[Function] Since the present invention has the above-mentioned configuration, in particular, since the take-out arm does not move sideways, a) the structure of the take-out portion can be made sturdy, ignoring its weight.

b) Since the take-out arm can be operated at high speed, the take-out time can be shortened. C) The take-out arm has less vibration and the operating accuracy is improved, so it is not only used for taking out molded products.

It can also be used as an insert machine for inserting into metal molds, etc. d) The cycle time can be significantly shortened compared to conventional take-out machines that operate the take-out arm or the entire process.

In other words, the try cycle time of a take-out machine for a 150-ton class molding machine is usually limited to about IO seconds, and if it operates faster than that, the shock and vibration of each operation will increase, the take-out accuracy will decrease, and the machine will In contrast, in the case of the present invention, the product can be operated in 5 seconds or less because the product is transferred in the middle, and the molded product is transported using a transport pallet. Then, a) It is lightweight and can operate at high speed because it only transports molded products. b) There is no need to make the frame, guide, etc. for 482 transport more sturdy, which reduces costs. C) It is possible to combine molded products on a conveying pallet, change their positions, etc. In other words, these operations were conventionally performed by installing a separate device after taking them out, but according to the present invention, they can be performed in total. It brings about benefits such as cost reduction and required space reduction.

The method for handling molded products at the end of the transport pallet is a) If there is no risk of damage, such as molded products or miscellaneous cargo, the pallet is turned over 18 (1') and handed to a chute, etc.; b) Next. If the equipment in the process requires a pick-up, a device that moves up and down is installed separately at the end of the traveling frame, and the pick-up is handed over. This is optional, as necessary.

(Example) The present invention will now be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a plastic molding machine, and 11 is a schematic diagram of a mold portion. This mold part 1 is opened by a mold opening operation, and the molded product 12 is taken out from above by an automatic take-out device 20, which will be described later.

The automatic take-out device 20 includes a base 21 and a molded product take-out means 30 attached to the base 21. A traverse 22 extending horizontally from the base 21. It is constituted by a pallet 40 that runs horizontally along this traverse 22, and a molded product transfer means 50 that is placed at the end of the traverse 22.

The means 30 for taking out the molded product is fixed to the molding machine and does not move sideways, so it is structurally strong, and the minimum basic operations required are: ■ Ascending/lowering, ■ Forward/backwards, ■ Chuck opening/
Closed. Of course, in addition to such basic movements, rotation and slight lateral movement may also be performed.

Traverse 22 functions as a guide and drive for horizontal linear reciprocating movement of pallet 40. The pallet 40 is supported by the traverse 22 and has a horizontal portion 41 on which molded products are placed.

The stroke of the pallet 40 is from the lower surface position of the molded product take-out means 30 to the lower surface position of the molded product transfer means 50.

The basic function of the pallet 40 is to transport molded products by being supported by the traverse 22 and reciprocating between the molded product take-out means 30 and the molded product transfer means 50 described later. In order to prevent misalignment during the process, it is preferable to provide a guide with unevenness for maintaining the posture.

In addition, instead of a simple guide using unevenness, for example, a vacuum suction cup or a mechanical chuck may be arranged on the pallet 40.
It is also preferable to have a structure in which the attitude, position, direction, height, etc. of the molded product can be actively changed during transportation.

Furthermore, if an openable/closable shutter is provided on the horizontal portion 41 of the pallet 40, it is possible to remove the roughness of the molded product.

If the assembly robot is equipped with a pallet 40 or an operating arm, rather than just a conveying means, it is also possible to assemble different types of molded products taken out from the molding machine while conveying the molded products to the transfer means 50. It is. Such embodiments also include those in which the molded product is not received by a single molding machine but by a plurality of molding machines.

Further, there is also an embodiment in which the pallet 40 is temporarily stopped during transportation, the receiver picks up the molded products assembled by another assembly device, and the receiver transfers the molded products together with the picked up molded products from the molding machine to the transfer means 50. Included in the present invention.

The molded product transfer means 50 is taken out from the mold part 11 of the molding machine 10 by the take-out means 30 and placed on the pallet 40.
A device for picking up the molded product 12 placed on the horizontal portion 41 of the machine and transferring it to an assembly line (not shown), which basically operates in the same way as the take-out means 30.
Of course, there are differences depending on the type of next process.

The above description has mainly focused on the automatic take-out device for molded products, or it is clear that it can be used as an automatic insertion device for metal, etc. by performing the operation completely opposite to the above. That is, the pallet 40 carries out the N transport of metal, etc., and the molded product take-out means 30 serves as a means for inserting metal, etc.

Moreover, the above-mentioned molded product take-out means 30 may also serve as a means for inserting metal etc. into Venus (effects of the invention) According to the present invention, the time required for one cycle of the molded product take-out means is shortened to a large width, and one cycle is completed by ■lowering, ■forwarding, ■chuck closing, ■taking out, and ■raising. Therefore, the waiting time of the molding machine in the conventional equipment is 3
~6 seconds is almost eliminated.

Furthermore, the time required to insert the metal into the mold is greatly reduced, contributing to improved work efficiency.
