Abstract

PURPOSE:To automate the sorting into a product and waste in order to improve productivity by adding to NC data to identify whether a part worked by a working machine is a part corresponding to the product or a part corresponding to the waste. CONSTITUTION:Identifying data to judge whether the worked material is the product or the waste is transferred to an NC controller 63. A working data signal is judged by an external controller 3. When the worked part is judged by the external controller 3 to be a product, a separation preparation signal is issued. The product is slid on a shooter 68, a product receiving part 5 by the control of the NC controller 63 which has received this signal and dropped on a conveyor 6. It is transmitted by a belt 13 and stored in a product storage box 9. On the contrary, when a data signal after laser beam machining judges that it means waste, a large clearance is formed between the tip 68a of the shooter 68 and the top 5b of a product receiving part 5 and the waste is dropped directly into a waste storage box 7.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for sorting products processed by a processing machine and waste materials.

<Prior Art> As a general-purpose processing method for sheet metal products, a laser press machine is known which combines fusing processing using a laser beam and punching processing using a punch.

FIG. 5 shows an example of a conventional laser press machine.

In the figure, this laser press! ! ! 461 is a laser press main body 62, an NC control section 63, an operation console 64 for instructing laser press operations, a conveyor 65. storage box 6
It consists of 6 etc.

Furthermore, a laser press rod 67, a shooter 68, and the like are attached to the laser press main body 62. Among these, the laser press rod 67 is provided with a plurality of work clamps 69.
9 makes it possible to clamp the ends of the workpiece 71 as shown in FIG. Further, this laser brace rod 67 is moved in the X-Y direction while clamping the workpiece f471, and during this movement, the workpiece 71 can be sequentially punched and cut by laser beam. And this laser
The operations of the press rod 67 and the work clamp 69 are performed by commands from the NC control section 63, which are executed based on numerical control data input in advance, so-called NC data.

Further, the chute 68 is normally kept in a horizontal state without being tilted, but when processing processed products and waste materials, the chute 68 is tilted so that its lower end extends above the conveyor 65. It has become. Note that a magnetic sensor 70 is provided on the shooter 68.

In the laser press machine 61 configured in this way,
When the workpiece 71 is clamped by the work clamp 69 and further moved in the X-Y direction together with the laser brace 67, during this movement process N Cft5l 04 part 6
Punching and fusing processing are sequentially performed on the workpiece 71 according to instructions based on the NC data of No. 3.

FIG. 6 shows an example of this processing, in which the processed material 71
The case where a product 72 is processed from is taken as an example. In addition,
Of the processed material 71, portions 73, 74, and 75 indicate parts to be removed from the product 72, that is, parts that will become waste materials. In this processing, when processing the product 72 from the workpiece f171, the NC control unit 6
Controlled by 3. In addition, when processing the first waste material 73, the laser press rod should be moved so that the point marked with the symbol ■ in FIG. 67 moves 0 Next, the laser beam advances the laser cut from point I in the direction of the arrow in the figure, and when it returns to point ■, the waste material 73 is processed. Further, when the processing of this waste material 73 is completed, the laser press rod 67 is moved to a position corresponding to the magnetic sensor 70. When the waste material 73 moves to a position corresponding to the magnetic sensor 70, the chute 68, which had been held in a flat state until then, is tilted by a command from the NC control section 63. Then, the waste material 73 placed on the chute 68 slides on the chute 68 and is lowered onto the conveyor 65 by FI, and is conveyed by the conveyor 65 to the storage box 66 and stored in the storage box 66. On the other hand, Shooter 68
When the waste material 73 slides on top and falls onto the conveyor 65,
Passage of the waste material 73 is detected by a magnetic sensor 70 on the chute 68 . Furthermore, when this is input to the NC control unit 63, the chute 68 rises again and no longer tilts.
Continue with next program. Then, the waste material 74 to be processed next is laser-processed sequentially starting from the point marked ■ in FIG. , and are stored in the same storage box 66 in the same manner as the waste materials 73.

<Problem to be solved by the invention> As mentioned above, in the conventional processing machine, the processed product 72
and waste materials 7B and 74.75 are stored and processed in the same storage box 66. Therefore, the products 72 and waste materials 73, 74, and 75 stored in the storage box 66 must be sorted by an operator or the like after being processed. This is especially true when a variety of products and waste materials are mixed together, such as when processing multiple products with different shapes from one sheet of processed material F171, and the time required for sorting is proportional to this. There was a problem that it took a while.

The present invention was made in view of the above problems, and its purpose is to improve productivity by automating the sorting of products and waste materials after processing. The sorting consists in providing equipment.

Means for Solving the Problems> In order to achieve the above object, the processing machine according to the present invention separates products from waste materials by using a device that separates the parts processed by the processing machine into products or waste materials. In addition to adding data to the NC data to identify which part is the part to be processed, the sorting method of switching the discharge route after passing through the chute and sorting into the product and the waste material is determined according to the means and processing. The apparatus is provided with external control means for inputting the identification data and controlling the operation of the sorting means in accordance with the identification data.

<Operation> According to this configuration, processing is performed based on NC data, and identification data indicating whether the processed part is a product or waste material is sequentially input to the external control means, and processing is performed based on this identification data. By changing the operation of the sorting means, it is possible to discharge the product or waste material in the appropriate direction. This makes it possible to automate the sorting of processed products and waste materials.

<Example> Hereinafter, an example of the present invention will be described in detail using the drawings.

In addition, in this embodiment, in the case where the waste materials 73, 74, 75 are removed from the processing material 71 and the product 72 is produced, which is the same as that processed by the conventional laser press machine 61 shown in FIGS. 5 and 6. is taken as an example. Note that these waste materials 73, 74, and 75 do not include the original material portions from which the products and scraps were removed.

The laser press machine 1 of this embodiment shown in FIG. 1 and the conventional laser press machine 6 shown in FIGS. 5 and 6
1 is largely different from the conventional laser press machine 61 in that a sorting mechanism 2 is provided in the laser press machine 1 of this embodiment in place of the conveyor 65 of the conventional laser press machine 61, and The laser press machine 1 of this embodiment is provided with an external control section 3, which was not present in the previous embodiment.

Further, the sorting apparatus according to the present invention as explained in this embodiment includes a sorting mechanism 2, an external control section 3, and an NC control section 63.
and a shooter 68. this house,
The sorting mechanism 2 is arranged corresponding to the shooter 68, as the detailed structure is shown in FIGS. 2(a) and 2(b). It is composed of a product receiving section 5, a conveyor 6, a waste material storage box 7, a rotating cylinder 8, and a product storage box 9 disposed adjacent to the base 4.

More specifically, the base 4 is placed on the floor by adjusting feet 10 provided at the four corners of the lower surface of the base 4. Furthermore, by rotating each adjust foot 10 itself, the amount of protrusion from the base 4 can be changed, and by adjusting the amount of protrusion, the inclination and height of the base 4 can be adjusted. It looks like this. In addition, in the figure, only two of the adjusting feet 10 on the near side are visible, and the remaining two are visible.
One is hidden by base 4.

The conveyor 6 is attached to the base 4 via four legs 11, and is provided with an endless belt 13 that is rotated in the direction of arrow E in the figure by a drive means (not shown).

The waste material storage box 7 stores waste materials 73, 7 that slide through the chute 68 when the chute 68 is tilted downward.
Shooter 6 so that Uke can stop 4.75
It is disposed on the base 4 via the pedestal 14 in a state corresponding to the tip 68a of the 8.

The product receiving section 5 is mounted between the waste material storage box 7 and the conveyor 6 via a pair of left and right support legs 15 so as to be rotatable back and forth in the direction of arrow A-a in FIG.

The rotating cylinder 8, together with the product receiving part 5, has a sorting means 16.
It is attached to a position on the pedestal 14 below the product receiving part 5 and closer to the conveyor 6 side than the position where the support leg 15 is attached. The rotating cylinder 8 is made up of a cylinder part 8a fixed on the pedestal 14 and a piston part 8b protruding from the cylinder part 8a. connected. The reciprocating rotation of the product receiving section 5 is controlled by the advance/retreat ratio of the piston 8b, and the piston section 8b is normally pulled and turned on. That is, when the swing cylinder 8 is in the ON state and the piston part 8b is drawn into the cylinder part a, the lower end 5a side of the product receiving part 5 is pulled by the piston part 8b, and the product receiving part 5 The whole is rotated in the direction of arrow A in FIG. 2(a). Furthermore, if the chute 68 is tilted as shown by the dashed line in the same figure at this time, the upper end 5b of the product receiving portion 5 and the tip 68a of the chute 68 will be separated by a large distance. In addition, in this state, if there is a piece of waste material 73, 74, 75, etc. that slides down from the chute 68, it should be removed from the tip 68 of the chute 68 through the path shown by the black line arrow G in the figure.
The waste material falls into the waste material storage box 7 through the gap between the product receiving portion 5a and the upper end 5b of the product receiving portion 5, and is not guided to the conveyor 6 side.

On the other hand, when the swing cylinder 8 is in the off state,
When the piston part 8b protrudes from the cylinder part 8a, the lower end 5a side of the product receiving part 5 is pushed by the piston part 8b, and the entire product receiving part 5 moves in the direction of the arrow a in FIG. 2(b). be rotated. Furthermore, if the chute 68 is tilted as shown by the dashed line in the same figure at this time, the product receiving portion 5
There is almost no gap between the upper end 5b and the tip 68a of the chute 68, and the product receiving portion 5 and the chute 68 are in a substantially continuous state. In addition, if there is a product 72 or the like that slides down from the chute 68 in this state,
It passes along the path indicated by the black line arrow F in the figure, and does not fall to the waste material storage box 7 side, but is transmitted onto the product receiving section 5 and falls onto the conveyor 6. Furthermore, when the belt 13 of the conveyor 6 is rotated in the direction of arrow E in the figure, the products 72 and the like that have fallen onto the conveyor 6 are further conveyed by the belt 13 to the product storage box 9 side, and the end of the conveyor 6 The product is ready to be stored in the product storage box 9 at the end.

Next, the external control section 3 constitutes an external control means,
It is mainly composed of a microcomputer, and as shown in FIG. 3, in addition to a central processing unit (CPU) 21, it is connected to the central processing unit 21 via a data bus 22, and stores processing procedures. Memory (ROM) 23 and
A memory (RAM>24) for storing data on the laser press operation status from the NC control unit 63 and data for instructions to the NC control unit 63, and a timer 25 for monitoring the operation confirmation status of the sorting mechanism 2. , external control unit 3 and N
It is composed of a parallel interface 26 for controlling the exchange of signals with the C control section 63, and a serial interface 27 for controlling the interface between the external control section 3 and various external devices.

FIG. 4 is a flowchart showing an example of a program stored in the memory (ROM) 23 as a processing procedure of the external control unit 3. Therefore, along with this flowchart,
Next, the operation of the sorting apparatus according to the present invention will be explained.

First, in this embodiment, in addition to the laser processing instructions, the NC data automatically indicates whether the laser processed object is the product 72 or the waste materials 73, 74, 7.
Identification data is added to determine whether N
It is then transferred to the C control unit 63. Then, based on the NC data, the laser brace rod 67 and the work clamp 69 are operated via the NC control section 63, and predetermined laser processing is performed. A data signal processed by .75 is sent out from the NC control section 63. The data signal at this time is judged by the external control unit 3 (steps 101, 102), and the product 7
2 or waste material 73, 74, or 75, the process proceeds to the next step. On the other hand, if the external control unit 3 determines that it is the product 72 based on the NC data,
turning the swing cylinder 8 into the off state step 103);
The piston part 8b is made to protrude from the cylinder part 8a. Then, the product receiving portion 5 rotates in the direction of arrow a in FIG. 2(b). When a sensor (not shown) detects that the product receiving section 5 has reached the end in the direction of arrow a (step 104), a pulse as a separation preparation signal is sent from the external control section 3 to the NC control section 63. sent (step 105)
). Further, when this separation preparation signal is received on the NC control section 63 side, the shooter 68 is controlled by the NC control section 63.
is lowered in the direction of arrow C from the position shown by the solid line in FIG. 2(b) to the position shown by the one-dot chain line, and the tip 68a of the chute 68 and the upper end 5b of the product receiving part 5 are in a substantially continuous state. As a result, the product 72 carried onto the chute 68 is moved from the chute 68. Product receiving part 5
It slides on the top and falls onto the conveyor 6 (step 106).
The product 72 that has fallen onto the conveyor 6 is conveyed by the belt 13 in the direction of arrow E in FIG. 2(b), and is stored in the product storage box 9. On the other hand, the shooter 68 is
When the product 72 passes through the chute 68, the product 72 is detected by the magnetic sensor 70 (step 10).
7), this is input to the NC control section 63. Then, in response to the command from the NC control section 63, the chute 68 rises in the direction of the arrow to the position shown by the solid line in FIG. Ru. In this case, when a plurality of products 72 are processed in succession, the tilt of the chute 68 may not be returned each time, but may be returned after all products have been processed. Furthermore, when handling large products that cannot be slid down on the chute 68, information is added in advance using NC data to prevent the chute 68 from tilting.

Conversely, when the external control unit 3 determines that the data signal after laser processing is the waste material 73 (or 74.75), the turning cylinder 8 is turned on (step 108), and the piston part 8b is moved partially into the cylinder. 8a side, the product receiving portion 5 rotates in the direction of arrow A in FIG. 2(a). Then, when a sensor (not shown) detects that the product receiving portion 5 has reached the end in the direction of arrow A (step 109>,
A pulse as a separation preparation signal is sent from the external control section 3 to the NC control section 63 side (step 110), and when this separation preparation signal is received on the NC control section 63 side, this N
Under the control of the C control unit 63, the shooter 68 moves to the position shown in FIG.
) from the position indicated by the solid line to the position indicated by the dashed line
descend in the direction.

Then, the tip 68a of the shooter 68 and the upper end 5b of the product receiving portion 5 are separated by a large distance, and a large gap is formed. Then, the waste material 73 carried onto the chute 68 (
or 74, 75) slides on the chute 68 as shown by the black arrow G, and then falls directly into the waste material storage box 7 through the gap and is stored (step 111).
.

On the other hand, when the waste material 73 (or 74.75) passes through the chute 68, the waste material 73 (or 74.75) is detected by the magnetic sensor 70 (
Step 112), this is input to the NC control section 63. Then, in response to a command from the NC control unit 63, the chute 68 rises in the direction of the arrow to the position shown by the solid line in FIG. 2(a), thereby eliminating the tilt of the chute 68 and continuing the next program. It turns out. In this case, when the waste materials 73, 74, and 75 are processed continuously, the inclination of the chute 68 is not returned each time, but is returned after the waste material 75 is processed, as in the case of the product 72. Sometimes it is possible to do so.

Therefore, in the sorting according to this embodiment, the laser press machine 1 equipped with the device can automatically sort the products 72 processed by the laser press main body 62 and the waste material 73 (or 74.75). , improving work efficiency and productivity.

In addition, although the above example describes the case where processing is performed using a laser press machine, this is not limited to processing using a laser press machine, and may be applied to a wide range of general processing machines. It is something.

<Effects of the Invention> As explained above, in the processing machine according to the present invention, the classification between products and waste materials is performed using an external control means that identifies whether a processed part is a product or a waste material. Based on this identification data, the operation of the sorting means can be switched to discharge the product or waste material in the appropriate direction, making it possible to automate the sorting of processed products and waste material. , and productivity can be improved.
