[Industrial applications]

 The present invention relates to an arm type robot used in a plastic injection molding machine to eject a molded product (including a runner) from a molding die device.

[0002]

[Prior art]

 In a plastic injection molding machine, as a means for ejecting a molded product from a molding die device, an arm-type robot that uses an air cylinder and is capable of expanding and contracting and swinging in three directions: ascending / descending, advancing / retracting, and turning. Has been adopted. The chuck means C'which is opened and closed by air is fixed to the support plate 13 'at the end of the arm portion of the take-out robot (see FIG. 5) to chuck the target article.

[0003]

[Problems to be solved by the device]

 There are various types of take-out robots that eject molded products or runners from the molding die. Among them, the cheap type is the arm type robot. Generally, the arm type robot is used by being fixed on a fixed side plate of a plastic injection molding machine.

As shown in FIG. 5, the chuck means C'is of a type that grips an object to be chucked by opening and closing chuck jaws 1'which face each other in parallel by air. Here, since the chuck means C ′ is directly fixed to the support plate 13 ′ at the tip of the arm portion of the arm type robot, when the position of the chucked object is adjusted by rotating the rotary table, the chucked object C ′ is moved to the chucked object. As a result, the supporting plate also rotates, and the chuck means also rotates, so that when the molded product or runner is taken out, the chuck claw at the tip of the chuck means does not contact the object to be chucked except at a specific position. It was impossible to adjust them in parallel. As a result, the chuck operates in a relationship in which the chuck claw is not parallel to the object to be chucked, so the reliability of the chuck is lacking, and a chuck error often occurs.

In view of this, the present invention relates to an arm type robot that is attached to a plastic injection molding machine and is used as a means for ejecting a molded product from a molding die device when adjusting the position of a chucked object. It is an object of the present invention to allow the chuck claws of the chuck means to be adjusted parallel to the object to be chucked regardless of the position of the object to be chucked.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, in an arm type robot, chuck means attached to the tip of the arm is attached via intermediate holding means attachable to the arm at an arbitrary angle in the rotational direction. .

[0007]

【Example】

 Hereinafter, the details of the present invention will be described with reference to the preferred embodiments shown in the accompanying drawings.

In FIG. 1, the arm type robot R of the present embodiment is a type that can be expanded and contracted and swung in three directions of an air cylinder (not shown) as a driving source: ascending / descending, advancing / retracting, and turning. Generally, the take-out arm type robot is installed on the stationary platen 21 of the plastic injection molding machine. After being installed on the stationary side platen 21, the chuck means C chucks the object to be chucked by adjusting the expansion / contraction stroke of the rotary table 11, the front-rear adjustment slider 12, and the cylinders. Mounting adjustments are made so that the mold device 22 is discharged.

In the present invention, the chuck means C is mounted via the intermediate holding means A that can be attached to the support plate 13 at the tip of the arm portion of the arm type robot R as shown in FIG. It is attached. When the nut 2 fastened to the threaded portion of the intermediate holding means A is loosened, the chuck means C fixed to the intermediate holding means A becomes freely rotatable with respect to the support plate 13, and any angle adjustment is possible. become. When the desired angle is adjusted and the nut 2 is tightened again, the chuck means C is fixed to the support plate 13, and the chuck claw 1 of the chuck step C can be made parallel to the object to be chucked.

Next, an adjusting method when the intermediate holding means A of this embodiment is used will be described. After the molding is completed and the molding die apparatus is in the mold open state, in the state where the chucked object 23 formed by molding is present, the rotary table 11, the front-back adjusting slider 12, and the cylinders Adjust the expansion / contraction stroke (Fig. 3 (a), (b)). In this adjustment, if the chuck claw 1 at the tip of the chuck means C chucks the object 23 to be chucked in parallel, the adjustment is completed at that stage. As shown in FIG. 4 (a) showing the details of the chuck means C in FIG. 3 (b), when the chuck claw 1 and the object to be chucked 23 are not parallel, the intermediate holding means A is adjusted to adjust the chuck means C. Only by rotating it, the chuck claw 1 is adjusted to be parallel to the chucked object 23 (FIG. 4 (b)).

According to this embodiment, for a molding die apparatus in which the position of the chucked object 23 is different, and for any molding die apparatus, the chucked object 23 to be chucked from the molding die apparatus. On the other hand, since the chuck claws 1 of the chuck means C of the arm type robot R can be adjusted in parallel, the reliability of the chuck can be improved.

In the present embodiment, the intermediate holding means A is fixed to the support plate 13 at the end of the arm portion of the arm type robot R by screwing using the nut 2, but the fixing method is the same as in the present embodiment. Not limited to For example, another fixing method such as connecting and fixing from the side with a set screw can be adopted.

[Effect of device]

 According to the configuration of the present invention, in an arm type robot, which is an inexpensive type as a take-out robot for ejecting a molded product from a molding die apparatus, the chuck claws of the chucking means of the take-out robot are covered with respect to different molding die apparatuses. Since it can be adjusted parallel to the chuck object, the reliability of the chuck is improved. Along with this, it is possible to implement formally operation without delay and improve productivity.
