Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die accommodating device for accommodating various interchangeable dies for a punch press machine for punching a workpiece.

[0002]

2. Description of the Related Art A punch press machine having a replaceable die is disclosed in Japanese Utility Model Laid-Open No. 5-28519. This punch press machine includes a tool changer (ATC), a tool magazine, a tool change robot, a tool tower, and a controller.

This apparatus reads a die to be used in advance by a machining program, and when it is determined that the die to be used is not in the tool magazine from the information of the die stored in the tool magazine, the number of punches is determined. And, when the machining time calculated from the movement distance of the work is longer than the time required for exchanging the mold between the tool tower and the tool magazine, the mold change of ATC is stopped and the tool tower is It is a configuration in which a certain die is replenished to the tool magazine and the waste die housed in the tool magazine is returned to the tool tower. According to this configuration, only the molds stored in the tool magazine are used, and when the punching of the same shape is continuously processed within the range of this mold type, the selective replacement of each mold is performed for a short time. It has the advantage that

Further, the one disclosed in Japanese Patent Laid-Open No. 63-27308 is a device in which a plurality of molds to be replaced are mounted on one pallet and the pallets are replaced in units. In this mold exchanging device, a part of a plurality of molds provided on the turret is configured to be exchangeable,
A plurality of molds are stored in the storage device. This mold exchanging device has a structure in which, when exchanging a die, punching is interrupted, and then a pallet provided on a turret is rotated to an exchanging position for exchanging the die. Therefore,
In order to reduce the machining interruption time as much as possible, we have devised a method to reduce the number of mold changes by setting multiple molds on one pallet.

[0005]

However, in the first device, when a large number of molds to be used are not present in the tool magazine, the machining time is not always the case between the tool tower and the tool magazine. It cannot be expected to take longer than the time required to replace the mold in, and in that case, the mold replacement time becomes longer. It can be easily inferred that this becomes more remarkable as the number of molds stored in the tool tower increases. Further, the molds are stored in two places, the tool tower and the tool magazine, which complicates the configuration and increases the installation area.

Further, in the second apparatus, in order to use all the plurality of molds actually set on one pallet in one mold exchange, it is very complicated to manage the molds. Since it is necessary, it is not actually done, and often only one of the multiple molds set on one pallet is used and the other molds are not used, As a result, the number of mold changes cannot be reduced. For this reason, the management of dies for the purpose of effectively using the dies set on the pallet becomes very complicated, and in reality, the optimal management for the work content is not performed. Is often left semi-fixed on the pallet. Therefore, even if a plurality of molds are replaced by one mold replacement, the effect is not so remarkable. Due to the above problems, production with only replacement molds is inefficient, so in many cases,
Since it will be produced in combination with a fixed die (die that can be replaced manually), there will be limits to the unmanned production of high-mix low-volume production, which will continue to improve in the future, and the improvement of long-term operation.

The present invention has been made to solve the above problems, and can shorten the time required for die replacement,
Another object of the present invention is to provide a die housing device for a punch press machine that can save the installation area of the die housing portion.

[0008]

In order to achieve the above object, according to a first aspect of the present invention, there is provided a die accommodating device for a punch press machine, wherein a die for punching is exchangeable with the punch press machine. In a die storage device of a punch press machine for storing (50, 60), a storage section (2) having a plurality of rotatable storage shelves (4) for storing a plurality of dies, a storage section and a punch press. A delivery device (3) for moving a die to and from a die exchanging unit of a machine, and a die position storage unit (33) for preliminarily storing types and storage positions of a plurality of die stored in the storage unit. ) And a machining command such as a machining program for the work material are input, and a shelf position exchanging processing unit (32) for exchanging a used die in a new die accommodating location taken out from the storage table. And the replacement processing of the shelf position replacement processing unit The transfer device and operation control Hazuki, mechanism control unit that performs replacement of the mold (35), is characterized by comprising a.

Further, as described in claim 2, the delivery device is provided on the elevating mechanism (9) for moving the elevating stage (10) up and down along the storage section (2). ,
Two clamp mechanisms (13), which are respectively provided on the side facing the storage section and the side facing the mold exchanging section, and which can clamp the mold, and the clamp mechanism can be swung on the lifting platform to be reversed. And a slide mechanism (17) for moving each of the clamp mechanisms with respect to the storage section and the mold exchanging section.

According to a third aspect of the present invention, the die exchanging portion of the punch press machine is provided coaxially with the rotating turret (45), and is rotatable independently of the turret. It can be composed of an exchange arm (47) for loading and unloading the mold (50, 60) with respect to the turret.

Further, as described in claim 4, the die exchanging portion of the punch press machine is a turret (45) which rotates.
Therefore, the delivery device (3) can be configured to load and unload the mold (50, 60) with respect to the turret.

[0012]

When a machining command for using the new dies 50 and 60 is input from the machining program by the punch press, the shelf position change processing unit 32 stores the corresponding dies in the storage unit 2. The position of the storage rack 4 is obtained by referring to the mold position storage means 33. At the same time, the shelf position replacement processing unit 32 carries out a replacement process for storing the molds that have been used by the punch press machine in the storage rack 4. The die replacement is performed by operating the delivery device 3 under the control of the mechanism control unit 35. The delivery device 3 moves a new mold from the storage unit 2 to the punch press machine, and also moves a used mold from the punch press machine to the storage unit. The used mold is stored in the storage rack 4 immediately after being taken out. Therefore, the mechanical operation can be simplified and the mold can be taken out quickly.

Next, FIG. 7 is a block diagram showing the control section 30 of the mold accommodating apparatus of the present invention. The processing command for the press machine main body includes a selection command for the fixed mold 46 provided on the turret 45 and replacement molds 50, 6 according to the processing shape.
The operation information of 0 is included, and the operation of each component of the press body for continuously punching the plate material is prepared in advance as a machining program. This machining command is also input to the control unit 30, and the control unit 30 controls to supply or store the replacement dies 50 and 60 in the machining command to the press machine.

The use die selecting means 31 extracts and outputs the use instruction to the shelf position exchange processing section 32 each time a use instruction for the replacement dies 50, 60 is issued during the machining instruction. The mold position storage means 33 stores the positions of all the upper and lower molds 50 and 60 in the storage unit 2 arranged at the three locations. FIG. 8 is a diagram virtually showing a storage state inside the mold position storage means 33. In this way, three storage units 2 are provided.
Fixed addresses are set in correspondence with the number of the engaging grooves 5 of the storage shelves 4 having a plurality of stages a to 2c. here,
Since the upper and lower molds 50 and 60 are used in a pair, one address may be set in the upper and lower molds 50 and 60. On this address, the dies 50 housed in the respective engagement grooves 5,
The 60 types (machined hole shape, punch diameter, etc.) are stored as data in a table format. The data on the address is updated by the die replacement operation as described later.

The shelf position replacement processing unit 32 reads the address and data of a mold to be newly used from the mold position storage means 33 based on the information of the mold to be used and writes it in the RAM 34. The RAM 34 has storage areas corresponding to the dies 50 and 60 that can be mounted on the turret 45, and temporarily stores the addresses and data of the dies during the period of being taken out of the storage rack 4 and being carried out to the press machine. Store. Also,
The RAM 34 is overwritten with the data of the metal mold stored at the address of the new metal mold taken out every time a metal mold taken out from the press machine and stored in the storage rack 4 is generated. After that, the data of the storage mold is stored again in the corresponding address of the mold position storage means 33.

Therefore, the data of the new mold is stored in the predetermined area of the RAM 34 while the address in the mold position storage means 33 is lost while the data of the new mold is taken out. In this way, the mold position storage means 33 stores the position information and the mold types of all the molds stored in the storage unit 2 in an updatable manner.

The mechanism control unit 35 centrally controls the operation of the entire mechanical unit of the die accommodating apparatus 1 according to a predetermined sequence. Specifically, the storage unit 2 controls the shelf rotating mechanism 4 and the lifting mechanism 9 of the storage shelf 4. The delivery device 3 controls the turning mechanism 11, the clamp mechanism 13, and the slide mechanism 17. The control of the mechanism control unit 35 will be described in detail in the explanation of the operation of the device described below.

Next, a basic take-out operation of the mold accommodating apparatus having the above structure will be described. Based on the processing command, the control unit 30 of the mold housing device uses the upper and lower molds 5 to be newly used.
The position information of 0 and 60 is obtained from the mold position storage means 33.

Here, the exchange dies 50 and 60 are stored in the storage unit 2.
Upper and lower engaging grooves 5 of the uppermost storage shelf 4 (4a, 4b) of c
If they are respectively stored in the
First, the elevating mechanism 9 of the storage unit 2 is operated to move the elevating table 10 upward to the uppermost position (the same height position as in FIG. 2). At the same time, the shelf rotation mechanism 6 is controlled to rotate to rotate the storage shelf 4, and the corresponding upper and lower molds 50 and 60 are transferred to the delivery device 3.
Move to a position facing. Further, the swivel mechanism 11 of the delivery device 3 is controlled, and the clamp mechanism 13 is mounted on the lift 10.
Is rotated toward the storage unit 2 by a predetermined angle.

Next, the slide mechanism 17 of the delivery device 3 is controlled to move the clamp mechanism 13 forward in the direction of the storage shelves 4 (4a, 4b). At this time, the arm 14 of the clamp mechanism 13 is controlled to be open. After this, as shown in the plan view of FIG. 9 and each operation diagram of the side view of FIG. 10, the arm 14 of the clamp mechanism 13 is closed and the slide mechanism 17
By retreating, the upper and lower molds 50 and 60 can be held and taken out by the upper and lower arms 14 and 14, respectively.

The positioning pins 53 and 63 of the upper and lower molds 50 and 60 are the positioning pieces 4aa provided on the storage shelf 4,
Since the clamp mechanism 13 is locked to 4 bb and is prevented from rotating, the clamp mechanism 13 can be moved horizontally only by the upper and lower molds 50,
60 cannot be taken out (stored). Therefore, when the upper and lower molds 50 and 60 are taken out (stored), the slide mechanism 1 is lifted up by a predetermined distance (10 mm) while holding the upper and lower molds 50 and 60 therebetween.
7 is set back.

By moving the slide mechanism 17 backward, FIG.
As shown in FIG. 3, the upper and lower molds 50 and 60 are located in the central portion of the lift 10. Next, the turning mechanism 11 is actuated to turn the direction of the clamp mechanism 13 to the reference position shown in FIG. 1, and then the lifting mechanism 9 is lowered to the lower position. This allows
The delivery device 3 is in a state of facing the exchange arm 47 of the press machine main body, and in this state, the turning mechanism 11 turns 180 degrees, whereby the upper and lower molds 50, 60 are moved.
Turn to the side. Then, as the slide mechanism 17 moves forward, the upper and lower molds 50, 60 move to the position of the replacement arm 47, and the upper and lower molds 50, 60 with respect to the replacement arm 47.
Can be delivered. The upper and lower molds 50 and 60 held by the exchange arm 47 are mounted on the turret 45.

In the above-mentioned operation, only the clamp mechanism 13 and the slide mechanism 17 on one side of the delivery device 3 are operated and the mold is taken out from the storage section 2. However, this device is new. Used molds are stored in the place where the molds are taken out. The replacement operation will be described below.

Based on the processing command, the control unit 30 of the mold housing device obtains the position information of the upper and lower molds 50 and 60 to be newly used from the mold position storage means 33. At this time, the shelf position replacement processing unit 32, the storage unit 2a ~ 2c information about which mold is stored, information on the height position of the storage rack 4 in the corresponding storage unit 2, and the storage rack. The information of the corresponding position (position of the engaging groove 5) within 4 is obtained. The address and data corresponding to the corresponding mold are temporarily stored in the RAM 34. Then, in the mold storage device 1, the mechanism control unit 35 takes out a new mold from the storage unit 2 and moves it to the lower reference position facing the exchange arm 47, as in the above-described operation.

At this time, on the press body side, the used upper and lower molds are taken out of the turret 45 by the exchanging arm 47 in parallel and moved to the same reference position.
After that, at this reference position shown in FIG. 1, the empty clamp mechanism 13 facing the exchange arm 47 moves forward to nip and receive the used mold from the exchange arm 47.
The new molds 50 and 60, which are clamped by the opposite clamp mechanism 13, are delivered to the exchange arm 47 by turning once.

At this time, the shelf position replacement processing unit 32 determines that the RA
The data of the used mold is read from M34, and this data is written on the address of the new mold. As a result, the used mold can be stored in the storage place of the mold that has been newly taken out. In this state, the new mold data is stored only in the predetermined area of the RAM 34 in a state where the address in the mold position storage means 33 is lost. It is written on the address taken out as a new mold and stored again in the mold position storage means 33.

Then, on the press machine body side, immediately after the exchange arm 47 delivers the used die to the delivery device 3,
Since a new mold is delivered, the new mold can be immediately mounted on the turret 45, so that the replacement time can be extremely shortened.

On the other hand, on the side of the mold accommodating device 1, the operation of accommodating the used mold in the storage unit 2 taken out is performed in parallel. This return operation can be performed by reversing the operation of each part during the take-out operation for the new mold. The above-mentioned mold replacement operation is shown in the flowchart of FIG.

In the above embodiment, one clamp mechanism 13 of the delivery device 3 is initially in an empty state, and the exchange arm 4
7 has been described as a configuration for receiving the used dies 50, 60 from the above. However, the clamping mechanism 13 of the delivery device 3 may be configured to hold the previously used dies 50, 60. it can. As a result, immediately after the delivery device 3 receives the new die 50, 60 stored in the predetermined position of the storage shelf 2 by the input of the die replacement command,
The used dies 50 and 60 of the last time can be immediately stored in this place only by reversing. After this, the delivery device 3
After the used mold of this time is received from the replacement arm 47 by one of the clamp mechanisms 13, a new mold is delivered to the replacement arm 47. In this way, the used mold 5 of the previous time is added to the one clamp mechanism 13 of the delivery device 3.
With the configuration in which 0 and 60 are held, the operation of the apparatus is not wasted, and it becomes possible to improve the efficiency of taking out and storing the mold.

In the above-described embodiment, the press machine main body is provided with the arm mechanism 47, and the arm mechanism 47 is configured to perform the mounting and removing operations of the upper and lower molds 50 and 60 with respect to the turret 45. The mold accommodating device does not require the arm mechanism 47. That is, it is also possible to configure the delivery device 3 to directly perform the loading and unloading operations of the mold on the turret 45 without providing the arm mechanism 47 in the press body.

In the above embodiment, three storage units 2 are provided and one delivery device 3 transfers the molds. However, only one storage unit 2 may be provided. ,
It is also possible to add more than three units. In this case, a plurality of storage units 2 and delivery devices 3 may be provided on the circumference of the turret 45. Further, in the control unit 30 having the above-described configuration, the address and the data are used to overwrite in the RAM 34 for the replacement of the mold, but the configuration is not limited to the overwrite, and the copy and deletion of the data are used to replace the old and new data. Other methods may be used as long as it is possible to determine which kind of mold is stored in the storage unit 2 in the storage unit 2.

[0043]

As described above, according to the present invention, since a die that has been used in a punch press machine is replaced and stored in a place where a newly taken out die is stored, the die can be replaced. This time can be shortened and the operating efficiency of the device can be improved. Further, the delivery device provided between the storage table and the punch press has a symmetrical clamp mechanism, and the clamp mechanism is configured to be reversible,
In the replacement storage, other molds can be stored immediately after being taken out, and this can be performed by a simple mechanism and control operation. At the same time, the installation area can be saved.
