The object storage body 2 has a loading/unloading port 7 of a workpiece (not shown), and is housed so as to surround the object to be processed. The abrasive grain projector 3 projects the abrasive grains on the workpiece to be processed in the workpiece storage body 2 . The abrasive grain collecting mechanism 4 collects the abrasive grains projected in the workpiece storage body 2 and sends them to the abrasive grain projector 3. The wet dust collector 5 is connected from the workpiece storage body 2 through a pipe 53 which is a conduction pipe, and collects dust generated by the projection of the abrasive grains.

The object storage body 2 includes a casing 11 that is housed so as to surround the object to be processed, and a partition member 12 that partitions the inner portion of the casing 11 into two or more spaces; the spreader members 13 are respectively disposed at The spaces partitioned by the partition member 12 are used to suspend and hold the workpiece, and the driving means 14a, 14b are used to rotationally drive the partition member 12 and the spreader member 13. When the partition member 12 is set at a predetermined position in the rotational direction, the partition member 12 and the casing 11 are sealed at least by the space in which the abrasive grain projection machine 3 projects the abrasive grains. Here, the sealed system has a meaning that the dust generated by the projection in the space does not flow out to the outside of the space. When the object to be processed which is stored in a space (here, a closed space) partitioned by the partition member 12 is projected by the abrasive grain projector 3, the other space (closed space) can be used. In addition to the space, the above-described loading/unloading port 7 is provided at a position where the workpiece is carried in and out.

Specifically, as shown in FIGS. 1 to 4, the casing 11 has a wall portion composed of a front wall portion 15, a rear wall portion 16, a left side wall portion 17, and a right side wall portion 18, and has a occlusion portion. The top plate portion 19 of the upper portion of the wall portion and the bottom plate member 20 disposed opposite the top plate portion 19 below the wall portion. As shown in Fig. 4, the left half portion 16a of the rear wall portion 16 is inclined with respect to the right half portion 16b. The angle formed by the left half 16a and the right half 16b is greater than 90° and less than 180°. As shown in FIG. 2, the abrasive grain projector 3 is disposed in the left half 16a of the back wall portion 16.

By arranging the abrasive grain projector 3 in the above manner, the abrasive grain projector 3 can project the abrasive grains at an appropriate projection angle with respect to the object to be processed (refer to FIG. 4) (even if the right half 16b is inclined) ). Further, since the space of the bucket elevator 32 to be described later can be obtained on the right half 16b side of the rear wall portion 16, it is possible to reduce the size of the apparatus.

As shown in FIG. 3, the inspection door 18b is provided in the right side wall part 18. A loading/unloading port 7 is provided in the front wall portion 15. Further, the loading/unloading port 7 may be provided with a switch door that can be sealed in the casing 11. However, in the two-station system in which the scanning station S1 and the work station S2 are described here, as described later, only the scanning station S1 side may be sealed, and the working station S2 side may be opened to the outside air side at any time. In other words, since the partition member 12 seals the grinding station S1 as will be described later, an opening having the same size as the working station S2 can be provided, so that the loading and unloading port 7 can be easily attached and detached.

As shown in FIG. 4, the spacer member 12 is formed in a plurality of (two in FIG. 4) plate-like members in a plan cross section of the apparatus, and is disposed in a direction substantially perpendicular to a plan view. Each of the plate-like members is bent toward the center portion (hereinafter referred to as "the first portion 12a"), and the both side portions (hereinafter referred to as "the second portion 12b" and the "third portion 12c", respectively) are bent in the direction in which they approach each other. V shape. Further, the partition member 12 composed of a plurality of plate-like members is integrally formed in the first portion 12a so as to be symmetrical with respect to the main rotating shaft (not shown). Further, the partition member 12 is provided with a reinforcing member 12f for maintaining the predetermined strength of the second portion 12b and the third portion 12c formed in the above-described manner without deformation.

As shown in FIG. 4 and FIG. 5, a plate-shaped rubber member 12d which is slidably attached to the casing 11 to the outside is attached to the both side portions of the partition member 12, that is, the second portion 12b and the third portion 12c. On the side of the casing 11, the abutting portions 17a and 18a which are in contact with the rubber member 12d at a predetermined position in the rotational direction, and which seal the gap between the inner wall surface of the casing 11 and the partition member 12 are provided from the left side wall portion 17 And the inner surface of the right side wall portion 18 extends.

The top plate portion 19 may also be configured to rotate simultaneously with the partition member 12. Here, an example in which the top plate portion 19 is configured not to rotate will be described. A rubber member 12e is provided on the upper edge portion of the partition member 12, and the rubber member 12e is slidably coupled to the top plate portion 19, whereby the gap between the partition member 12 and the top plate portion 19 is sealed.

Further, since the partition member 12 and the bottom plate member 20 are configured to rotate together, they may be integrally formed. However, a rubber member (not shown) is also provided on the lower side of the partition member 12, and the rubber member is used for the rubber member. The lower side is also closed.

When the partition member 12 is located at a predetermined position in which the rubber member 12d abuts in the rotational direction of the abutting portions 17a, 18a, the space in which the abrasive grains can be projected by the abrasive grain projector is sealed. Hereinafter, the position S1 located in the sealed side space shown in FIG. 4 and the like is referred to as a “study station”, and the position S2 located on the side of the loading/unloading port 7 on the opposite side is referred to as a “work station”. Here, the partition member 12 has been described as an example in which the inner portion of the casing 11 is partitioned into a space which becomes the space for the inspection station S1 and two spaces which become the space of the work station S2. However, the casing 11 may be configured to be inside the casing 11. Partially separated by more than 3 spaces. Further, Rk in Fig. 4 indicates the sweeping range, and D1 indicates the direction in which the abrasive grains of the abrasive grain projector are projected.

As shown in FIG. 4, the spreader members 13 are provided in two spaces which are respectively separated by the above-described partition member 12. The spreader member 13 is composed of a column member 13a which is formed upright from the bottom plate member 20, and a hanging member 13b which is formed to extend horizontally or obliquely upward from the column member. The spreader member 13 is a jig for mounting a workpiece, and may be configured to hold and hold the object to be treated.

Here, the manner in which the spreader member 13 is provided as the object storage body 2 constituting the bead hitting device 1 will be described, but the spreader member 13 may not be provided. When the spreader member is not provided, it may be configured to provide a table member on which the workpiece is loaded. The table member may be the above-described bottom plate member 20, or may be formed by additionally adding the bottom plate member 20.

The driving means 14 is constituted by a driving means 14a for rotationally driving the partition member 12, and a driving means 14b for rotationally driving the spreader member 13. As shown in FIG. 1, the driving means 14a includes a motor 23 provided with a speed reducer provided on the base 21, a main rotating shaft (not shown) that connects the workpiece storage unit 2, and a motor 23 with a speed reducer. A timing belt (not shown) and a bearing 22 through which the main rotating shaft passes. A roller chain can also be used instead of a timing belt. The driving means 14a rotates the bottom plate member 20 and the partition member 12 of the workpiece storage body 2 by the motor 23 through the timing belt and the main rotating shaft.

On the other hand, the driving means 14b includes a rotating shaft (not shown) connected to the spreader member 13, a motor (not shown) provided with a speed reducer provided on the base 21, and a rotating shaft and a speed reducer. Motor roller chain (not shown). 14b by means of the drive train of the motor, the roller chain transmission rotating shaft and ^the spreader member 1312 to rotate independently from the partition member.

Therefore, in a state where the polishing station is sealed by the partition member 12, the abrasive grains can be projected by the abrasive grain projector 3 while rotating the workpiece attached to the spreader member 13, and a uniform polishing process can be performed.

In the object storage unit 2 of the present invention, in the polishing station S1, the abrasive grains are projected from the polishing grain projector 3 to the workpiece, and after the grinding is completed in the work station S2 from the loading/unloading port 7 which is open at any time. The object to be processed is taken out and then the object to be processed is scanned. In other words, the two-station method consisting of the grinding station S1 and the work station S2 is in parallel with the grinding process of the grinding station S1, and the workpiece can be loaded and unloaded at the working station S2.

On the other hand, the one-station bead hitting device must have the following repeated actions, that is, the door is opened, the processed object after the completion of the sweeping is taken out, and then the processed object is attached, and the door is further sealed, and then the grinding is performed. . Therefore, the two-station method of the present invention can shorten the cycle time and reduce the labor of the operator as compared with the one-station mode.

Further, in the beating device 1, a control unit 25 for controlling a driving means 14a for rotationally driving the partition member 12 is provided in the control panel 26, and the control portion 25 controls the partition member 12 by timer management. The rotation action.

In detail, after the abrasive grain projection machine 3 projects the abrasive grains, it is necessary to collect the dust remaining in the polishing station S1 by the wet dust collector 5. Therefore, when the partition member 12 is rotated immediately after the completion of the projection, the dust leaks to the side of the work station S2.

Therefore, for example, (1) the ability from the abrasive grain projector 3 and the wet dust collector 5 (including the dust collecting air volume and the volume of the sealed space of the scanning station S1), by simulation, after the projection is completed, the calculation is performed by the wet type. The dust collector 5 can sufficiently capture the time, (2) based on the simulation time, determine the actual standby time during the trial operation adjustment, and (3) input the actual standby time into the memory unit in the control unit 25, thereby It can achieve a significant reduction in dust leakage to the station S2. In addition, the standby time setting or the increase setting may be changed, and a sensor is provided in the polishing station S1. The control unit 25 controls the rotation of the partition member 12 in accordance with the output from the sensor.

As described above, the rotation operation of the partition member 12 is controlled by the timer, whereby the dust can be prevented from leaking from the polishing station S1 to the work station S2.

Moreover, in the case of the manual one-station type device, when the opening and closing door is opened due to a mistake in the grinding operation, dust leakage occurs. The rotation of the partition member 12 is controlled by a timer, whereby this problem can also be solved.

As shown in FIG. 6, the abrasive grain projector 3 includes an impeller 27, a distributor 28, and a control gauge 29. The control unit 29, which is a fixed portion, is made of beryllium copper, and does not generate a spark even if it is in contact with the impeller 27 and the distributor 28 of the rotating portion. The bead hitting device 1 provided with the control unit 29 can prevent the conventional abrasive grain projector 3 from generating a spark due to collision of metals with each other.

As shown in FIG. 3, the abrasive grain recovery mechanism 4 includes a feed conveyor 31, a bucket elevator 32, and an air separation separator 33. The feeder conveyor 31 is provided at the bottom of the beating device 1 from the front side to the back side as viewed by the operator. The bucket elevator 32 is provided along the rear wall portion 16 of the beating device 1, and is formed upright from the outlet of the feed conveyor 31. The air separation separator 33 is attached to the outlet of the bucket elevator 32 located above the bead blasting device 1, and the dust generated by the grinding of the die-cast product or the abrasive grains, the broken abrasive grains, and the oxidation are oxidized by the wind. The foreign matter such as a film or a burr, and the abrasive grains are separated, and the separated abrasive grains are induced to the abrasive grain projector 3 by an induction tube (not shown).

Here, as shown in FIG. 7, the bucket elevator 32 has a conductive nylon bucket 34 and a belt 35 for driving the bucket 34. Since the abrasive grain collecting mechanism 4 uses the conductive nylon-made bucket 34, the friction of the belt 35 can be reduced, and a structure in which the spark is not generated even if the bucket 34 comes into contact with the sleeve 36 made of iron is formed. Thereby, it is possible to prevent dust explosion caused by dust generated from the die-cast product or the abrasive grains by the sweeping.

As shown in FIG. 8, the wet dust collector 5 is provided with a blower 42 in the outlet nozzle 41, and has a water-cutting plate (excluding device) 43 and an S-shaped impeller portion 44. The dust that has flowed into the wet dust collector 5 by the blower 42 is collected by the water film 44a of the S-shaped impeller portion 44 by the washing action and the centrifugal force.

The S-shaped impeller portion 44 functions as a high-efficiency dust collecting portion by collision and centrifugal force when the dust contained in the air is intensely mixed with water. The dust collected by the S-shaped impeller portion 44 forms a slurry and is deposited on the water tank below the dust collector body 45. On the other hand, the air washed by the S-shaped impeller portion 44 is cut by the water cutting plate and discharged from the outlet nozzle 41.

In addition, in FIG. 8, the inspection caps 45c and 45d are provided in the nozzles 45a and 45b provided in the vicinity of the center part of the dust collector main-body 45. Also, the arrow indicates the direction in which the air flows.

The fan impeller (blade portion) constituting the blower 42 of the wet dust collector 5 is made of aluminum. A beating device 1 having an aluminum fan impeller prevents sparks generated by collision of metals with each other. Thereby, it is possible to prevent the dust explosion caused by the dust generated from the die-cast product or the abrasive grains by the grinding and the gas explosion generated by the reaction of the dust and the water.

Further, as shown in FIGS. 8 and 9, the wet dust collector 5 has an exhaust valve 46 provided on the upper portion of the dust collector main body 45. The exhaust valve 46 has a spring member 47 that biases the valve body 48 toward the outer side of the wet dust collector 5 (the side where the exhaust valve 46 is set to the discharge state). In the operation of the blower 42, the negative pressure resists the spring. The valve body 48 is closed by the elastic force of the member 47, and the valve body 48 is opened during the stop of the blower 42. Thereby, when the blower 42 is stopped, when the hydrogen gas is generated, the exhaust valve 46 also discharges the hydrogen gas outside the machine, and the hydrogen gas is prevented from being filled in the wet dust collector 5. Further, the spring member 47 is attached to the attachment member 46b which is disposed inside the nozzle portion 46a of the upper portion of the dust collector body 45, and the valve body 48 is biased toward the outside of the wet dust collector 5.

The beating device 1 having the exhaust valve 46 can safely sweep the die-casting product which is highly likely to cause dust explosion during the sweeping process and generate hydrogen due to the reaction of dust and water, for example, die casting of magnesium alloy and aluminum alloy. product. Further, the wet dust collector 5 of the beating device 1 is disposed outside the house, and the hydrogen gas discharged from the exhaust valve 46 can be prevented from being filled in the house.

Further, the wet dust collector 5 has a rupture plate 49 which is provided on the upper portion of the dust collector body 45, and starts to operate when the pressure in the dust collector body 45 reaches a certain level or more, and serves as an open explosion dissipating mechanism. The rupture plate 49 is made of, for example, SUS. In the event of an explosion, the plate ruptures and ruptures, whereby the blast can be dissipated and the wet dust collector 5 is prevented from being damaged. The strength of the rupture plate 49 is set to be less than or equal to 1/4 of the design compressive strength of the apparatus body.

The beating device 1 having the exhaust valve 46 and the rupture plate 49 can safely sweep and process a die-casting product which is highly likely to generate dust during the grinding process, and which generates hydrogen due to the reaction of dust and water, such as magnesium alloy and aluminum. Die-cast products made of alloy.

In addition, the explosion dissipating mechanism is not limited to the rupture plate 49, and may have, for example, a predetermined lead hammer or a door member that is normally closed by its own weight, and a hinge member that rotatably holds the door member. In the case of an explosion, a so-called hinged door type dissipating mechanism that opens a door member due to an explosion of air waves may also be used. Further, the explosion dissipating mechanism has, for example, a panel member and a fitting nozzle portion that is normally inserted and held to hold the panel member, and when an explosive gas wave is generated, the embedding of the panel member is released by an explosive gas wave, and the nozzle portion is performed. The so-called escape panel escape mechanism of the opening action is also possible. Further, the explosion-dissipating mechanism of the rupture plate 49 or the like is not limited to being provided on the upper portion of the dust collector body 45, and may be provided, for example, on the side surface portion. That is, it is provided in the piping of the nozzle of the side surface or in the piping which is connected to the nozzle and upward, thereby dissipating the explosion air wave upward.

Inside the inlet nozzle 50 of the wet dust collector 5, as shown in Fig. 8, an explosion-proof wave buffer damper 51, which is a backflow prevention valve, is provided. The explosion air surge damper 51 has a damper member 52 that is normally set to open and is closed when an explosion of a blast or the like occurs. In the case of an explosion, the damper member 52 is closed, and the damper member 52 is closed to prevent the blast from flowing into the object storage body 2 side from the wet dust collector 5.

Since the beating device 1 having the backflow prevention valve, that is, the explosion air wave damper 51, can prevent the object storage body 2 side from being damaged by the explosion air wave, it is possible to safely sweep the dust and explode during the grinding process. High-strength, and die-casting products that generate hydrogen due to the reaction of the dust with water, such as die-cast products made of magnesium alloy and aluminum alloy.

Further, the installation place of the explosion air wave damper 51 is not limited to the inside of the inlet nozzle 50 of the wet dust collector 5. For example, when it is provided between the wet dust collector 5 and the workpiece storage body 2, the object storage body 2 can be protected. The sedimentation chamber 55 can also be protected by being disposed between the wet dust collector 5 and a settling chamber 55 to be described later.

The beating device 1 includes an exhaust valve 46, a rupture plate 49, and an explosion-wave cushion damper 51, whereby the abrasive grains are projected onto a magnesium alloy or an aluminum alloy die-cast, that is, a workpiece, and the surface of the object to be processed is processed. Particularly effective. In the case of magnesium alloy die casting, the abrasive grain-based zinc-based projection material projected from the abrasive grain projector 3, and the aluminum-grained aluminum alloy projection material projected from the abrasive particle projector 3 in the case of aluminum alloy die casting.

As shown in FIG. 3, the sedimentation chamber 55 is provided in the middle of the pipings 53 of the wet dust collector 5 from the workpiece storage body 2. In addition, the arrow shown in FIG. 3 shows the flow direction of the air containing dust.

In the upper portion of the sedimentation chamber 55, an inlet 55a and an outlet 55b are provided near the object storage body 2 side and near the wet dust collector 5 side. Further, a barrier member 56 extending downward from the top plate 55c is provided inside the sedimentation chamber 55. The barrier member 56 has a function of delaying the residence time by causing the air containing the dust flowing down from the inlet 55a to flow back to the lower side and to the outlet side. Further, the barrier member 56 is disposed at a position closer to the inlet 55a than between the inlet 55a and the outlet 55b. Thereby, the flow rate of the upward flow toward the outlet 55b is slower than the flow rate of the downward flow from the inlet 55a. As a result, the air containing the dust flowing into the wet dust collector 5 is separated by the burr having a weight larger than that of the dust, and is discharged from the lower discharge port 55d.

Further, in the bead hitting device 1, not only the motor is used in a safe explosion-proof type, but also the secondary side wiring is also safely expanded. Further, in the beating device 1, the limit switch, the proximity sensor, and the like are configured via a barrier relay, and are used as a cost-effective safety explosion-proof structure. Here, the essential safety explosion-proof structure has the following meanings, that is, it is not possible to ignite an explosive gas due to a spark or a high temperature portion generated at normal time and in an accident, and is subjected to an ignition test and other confirmed structures in a public authority. Further, in the bead hitting apparatus 1, the control panel 26 may be configured to be in a dustproof structure by air pressure control panel (air purification), and since it is separately disposed from the apparatus body (study station, etc.), safety can be realized. Sweep processing.

The beading method using the above-described bead hitting device 1 will be described with reference to Figs. 2 to 4 and Fig. 8 . First, in the work station S2, the workpiece is attached to the spreader member 13. Next, the partition member 12 and the spreader member 13 are rotated around the main rotating shaft, whereby the object to be processed after installation is placed on the side of the polishing station S1, and the space on the side of the grinding station S1 is sealed. Next, in the polishing station S1, the abrasive grains are projected onto the object to be processed by the abrasive grain projector 3, and the polishing is performed. At this time, in the work station S2, the workpiece is loaded and unloaded in parallel. After the projection is stopped, the partition member 12 is allowed to stand by for a predetermined time (ventilation time). After a predetermined period of time, the partition member 12 and the spreader member 13 are rotated around the main rotating shaft, and the workpiece after the sweep processing is sent to the work station S2. The projected abrasive grains are sent to the abrasive particle projector 3 by the abrasive grain collecting mechanism 4, and the dust containing the abrasive grains is transferred to the wet dust collector 5 through the pipe 53. In the wet dust collector 5, the dust in the air is collected by the water film 44a, and the collected dust is formed into a slurry to be precipitated, and the dust-collected air is discharged from the outlet nozzle 41 by the blower 42.

Further, the dust collection by the wet dust collector 5 may be performed only during the sweeping and ventilating time, or continuously during the operation of the beating device 1.

The bead device 1 to which the present invention is applied includes the object storage body 2, the abrasive grain projector 3, the abrasive grain collecting mechanism 4, and the wet dust collector 5 as described above, whereby the possibility of dust explosion is high. The die-casting product can be safely processed for sweeping.

Further, the beating device 1 and the wet dust collector 5 are provided with an exhaust valve 46, a rupture plate 49 as an escape mechanism, and an explosion wave damper 51 as a backflow prevention valve, whereby the possibility of occurrence of dust explosion is high. And die-casting products that generate hydrogen due to the reaction of dust and water, such as magnesium alloy and die-casting products made of aluminum alloy, can be safely scanned.

Moreover, the object storage body 2 of the beating device 1 includes the casing 11, the partition member 12, the spreader member 13, and the driving means 14, and when the partition member 12 is set at a predetermined position in the rotational direction, the formation is formed. There is a so-called plural station method (in the above-described two-station method) in which at least one sealed space surrounded by the partition member 12 and the casing 11 is provided. Therefore, in one station, the other station can perform loading and unloading of the workpiece. Therefore, the cycle time can be shortened. Further, when the cycle time is the same as that of the one-station method, since two or more stations are provided, a sufficient dust collection time can be set in the station where the sweep processing is performed, and as a result, the dust removal rate can be improved. That is, the bead hitting device 1 can increase the productivity and perform detailed surface processing as compared with the one-station grinding device. Further, since the bead hitting device 1 is configured to control the rotation of the partition member 12 by the control unit, it is possible to reduce the leakage of dust from the polishing station to the work station.

Further, in the bead hitting device 1, in order to prevent heat generation due to friction or friction between the irons, a non-ferrous material is appropriately selected. Since the material for preventing spark generation is used for the fan impeller of the control unit 29, the bucket 34 of the bucket elevator 32, and the blower 42, for example, the function of the apparatus is not impaired, and the safe sweeping process can be performed. Further, since the wet dust collector 5 can minimize the damage of the explosion, the working environment of the operator can be improved, and the grinding process can be performed safely.
