Abstract

PURPOSE:To make products projectable into a shot blasting cabinet with certainty, by lifting a bucket loader up to the specified position and tilting it in movements, while repeating this tilting operation several times for projecting these products into the cabinet, in case of shot blasting for polishing these casting products. CONSTITUTION:A receiving box 11 in which casting products are housed is mounted on a truck 12 and housed inside a bucket loader 9 so as to cause a projecting part 13 of the receiving box 11 to be engaged with a rail 10. Next, a rocking arm 17 is turned round with extension of a cylinder 14, moving the loader 9 and the receiving box 11 upward and making them into horizontality, and successively they are inclinatorily moved with extension of the cylinder 15 whereby these housed products are accurately projected onto an apron conveyor 7 in a way of repeating tilting movements several times by means of the cylinder 15. And, when operation by a shot blast 1 is over, the conveyor 7 is reversely rotated and thereby these products are discharged to a vibrating conveyor 27. On the other hand, the loader 9 is restored to its original position as soon as projection is over. Thus, the remnant of these products due to bridging is prevented from occurring and they are projectable with certainty in this way.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a cleaning tool F-plast for cleaning the casting surface of a cast product (hereinafter simply referred to as a product) that has undergone a demolding process, and more particularly to Cleaning method 1! Concerning equipment for introducing products.

Conventional technology In the past, products were generally loaded into a storage warehouse by tilting a box-shaped packet loader installed opposite the product entrance of the storage warehouse toward the product entrance after receiving the product. However, in this method, products must be loaded into the packet loader using a crane, forklift, etc., which is troublesome. Therefore,
Separately from the packet loader, a product receiving box is provided that allows the packets to be taken in and out, and the product is loaded into the product receiving box at a separate location, inserted into the packet loader, and then tilted together with the packet loader. A packet separation type (cartridge type) in which input is performed has also been proposed.

However, in all of the above systems, the product is loaded by pulling up the bucket (C2-da) along a pillar or rail using a chain and tilting it toward the product input port, and in that case, the product is loaded into the bucket by using a chain. Due to misalignment, etc., the product may get stuck during loading and remain in the packet loader or product receiving box, and the above-mentioned residual phenomenon occurs particularly when the product is handled with a weir attached. OBJECT OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the conventional device described above, and to
To provide a product loading device for shot blasting that can surely load products without leaving any products in a packet loader or a product receiving box.

Components of the Invention The present invention involves loading a product receiving box containing products into a packet loader, raising the box to a nearly horizontal position using a first cylinder, and then loading the product using a second cylinder. By repeating the tilting motion for loading multiple times, vibrations are applied to the product and the product is loaded.

Embodiments Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 in the figure is an apron conveyor type sheet blast.
A product entrance/exit 3 formed in the cabinet 2 can be opened and closed by a door 6 that is raised and lowered by a hoisting drum 5 along a columnar rail 4. cabinet 2
An apron conveyor 7 that rotates at a slow speed is installed inside the casting, and the product is agitated by the apron conveyor 7 while being shot with shot material (steel slabs) by an in-veler 8 so that the casting surface is cleaned. It has become.

First, a product loading device for loading products to be cleaned into the cabinet 2 of the Ift Blast 1 will be explained. As shown in the figure, the packet loader 9 installed opposite to the product entrance 6 of the cabinet 2 at a predetermined distance has a chute section 9a on the upper side and a receiving box storage section 9b on the lower side. It is formed in a groove shape, and groove-shaped rails 1o are provided on both inner surfaces of the receiving box storage part 9b.
is fixed horizontally. On the other hand, when the packet loader 9 is in the upright state, the rectangular product receiving box 11 for storing the product is transferred to the receiving box storage portion of the packet loader 9 via, for example, a self-propelled carrier 12. b is said to be able to enter and leave υ,
The rails 1 of the receiving box storage section 9b are provided on the outer surfaces of both sides when charging.
A horizontal projecting portion 13 that can be inserted into the 0 is provided in a protruding manner.

Thus, the packet loader 9, with the product receiving box 11 housed therein, is tilted to load the product by means of two hydraulic cylinders 14 and 15.

That is, a pair of left and right swinging arms 17 having a triangular shape are mounted on the upper part of a pair of left and right support stands 16 that are set upright on the floor, and one end of the swinging arms 17 can swing around a horizontal axis via a rotation shaft 18. A placket 19 fixed to the belly plate of the packet loader 9 is supported at the top end of the swing arm 17 via a pin 20 so as to be rotatable around a horizontal axis. A first cylinder 14 is disposed vertically on one side between the left and right support stands 16, and the cough cylinder 14 has a U-shaped bracket 21 fixed to one of the support stands 16 at approximately the center thereof. is rotatably supported via a pin 22, and the tip of the piston rod 147L is connected to one swing arm 17.
is connected to via a pin 26. Further, the second cylinder 15, which is disposed horizontally at approximately the center between the left and right swing arms 17, is rotatable via a pin 25 on a cylinder bracket 24 whose one end is fixed to the rotation shaft 18. In addition to being supported, the tip of the piston rod 15a is connected to the placket 19 of the packet loader 9 via a pin 26.

Note that 27 is a vibrating conveyor for carrying out the cleaned products.

This embodiment is constructed as described above, and its operation will be explained below.

When a specified amount of products (with weirs) that have completed the demolding process and the cooling process are counted into the product receiving box 11, the receiving box 11 is loaded onto the transport vehicle 12 and loaded onto the packet loader 9. Inbox storage department? b and is on standby, at which time the protrusion 16 of the product receiving box 11 is connected to the rail 1 of the packet loader 9.
It is set to 0.

On the other hand, when the projecting work of the shitt material is completed in the shittgoufnut 1, the door 6 is raised by the hoisting drum 5 and the product entrance/exit 6 is opened, and the apron conveyor 7 is rotated in the opposite direction to vibrate the product. It is carried out onto the conveyor 27.

In this way, when the cabinet 2 of the shot blaster 1 is empty and ready to receive the next product, the first cylinder 14 is extended and the packet loader 9 and product receiving box 11 are opened as shown in FIG. is tilted upward with a large rotation radius around the fulcrum (rotation shaft 18) of the swing arm 17, and changes from an upright position to a substantially horizontal position. Next, the second cylinder 15 is extended, and the packet loader 9 and the product receiving box 11 are further tilted at a small rotation radius about the fulcrum (pin 20) of the baget 19.

The packet loader 9 is tilted so that its chute 9& is inserted into the product inlet/outlet 5 of the shot blaster 1. Therefore, the product slides or rolls on the chute portion 9a and is dropped onto the apron conveyor 7 inside the cabinet 2.

Next, after an appropriate period of time (time required for dropping the product), the second cylinder 15 is contracted to return the packet loader 9 to its original, substantially horizontal position, and then extended and tilted again. That is, the packet loader 9 repeats the tilting action for loading the product twice or six times, and as a result, when the packet loader 9 is tilted for the first time, the product may become stuck in the product receiving box due to, for example, mutual entanglement of the products. 11
Even if there is a bridge inside or in the chute section 9a,
The bridging phenomenon is canceled by the vibration caused by the repetition of the tilting action, so that it will be inserted without remaining during the next tilting operation. Also, at this time, since there is backlash between the packet loader 9 and the product receiving box 11, which have a double box structure, there is a shock between them, and the impact is effectively applied to the product receiving box 11 itself and the packet loader 9. It is extremely effective in removing bridges from the above-mentioned products.

In this way, when the product input is completed, the second cylinder 15
Then, the first cylinder 14 is sequentially contracted and the packet loader 9 is returned to its original position in an upright position, and the empty product receiving box 11 is loaded onto the waiting carriage 12. On the other hand, in the shot blasting machine 1, the door 6 is lowered to close the product entrance/exit 5, and a predetermined cleaning action is performed. What is the stopping position of the packet loader? The tilting position of is regulated by a limit switch.

Effects of the Invention As detailed above, the present invention is arranged so that the tilting action for loading the product is repeated multiple times while the packet loader loaded with the product receiving box is raised and tilted to a predetermined position. In addition, it is possible to prevent products from remaining due to bridging due to vibrations caused by repeated tilting, and to reliably feed products into shot blasting. This is effective when bridging is likely to occur due to entanglement.
