Description

[Detailed description of the invention] (Field of industrial application) The invention is a method for counting and sorting steel bars into subgroups in an orderly manner in a steel bar delivery facility before cutting a predetermined number of steel bars by cold shear. Regarding equipment.

(Prior art) Conventionally, with equipment for cutting steel bars with the flat blade of a cold shear, a number of steel bars that match the cutting capacity of the shear are counted on, for example, a rake-type cooling bed, and then sheared as one group by an integrated chain conveyor. It is designed to be transported to the runout roller table opposite. The steel bars on the runout roller table are cut as one group by shearing, so in order to group them into bundles, it is necessary to sort them by number of bundles using a finishing device.
The equipment and labor costs are high. This means that even if we take great pains to count the number of steel bars on the cooling bed, this is not utilized at all as the number of bundled steel bars.

(Problems to be Solved by the Invention) The present invention improves the deficiencies of the conventional equipment, and counts the number of bars and sorts them into sub-groups in an orderly manner during the delivery of the bars from the cooling bed to the runout roller table. Therefore, it is an object of the present invention to provide a device that eliminates the need to count the number of bundles at the time of binding.

(Means, effects, and embodiments for solving the problem) The purpose of the present invention is to transport a predetermined number of steel bars in one group from a rake that serves as a cooling and counting role to an accumulating chain conveyor, and then to a cold shear. In connection with the equipment to be transferred to the runout roller table, an elevating partition plate with a guide plate is installed in the runout roller table, and the chain speed of the integrated chain conveyor is changed to divide the equipment into multiple subgroups. This is achieved by incorporating a steel bar number sorting device that transfers the sorted steel bars as they are to an elevating partition plate while being separated by a guide plate.

Next, the steel bar number sorting device of the present invention will be specifically explained with reference to the attached drawings. FIG. 1 shows a side view of one embodiment.

The device of the invention is integrally integrated in connection with the rake 1 on the right in FIG. 1, the intermediate accumulating chain conveyor 2 and the runout roller table 3 on the left. Since the long steel bar 4 to be cut by cold shear (not shown) moves from the right side to the left side, explanation will be given in accordance with that order.

The rake 1 is constructed by arranging a fixed rake 6 and a movable rake 7, each of which has a receiving groove 5 arranged on its upper side for supporting a long steel bar, and a movable rake 7 arranged horizontally and parallelly at intervals suitable for supporting a long steel bar. In contrast to the fixed rake 6 fixedly installed by 8, the movable rake 7 is connected to the eccentric drive device 10 via the support beam 9, and is driven by the eccentric drive device 10 to move circularly in a parallel plane and move up and down.
During operation, the steel bar is transferred to the left one groove at a time. During this time, the number of steel bars in one group is counted, and the hot steel bars are cooled. Since Rake 1 is also a cooling bed, it can be replaced by other similar types of cooling beds that can count steel bars.

The counted number of steel bars in one group are aligned at the left end of the rake 1 in the runout direction, which will be described later, by the bar end aligning device 11.

In the accumulating chain conveyor 2, a chain 14 is stretched across a drive device 12 and a group of 13 sprockets, and the horizontal upper chain table continues to the left end of the rake 1, so that the steel bars are transferred from the rake 1 to the chain of the accumulating chain conveyor. transported onto the table.

In this bar delivery process, by changing the operating speed of the chain 14 according to the plan, one group of bar steel is divided into two subgroups A and B with an intergroup interval d, as illustrated in FIG. are arranged. In other words, the subgrouping is such that when each steel bar of subgroup A and subgroup B is delivered from rake 1 to accumulating chain conveyor 2, the speed of accumulating chain conveyor 2 is equal to rake 1.
subgroup A by momentarily increasing the speed of the accumulating chain conveyor 2 between the delivery of the last bar of subgroup A and the first bar of subgroup B. The group of steel bars rapidly moves to the left, and a group interval d is opened between the group of steel bars of subgroup B that is subsequently delivered. The number of subgroups can be greater than two, and the number of steel bars in each subgroup can be arbitrarily selected. Steel bars will not fall on a chain table supported by horizontal guides.

The runout roller table 3 located on the left side of the accumulating chain conveyor 2 consists of conveyance rollers 15 arranged in a row in the direction perpendicular to the plane of the paper in FIG. It is now being moved out.

In the elevating partition plate 17 having the guide plate 16 according to the present invention, the horizontal steel bar receiving plate part 18 rises and lifts the steel bars sorted into subgroups A and B onto the accumulating chain conveyor 2 in the sorted state, At this time, the guide plate 16 intervenes between the subgroups, moves to the left, intervenes between the rowing rollers 15 of the runout roller table 3, and descends to transfer the steel bars to the rowing rollers 15.

That is, when the elevating partition plate 7 to which the guide plate 16 is fixedly attached rises at the accumulating chain conveyor, the guide plate 16 is located at the front-rear interval of the conveyance roller 15 and the longitudinal interval of the accumulating chain conveyor 2. A,
If the bar receiving plate 18 of the lifting partition plate 17 stops at a level slightly lower than the upper circumferential level of the carrying roller 15 when intervening between B and moving to the left and descending at the carrying roller, the bar will not move above the carrying roller. , and the guide plate 16 continues to intervene between the subgroups A and B. Therefore, when the steel bars of subgroups A and B are transported to the cold shear by the transport rollers, disturbance of the steel bars of subgroups A and B is restricted.

Although various known mechanisms can be arbitrarily adopted as the drive device, the one illustrated in FIG.
This is a type of traverser 20 that moves across the platform 19.
1 and the other end is connected by a rod 22, and a drive rod (not shown) is connected to a driven pin 25 on a drive arm 24 attached to a lever shaft 23 to move the traverser 20 up and down. 26 is connected to a refracting arm 27 which is pivotally supported by a refracting arm 2
A drive rod (not shown) is connected to the driven pin 28 on the drive rod 7 to allow the drive rod to move horizontally.

Figures 3, 4 and 5 show other embodiments. In this embodiment, an elevating partition plate 31 having a guide plate 30 is arranged between the rows of rollers 32 on the runout roller table, and is driven by an air cylinder 33 via a rod, lever, and link mechanism 34 to raise and lower the roller level. Go up and down. In this embodiment, the integrated chain conveyor that supports the steel bars 4 sorted into subgroups A and B moves back and forth between the interval D between the elevating partition plates 31 to deliver the steel bars. In this embodiment, the elevating partition plate 31
can be replaced depending on the number of subgroups. In addition, this embodiment is equipped with a pusher 35, and the crop on the front side of the cold shear is moved sideways by lowering the partition plate.

Since the device of the present invention operates in conjunction with the rake 1, the integrated chain conveyor 2, and the runout roller table 3, it is configured as an inseparable device from these, but the operating mechanism thereof is irrelevant to the gist of the invention.

As described above, according to the present invention, the steel bars that have been sorted into subgroups AB on the accumulating chain conveyor are conveyed onto the runout roller table in a state where they are divided into subgroups. Then, the materials are sorted into subgroups by an elevating partition plate provided between the runout roller tables, and then delivered to the cold shear.

(Effects of the invention) As described above, according to the invention, the number of steel bars to be cut by cold shear is divided into subgroups, so the number of groups and bars are controlled by the cooling bed both after shear cutting and in the refining equipment. Since the number of strands is counted, there is no need to count the number of strands when tying. In other words, the number of bundles can be managed for each group and each subgroup.
