Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a separate coating device for separating cores mounted on a pallet from the pallet and coating the separated cores with, for example, graphite.

For example, a core used for molding a socket part of a cast iron pipe is molded while being placed on a pallet, and is taken out together with the pallet.

Next, the core is separated from the pallet by lifting it with a crane, and the lifted core is coated with graphite or the like. In such conventional examples, slinging work using a crane is dangerous, and there is also a risk of falling off. Furthermore, since workers perform painting work while walking around the lifted core, work efficiency is poor and it is difficult to achieve a clean finish. The present invention proposes a separate coating device that can solve the above problems.

That is, the present invention provides a bracket that can be rotated forward and backward around a vertical axis, a rotation drive device for this bracket, and a horizontal axis provided on the bracket that is supported so as to be movable around a horizontal axis. a frame body, a passive drive device for the frame body, a conveyor disposed on the upper surface side of the frame body and capable of carrying a pallet on which annular cores are spread onto and from the frame body. , comprising an elevating frame that is guided in a vertically movable manner by a pair of guide rods erected on the frame body, and the elevating frame is capable of holding an elevating drive device for the elevating frame and an inner circumferential surface of the core. It has an open/close type arm punch, and is inserted into the core from above the core carried onto the frame by lowering the lifting frame,
and a holding device that moves the core held by the arm punch above the pallet by raising the lifting frame, an opening/closing drive device for the arm village, and a rotation drive device that rotates the core together with the holding device. It has been established.

According to this configuration, by raising the holding device with the lifting device while holding the cores in the holding device, the cores can be separated from the pallet safely and without falling off. . In addition, with the core raised, the holding device, that is, the frame body, is moved one turn around the horizontal axis, and the holding device is rotated by the rotary drive device, so that the tilted core can be moved around the center of the tilted core. It can be rotated around the core of the sea bream, and therefore the core can be painted with graphite or the like easily and neatly by a worker with a fixed position calendar. Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 29 denotes a rotation drive device for rotating the holding device 17, which includes a motor 30 attached to the lifting frame 16, a drive gear 31 attached to its output shaft, and a rotation drive device 29 that is always aligned with the drive gear 31 and rotates the cylinder shaft 18. It consists of a passive gear 32 attached to. The elevating frame 16 is the frame body 1
It is guided so as to be movable up and down by a pair of guide rods 33 erected from above. The holding device 17 is provided between the frame body 1 and the holding device 17.
An elevating device 34 is provided as an elevating drive device for elevating and lowering. That is, a pair of left and right L-shaped links 35A, 35B whose intermediate portions are pivotally supported is provided on the frame 1 side, and one end of these L-shaped links 35A, 35B is connected to rollers 36A, 36B.
It is connected to the elevating frame 16 through long holes 37A and 37B. Then, the ends of the L-shaped links 35A and 35B are connected by a bar 38, and one connecting part and the lifting frame 1 are connected.
A lifting shilling device 39 is provided between the holder and the holder 6. 4 river molding furnaces, 41 is a drying furnace, and both furnaces are arranged with a phase difference of 90 degrees.

42 is a conveyor for carrying out pallets facing the drying oven 41, and is connected to a conveyor 43 capable of drying.

Before work, both conveyors 2 and 3 face the molding furnace 40 side, and the elevating frame 16 is raised together with the holding device 17 and the like.

Further, the holding device 17 is contracted so that each bush abutment plate 27 is in the innermost position. In such a state, the molding furnace 4
A pallet 15 made up of cores 14 is sent out from 0, passed to conveyors 2 and 3, and stopped directly below a holding device 17. Next, the lifting cylinder device 39 is retracted, the lifting frame 16 is lowered, and the holding device 17 is inserted into the core 14 as shown by the solid line in FIG. In this state, the motor 30 is started, and each arm 25 is swung outward to bring each hair contact plate 27 into pressure contact with the inner circumferential surface 14a, as shown by the solid line in FIG. 1 and the imaginary line in FIG. 4. As a result, core 1
4 can be held by a holding device 17. Next, the lifting cylinder device 39 is extended, the lifting frame 16 is raised via the L-shaped links 35A and 35B, and the core 14 is lifted up via the holding device 17 as shown by the imaginary line in FIG. In this state, the rotating cylinder device 8 is extended, the frame 1 is rotated 90 degrees around the vertical axis 9, and the conveyors 2 and 3 are opposed to the pallet conveyor 42. Then, the pallets 15 on the conveyors 2 and 3 are carried out to the pallet carrying-out conveyor 42 side. Next, the pivoting cylinder device 13 is extended, and the frame 1 is moved around the horizontal axis 12 as shown in FIG.
The core 14 is tilted. In this state, the rotary drive device 29 is started to rotate the core 14 while coating the outer peripheral surface 14b of the core 14 with graphite or the like. Next, the moving cylinder device 13 is contracted to return the frame 1 to a horizontal position, and the lifting cylinder device 39 is contracted to lower the lifting frame 16, and the core 14 is lowered onto the conveyors 2, 3. Thereafter, the arm punch 25 is retracted by reverse rotation of the motor 28 to separate the contact plate 27 from the inner peripheral surface 14a, and the core 1 is held by the holding device 17.
Release the hold on 4. Next, the holding device 17 is raised together with the elevating frame 16 and extracted from the core 14. Then, the frame body 1 is rotated 90 degrees so that the conveyors 2 and 3 face the drying oven 41, and the cores 14 on the conveyors 2 and 3 are carried into the drying oven 41 for desired drying. Thereafter, the frame body 1 is rotated 90 degrees and returned to its original position, and assumes the initial standby position.
According to the separation coating device of the present invention described above, by lifting the holding device with the holding device while holding the cores, the cores can be separated from the pallet safely and dropped. You can do it without any trouble.

In addition, with the core raised, the holding device is moved around the horizontal axis, and the holding device is rotated by the rotary drive device, so that the inclined core is moved around the inclined axis. It can be rotated, and therefore the core can be coated with graphite or the like easily and neatly by the worker in the stereotactic layer.
