By the way, the work work apparatus of Patent Document 1 has the following problems.
In the work work apparatus of Patent Document 1, the lifting and lowering operation of the partition plate and the rotational movement and rotation operation of the table are performed alternately. That is, the three cylinder devices that drive the partition plate and the one drive motor that drives the table are alternately driven. For this reason, while one of the three cylinder devices and one drive motor is driven, the other is in a stopped state, and a stop time occurs alternately between the cylinder device and the drive motor. Therefore, within the operation time of the work work device, the drive time of each drive source is relatively short, and the individual operation efficiency of each drive source is low.

  The present invention has been made in view of the above-described background, and an object of the present invention is to provide a work work device that can effectively use a drive source and increase its operating efficiency.

One aspect of the present invention is a work work apparatus in which a plurality of work parts that perform work on the work including a carry-in / out part for carrying in and out the work are arranged on a circumference centered on a reference axis. There,
A table unit provided with a plurality of tables arranged corresponding to the plurality of working units and rotatably provided around the reference axis;
A partition unit that partitions the plurality of working units, and is provided so as to be movable up and down in a direction along the reference axis;
One driving motor for generating a driving force for rotating the table unit and raising and lowering the partition unit;
A drive shaft that is disposed on the reference axis and rotates with the rotation of the drive motor;

A work working apparatus having a second transmission device (claim 1).

  In the work work device, two different operations, that is, the rotation operation of the table unit and the lifting / lowering operation of the partition unit can be realized by the rotation operation of one drive motor. Therefore, the drive motor is driven when performing either the rotation operation of the table unit or the lifting / lowering operation of the partition unit. Therefore, many operations in the work work device can be performed by the drive motor, the stop time can be reduced, and the operation time of the drive motor itself can be increased. Thereby, the operating efficiency of the drive motor can be increased.

  Further, by switching between the partition connection state, the partition connection release state, the table connection state, and the table connection release state, the movement of the work placed on the table between the working units is adjacent. The work can be performed in a state where the working parts are partitioned by the partitioning part. Thereby, while moving the said workpiece | work between the said working parts easily, it can prevent easily that each working part influences each other.

(Claim 4).

  For example, in order to securely hold the workpiece in the working unit, a part of the workpiece may be inserted and arranged in the reference axis direction in the workpiece holding unit provided in the working unit. At this time, when the workpiece is transferred to the adjacent working unit, the workpiece needs to be moved in the reference axis direction and separated from the workpiece holding unit. Even in such a case, as described above, the workpiece can be easily transferred by changing the workpiece by the workpiece engaging portion and the workpiece holding portion.

  2. Description of the Related Art Conventionally, as a method for cleaning and drying a workpiece, a method is often used in which a cleaning liquid is discharged onto a workpiece for cleaning and then the workpiece is dried by blowing dry air onto the workpiece in a drying section. The drying air in the drying section often uses factory air that is used throughout the factory. Factory air is always supplied by a large compressor that consumes a large amount of power, and a reduction in the amount of use is desired from the viewpoint of environmental impact.

In the cleaning unit, when the cleaning liquid is discharged onto the workpiece, the cleaning liquid becomes a cleaning liquid mist composed of minute water droplets. If the exhaust air containing the cleaning liquid mist is released into the factory, problems such as poor visibility and floor slipping may occur. In addition, when exhaust air is discharged outdoors, there is a risk of adverse effects on the environment. Therefore, it is necessary to separate the cleaning liquid mist from the exhaust air by an exhaust device equipped with an exhaust fan and a filter.
As described above, since both factory air and an exhaust fan are used when cleaning and drying a workpiece, power consumption is likely to increase, and reduction thereof is desired.

The exhaust circulation device has the suction path including the blower and the moisture removal passage.
The suction path is connected to the suction port of the blower, and by operating the blower port, exhaust air including mist that is minute water droplets such as cleaning liquid generated in the cleaning operation of the cleaning unit can be circulated. It is configured. The suction path is provided with the moisture removal flow path, and in the moisture removal flow path, turbulence of airflow occurs when the flowing exhaust air and the air flowing in from the atmospheric opening are mixed. To do.

  Due to the turbulence of the air current, the mist that has received a force in a direction intersecting the traveling direction in the moisture removal channel collides with and adheres to the inner wall of the moisture removal channel. And if the mist adhering to the inner wall of the said moisture removal flow path aggregates, it will flow down with dead weight and will be discharged | emitted from the said water discharge port. The dry air from which the mist has been removed from the exhaust air is sucked from the suction port of the blower, then discharged from the discharge port, and supplied to the air nozzle of the drying unit.

  Thus, according to the exhaust circulation device, exhaust air and dry air are circulated through the discharge path and the suction path by one air blower, and the mist generated in the cleaning unit is prevented from flowing out. be able to. Therefore, it is not necessary to use factory air that has been conventionally used for drying, and power consumption for use of factory air and exhaust fans can be reduced. Thereby, reduction of power consumption and environmental load is attained.

  The moisture removal flow path is connected to the upstream side of the suction path so that the axial direction is substantially horizontal, and connected to the downstream side of the upstream pipe, so that the axial direction is substantially vertical. And a downstream pipe arranged, and the water outlet may be provided at the lower end of the downstream pipe.

  In this case, when the exhaust air containing mist generated in the cleaning section flows from the upstream pipe to the downstream pipe, the flow direction can be changed. Mist has a large inertial force because it has a larger mass than air. Therefore, the mist cannot follow the change in the flow direction and collides with and adheres to the inner wall of the downstream pipe. And the mist which aggregated in the inner wall of the said downstream piping falls with dead weight, and is discharged | emitted from the said water | moisture-content discharge port distribute | arranged to the lower end of the said downstream piping. Thereby, the mist contained in exhaust air can be removed more efficiently and discharged easily.

  The exhaust circulation device may have a branch suction path that merges with the suction path, and the branch suction path may be in communication with a drying-side discharge port that opens inside the drying unit (claim). Item 12). In this case, even if mist is generated in the drying section, it can be removed. Thereby, the outflow of mist can be prevented more reliably. In addition, it is preferable that the said branch suction path merges upstream from the said moisture removal flow path in the said suction path. In this case, the mist can be more reliably removed by circulating through the moisture removal channel.

  When the engaging portion 39 of the partition unit 3 that descends comes into contact with the engaging surface 411 disposed on the table fixing portion 41 of the table unit 4, it works in conjunction with the partition unit 3 against the urging force of the urging means 427. The table unit 4 is lowered. At this time, when the table unit 4 is in the raised position, the workpiece engaging portion 402 disposed above the workpiece holding portion 24 is lowered, and between the workpiece holding portion 24 and the workpiece engaging portion 402. The relative position in the height direction changes. The workpiece 9 arranged in the workpiece engaging portion 402 is lowered together with the table 40, transferred to the workpiece holding portion 24 arranged above the workpiece engaging portion 402, and held by the workpiece holding portion 24. .

  When the lower position sensor detects that the partition unit 3 has been lowered to its lowered position, the engaging portion 52 attached to the lower side of the partition fixing plate 31 is engaged with the engaging surface 412 on the upper surface of the clutch fixing plate 358. Accordingly, the rotation of the drive motor 5 stops, and the partition unit 3 and the table unit 4 interlocked with the partition unit 3 stop at the lowered position. Then, after the energization to the first brake part 37 is stopped and the partition unit 3 is braked, the energization to the first clutch part 35 is stopped and the transmission between the drive shaft 51 and the screw shaft 361 is released. The connection is released.

Next, as shown in FIGS. 5 and 8, the work 9 is rotated, and the work 9 is cleaned and dried in the cleaning unit 22 and the drying unit 23.
By energizing the third clutch portion 61 of the third transmission device 6, the drive shaft 51 and the main rotor 62 are connected to rotate the drive motor 5 in the forward and reverse directions. As a result, the rotating operation of the drive shaft 51 is brought into a holding unit connection state in which the rotating operation of the work holding unit 24 disposed in the cleaning unit 22 and the drying unit 23 is transmitted. Then, the third brake unit 65 is energized to release the brake of the work rotation shaft 242, and the drive motor 5 is rotated in the forward and reverse directions.

  The rotational motion transmitted from the drive shaft 51 to the main rotating body 62 is transmitted to the sub rotating body 63 disposed in the cleaning unit 22 and the drying unit 23 via the transmission band 64 and is transmitted via the work rotating shaft 242. The work holding unit 24 is rotated. Thereby, the work 9 held by the work holding unit 24 is rotated. At this time, in the cleaning unit 22, the cleaning liquid is discharged from the upper cleaning nozzle 32 and the lower cleaning nozzle 224 toward the work 9 to clean the work 9. In the drying section 23, the dry air is discharged from the upper air nozzle 33 and the lower air nozzle 234 toward the work 9, and the work 9 is dried.

When the cleaning and drying of the workpiece 9 are completed in the cleaning unit 22 and the drying unit 23, the energization to the third clutch unit 61 is stopped, and the workpieces arranged in the cleaning unit 22 and the drying unit 23 for rotating the drive shaft 51 are held. The holding part connection release state in which the transmission to the part 24 is released is set. Then, the power supply to the third brake unit 65 is stopped, and the work rotation shaft 242 is braked.
The above operation is repeated to clean and dry the workpiece 9.

  As described above, in the work work device 1 shown in this example, by using the first transmission device 34, the second transmission device 43, the table lifting mechanism portion 42, the first brake portion 37, and the second brake portion 44, At least two different operations, that is, the rotation operation of the table unit 4 and the lifting / lowering operation of the partition unit 3 can be realized by the rotation operation of one drive motor 5. Therefore, the drive motor 5 is driven when performing either the rotation operation of the table unit 4 or the lifting / lowering operation of the partition unit 3. Therefore, many operations in the work work device 1 can be performed by the drive motor 5, the stop time can be reduced, and the operation time of the drive motor 5 itself can be increased. Thereby, the operating efficiency of the drive motor 5 can be increased.

  Further, the work work device 1 includes a third transmission device 6, and the above-described two operations and the rotation operation of the workpiece 9 can be realized by the rotation operation of one drive motor 5. Thereby, it is possible to further reduce the stop time and increase the operation time of the drive motor 5 itself. Thereby, the operating efficiency of the drive motor 5 can be made higher.

  Further, by switching between the partition connection state, the partition connection release state, the table connection state, and the table connection release state, the movement of each work part of the work 9 placed on the table 40 can be performed and between the adjacent work parts. It is possible to carry out the work in a state of being partitioned by the partition portion 30.

Further, below the table 40, a lid body 25 is disposed to cover the opening end portion 303 that opens downward in the partition portion 30. Then, by lowering the partition unit 3, the opening end 303 of the partition portion 30 is covered with the outer frame portion 401 and the lid body 25 of the table 40, and the workpiece 9 is covered with the partition portion 30, the outer frame portion 401 and the lid body 25. It is configured to be included. Therefore, the working parts can be more reliably partitioned. Thereby, it can prevent more reliably that each working part influences each other. In this example, the work 9 is included by the partition portion 30, the outer frame portion 401, and the lid body 25. However, the work 9 can be configured to be included by the two parts of the partition portion 30 and the lid body 25. .

The movement from the raised position to the lowered position against the urging force of the urging means 427 of the table unit 4 is performed when the partition unit 3 and the table unit 4 are engaged when the partition unit 3 is lowered. 3 is implemented in conjunction with the movement of 3. The table 40 includes a work engaging portion 402 that engages and holds the work 9 and an outer frame portion 401 that is formed so as to penetrate in the reference axis direction. Each working unit includes a workpiece holding unit 24 that holds the workpiece 9 at a position corresponding to the outer frame unit 401. As the table unit 4 moves up and down between the raised position and the lowered position, the relative position in the height direction between the workpiece engaging portion 402 and the workpiece holding portion 24 changes, and the workpiece engaging portion 402 and the workpiece holding portion 24 are changed. The workpiece 9 can be transferred between the two. When the table unit 4 is in the raised position, the workpiece 9 is engaged and held by the workpiece engaging portion 402 of the table 40, and when the table unit 4 is in the lowered position, the workpiece 9 is held by the workpiece holding portion 24. It is configured.

  In order to securely hold the workpiece 9 in the working unit, a part of the workpiece 9 is inserted and arranged in the reference axis direction in the workpiece holding unit 24 provided in the working unit. At this time, when the workpiece 9 is transferred to the adjacent working unit, the workpiece 9 needs to be moved in the reference axis direction and separated from the workpiece holding unit 24.

(Example 2)
This example shows an example in which an exhaust circulation device is provided in the work work device in the first embodiment.
As shown in FIG. 19, the exhaust circulation device 100 includes a blower 11 configured to be able to suck and discharge air, a discharge path 12 and a suction path 13 connected to the blower 11, and a branch suction path 18 that joins the suction path 13. And have.

  As shown in FIG. 19, the blower 11 in this example includes a ring blower and includes a suction port 111 that sucks air and a discharge port 112 that discharges air. The air sucked from the suction port 111 is carried to the discharge port 112 by a rotary impeller (not shown). At this time, the pressure rises due to the centrifugal force applied to the air, and high-pressure air is discharged from the discharge port 112. .

  As shown in FIG. 19, one end of the discharge path 12 is connected to the discharge port 112 of the blower 11, and the other end is connected to the air nozzle of the drying unit 23 via the discharge side branch pipe 121. The discharge path 12 is branched into an upper discharge pipe 122 and a lower discharge pipe 123 by a discharge side branch pipe 121. The upper discharge pipe 122 is connected to the upper air nozzle 33 in the drying unit 23, and the lower discharge pipe 123 is a drying unit. 23 is connected to the lower air nozzle 234.

  As shown in FIG. 19, one end of the suction path 13 is connected to the suction port 111 of the blower 11, and the other end is connected to the cleaning-side exhaust hole 221 opened inside the cleaning unit 22. The suction path 13 is configured to be able to circulate the exhaust air A1 including mist composed of minute water droplets such as cleaning liquid generated in the cleaning unit 22, and removes moisture that separates the exhaust air A1 into dry air A2 and mist. A flow path 130 is provided.

  The cleaning-side exhaust hole 221 is formed through the upper surface of the partition part 30 in the cleaning part 22 and is connected to one end of the exhaust pipe 131 that constitutes the suction path 13. The exhaust pipe 131 is curved after going upward from the cleaning side exhaust hole 221, and the other end side of the exhaust pipe 131 is arranged to hang downward.

As shown in FIG. 19, the other end of the exhaust pipe 131 is connected to the moisture removal channel 130.
The moisture removal channel 130 includes an atmosphere opening 14 that is open to the atmosphere, a moisture discharge port 15 that discharges moisture, and an upstream pipe 16 that is disposed on the upstream side of the suction path 13 so that the axial direction is substantially horizontal. And a downstream pipe 17 arranged so that the axial direction is substantially vertical.

  As shown in FIG. 19, the air opening 14 that is opened to the atmosphere is formed in an air introduction pipe 141 that is disposed below the exhaust pipe 131 and is opposed to the other end. The air introduction pipe 141 is arranged so that the axial direction thereof is substantially vertical, and an air opening 14 is formed at the lower end thereof. The atmospheric opening 14 is provided with a valve 142 whose opening area can be adjusted.

As shown in FIG. 19, the upstream pipe 16 is arranged at a portion where the exhaust pipe 131 and the air introduction pipe 141 join. The upstream pipe 16 is arranged so that its axial direction is substantially horizontal.
A downstream pipe 17 is disposed at the downstream end of the upstream pipe 16. The downstream pipe 17 has an upper downstream pipe 171 erected upward from the downstream end portion of the upstream pipe 16 and a lower downstream pipe 172 hanging downward from the downstream end portion of the upstream pipe 16.

The lower downstream pipe 172 includes a tapered portion 173 that gradually decreases in diameter downward, and a drain pipe 174 that extends downward from the tip of the tapered portion 173, and is provided at the lower end of the drain pipe 174. Is formed with a water outlet 15 for discharging water.
At the upper end of the upper / downstream pipe 171, there is a connection pipe 132 connected to the suction port 111 of the blower 11 and a branch suction path 18 communicating with the drying section 23.

  As shown in FIG. 19, the branch suction path 18 that joins the suction path 13 has one end connected to a drying side exhaust port 235 formed through the upper surface of the partition part 30 of the drying unit 23, and the other end connected to the upper downstream pipe 171. It is connected to the upper end of the. One end connected to the drying side exhaust port 235 is arranged upward, and the other end connected to the upper downstream pipe 171 is arranged downward. Since the amount of mist generated in the drying unit 23 is smaller than that in the cleaning unit 22, in this example, the suction path 13 and the branch suction path 18 are merged on the downstream side of the moisture removal channel 130. However, it is more preferable to join the branched suction path 18 on the upstream side of the moisture removal channel 130.

  In the exhaust circulation device 100 configured as described above, when the blower 11 is operated, air is sucked from the suction port 111, and the exhaust air A <b> 1 including mist generated in the cleaning unit 22 flows into the suction path 13. The exhaust air A <b> 1 circulates to the moisture removal flow path 130 via the exhaust pipe 131.

  In the moisture removal channel 130, the atmosphere A 3 is introduced from the atmosphere opening 14 through the atmosphere introduction pipe 141, and mixed with the exhaust air A 1 inside the upstream pipe 16, and the turbulence of the air flow occurs inside the upstream pipe 16. Due to the turbulence of the air flow, the mist that receives the force applied in the direction intersecting the traveling direction in the moisture removal channel 130 collides with and adheres to the inner wall of the moisture removal channel 130. Then, when the mist adhering to the inner wall of the moisture removal flow path 130 aggregates, it flows down by its own weight and is discharged from the moisture discharge port 15. The dry air A2 from which the mist has been removed from the exhaust air A1 is sucked from the suction port 111 of the blower 11, is then discharged from the discharge port 112, and is supplied to the air nozzle of the drying unit 23.

  As described above, according to the exhaust circulation device 100, the exhaust air A1 and the dry air A2 are circulated through the discharge path 12 and the suction path 13 by one blower 11, and the mist generated in the cleaning unit 22 is discharged. Can be prevented. Therefore, it is not necessary to use the factory air that has been conventionally used for drying, and it is possible to reduce power consumption required for using the factory air and the exhaust fan. Thereby, reduction of power consumption and environmental load is attained.

  In addition, the moisture removal flow path 130 is connected to the upstream side of the upstream side of the suction path 13 so that the axial direction is substantially horizontal, and is connected to the downstream side of the upstream pipe 16 so that the axial direction is substantially vertical. The downstream pipe 17 is provided with a moisture outlet 15 at the lower end of the downstream pipe 17.

  Therefore, when the exhaust air A <b> 1 containing mist generated in the cleaning unit 22 flows from the upstream pipe 16 to the downstream pipe 17, the flow direction can be changed. Mist has a large inertial force because it has a larger mass than air. Therefore, the mist cannot follow the change in the flow direction and collides with and adheres to the inner wall of the downstream pipe 17. The mist aggregated on the inner wall of the downstream pipe 17 falls due to its own weight and is discharged from the moisture discharge port 15 disposed at the lower end of the downstream pipe 17. Thereby, the mist contained in the exhaust air A1 can be more efficiently removed and easily discharged.

  Further, the exhaust circulation device 100 has a branch suction path 18 that joins the suction path 13, and the branch suction path 18 communicates with a drying side exhaust port 235 that opens inside the drying unit 23. Therefore, even if mist is generated in the drying unit 23, it can be removed. In this example, a part of the mist included in the exhaust air A <b> 1 flowing through the branch suction path 18 adheres to the inner wall of the branch suction path 18. The mist remaining in the exhaust air A1 after passing through the branch suction path 18 falls below the downstream pipe 17 and is discharged from the moisture discharge port 15 when the flow direction changes from the branch suction path 18 to the connection pipe 132. Is done. Thus, the exhaust air A1 from which the mist has been removed flows into the connection pipe as dry air A2. Thereby, the outflow of mist can be prevented more reliably.

  The exhaust gas circulation device shown in this example is not limited to use in the work work device shown in the first embodiment, and can be used in various devices having a cleaning unit and a drying unit.

  Further, in this example, the branch suction path 18 communicated with the drying unit 23 is provided. However, when the amount of mist generated in the drying unit 23 is so small that it does not adversely affect the environment, as shown in FIG. The suction path 18 may be omitted.
