Driving and driven sprockets 21 and 22 are provided at the lower and upper portions of the frame 15, and a circulating transport body 23, exemplified by a chain, is wound between the sprockets 21 and 22.

The drive sprocket 24 is fixed to the drive shaft 24, and the drive shaft 24 is connected to a drive source having a brake, clutch, etc. (not shown), and the circulation conveyor 23
is intermittently circulated in the vertical direction.

Reference numeral 25 denotes a shelf on which the extruded products 5 are placed, and a large number of shelves 25 are arranged on the circulation conveyance body 23 at equal intervals in the circumferential direction so as to protrude outward.

The shelf 25 scoops up the extruded product 5 that has been fed laterally from the lift transfer device 4 by the circulation of the circulation conveyance body 23 on the product loading side at the bottom of the elevator device 13, and
The extruded product 5 is transferred to the product take-out table 14 on the lower product take-out side.

Reference numeral 26 denotes a product transfer device, which transfers the extruded product 5 from the product carry-in side shelf 25 to the product carry-out side shelf 25 without rolling at the upper part of the elevator device 13, and includes an elevating cylinder 27 and a lift cylinder 27; cylinder 27
The frame 15 is moved through the guide device 28 by the expansion and contraction movement of
A lifting platform 29 that can be raised and lowered freely within the
Arm 3 pivoted via axis 30 to one side of

and a swing cylinder 37 pivoted with a pin 36.

Thus, in each elevator device 13, the corresponding pillars 18 on the same side at the front and rear are connected to the first communication pipe 38.
These are connected to each other at their lower ends.

Moreover, in the adjacent elevator device 13,
The pillars 18 on the same side corresponding to the front and back are the second communication pipes 3

According to the embodiment configured as described above, FIG.
The extruded product 5 transported to
The moving beam 48 is successively scooped up by the shelf 25 and placed on the shelf 25, and the moving beam 48 is lifted up by the elevator device 13.
retreat outwards.

In this case, since a large number of elevator devices 13 are arranged in rows at predetermined intervals in the longitudinal direction of the run-out table 3, even if the extruded product 5 is long, it is supported by the shelves 25 and is not bent during transportation. There is nothing to do.

The scooped extruded product 5 is intermittently raised by the circulation conveyor 23 until it reaches the highest position where the shelf 25 can maintain its horizontal position or a position near it. When the extruded product 5 on the shelf 25 is reached and stopped, the product transfer device 26 transfers the extruded product 5 on the shelf 25 onto the corresponding top shelf 25 on the product delivery side of the elevator device 25 without rolling.

That is, in the above case, the lift table 34 is raised together with the lift table 29 and the like through the extension of the lift cylinder 27, and the extruded product 5 on the uppermost shelf 25 on the product loading side is lifted.

Next, the arms 31 and 33 are swung by the swing cylinder 37, and the lift table 34 is moved to the product delivery side of the elevator device 13.

Thereafter, the lift table 34 is lowered together with the lift table 29 by the reduction of the lift cylinder 27, and the extruded product 5 is transferred from the lift table 34 onto the top shelf 25 on the product delivery side.

Next, the lift table 34 returns to its original position together with the lift table 29 by the operation of the lift cylinder 27 and the swing cylinder 37.

In this way, the top shelf 25 on the product delivery side
The extruded product 5 transferred to the top is transferred to the circulation transport body 23
As a result, the product is lowered on the product discharge side of the elevator device 13.

Then, the shelf 25 descends to the lower part of the elevator device 13. In this case, the product take-out table 14 is advanced below the shelf 25, and as the shelf 25 descends, the extruded products 5 are removed from the shelf 25. is transferred to the product take-out table 14,
Thereafter, the product take-out table 14 retreats toward the outside of the elevator device 13.

By the way, in the process of transporting the extruded product 5 by the elevator device 13, the extruded product 5 on each shelf 25 is heated by high pressure air from each cooling nozzle 44.
Good cooling is achieved on both the product loading and unloading sides.

In the embodiment, a pair of high-pressure air supply sources are used, but a single high-pressure air supply source may be used. Alternatively, the corresponding left and right columns may be communicated with each other by a connecting member.

<Effects of the invention> As detailed above, the present invention makes the frame of each elevator device hollow and communicates each frame with a communication pipe, so that each frame and the communication pipe constitute a high-pressure air supply path. and includes a high-pressure air supply source that supplies high-pressure air to the supply path, and each frame includes a cooling nozzle that cools the extruded product on the shelf by blowing high-pressure air from the high-pressure air supply source onto the extruded product. Therefore, by providing the cooling nozzle in the frame with its arrangement taken into consideration, the extruded product on the shelf can be easily and satisfactorily cooled. In addition, since no cooling fan is used, and the frames of each elevator device are hollow, each frame and the communication pipe that communicates these frames constitute a high-pressure air supply path, which reduces the cost of the cooling device. can be done cheaply. Furthermore, as mentioned above, instead of using a cooling fan, a cooling nozzle smaller than the cooling fan is used to blow high-pressure air onto the extruded product on the shelf, so the cooling device is not used to transport the extruded product. There is little risk of it getting in the way. The present invention has the above advantages and is of great practical benefit.
