Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for processing long objects, and is suitable for processing a wide variety of products in small quantities.゛We carry out various types of processing on long objects, such as metal materials such as medium and long steel, or non-metallic materials such as wood, wood, and construction materials, and the number of long objects to be processed is small. Traditionally, manual methods have been used to process small quantities of raw baby lids of various types.

In the manual method, the shape of the long material is marked in advance (referred to as marking) according to the shape of the long material, and then the gas cutter is used to cut the material and make holes. This method has the disadvantage that it is difficult to maintain constant quality because it requires a large amount of manpower and the skill level of the workers varies.

Therefore, it has been proposed to use numerically controlled gas cutting machines to overcome these drawbacks, but it has been proposed that the workpieces are long and -
For example, a bar for fortune-telling has a length of 1@IIk, so the structure is large and the equipment cost is high, while the length of the bar is 1,000 degrees.

There are problems caused by gas misfires, constant control of the flame, and heat.

, , In addition, to solve this problem, a dedicated rounding machine can be installed along the conveyor and automated. 4. The wooden one shown in Figure 4 is a plan view of a long object machining twin that performs two types of machining. Receiving conveyor 1 for workpieces 2 in the front and back
A delivery conveyor 4 is provided, and a delivery conveyor 4 is provided.
A receiving conveyor 5 of a cutting machine 6 for the second processing step is located in front of the cutting machine 6, and a discharging conveyor 7 is provided behind the cutting machine 6. In order to process a workpiece 2 with a length Lm in a processing line with electricity distributed as shown in FIG. , if the length of each processing machine 3.6 in the line direction is m, the total line length is approximately 4L+2tma.

In addition, in the case of n steps, the total line length is very long, n(2L+4), and requires a huge space for electrical installation, which is an obstacle to practical application.

The present invention aims to eliminate such conventional drawbacks and provide a method for processing long objects that can efficiently process a wide variety of small quantities of long objects without requiring a huge amount of electrical installation space. The configuration of the present invention that achieves this object is such that, when processing a long object, a plurality of processing devices, each of which is movable independently along a conveyor that conveys the long object, is used to process the long object. It is characterized in that the processing device is moved to a predetermined position as soon as the long object is transported by a conveyor, and the required processing is performed on the long object.

A large number of nine rollers 44 are provided so as to be rotatable through the rollers. Then, #i is transported to the processing position of the ml process and the building 2 process.
A clamp device 44 is installed to position and fix 0. This clamping device 44 is provided with supports 45 that sandwich the conveyor in the direction perpendicular to the conveyance of the conveyor frame 42, and each of the boats 45 has a long object 20 at its tip.
The base end of the position correcting electric cylinder 470, which is equipped with a stopper 46 for positioning by abutting against the cylinder, is oddly mounted. Therefore, the elongated object 20- can be positioned and fixed at a predetermined position by adjusting and controlling the amount of expansion and contraction of the opposing position correction electric cylinders 47.

Next, as shown in FIG. 3, the one-hole punching machine 60 attaches wheels 61 to two running rails 80 installed on the floor ImK below the conveyor frame 42 along the conveyance direction of the processing line conveyor 40, and A trolley 6s equipped with a guide roller 6z that rotates along the INK is energized, is mounted on the trolley 63 and is movable in the transport direction, and is equipped with a traveling drive device and a position control device (not shown). Self-propelled and positioned. To attach the drilling machine 60 to the trolley 6s, a drilling machine body 64 is placed on the trolley 63, a vikes is attached to a part of the tip of the drilling machine 64, and nine tool supports 4! I66 is made slidable in the width direction and up and down direction of the long object 20 by a lateral drive cylinder 67 and a traveling girder 68, and has the same structure as a general drilling machine.

★Ta. As shown in FIG. 4, the cutting machine 70 is of a sawtooth type and is attached to a cart 71 via a turning device so that the long object 20 can be cut not only at right angles to the axial direction but also at a predetermined angle. It has the same structure as that of the bogie 71 drilling machine 60, and is equipped with wheels 72 and guide roller roughs 3, and is also equipped with a traveling drive unit and a position control device (not shown), and is capable of self-propulsion and positioning. . A shaft 74 is mounted on the cart 71, fixed to the bottom of the cutting machine main body 75, and attached so that the cutting machine main body 75 can turn together with the nine gears 76. gear 7

Next, the operation of such a long object processing line and the method for processing a long object of the present invention will be explained based on process diagrams shown in FIGS.

First, as shown in FIG. 5-), the long object 20 is carried onto the receiving conveyor 30 by an overhead crane or an upstream conveyor. 6), the receiving conveyor, the conveyor 30, and the processing line conveyor 40 are driven, and the long object 20 is placed on the processing line conveyor 40 by half 14 of the length L of the long object 20. Move and stop the respective conveyors 30° and 40. Then, when the long object 20 is positioned using the stopper 46 at the tin tip of the position correction electric cylinder 47, -
and secure it in place. On the other hand, when the trolley 63 on which the drilling machine 60 is mounted is moved so that the center of the drill 65 is at a predetermined hole drilling position, the traveling girder 68 is moved in a negative direction, and the driving girder 68 is moved to Perform hole drilling.

Next, in order to perform the second process, the first processing line conveyor 40 is driven again as shown in FIGS. Position the entire object 2o.

In this case, the conveyance timing of the long object 20 is the one-item processing of the long object (not shown) K flowing forward in the conveyance direction, that is, the time when the cutting is completed and the long object 20 is processed in one strip. This is possible only after the machining, or drilling, is complete.

As shown in the same figure &), half of the rear end of a long object 2° is applied to the half of the tip described above. Hole drilling is performed by controlling the positions of the conveyor 40 and the hole puncher 41I60. In the case of this embodiment, since the drilling position is different between the front half and the rear half of the long object 20, the positioning is controlled each time. On the other hand, in order to cut half of the tip of the long object 2G, the long object 2G is transported to a predetermined position by the processing line conveyor 40, and the stopper 46 at the tip of the position correction electric cylinder 47 is used to cut the long object 2G.
In addition to positioning and fixing in the 00 width direction, the cart 71 on which the cutting machine 70 is mounted is moved to position the saw 79 at the cutting position. After positioning in this manner, cutting is performed.

Incidentally, if the cutting surface is not perpendicular to the axial direction of the long object 20, the cutter 70 can be rotated by a predetermined angle using the rotating housing to perform the cutting.

In this way, the first and second steps for the front half of the long object 20 are completed, and #! for the rear half is completed. After the first process is completed, the second half is cut in the SS process.
The elongated object 20 is conveyed again by h as shown in FIG.

Thereafter, as shown in FIG. 4(f)K, a cutting machine 70 is mounted, and a nine-carriage 71 is positioned at a cutting position for the rear half of the long object 2o to perform cutting.

Thus, Nabete no Kou II! When the process is completed, one long object 2o is conveyed by a distance b and moved to the delivery conveyor S as shown in the same figure.
Transfer OK and transport using overhead crane or downstream conveyor.

In the above explanation, we will explain the case of machining one long object. In this way, in the method of the present invention, the total length of the machining twin is 3L for the length LK of the long object 2o, and compared to the conventional 2-work SO machining line total length (4L + 24)K, it is (4L + 24)K. !, +!j)-1L
= (L + 2t) minutes can be wrapped up in I[, improving space efficiency.

First, even when the processing machine 11 has two or more processes, the width of each processing machine, that is, the length t in the line direction is long oH@x, and the number of processes n is very short by 1 (long length equal to 1). ((n
・)K, it is possible to carry out n processes by transporting long objects and moving each processing machine while keeping the total length of the machining line 3L, which reduces the machining line length n (2
L+t ), n(2L+1)-31,z(2n-
3) The line length can be shortened by L+nj, and the shortening of the conveying distance also reduces the conveying power, resulting in energy savings (4).

First, the processing machine can be hooked through a rotating device, so the range of processing can be expanded, and diagonal cutting as in Example IIIA is also easy, making it suitable for high-mix, low-volume production.

9. In the above embodiment, the case where processing and conveyance are performed by repeatedly operating the conveyance line and stopping 6 times has been explained. If the conveyance line speed and the running speed of the processing machine are synchronized and the relative speed is set to zero, the conventional 1. It is possible to perform processing even during transportation, which is the processing down time, and it is possible to shorten non-processing time and increase processing efficiency. In addition, as a processing machine, there is a drilling machine,
It goes without saying that not only a cutting machine but various other machines can be used.

As described above in detail in the embodiments, according to ***, long objects can be processed in one short processing line, and the processing efficiency is also high.
