JP 2002-326258 A

  By the way, the molded product take-out machine 50 described in the above-mentioned Patent Document 1 is intended only to take out a molded product (work) from the mold device 53, convey it outside the molding machine 52, and release it. It does not have an object for conveying the mold device 53 and a configuration necessary to achieve the object. Therefore, in a general molding factory, after the mold apparatus 53 is transported to the vicinity of the molding machine 52 by a transporting means such as a hand-drawn cart or a forklift, a ceiling-installed hoist such as a forklift or a hoist / crane is moved up and down. It is attached to the molding machine 52 by an operator using a transportation device for attaching and detaching a mold device such as a floor surface traveling transportation device having a possible table or a floor surface stationary transportation device such as a roller conveyor, Even when the mold apparatus 53 is detached from the molding machine 52, it is removed from the molding machine 52 by an operator using the conveying means for attaching and detaching the mold apparatus and carried out in the vicinity of the molding machine 52.

  In the molded product take-out machine 50 described in the above-mentioned Patent Document 1, that is, the transport device, a transport means for attaching and detaching the production head portion is required separately, and the equipment cost increases accordingly. In addition, although accurate positioning is required for mounting the production head unit, it is difficult to accurately set the mounting position with the transporting means for attaching / detaching the production head unit. For this reason, the installation work time of the production head portion becomes long, making the initial setup work and the setup change work continuously performed later complicated, and the workability thereof is remarkably deteriorated.

  The present invention solves such a problem, and the object of the present invention is not to depend on the transport means for attaching / detaching the production head part, and therefore, the transport means for attaching / detaching the production head part is unnecessary. In addition to reducing equipment costs, the installation position of the production head can be easily set with high accuracy, shortening the installation work time, simplifying initial setup work and setup change work, etc. An object of the present invention is to provide an improved transport device.

  In order to achieve the above object, a transport apparatus according to the present invention is a transport apparatus for taking out and transporting a work produced by a production head section mounted on a production apparatus from the production head section. The production head unit can be carried into the production apparatus from the outside of the production apparatus, and the production head unit can be carried out of the production apparatus.

  According to this, since the conveying device can carry the production head unit into the production device from the outside of the production device and can carry the production head unit out of the production device and take it out, No transportation means is required.

  According to the present invention, the production device comprises a molding machine, the production head comprises a molding die device, and the workpiece comprises a molded product, a molded product and a spool or a molded product and a spool runner, and the conveyance The apparatus comprises: a workpiece take-out head that grips and removes the workpiece from the molding mold apparatus; and a mold apparatus suspension means that suspends and lifts the molding mold apparatus, and the mold apparatus suspension It is characterized in that it is constituted by a molded product take-out machine capable of operating the molding die device suspended by the means to approach and separate from the molding die device attaching / detaching position of the molding machine.

  According to this, the mold apparatus for molding conveyed in the vicinity of the molding machine is suspended by the mold apparatus suspension means provided in the molded article take-out machine, and in this state, the molded article extractor is driven. Then, after the molding die device is brought close to the molding die device attaching / detaching position of the molding machine, the operator moves the molding die device from the die device holding means to the molding die device attaching / detaching position. Thus, the molding die apparatus can be mounted on the molding machine. Also, after the molding device is mounted on the molding machine, the molded product take-out machine is driven to bring the molding device suspension means close to the molding device, and then the molding tool is operated by the operator. After the apparatus is transferred from the molding die apparatus attaching / detaching position to the mold apparatus lifting means and suspended, the molding apparatus is moved by driving the molded product take-out machine. It can be separated from the apparatus attachment / detachment position and taken out of the molding machine. Furthermore, similar to the drive system of the molded product take-out head in the existing molded product take-out machine, the rotation of the servo motor (drive source) that is numerically controlled by a servo driver (drive source control means), encoder (position detector), etc. By driving the mold apparatus suspending means, the raising / lowering amount of the mold apparatus by the mold apparatus suspending means and the movement amount of the mold apparatus suspending means by the molded product take-out machine can be set with high accuracy. Therefore, it is possible to easily set the molding die device with respect to the molding die device attaching / detaching position of the molding machine with high accuracy. Therefore, it is possible to shorten the time for attaching the molding die device, simplify the initial setup work and the setup change work, and improve the workability thereof.

  Further, according to the present invention, the rotational force of each of the drive source on the molded product take-out machine side and the drive source on the mold device lifting means side is set to the load applied to each of the molded product take-out machine and the mold device lifting means. It is desirable that the output be changed automatically by the continuously variable transmission according to the size. According to this, since a heavy load is applied to the mold device suspension means and the molded product take-out machine when the molding die device is attached and detached, the drive source and the molded product take-out machine on the mold device suspension means side are loaded. It is possible to drive the mold device suspension means and the molded product take-out machine by converting the rated rotational force of each of the drive sources on the side into output that is greater than that of the continuously variable transmission. This eliminates the need for an expensive drive source dedicated to heavy loads, thereby reducing the initial cost.

  According to the present invention, since the transportation means for attaching / detaching the production head part which has been conventionally required is not required, the equipment cost can be reduced accordingly. In addition, since the installation position of the production head can be easily set with high precision, the time required for mounting the molding die device can be shortened, and initial setup work and setup change work can be simplified. Can be improved.

Next, the suspension hook 13a of the mold apparatus suspension means 13 is locked to the eyebolt of the intermediate mold 32 by a combination of the first, sixth and seventh operations, and the operator presses the intermediate mold 32 here. After transferring from the intermediate mold holding rod 1C to the suspension hook 13a, the mold device suspension means 13 is used to suspend the intermediate mold 32 by a combination of the first, sixth and seventh operations, and the molding machine. Transport to near M and release. Further, the suspension hook 13a of the mold apparatus suspension means 13 is locked to the eyebolt of the fixed mold 30 by combining the first, sixth and seventh operations, and the fixed mold 30 is fixed by the operator here. After transfer from the platen 1 to the suspension hook 13a, the fixed mold 30 is suspended by the mold apparatus suspension means 13 by the combination of the first, sixth and seventh operations until the vicinity of the molding machine M. It can be easily realized by transporting and releasing. That is, it is possible to simplify the setup change for removing the molding die device 33 from the molding machine M for replacement, and to improve the workability. The procedure for mounting another molding die device on the molding machine M instead of the molding die device 33 removed from the molding machine M is the same as the procedure described above.

  When the molding die device 33 is attached to and detached from the molding machine M, heavy loads are applied to the die device lifting means 13 and the transverse frame 3 and the drawing frame 4 of the molded product take-out machine 2, so that the seventh servo The rated rotational force of the motor 27 is converted into a greater rotational force for the continuously variable transmission 6 </ b> B, the suspension hook 13 a is moved up and down, and the rated rotational force of the first servomotor 8 is increased to the continuously variable transmission 6. The output conversion is performed to move the extraction frame 4 forward and backward in the direction of the arrow X, and the rated rotational force of the sixth servomotor 24 is converted to an output greater than that of the continuously variable transmission 6A. The seventh servo motor 27, the first servo motor 8, and the sixth servo motor 24 are not constituted by a high-power and expensive servo motor dedicated to heavy loads because the advancing and retreating in the arrow Y direction is performed. It may be. That is, since an expensive drive source dedicated to heavy loads is not required, the initial cost can be suppressed.

  In the above embodiment, the molding product take-out machine 2 provided with the molded product take-out head 5a and the runner take-out head 5b has been described as taking out a workpiece composed of the molded product and the spool runner. If the apparatus 33 is composed of the fixed mold 30 and the movable mold 31, and therefore the resin molding machine M is configured to mold a workpiece including a molded product and a spool integrated with the molded product, only the molded product take-out head 5a is used. Therefore, the runner take-out head 5b becomes unnecessary. Moreover, the number of the suspension hooks 13a of the mold apparatus suspension means 13 may be two.
