Description

  The present invention relates to a workpiece processing apparatus that performs processing such as cleaning while feeding various workpieces using a rotating drum having a configuration in which workpiece feeding fins are spirally arranged on the inner peripheral surface, and a workpiece using the workpiece processing device The present invention relates to a cleaning method.

  In a workpiece cleaning apparatus using a rotating drum provided with a spiral workpiece feed fin, a workpiece is cleaned by spraying a cleaning liquid from a cleaning liquid spray nozzle onto the workpiece fed by the workpiece feed fin. Patent Document 1 discloses a cleaning device having this structure. In addition, there is also known one that cleans a work passing through the cleaning liquid by feeding the work in a state where the lower part of the rotating drum provided with the work feeding fins is immersed in the cleaning liquid. Patent Document 2 discloses a cleaning device having this structure.

In a conventional cleaning apparatus using a rotating drum provided with a spiral workpiece feed fin, the workpiece to be cleaned is spiral with the lower portion of the rotating drum directed in the direction of its central axis as the rotating drum rotates. It is sent out by the work feed fin. Therefore, the work posture in the rotating drum remains substantially constant. Therefore, in order to spray the cleaning liquid on the entire workpiece, the cleaning liquid is sprayed from above and below the workpiece. Alternatively, the direction of spraying the cleaning liquid is switched. When the work is immersed in the cleaning liquid, the rotary drum is rotated in the forward and reverse directions to swing the work so that the cleaning liquid contacts the entire work.

  However, in the conventional method, there are many cases where the cleaning liquid cannot be reliably sprayed or brought into contact with the entire workpiece. Further, in the case of a work made of a soft material, there is a high possibility that the surface of the work will come into contact with another work, the inner peripheral surface of the rotary drum, or the feed fin by rotating the rotary drum forward and backward.

  In view of these points, an object of the present invention is to provide a work processing apparatus that performs a process such as cleaning a work using a rotating drum having a spiral feed fin. It is to make it possible to reliably perform the process.

  Also, in a work processing apparatus using a rotating drum provided with a spiral feed fin, it is possible to reliably perform processing such as cleaning of a work made of a soft material without damaging the work. It is in.

In order to solve the above problems, the present invention is a rotation module suitable for use in a workpiece processing apparatus for performing workpiece cleaning and the like,

A plurality of workpiece feed fins arranged spirally along the inner peripheral surface of the rotating drum;
Each work feed fin has a length corresponding to one or more circumferences of the inner peripheral surface of the rotating drum at a predetermined lead pitch, and is arranged adjacent to the rear end of the work feed fin on the upstream side in the work feed direction. The front end in the work feed direction of the work feed fin on the downstream side is arranged so as to be in a position retracted to the work insertion port side,
When the rotating drum is rotated around the central axis in the first rotational direction, the workpieces fed from the workpiece insertion port are fed out in the direction of the central axis by the workpiece feeding fins and sequentially delivered to the subsequent workpiece feeding fins. It comes to be discharged from the outlet,
Between the rear end of each work feed fin and the front end of each downstream work feed fin adjacent to this, there is a work catching pocket that opens in the direction in which the downstream work feed fin extends. Each is arranged,
Work guide step portions are arranged on the inner peripheral surface portion of the rotating drum where the work is handed over from the rear end of each work feed fin to each work feed fin side on the downstream side,
When the rotating drum rotates in the second rotation direction opposite to the first rotation direction after the work is passed from the work feed fin to the downstream work feed fin over the work guide stepped portion, the work guide step difference It is characterized in that the workpiece is guided along the portion to the workpiece catching pocket and caught in the workpiece catching pocket.

  Here, when the rotary module is used for cleaning or drying a workpiece, the rotary drum is formed of a porous material, and the work catching pocket has a plurality of vents or liquids. It is sufficient to form a hole or opening.

Next, the work processing apparatus of the present invention includes:
A rotation module configured as described above;
A support portion horizontally supporting the rotating drum in a state of being rotatable around a central axis;
A rotational drive unit for rotationally driving the rotary drum around a central axis;

A rotational position detector for detecting the rotational position of the rotating drum;
And a control unit that controls the rotation driving of the rotating drum by the rotation driving unit and the fluid spraying operation by the fluid spraying unit based on the detection result of the rotation position detecting unit. It is said.

  Here, when the work processing apparatus is used as a work cleaning apparatus, the fluid spraying section may be a cleaning liquid spraying section. When used as a work drying device, a drying air blowing section or a dryer for blowing hot air may be used.

  In addition, the cleaning liquid spraying section can change the spraying direction of the cleaning liquid. Furthermore, the cleaning liquid spraying section may be configured to spray the cleaning liquid from the outside and inside of the rotating drum toward the workpiece catching pocket.

Next, a workpiece cleaning method using the workpiece processing apparatus of this configuration is:
A workpiece loading step of loading a workpiece from the workpiece loading port in a state of a rotation angle position of the rotating drum where the pocket for workpiece capture is at the lowest position;
The rotary drum is rotated in the first rotation direction over an angular range of one or more rounds, and the work is moved from the work feed fin on the upstream side in the work feed direction to the work guide on the downstream side over the work guide step. A workpiece feeding process to be delivered to the feeding fin;

A workpiece discharging step of rotating the rotating drum in a first rotation direction and transferring the workpiece captured in the workpiece capturing pocket to a workpiece feeding fin on the downstream side.

  Here, in order to increase the cleaning efficiency of the workpiece, it is desirable to intermittently spray the cleaning liquid in the workpiece cleaning step. In addition, it is desirable to change at least one of the rotational speed of the rotating drum, the spray angle of the cleaning liquid, and the spray amount of the cleaning liquid in the work cleaning process according to the work to be cleaned.

  In the rotating module according to the present invention, the rotating drum is rotated in the first rotating direction so that the workpiece is fed from the workpiece feeding fin on the upstream side in the workpiece feeding direction over the workpiece guide stepped portion. Can be handed over to the fin. After that, when the rotary drum is rotated in the reverse direction (rotated in the second rotation direction), the work is guided to the work catching pocket along the work guide stepped portion and is caught there. By rotating the rotating drum in the second rotation direction after capturing the workpiece in the workpiece capturing pocket, the workpiece can be pulled upward from the lowest position of the rotating drum. Cleaning liquid or the like can be sprayed onto the workpiece while rotating the rotating drum forward and backward repeatedly within an angle range in which the workpiece is not discharged from the workpiece catching pocket.

  Therefore, unlike the conventional case where the workpiece is washed while being fed in the state where it stays at the lowest position of the rotating drum, the workpiece captured in the workpiece catching pocket is accompanied by the rotation of the rotating drum. The attitude changes greatly. Therefore, a cleaning liquid or the like can be sprayed on the entire workpiece, and processing such as cleaning of the workpiece can be reliably performed.

  Also, in the case of workpieces made of soft materials, the workpieces can be damaged if they are loaded one by one, captured one by one in the workpiece catching pocket, and then cleaned. Can be surely prevented.

  Below, with reference to drawings, the example of the workpiece | work washing apparatus to which this invention is applied is demonstrated.

Compressed air is supplied from the compressed air source 80 to the air supply pipes 75 and 78.

(Rotation module)
FIG. 2 is a perspective view of the rotating module 4 as viewed from the workpiece insertion port side. As described above, the rotating module 4 includes the rotating drum 3 having one end serving as a work insertion port 11 and the other end serving as a work discharge port 13. The rotating drum 3 is made of a porous material such as punching metal in which a large number of circular holes are formed. A plurality of workpiece feed fins 21, 22, 23... Are spirally arranged along the inner peripheral surface 31 of the rotating drum 3. Each of the workpiece feed fins 21, 22, 23,... Is formed one round along the inner circumferential surface 31 of the rotary drum 3 with a constant lead pitch. When the rotary drum 3 is rotated around the central axis 3a in the first rotational direction CCW, the workpiece W introduced from the workpiece insertion port 11 is sent out in the direction of the central axis 3a by the workpiece feeding fins 21, 22, 23. .. Are sequentially delivered to the subsequent work feed fins 22, 23, 24... And discharged from the work discharge port 13.

  Here, the work feed fins 21, 22, 23,... Are arranged as follows. In the two work feed fins arranged adjacent to each other, for example, the work feed fins 21 and 22, the work on the downstream side with respect to the rear end 21 b in the work feed direction of the work feed fin 21 on the upstream side in the work feed direction. The front end 22a of the feed fin 22 in the workpiece feeding direction starts from a position retracted by a certain amount in the direction opposite to the workpiece feeding direction.

  In addition, the workpiece catching is opened between the rear end 21b of the upstream workpiece feed fin 21 and the front end 22a of the downstream workpiece feed fin 22 in the direction in which the downstream workpiece feed fin 22 extends. A pocket 40 is disposed. A work guide stepped portion 50 is disposed along the inner peripheral surface 31 of the rotary drum 3 from the end of the opening 41 of the work catching pocket 40 on the side in the work feeding direction. After the workpiece W is transferred from the upstream workpiece feed fin 21 to the downstream workpiece feed fin 22 over the workpiece guide step 50, the rotary drum 3 is rotated in the second rotational direction opposite to the first rotational direction CCW. When rotated to CW, the work W is guided to the work catching pocket 40 along the work guide stepped portion 50 and is caught in this.

  The workpiece catching pocket 40 and the workpiece guide stepped portion 50 are similarly arranged between adjacent workpiece feeding fins.

  FIG. 3 is an explanatory view showing a feed state of the work W by the work feed fin accompanying the rotation of the rotary drum 3, FIG. 4 is an explanatory view showing an enlarged portion of the work catching pocket 40, and FIG. FIG. 3 is a plan development view showing a state where an inner peripheral surface 31 of the rotary drum 3 is developed on a plane. With reference to these drawings, the movement state of the workpiece W accompanying the rotation of the rotary drum 3 will be described.

  First, as shown in FIG. 3, the workpiece W is thrown into the rotary drum 3 from the workpiece slot 11 at the rotation angle position where the workpiece catching pocket 40 is at the lowest position of the rotary drum 3. In this rotational angle position, the front end 21a of the work feed fin 21 on the most upstream side is at the lowest angular position in the circular cross section of the rotary drum. The rotating drum 3 is formed by rounding a punching metal or the like having a constant thickness into a cylindrical shape, and the joint portion 32 is overlapped with a constant width.

  When the rotating drum 3 is turned in the first rotation direction CCW from this state, the workpiece W is sent out toward the workpiece discharge side by the workpiece feeding fin 21. As a result, the workpiece W relatively moves along the inner peripheral surface 31 as indicated by an arrow in FIG. When the rotating drum 3 rotates one or more times, the workpiece W is detached from the rear end 21b of the workpiece feeding fin 21, passes over the workpiece guide stepped portion 50, and is delivered to the front end 22a side of the workpiece feeding fin 22.

  Here, as can be seen from FIG. 4, between the rear end 21 b of the work feed fin 21 and the front end 23 a of the work feed fin 23 arranged adjacently, the joint portion 32 of the inner peripheral surface 31 of the rotary drum 3 is provided. A trapezoidal guide plate 51 is disposed along the inner peripheral surface 31 of the rotating drum in a state of filling the step. Between the end of the guide plate 51 in the workpiece moving direction and the inner peripheral surface 31 of the rotary drum is a workpiece guide stepped portion 50 facing the workpiece feed fin 22 side. The work guide step portion 50 extends from the end 42 in the work feed direction of the opening 41 of the work catching pocket 40 to the work feed fin 23.

  After the rotary drum 3 is rotated to the position where the workpiece W contacts the workpiece feed fin 22, and then the rotary drum 3 is rotated in the reverse second rotation direction CW, the workpiece W is relatively rotated in the opposite direction to the inner periphery of the rotary drum. It moves along the surface 31 and hits the work guide step 50. After that, the workpiece is guided by the work guide stepped portion 50 and moves to the opening 41 of the workpiece catching pocket 40, and enters the workpiece catching pocket 40 from the opening 41. In this way, the workpiece W is captured in the workpiece capturing pocket 40.

  In this example, by fixing a unit composed of an arcuate mounting frame 43 and three pins 44, 45, 46 fixed to the tip end portion in a cantilevered manner to the inner peripheral surface 31 of the rotating drum, A workpiece catching pocket 40 is formed between the unit and the front end 22 a of the workpiece feeding fin 22. Between the pins 44 to 46 is an opening, and the cleaning liquid can be sprayed from the outside to the workpiece W captured in the workpiece capturing pocket 40.

  After the workpiece W is captured in the workpiece capturing pocket 40, for example, the state in which the workpiece W is captured in the workpiece capturing pocket 40 can be maintained even if the workpiece W is rotated to the position shown in FIG. Thereafter, when the rotary drum 3 is rotated in the first rotational direction CCW, the opening 41 of the workpiece catching pocket 40 faces downward, the workpiece W is discharged therefrom, and is again delivered to the workpiece feed fin 22 side. . Thereafter, the work W is fed by the work feed fins 22 by rotating the rotary drum 3 in the same direction.

(Workpiece cleaning operation)
Next, FIG. 6 is a process diagram showing an example of a workpiece cleaning operation by the workpiece cleaning apparatus 1 having this configuration. First, as shown in ST1 of FIG. 6, the position A1 where the workpiece catching pocket 40 is rotated in the second rotation direction CW by 90 degrees from the lowest angular position in the circular cross section of the rotary drum 3 is the position of the rotary drum 3. Assume that it is the initial position. The rotating drum 3 is rotated 90 degrees in the first rotation direction CCW from the rotation angle position A1, and the workpiece catching pocket 40 is set to the rotation angle position A2 which is the lowest position in the circular cross section of the rotation drum 3, and this state Then, the workpiece W (1) is loaded from the workpiece loading slot 11 (ST2: workpiece loading step, workpiece position W1 in FIG. 5).

  Next, the rotating drum 3 is rotated in the first rotational direction CCW over an angular range of one or more rounds, and the workpiece W (1) is moved from the workpiece feeding fin 21 upstream in the workpiece feeding direction to the workpiece guide stepped portion. The rotation angle position A3 is passed over 50 to the downstream work feed fin 22 (ST3: work feed process, work position W2 in FIGS. 4 and 5).

  Thereafter, the rotating drum 3 is rotated in the second rotation direction CW. As a result, the workpiece W (1) after being delivered to the downstream workpiece feed fin 22 hits the workpiece guide step portion 50, and the opening portion of the workpiece catching pocket 40 along this workpiece guide step portion 50. 41 and is caught in the workpiece catching pocket 40 (ST4: workpiece catching step, workpiece positions W3 and W4 in FIGS. 4 and 5).

  After the workpiece W (1) is captured, the rotary drum 3 is moved in the first and second rotational directions within the range of the angular position where the state in which the workpiece W (1) is captured in the workpiece capturing pocket 40 is maintained. The cleaning liquid is sprayed onto the work W captured in the work capturing pocket 40 by the cleaning liquid spraying unit 7 (ST5: work cleaning process). For example, the cleaning liquid is sprayed intermittently.

  After the cleaning, a work discharging process is performed in which the rotating drum 3 is rotated in the first rotational direction CCW, and the work W (1) captured in the work capturing pocket 40 is transferred again to the work feed fins 22 on the downstream side. When the workpiece W (2) is continuously loaded and the cleaning operation is performed, a new workpiece W (2) is loaded in the process ST6 of FIG. 6 and the process returns to the process ST3 to rotate the rotating drum 3 in the same direction. Turn above.

  As a result, the workpieces W (1) and W (2) are delivered to the downstream workpiece feed fins 22 and 23, respectively. By repeating the above steps ST3 to ST6, the workpieces W can be sequentially loaded, and the workpieces W (1) and W (2) can be captured and cleaned by the workpiece capture pockets 40. The workpiece W that has been repeatedly cleaned in this manner is sent out from the workpiece discharge port 13 to the workpiece discharge chute 14 by the most downstream workpiece feed fin, and is discharged from here to a workpiece collection section (not shown).

  In order to increase the cleaning efficiency of the workpiece, parameters such as the rotational speed of the rotating drum 3 in the workpiece cleaning process, the number of repeated forward and reverse rotations, the spray angle of the cleaning liquid, and the amount of cleaning liquid sprayed in accordance with the workpiece to be cleaned Can be controlled.

(Other embodiments)
In the above example, the present invention is applied to a workpiece cleaning apparatus. The present invention can also be applied to workpiece processing other than cleaning. For example, it can be used as a workpiece drying apparatus.

  In the above example, each work feed fin has a length corresponding to one rotation of the inner peripheral surface of the rotary drum at a predetermined lead pitch. This may be a length of two or more rounds, and a workpiece catching pocket and a work guide stepped portion may be disposed between the work feed fins.
