JPH01139225A - Releasing method for molded product - Google Patents

Abstract

PURPOSE:To simplify the structure and speed up the action by rotating an arm of a releasing device going into a molding machine, matching the extruding direction of a molded product with circumferential movement at the time of arm rotation and releasing the molded product. CONSTITUTION:An arm 2 of a releasing device main body 1 which can rotate around a point 0 goes straight and stops at a waiting point for release in a mold 6 of a molding machine 7. The releasing device main body 1 rotates around the point 0 as a center and moves in the circumferential direction. The same moves in the direction in which a molded product extruding mechanism 8 and a molded product retaining section 4 retains a molded product 5. The releasing device main body 1 rotates in the reverse direction after retaining, and molded product 5 is released out of a mold 6 simultaneously with the extraction of the extruding mechanism 8. After that, releasing action is completed by moving the arm 2 backward. As above-mentioned, as a linear movement section is not required for the arm 2 of the releasing device 1, the structure is simplified and lightened. Further, the straight movement of the arm itself can be speeded up.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for removing a molded product from a molding machine.

[Summary of the invention]

The present invention provides a method for taking out a molded product from a molding machine,
The arm of the take-out device that has entered directly into the molding machine is
The structure of the take-out device is simplified by rotating around the take-out device side and taking out the molded product by matching the extrusion direction of the molded product from the molding machine and the direction of the circumferential movement of the molded product holder when the arm rotates. This allows the take-out operation to be performed at high speed.

[Conventional technology]

The conventional method for taking out molded products is to move the tip of the arm that has entered the molding machine linearly or through rotational motion into the molding machine, and then a linear movement mechanism is installed, and a molded product holder is attached to this part. The molded product was taken out by aligning the molded product extrusion direction with the molded product or by moving the entire arm that entered the molding machine in the molded product extrusion direction. An example of this will be explained with reference to FIG. 2. The arm 2 of the molded product take-out device 1 moves straight and stops at the standby position for taking out the mold 6 of the molding machine 7, and then the end of the arm to which the molded product holding part 4 is attached. Linear motion mechanism 3
After moving in the moving direction of the molded product extrusion mechanism 8 and holding the molded product, the arm tip moving mechanism retreats, and then the arm retreats, thereby completing the take-out operation.

[Problem that the invention seeks to solve]

However, the conventional ejecting method requires a mechanism to perform linear movement at the tip of the arm, or a mechanism to move the entire arm in the direction of extruding the molded product, and the ejecting device cannot have a simple structure. Since the weight of the mechanism of the moving part is large, there is a problem in that high-speed take-out operation cannot be performed.

Therefore, the present invention is intended to solve these problems, and its purpose is to simplify the structure of the take-out device,
Furthermore, it is an object of the present invention to provide a method for removing a molded product that realizes a high-speed removal operation.

[Means for solving problems]

In order to solve the above-mentioned problems, the method for taking out a molded product of the present invention, when taking out a molded product from a molding machine, rotates an arm of a take-out device that has linearly entered the mold of the molding machine around the take-out device side. The molded product is taken out from the molding machine by matching the extrusion direction of the molded product extrusion mechanism of the molding machine with the circumferential movement of the molded product holder when the arm rotates.

[Effect]

According to the above method of the present invention, the arm of the take-out device that enters the molding machine does not require a linear movement mechanism in the direction of extruding the molded product. By only slightly rotating the take-out device side of the take-out device arm, which is lightweight without the drive mechanism, sufficient movement in the molded product extrusion direction can be obtained for the take-out operation, making high-speed take-out operations possible.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings, taking as an example a case where a robot is used as a take-out device. In FIG. 1, the arm 2 of the take-out device main body 1, which can rotate around point 0, moves straight and stops at the take-out standby point in the mold 6 of the molding machine 7, and the take-out device main body 1 rotates around point 0. By moving in the circumferential direction, the molded product holding section 4 moves in the moving direction of the molded product extrusion mechanism 8 and holds the molded product 5. After holding, the take-out device main body 1 rotates in the opposite direction and the molded product 5 is taken out from the mold 6 along with extrusion by the extrusion mechanism 8. Thereafter, the arm 2 retreats, thereby completing the take-out operation.

In the embodiments described above, the arm 2 of the take-out device 1 does not require a linear motion part, so the structure becomes simple and lightweight. Therefore, the linear movement of the arm itself can be made faster, and the movement in the molded product extrusion direction can be achieved by a slight rotation of the take-out device main body l, so that a high-speed take-out operation can be realized.

〔Effect of the invention〕

As described above, according to the present invention, the arm of the take-out device that has entered the molding machine is rotated, and the molded product is taken out by matching the molded product extrusion direction with the circumferential movement when the arm rotates. This eliminates the need for a movement mechanism in the extrusion direction of the molded product, resulting in a simple structure and advantages.

Furthermore, the weight of the arm can be reduced, and movement in the molded product extrusion direction can be achieved by a slight rotation of the arm, which has the effect of speeding up the take-out operation.
