Description

[Detailed description of the invention] Jin's release F! 4 is related to the equipment for carrying the equipment from the cooling bed to the next transverse conveyor in the cooling bed facility (for carrying and arranging the equipment from the cooling bed to the next transverse conveyor in the cooling bed equipment prepared for the next stage such as the special nine-bar rolling equipment). The process equipment is targeted here, and this carry-in alignment operation is obtained under various cycle modes by combining the stabilization of the two-piece collector and the forward and reverse conveyance of the seven-way conveyor. The purpose of this is to provide a loading device that can always obtain a proper amount of product, and that can also be housed in a simple and inexpensive device with little trouble. In order to create a cutting force corresponding to the product diameter, the desired number and pitch of the pieces are received, and the run-acting product is placed in one cutting lot. An operating mode that moves up and down between high transferable height positions, and an operating mode that moves up and down between a descending height position below the stacking area of the traversal conveyor and a transportable height position above it. A first collector having an operating mode of descending from a height position to a descending height position as a reference mode that can be selected and combined; There are two collectors on the conveying side of the first collector (a second collector is placed adjacent to the first collector so that it can be raised and lowered and has an operation mode of raising and lowering at the lowering height position and the transfer receiving height position, and the other is a lateral conveyor). is a VCl2 structure that can be freely converted into a flat conveyor and a grooved conveyor, and can freely control conveyance in the forward and reverse directions as a flat conveyor, and is a cycle that selectively combines each standard operation mode of these collectors and the conveyance control of the lateral conveyor. The number and pitch of the cutting rods can be freely controlled depending on the mode to form another cutting rod, depending on the product diameter.

The illustrated embodiment will be described below.

FIG. 1 is a side sectional view of the entire cooling bed facility, and FIG.

Cooling bed 11) It is known that steel bars can be received sequentially through a run-in table (not shown) equipped with a pre-stage button (not shown) and a push-up loading device (not shown). 1a) and movable rake (1b)
The same can be said of arranging an appropriate number of these in the width direction and feeding them at a predetermined pitch.

+31fl) The transfer conveyor lifter is controlled to move up and down with the stroke shown using the swinging fulcrum on the right side (not shown) in Fig. 1, and when the product is received, it is placed on the run shaft table (4) arranged orthogonally at the right end in the drawing. The product is placed on the machine with a downward movement and the next cutting process is carried out.

In this cutting process, as is known, flat blade cutting is performed with a limit of about 20 m diameter, and for larger diameters, so-called hole-shaped blade cutting is performed, and a commonly used shear (not shown) is used. do.

It is well known that when dealing with products having various diameters, it is advantageous to use a cutting force with a number and arrangement pitch of 9, which corresponds to 6 diameters, and this invention also takes into account this point of view. The device introduced here is mainly composed of two levers: a first collector (C1) and a second collector (C2).

Both collectors (CIXC2) are placed close to the rear end of the cooling bed [1], and their appearance is as follows:
5) is a conveyor frame arranged in parallel on the i-column (61...), and each part (both collectors (C1) (C2) ffi) on the side of the cooling bed +1 of the frame fil is arranged in parallel, and these are arranged in parallel on the lower shaft (7 ) and lifting cylinder (pneumatic) (81 (81 and connecting rod (91 (91 etc.)
It takes the form of bowing down centered on.

If these devices are shown as a unit, they are as shown in Figures 2 and 6, and each side of both collectors (Ct) (C2) (the transverse feed conveyor (2) and the sprocket (11) are adjacent to each other). configured.

The shape of the first collector (C1) consists of a lever-shaped part that projects from the horizontal axis fulcrum (lO) toward the cooling bed Tll, a part connected to the curved connecting rond (9) at the lower part of the tip, and a movable part at the upper part of the tip. The receiving surface for transferring the product from the lake (1b) consists of an inclined transfer surface α2, and a second surface α2 for receiving the product.
Collector (C2) Vi, similar (slightly short lever part, connecting part, and upper end L-shaped stationary @ (13), both of which are attached to the side Kfi!i! of the first collector (C1). The second collector (C2) is inserted into the guide 041 so as to be vertically movable.

The above-mentioned jet conveyor (2) is a chain type, and has 28 grooves (a)k on its outer periphery, which will be described later.In some cases, the jet conveyor (2) is configured by disposing these grooves intermittently in several places, and in other cases, it is configured with a flat link type. In some cases, it is left as it is, and in either case, it is a reversible type.

The cycle mode using these two levers is introduced as follows.

Sokuchi, ``hira j, r+11tJ, rllllz-1,
There are r#a-1 modes, which are selected depending on the state of cutting in the cold shear.

In the case of Yazu "flat" mode, it is used when the number of cuts (Nc) with the cold shear exceeds 28, and this is because the product size is 12.7tr as shown in the upper part of Table 1.
Targeting the range of ttl-22rvnyj, the number of trees cut in cold water was 42 to 80, and these were

The cycle mode at the time of import is schematically illustrated in sequence in FIG. 6(I).

Here, the beak feed conveyor (C) is generically called ``flat'' because it is a flat type, and the operation of ■ is carried out by both collectors (C

c2) As a t-stopper, the product (X) is set at a height that can accept the transfer and is placed on standby, and the product (X) transfers from the white circle shown in the figure to the black circle. Next, the first collector (C1) is raised to a height where it can be transferred as shown by ■ and transferred onto the second collector (C2),
Next, as shown by ■<@1 collector (CI) t- lower it again and insert the receiver as shown in the next product (X) t-black circle. It has progressed so far with 4 seconds of bribe, and 700 collectors (CI)

At the same time, the conveyor is driven in forward rotation.

Next, as shown by ■, both collectors (CI) (C2)
``We will accept many books at this time! Because it is necessary to arrange the products in one row, the conveyor (2) is driven completely in reverse, and the two terminal products (X) on the conveyor (2) are placed side by side by the stopper function trap of the second collector (Q).

In this way, one cycle mode is completed by performing the transfer and transfer of ■■. In this case, the reason for the reverse rotation is that, as will be described later, the stationary groove αa... is for 28 wood, and the interval between the two collectors (CI) (C2) is set correspondingly. The fact that a sequence larger than a book cannot be obtained is a button group. These forward and reverse directions are operated by a digital switch.

Here, there is a relationship between the forward rotation amount (&f) and the reverse rotation amount (Sr) 1, assuming that the product diameter is d.

It will be like 2.

Table 1 Collector mode Table 2 Feed amount and return setting in "Flat" mode Therefore, the number of cutting lines is set to 28 or less and 15 or more.In this case, jl(a) is used instead of flat conveyor.
This is carried out using a conveyor with a belt and in the carry-in cycle mode shown in (II) in FIG.

In this case, #i (@)... is for 28 trees, so all you have to do is accept and transfer two pieces at a time, and from the repetition of this process, the conveyor feed, and the sum, the button is placed at a predetermined pitch... Several products (X) are transferred.

In the case of "#I3" mode, there are white circles located nine positions apart from each other by three pitches. ■ is an example of a case where the situation has increased due to the next acceptance situation, and in this case as well, the "distribution" mode is placed at the position indicated by the white circle. In addition, the tank feeding conveyor) and transformer 7 conveyor lifter 1B1K are equipped with a rounding attachment type in which the "flat" and "peng" modes are performed using a common chain.

The present invention is as described above, and therefore, it is directed to equipment in the process of transporting and arranging the cooling bed from the cooling bed onto the next transverse conveyor in cooling bed equipment provided at the next stage such as steel bar rolling equipment. The alignment operation is achieved through the control of the two-piece collector and the forward/reverse conveyance of the cross-feed conveyor (therefore, it can be obtained under various cycle modes, which results in a product cut-off rate of 6.
It is advantageous to be able to provide a carrying device that can be used in a simple and inexpensive manner with few troubles, and which can be used in accordance with the diameter.

Note that the collectors (C1) and (C2) may be of a vertically elevating type other than the lever type.
