In the product transfer device configured as described above, the front panel 1 placed on the parrot 10 is fixed by the first positioning holes 21 and the second positioning holes 31 to prevent horizontal movement. And transfer to a predetermined position by rotation of the turntable 3 are the same as in the conventional product transfer apparatus described with reference to FIG. However, in the product transport apparatus of this embodiment, it is easy when the distance between the first positioning pin 21 and the second positioning pin 31 is to be changed because the size of the product to be placed on the parrot 10 is changed. It is possible to cope. Hereinafter, a method of responding to the case where the distance between the first positioning pin 21 and the second positioning pin 31 should be changed as described above will be described.

For example, as shown in FIGS. 2 and 3, the positioning protrusion 23 of the first movable body 20 is accommodated in the protrusion storing groove 41 of the positioning tool 40 and the protrusion storing groove 44. When the distance between the first positioning pin 21 and the second positioning pin 31 is to be changed in a state where the positioning projection 33 of the second movable member 30 is accommodated, first, The first pneumatic cylinders 65 and 75 are operated to access the pressing members 60 and 70 to each other as shown in FIG. Then, when the pneumatic cylinder 55 is operated to raise the elevating plate 53, the pressing members 60 and 70 press the positioning tool 40 as shown in solid lines in FIG. The sphere 40 is raised. Accordingly, the projection receiving grooves of the positioning tool 40 which are coupled to the first positioning protrusion 21 on the first movable body 20 and the second positioning protrusion 31 on the second movable body 30 ( 41 and 44 exit from the positioning protrusions 21 and 31. When the positioning tool 40 is released from the positioning protrusions 21 and 31 in this way, and then the first pneumatic cylinders 65 and 75 are operated in reverse, the pressing members 60 and 70 It moves in the direction away from each other. During the movement, the pressing members 60 and 70 press the moving bodies 20 and 30, respectively, and are spaced apart from each other as shown by the solid lines in FIGS. 6 and 4.

As described above, in the state where the moving bodies 20 and 30 are spaced apart from each other, the second pneumatic cylinder 91 and the third pneumatic cylinder 93 are selectively operated to raise the stopper member 80 to an appropriate position. . For example, when the stopper member 80 is raised to the position shown by an imaginary line in FIG. 4, the block portion 82 of the block portions 81, 82, and 83 of the stopper member 80 moves the movable bodies 20. Specifically, it faces the downwardly protruding pieces 24 and 34 of the moving bodies 20 and 30.

In this state, the pressing members 60, 70 are moved by the first pneumatic cylinders 65, 75 again as shown in solid lines in FIG. Terminate Accordingly, the movable bodies 20 and 30, which have been moved in the direction spaced apart from each other by the pressing members 20 and 30, are elastically moved in the direction of mutual access again by the restoring force of the springs 29 and 39. Done. As described above, the moving bodies 20 and 30 move along the block portion 82 of the stopper member 80 in which the downwardly protruding pieces 24 and 34 are raised, as shown by a virtual line in FIG. 4. ) The movement stops. At this time, the positioning protrusion 23 of the first movable body 20 is located vertically above the protrusion storing groove 42 among the raised protrusion grooves of the positioning tool 40, and the second movable body 30 The positioning projection 33 is located vertically above the projection receiving groove 45 of the positioning tool 40.

In this state, when the lifting body 53 is lowered by operating the pneumatic cylinder 55, the positioning tool 40 is lowered by the restoring force of the spring 17a, and the positioning projections 21, 31 is fitted into the projection receiving grooves 42 and 45. Therefore, when the lowering of the positioning tool 40 is completed and the positioning tool 40 is brought into close contact with the upper surfaces of the bracket portions 22 and 32, the positioning protrusions 23 and 33 and the projection storing grooves 42 The movable bodies 20 and 30 are fixed in position by the coupling between the movable bodies 20 and 30, and the first positioning pin 21 and the second movable body 30 coupled to the first movable body 20 are coupled to each other. The distance between the second positioning pin 31 is the projection storage groove 44 and the projection storage groove in the interval between the projection storage groove 41 and the projection storage groove 42 in the state shown in Figs. The distance between the 45 and the further distance. In this way, the distance between the first positioning pin 21 and the second positioning pin 31 can be changed in multiple steps.

As can be seen from the above description, when the specification of the product is changed so that the distance between the positioning pins 21 and 31 for positioning of the product is to be changed, the product transport apparatus of this embodiment is arranged on the turntable 3. Even if the parrot 10 itself is not replaced, since the distance between the positioning pins 21 and 31 is changeable, it is possible to easily cope with the change of the standard of the product.

The product transport apparatus of the present invention is not limited to the configuration of the above-described embodiment, and the device having various configurations can be easily configured by those skilled in the art without departing from the claims of the present invention.

For example, in this embodiment, the stopper member 80 is configured to be selectively positioned at four vertical positions so that the distance between the first positioning pin 21 and the second positioning pin 31 is three steps. Although it can be adjusted to, for example, when one more pneumatic cylinder is used together with the second pneumatic cylinder 91 and the third pneumatic cylinder 92, the stopper member 80 is selectively positioned in eight vertical positions. The distance between the first positioning pin 21 and the second positioning pin 31 can be adjusted in a maximum of seven steps. In addition, when a motor is used instead of the above-described pneumatic cylinders 91 and 92, the stopper members 80 may be lifted by a single motor in multiple stages.

In addition, a cylinder for elevating the base 51 supporting the pneumatic cylinders 55, 91, and 92 may be provided. In this case, the degree of freedom of design may be further increased.

In this embodiment, although the position change unit 50 is installed below the conveying means to automatically adjust the distance between the positioning pins 21 and 31 on the parrot 10, the position change unit is not provided. If necessary, the operator may directly adjust the distance between the positioning pins. In such a case, it is difficult to automatically change the distance between the positioning pins, but the inconvenience and cost increase that must be provided with several types of parrots according to the specifications of the product can be prevented.

In the present embodiment, the turntable 3 is used as a conveying means for conveying the parrot 10 and the product 1 on the parrot 10. For example, a belt conveyor, a roller conveyor, or the like is used. Of course, the present invention can also be applied to a device having a transfer means.

As described above, the product transport apparatus according to the present invention supports a product and is placed on a transport means so that the parrot conveyed by the transport means is capable of being moved in a direction in which the main body and the main body are mutually approached and spaced apart from each other. And a pair of movable bodies to which the positioning pins for positioning of the product are coupled, and a parrot position fixing means for selectively positioning the movable bodies in any one of a plurality of positions. Therefore, it is possible to easily cope with the case that the distance between the positioning pins for positioning of the product should be changed by changing the specification of the product to be placed and supported on the parrot, and it is possible to suppress the increase in the cost.
