Description

Automatic Variable Transport Robot

The present invention relates to an automatic variable transfer robot (Automatic Variable Robot), an automatic variable transfer robot capable of unmanning all the processes of the molding processing line with a free combination and arrangement of the system when the production system is converted by realizing a wide processing range of the press equipment (Auto Flexible Transfer Robot).

As shown in Fig. 5, a line transfer of a line production system for continuously transferring a processed product by a transfer unit connected to a press line as shown in Fig. 5 (A), as shown in Fig. 6 Shuttle feeder (B) of a single production system that transfers a processed product by a line feeder unit coupled to a press line, or a single feed that is transferred by a transfer unit mounted on a medium-large press as shown in FIG. Transfer presses (C) of a multi-process production system and system line feeder robots (D) conveyed by an arm to a standardized multi-processing production system as shown in Fig. 8 are known.

In the conventional automation line, when a workpiece is sequentially entered by a press peripheral device, that is, an uncoiler, a leveler, a roll feeder, or the like, a standardization of a transfer unit and a single press that are collectively coupled to the press line is performed. Limited molding automation has been achieved, limited to the progressive process, which transfers multiple processes by means of conventional equipment.

More specifically, the loading / feeding / drawing process of the workpiece is performed by the loader in the three-element press work, and the conventional automation unit is continuous in the transfer stage except for the take-out function by the unloader. It is responsible for feeding role of production system.

It is an automatic equipment that is suitable for mass production system that requires the productivity of multi-process products of secondary processing or more by line continuous transfer system by using peripheral equipment as an essential auxiliary device.

However, conventional automation units and systems have problems in production operating systems that are significantly limited.

Dedicated automation of single-sequential continuous processes lacks versatility in the single-shot and minor-process multi-process production systems required by the production site conditions. That is, there is an inadequate factor in producing multiple kinds of products simultaneously under the same press equipment conditions.

Particularly, the production system such as diversification of molding type, conversion of processing process, change of output of same type, change of unit of main device and peripheral device, line retry-out, idle unit generation, etc. The system compatibility with the conversion was very low.

In addition, there is an irrationality of production management preservation, such as shutdown of production line and supply imbalance between processing processes when system trouble occurs, and it requires an integrated facility system with essential peripheral devices in preparation for the general effect of automation introduction. It became.

In order to solve the problems described above, the present invention is able to exert the versatility and compatibility in the operation of all the molding processing production systems by freely combining and arranging the line continuous operation as well as the single operation in the existing press equipment situation. It is a single facility that has a complex function of extracting / taking / transporting. It can provide the Auto Flexible Transfer Robot as a compact unit that minimizes the retry-out cycle when the production system is switched, as well as the selection of peripherals. To make that possible,

The above object is a profile of a slide table (Slide Table) in which the input / take / transfer function of the workpiece in the press work is consistently guided, the drive device is fixedly installed;

A guide block (Guide Block) mounted with a vertical guide member guided in association with a drive unit of the table and a plurality of arms operatively connected to the drive unit;

It is arranged in combination with a press panel and can be achieved by means of a configuration having actuating means correlated with press control within a variable and adjustable stroke range.

As shown in Figs.

The robot has a frame upper side table 11 as a profile structure so as to move the unit frame 10 and the processed workpiece in the transverse direction with respect to the unit frame.

The robot also has a guide block 08 fixed to the slide table 11, which is the initial loading of the slide table 11 to transfer the workpiece in the transverse direction, as shown in FIG. It is configured to move vertically between the loading position and the final unloading position.

In the lower part of the unit frame 10, a cable carrier 17 is rotatably mounted.

At the bottom of the slide table 11, a pair of arms 09 mounted on the arm plate 05 is fixed. One of these arms is operable on one side of the guide block 08 and the other on the opposite side. It is connected.

Accordingly, the arms may move laterally and vertically with respect to the transport path defined by the guide block 08 according to the operation of the slide table 11.

In addition, the robot is provided with a control panel 18 in combination with the press panel. The control panel 18 is provided with a plurality of switch keys that can be selectively pressed to operate a robot arranged in a combination of press work lines in the form shown in FIG.

In the progressive process system, a first transfer table (Destocker) having a loading device for inserting the workpiece into the press on one side of the robot is configured, and on the other side, the first processed material is continuously taken out by the press. A second transfer table (SHOOT) for transferring is configured.

As shown in Fig. 3, the robot is provided with a servo motor 01 for driving the slide table 11 through a power transmission device including a gear to transfer the workpiece in a horizontal plane, and the support frame 04 has an air cylinder 02. Is provided.

The air cylinder (02) is operated by the vertical movement of the arm by the vertical guide member 14 for the attachment and detachment position of the workpiece.

That is, the servo motor 01 has its main body fixed to the unit frame 10, and the pinion 12 mounted on its output shaft and the rack 13 fixed to the slide table 11 have a tee cross (T-). It is composed of profile structure in combination with bearing unit (06) arranged in cross shape.

Therefore, by energizing, the slide table 11 is moved left and right by sliding in the lateral direction by the normal and reverse operation of the servo motor.

The vertical guide member 14 is provided on each side of the slide table 11, one each is configured to guide the arm up and down by the cylinder.

When explaining the operation of the robot,

When the slide table 11 which is stopped at the neutral position is transferred to the left position by the servo motor 01 controller to the specified position of the first transfer table and stopped, the operation of the air cylinder 02 by the signal Signal is performed. The left arm descends to hold the workpiece.

At the same time, the Right Arm works in parallel to take out the finished workpiece.

The raised left arm is centered with a press mold and the workpiece is put into the mold, and the workpiece held in the light arm is placed on the second transfer table for the next process.

The robot, which has performed the input / discharge / transfer process, returns to its original neutral position and the following process is re-executed as desired.

The robot inputs, extracts, and transfers a variable stroke, which is a rotational distance of the slide table 11, an adjustment stroke, which is a longitudinal conveying range of the guide block 08, and a selection operation of switch keys of the control panel. It operates under the control of a servo control system having a memory that stores data for determining the cycle time and position accuracy provided in cooperation with the weight, size and shape of the quality workpiece.
