However, hereinafter, the present invention will be described with a representative example of shot blasting a flow path form made of an aluminum material.

However, it is obvious that the present invention can be applied to other foams having a large area and side thickness, such as sliding foam, crime foam, gang foam, and al-foam in addition to the euro foam.

1 and 2 show a shot blasting device for foam using a transfer device according to a preferred embodiment of the present invention, and FIG. 1 is a front view of the present invention, and FIG. 2 shows a side view of the present invention, respectively.

As shown in the present invention, the input side transfer device 110, the process chamber 120, the process side transfer device 130, the impeller unit 140, the projection material feeder 150, the air injection unit 160, the discharge It includes a side transfer device 170, a projection material recovery device 180, and a foreign matter treatment device 190.

In the present invention, shot blasting is performed by spraying a projection material on the surface of a form. Typically, various foreign substances such as mortar adhered to the flow path form made of aluminum are removed (washed) and reused (regenerated). Make it possible.

To this end, the foam injected into the process chamber 120 through the input-side transfer device 110 is transferred by the process-side transfer device 130, and the projectile material supplied from the projectile feeder 150 during transfer is transferred to the impeller unit ( 140) to clean the surface of the foam.

In addition, the foam after the shot blasting process in the process chamber 120 passes through the air injection unit 160 and the projection material and foreign matter remaining in the foam are removed, and the foam passing through the air injection unit 160 is discharged from the discharge side. It is discharged to the loading space by the transfer device 170.

On the other hand, the projection material projected on the foam is collected through the bottom of the process chamber 120 and then recovered through the projection material recovery device 180, and the projection material from which the foreign material is removed by the foreign material treatment device 190 during recovery is a damper. It is provided to the projection material feeder 150 through (see '187' in FIG. 7B) to continue shot blasting.

Accordingly, the present invention regenerates the contaminated foam by washing it with a shot blast. In particular, by adjusting the injection angle of the impeller unit 140 according to the foam having a large area and side height, it is optimized to remove attached foreign substances. In addition, only foreign substances are separated so that the projection material can be reused, and a fixed amount of the projection material can be supplied through the damper 187.

More specifically, the input-side transfer device 110 transfers and inputs a foam having a large area and a certain height on the side, such as a flow path, to one side, and is installed at a height for easy operation on the floor surface of the workplace.

On the downstream side of the input-side transfer device 110, a process-side transfer device 130 and a process chamber 120 that covers and seals the same are disposed, so that the foam injected by the input-side transfer device 110 is disposed within the process chamber 120. Shot blasting is performed while being transported in.

However, the input side conveying device 110 may be a roller conveyor in which rollers 112 rotated by a motor 111 are arranged at regular intervals as shown, but if necessary, a mesh or belt type conveyor Etc. can also be applied.

In the process chamber 120, the projection material is sprayed onto the injected foam, and as an example, a metal enclosure having a designed length is used. Accordingly, when the projection material is sprayed at a high speed, the projection material is prevented from protruding to the outside and thus the work environment is impaired, and the projection material can be collected and recovered.

In addition, an inlet 121 is formed at the right end of the upstream side based on the direction in which the foam is transported, and an outlet 122 is formed on the opposite side thereof, and at this time, the input side transfer device 110 is connected to the upstream side, The discharge side transfer device 170 is connected to the downstream side.

In addition, a process-side transfer device 130 is installed inside the process chamber 120. As the process chamber 120 is installed to cover the upper and lower portions of the process-side transfer device 130, the upper and lower portions thereof are The impeller unit 140 installed in each enables shot blasting.

The process-side transfer device 130 is for transferring the foam inside the process chamber 120, and has a'penetration part' so that projection material can be sprayed from the upper and lower sides of the process-side transfer device 130, respectively. Consists of

In FIG. 1, the process-side conveying device 130 illustrates a mesh conveyor as an example. When the mesh conveyor type is applied, the mesh belt 131 is supported by a support roller 132 and a tension roller 133 so as to rotate along an endless track. And it is fastened to the tension adjustment device (134).

At this time, the'penetration part' that allows the projection material to be sprayed corresponds to the mesh eye, which is an empty space between the meshes constituting the mesh belt 131, and the mesh eye is from the lower part of the process-side transfer device 130 It has a size set large enough so that the jetted projection material reaches the foam overlying it.

However, in the present invention, the process-side conveying device 130 may be a conveyor composed of a plurality of conveying rollers or chains spaced at regular intervals. Therefore, the gap is widened as much as possible to the limit of preventing the foam from falling.

The impeller unit 140 is installed in the process chamber 120 and sprays the projectile at high speed from the upper and lower portions of the foam being transferred by the process side transfer device 130 therein. For example, the projectile is a short ball or bead and Use the same abrasive.

As can be seen more clearly through FIG. 2, the impeller unit 140 includes a projection motor 141, a projection guide 142 and an impeller 143, of which the projection motor 141 is of high speed. It is axially connected to rotate the impeller 143 at RPM.

In addition, the impeller 143 is installed inside the projection guide 142, and the impeller 143 has a plurality of blades radially installed around the rotation axis, so that when the impeller 143 rotates at high speed, the projection guide 142 The projectile injected into the interior is hit by the impeller 143 and injected at high speed.

On the other hand, as shown in Figure 3, the impeller unit 140 is transferred from the lower part of the upper impeller unit 140-T and the process-side transfer device 130 for spraying the projectile toward the foam being transferred from the process side transfer device 130 It includes a lower impeller unit (140-B) for spraying the projection material toward the foam (FO).

It further includes a pair of left and right side impeller units 140-S for spraying.

In the present invention, the upper impeller unit (140-T) and the lower impeller unit (140-B) are installed on the left and right outer portions of the foam (FO) as the center, and at this time, they are installed inclined inward to face the foam (FO). As a result, the projection material can be sprayed over the entire surface of the foam (FO).

However, further including a side impeller unit (140-S) to spray the projection material with a stronger force on the sides of the foam by spraying with a smaller spray angle from both sides of the foam (FO), foreign matter attached to the foam It is more efficient to remove.

As shown in Figure 4, a pair of upper impeller units (140-T) disposed on the upper left and right sides of the foam are placed in the front and rear directions based on the moving direction of the foam, so that they are divided into four upper impeller units (140-T). Make up a pair, as is the lower impeller unit 140-B.

Accordingly, a three-axis driver may be used as a multi-stage driver for tilting, and it is preferable to be installed in the process chamber 120 through a three-axis driver capable of angle adjustment in the X/Y/Z three-axis directions. This is also the case with the side impeller unit 140-S.

This multi-stage angle adjustment state is illustrated in FIG. 5. FIG. 5 illustrates a state in which the impeller unit 140 adjusts the tilting angles θ1, θ2, and θ3 in up and down multiple stages (eg, 3 stages) based on the X-axis direction.

As shown, if the tilting angle is adjusted in advance according to the size of the foam before shot blasting the foam, or if the tilting is continued while the foam is being transported, shot blasting the entire foam including the side of the foam having a height Is made.

Of course, the 3-axis actuator is capable of tilting in any of the X-axis, Y-axis and Z-axis directions, so if you adjust the tilting angle in multiple stages for the Y-axis and Z-axis, Shot blasting of the foam is possible without missing it.
