The pressing member 29 provided on the moving member 26 includes a first cylindrical member 31 having a contact portion 28 formed at the lower end thereof, and a second cylindrical member 31 positioned above the first cylindrical member 31 and held by the bracket 26a. The first cylindrical member 31 is slidably fitted into the second cylindrical member 32. The outer peripheral surface above the contact portion 28 of the first cylindrical member 31 is formed with an uneven surface 33 in which a convex portion 33 a and a concave portion 33 b are continuous, while the lower end of the second cylindrical member 32 is a first portion. A fixing portion 34 for fixing the cylindrical member 31 with an arbitrary insertion amount is provided. The uneven surface 33 and the fixing portion 34 constitute fixing means for fixing the first cylindrical member 31 and the second cylindrical member 32.
[0014]
The fixing portion 34 has a holding block 34a whose diameter is larger than that of the second cylindrical member 32, and an engaging member that is held by the holding block 34a and can move forward and backward with respect to the concave and convex surface 33 and engages with the concave portion 33b. And two L-shaped engagement plates 34b. One of the engagement plates 34b is engaged with the recess 33b to fix the first cylindrical member 31 to the second cylindrical member 32. It is supposed to let you.
[0015]
A long hole larger than the outer diameter of the first cylindrical member 31 is formed in the long surface of the long surface of the L-shaped engagement plate 34b in the longitudinal direction, and a length smaller than this is adjacent to the long hole. A hole is formed. As shown in FIG. 3C, the engagement plate 34b is supported on the upper and lower portions of the holding block 34a so as to be slidable in the longitudinal direction of the long surface. In FIG. 3C, only the lower portion is shown), and the short surface faces the peripheral surface of the holding block 34a. This short surface is urged in a direction to be separated from the holding block 34a by a spring 34c provided on the peripheral surface of the holding block 34a, thereby counteracting the long hole penetrating the first cylindrical member 31. The inner edge on the direction side is brought into contact with the concavo-convex surface 33 of the first cylindrical member 31. In addition, a stopper pin 34d erected on the holding block 34a is passed through the other small elongated hole so as to restrict the amount of movement of the engagement plate 34b in the direction opposite to the biasing direction by the spring 34c. It has become. That is, when the engagement plate 34 b is pushed against the urging force of the spring 34 c, the inner edge on the urging direction side of the elongated hole through which the first cylindrical member 31 passes comes into contact with the first cylindrical member 31. There is no regulation.
[0016]
The engaging plate 34b has a thickness that allows the engaging plate 34b to be engaged with the concave portion 33b. Further, the engaging plates 34b are arranged so that the short surfaces thereof are opposed to each other and are urged by the spring 34c. When the inner edge of the elongated hole of the engagement plate 34b is in the recess 33b of the concavo-convex surface 33, the other engagement plate 34b is dimensioned to contact the projection 33a in the longitudinal direction of the first cylindrical member 31. The positions are shifted. With this configuration, the amount of projection of the short surface of the engaging plate 34b that has entered the concave portion 33b from the peripheral surface of the holding block 34a is such that the short surface of the engaging plate 34b that is in contact with the convex portion 33a. By pushing the shorter surface, which is larger than the protruding amount and is larger than the protruding amount, against the urging force of the spring 34c, the engagement with the recess 33b is released and the first cylindrical member 31 can move in the longitudinal direction. . In this state, if the first tubular member 31 is moved and moved, the amount of insertion into the second tubular member 32 can be changed. However, as soon as the first tubular member 32 is moved, it is in contact with the other convex portion 33a. Since the mating plate 34b enters the adjacent concave portion 33b by the urging force of the spring 34c, it is possible to adjust the amount of insertion with a small pitch and fine adjustment can be performed with high accuracy. Moreover, there is no risk that the first cylindrical member 31 will fall as soon as the engagement is released, and workability is good. A scale 33c is displayed on the concavo-convex surface 33 so as to be a guide for the amount of movement.

The operation of the air cleaner and the container holding device according to the above configuration will be described.
When the rotating body 10 included in the air cleaner 1 is driven to rotate, each container holding device 12 keeps the container table 13 horizontal in the cleaning section indicated by the arrow E while revolving, and is inverted 180 degrees in the inversion section indicated by the arrow D. The In the container holding device 12 that moves in the cleaning section, the moving member 26 of the holding unit 14 located on the upper side is lifted by the cam 30a, so that the pressing member 29 is lifted and the container 3 is supplied below. Thereafter, since the moving member 26 is quickly lowered and disengaged from the cam 30a, the moving member 26 is urged by the spring 27 and the contact portion 28 is pressed against the upper end of the mouth of the container 3, so that the container base 13 and the contact portion 28 are pressed. Holds the container 3. On the other hand, on the lower side of the container holding device 12 that moves in the cleaning section, the container 3 held by the container table 13 and the contact portion 28 is moved in an inverted state, and the elevating member 20 that moves together is lifted by the cam 22b. Then, the air pipe 19 is inserted into the container 3 through the insides of the second cylindrical member 32, the first cylindrical member 31, and the contact portion 28 that constitute the pressing member 29. As a result, compressed air is blown from the air pipe 19 into the container 3, and the suction nozzle 18 causes the inside of the container 3 to pass through the contact portion 28, the first cylindrical member 31, and the second cylindrical member 32 inside the hollow portion. Is sucked out and the foreign matter in the container 3 is discharged. Further, in the reversing section, the container holding device 12 is reversed 180 degrees by the groove cam 17b, so that the container 3 supplied to the upper side of the container holding device 12 in the cleaning section is reversed to the lower side of the container holding device 12 The container 3 that has been cleaned and is located below the container holding device 12 in the cleaning section and has already been cleaned is inverted to the upper side of the container holding device 12 and is discharged out of the machine by the discharge star wheel 5. The
[0018]
In such a cleaning operation, when the container 3 having a different height from that of the conventional container 3 is cleaned, the insertion amount of the first cylindrical member 31 with respect to the second cylindrical member 32 is changed for all the pressing members 29. More specifically, in the case of changing to a container 3 having a higher height than before, the first cylindrical member 31 is moved to the second cylinder while alternately pressing the engagement plates 34b of the fixing portion 34 of the second cylindrical member 32. The required amount is inserted into the shaped member 32 to shorten the entire length of the pressing member 29. In this case, the proper insertion amounts of the first cylindrical member 31 and the second cylindrical member 32 are examined in advance for each container type, and the scale 33c is adjusted as a guideline. Moreover, when changing to the container 3 whose height is lower than before, the first tubular member 31 is moved to the second tubular member while alternately pushing the engagement plates 34b of the fixing portions 34 of the second tubular member 32. The required amount is extracted from 32 and the entire length of the pressing member 29 is increased. Thus, since the length of the pressing member 29 can be changed according to the change in the height of the container 3, it is possible to use containers having different heights without replacement of the pressing member as in the prior art.
