the directions of front/back, left/right, and up/down refer to the direction as seen from the front of the rebar processing equipment 100 by a worker. Specifically, facing the rebar processing equipment 100, the front is the near side, the back is the far side, the right is the right, the left is the left, the bottom (the floor surface B where the rebar processing equipment 100 is installed) is the bottom, and the top is the top. The front/back, left/right, and up/down directions are indicated by arrows in the drawings. The up/down direction coincides with the vertical direction. The rebar processing equipment 100 shown in Figures 1 and 2 comprises a frame 20 for supporting each piece of equipment, multiple mounting sections for placing the rebars to be processed 60 (hereinafter simply referred to as "rebars"), a rebar bending machine 40 for bending the rebars 60, a rebar transport assist device 10 having a transport assist member 11 for moving the rebars 60, and a drive unit 15 (motor that rotates the shaft) for driving the transport assist member 11. The rebar mounting sections referred to here include a standby surface 43 on which the rebars 61 (60) before processing are placed, a mounting surface 41 on which the rebars 60 are placed during bending, a removal surface 42 for removing the bent rebars 62 (60), a product mounting surface (not shown) for stocking the processed rebars 62, etc. The rebar bending machine 40 includes, for example, a bending unit 40u positioned at a middle vertical position on the frame 20, positioned on the rebar 60 placed on the mounting surface 41 and defining the bending center of the rebar 60, a bending arm 40b that rotates around the bending support member 40a to apply bending force to the rebar 60, and a front wall portion 40d positioned in front of the mounting surface 41 to hold the front end of the bending support member 40a; and a standby surface 43 positioned on the upper end side of the frame 20 to hold the rebar 60 before bending. At the rear and upper ends of the frame 20, there is a rebar holding section 43a for holding the reinforcing bars 61 before processing, and a transport section 44, composed of a chain or the like, for transporting the reinforcing bars 61 to the rebar holding section 43a. The front end 43t of the rebar holding section 43a protrudes upward, and the reinforcing bars 61 transported from the transport section 44 come into contact with this front end 43t, thus being placed on the rebar holding section 43a. The upper surface of the rebar holding section 43a constitutes the waiting surface 43. The bending unit 40u is installed on a frame table 20a extending horizontally from the frame 20, allowing it to move appropriately in the left-right direction. For example, when processing both ends of a reinforcing bar 60 simultaneously, two bending units 40u are used for simultaneous bending. In this case, as shown in Figure 1, for example, three transport assist members 11 are placed between a pair of bending units 40u arranged at a predetermined interval, and these three transport assist members 11 move the reinforcing bar 60 up and down. It is preferable that the
