By moving the piston rod 60a back and forth, the main body 61 of the device can be moved forward and backward in a straight line on one side of the vulcanizer in parallel to the take-out direction indicated by the arrow P. Hole 6
5, an arm shaft 67 with a pair of take-out arms 66, 66 arranged parallel to each other is inserted and supported so as to be able to rise and fall and rotate freely. A sliding shaft 68 that can be raised and lowered along with the shaft 67 is also inserted into the elongated hole 65 and supported, and the sliding shaft 68 is provided with both a take-out arm stopper 69 and an arm tilting cylinder 70. Piston rod 7 of the cylinder 70
The rack 71 attached to the arm shaft 67
By meshing a driving gear 72 attached to a part of the piston rod, the cylinder 70 is operated, the piston rod 70a moves forward and backward, and the rack 71 moves along with it.
By the forward and reverse rotation of the drive gear 72, the take-out arms 66, 66 supported by the arm shaft 67 can be horizontally and tilted freely with the rotation of the shaft 67. A group of 73 sliding rollers are arranged in a row so as to freely rotate. Furthermore, in order to raise and lower the arm shaft 67 and the accompanying sliding shaft 68 within the elongated elevating guide hole 65, a lift lever link 74 having a substantially L shape is attached to the arm shaft 67 in a protruding manner. The other end of a lift lever 76, which has one end pivoted to the device body 61 by a pivot 75, is connected to one end of the lift lever 74 by a pivot 77, and a lift lever 76 is installed in the middle of the lift lever 76 using the device body 61 as well. By connecting the cylinder 78 and the piston rod 78a, the lift lever link 74 is raised and lowered through the operation of the cylinder 78, the forward and backward movement of the piston rod 78a, and the forward and reverse rotation of the lift lever 76 using the pivot shaft 75 as a fulcrum. , guide slot 6
Thus, the arm shaft 67 and the sliding shaft 68 can be moved up and down along the axis 5. Further, an elevating bracket 81 is inserted into a guide elongated hole 8 provided in a bracket 79 provided upright at the front end of the device main body 61, and a piston rod 82a of an elevating cylinder 82 provided on the bracket 79 side.
The base of a holding arm 84 of the tire Y is fixed to the lifting bracket 81 via a support part 83.
is in the form of a substantially U-shaped arm extending over the pair of take-out arms 66, 66 mentioned above, and has an engagement positional relationship with respect to the tire Y as shown in FIG.

In such a take-out device, the take-out arm shaft 6
A guide roller 51 is rotatably attached to one axial end (opposite side of the device main body 61) of 7, and the guide roller 51 is installed horizontally using a base side plate 52 on the vulcanizer side. At the same time, a mounting bracket 85 is provided upright on a part of the guide rail 53, and the guide cam member 37 is provided on the bracket 85 above the guide rail 53 as shown in the figure. At this time, the cam member 37 includes both a band-shaped cam main plate 38 having an inclined sliding surface 39 at a required angle, and an auxiliary cam plate 40 elastically supported on the upper end of the cam main plate 38 by a pivot 43, a spring 44, and a stopper 45. At this time, the auxiliary cam plate 40 is connected to the guide roller 51.
It also serves as a stopper for the arm shaft 67 via the support surface of the guide roller 51 and the sliding slope surface 39.
In the illustrated example, reference numeral 86 indicates a mounting block for fixing the guide rail 53 to the side of the base side plate 52.

The removal of the vulcanized tire Y by the device main body 61 involves the completion of tire vulcanization in the tire vulcanizer, the opening and evacuation of the movable upper mold, and the removal of the bladder from the inner surface of the tire by the vulcanizer central mechanism, as described above. At the same time, the device main body 61 at the solid line position in FIGS. The ejecting arms 66, 66,
As shown by the chain line in FIG. 6, the tire holding arm 84 also enters in a horizontal state toward the vulcanizer center line XX along with the guidance of the guide rollers 51 and guide rails 53, and then the lifting cylinder 78 is activated. Lift lever 76 by pushing out piston rod 78a
The take-out arms 66, 66 are rotated upward about the pivot shaft 75, and the lift lever link 74 is raised along with the lift lever link 74.
It rises straight along the elongated elevating guide hole 65 to a position where it can avoid the vulcanizer bladder,
Further, the tire holding arm 84 is also raised through the lifting of the lifting bracket 81 by the operation of the cylinder 82, and the vulcanized tire Y is supported and held, and the change in this raised position is shown by the chain line in Figure 6. As shown, the operation of the cylinder 70 on the sliding shaft 68, the lowering of the piston rod 70a, and the accompanying lowering of the rack 71 thereby cause the drive gear 7 to move.
Due to the meshing rotation of the two, the take-out arms 66, 66 take an inclined position as shown in the figure as the arm shaft 67 rotates, and at this time, the tire Y received over the arms 66, 66 is moved to the advancing/retreating cylinder 60. Through the retreat of the device main body 61, the free state of the cylinder 78, the lowering of the arm shaft 67 by the rolling guide on the inclined sliding surface 39 of the guide cam member 37 of the guide roller 51, and the subsequent guidance by the guide rail 53, The material can be taken out smoothly without any impact on the removal side.

According to this take-out device, the tire Y is reliably moved into the vulcanizer by the tire support member consisting of the take-out arms 13 to 66, which enter the tire vulcanizer center position in a horizontal position and are capable of rising and tilting. By using the guide cam member 37 that regulates this tilted backward posture when receiving the tire from the side and taking it out as it moves backward at an incline, it is possible to take it out very smoothly and without giving any impact or deformation to the tire. It has excellent features in terms of what it can provide.

(Problems to be Solved by the Invention) As is well known, the temperature of the tire taken out after vulcanization molding in a tire vulcanizer is still high and it is quite soft, so when handling it, it is necessary to handle it as softly as possible. This also applies to the above-mentioned take-out device, and in such a take-out device, the vulcanized tire held on the take-out member is not distorted or deformed, and It is important to securely and safely hold the tire so that it does not escape or move from above the removal member. In the take-out device illustrated in FIGS. 5 and 6, the vulcanized tire Y is supported on a pair of take-out arms 66, 66 that are provided in parallel and are horizontally and freely tiltable, and the upper surface of the tire Y is Although a means of holding the holding arm 84 is used, this method has the following problems. In general, most tire vulcanizers are twin-type, with two left and right mold sets installed on the vulcanizer base frame, and the recent trend has been to diversify tire sizes.
With the increase in flattening, the left and right mold sets are often changed in size, and the difference in size between the left and right mold sets causes a difference in tire width. In such a case, if the holding arms of both mold sets are operated simultaneously on the left and right sides, the smaller tire width may not be able to be held, and in order to hold the smaller size side, it may be necessary to over-press the arms on the larger size side. This may cause deformation of the tire. Furthermore, the holding arm structure that supports the tire from above requires a considerable holding force in order to prevent the tire from tilting or moving blindly, which has the drawback of easily causing tire deformation. The purpose of the left and right take-out devices in a twin-type vulcanizer is to take out left and right tires at the same time.
In order to hold the left and right tires, a certain holding force is commonly set for 4, but due to production reasons, there are cases where only one mold assembly is operated for one-sided vulcanization. In this case, a stronger force is applied to one tire, pushing the tire excessively and making the tire support state unstable. Further, the following problem arises in that the take-out arms 66, 66 are pivoted in the middle so that they can be horizontally tilted, and are operated by the guide cam 37. That is, in FIG. 6, the take-out arms 96, 66, which are in the retracted position shown by solid lines, are advanced to the forward positions shown by chain lines, support the bottom surface of the vulcanized tire on the vulcanizer side, and from this position vertically When raising the bladder to avoid the bladder, the side with the guide roller 51 at one end does not have a support or guide structure for vertical rise, and the shaft ends of the arm shaft 67 are free on both the left and right sides, so bearings, etc. may wear out. Due to backlash caused in the front-back direction due to such factors, a phase difference occurs, and the guide roller 51 cannot smoothly ride on the auxiliary cam plate 40 at the front end of the guide cam 37, which tends to cause the arm shaft to fall. Even if this is not the case, there will be a phase difference in the vertical direction between both ends of the free arm shaft 67 on both the left and right sides, and the arm shaft 67 will also tend to tilt, making it difficult to smoothly transfer onto the auxiliary cam plate 40. This problem is further exacerbated by the fact that when one side is vulcanized, the tire is placed on only one arm, so an uneven load acts on the arm shaft 67, which may cause it to tilt. This lacks consistency in behavior, and reliability and cycle time tend to become unstable, which is why improvements are still needed.

(Means for Solving the Problems) The present invention provides the above-mentioned horizontally tiltable take-out arm 6.
In order to solve the problems with the take-out device using the holding arm 84 and the guide cam 37, the holding arm can hold the top surface of the tire with extremely light force, and the guide structure of the take-out arm 66 is improved. The machine is designed to be able to move forward and backward towards the center of the tire vulcanizer, and at the center position, it moves upward and towards the tire removal side. a guide cam comprising: a tire take-out arm that is tiltable; and a guide cam that is disposed between the take-out arm in the inclined position and the take-out point, and has an inclined sliding surface that slides and guides the take-out arm in the inclined position toward the take-out point. A tire holding arm is provided in contact with and supported on the upper surface of the tire on the take-out arm so that it can be raised and lowered along with and independently of the take-out arm, and the tire on the take-out arm is locked at the rear end of the tire holding arm. A tire locking stopper is adjustable and attached to the guide cam side, and a vertical guide surface that guides the take-out arm when the take-out arm is raised at the center position, and a tire-locking stopper that slides on the inclined sliding surface of the guide cam. A guide plate is provided with an inclined sliding guide surface that guides the take-out arm.
