BACKGROUND OF THE INVENTION
The present invention relates to a stereoscopic warehouse to verify the material received into the warehouse.
[0002]
[Prior art]
Conventionally, three-dimensional cutting systems measure the width, height, and length of materials at the time of warehousing and manage both input values and measured values as inventory, but in order to prevent input errors and material errors, It is common to check the size together.
[0003]
In other words, a plus or minus error is set as a parameter for the input value, and if it is within the error range, it is stored as a regular material, but the material that is not within the error range matches the input value. Judging that there is no, I can not enter the warehouse.
[0004]
[Problems to be solved by the invention]
However, some materials have a large size error relative to the nominal value of the input material, and with the conventional technology as described above, even regular materials that are within the error cannot be received due to being caught by a check. There is a problem that comes out.

By further moving and detecting the detection light L1 again, the opposite end face (lower end face) is detected, whereby the size in the height direction of the material W is calculated from the distance that the height measuring device 59 has moved up and down. .
[0024]
Similarly, the width measuring device 63 is moved left and right by a width direction moving device (not shown) so that the workpiece W is inserted between the upper and lower members 63U and 63L of the width measuring device 63, and the detection light of the photoelectric sensor 67 is detected. By detecting the end face (right end face) of the material W when L2 is blocked by the material W, and further detecting the end face (left end face) on the opposite side when the detection light L2 is received again after moving. The size of the material W in the width direction is calculated from the distance traveled by the measuring device 63.
[0025]
FIG. 1 shows a configuration of a control device 69 as a material checking device for incoming materials according to the present invention. In this control device 69, an input device 73 such as a keyboard for inputting various data such as parameters to be described later and an output device 75 such as a CRT for displaying various data are connected to a CPU 71 that performs various calculations. . Moreover, the photoelectric sensor 65 of the height measuring device 59 of the material measuring device 40 and the photoelectric sensor 67 of the width measuring device 63 are connected as size measuring means.
[0026]
The CPU 71 is connected to a memory 77 that stores data when parameters are input from the input device 73, and has a height as described above based on signals from the photoelectric sensor 65 and the photoelectric sensor 67. A calculating unit 79 that calculates the height size and width size of the material W from the moving distance of the measuring device 59 and the moving distance of the width measuring device 63, and the material W that is input as the size of the material W calculated by the calculating unit 79 A comparison / determination unit 81 for comparing the size of W as described later is connected.
[0027]
Further, based on the determination described later by the comparison determination unit 81, the temporary interruption command unit 83 for temporarily suspending the warehousing operation, the warehousing cancellation command unit 85 for suspending the warehousing operation, and the operator's judgment of the suspending warehousing operation. Is connected to the forced warehousing command unit 87 that is restarted.
[0028]
The comparison determination unit 81 checks the incoming material using the incoming material check method according to the present invention as described below. That is, D is the nominal size of the material W to be stored, which is input in advance and stored in the memory 77, and X is the size of the material W (for example, the height direction size or the width direction size) calculated by the calculation unit 79. If the material error range, which is an error range defined for the nominal size, is Δ, and the material allowable range to be input as a parameter for each material W is δ,
(1) If it is determined that D−Δ ≦ X ≦ D + Δ is satisfied, it is determined that warehousing is possible and the warehousing operation is continued unconditionally.
[0029]
(2) When it is determined that D−δ ≦ X <D−Δ or D + Δ <X ≦ D + δ is satisfied, the warehousing operation is temporarily interrupted by a command from the temporary interrupt command unit 83, and the operator makes an input error. Check if there is any mistake or material mistake. And when it is neither, an operator pushes a button and restarts warehousing work by the command of the forced warehousing command part 87. On the other hand, if it is determined that there is an input error or material error, the warehousing is stopped.
[0030]
(3) When it is determined that X <D−δ or D + δ <X is satisfied, the warehousing is stopped by a command from the warehousing stop command unit 85.
[0031]
From the above results, it is possible to automatically measure the size of the material W, and when this measured size is compared with the nominal size of the material scheduled to be received, it is determined that the size is the same. Since the goods are received, the management of the materials can be reliably performed.
[0032]
In addition, when entering the size of the material scheduled to be received, in addition to the material error set in advance with respect to the nominal size, an allowable range that can be regarded as the same size is entered as a parameter. Since the operator determines whether or not the material W can be stored, the material W within the allowable range that can be regarded as the same size but not within the material error can be stored and managed.
[0033]
The present invention is not limited to the embodiment of the invention described above, and can be implemented in other modes by making appropriate modifications. That is, in the above-described embodiments of the present invention, the material W has been described as an example of a round cross section such as a round steel or a steel pipe, but can also be applied to various shapes.
[0034]
【The invention's effect】
As described above, the material to be received into solid shelves conveyed by by lever material unloading apparatus of the present invention first measures the size, determined to be within the error range this size to the nominal size of the material If received, it will be received. On the other hand, if it is determined that the measured size is not within the error range but is within the allowable range set as a parameter in addition to this error range, the warehousing operation is temporarily suspended and the operator's judgment is awaited. Since the goods are received only when the worker determines that they should be received, it is possible to receive and manage materials that are not within the material error but within an allowable range that can be regarded as the same size. Further, when it is determined that the measured size is not within the error range or the allowable range, the warehousing operation is stopped, so that an input error or a material error can be prevented.
