The advancing / retracting drive cylinder 202 shown in FIG. 10 drives the pair of cooling plates 204 to advance and retreat, thereby moving the cooling block 198 and the pressing member 200 forward and backward with respect to the preform 28.
[0084]
Further, in the handle insert station 52, as shown in FIG. 11, when the handle 50 is inserted, the positioning plate 208 is driven by the positioning cylinder 206 so that the V-shaped engaging portion 210 of the positioning plate 208 is conveyed. The conveying member 36 is positioned by being engaged with 36.
[0085]
An anti-rotation plate 214 slidably supported by the slide rod 212 is provided on the positioning plate 208 so as to be biased toward the engaging portion 210 by a spring 216 and face the engaging portion 210. When the rotation preventing plate 214 is moved away from the conveying member 36 after the positioning plate 208 is released, the conveying member 36 is rotated by the positioning releasing operation of the positioning plate 208 and the position of the handle 50 is shifted. It is preventing.
[0086]
Next, a method of forming a container with a handle using the above-described container forming apparatus with a handle, particularly an operation in the blow molding stage 14 will be described.
[0087]
In the blow molding stage 14, the preform 28 supported by the conveying member 36 in an inverted state is intermittently conveyed by the conveying means 34. The preform 28 passing through the heating device 43 provided in the heating station 42 is heated to a temperature appropriate for blow molding or higher, and then stopped at the handle insert station 52 before being conveyed to the blow molding station 44.
[0088]
In the handle insert station 52, the plurality of handle supply cassettes 78 supported by the cassette support member 112 are sequentially transferred to the cassette standby position b by the rotation of the ascending chain 114 in the cassette supply / conveyance mechanism 108.
[0089]
One handle supply cassette 78 that has reached the cassette supply position b is transferred to the handle supply position a by driving the cassette transfer cylinder 110.
[0090]
One handle supply cassette 78 set at the handle supply position is positioned and the stopper 102 is released by driving the positioning cylinder 130, and the handle 50 in the handle supply cassette 78 can be fed out.
[0091]
In this state, the delivery cylinder 134 is driven, and the handle 50 in the handle supply cassette 78 is delivered to the linear feeder 72 and supplied by the delivery member 132 while maintaining the original alignment state.
[0092]
When the supply of all the handles 50 in one handle supply cassette 78 is completed, the next one handle supply cassette 78 is transferred from the cassette standby position b to the handle supply position a by the cassette transfer cylinder 110.
[0093]
When the new handle supply cassette 78 is transferred to the handle supply position a, the empty handle supply cassette 78 is pushed out to the cassette discharge position c and supported on the discharge guide 140 of the cassette discharge mechanism 84. . Thereafter, the empty handle supply cassette 78 is discharged to the handle discharge port by driving the lowering chain 138.
[0094]
The plurality of grips 50 supplied to the linear feeder 72 are transported to the grip direction changing mechanism 74 in a state in which the respective longitudinal axis directions are aligned parallel to the direction orthogonal to the transport direction, and are stopped at the position of the stopper 152.
[0095]
In the handle direction changing mechanism 74, as shown in FIG. 8, the rotating disk 166 is rotated and the pressing member is rotated with the grip portion 64 of one handle 50 mounted and supported on the handle mounting member 168 of the rotating disk 166. The handle 50 is revolved while 170 pushes the engaging portion 66 of the handle 50.
[0096]
During this revolving movement, the handle 50 is changed in direction so that the ring portion 62 faces downward along the circumferential guide portion 158 so that the central axis of the ring portion 62 is brought into a vertical state by the linear guide portion 160. 90 ° direction. Then, the one grip 50 once stopped by the stopper 162 a at the position of the upper end of the linear guide portion 160 is pushed by the push member 170 by the further rotation of the rotating plate 166, and along the linear guide portion 160. Is lowered. Then, at the standby position at the lower end of the linear guide portion 160, one handle 50 is standby by the stopper 162a.
[0097]
The direction of the handle 50 at this standby position coincides with the direction of the handle receiving recess 340 formed in the blow cavity mold 48 of the blow molding station 44. Therefore, a mechanism for converting the handle 50 into the direction of the handle receiving recess 340 is unnecessary, and the apparatus is simplified.
[0098]
In the handle insert device 76, the holding members 182 and 184 of the holding mechanism 178 are in an open state and stand by at the receiving position of the handle 50, and the handle 50 in the standby position is held by the ring portion 62 by the holding members 182 and 184. First, the gripping portion 64 is held thereafter. As a result, the handle 50 enters the insert standby state above the handle insert station 52.
[0099]
In this state, when the preform 28 held in an inverted state on the transport member 36 is transported to the handle insert position and stopped, the positioning plate 208 and the rotation prevention plate 214 are engaged with the transport member 36 by the positioning cylinder 206 and transported. The member 36 is positioned.
[0100]
Next, the holding members 182 and 184 are lowered to the attachment position e by the elevating cylinder 196, and the ring portion 62 of the handle 50 is inserted into the body portion of the preform 28 and is brought into contact with the flange portion 58 of the preform 28. Placed.
[0101]
When the ring portion 62 of the handle 50 is inserted into the preform 28, the cooling block 198 and the pressing member 200 are advanced to the preform 28 side by the advance / retreat driving cylinder 202, and the container formed by blow molding by the contact of the cooling block 198. The body portion of the preform 28 corresponding to the position where the body portion 38 engages with the engaging portion 66 of the handle 50 is cooled.
[0102]
After the preform 28 is cooled, the cooling block 198 and the pressing member 200 are retracted, the holding members 182 and 184 are opened, and are moved up to the standby position by the lifting cylinder 196 to be in a standby state for holding the next handle 50. . In this case, since the pressing member 200 presses the preform 28 before the cooling block 198 and the pressing member 200 is released after the cooling block 198 is separated from the preform 28, the inclination of the preform 28 due to the contact of the cooling block 198 is prevented. Is done. Further, since the holding members 182 and 184 release the ring part 62 last, the handle 50 does not tilt with respect to the preform 28.
[0103]
Thus, in the handle insert device 76, the holding and raising mechanism 174 only needs to raise and lower the holding members 182 and 184 between the standby position d and the mounting position e, and the operation is simple and can be performed in a short time. The cycle can be improved.
[0104]
Further, since the ring portion 62 of the handle 50 is inserted into the preform body with the conveying member 36 positioned, accurate insertion can be performed, and the preform 28 can be applied to the preform 28 after heating. It will be possible to install without scratching.
[0105]
Furthermore, since the handle 50 is attached to the heated preform 28 at the handle insert station 52, the preform can be heated without the handle, as compared with the case where the preform is heated after the handle is attached. The grip 50 does not get in the way and desired heating can be performed.
[0106]
When the positioning plate 208 and the rotation prevention plate 214 are retracted from the conveying member 36 by the positioning cylinder 206 with the handle 50 attached to the preform 28, the conveying member 36 holding the preform 28 with the handle 50 is removed. It is ready to be transported. In this case, since the rotation prevention plate 214 is separated from the conveying member 36 after the positioning plate 208, it is possible to prevent the conveying member 36 from rotating when the positioning of the conveying member 36 by the positioning plate 208 is released.
[0107]
Then, with the handle 50 attached to the heated preform 28, the conveying member 34 conveys the conveying member 36 to the blow molding station 44 in the direction A in FIG. The container 38 integrated with the handle 50 is formed by blow molding with high-pressure air.
[0108]
In this case, when the preform 28 with the handle 50 is stored in the blow cavity mold 48, the position of the handle 50 is adjusted to the direction of the handle receiving recess 340 at the handle insert station 52. A means for aligning 50 and the handle receiving recess 340 is not necessary, and a simple configuration can be achieved.
[0109]
Further, at the time of blow molding, the body portion of the preform 28 corresponding to the body portion of the container 38 engaged with the handle engaging portion 66 at the handle insert station 52 is cooled by the cooling block 198. The body portion of the container 38 that engages with the joint portion 66 can be made thicker, and the attachment strength of the handle can be improved.
