Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shake-out machine device for removing molding sand attached to a rough casting product.

Conventionally, sand removal from rough castings was not sufficient, so several shake-out machines were arranged in series with a step difference, and the shake-out machines were passed through the top surface of the grate while vibrating. Foundry sand was being shaken off from rough castings. However, the difference in level between the shake-out machines was quite large, causing the raw material castings to get caught (in other words, in order to reliably transfer the raw material castings, it was necessary to provide a step). (Moreover, this step needs to be quite large because both the grate surfaces move up and down.)

In addition, if the shake-out machine is made long and multiple pieces of raw material castings are lined up on the top of the grate and sent out one by one by moving the feed claw in and out, it is possible to remove the claws from the rough material castings because it is a vibrating body. This made it impossible to position the rough castings on the shake-out machine in parts of several pitches or more.

The present invention has been made in view of these problems, and it is possible to take a long time to separate the rough casting product from the attached molding sand, thereby making it possible to remove sand sufficiently, and to eliminate the difference in level between the shakeout machines. It is an object of the present invention to provide a new shake-out machine device that eliminates biting of cast materials and also solves the problem of positioning when using feed claws.

The configuration of the present invention will be explained below based on examples. Reference numerals 1 and 2 denote an inlet conveyor and an outlet conveyor for the raw material castings 3, and a guide rail 4 is laid between the inlet conveyor 1 and the outlet conveyor 2, intersecting with the feeding direction of the crude material castings 3. A truck 6 is mounted on the upper surface of the guide rail 4 via wheels 5 so as to be movable, and on one side of the truck 6 is a support bracket 7 fixed to the foundation. A piston rod 8a of a rotatably supported truck cylinder 8 is connected to the truck 6, and the truck 6 is movable on the guide rail 4 by the operation of the truck cylinder 8. A support stand 9 is fixedly installed on the cart 6, and a spring 10 is mounted on the support stand 9.

The extrusion pushers 19 and 20 to which the extrusion pushers 1 and 2 are fixed are arranged horizontally, respectively.
By the extrusion operations of 9 and 20, the cast material 3 on the grate 13 is sent from the A' position to the A'' position and from the B position to the B' position. It is a gate-shaped frame with a structure in which the upper end of a vertical frame 23a to be installed is connected with a guide frame 24, and the guide frame 24 has rough material castings 3 on the lower surface at approximately equal intervals in the front and rear.
A traveling trolley 26 with vertical feed claws 25, 25a for loading and unloading is provided so as to be movable via wheels 27, and on the upper surface of the traveling trolley 26,
A piston rod 29a of a traveling cylinder 29 rotatably supported by a cylinder bracket 28 fixedly provided near the front of the guide frame 24 is connected via a support member 30.
Due to the operation of
It is designed to be moved along the road. A hanger bucket 31 is suspended from a guide rail 32 outside the carry-out conveyor 2, and the hanger bucket 31 moves in circulation along the guide rail 32 and stops at the position of the carry-out conveyor 2.

Next, the operation of the device configured as described above will be explained.

On the carry-in conveyor 1 (position A), there is a raw material casting 3 with molding sand attached before cleaning, and a grate 1
The rough casting product 3 on which the attached molding sand has been completely cleaned is placed at position B on the grate 13, and the rough casting product 3 on which the attached molding sand has been completely cleaned is placed on the A'' position on the grate 13. In the illustrated state in which the shakeout machine 12 is vibrated by the operation of the vibration motor 11, when the traveling cylinder 29 is retracted, the air on the conveyor 1 (A
The crude casting 3 before cleaning, which is located at position 3, is moved to position A' on the grate 13 by the feeding claw 25, and
Also, the cleaned cast material 3 at position A'' on the grate 13 is transferred to the conveyor 2 by the conveyor claw 25a for conveyance into the hanger bucket 31 (position A).
are sent to each. hanger bucket 31
The cleaned raw material castings 3 sent into the container are sent to the next process in the hanger bucket 31, and the rough material castings 3 moved to position A' on the grate 13 are subjected to vibration and are free from adhering casting sand and The casting burrs are shaken off, and the adhering casting sand and casting burrs that have been shaken off are collected through the gap between the grate 13 and the collection conveyor 18 below the shake-out machine 12 via the chute 17. Meanwhile, during this period, the rough casting 3 at position B on the grate 13 is subjected to a vibration action, and most of the adhering foundry sand is shaken off, and the extrusion pusher 19 pushes out the cast product 3 on the grate 13 to the extrusion plate 21.
is pushed and moved from position B to position B'. Next,
When the traveling cylinder 29 and the pushing pusher 19 are reversely operated to return the traveling carriage 26 and the pushing plate 21 to their original positions, the carriage cylinder 8 is retracted and the carriage 6 is moved to one side on the guide rail 4. , the rough material casting 3 at position A' on the grate 13 is positioned on the opposite line to the extrusion pusher 20, and is moved from the A' position to A'' on the grate 13 while being vibrated by the extrusion operation of the extrusion pusher 20. The rough cast product 3, which has been moved to the position and completely shaken off the adhering casting sand at the B' position by the retracting operation of the traveling cylinder 29, is moved to the feed claw 25a for carrying out.
is pushed into the hanger bucket 31 via the transport conveyor 2 and sent to the next process, and at the now empty position B, a new uncleaned cast material 3 is transported from the transport conveyor 1. It is guided by the feed claw 25 and carried in. Next, the traveling cylinder 29
When the push-out pusher 20 is reversely operated and returned to its original position, the carriage cylinder 8 is operated to push out the carriage 6, and the carriage 6 is moved on the guide rail 4 to the position shown in FIG. 1 and returned to its initial position. It will be done.
Thereafter, the above-mentioned operation is repeated, and the rough castings 3 are cleaned of adhering molding sand and are successively conveyed to the next process in the hanger bucket 31.

In short, a shakeout machine with two rows of moving passages is provided between an incoming conveyor and an outgoing conveyor so as to be movable back and forth in the cross direction, and extrusion pushers are provided on both sides of the incoming conveyor in parallel with the incoming conveyor. Above the shake-out machine, there is a running trolley, which has feed claws for carrying in and feed claws for carrying out vertically installed on the lower surface at a predetermined interval in the moving direction, and is arranged so as to intersect with the moving direction of the shake-out machine. Since the structure is such that the molding sand can be reliably separated from the rough castings, the rough castings will not get caught in the steps between the shake-out machines. Furthermore, it has excellent effects such as solving the problem of the feeding claw and the raw material castings getting caught, and the effect it has on this type of industry is extremely significant.
