Abstract

(57) [Summary] [Purpose] Mechanically inspect defective tiles by hammering. [Structure] A tile transfer conveyor 1 in which an exclusion space S is formed between transfer tools 3 and 3 on both sides including a transfer belt, and hammers 6 are naturally driven from above the exclusion space S toward the tile transfer conveyor 1. And a tile striking device 2 for dropping the hammers 6 and 6 to the standby position.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a device for inspecting a defective tile that is easily cracked such as a crack or a non-defective tile.

[0002]

[Prior Art]

 Conventionally, inspecting tiles has been performed by an inspector using a hammer to hit the tile with a predetermined force. Defective tiles crack and good tiles emit a constant sound.

[0003]

[Problems to be solved by the device]

 However, the conventional inspection method performed by the inspector has the following problems. (A) Since it is a manual work, the inspection efficiency is very poor. (B) A considerable amount of skill is required to adjust the tapping force and to distinguish the sounds. (C) It is dangerous for the inspector because the defective tile is broken.

In order to solve the above problems, an object of the present invention is to provide a device for crushing and removing defective tiles which mechanically inspects tiles.

[Means for Solving the Problems]

 The means adopted by the apparatus for crushing and removing defective tiles (hereinafter referred to as the “apparatus of the present invention”) according to the present invention is a tile that is provided with conveyors on both sides, such as conveyor belts, and has a discharge space formed between the conveyors on both sides. It consists of a transfer conveyor and a tile striking device that causes the hammer to naturally drop from above the discharge space toward the tile transfer conveyor and lifts the dropped hammer to the standby position.

[0005]

[Action]

 The conveyor conveys the inspection tile to below the tile striking device while supporting both sides of the inspection tile. The tile striking device causes the waiting hammer to fall naturally toward the inspection tile being transported. The inspection tile receives the impact energy of a hammer that falls naturally, and crushes defective products with cracks and removes them into the discharge space below, and in the case of non-defective products, they are carried out by the conveyor without breaking. It The hammering energy is kept constant because the hammer naturally drops from the standby position to the tile position.

【Example】

 Hereinafter, the device of the present invention will be described based on the embodiment shown in FIGS. FIG. 1 and FIG. 3 are front cross-sectional views as seen in a state of traversing a conveyor, and FIG. The device of the present invention includes a tile conveyor 1 and a tile striking device 2.

The tile transfer conveyor 1 is equipped with transfer tools 3 and 3 on both sides, such as a transfer rope or a transfer belt stretched from side to side, and supports the inspection tile T at both ends while supporting the inspection tile T at an appropriate speed. To transport. A discharge space S for discharging the crushed defective tile pieces (not shown) is formed between the transport tools 3, 3 on both sides.

The tile striking device 2 includes a frame 4 provided so as to straddle the tile transport conveyor 1, an elevating device 5 including an air cylinder attached to the frame 4, and the tile transport conveyor 1 from above the exclusion space S. It has a hammer 6 that naturally falls toward.

The lifting device 5 has a hammer lifting tool 7 attached to the lower end of the output shaft 5a. The hammer holder 7 is formed in a U-shaped cross section, and the output shaft 5a is connected to the upper end piece 7a, and guide holes 8, 8 penetrating in the vertical direction are formed near the front and rear of the lower end piece 7a. is there.

The hammer 6 is provided with a weight portion 10 at the lower end of the shaft portion 9 and a flange portion 11 at the upper end of the shaft portion 9 so that the shaft portion 9 can be vertically moved into the guide hole 8 of the hammer holder 7. It has been inserted. The weight unit 10 adjusts the weight according to the type of the inspection tile T. A thrust bearing (not shown) may be provided between the shaft portion 9 and the guide hole 8 as necessary to reduce the frictional resistance. The number of hammers 6 may be one or three or more depending on the size of the inspection tile.

The stroke of the elevating device 5 is from a standby position for lifting the hammer 6 (see FIG. 1) to an inspection position for striking the inspection tile T with the hammer 6 (see FIG. 3), depending on the type of the inspection tile T. To adjust. Further, the descending speed of the output shaft 5 of the lifting device 5 is set higher than the natural falling speed of the hammer 6.

A tile piece removing device 13 for removing crushed defective tile pieces (not shown) is provided below the tile transfer conveyor 1. The tile piece removing device 13 includes a sheet 14 for guiding the tile pieces and an exclusion belt conveyor 15.

Next, a tile inspection method using the device of the present invention will be described. The inspection tile T is transported to below the tile striking device 2 by the transport conveyor 1. The tile striking device 13 actuates the elevating device 5, and causes the hammers 6 and 6 that are on standby to fall naturally toward the inspection tile T that is being conveyed. The inspection tile T receives the impact energy of the hammers 6 and 6 that fall naturally, and if it is a defective product with cracks, it is crushed and removed to the tile piece removing device 13 below. Carry out to the next process on the conveyor 1 without breaking. The hammers 6 and 6 that have fallen are immediately lifted to the standby position by the operation of the elevating device 5, and then the operation of naturally falling toward the inspection tile T is repeated in the same manner as described above.

[0014]

[Effect of the device]

 As described above in detail, the device of the present invention has the following practical effects. Since the tiles are conveyed by the conveyor and the hammer is naturally dropped by the tile striking device, the inspection can be automated and the inspection efficiency can be dramatically improved. Since the hammer striking energy can be maintained constant, the inspection content is always constant, and highly reliable inspection can be performed. The broken defective tiles are removed to the exclusion space, providing a safe working environment.
