In the conventional molded product take-out machine, the take-out time per cycle of the take-out operation of the molded product take-out mechanism is about 0.65 seconds. However, in the conventional structure, if an attempt is made to further increase the take-out time, the vibration of the gantry becomes large, and there arises a problem that the molded product immediately after molding is deformed due to this vibration.

An object of the present invention is to provide a molded product take-out machine capable of speeding up a take-out operation as compared with the conventional case.

The molded article take-out machine to be improved by the present invention includes a gantry and a molded article take-out mechanism attached to the gantry. In a conventional gantry, a plurality of metal column members, a plurality of metal upper beam members connecting a plurality of upper ends of a plurality of metal column members, and a plurality of a plurality of lower ends of a plurality of metal column members are connected.

A metal top plate connected to the skeleton structure so as to close at least a part of the upper opening of the skeleton structure, and a metal bottom plate connected to the skeleton structure so as to close at least a part of the lower opening of the skeleton structure. And a metal connecting member that is coupled to the skeleton structure and connected to the molding machine. The molded product take-out mechanism is attached to the metal top plate. In such a molded product take-out machine, in the present invention, a plurality of metal column members, a metal upper beam member, and a metal lower beam member are joined, a frame structure and a metal top plate, a metal bottom plate, and a metal side plate. All of the connections are achieved by welded joints. In the frame structure, a plurality of metal intermediate beam members connecting the plurality of metal column members are joined by welding at positions between the plurality of upper ends and the plurality of lower ends of the plurality of metal column members. .. Welded joints (joint structures formed by welding) have stronger mechanical strength than bolt-nut joints, screw joints, and inset joints. Therefore, the strength of the frame base can be made higher than before. Further, when the metal intermediate beam member is joined by welding, the reference position of the molded product take-out mechanism (for example, the tip position of the take-out head, etc.) when the molded product take-out mechanism operates is higher than that in the case without the metal intermediate beam member. The amount of displacement can be halved. Therefore, the take-out speed can be made faster than before.

The plurality of metal intermediate beam members may consist of a plurality of outer intermediate beam members connecting the plurality of metal column members in the circumferential direction, or may include a plurality of outer intermediate beam members connecting the plurality of metal column members in the circumferential direction. It consists of an inner intermediate beam member arranged in a space surrounded by a plurality of outer intermediate beam members and connected to the plurality of outer intermediate beam members, or a plurality of outer surfaces connecting a plurality of metal column members in the circumferential direction. One or more insides of a plurality of metal column members arranged in a space surrounded by an intermediate beam member and a plurality of outer intermediate beam members and connecting two metal column members facing each other with the space in between. It consists of an intermediate beam member. In any configuration, the amount of displacement of the gantry when the molded product take-out mechanism operates can be halved as compared with the case where there is no metal intermediate beam member. In particular, when the inner intermediate beam member is provided, the mechanical strength can be increased and the displacement amount can be reduced by 18% or more as compared with the case where the inner intermediate beam member is provided. Therefore, the take-out speed can be further increased.

It is preferable that the upper surface or the lower surface of the metal intermediate beam member is further provided with a metal plate-shaped member bonded by welding. When such a metal plate-shaped member is provided, the displacement amount can be reduced by 5% or more as compared with the case where it is not provided. Therefore, the take-out speed can be further increased.

A metal connecting member is welded to two metal column members arranged along a molding machine of a plurality of metal column members, and the two metal column members are formed along the metal connecting member. It is preferable that the reinforcing beam member is welded. In this way, the displacement amount can be reduced by nearly 4% as compared with the case where the reinforcing beam member is not provided.

The molded product take-out mechanism consists of a drawing frame that is attached to a metal top plate at one end and extends in the mold opening / closing direction of the molding machine, and a drawing frame that is movably attached to the drawing frame via a linear guide mechanism and follows the drawing frame.

The structure may include a moving second moving body and a take-out head attached to the second moving pulling body. Of course, a molded product take-out mechanism having another structure can be used.

The two metal column members sandwiching one side opening of the skeleton structure located opposite to the direction in which the drawing frame extends have one side opening located above the metal plate-like member. It is preferable that the first metal side plate that closes the portion is joined by welding.

The two metal column members facing the two metal column members to which the reinforcing beam members are welded have a second metal that closes the lateral opening located below the metal plate-like member. It is preferable that the manufacturing side plates are joined by welding. In this way, the displacement amount can be reduced by 10% or more as compared with the case where the first metal side plate is connected to the frame structure.

Further, a third metal side plate that closes one opening is joined by welding to two metal column members that sandwich one of the side openings of the frame structure located in the direction in which the drawing frame extends. It is preferable that it is. In this way, the displacement amount can be reduced by 40% or more as compared with the case where the second metal side plate is connected to the skeleton structure.

Further, the two metal column members to which the reinforcing beam members are welded together have a fourth metal side plate that closes one side opening formed between the two metal column members. It is preferably bonded by welding. In this way, the displacement amount can be reduced by nearly 5% as compared with the case where the third metal side plate is connected to the frame structure.

The metal column member, the upper metal beam member, the lower metal beam member, the intermediate metal beam member, the reinforcing beam member, the metal plate-shaped member, and the first to fourth metal side plates are iron-based. It is preferably formed of a material. If it is an iron-based material, the strength of the gantry can be maximized.

Further, at least the drawing frame of the molded product taking-out mechanism is preferably made of an iron-based material, but the orthogonal frame is also preferably made of an iron-based material. If these parts are made of an iron-based material, the weight is increased, but the deformation of the molded product taking-out mechanism can be suppressed, and the drawing frame and the orthogonal frame can be suppressed from vibrating.

Further, the drawing frame has a first outer surface extending in the extending direction of the drawing frame and extending in the vertical direction, and a second outer surface continuous with the first outer surface and intersecting with the first outer surface. In the linear guide mechanism, it is preferable that the first outer surface and the second outer surface are configured as installation surfaces on which the guide mechanism components are installed. In this way, the two forces acting between the linear guide mechanism and the drawing frame are directed in directions orthogonal to each other, and deformation of the drawing frame when the first moving body moves can be suppressed. As a result, it contributes to the reduction of the displacement amount.

The guide mechanism component installation wall included in the first moving body facing the first outer surface of the drawing frame and to which a part of the guide mechanism component of the linear guide mechanism is attached is formed of an iron-based plate material. preferable. In this way, the deformation of the moving first moving body can be suppressed and the generation of vibration can be suppressed, and as a result, the displacement amount can be reduced. It goes without saying that the guide mechanism component installation wall may be constructed of an aluminum material if the required strength can be obtained structurally.

An orthogonal frame 11 that moves in the opening / closing direction (Y direction) and moves in the orthogonal direction (X direction) is further provided. Between the drawing frame 9 and the orthogonal frame 11, there is a first moving body 18A that is movably attached via a linear guide mechanism and moves along the drawing frame 9. Then, the orthogonal frame 11 is attached to the first moving body 18A, extends in the horizontal direction orthogonal to the drawing frame 9, and moves in the horizontal direction orthogonal to the driving mechanism 16. The orthogonal frame 11 includes a second moving body 18B that moves along the orthogonal frame 11. An extraction head 14 is attached to the second moving body 18B. A rotating motor 13 is mounted on the second moving body 18B, and the rotation of the rotating motor 13 causes the second moving body 18B to move along the orthogonal frame, and the take-out head 14 is placed between the molds 5. It is inserted and the molded product is taken out from the mold 5. The orthogonal frame 11 moves in the Y direction when the molded product is pulled out from the mold 5 and when the molded product is conveyed to a molded product collection unit (not shown). In the present embodiment, as shown in FIG. 2, the mounting structure 19 for attaching the pull-out frame 9 to the gantry 7 and a part of the pull-out frame 9 are covered with a cover member 40 having an opening 40A. In the present embodiment, the molded product taking-out mechanism 20 is composed of the drawing frame 9, the orthogonal frame 11, the driving mechanism 16, the first moving body 18A, the second moving body 18B, the taking-out head 14, and the like.

The contours of the attached molded product take-out mechanism 20 and the molding machine 3 are shown. The gantry 7 has four iron metal side plates 41-44 attached to the skeleton structure 21 so as to block at least a part of the four side openings 29A, 29C and 29D of the skeleton structure 21 [FIG. 4 (A). ) To (C)], an iron metal top plate 31 joined to the skeleton structure so as to block at least a part of the upper opening 29E of the skeleton structure 21, and at least the lower opening 29F of the skeleton structure 21. An iron metal bottom plate 33 [see FIG. 4 (D)] bonded to the skeleton structure so as to partially block the iron metal connecting member 35 and the iron metal connecting member 35 bonded to the skeleton structure 21 and connected to the molding machine 3. It has 37. The molded product take-out mechanism 20 is attached to the metal top plate 31 via the attachment structure 19.

It is a panel.

The basic frame structure 21 includes four metal column members 23A to 23D, four metal upper beam members 25A to 25D connecting the upper ends of each of the four metal column members 23A to 23D, and four. The four metal lower beam members 27A to 27D connecting the lower ends of the metal column members 23A to 23D of the book are respectively joined by welding joint (joint structure formed by welding). .. Further, the skeleton structure 21, the metal top plate 31, the metal bottom plate 33, and the metal side plates 41 to 44 described later are all realized by welding. Welded joints (joint structures formed by welding) have stronger mechanical strength than bolt-nut joints, screw joints, and inset joints. Therefore, the strength of the skeleton structure 21 can be made higher than that of the conventional pedestal formed by connecting bolts and nuts.

In the present embodiment, the drawing frame 9 of the molded product take-out mechanism 20 is made of an iron-based material, and the orthogonal frame 11 is made of an aluminum material.

The guide sliders 10C and 10D move along the rails 10A and 10B. In this way, the two forces acting between the linear guide mechanism 10 and the drawing frame 9 are directed in directions orthogonal to each other, and the drawing frame 9 is deformed when the first moving body 18A moves. Can be suppressed. As a result, it contributes to the reduction of the displacement amount.

Further, the guide mechanism component installation wall 18Aa included in the first moving body 18A facing the first outer surface 9A of the drawing frame 9 and to which a part of the guide mechanism component of the linear guide mechanism 10 is attached is formed of an aluminum material. However, it is preferably formed of an iron-based plate material. In this way, the deformation of the moving first moving body 18A can be suppressed, and the generation of vibration can be suppressed.

In the present embodiment, in order to further increase the strength of the basic skeleton structure 21, the four upper ends and the four lower ends of the four metal column members 23A to 23D are formed as shown in FIG. 7C. Four metal intermediate beam members 26A to 26D connecting the four metal column members 23A to 23D are joined by welding at a position between them. When these metal intermediate beam members 26A to 26D are joined by welding, the displacement of the reference position of the molded product take-out mechanism 20 when the molded product take-out mechanism 20 operates is larger than that in the case without the metal intermediate beam members 26A to 26D. The amount can be halved. Therefore, the take-out speed can be made faster than before. In the following description, the displacement amount is the displacement of the reference portion R provided at the tip end portion of the drawing frame 9, as shown in the figure showing an example of the simulation result (displacement amount multiplied by 500) in FIG. The quantity. Then, from the position of the reference portion R when the molded product take-out mechanism 20 is not operating, the displacement amount is obtained by simulation to determine how many mm the reference portion R is displaced when the molded product take-out mechanism 20 is operating.
