, A molded article receiving unit 20 can be additionally provided. Here, when the molded article receiving unit 20 is added, an opening for communicating the air passage 23 a provided in the bottom 23 of the casing 22 with the air supply / discharge passage 3 a of the support frame 3 is required. Based on this,
Such an opening is formed in the support frame 3 in advance. The opening is closed by a blind plate or the like (not shown) until the molded article receiving unit 20 is added.

As shown in FIG. 6, the air supply / discharge passage 3a of the support frame 3 is connected to an air supply / exhaust device (not shown) via a switching valve 33 and an air pipe 34 composed of a flexible pipe and the like. When the molded product P is inserted into the molded product receiving sleeve 21 and held, the switching valve 33 is switched to the exhaust side, and the molded product receiving unit 20 (the molded product receiving sleeve 21) is connected via the air supply / discharge passage 3a. Evacuate the inside. When the molded product P held by the molded product receiving sleeve 21 is to be released, the switching valve 33 is switched to the air supply side, and each molded product receiving unit 20 (the molded product receiving sleeve 2) is released.
A positive pressure air is supplied into 1).

Further, as shown in FIG.
The molded article receiving unit 20r (FIG. 6)
, The article receiving unit 20 located on the rightmost side
Is supplied with a coolant from a coolant supply device (not shown) via a coolant supply pipe 35. That is, the coolant supply pipe 35 is connected to the coolant circulation space 2 of the molded article receiving unit 20r.
7 (see FIGS. 4 and 5). A coolant outlet 29 communicating with the coolant flow space 27 is provided at a coolant inlet 28 of the article receiving unit 20 (on the left side) adjacent to the article receiving unit 20r.
And a cooling liquid flow pipe 36. In this way, the coolant flow outlet 29 and the coolant flow inlet 28 of the adjacent molded article receiving units 20 are connected by the coolant flow pipe 36. The cooling liquid outlet 29 of the molded article receiving unit 201 fixed to the end side of the support frame 3.
Is connected to a coolant discharge pipe 37.

The cooling liquid supplied to the molded article receiving unit 20r through the cooling liquid supply pipe 35 circulates sequentially in the cooling liquid circulation space 27 of each molded article receiving unit 20, and the cooling liquid supplied to the molded article receiving unit 20l. The cooling liquid is returned to a cooling liquid supply device (not shown) via a cooling liquid discharge pipe 37 connected to the outlet 29, and is cooled again. Thereby, since the low-temperature cooling liquid is always supplied to each molded article receiving unit 20, each molded article P held by each molded article receiving unit 20 can be efficiently cooled.

Hereinafter, a procedure for processing a molded article by the above-described molded article unloading apparatus 1 will be described with reference to FIGS. 1, 2, and 7. FIG.

When the molded products P are molded in a state of being arranged in a predetermined arrangement pattern by the injection molding machine 50, each molded product P is maintained at a temperature at which the shape formed by the molds 54 and 55 can be maintained (for example, (Up to about 110 ° C. to 120 ° C. or less) in the injection molding machine 50. Injection molding machine 5
When the cooling of each molded product P within 0 is completed, the mold opening / closing cylinder 57 is driven. Thereby, the movable platen 53 is separated from the fixed platen 52 by the distance E (see FIG. 1), and the molds 54 and 55 of the injection molding machine 50 are opened. As described above, at the stage where the molding cycle 0 (first molding by the injection molding machine 50) in FIG. 7 is completed, the molded product removal device 1 is operated.

At this time, the molded article holding device 2 is positioned above the molded article cooling section 14 (the position shown by a two-dot chain line in FIGS. 1 and 2). Further, each molded article receiving unit 20 is configured such that each molded article receiving sleeve 21 is
(See FIG. 1) by the rotation drive mechanism 6 so as to face the mold clamping direction (horizontal direction). From this state, the holding device moving mechanism 4 injects the molded product holding device 2 along a horizontal direction (extending direction of the rotation shaft 8 of the rotation drive mechanism 6) orthogonal to the mold clamping direction of the dies 54 and 55. It is moved with respect to the molding machine 50.

Specifically, the timing belt 12 is circulated by a predetermined amount by driving the servo motor 11 of the horizontal transfer mechanism 10 included in the holding device moving mechanism 4, and the vertical moving mechanism fixed to the timing belt 12 is driven. The molded product holding device 2 is moved via the reference numeral 5. As a result, the molded article holding device 2 moves the distance G from above the molded article cooling unit 14.
(See FIG. 1) and is located between the fixed mold 54 and the movable mold 55. The molded article holding device 2 is a mold 5
4 and 55, each molded product receiving sleeve 21 provided in each molded product receiving unit 20
5 and extends in parallel with the axis of each of the molded products P aligned with each other and faces each of the molded products P aligned with a predetermined arrangement pattern.

When each molded product receiving sleeve 21 faces each molded product P, a molded product protruding device (not shown) provided in the molds 54 and 55 is operated, and each molded product P is moved to the molded product receiving unit 20. Stick out. As a result, each molded product P aligned on the movable mold 55 is gradually inserted into each molded product receiving sleeve 21 from its tip. As a result, each molded product P is accommodated inside each molded product receiving sleeve 21, and the tip of the molded product P comes into contact with the receiving plug 30.

When each molded product P is accommodated in each molded product receiving sleeve 21, the switching valve 3 connected to the air pipe 34 at the same time
3 (see FIG. 6) is switched to the exhaust side. Thereby, the inside of the molded article receiving sleeve 21 is evacuated via the air hole 31, the air passage 23a of the receiving plug 30 and the air supply / discharge path 3a inside the support frame 3, and the molded article P is attracted to the receiving plug 30. . Therefore, the molded product P is sucked and held inside the molded product receiving sleeve 21.

Then, the servo motor 11 of the horizontal transfer mechanism 10 is driven, and the molded article holding device 2
And the movable mold 55 slidably moves to above the molded article cooling unit 14. A cooling water circulation space 27 created between the molded product receiving sleeve 21 of the molded product receiving unit 20 holding the molded product P and the casing 22 (the outer cover 24) is cooled through a cooling water inlet 28. Liquid is constantly being introduced. Therefore, while moving the molded article holding device 2 to above the molded article cooling unit 14, each molded article P is actively cooled by the coolant flowing through the cooling water circulation space 27.

Here, since the coolant circulation space 27 of each molded article receiving unit 20 has a relatively large volume, a large amount of coolant flows along the outer peripheral surface of each molded article receiving sleeve 21. Further, the molded article receiving units 20 adjacent to each other are provided with a coolant outlet 29 and a coolant inlet 28.
Is connected via a coolant flow pipe 36 which communicates with the cooling water, so that the low-temperature coolant circulates in the coolant flow space 27 (see FIGS. 4 and 4) of each molded article receiving unit 20. Therefore, all the molded products P held by the molded product holding device 2 are efficiently cooled.

As the cooling liquid supplied to the cooling liquid circulation space 27, cold water of about 10 ° C. is used. As a result, the molded product P held in each molded product receiving sleeve 21 is rapidly cooled, and the temperature of the molded product P becomes the highest at the time of removal when mold clamping is started in the molding cycle 1 shown in FIG. About 110
From 120C to about 90C. in this way,
The molded article P is taken out at a stage where the molded article P is cooled to about 110 ° C. to 120 ° C. in the injection molding machine 50, and cooled to about 90 ° C. by the molded article holding device 2, whereby the injection molding machine 5
0 production efficiency can be significantly improved.

That is, conventionally, a temperature at which the molded article P is not deformed in the mold is about 100 ° C. or less (preferably 70 ° C.).
After cooling the molded article P to the following), the injection molding machine 50
The molded product P was taken out from the company. However, PET
When molding a thick product such as a bottle, a considerable time is required to cool the molded product P to about 100 ° C. or less in the molds 54 and 55. Efficiency was reduced. On the other hand, the time required to cool the molded article P such as a PET bottle to about 110 ° C. to about 120 ° C. is relatively short even in the mold. Therefore, at this stage (below about 110 ° C to 120 ° C)
If the molded product P is taken out of the injection molding machine 50, the molding cycle of the injection molding machine 50 can be shortened.

When the molded article P is cooled, the molded article P
Is slightly shrunk in the radial direction, and a gap is formed between the outer peripheral surface of the molded product P and the inner peripheral surface of the molded product receiving sleeve 21. In the case of the molded product removal device 1, The distal end portion is attracted to the receiving plug 30 in the molded product receiving sleeve 21. Therefore, during the conveyance, the molded article receiving sleeve 21
There is no danger that the molded product P will fall out of the mold.

The molded product holding device 2 is provided with a holding device moving mechanism 4.
When it is moved by the (horizontal transfer mechanism 10) to above the molded article cooling section 14 (the position shown by the two-dot chain line in FIG. 2), the rotary actuator 7 of the rotary drive mechanism 6 is operated. The molded article holding device 2 fixed to the rotating shaft 8 of the rotary actuator 7 is rotated by 90 °, and each molded article receiving unit 20 is integrally directed vertically downward. At this time, in the molded article cooling unit 14, the cooling unit transport mechanism 17 is operated, and the plate 15 included in the molded article cooling unit 15 is moved.
The plate 151 among 1, 152, and 153 is located directly below the molded article holding device 2. As a result, each molded product P held by each molded product receiving sleeve 21 is transferred to each molded product receiving member 16 disposed on the plate 151.
Opposes. In this state, the vertical moving mechanism 5 is operated, and the molded article holding device 2 moves vertically downward by a distance L (see FIG. 2).
Just move. Thereby, each molded product P is inserted into each molded product receiving member 16 of the plate 151 at a time.

When the molded product P is inserted into the molded product receiving member 16 at a time, the switching valve 33 of the molded product holding device 2 is switched to the air supply side. As a result, positive pressure air is supplied into each molded product receiving sleeve 21, so that the molded product P
Is released from the receiving plug 30. The molded product P is cooled in the molded product receiving sleeve 21 and slightly shrinks in the radial direction. Therefore, since a gap is formed between the outer peripheral surface of the molded product P and the inner peripheral surface of the molded product receiving sleeve 21, each molded product P naturally falls from each molded product receiving sleeve 21 and receives each molded product. It is delivered to the member 16. Each molded product P received by the molded product cooling unit 15 is supplied to the air outlet 161 of each molded product receiving member 16.
a, It is sufficiently cooled to a desired temperature (about 50 ° C. or less) by cooling air blown out from the through hole 162a.

Here, since the molded article cooling unit 15 uses air as the refrigerant, the temperature difference between the molded article P and the refrigerant is somewhat small. Therefore, each molded product P is about 50
In order to cool to a temperature of not more than ° C, several times (in this case, about three times) the molding cycle in the injection molding machine 50 is required. Based on this, in the molded product removal apparatus 1, after the molded product P manufactured in the molding cycle 0 is taken out from the injection molding machine 50, until the next molding cycle 1 (see FIG. 7) is completed. , Cooling unit transport mechanism 17
Is operated to move the molded article cooling unit 15. That is, the plate 151 holding and cooling the molded product P in each molded product receiving member 16 is retracted from below the molded product holding device 2 (horizontal transfer mechanism 10), and formed by each molded product receiving member 16. The plate 152 on which the article P has not yet been received is located below the article holding device 2 (horizontal transfer mechanism 10).

As a result, each molded product P held by each molded product receiving member 16 of the plate 151 is sufficiently cooled until the temperature becomes approximately 50 ° C. or less, while the molded product P is not yet received on the plate 152. Each molded article receiving member 16
Of the molded product P. Therefore, as shown in FIG. 7, since there is no wasteful waiting time between the molding cycles in the injection molding machine 50, the production efficiency of the injection molding machine 50 can be improved.

As shown in FIG. 7, when the molding cycle 1 of the injection molding machine 50 is completed, the molded product P is again taken out of the injection molding machine 50 by the molded product holding device 2 and each molded product received on the plate 152 is received. The molded product P is delivered to the member 16. Similarly, when the molding cycle 2 of the injection molding machine 50 is completed, the molded product P is taken out of the injection molding machine 50 by the molded product holding device 2, and the molded product P is transferred to each molded product receiving member 16 on the plate 153. Handed over.

As described above, the time required for cooling the molded article P molded by the injection molding machine 50 to about 50 ° C. or less by the molded article cooling unit 15 is about the same as the molding cycle of the injection molding machine 50. It has tripled. Therefore, between the start and the completion of the molding cycle 3 (see FIG. 7) of the injection molding machine 50, the cooling unit transport mechanism 17 is operated, and the plate 151 of the molded product cooling unit 15 is moved to the molded product holding device 2 (Horizontal transfer mechanism 10).

When the cooling of each molded product P on the plate 151 is completed, the molded product holding device 2 located above the cooling unit transport mechanism 17 is moved by the vertical moving mechanism 5 to the molded product cooling unit 15. Plate 15
1 and each molded product P is inserted into each molded product receiving sleeve 21. Then, the switching valve 33 is switched to the exhaust side, and each molded product P is sucked and held in each molded product receiving sleeve 21. The molded product holding device 2 that has received the molded product P is raised by the vertical movement mechanism 5. As a result, the molded article P is taken out from each molded article receiving member 16 disposed on the plate 151 of the molded article cooling unit 15 and is supplied to each molded article receiving member 16 of the plate 151 in the next molding cycle 4. The molded article P can be delivered.

The molded article holding device 2 having received the molded article P from each molded article receiving member 16 of the plate 151 is moved above the molded article unloading section 18 by the horizontal transfer mechanism 10 (FIGS. 1 and 2).
At the position indicated by the three-dot chain line). The molded article holding device 2 includes a vertical movement mechanism 5.
As a result, it is lowered with respect to the molded article discharge section 18. At this stage, the switching valve 33 is switched to the air supply side, and each molded product P is transferred from each molded product receiving sleeve 21 to the molded product discharge portion 18.
As it falls inside a bulk carrier. In this way, the molded article P is carried out from the molded article cooling section 14 to the molded article carry-out section 18. Molded product P to molded product unloading section 18
Is carried out sequentially at the stage when the cooling of the molded products P on the plates 151, 152, 153 is completed, and when all the molded products P formed by the injection molding machine 50 are conveyed to the molded product discharge section 18, The processing by the molded product removal device 1 ends.
