BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning device for transferring a casting discharged from a casting device to a next conveying device.

[0002]

2. Description of the Related Art In order to send out a cast product discharged through a casting process to a next sand removal process, the cast product must be transferred from a pay-out conveyor to a suspended conveyor for sand removal. However, in this method, the casting is extruded to the side of the paying-out conveyor by a transfer device arranged so far at one end of the paying-out conveyor, and is positioned at a predetermined position immediately below the suspended conveyor. Was.

[0003] However, when the cast product has a non-flat side surface such as a cylinder head as a positioning reference, it is extremely difficult to accurately position the bearing at the supporting position, and the external shape differs depending on the model. In the case of such a device, it is necessary to use a positioning tool suitable for each of them, and an exchange device for that is required, and if such a mechanism is incorporated in a transfer device, the device is further complicated. Such a problem arises.

[0004]

[Problem to be solved by the present invention] The present invention has been made in view of such a problem.
An object of the present invention is to provide a positioning device for a cast product that can be accurately positioned by using a runner portion whose position is constant even when the shape is changed or the like.

[0005]

That is, the present invention is a transfer device for transferring a casting discharged from a casting device to a next transfer device as a casting positioning device for achieving the above-mentioned object. the mechanism, the pair of positioning members which is displaced toward the casting is driven by a drive member with opposite disposed, the opposing surfaces of the positioning member, the casting
Engage with each of a plurality of runners remaining in a specific part
A plurality of V-shaped positioning engagement recesses are formed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The drawings show one embodiment of the present invention,
The apparatus 1 is disposed at the end of the pay-out conveyor 30 and moves the discharged cast product, that is, in this embodiment, the cylinder head W together with the pallet P to the position directly below the lateral hanging-type transfer device 40. Slide mechanism 10 to move
And a positioning mechanism 20 for positioning the cylinder head W at a fixed position on the slide mechanism 10.

Next, each of these mechanisms will be described in more detail. A machine frame 2 is installed at the end of the paying-out conveyor 30 in a direction orthogonal thereto, and a slide mechanism 10 is mounted on the base plate 3. Side feed cylinder 11
It is arranged so that it can be driven and driven freely.

The slide mechanism 10 moves the pallet P on the payout conveyor 30 directly below the transport device 40. As shown in FIG. 2, the slide base 12 has the payout conveyor 30 at the center thereof. Rail 3
A rail 13 connected to the pallet 1 is mounted, and a lifting cylinder 14 for lifting the pallet P from the rail 13 is provided directly below the rail 13. Reference numeral 15 in the figure denotes a rail 13 for suppressing the lateral movement of the pallet 5.
Are shown on both sides.

On the other hand, the positioning mechanism 20 performs positioning by sandwiching a runner portion a protruding above the cylinder head W. Each pair of positioning mechanisms 20 has columns 17, 17 at both ends of the slide base 12. In particular, in this embodiment, two cylinder heads W, W mounted on a pallet P are positioned, as shown in FIG. Two sets are provided so that the

These base plates 18, 18 have positioning cylinders 21, 21 and guide rails 23, respectively.
23 are provided facing the cylinder head W, and rod ends of these positioning cylinders 21 and 21 have
Plates 24, 24 which are guided and guided by guide rails 23, 23 are mounted. These plates 2
Guide rails 25, 25 are fixed to the front surface of each of the plates 24, 24 in a horizontal direction.
Positioning blocks 28, 28 which are connected to positioning cylinders 26, 26 provided on the back of 24 via brackets 27, 27 are slidably mounted in the lateral direction.

The positioning blocks 28, 28 are provided with V-shaped engaging grooves 29, 29 for engaging runners a, a remaining on the cylinder head W on opposing surfaces. The cylinder head W is configured to be positioned by engaging the grooves 29 with the runners a.

In FIG. 4, reference numeral 32 denotes a casting device. In FIG. 1, reference numerals 4 and 4 denote stoppers provided at both ends of the base plate 3, reference numeral 41 denotes a lifting cylinder of the transfer device 40, reference numeral 42 denotes a guide rail, Numeral 43 indicates a gripping mechanism.

In the apparatus constructed as above, the cylinder head W now formed from the casting apparatus 32 is placed on the pallet P and discharged, and is further moved onto the rail 13 of the slide mechanism 20 waiting at the end thereof. When being sent, the lifting cylinder 14 on the slide base 12
The rod is extended to raise the cylinder head W sent in from the position indicated by the two-dot chain line in FIG. 1 to the position indicated by the solid line in FIG.

When the cylinder head W is moved to the positioning position in this manner, a pair of positioning mechanisms 20 provided on both sides of the cylinder head W actuate the positioning cylinders 21 and 21 to move the rod end to the rod end. Positioning block 2
8 and 28 are advanced and the runner portions a and a on the cylinder head W are sandwiched by the positioning blocks 28 and 28 that have been accurately aligned in the lateral direction by the positioning cylinder 26 in advance, and The cylinder head W is moved slightly back and forth and left and right while the road portions a and a are engaged in the engagement grooves 29.

When the above positioning operation is performed,
Next, the lateral feed cylinder 1 fixed to the base plate 3
1 is operated to position and hold the cylinder heads W,
W is transported together with the pallet P to a position immediately below the transport device 40, and the cylinder head W is delivered to the transport device 40 that has descended.

When the above series of operations is completed, the positioning blocks 28, 28 are retracted by the reverse operation to return the slide base 12 to the original position, and then the pallet P is paid out by a lifting mechanism (not shown). Put it on standby.

[0017]

As described above, according to the present invention, a pair of positioning members for holding a cast product are displaceably opposed to a transfer mechanism for holding the cast product and transferring it to the next transfer device. Arrange the cast parts on the opposing surfaces of these positioning members.
Since a plurality of V-shaped positioning engagement recesses for engaging with the plurality of runner portions remaining on the upper surface are provided, the hot water remaining on this surface regardless of the shape of the cast product. Each of the provinces,
So as to follow the left and right V-shaped slopes provided in each engagement recess.
Correct and by Komu dropped in the middle of the valley, the castings
Positioning can be performed in a correct direction .

[0018] Moreover, as the die cast, the runner portion in casting to be molded to be formed in the same position, the shape of the casting was Tsu strange <br/> by example models by the same casting device In such cases, the same positioning member can be used to correct the casting without changing the positioning member each time.
The positioning and the operation required for this type of positioning can be greatly simplified.
