Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a vertical reinforcement feeding device for a wire mesh manufacturing machine.

<Prior art> In order to send the parallel vertical bars to a wire mesh welding machine and weld the horizontal bars one after another, the wire mesh manufacturing machine is equipped with a vertical bar array delivery mechanism, and an inclined guide surface is connected to the delivery mechanism from a high place on the side. A device is provided for rolling down the longitudinal reinforcing steel bars one by one along the line and sequentially attaching them to each arrangement position.

The vertical bars of the delivery mechanism are arranged at minimum intervals according to the general welded wire mesh standard, and any one of them is selected as the vertical strip position of the wire mesh to be made. Therefore, it is surprisingly difficult to mechanically drop the vertical reinforcement steel rods one after another into the required array positions, rather than obtaining them to be rolled down from the side of the delivery mechanism.

An example of a conventional vertical reinforcement (steel rod) supply device is shown in FIG. Steel rod A for longitudinal reinforcement is installed on inclined guide surface 1 from a high place on the side.
If it rolls down and falls into the required receiving groove 2a of the comb-toothed groove plate 2 which is placed on top of the vertical strip arrangement delivery mechanism (not shown), the desired vertical strip arrangement position will be reached.

In this example, the upper end is supported by a horizontal shaft 3 and the lower end is engaged with a bearing shaft 6 on a horizontal sliding member 5 with vertical guide grooves 4 between the lower end of the inclined guide surface 1 and the comb-tooth groove plate 2. A telescopic rod 7 and a guide plate 8 along the rod are provided.
A drive mechanism (not shown) moves the horizontal sliding member 5 to the left and right in the figure as shown by the chain line, and the vertical guide groove 4
By moving it onto the required receiving groove 2a,
The steel rod A is caused to fall along the guide plate 8 and drop into the receiving groove 2a. A vertical restraining member 9 is erected on the horizontal sliding member 5 to prevent the steel rod A from jumping out to the left in the figure.

<Problems to be solved by the invention> This type of vertical reinforcement supply device is not limited to the example shown in FIG. 5, but has become large-scale. This idea attempts to simplify that.

<Means for solving the problem> The vertical reinforcement feeding device of the wire mesh manufacturing machine of this invention has an inclined guide from a high place on the side of the vertical reinforcement arrangement sending mechanism that feeds the parallel vertical reinforcements to the wire mesh welding machine. In a vertical reinforcement feeding device of a wire mesh manufacturing machine, in which vertical reinforcement steel bars are rolled down one by one along a surface and sequentially placed at each arrangement position, steel rods that stand at several locations on the above-mentioned delivery mechanism and fall from the above-mentioned guide surface. Several grooved plates have slanted upper edges that support the steel rods without deflection and allow them to continue to move under their own weight, and have steel rod receiving grooves cut in a comb shape from the upper edges to the above-mentioned longitudinal bar arrangement positions. Each common operating rod passes through the lower edge of the upper edge of each corresponding receiving groove of each groove plate, and the operating rod is located near the upper edge of each receiving groove of each groove plate and is driven by the operating rod to move the upper edge of the groove plate. It is characterized by comprising an opening/closing member that can be switched between a posture for picking up and dropping the steel rod into the receiving groove and a posture for allowing it to pass through.

<Function> The conventional vertical reinforcement supply device has the slope guide surface 1 shown in Fig. 5.
Intermediate guide members 7 and 8 are provided between the lower end and the upper surface of the comb-tooth groove plate 2, and by changing the inclination angle of the guide members, that is, by changing the path through which the steel rod falls, the steel rod A
were placed in the required locations.

On the other hand, this idea changed the idea and completely abolished the intermediate guide material. Then, the upper edge of the comb-shaped groove plate 2 is smoothed and inclined, and an opening/closing member is added to each receiving groove 2a. When the opening/closing member is closed, the steel rod A becomes the groove plate 2.
The idea is that the upper edge is turned and the opening/closing member falls into the open receiving groove.

In other words, the grooved plates of this invention stand in several places on the vertical bar array delivery mechanism and have steel rod receiving grooves, which is the same as before, but the upper edge of each plate is sloped, making it difficult for the plates to fall off. The steel rod is directly supported without any intermediate guide material and continues to be moved. In order to make the steel rod advance, an opening/closing member is attached to the entrance of each receiving groove on the groove plate, and whether the steel rod is picked up and dropped into the groove or transferred and passed through is determined by operating the common operating rod of each receiving groove opening/closing member.

First, all the opening/closing members are closed, and the necessary ones are sequentially operated among the common operation rods located at each vertical reinforcement arrangement position, and the steel rods are dropped one after another into the required arrangement via the receiving groove. .

<Embodiment> FIG. 1 is an elevational view of an embodiment of this invention, viewed in the same direction as FIG. 5 of the conventional example. FIG. 2 is a partial plan view seen from above in FIG. 1, and FIG. 3 is a plan view of the delivery end side of the longitudinal strip arrangement delivery mechanism 10.

11 in FIG. 1 is a conventional inclined guide surface for supplying steel rods, similar to 1 in FIG. 5, and the mechanism for dropping the steel rods A one by one is omitted. Reference numeral 12 denotes groove plates unique to this invention, which are provided at intervals in the vertical direction on the vertical strip delivery mechanism 10, as shown in FIG. The number of grooved plates 12 is such that the distance between them is such that the steel rod A can be placed thereon without bending, and only two of them are shown in FIG.

The longitudinal stripe arrangement positions P of the longitudinal stripe arrangement delivery mechanism 10 in FIG. 3 are six locations indicated by chain lines, and a delivery grooved roller 13 is lined up at each location. A receiving groove 12a of each groove plate is cut vertically at a position where the steel rod A is dropped into each arrangement position P.

The upper edge of the groove plate 12 of this invention is different from that of the groove plate 2 shown in FIG. 5, in order to transfer the steel rod A, it is generally smooth, and only the upper end of the receiving groove 12a and the inclined part for introducing the steel rod at the entrance thereof are smooth. Concave.

The intermediate receiving groove 12a is rotated until the steel rod A traveling through the upper edge of each groove plate 12 reaches the intended receiving groove 12a.
It must be transferred over a. Therefore, an opening/closing member 14 is attached to each receiving groove 12a of each groove plate 12. One end of each rod is attached near each receiving groove 12a of the common operating rod 15 that passes through the lower side of the upper edge of each receiving groove 12a, and when it rotates and stands up, it prevents the steel rod A from moving and receives it. When the steel rod A is in the position of being dropped into the groove 12a and lying along the upper edge of the groove plate 12, the steel rod A is in the position of continuing to move without any hindrance.
The opening/closing member 1 is located only near the receiving groove 12a at the left end in FIG.
4 is missing because there is no need for the steel rod A to pass over this groove. However, in order to simply block the steel rod A and ensure that it falls into the groove, an opening/closing member 14 may be provided in the same manner as in other grooves.

Each of the five operating rods 15 is equipped with the same number of opening/closing members 14 as the groove plates 12, and they simultaneously switch the opening/closing operation, that is, the steel rod dropping or passing posture. As shown in the figure.

This FIG. 4 is an elevational view of the end plate 16 (not shown) of the vertical strip arrangement delivery mechanism 10 of FIG.
A book operating rod 15 is pivotally supported by an end plate 16 and has a gear 17 attached to its tip. By turning this gear 17, the opening/closing member 14 is placed in an upright position or a down position. This is done by moving the rack 18 that meshes with the gear 17 in and out by a fixed stroke using a hydraulic cylinder 19. Initially, each cylinder 19 sets all the operating rods 15 to the closed position, drops the steel rods A into the farthest (lowest) groove 12a, and then sequentially sets the operating shaft 15 to the open position to move the steel rods A one after another to the arrangement position. It can be automatically controlled to drop.

Although one embodiment has been described above, this invention can be varied and applied in various ways depending on the well-known technology of the designer in charge, even within the scope of the gist of the invention. , common operating rods, and their support mechanisms should be able to perform the same function with different designs by machine designers.

<Effects of the invention> This invention was developed by placing the movable intermediate guide member, which was conventionally considered indispensable in the vertical reinforcement supply device for welded wire mesh, in other words, the steel rods for the longitudinal reinforcement, which roll down one by one, on a guide member with a variable inclination angle. Great simplification has been achieved by completely eliminating the falling path moving means that successively moves the lower end of the material onto the receiving groove above the intended arrangement position.

Conventionally, the groove plate stood on top of the longitudinal reinforcement arrangement delivery mechanism and was merely a guide for receiving steel rods to each arrangement position, but this design has an inclined upper edge that allows the steel rods to move under their own weight, and each receiving groove Since it has an opening/closing member, and a common operating rod is added to open/close the opening/closing members at each arrangement position at the same time, the falling steel rod can be directly connected to each groove plate without the need for a conventional intermediate guide. It became possible to receive them on one side of the upper edge and drop them in any desired arrangement position while transferring them to the other side.
