考慮して自動化が図られている。The weight of one bar is a long member of 10 kg to 15 kg, and 1 ton as a bundle of piles.
It is generally about 5 tons. Therefore, the work of taking out one bar from the bundle of piles is automated in consideration of its safety.

The stack of piles is divided into two parts by a tapered tapered sorting body, the divided downstream side bar group is dropped onto a waiting stand, and one bar group is dropped by a push-up member from the bar group falling on this waiting stand. It was done automatically by a series of mechanisms that push up the bar, grasp it from both sides and transfer it to the cradle.

る綾掛け棒材が混在している場合がある。By the way, it is desirable that the above-mentioned many bundled rods are linear, but they are not necessarily linear due to manufacturing conditions and so on. There may be mixed traverse rods that are curved and entangled with other rods.

停止する必要があった。[0006] When such traversing rods are mixed in the pile, there is a problem that the sorting member cannot be properly divided into two due to the existence of the entangled rods. That is, in the conventional bar material sorting mechanism, the bar material is divided into two parts only by raising the tapered tapered sorting body, so that the existence of the intertwined traverse bar material group and the weight of the pile of piles As a result, the sorting body is overloaded and cannot enter the pile, and it is necessary to stop the sorting process.

た。In order to solve the above-mentioned problems, the present inventors can reliably and automatically take out one bar even from a pile of bundles in which traverse bars are mixed. As a result of diligent examination of the device, a pair of separating claws with tapered outer sides in the closed position and an opening in which the tips of the pair of separating claws are separated from each other in the transport direction are shown as a sorting body that is particularly easy to stop. By adopting a configuration including an attitude and an opening / closing means for switching between the pair of separating jaws in a closed tapered shape by bringing the pair of separating jaws close to each other, after the pair of separating jaws enter the pile of stacks, the opening / closing means forces the opening / closing means. Since it is opened to the outside, it has been found that even if there is a entangled rod group due to the mixture of traverse rods, it can be easily divided into two.

な形状であってもよい。The pair of separating claws are arranged on the upstream side and the downstream side in the conveying direction of the bar material, and the shape of each separating claw is such that the tips of the separating claws are easily inserted into the stack. It has a tapered shape. Further, in order to open the space between the bar members after the separating claws have entered the pile, it is preferable that at least the outer surface has a taper shape that expands downward. Since the inner surface of the separating claw does not directly contribute to the opening between the rods, there is no particular limitation as long as the shape of the two separating claws does not hinder the function of the other separating claw. The shape may be such that the inner surface becomes a vertical surface.

面く字形に形成されたものが好適である。In addition, not only the outer surface of each of the separating claws is formed in a simple taper shape, but also the height of the outer surface is increased in order to prevent the bar material hitting the outer surface from coming off from the outer surface when opened. It is preferable that the lower side from the middle position in the depth direction has a more gradual inclined surface, and that the central portion is recessed as a whole, for example, one having a V-shaped cross section.

距離が大きく採れる点で有利である。The opening and closing mode of the pair of separating claws is not limited to the type in which both of them move together, but may be a mode in which one separating claw is fixed and only the other separating claw is movable. Further, as a moving mode of the separating claw, either a rotating type or a sliding type may be adopted. Further, even if they are of the same rotation type, either a uniaxial type in which both of the sorting claws are arranged coaxially or a two-axis type in which the respective sorting claws are supported by different shafts may be adopted. In order to lengthen the opening distance of and securely open between the bars,
A biaxial type is preferable, and in particular, if a distance between the two axes is taken and a base end (lower end) of the separating claw is pivotally supported, it is advantageous in that a large opening distance can be taken.

である。The pair of separating claws may be arranged in either a face-to-face arrangement method in which they are located at the same position in the length direction of the bar (direction orthogonal to the conveying direction) or an arrangement method in which they are displaced in the length direction of the bar. However, the arrangement in which the rods are displaced in the longitudinal direction allows the rods to enter from two positions between the rods, which is advantageous for opening the rods. In this arrangement method that is displaced in the length direction, it is preferable that each of the separating claws has a tapered shape, in particular, the inner surface is formed to be a substantially vertical surface in order to make it easy to enter the bar group.

爪同士をシリンダにより連結する態様であってもよい。As the means for opening and closing the separating claw, various modes such as a cylinder system, a rack and pinion system, a screw system can be adopted, but a cylinder system which is capable of instantaneous opening and closing control and has excellent durability is preferable. . In this cylinder method, it is preferable to connect the cylinders to the respective separating claws and drive the opening and closing, but other than this, for example, a mode in which the separating claws are connected by the cylinders may be used.

好適である。The separating claws can be retracted and retracted from the conveying surface by a method in which a sorting body is placed on an elevating table and the elevating table is moved up and down by an elevating means such as a cylinder, or a pair of separating tables. A method of raising and lowering / opening / closing the claw itself by a cam mechanism or the like can be exemplified, but a raising / lowering table method that can take a large raising / lowering stroke and can reliably enter the pile is preferable.

製、非鉄金属等、各種金属類を含むものである。Although the object to be taken out is a rod, the concept of this rod includes a pipe, a wire (including a twisted wire) or a square when viewed from the shape, and a steel when viewed from the material. It includes various metals such as non-ferrous metals.

（又は）端部側に複列に配置した構成が例示できる。The above-mentioned sorting body may be provided at least at one position in the length direction of the bar material, but it is more accurate to adopt a configuration in which it is installed at a plurality of positions in the length direction of the bar material. Sorting can be done. In this preferred embodiment, double-row conveyors for conveying the rods are arranged at intervals in the length direction of the rods, and the sorting bodies are arranged between the conveyors in the length direction of the rods and / or at the ends. An example is a configuration in which two rows are arranged on the section side.

て順次開放する態様等が挙げられる。The opening / closing control of the double-row sorting body can be appropriately selected depending on the target rod material. For example, in the double-row sorting body, there is a mode in which the separating claws are sequentially opened from the central portion to both end sides, or a mode in which the separating claws are sequentially opened from the one end side to the other end side.

し装置に適用するのが好適である。The bar sorting mechanism may be incorporated in any device (system) as long as it divides the pile into two, but it is applied to a device for taking out one bar from the pile of bars. It is suitable. That is, the bar sorting mechanism includes a transport mechanism for transporting a stack of many rods in a direction orthogonal to the length direction of the rod, and a rod group on the downstream side divided by the bar sorting mechanism. It is suitable to be applied to a device for taking out one bar from a pile of piles, which is provided with a take-out mechanism for taking out one bar from the bar.

There is a risk of being connected. Therefore, generally, when the binding weight is about 5 to 10 tons,
It is desirable to divide the stack of rods into small pieces of about 1 to 2 tons before reaching the sorting mechanism.

It is possible to exemplify a mode in which a subdividing member that can freely move in and out is provided on the conveying surface of the bar, and the bar group having a weight that can be sorted is subdivided by the subdividing member.

せき止めるストッパ面とする構成が好適である。The subdividing member is provided with a receiving portion for receiving a required amount of bar group for sorting, and the receiving section is exposed to the conveying surface so that the bar group is lifted and subdivided. The configuration is preferred. In this case, as a mode in which the subdividing member appears and disappears, either an elevating method or a rotating method can be adopted, but since the residual rod material group after subdivision is located on the upstream side of the subdivision member, a fan-shaped subdivision member is used. It is preferable to adopt a method of rotating around the axis, the fan-shaped straight line portion serving as a rod material receiving portion (receiving surface), and the peripheral surface portion serving as a stopper surface for damming the remaining rod material group on the upstream side.

ック台を備えた構成が例示できる。The bar material group after the subdivision is conveyed to the sorting mechanism by the conveyor, but at this time, since the residual bar material group exists on the upstream side of the subdivision member, if the bar material group is also conveyed to the downstream side at the same time, it is subdivided. Parts are overloaded. Therefore, it is desirable that the remaining rod material group be temporarily retracted from the transport surface. As a preferred mode of this, there can be exemplified a configuration in which a stock table is provided on the upstream side of the subdivision member in the carrying direction so as to be able to move up and down with respect to the carrying surface of the carrying conveyor.

り、小分け部材への供給が円滑に行える。This stock table has an upper surface (a surface on which a bar is placed).
Can be a simple flat surface, but it is an inclined surface inclined downward toward the downstream side, and a concave portion for accommodating a bar member is formed by this inclined surface and the subdivision member exposed on the conveying surface. If the subdivision member is exposed from the conveying surface and the stock table is raised to separate the bar material group from the conveying surface, the bar material group is accommodated between the inclined surface of the stock table and the subdivision member. Since a concave portion is formed and the remaining rod material group can be accommodated in this concave portion, the rod material group to be subdivided next is integrated, and the material can be smoothly supplied to the subdivision member.

示できる。On the other hand, the bar group (about 10 to 20 pieces) divided on the downstream side of the sorting mechanism is conveyed to the next take-out mechanism. As this take-out mechanism, the downstream group divided by the bar-sorting mechanism is used. A stand for waiting the side bar group,
A push-up member that pushes up the end portion of one rod member from the rod member group on the standby table from below is provided, and a holding means that holds the rod member pushed up by the push-up member. The structure can be illustrated.

象が綾掛け棒材の場合、収容溝に入ったとしても直に抜
け出す可能性がある。The push-up member has an accommodation groove on its upper surface capable of accommodating only one rod, and one accommodation of the rod can be surely pushed up by this accommodation groove. However, if the object to be pushed up is a traverse rod, there is a possibility that it will immediately come out even if it enters the accommodation groove.

壁面高さが足りず、綾掛け棒材に限らず通常の直線棒材
も含めて、収容溝を乗り越え易いことが判明した。The inventors of the present invention tried to use a V-shaped grooved wheel as the push-up member, and found that the receiving groove and the bar member were in point contact with each other, and the groove height having a V-shaped cross section. Then, it was found that the wall height was insufficient and it was easy to get over the accommodation groove not only for the traverse bar but also for ordinary straight bar.

棒材の離脱が適確に防止できた。Therefore, the accommodating groove is provided with at least a straight line portion which can be brought into line contact with the bar at the start of the push-up, and both walls of the accommodating groove are extended upward at the straight line portion to serve as a retaining wall. By adopting the configuration described above, it was possible to properly prevent the rod material from coming off the accommodation groove.

構成が好適である。The push-up member may be either a linear ascending / descending type or a swiveling / ascending / descending type around an axis. In particular, in the case of the swiveling type, the straight portion and the retaining wall are provided. The adoption of the configuration was effective in preventing the bar material from slipping out. In the case of this rotation method, since the linear portion cannot always maintain the linear contact state with the rod, the linear portion may be configured to obtain the linear contact state with the rod at least when the rod is pushed up. Specifically, it is preferable that the linear portion is formed so as to come into line contact with the bar in a horizontal state in the initial stage of pushing up the bar.

It is subdivided (subdivision process), the subdivided bar group is transported and supplied to the sorting mechanism, where it is sorted into a bar group of an amount that can stand by on the stand of the take-out mechanism (sorting step), and then sorted and transported. Then, one bar may be taken out from each of the plurality of rods carried on the stand (take-out process), and the process may be shifted to the next process.
